[0044] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0045] Figure 1 It is a logical structure block diagram of the system for locating the cause of touch abnormality on the touch screen 2 of the present invention, including a cockpit domain controller 1, a touch screen 2, a serial port 3, a host computer 4 and a server 5, wherein the cockpit domain controller 1 is connected to the touch screen 2; the touch screen 2 is connected to the host computer 4 through the serial port 3; the server 5 is connected to the host computer 4 through a wireless network.

[0046] Figure 2 This is a principle structure diagram of the system for locating the cause of the touch abnormality on the touch screen 2 of the present invention. Figure 2As can be seen, the touch screen 2 includes a touch chip 21 and a microcontroller (MCU) 22, and the touch chip 21 is connected to the microcontroller (MCU) 22; the microcontroller (MCU) 22 is connected to the cockpit domain controller 1 and the serial port 3 respectively.

[0047] Combine the following Figure 1 and Figure 2 The working principle of the system of the present invention is introduced as follows:

[0048] The touch chip 21 generally has a normal reporting state and a fault state. In the normal reporting state, the touch chip 21 will scan the touch data on the touch screen 2, such as pressing, moving, and releasing the finger on the touch screen 2, and then the touch chip 21 will input the touch data to the microcontroller (MCU) 22 through the IIC; and the fault state generally means that the touch chip 21 detects a fault, such as an open circuit in the circuit, and the touch chip 21 will report the fault data to the microcontroller (MCU) 22.

[0049] After the touch chip 21 scans the touch data on the touch screen 2, the touch data is input to the microcontroller (MCU) 22 through the touch chip 21. Specifically, when the touch chip 21 scans the touch data on the touch screen 2 and reports the touch data to the microcontroller (MCU) 22, the touch chip 21 pulls the interrupt pin of the microcontroller (MCU) 22 to notify the microcontroller (MCU) 22 to read the touch data.

[0050] After the microcontroller (MCU) 22 has read the touch data, the microcontroller (MCU) 22 inputs the touch data to the host computer 4, and the microcontroller (MCU) 22 parses the touch data and inputs the parsed touch data to the host computer 4. Specifically, after the microcontroller (MCU) 22 has read the touch data, the microcontroller (MCU) 22 inputs the interrupt and touch data to the host computer 4 in real time through the serial port 3. The host computer 4 defines a unified standard touch object format. After the host computer 4 receives the touch data, it will parse the touch data into the standard format defined internally according to the format required in the document of the touch chip 21 for standby use. (The touch document of the touch chip 21 specifies its point reporting analysis. For example, in a frame of IIC data, the first byte is the number of fingers, the second byte is the state of the touching finger - pressed / moved / released, the third byte is the X coordinate value, and the fourth byte is the Y coordinate value.) In addition, the microcontroller (MCU) 22 will also parse the touch data into data of a specified format according to the document required by the customer, and then the microcontroller (MCU) 22 will pull down the interrupt of the cockpit domain controller 1 to notify the cockpit domain controller 1 to read the data of the specified format parsed by the microcontroller (MCU) 22 according to the document required by the customer. In addition, the microcontroller (MCU) 22 will also notify the host computer 4 of the interrupt event of pulling down the cockpit domain controller 1 through the serial port 3. When the cockpit domain controller 1 reads the data of the specified format parsed by the microcontroller (MCU) 22 according to the document required by the customer, the microcontroller (MCU) 22 sends the data of the specified format parsed by the microcontroller (MCU) 22 according to the document required by the customer to the host computer 4 through the serial port 3.

[0051] After the host computer 4 receives the touch data, the host computer 4 parses the touch data into standard data and determines whether the touch data parsed by the microcontroller (MCU) 22 is the same as the standard data; if the host computer 4 determines that the touch data parsed by the microcontroller (MCU) 22 is not the same as the standard data, the server 5 performs a first pop-up window prompt; if the host computer 4 determines that the touch data parsed by the microcontroller (MCU) 22 is the same as the standard data, the host computer 4 inputs the standard data to the server 5. Specifically, according to the documents of most touch chips 21 and the point reporting protocol defined by the customer, it can be abstracted as follows: Figure 4The parameter fields shown are filled in according to the specific project, and then handed over to the host computer 4 for loading. The host computer 4 will parse the received touch data according to the configuration items. The data after the host computer 4 parses the received touch data according to the configuration items is called standard data, and the host computer 4 will determine whether the data in the specified format parsed by the microcontroller (MCU) 22 according to the document required by the customer is the same as the standard data. If not, the first pop-up window prompt is made through the server 5; if the same, the host computer 4 inputs the standard data to the server 5. Among them, the content of the first pop-up window prompt is that the microcontroller (MCU) 22 parses incorrectly, that is, it is located that the cause of the touch abnormality of the touch screen 2 is the error in the parsing of the touch data by the microcontroller (MCU) 22. In addition, the host computer 4 will also ensure or locate the path status of the entire link reported by the touch according to the status of the interrupt event.

[0052] After the upper computer 4 inputs the standard data into the server 5, the server 5 draws the touch trajectory according to the standard data and determines whether there is any illogical reporting data; if the server 5 determines that there is any illogical reporting data, the server 5 performs a second pop-up window prompt; if the server 5 determines that there is no illogical reporting data, the server 5 does not perform a second pop-up window prompt. Specifically, when the host computer 4 is started, the host computer 4 will actively register with the server 5. After the registration is successful, the host computer 4 will submit the standard data to the server 5. At this time, one or more users can access the server 5 through the browser. The server 5 will draw the touch track on the browser interface according to the standard data. While the server 5 draws the touch track on the browser interface according to the standard data, the server 5 can also determine whether there is illogical reporting data in the standard data. When the server 5 determines that there is illogical reporting data in the standard data, the server 5 will perform a second pop-up window prompt. For example, when it is determined that the coordinates of the reporting point exceed the effective definition range of the touch coordinates, or the changes of pressing, moving, and releasing in the touch event are illogical, or when sliding, the span of the two coordinate points is large, and it is obviously not a touch track that can be operated by humans, the second pop-up window prompt will be performed; when the server 5 determines that there is no illogical reporting data in the standard data, the server 5 will not perform the second pop-up window prompt. Among them, the content of the second pop-up window prompt is that the touch chip 21 is wrong, that is, the cause of the touch abnormality of the touch screen 2 is located to be the error of the touch chip 21.

[0055] S2: inputting touch data to the host computer 4 through the microcontroller (MCU) 22 , parsing the touch data through the microcontroller (MCU) 22 , and inputting the parsed touch data to the host computer 4 . Specifically, after the microcontroller (MCU) 22 reads the touch data, the microcontroller (MCU) 22 inputs the interrupt and touch data to the host computer 4 in real time through the serial port 3, and the microcontroller (MCU) 22 will also parse the touch data into data in a specified format according to the document required by the customer, and then the microcontroller (MCU) 22 pulls down the interrupt notification of the cockpit domain controller 1 to read the data in the specified format parsed by the microcontroller (MCU) 22 according to the document required by the customer. In addition, the microcontroller (MCU) 22 will also pull down the interrupt event of the cockpit domain controller 1 to notify the host computer 4 through the serial port 3. When the cockpit domain controller 1 reads the data in the specified format parsed by the microcontroller (MCU) 22 according to the document required by the customer, the microcontroller (MCU) 22 sends the data in the specified format parsed by the microcontroller (MCU) 22 according to the document required by the customer to the host computer 4 through the serial port 3.

[0058] S5: The server 5 performs a first pop-up window prompt. Specifically, if the result determined by the host computer 4 in S4 is different, the server 5 performs a first pop-up window prompt. The content of the first pop-up window prompt is that the microcontroller (MCU) 22 has an error in parsing, that is, the cause of the touch abnormality on the touch screen 2 is an error in parsing the touch data by the microcontroller (MCU) 22.

[0059] S6: The host computer 4 inputs the standard data to the server 5. Specifically, if the result determined by the host computer 4 in S4 is the same, the host computer 4 inputs the standard data to the server 5.

After the registration is successful, the host computer 4 will submit the standard data to the server 5. At this time, one or more users can access the server 5 through the browser, and the server 5 will draw the touch track on the browser interface according to the standard data.

[0061] S8: The server 5 determines whether there is any illogical reporting data; if so, the process proceeds to S9; if not, the process proceeds to S10. Specifically, while the server 5 draws the touch track on the browser interface according to the standard data, the server 5 can also determine whether there is any illogical reporting data in the standard data; if so, the process proceeds to S9; if not, the process proceeds to S10.

[0062] S9: The server 5 performs a second pop-up window prompt. Specifically, when the server 5 determines in S8 that there is illogical reporting data in the standard data, the server 5 performs a second pop-up window prompt. The second pop-up window prompt is that the touch chip 21 has an error, that is, the cause of the touch abnormality of the touch screen 2 is located to be an error in the touch chip 21.

[0063] S10: The server 5 does not issue a second pop-up window prompt. Specifically, when the server 5 determines in S8 that there is no illogical reporting point data in the standard data, the server 5 does not issue a second pop-up window prompt.
