Description

Measurement equipment detection system

technical field

The invention relates to the field of automatic detection, in particular to a measurement equipment detection system.

Background technique

The quality inspection of smart energy meters and collection terminals includes full performance inspection before arrival, sampling inspection after arrival, and full inspection and acceptance inspection after arrival. The current automatic inspection line realizes the full inspection and acceptance inspection after the arrival of the goods. The test items only include a small number of performance test items such as function and insulation and withstand voltage. In the full performance test, more than 60 tests were carried out. Each test equipment is completely independent and distributed in different laboratories. After many tests are completed, they need to be sent to the functional test laboratory for error detection. table process. According to the current working method, the full-performance test of electric energy meters of Jibei Company generally selects 10 samples and divides them into three groups to carry out at the same time. It usually takes about 20 days for single-phase meters and about 25 days for three-phase meters. If the amount of bidding is relatively concentrated, it will take longer, which may delay the implementation of the full inspection and acceptance work. In addition, the current detection methods have high requirements for test personnel, especially for electromagnetic compatibility tests. There are few test personnel who can master and understand each standard proficiently, and the training period is long, especially when it involves personnel flow. The impact is very obvious.

The existing automated assembly lines are all used for the production or full inspection and acceptance of a single product, with fewer test items and no general test capabilities for different products. The research on the automatic detection method of electromagnetic compatibility test and the automatic detection pipeline of full performance test is still blank. At the same time, at present, energy meters and electricity information collection terminals use turnover boxes as transfer equipment in storage, transfer, and testing. Different types of energy meters and collection terminals use different turnover boxes, so the storage and transfer of different products are different. Processing, different types of electric energy meters and collection terminals cannot be transferred on one automatic meter detection line at the same time. There are two ways for the current automated testing system to transfer the tested samples, one is the assembly line method, and the other is the automatic AGV trolley method. The assembly line method is used to transfer the tested samples, which occupies a large area. It is not flexible to adjust the transportation position after installation, and the test sequence between various tests cannot be flexibly adjusted. It is suitable for test systems with fewer test points and fixed test items. The automatic AGV trolley method uses the automatic AGV trolley as the transfer tool for the test samples in the system. The automatic AGV trolley is small in size, flexible in operation, easy to change the trajectory, has low requirements on the site, and can flexibly adapt to different test procedures. It is suitable for many test items. An automated system with a lot of changes in the test process. At present, the automatic assembly line for full inspection and acceptance adopts both methods. There are many power companies that adopt the assembly line method.
