Problems solved by technology

However, this method cannot detect the problem of empty soldering of the configuration channel or short circuit to the high level, and the test effect is poor
[0004] In addition, the existing test methods for configuring channels generally require manual operation to complete the test, which not only has human error, high labor cost, but also low test efficiency, which is not conducive to the actual production of large quantities

Embodiment Construction

[0050] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0051] The current method for testing the configuration channels in the USB interface is to detect the signal states of the configuration channels (CC1 and CC2) respectively by inserting the front and back of the USB interface at different stations. However, this method cannot detect the problem of empty soldering of the configuration channel or short circuit to the high level, and the test effect is poor.

[0052] In addition, the existing test methods for configuring channels generally require manual operation to complete the test, which not only has human error, high labor cost, but also low test efficiency, which is not conducive to actual mass production.

[0053] For this reason, the application proposes a test method, device, equipment and test system for configuration chann...

Abstract

The embodiment of the invention provides a test method, device, equipment and system for a configuration channel, the method is applied to first equipment, and the method comprises the steps: sending a forbidding instruction to second equipment, wherein the forbidding instruction is used for indicating the second equipment to forbid responding to a signal of the configuration channel; accessing the configuration channel to a first circuit in a control circuit, and sending a first request to the second device, the first request being used for requesting to obtain a first signal of the configuration channel; receiving a first signal of the configuration channel sent by the second device; connecting the configuration channel to a second circuit in the control circuit, sending a second request to the second device, wherein the second request is used for requesting to obtain a second signal of the configuration channel; receiving a second signal of the configuration channel sent by the second device; and determining the state of the configuration channel based on the first signal and the second signal.

Description

technical field [0001] The present application relates to the technical field of configuration channel testing, and in particular to a testing method, device, equipment and system for configuration channels. Background technique [0002] In the manufacturing process of electronic products such as mobile phones and computers that support Universal Serial Bus (Universal Serial Nus, referred to as USB) interface (such as USB Type-C interface, etc.), the configuration channel (Configuration Channel, referred to as CC in the USB interface, Such as CC1 and CC2, etc.) for state testing is an important link. [0003] However, the current method for testing the configuration channels in the USB interface is to detect the states of the configuration channels (CC1 and CC2) respectively by plugging the USB ports forward and backward at different stations. However, this method cannot detect the problem of empty soldering of the configuration channel or short circuit to the high level, a...
