Description

Technical Field

[0001] This utility model relates to the field of protocol conversion and transmission technology, specifically to an intelligent control multi-path expansion module that supports multiple protocols. Background Technology

[0002] With the development of modern industry, more and more equipment is being put into use, and communication between equipment is becoming increasingly frequent and important. However, the existing data acquisition communication lines mainly connect various power supply equipment and acquisition equipment through actual lines. In industrial sites, there are often multiple generations of equipment coexisting. These devices cannot communicate due to protocol differences. For these different types and protocols of equipment, separate wiring must be run to connect them, which increases the complexity of the lines and the difficulty of wiring implementation. For new equipment using traditional point-to-point wiring methods, the lines need to be reconfigured, which is time-consuming and has high maintenance costs. Summary of the Invention

[0003] To address the aforementioned technical problems, the purpose of this utility model is to propose an intelligent control multi-channel expansion module that supports multiple protocols.

[0004] The objective of this utility model is achieved through the following technical solution. The intelligent control multi-channel expansion module supporting multiple protocols proposed in this utility model includes a circuit board mounted inside a computer. The circuit board integrates a protocol conversion module, a main control unit, a local control unit connected to the main control unit, an expansion management unit, a security protection unit, a status monitoring unit, and a power module unit. The protocol conversion module communicates with peripheral wireless communication modules and wired communication devices to achieve protocol conversion between different communication channels. The local control unit is connected to a local I / O interface via a point-to-point connection. The expansion management unit is connected to an expansion bus interface via a high-speed bus. The security protection unit is connected to peripheral alarm outputs via a point-to-point connection. The status monitoring unit is connected to an indicator light module via a point-to-point connection.

[0005] Furthermore, the wireless communication module includes WiFi, Bluetooth 5.0, and ZigBee 3.0 protocols and communicates with wireless devices. The wired communication devices include Modbus, RS485 / 232, CAN, and Profinet protocols and communicate with industrial wired devices.

[0006] Furthermore, the main control unit adopts the STM32H743 with ARM chip as its core.

[0007] Based on the aforementioned technical solution, this utility model has the following beneficial effects: (1) In industrial scenarios, the protocol conversion module on this module can enable protocol interoperability and interactive communication between different types and different protocols of equipment deployed in industrial sites, avoiding the problem of separate wiring connections, increasing line complexity, and increasing the difficulty of wiring implementation. (2) This module can realize point-to-point connection of multiple new devices, and the expansion management unit can also connect multiple expansion sub-modules through the expansion bus interface. There is no need to reconfigure the line, saving time and making maintenance convenient. (3) After the module realizes information interaction between different channels through protocol conversion, the main control unit and the peripheral local I / O interface, expansion bus interface, alarm output, indicator light module jointly realize the functions of equipment communication, control, safety protection and status monitoring in industrial scenarios.

[0008] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0010] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings: Please see Figure 1This utility model discloses a multi-protocol intelligent control multi-channel expansion module, comprising a circuit board integrating a protocol conversion module, a main control unit, a local control unit connected to the main control unit, an expansion management unit, a security protection unit, a status monitoring unit, and a power module unit. This circuit board is mounted inside a computer. The protocol conversion module communicates with peripheral wireless communication modules and wired communication devices, and is used to realize protocol conversion between different communication channels. The wireless communication module communicates with peripheral wireless devices, including WiFi, Bluetooth 5.0, and ZigBee 3.0 protocols. The wired communication devices communicate with industrial peripheral wired devices, including Modbus, RS485 / 232, CAN, and Profinet protocols. Signal data from the wireless communication module and wired communication devices are transmitted to the protocol... The conversion module, after protocol conversion by the protocol conversion module, interacts with the main control unit. In this embodiment, the main control unit is an STM32H743 with an ARM chip as its core. The main control unit transmits signal data to the local control unit, expansion management unit, security protection unit, status monitoring unit, and power module unit for communication. The local control unit is connected to the peripheral local I / O interface through a point-to-point parallel connection. The DI interface of the local I / O interface can collect feedback status signals from peripheral devices, the DO interface can control the output signals of peripheral devices (e.g., relay output signals), the AI ​​interface can collect the analog status of peripheral devices, and the AO interface can control the analog output of peripheral devices. The expansion management unit and the peripheral expansion bus interface are connected via SPI and I²C. The system utilizes high-speed bus design and multiple expansion interfaces for connection. The safety protection unit and external alarm outputs are connected in parallel via point-to-point connections. In this embodiment, relay dry contact outputs are used to provide fault-free output, commonly used for fault protection. The status monitoring unit and indicator light module are directly connected via point-to-point cabling to monitor input and output signals. This allows for monitoring the indicator lights to confirm the normality of the input signal when there is status feedback input, and to confirm the normality of the output signal when control is performed. The power module unit provides stable 3.3V, 5V, and 12V power to different modules, ensuring stable module operation and reducing the impact of power fluctuations on the equipment.
