Embodiment
[0017] like figure 1 As shown, the present invention is mainly composed of a microcontroller, a display, a heater control electromagnetic switch, a fan control electromagnetic switch, a heater, a fan, a signal processing unit, an analog-to-digital conversion module and a temperature sensor.
[0018] The temperature sensor is set in the farm to collect the temperature in the farm and output the corresponding analog signal to the analog-to-digital conversion module. It is realized by the FST600-101 temperature sensor produced by Hunan First Sensor Co., Ltd. The analog-to-digital conversion module is used to convert the analog signal output by the temperature sensor into a digital signal and output it to the signal processing unit. The analog-to-digital conversion module is implemented by using the AD7810 analog-to-digital conversion chip. The -pin is connected to the signal output interface of the temperature sensor, and its DOUT pin is connected to the signal input terminal of ...

The invention discloses an integral-circuit-based temperature automatic control system used for a farm. The temperature automatic control system is characterized by mainly comprising a microcontroller, a display, a heater control electromagnetic switch, a draught fan control electromagnetic switch, a signal processing unit, a heater, a draught fan, an analog-to-digital conversion module and a temperature sensor, wherein the display, the heater control electromagnetic switch, the draught fan control electromagnetic switch and the signal processing unit are connected with the microcontroller; the heater is connected with the heater control electromagnetic switch; the draught fan is connected with the draught fan control electromagnetic switch; the analog-to-digital conversion module is connected with the signal processing unit; and the temperature sensor is connected with the analog-to-digital conversion module. According to the temperature automatic control system, a detection signal is more stable after being processed by the signal processing unit, thus the microcontroller can perform identification and comparison on the detection signal more precisely, and the control precision of the temperature inside the farm is improved.
Description
technical field [0001] The invention relates to the field of poultry breeding, in particular to an automatic temperature control system for farms based on an integral circuit. Background technique [0002] During the growth process, pigs are connected and interacted with the environment in various ways. Among them, temperature has a very close relationship with the growth and health of pigs. At present, people usually use a temperature control system to monitor and adjust the temperature of the farm in the process of raising pigs, so as to create a suitable temperature environment for pigs to promote the growth of pigs. However, the currently used temperature control system has low temperature control accuracy and cannot meet the needs of pig raising. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the currently used temperature control system has low temperature control accuracy, and provide an automatic temperature ...
