With the diversified development of industrial types, many electromechanical devices for industrial or commercial use often need a specific detection system for detection, so as to avoid the electromechanical devices from generating abnormalities to affect the industrial and commercial operations.
Generally speaking, the detection system stores an upper limit value and a lower limit value corresponding to the detection item, and when the detection value of the detection item exceeds the upper limit value or the lower limit value, the detection system generates an alarm signal and transmits the alarm signal to a monitoring end. And items detected usually include vibration, temperature, voltage, current.
However, in consideration of various factors, the monitoring end does not correspond to only one electromechanical device, and usually corresponds to a plurality of electromechanical devices in the surrounding area of the monitoring end. Therefore, when the monitoring end receives the alarm signal, a far-end maintenance person at the monitoring end may go to the electromechanical device generating the alarm signal for maintenance, or the monitoring person at the monitoring end may notify a near-end maintenance person near the electromechanical device generating the alarm signal, and then the near-end maintenance person goes to the electromechanical device for maintenance. When the maintenance personnel do not arrive at the site, the electromechanical device generating the alarm signal is still in continuous operation, which may cause damage to the electromechanical device and even may cause danger to surrounding personnel. The monitoring personnel at the monitoring end can not directly maintain the electromechanical device in a remote control mode.
In addition, the detection system can only generate an alarm signal when the detection value exceeds the upper limit value or the lower limit value, and even if the detection value suddenly rises or falls, no action is generated. Therefore, the warning signal can only be remedied afterwards, and the danger that may occur cannot be prevented in advance.

Detailed Description
The invention is described in detail below with reference to the drawings and specific examples, but the invention is not limited thereto.
Referring to fig. 1A and fig. 1B together, wherein fig. 1A and fig. 1B are block schematic diagrams illustrating an automatic sudden change detection and warning system according to a preferred embodiment of the present invention, and a circle a in fig. 1A is connected to a circle a in fig. 1B, and a circle B in fig. 1A is connected to a circle B in fig. 1B. As shown in the figure, an automatic sudden change detection and alarm system 100 comprises a detection module 1, a detection data collection and storage module 2, a sudden change judgment and alarm module 3 and a mobile communication device 5.
The sudden change automatic detection alarm system 100 is used for automatically sending out a sudden change alarm signal when detecting that a sudden change event occurs in an electromechanical device arranged in a working area. In the present embodiment, three electromechanical devices 200a, 200b, and 200c are drawn as an illustration, and the electromechanical devices 200a, 200b, and 200c are respectively disposed in the work areas WA1, WA2, and WA3, but not limited thereto. In other embodiments of the present invention, the number of electromechanical devices may be one or other.
The detection module 1 is disposed at the electromechanical devices 200a, 200b, and 200c, and is configured to detect the electromechanical devices 200a, 200b, and 200c to obtain a plurality of detection data 221 arranged according to a detection timing sequence. The detection module 1 includes a detection kit 11 and an analog-to-digital converter 12. The detection kit 11 includes at least one of a vibration gauge 111, a temperature detector 112, a voltage detector 113 and a current detector 114. In the present embodiment, the detection kit 11 includes the vibration gauge 111, the temperature detector 112, the voltage detector 113 and the current detector 114, and therefore the detection data 221 includes a vibration amount, a temperature value, a voltage value and a current value. The analog-to-digital converter 12 is electrically connected to the detection kit 11, so as to convert the detection data into a digital signal and transmit the digital signal to the detection data collection and storage module 2 for storage.
And the detection data collection and storage module 2 is in communication connection with the detection module 1 to collect and store the detection data. The inspection data collection storage module 2 includes an inspection data collection interface 21 and a storage unit 22. The inspection data collection interface 21 is communicatively connected to the inspection module 1 for collecting the inspection data 221. The storage unit 22 is electrically connected to the inspection data collection interface 21, and is used to store the inspection data 221, and may be a Memory, a Flash Memory (Flash Memory), a storage chip, a register, or a device capable of storing the inspection data.
The abrupt change judgment and alarm module 3, electrically connected to the detected data collection and storage module 2, comprises a data sampling unit 31, an abrupt change judgment unit 32 and an alarm communication unit 33. The detection data collection and storage module 2 and the sudden change judgment module 3 can be modularly arranged on a gateway.
The data sampling unit 31 records a set sampling determination quantity 311, and sequentially retrieves the detection data 221 of the set sampling determination quantity from the detection data 221 according to the detection timing to serve as a sequentially sampled detection data group. The sudden change judging unit 32 is electrically connected to the data sampling unit 31, and is configured with a sudden change judging condition 321, and analyzes a set of instantaneous change rate data according to the sequential sampling detection data group, and sends out a sudden change warning signal when judging that the instantaneous change rate data satisfies the sudden change judging condition 321. The sudden change determination unit 32 is a chip analyzed by an algorithm. The alarm communication unit 33 is electrically connected to the sudden change determination unit 32, and is configured to send a sudden change alarm signal to the mobile communication device 5.
The number of the detection data 221 is larger than or equal to the sampling judgment number, so that the data sampling unit 31 can capture the detection data 221 with the sampling judgment number, and the detection data 221 with the sampling judgment number is defined as a sequential sampling detection data group. Preferably, the number of the detection data 221 is equal to the sampling determination number, which means that the data sampling unit 31 is capable of capturing the sampling determination number of the detection data 221 in real time.
It should be noted that the data sampling unit 31 sequentially retrieves the detection data 221 according to the detection timing, so as to confirm that the instantaneous slew rate data is analyzed. If the data sampling unit 31 does not sequentially capture the detection data 221 within the detection timing sequence, the sudden change determination unit 32 cannot determine the instantaneous change rate data. For example, the data sampling unit 31 may sequentially capture the first second, the second and the third second detection data 221, or sequentially capture the first second, the third second and the fifth second detection data 221. However, the data sampling unit 31 may not randomly capture the first second, fifth second and second detection data 221.
The snap-out condition 321 is generally determined by the amount of trend, slope, percentage, and instantaneous slew rate data achieved. For example, the detected data 221 is the temperature in celsius of the electromechanical device 200a, and the sudden change determination condition 321 is that any instantaneous change rate data exceeding plus or minus 5% is satisfied, and a sudden change warning signal is sent.
As shown in the above table, the temperature suddenly rises from 51 degrees to 57 degrees in the second to third seconds, the instantaneous change rate data is 11.76% and exceeds positive 5% in the sudden change determination condition 321, which indicates that the detection data 221 of the electromechanical device 200a suddenly changes, and in this case, suddenly rises. The sudden change determination unit 32 determines that the electromechanical device 200a has a sudden change event and sends a sudden change alarm signal. Therefore, the invention has the effect of preventing the electromechanical device from generating abnormity in advance. The electromechanical device 200a may be a water pump and a sudden temperature rise may indicate that water has been drained and that the water pump is pumping sand, soil, stones, etc.
The sensed data 221 may also be voltage, current, or vibration, which may indicate a problem with a power system supplying power to the electromechanical device when the voltage is suddenly changed. When the current suddenly changes, it may indicate that the coil and the insulator inside the electromechanical device are damaged. The vibration quantity can detect whether the electromechanical device is not centered, the severity of vibration, unbalance, foundation deformation, soft feet and the like. The instantaneous change rate data can be percentage or numerical value, and usually, the current, the voltage and the temperature adopt percentage, and the vibration quantity adopts numerical value.
In other embodiments of the present invention, the detection data 221 may also be compared with each of the sequentially sampled detection data groups, taking the above table as an example, the detection data 221 of the 5 th second may be sequentially compared with the 1 st second, the 2 nd second, the 3 rd second and the 4 th second to analyze the instantaneous change rate data, when any one of the instantaneous change rate data exceeds plus or minus 5%, the detection data 221 of the electromechanical device 200a is suddenly changed, which is more sensitive in judgment conditions and can completely achieve the prevention effect. In addition, the transient variation rate data of any two or more of them may exceed plus or minus 5%, indicating that the detected data 221 of the electromechanical device 200a suddenly varies. This further ensures that the electromechanical device 200a is substantially abrupt, not because of any factor that does not affect the electromechanical device. In practice, the sequentially sampled detection data group can be sampled to 60 seconds of detection data 221 at most.
The mobile communication device 5 is communicatively connected to the sudden change judgment warning module 3 and the electromechanical devices 200a, 200b, and 200c, is carried by a mobile maintenance personnel for receiving sudden change warning signals, and includes a positioning module 51, a control module 52, and a wireless communication module 54. The control module 52 further includes a position determination unit 521 and a touch display unit 522.
The positioning module 51 records a work area zone coordinate 511 of the work areas WA1, WA2, WA3 for positioning the mobile communication device 5 to obtain a communication device position coordinate 512. In the present embodiment, work area section coordinates 511 include work area section coordinates of work area WA1, work area section coordinates of work area WA2, and work area section coordinates of work area WA 3.
The position determining unit 521 is electrically connected to the positioning module 51 and configured to determine whether the position coordinate 512 of the communication device is outside the working area interval coordinate 511.
The touch display unit 522 displays a map data 5221, the map data 5221 displays area images WAC1, WAC2, and WAC3 (shown in fig. 2) of the working area interval coordinates 511 and a coordinate point image ME (shown in fig. 2) of the communication device position coordinates 512, and displays an operation interface 5222 of the electromechanical device generating the snap event when the mobile maintenance personnel touches the area image (WAC1) corresponding to the electromechanical device generating the snap event (such as the electromechanical device 200a in the embodiment), so that the mobile maintenance personnel can operate the electromechanical device to transmit an operation signal.
In the present embodiment, the electromechanical devices 200a, 200b, and 200c are electrically connected to an operation signal transceiving interface 300. The wireless communication module 54 is electrically connected to the touch display unit 522, so as to transmit the control signal to the electromechanical device (such as the electromechanical device 200a in the present embodiment) having the sudden change event through the operation signal transceiving interface 300.
Referring to fig. 1A to fig. 3, fig. 2 is a schematic diagram illustrating a position determination unit of a control module of a mobile communication device of an automatic sudden change detection alarm system according to a preferred embodiment of the present invention; FIG. 3 is a schematic diagram of a touch display unit of a control module of a mobile communication device of an automatic sudden change detection and warning system according to a preferred embodiment of the invention.
As shown, when mobile communication device 5 receives the sudden change alert signal, position determination unit 521 determines whether communication device position coordinates 512 are outside of the workspace coordinates 511. In the present embodiment, the communication device position coordinates 512 are located in the coordinate point image ME outside the work area section coordinates 511.
Therefore, the touch display unit 522 of the control module 52 displays a map data 5221, and the area images WAC1, WAC2, and WAC3 of the work area section coordinates 511 and the coordinate point image ME of the communication device position coordinates 512 are displayed on the map data 5221. When the mechanic selects the area image WAC1, the operation interface 5222 of the electromechanical device 200a with the sudden change event is displayed for the mechanic to operate to transmit the operation signal, so as to directly and remotely control the electromechanical device 200a with the sudden change event, thereby achieving the effect of remotely and immediately controlling the electromechanical device with the sudden change event.
Generally, the control signal is transmitted to the gateway, and the gateway transmits the control signal to a controller (usually a PLC) of the electromechanical device, so as to control the electromechanical device.
In summary, the automatic sudden change detection and alarm system provided by the present invention can generate a sudden change alarm signal when the electromechanical device has a sudden change, and remotely control the electromechanical device having a sudden change event by the mobile communication device.
Compared with the prior art, the electromechanical device needs to reach the upper limit value and the lower limit value, the detection system can send out the alarm signal, and the monitoring end can not directly control the electromechanical device by the remote end.
The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the scope of the claims.
