The present invention provides a line diagnostic instrument, which is used for line diagnosis of construction machinery. The line diagnostic instrument includes: a storage unit, used to store at least one line layout information of construction machinery; a reading unit, according to the operator's input Instructing to read the line layout information corresponding to the current construction machine to be detected from the storage unit, and to select the information of the current wiring harness to be detected from the line layout information of the current construction machine to be detected according to the input instruction of the operator; the detection unit , detecting the current wire harness to be detected according to the information of the current wire harness to be detected and obtaining a detection result; a display unit configured to analyze the detection result to generate a diagnosis result, and display the diagnosis result. Through the present invention, it is possible to realize rapid and efficient diagnosis of engineering machinery wire harness faults at the construction site. The invention also provides a line diagnosis method.
Description
technical field [0001] The invention relates to the technical field of line diagnosis, in particular to a line diagnosis instrument and a line diagnosis method. Background technique [0002] For construction machinery, the electrical components of the electrical system are arranged all over the vehicle. These components are connected to the central control components through the wiring harness to form a complete electrical system. The wiring harness is huge and complex. However, the working environment of construction machinery may be quite harsh, resulting in frequent failures of various wiring harnesses, which greatly reduces construction efficiency. Most of the existing line fault diagnosis is judged by the experience of operators. The diagnosis speed is slow and the accuracy is low, which cannot meet the requirements of efficient construction of construction machinery. Especially in concrete pump trucks, this problem is more prominent. [0003] Therefore, how to quickl...
