Remote temperature monitoring system based on amplitude stabilizing circuit

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.
