[0025] like Figure 1 and Figure 2As shown, an embodiment of the first aspect of the present application provides a measurement and control system 1000, comprising: at least one functional module 10, a system signal integration box 20 and a measurement and control system cabinet 30. The measurement and control system 1000 can be a modular integrated system for an industrial automation system, used for the acquisition, transmission, processing and control of measurement and control signals. The measurement and control system 1000 can centrally manage and standardize the measurement and control signals scattered on site, and provide an efficient and reliable signal interface. The measurement and control system 1000 connects at least one functional module 10, the system signal integration box 20 and the measurement and control system cabinet 30 through a loop. The measurement and control system 1000 can be applied to industrial scenarios in multiple fields, such as: nuclear power field, petrochemical field, intelligent manufacturing field, etc.

[0026] Functional module 10 can be a skid-mounted box structure within the circuit, with independent modular functions, such as a water control module and a pressure control module. The skid-like design of functional module 10 facilitates independent installation and maintenance. Functional module 10 can integrate working equipment (such as power equipment, fluid control equipment, piping components, etc.) and measurement and control components 102. Measurement and control components 102 can include sensors and instruments (such as flow meters, pressure sensors, temperature sensors, and liquid level sensors), which can collect real-time operating parameters of these working units. Due to the complexity of industrial scenarios, measurement and control system 1000 is typically configured with multiple functional modules 10.

[0027] The system signal integration box 20 serves as a hub between the functional modules 10 and the measurement and control system cabinet 30. It centrally connects and transmits the measurement and control signals from multiple functional modules 10 to the measurement and control system cabinet 30. The system signal integration box 20 features a standardized box design, enabling secure transfer of measurement and control signals and ensuring reliable communication between at least one functional module 10 on-site and the measurement and control system cabinet 30. The system signal integration box 20 supports the connection of multiple functional modules 10 and accommodates future expansion needs by reserving spare terminals.

[0028] The measurement and control system cabinet 30 is connected to the system signal integration box 20. The measurement and control system cabinet 30 is the terminal of the measurement and control system 1000, and is used to complete the centralized monitoring and management of at least one functional module 10 on site. The measurement and control system cabinet 30 can be a PLC cabinet, a DCS cabinet, or an intelligent control cabinet.

[0029] Functional module 10 is equipped with a modular signal integration box 101, which can be a box-shaped design. This box can be pre-designed and assembled, and the wiring design within it can be determined based on the types of measurement and control signals that the measurement and control components 102 of the corresponding functional module 10 may generate, as well as the number of signal transmission lines 50 required for each measurement and control signal. Once the wiring design is complete, the wiring work within the box 101 is moved to a factory environment, and then assembled with the functional module 10 at the construction site, reducing the amount of wiring required on-site.

[0030] The modular signal integration box 101 may be provided with a first terminal block for aggregating and connecting the signal transmission lines 50 of the measurement and control components 102. The first terminal block can be arranged by measurement and control signal type (e.g., analog input AI, analog output AO, digital DI / DO, etc.) of the functional modules 10 and connected to the measurement and control components 102 via signal transmission lines 50 at the construction site.

[0031] Similar to the modular signal integration box 101, the system signal integration box 20 can also be pre-designed and assembled. The wiring design required for the system signal integration box 20 can comprehensively refer to the wiring design of each modular signal integration box 101. The wiring work inside the system signal integration box 20 is also moved forward to the factory environment for completion, and then the wiring assembly is completed with the modular signal integration box 10 and the measurement and control system cabinet 30 at the construction site, reducing the amount of wiring at the construction site.

[0032] At least one second terminal block is provided in the box body of the system signal integration box 20, and each second terminal block is used to correspond to a functional module 10, that is, the second terminal block can be connected to the functional module 10, or multiple second terminal blocks can be reserved vacant to facilitate the later expansion of the functional module 10, thereby ensuring the scalability of the measurement and control system 1000.

[0033] Each functional module 10 can be connected to its corresponding second terminal block, physically isolating the wiring of different functional modules 10 and avoiding signal crosstalk and incorrect parallel connections, common in related wiring techniques. Furthermore, when the measurement and control system 1000 issues an alarm, the faulty functional module 10 can be directly identified by the number on the second terminal block, narrowing the scope of troubleshooting from the entire measurement and control system 1000 to a single functional module 10 and shortening the diagnostic process.

[0034] One end of the first terminal block is integrated with a first quick-connector 103, which is mounted on the housing of the modular signal integration box 101 and is visible from the outside. The first quick-connector 103 serves as the signal output interface for the functional module 10. One end of the second terminal block is integrated with a second quick-connector 201, which serves as the signal input interface for the system signal integration box 20. The first quick-connector 103 and the second quick-connector 201 are connected via a quick-connect cable 40, thereby connecting at least one functional module 10 to the system signal integration box 20. The quick-connect cable 40 has plugs at each end corresponding to the first quick-connector 103 and the second quick-connector 201.

[0035] The other end of the second terminal block is connected to the measurement and control terminal of the measurement and control system cabinet 30 , thereby completing the signal transmission between the functional module 10 , the system signal integration box 20 and the measurement and control system cabinet 30 .

[0036] It should be noted that each first terminal block may be configured with multiple first quick-connect connectors 103. The number of first quick-connect connectors 103 can be determined based on the type of measurement and control signals transmitted between the first terminal block and the measurement and control element 102, and the number of signal transmission lines 50 required for each measurement and control signal. Similarly, each second terminal block may be configured with multiple second quick-connect connectors 201.

[0037] The capacity of the quick-connect cable 40 may also be determined according to the type of measurement and control signal and the number of signal transmission lines 50 required for each measurement and control signal.

[0038] Different from the related art, when performing wiring operations during on-site construction, the operator needs to strip the signal transmission line 50, crimp the terminals, and tighten the screws to complete the wiring work between the functional module 10 and the system signal integration box 20. The measurement and control system 1000 of the embodiment of the present application moves most of the wiring work to a controlled factory environment by adopting a pre-assembled modular signal integration box 101 and a system signal integration box 20. At the construction site, it is only necessary to connect the first quick-plug connector 103 and the second quick-plug connector 201 through a quick-plug line 40 to achieve "plug and connect" between the modular signal integration box 101 and the system signal integration box 20. The operator only needs to complete the simple actions of alignment and insertion to quickly establish a reliable connection between the modular signal integration box 101 and the system signal integration box 20, shortening the wiring work of a single functional module 10 that originally took hours to complete to minutes.

[0039] For example, a measurement and control system 1000 for nuclear power plants includes 20 functional modules 10. Using related art construction methods, on-site wiring requires over 800 connection points. However, using the measurement and control system 1000 of the present embodiment reduces the number of on-site connection points to approximately 40, increasing construction efficiency by approximately 20 times. Furthermore, the factory-based pre-installation process ensures standardized and consistent wiring quality, reducing on-site wiring errors.

[0040] In this way, the measurement and control system 1000 provided in the embodiment of the present application can move most of the wiring work to the factory environment through the pre-assembled modular signal integration box 101 and the system signal integration box 20, greatly improving the on-site construction efficiency. At the same time, the quick-plug connection method between the modular signal integration box 101 and the system signal integration box 20 not only effectively reduces the probability of manual wiring errors at the construction site, but also significantly improves the assembly efficiency between the functional module 10 and the system signal integration box 20, thereby improving the on-site assembly efficiency of the measurement and control system 1000. In addition, when the functional module 10 needs to be repaired or replaced, physical isolation can be achieved by simply disconnecting the corresponding quick-plug connection, avoiding the tedious operation of removing a large number of wiring on the functional module 10 in the related art, and realizing the modular design of the measurement and control system 1000.

[0041] In some embodiments, the functional module 10 further includes a plurality of signal transmission lines 50. The plurality of signal transmission lines 50 are respectively connected to the plurality of measurement and control elements 102 and the first terminal block, and are used to transmit various types of measurement and control signals.

[0042] The plurality of signal transmission lines 50 are used to collect the measurement and control signals of the measurement and control element 102 to the first terminal block. Based on the plurality of signal transmission lines 50, different terminal areas can be arranged on the first terminal block to divide the plurality of signal transmission lines 50 into different areas for routing. Specifically, the signal transmission lines 50 can be conventional signal lines.

[0043] Multiple signal transmission lines 50 transmit various types of measurement and control signals, enabling dedicated lines for each type of measurement and control signal, avoiding crosstalk between different signals and ensuring transmission stability and accuracy. Furthermore, since each measurement and control signal is transmitted via a dedicated signal transmission line 50, when a measurement and control signal experiences an anomaly (such as a break, short circuit, or signal distortion), the corresponding faulty signal transmission line 50 and associated measurement and control element 102 can be quickly identified, preventing global signal interference. Furthermore, by monitoring the status (e.g., impedance and level) of each signal transmission line 50 and combining it with the centralized access points of the first terminal block, bad points can be quickly identified, reducing the time and cost of manual point-by-point testing, thereby improving the maintainability of the measurement and control system 1000.

[0044] In some embodiments, the plurality of signal transmission lines 50 include at least one of an AO signal transmission line, an AI signal transmission line, a DO signal transmission line, a DI signal transmission line, an RTD signal transmission line, and a TC signal transmission line.

[0045] By configuring different types of signal transmission lines 50, such as AO (analog output) signal transmission line, AI (analog input) signal transmission line 50, DO (digital output) signal transmission line, DI (digital input) signal transmission line, RTD (thermal resistor) signal transmission line and TC (thermocouple) signal transmission line, mutual interference between analog signals and digital signals is effectively avoided, ensuring high-precision transmission and transmission accuracy of measurement and control signals.

[0046] It's worth noting that the dedicated signal transmission line 50, in conjunction with the first and second terminal blocks, improves fault diagnosis efficiency. Specifically, when the measurement and control system 1000 triggers an alarm, the operator can quickly conduct a hierarchical troubleshooting process: first, based on the number of the second terminal block partitioned by functional module 10 in the system signal integration box 20, the operator can identify the faulty functional module 10. Then, within the modular signal integration box 101 of the faulty functional module 10, the operator can locate the faulty terminal area (such as the AI ​​analog signal transmission line access terminal area) by signal type. This further narrows the fault to a specific signal type. Finally, the operator can locate the faulty signal transmission line 50 and the corresponding measurement and control element 102 by following the pre-routed dedicated signal transmission line 50 (such as the AI ​​line labeled "PT-101 Pressure Transmitter 4-20mA Input"). This progressive diagnostic process simplifies the troubleshooting process, shortens diagnostic time, and further improves the maintainability and ease of operation of the measurement and control system 1000.

[0047] In some embodiments, each type of the measurement and control signal corresponds to at least one of the signal transmission lines 50 .

[0048] In some embodiments, the modular signal integration box 101 further includes a first integrated signal line 104. One end of the first integrated signal line 104 is a dispersed end connected to a plurality of terminal blocks of the first terminal block, and the other end of the first integrated signal line 104 is an integrated end connected to the first quick-connect connector 103.

[0049] The first integrated signal line 104 is a data line integrated at one end and dispersed at the other end. The dispersed end of the first integrated signal line 104 has multiple terminals for connecting to the first terminal block, and the integrated end of the first integrated signal line 104 is bundled to connect to the first quick-connect connector 103.

[0050] In this way, during the pre-assembly stage in the factory, the modular signal integration box 101 completes the standardized connection between the first terminal block and the first quick-plug connector 103 through the first integrated signal line 104, moving the manual wiring work in on-site construction to a controlled factory environment, thereby improving the wiring process quality and on-site construction efficiency.

[0051] At the same time, the first integrated signal line 104 is connected to the multiple connection terminals of the first terminal block via its distributed ends, enabling intensive transmission of multiple signals within the modular signal integration box 101. This maintains the independence of each signal channel (for example, the physical isolation of AI and DI signals) while also enabling the integrated connection of multiple signal transmission lines 50 through the integrated end of the first integrated signal line 104 connected to the first quick-connect connector 103. This is particularly suitable for industrial scenarios such as nuclear power plants, where reliability and maintainability are critical.

[0052] In addition, since the first integrated signal line 104 is located in the modular signal integration box 101 , the first integrated signal line 104 can be wired over a short distance, thereby reducing the impedance and capacitance in the signal transmission path.

[0053] In some embodiments, the system signal integration box 20 further includes a second integrated signal line 202. One end of the second integrated signal line 202 is a dispersed end connected to a plurality of terminal blocks of the second terminal block, and the other end of the second integrated signal line 202 is an integrated end connected to the second quick-connect connector 201.

[0054] The second integrated signal line 202 is a data line integrated at one end and dispersed at the other end. The dispersed end of the second integrated signal line 202 has multiple terminals for connecting to the second terminal block, and the integrated end of the second integrated signal line 202 is bundled to connect to the second quick-connect connector 201.

[0055] In this way, the system signal integration box 20 can also complete the standardized connection between the second terminal block and the second quick-plug connector 201 through the second integrated signal line 202 during the factory assembly stage, moving the manual wiring work in on-site construction to a controlled factory environment, thereby improving the wiring process quality and on-site construction efficiency.

[0056] At the same time, the second integrated signal line 202 is connected to the multi-connection terminals of the second terminal block via its distributed ends, enabling intensive transmission of multiple signals within the system signal integration box 20. This maintains the independence of each signal channel while also enabling the integrated connection of multiple signal transmission lines 50 through the integrated end of the second integrated signal line 202 connected to the second quick-connect connector 201. This is particularly suitable for industrial scenarios such as nuclear power plants, where reliability and maintainability are critical.

[0057] In addition, since the second integrated signal line 202 is located in the modular signal integration box 101 , the second integrated signal line 202 can be wired over a short distance, thereby further reducing the impedance and capacitance in the signal transmission path.

[0058] In some embodiments, the side of the second terminal block that is not connected to the second integrated signal line 202 is connected to multiple measurement and control terminals of the measurement and control system cabinet 30 through conventional signal lines.

[0059] Specifically, the wiring method between the second terminal block and the measurement and control system cabinet 30 can also be the same as that between the first terminal block and the functional module 10, that is, the second terminal block is also partitioned according to the type of measurement and control signal, and wired according to the type of measurement and control signal, thereby maintaining the consistency of measurement and control signal transmission.

[0060] In some embodiments, the plurality of measurement and control elements 102 output a plurality of types of measurement and control signals, the quick-connect cable 40 includes a plurality of connecting wires, and each type of the measurement and control signal corresponds to at least one connecting wire.

[0061] The quick-connect cable 40 is internally provided with multiple connecting wires, each connecting wire corresponding to a type of measurement and control signal (for example: AI / DO / RTD).

[0062] It should be noted that the quick-connect cable 40 needs to maintain a matching relationship with the first quick-connect connector 103 and the first terminal block, and the second quick-connect connector 201 and the second terminal block.

[0063] For example, the number of strands, wire sequence, and interface type of the connecting wires of the quick-connect cable 40 must be consistent with those of the first quick-connect connector 103 and the second quick-connect connector 201. The contact arrangement of the first quick-connect connector 103 corresponds to the order of the terminals of the first integrated signal line 104 on the first terminal block, thereby mapping the measurement and control signal type classification to the terminals of the first terminal block, then to the interface of the first quick-connect connector 103, and finally to the quick-connect cable 40.

[0064] In some embodiments, the modular signal integration box 101 is further provided with a first dust cover, and the first dust cover can be covered on the first quick-plug connector 103.

[0065] When first quick-connect connector 103 is disconnected, the first dust cap seals the connector, effectively preventing contaminants such as dust, oil, and moisture from entering the connector. Furthermore, in harsh industrial environments like nuclear power plants, the first dust cap prevents the deposition of radioactive dust, ensuring the long-term reliability of first quick-connect connector 103.

[0066] In some embodiments, the system signal integration box 20 is further provided with a second dust cover, and the second dust cover can be covered on the second quick-plug connector 201.

[0067] When the second quick-connect connector 201 is disconnected, the second dust cap seals the connector, effectively preventing contaminants such as dust, oil, and moisture from entering the connector. Furthermore, in harsh industrial environments such as nuclear power plants, the second dust cap prevents the deposition of radioactive dust, ensuring the long-term reliability of the second quick-connect connector 201.

[0068] like Figure 3 As shown, the embodiment of the second aspect of the present application further provides a wiring method of a measurement and control system 1000, which is used to integrate the measurement and control system 1000 provided by the embodiment of the first aspect of the present application. The wiring method includes: Step 10: Connect the first terminal block in the pre-integrated modular signal integration box to the multiple measurement and control components in the functional module.

[0069] Signal transmission cables are used to categorize and centrally connect the measurement and control signals (AO, AI, DO, DI, etc.) from the measurement and control components pre-assembled in the modular signal integration box to the first terminal block. Signal transmission cables can be grouped by type (e.g., analog and digital signals) and use shielded or twisted-pair cables to minimize interference between measurement and control signals.

[0070] The connection terminals of the first terminal block may be numbered and correspond one-to-one with the interfaces of the measurement and control element to ensure accurate transfer of the signals of the measurement and control element 102 .

[0071] Step 20: Connect the second terminal block in the system signal integration box to the multiple measurement and control terminals of the measurement and control system cabinet.

[0072] The second terminal block serves as a transfer interface between the system signal integration box and the functional modules. It can be connected to the corresponding measurement and control terminals of the measurement and control system cabinet via signal transmission lines. The interfaces of the second terminal block can be matched according to the signal definition of the measurement and control terminals of the measurement and control system cabinet (such as the I / O channels of the PLC), and secured with locking screws or spring terminals.

[0073] Step 30: Use a quick-connect wire to connect the first quick-connect connector of the first terminal row and the second quick-connect connector of the second terminal row.

[0074] Align the plugs on both ends of the quick-connect cable with the first quick-connect connector on the modular signal integration box and the second quick-connect connector on the system signal integration box, and lock them in place to prevent them from falling out. Quick-connect cables can integrate multiple connecting wires (such as multi-core shielded wire).

[0075] Thus, the quick-connect method provided by the embodiment of the present application pre-wires and configures the wiring in the modular signal integration box and the system signal integration box in the factory, thereby reducing the time required for on-site wiring. At the same time, this wiring method also realizes modular wiring of the measurement and control system. If a functional module needs to be upgraded or replaced, the quick-connect cable between the functional module and the system signal integration box can be quickly disconnected and replaced with a new functional module, ensuring production continuity without shutting down the entire measurement and control system.

[0076] After step 10, the wiring method of the measurement and control system 1000 may further include step 40: Step 40: Fix the modular signal integration box to the preset installation position of the functional module.

[0077] When the wiring work between the modular signal integration box and the functional module is completed, the modular signal integration box can be assembled on the preset installation position of the functional module by mechanical fixation, thereby ensuring the structural stability and wiring quality between the modular signal integration box and the functional module.

[0078] Before step 10, the wiring method of the measurement and control system may further include: pre-integrating the modular signal integration box in a factory environment, specifically including steps 01 and 02: Step 01, configure the layout of multiple terminal blocks of the first terminal block according to the measurement and control signal types of the multiple measurement and control elements in the functional module corresponding to the modular signal integration box, and the number of signal transmission lines required for each measurement and control signal.

[0079] Determine the number of terminals for each functional module based on the signal types (such as AI, DI, DO, etc.) of the functional module's measurement and control components and the number of signal transmission lines required for each signal. Arrange the multiple terminals of the first terminal block. For example, arrange AI signal transmission lines in one area (terminals numbered 1-8) and DI signal transmission lines in another area (terminals numbered 9-12).

[0080] Step 02: Connect the dispersed ends of the first integrated signal line to the multiple wiring terminals of the first terminal block, and connect the other end of the first integrated signal line to the first quick-connect connector.

[0081] Connect the core wires of the first integrated signal line to the corresponding terminals according to the layout of the multiple connection terminals of the first terminal block. For example, connect the core wires 1-8 of the dispersed section of the first integrated signal line to terminals 1-8, and connect the core wires 9-12 of the dispersed end of the first integrated signal line to terminals 9-12.

[0082] In this way, the wiring method provided in the embodiment of the present application divides the wiring into zones inside the modular signal integration box according to the type of measurement and control signal, effectively preventing signal mixing and improving the maintainability and scalability of the measurement and control system. The solution of using the first integrated signal line in conjunction with the first quick-connect connector not only ensures the accuracy of the wiring, but also greatly improves the wiring efficiency. At the same time, the wiring work inside the modular signal integration box is completed in a factory environment, reducing the wiring workload at the construction site and improving on-site construction efficiency.
