The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

Embodiment one

Please refer to FIG. 1. FIG. 1 is a schematic flow diagram of a method for detecting a touch screen of a complete machine disclosed in an embodiment of the present invention; as shown in FIG. 1, a method for detecting a touch screen of a complete machine may include:

101. After the touch screen detection device of the whole machine is connected to the touch screen through the OTG connection line, the screen is stuck or the faulty machine to be tested is invalid, and the touch screen of the faulty machine to be tested is touched, the touch screen detection device of the whole machine reads the fault to be tested The touch screen device file used to record the corresponding event information of the touch screen in the machine;

The touch screen detection device of the whole machine is provided with a USB interface, and the faulty machine to be tested is also provided with a USB interface. Implement the USB-OTG mode with the faulty machine to be tested, so that the touch screen detection device of the whole machine can read data from the faulty machine to be tested based on the OTG function. Wherein, the faulty machine to be tested has problems such as a stuck or invalid touch screen, and the embodiments of the present invention can quickly identify whether the stuck or disabled screen is caused by hardware or software.

As an optional implementation, after the touch screen detection device of the whole machine is connected to the touch screen through the OTG connection line and the screen is stuck or the faulty machine to be tested is invalid, and the touch screen of the faulty machine to be tested is touched, the touch screen of the whole machine The detection device reads the touch screen device file used to record the corresponding event information of the touch screen in the faulty machine to be tested. The touch screen includes the touch screen being slid and/or the virtual key on the touch screen being pressed (click or double click, etc.), the touch screen device Files include dev files, input files and eventX files.

Among them, after the touch screen detection device of the whole machine is connected to the touch screen through the OTG connection line and the screen is stuck or the faulty machine to be tested is invalid, the touch screen of the faulty machine to be tested is touched (slide on the touch screen to get the movement track or click on the virtual button), because the touch screen is stuck or invalid, if the faulty machine to be tested is not a failure of the touch screen hardware itself, it will detect that it is touched, and will record the event information in the dev file, input file and eventX file to update the dev file, input file, and eventX file, the number of bytes in the dev file, input file, and eventX file is not zero; if the touch screen hardware itself fails, the faulty machine under test cannot detect that the touch screen is touched, and will not update the dev file, input file and eventX file, then the number of bytes in the dev file, input file, and eventX file is zero.

When the touch screen of the faulty machine to be tested is in an invalid state or the screen is stuck, if the touch screen of the faulty machine to be tested is in the process of being touched, if the touch screen hardware itself is not faulty, it will be able to detect the position of the force-bearing area of the touch screen when being touched , force duration and force magnitude, etc. The touch screen of the faulty machine to be tested supports multi-touch technology. After the touch screen detection device of the whole machine is connected to the touch screen through the OTG cable and the screen is stuck or the faulty machine to be tested is invalid, when the tester touches the touch screen, the fault to be tested The machine performs mutual-capacitive touch detection and self-capacitive touch detection on the touch screen, and obtains the mutual-capacitive touch detection results and self-capacitive touch detection results respectively. Arithmetic operations are performed on the detection results to obtain the position of the touched force-bearing area. The time detection device starts timing when the touch is detected, and ends the timing when the touch disappears, so as to obtain the force duration. The faulty machine to be tested can detect the force on the touch screen through the sensor.

As an optional implementation, after the touch screen detection device of the whole machine is connected to the touch screen through the OTG connection line and the screen is stuck or the faulty machine to be tested is invalid, the touch screen detection device of the whole machine detects whether it has received the successful message sent by the faulty machine to be tested. Connection indication; if the successful connection indication sent by the faulty machine to be tested is received, and the touch screen of the faulty machine to be tested is touched, the touch screen detection device of the whole machine executes and reads the event information used to record the corresponding event information of the touch screen in the faulty machine to be tested. Steps for touchscreen device files.

Among them, after the touch screen detection device of the whole machine is connected to the touch screen through the OTG connection line and the screen is stuck or the faulty machine to be tested is invalid, the touch screen of the faulty machine to be tested is touched (slide on the touch screen to get the moving track or click on the virtual button) , because the touch screen is stuck or invalid, if the faulty machine to be tested is not a failure of the touch screen hardware itself, it will detect being touched, and will record the event information in the dev file, input file and eventX file, thereby updating the dev file, The number of bytes in the input file and eventX file, dev file, input file, and eventX file is not zero; if the touch screen hardware itself fails, the faulty machine to be tested cannot detect that the touch screen is touched, and will not update the dev file and input file and eventX files, then the number of bytes in dev files, input files, and eventX files is zero.

When the touch screen of the faulty machine to be tested is in an invalid state or the screen is stuck, if the touch screen of the faulty machine to be tested is in the process of being touched, if the touch screen hardware itself is not faulty, it will be able to detect the position of the force-bearing area of the touch screen when being touched , force duration and force magnitude, etc. The touch screen of the faulty machine to be tested supports multi-touch technology. After the touch screen detection device of the whole machine is connected to the touch screen through the OTG cable and the screen is stuck or the faulty machine to be tested is invalid, when the tester touches the touch screen, the fault to be tested The machine performs mutual-capacitive touch detection and self-capacitive touch detection on the touch screen, and obtains the mutual-capacitive touch detection results and self-capacitive touch detection results respectively. Arithmetic operations are performed on the detection results to obtain the position of the touched force-bearing area. The time detection device starts timing when the touch is detected, and ends the timing when the touch disappears, so as to obtain the force duration. The faulty machine to be tested can detect the force on the touch screen through the sensor.
