[0002] For 4K monitors, SOC (system-on-chip) usually interacts with the keypad through an RS232 interface (one of the commonly used serial communication interface standards).

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of well-known functions and well-known components.

[0025] like Figure 1 As shown in the figure, the architecture of the operating system corresponding to the existing 4K monitor is shown. The SOC interacts with the keypad through the RS232 interface. For the keypad, since the MCU has fewer pins, it is necessary to connect the IO expansion chip, and then connect to the knob encoder (or button) through the pins of the IO expansion chip.

[0026] like Figure 1 The SOS and MCU shown communicate through the RS232 interface, and the MCU accesses the IO expansion chip through the IIC (bus protocol). The IO expansion chip pins are connected to several buttons and knob encoders. In the high-intensity electrostatic test, an electrostatic gun will be used to shock the key panel part. The solution provided by the embodiment of the present disclosure can effectively solve the problem of abnormal operation of the key panel system caused by high-intensity electrostatic shock.

[0027] The process of a method for processing electrostatic interference provided by the embodiment of the present disclosure is as follows: Figure 2 As shown, steps S201 to S203 are included:

[0028] S201, obtaining current configuration data of the IO expansion chip.

[0029] In specific implementation, the SOC may actively request the keypad to perform a detection operation, for example, the SOC sends a status query command to the keypad, and the keypad will then obtain the current configuration data of the IO expansion chip. Of course, the keypad itself may also perform a detection operation, for example, obtaining the current configuration data of the IO expansion chip according to a predetermined period.

[0030] The above-mentioned current configuration data is usually the value after the IO expansion chip is initialized.

[0031] S202, detecting whether the current configuration data is the same as the initial configuration data of the IO expansion chip.

[0032] In the electrostatic test, the keypad is subjected to momentary high-voltage static electricity, which will cause the IO expansion chip to work abnormally. The phenomenon is that the keypad components other than the IO expansion chip circuit can work normally, but the external devices such as the keys connected to the IO expansion chip cannot work properly. If electrostatic interference occurs, the current configuration data will inevitably be different from the initial configuration data. Therefore, whether the IO expansion chip is in an abnormal working state can be determined by whether the current configuration data is the same as the initial configuration data.

[0033] S203, in the case of different conditions, reconfiguring the IO expansion chip in a predetermined manner so that the predetermined accessories connected to the pin interface of the IO expansion chip are in an enabled state.

[0034] In specific implementation, the above-mentioned reconfiguration of the IO expansion chip in a predetermined manner can be controlled by the SOC, or can be actively executed by the keypad itself. For example, the keypad itself can immediately send a reinitialization command to reinitialize the IO expansion chip, or the SOC can send a reinitialization command to the keypad to reinitialize the IO expansion chip; for another example, the keypad itself can also immediately perform a soft restart, and then soft restart the IO expansion chip, so that each pin interface of the IO expansion chip is restarted. Of course, it can also be a watchdog program set inside the keypad to perform a soft restart at a certain time, and then soft restart the IO expansion chip, so that each pin interface of the IO expansion chip is restarted. The embodiment of the present disclosure does not limit the predetermined method of reconfiguring the IO expansion chip, as long as the reconfiguration of the IO expansion chip can be achieved.

[0035] The disclosed embodiment obtains current configuration data of the IO expansion chip, compares the current configuration data with initial configuration data to determine whether there is electrostatic interference, and reconfigures the IO expansion chip in the presence of electrostatic interference, thereby enabling predetermined accessories externally connected to the pin interface of the IO expansion chip. The problem of the keypad freezing and becoming unusable due to electrostatic interference is solved by reconfiguring the IO expansion chip. The keypad can continue to be used normally with only a simple configuration, thereby improving system performance as a whole.

[0036] The above process is exemplarily described below with reference to the accompanying drawings.

[0037] like Figure 3 As shown, it is a schematic diagram of the interaction situation 1 when both the keypad and the SOC are powered on and running, which includes the following process:

[0038] (1) Send CMD1: SOC sends a command to the keypad, which is used to detect the current status of the keypad.

[0039] (2) Send RESP1: The keypad responds to the self-test, the system is initialized, and if the receiving function is normal, it returns OK; if the IO expansion chip fails to initialize, it returns ERROR.

[0040] (3) Send CMD2: If the previous RESP1 response is OK, the SOC sends an event command to start the keypad workflow; if the previous RESP1 response returns ERROR, the RESRET keypad is reset.

[0041] (4) Send RESP2: The keypad receives the event command and returns OK to the SOC.

[0042] like Figure 4 As shown, it is a second interactive schematic diagram when both the keypad and the SOC are powered on and running, which includes the following process:

[0043] (1) Send CMD1: SOC sends it to the keypad system. This command is used to detect the current status of the keypad.

[0044] (2) After the waiting time for the reply expires, the keypad is reset and the SoC pulls the keypad RESET pin low to achieve reset.

[0045] The disclosed embodiment can continuously monitor the working status of the IO expansion chip at the bottom layer of the program, and reinitialize the chip or soft reset the system according to the current working status of the IO expansion chip.

[0046] In order to further remind the tester of the existence of electrostatic interference, before reconfiguring the IO expansion chip in a predetermined manner, a predetermined prompt message can also be sent to prompt the existence of electrostatic interference, so that when the keypad is in a situation where it cannot be automatically restarted or reset immediately, the electrostatic interference can be manually and actively repaired, providing a better user experience.

[0047] The present disclosure also provides a device for processing electrostatic interference, the structure of which is shown in FIG. Figure 5 As shown, including:

[0048] The acquisition module 10 is used to acquire the current configuration data of the IO expansion chip; the detection module 20 is coupled with the acquisition module 10 and is used to detect whether the current configuration data is the same as the initial configuration data of the IO expansion chip; the reconfiguration module 30 is coupled with the detection module 20 and is used to reconfigure the IO expansion chip in a predetermined manner in the case of a difference, so that the predetermined accessories externally connected to the pin interface of the IO expansion chip are in an enabled state.

[0049] In specific implementation, the SOC may actively request the keypad to perform a detection operation, or the keypad itself may perform the detection operation. Therefore, the acquisition module may be used to: obtain the current configuration data of the IO expansion chip according to a predetermined period; or, in response to a status query command from the SOC, obtain the current configuration data of the IO expansion chip. The current configuration data is usually the value after the IO expansion chip is initialized.

[0050] In the electrostatic test, the keypad is subjected to momentary high-voltage static electricity, which will cause the IO expansion chip to work abnormally. The phenomenon is that the keypad components other than the IO expansion chip circuit can work normally, but the external devices such as the keys connected to the IO expansion chip cannot work properly. If electrostatic interference occurs, the current configuration data will inevitably be different from the initial configuration data. Therefore, whether the IO expansion chip is in an abnormal working state can be determined by whether the current configuration data is the same as the initial configuration data.

[0051] When the reconfiguration module reconfigures the IO expansion chip in a predetermined manner, it can be controlled by the SOC or actively executed by the keypad itself. Therefore, the reconfiguration module can be specifically used to: send a reinitialization command to reinitialize the IO expansion chip; or soft restart the IO expansion chip to restart each pin interface of the IO expansion chip.

[0052] In specific implementation, for example, the keypad itself can immediately send a reinitialization command to reinitialize the IO expansion chip, or the SOC can send a reinitialization command to the keypad to reinitialize the IO expansion chip; for another example, the keypad itself can immediately perform a soft restart, and then soft restart the IO expansion chip, so that each pin interface of the IO expansion chip is restarted. Of course, the watchdog program set inside the keypad can also perform a soft restart at a certain time, and then soft restart the IO expansion chip, so that each pin interface of the IO expansion chip is restarted. The embodiments of the present disclosure do not limit the predetermined method of reconfiguring the IO expansion chip, as long as the reconfiguration of the IO expansion chip can be achieved.

[0053] In order to further remind the tester of the existence of electrostatic interference, the embodiment of the present disclosure may also include a reminder module for sending a predetermined reminder message to remind the existence of electrostatic interference. Through the reminder of the reminder module, when the keypad is in a situation where it cannot be automatically restarted or reset immediately, the electrostatic interference can be manually repaired, and the user experience is better.

[0054] The disclosed embodiment obtains current configuration data of the IO expansion chip, compares the current configuration data with the initial configuration data to determine whether there is electrostatic interference, and reconfigures the IO expansion chip in the presence of electrostatic interference, thereby enabling predetermined accessories externally connected to the pin interface of the IO expansion chip. The problem of the keypad freezing and becoming unusable due to electrostatic interference is solved by reconfiguring the IO expansion chip. The keypad can continue to be used normally with only a simple configuration, thereby improving system performance as a whole.
