Problems solved by technology

In the existing technology, it is usually necessary to manually test the circuit board with a large number of debugging equipment, such as manual dialing, manual remote control, and checking the corresponding test indicator light and display to judge whether the circuit board is qualified, which has high labor costs and high detection efficiency. Low-level problems, especially in large-scale testing, there are still problems of missed detection and false detection, which may cause unqualified instrument products to flow into the market. In addition, manual detection will inevitably touch the circuit board, and it is easy to insert and unplug the circuit board manually. Causes artificial damage to the circuit board, and even leads to the direct scrapping of the circuit board, which increases the inspection cost

How to improve the current low-efficiency manual testing methods and realize automatic, efficient and accurate detection of smart gas meter circuit boards has become an urgent technical problem in the industry
