Embodiment Construction

[0040] FIG. 1 is a functional block diagram of an Ethernet multi-channel communication server in a preferred embodiment of the present invention. It includes CPU1, Ethernet interface module 2, program memory 3 composed of large-capacity FLASH modules, important data memory 4 also composed of large-capacity FLASH modules, photoelectric isolation module 5, RS-485 interface module 6, power supply module 7, And common data memory 8. The hardware watchdog 9 is also used to ensure that the server can run safely and reliably for a long time.

[0041] Among them, except the RS-485 interface module 6 and the power supply module 7, other modules are directly controlled by the CPU. The CPU is connected with the RS-485 interface module through the photoelectric isolation module, so as to realize the communication with the external 485 equipment, including the transmission of control commands and data, and realize the intelligent management of the 485 equipment. During specific implement...

Abstract

The Ethernet multipath communication server thereof comprises an Ethernet interface module and a RS-485 interface module; it also comprise a CPU, a photoelectric isolation module and a memory; said Ethernet interface module is connected to said CPU; said photoelectric isolation module is connected between the RS-485 interface module and CPU in order to make the Ethernet interface module communicate with the RS-485 interface module via said CPU and photoelectric isolation module.

Description

technical field [0001] The present invention relates to an Ethernet multi-channel communication server, more specifically, relates to an Ethernet multi-channel communication server capable of connecting multiple RS-485 interface module devices to Ethernet and controlling and managing them and its control method . Background technique [0002] Two ways of serial communication and parallel communication can be used for data transmission between computers or between computers and terminals. In terms of serial communication, RS-232 interface (also known as EIA RS-232) is a commonly used serial communication interface. Due to some technical deficiencies in RS-232, such as high signal level of the interface, low transmission rate, weak anti-noise interference, limited transmission distance, etc., some new interface standards have emerged continuously, RS-232 485 is one of them. [0003] The signal level of the RS-485 interface module is lower than that of RS-232, and it is not ...
