Abstract
The invention relates to a greenhouse humiture monitoring alarm device based on a single-chip microcomputer. The device comprises a humiture sensor monitoring system and an alarm system and is characterized in that the humiture sensor monitoring system comprises a temperature sensor, a humidity sensor, an AT89C51 single-chip microcomputer, a data acquisition circuit, an LED display, an A/D convertor, an analog input channel and an alarm circuit. The device is advantaged in that with characteristics of small-scale farmer planting, in combination with the GSM wireless communication technology, the single-chip microcomputer is taken as a processor, the high-precision digital humiture sensor is taken as measurement equipment, problems of low manual monitoring efficiency and unmanned humiture early warning limit value alarm are solved, labor cost is reduced, and demands of storage and analysis of the historical humiture data of the agricultural facility environment can be further satisfied.
Description
Technical field
The present invention relates to agriculture field, particularly to SCM Based green house temperature-humidity monitoring alarm.
Background technology
China is industrialized agriculture big country in the world, according to statistics, China's heliogreenhouse and plastic greenhouse cultivation area respectively reach 330,000 hectares and 670,000 hectares at present, but the Modernization of China's industrialized agriculture is but the most slowly, according to Yangling Area, some areas, Shaanxi Province investigational data, New-type green house humiture observation system because with high costs, difficult in maintenance, cost performance is low etc., and reason uses less, a lot of middle-size and small-size peasant households or enterprise still use and manually check epidemic disaster meter and send staff on duty to carry out guiding agricultural production, its efficiency is low, and cost of labor is high.
Summary of the invention
For existing technical deficiency, the present invention provides SCM Based green house temperature-humidity monitoring alarm.
To achieve these goals, the technical solution used in the present invention is: SCM Based green house temperature-humidity monitoring alarm, it is made up of Temperature Humidity Sensor monitoring system and warning system, it is characterized in that, described Temperature Humidity Sensor monitoring system includes temperature sensor, humidity sensor, AT89C51 single-chip microcomputer, data acquisition circuit, light-emitting diode display, A/D conversion, analog input channel and alarm circuit.
Described Temperature and Humidity alarm device operation principle is: the indoor temperature and humidity that described Temperature Humidity Sensor will be measured, send in AT89C51 single-chip microcomputer after amplification, A/D are converted to digital quantity, temperature and humidity measurement value is demonstrated again by LED, if reaching the humiture reference value being pre-designed in single-chip microcomputer, then can be reported to the police by warning circuit prompting.
Beneficial effects of the present invention: for the feature of small-sized Cotton Varieties by Small Farming Households, in conjunction with gsm wireless communication technology, and using single-chip microcomputer as processor, using high-precision digital temperature-humidity sensor as the equipment of measurement, the present invention devises a kind of system based on single-chip microcomputer temperature-humidity monitoring GSM mobile handset SMS alarm function, solve that personal monitoring's efficiency is low and the warning problem of humiture early warning limit value during unmanned, reduce labour cost, storage, the demand of analysis to humiture historical data in industrialized agriculture environment can also be met simultaneously.
Accompanying drawing explanation
Fig. 1 is the circuit theory schematic diagram of the present invention.
Detailed description of the invention
As shown in the figure, SCM Based green house temperature-humidity monitoring alarm, it is made up of Temperature Humidity Sensor monitoring system and warning system, it is characterized in that, described Temperature Humidity Sensor monitoring system includes temperature sensor, humidity sensor, AT89C51 single-chip microcomputer, data acquisition circuit, light-emitting diode display, A/D conversion, analog input channel and alarm circuit.
Described Temperature and Humidity alarm device operation principle is: the indoor temperature and humidity that described Temperature Humidity Sensor will be measured, send in AT89C51 single-chip microcomputer after amplification, A/D are converted to digital quantity, temperature and humidity measurement value is demonstrated again by LED, if reaching the humiture reference value being pre-designed in single-chip microcomputer, then can be reported to the police by warning circuit prompting.
