Referring to the specific embodiment shown in fig. 1, the invention discloses a method for automatically switching working states of a vehicle-mounted server, which comprises the following steps:
s1, acquiring a current speed value of a vehicle;
in an embodiment, the current speed value comprises an acceleration value and an angular speed value.
Specifically, a current speed value of the vehicle is detected through an IMU (inertial measurement), and then the detected current speed value of the vehicle is transmitted to an MCU (micro controller) in real time, and the MCU records the current speed value to obtain recorded data.
Preferably, the IMU is a sensor.
S2, judging whether the current speed value is larger than a set value or not;
specifically, the set value is 0, that is, the acceleration value and the angular velocity value are both 0.
Specifically, the MCU performs motion analysis based on the recorded data, determines that the vehicle is in a motion state if there is a relative positional deviation of the vehicle (acquired by a positioning or motion sensor) for a period of time, and determines that the vehicle is in a parking state if the vehicle is relatively stationary for a period of time.
S3, if the current speed value is not greater than the set value, the vehicle power supply control line is pulled down, and the current speed value is not greater than the set value and is transmitted to the vehicle-mounted server;
specifically, if the current speed value is not greater than the set value (i.e. the current speed value is 0), the vehicle power control line is pulled down to be 0, then the MCU communicates with the vehicle-mounted server in real time, and the current motion state of the vehicle is transmitted to the vehicle-mounted server in time.
S4, the vehicle-mounted server enters into dormancy operation;
specifically, when the vehicle-mounted server acquires that the vehicle is stationary, the corresponding processing service is stopped, and the vehicle-mounted server enters into a sleep operation, namely, the vehicle-mounted server only sleeps and does not power down.
In an embodiment, after the vehicle-mounted server enters the sleep operation step, the vehicle-mounted server further includes pulling down the vehicle-mounted server power control line to "0", and because both power control lines are "0", the or gate logic is in effect, and the vehicle-mounted server enters the sleep and power-down mode.
Specifically, the working mode of the vehicle-mounted server can be set in advance according to the requirement, namely the vehicle-mounted server is not powered down by dormancy or is powered down by dormancy.
In an embodiment, after the vehicle-mounted server enters the sleep operation, the power supply side output control end takes effect, and the power supply output is turned off, and other power supply outputs except the MCU and the IMU are in a power-down state.
S5, if the current speed value is greater than the set value, pulling up a vehicle power supply control line, and transmitting the current speed value to the vehicle-mounted server, wherein the current speed value is greater than the set value;
specifically, if the current speed value is greater than the set value (i.e. the current speed value is greater than 0), the vehicle power control line is pulled up to be 1, then the MCU communicates with the vehicle-mounted server in real time, and the current motion state of the vehicle is transmitted to the vehicle-mounted server in time.
S6, the vehicle-mounted server enters a working state.
Specifically, after the vehicle-mounted server acquires that the vehicle is changed from a stationary state to a moving state, the door is in action, and the vehicle-mounted server is switched from a dormant state to a working state or the vehicle-mounted server is restarted to be powered on to enter the working state.
In an embodiment, the vehicle-mounted server can be also connected with a vehicle electronic system to acquire the running state of the vehicle in real time; however, the system has the defects that the system needs to be communicated with a vehicle factory, and meanwhile, signal wiring needs to be additionally added, so that the implementation difficulty is high; meanwhile, only the switching between the dormant state and the working state can be solved, and the switching between the power-down state and the working state can not be realized.
The vehicle ACC switch state is not required to be accessed, only a power supply is connected with the interface of the vehicle, the arrangement difficulty of the vehicle-mounted server is simplified, the motion state of the vehicle can be obtained in real time, and a large amount of battery energy is prevented from being consumed when the vehicle stops midway.
