Multi-serial communication protocol conversion scheme 
Application Background With the arrival of the era of network economy, the application of IP networks based on the TCP/IP protocol has been widely used. With the use of network resources, network access of devices can be achieved. Monitoring of device networking has become the trend of industrial automation.
Hengyin's multi-serial protocol conversion scheme can realize the access of the traditional serial devices on the industrial site to the IP network, and realize the two-way data exchange between multiple serial ports and Ethernet devices with different protocols. Hengsheng Success Story 
Remote Distributed Device Control Electricity, telecommunications, automation equipment communication management Security and fire intelligent alarm system The system architecture uses Hengyi's multi-serial communication protocol conversion scheme. It can realize the transition from RS232/485/422, CAN to TCP/IP communication protocol through simple design, and realize remote monitoring and management of industrial field devices. On the host side of the PC, multiple serial devices on the serial server can be accessed through a web browser. The system architecture is as follows: 
System Hardware Design Hengtong multi-serial communication solution is a protocol for industrial communication protocol conversion applied to the interconnection of different protocol devices. The program uses AT91RM9200 as the main processor; multi-serial expansion is implemented with 16c554 chip, and a high-efficient multi-serial interrupt source management is implemented by a cpld (alterma's epm7064), and multiple serial ports are managed by the interrupt source; the data acquisition module is implemented by ADS7842, And by the DG506 chip to achieve the data acquisition channel selection; CAN communication module by the CAN controller SJA1000. System block diagram: 
System software design 1) Multiple protocol support: Interface devices with RS232, RS485, RS422, CAN and other communication protocols can be directly connected to the serial port protocol conversion device.
2) Remote parameter setting The system running on the multi-serial protocol conversion device implements the function of the embedded WEB_Server, connects the network and the protocol conversion device, and logs in through the IE browser, and can set its working parameters as shown in the figure:
Advantages of the solution Multi-serial communication solutions realize the networking and centralized management of serial devices. The program converts the serial data of existing RS232, RS485 and other devices on the industrial site into TCP/IP data, and accesses and manages the data through the IP network. The use of constant serial multiple serial communication solutions, without replacing the existing serial devices, and without investing a lot of manpower and material resources, can achieve real-time data collection, production monitoring, network automation management on the industrial scene.
