When each module is installed, outdoor-monitoring node installation, in field, is convenient to testing environment illumination intensity and temperature; Indoor monitoring node installation is after heliogreenhouse on wall, and temperature sensor is distributed in warmhouse booth, and gained temperature is all temperature sensor detected value averages; Easily to get rusty in outdoor the shortcoming damaged for solving travel switch, and infrared emission is affected by environment less, and native system selects the photoelectric beam detector of correlation distance 250m, the demand of existing booth length can be met, therefore shutter stop means can adopt photoelectric beam detector and travel switch mode used in combination, photoelectric beam detector is installed on day-light greenhouse top, and travel switch is installed at the bottom of canopy, each one of two, maintains easily and overhauls.
For illustrating light filling process of the present invention further, composition graphs 3 illustrates,
Step 10, system completes start and judges, if do not carry out system initialization, waits for and goes to step 30 after 5 seconds; If not yet complete threshold value arrange or remodify the system initialization contents such as amendment, go to step 20, system enters initialization interface, and user according to plant demand, seasonal climate situation set temperature threshold value and intensity of illumination threshold value, can go to step 30 after completing this series of activities again.
Step 30, after system completes Initialize installation, application optical sensor detects real time environment light intensity, real time temperature inside and outside indoor and outdoor temperature sensor sensing chamber, and detected value is stored temporarily, undertaken being forwarded to central control room PC by 485 buses and carry out storage display, and go to step 40.
Step 40, according to the real-time lighting intensity that intensity of illumination threshold value and the step 30 of initializing set collect, judges whether the real-time light intensity of environment reaches the range of light intensity of setting.If be greater than Intensity threshold, then go to step 100; Otherwise then go to step 50.
Step 50, according to the spacing module dissengaged positions of shutter, if infrared emission cuts off, travel switch is not cut off, be then determined as shutter and be positioned at ceiling, otherwise is then determined as at the bottom of canopy, goes to step 60 after having differentiated.
Step 60, differentiates whether shutter is positioned at ceiling, is positioned at ceiling and goes to step 70, otherwise go to step 90, keeps shutter standing state, i.e. closed condition.
Step 70, be positioned at ceiling if differentiate, the first CPU (central processing unit) analyzing and processing, sends control high level by the P0.5 of I/O mouth, the auxiliary reclay of control shutter is connected, opens shutter, and go to step 80.After definition exports high level, relay is connected, and opens shutter and reverses power supply, shutter is reversed and puts down booth cotton-wadded quilt or straw screen or mat; Output low level makes relay turn off, and instant rolling screen electromechanical source turns off, thus shutter is stopped operating.
Step 80, two position-limiting units are all in connection duty, detect shutter and whether arrive assigned address, this step is mainly used in shutter and closes, if travel switch is cut off, then disconnects shutter and controls power supply, close shutter, on the contrary duplicate detection, till travel switch is cut-off.
Step 100, when external environment illumination intensity satisfies condition, according to the indoor and outdoor temperature that set temperature threshold value, internal-external temperature difference scope and step 30 detect in real time, judge whether temperature reaches reasonable request, satisfied then go to step 110, on the contrary go to step 30 and again detect.
Step 110, meets step 100 established temperature, and after light temperature joint control logical algorithm, reading system current time value, greenhouse is opened and should be adapted with reasonable time on same day section, judges whether current time belongs in the reasonable time section of setting, go to step 120 if belong to, otherwise go to step 30.
Step 120, meet illumination, temperature, light temperature joint control logic and reasonable time section time, the first processing unit detects spacing module dissengaged positions, and if infrared emission be cut off; be judged as greenhouse roof, on the contrary travel switch cut off then be judged as at the bottom of canopy; If be judged as at the bottom of canopy, first CPU (central processing unit) sends steering order, make P0.4 export high level and connect auxiliary reclay, shutter is made to start to rotate forward, first CPU (central processing unit) starts to detect spacing module status simultaneously, if infrared emission is cut off, control P0.4 output low level, makes relay disconnect, thus shutter is stopped operating, shutter is opened to assigned address; If be judged as ceiling, then keep original state, do not carry out any operation.
