| According to the current rice seedlings tent monitoring of the present situation of the shortage, we designed a set of
universal solar power supply type cold rice seedlings tent sending mining. The system can realize the process of cold rice seedlings seedlings relative environmental parameters of the automatic detection, display, storage, and according to the collection of data, different stage of seedlings seedlings physiological needed to be automatic ventilation and irrigation, sending by hardware with low power consumption device structure, reducing the power consumption equipment operation, solar standby power supply mode also guaranteed the power quality and power supply reliability. The safe and stable operation of equipment were 4~20 mA, 0 ~2 v, digital signal and general sensor interface, strengthen the equipment in general. The system can effectively guarantee period of cold rice seedlings in different production requirements, to cultivate strong seedling, improve the yield of rice and the quality has the important meaning. The mining control appliance has small volume, operation speed, high precision, large storage capacity, reliable operation, precise control, low temperature resistant high humidity etc. |
