Problems solved by technology

Due to the use of dedicated line communication, the wiring is complicated and the cost is increased. If the timing time is not corrected through the line communication, due to the traditional timing error, after several hours of operation, the accumulated timing error will make the system control action inconsistent, which may cause the system to collapse. In some occasions where the design is changed frequently and the amount of wiring engineering is large, the product application is limited

Abstract

The invention relates to a crop greenhouse climate control system, comprising a plurality of data acquisition devices, a plurality of electrical appliance controllers and a main controller, wherein the main controller contacts an owner via a GSM (Global System for Mobile Communications) network. The outputs of the electrical appliance controllers are serially connected to a power supply of furnace or pump electrical appliance equipment under the control of a photoelectric isolator, a two-way controlled silicon controller or a relay contact circuit, and the power-on power and time of loads of the electrical appliance controllers are thus controlled.

Description

(1) Technical field: [0001] The invention relates to a climate control system for a greenhouse of crops, which comprises a plurality of data collectors, a plurality of electrical controllers and a main controller, and the main controller communicates with the owner through the GSM network. The output of the electrical appliance controller is controlled by photoelectric isolation, bidirectional thyristor control or relay contact circuit, and connected in series to the power supply of furnace and pump electrical equipment to control its load power and time. (two) background technology: [0002] In the control system that is powered by the power grid, each electronic device or module communicates through a dedicated line to correct the timing time of each electronic device or electronic module to achieve the purpose of synchronous operation. Due to the use of dedicated line communication, the wiring is complicated and the cost is increased. If the timing time is not corrected t...
