Excavator self-detection system and method

Abstract

The invention discloses an excavator self-detection system and method. The system comprises a controller, an oil inlet flowmeter, an oil outlet flowmeter and a performance self-detection controller, wherein the oil inlet flowmeter and the oil outlet flowmeter are respectively arranged at an oil inlet and an oil outlet of an engine and are respectively connected with the performance self-detectioncontroller, and the performance self-detection controller is connected with the controller and is used for respectively reading signal values of the oil inlet flowmeter and the oil outlet flowmeter, calculating oil consumption values, reading machine parameters of an excavator through the controller and judging performance of the excavator. The method comprises the steps of performance self-detection, oil consumption test and efficiency test. The measuring device can be designed voluntarily according to different machine models and different communication protocols and is high in portability,and personnel waste is effectively reduced; and by adopting a self-detection function, the measuring accuracy is improved.

Description

technical field [0001] The invention relates to a detection system and method, in particular to an excavator self-detection system and method. Background technique [0002] The judgment of the performance of excavators mainly depends on indicators such as fuel consumption, digging efficiency, and digging force. It is particularly important to test the fuel consumption efficiency of excavators when the machine is put on the market or in the process of subsequent product performance upgrades. In terms of fuel consumption test, at present, the traditional machine fuel consumption test generally requires the joint participation of machine operators, fuel filling personnel and on-site counting personnel. Finally, stop the machine, fill up the oil again, and calculate the fuel consumption data according to the compensated oil amount. This process requires a lot of human resources. In addition, due to the uncertainty of the machine parameters by the operator, the test may be carri...

In terms of fuel consumption test, at present, the traditional machine fuel consumption test generally requires the joint participation of machine operators, fuel filling personnel and on-site counting personnel. After that, stop the machine, fill up the oil again, and calculate the fuel consumption data according to the compensated oil amount. This process requires a lot of human resources

In addition, due to the uncertainty of the machine parameters by the operator, the test may be carried out when the machine performance is abnormal. Repeated turning and shaking operations, if the operation is not complete, may easily lead to inaccurate measurement data; in terms of excavation efficiency testing, traditional testing requires the cooperation of operators and counting personnel, and the horn is used as the signal to start the test. Conditions, and then the counting personnel will count and remind the operator of the end time. The process is more complicated, and at the same time, due to the negligence of the counting personnel, it is easy to cause inaccurate counting
