Embodiments provided herein, namely an embodiment of a screen self-healing system.
An embodiment of the present application is described in detail below with reference to fig. 1.
The embodiment of the application provides a screen self-repairing system which comprises a display device and a cabin area control device.
A display device comprising a deserializer configured to receive display information for display by the display device.
In a display system of a vehicle, a plurality of display devices (e.g., a center control display device, an instrument display device) are included. Because the distance between each display device and the cabin area control device is different, in order to ensure that the display information can be effectively displayed on the display screen of the display device, the influence of long distance on the display effect is solved, and each display device comprises: the deserializer and the display processor and the display screen. The display processor is in communication with the deserializer and the display screen, respectively, as shown in fig. 2. The display analog signals transmitted by the coaxial cable or the twisted pair are converted into display analog signals and transmitted to the display processor, the display processor converts the display digital signals of the display screen into display driving signals, and the display driving signals are displayed by the display screen.
The cabin area control device comprises a serializer which is in communication connection with the deserializer, and the cabin area control device is configured to: and in response to the abnormal feedback information obtained from the serializer, repeatedly sending an initialization signal to the communication link of the serializer and the deserializer until the communication link resumes normal communication when the continuous initialization times are less than or equal to the preset initialization times.
Wherein the continuous initialization times refers to the accumulated times of continuous transmission of initialization signals to the communication link.
In the embodiment of the application, the serializer and the deserializer are arranged in pairs, and the deserializer of each display device is provided with a corresponding serializer in the cabin domain control device.
The serializer is configured to convert the display information into a display analog signal for transmission to the deserializer via a coaxial cable or twisted pair.
A cabin area control device (acronym Cockpit Space Center, CSC) is connected with various display devices in the vehicle and displays various alarm information and entertainment information. CSC is one of the large core controllers of the car 4 and all the car models need to be configured. The CSC realizes software and hardware decoupling, is used as a control brain of a display and audio-visual system, supports multi-screen driving, sensor data collection, supports services such as big data, energy management, data management, gateway, diagnosis, air downloading technology and the like, and cooperates with other computing platforms to complete the work of displaying interaction requirements, thereby creating an industry leading cabin intelligent central computing platform.
The abnormal feedback information refers to abnormal information fed back by the communication link of the serializer and the deserializer. The cabin domain control device detects abnormal information of the communication link by monitoring the operation state of the communication link.
Once abnormal feedback information is detected, the cabin domain control device in the embodiment of the application repeatedly sends an initialization signal to the communication link when the continuous initialization times are smaller than or equal to the preset initialization times until the communication link resumes normal communication. Therefore, when the communication link is in a problem, the communication link can restore normal communication in a short period, and the display device can restore normal information display in a short period.
In some embodiments, the cabin area control device further comprises a processing component and an on-chip component, as shown in fig. 2.
A processing component (e.g., a microcontroller unit (english full name Microcontroller Unit, abbreviated MCU)). A processing element is an application specific integrated circuit that typically includes the functions of a processor core, memory, input/output interfaces, and timers. Processing components are commonly used to control small embedded systems, such as sensors, actuators, switches, etc. of automobiles, as well as some simple computing and control tasks. The processing component has lower power consumption and is suitable for real-time control and embedded application. In automobiles, the processing assembly may be used to control simpler functions of door locks, windows, lights, and the like.
The processing component is in communication connection with the on-chip component and the serializer respectively and is configured to: and sending a repair link signal to the on-chip component in response to obtaining abnormal feedback information from the serializer.
In some embodiments, the anomaly feedback information comprises an abort signal or anomaly information of the communication link.
For example, an error signal (such as ERRPIN) pin of the serializer is connected to a first interrupt (such as INT 1) pin of the processing component, and when an abnormality occurs in a communication link between the serializer and the deserializer, the serializer can send an abnormal interrupt signal to the processing component through the connection; alternatively, the processing component obtains detailed information of anomalies of the communication link between the serializer and the deserializer from the serializer via a first bi-directional two-wire synchronous serial bus (i.e., a first I2C bus).
A bidirectional two-wire synchronous serial bus (english full-name Inter-Integrated Circuit, I2C for short), a serial communication protocol, is commonly used to connect a host and a peripheral device, such as a screen. It may transmit low speed data such as configuration settings, control commands, etc.
A serial peripheral interface (english acronym Serial Peripheral interface, abbreviated as SPI) is a synchronous serial peripheral interface that enables an MCU to communicate with various peripheral devices in a serial fashion to exchange information. And only occupy four wires on the pin of chip, saved the pin of chip, save the space for the overall arrangement of circuit simultaneously, provide convenience.
For example, the processing component communicates with the on-chip component through an SPI, and after the processing component obtains abnormal feedback information, a repair link signal is sent to the on-chip component through the SPI.
on-Chip components (SOC for short), SOC is responsible for entertainment domain related functions. The SOC runs the QNX real-time operating system and the android/Linux virtual machine system, and the operating system running on the SOC can meet the functional requirements of entertainment domains, such as functions of telephone, media playing, map positioning, media editing, vehicle setting, reversing images, driving records and the like.
The on-chip component, which is in communication connection with the serializer, is configured to: and in response to receiving the repair link signal, repeatedly sending an initialization signal to the communication link when the continuous initialization times are less than or equal to preset initialization times until the communication link resumes normal communication.
For example, the on-chip component repeatedly sends an initialization signal to the communication link over the second I2C bus.
In some specific embodiments, the on-chip component is configured to repeatedly send an initialization signal to the communication link when the continuous initialization number is less than or equal to a preset initialization number, until the communication link resumes normal communication, including: when the continuous initialization times are smaller than or equal to preset initialization times, judging whether to acquire handshake signals returned by the display device based on the initialization signals after sending the initialization signals to the communication link each time; when the handshake signal is acquired, sending of an initialization signal to the communication link is stopped.
For example, after the on-chip component sends an initialization signal to the communication link, the on-chip component waits for a handshake signal of a second interrupt (such as INT 2) pin returned to the on-chip component by the serializer, if the INT2 pin of the on-chip component obtains the handshake signal, it is determined that the communication link is initialized successfully, the communication link is restored to be normal, and the initialization signal is stopped being sent to the communication link.
In some specific embodiments, after the determining whether to acquire the handshake signal returned by the display device based on the initialization signal, the on-chip component is further configured to: when the handshake signal returned by the display device based on the initialization signal is not acquired, the continuous initialization number of the communication link is increased by one.
The number of consecutive initializations is understood to be the cumulative number of initializations transmitted to the communication link each time after the repair link signal is obtained before the communication link resumes normal communication. When the on-chip component sends an initialization signal to interrupt, it is indicated that the communication link resumes normal communication. As long as the initialization signal is continuously transmitted, it indicates that the communication link does not resume normal communication. The number of consecutive initializations is increased by one before each transmission of an initialization signal. The initial value of the number of consecutive initializations is zero.
For example, the preset initialization number is 3, and the continuous initialization number of the communication link is zero; if the INT2 pin of the on-chip component does not acquire a handshake signal after the on-chip component transmits the initialization signal for the first time, determining that the initialization of the communication link fails, and the communication link is still abnormal, wherein the continuous initialization frequency of the communication link is increased by one, namely the continuous initialization frequency of the communication link is 1; if the INT2 pin of the on-chip component still does not acquire the handshake signal after the on-chip component transmits the initialization signal for the second time, determining that the initialization of the communication link fails, and the communication link is still abnormal, wherein the continuous initialization frequency of the communication link is increased by one, namely the continuous initialization frequency of the communication link is 2; if the INT2 pin of the on-chip component still does not acquire a handshake signal after the on-chip component sends the initialization signal for the third time, determining that the initialization of the communication link fails, and the communication link is still abnormal, wherein the continuous initialization frequency of the communication link is increased by one, namely the continuous initialization frequency of the communication link is 3; if the continuous initialization times of the communication link are greater than the preset initialization times, stopping sending the initialization signals to the communication link; and if the INT2 pin of the on-chip component obtains a handshake signal after the on-chip component sends the initialization signal for the third time, determining that the communication link is successfully initialized, restoring the communication link to be normal, and stopping sending the initialization signal to the communication link.
In some specific embodiments, the on-chip component is further configured to: and in response to receiving the repair link signal, sending a repair failure signal to the processing component when the number of continuous initializations of the communication link is greater than a preset number of initializations.
The processing component is further configured to: and in response to receiving the repair failure signal sent by the on-chip component, sending a reset signal of the on-chip component to the on-chip component, and triggering the on-chip component to reset so as to restore normal communication of the communication link.
In this embodiment, when the communication link between the serializer and the deserializer cannot be repaired by initializing the communication link, the on-chip component notifies the processing component of the repair failure signal. For example, the on-chip component notifies the processing component of the repair failure signal through the SPI.
The processing component sends a reset signal to the on-chip component based on the repair failure signal, resetting the on-chip component to resume normal communication of the communication link.
In some specific embodiments, the on-chip component is further configured to: after the handshake signals are acquired, periodically requesting the display device to return display information of a current screen and first check information of the display information; generating second check-up information based on pre-stored display information of the current screen; and retransmitting pre-stored display information of the current screen when the second check information is not equal to the first check information.
In this embodiment, the handshake signal is obtained, so that it can be determined that the communication link is successfully initialized and the communication link is restored to be normal. It is verified whether the display information of the current screen is normal. The on-chip component periodically sends a screen diagnostic request to a display processor of the display device. The display processor acquires display information from the current screen, and generates first check information of the display information of the current screen based on a preset check rule. The display processor packages and transmits the display information of the current screen and the first verification information of the display information to the on-chip component. For example, if the display information of the current screen is abnormal, the generated first verification information is also abnormal; if the display information of the current screen is normal, the generated first check information is also normal.
The on-chip component pre-stores normal display information (namely pre-stored display information) of the current screen, and generates second check information of the pre-stored display information based on a preset check rule. And determining whether the current screen is normally displayed or not through comparison of the second check information and the first check information. If the second check information is not equal to the first check information, the display of the current screen is abnormal, and the pre-stored display information of the current screen is re-sent, so that the current screen is restored to normal display; if the second check information is equal to the first check information, the current screen display is normal.
According to the embodiment, the on-chip component is used for periodically verifying the display information of the current screen, so that the correctness of the display information of the current screen is ensured. And the potential safety hazard of the vehicle caused by abnormal display is avoided.
