Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted voltage detection technology, and in particular to providing a voltage detection processing system, method, device and storage medium for a vehicle-mounted game console. Background Art

[0002] As users' demands for in-car entertainment grow, the concept of installing in-car game consoles has emerged. These consoles can be, for example, Metaverse in-car game consoles. Metaverse in-car game consoles can present a three-dimensional virtual space, distinct from the real world, created through interactive technology. In such a space, virtual identities can be created through technologies such as virtual reality and augmented reality. Through these virtual identities, various activities such as socializing, production, consumption, and entertainment can be carried out in the three-dimensional virtual space. Using a Metaverse game console in a car can enrich the content of the in-car space, turning the vehicle's interior into a gateway to the Metaverse world.

[0003] However, most existing game consoles are home consoles and are not designed for in-vehicle environments. Therefore, there is a lack of voltage detection methods that are compatible with the in-vehicle console usage environment. It is understandable that because home game consoles generally operate in a stable environment, the voltage is a stable 220V AC power supply, or 220V AC is converted to DC to provide stable power to the console. The operating environment of home game consoles will not have large instantaneous voltage fluctuations, nor will there be frequent voltage fluctuations. The power supply in the car is not based on stable mains electricity, but on the car's battery, so there will be frequent voltage changes.

[0004] On the other hand, the mains voltage fluctuates based on a base voltage of 220V. Even if the fluctuation is large, the percentage of fluctuation is small compared to the base voltage of 220V. For example, a 10V fluctuation in the 220V mains voltage is only about 5%. However, for a vehicle operating voltage of 15V, even a 2V fluctuation would exceed 10%.

[0005] Existing voltage detection methods typically test the voltage of the game console's internal power supply. However, if the console is embedded in a vehicle, it cannot detect the voltage of the vehicle's battery. Furthermore, excessive or insufficient power from the vehicle's battery can damage the adapter or the game console. Weak power protection measures can also lead to frequent console freezes or inability to boot, resulting in a poor user experience. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the present invention proposes a voltage detection and processing system, method, device and storage medium for a vehicle-mounted game console, which can detect fluctuations or drops in the battery voltage on the vehicle and take corresponding measures to ensure the stability of the power supply of the vehicle-mounted game console and improve the user experience.

[0007] As one aspect of the present invention, a voltage detection and processing system for an in-vehicle game console is provided, which comprises at least: an ADC detection module electrically connected to an on-vehicle battery, a transient drop detection module, a power compensation module, a constant voltage module, and an emergency backup power module; and a main control module electrically connected to both the constant voltage module and the emergency backup power module; wherein:

[0010] The constant voltage module is used to maintain a stable voltage to provide power to the loads in the in-vehicle game console;

[0011] The voltage compensation module is used to compensate for the deviation of the voltage input to the constant voltage module when the ADC detection module detects that the battery voltage on the vehicle fluctuates;

[0012] The emergency backup power module is used to supply power to the main control module with a backup power supply when the transient drop detection module detects a drop in the battery voltage on the vehicle;

[0013] The main control module communicates with the voltage compensation module, ADC detection module, and transient drop detection module, and is used to receive the detection results of the ADC detection module and the transient drop detection module, and control the working status of the voltage compensation module, constant voltage module, and emergency backup power supply module.

[0014] Which further includes:

[0015] The voltage input control module is arranged between the on-board battery and the ADC detection module and the transient drop detection module. It is used to transform the on-board battery voltage after the vehicle is ignited to power the ADC detection module and the transient drop detection module.

[0016] Which further includes:

[0017] The storage module is connected between the main control module and the emergency backup power supply module, and is used to receive power from the emergency backup power supply module and perform emergency storage of data when the transient drop detection module detects that the voltage of the vehicle battery drops.

[0018] Among them, when the transient drop detection module detects that the voltage of the vehicle battery has dropped, the main control module controls the relevant circuit modules that cannot work at low voltage to be protectively shut down, and re-powers on and initializes the relevant modules after the vehicle battery voltage returns to normal.

[0019] Accordingly, as another aspect of the present invention, a method for voltage detection and processing of a vehicle-mounted game console is provided, which is implemented using the aforementioned system. The method comprises the following steps:

[0020] After the main control module detects the vehicle body ignition signal, it controls the voltage input control module to transform the battery voltage on the vehicle and supply power to the ADC detection module and transient drop detection module;

[0021] The main control module monitors the voltage of the vehicle battery according to the ADC detection module and the transient drop detection module. When it is detected that the voltage output by the voltage input control module is within the normal range, the main control module controls the constant voltage module to start and supply power to the loads in the vehicle game console.

[0022] After the ADC detection module detects that the voltage of the vehicle battery fluctuates, the main control module controls the voltage compensation module to compensate the input voltage of the constant voltage module;

[0023] When the transient drop detection module detects a voltage drop, the main control module controls the voltage compensation module to supply power to the storage module and the main control module, and performs emergency storage of data.

[0024] Which further includes:

[0025] If the main control module detects that the vehicle is in the engine-off state or the standby state, the power supply to the ADC detection module or the transient drop detection module is turned off.

[0026] The control voltage compensation module compensates the voltage input by the constant voltage module, further comprising:

[0027] The voltage compensation module uses the voltage boost circuit in the voltage compensation module to supplement the power-deficient voltage to the input voltage of the constant voltage module for normal operation.

[0028] If it is detected that the voltage of the battery on the vehicle is stable within a preset time range, the voltage compensation module is controlled to stop compensation; or, after the rechargeable battery of the voltage compensation module is fully charged, the voltage compensation module is controlled to stop compensation.

[0029] Which further includes:

[0030] If the ADC detection module detects that the voltage of the vehicle battery rises above the predetermined threshold voltage, the main control module turns off the constant voltage module and controls the game console to enter the standby working state, and restarts after recovery.

[0031] Correspondingly, as another aspect of the present invention, a vehicle-mounted game console is provided, which is powered by an on-vehicle power supply and receives an ignition signal from the vehicle, and is provided with the aforementioned voltage detection and processing system.

[0032] Accordingly, as another aspect of the present invention, a computer-readable storage medium is provided, on which a computer program is stored. When the computer program is executed by a processor, the steps of the above-mentioned method are implemented.

[0033] Accordingly, as another aspect of the present invention, a computer program product is provided, comprising computer instructions, wherein the computer instructions instruct a computer device to execute operations corresponding to the aforementioned method.

[0034] The implementation of the embodiments of the present invention has the following beneficial effects:

[0035] The present invention provides a voltage detection and processing system, method, device and storage medium for an in-vehicle game console. In the application scenario of the in-vehicle game console, an ADC detection module and a transient drop detection module are used to detect whether the battery voltage on the vehicle is stable (performing long-term detection and transient detection), and a voltage compensation module, a constant voltage module and an emergency backup module are used to maintain the voltage stability of the in-vehicle host working environment. When voltage fluctuations are detected, the boost circuit of the voltage compensation module is used to supplement the constant voltage module; when it is detected that the power supply drops too much, the minimum system operating power is obtained from the emergency backup power module to maintain the normal operation of the main control module for emergency data storage. This ensures the stability and reliability of the entire electronic equipment system and improves the user experience.

[0036] At the same time, in an embodiment of the present invention, the ADC detection module and the transient drop detection module are not directly connected to the vehicle battery, but are connected through a voltage input control module, so that the operation of the ADC detection module and the transient drop detection module can be controlled by the voltage input control module. In the case of long-term parking, the operation of the ADC detection module and the transient drop detection module can be stopped, which can reduce static standby loss.

[0038] Figure 1 A schematic structural diagram of an embodiment of a voltage detection and processing system for a vehicle-mounted game console provided by the present invention;

[0039] Figure 2 This is a schematic diagram of the main process of an embodiment of a voltage detection and processing method for a vehicle-mounted game console provided by the present invention. DETAILED DESCRIPTION

[0040] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0041] like Figure 1 , which shows a structural schematic diagram of an embodiment of a voltage detection and processing system for a vehicle-mounted game console provided by the present invention; in this embodiment, the vehicle-mounted game console is powered by a vehicle battery 2 (such as a storage battery or a power battery), and the voltage detection and processing system comprises at least: a voltage input control module 16 electrically connected to the vehicle battery, an ADC detection module 11, a transient drop detection module 12, a constant voltage module 13, a power compensation module 14, an emergency backup power module 15, and a storage module 16; a main control module 10 is electrically connected between the constant voltage module 13 and the emergency backup power module 15;

[0042] In the present invention, the on-board battery generally refers to the battery that provides power for the vehicle. At the same time, the on-board battery can also divert a portion of its electrical energy to other auxiliary devices on the vehicle, such as cameras, air conditioners, and driving recorders. The in-vehicle game console in the present invention can be, for example, a Metaverse game console. It is understandable that due to the complex energy usage of an in-vehicle game console during operation, which may cause battery voltage fluctuations, it is necessary to detect the battery voltage when using the on-board battery to power the in-vehicle game console.

[0043] More specifically, in this embodiment, in the voltage detection processing system:

[0044] The voltage input control module 16 is provided between the vehicle battery and the ADC detection module 11 and the transient drop detection module 12. After the vehicle is ignited, the voltage input control module 16 is used to transform the vehicle battery voltage to supply power to the ADC detection module 11 and the transient drop detection module 12. The voltage input control module 16 transforms the vehicle battery voltage to a voltage suitable for the main control module 10.

[0045] The ADC detection module 11 is used to perform ADC conversion (analog to digital conversion) on the voltage from the vehicle battery and monitor the voltage changes that occur during the ADC conversion process;

[0046] The transient drop detection module 12 is used to monitor whether the voltage of the vehicle battery has a transient drop, and also monitor whether a transient rise has occurred. In a specific example, the transient drop detection module 12 can detect the transient drop by using a voltage comparator, and the voltage comparator can be a comparator such as LRC LR431ALT1G;

[0047] The constant voltage module 13 is used to maintain a stable voltage to provide power to other functional modules (i.e., loads) 18 within the vehicle-mounted game console. More specifically, the constant voltage module can be used to maintain a minimum system voltage and provide a reference standard for the minimum voltage value of the system voltage.

[0048] The voltage compensation module 14 is used to compensate for the voltage deviation of the input constant voltage module when the ADC detection module 11 detects a voltage fluctuation in the vehicle battery. Specifically, the voltage compensation module uses the voltage value of the constant voltage module as a reference for voltage compensation. When the output voltage of the vehicle battery is lower than the voltage value of the constant voltage module, the voltage compensation module performs boost compensation to restore the system voltage to the minimum power supply value. In a specific example, the voltage compensation module 14 can be implemented using a BOOST power supply, such as a power supply with an MPS MP3428A chip.

[0049] The emergency backup power module 15 is used to supply power to the main control module using a backup power supply when the transient drop detection module 12 detects a drop in the voltage of the vehicle battery. In a specific example, the emergency backup power module 15 can be implemented using a high-voltage LDO MPS MPQ2019 and a 4700UF aluminum electrolytic capacitor.

[0050] The storage module 17 is connected between the main control module 10 and the emergency backup power module 15. It receives power from the emergency backup power module 15 and performs emergency data storage when the transient drop detection module 12 detects a voltage drop in the vehicle battery. Specifically, if the system voltage suddenly changes, the main control module stores important data in the storage module to prevent data loss due to unstable system power supply. In a specific example, the storage module 17 can be an EEPROM memory.

[0051] The main control module 10 communicates with the storage module 17, the voltage compensation module 14, the ADC detection module 11, and the transient drop detection module 12, and is used to receive the detection results of the ADC detection module 11 and the transient drop detection module 12, and control the working status of the voltage compensation module 14, the constant voltage module 13, and the emergency backup power supply module 15; in a specific example, the main control module 10 can adopt an NXP S32K314 model controller.

[0052] Among them, when the transient drop detection module 12 detects that the voltage of the vehicle battery has dropped, the main control module 10 controls the relevant circuit modules that cannot work at low voltage to be protectively shut down, and after the vehicle battery voltage returns to normal, the relevant modules are powered on and initialized again, and the temporarily closed modules are restored so that they can work normally again in the system.

[0053] In the system provided by the present invention, the voltage input control module 16 provides power to the constant voltage module 13, the ADC detection module 11 and the transient drop detection module 12, and the on-board battery directly supplies power to the voltage compensation module 14. Through this solution, multiple power supply methods are used to ensure stable power supply to each module in the system. Specifically, the on-board battery supplies power to the voltage compensation module 14. When the system voltage fluctuates, the voltage compensation module 14 can correct the fluctuating part; when the on-board battery voltage drops significantly, the constant voltage module 13 is used to maintain the minimum voltage required for stable operation of the system; when the system voltage changes greatly instantaneously, the ADC detection module 11 and the transient drop detection module 12 are used to maintain the stability of the system voltage. In addition, the voltage compensation module 14 and the constant voltage module 13 can also supply power to other functional modules 18 in the system, such as the playback module, image acquisition module, infrared module, calculation processing module, etc.

[0054] The implementation of the present invention can prevent the vehicle-mounted Metaverse game console from experiencing transient voltage drops in the vehicle battery during operations such as engine ACC ignition, automatic start-stop, and startup of high-power devices on the vehicle, thereby improving the user experience.

[0055] Furthermore, in an embodiment of the present invention, the transient drop detection module is not directly connected to the vehicle battery, but rather is connected via a voltage input control module. This allows the voltage input control module to control the operation of the transient drop detection module. During prolonged parking, the transient drop detection module is stopped, reducing static standby power consumption. This prevents excessive battery loss caused by prolonged parking, and further prevents engine ignition failures after prolonged parking, thereby ensuring the stability and reliability of the entire electronic device system.

[0056] like Figure 2 As shown, a voltage detection processing method for a vehicle-mounted game console provided by the present invention is shown, which adopts the above-mentioned Figure 1 The system described is implemented, and the method comprises at least the following steps:

[0057] Step S10: After the main control module detects the vehicle body ignition signal, it controls the voltage input control module to transform the battery voltage on the vehicle and supply power to the ADC detection module and the transient drop detection module;

[0058] Specifically, in step S10 , the main control module starts to start the in-vehicle game console after detecting the vehicle body ignition signal.

[0059] At this time, if the signal for the game console to start running is not received, the main control module maintains a standby state and continues to detect within a preset period.

[0060] If a signal indicating that the game console has started running is received, the main control module sends an instruction to the voltage input control module, requesting the voltage input control module to transmit power to the ADC detection module and the transient drop detection module.

[0061] Step S11: The main control module monitors the voltage of the vehicle battery according to the ADC detection module and the transient drop detection module. When the voltage output by the voltage input control module is detected to be within a normal range, the main control module is controlled to turn on and supply power to the loads in the vehicle game console.

[0062] Specifically, after the voltage is input to the ADC detection module and the transient drop detection module, the main control module begins to detect the input voltage. If the on-board battery voltage monitored by the main control module is normal, it will notify the constant voltage module to start. After the constant voltage module is turned on, the on-board battery input voltage is converted into an adaptive voltage to power other modules, and the game console starts and runs normally.

[0063] Step S12: After the ADC detection module detects that the voltage of the vehicle battery fluctuates, the main control module controls the voltage compensation module to compensate the input voltage of the constant voltage module;

[0064] In a specific example, controlling the voltage compensation module to compensate for the voltage input by the constant voltage module further includes:

[0065] The voltage compensation module uses the voltage boost circuit in the voltage compensation module to supplement the power-deficient voltage to the input voltage of the constant voltage module for normal operation.

[0066] When a voltage drop occurs and the voltage compensation module performs voltage compensation, the main control module draws its minimum system operating power from the emergency backup power module to maintain normal operation. After the main control module activates the voltage compensation module, it switches the main control module's minimum system power supply to the constant voltage module, while simultaneously replenishing the emergency backup power module. If the vehicle's battery voltage remains stable within a preset timeframe, the voltage compensation module ceases compensation. Alternatively, the voltage compensation module ceases compensation after the voltage compensation module's rechargeable battery has fully charged.

[0067] At the same time, if the ADC detection module detects that the voltage of the vehicle battery rises above a predetermined threshold voltage (such as 16V), the main control module turns off the constant voltage module and controls the game console to enter a standby working state, and restarts after recovery.

[0068] In step S13, when the transient sag detection module detects a voltage drop, the main control module controls the voltage compensation module to supply power to the storage module and the main control module, and performs emergency data storage. Specifically, if the transient sag detection module detects that the voltage drop rate exceeds a preset rate, emergency data storage is immediately performed, writing important data to the storage module to prevent data loss caused by transient voltage fluctuations. It will be understood that the data written to the storage module can be customized as needed, for example, including the song currently playing on a music player, data related to the game currently running on a game console, image data captured by a camera, and the vehicle's driving or parking status.

[0069] It can be understood that the electric energy used by the emergency backup power module to compensate for the minimum system power supply voltage of the main control module comes from the voltage maintained by its own energy storage capacitor, or from the voltage of its own button battery, or from its own rechargeable battery (the rechargeable battery is charged by the battery on the vehicle to replenish power).

[0070] It is understood that in the embodiment of the present invention, the ADC detection and compensation steps are used to perform continuous long-term detection of the vehicle battery, and are used to cope with the situation where the instantaneous fluctuation amplitude is not large;

[0071] Transient drop detection is mainly used to detect instantaneous large fluctuations.

[0072] In a specific example, when the ADC detection module detects a momentary drop in voltage, voltage compensation is performed first. If the voltage fluctuation is small at this time, the ADC detection module can complete the voltage fluctuation compensation. If the voltage continues to drop after compensation, it will be detected by the transient drop detection module, which will inform the main control module to perform instantaneous voltage compensation. At this time, the main control module obtains the minimum system operating power supply from the emergency backup power supply module to maintain normal operation of the main control module.

[0073] It is understandable that in the embodiment of the present invention, the ADC detection module and the transient drop detection module are not connected to the vehicle battery, but are connected to the voltage input control module. In this way, the operation of the ADC detection module and the transient drop detection module can be controlled by the voltage input control module. In the case of long-term parking, the operation of the ADC detection module is stopped to reduce static standby loss.

[0074] In a specific example, the method further comprises:

[0075] If the main control module detects that the vehicle is in the off state or standby state, it turns off the power supply to the ADC detection module or the transient drop detection module to reduce the power loss of the vehicle battery.
