Development of an Impact-Based Yield Monitor with CAN-Bus
It is necessary to develop grain yield monitor system in precision agriculture. In order to obtain correct grain yield information, a dual-plate differential impact-based yield sensor with CAN-bus was developed. The hardware system included six sensors, a DGPS signal module, CAN-bus com-munication modules, a conditioning circuit, a microcontroller and a screen. Meanwhile, in order to make the system work together, a software system was developed. It consisted of five main func-tions, periodically acquiring signals on CAN-bus and DGPS, receiving operators command, showing real-time yield, processing data, and storing them. The yield sensor could effectively reduce the noise caused by the vibrations of combine harvester and other reasons, and obviously improve the signalto-noise ratio. The CAN-bus communication modules could greatly reduce the complexity of connections, and improve system reliability. Laboratory and field tests showed that the whole system reduced the noise effectively, and worked steadily.
