A low-power wireless sensor network device for logistics vehicle status monitoring

Abstract

The present invention discloses a low power consumption wireless sensing network apparatus for logistic vehicle condition monitoring, wherein the apparatus is arranged on different positions of the logistic vehicle so as to form the wireless network, and comprises a sensor interface circuit, a ZigbeeRF module, a communication interface circuit, a keying circuit for controlling the starting and ending configurations of the ZigbeeRF module, an indicator light circuit for indicating the starting and ending configurations of the ZigbeeRF module, a power supply module, and a switch circuit for controlling power supply of the power supply module. According to the present invention, based on the Zigbee wireless sensing network, the versatile sensor interface is designed and is suitable for the most logistic vehicle monitoring sensors, the low power consumption of the product is achieved through design of the switch circuit and the software, and the product function can be flexibly reconfigured in the case of completion of the monitoring task by adopting the host computer software to configure the apparatus in a wireless or wired manner so as to be suitable for the logistic vehicles in different occasions, such that the operation becomes convenient, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of vehicle state monitoring, and more particularly, to a low-power wireless sensor network device for logistics vehicle state monitoring. Background technique [0002] With the continuous and rapid development of my country's national economy, the safety of logistics vehicles in transit has always been a major issue that plagues the industry and the government. Once a safety accident occurs during the transportation of logistics vehicles, it will cause great harm to the lives and property safety of the public. If the transport is hazardous chemicals, it will also cause serious pollution and damage to the ecological environment. In recent years, there have been many major safety accidents of logistics vehicles in our country. If we can realize the comprehensive monitoring, tracking and early warning and alarm of the safety of logistics vehicles in transit, we can greatly reduce and avoid accidents, control the developm...

Problems solved by technology

For various signals, if a single signal acquisition module is used, the cost is high, the versatility is not strong, and it is not easy to maintain

[0004] In addition, signal acquisition sensors generally need to be installed at various acquisition points on the vehicle. Power supply and wiring are difficult problems. Traditional wired data acquisition and transmission systems have disadvantages such as high cost, difficult wiring, and high maintenance costs. General wireless data acquisition and transmission system, there are also problems such as high energy consumption, unstable data transmission, serious interference or inability to form a network
