Low power consumption wireless sensor network node

Abstract

The invention provides a low power consumption wireless sensor network node. Amount of nodes is substantially reduced. The node is suitable for realization of signal monitoring in an area in a special environment. According to a wireless sensor network, branch node positioning can be solved, time synchronization technology is realized, and a user application interface is realized. The wireless sensor network node comprises a sensing detection unit, a processing control unit, a radio communication unit and a power supply unit. C language programming is employed by wireless sensor network node software, effective data is packaged in design, and formats are a lead code, an address, an effective data load and a check code. To an nRF403 chip, using 0x55FF as the lead code in a UART mode is supported. The address is identifiers of different response points. The effective data load comprises a data packet satisfying an upper level design protocol format. The check code is added at an end of the data packet, and validity of the data can be verified. Data packaging and processing are all realized by the processing control unit.

Description

Technical field: [0001] A wireless sensor network node designed with MSP430F149 processor and wireless transceiver module. Background technique: [0002] Wireless sensor network is a multi-hop self-organizing network formed by a large number of cheap micro sensor nodes deployed in the monitoring area and formed by wireless communication. An important feature of the wireless sensor network is that it gets rid of the connection restrictions of the traditional sensor network, solves the cost problem, and has been widely used, but has not formed a unified standard. Although the current Zigbee-based wireless sensor network technology realizes the collection, transmission and comprehensive processing of large-scale distributed data information, its further application and development are limited due to the high power consumption of sensor nodes and the high cost of base station construction. develop. Wireless sensor nodes are disposable and require low power consumption of the n...
