Problems solved by technology
[0003] When calculating the wire number length of the wire harness wire, the traditional method is to use manual calculation, but when the wire harness length is long, there are many nodes and a lot of wire numbers, manual calculation requires a lot of manpower and is easy to make mistakes
At present, there are also some professional wire harness calculation software, but they have strict requirements on the format of wire harness drawings. It is necessary to convert ordinary drawings into special formats before they can be used. The conversion process takes a lot of time. At the same time, the drawings of each company are different, and the conversion is difficult.

Embodiment
[0078] Embodiment: As shown in the figure, Table 1 is a list of dimensions between nodes in the wiring harness drawing, and Table 2 is a list of starting and ending points of line numbers. When it is necessary to calculate the length of line number 1, first query it from Table 2. The starting point of line number 1 is B, and the end point is A. Use recursive query from point B in table 1 until point A is found. When point A is not found at the top of table 1, return to the bottom of table 1 and continue Recursive query until point A is found. Record the dimensions of each section from point B to point A and add up the dimensions to obtain the length of line number 1.

The invention discloses a wire harness wire length calculating method based on a table. Lengths between all nodes of a wire harness are input into a wire segment length table, a path is searched for from the starting point of wire numbers in a recursion mode according to the input wire numbers until the ending point of the wire numbers is found; when the ending point is not found when recursion reaches the top end of the table, the bottom end of the table is returned to continue to be searched for the ending point, the lengths of all segments in the recursion searching process are recorded and added, and thus the length of a wire with the needed wire number is obtained. The wire harness wire length calculating method based on the table is simple in operation, calculation can be automatically carried out as long as all node and length information of a drawing is simply input into the table, dependence on the drawing is not needed, the format of the drawing is not required, automatic calculation of a macro command of the table is used, calculation is convenient, and the calculation accuracy is high.
Description
technical field [0001] The invention relates to a method for calculating the length of wires, in particular to a method for calculating the length of wire harness wires based on tables. Background technique [0002] In modern cars, there are a lot of car wiring harnesses, and the electronic control system is closely related to the wiring harnesses. Someone once made an image metaphor: if the functions of microcomputer, sensor and actuator are compared with the human body, it can be said that the microcomputer is equivalent to the human brain, the sensor is equivalent to the sensory organ, and the actuator is equivalent to the motor organ, then the wiring harness is the nerve and the human body. blood vessels. The automobile wiring harness is the network main body of the automobile circuit, which connects the electrical and electronic components of the automobile and enables them to function. Without the wiring harness, there is no automobile circuit. At present, whether it...
