Embodiment Construction

[0055] Before introducing the embodiments of the present invention in detail, some terms in the embodiments of the present invention are explained below, so as to facilitate the understanding of those skilled in the art.

[0056] 1. OTG technology

[0057] OTG technology is mainly used in the connection and data transmission between various mobile devices such as mobile phones.

[0058] The interface of the USB connector is a master-slave interface. There must be a host device, that is, a Host, for data transmission, and the USB OTG technology is to realize data transmission between devices without a Host. When a terminal supporting the USB OTG function (i.e., the terminal device described in the embodiment of the present invention) is used alone, it is in the Device (Device) state, and the device type identification (Identity, ID) in the USB standard signal will be pulled down when the OTG device is connected. The signal makes the terminal device switch from the Device state...

Abstract

The invention provides an OTG function detection method, system, device and equipment, automatic OTG function detection can be executed by an upper computer, and the method comprises the steps that the upper computer sends a first control instruction to first equipment to be detected and second equipment to be detected, the first control instruction is used for configuring the first to-be-tested equipment as power supply equipment and the second to-be-tested equipment as power receiving equipment, and a USB interface of the first to-be-tested equipment is connected with a USB interface of the second to-be-tested equipment through a USBOTG line. The upper computer receives a first detection signal from the first to-be-detected device through the first transmission line, and receives a second detection signal from the second to-be-detected device through the second transmission line; and determines whether the OTG function of the first transmission direction of the USBOTG line is normal or not according to the first detection signal and the second detection signal. According to the method, the problems of relatively low efficiency and high detection cost of an OTG function test scheme can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to an OTG function detection method, system, device and equipment. Background technique [0002] At present, USB interfaces on mobile terminals such as mobile phones and smart watches are very popular. The development of USB technology enables personal computers (personal computers, PCs) and other devices to connect devices with various data transmission speeds together in a simple manner and at a moderate manufacturing cost. The universal serial bus (universal serial bus, USB) on-the-go interface protocol (on the go, OTG) technology is to realize data transmission between devices without a host device (Host). Through the OTG technology, USB interface accessories can be extended for the mobile terminal to enrich the functions of the mobile terminal. [0003] In order to determine the performance of the data transmission path between hardware devices in the production process of t...
