Method and device for determining transmitter parameters

Abstract

The invention provides a method for determining parameters of a transmitter, comprising: a controller receives a plurality of test data sent by a terminal device, and generates analysis data of each test data; a current generator converts each analysis data, and generates each The current signal corresponding to each analysis data; the transmitter converts multiple current signals separately to generate the voltage signal of each current signal; the monitoring feedback circuit receives the voltage signal of each current signal sent by the transmitter, and performs each voltage signal for each current signal. Each voltage signal is converted and processed to generate a digital voltage signal corresponding to each voltage signal; the controller receives the digital voltage signal sent by the monitoring feedback circuit, and sends the digital voltage signal to the terminal device; the terminal device receives the digital voltage signal sent by the controller. , and determine the first parameter and the second parameter according to the digital voltage signal and test data. Thus, the test error of the transmitter is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a method and device for determining parameters of a transmitter. Background technique [0002] With the development and progress of society, the problem of air quality has attracted more and more attention. Gas composition (SO 2 , CO, O 3 , NO 2 , TVOC) as a routine monitoring project of air pollutants, one of the main indicators reflecting air dust particle pollution has been paid more and more attention by relevant state departments. The demand for electrochemical sensors to monitor the content of these gases is increasing, and the accuracy of monitoring is getting higher and higher. This urgently requires high-efficiency and high-quality electrochemical sensors, which requires a series of parameter calibrations before official use of electrochemical sensors, etc. Work. [0003] After the chemical reaction (oxidation, reduction) between the electrochemical sens...

Problems solved by technology

[0004] Electrochemical sensors are greatly affected by the environment in actual use, and in the absence of external auxiliary equipment, it is difficult to control the concentration of the target gas to be measured

Therefore, when the electrochemical sensor transmission board is detected and calibrated by using the electrochemical sensor and the measured target gas, there are unstable factors, which may easily cause test errors
