Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted voltage detection, 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 have higher and higher requirements for in-car entertainment, there are plans to install in-car game consoles in vehicles. The in-car game consoles may be such as Metaverse in-car game consoles. Among them, the Metaverse in-car game console can display a three-dimensional virtual space that is different from the current real world and created through interactive technology. In such a space, a virtual identity can be created through technologies such as virtual reality and augmented reality. Through such a virtual identity, various activities such as socializing, production, consumption, and entertainment can be carried out in the three-dimensional virtual space. The Metaverse game console used in the vehicle can enrich the content of the in-car space, making the in-car space a way to access the Metaverse world.

[0003] However, most of the existing game consoles are home consoles, not designed for in-vehicle environments, so there is a lack of voltage detection methods that are compatible with the use environment of in-vehicle consoles. It is understandable that because home game consoles generally have a stable operating environment, the voltage is a stable 220V AC power supply, or 220V AC is converted to DC to provide stable power to the console. There will be no large instantaneous voltage fluctuations or frequent voltage fluctuations in the operating environment of home game consoles. The power supply in the car is not powered by stable AC power, but by the battery in the car, so there will be frequent voltage changes.

[0004] On the other hand, the mains voltage fluctuates based on 220V. Even if the value changes greatly, the fluctuation ratio is smaller than the base voltage of 220V. For example, if the 220V mains voltage fluctuates by 10V, the fluctuation ratio is only about 5%, while the working voltage on the car, for example, 15V, even if it fluctuates by 2V, it exceeds 10%.

[0005] The voltage detection method in the prior art generally detects the voltage of the internal power supply of the game console itself; however, if the console is embedded in a vehicle environment, it is impossible to detect the voltage of the vehicle battery connected to the console. In addition, the power provided by the vehicle battery is too high or too low, which will cause damage to the adapter or the game console. Since the power protection measures are very weak, the console will frequently freeze or fail to start, 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 the fluctuation or drop of the battery voltage on the vehicle and adopt corresponding measures to process it, thereby ensuring the stability of the power supply of the vehicle-mounted game console and improving the user experience.

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

[0016] Among them, further include:

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

[0018] When the transient drop detection module detects that the voltage of the vehicle battery drops, 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 voltage detection processing method for a vehicle-mounted game console is also provided, which is implemented by the aforementioned system, and 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 the transient drop detection module;

[0021] The main control module monitors the voltage of the battery on the vehicle according to the ADC detection module and the transient drop detection module, and when it is detected that the voltage output by the voltage input control module is within a normal range, controls the constant voltage module to start and supply power to each load in the vehicle-mounted game console;

[0022] After the ADC detection module detects that the voltage of the battery on the vehicle 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 that the voltage has dropped, 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] Among them, further include:

[0025] If the main control module detects that the vehicle is in an ignition-off state or a 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 is used to compensate the voltage input by the constant voltage module, and further includes:

[0027] The electric energy for voltage supplement by the voltage compensation module is to supplement the power-deficient voltage to the input voltage of the normal working of the constant voltage module through the boost circuit in the voltage compensation module;

[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] Among them, further include:

[0030] If the ADC detection module detects that the voltage of the vehicle battery rises above a predetermined threshold voltage, 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.

[0031] Correspondingly, as another aspect of the present invention, there is also provided a vehicle-mounted game console, 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, and when the computer program is executed by a processor, the steps of the aforementioned method are implemented.

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

Among them, 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 working power is obtained from the emergency backup power module to maintain the normal operation of the main control module for emergency data storage. Thereby, the stability and reliability of the entire electronic equipment system can be guaranteed, and the user experience effect can be improved.

[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 battery on the vehicle, 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.

For those skilled in the art, without paying creative labor, other drawings obtained based on these drawings still belong to the scope of the present invention.

[0039] Figure 2 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 further described in detail below with reference to the accompanying drawings.

[0041] like Figure 1 As shown, a schematic diagram of the structure of an embodiment of a voltage detection and processing system for a vehicle-mounted game console provided by the present invention is shown; 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 at least includes: 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, and 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 a battery that provides power for the vehicle to travel. At the same time, the on-board battery can also allocate a portion of the electric energy for use by other auxiliary equipment on the vehicle, such as cameras, air conditioners, driving recorders, etc. The on-board game console in the present invention can be a metaverse game console. It is understandable that since the use of electric energy by the on-board game console is relatively complex during operation, it may cause battery voltage fluctuations. Therefore, when the on-board battery is used to power the on-board game console, the battery voltage needs to be detected.

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

[0044] The voltage input control module 16 is arranged between the on-board battery and the ADC detection module 11 and the transient drop detection module 12, and is used to transform the on-board battery voltage after the vehicle is ignited to supply power to the ADC detection module 11 and the transient drop detection module 12; the voltage input control module 16 transforms the on-board battery voltage and can convert the battery voltage into 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 battery on the vehicle and monitor the voltage change occurring during the ADC conversion process;

[0046] The transient drop detection module 12 is used to monitor whether the voltage from the battery on the vehicle 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 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 in 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 a minimum voltage value for the system voltage;

[0048] The voltage compensation module 14 is used to compensate for the deviated voltage of the input constant voltage module when the ADC detection module 11 detects that the voltage of the vehicle battery fluctuates; specifically, the voltage compensation module uses the voltage value of the constant voltage module as a reference to perform 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 value of the power supply; in a specific example, the voltage compensation module 14 can be implemented using a BOOST power supply, such as a power supply with a chip of the MPS MP3428A model;

[0049] The emergency backup power module 15 is used to supply power to the main control module with a backup power supply when the transient drop detection module 12 detects that the voltage of the battery on the vehicle drops; in a specific example, the emergency backup power module 15 can be implemented by a high-voltage LDO MPS MPQ2019 or 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, and is used to receive power from the emergency backup power module 15 and perform emergency storage of data when the transient drop detection module 12 detects that the voltage of the battery on the vehicle drops. Specifically, if the system voltage changes suddenly, the main control module stores important data in the storage module to avoid data loss caused by unstable system power supply; in a specific example, the storage module 17 can use 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 re-powers on and initializes the relevant modules after the vehicle battery voltage returns to normal, and restores the temporarily closed modules to enable them to 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, a variety of 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 more, 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 battery when the engine ACC is ignited, automatically starts and stops, or high-power devices on the vehicle are started, thereby preventing the device from freezing or failing to start, thereby improving the user experience.

[0055] In addition, in the embodiment of the present invention, the transient drop detection module is not directly connected to the battery on the vehicle, but is connected through a voltage input control module. In this way, the operation of 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 transient drop detection module is stopped to reduce static standby loss. In this way, the problem of excessive battery loss on the vehicle caused by long-term parking can be avoided, and the problem of the engine failing to ignite after long-term parking can be avoided, thereby ensuring the stability and reliability of the entire electronic equipment system.

[0056] like Figure 2 As shown, a voltage detection processing method of a vehicle-mounted game console provided by the present invention is shown, which adopts the above-mentioned Figure 1 The described system 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 supplies power to the ADC detection module and the transient drop detection module;

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

[0059] At this time, if no signal is received for the game console to start running, 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 starts 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 battery on the vehicle according to the ADC detection module and the transient drop detection module, and when it is detected that the voltage output by the voltage input control module is within a normal range, controls the constant voltage module to start and supply power to each load in the vehicle-mounted game console;

[0062] Specifically, after the voltage is input to the ADC detection module and the transient drop detection module, the main control module starts to detect the input voltage. When 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 battery on the vehicle 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 the voltage input by the constant voltage module further includes:

[0065] The electric energy for voltage supplement by the voltage compensation module is to supplement the power-deficient voltage to the input voltage of the normal working of the constant voltage module through the boost circuit in the voltage compensation module;

[0066] When the voltage drops and the voltage compensation module performs voltage compensation, the main control module obtains the minimum system working power from the emergency backup power module to maintain the normal operation of the main control module. After the main control module turns on the voltage compensation module, the power supply of the minimum system of the main control module is switched to the constant voltage module, and the emergency backup power module is charged at the same time. If it is detected that the voltage of the battery on the vehicle is stable within the 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.

[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] Step S13, when the transient drop detection module detects that the voltage has dropped, 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. Specifically, if the transient drop detection module detects that the voltage drop rate exceeds the preset rate, emergency storage of data is immediately performed, and important data is written into the storage module to avoid data loss caused by instantaneous voltage changes. It is understandable that the data written into the storage module is customized as needed, for example, the song being played by the music player, the relevant data of the game being run by the game console, the image data collected by the camera, the driving status or parking status of the vehicle, etc.

[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 vehicle battery).

[0070] It can be 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 battery on the vehicle, and are used to cope with the situation where the amplitude of instantaneous fluctuation is not large;

[0071] The transient drop detection is mainly used for instantaneous large fluctuation detection.

[0072] In a specific example, when the ADC detection module detects an instantaneous 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 at this time; if the voltage continues to drop after compensation, it will be detected by the transient drop detection module, and the transient drop detection module 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 the normal operation of the main control module.

[0073] It can be understood that in the embodiment of the present invention, the ADC detection module and the transient drop detection module are not connected to the battery on the vehicle, 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 an ignition-off state or a standby state, the power supply to the ADC detection module or the transient drop detection module is turned off to reduce the power consumption of the battery on the vehicle.
