Embodiment Construction

[0050] The structure of the wireless monitoring system for grain storage capacity information of the present invention is as follows: figure 1 As shown, the system mainly includes: a CAN bus-based grain data acquisition subsystem in the warehouse, a Zigbee-based granary grain data transmission subsystem, a GPRS-based grain depot grain data transmission subsystem, and a central server subsystem. In the wireless monitoring system, there are a total of N granaries in a certain granary. Each granary is equipped with temperature, humidity, pressure and other sensors. Each sensor connects the signal to the CAN bus through the CAN data acquisition module. Each granary is equipped with a CAN bus. Each CAN bus is provided with a Zigbee node, which is provided with a conversion module for conversion between wired data acquisition and wireless data transmission, and a Zigbee master module and a GPRS module are installed in each grain depot to realize It communicates wirelessly with Zi...

Abstract

The invention relates to a grain cabin capacity information wireless monitoring system, monitoring method and networking method, belonging to the wireless communication and networking technical field. The grain tank capacity information wireless monitoring system of the invention comprises a cabin grain condition data acquisition subsystem based on CAN bus, a cabin grain condition data transmission subsystem based on Zigbee, a cabin grain condition data transmission subsystem based on GPRS and a center server subsystem; wherein the wire data acquisition network based on CAN bus is combined with the wireless data transmission network, thus not only playing the advantages of simple power supply and high reliable data transmission of the wired network, but also playing the advantages of no wiring, low cost and low power consumption of the wireless transmission network; and ZigBee short distance wireless communication is combined with GPRS long distance wireless communication, the advantages can be mutually compensated, and cabin grain condition monitoring in long-distance range is realized. The system can adapt to sensor output signal meeting industrial standard, is compatible with heterogeneous sensor and has strong generality.

Description

technical field [0001] The invention relates to a wireless monitoring system, a monitoring method and a networking method for realizing real-time, online and networked monitoring of storage capacity information and networking of storage capacity information by means of wireless communication, and belongs to the technical field of wireless communication and networking. Background technique [0002] As an important strategic resource in our country, food is the foundation of the national economy and a major event related to the national economy and people's livelihood. The quantity, quality and safety of food are directly related to the overall situation of national economic development and social stability. The food issue has always been a key issue that the Party Central Committee, the State Council and governments at all levels pay close attention to. For a long time, the country's grain reserves have not been significantly improved since the founding of the People's Repub...
