The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for purposes of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes have not been shown in detail to avoid obscuring the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
The application provides an undervoltage release detection device, an undervoltage release detection method, an undervoltage release detection system and a computer readable storage medium, and the undervoltage release detection method, the undervoltage release detection system and the computer readable storage medium are respectively described in detail below.
First, an under-voltage release (also called an under-voltage relay) is a component including a coil and a striking pin. The mechanism is always in an unlocking state by being arranged on a traction rod of the circuit breaker mechanism, so that the energy storage cannot be ensured to be switched on. When the coil obtains enough voltage, the striking foot is attracted and retreats from the motion track of the traction rod, so that the circuit breaker can be normally opened and closed. Specifically, the under-voltage release can be applied to switch positions such as a switch. For example: the undervoltage release may be combined with the switching device and when the externally applied voltage drops, or slowly drops to a range of 70% to 35% of the rated voltage, the undervoltage relay or release combined with the switching device responds to open the device.
Referring to fig. 1, fig. 1 is a schematic diagram of an under-voltage tripper detection system provided in an embodiment of the present application, where the under-voltage tripper detection system may include a terminal device 100, an under-voltage tripper 200, a power supply device 300, and a signal transmission device 400, where the terminal device 100 may transmit first data to the transmission device 400 and control the power supply device 300 to supply power to the under-voltage tripper 200, so as to execute an under-voltage tripper detection scheme in the present application.
The specific working principle comprises: and if the under-voltage release is a qualified product or has normal functions, the under-voltage release receives different voltages and can perform corresponding feedback actions. For example: when receiving the voltage which can make the coil of the under-voltage release to be attracted, the coil of the under-voltage release can be attracted. Otherwise, if the under-voltage release receives a voltage which can not enable the coil of the under-voltage release to attract, the coil of the under-voltage release is reset. Based on the above, the essence of the application is that whether the under-voltage release is qualified can be determined by providing corresponding voltage and detecting whether the coil is attracted or not. In this embodiment of the present application, the terminal device may be any device having a computing function. The power supply device may be any power supply capable of supplying power by generating different voltage values, for example, a power supply provided with a voltage regulator and a voltage regulator. Meanwhile, the terminal device can be any device which is provided with pulse signals and electric signals. The signal transmission device 400 may be connected to the terminal device through a serial port, for example, the serial port may be an RS-232 standard interface. After a closed path is formed inside the signal transmission device, the TX port and the RX port of the RS-232 interface are communicated, so that the terminal equipment can receive the data input into the closed path.
In the embodiment of the present application, the terminal device 100 includes, but is not limited to, a desktop computer, a portable computer, a network server, a palm computer (Personal Digital Assistant, PDA), a tablet computer, a wireless terminal device, an embedded device, a mobile phone, or the like.
It should be noted that, the schematic diagram of the under-voltage tripper detection system shown in fig. 1 is only an example, and the under-voltage tripper detection system and the scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation to the technical solution provided in the embodiments of the present application, and as a person of ordinary skill in the art can know that, with the evolution of the under-voltage tripper detection system and the appearance of a new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.
Based on the foregoing, fig. 2 is a schematic flow chart of an embodiment of a method for detecting an under-voltage tripper in an embodiment of the application. The undervoltage release detection method comprises the following steps:
201. the terminal equipment controls the power supply device to supply power to the under-voltage tripper to be tested.
In one possible implementation manner, after the terminal device receives the start signal, the power supply device may be controlled to supply power to the under-voltage tripper to be tested. Wherein the activation signal may be activated by an associated worker, for example: the staff can run the relevant detection program loaded on the terminal equipment, and can issue relevant control instructions to the terminal equipment after the detection program is successfully run. Alternatively, the activation signal may be triggered in other manners, which are not limited in this application.
202. If the voltage of the power supply device for supplying power to the under-voltage release to be tested meets a first threshold value, the under-voltage release to be tested is closed by power receiving, a closed channel is formed in the signal transmission device, the terminal equipment sends first data to the signal transmission device, and the first data returns to the terminal equipment through the closed channel.
In this embodiment of the present application, the signal transmission device may include an induction device, where the induction device may be used to sense whether the coil inside the undervoltage tripper to be tested can be normally engaged or disengaged. When the induction device induces the attraction of the internal coil, the induction device can control a preset circuit in the signal transmission device to be closed so as to form a closed path.
After receiving the starting signal, the terminal equipment can send first data for detecting whether the undervoltage release to be tested is qualified or not to the signal transmission device. Meanwhile, the terminal equipment can also control the power supply device to supply power to the under-voltage tripper to be tested, and if the under-voltage tripper to be tested is in a normal state, the under-voltage tripper to be tested can respond to the voltage of the power supply device and make corresponding action feedback. For example: when the under-voltage release to be tested receives a voltage value of 85% Ue, if the under-voltage release to be tested is normal, the normal or qualified under-voltage release to be tested can be caused to drive the connected signal transmission device to form a closed path.
203. The terminal equipment determines that the received second data is identical to the first data, and determines that the undervoltage release to be tested is qualified, wherein the second data is the data received by the first data through the closed path.
After the terminal equipment outputs the first data to the signal transmission device, if the under-voltage release to be tested is normal, the signal transmission device forms a closed path, so that the position of the first data input is actually input with a closed path, and the first data is returned to the terminal equipment through the closed path, namely the second data received by the terminal equipment is the first data sent by the terminal equipment. Therefore, after the terminal equipment detects the second data, the undervoltage release to be detected can be determined to be a qualified product.
Since the terminal device can continuously send the first signal to the signal transmission device, after the power supply device supplies power according to the voltage of the first threshold value, a channel is formed inside the signal transmission device, so that the first signal passes through the inside of the signal transmission device, and the terminal device receives the second data.
In addition, the input first data and the received second data in the embodiments of the present application may be regarded as the same signal, and the reason that the descriptions using different terms specifically use is that after the first data is input, when there is a certain signal attenuation in the path of the first data, a certain error exists between the finally received second data and the original first data, or a certain loss exists. Therefore, when the error or loss is eliminated, the two are the same. Meanwhile, another reason for describing the returned first data with the second data is that the state of the current data, i.e., the first data is the input data, can be distinguished, and the second data is the returned data.
According to the undervoltage release detection method, through supplying power to the undervoltage release, if the undervoltage release can normally work, the signal transmission device can form a closed loop. Therefore, if the terminal device inputs the first data to the under-voltage release, the terminal device can detect the same second data returned through the closed loop. If the second data can be received, whether the under-voltage release can work normally is determined, whether the under-voltage release is qualified is further determined, whether the under-voltage release is qualified is avoided from being detected manually, and labor cost is reduced.
In an embodiment of the present application, the terminal device controls the power supply device to supply power to the under-voltage tripper to be tested, including:
the terminal equipment controls the power supply device to supply power to the under-voltage release to be tested according to preset time.
When the terminal equipment controls the power supply device to supply power, the power supply device can be controlled to continuously supply power to the under-voltage release to be tested according to a certain time, so that the under-voltage release to be tested has enough time to respond to a voltage value so as to make feedback. For example: the time for which power is continuously supplied may be 5 seconds, 10 seconds, etc. Therefore, the terminal device cannot immediately receive the second data because of the possible response time of the under-voltage release to be tested. Therefore, a time threshold, for example 20 seconds, may be set. And when the terminal equipment does not receive the second data within the time threshold, determining that the undervoltage release to be tested is an unqualified product. In the embodiment of the present application, the power supply time and the time threshold may be set according to actual situations, which is not limited herein.
In an embodiment of the present application, after the terminal device controls the power supply device to supply power to the under-voltage tripper to be tested, the method further includes:
if the voltage of the power supply device for supplying power to the under-voltage tripper to be tested meets a second threshold value, the power receiving of the under-voltage tripper to be tested is disconnected, a closed circuit breaker is formed in the signal transmission device, and the terminal equipment sends first data to the signal transmission device; if the terminal equipment does not receive the data within the preset time, determining that the under-voltage release to be tested is qualified.
According to the above embodiment, the power supply device may be a power supply device that supplies power according to different voltage values. In order to further detect whether the under-voltage tripper to be tested can work normally, the coil of the under-voltage tripper to be tested needs to be capable of being attracted under the voltage of a first threshold value and disconnected under the voltage of a second threshold value. The specific reason is that if the under-voltage tripper to be tested can only be attracted, but cannot be disconnected at other voltage values, namely reset, the under-voltage tripper to be tested is still an unqualified under-voltage tripper at the moment. Therefore, the two ways of power supply have the advantages that if the same second data can be received under the voltage of the first threshold value, the undervoltage tripper to be tested can be determined to make a correct actuation action, namely, the undervoltage tripper to be tested can make corresponding feedback under the corresponding high voltage; if no data is received under the voltage of the second threshold value, the coil in the under-voltage release to be tested can be determined to be capable of resetting, so that the channel of the signal transmission device is disconnected, namely the coil in the under-voltage release to be tested can be reset under the corresponding low voltage value.
It should be noted that, at the voltage of the second threshold, when the terminal device may still receive data after going to the signal transmission device, there may be a case where the received data is not identical to the first data. This occurs because if the under-voltage trip to be tested receives a voltage at the second threshold, it should be opened if the trip is acceptable. At this time, there may be a bad contact inside the signal transmission device, where the signal transmission device is turned on in half of the time and turned off in half of the time, so that the data returned by the signal transmission device after receiving the first data is intermittent. The intermittent data is not identical to the first data. Therefore, at the voltage of the second threshold, any data cannot be received, so that the trip device can be ensured to perform the action matched with the voltage of the second threshold, and no other accidents exist. Therefore, if the terminal device receives the third data which is not the same as the first data under the second threshold voltage, the terminal device can send out prompt information to inform corresponding staff to prompt the corresponding staff to detect the undervoltage tripper detection system so as to eliminate abnormal conditions. Specifically, the terminal system may send a prompt message to a preset phone or mailbox address, or display a corresponding prompt message on a display device of the terminal device, which is not limited herein. In addition, it should be noted that, in the embodiment of the present application, the voltage of the second threshold may be between 45% ue and 60% ue, or may be other possible values, which is not limited in the present application.
Therefore, when the voltage changes, the terminal equipment can not receive any data, and the under-voltage tripper to be tested can be proved to perform different correct actions according to different voltages, so that the under-voltage tripper to be tested can be further proved to be qualified (or called normal).
In an embodiment of the present application, the determining, by the terminal device, that the received second data is the same as the first data, and determining that the under-voltage release is closed includes:
the terminal equipment determines that the received second data is identical to the first data, and records a first moment when the power supply device starts to supply power and a second moment when the second data is received; the terminal equipment determines the time difference between the first time and the second time according to the first time and the second time; if the time difference meets a preset time difference threshold, determining that the under-voltage release to be tested is qualified. And if the time difference does not meet the time difference threshold, determining that the under-voltage release to be tested is unqualified.
In practice, the under-voltage release needs to react immediately after receiving the voltage value that pulls the coil in. For example: in the circuit, if the response time of the under-voltage release to conduct coil attraction or release is long in response to the voltage value, unexpected problems are easy to occur. For example: if the undervoltage release in the circuit cannot be immediately disconnected, the electrical equipment in the circuit is easily damaged by the excessive voltage. Therefore, in order to further improve the accuracy of detecting whether the undervoltage tripper to be detected is qualified or not, when the power supply device starts to supply power, the power supply time when the power supply device starts to supply power, namely, the first time, can be recorded. Because the terminal equipment synchronously inputs the first data to the under-voltage release to be tested, after a closed path is formed in the signal transmission device, the terminal equipment can acquire the second data, and the acquisition time of acquiring the second data, namely the second time, is recorded. In this embodiment of the present application, the time difference between the first time and the second time may be actually understood as the response time of the feedback action after the under-voltage tripper to be tested receives the voltage. When the response time is shorter, the response sensitivity of the under-voltage release to be tested is higher, and the response sensitivity is higher. Specifically, when the time difference is shorter, the under-voltage tripper to be tested is in a good state, and when the time difference is longer, the under-voltage tripper to be tested is in a bad state. When the under-voltage release to be tested is in a good state, the under-voltage release to be tested can be determined to be qualified, and when the under-voltage release to be tested is in a bad state, the under-voltage release to be tested can be determined to be unqualified.
When feedback second data is not detected within a certain period of time, it is proved that a channel is not formed in the signal transmission device, and it is further proved that the under-voltage tripper to be tested cannot be attracted smoothly, at the moment, the second moment is not required to be recorded, it can be directly determined that the under-voltage tripper to be tested cannot perform correct action feedback according to preset voltage, and therefore the under-voltage tripper to be tested is unqualified.
In order to simplify the judging process, the method can be directly used for judging whether the under-voltage release to be tested is qualified or not by setting a time difference threshold value. For example: the time difference threshold may be 0.5 seconds, 1 second, etc., and is not particularly limited herein.
In an embodiment of the present application, the signal transmission device includes micro-gap switch and metal pole, if power supply unit is to the voltage of awaiting measuring undervoltage release power supply satisfy first threshold value for the power reception closure of awaiting measuring undervoltage release, and then makes signal transmission device inside form closed passageway, includes: if the voltage of the power supply device for supplying power to the under-voltage tripper to be tested meets a first threshold value, a coil in the under-voltage tripper to be tested is attracted, a metal rod connected with the coil is driven to touch the micro switch, and the micro switch forms a closed path.
In this embodiment, as shown in fig. 3, the signal transmission device may include a micro switch and a metal patch or a metal rod, where the micro switch may include three interfaces, interface 1, interface 2, and interface 3. The interface 3 is arranged adjacent to the under-voltage release to be tested through the metal patch, and when the coil in the under-voltage release to be tested is electrified and then is attracted, the metal patch can be pushed to be attached to the interface 3, so that the micro switch is closed, and a passage is formed. The under-voltage release to be tested can further comprise an interface 4 and an interface 5 which are connected with the power supply device, so that the power supply device supplies power to the under-voltage release to be tested through the interface 4 and the interface 5, and the interface 1 and the interface 2 are connected with the terminal equipment. According to the structure shown in fig. 3, if the power supply device supplies power to the under-voltage tripper to be tested according to the voltage of the first threshold, if the under-voltage tripper to be tested is a qualified product, the metal patch is attached to the micro switch, so that the micro switch is turned on to form a closed path. Otherwise, if the under-voltage release to be tested is an unqualified product, the metal patch is not attached to the micro-switch, and the inside of the micro-switch is not conducted. In this process, the terminal device may send the first data to the micro switch through the interface 1 or the interface 2 all the time, if the micro switch is turned on, the terminal device will receive the second data from the interface 2 if the terminal device sends the first data through the interface 1, and if the terminal device sends the first data through the interface 2, the terminal device will receive the second data from the interface 1, so as to determine whether the under-voltage release to be tested is normal. Meanwhile, the interface 4 and the interface 5 may be connected with a voltage regulating circuit, and it should be noted that the structure of the under-voltage release to be tested is not completely shown, and fig. 3 only shows a part of the structure of the under-voltage release to be tested.
In an embodiment of the present application, the detection system further includes a serial port; the terminal equipment is connected with the signal transmission device through a serial port. Specifically, the connection manner of the serial port, the terminal device and the signal transmission device is shown in fig. 4.
In one embodiment of the present application, the signal transmission device includes any one of a signal detector and a sensor.
In order to meet different practical conditions, different modes can be adopted to detect whether the under-voltage release to be detected is qualified or not. For example: when adopting the structure of signal detector and metal pole, can make terminal equipment wait to survey undervoltage release simultaneously and supply power for whether the coil of undervoltage release that awaits measuring is actuation or release, the signal detector of this application can be a signal detector including touch switch, and the metal pole can set up in the position relative with this touch switch, makes the metal pole remove the back and can touch this touch switch. When the coil of the undervoltage release to be tested is attracted, the metal rod touches the touch switch of the signal detector, so that the signal detector starts to work. When the coil of the undervoltage release to be tested is reset, the metal rod leaves the touch switch of the signal detector, so that the signal detector stops working.
Because the metal rod and the signal detector belong to the signal transmission device, when the metal rod is contacted with the signal detector, the inside of the signal transmission device is also in an internal conduction state. At this time, when the terminal device inputs the first data to the signal detector again, the signal detector can receive the first data due to the start of operation. If the signal detector is in a stop state, the first data cannot be received. The signal detector may detect the first data at this time and generate a second data identical to the first data to be returned to the terminal device. When the terminal equipment can receive the second data, the under-voltage release to be tested can be determined to be the qualified under-voltage release capable of working normally. Compared with the micro switch, the signal detector has the advantages that the signal detector generates second data which are the same as the first data, so that the loss of the first data caused by the micro switch can be avoided, and if the error is overlarge, the second data judged by the terminal equipment are different from the first data, so that a result of judging that the undervoltage release is unqualified is caused.
And if the voltage which enables the under-voltage release to be tested to be disconnected is adopted for power supply, the release is reset, the metal rod is driven to stop touching the signal detector, and the signal detector stops working. At this time, when the terminal device inputs the first data to the signal detector again, the signal detector does not return the same second data based on the input first data.
Alternatively, when a conductive sensor is used, the conductive sensor is slightly different from the signal detector and the micro switch. The specific difference is that the sensor can still detect whether the coil of the undervoltage release to be detected is attracted or released by sensing whether the metal rod is touched or not. When the sensor detects that the metal rod touches the sensor, a touch signal of the metal rod touching the sensor can be directly sent. At this time, if the terminal device detects the touch signal, it can determine whether the under-voltage release to be tested is a qualified under-voltage release capable of working normally according to whether the terminal device controls the control signal of the power supply device to supply power to the under-voltage release to be tested. For example: if the terminal equipment controls the power supply device to supply power to the undervoltage tripper to be tested according to the voltage of the first threshold value, and simultaneously receives a touch signal fed back by the sensor under the condition, the undervoltage tripper to be tested is determined to be qualified; if the terminal equipment controls the power supply device to supply power to the undervoltage release to be tested according to other voltages at the moment and receives the touch signal fed back by the sensor, the correct action of the undervoltage release which is not made through normal voltage feedback can be determined. At this time, the terminal device may display a prompt message to prompt the relevant staff to pay attention to the problem, so that the staff can check whether the problem occurs on the metal rod. Comprising the following steps: the terminal device may display on its own display means: please see if the metal rod is problematic in the word to prompt.
