Multi-channel anti-interference transmitter

Abstract

The present invention discloses a multi-channel anti-interference transmitter which comprises a sensor sensitivity consistency adjustment module, a signal filtering module, a sensor signal amplification and zero point adjustment module, a same-phase amplification module, an opposite-phase amplification module, a voltage conversion module, a current conversion module, a polarity inverting module, a power supply secondary and third voltage stabilization module, a variable power supply input module, and a power module. The input end of the sensor sensitivity consistency adjustment module is electrically connected to 8 paths of sensors, and the sensor sensitivity consistency adjustment module is used for adjusting the sensitivity of the sensors. The output end of the sensor sensitivity consistency adjustment module is electrically connected to the input end of the signal filtering module. The signal filtering module is used for filtering the impurities in the signals emitted by the sensors. According to the multi-channel anti-interference transmitter, the sensor signals can be amplified for many times and can be adapted to the interference of the signals by a complex and harsh environment, and the synchronized output of the current signal and the voltage signal can be realized.

Description

Technical field [0001] The invention relates to the technical field of signal output equipment, in particular to a multi-channel anti-interference transmitter. Background technique [0002] The transmitter is a converter that converts the output signal of the sensor into a signal that can be recognized by the controller. The sensor and the transmitter together constitute a monitoring signal source for automatic control. [0003] Traditional transmitters can only output a single voltage or current signal under fixed conditions. When encountering complex and harsh environments, ordinary amplifiers often fail to collect the correct signal due to high-frequency interference, power supply and other factors. Signals and industrial environments require simultaneous output of voltage and current. The existing transmitters on the market cannot meet the ever-changing needs of the market. Summary of the invention [0004] The purpose of the present invention is to solve the shortcomings in th...
