[0035] Figure 1 schematically illustrates the structure of a batching plant operation control system according to an embodiment of this application. As shown in Figure 1, this application embodiment provides a batching plant operation control system, including:

[0036] The control box 100 and the electrical control cabinet 200 are located inside the mixing plant. The control box 100 and the electrical control cabinet 200 are connected in communication.

[0037] The operation box 100 includes an integrated PCB (Printed Circuit Board) main board, which includes an embedded PLC (Programmable Logic Controller) module 110 and a first communication module 120. The embedded PLC module 110 is connected to the first communication module 120 through the onboard bus of the integrated PCB main board.

[0038] The electrical control cabinet 200 includes a back panel, a PLC device 210, and a network device 220. The PLC device 210 and the network device 220 are mounted on the back panel via guide rails. The PLC device 210 includes a second communication module 212 and a core processing module 211. The core processing module 211 is connected to the second communication module 212 via a back panel bus. The second communication module 212 is connected to the network device 220. The network device 220 is communicatively connected to the first communication module 120.

[0039] It should be noted that the traditional batching plant control box 100 adopts a sheet metal shell structure, and its internal architecture, which connects buttons, indicator lights, and actuators such as relays and contactors in the electrical control cabinet 200 via multi-core cables and terminal blocks, has many shortcomings. To improve the production efficiency and control accuracy of the batching plant, this embodiment proposes a batching plant operation control system. Through lightweight improvements and a dual-PLC architecture, the wiring workload is reduced, a real-time communication link between the two PLCs is established, command transmission latency is reduced, and system scalability is improved.

[0040] Specifically, the mixing plant operation control system includes an operation box 100 and an electrical control cabinet 200. The electrical control cabinet 200 is located within the mixing plant and serves as the local control room, while the operation box 100 is the remote control unit. The operation box 100 utilizes a high-density integrated PCB motherboard, replacing traditional discrete components with an integrated design of an embedded PLC module 110 and a first communication module 120. Discrete components include buttons, indicator lights, and terminal blocks. This reduces the number of internal cables, decreases the thickness, and reduces the overall size of the operation box 100. It should be noted that the first communication module 120 is the module within the operation box 100 used for communication with the electrical control cabinet 200. The PCB motherboard achieves high-speed data exchange between the PLC and the communication module via an onboard bus, eliminating the need for external wiring. The onboard bus can include SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit). In one embodiment, the outer shell of the operating box 100 can adopt a 3D printing + PVC (Polyvinyl Chloride) film composite structure. While maintaining the IP65 (Ingress Protection 65) protection level, it is lighter than the traditional sheet metal box. The bottom can be embedded with silicone damping pads, which can withstand 1.5G continuous vibration and are suitable for mobile scenarios such as vehicle-mounted mixing stations.

[0041] In this embodiment, the second communication module 212 is the communication module within the PLC device 210 of the electrical control cabinet 200. The electrical control cabinet 200 employs a standardized backplane mounting system; the PLC device 210 and network device 220 are fixed via guide rails, supporting hot-swappable replacement and reducing the time cost of single-module maintenance and replacement. The backplane bus of the core PLC device 210 can provide very low signal transmission delay, ensuring that the second communication module 212 can obtain processing results in real time. The network device 220 is connected to the first communication module 120, enabling rapid communication with the operation box 100. The backplane bus may include a PROFINET backplane bus or a PCIe (PCI Express) bus.

[0042] It should be noted that in this embodiment, a dual PLC collaborative communication mechanism is adopted. The embedded PLC module 110 in the operation box 100 undertakes the tasks of signal acquisition and edge computing. After receiving the preprocessed data from the embedded PLC module 110 in the control cabinet 200, the core processing module 211 in the control cabinet 200 executes motion control command issuance and multi-device collaborative control logic.

[0043] Understandably, in practical applications, parameter settings are performed on the embedded PLC module 110 in the operator box 100 and the PLC device 210 in the electrical control cabinet 200 to achieve effective communication between the operator box 100 and the electrical control cabinet 200. Specifically, after selecting the corresponding port, the baud rate, data bits, stop bits, parity method, address, etc., of the embedded PLC module 110 and the PLC device 210 are set accordingly. After the parameter settings are completed, debugging and running will be performed to ensure that the operator box 100 and the electrical control cabinet 200 can communicate effectively.

[0044] In this embodiment, a dual PLC real-time communication link is constructed through the above-mentioned mixing plant operation and control system to reduce command transmission delay and improve system scalability, thereby improving the production efficiency and control accuracy of the mixing plant.

[0045] In one embodiment, the first communication module 120 includes a wired communication interface and a wireless communication interface. The wired communication interface includes an RJ45 interface (Registered Jack 45), an M12-D encoding interface (M12 Connector-Digital Encoding), and an M12-FOC (M12 Fiber Optic Connector) fiber optic interface. The wireless communication interface includes a 5G interface and a Wi-Fi 6 interface.

[0046] In one embodiment, network device 220 includes at least one of electrical control cabinet 200, a switch, and an industrial router;

[0047] The 200 switch in the electrical control cabinet is connected to the RJ45 interface via a Cat5e network cable, or to the M12-D coded interface via an M12-D to RJ45 patch cord or an M12-D straight-through cable.

[0048] The 200 switch in the electrical control cabinet is connected to the M12-FOC fiber optic interface in sequence via an opto-optical converter and a multimode fiber optic cable.

[0049] Industrial routers connect to 5G interfaces via 5G wireless communication technology;

[0050] The industrial router connects to the Wi-Fi 6 interface via the Wi-Fi 6 protocol.

[0051] In this embodiment, it should be noted that the first communication module 120 of the operation box 100 includes a wired communication interface and a wireless communication interface. The wired communication interface enables redundant transmission and industrial-grade reliability. The wireless communication interface enables high-speed mobility and wide-area coverage.

[0052] Specifically, the wired communication interfaces include an RJ45 interface, an M12-D coded interface, and an M12-FOC fiber optic interface. The RJ45 interface uses an industrial-grade RJ45 socket, supports CAT6A shielded network cable, and has a built-in EMC ferrite core, enabling low-cost, low-electromagnetic-interference cabling. This RJ45 interface connects to the embedded PLC module 110 via the onboard PHY (Physical Layer) chip on the PCB and to the switch in the electrical control cabinet 200 via a Cat 5e network cable. The M12-D coded interface features a 4-core X-code and vibration-resistant design. The switch in the electrical control cabinet 200 connects to the M12-D coded interface of the first communication module 120 via an M12-D to RJ45 patch cord or an M12-D straight-through cable. The M12-D coded interface can withstand strong vibration / shock environments and meet the requirements of frequent plugging and unplugging. The M12-FOC fiber optic interface supports OM3 / OM4 multimode fiber (Optical Multi-mode 3 / 4) and features very low connector insertion loss. The 200 switch in the control cabinet connects sequentially to the M12-FOC fiber optic interface of the first communication module 120 via an optoelectronic converter and multimode fiber. The M12-FOC fiber optic interface is suitable for long-distance, high-electromagnetic-interference areas or sensitive scenarios requiring physical isolation.

[0053] Specifically, the wireless communication interfaces include a 5G interface and a Wi-Fi 6 interface. The 5G interface supports 5G NR (5G New Radio Standalone) independent networking with an uplink rate of ≥50Mbps, meeting the needs of high-definition video surveillance and remote PLC program updates. Signal penetration can be improved by integrating an industrial-grade 5G module and using MIMO (Multiple Input Multiple Output) antenna diversity technology. The 5G interface can be used for cross-factory remote control, facilitating mobile device access. The Wi-Fi 6 interface can also reduce terminal power consumption by enabling the TWT (Target Wakeup Time) mechanism and is suitable for battery-powered portable operating box 100. The Wi-Fi 6 interface can be used in scenarios requiring high-density device access and low-latency control. The industrial router in the electrical control cabinet 200 connects to the 5G interface of the first communication module 120 via 5G wireless communication technology; or connects to the Wi-Fi 6 interface of the first communication module 120 via the Wi-Fi 6 protocol.

[0054] In this embodiment, through the collaborative design of multi-mode communication interfaces, industrial-grade reliability is ensured while cabling is simplified. Furthermore, based on this interface design, wireless backup can be automatically activated in the event of a wired failure, achieving seamless switching. It also enables full-scenario coverage, meeting the mixed access requirements of fixed and mobile devices. This further enhances the system's reliability, scalability, and anti-interference capabilities, while further reducing operation and maintenance costs.

[0055] In one embodiment, the operation box 100 further includes a power module for supplying power to the embedded PLC module 110 and the first communication module 120.

[0056] In one embodiment, the power module includes a 24V DC industrial power supply and enhanced Power over Ethernet (PoE).

[0057] In this embodiment, it should be noted that the power supply module of the operation box 100 adopts a dual power supply architecture design of 24V DC industrial power supply and enhanced Power over Ethernet (PoE++). The output power of the 24V DC industrial power supply can meet the peak load of the embedded PLC module 110, the first communication module 120, and the cooling fan, and has overvoltage, overcurrent, short circuit, and reverse connection protection, with a response time of <10μs, conforming to IEC 61508 SIL 2 (International Electrotechnical Commission 61508 Safety Integrity Level 2). The enhanced Power over Ethernet supports 90W power output, providing dual backup power supply for the operation box 100, and can seamlessly switch in the event of a failure of the 24V DC industrial power supply. In one embodiment, it can also be designed to support LLDP-MED (Link Layer Discovery Protocol-Media Endpoint Discovery) protocol for dynamic negotiation of power supply priority, ensuring that the PLC module always receives priority power. Enhanced Power over Ethernet enables hot-swapping of power supplies, allowing for online power replacement without downtime.

[0058] Referring to FIG2, in one embodiment, network device 220 includes industrial power supply switch 221.

[0059] Referring to Figure 3, in one embodiment, the electrical control cabinet 200 further includes a power supply device 222, which is used to supply power to the PLC device 210 and the network device 220. The power supply device 222 is an industrial-grade switching power supply.

[0060] In this embodiment, it should be noted that the power supply device 222 of the electrical control cabinet 200 can be an industrial-grade switching power supply to power the PLC device 210 and the network device 220. The three-phase power supply is connected to the switching power supply through a circuit breaker. The negative terminal of the switching power supply is grounded, and the positive terminal copper busbar is connected to the power terminals of the PLC device 210 and the network device 220.

[0061] Referring to Figure 2, in one embodiment, the network device 220 of the electrical control cabinet 200 can be an industrial power supply switch 221, which integrates power supply to the operator box 100. The industrial power supply switch 221 is internally connected to a 24V switching power supply and supplies power to the operator box 100 via enhanced Ethernet. By adopting the industrial power supply switch 221 that supports enhanced Ethernet, the electrical control cabinet 200 can simultaneously undertake data exchange and power supply functions, realizing the integration of power supply and communication and reducing system failure points.

[0062] In one embodiment, the integrated PCB motherboard also includes an I / O interface area.

[0064] The physical button is connected to the onboard bus of the integrated PCB motherboard via a spring pin socket, so as to connect to the DI input (Digital Input) pin of the embedded PLC module 110 via the onboard bus.

[0065] The DO output (Digital Output) of the embedded PLC module 110 is connected to the indicator light via a drive circuit.

[0066] In this embodiment, it should be noted that inside the operation box 100, the physical buttons and indicator lights are directly soldered onto the PCB and connected to the I / O pins of the embedded PLC module 110 through metallized holes, eliminating the risk of poor contact associated with traditional terminal blocks. This design significantly reduces the number of cables inside the operation box 100, and the overall thickness can be controlled to within 50mm. In one embodiment, the architecture design of the IO interface area of ​​the PCB motherboard can adopt a 6-layer PCB stacked design. The top layer is the signal layer, the second layer is the ground plane, the third layer is the power layer, the fourth layer is the DI signal layer, the fifth layer is the DO drive layer, and the sixth layer is the protective layer. The PCB motherboard is divided into functional areas: a DI input area for acquiring physical button signals; a DO output area for driving indicator lights; a communication interface area for connecting the first communication module 120; a power management area for voltage conversion and filtering; and a spare expansion area. Specifically, the physical buttons are connected to the onboard bus of the integrated PCB motherboard through spring-loaded sockets to connect to the DI input pins of the embedded PLC module 110 through the onboard bus. The DO output of the embedded PLC module 110 is connected to the indicator lights through a drive circuit. This enables a highly integrated PCB layout.

[0067] In this embodiment, the IO interface area is designed with an architecture of spring pin socket + onboard bus + isolated drive circuit, which realizes a highly reliable connection between the mixing plant operation panel and the embedded PLC, while meeting the stringent requirements of anti-interference, wide temperature range and moisture resistance in industrial scenarios.
