Abstract

The utility model relates to a building block heat preservation house control device comprising a temperature signal collecting circuit, a signal enlarging circuit, a trigger circuit, a single chip micro-computer control circuit and a heating machine drive circuit. Output signals of the temperature signal collecting circuit are transmitted to the trigger circuit through the signal enlarging circuit. The output signals of the trigger circuit are transmitted to the single chip micro-computer control circuit and the heating machine drive circuit. The output signals of the single chip micro-computer control circuit are controlled and sent to a voice alarming circuit and a radio sensing (RS) 485 communication interface circuit. The RS 485 communication interface circuit is in communication with the single chip micro-computer control circuit in a bi-directional data mode. As a thermistor is adopted to detect the temperature in a building block heat preservation house, and the trigger control circuit controls the interior of the building block heat preservation house, when the temperature in the building block heat preservation house rises, the thermistor outputs temperature detection signals, the single chip micro-computer machine sends the temperature detection signals to a micro-computer after judgment, and the micro-computer can also be used to send out and set value of the temperature in the building block heat preservation house to achieve remote monitoring and setting of the temperature.
