Problems solved by technology

However, many types of sensors currently lack a unified sensor parameter acquisition device, which is not convenient for the unified management and control of the sensors on the equipment loaded with sensors; The signal is easily disturbed by noise. Therefore, when collecting the parameters of the sensor, how to amplify and condition the collected signal to ensure better noise resistance and easier packaging is a problem that needs to be solved.

Abstract

The invention provides sensor parameter acquisition equipment with a signal conditioning function, which comprises a main processor. The main processor comprises a PL end and a PS end, and the parameter acquisition equipment further comprises a signal conditioning module and an analog-to-digital converter; the PL end comprises an ADC data acquisition module, a data caching module and a bus processing module. According to the invention, centralized acquisition, protocol analysis and signal coding can be carried out on each parameter of various sensors, amplification and signal conditioning can be carried out on signals generated by acceleration and other special sensors before parameter acquisition, better noise immunity is ensured, and packaging is easier.

Description

technical field [0001] The invention relates to the technical field of sensor acquisition, in particular to a sensor parameter acquisition device with a signal conditioning function. Background technique [0002] As a detection device, a sensor can sense the measured information and transform the sensed information into electrical signals or other required forms of information output to meet the needs of information transmission, processing, storage, display, recording and Control and other requirements, which involve a wide range of fields. However, many types of sensors currently lack a unified sensor parameter acquisition device, which is not convenient for the unified management and control of the sensors on the equipment loaded with sensors; Signals are easily disturbed by noise. Therefore, when collecting parameters of sensors, how to amplify and condition the collected signals to ensure better noise resistance and easier packaging is a problem that needs to be solved...
