MEASUREMENT DATA PROCESSING METHOD IN EXCAVATOR

Japanese Patent JP2015014146

A

PROBLEM TO BE SOLVED: To provide a measurement data processing method in an excavator, in which signal receiving of measurement data by a first measurement sensor and measurement data by a second measurement sensor can be synchronized by a data processing device.SOLUTION: An excavator is equipped with radio transmission means 9 having a transmission part 91 provided in an excavation shaft 4 and a receiving part 92 provided in a driving device of the excavation shaft 4. The radio transmission means 9 transmits measurement data by a first measurement sensor 6 from the transmission part 91 to the receiving part 92 in a time-division manner with radio transmission interposed in the middle therebetween. In a measurement data processing method in the excavator, the measurement data by the first measurement sensor 6 is transmitted to a data processing device 8 via the radio transmission means 9, and measurement data by a second measurement sensor 7 is transmitted to the data processing device 8 by wired communication. A buffer for temporary storage of the measurement data by the second measurement sensor 7 is provided, and the measurement data by the first measurement sensor 6 and the measurement data by the second measurement sensor 7 are synchronized and made to be received by the data processing device 8.
