In order to realize the pinpoint of the work machinery in the paddy field, the receiver which can be used in the laser three-point location system has been designed. The laser receiver consists of MCU process circuit, photoelectric detection circuit, multi-channel gating circuit and differential-mode amplify circuit The photoelectric detection circuit is used to receive the laser signal, the multichannel gating circuit is controlled by MCU to select the channel, the differential-mode amplify circuit is used to eliminate the influence from natural light and the MCU process circuit is used to pr...
