Description

Technical Field

[0001] This invention relates to the field of circuit control technology, and in particular to a hard-plate control method, device, switch, and medium. Background Technology

[0002] During the substation sequential control operation, the operation involving the activation and deactivation of hard pressure plates cannot be remotely controlled through the back-end program and must be performed on-site by personnel, which greatly affects the efficiency and accuracy of the operation.

[0003] In existing technologies, remote activation or deactivation of the pressure plate input or output function is achieved by designing the program logic of the series output soft pressure plate in the original hard pressure plate logic circuit. However, designing the program logic of the series output soft pressure plate will bring a series of problems such as protection program version testing and management, making the software resources occupied by the substation sequential control operation process increasingly large. Moreover, designing the program logic of the series output soft pressure plate requires research and development, testing, and maintenance processes, making the substation sequential control operation process cumbersome and inconvenient. Summary of the Invention

[0004] Based on this, it is necessary to address the technical problem that the remote operation of enabling or disabling the pressure plate's input or output function by designing the program logic of the series-connected soft pressure plate in the existing technology is cumbersome and not conducive to the implementation by the staff. Therefore, a hard pressure plate control method, device, switch and medium are proposed.

[0005] A first aspect provides a method for controlling a rigid pressure plate, characterized in that the method is used to control a rigid pressure plate control device in a relay protection device. The rigid pressure plate control device includes: a base, a movable pressure plate, a signal unit, a control unit, and a communication unit. The base is provided with a first contact, a second contact, a third contact, a fourth contact, a fifth contact, a sixth contact, a seventh contact, an eighth contact, and a ninth contact. The first contact is connected to the positive terminal of the original hard pressure plate input / output node of the relay protection device; the second contact is connected to the negative terminal of the original hard pressure plate input / output node of the relay protection device; the third contact is connected to the positive terminal of the local closing sub-unit in the signal unit; the fourth contact is connected to the negative terminal of the local closing sub-unit in the signal unit; the fifth contact is connected to the positive terminal of the local separating sub-unit in the signal unit; the sixth contact is connected to the negative terminal of the local separating sub-unit in the signal unit; and the seventh contact is connected to the original hard pressure plate input / output node of the relay protection device via the first node. The positive terminal of the open / close node is connected to the negative terminal of the original hard platen open / close node of the relay protection device. The ninth terminal is movably connected to the maintenance subunit in the signal unit through the movable plate. After the movable plate is completely removed, the ninth terminal connects to the maintenance subunit in the signal unit. The movable plate is used to connect the first terminal and the second terminal, and simultaneously connect the third terminal and the fourth terminal. Alternatively, the movable plate is used to connect the fifth terminal and the sixth terminal, and simultaneously connect the seventh terminal and the eighth terminal. When the movable plate connects the fifth terminal and the sixth terminal, and simultaneously connects the seventh terminal and the eighth terminal, the control unit responds to the control signal of the communication unit to control the opening and closing of the first terminal, and to control the opening and closing of the second terminal of the remote closing subunit and / or the third terminal of the remote separating subunit in the signal unit.

[0006] The hard plate control method includes:

[0007] Obtain user request information for the target hard platen, and determine the working mode of the target hard platen based on the request information;

[0008] According to the working mode, control the position of the movable pressure plate on the target hard pressure plate so that the movable pressure plate connects the first contact and the second contact, and simultaneously connects the third contact and the fourth contact; or, so that the movable pressure plate connects the fifth contact and the sixth contact, and simultaneously connects the seventh contact and the eighth contact; or, the movable pressure plate is completely removed, and the first contact, the second contact, the third contact, the fourth contact, the fifth contact, the sixth contact, the seventh contact, and the eighth contact are all disconnected, and the ninth contact connects to the signal unit maintenance subunit.

[0010] When the movable pressure plate is completely removed, the first contact, the second contact, the third contact, the fourth contact, the fifth contact, the sixth contact, the seventh contact, and the eighth contact are all disconnected, and the ninth contact is connected to the signal unit maintenance subunit to achieve safe isolation of the target hard pressure plate.

[0011] Optionally, the control unit includes a miniature dual-position relay;

[0012] The step of controlling the opening and closing of the first node based on the control information includes:

[0013] Based on the control information, a control signal is generated for the miniature dual-position relay, and the control signal is sent to the miniature dual-position relay through the input and output nodes of the miniature dual-position relay to control the excitation / demagnetization of the two coils in the miniature dual-position relay, thereby controlling the opening and closing of the first node.

[0015] The method further includes:

[0016] The control signal of the miniature dual-position relay is acquired, and the status information of the miniature dual-position relay is identified based on the control signal;

[0017] Based on the status information, select the indicator node corresponding to the status information from the second indicator node and the first indicator node, and use it as the target indicator node;

[0018] When the (1,0) signal of the miniature dual-position relay is received, the first indicator node is closed to energize the first indicator light.

[0019] When the miniature dual-position relay receives a (0,1) signal, it controls the second indicator node to close, thereby energizing the second indicator light.

[0020] Optionally, the step of obtaining the user's request information for the target hard platen includes:

[0021] Obtain the user's initial request information and identify the content information of the initial request information;

[0022] Based on the aforementioned content information, the identity information of the hard pressure plate to be controlled is determined;

[0023] Based on the identity recognition information and the preset hard plate setting data, determine whether the hard plate to be controlled is controllable;

[0024] If the hard pressure plate to be controlled is controllable, then the hard pressure plate to be controlled is taken as the target hard pressure plate, and the initial request information is taken as the request information for the target hard pressure plate;

[0025] If the controllable hard platen is uncontrollable, an error message is generated and displayed.

[0033] The preset operation results in the preset operation data and the change results in the state change data are matched to obtain a second matching result;

[0034] If both the first matching result and the second matching result are successful, then the steps of generating display information and displaying the display information continue;

[0035] If at most one of the first matching result and the second matching result is a successful match, then the steps of generating alarm information and displaying the alarm information continue.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] The hard plate control method provided in this embodiment of the invention can be applied to, for example... Figure 1 In the application environment, the system includes a remote scheduling control platform 1, a station control layer 2, a switch 3, a pressure plate management machine 4, and a hard pressure plate control device 7 consisting of a target hard pressure plate 5 and a control terminal 6. The remote scheduling control platform 1 interacts with the station control layer 2, the switch 3 interacts with the station control layer 2, the pressure plate management machine 4 receives instructions from the switch 3 and communicates with the hard pressure plate control device 7, and the hard pressure plate control device 7 controls the action of the target hard pressure plate 5 in the pressure plate control device 7 through the control terminal 6.

[0057] The signal unit receives the local alignment signal, local separation signal, remote alignment signal, and remote separation signal from the target hard pressure plate 5, and transmits them sequentially to the pressure plate management machine 4, the switch 3, the station control layer 2, and the remote scheduling control platform 1 via the communication module, so as to display the local alignment signal, local separation signal, remote alignment signal, and remote separation signal.

[0058] The present invention will now be described in detail through specific embodiments.

[0059] like Figure 2 - Figure 5As shown, the rigid plate control device 100 includes: a base 110, a movable plate 120, a signal unit 130, a control unit 140, and a communication unit 150. The base 110 is provided with a first contact 111, a second contact 112, a third contact 113, a fourth contact 114, a fifth contact 115, a sixth contact 116, a seventh contact 117, an eighth contact 118, and a ninth contact 119. The first contact 111 and the second contact 112 are respectively connected to the positive and negative terminals of the input / output nodes of the original rigid plate of the relay protection device. The third contact 113 is connected to the positive terminal of the local merging subunit 131 in the signal unit 130. The fourth contact 114 is connected to the ninth contact 119. 4. The fifth contact 115 is connected to the negative terminal of the local merging subunit 131 in the signal unit 130; the sixth contact 116 is connected to the negative terminal of the local merging subunit 132 in the signal unit 130; the seventh contact 117 is connected to the positive terminal of the original hard plate input / output node of the relay protection device through the first node 210; the eighth contact 118 is connected to the negative terminal of the original hard plate input / output node of the relay protection device; and the ninth contact 119 is movably connected to the maintenance subunit 133 in the signal unit 130 through the movable pressure plate 120, wherein the movable pressure plate 120 is completely removed. Afterwards, the ninth contact 119 connects the positive and negative terminals of the maintenance subunit 133 in the signal unit 130. The movable pressure plate 120 is used to connect the first contact 111 and the second contact 112, and simultaneously connect the third contact 113 and the fourth contact 114; or, the movable pressure plate 120 is used to connect the fifth contact 115 and the sixth contact 116, and simultaneously connect the seventh contact 117 and the eighth contact 118. When the movable pressure plate 120 connects the fifth contact 115 and the sixth contact 116, and simultaneously connects the seventh contact 117 and the eighth contact 118, the control unit 140 responds. The communication unit 150 receives and sends a remote control signal to control the opening and closing of the first node 210. At the same time, the control unit 140 responds to the remote control signal received and sent by the communication unit 150 to control the second node 220 of the remote merging subunit 134 in the signal unit 130 and / or the third node 230 of the remote separating subunit 135 in the signal unit 130. Simultaneously, the control unit 140 responds to the remote control signal received by the communication unit 150 to control the first indicator node 240 of the green light 310 in the control unit 140 and / or the second indicator node 250 of the red light 320 in the control unit 140.

[0060] For example, when the movable pressure plate 120 is inserted into the base 110, the insulating support column on the movable pressure plate is inserted into the through hole where the ninth contact 119 is located on the base 110, thereby causing the ninth contact 119 to disconnect from the maintenance subunit 133 in the signal unit 130.

[0061] For example, such as Figure 3 As shown, the target hard plate is in local mode. When the movable plate 120 connects the first contact 111 and the second contact 112, and at the same time connects the third contact 113 and the fourth contact 114, the local closing subunit 131 in the signal unit 130 receives the local closing signal from the hard plate 100. At the same time, the original hard plate of the relay protection device is connected.

[0062] Similarly, such as Figure 2 As shown, the target hard plate is in remote mode. The movable plate 120 connects the fifth contact 115 and the sixth contact 116, and at the same time connects the seventh contact 117 and the eighth contact 118. The local locating subunit 132 in the signal unit 130 receives the local locating signal from the hard plate 100. Meanwhile, whether the original hard plate in the relay protection device is connected depends on the opening and closing of the first node 210.

[0063] Please see Figure 6 As shown, Figure 6 A schematic flowchart of the hard plate control method provided in an embodiment of the present invention includes the following steps:

[0064] S101. Obtain user request information for the target hard plate in the hard plate control device, and determine the working mode of the target hard plate based on the request information.

[0065] For example, the working modes of the hard pressure plate can be divided into local mode, remote mode and maintenance mode. In the local mode, the staff needs to perform the operation of putting on and taking off the pressure plate on site. In the remote mode, the staff can control the putting on and taking off of the pressure plate remotely. The putting on and taking off of the pressure plate can be simply understood as the opening and closing of a circuit. When the pressure plate is put on, the circuit is connected. When the pressure plate is taken off, the circuit is disconnected.

[0066] For example, the process of determining the working mode of the hard platen based on the request information includes information for characterizing the specific working mode of the platen. For example, the identification information of the local mode is set to 1, and the identification information of the remote mode is set to 0. The request information includes 0 or 1 to characterize the specific working mode of the specific platen.

[0067] It should be understood that the target hard plate is one or more of the aforementioned hard plates, that is, the target hard plate also includes: a base 110, a movable pressure plate 120, a signal unit 130, a control unit 140, and a communication unit 150. The base 110 is provided with a first contact 111, a second contact 112, a third contact 113, a fourth contact 114, a fifth contact 115, a sixth contact 116, a seventh contact 117, an eighth contact 118, and a ninth contact 119. The first contact 111 is connected to the positive terminal of the input / output node of the original hard plate of the relay protection device, and the second contact 112 is connected to the relay protection device. The negative terminal of the input / output node of the original hard platen is connected to the negative terminal of the signal unit 130. The third contact 113 is connected to the positive terminal of the local merging subunit 131 in the signal unit 130. The fourth contact 114 is connected to the negative terminal of the local merging subunit 131 in the signal unit 130. The fifth contact 115 is connected to the positive terminal of the local terminating subunit 132 in the signal unit 130. The sixth contact 116 is connected to the negative terminal of the local terminating subunit 132 in the signal unit 130. The seventh contact 117 is connected to the positive terminal of the input / output node of the original hard platen of the relay protection device through the first node 210. The eighth contact 118 is connected to the relay. The negative terminal of the original hard plate inlet / outlet node of the protection device, the ninth contact 119, is movably connected to the maintenance subunit 133 in the signal unit 130 through the movable plate 120. After the movable plate 120 is completely removed, the ninth contact 119 connects to the maintenance subunit 133 in the signal unit 130. The movable plate 120 is used to connect the first contact 111 and the second contact 112, and simultaneously connect the third contact 113 and the fourth contact 114. Alternatively, the movable plate 120 is used to connect the fifth contact 115 and the sixth contact 116, and simultaneously connect the third contact 111 and the fourth contact 114. The seventh contact 117 and the eighth contact 118 are connected. When the movable pressure plate 120 connects the fifth contact 115 and the sixth contact 116, and simultaneously connects the seventh contact 117 and the eighth contact 118, the control unit 140 responds to the control signal of the communication unit 150 to control the opening and closing of the first node 210. At the same time, the control unit 140 responds to the control signal of the communication unit 150 to control the second node 220 of the remote merging subunit 134 in the signal unit 130 and / or the third node 230 of the remote separating subunit 135 in the signal unit 130.

[0068] S102. Control the position of the movable pressure plate on the target hard pressure plate according to the working mode, so that the movable pressure plate connects the first contact and the second contact, and at the same time connects the third contact and the fourth contact, or, so that the movable pressure plate connects the fifth contact and the sixth contact, and at the same time connects the seventh contact and the eighth contact.

[0069] For example, when the hard plate needs to work in local mode, that is, the hard plate is put in and taken out by vertically inserting the movable plate, the movable plate connects the first contact and the second contact, and at the same time connects the third contact and the fourth contact to the local closed position; then the movable plate is inserted horizontally to connect the fifth contact and the sixth contact, and at the same time connects the seventh contact and the eighth contact to the local separated position.

[0070] S103. When the movable pressure plate connects the fifth contact and the sixth contact, and simultaneously connects the seventh contact and the eighth contact, the user's control information is obtained, and the opening and closing of the first node is controlled based on the control information to remotely control the deployment and retraction of the target hard pressure plate.

[0071] For example, when the movable pressure plate connects the fifth and sixth contacts, and simultaneously connects the seventh and eighth contacts, it can be understood that the hard pressure plate is in remote mode. That is, the control unit controls the first node to determine whether the relay protection device is connected. When the first node is disconnected, the hard pressure plate is in a remote open state; when the first node is closed, the hard pressure plate is in a remote closed state.

[0072] S104. When the movable pressure plate is completely removed, the first contact, the second contact, the third contact, the fourth contact, the fifth contact, the sixth contact, the seventh contact, and the eighth contact are all disconnected, and the ninth contact is connected to the signal unit maintenance subunit to achieve safe isolation of the target hard pressure plate.

[0073] For example, when the movable pressure plate is inserted into the base, the support column on the movable pressure plate inserts into the through hole where the ninth contact is located on the base, thereby causing the ninth contact to disconnect from the maintenance subunit in the signal unit; conversely, as... Figure 4 As shown, the target hard plate is in maintenance mode. When the movable plate is completely removed, the first contact, the second contact, the third contact, the fourth contact, the fifth contact, the sixth contact, the seventh contact, and the eighth contact are all disconnected, and the ninth contact is connected to the signal unit maintenance subunit to achieve safe isolation of the target hard plate.

[0074] This application obtains user request information for a target hard platen and determines the operating mode of the target hard platen based on the request information. According to the operating mode, it controls the position of the movable platen on the target hard platen, so that the movable platen connects the first and second contacts, and simultaneously connects the third and fourth contacts, or connects the fifth and sixth contacts, and simultaneously connects the seventh and eighth contacts. When the movable platen connects the fifth and sixth contacts, and simultaneously connects the seventh and eighth contacts, it obtains user control information and controls the opening and closing of the first node based on the control information to control the deployment and retraction of the target hard platen. This allows the platen to have both local and remote deployment and retraction operating modes, eliminating the need for on-site personnel and improving the operational efficiency of circuit maintenance and inspection.Meanwhile, by changing the physical structure of the pressure plate through parallel connection of local and remote sub-pressure plates, the program logic for designing a series outlet soft pressure plate is eliminated, reducing the process of program development and program logic testing. The hard pressure plate 100 includes: a base 110, a movable pressure plate 120, a signal unit 130, a control unit 140, and a communication unit 150. The base 110 is provided with a first contact 111, a second contact 112, a third contact 113, a fourth contact 114, a fifth contact 115, a sixth contact 116, a seventh contact 117, an eighth contact 118, and a ninth contact 119. The first contact 111 and the second contact 119... Contact 112 is connected to the positive and negative terminals of the input / output node in the relay protection device, respectively. The third contact 113 and the fourth contact 114 are connected to the positive and negative terminals of the local closing subunit 131 in the signal unit 130, respectively. The fifth contact 115 and the sixth contact 116 are connected to the positive and negative terminals of the local separating subunit 132 in the signal unit 130, respectively. The seventh contact 117 is connected to the positive terminal of the input / output node of the original hard platen of the relay protection device through the first node 210. The eighth contact 118 is connected to the negative terminal of the input / output node of the original hard platen of the relay protection device. The ninth contact 119... The movable pressure plate 120 is movably connected to the maintenance subunit 133 in the signal unit 130. After the movable pressure plate 120 is completely removed, the ninth contact 119 connects the positive and negative terminals of the maintenance subunit 133 in the signal unit 130. The movable pressure plate 120 is used to connect the first contact 111 and the second contact 112, and simultaneously connect the third contact 113 and the fourth contact 114; or, the movable pressure plate 120 is used to connect the fifth contact 115 and the sixth contact 116, and simultaneously connect the seventh contact 117 and the eighth contact 118. When the movable pressure plate 120 connects the fifth contact 115 and the sixth contact 116, and simultaneously connects the seventh contact 117 and the eighth contact 118, the control unit 140 responds to the remote control signal received and sent by the communication unit 150 to control the opening and closing of the first node 210. Simultaneously, the control unit 140 responds to the remote control signal received and sent by the communication unit 150 to control the opening and closing of the second node 220 of the remote closing subunit 134 in the signal unit 130 and / or the third node 230 of the remote opening subunit 135 in the signal unit 130. In one possible implementation, the control unit includes a miniature dual-position relay.

[0075] The step of controlling the opening and closing of the first node based on the control information includes:

[0076] Based on the control information, a control signal is generated for the miniature dual-position relay, and the control signal is sent to the miniature dual-position relay through the input and output nodes of the miniature dual-position relay to control the excitation / demagnetization of the two coils in the miniature dual-position relay, thereby controlling the opening and closing of the first node.

[0077] For example, the miniature dual-position relay is a relay that forms a closed magnetic circuit by two electromagnets and a common armature. The two coils of the miniature dual-position relay need to receive fixed signals to achieve demagnetization / excitation. For example, when the signal of the first coil of the miniature dual-position relay is 1 and the signal of the second coil of the miniature dual-position relay is 0, the miniature dual-position relay is energized; when the signal of the first coil of the miniature dual-position relay is 0 and the signal of the second coil of the miniature dual-position relay is 1, the miniature dual-position relay is demagnetized; and when the signal of the first coil of the miniature dual-position relay is 0 and the signal of the second coil of the miniature dual-position relay is 0, the miniature dual-position relay does not change its state; when the signal of the first coil of the miniature dual-position relay is 1 and the signal of the second coil of the miniature dual-position relay is 1, the miniature dual-position relay also does not change its state.

[0078] For example, when the miniature dual-position relay is energized, it generates a magnetic force to attract the first node 210, causing the first node 210 to close. At this time, the pressure plate is in a remote engagement state. Conversely, when the miniature dual-position relay is demagnetized, it generates a magnetic force to attract the first node 210, causing the first node 210 to open. At this time, the pressure plate is in a remote disengagement state.

[0079] In one possible implementation, the target hard plate further includes: a first indicator node 240, a second indicator node 250, a first indicator light 310, and a second indicator light 320. The first indicator light 310 is connected to the control unit 140 through the first indicator node 240, and the second indicator light 320 is connected to the control unit 140 through the second indicator node 250. The first indicator node is used to respond to the (1,0) signal of the miniature dual-position relay, and the second indicator node is used to respond to the (0,1) signal of the miniature dual-position relay. Both the (1,0) signal and the (0,1) signal are control signals of the miniature dual-position relay.

[0080] The method further includes:

[0081] The control signal of the miniature dual-position relay is acquired, and the status information of the miniature dual-position relay is identified based on the control signal;

[0082] Based on the status information, select the indicator node corresponding to the status information from the second indicator node and the first indicator node, and use it as the target indicator node;

[0083] When the (1,0) signal of the miniature dual-position relay is received, the first indicator node is closed to energize the first indicator light.

[0084] When the miniature dual-position relay receives a (0,1) signal, it controls the second indicator node to close, thereby energizing the second indicator light.

[0085] For example, the first indicator light is set to green and the second indicator light is set to red. The different colored indicator lights represent the current working status of the pressure plate, so that when the staff conducts on-site inspections of the pressure plate in remote mode, they can intuitively see its working status without having to log in to the control center or other back-end management systems, which facilitates inspection and maintenance.

[0086] In one possible implementation, the step of obtaining the user's request information for the target hard platen includes:

[0087] Obtain the user's initial request information and identify the content information of the initial request information;

[0088] Based on the aforementioned content information, the identity information of the hard pressure plate to be controlled is determined;

[0089] Based on the identity recognition information and the preset hard plate setting data, determine whether the hard plate to be controlled is controllable;

[0090] If the hard pressure plate to be controlled is controllable, then the hard pressure plate to be controlled is taken as the target hard pressure plate, and the initial request information is taken as the request information for the target hard pressure plate;

[0091] If the controllable hard platen is uncontrollable, an error message is generated and displayed.

[0092] For example, users often control multiple hard pressure plates through a hard pressure plate management machine. For instance, a user may control 30 hard pressure plate control devices on the same screen through a hard pressure plate control device. Among the multiple hard pressure plates, there may be specific hard pressure plates that are not allowed to be operated. Therefore, to ensure safety, it is necessary to match the identification information of the hard pressure plate to be controlled with the specific hard pressure plate. If the hard pressure plate to be controlled is not the specific hard pressure plate, the control process continues.

[0093] Users use the pressure plate management unit to communicate with the station control layer through a switch, enabling the station control layer to remotely control the target pressure plate via the pressure plate management unit.

[0094] Users can perform sequential control operations on the target hard pressure plate through the pre-set sequential control program in the scheduling background, via the station control layer, switch, pressure plate management machine, and hard pressure plate control device.

[0095] In one possible implementation, the method further includes:

[0096] Obtain preset operation data corresponding to the target hard plate;

[0097] The signal unit acquires the state change data of the target hard plate, and the preset operation data is matched with the state change data.

[0098] If the state change data matches the preset operation data, then display information is generated and displayed.

[0099] If the state change data does not match the preset operation data, an alarm message is generated and displayed.

[0100] For example, by acquiring and displaying the status change data of different sub-plates, managers can monitor the status of each plate in real time. They can also compare the status change data with guidance documents such as operation manuals to promptly identify operational errors by staff.

[0101] Because the circuit operation process requires strict adherence to the execution order and content of the steps, it is necessary to match the change data of the pressure plates in terms of both execution order and execution content. Therefore, when obtaining the state change data of different sub-pressure plates, the state change order of each sub-pressure plate should be recorded. For example, during the operation, it can be recorded that the local sub-pressure plate is operated at time AA and the remote sub-pressure plate is operated at time BB. Then, the change data of the pressure plates can be sorted in chronological order, where AA and BB represent time points.

[0102] In one possible implementation, the step of matching the preset operation data and the first state change data includes:

[0103] The preset operation sequence in the preset operation data is matched with the change sequence in the state change data to obtain a first matching result;

[0104] The preset operation results in the preset operation data and the change results in the state change data are matched to obtain a second matching result;

[0105] If both the first matching result and the second matching result are successful, then the steps of generating display information and displaying the display information continue;

[0106] If at most one of the first matching result and the second matching result is a successful match, then the steps of generating alarm information and displaying the alarm information continue.

[0107] For example, by utilizing state change data and the preset operation data, it is possible to quickly identify staff erroneous operations and then correct the errors in a timely manner.

[0108] For example, the preset operation data is a document such as a predictive operation manual used to guide staff in operating the circuit. The preset operation data includes at least the operation sequence of different pressure plates and the operation content of each pressure plate.

[0109] For example, when an alarm message is generated, the non-matching content needs to be displayed. Therefore, the non-matching result is used as the target matching result, and then the alarm message is generated based on the target matching result. This allows staff to intuitively understand the location of the error / the content of the error.

[0110] In one possible implementation, the local alignment subunit is used to acquire the local alignment signal of the target hard platen, and the local alignment subunit is also used to send the local alignment signal out for display via the communication unit; the local separation subunit is used to acquire the local separation signal of the target hard platen, and the local separation subunit is also used to send the local separation signal out for display via the communication unit; the remote alignment subunit is used to acquire the remote alignment signal of the target hard platen, and the remote alignment subunit is also used to send the remote alignment signal out for display via the communication unit; the remote separation subunit is used to acquire the remote separation signal of the target hard platen, and the remote separation subunit is also used to send the remote separation signal out for display via the communication unit; and the maintenance subunit is used to acquire the maintenance signal of the target hard platen, and the maintenance subunit is also used to send the maintenance signal out for display via the communication unit.

[0111] For example, by acquiring and displaying local separation signals, local merging signals, remote separation signals, and remote merging signals, i.e., acquiring the status of the hard pressure plate, the control over the hard pressure plate can be improved, and the lag caused by the inability to acquire the status of the hard pressure plate in a timely manner can be avoided.

[0112] Secondly, a rigid pressure plate control system is provided, applied to a rigid pressure plate control device in a relay protection device. The rigid pressure plate control device includes: a base, a movable pressure plate, a signal unit, a control unit, and a communication unit. The base is provided with a first contact, a second contact, a third contact, a fourth contact, a fifth contact, a sixth contact, a seventh contact, an eighth contact, and a ninth contact. The first contact is connected to the positive terminal of the original hard pressure plate input / output node of the relay protection device; the second contact is connected to the negative terminal of the original hard pressure plate input / output node of the relay protection device; the third contact is connected to the positive terminal of the local closing subunit in the signal unit; the fourth contact is connected to the negative terminal of the local closing subunit in the signal unit; the fifth contact is connected to the positive terminal of the local separating subunit in the signal unit; the sixth contact is connected to the negative terminal of the local separating subunit in the signal unit; and the seventh contact is connected to the original hard pressure plate input / output node of the relay protection device through the first node. The positive terminal of the point, the eighth contact is connected to the negative terminal of the original hard plate input / output node of the relay protection device, the ninth contact is movably connected to the maintenance subunit in the signal unit through the movable plate, after the movable plate is completely removed, the ninth contact connects to the maintenance subunit in the signal unit, the movable plate is used to connect the first contact and the second contact, and at the same time connect the third contact and the fourth contact, or the movable plate is used to connect the fifth contact and the sixth contact, and at the same time connect the seventh contact and the eighth contact, when the movable plate connects the fifth contact and the sixth contact, and at the same time connects the seventh contact and the eighth contact, the control unit responds to the control signal of the communication unit to control the opening and closing of the first node, and control the opening and closing of the second node of the remote closing subunit and / or the third node of the remote separating subunit in the signal unit;

[0113] The hard plate control system includes:

[0114] The data acquisition module is used to acquire user request information for the target hard platen and determine the working mode of the target hard platen based on the request information.

[0115] The on-site deployment and deployment module is used to control the position of the movable pressure plate on the target hard pressure plate according to the working mode, so that the movable pressure plate connects the first contact and the second contact, and at the same time connects the third contact and the fourth contact.

[0116] The remote deployment / retraction module is used to acquire user control information when the movable pressure plate connects the fifth and sixth contacts, and simultaneously connects the seventh and eighth contacts, and controls the opening and closing of the first node based on the control information to control the deployment / retraction of the target hard pressure plate.

[0117] The maintenance module is configured to disconnect the first, second, third, fourth, fifth, sixth, seventh, and eighth contacts, and connect the ninth contact to the signal unit maintenance subunit when the movable pressure plate is completely removed, so as to achieve safe isolation of the target hard pressure plate.

[0118] By acquiring user request information for the target hard platen, and determining the working mode of the target hard platen based on the request information, the position of the movable platen on the target hard platen is controlled according to the working mode, so that the movable platen connects the first contact and the second contact, and simultaneously connects the third contact and the fourth contact, or connects the fifth contact and the sixth contact, and simultaneously connects the seventh contact and the eighth contact. When the movable platen connects the fifth contact and the sixth contact, and simultaneously connects the seventh contact and the eighth contact, user control information is acquired, and the opening and closing of the first node is controlled based on the control information to control the deployment and retraction of the target hard platen. This allows the platen to have two working modes: local deployment and retraction, and remote deployment and retraction. Furthermore, after the movable platen is completely removed, the ninth contact connects to the maintenance subunit in the signal unit, eliminating the need for on-site personnel and improving the operational efficiency of circuit maintenance and inspection. Meanwhile, by changing the physical structure of the pressure plate through parallel connection of local and remote sub-pressure plates, there is no need to design the program logic of the series outlet soft pressure plate, reducing the process of program development and program logic testing.
