Application background
With the advent of the network economy era, the application of IP networks based on the TCP/IP protocol has been widely popularized. The use of network resources can realize the network access of equipment, and equipment network monitoring has become the development trend of industrial automation.
Hengyi’s multi-serial protocol conversion solution can connect traditional serial devices in the industrial field to the IP network, and realize two-way data exchange between multiple serial devices of different protocols and Ethernet.
Success Stories of Hengyi
Remote distributed equipment control
Communication management of electric power, telecommunications, and automation equipment
Security, fire protection intelligent alarm system
system structure
With the application of Hengyi’s multi-serial communication protocol conversion solution, the conversion from RS232/485/422, CAN to TCP/IP communication protocol can be realized through simple design, and the remote monitoring and management of industrial field equipment can be realized. On the PC host side, you can access multiple serial devices on the serial server through a WEB browser. The system architecture is shown in the figure:
System hardware design
Hengyi multi-serial communication solution is an industrial communication protocol conversion solution for interconnection and communication of devices with different protocols. The solution uses AT91RM9200 as the main processor; the multi-serial port expansion is realized by the 16c554 chip, and a piece of cpld (altera’s epm7064) realizes efficient multi-serial interrupt source management, and the interrupt source is used to manage multiple extended serial ports; the data acquisition module is realized by ADS7842, And the DG506 chip realizes the selection of the data acquisition channel; the CAN communication module is realized by the CAN controller SJA1000. System block diagram:
System software design
1) Multiple protocol support: Interface devices with communication protocols such as RS232, RS485, RS422, CAN, etc. can be directly connected to serial protocol conversion devices.
2) Remote parameter setting
The system running on the multi-serial protocol conversion device realizes the function of the embedded WEB_Server, connects the network and the protocol conversion device, and logs in through the IE browser, and its working parameters can be set, as shown in the figure:
Solution advantage
The multi-serial communication scheme realizes the networking and centralized management of serial devices. The program converts the serial data of the existing RS232, RS485 and other equipment in the industrial field into TCP/IP data, and accesses and manages the data through the IP network. Adopting Hengyi’s multi-serial communication solution, without replacing the existing serial equipment, and without investing a lot of manpower and material resources, can realize real-time data collection, production monitoring, and network automation management in the industrial field.
