Embodiment

[0019] Such as figure 1 As shown, the present invention is mainly composed of a microcontroller, a signal transmission processing module, an analog-to-digital conversion module, an amplitude stabilization circuit, a temperature sensor, a GPRS wireless transmission module and a mobile terminal.

[0020] The temperature sensor is set at the detection site, used to collect the temperature in the detection site and output the corresponding analog signal to the amplitude stabilization circuit, which is realized by the FST600-101 temperature sensor produced by Hunan First Sensor Co., Ltd. After the amplitude stabilization circuit processes the signal, it transmits the signal to the analog-to-digital conversion module. The analog-to-digital conversion module is used to convert the analog signal output by the amplitude stabilization circuit into a digital signal and output it to the signal transmission processing module. The analog-to-digital conversion module adopts The AD7810 analog...

Abstract

The invention discloses a remote temperature monitoring system based on an amplitude stabilizing circuit. The remote temperature monitoring system based on the amplitude stabilizing circuit is characterized by mainly comprising a micro-controller, a GPRS wireless transmission module, a signal transmission processing module, an analog-to-digital conversion module, an amplitude stabilizing circuit,a temperature sensor and a mobile terminal; the GPRS wireless transmission module and the signal transmission processing module are separately connected with the micro-controller; the analog-to-digital conversion module is connected with the signal transmission processing module; the amplitude stabilizing circuit is connected with the analog-to-digital conversion module; the temperature sensor isconnected with the amplitude stabilizing circuit; and the mobile terminal is connected with the GPRS wireless transmission module through a wireless network. The signal transmission processing modulecan filter low-frequency interference signals and high-frequency interference signals in detection signals; influence of the interference signals is eliminated; therefore, the detection signals transmitted to the mobile terminal through the wireless network are relatively accurate; furthermore, the detection signals are amplified; the strength of the detection signals is improved; therefore, weakening of the detection signals due to long-distance transmission is made up; and thus, the temperature monitoring precision is increased.

Description

technical field [0001] The invention relates to the field of temperature monitoring, in particular to a wireless temperature monitoring system. Background technique [0002] Driven by high technology, society is entering the era of real digitization, intelligence and networking, and temperature, as an important physical quantity, is one of the most common and important process parameters in the industrial production process. With the continuous development of industry, the requirements for temperature measurement are getting higher and higher, and the measurement range is getting wider and wider, and the requirements for temperature detection technology are getting higher and higher. However, the traditional temperature monitoring system does not have high precision in temperature monitoring and cannot meet people's needs. Contents of the invention [0003] The purpose of the present invention is to overcome the defect of low temperature monitoring accuracy of the traditi...
