Performance Monitoring System For Precision Planter Based On Msp430-Ct171

Based on full consideration of the working conditions in the filed, a monitoring system for precision planter was designed using the technology of sensor, single-chip Microcomputer and wireless transmission. In this system, photoelectric sensor and MSP430 were used to detect the performance of the seeder-metering device and process the data respectively. It mainly detected the miss index, multiple index, seeding amount, seeding rate, the plant spacing and other performance parameters. In the sound-light alarm system, a indicator light was used to show the fault type and location, then the detected data and fault can be displayed on the LED. In order to acquire and analyze the data at real-time, a wireless transmission system based on Bluetooth was designed. FS-BT485Abluetooth module was used to communicate with the host computer. To ensure the uniformity of drilling and sowing, a stepping motor was used to control the seeding rate in the laboratory. The results showed that reliability of the sound-light alarm system was 100% and the photoelectric sensor could detect more than 95% seeds passed it.
