Title:
COMMUNICATION DETECTION METHOD AND APPARATUS, DEVICE, SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/001105
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a communication detection method and apparatus, a device, a system, and a storage medium. The method is applied to a first electronic device, the first electronic device is used for charging a second electronic device, the first electronic device at least comprises a first pin and a second pin, and a first resistor is connected in series between the second pin and the ground. The method comprises: performing transceiving communication with the second electronic device by means of the first pin and the second pin; in the transceiving communication process, detecting a signal level at the second pin; when it is detected that the signal level at the second pin is changed from a high level to a low level, triggering the second pin to start to receive a first data frame; and when a signal level of an identification bit of the first data frame is at a low level, the first electronic device stopping a charging path with the second electronic device, the signal level of the identification bit of the first data frame being used for indicating abnormal data frame communication. Therefore, the detection time can be shortened, and the safety of a charging process can be improved.
