[0045] In one embodiment, Figure 1 As shown, a terminal block wiring detection system is provided, and the system includes a detection device 100, a first row of needles 200 and a second row of needles 300.

[0046] The number of the first pins of the first pin row 200 and the number of the second pins of the second pin row 300 are both the first number; for example, the number of the first pins of the first pin row 200 and the number of the second pins of the second pin row 300 are both twelve.

[0047] The spacing between the pins of the pin row (including the first pin row 200 and the second pin row 300 ) is determined according to the spacing between the terminal pairs of the terminal row.

[0048] like Figure 2 Shown is another schematic diagram of the terminal block wiring detection system.

[0049] See also Figure 2 In this embodiment, the detection device 100 includes a first number of relays. For example, assuming that both the first row of pins and the second row of pins have twelve pins, the detection device includes twelve relays.

[0050] Each relay has a pair of normally open contacts and a pair of normally closed contacts.

[0051] Among them, a pair of normally open contacts includes two normally open contacts, and a pair of normally closed contacts includes two normally closed contacts. Figure 2 Taking relay 1 as an example, relay 1 has normally open contact 1_1, normally open contact 1_2, normally closed contact 1_1 and normally closed contact 1_2; taking relay 2 as an example, relay 1 has normally open contact 2_1, normally open contact 2_2, normally closed contact 2_1 and normally closed contact 2_2.

[0052] Each relay is connected to a first pin in the first row of pins 200 and a second pin in the second row of pins 300 through each normally open contact of the relay. Figure 2 Taking relay 1 as an example, relay 1 is connected to the first pin 1 of the first row of pins 200 through the normally open contact 1_1, and relay 1 is connected to the second pin 1 of the second row of pins 300 through the normally open contact 1_2; taking relay 2 as an example, relay 2 is connected to the first pin 2 of the first row of pins 200 through the normally open contact 2_1, and relay 2 is connected to the second pin 2 of the second row of pins 300 through the normally open contact 2_2.

[0053] The order of the first pin and the second pin connected to each relay in the first row of pins 200 and the second row of pins 300 is the same as the order of the relay in the plurality of relays. Figure 2Taking the first relay among the multiple relays, relay 1, as an example, the first pin connected to relay 1 is ranked first in the first row of pins 200, that is, first pin 1, and the second pin connected to relay 1 is also ranked first in the second row of pins 300, that is, second pin 1; taking the second relay among the multiple relays, relay 2, as an example, the first pin connected to relay 2 is ranked second in the first row of pins 200, that is, first pin 2, and the second pin connected to relay 2 is also ranked second in the second row of pins 300, that is, second pin 2.

[0054] In this embodiment, the first row of needles 200 and the second row of needles 300 are used to connect to each pair of terminals to be tested of the terminal row to be tested through each first pin and each second pin respectively.

[0055] There are multiple terminal pairs on the terminal block to be tested, and the terminal pairs to be tested may be all terminal pairs on the terminal block to be tested, or may be part of the terminal pairs on the terminal block to be tested.

[0056] Wherein, each first pin and each second pin are connected to each terminal pair to be tested by being inserted into each terminal pair to be tested.

[0057] The first row of needles 200 and the second row of needles 300 correspond to the positive electrode and the negative electrode, respectively. Taking the case where the first row of needles 200 corresponds to the positive electrode and the second row of needles 300 corresponds to the negative electrode as an example, the first row of needles 200 is inserted into the positive terminal pair in each terminal pair to be tested through each first pin and connected to each positive terminal pair, and the second row of needles 300 is inserted into the negative terminal pair in each terminal pair to be tested through each second pin and connected to each negative terminal pair.

[0058] In actual applications, the pins corresponding to the positive pole are red, and the pins corresponding to the negative pole are black.

[0059] The order of the first pin and the second pin connected to each terminal pair to be tested in the first pin row 200 and the second pin row 300 is the same as the order of the terminal pairs to be tested in each terminal pair to be tested. Figure 2 , the first pin connected to the terminal pair to be tested is ranked first in the first row of pins 200, i.e., first pin 1, and the second pin connected to the terminal pair to be tested is also ranked first in the second row of pins 300, i.e., second pin 1; taking the second terminal pair to be tested, i.e., terminal pair 2 to be tested, among the terminal pairs to be tested, as an example, refer to Figure 2 The first pin connected to the terminal pair to be tested is ranked second in the first row of pins 200 , namely, first pin 2 , and the second pin connected to the terminal pair to be tested is also ranked second in the second row of pins 300 , namely, second pin 2 .

[0060] In this embodiment, the detection device 100 is used to control the opening and closing of each normally open contact and each normally closed contact of each relay when a terminal block wiring detection request is received, and based on the contact opening and closing control of each relay, perform wiring detection on each terminal pair to be tested in turn to obtain the connection status of each terminal pair to be tested.

[0061] The connection status of the terminal pair is used to indicate whether the two corresponding terminals are connected. The connection status is divided into connected and disconnected.

[0062] In a specific application, the detection device 100 further includes a relay switching module, and the relay switching module is used to control the opening and closing of contacts of each relay.

[0063] In a specific application, the detection device 100 also includes a measurement module, which is used to obtain the circuit conductivity of the target terminal pair in each terminal pair to be tested through the contact opening and closing control of the relay switching module, and determine the connection state of the target terminal pair according to the circuit conductivity of the target terminal pair; specifically, if the circuit of the target terminal pair is conductive, the connection state of the target terminal pair is connected, and if the circuit of the target terminal pair is not conductive, the connection state of the target terminal pair is disconnected. Among them, the target terminal pair is the terminal pair to be tested that is undergoing wiring detection among the terminal pairs to be tested.

[0064] In a specific application, the detection device 100 further includes an input module, and the detection personnel send a terminal block wiring detection request to the detection device through the input module; in actual application, the input module is an industrial control touch screen.

[0065] The working principle of the terminal block wiring detection system provided in this embodiment is described below:

[0066] Specifically, when the inspector needs to inspect the wiring conditions of each terminal pair to be tested in the terminal row to be tested, the inspector first inserts the first row of needles 200 and the second row of needles 300 in the terminal row wiring inspection system into each terminal pair to be tested; taking the first row of needles 100 corresponding to the positive pole and the second row of needles 200 corresponding to the negative pole as an example, the specific operation is to take the first first pin of the first row of needles 200 as the starting point, insert the first pins of the first row of needles 200 into the positive terminal of each terminal pair to be tested in sequence, and take the first second pin of the second row of needles 300 as the starting point, insert the second pins of the second row of needles into the negative terminal of each terminal pair to be tested in sequence.

[0067] Then, the inspector initiates a terminal block wiring detection request to the detection device 100 through the input module of the detection device 100 in the terminal block wiring detection system; the detection device 100 responds to the terminal block wiring detection request, controls the contact opening and closing of each normally open contact and each normally closed contact of each relay in the detection device 100, and automatically performs wiring detection on each terminal pair to be tested in turn through the contact opening and closing control, thereby determining whether each terminal pair to be tested is connected or disconnected in one wiring detection.

[0068] In the above-mentioned terminal block wiring detection system, each relay is connected to a first pin in the first row of needles and a second pin in the second row of needles through each normally open contact in the corresponding normally open contact pair, and the first row of needles and the second row of needles are connected to each pair of terminals to be tested of the terminal block to be tested through each first pin and each second pin, respectively. In this way, the terminal block wiring detection system can control the opening and closing of the normally open contact pairs and the normally closed contact pairs of each relay based on the detection device, and detect each pair of terminals to be tested in turn in one wiring detection to obtain the connection status of each pair of terminals to be tested. Compared with the one-by-one detection based on the multimeter, the above-mentioned terminal block wiring detection system improves the detection efficiency.

[0069] In an exemplary embodiment, the detection device 100 is also used to control the closing of each normally open contact of the target relay corresponding to the target terminal pair in each terminal pair to be tested, control the opening of each normally closed contact of the target relay, control the opening of each normally open contact of each relay except the target relay, and control the closing of each normally closed contact of the remaining relays to obtain the connection state with the target terminal pair.

[0070] The target terminal pair is a terminal pair to be tested that is undergoing wiring detection among multiple terminal pairs to be tested; the target relay is a relay among multiple relays that is connected to the same first pin and the same second pin as the target terminal pair.

[0071] Specifically, the detection device 100 performs wiring detection on each terminal pair to be tested in turn; for each terminal pair to be tested that is undergoing wiring detection, the detection device 100 first determines the terminal pair to be tested as a target terminal pair, and determines the relay connected to the same first pin and the same second pin as the target terminal pair among multiple relays as the target relay; then, the detection device 100 controls the two normally open contacts of the target relay to be closed, and controls the two normally closed contacts of the target relay to be disconnected, and at the same time, controls the two normally open contacts of each remaining relay to be disconnected, and controls the two normally closed contacts of each remaining relay to be closed, thereby obtaining the connection state of the target terminal pair. Among them, the remaining relays are each relay except the target relay among the relays.

[0072] For an example, see Figure 2, taking the target terminal pair as the first group of target terminal pairs as an example, the target relay is relay 1, and the detection device 100 controls the normally open contact 1_1 and the normally open contact 1_2 of relay 1 to be closed, and controls the normally closed contact 1_1 and the normally closed contact 1_2 of relay 1 to be disconnected; the detection device 100 controls the normally open contact 2_1 and the normally open contact 2_2 of relay 2 to be disconnected, and controls the normally closed contact 2_1 and the normally closed contact 2_2 of relay 2 to be closed (the contact closure control of the remaining relays is similar to that of relay 2).

[0073] For another example, see Figure 2 , taking the target terminal pair as the second group of target terminal pairs as an example, the target relay is relay 2, the detection device 100 controls the normally open contact 2_1 and the normally open contact 2_2 of relay 2 to be closed, and controls the normally closed contact 2_1 and the normally closed contact 2_2 of relay 2 to be disconnected; the detection device 100 controls the normally open contact 1_1 and the normally open contact 1_2 of relay 1 to be disconnected, and controls the normally closed contact 11 and the normally closed contact 1_2 of relay 1 to be closed (the contact closure control of the other relays is similar to that of relay 1).

[0074] In this embodiment, the detection device can perform wiring detection on one group of terminal pairs to be tested at a time by controlling the normally open contacts of the target relay to close and the normally closed contacts to open, and controlling the normally open contacts of the remaining relays to open and the normally closed contacts to close, thereby realizing sequential wiring detection of each terminal pair to be tested.

[0075] In an exemplary embodiment, the detection device 100 stores reference connection information of a plurality of terminal blocks.

[0076] The reference connection information of each terminal row is used to record the reference connection status of each terminal pair of the terminal row.

[0077] The reference connection state of each terminal pair is the correct connection state of the terminal pair, for example, the terminal pair should originally be connected or disconnected.

[0078] The terminal row to be tested is any one of the multiple terminal rows.

[0079] In a specific application, the detection device 100 further includes a memory, and the detection device 100 stores the reference connection information through the memory.

[0080] In this embodiment, the detection device 100 is also used to issue a warning message when the connection state of the target terminal pair is different from the reference connection state of the target terminal pair, and when receiving a continue detection instruction, determine the next terminal pair to be tested among the terminal pairs to be tested as a new target terminal pair.

[0081] Specifically, the detection device 100 issues a warning message for a target terminal pair when the connection state of the target terminal pair detected is different from the reference connection state of the stored target terminal pair, for example, the connection state detected is disconnected, but the stored reference connection state is connected, or the connection state detected is connected, but the stored reference connection state is disconnected.

[0082] In response to the warning information, the inspector may determine the target terminal pair as an abnormal terminal pair and record it, or verify the actual connection status of the abnormal terminal pair, and then send a continue detection instruction to the detection device 100 when it is necessary to continue wiring detection on the next terminal pair to be tested.

[0083] In response to the continue detection instruction, the detection device 100 automatically determines the next terminal pair to be tested among the terminal pairs to be tested as a new target terminal pair, and then continues to perform a new round of contact opening and closing control on each relay to obtain the connection status of the new target terminal pair.

[0084] In a specific application, if the input module of the detection device 100 is an industrial control touch screen, the detection device 100 can issue a warning message through the industrial control touch screen.

[0085] In a specific application, the detection personnel sends a continue detection instruction to the detection device 100 through the input module of the detection device 100 .

[0086] See also Figure 2 , for example, assuming that the target terminal pair is the first terminal pair to be tested, the detection device 100 first controls the two normally open contacts of relay 1 to close and the two normally closed contacts to disconnect, controls the two normally open contacts of the remaining relays to disconnect, and the normally closed contacts to close. If the connection state of the first terminal pair to be tested is different from the reference connection state, the detection device 100 issues a warning message; after the detection device 100 issues the warning message, if it receives a continue detection instruction, it automatically determines the second terminal pair to be tested as a new target terminal pair, and controls the two normally open contacts of relay 2 to close and the two normally closed contacts to disconnect, controls the two normally open contacts of relay 1 to disconnect, and the normally closed contact to close, and controls the opening and closing states of the normally open contacts and normally closed contacts of the remaining relays to remain unchanged.

[0087] In this embodiment, the detection device 100 is further configured to determine the next terminal pair to be tested of the target terminal pair among the terminal pairs to be tested as a new target terminal pair when the connection state of the target terminal pair is the same as the reference connection state of the target terminal pair.

[0088] Specifically, the detection device 100 detects that the connection state of the target terminal pair is the same as the reference connection state of the stored target terminal pair, for example, the connection state detected and the stored reference connection state are both connected, or the connection state detected and the stored reference connection state are both disconnected, the detection device 100 automatically determines the next terminal pair to be tested among the terminal pairs to be tested as the new target terminal pair, and then continues to perform a new round of contact opening and closing control on each relay to obtain the connection state of the new target terminal pair.

[0089] For example, assuming that the target terminal pair is the first terminal pair to be tested, the detection device 100 first controls the two normally open contacts of relay 1 to close and the two normally closed contacts to disconnect, and controls the two normally open contacts of the remaining relays to disconnect and the normally closed contacts to close. If the connection state of the first terminal pair to be tested is the same as the reference connection state, the detection device 100 automatically determines the second terminal pair to be tested as the new target terminal pair, and controls the two normally open contacts of relay 2 to close and the two normally closed contacts to disconnect, controls the two normally open contacts of relay 1 to disconnect and the normally closed contact to close, and controls the opening and closing states of the normally open contacts and normally closed contacts of the remaining relays to remain unchanged.

[0090] In this embodiment, the detection device can determine whether the connection state of the target terminal pair detected meets the requirements based on the reference connection state, and by automatically determining the next terminal pair to be tested as the new target terminal pair, it can achieve switching between different terminal pairs to be tested, and then can perform wiring detection on each terminal pair to be tested in turn.

[0091] In an exemplary embodiment, the reference connection status of each terminal pair is stored according to the order of each terminal pair.

[0092] In this embodiment, the detection device 100 is further configured to sequentially determine the reference connection status of each terminal pair to be tested from the stored reference connection information based on the terminal pair identifier and the first quantity carried in the terminal block wiring detection request.

[0093] The terminal pair identifier is an identifier of the first group of terminal pairs to be tested among the terminal pairs to be tested.

[0094] Specifically, when the inspection personnel sends a terminal block wiring inspection request to the inspection device 100, the identification of the first group of terminal pairs to be tested in each terminal pair to be tested can be carried in the terminal block wiring inspection request and sent to inform the inspection device 100 of the first group of terminal pairs to be tested in each terminal pair to be tested for wiring inspection this time; the inspection device 100 receives the terminal block wiring inspection request and parses it to obtain the terminal pair identification carried by the terminal block wiring inspection request, and the terminal pair identification is the identification of the first group of terminal pairs to be tested in each terminal pair to be tested; therefore, the inspection device 100, based on the terminal pair identification and the first quantity, sequentially retrieves the reference connection status of each group of terminal pairs to be tested from the stored reference connection information.

[0095] For example, assuming that the first group of terminal pairs to be tested in each terminal pair to be tested is identified as 0100 and the first number is 12; the detection device 100 sequentially retrieves the reference connection states of the corresponding terminal pairs to be tested identified as 0100 to 0111 from the stored reference connection information.

[0096] In specific applications, multiple terminal blocks can be distributed in different cabinets. Therefore, the inspector can also carry the identifier of the cabinet to which the terminal block to be tested belongs in the terminal block wiring detection request when sending a terminal block wiring detection request to the detection device 100; the detection device 100 parses the terminal block wiring detection request to obtain the cabinet identifier and the terminal pair identifier carried by the terminal block wiring detection request, and the detection device 100 takes out the reference connection status of each group of terminal pairs to be tested from the stored reference connection information based on the cabinet identifier, the terminal pair identifier and the first quantity.

[0097] In this embodiment, the terminal block wiring detection request carries the identifier of the first group of terminal pairs to be tested in each terminal pair to be tested. Based on the terminal pair identifier and the first quantity carried by the terminal block wiring detection request, the detection device can determine the reference connection status of each terminal pair to be tested in turn from the stored reference connection information.

[0098] In an exemplary embodiment, the detection device 100 further includes an audible and visual alarm component.

[0099] In this embodiment, the detection device 100 is used to issue warning information through an audible and visual alarm component.

[0100] In this embodiment, the warning information is sound and light warning information.

[0101] In this embodiment, the detection device sends out sound and light warning information through the sound and light alarm component, which can quickly remind the detection personnel that the connection state of the terminal pair to be tested currently undergoing wiring detection does not match the reference connection state and there is an abnormality.

[0102] In an exemplary embodiment, the detection device 100 is further configured to store the connection status of each terminal pair to be tested.

[0103] Specifically, after obtaining the connection status of each terminal pair to be tested, the detection device 100 saves the connection status of each terminal pair to be tested, so as to determine whether it is caused by human error or external factors when an accident of protection malfunction caused by the terminal pair.

[0104] In this embodiment, the detection device can record the detection result of each wiring detection by saving the connection status of each terminal pair to be tested, thereby providing a reference for subsequent operation and maintenance.

[0105] Based on the same inventive concept, an embodiment of the present application also provides a terminal block wiring detection method applied to the above-mentioned terminal block wiring detection system. Therefore, the specific limitations in one or more terminal block wiring detection method embodiments provided below can refer to the above limitations on the terminal block wiring detection system and will not be repeated here.

[0106] In an exemplary embodiment, the detection device 100 further includes a battery power supply module, and the battery power supply module is used to supply power to the input module, the measurement module, the relay switching module, the sound and light alarm module and the memory in the detection device 100 .

[0107] Each module in the above detection device can be implemented in whole or in part by software, hardware, or a combination thereof. Each module can be embedded in or independent of the processor in the detection device in the form of hardware, or can be stored in the memory in the detection device in the form of software, so that the processor can call and execute the operations corresponding to each module above.

[0108] In one embodiment, Figure 3 As shown, a terminal block wiring detection method is provided. In this embodiment, the method is applied to Figure 1 The terminal block wiring detection system shown in FIG. 1 is used as an example for description. In this embodiment, the method includes the following steps S302 to S304:

[0109] Step S302: upon receiving a terminal block wiring detection request, performing contact opening and closing control on each normally open contact and each normally closed contact of each relay.

[0110] Step S304 , by controlling the opening and closing of the contacts of each relay, the wiring detection is performed on each terminal pair to be tested in turn to obtain the connection status of each terminal pair to be tested.

[0111] Specifically, first, when the inspection personnel need to inspect the wiring conditions of each terminal pair to be tested in the terminal row to be tested, they first insert the first row of needles and the second row of needles in the terminal row wiring inspection system into each terminal pair to be tested; taking the first row of needles corresponding to the positive pole and the second row of needles corresponding to the negative pole as an example, the specific operation is to take the first first pin of the first row of needles as the starting point, and insert the first pins of the first row of needles into the positive terminals of each terminal pair to be tested in turn; taking the first second pin of the second row of needles as the starting point, and inserting the second pins of the second row of needles into the negative terminals of each terminal pair to be tested in turn.

[0112] Then, the inspector initiates a terminal block wiring detection request to the detection device in the terminal block wiring detection system; the detection device responds to the terminal block wiring detection request, controls the contact opening and closing of each normally open contact and each normally closed contact of each relay in the detection device, and automatically performs wiring detection on each terminal pair to be tested in turn through the contact opening and closing control, thereby determining whether each terminal pair to be tested is connected or disconnected in one wiring detection.

[0113] The terminal block wiring detection method and the terminal block wiring detection system are based on the detection device controlling the opening and closing of the normally open contact pairs and the normally closed contact pairs of each relay, and can detect each terminal pair to be tested in turn in one wiring detection to obtain the connection status of each terminal pair to be tested; the terminal block wiring detection method improves the detection efficiency compared with the one-by-one detection based on the multimeter.

[0114] In an exemplary embodiment, in the above step S302, the normally open contacts and the normally closed contacts of each relay are controlled to open and close, specifically including the following contents: for the target terminal pair in each terminal pair to be tested, the normally open contacts of the target relay corresponding to the target terminal pair are controlled to close, the normally closed contacts of the target relay are controlled to open, the normally open contacts of the remaining relays except the target relay are controlled to open, and the normally closed contacts of the remaining relays are controlled to close.

[0115] The target terminal pair is a terminal pair to be tested that is undergoing wiring detection among multiple terminal pairs to be tested; the target relay is a relay among multiple relays that is connected to the same first pin and the same second pin as the target terminal pair.

[0116] The above step S304, by controlling the opening and closing of the contacts of each relay, sequentially performs wiring detection on each terminal pair to be tested to obtain the connection status of each terminal pair to be tested, specifically includes the following contents:

[0117] Based on the contact opening and closing control of the target relay and other relays, the target terminal pair is wired and detected to obtain the connection status of the target terminal pair.

[0118] Specifically, for each terminal pair to be tested that is undergoing wiring detection, the detection device first determines the terminal pair to be tested as a target terminal pair, and determines the relay connected to the same first pin and the same second pin as the target terminal pair among multiple relays as the target relay; then, the detection device controls the two normally open contacts of the target relay to be closed, and controls the two normally closed contacts of the target relay to be disconnected, and at the same time, controls the two normally open contacts of each of the remaining relays to be disconnected, and controls the two normally closed contacts of each of the remaining relays to be closed, thereby obtaining the connection state of the target terminal pair. Among them, the remaining relays are each relay except the target relay among the relays.

[0119] In this embodiment, the detection device can perform wiring detection on one group of terminal pairs to be tested at a time by controlling the normally open contacts of the target relay to close and the normally closed contacts to open, and controlling the normally open contacts of the remaining relays to open and the normally closed contacts to close, thereby realizing sequential wiring detection of each terminal pair to be tested.

[0120] In an exemplary embodiment, after obtaining the connection status of the target terminal pair, the following contents are specifically included: when the connection status of the target terminal pair is different from the reference connection status of the target terminal pair, a warning message is issued; when a continue detection instruction is received, the next terminal pair to be tested of the target terminal pair among the terminal pairs to be tested is determined as a new target terminal pair, and the steps of controlling the closing of each normally open contact of the target relay corresponding to the target terminal pair, controlling the opening of each normally closed contact of the target relay, controlling the opening of each normally open contact of each relay except the target relay, and controlling the closing of each normally closed contact of the remaining relays are returned.

[0121] Specifically, the detection device issues a warning message for a target terminal pair when the connection state of the target terminal pair detected is different from the reference connection state of the stored target terminal pair, for example, the connection state detected is disconnected, but the stored reference connection state is connected, or the connection state detected is connected, but the stored reference connection state is disconnected.

[0122] In response to the warning information, the inspector may determine the target terminal pair as an abnormal terminal pair and record it, or verify the actual connection status of the abnormal terminal pair, and then send a continue detection instruction to the detection device when it is necessary to continue wiring detection on the next terminal pair to be tested.

[0123] In response to the continue detection instruction, the detection device automatically determines the next terminal pair to be tested of the target terminal pair among the terminal pairs to be tested as the new target terminal pair, and then continues to perform a new round of contact opening and closing control on each relay to obtain the connection state of the new target terminal pair.

[0124] In this embodiment, the detection device can determine whether the connection state of the target terminal pair detected meets the requirements based on the reference connection state, and by automatically determining the next terminal pair to be tested as the new target terminal pair, it can achieve switching between different terminal pairs to be tested, and then can perform wiring detection on each terminal pair to be tested in turn.

[0125] In an exemplary embodiment, after obtaining the connection state of the target terminal pair, the following contents are specifically included: when the connection state of the target terminal pair is the same as the reference connection state of the target terminal pair, the next terminal pair to be tested among the terminal pairs to be tested of the target terminal pair is determined as a new target terminal pair, and the steps of controlling the normally open contacts of the target relay corresponding to the target terminal pair to close, controlling the normally closed contacts of the target relay to open, controlling the normally open contacts of the remaining relays except the target relay to open, and controlling the normally closed contacts of the remaining relays to close are returned.

[0126] Specifically, for a target terminal pair, when the connection state of the target terminal pair detected by the detection device is the same as the reference connection state of the stored target terminal pair, for example, the connection state detected and the stored reference connection state are both connected, or the connection state detected and the stored reference connection state are both disconnected, the detection device automatically determines the next terminal pair to be tested among the terminal pairs to be tested as a new target terminal pair, and then continues to perform a new round of contact opening and closing control on each relay to obtain a new connection state of the target terminal pair.

[0127] In this embodiment, the detection device can determine whether the connection state of the target terminal pair detected meets the requirements based on the reference connection state, and by automatically determining the next terminal pair to be tested as the new target terminal pair, it can achieve switching between different terminal pairs to be tested, and then can perform wiring detection on each terminal pair to be tested in turn.

[0128] In order to more clearly illustrate the terminal block wiring detection system and method provided in the embodiment of the present application, the terminal block wiring detection system and method provided in the embodiment of the present application are specifically described in a specific embodiment below, but it should be understood that the embodiment of the present application is not limited thereto. In one exemplary embodiment, the present application also provides a terminal block wiring intelligent detection system and method, which specifically includes the following contents:

[0129] The terminal block wiring intelligent detection system provided in this application is as follows Figure 1 and Figure 2 As shown, the number of pins of the pin header is the same as the number of relays in the system detection device.

[0130] The terminal block wiring intelligent detection method provided in the present application comprises the following steps:

[0131] 1. Before performing secondary circuit maintenance operations, the inspector shall import the correct connection information of the secondary circuit terminal block into the memory of the inspection device in advance.

[0132] 2. The inspector selects the cabinet number and terminal number (the number of the first terminal pair to be tested) on the industrial control touch screen of the testing device to retrieve the correct connection information.

[0133] 3. The inspector fixes the pin header and terminal block.

[0134] 4. The relay switching module in the detection device starts from the first relay and the first terminal pair, closes the normally open contact pair of the current relay, disconnects the normally closed contact pair of the current relay, disconnects the normally open contact pairs of the remaining relays, closes the normally closed contact pairs of the remaining relays, and measures the connection status of the current terminal pair.

[0135] 5. If the connection status of the current terminal pair is consistent with the correct connection information, the relay switching module switches between the relays, closes the normally open contact pair of the next relay, disconnects the normally closed contact pair of the next relay, disconnects the normally open contact pairs of the remaining relays, closes the normally closed contact pairs of the remaining relays, and measures the connection status of the next terminal pair; if the connection status of the current terminal pair is inconsistent with the correct connection information, an audible and visual alarm message is issued to prompt the inspection personnel to check the current terminal pair; the relay switching module switches the relays, closes the normally open contact pair of the next relay, disconnects the normally closed contact pair of the next relay, disconnects the normally open contact pairs of the remaining relays, closes the normally closed contact pairs of the remaining relays, and measures the connection status of the next terminal pair... and repeats this process until all terminal pairs to be tested are inspected.

[0136] 6. All the terminal pairs to be tested have been tested, and the testing device saves the test results of each terminal pair to be tested. The tester can continue to select the cabinet number and terminal number on the industrial control touch screen.

[0137] In this embodiment, first, the switching of the measured terminal pair is completed by the relay switching module inside the detection device, without manual operation, and batch detection can be automatically realized, saving manpower. Secondly, by entering the correct connection information of the secondary circuit terminal block, the measured on-off status can be compared with the entered correct connection status during the measurement process to realize intelligent diagnosis and identification, and judge whether the connection is correct without manual verification and judgment, reducing the possibility of misjudgment. Thirdly, after maintenance or daily operations, a secondary circuit terminal block status database can be synchronously established to record the terminal block connection status information, providing data support for subsequent fault or accident tracing.
