Embodiment
[0018] Such as figure 1 As shown, the greenhouse temperature automatic control system based on temperature alarm of the present invention is mainly composed of microcontroller, electric heater, refrigerator, display, signal conversion circuit, storage, temperature alarm circuit and temperature sensor group 8 parts.
[0019] Wherein, microcontroller is the control center of the present invention, and its preferred MCS-51 single-chip microcomputer realizes. The temperature sensor group includes a plurality of temperature sensors, and each temperature sensor is evenly distributed in the greenhouse, so that the temperature in the greenhouse can be detected more accurately. The temperature sensor is preferably realized by the SMW temperature sensor produced by Shanghai Keqi Instrument Co., Ltd. The signal conversion circuit is used to convert the signal output by the temperature sensor into a digital signal, its input end is connected with the signal output end of the temperature s...

The invention discloses an automatic temperature control system for greenhouses based on temperature alarms, which is characterized in that it mainly consists of a micro-controller, an electric heater, a refrigerator, a display, a signal conversion circuit, and a storage device respectively connected to the micro-controller. , a temperature alarm circuit, and a temperature sensor group connected to the signal conversion circuit. The present invention can collect the temperature in the greenhouse in real time, and can automatically start the refrigerator or electric heater when the temperature in the greenhouse is too high or too low, so that the temperature can be adjusted timely and accurately, and the intelligence of temperature collection and temperature control can be realized. The invention provides good conditions for the growth of crops; meanwhile, the invention has a high degree of automation and can save labor. The temperature alarm circuit of the present invention can send out an alarm sound when the temperature of the greenhouse is too high or too low. If the alarm sound is issued for a long time, it means that the cooling or heating effect in the greenhouse is not good, and the planters need to check the control system in time.
Description
technical field [0001] The invention relates to the field of automatic control, in particular to an automatic temperature control system for greenhouses based on temperature alarms. Background technique [0002] The growth of crops is closely related to temperature. At present, many vegetables are grown in greenhouses. For greenhouses, the most important management factor is temperature control. If the temperature is too low, the vegetables will freeze to death or stop growing. It is not conducive to the growth of vegetables, so in the process of vegetable cultivation, the temperature of the greenhouse must always be controlled within the range suitable for vegetable growth. However, at present, the temperature control of the greenhouse mainly relies on manual control, which not only consumes a lot of manpower, but also is prone to errors. Contents of the invention [0003] The purpose of the present invention is to overcome the defects that the traditional greenhouse tem...
