A floating system for adjusting energy distribution and wheeled energy supply, and an implementation method thereof, in particular, a method for monitoring energy consumption demand end by monitoring the actual energy consumption demand of the energy demand end, and according to the information obtained by the monitoring, Floating-adjusted energy distribution, and "wheel-controlled supply of energy", a system for floating energy-adjusted energy distribution and wheel-controlled energy supply that effectively improves energy efficiency and its implementation method.

As the issue of energy depletion continues to prolong, how to achieve energy conservation goals through effective management has clearly become the main subject of today's technological development. Taking power supply as an example, the progress of the times has also followed the daily increase in electricity consumption. Therefore, each power supply end has signed a contracted power capacity with each user terminal to limit the power consumption of the user terminal, and the power consumption growth is slowed down. If the user terminal exceeds the contracted power capacity signed by both parties, the user At the end of the day, the amount of the added amount must be paid according to the amount exceeded. For this reason, many users will perform appropriate energy-saving management for their power consumption; please refer to "Figure 1", which is shown in the figure. The power distribution diagram, as shown in the figure, is generally powered by a power supply (such as the power company). Division), the power supply is pulled to the home or commercial area, usually, a power assembly 10 is constructed in the above-mentioned household or commercial area, and then the power is distributed to the power distribution device 111 of each unit 11 in the area (generally called a distribution box) And then, by the power distribution device 111, the power is distributed to each energy consuming device 112 (for example, the lighting device, the information device, the air conditioning device, etc. in the illustration) to supply power; as described above, the conventional power supply configuration There is no such thing as "energy-saving management". After investigation, there are many patent applications for "energy management" as the key technology. Among them, for example, the Republic of China Patent I376855 "Power Consumption Control System and Method", 201248387 "Power Management System and Method", 201215823 "Air Conditioning System Water Side Equipment Energy Saving Control Method", 201207588 "Temperature Priority Control Method for Energy Demand Control and Its Temperature Control System", 201135612 "Sequential Wheel Stop Demand Control" Method, 201015817 "Power Control System and Operation Method", 201027382 "Integrated Information System Air Conditioning Equipment Control Management System", 200722952" The optimization method of the power unloading system, etc., all use the air-conditioning equipment power supply control as the main means of energy saving; in the 201135612 sequential wheel stop demand control method, the figure reveals that the wheel stop is the key to the patents; for example, 201207588 "The temperature priority control method for energy demand control and its temperature control system" shows that the combination of temperature sensing is another key to improving the efficiency of air-conditioning operation. The above cases are mainly controlled by individual air-conditioning equipment. The equipment field is less inked, or only expressed in a simple pictogram; in addition, the energy-saving management system currently visible on the market, before implementation, groups the energy-consuming devices to be placed in the supply area to form Multiple energy consumption groups, and the rated energy consumption of each energy consumption group is preset to be the same, although this embodiment can achieve group supply Electricity, but in actual implementation, the energy consumed by each energy-consuming group may not be the same, because the energy-consuming devices loaded in each energy-consuming group are not necessarily the same, and even if they are identical, they may not be simultaneously opened. However, the common situation is that the energy consumption of some energy-consuming groups may be fully loaded for a long time, while the other energy-consuming groups may only have some energy consumption, so that due to energy The management terminal cannot accurately grasp the real energy consumption requirements of each energy-consuming group, and the benefits of “energy-saving” that can be achieved are limited. In addition to the above-mentioned conventional energy-saving management system, the slightly improved energy-saving management system Further, power supply to each energy-consuming group is provided in turn to improve energy-saving efficiency, but the manager still cannot grasp the real energy consumption situation and needs of each group at any time, for example, when the energy consumption of a certain area belongs to The group is in the situation of stopping the power supply, and a user wants to use an energy-consuming device in the energy-consuming group without knowing, for example, to turn on the light, at this time, the energy-consuming group is The state of the power supply may cause the user to mistakenly think that the lamp is faulty or the switch fails after the situation that the lamp cannot be turned on. Even the test or maintenance of the switch or the lamp is started, so that the electric energy is originally supplied in turn to improve energy saving. The purpose of the effect is that the user has inconvenience in using it. According to this, if the dynamic supply mechanism is used to adjust the overall supply situation, it will be able to improve the problems caused by the implementation of the existing energy-saving management system.

In view of the above problems, the present inventors have been based on years of experience in designing related energy-saving systems, aiming at the construction mode of existing energy-saving management systems and The implementation method, related analysis and research, can design an energy-saving system to solve the above problems; therefore, the main purpose of the present invention is to provide an energy consumption in the monitored area by monitoring actual energy consumption requirements and conditions. The overall energy consumption of the device can be reliably grasped, and after monitoring by the monitoring terminal, it is possible to use the "floating adjustment energy allocation" and the "wheel control supply energy" to effectively improve the energy-saving system and its implementation method.

In order to achieve the above object, the present invention relates to a system for floating energy adjustment and wheeled power supply and a method for implementing the same, wherein the system is mainly provided by a monitoring terminal (or an energy saving management center). a host device, a power consumption monitoring device disposed at a power demanding end, a power distribution device, and one or more energy consuming devices; wherein the host device information is coupled with a wheel control device for controlling power Provided that the wheel-controlled device has an energy-consuming device that instantaneously calculates and dynamically adjusts the power-consuming demand terminals of the wheeled control; the energy-consuming monitoring device of each energy-consuming demand terminal is also connected with the host device by information, whereby The host device can obtain information about the requirements of the energy-consuming devices connected to the energy-consuming monitoring device and the actual energy consumption.

As shown in the figure, the present invention is mainly applicable to the management of energy distribution, and the energy source can be, for example, an electric energy or a water. In the present invention, only the management of electric energy is taken as an example, but not limited thereto; as shown in the figure, the floating adjustment energy distribution and the wheeled control energy supply according to the present invention are provided.

The host device 211 of the center or the energy-saving management center 21 is connected to the information, so that the energy consumption information of each energy-consuming device 221 is transmitted to the host device 211, and accordingly, the manager of the monitoring terminal 21 can obtain the slave host. Presented by device 211 In the data, the power consumption of the energy demand terminal 22 is clearly understood; furthermore, since the host device 211 and the power assembly 20 are in an information connection, if necessary, the host device 211 can be actuated. (or adjusting) the power supply situation of the power assembly 20; the same application mode, if it is in a relatively small area, the host device 211 can directly actuate (or adjust) the power supply situation of the power distribution device 223, for example, for a specific consumption The device can not be powered for a certain period of time; further, as described above, the application of the present invention can further expand the host device 211 of a monitoring terminal 21 corresponding to a plurality of energy-consuming demand terminals (22, 23...), which is applicable to In the case of a large area, or a sub-area management, for example, the host device 211 of the monitoring terminal 21 synchronously manages the power consumption of a plurality of commercial buildings.

Please refer to "Fig. 3", which is a block diagram (1) of the system of the present invention. As shown in the figure, in the normal state, the pre-configured energy consumption value P of the energy demand terminal 22 is already It is preset by the host device 211, and the pre-configured energy consumption value P can be limited by the power consumption limit and the power consumption time limit, for example, the upper limit of the power consumption condition of the energy-consuming device 222 is The energy consumption value P is configured. Further, the present invention has the function of "floating adjustment energy allocation", and the implementation method thereof is as follows: (1) The actual power consumption of the energy consumption device 222 is continuously uploaded to the energy consumption monitoring device. 221, which may be a completely un-consumption state, a sustained energy-consuming state, etc.; (2) the energy consumption monitoring device 221 records the pre-configured energy consumption value P provided by the host device, and also records each energy consumption.

Please refer to FIG. 4, which is a block diagram (2) of the system of the present invention. As shown in the figure, the present invention can further synchronize a plurality of energy-consuming demand terminals with a host device 211 of the monitoring terminal 21 ( 22, 23, 24...) to monitor and perform "floating adjustment energy allocation"; further, another function of the present invention is particularly suitable for simultaneously monitoring multiple energy demand terminals (22, 23, 24...) In this case, this function is "wheel control supply of energy". In practice, the energy consumption demand terminals (22, 23, 24...) are different due to the power usage. Therefore, the host device 211 is initially configured in the pre-configuration. When the energy consumption value P is different, most of them will be different. Then, according to experience, the actual energy consumption results of the energy consumption demand terminals (22, 23, 24...) are usually different from the original pre-configured energy consumption value P. It may be much lower than the pre-configured energy consumption value P. It is also possible that the original pre-configured energy consumption value P is insufficient. However, with the function of the "floating adjustment energy allocation" of the present invention, the pre-configured energy consumption value is After P is adjusted to "adjusted energy consumption value A", a single energy demand side (for example, 22) can be obtained. To solve the problem, but the excess unused energy consumption is obviously idle, or its insufficient energy consumption, it needs to wait for the next "floating adjustment energy allocation" to be solved, so that When simultaneously monitoring a plurality of energy-consuming demand terminals (22, 23, 24...), the functions of "wheel-controlled energy supply" are further synchronized; and the method of "wheel-controlling energy supply" is After the actual energy consumption information (22, 23, 24, ...) is respectively transmitted back to the host device 211 of the monitoring terminal 21, the execution method is as follows, please refer to "figure 5", in the figure Shown is a schematic diagram of the implementation method of the present invention: energy consumption sorting ST1: the host device 211 of the monitoring terminal 21 will each consume energy demand The actual energy consumption information of the terminals (22, 23, 24...) is sorted, and please refer to "Fig. 6". The figure shows the energy consumption sorting map of the present invention. According to the above, the host device of the monitoring terminal 21 After obtaining the energy consumption information of each energy consuming device (X, Y, Z), the energy consumption information of the energy consuming device X is 80 WHr, and the energy consumption information of the energy consuming device Y is 500 WHr, and the energy consuming device Z The energy consumption information is 350 WHr. According to this, the host device 211 actively sorts the energy consumption information, and the sorting result is S1 as shown in the figure; the energy consumption sequentially groups ST2: the host device 211 of the monitoring terminal 21 further According to the sorting result S2, each energy consuming device (X, Y, Z, ...) is divided into one or more energy consumption groups (S21, S22, ...), and when grouping, the main energy consumption group is (S21, The energy consumption of S22...) is similar. Therefore, energy-consuming devices Z and X are energy-consuming groups S22, and energy-consuming device Y is energy-consuming group S21; confirming the load-bearing load ST3: as described above, to avoid In the present invention, when the wheeled power supply is performed, the newly activated energy consuming device is allocated to the energy consumption group to be temporarily suspended, and therefore, the host device 2 The 11 series further confirms the energy consumption group to suspend the supply, and determines the usage end demand information corresponding to each energy consuming device. If the usage end demand information of the energy consuming device is the new startup demand, the monitoring terminal 21 The host device re-adjusts the configuration of the energy-consuming group. To make the implementation step more specific, please refer to "Figure 7" for reference. The figure shows the energy-consuming group diagram of the present invention. If the newly activated energy consuming device X is disposed in the energy consumption group S21 to be temporarily suspended, the host device 211 of the monitoring terminal 21 performs the energy consuming sequential grouping step again to make the newly activated energy consuming device X Can be started normally to avoid misunderstanding of the failure of the energy-consuming device, so that the energy-consuming device X is adjusted to Adjusted to another energy-consuming group S22 to be normally supplied; the wheel-controlled supply energy ST4: According to the above, the host device 211 can further provide resource supply for each energy-consuming group according to the proposed management policy. The control, in this way, at the same time, part of the energy-consuming group is normally supplying electric energy, and the other part of the energy-consuming group is dissipated by the energy-saving management center, so that the energy dissipated therein is configured. The device cannot be activated, and the energy-saving management center adjusts the energy-consuming group of the suspended supply every certain time, so that the effect of the wheel-controlled supply is generated.

The floating adjustment energy distribution: the carrier control power supply S4 step, after the implementation of the cycle time of the present invention, the host device 211 of the monitoring terminal 21 performs the energy consumption information acquisition for each energy consumption demand terminal 22 again, Obtaining the energy consumption requirements of each energy consuming device (222, 232...), and determining whether each energy consuming device (222, 232, ...) is still active or has been stopped after a cycle time; accordingly, monitoring The end 21 system removes the energy-consuming device that has been stopped from the energy-consuming group S22, and temporarily excludes it from the energy-consuming group S22 (moves to the energy-consuming group S21), and waits for it to start again. Then, it is programmed into the energy consumption group S22; if it is a newly activated energy consuming device, it is added to the allocation of the energy consumption group S22, and the monitoring terminal 21 performs the energy dissipation configuration again according to the current situation, and makes each energy consumption The energy consumption of the group (S21 or S22) is similar. Therefore, the "dynamic floating adjustment" referred to in the present invention enables the energy-saving configuration of the overall system to conform to a better current situation, and the present invention is directed to each energy consumption. The device (222, 232...) draws energy consumption information and makes it in the system Energy situation is to accurately grasp the body, thereby providing the monitoring terminal 21 may prepare the preferred energy saving policy. Further, the present invention is referred to the "floating adjust the energy distribution." After the implementation of the steps, the "wheel-controlled energy supply" step is carried out, and the "floating adjustment energy allocation" step is performed again in one cycle to generate a cyclical management action.

Please refer to FIG. 8 , which is another embodiment of the present invention. The energy consuming devices exemplified in the above embodiments need to be activated by a user to generate an action, but nowadays energy consumption. The device is not limited thereto. For example, an air conditioner 30 separates the indoor air conditioner module 301 from the outdoor air conditioner module 302. The two modules (301, 302) are not synchronized. In the normal state, the outdoor air conditioner module 302 The operation is performed to generate the required air-conditioning gas, and the indoor air-conditioning module 301 needs to be activated by the activation of a user. Therefore, the present invention can further check the energy consumption of the normal state before the implementation. The device, such as the outdoor air conditioning module 302 shown in the figure, captures its energy consumption information and incorporates it into the allocation of the energy consumption group (such as the aforementioned S22), while the indoor air conditioning module 301 waits When the user starts, the user is added to the allocation of the energy-consuming group, and the other embodiments are the same as the above, and are not described here. Moreover, when the wheel-controlled supply is provided, the invention is in normal supply and is temporarily suspended. Number of energy consumption groups The amount can be in a specific ratio, for example, 3:1 or the like.

In summary, the system for floating energy adjustment and wheel-controlled energy supply and the method for implementing the same according to the present invention are mainly for constructing a host device, which is a host device, in a monitoring terminal (or energy-saving management center). Information is linked to one or more energy demand terminals, and at the energy demand side An energy-consuming monitoring device has one end connected to the host device and the other end is connected to each energy-consuming device, so that the monitoring terminal can effectively grasp the requirements of the energy-consuming demand end and the actual energy-consuming information; The monitoring terminal determines the energy consumption device of the current energy demand side as the "starting demand" energy consumption device, and then extracts the energy consumption information generated after the operation, to dynamically adjust the energy consuming devices according to the energy consumption thereof. Corresponding energy consumption groups, and the energy consumption of each energy consumption group is similar; in addition, the monitoring terminal (host device) performs "dynamic adjustment" on the current state of the energy consumption demand terminal every other cycle time, Confirm whether there is still an operating demand for each energy-consuming device, whether there is a newly activated energy-consuming device, etc., and then adjust the allocation of each energy-consuming group according to the above judgment; when the so-called "wheel-controlled energy supply" function is implemented, Further, the energy control group is controlled by the wheel control device to supply energy to the power consumption group, so that the group that does not need energy consumption can be in a state of suspended supply at the same time, according to which the present invention is implemented. It is indeed possible to provide a kind of "floating adjustment energy allocation" by monitoring the actual energy consumption requirements and conditions so that the overall energy consumption of all energy-consuming devices in the monitored area can be reliably grasped and analyzed by the monitoring end. And the purpose of "wheel-controlled supply of energy" to effectively improve the energy-saving function of floating adjustment energy distribution and wheel-controlled energy supply and its implementation method.
