Detailed Description
Before describing the embodiments of the present invention in detail, some terms used in the embodiments of the present invention will be explained below to facilitate understanding by those skilled in the art.
1. OTG technology
The OTG technology is mainly applied to connection and data transmission between various mobile devices such as mobile phones.
The interface of the USB connector is a master-slave interface, and a Host device, i.e. Host, is required for data transmission, while the USB OTG technology realizes data transmission between devices without 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, the terminal Device is in a Device (Device) state, and when the OTG Device is accessed, a Device type Identifier (ID) signal in the USB standard signal is pulled low, so that the terminal Device is switched from the Device state to a Host state, and interaction between the two devices can be further achieved.
2. Universal Serial Bus (USB)
USB is an external bus standard used to standardize the connection and communication between computers and external devices. Is an interface technology applied in the field of PC. The USB interface mainly exists in the following three types: a Standard Downlink Port (SDP), a Dedicated Charging Port (DCP), and a Charging Downlink Port (CDP).
Five pins of the USB interface are VCC, UD-, UD +, ID and GND respectively, and can be classified into three types: power supply line, data line and OTG status line. The USB line signal compound switch is responsible for controlling the on-off or off of a power supply line and a data line in the USB interface, and the OTG state line is directly controlled by the main control chip so as to realize the effect of switching the OTG mode.
At present, by using the OTG technology, a mobile phone is directly connected to USB external devices such as a USB flash disk, an MP3, a keyboard, and a game pad to perform functions such as data line transmission, input operation, or charging without using a computer as a transfer station. As shown in fig. 1, an OTG line is directly connected to the mobile phone and the usb disk, and the mobile phone can read information in the usb disk and copy a transfer file, which is equivalent to that the usb disk can be used for capacity expansion of the mobile phone. Therefore, when the user travels outside, the user can only take one OTG line and one large-capacity U disk. The picture is taken, the picture is copied to the U disk at night, and the mobile phone has enough space to take a new picture the next day. In addition, under outdoor or the scene that is difficult to find fixed socket, utilize the OTG technique, can realize the purpose of mutual filling between two electronic equipment through connecting the go, OTG. Carry out mutual charging between the different electronic equipment through the OTG, connect two electronic equipment through the charging wire, manual operation selects an electronic equipment as power supply unit, and another electronic equipment is as the powered device. Therefore, it is necessary to detect the OTG function. Before USB interfaces in products such as mobile phones, tablet computers, digital cameras and printers are connected with external equipment, in order to ensure the accuracy of the USB transmission data direction of the products and ensure that the OTG of each USB product after testing is normal, the PCBA after mounting needs to be subjected to board level judgment. The USB device is divided into a master device and a slave device, and data transmission can be realized only when one master device is connected to one slave device, and the OTG device can serve as both the master device and the slave device, so that the accuracy of the USB data transmission function when one USB device serves as the master device or the slave device needs to be verified.
The current OTG test system is limited to test through an external switch device and a switching control device, and in addition, when the OTG function is verified, other host and slave devices need to be externally connected and replaced, a plurality of cables need to be manually plugged, and the requirement of rapid test cannot be met. After the components and parts paster is completed in the paster factory, the reliability of the paster needs to be quickly determined, the OTG function is critically important to detect, a large amount of time is spent in the manual testing process, and the accuracy of the OTG function in a hardware system is not favorably and quickly detected.
Therefore, the invention provides the OTG function detection method, the method can be used for mutually connecting the two devices to be detected through the USBOTG line without the help of switching equipment, a relay or a switch element, and the charging or power receiving master-slave relation between the two devices to be detected is controlled by the upper computer, so that the accuracy of the USB data transmission function when the devices to be detected are used as master devices or slave devices is verified. According to the method, the equipment is connected and disconnected without manual plugging or external switches, and the detection processing of the bidirectional transmission capability of the OTG function of the equipment to be detected can be completed in a full-automatic detection process.
