A Container Monitoring System Based on Hybrid Networking

Abstract

The invention discloses a container monitoring system based on hybrid networking, which includes a container monitoring terminal, a container door monitoring terminal and a converging terminal. The container monitoring terminal includes a first wireless communication module, a temperature and humidity sensor, a vibration sensor and a gas concentration sensor , the first wireless communication module collects state parameters of temperature, humidity, vibration, and gas concentration, and sends the state parameters to the second wireless communication module in the door monitoring terminal. The second wireless communication module on the door of each container communicates with the container The first wireless communication modules of each in-box monitoring terminal form a star network. The present invention reduces the node scale of the traditional ZigBee network and effectively improves the response time of the system through the mixed protocol and mixed frequency on the one hand; on the other hand, it reduces the channel preemption and interference problems between wireless communications, and improves the reliability of the communication.

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
