To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Embodiments of the present application are set forth in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.

As mentioned in the background art, in the prior art, remote signaling monitoring has a problem that feedback of abnormal operation of equipment is not timely, and the inventor finds that the problem is caused by high defect rate of an optical coupler and easy damage. When the optical coupling insert is damaged, the open channel fails, especially when important signal monitoring points of certain important unit positions are involved, such as SF6 leakage, low pressure of a switch air chamber and the like, of the power grid equipment are not monitored. If the optical coupling plug-in is damaged, the running state of the power grid equipment cannot be detected, and abnormal equipment running is not fed back timely.
For the above reasons, the present invention provides a remote signaling open-in self-detection system, a control method, a control device, and a storage medium.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a remote signaling open-in self-test system according to an embodiment. In one embodiment, as shown in fig. 1, there is provided a remote signaling open-in self-test system comprising: n open paths, n opto-coupler detection switches 110 and a controller 120. Wherein n is a natural number of 1 or more.
The open path is provided with an open optical coupler 130. The one end electricity of opto-coupler detection switch 110 is connected first power 140, the other end correspondence of opto-coupler detection switch 110 with one open the input electricity of opto-coupler 130 and be connected, n opto-coupler detection switch 110 is used for being in the closure state when carrying out self-checking. The controller 120 is electrically connected to an output end of the incoupling optical coupler 130, and is configured to detect whether the incoupling optical coupler 130 corresponding to the optical coupler detection switch 110 is normal after the optical coupler detection switch 110 is in a closed state.
The open channel is a channel for transmitting a status signal of the corresponding operating device, and particularly transmits an abnormal signal of the corresponding operating device. Generally, if the operating device corresponding to the open channel is abnormal, an abnormal signal is transmitted to the controller 120 through the open channel, so that the controller 120 prompts an operation and maintenance worker to perform maintenance according to the abnormal signal. The incoupling coupler 130 is a device for transmitting an electrical signal through light, and generally encapsulates a light emitter (infrared light emitting diode LED) and a light receiver (photosensitive semiconductor, photosensitive resistor) in the same package. The first power source 140 may be positive (e.g., +5V) or negative (e.g., -5V), and the embodiment is not limited thereto.
Specifically, when it is necessary to detect the incoupling optical coupler 130, the optical coupler detection switch 110 is closed, so that the optical coupler detection switch 110 is in a closed state, at this time, the voltage of the first power supply 140 is provided to the incoupling optical coupler 130, and if the incoupling optical coupler 130 is normally opened, the controller 120 may receive a detection signal (for example, a low level signal), so that the controller 120 is configured to determine that the incoupling optical coupler 130 is normal when the optical coupler detection switch 110 receives a detection signal sent by the incoupling optical coupler 130 after being in the closed state. Wherein the detection signal open optocoupler 130 is generated when turned on. If the controller 120 is after the optical coupling detection switch 110 is closed, when the controller 120 cannot receive a detection signal sent by the incoupling optical coupler 130 corresponding to the optical coupling detection switch 110, the corresponding incoupling optical coupler 130 may be damaged, or the optical coupling detection switch 110 may be abnormally and normally closed, so that when the controller 120 cannot receive a detection signal sent by the incoupling optical coupler 130 corresponding to the optical coupling detection switch 110, it is determined that the optical coupling detection switch 110 is abnormal and/or the incoupling optical coupler 130 corresponding to the optical coupling detection switch 110 is abnormal.
For example, when the first incoupling optical coupler 130 of the first open channel needs to be detected, the first optical coupler detection switch 110 is turned off. At this time, if the controller 120 can receive the detection signal transmitted from the first incoupling coupler 130, it is determined that the first incoupling coupler 130 is normal. If the controller 120 cannot receive a detection signal sent by the first incoupling optical coupler 130, it is determined that the first incoupling optical coupler 130 or the first optical coupler detection switch 110 is abnormal, and an abnormal prompt message can be sent to remind operation and maintenance personnel to troubleshoot problems.
In this embodiment, it detects to set up opto-coupler detection switch 110 through opening at every and go into the route, when needs carry out the self-checking, then closed opto-coupler detection switch 110, whether the controller 120 detects out the corresponding opto-coupler 130 of opening according to whether can receive the detected signal and unusual, if open opto-coupler 130 unusual can in time learn, consequently can in time investigate equipment running state and change new opto-coupler when opening opto-coupler 130 unusual, avoided because the opto-coupler harm leads to the unable normal detection of equipment defect to go out, the promptness of the unusual feedback of equipment operation has been improved.
It should be noted that each open optical coupler 130 may correspond to a separate controller 120, or n open optical couplers 130 may correspond to a controller 120, so as to reduce the system composition and the system cost.
Referring to fig. 2, fig. 2 is a schematic diagram of an embodiment of a controller 120 receiving a detection signal. As shown in fig. 2, the open optical coupler 130 includes a light emitting diode 131, a phototransistor 132, and a driving source 133 (e.g., +5V), wherein a control terminal of the phototransistor 132 is disposed opposite to the light emitting diode 131, an anode of the light emitting diode 131 is electrically connected to the first power source 140, and a cathode of the light emitting diode 131 is grounded. The first terminal of the phototriode is electrically connected to the input terminal of the controller 120 and the excitation source 133, respectively, and the second terminal of the phototriode 132 is grounded. When the optocoupler detection switch 110 is turned on, the voltage (for example +24V) of the first power source 140 causes the light emitting diode 131 to emit light, and when the light emitting diode 131 emits light, the phototriode 132 is turned on (that is, the on-optocoupler 130 is turned on), and at this time, the controller 120 may receive a low level signal, that is, a detection signal is received, which indicates that the on-optocoupler 130 is normal. When the optocoupler detection switch 110 is turned on, if the controller 120 receives a high level signal, it indicates that the phototransistor 132 is not turned on (i.e., the optocoupler 130 is turned off), and indicates that the optocoupler 130 is abnormal or the optocoupler detection switch 110 is not normally turned on.
Referring to fig. 3, fig. 3 is a schematic structural diagram of another remote-controlled self-test system according to an embodiment. In one embodiment, as shown in FIG. 3, each open path includes an open switch 150 associated with the operational equipment.
The first end of the switch 150 is electrically connected to the second power supply 160, the second end of the switch 150 is electrically connected to the input end of the corresponding switch coupler 130, the switch 150 is configured to be in a closed state when the corresponding running device runs abnormally, and transmit the electrical signal of the second power supply 160 to the corresponding switch coupler 130, so that the switch coupler 130 generates an abnormal signal according to the electrical signal of the second power supply 160 and transmits the abnormal signal to the controller 120.
Specifically, when the operation device is abnormal, the on-switch 150 is closed, and an electrical signal of the second power source 160 is transmitted to the on-optocoupler 130, so that the on-optocoupler 130 is turned on, thereby sending an abnormal signal (e.g., a low level signal) to the controller 120. However, if the open optical coupler 130 is damaged, even if the open switch 150 is closed, the controller 120 receives a normal signal (for example, a high level signal), and at this time, the operation state of the operating device cannot be normally monitored, and the feedback cannot be performed in time when the operating device is abnormal.
It should be noted that one open switch 150 corresponds to one operating device, but one operating device may correspond to more than one open switch 150. It is understood that one operation device may have a plurality of monitoring items, one monitoring item corresponds to one open path, and the open switch 150 of each open path corresponds to one monitoring item, for example, SF6 leakage, switch chamber pressure, etc. may be monitored. Alternatively, the first power source 140 and the second power source 160 may be the same power source or different power sources. Preferably, the first power supply 140 and the second power supply 160 are the same power supply in order to reduce the components of the system.
In one embodiment, the remote signaling open self-test system further includes an open block switch 170. A first terminal of the on/off switch 170 is electrically connected to the second power supply 160, a second terminal of the on/off switch 170 is connected to a first terminal of the on/off switch 150, and the on/off switch 170 is configured to be in an off state before detecting whether the on/off optocoupler 130 is normal, so as to block signals transmitted through the on/off switch 150.
Specifically, the open/close switch 170 is configured to be in an off state to close the signal transmitted through the open switch 150 when detecting the open optical coupler 130. If the opto-coupler detection switch 110 is abnormally not normally closed, the controller 120 should not receive the detection signal at this time. However, at this time, if the open switch 150 corresponding to the open optical coupler 130 is just closed, the controller 120 may also receive a low level signal, and the controller 120 may consider that the optical coupler detection switch 110 and the open optical coupler 130 are both normal, which may cause a detection hidden danger, resulting in an inaccurate detection result.
In this embodiment, the detection of the incoming optical coupler 130 is performed after the incoming partition switch 170 is turned off, so that a problem that the detection result is not accurate enough due to the fact that the incoming switch 150 corresponding to the incoming optical coupler 130 is just turned on in the detection process of the incoming optical coupler 130 is solved, and the detection accuracy of the remote signaling incoming self-detection system is improved. When the first power source 140 and the second power source 160 are the same power source, the first terminal of the on/off switch 170 is electrically connected to the first terminal of the photo-coupler detection switch 110.
In one embodiment, the remote signaling open self-detection system further comprises a blocking detection optocoupler 180. An input end of the cut-off detection optocoupler 180 is electrically connected with a second end of the cut-in cut-off switch 170, an output end of the cut-off detection optocoupler 180 is electrically connected with the controller 120, and the cut-off detection optocoupler 180 is used for confirming that a signal transmitted by the cut-in switch 150 is cut off.
Specifically, in the routine monitoring work of the opening passage, the opening blocking switch 170 is in a closed state. When the incoupling optical coupler 130 needs to be detected, the incoupling blocking switch 170 is turned off to block the signal transmitted through the incoupling switch 150. The working principle of the blocking detection optocoupler 180 can refer to the working principle of the open-in optocoupler 130 in any of the above embodiments, and details are not described in this embodiment. When the on-off switch 170 is in the off state, the controller 120 may receive a low level signal from the off detection optocoupler 180. If the on/off switch 170 is off, the controller 120 may receive a high level signal from the off detection optocoupler 180. The controller 120 can confirm whether the signal transmitted by the switch-on switch 150 is cut off according to the signal sent by the cut-off detection optocoupler 180. Optionally, the controller 120 is further configured to determine that the signal transmitted by the open switch 150 is blocked when receiving a confirmation signal sent by the blocking detection optocoupler 180; the optocoupler detection switch 110 can be controlled to close at this time to perform detection of the open optocoupler 130. Wherein the confirmation signal is generated when the cut-off detection optocoupler 180 is turned off.
In this embodiment, the blocking detection optocoupler 180 is arranged to confirm that the signal transmitted by the on-off switch 150 is blocked, so that the erroneous judgment of the detection result caused by the fact that the on-off switch 170 is not normally opened and is still closed is avoided, and the detection accuracy is further improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating a control method of a remote signaling open-in self-test system according to an embodiment. In one embodiment, as shown in fig. 4, a control method of a remote communication open self-test system includes:
and step S410, controlling the n opto-coupler detection switches 110 to be in a closed state when the set time is reached.
The set time is a preset time and is used for instructing the controller 120 to trigger the self-detection. Alternatively, the set time may be set as desired, for example, at zero point every day, and the self-test is performed every 24 hours.
In this embodiment, n optical coupling detection switches 110 are configured to correspond to n open circuits, one end of each optical coupling detection switch 110 is electrically connected to the first power source 140, the other end of each optical coupling detection switch 110 is electrically connected to an input end of one open optical coupler 130, n optical coupling detection switches 110 are used to be in a closed state when performing self-detection, and n is a natural number greater than 1. Optionally, the n opto-coupler detection switches 110 may be sequentially turned on at a time, or may be turned on all at a time to shorten the detection time.
Step S420, if the detection signal is received after the optocoupler detection switch 110 is in the closed state, it is determined that the input optocoupler 130 corresponding to the received detection signal is normal.
In this step, if the detection signal is received, it indicates that the on-coupler 130 can normally operate, and it is determined that the on-coupler 130 corresponding to the received detection signal is normal.
In this embodiment, whether the open optical coupler 130 is normal or not is detected by controlling the optical coupler detection switch 110 to be in a closed state, and if the open optical coupler 130 is abnormal, the abnormal open optical coupler 130 can be known in time, so that the running state of the device can be checked in time and a new optical coupler can be replaced when the open optical coupler 130 is abnormal, the defect of the device cannot be detected normally due to damage of the optical coupler is avoided, and the timeliness of abnormal feedback of the running of the device is improved. In addition, the technical scheme of the embodiment can automatically detect through the controller 120 without manual intervention.
Referring to fig. 5, fig. 5 is a flowchart illustrating another control method of a remote access self-test system according to an embodiment. This embodiment is a further refinement of the above embodiment. In one embodiment, as shown in fig. 5, another control method of a remote-communication open-self-test system includes:
step S510, when the set time is reached, controlling the open/close switch 170 to be in an off state to close the signal transmitted through the open switch 150.
In the present embodiment, the on-off switch 170 is configured to be in an off state before detecting whether the on-incoupling 130 is normal, so as to off the signal transmitted through the on-off switch 150.
And step S520, judging whether a confirmation signal sent by the partition detection optocoupler 180 is received.
Step S530, if the confirmation signal is received, controlling the n opto-coupler detection switches 110 to be in a closed state.
In this step, if a confirmation signal sent by the cut-off detection optocoupler 180 is received, it may be determined that the cut-in cut-off switch 170 is normally opened, and the optocoupler detection switch 110 may start to be controlled to be closed.
And step S540, controlling the n opto-coupler detection switches 110 to be in a closed state.
Step S550, if the detection signal is received after the optocoupler detection switch 110 is in the closed state, determining that the input optocoupler 130 corresponding to the received detection signal is normal.
In this embodiment, after the switch-in isolating switch 170 is controlled to be turned off, the optical coupler detection switch 110 is controlled to be turned on to detect whether the switch-in optical coupler 130 is normal, so that the problem that in the process of detecting the switch-in optical coupler 130, the switch-in switch 150 corresponding to the switch-in optical coupler 130 is just turned on to cause an inaccurate detection result is solved, and the accuracy of detection of the remote signaling switch-in self-detection system is improved.
In another embodiment, steps S520 and S530 may not be required. It can be understood that, by adding step S520 and step S530, the n opto-coupler detection switches 110 are controlled to be in the closed state only by receiving the confirmation signal, thereby avoiding the erroneous judgment of the detection result caused by that the open-in partition switch 170 is not normally opened and is still closed, and further improving the accuracy of detection.
Referring to fig. 6, fig. 6 is a flowchart illustrating another control method of a remote access self-test system according to an embodiment. In one embodiment, as shown in fig. 6, another control method of a remote-communication incoming self-test system includes:
step S610, when the set time is reached, controlling the open/close switch 170 to be in an open state to close the signal transmitted through the open/close switch 150.
Step S620, determining whether an acknowledgement signal sent by the partition detection optocoupler 180 is received.
Step S630, if the confirmation signal is received, controlling the n opto-coupler detection switches 110 to be in a closed state.
And step S640, controlling the n optocoupler detection switches 110 to be in a closed state.
Step S650, if the detection signal is received after the optocoupler detection switch 110 is in the closed state, it is determined that the input optocoupler 130 corresponding to the received detection signal is normal.
In step S660, after detecting whether the open optocoupler 130 is normal, the optocoupler detection switch 110 is controlled to be turned off.
Step S670, if a detection signal sent by the normal on-hook optocoupler 130 is received, determining that the optocoupler detection switch 110 corresponding to the normal on-hook optocoupler 130 that sends the detection signal is abnormal.
In this step, after the optocoupler detection switch 110 is controlled to be turned off, the controller 120 should not receive the detection signal of the normal on-optocoupler 130. If the detection signal of the normal on-hook optocoupler 130 continues to be received, it is determined that the optocoupler detection switch 110 corresponding to the normal on-hook optocoupler 130 which sends the detection signal is abnormal.
In this embodiment, after detecting whether the open optical coupler 130 is normal, the opto-coupler detection switch 110 is further controlled to be turned off to determine whether the opto-coupler detection switch 110 is normally turned off, so that it is avoided that the opto-coupler detection switch 110 is not normally turned off, and a subsequent received signal is sent out when the running equipment is considered to be abnormal, thereby improving the accuracy of the abnormal running determination of the running equipment.
Referring to fig. 7, fig. 7 is a flowchart illustrating another control method of a remote access self-test system according to an embodiment. In one embodiment, as shown in fig. 7, another control method of a remote-communication open-self-test system includes:
step S710, when the set time is reached, controlling the open/close switch 170 to be in an open state to close the signal transmitted through the open/close switch 150.
And step S720, judging whether a confirmation signal sent by the partition detection optocoupler 180 is received.
And step S730, if the confirmation signal is received, controlling the n opto-coupler detection switches 110 to be in a closed state.
And step S740, controlling the n opto-coupler detection switches 110 to be in a closed state.
Step S750, if the detection signal is received after the optocoupler detection switch 110 is in the closed state, it is determined that the input optocoupler 130 corresponding to the received detection signal is normal.
Step S760, after detecting whether the open optocoupler 130 is normal, controlling the optocoupler detection switch 110 to be turned off.
Step S770, if a detection signal sent by the normal on-coupler 130 is received, determining that the opto-coupler detection switch 110 corresponding to the normal on-coupler 130 sending the detection signal is abnormal.
And step S780, controlling the opening and closing of the opening and closing switch 170.
Step S790, if a confirmation signal sent by the partition detection optocoupler 180 is received, it is determined that the open partition switch 170 is abnormal.
In this step, if the on off switch 170 is controlled to be closed, the controller 120 should not receive the confirmation signal of the normal on optocoupler 130. And if the confirmation signal sent by the cut-off detection optocoupler 180 is continuously received, determining that the switch-in cut-off switch 170 is switched on.
In this embodiment, the on-off switch 170 is controlled to be closed after the optical coupler detection switch 110 is detected to be normally opened, so that the on-off switch 170 is normally closed, the problem that the on-off switch 170 is not normally closed, which causes a subsequent abnormal signal which cannot be sent when the equipment is operated abnormally, is avoided, and the timeliness of abnormal feedback of the operation of the equipment is improved.
