Remote wireless real-time greenhouse environment monitoring system

Abstract

The invention discloses a remote wireless real-time greenhouse environment monitoring system and a remote wireless real-time greenhouse environment monitoring method and belongs to the field of remote real-time carbon dioxide monitoring. The monitoring system comprises a monitoring server, a plurality of remote data repeaters which are respectively connected with the monitoring server through a general packet radio service (GPRS) wireless communication network, and a plurality of greenhouse environment monitoring instruments which are wirelessly interconnected in a star-shaped local area network structure by taking each remote data repeater as the center, wherein each remote data repeater comprises a power module, a microcontroller, as well as a short-range wireless receiving module, a SD storage module, a liquid crystal display (LCD) module and a GPRS wireless transmission module which are respectively connected with the microcontroller; and each greenhouse environment monitoring instrument comprises a power module, a microcontroller, as well as a greenhouse environment sensor group, a global position system (GPS) positioning module and a short-range wireless transmitting module which are respectively connected with the microcontroller. The monitoring requirements of wide-range discretization and narrow-range dense distribution in the greenhouse environment are considered, and the monitoring system is simple in structure, flexible in point distribution, remote, real-time, wireless in transmission, real-time in display, low in cost and low in power consumption.

Description

technical field [0001] The invention relates to a carbon dioxide remote wireless real-time monitoring system, in particular to a greenhouse environment remote wireless real-time monitoring system and method. Background technique [0002] At present, there are four main ways to monitor the greenhouse environment: (1) On-site monitoring: monitoring personnel carry thermometers, hygrometers, carbon dioxide concentration meters and other instruments with them to conduct passive on-site monitoring and recording of the greenhouse environment, and the labor cost is huge; (2) Automatic monitoring Monitoring: Integrate temperature, humidity, light, carbon dioxide and other sensors into the same monitoring equipment, and place them in the greenhouse environment for automatic collection. Operators regularly copy the monitoring data in the data storage card, which is difficult to achieve remote data collection and poor real-time performance; (3) Remote monitoring: connect the greenhouse...

Problems solved by technology

[0008] The above methods either use SMS Modem as the transceiver device, or do not integrate multiple sensor nodes, or use ZigBee technology to build a wireless sensor network, or use GSM short messages for abnormal alarms, but ignore the fact that the greenhouse environment often has large-scale discrete and small-scale Due to the dense distribution characteristics, if short-distance radio frequency transmission methods such as ZigBee are used purely, it is difficult to meet the monitoring needs of large-scale discrete distribution. high
