Of excavator working reliability have great influence to the working efficiency, can be in the process of excavator excavator work all working parameters are recorded with analog sensor, on the one hand to give the driver alarm, act as a reminder, the other side can give professional evaluation, also can trigger system itself maintenance operations.

In addition, the use of dot matrix LCD display, can also provide a lot of useful tips for the driver, display operating manuals, for example, to tip the driver automatically after work time shall complete the maintenance work, etc.

In the development process of excavator, sometimes an urgent need to understand a lot of excavator working parameters, need excavator electric system can support this functionality, at this time to complete, and the size of the engine load in the system, hydraulic system of detection and multi-way valve, hydraulic motor, hydraulic pump, hydraulic cylinder work parameters, such as records, as well as in long-term work condition change of these parameters is to design a complete assessment, such as maneuverability, economy, reliability, energy saving, etc. Excavator work is needed in the process of interaction between electric parts timely detection of excavator working performance is stable, ensure the excavator work smoothly.
