The invention provides a warehouse temperature and humidity control system based on a single-chip microcomputer. The system comprises a controller module, a relay module, a sensor module, a power supply module, an alarm module, a communication module and a touch screen input module. The controller module is connected to the sensor module, the touch screen input module, the alarm module, the power supply module and the relay module. The controller module is also connected to the communication module. The relay module is formed by four relay circuits and is connected to a heating apparatus, a cooling apparatus, a humidification apparatus and a dehumidification apparatus. The control system is connected to mobile equipment, a network server and a computer through the communication module. The system has advantages that an indoor temperature and humidity can be effectively controlled so that the indoor temperature and humidity maintains to be an adaptive degree; a user can control the system remotely through a mobile phone or a computer application program; and the system uploads concrete data during operation to a network server and stores the data for query.
Description
technical field [0001] The invention relates to the technical field of temperature and humidity control systems, in particular to a single-chip microcomputer-based warehouse temperature and humidity control system. Background technique [0002] The temperature and humidity in the air are important factors affecting the storage of food, medicine and other items. If the humidity is too high, it will easily damage the equipment; if the humidity is too low, there will be too much dust in the factory building, which will affect the normal operation of the equipment; if the temperature is too high, some food and medicine will easily deteriorate; It is difficult for the operator to work normally. [0003] In the prior art, there are corresponding temperature and humidity control systems, which can control the indoor temperature and humidity to a certain extent, so that the indoor temperature and humidity can be maintained at an appropriate level, but these systems cannot realize r...
