The invention relates to the communication technology field, and discloses a communication line self repairing system, a bus network and an engineering machine. The communication line self repairing system, the bus network and the engineering machine are characterized in that a first power supply end and a first detection end of a first controller are respectively connected with a normal connection end of a coil and a contactor switch of a first relay, a first selectable connection end and a second selectable connection end of the contactor switch of the first relay are respectively connected with a first end of a first communication line and a first end of a first spare line, a first power supply end and a first detection end of a second controller are respectively connected with a normal connection end of a coil and a contactor switch of a second relay, and a first selectable connection end and a second selectable connection end of the contactor switch of the second relay are respectively connected with a second end of the first communication line and a second end of the first spare line. The communication line self repairing system, the bus network and the engineering machine can achieve self repairing of the communication lines, improve reliability of the communication lines, and not only are simple in structure and low in cost, but also are convenient to maintain.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a communication line self-repair system, a communication line and engineering machinery. Background technique [0002] Communication networks such as bus networks are widely used in construction machinery to share and transmit system information, and are the information center of construction machinery control. In practical applications, the bus network system is distributed in various parts of the whole machine. Therefore, if a part of the bus fails, it often causes the entire bus network system to fail to work normally, resulting in abnormal operation of related controls. [0003] The inventor of the present application found in the process of realizing the present invention that: due to the relatively mature development of the related chips of the bus and relatively stable reliability, common bus failures are usually caused by the communication lines of the bus, especial...
