Problems solved by technology

1. The traditional method needs to insert an ammeter on the wire and other conductors to sample the current, which has considerable limitations.
2. The data obtained by sampling is often sent to the data processing center through the wired transmission system. Since the wired transmission system needs to implement a large amount of wiring, it brings a lot of inconvenience to the system integration

Abstract

The invention provides a current monitoring system and method based on a wireless sensor network. The system comprises a host computer, an RS232 communications link, a network aggregation node, a Zigbee communication link and sensor nodes, and is characterized in that the sensor nodes collect current information; the sensor nodes are centered on the aggregation node to form a star topology network; the sensor nodes and the aggregation node are in communication connection via a Zigbee wireless transmission module; and the aggregation node and the host computer are in communication connection via an RS232 interface. By use of the technical scheme in the invention, current signals can be easily and flexibly monitored, the heavy cable work is effectively avoided, cordless communication is achieved, the cost of and difficulty in system layout are reduced and the project cycle is sped up.

Description

technical field [0001] The invention relates to current monitoring technology, especially the current monitoring technology based on wireless sensor network. Background technique [0002] In industrial control, it is often necessary to monitor the current parameters in a certain path, and use this to form the basis for judging the fault. 1. The traditional method needs to insert an ammeter on the wire and other conductors to sample the current, which has considerable limitations. 2. The data obtained by sampling is often sent to the data processing center through the wired transmission system. Since the wired transmission system needs to implement a large amount of wiring, it brings a lot of inconvenience to the system integration. [0003] A wireless sensor network is a network composed of sensor nodes with wireless data transceiver devices. It can dynamically monitor, perceive, and collect various information of objects, process the information, and send it to the remote...
