Abstract

The invention discloses a programmable analog voltage signal control device based on pulse width modulation. The device comprises a microprocessor, a USB communication module, a pulse width modulationsignal output unit, a high-speed opticalcoupler and a pulse width modulation chip, wherein the USB communication module and the pulse width modulation signal output unit are connected to the microprocessor, the input end of the high-speed optical coupler is connected with the pulse width modulation signal output unit, and the pulse width modulation chip is connected with the output end of the high-speed optical coupler. According to the invention, output is intelligently controlled, a pulse width modulation signal can be converted into a programmable analog voltage signal, and the problem ofsudden empty skipping is avoided.

Description

technical field [0001] The invention relates to the field of optical and electronic measurement control, in particular to a programmable analog voltage signal control device based on pulse width modulation. Background technique [0002] For the existing control systems on the market that convert pulse width modulation signals into voltage outputs, most of them are controlled by analog chips. When adjusting the resistance, there will be a fault of instantaneous gap, when the voltage appears to be 0. The programmable control voltage automatic output system on the market has problems such as high power consumption and serious heat generation. The price is very expensive, the volume is relatively large, and the installation is inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a programmable analog voltage signal control device based on pulse width modulation, which can convert the pulse width modulation...
