Description

Anti-oxidation environment control system with automatic display of aging status

The present invention relates to an anti-oxidation environment control system, and more particularly to an anti-oxidation environment control system having the function of automatically displaying the aging state.

Since some items or raw materials are very sensitive to environmental changes, once the environment changes, these items or raw materials will deteriorate or be damaged. Therefore, they need to be stored in a specific environment to be preserved for a long time. In addition, for some products (such as electronic products), since they may need to be used in a variety of different climate environments, they need to be placed in a variety of different test space environments (including general test environments or extreme test environments) for a period of time to observe whether they can still operate normally.

Because of the need to preserve the above-mentioned items or raw materials, and the need to test the operating environment of some of the above-mentioned products, environmental control systems and equipment have come into being. Generally speaking, an environmental control system can usually provide a space and control at least one of the environmental parameters such as temperature, relative humidity, pressure, oxygen concentration and light flux in the space, so that the space becomes a controlled environmental control space. When the controlled environmental parameters include relative humidity or oxygen concentration, the space becomes a controlled antioxidant environment control space.

Specifically, the antioxidant environment control system is usually equipped with at least one environment parameter control module, and a preset or manually set environment parameter control range. Through the operation of the environment parameter control module, the environment parameters in the antioxidant environment control space can be controlled within the environment parameter control range. This can meet the storage requirements of the above-mentioned items or raw materials, as well as the operating environment testing requirements of some of the above-mentioned products.

In the existing antioxidant environment control system, although most of them are equipped with a fault detection module to automatically send an alarm message when a system fault is detected, the antioxidant environment control system is a gradual aging process from normal operation to failure. In the existing technology, there is a general lack of real-time monitoring of the aging process, so when the antioxidant environment control system fails, the fault can only be eliminated in the shortest time.

In order to meet the need for troubleshooting in the shortest possible time, sufficient maintenance parts or consumables are often stored, and sufficient maintenance personnel are organized or the third party is required to organize sufficient support personnel to be on standby at any time. However, this will not only take up a large storage space for maintenance parts or consumables, but also cost a high maintenance labor cost.

In addition, when the antioxidant environmental control system ages to a certain extent, the operating performance of the environmental parameter control module tends to decline, resulting in higher energy costs to barely continue to control the environmental parameters in the antioxidant environmental control space within the environmental parameter control range. This will not only lead to an increase in the operating cost of the environmental control system, but also fail to fulfill the social responsibility of energy conservation and carbon reduction.

In view of the fact that in the prior art, there are generally problems such as the need to occupy a large storage space for maintenance components or consumables, high maintenance labor costs, increased operating costs of environmental control systems, and violations of social responsibility for energy conservation and carbon reduction; the main purpose of the present invention is to provide an anti-oxidation environmental control system with an automatic display of aging status, which can regularly monitor and display the aging status of the anti-oxidation environmental control system and express it in the form of an aging index, so that the user of the environmental control system can have sufficient processing time to take corresponding measures to solve the above-mentioned problems before a failure occurs.

The present invention adopts a necessary technical means to solve the problems of the prior art, which is to provide an anti-oxidation environment control system with an automatic display of aging status (hereinafter referred to as the "anti-oxidation environment control system"). The anti-oxidation environment control system includes an anti-oxidation environment control box, at least one environment parameter timing sensor, a data storage device, a computing device and a display.

The antioxidant environment control box has an antioxidant environment control space for storing at least one object, and is used to adjust an antioxidant environment parameter of the antioxidant environment control space during operation, so as to control the antioxidant environment parameter within an environment parameter control range. The environment parameter timing sensor is arranged in the antioxidant environment control space, and each environment parameter timing sensor senses a plurality of antioxidant environment sensing parameters in the antioxidant environment control space at a plurality of sensing times in a sensing cycle when the antioxidant environment control box is in operation. The data storage device is communicatively connected to the environment parameter timing sensor, and is used to receive and store the sensing time and the corresponding antioxidant environment sensing parameter.

The computing device is installed with a computing program and is communicatively connected to the data storage device to retrieve the sensing time and the corresponding antioxidant environment sensing parameters from the data storage device. The computing device is provided with an environment parameter control range and a statistical computing cycle, and includes an environment parameter comparison module and an aging index computing module after executing the computing program.

The environmental parameter comparison module is used to extract a corresponding start deviation control time and a maximum deviation time in the sensing time when the antioxidant environmental sensing parameter begins to deviate from the environmental parameter control range and reaches a relative extreme value of the environmental parameter, thereby obtaining a maximum deviation control time interval. When the antioxidant environmental sensing parameter falls into the environmental parameter control range again from the relative extreme value of the environmental parameter after sequential comparison, a corresponding return control time in the sensing time is extracted to obtain a return control time interval, and the above process is defined as a deviation control cycle.

The aging index calculation module receives the m maximum deviation control time intervals and m return control time intervals corresponding to the m deviation control cycles included in the first statistical calculation cycle, and receives the n maximum deviation control time intervals and n return control time intervals corresponding to the n deviation control cycles included in the most recently completed r-th statistical calculation cycle. In each deviation control cycle, when the antioxidant environment sensing parameters fall into the environment parameter control range again, an initial regulation capacity consumption rate (Initial Exhaust Rate of Modulation Capacity) is calculated according to a first formula, a current regulation capacity consumption rate (Current Exhaust Rate of Modulation Capacity) is calculated according to a second formula, and an aging index representing the aging state is calculated according to a third formula. The display is installed in the anti-oxidation environment control box and is communicatively connected to the computing device to receive and display the aging index.

The first formula is: ; The second formula is: ; The third formula is: .

Among them, ERmci is the initial regulation capacity consumption rate corresponding to the first statistical operation cycle; Tai is the maximum deviation control amount time interval of the i-th deviation control cycle in the first statistical operation cycle; Tbi is the return control time interval of the i-th deviation control cycle in the first statistical operation cycle; ERmcc is the current regulation capacity consumption rate corresponding to the r-th statistical operation cycle; Taj is the maximum deviation control amount time interval of the j-th deviation control cycle in the r-th statistical operation cycle; Tbj is the return control time interval of the j-th deviation control cycle in the r-th statistical operation cycle; and AI is the aging index. Antioxidant environmental parameters include relative humidity or oxygen concentration. r, m, n, i and j are all natural numbers, and r is greater than or equal to 2.

Among the subsidiary technical means derived from the above necessary technical means, the preferred one is that the computing device may include a first fault judgment module after executing the computing program, and is provided with an allowable return control time ratio, and the first fault judgment module is used to judge the antioxidant environment control box as being in a timeout deviation control fault state when it is judged that a timeout deviation control condition is met, and transmit a timeout deviation control fault signal accordingly.

After executing the calculation program, the calculation device may further include a second fault judgment module, which has an allowable deviation control increase. The second fault judgment module includes an average extreme value calculation unit and a comparison judgment unit.

The average extreme value calculation unit is used to calculate an average relative extreme value of the environmental parameter of s deviation control cycles according to a fourth formula after s deviation control cycles. The comparison judgment unit is used to judge that the antioxidant environment control box is in a severe deviation control fault state when it is judged that a severe deviation control condition is met, and transmit a severe deviation control fault signal accordingly.

Kad , wherein Pea is the relative extreme value of the average environmental parameter; Pet is the relative extreme value of the t-th environmental parameter; Pex is an aggravated deviation extreme value of the antioxidant environmental sensing parameter, which is further deviated from the environmental parameter control range than the s+1-th relative extreme value of the environmental parameter before returning to the environmental parameter control range after reaching the s+1-th relative extreme value of the environmental parameter; and Kad is the allowable deviation control increase, s and t are both natural numbers, and s is greater than or equal to 2.

The antioxidant environment control system may further include an alarm device, which is communicatively connected to the computing device, so as to issue a fault alarm signal when receiving a timeout deviation control fault signal or a serious deviation control fault signal. Preferably, the alarm device further includes a warning light or a warning buzzer, so as to issue an alarm light signal or an alarm sound signal as a fault alarm signal.

The antioxidant environment control system may further include a remote monitoring device, which is communicatively connected to the computing device, so that when receiving a timeout deviation control fault signal or a serious deviation control fault signal, a fault prompt message is played to inform a remote operator operating the remote monitoring device. In addition, the antioxidant environment control system may also include a setting operation interface, which is communicatively connected to the environmental parameter timing sensor and the computing device, and is used to set the sensing cycle, the environmental parameter control range and the statistical computing cycle.

The remote monitoring device can be a mobile phone, a personal computer, a desktop computer, a tablet computer or an industrial computer. The environmental parameter timing sensor can be a relative humidity timing sensor or an oxygen concentration timing sensor. The data storage device can be a local data collector or a data storage server. The computing device can be an embedded computer in an environmental control box, an industrial computer, a personal computer, a laptop or a computing server.

In summary, in the anti-oxidation environment control system with the automatic display of aging status function provided by the present invention, the current adjustment capacity consumption rate of the most recently completed r-th statistical calculation cycle of the anti-oxidation environment control system is compared with the initial adjustment capacity consumption rate of the first statistical calculation cycle to obtain the aging status of the anti-oxidation environment control system after the most recently completed statistical calculation cycle compared to the first statistical calculation cycle, and the aging index is specifically presented on the display installed in the anti-oxidation environment control box in the form of an aging index, so that a proximal operator who operates the anti-oxidation environment control box at the proximal end can grasp the aging status of the anti-oxidation environment control system at any time. Through the above technical means, the near-end operator can predict the remaining adjustment capacity and the remaining time to maintain normal operation before a fault occurs, and obtain sufficient response time to prepare troubleshooting measures, such as making an appointment to perform maintenance or replacement of consumables by themselves or outsourcing.

From the above description, it can be seen that through the practice of the present invention, not only does it not need to occupy a large storage space for maintenance components or consumables, but it also does not need to prepare a large number of maintenance personnel to be on standby to troubleshoot at any time, and it can further ensure that the antioxidant environment control system operates at reasonable working efficiency and energy costs. Undoubtedly, compared with the previous technology, the present invention can obviously achieve the effects of reducing the storage cost of maintenance components or consumables, reducing maintenance labor costs, reducing system operation costs, and fulfilling the social responsibility of "saving energy and reducing carbon" and many other effects.

Since the anti-oxidation environment control system with the function of automatically displaying the aging status provided by the present invention can be widely used in various existing anti-oxidation environment control systems, we will not describe them one by one here, but only list one of the better embodiments for specific explanation, and this embodiment is only used to conveniently and clearly assist in explaining the purpose and effect of the embodiment of the present invention.

Please refer to Figures 1 to 3, the first Figure is a functional block diagram of the anti-oxidation environment control system with automatic display of aging status function provided by the better embodiment of the present invention; the second Figure is a schematic diagram showing the relative position relationship between the anti-oxidation environment control box of the anti-oxidation environment control system with automatic display of aging status function provided by the better embodiment of the present invention and the surrounding related components when it is opened; the third Figure is a schematic diagram showing the relative position relationship between the anti-oxidation environment control box of the anti-oxidation environment control system with automatic display of aging status function provided by the better embodiment of the present invention and the surrounding related components when it is closed. As shown in the first to third figures, an anti-oxidation environment control system with an automatic display of aging status function (hereinafter referred to as "anti-oxidation environment control system") 100 includes an anti-oxidation environment control box 1, one or more environmental parameter timing sensors (only one environmental parameter timing sensor 2 is drawn as a representative in the figure), a data storage device 3, a computing device 4, a display 5, a setting operation interface 6, an alarm device 7 and a remote monitoring device 8.

The antioxidant environment control box 1 includes a box body 11, two box doors (only one of the box doors 12 is marked in the figure) and an antioxidant environment parameter adjustment module 13. When the box door 12 is covered on the box body 11, the box body 11 and the box door 12 can enclose a closed space. After applying an antioxidant adjustment control method to the closed space using the antioxidant environment parameter adjustment module 13, an antioxidant environment parameter of the closed space can be adjusted to control the antioxidant environment parameter of the closed space within an environment parameter control range, so that the closed space is transformed into an antioxidant environment control space ECS for storing at least one object 200.

In the present invention, the antioxidant regulation control means adopted are mainly the relative humidity regulation control and oxygen concentration regulation control which are currently widely used. Therefore, the antioxidant environment parameter regulation module 13 can be a relative humidity regulation module or an oxygen concentration regulation module. Since the relative humidity regulation module or the oxygen concentration regulation module are both mature and commonly used prior technologies, they are not the main technical means of the present invention. The following will briefly describe their basic operation mode and will not elaborate on their complete technical content.

Taking the relative humidity control module as an example, it usually includes a dehumidification unit, a relative humidity sensor and a controller, and works with a fan and a valve. The dehumidification unit usually contains moisture-absorbing balls, moisture-absorbing cotton or moisture-absorbing cloth. The controller usually sets a relative humidity control range. When the controller determines that the relative humidity in the antioxidant environment control space ECS sensed by the relative humidity sensor is too high, the controller can control the fan speed and valve opening and closing to introduce the gas with high relative humidity in the antioxidant environment control space ECS into the dehumidification unit for dehumidification, and generate dry air with lower relative humidity, and then return the dry air to the antioxidant environment control space ECS, thereby reducing the relative humidity in the antioxidant environment control space ECS. When the relative humidity is low, the dehumidification unit and the fan will temporarily stop operating to save energy consumption. At the same time, dehumidify the moisture-absorbing balls, moisture-absorbing cotton or moisture-absorbing cloth in the dehumidification unit to restore some of the dehumidification capacity.

Taking the oxygen concentration control module as an example, it usually includes a high-pressure gas cylinder, an oxygen concentration sensor and a controller, and works in conjunction with a valve (or a pressurized gas charging mechanism, such as a pressurized gas charging pump). High-pressure gas cylinders usually store high-pressure non-oxygen stable gas (nitrogen is used as an example below). The controller usually sets an oxygen concentration control range. When the controller determines that the oxygen concentration in the antioxidant environment control space ECS sensed by the oxygen concentration sensor is too high, it can control one of the valves to open and reduce the oxygen concentration in the antioxidant environment control space ECS to a low level. The gas is discharged and another valve is controlled to open, so that high-pressure nitrogen is automatically filled into the antioxidant environment control space ECS by the pressure difference, or the inflation mechanism is used to increase the pressure difference to fill the high-pressure nitrogen into the antioxidant environment control space ECS. The increase in nitrogen concentration can dilute the oxygen concentration, so that the oxygen concentration in the antioxidant environment control space ECS decreases.

However, both the relative humidity control module and the oxygen concentration control module have their adjustment capacity. For the relative humidity control module, its adjustment capacity mainly depends on the saturated water absorption of the moisture-absorbing balls, moisture-absorbing cotton or moisture-absorbing cloth in the dehumidification unit. After a period of operation, the moisture-absorbing balls, moisture-absorbing cotton or moisture-absorbing cloth in the dehumidification unit will absorb water. Even if the current water absorption of the moisture-absorbing balls, moisture-absorbing cotton or moisture-absorbing cloth can be reduced by heating and dehumidification, and part of its water absorption capacity can be restored, it is still inevitable to lose part of its water absorption capacity. Therefore, dividing the current water absorption by the saturated water absorption can be regarded as a (current) adjustment capacity loss rate.

As the regulation capacity loss rate increases, it means that the dehumidification unit's water absorption capacity decreases, so the fan needs to run at a higher speed to pump a larger amount of air to the dehumidification unit for dehumidification, so that the relative humidity can be reduced back to the relative humidity control range within a specific time. As a result, the relative humidity regulation module must consume higher energy to perform the regulation function.

As for the oxygen concentration regulating module, its regulating capacity mainly depends on the amount of nitrogen that can be filled into the antioxidant environment control space ECS in the high-pressure gas cylinder. After a period of operation, part of the nitrogen will be filled into the antioxidant environment control space ECS, resulting in the loss of some nitrogen. Therefore, the current remaining amount of nitrogen that can be filled into the antioxidant environment control space ECS divided by the initial amount of nitrogen that can be filled into the antioxidant environment control space ECS can be regarded as another (current) regulating capacity consumption rate.

As the regulation capacity consumption rate increases, the pressure in the high-pressure gas cylinder decreases, and the pressure difference between the high-pressure gas cylinder and the antioxidant environment control space ECS decreases. Therefore, the inflation mechanism needs to apply higher power to pressurize and inflate, and fill more nitrogen into the antioxidant environment control space ECS, so that the oxygen concentration can be reduced back to the oxygen concentration control range within a specific time. As a result, the oxygen concentration regulation module must consume higher energy to perform the regulation function.

The environmental parameter timing sensor 2 is arranged in the antioxidant environment control space ECS. The so-called environmental parameter timing sensor 2 is a sensor that can sense environmental parameters regularly by means of a built-in timer or receiving an external clock signal. When the antioxidant environment control box 1 is in operation, each environmental parameter timing sensor 2 senses a plurality of antioxidant environment sensing parameters in the antioxidant environment control space ECS in a sensing cycle at a plurality of sensing times. The environmental parameter timing sensor 2 can be a relative humidity timing sensor or an oxygen concentration timing sensor. In this embodiment, the environmental parameter timing sensor 2 is a relative humidity timing sensor.

The data storage device 3 can be a proximal data collector installed in the antioxidant environment control box 1, or a remote data storage server, and is communicatively connected to the environmental parameter timing sensor 2 to receive and store the sensing time and the corresponding antioxidant environment sensing parameter (relative humidity sensing parameter in this embodiment).

The computing device 4 can be an embedded computer in an environmental control box, an industrial computer, a personal computer, a notebook computer or a computing server, which is installed with a computing program AP and is communicatively connected to the data storage device 3 to extract the sensing time and the corresponding antioxidant environmental sensing parameters from the data storage device 3. At the same time, the computing device 4 is also provided with the above-mentioned environmental parameter control range and a statistical computing cycle, and after executing the computing program AP, it includes an environmental parameter comparison module 41, an aging index computing module 42, a first fault judgment module 43 and a second fault judgment module 44.

Since the environmental parameter comparison module 41, the aging index calculation module 42, the first fault judgment module 43 and the second fault judgment module 44 are all generated after the operation program AP, in essence, the environmental parameter comparison module 41, the aging index calculation module 42, the first fault judgment module 43 and the second fault judgment module 44 can be regarded as the main program, sub-program, plug-in program in the operation program AP or the derivative application program generated after the operation program AP is executed.

The environmental parameter comparison module 41 is used to extract a corresponding start deviation control time and a maximum deviation time in the sensing time when the antioxidant environmental sensing parameter begins to deviate from the environmental parameter control range and reaches a relative extreme value of the environmental parameter, thereby obtaining a maximum deviation control time interval. When the antioxidant environmental sensing parameter falls into the environmental parameter control range again from the relative extreme value of the environmental parameter after sequential comparison, a corresponding return control time in the sensing time is extracted, thereby obtaining a return control time interval, and the above process is defined as a deviation control loop.

Please refer to the fourth figure, which shows the curve of the relationship between relative humidity and time change before and after the first deviation control cycle. As shown in the fourth figure, in this embodiment, the environmental parameter timing sensor 2 senses a relative humidity sensing parameter every minute, that is, the first relative humidity sensing parameter is sensed in the first minute. After the antioxidant environment control box 1 is started for 150 minutes, a total of 150 relative humidity sensing parameters are generated.

In this embodiment, the environmental parameter control range is the relative humidity control range formed between the lower control boundary value LCB (4.6%RH) and the upper control boundary value UCB (5.3%RH). When comparing, it is found that at 77 minutes, due to the opening of the chamber door 12 (marked in the first figure), the relative humidity sensing parameter begins to be greater than the upper control boundary value UCB, so the 77th minute can be defined as the start deviation control time of the first deviation control cycle. Afterwards, when the time is sequentially compared to around the 81st minute, the first relative extreme value of the environmental parameter Pe1 (the first relative extreme value of relative humidity) can be compared to be 18.9, so the 81st minute can be defined as the maximum deviation time of the first deviation control cycle. During this period, after the door 12 is closed, the relative humidity sensing parameter begins to decrease until the 118th minute, when the relative humidity sensing parameter begins to be lower than the upper control boundary value UCB and returns to the relative humidity control range again, so the 118th minute can be defined as the return control time of the first deviation control cycle.

Then, by subtracting 77 minutes from 81 minutes, we can get the maximum deviation control time interval Ta1 of the first deviation control loop as 4 minutes, and by subtracting 81 minutes from 118 minutes, we can get the return control time interval Tb1 of the first deviation control loop as 37 minutes.

Please refer to the first, fifth and sixth figures together, wherein the fifth figure is a curve diagram showing the relationship between relative humidity and time variation in the first statistical operation cycle, and the sixth figure is a curve diagram showing the relationship between relative humidity and time variation in the second statistical operation cycle. The aging index calculation module 42 receives the m maximum deviation control intervals and m return control intervals corresponding to the m deviation control cycles included in the first statistical calculation cycle, receives the n maximum deviation control intervals and n return control intervals corresponding to the n deviation control cycles included in the most recently completed rth statistical calculation cycle, and in each deviation control cycle, when the antioxidant environment sensing parameters fall into the environment parameter control range again, calculates an initial modulation capacity consumption rate (Initial Exhaust Rate of Modulation Capacity) according to a first formula, calculates a current modulation capacity consumption rate (Current Exhaust Rate of Modulation Capacity) according to a second formula, and calculates an aging index representing the aging state according to a third formula.

； 第二公式為：

；第三公式為：AI=(ERmcc-ERmci)/ERmci˙100%。 The first formula is:

; The second formula is:

; The third formula is: AI =( ERmcc - ERmci )/ ERmci ˙100%.

Among them, ERmci is the initial regulation capacity consumption rate corresponding to the first statistical operation cycle; Tai is the maximum deviation control time interval of the ith deviation control cycle in the first statistical operation cycle; Tbi is the return control time interval of the ith deviation control cycle in the first statistical operation cycle; ERmcc is the current regulation capacity consumption rate corresponding to the rth statistical operation cycle. The energy saving capacity consumption rate; Taj is the maximum deviation control value time interval of the jth deviation control cycle in the rth statistical operation cycle; Tbj is the return control time interval of the jth deviation control cycle in the rth statistical operation cycle; and AI is the aging index. The anti-oxidation environment parameters include relative humidity or oxygen concentration. r, m, n, i and j are all natural numbers, and r is greater than or equal to 2.

In the present embodiment, two statistical calculation cycles have been completed. The aging index calculation module 42 can receive the three maximum deviation control time intervals Ta1, Ta2 and Ta3 (4 minutes, 3 minutes and 3 minutes respectively) and the three return control time intervals Tb1, Tb2 and Tb3 (37 minutes, 34 minutes and 32 minutes respectively) corresponding to the three deviation control loops included in the first statistical calculation cycle, and receive the three maximum deviation control time intervals Ta4, Ta5, Ta6 (4 minutes, 3 minutes and 3 minutes respectively) and the three return control time intervals Tb4, Tb5, Tb6 (38 minutes, 36 minutes and 33 minutes respectively) corresponding to the three deviation control loops included in the most recently completed second statistical calculation cycle. Therefore, r=2, m=3 and n=3.

For the sake of numbering consistency, the maximum deviation control time interval Taj in the second statistical operation cycle from 1 to n (=3) should correspond to the maximum deviation control time interval Ta4, Ta5 and Ta6 respectively, and the return control time interval Tbj in the second statistical operation cycle from 1 to n (=3) should correspond to the return control time interval Tb4, Tb5 and Tb6 respectively.

According to the first formula, it can be calculated that: ERmci=(37+34+32)/(4+3+3)=10.3, which means that the initial adjustment capacity consumption rate in the first statistical calculation cycle is 10.3; according to the second formula, it can be calculated that: ERmcc=(38+36+33)/(4+3+3)=10.7, which means that the current adjustment capacity consumption rate in the second statistical calculation cycle is 10.7. Then, the third formula can be used to calculate AI=(10.7-10.3)/10.3.100%=3.9%, which means that the aging index is 3.9%.

The display 5 can be an embedded touch display, an eight-segment display or an external display installed in the antioxidant environment control box 1, and is communicatively connected to the computing device 4 to receive and display the aging index. A proximal operator 300 located near the antioxidant environment control box 1 can predict the remaining adjustment capacity and the remaining time to maintain normal operation of the antioxidant environment parameter adjustment module 13 by viewing the aging index, and obtain sufficient response time to prepare troubleshooting measures, such as making an appointment to perform maintenance or replacement of consumables by oneself or outsourcing.

Please refer to the first, fifth, sixth and seventh figures together, wherein the seventh figure is a curve showing the relationship between relative humidity and time variation when a timeout deviation control fault state is generated after six deviation control cycles. In addition to calculating the aging index, the calculation device 4 can also calculate and analyze whether the antioxidant environment control box is in a fault state. The fault states that can be judged in the present invention include two types: a timeout deviation control fault state and a serious deviation control fault state. As for the judgment means of the timeout deviation control fault state, the computing device 4 can set an allowable return control time ratio by a preset method or a manually set method, and when the first fault judgment module 43 judges that a timeout deviation control condition is met, the antioxidant environment control box 1 is judged to be in a timeout deviation control fault state, and a timeout deviation control fault signal S1 is transmitted accordingly.

Kar；其中，Tak為完成第k-1個偏離控制循環後之第k個上述極大偏離控制量時距；Tfk為對應於第k個上述極大偏離控制量時距後之抗氧化環境感測參數持續未落入環境參數控制範圍之一持續偏離控制時距；以及Kar為允許返回控制時間比值，且k為自然數。 The timeout deviation control condition is: (Tfk)/(Tak)

Kar ; wherein, Tak is the kth maximum deviation control value time interval after completing the k-1th deviation control cycle; Tfk is a continuous deviation control time interval corresponding to the kth maximum deviation control value time interval during which the antioxidant environment sensing parameter continues to fail to fall into the environmental parameter control range; and Kar is the allowable return control time ratio, and k is a natural number.

In this embodiment, the allowable return control time ratio (Kar) is set to 40. After 2 statistical calculation cycles and 6 deviation control cycles, the 7th maximum deviation control time interval Ta7 generated between the 780th minute and the 783rd minute is 3 minutes. After the 7th maximum deviation control time interval Ta7, until the 910th minute, the antioxidant environment sensing parameter continued to not fall into the environmental parameter control range. Therefore, in this case, k=7, so the continuous deviation control time interval Tf7 corresponding to the 7th maximum deviation control time interval Ta7 is 127 minutes. Since 127/3=42.3 is greater than the allowable return control time ratio (Kar=40), it means that the antioxidant environment control box 1 cannot adjust the relative humidity within the relative humidity control range between the lower control boundary value LCB (4.6%RH) and the upper control boundary value UCB (5.3%RH) within the allowable time, so it can be judged as being in a timeout deviation control fault state.

Please refer to the first, fifth, sixth and eighth figures, wherein the eighth figure is a curve showing the relationship between relative humidity and time variation when a severe deviation control fault state is generated after six deviation control cycles. For the judgment means of the severe deviation control fault state, the calculation device 4 can set an allowable deviation control increase by a preset method or a manually set method. The second fault judgment module 44 includes an average extreme value calculation unit 441 and a comparison judgment unit 442.

The average extreme value calculation unit 441 is used to calculate an average relative extreme value of an environmental parameter of s deviation control cycles according to a fourth formula after s deviation control cycles. The comparison judgment unit is used to judge that the antioxidant environment control box is in a severe deviation control fault state when it is judged that a severe deviation control condition is met, and transmit a severe deviation control fault signal S2 accordingly.

；嚴重偏離控制條件為：|Pex-Pea|

Kad，其中，Pea為該平均環境參數相對極值；Pet為第t個環境參數相對極值；Pex為該些抗氧化環境感測參數中，達到第s+1個上述環境參數相對極值後，在回到該環境參數控制範圍前又產生較第s+1個上述環境參數相對極值更偏離該環境參數控制範圍之一加劇偏離極值；以及Kad為允許偏離控制增幅，s與t皆為自然數，且s大於等於2。 The fourth formula is:

; Severe deviation control conditions are: |Pex-Pea|

Kad , wherein Pea is the relative extreme value of the average environmental parameter; Pet is the relative extreme value of the t-th environmental parameter; Pex is an aggravated deviation extreme value of the antioxidant environmental sensing parameters, which deviates further from the environmental parameter control range than the s+1-th relative extreme value of the environmental parameter before returning to the environmental parameter control range after reaching the s+1-th relative extreme value of the environmental parameter; and Kad is the allowable deviation control increase, s and t are both natural numbers, and s is greater than or equal to 2.

In this embodiment, the allowable deviation control increase (Kad) is 10%RH. After 2 statistical calculation cycles and 6 deviation control cycles, the 7th environmental parameter relative extreme value Pe7 (7th relative humidity relative extreme value) generated at the 783rd minute is 19.0%RH. Before returning to the environmental parameter control range, although the timeout deviation control fault state has not occurred, an aggravated deviation extreme value (aggravated deviation relative humidity extreme value) Pex=37.7%RH is generated, which is more deviated from the environmental parameter control range than the 7th environmental parameter relative extreme value. In this case, s is equal to 6.

From the fifth and sixth figures, we can see that the relative extreme values of the environmental parameters (relative extreme values of relative humidity) corresponding to the six deviation control cycles are 18.9%RH, 16.4%RH, 15.4%RH, 18.9%RH, 19.0%RH and 17.4%RH respectively.

(18.9%RH+16.4%RH+15.4%RH+18.9%RH+19.0%RH+17.4%RH)/6=17.67%RH. It means that the average relative extreme value of the environmental parameter Pea of the completed 6 deviation control cycles is equal to 17.67%. At the 7th relative extreme value of the environmental parameter Pe7 (the 7th relative humidity relative extreme value is 19.0%RH), before returning to the environmental parameter control range, an aggravated deviation extreme value (aggravated deviation relative humidity extreme value) Pex=37.7%RH is generated, which is further away from the environmental parameter control range than the 7th relative extreme value of the environmental parameter (19.0%RH).

10%RH，滿足嚴重偏離控制條件，可判斷出抗氧化環境控制箱1處於嚴重偏離控制故障狀態。 |37.7%RH-17.67%RH|

10%RH, meeting the severe deviation control conditions, it can be judged that the antioxidant environment control box 1 is in a severe deviation control fault state.

The setting operation interface 6 can be a touch panel, operation panel or operation button set in the antioxidant environment control box 1, and is communicatively connected to the antioxidant environment parameter adjustment module 13, the environment parameter timing sensor 2 and the computing device 4, for setting the sensing cycle, the environment parameter control range and the statistical calculation cycle. In addition, the setting operation interface 6 can also be used to set the allowable return control time ratio and the allowable deviation control increase. Thus, a near-end operator 300 located near the antioxidant environment control box 1 can transmit the set related parameters to the antioxidant environment parameter adjustment module 13, the environment parameter timing sensor 2 and the computing device 4 respectively by operating the setting operation interface 6.

The alarm device 7 is communicatively connected to the computing device 4, so as to issue a fault alarm signal AS when receiving the timeout deviation control fault signal S1 or the serious deviation control fault signal S2. Preferably, the alarm device 7 may include a warning light 71 and/or a warning buzzer 72, so as to issue a warning light signal and/or an alarm sound signal as the fault alarm signal AS.

The remote monitoring device 8 can be a mobile phone, a personal computer, a desktop computer, a tablet computer or an industrial computer, and is communicatively connected to the computing device 4, so that when receiving the timeout deviation control fault signal S1 or the serious deviation control fault signal S2, a fault prompt message is played to inform a remote operator 400 of the remote monitoring device.

In summary, in the anti-oxidation environment control system 100 with the automatic display of aging status function provided by the present invention, the current adjustment capacity consumption rate of the most recently completed rth statistical operation cycle is used to compare and calculate with the initial adjustment capacity consumption rate of the first statistical operation cycle, so as to obtain the aging status of the anti-oxidation environment control system 100 after the most recently completed statistical operation cycle compared with the first statistical operation cycle, and the aging index is specifically presented on the display 5 set in the anti-oxidation environment control box 1, so that a proximal operator 300 who operates the anti-oxidation environment control box 1 at the proximal end can grasp the aging status of the anti-oxidation environment control system 100 at any time.

Through the above technical means, the near-end operator 300 can predict the remaining adjustment capacity and the remaining time to maintain normal operation before a fault occurs, and obtain sufficient response time to prepare troubleshooting measures, such as making an appointment to perform maintenance or replacement of consumables by himself or outsourcing.

From the above description, it can be seen that through the practice of the present invention, not only does it not need to occupy a large storage space for maintenance components or consumables, but it also does not need to prepare a large number of maintenance personnel to be on standby to troubleshoot at any time, and it can further ensure that the antioxidant environment control system 100 operates at reasonable working efficiency and energy costs. Undoubtedly, compared with the previous technology, the present invention can obviously achieve many effects such as reducing the storage cost of maintenance components or consumables, reducing maintenance labor costs, reducing system operation costs, and fulfilling the social responsibility of "saving energy and reducing carbon".
