Abstract

The invention provides a product testing system comprising a power circuit, a processing circuit, a multi-path selection circuit, an acquisition circuit and a communication circuit. The processing circuit is configured to generate a test signal and send the test signal to a to-be-tested circuit board. The input terminal of the multi-path selection circuit is connected with the to-be-tested circuitboard; the output terminal of the to-be-tested circuit board is connected with the input terminal of the acquisition circuit; one path of the multi-path selection circuit is corresponds to one path of signal in the to-be-tested circuit board; and the output terminal of the acquisition circuit is connected with an acquisition terminal of the processing circuit. The processing circuit is also usedfor determining whether an output signal is correct based on a digital signal, generating a corresponding test result, and sending the test result to an external device through the communication circuit. With the provided product testing system, the port resources of the processing circuit are saved; the number of the acquisition circuits is reduced; the cost is saved; the use efficiency of the acquisition circuit is improved; and the testing efficiency and the testing accuracy are enhanced.

Description

technical field [0001] The present invention relates to the technical field of product testing, in particular to a product testing system. Background technique [0002] At present, the smart lamps produced on the market are all embedded with core circuit boards. After these circuit boards are produced, they need to be tested before they can be assembled into the lamps. Therefore, the testing process is very important, which is related to the performance of the product. At present, manual testing is generally used, and manual testing is likely to cause errors, and the accuracy of testing is poor. Contents of the invention [0003] In order to solve the above problems, the purpose of the embodiments of the present invention is to provide a product testing system. [0004] An embodiment of the present invention provides a product testing system, including: a power supply circuit, a processing circuit, a multiplexing circuit, an acquisition circuit and a communication circuit...
