Hydraulic excavator engine and variable pump composite control online monitoring system

Abstract

The invention discloses a hydraulic excavator engine and variable pump composite control online monitoring system. The hydraulic excavator engine and variable pump composite control online monitoringsystem comprises a master controller, an engine control unit, a variable pump control unit, a GPRS / GSM wireless transmission module and a monitoring center. The engine control unit comprises an enginecontroller, a rotation speed sensor and a position information sensor. The variable pump control unit comprises a pump controller, a proportional pressure reduction valve and a hydraulic system sensor. According to the provided hydraulic excavator engine and variable pump composite control online monitoring system, on the basis of the GPRS / GSM mobile internet and the CAN distributed bus technology, an engine and a variable pump are independently or compositely controlled, data are collected and stored online, whether the work mode of the engine and the variable pump meets the actual work condition or not can be remotely monitored, and timely diagnosis, correction and debugging are convenient; and it is guaranteed that the engine is in the best state, correlation between the internet and heavy industry equipment is achieved, and enterprises are more in datamation, informatization and intelligence in industry management.
