Abstract

An embedded mother board compatible with Zigbee protocol for industrial control computers is provided, which comprises a CPU module, a north bridge module and a south bridge module. The embedded mother board is characterized in that the mother board is provided thereon with a wireless access module compatible with the Zigbee protocol and connected with the south bridge module. The wireless gateway module based on the Zigbee protocol is integrated into the mother board of the industrial control computer, so as to avoid the damage due to the repeated access to the external wireless gateway and the inconvenience for carrying the computer, improve the reliability and stability in controlling the computer system, and meet the requirement for on-site supervision outdoors under bad conditions of strong vibration and strong acid / base.

Description

technical field [0001] The invention relates to an embedded industrial control computer motherboard, in particular to the design and development of an embedded industrial control single-board computer motherboard compatible with the Zigbee wireless protocol standard. Background technique [0002] Zigbee wireless protocol is a communication protocol standard based on IEEE 802.15.4, including two specifications for the physical layer and media access control layer for low-speed wireless personal area networks, and the working frequency bands include 2.4G, 868M / 915M and 433M Hz, etc. kind. At present, the 2.4G frequency band is mostly used, and its channel data transmission rate can reach 250Kbits / s. It supports single-hop star and multi-hop peer-to-peer topology networking. It consumes the least power among various communication protocols at present, and is mainly used for low-speed short-range wireless. Personal area networks, wireless sensor networks, wireless industrial mo...
