Abstract:

Aiming to achieve operation area and boundary recognition, and operation area real-time automatic measurement on rice transplanter, and then according to the GPS positioning information acquisition, operation area and boundary recognition algorithm and automatic calculation algorithm of operation area to research, an automatic measurement system of working area used in rice transplanter had been designed based on STC MCU and GPS module. At the same time, each hardware module structure was optimized and the corresponding driver was programmed with the C language. The system received GPS location information by GPS module, and calculated the operation area of farm machinery. The experiment results showed that the real-time measuring system could record information including operating time, workplace, operating area and cost. At the same time, the system had higher measurement accuracy for the irregular areas, and a large data sharing degree, low price, and the relative error can reach about 1.25%. It is very useful for other kinds of agricultural machinery completed measurement of the operation area, and to some extent it can provide the basis for the precision agriculture development. 
