Handheld tractor remote-communication instrument

A handheld tractor remote-communication instrument comprises a microprocessor module, a power management module, a GPS module, a GPRS module and a CAN bus communication module, wherein the microprocessor module is connected with the GPS module, the CAN bus communication module is connected with the microprocessor module, the GPRS module is respectively connected with a monitoring center and the microprocessor module, and the power management module is connected with the microprocessor module. Information interaction between the handheld tractor remote-communication instrument and the monitoring center is realized via a GPRS network so that remote monitoring on the running state of a tractor and parameter calibration are realized. The handheld tractor remote-communication instrument has good stability and reliability and strong universality and can be used for upgrading software and hardware conveniently.
