Problems solved by technology
When the equipment is installed and checked for wiring, technicians need to check whether the line connections are correct one by one by comparing the electrical schematic diagram and the number marks on the number tube. When the number of connecting wires reaches hundreds, this method is inefficient and error-prone, and The power switchgear usually controls strong electricity, and if it makes a mistake, it will bring heavy losses to the enterprise

Embodiment Construction
[0019] Such as figure 1 As shown, a wire wiring inspection method using a visually recognized barcode, the wire is affixed with a label wire identification 1, and the wire identification 1 includes: an identification label 11 and a digital label 12, and the digital label 12 is set on the identification label 11 side, the identification label 11 is used for machine identification, and the digital label 12 is used for the operator to check; the specific inspection method is as follows:
[0020] (1) Use a high-resolution camera to take pictures of the wires in the power cabinet to obtain clear pictures;
[0021] (2) Using visual recognition technology to segment the barcode area of each wire to obtain the identification label 11 of each wire;
[0022] (3) Perform binary processing on the identification label 11 of each wire, determine the start bit of the barcode and the reference width of the barcode according to the width of the first black barcode in the identification labe...

The invention relates to a wire connection inspection method adopting a visual identification bar code, a label wire identifier is pasted on a wire, the wire identifier comprises an identification label and a digital label, the digital label is arranged at one side of the identification label, the identification label is used for machine identification, and the digital label is used for being checked by an operator. The number of the cable can be managed in a unified mode through the wire identification, the number distribution of the cable is obtained through the visual technology by means of common equipment such as a camera and a computer, whether wire connection is correct or not can be judged according to a circuit schematic diagram, and if errors exist, alarm information is given.
Description
technical field [0001] The invention relates to a visual recognition inspection method, in particular to a wire connection inspection method using a visual recognition barcode. Background technique [0002] In most power equipment enterprises, many processes still adopt traditional manual methods. For example, there are often a large number of connecting wires in switch cabinets and PLC control cabinets. In order to ensure correct wiring, number tubes are usually put on the wire insulation layer. There are number marks printed on the top, some use letters, some use numbers, or a combination of the two. The operator compares the circuit schematic diagram and connects one by one according to the wire number. When the equipment is installed and checked for wiring, technicians need to check whether the line connections are correct one by one by comparing the electrical schematic diagram and the number marks on the number tube. When the number of connecting wires reaches hundreds...
