Description

Circuit on-off inspection device of master-slave structure

Technical Field

The invention belongs to the technical field of electricians, and particularly relates to a circuit on-off inspection device with a master-slave structure.

Background

In all areas of electrical technology, such as IT, power transmission and distribution, and industrial automation, the first step in system integration is to install electrical parts and wiring connections according to design. After the wiring work is completed and before the system is powered on and debugged, it is necessary to detect the quality of the wiring for the safety of electrical equipment and human beings. The current detection method comprises the following steps: the quality inspector uses a multimeter to detect whether the terminals which are to be communicated are actually communicated according to a circuit diagram or a wiring meter, and then records and reports the inspection result manually. The quality inspector needs to check and record the check result while looking at the circuit diagram or the wiring table, which is inefficient. Moreover, each result depends on the working attitude of a quality inspector, the conditions of omission and false detection are inevitable, and the reliability and the credibility of the detection result are not high.

The inspection devices convert a circuit diagram or a wiring table into a strip of inspection instructions by depending on the powerful computing power and the multimedia input and output capability of a computer, and transmit the inspection instructions to a quality inspector in a multimedia mode, thereby greatly reducing the requirements on the image recognition and other working capabilities of the quality inspector, and improving the working efficiency and the reliability of working results of the quality inspector. However, the computer is limited by the field when in use because of large volume and weight, and has certain difficulty in practical operation particularly for long-distance line detection.

There is a need to develop a circuit on-off inspection device that is more convenient to carry and use.
