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

Abstract

The invention discloses a low-power wireless sensor network device for status monitoring of logistics vehicles. The device is installed at different locations of the logistics vehicle to form a wireless network, and includes a sensor interface circuit, a Zigbee RF module, a communication interface circuit, and is used to control Zigbee RF. Key circuit for module start and end configuration, indicator light circuit for indicating the start and end of configuration of the Zigbee RF module, power module, and switch control circuit for controlling the power supply of the power module. This invention is based on the Zigbee wireless sensor network and designs a universal sensor interface, which is suitable for most logistics vehicle monitoring sensors. It realizes low power consumption of the product by designing switch circuits and software, and configures the device wirelessly or wiredly through the host computer software. After completing the monitoring task, the product functions can be flexibly reconstructed to adapt to logistics vehicles in different situations, making operation more convenient and maintenance costs 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...
