[0002] With the rapid development of industrial automation and intelligent manufacturing technologies, automated production lines such as semiconductor equipment, lithium battery production lines, and intelligent warehousing generally adopt a distributed IO control architecture that connects remote input / output (IO) terminal blocks and multiple distributed junction boxes in parallel to meet the needs of multi-point, distributed signal acquisition and control of equipment. The convenience of on-site wiring and the stability of signal transmission have become industry requirements.

[0003] The current remote I / O terminal block is pre-configured with a fixed mapping relationship between physical ports and junction boxes. On-site construction personnel complete the junction box connection according to the preset sequence, identify the junction box through hardware identification, and then realize signal distribution and transmission. This solution can meet the basic distributed I / O control functions.

[0004] However, manual wiring on-site is prone to errors in the connection sequence of junction boxes, leading to incorrect signal attribution and equipment malfunction. It also results in difficulties in on-site debugging, low maintenance efficiency, and frequent equipment downtime.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0008] Furthermore, the step of polling each of the junction boxes according to a preset reading time slice to obtain a target identity sequence composed of all the junction boxes includes: Obtain the port number of each of the wiring ports, allocate the reading time slice to each of the wiring ports according to the port number, and control each of the wiring ports to send reading instructions to each of the junction boxes in the order in which each of the wiring ports receives the reading time slice; Receive feedback information returned by each of the junction boxes based on the read command, and extract the identity identifier of each junction box from the feedback information; The target identity sequence is generated based on the identity identifier of each junction box.

[0009] Furthermore, generating the target identity sequence based on the identity identifiers of each of the junction boxes includes: The identification identifiers of each junction box are sorted to obtain an initial identification identifier sequence; The initial identity sequence is detected to obtain detection results, which include identity anomalies and identity normalities. Based on the detection results, the initial identity sequence is updated to obtain the target identity sequence.

[0010] Furthermore, the step of detecting the initial identity sequence to obtain the detection result includes: If any one of the junction box identifiers in the initial identifier sequence does not meet the preset conditions, then the detection result is determined to be that the identifier is abnormal; If all the junction box identifiers in the initial identifier sequence meet the preset conditions, then the detection result is determined to be that the identifier is normal.

[0011] Furthermore, updating the initial identity sequence based on the detection result to obtain the target identity sequence includes: When the detection result indicates that the identity identifier is normal, the initial identity identifier sequence is determined as the target identity identifier sequence; When the detection result indicates that the identity identifier is abnormal, the junction box corresponding to the abnormal identity identifier is identified, a preset temporary identity identifier is assigned to the junction box corresponding to the abnormal identity identifier, and the initial identity identifier sequence is updated according to the temporary identity identifier to obtain the target identity identifier sequence.

[0012] Furthermore, adjusting the current mapping relationship based on multiple standard mapping relationships to obtain the target mapping relationship includes: Based on multiple standard mapping relationships, determine whether the current mapping relationship is an abnormal mapping relationship; If the current mapping relationship is the abnormal mapping relationship, then the abnormal junction box is determined according to the abnormal mapping relationship, and the target wiring port corresponding to the abnormal junction box is determined according to the standard mapping relationship corresponding to the abnormal junction box. Based on the target wiring port corresponding to the abnormal junction box, the abnormal mapping relationship is adjusted to obtain the target mapping relationship.

[0013] Furthermore, after adjusting the current mapping relationship according to multiple standard mapping relationships to obtain a target mapping relationship, so that the wiring port can transmit signals with the junction box based on the target mapping relationship, the method further includes: Monitor the level signal of each of the wiring ports, and determine whether each of the wiring ports and each of the junction boxes is in a disconnected state based on the level signal; If either the connection port or the junction box is in the disconnected state, the target mapping relationship between the connection port and the junction box in the disconnected state will be adjusted to a preset standard mapping relationship.

[0027] It should be noted that the signal transmission method of the IO module provided in this application embodiment is generally executed by the terminal device, and correspondingly, the signal transmission device of the IO module is generally located in the terminal device.

[0028] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0029] Continue to refer to Figure 2 The diagram illustrates a flowchart of an embodiment of a signal transmission method for an I / O module according to this application. The signal transmission method for the I / O module includes the following steps: Step S201: According to the preset reading time slice, each of the junction boxes is polled to obtain the target identity sequence composed of all the junction boxes.

[0030] In this embodiment, the signal transmission method of the IO module operates on an electronic device (e.g., Figure 1 The terminal device shown can send or receive data via wired or wireless connection. It should be noted that the aforementioned wireless connection methods may include, but are not limited to, 3G / 4G / 5G connections, Wi-Fi connections, Bluetooth connections, WiMAX connections, Zigbee connections, UWB (ultra-wide band) connections, and other currently known or future wireless connection methods.

[0031] In this embodiment, the reading time slice refers to the time period during which each junction box of the remote IO terminal block is allocated an independent identity identifier for reading. Each time slice is allocated a uniform fixed duration (which can be 5ms or 10ms), and the duration is sufficient for only one identity identifier (ID) reading and feedback. This avoids communication collisions caused by multiple junction boxes simultaneously feeding back signals, ensuring the stability and uniqueness of identity reading. A junction box refers to a passive extension unit of the remote IO terminal block, carrying identity identifier information, used for nearby connection to industrial sensors to achieve distributed wiring at various points. The target identity identifier sequence refers to the ordered set of all online junction box identity identifiers collected by the terminal block after polling.

[0032] Specifically, the 32-point remote I / O terminal block is installed at the center of the equipment motion control platform. Depending on the type of field sensors, three-wire or two-wire junction boxes are placed near the sensors and at the end of the equipment. The sensor signal and power lines are directly connected to the nearest junction box, eliminating the need for long-distance single-wire cabling. Multi-core cables are used to connect all junction boxes to the terminals of the 32-point remote I / O terminal block, with all junction boxes serving as passive I / O extension units for the terminal block. The remote I / O terminal block allocates an independent and equal-length read time slice to each physical terminal based on its hardware number. These time slices are arranged sequentially by port, without overlap, and an ordered polling read is performed on all junction boxes, ultimately obtaining an initial identity sequence composed of all junction box identifiers. This initial identity sequence is then checked for completeness and validity, and the results are used to update the initial sequence, ultimately yielding a stable and valid target identity sequence.

[0033] Step S202: Determine the current mapping relationship between each of the wiring ports and each of the junction boxes based on the target identity sequence.

[0034] In this embodiment, the current mapping relationship refers to the binding relationship between each physical connection port of the remote IO terminal block and the actual junction box connected to that port on site. The identity identifiers in the target identity identifier sequence are matched sequentially with the connection ports of the same sequence number. The first identity identifier in the sequence corresponds to connection port number one, the second identity identifier corresponds to connection port number two, and so on, completing the matching of all ports and identity identifiers. The resulting port-to-junction box correspondence is the current mapping relationship determined in this process. For example, if the target identity identifier sequence is junction box b, junction box d, junction box c, and junction box a, according to the above matching method, connection port 1 corresponds to junction box b, connection port 2 corresponds to junction box d, connection port 3 corresponds to junction box c, and connection port 4 corresponds to junction box a, ultimately obtaining the complete current mapping relationship.

[0035] Step S203: Obtain the standard mapping relationship between each of the wiring ports and each of the junction boxes.

[0036] In this embodiment, the standard mapping relationship refers to the ideal correspondence between physical connection ports and standard junction box identifiers pre-configured by the remote I / O terminal block before system initialization. For example, the preset standard mapping relationship is as follows: connection port 1 corresponds to junction box a, connection port 2 corresponds to junction box b, connection port 3 corresponds to junction box c, and connection port 4 corresponds to junction box d. This set of correspondences is the recognized correct wiring standard. Under normal wiring conditions, signals will be transmitted between the connection ports and junction boxes based on the standard mapping relationship.

[0037] Step S204: Adjust the current mapping relationship according to the multiple standard mapping relationships to obtain a target mapping relationship, so that the wiring port can transmit signals with the junction box based on the target mapping relationship.

[0038] In this embodiment, the connection ports with the same number in the standard mapping relationship and the current mapping relationship are used as the basis for comparison, and the identification of the junction box corresponding to each port is matched one by one. By comparing and identifying the corresponding deviations in the current mapping relationship, abnormal mapping relationships and corresponding abnormal junction boxes are located. Then, based on the standard mapping relationship, the target connection port corresponding to each abnormal junction box is determined, and the correspondence relationship of the abnormal mapping relationship is adjusted accordingly. The part of the current mapping relationship that is consistent with the standard mapping relationship is retained, and the abnormal part is replaced with the correct relationship corresponding to the standard, and finally a target mapping relationship without deviation is formed. Based on this target mapping relationship, the remote IO terminal block clearly identifies the junction box corresponding to each connection port, thereby realizing normal signal transmission between the connection port and the junction box and avoiding signal error problems caused by incorrect wiring sequence.

[0039] This application polls each junction box using a preset reading time slice, forming a target identification sequence for each junction box and reducing signal interference caused by simultaneous feedback from multiple junction boxes. Then, based on the target identification sequence, the current mapping relationship between the wiring port and the junction box can be determined, intuitively reflecting the actual layout of the wiring on site. Next, the standard mapping relationship between the wiring port and the junction box is obtained, providing a fixed reference standard for correcting wiring relationships. Finally, the current mapping relationship is adjusted based on the standard mapping relationship, correcting mapping deviations caused by incorrect wiring sequence. The formed target mapping relationship allows the wiring port and junction box to transmit signals normally, avoiding signal transmission errors caused by incorrect wiring sequence.

[0040] In some optional implementations of this embodiment, the step of polling each of the junction boxes according to a preset reading time slice to obtain the target identity sequence composed of all the junction boxes includes: Obtain the port number of each of the wiring ports, allocate the reading time slice to each of the wiring ports according to the port number, and control each of the wiring ports to send reading instructions to each of the junction boxes in the order in which each of the wiring ports receives the reading time slice; Receive feedback information returned by each of the junction boxes based on the read command, and extract the identity identifier of each junction box from the feedback information; The target identity sequence is generated based on the identity identifier of each junction box.

[0041] In this embodiment, the port number of each connection port is a unique serial number assigned to each physical connection port by the remote IO terminal block, used to distinguish different connection ports. The identification identifier of the connection box is the unique identification information of the connection box, used to distinguish different connection boxes. Specifically, the terminal block allocates independent and non-overlapping read time slices to each connection port based on the order of the port numbers. The time slices are arranged sequentially according to the port number order. The terminal block sends a read command to the connection box connected to the connection port corresponding to the current time slice within the time period corresponding to the allocated read time slice. After receiving the read command sent by the terminal block within its corresponding read time slice, the connection box generates and returns feedback information to the terminal block according to a preset communication format. The terminal block parses the received feedback information, filters and extracts the identification data specifically used to identify the connection box from the fixed fields of the feedback information, and obtains the identification identifier corresponding to the connection box.

[0042] This application assigns independent reading time slices to each wiring port by port numbering, which avoids signal interference caused by simultaneous feedback from multiple junction boxes. By issuing reading commands and receiving feedback information according to the time slice sequence, stable information exchange between the terminal block and the junction box can be achieved. Extracting identification identifiers and generating sequences from the feedback information provides complete data support for subsequently determining the mapping relationship between the wiring ports and junction boxes.

[0043] In some optional implementations of this embodiment, the step of generating the target identity sequence based on the identity identifiers of each junction box includes: The identification identifiers of each junction box are sorted to obtain an initial identification identifier sequence; The initial identity sequence is detected to obtain detection results, which include identity anomalies and identity normalities. Based on the detection results, the initial identity sequence is updated to obtain the target identity sequence.

[0044] In this embodiment, the terminal block first arranges all extracted junction box identifiers sequentially according to a preset order to form an initial identifier sequence. This preset order can be ascending order based on the physical number of the junction port or the chronological order of the read time slices. The terminal block then performs status checks on all identifiers within the initial identifier sequence to determine if any identifiers are abnormal, obtaining a detection result indicating whether the identifiers are normal or abnormal. Abnormal identifiers may include: multiple junction boxes having identical identifiers (identifier duplication); some junction ports not reporting valid identifiers (identifier missing); incorrect identifier formats from the junction boxes, preventing proper system recognition; or identifier content not matching the system's preset legal encoding range. The terminal block then processes the initial sequence based on the detection results. If the detection result is normal, the initial sequence content is directly used; if the detection result is abnormal, the abnormal identifiers in the sequence are corrected. After sequence optimization, the target identifier sequence is obtained.

[0045] This application sorts the identifiers of the junction boxes to form a regular initial identifier sequence, providing an ordered data foundation for subsequent testing. Performing state checks on the initial sequence can promptly identify any anomalies in the identifiers. Updating the sequence based on the check results can correct these anomalies, ensuring that the generated target identifier sequence meets the usage requirements and guaranteeing the stable progress of subsequent processes.

[0046] In some optional implementations of this embodiment, the step of detecting the initial identity sequence and obtaining the detection result includes: If any one of the junction box identifiers in the initial identifier sequence does not meet the preset conditions, then the detection result is determined to be that the identifier is abnormal; If all the junction box identifiers in the initial identifier sequence meet the preset conditions, then the detection result is determined to be that the identifier is normal.

[0047] In this embodiment, the detection results include abnormal and normal identification identifiers. Abnormal identification identifiers include at least duplicate identifiers, missing identifiers, incorrect identifier formats, and identifiers exceeding a preset valid encoding range. Specifically, the preset condition for duplicate identifiers is that each junction box's identifier is unique in the sequence and appears only once. If an identifier appears more than once in the sequence, it is determined to be an abnormal type of duplicate identifier. The preset condition for missing identifiers is that each junction port returns a valid identifier, and there are no gaps in the sequence. If a junction port returns a gap, it is determined to be an abnormal type of missing identifier. The preset condition for incorrect identifier formats is that the identifier's encoding format completely matches the system's preset parsing format. If there is a mismatch in encoding formats, it is determined to be an abnormal type of incorrect identifier format. If all the junction box identifiers in the initial identifier sequence meet the above preset conditions, the detection result is determined to be that the identification identifier is normal.

[0048] This application detects identity identifiers by setting multiple preset conditions, which can comprehensively identify various anomalies in the sequence and clearly distinguish between normal and abnormal states of identity identifiers. This detection method can intuitively reflect the data quality of the sequence, providing a clear basis for judgment in subsequent sequence update operations and avoiding the impact of identifier issues on the progress of subsequent related processes.

[0049] In some optional implementations of this embodiment, the step of updating the initial identity sequence based on the detection result to obtain the target identity sequence includes: When the detection result indicates that the identity identifier is normal, the initial identity identifier sequence is determined as the target identity identifier sequence; When the detection result indicates that the identity identifier is abnormal, the junction box corresponding to the abnormal identity identifier is identified, a preset temporary identity identifier is assigned to the junction box corresponding to the abnormal identity identifier, and the initial identity identifier sequence is updated according to the temporary identity identifier to obtain the target identity identifier sequence.

[0050] In this embodiment, the temporary identity identifier is a pre-configured backup identifier used to replace any abnormal identifiers in the initial identity identifier sequence, ensuring the integrity and usability of the sequence content. If the result is that the identity identifier is normal, the initial identity identifier sequence is directly determined as the target identity identifier sequence. If the result is that the identity identifier is abnormal, the terminal block first identifies the junction box corresponding to the abnormal identity identifier, assigns a preset temporary identity identifier to the junction box, and then uses the temporary identity identifier to replace the abnormal identity identifier in the initial sequence. After completing the sequence update, the target identity identifier sequence is obtained. For example, if there are abnormalities such as duplicate, missing, or incorrectly formatted identifiers in the initial identity identifier sequence, the terminal block locates the corresponding junction box and assigns a temporary identity identifier, replacing the abnormal content to form the target identity identifier sequence. If the sequence is normal, the initial sequence is directly used.

[0051] This application updates the initial identity sequence based on the detection results, allowing for flexible adjustment of the sequence content according to actual conditions. When the identifier is anomaly-free, directly determining the target sequence simplifies the processing flow. When anomalies exist, replacing the temporary identity identifier eliminates the abnormal content in the sequence, ensuring the generated target sequence remains intact and valid, thus avoiding impact on subsequent mapping relationship determination.

[0052] In some optional implementations of this embodiment, the step of adjusting the current mapping relationship according to multiple standard mapping relationships to obtain the target mapping relationship includes: Based on multiple standard mapping relationships, determine whether the current mapping relationship is an abnormal mapping relationship; If the current mapping relationship is the abnormal mapping relationship, then the abnormal junction box is determined according to the abnormal mapping relationship, and the target wiring port corresponding to the abnormal junction box is determined according to the standard mapping relationship corresponding to the abnormal junction box. Based on the target wiring port corresponding to the abnormal junction box, the abnormal mapping relationship is adjusted to obtain the target mapping relationship.

[0053] In this embodiment, misconnection of junction boxes and junction ports is prone to occur during actual wiring. The terminal block obtains the current mapping relationship formed by the actual wiring on site by reading instructions. This relationship is not a preset standard mapping relationship and cannot be directly matched according to the standard mapping relationship. Therefore, it is necessary to first compare and identify the anomaly, and then adjust and correct it. Here, the standard mapping relationship refers to the preset one-to-one mapping relationship between each junction port and each junction box. That is, junction port 1 corresponds to junction box a, which is a standard mapping relationship. Multiple standard mapping relationships refer to the unique standard mapping relationship between multiple junction ports and their respective junction boxes. Specifically, the terminal block compares the current mapping relationship with multiple preset standard mapping relationships one by one, identifies the ports where the corresponding combination of junction port and junction box is inconsistent, determines the mapping relationship between the junction port and the connected junction box as an abnormal mapping relationship, locates the corresponding abnormal junction box based on the abnormal mapping relationship, and then queries the standard mapping relationship to determine the target junction port corresponding to each abnormal junction box. The terminal block first locates the configuration item corresponding to the abnormal mapping relationship, deletes the current incorrect port binding relationship with the junction box identity, and then re-establishes the binding relationship between the target wiring port corresponding to the abnormal junction box in the standard mapping relationship and the junction box identity. Simultaneously, it updates the internal mapping configuration table to ultimately form the correct target mapping relationship. For example, the standard mapping relationship is: wiring port 1 corresponds to junction box a, port 2 corresponds to junction box b, port 3 corresponds to junction box c, and port 4 corresponds to junction box d. If a field worker makes a wiring error, the terminal block will actually collect the current mapping relationship as: port 1 corresponds to junction box b, port 2 corresponds to junction box d, port 3 corresponds to junction box c, and port 4 corresponds to junction box a. After comparison, the terminal block determines that the binding relationship of ports 1, 2, and 4 is abnormal. It then queries the standard mapping to determine the correct ports for each junction box, modifies the incorrect binding item in the mapping configuration table within the system, correcting it to the correct relationship corresponding to the standard. The target mapping relationship can be obtained without modifying the physical wiring on site.

[0054] This application, by comparing the standard mapping relationship with the current mapping relationship, can quickly identify abnormal wiring correspondences and locate the abnormal junction box and its corresponding correct port. Adjustments can be made by modifying the mapping configuration table within the system, without altering the physical wiring on site. This quickly corrects wiring errors and restores the correct correspondence between ports and junction boxes.

[0055] In some optional implementations of this embodiment, after the step of adjusting the current mapping relationship according to multiple standard mapping relationships to obtain a target mapping relationship, so that the wiring port can transmit signals with the junction box based on the target mapping relationship, the method further includes: Monitor the level signal of each of the wiring ports, and determine whether each of the wiring ports and each of the junction boxes is in a disconnected state based on the level signal; If either the connection port or the junction box is in the disconnected state, the target mapping relationship between the connection port and the junction box in the disconnected state will be adjusted to a preset standard mapping relationship.

[0056] In this embodiment, the voltage level signal reflects the physical connection status between the wiring port and the junction box. Based on a pre-set stable reference voltage level range under the connection status, it determines whether each wiring port and each junction box is in a disconnected state. The terminal block continuously collects the real-time voltage level signal of each wiring port and compares the real-time voltage level with the preset reference voltage level. If the real-time voltage level is stable within the preset reference voltage level, it is determined to be a normal connection. If the real-time voltage level is lower than the preset reference voltage level, it is determined that the wiring port and the corresponding junction box are in a disconnected state. The preset reference voltage level can be DC 5V, and the corresponding stable reference range can be in the range of [4.5, 5.5]. Exceeding the reference range means that the real-time voltage level is less than 4.5V. If a wiring port and junction box are detected to be in a disconnected state, the terminal block readjusts the target mapping relationship between this set of disconnected ports and junction boxes to the preset standard mapping relationship. After the line is disconnected, the original mapping relationship will lose its practical function. Restoring it to the standard mapping relationship allows the wiring port and junction box to be matched directly according to the preset correct mapping relationship when the line is subsequently reconnected.

[0057] This application can promptly determine the connection status between the port and the junction box by monitoring the level signal of the wiring port. If a disconnection is detected, the corresponding mapping relationship will be restored to the standard mapping relationship. When the line is reconnected, the two can be correctly matched to avoid the mapping relationship from becoming chaotic and ensure that subsequent signal transmission can proceed smoothly.

Wherein: The polling module 301 is used to poll each of the junction boxes according to a preset reading time slice to obtain a target identity sequence composed of all the junction boxes; The determining module 302 is used to determine the current mapping relationship between each of the wiring ports and each of the junction boxes based on the target identity sequence; The acquisition module 303 is used to acquire the standard mapping relationship between each of the wiring ports and each of the junction boxes; The adjustment module 304 is used to adjust the current mapping relationship according to multiple standard mapping relationships to obtain a target mapping relationship, so that the wiring port can transmit signals with the junction box based on the target mapping relationship.

[0064] The signal transmission device of the IO module provided in this application polls each junction box through a preset reading time slice, forming a target identification sequence corresponding to the junction box, reducing signal interference caused by simultaneous feedback from multiple junction boxes. Then, based on the target identification sequence, the current mapping relationship between the wiring port and the junction box can be determined, intuitively reflecting the actual layout of the wiring on site. Next, the standard mapping relationship between the wiring port and the junction box is obtained, providing a fixed reference standard for correcting the wiring relationship. Finally, the current mapping relationship is adjusted based on the standard mapping relationship, correcting mapping deviations caused by incorrect wiring sequence. The formed target mapping relationship allows the wiring port and junction box to transmit signals normally, avoiding signal transmission errors caused by incorrect wiring sequence.

[0065] In some optional implementations of this embodiment, the polling module 301 is further configured to: Obtain the port number of each of the wiring ports, allocate the reading time slice to each of the wiring ports according to the port number, and control each of the wiring ports to send reading instructions to each of the junction boxes in the order in which each of the wiring ports receives the reading time slice; Receive feedback information returned by each of the junction boxes based on the read command, and extract the identity identifier of each junction box from the feedback information; The target identity sequence is generated based on the identity identifier of each junction box.

[0066] The signal transmission device for the IO module provided in this application allocates independent reading time slices to each wiring port through port numbering, which can avoid signal interference caused by simultaneous feedback from multiple junction boxes. By issuing reading commands and receiving feedback information according to the time slice sequence, information exchange between the terminal block and the junction box can be stably completed. Extracting identification identifiers and generating sequences from the feedback information provides complete data support for subsequently determining the mapping relationship between the wiring ports and junction boxes.

[0067] In some optional implementations of this embodiment, the polling module 301 is further configured to: The identification identifiers of each junction box are sorted to obtain an initial identification identifier sequence; The initial identity sequence is detected to obtain detection results, which include identity anomalies and identity normalities. Based on the detection results, the initial identity sequence is updated to obtain the target identity sequence.

[0068] The signal transmission device for the IO module provided in this application can form a regular initial identifier sequence by sorting the identifiers of the junction box, providing an orderly data foundation for subsequent detection work. Performing status detection on the initial sequence can promptly identify any anomalies in the identifiers, and updating the sequence based on the detection results can correct these anomalies, ensuring that the generated target identifier sequence meets the usage conditions and guaranteeing the stable progress of subsequent processes.

[0069] In some optional implementations of this embodiment, the polling module 301 is further configured to: If any one of the junction box identifiers in the initial identifier sequence does not meet the preset conditions, then the detection result is determined to be that the identifier is abnormal; If all the junction box identifiers in the initial identifier sequence meet the preset conditions, then the detection result is determined to be that the identifier is normal.

[0070] The signal transmission device of the IO module provided in this application can detect identity identifiers by setting multiple preset conditions, comprehensively identifying various abnormal situations in the sequence and clearly distinguishing between normal and abnormal states of identity identifiers. This detection method can intuitively reflect the data quality of the sequence, providing a clear basis for judgment for subsequent sequence update operations and avoiding the impact of identifier problems on the progress of subsequent related processes.

[0071] In some optional implementations of this embodiment, the polling module 301 is further configured to: When the detection result indicates that the identity identifier is normal, the initial identity identifier sequence is determined as the target identity identifier sequence; When the detection result indicates that the identity identifier is abnormal, the junction box corresponding to the abnormal identity identifier is identified, a preset temporary identity identifier is assigned to the junction box corresponding to the abnormal identity identifier, and the initial identity identifier sequence is updated according to the temporary identity identifier to obtain the target identity identifier sequence.

[0072] The signal transmission device of the IO module provided in this application can flexibly adjust the sequence content according to the actual situation by updating the initial identity sequence based on the detection results. When there is no abnormality in the identifier, the target sequence can be directly determined, which simplifies the processing flow. When there is an abnormality in the identifier, the abnormal content in the sequence can be eliminated by replacing the temporary identity, so that the generated target sequence remains complete and valid, and avoids affecting the determination of subsequent mapping relationships.

[0073] In some optional implementations of this embodiment, the adjustment module 304 is further configured to: Based on multiple standard mapping relationships, determine whether the current mapping relationship is an abnormal mapping relationship; If the current mapping relationship is the abnormal mapping relationship, then the abnormal junction box is determined according to the abnormal mapping relationship, and the target wiring port corresponding to the abnormal junction box is determined according to the standard mapping relationship corresponding to the abnormal junction box. Based on the target wiring port corresponding to the abnormal junction box, the abnormal mapping relationship is adjusted to obtain the target mapping relationship.

[0074] The signal transmission device for the IO module provided in this application can quickly identify abnormal wiring correspondences by comparing the standard mapping relationship with the current mapping relationship, and locate the abnormal junction box and its corresponding correct port. Adjustments can be made by modifying the mapping configuration table within the system, without altering the physical wiring on site. This allows for rapid correction of wiring errors and restores the correct correspondence between ports and junction boxes.

[0075] In some optional implementations of this embodiment, the adjustment module 304 is further configured to: Monitor the level signal of each of the wiring ports, and determine whether each of the wiring ports and each of the junction boxes is in a disconnected state based on the level signal; If either the connection port or the junction box is in the disconnected state, the target mapping relationship between the connection port and the junction box in the disconnected state will be adjusted to a preset standard mapping relationship.

[0076] The signal transmission device of the IO module provided in this application can promptly determine the connection status between the port and the junction box by monitoring the level signal of the wiring port. After detecting a disconnection, it restores the corresponding mapping relationship to the standard mapping relationship, so that the two can be correctly matched when the line is reconnected, avoiding the mapping relationship from becoming chaotic and ensuring that subsequent signal transmission can proceed smoothly.
