With the advent of the era of network economy, the application of IP networks based on the TCP / IP protocol has been widely popularized. The use of network resources can achieve network access for devices. Device network monitoring has become a development trend in industrial automation.
Hengyi's multi-serial port protocol conversion solution can realize the connection of traditional serial devices on the industrial site to the IP network , and realize the bidirectional data exchange between multiple serial devices with different protocols and Ethernet.

system structure
With the application of Hengyi's multi-serial communication protocol conversion scheme, it is possible to realize the conversion from RS232 / 485/422, CAN to TCP / IP communication protocol through simple design, and realize remote monitoring and management of industrial field equipment. On the PC host, you can access multiple serial devices on the serial server through the 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 applied to the interconnection communication of different protocol devices. The program uses AT91RM9200 as the main processor; the multi-serial port expansion is implemented with a 16c554 chip, and a multi-serial port interrupt source management is realized by a piece of cpld (altera's epm7064), using the interrupt source to manage multiple extended serial ports; the data acquisition module is implemented with ADS7842, And the selection of data acquisition channel is realized by DG506 chip; CAN communication module is realized by CAN Controller SJA1000.

System software design
1) Multi-protocol support: You can directly connect interface devices with RS232, RS485, RS422, CAN and other communication protocols to serial protocol conversion devices.
2) Remote parameter setting
The system running on the multi-serial protocol conversion device realizes the function of embedded WEB_Server, connects the network and the protocol conversion device, logs in through the IE browser, and can set its working parameters, as shown in the figure:
Solution advantages
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 devices on the industrial site into TCP / IP data, and accesses and manages the data through the IP network. Using Hengyi's multi-serial communication scheme, real-time data collection, production monitoring, and network automation management on the industrial site can be achieved without replacing the existing serial device or investing a lot of manpower and material resources.
The COB light series is a main light that improves the brightness of the stage lighting. The COB light with the focus function can be switched between the function of concentrating bright light and emitting soft light in a large area, so that it can meet the requirements of different brightness and spotlight on the stage. need. The difference between COB and other series is that white light and warm white light are mainly used in color, which is the main source of light on the stage, stand an important position on stage.
