Abstract

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 multi-channel 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 process the signals. The test results show that the laser receive circuit can receive the laser signals efficiently, filter the natural light and meet the requirement of the laser location in the short distance.
