Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

Shown in (Fig. 1), gather conversion equipment (1) and mainly form by temperature sensor (4), humidity sensor (8), CO2 concentration collector (5), potential of hydrogen collector (6), intensity of illumination collector (7) and modulate circuit (9).At the required controlling factor of planting greenhouse, as: temperature, humidity, potential of hydrogen, illuminance, CO ₂Concentration adopts different sensors and collector image data.The signal of gathering is transferred to modulate circuit (9) with electric signal, input signal is carried out the filter amplifying processing first time, then signal is imported high-speed a/d conversion chip (10), to obtain stable signal by modulate circuit (9).

Analyze with treating apparatus (2) and comprise singlechip controller (11), clock supervision circuit (12), reset circuit (14) and system power supply (13).Singlechip controller (11) mainly is the voltage signal that collection conversion equipment (1) is sent into to be converted into digital analogue signal according to the single-chip microcomputer good processing requirements of making and settlement (seeing program flow diagram for details) in advance send into data output and dispensing device.In the processing signals process,, abnormal conditions are done reset processing, recover initial state by reset circuit (14) processing single chip work operation exception state.By clock supervision circuit (12) the processing single chip work period.System power supply (13) is used for obtaining high performance working power, to guarantee monolithic function steady operation.

Data output and dispensing device are made up of liquid crystal display circuit (16) and short message sending module (17) and USB transmission circuit (15).The digital analogue signal of single-chip microcomputer output sends the staff in three kinds of modes, and first kind is signal to be sent into liquid crystal display circuit show in the mode that digital lcd shows, is used for monitoring constantly; Second kind is that signal is sent into short message system, sends on staff's the mobile phone with the short message form by each base station of GSM network; The third is to be transported to Surveillance center by USB interface, and Surveillance center can pass through MICROCOMPUTER PROCESSING analytic record data, takes the respective handling measure.
