Multi-interface coordinator of wireless sensor network

Abstract

The invention relates to a multi-interface coordinator of a wireless sensor network, comprising a core board, an expansion board, a wireless communication module and a power supply module. The core board further comprises a microcontroller module and a memory module, wherein the microcontroller module comprises a plurality of peripheral interfaces; and the expansion board is connected with the core board by the peripheral interfaces provided by the microcontroller module. The invention has the advantages of selectively using the microcontroller comprising a plurality of peripheral interfaces to satisfy the access needs of a plurality of control buses and network sorts so as to shorten the design period and decrease the production cost; and the microcontroller module further comprises an Ethernet controller and a data-processing unit which are integrated in the same chip.

Description

【Technical Field】 [0001] The invention relates to the field of communication technology and industrial control, in particular to a wireless sensor network multi-interface coordinator suitable for industrial control. 【Background technique】 [0002] In the industrial control system, a large number of control systems such as DCS, PLC, fieldbus and industrial Ethernet are used. Various sensors, transmitters and actuators installed in the industrial field are connected to the control system through various cables. Perform detection and control of related parameters. However, these methods have some inherent shortcomings: for certain mobile devices, such as rotating equipment and frequently moving monitoring objects, fixed cables cannot be connected; cables are expensive, and the connection between the control room and the field is sometimes When reaching thousands of meters, the connection cables of many nodes are very expensive; the numerous nodes make the connection extremely compl...

Problems solved by technology

However, these methods have some inherent deficiencies: for some specific mobile equipment, such as rotating equipment and frequently moving monitoring objects, fixed cables cannot be connected; the cost of cables is high, and the connection between the control room and the field is sometimes Up to thousands of meters, the connection cables of many nodes are costly; the many nodes make the connection extremely complicated, and the installation and maintenance are very difficult

However, they can only provide a single interface and protocol conversion, but there are dozens of types of control buses and networks in industrial control, and the hardware interfaces and network protocols are different from each other.

For different bus interfaces or network protocols, designers need to design a dedicated ZigBee coordinator separately, and the product design cycle and production cost are huge
