Container monitoring system based on hybrid networking

Abstract

The invention discloses a container monitoring system based on hybrid networking. The container monitoring system comprises inner-container monitoring terminals, container door monitoring terminals and a converging terminal, wherein the inner-container monitoring terminals comprise first wireless communication modules, temperature and humidity sensors, vibration sensors and gas concentration sensors; the first wireless communication modules are used for acquiring temperature, humidity, vibration and gas concentration state parameters, and transmitting the state parameters to second wireless communication modules in the container door monitoring terminals; and the second wireless communication modules on container doors of containers and the first wireless communication modules in the inner-container monitoring terminals construct a star network. Through a hybrid protocol and hybrid frequency, the node scale of a conventional ZigBee network is lowered; the response time of the system is shortened effectively; the problems of channel preemption and interference among wireless communications are solved; and the communication reliability is enhanced.

Description

technical field [0001] The invention relates to a container monitoring system based on hybrid networking, which is especially applied to the scene where containers are highly stacked during container yard and water container transportation, and can also be applied to occasions such as state monitoring of vehicle-mounted and airborne container transportation processes. Background technique [0002] my country is the country with the largest transportation volume of energy and chemical raw materials in the world. Among them, most dangerous goods involve transportation in different places. Long-distance and large-volume transportation are the common conditions of water transportation of dangerous goods in my country. Due to the complicated stowage of containers on ships and the special form of container packaging and transportation, shipping personnel cannot timely grasp the internal conditions of containers, resulting in serious losses. When transporting dangerous goods in con...

AI Technical Summary

Problems solved by technology

Due to the stacking of containers inside the cabin, wireless signals based on GPRS / GSM technology cannot be transmitted, and the product cannot be extended to shipping containers

[0008] The above-mentioned systems are all single-point monitoring systems, and the monitoring objects are not connected to each other. When containers are stacked at high density in shipping, container yards, etc., the data of the containers pressed at the bottom or in the middle cannot be transmitted, so that the full monitoring cannot be realized. process monitoring
