A controller automatic detection method

Abstract

The invention discloses an automatic detection system for a controller, which includes a tested piece, and also includes a software firmware server, a testing machine, a support frame, and a testing control box; the software firmware server and the testing machine are interconnected; the testing machine is connected to the tested piece; The test piece is installed on the support frame, which is equipped with contacts, and the support frame is electrically connected to the detection control box; the external terminal of the test piece communicates with the detection control box through contacts; the software firmware server is equipped with a detection control box. Server software; the detection machine is equipped with a product detection software platform; the communication between the detection server software and the product detection software platform; the unloading part is configured in the tested part, and the detection control box uses the input channel of the unloading part to establish with the tested part communication. The invention adopts an automatic detection means to improve the detection efficiency and the accuracy of the detection results, and the detection results are archived to the software firmware server, which facilitates product tracking and maintenance and reduces production costs.

Description

technical field [0001] The invention relates to the field of electronic device detection, in particular to an automatic detection method for a controller. Background technique [0002] An electrical product has gone through schematic design, PCB design, software design, proofing verification, small batch production and mass production, problem feedback, product improvement and other links to get a truly qualified product. [0003] In the production process, how to quickly and reliably detect whether a product meets the product requirements is a difficult problem. In electronic products for new energy applications (including: photovoltaic controllers, wind turbine controllers, wind and solar hybrid controllers, step-up controllers, step-down controllers, etc.), there are a wide variety of products, combining software and hardware. In the production process, ordinary manufacturers basically rely on people to visually inspect the appearance; in terms of function inspection, th...

Problems solved by technology

[0005] 1. All controllers rely on manual power-on detection one by one, and every time a function is detected, a wiring method must be replaced. Manual detection is very time-consuming

[0006] 2. Equipped with 30 inspection workers every day, only about 800 controllers can be inspected every day. After manual inspection and random inspection before storage, there will be a defect rate of 1%.

[0007] 3. Due to the need for a large number of production personnel, the cost of the product remains high, resulting in a decline in product competitiveness

[0008] 4. Product production management is chaotic, it is difficult to trace and track
