[0038] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The secondary device wiring conversion method provided by the embodiments of the present application can be applied to, for example, Figure 1 the secondary device wiring conversion device shown as follows.

[0040] As Figure 1 shown, the secondary device wiring conversion device 100 includes: an input adapter 101, an input board 102, a relay assembly 103, an output board 104, an output adapter 105 and a main control chip 106.

[0041] Among them, the first interface of the input adapter 101 is connected to each node of the device to be replaced 107, the second interface is connected to the first input interface of the input board 102, the first output interface of the input board 102 is connected to the second input interface of the relay assembly 103, the second output interface of the relay assembly 103 is connected to the third input interface of the output board 104, the third output interface of the output board 104 is connected to the third interface of the output adapter 105, the fourth interface of the output adapter 105 is connected to each node of the device to be used 108, and the relay assembly 103 is electrically connected to the main control chip 106;

[0042] Among them, the input adapter 101 is respectively connected to the input board 102 and each node of the device to be replaced 107, and is used to conduct each node of the device to be replaced 107 with the input board 102, so that the input board 102 inherits the specific positions and node functions of each node of the device to be replaced 107.

[0043] Among them, the output adapter 105 is respectively connected to the output board 104 and each node of the device to be used 108, and is used to conduct each node of the device to be used 108 with the output board 104, so that the output board 104 inherits the specific positions and node functions of each node of the device to be replaced.

[0044] Among them, the relay assembly 103 is respectively connected to the input board 102 and the output board 104, and is electrically connected to the main control chip 106 at the same time. After receiving the conversion configuration instruction transmitted by the main control chip 106, the relay assembly 103 responds to the conversion configuration instruction to control the switches of each relay inside the relay assembly 103, so as to conduct each node with the same node function on the input board 102 and the output board 104, and achieve the purpose of device wiring conversion.

[0045] Specifically, when the input adapter 101 and the output adapter 105 are respectively connected to the device to be replaced 107 and the device to be used 108, the main control chip 106 obtains the first model file of the device to be replaced 107 and the second model file of the device to be used 108. Among them, the first model file contains the first mapping relationship between each node to be replaced in the device to be replaced 107 and the corresponding node function. The second model file contains the second mapping relationship between each node to be used in the device to be used 108 and the corresponding node function. Determine the third mapping relationship between each node to be replaced and each node to be used according to the first mapping relationship and the second mapping relationship, generate a conversion configuration instruction based on the third mapping relationship, and when the conversion configuration instruction meets the conduction condition, send the conversion configuration instruction to the relay component 103.

[0046] The relay component 103 responds to the conversion configuration instruction, turns on the corresponding relay switch, and conducts each node with the same node function on the input board 102 and the output board 104, achieving the purpose of device wiring conversion.

[0047] In one embodiment, the main control chip is a DSP (Digital Signal Processing) chip.

[0048] In one embodiment, the number of contacts of the first interface of the input adapter is the same as the number of contacts of the device to be replaced, and the number of contacts of the fourth interface of the output adapter is the same as the number of contacts of the device to be used.

[0049] Among them, the connection structure between the input adapter and the device to be replaced is as Figure 2 shown. The first interface 201 of the input adapter 101 is used to connect to the node to be replaced 202 of the device to be replaced 107. Therefore, the number of contacts on the first interface 201 of the input adapter 101 is the same as the number of contacts of the node to be replaced 202 of the device to be replaced 107. It can be understood that the contact structure of the interface of the input adapter 101 matches the structure of the node to be replaced 202. As Figure 2 shown in, if the structure of the node to be replaced 202 is a pin structure, then the contact structure of the first interface 201 is a hole structure.

[0050] The connection structure between the output adapter and the device to be used is as Figure 3 shown. The fourth interface 301 of the output adapter 105 is used to connect to the contact to be used 302 of the device to be used 108. Therefore, the number of contacts on the fourth interface 301 of the output adapter 105 is the same as the number of contacts of the contact to be used 302. It can be understood that the contact structure of the fourth interface 301 matches the structure of the contact to be used 302. As Figure 3As shown in [figure], if the structure of the contact 302 to be used is a pin structure, then the structure of the contact of the fourth interface 301 is a hole structure.

[0051] In one embodiment, the number of contacts of the second interface of the input adapter, the first input port of the input board, the second input port of the relay assembly, the second output port of the relay assembly, the third output port of the input board, and the third interface of the output adapter are all standard contact numbers.

[0052] Specifically, in order to make the secondary equipment wiring conversion device more universal and applicable to the conversion of secondary equipment produced by various manufacturers, the number of contacts of the second interface of the input adapter, the first input port of the input board, the second input port of the relay assembly, the second output port of the relay assembly, the third output port of the input board, and the third interface of the output adapter in the secondary equipment wiring conversion device are all designed as standard contact numbers. Among them, the standard contact number refers to the contact number that can cover all node functions.

[0053] For example, if there are 40 node functions of the secondary equipment on the current market, then the maximum number of nodes of the secondary equipment produced by the manufacturer is 40. At this time, the standard contact number can be set to 40 so that the prepared secondary equipment wiring conversion device can be applicable to the conversion of secondary equipment produced by all manufacturers on the market. In actual use, only the adaptability of the first interface of the input adapter to the device to be replaced and the adaptability of the fourth interface of the output adapter to the device to be used need to be maintained, which greatly saves the cost of secondary equipment wiring conversion and improves the safety and stability of the power system operation.

[0054] In one embodiment, the secondary equipment wiring conversion device is further provided with an alarm device, and the alarm device is connected to the alarm relay in the relay assembly for continuing to alarm when the alarm relay is turned on.

[0055] Specifically, when the main control chip detects that the node functions corresponding to the nodes where the device to be replaced and the device to be used are turned on are inconsistent, it means that the node turn-on is incorrect. At this time, the main control chip will generate an alarm instruction, send the alarm instruction to the relay assembly, control the alarm relay in the relay assembly to turn on, and the alarm device will alarm after being powered on. It can be understood that the alarm device can be a buzzer, an indicator light, etc., and the present application does not limit this. Through the alarm device, the staff can timely know the situation corresponding to the internal nodes during the replacement of the secondary equipment, avoiding the occurrence of equipment use failures caused by incorrect node turn-on, and maintaining the safety and stability of the power system operation.

[0056] In one embodiment, the secondary equipment wiring conversion device is further provided with a display device, which is connected to the main control chip and is used to receive the visual configuration sent by the main control chip. The visual configuration is generated according to the conversion configuration instruction.

[0057] Specifically, before officially issuing the conversion configuration instruction, the main control chip generates the visual configuration of each node to be replaced and each node to be used according to the conversion configuration instruction, and sends the visual configuration to the display device. The staff can see the corresponding relationship between each node to be replaced and each node to be used through the display device, and interact based on the display device and the main control chip. Through the display device, the staff can artificially determine or adjust the corresponding relationship between each node, effectively avoiding the situation of node configuration errors caused by computer logic deviation, improving the accuracy of node matching, and further enhancing the safety and stability of the power system operation.

[0058] In one embodiment, as Figure 4 shown, a secondary equipment wiring conversion device is provided. The device includes: an input adapter 401, an input board 402, a relay assembly 403, an output board 404, an output adapter 405, a main control chip 406, an alarm device 407, and a display device 408.

[0059] Among them, the input adapter 401 is connected to the device to be replaced 409 through the first interface 4011. The number of contacts on the first interface 4011 is the same as the number of contacts 4091 of the device to be replaced 409. For example, if the number of contacts 4091 of the device to be replaced 409 is 20, then the number of contacts on the first interface 4011 is also 20.

[0060] Among them, the input adapter 401 is connected to the first input interface 4021 of the input board 402 through the second interface 4012, conducting each node of the device to be replaced 409 with the input board 402, so that the input board 402 inherits the specific positions and node functions of each node of the device to be replaced 409.

[0061] The output adapter 405 is connected to the device to be used 410 through the fourth interface 4052. The number of contacts on the fourth interface 4052 is the same as the number of contacts 4101 of the device to be used 410. For example, if the number of contacts 4101 of the device to be used 410 is 20, then the number of contacts on the fourth interface 4052 is also 20.

[0062] The output adapter 405 is connected to the second input interface 4041 of the output board 404 through the third interface 4051, conducting each node of the device to be used 410 with the output board 404, so that the output board 404 inherits the specific positions and node functions of each node of the device to be used 410.

[0063] The input board 402 is connected to the relay assembly 403 through the first output interface, and the output board 404 is connected to the relay assembly 403 through the second output interface. The relay assembly 403 includes multiple relays and an alarm relay. Except for the alarm relay controlling the power-on of the alarm device 407, each of the other relays controls the connection between a node to be replaced and a node to be used.

[0064] The main control chip 406 is respectively communicatively connected to the relay assembly 403 and the display device 408. The main control chip 406 is configured to, when connecting the secondary equipment wiring conversion device to the equipment 409 to be replaced and the equipment 410 to be used, obtain the first model file of the equipment 409 to be replaced and the second model file of the equipment 410 to be used; the first model file contains the first mapping relationship between each node to be replaced and the node function in the equipment 409 to be replaced; the second model file contains the second mapping relationship between each node to be used and the node function in the equipment 410 to be used; according to the first mapping relationship and the second mapping relationship, determine the third mapping relationship between each node to be replaced and each node to be used; generate a conversion configuration instruction based on the third mapping relationship, and when the conversion configuration instruction meets the conduction condition, send the conversion configuration instruction to the relay assembly 403. The conversion configuration instruction is used to control the switches of the relays in the relay assembly 403 to conduct the corresponding nodes to be used for each node to be replaced.

[0065] The main control chip 406 is further configured to generate a visual configuration based on the conversion configuration instruction, send the visual configuration to the display device 408, and display the to-be-connected relationship between each node to the staff through the display device 408. The staff can interact based on the display device 408 and the main control chip 406 to manually determine or adjust the corresponding relationship between each node.

[0066] The main control chip 406 is further configured to generate an alarm instruction when the node matching verification fails, send the alarm instruction to the relay assembly 403, and control the alarm relay in the relay assembly 403 to turn on to make the alarm device 407 alarm.

[0067] In one embodiment, as Figure 5 shown, a secondary equipment wiring conversion method is provided. Taking the main control chip in Figure 1 as an example, the method includes the following steps:

[0068] Step 502, when connecting the secondary equipment wiring conversion device to the equipment to be replaced and the equipment to be used, obtain the first model file of the equipment to be replaced and the second model file of the equipment to be used; the first model file contains the first mapping relationship between each node to be replaced and the node function in the equipment to be replaced; the second model file contains the second mapping relationship between each node to be used and the node function in the equipment to be used.

[0069] Among them, the secondary equipment refers to the equipment that monitors, measures, controls, and protects the equipment in the substation that can transmit and distribute electric energy, such as measuring, relay protection, and metering devices. In order to avoid the situation where the secondary equipment fails due to long-term use, resulting in the substation being unable to operate safely, the secondary equipment in the substation has a certain service life, such as 12 years. The secondary equipment that needs to be replaced after reaching the service life is the equipment to be replaced, and the secondary equipment that will replace the equipment to be replaced and is about to be put into use is the equipment to be used.

[0070] Among them, the secondary equipment wiring conversion device is a device used to transfer the node functions of the equipment to be replaced to the equipment to be used. Specifically, when the secondary equipment needs to be replaced, the secondary equipment wiring conversion device is respectively connected to the equipment to be replaced and the equipment to be used, and the node functions of the equipment to be replaced are transferred to the equipment to be used through the secondary equipment wiring conversion device, making the conversion process simpler and faster.

[0071] Among them, the first model file is an information file pre-generated when the equipment to be replaced leaves the factory. The first model file contains the first mapping relationship between each node to be replaced and the node function in the equipment to be replaced. Specifically, when the manufacturer ships the equipment to be replaced, the node identifier and node function of each node in the equipment to be replaced are bound to obtain the first mapping relationship, and the first mapping relationship is stored to obtain the first model file. It can be understood that the first model file may also include information such as the usage parameters and service life of the equipment to be replaced.

[0072] Among them, the second model file is an information file pre-generated when the equipment to be used leaves the factory. The second model file contains the second mapping relationship between each node to be used and the node function in the equipment to be used. Specifically, when the manufacturer ships the equipment to be used, the node identifier and node function of each node in the equipment to be used are bound to obtain the second mapping relationship, and the second mapping relationship is stored to obtain the first model file. It can be understood that the second model file may also include information such as the usage parameters and service life of the equipment to be used.

[0073] Specifically, when the main control chip detects that the secondary equipment wiring conversion device is respectively connected to the equipment to be replaced and the equipment to be used, it obtains the first model file of the equipment to be replaced and the second model file of the equipment to be used. The first model file and the second model file are parsed to obtain the first mapping relationship that contains each node to be replaced and the node function in the equipment to be replaced, and the second mapping relationship that contains each node to be used and the node function in the equipment to be used. It can be understood that the first model file and the second model file can be pre-stored in the data storage system of the main control chip, and the main control chip can directly read them from the data storage system; or they can be stored in the cloud server, and the main control chip obtains them from the cloud server.

[0074] Step 504: Determine the third mapping relationship between each node to be replaced and each node to be used according to the first mapping relationship and the second mapping relationship.

[0075] The third mapping relationship is a one-to-one mapping relationship between each node to be replaced and each node to be used.

[0076] Specifically, after obtaining the first mapping relationship and the second mapping relationship, the main control chip determines the corresponding relationships between each node to be replaced and each node to be used according to the invariant in the first mapping relationship and the second mapping relationship, that is, the node function, and aggregates each corresponding relationship to obtain the third mapping relationship. For example, when the node function is overcurrent protection, if in the device to be replaced, according to the first mapping relationship, the node corresponding to overcurrent protection is 12, and in the device to be used, according to the second mapping relationship, the node corresponding to overcurrent protection is 6, then it can be determined that the node to be replaced 12 corresponds to the node to be used 6.

[0077] Step 506: Generate a conversion configuration instruction based on the third mapping relationship. When the conversion configuration instruction meets the conduction condition, send the conversion configuration instruction to the relay assembly. The conversion configuration instruction is used to control the switches of the relays in the relay assembly to conduct the nodes to be used corresponding to each node to be replaced.

[0078] The conversion configuration instruction is a relay conduction instruction generated based on the third mapping relationship.

[0079] Specifically, the relay assembly includes multiple relays. The number of relays is related to the number of node correspondence relationships. After the main control chip determines the third mapping relationship, according to the corresponding relationship between the node to be replaced and the node to be used in the third mapping relationship, it determines the relays that need to be conducted, and generates a corresponding conversion configuration instruction according to the relays that need to be conducted. For example, when the node to be replaced 12 corresponds to the node to be used 6, the main control chip determines according to this corresponding relationship that the relay 8 on the connection line between the node to be replaced 12 and the node to be used 6 needs to be conducted, and the main control chip generates a conversion configuration instruction according to the relay 8.

[0080] The conduction condition is a condition for judging whether the third mapping relationship is correct. When the conversion configuration instruction meets the conduction condition, it means that the corresponding relationship between each node to be replaced and each node to be used is correct at this time, and conversion can be connected; when the conversion configuration instruction does not meet the conduction condition, it means that the corresponding relationship between each node to be replaced and the node to be used is incorrect at this time, and direct connection conversion is not possible.

[0081] Specifically, when the main control chip determines that the conversion configuration instruction meets the conduction condition, it sends the conversion configuration instruction to the relay assembly. The relay assembly controls the corresponding relay to conduct according to the conversion configuration instruction to realize the conversion of the nodes.

[0082] In the above secondary equipment wiring conversion method, by obtaining the first model file of the equipment to be replaced and the second model file of the equipment to be used, the first mapping relationship and the second mapping relationship between each node in the two equipment and the node functions corresponding to each node are determined. Taking the node functions commonly included in the first mapping relationship and the second mapping relationship as a reference, the third mapping relationship between each node of the equipment to be replaced and each node of the equipment to be used can be determined. Based on the third mapping relationship, a conversion configuration instruction is generated, and the switch of the relay in the relay assembly is controlled through the conversion configuration instruction, so as to realize the conduction between each node of the equipment to be replaced and each node on the equipment to be used corresponding to its node function, and realize the conversion of node functions between different old and new equipment nodes. The entire conversion process does not require re-designing the secondary equipment, nor changing the original wiring of the secondary equipment, with lower replacement costs, simple and rapid conversion process, and improved safety and reliability of power grid operation.

[0083] In one embodiment, as Figure 6 shown, when the conversion configuration instruction meets the conduction condition, sending the conversion configuration instruction to the relay assembly includes the following steps:

[0084] Step 602, call the graphical tool to generate the visual configuration of each node to be replaced and each node to be used according to the conversion configuration instruction.

[0085] Among them, the graphical tool is a management tool for generating graphical displays and operations, and is used to generate a visual configuration interface.

[0086] Among them, the meaning of configuration is to configure, set, and arrange, which means that users can complete the software functions they need through a simple way similar to "building blocks", without writing computer programs, and can be regarded as a secondary development process.

[0087] Specifically, the main control chip calls the graphical tool to monitor, control, and manage the corresponding relationship between each node to be replaced and each node to be used according to the conversion configuration instruction, so as to generate the visual configuration of each node to be replaced and each node to be used. The visual configuration can be understood as a visual interface, but this visual interface also has control functions at the same time. Among them, the graphical tool is pre-stored in the data storage system of the main control chip.

[0088] Step 604, send the visual configuration to the display device.

[0089] Specifically, the main control chip sends the generated visual configuration of each node to be replaced and each node to be used to the display device, and shows the configuration interface to users or staff on the display device.

[0090] Step 606: If a confirmation conduction instruction returned by the user is received, it is determined that the conversion configuration instruction meets the conduction condition, and the conversion configuration instruction is sent to the relay assembly.

[0091] Among them, the confirmation conduction instruction is generated by the user or the staff when they determine that there is no error in the corresponding relationship between each node to be replaced and each node to be used based on the visual configuration displayed on the display device. Specifically, when the main control chip receives the confirmation conduction instruction returned by the user based on the display device, it can be considered that the conversion configuration instruction meets the conduction condition. At this time, the main control chip can send the conversion configuration instruction to the relay assembly to control the corresponding relay in the relay assembly to conduct.

[0092] In this embodiment, a graphical tool is called to generate the visual configuration of each node to be replaced and each node to be used, and the visual configuration is displayed to the user and the staff through the display device. When the confirmation conduction instruction returned by the user and the staff is received, the conversion configuration instruction is sent to the relay assembly for relay conduction. After manually verifying that the corresponding relationship between each node to be replaced and each node to be used is correct, conduction is carried out, effectively avoiding the occurrence of node conversion errors caused by blind conduction, and improving the safety and reliability of the power grid operation.

[0093] In one embodiment, if an adjustment instruction returned by the user based on the visual configuration is received, it is determined that the conversion configuration instruction does not meet the conduction condition; in response to the adjustment instruction, the conversion configuration instruction is adjusted based on the adjustment instruction, and the adjusted conversion configuration instruction is used as the conversion configuration instruction and sent to the relay assembly.

[0094] Among them, the adjustment instruction is obtained by the user based on reconfiguring the visual configuration.

[0095] Specifically, when the main control chip generates the third mapping relationship or generates the conversion configuration instruction according to the third mapping relationship, due to various influencing factors, the corresponding relationship between each node to be replaced and each node to be used finally obtained may be incorrect and does not meet the conduction condition. When the user finds that the corresponding relationship between each node to be replaced and each node to be used is incorrect according to the visual configuration displayed on the display device, the corresponding relationship between each node to be replaced and each node to be used can be manually adjusted based on the visual configuration, and an adjustment instruction is generated based on the process of the user's manual adjustment.

[0096] When the main control chip receives the returned adjustment instruction, it responds to the adjustment instruction to adjust the original conversion configuration instruction, and uses the adjusted conversion configuration instruction as the current conversion configuration instruction and sends it to the relay assembly to control the corresponding relay to conduct.

[0097] In this embodiment, the user can interact with the main control chip through the visual configuration displayed on the display device. When there is an error in the corresponding relationship of the nodes, manual intervention and adjustment can be carried out in a timely manner, effectively avoiding the situation of node configuration errors caused by deviations in computer logic, improving the accuracy of node matching, and further enhancing the safety and stability of the power system operation.

[0098] In one embodiment, as Figure 7 shown, the secondary equipment wiring conversion method further includes the following steps:

[0099] Step 702, obtain the on / off information of each relay in the relay assembly.

[0100] Specifically, after the relay assembly responds to the conversion configuration instruction and conducts the corresponding relay, the main control chip obtains the on / off information of each relay in the relay assembly.

[0101] Step 704, perform node matching verification according to the on / off information and the conversion configuration instruction.

[0102] Specifically, the main control chip determines the conducted relays according to the obtained on / off information of each relay in the relay assembly. The conducted relays are subjected to node matching verification with the relays that need to be conducted in the conversion configuration instruction to determine whether there are any omissions or incorrect conduction situations. If there are no omissions or incorrect conduction situations, it is considered that the node matching verification is successful. If there are omissions or incorrect conduction situations, it is considered that the node matching verification fails.

[0103] Step 706, if the verification fails, generate an alarm instruction, send the alarm instruction to the relay assembly, and control the relay assembly to conduct the device alarm node for alarm.

[0104] Specifically, after the main control chip determines that the node matching verification fails, it generates an alarm instruction and sends the alarm instruction to the relay assembly. The alarm instruction is used to control the relay assembly to conduct the alarm relay corresponding to the device alarm node to alarm the user.

[0105] In this embodiment, after determining that the node matching verification fails, an alarm device is controlled to alarm by generating an alarm instruction, reminding the staff to check and adjust the node corresponding relationship of the secondary equipment wiring conversion device, effectively avoiding the situation of node matching errors caused by mistakes in the relay conduction process, improving the accuracy of node matching, and further enhancing the safety and stability of the power system operation.

[0106] In one embodiment, as Figure 8 shown, a secondary equipment wiring conversion method is provided. This method is applied in Figure 4In the secondary equipment wiring conversion device shown, the method specifically includes the following steps:

[0107] First, when the secondary equipment wiring conversion device connects the equipment to be replaced and the equipment to be used, the main control chip obtains the first model file of the equipment to be replaced and the second model file of the equipment to be used. The first model file contains the first mapping relationship between each node to be replaced and the node function in the equipment to be replaced, and the second model file contains the second mapping relationship between each node to be used and the node function in the equipment to be used. According to the first mapping relationship and the second mapping relationship, determine the third mapping relationship between each node to be replaced and each node to be used. Generate a conversion configuration instruction based on the third mapping relationship, call a graphical tool, generate a visual configuration of each node to be replaced and each node to be used according to the conversion configuration instruction, and send the visual configuration to the display device.

[0108] The display device displays the visual configuration to the user. The user initially verifies whether the node correspondence is accurate based on the visual configuration of each node to be replaced and each node to be used. If it is accurate, return a confirmation conduction instruction. If it is not accurate, return an adjustment instruction based on the visual configuration.

[0109] When the main control chip receives the confirmation conduction instruction, it determines that the conversion configuration instruction meets the conduction conditions and sends the conversion configuration instruction to the relay component. When receiving the adjustment instruction returned by the user based on the visual configuration, it determines that the conversion configuration instruction does not meet the conduction conditions; responds to the adjustment instruction, adjusts the conversion configuration instruction based on the adjustment instruction, and uses the adjusted conversion configuration instruction as the conversion configuration instruction and issues it to the relay component.

[0110] The relay component controls the corresponding relay to conduct based on the conversion configuration instruction sent by the main control chip, converts each node to be replaced and each node to be used, so as to realize the replacement between the equipment to be replaced and the equipment to be used.

[0111] After the relay component completes the conduction of the corresponding relay, the main control chip obtains the on-off information of each relay in the relay component at this time, performs node matching verification according to the on-off information and the conversion configuration instruction, and determines whether there is any omission or incorrect conduction. If there is no omission or incorrect conduction, it is considered that the node matching verification is successful. If there is an omission or incorrect conduction, it is considered that the node matching verification fails. If the verification fails, generate an alarm instruction, send the alarm instruction to the relay component, and control the relay component to conduct the alarm node for alarm.

[0112] In the secondary equipment wiring conversion method of this embodiment, a programmable main control chip is used to control the corresponding relationship between the nodes of the equipment to be replaced and the equipment to be used, so as to realize the conversion of the same functions of the nodes on different equipment. Through two verifications, it is determined whether the node connection is correct, which improves the accuracy of node conversion and further improves the safety and stability of the power system operation.
