High-precision temperature and humidity adjustment system

Abstract

The invention provides a high-precision temperature and humidity adjustment system, which adjusts indoor temperature and humidity by using a central processing device, an air outlet, a casing, a display, a handle, an input device, a storage box, a memory, a humidity sensor, a signal processing circuit, a temperature sensor, a humidity regulator, and a temperature regulator. In the prior art, onlythe humidity sensor is used to test the environmental humidity, and the test precision is not high. On the basis of the poor test accuracy, the constant-temperature constant-humidity adjustment naturally has errors. Here, the signal processing circuit is used to process the signal collected by the humidity sensor. Further, the temperature sensor is greatly affected by the zero drift, and the temperature signal collected by the temperature sensor needs to be zero-drift corrected. The signal processing circuit provided by the invention can greatly improve the accuracy of temperature and humiditytesting, which makes the temperature and humidity adjustment more precise.

Problems solved by technology

[0005] Therefore, in order to overcome the above problems, the present invention provides a high-precision temperature and humidity adjustment system, which utilizes a central processing unit, an air outlet, a housing, a display, a handle, an input device, a storage box, a memory, a humidity sensor, a signal processing circuit, The temperature sensor, the humidity regulator and the temperature regulator adjust the indoor temperature and humidity, and the humidity sensor and the temperature sensor are arranged outside the constant temperature and humidity adjustment device to more accurately know the indoor temperature and humidity, because the prior art Both the humidity sensor and the temperature sensor are set in the constant temperature and humidity adjustment device. Since the humidity regulator and the temperature regulator of the constant temperature and humidity adjustment device are also set in the constant temperature and humidity adjustment device, if the humidity sensor and the temperature sensor are both set In the constant temperature and humidity adjustment device, it will cause inaccurate detection of the ambient temperature and humidity in the room that needs to be adjusted, and then make the constant temperature and humidity adjustment inaccurate. Moreover, in the prior art, only the humidity sensor is used to measure the ambient humidity. Test, the test accuracy is not high, on the basis of the test accuracy is not high, the constant temperature and humidity adjustment will naturally have errors, here, use the signal processing circuit to carry out signal processing on the signal collected by the humidity sensor, at the same time, the temperature sensor is affected by zero Drift has a great influence, and the temperature signal collected by the temperature sensor needs to be corrected for zero drift. The signal processing circuit provided by the present invention can greatly improve the accuracy of temperature and humidity testing, thereby making the adjustment of temperature and humidity more accurate.
