Description
Technical Field
The present application relates to the field of vehicle terminals, and more particularly, to a vehicle TBOX, a method for reducing energy consumption thereof, and a computer-readable storage medium.
Background
In order to complete data interaction with a platform, a built-in MODEM with a wireless mobile network communication function is arranged in a vehicle-mounted TBOX device, and under a normal condition, vehicle data acquired by the TBOX device are sent to the side of the platform through the MODEM; and meanwhile, receiving a control instruction at the platform side, executing and feeding back a result to the platform. The vehicle-mounted TBOX is generally provided with a spare battery with a small capacity so as to maintain communication continuity for a certain time in an emergency. Most TBOX uses a vehicle battery.
Under the condition that a vehicle normally runs, the power consumption condition of the TBOX does not need to be paid special attention, but when the vehicle is flamed out and is static, the power consumption control of the TBOX is particularly important, and if the power consumption control of the TBOX is improper, the electric quantity of a vehicle storage battery can be exhausted, further, the vehicle cannot be ignited, and the use of the vehicle is seriously influenced. To control the power consumption of the vehicle when turned off, TBOX sets different operating modes, generally classified into an operating mode, a standby mode, and a sleep mode. Under the condition of the working mode, the TBOX normally works without paying special attention to power consumption; the MODEM can be completely closed in the sleep mode without any network interaction, and the overall power consumption of the TBOX is very low; it should be noted that in the standby mode, the wireless network function of the MODEM is not turned off, and only data communication is no longer used, but the MODEM normally resides in the mobile network and can receive the short message sent by the platform side. While it generally takes a long time (e.g., 72 hours) to switch the standby mode to the sleep mode, power consumption control of the standby mode is important.
In a normal network condition, the MODEM resides in the mobile network, and the power consumption is relatively low when data service is not performed, but if there is no network signal in the vehicle location or the network signal is weak, the MODEM frequently initiates network finding, registration and switching, and the power consumption is relatively high in this case. Under the current environmental conditions, the underground garages of common cells generally have no mobile network signal coverage, and vehicles of users generally stop at specific parking spaces. This has the problem mentioned above that each time a vehicle enters a cell garage, stops at a particular parking space and stalls, the power consumption of the vehicle TBOX is high after switching from the operating mode to the standby mode because there is no network or the signal is weak. In this case, the control of power consumption is completely realized by network searching and network parking optimization of a MODEM chip manufacturer, and the vehicle-mounted TBOX does not have a good method or measure for controlling power consumption.

The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
Example one
In normal running of the vehicle, the vehicle-mounted TBOX uses a vehicle battery, and it is generally unnecessary to pay special attention to power consumption of the vehicle-mounted TBOX. The embodiment of the application focuses on the road conditions of basements such as a parking lot and the like, and the working mode of the vehicle-mounted TBOX is assumed under the condition that both position signals and network signals of the parking lot are poor.
As shown in fig. 1, a method for reducing power consumption of a vehicle TBOX, provided by an embodiment of the present application, includes a processor and a modem connected to the processor, and operating modes of the vehicle TBOX include an operating mode, a standby mode and a sleep mode, and the method includes:
step 1, detecting the real-time position of a vehicle;
the vehicle real-time location can be detected by a location module of the on-board TBOX, such as a GPS module or a beidou module.
And 2, when the real-time position of the vehicle is within the error range of the preset position, the processor switches the mode of the vehicle-mounted TBOX to a sleep mode so as to close the modem to stop the network searching and network parking operation of the modem.
The preset position refers to a preset position of a parking lot or a position of a fixed parking space. The error range of the preset position refers to a position of arriving at an entrance of a parking lot, or a position of 50 m, 100 m, 200 m or 300 m from a certain fixed parking space, and is preset according to specific situations, or a record is stored according to the following historical position information.
When the vehicle reaches the error range of the preset position, the vehicle-mounted TBOX enters the sleep mode, and the modem is turned off, so that the frequent network searching, registering and switching operations under the condition of poor network state or no network at the preset position of the modem are prevented, the operations with higher power consumption are stopped, the vehicle-mounted TBOX enters the sleep mode, and the overall power consumption of the vehicle-mounted TBOX is reduced.
In some embodiments, as shown in fig. 2, after the step of detecting the real-time position of the vehicle, the method further comprises:
and 21, when the real-time position of the vehicle is within the error range of the preset position and the network state is detected to be a preset state, switching the mode of the vehicle-mounted TBOX to a sleep mode by the processor.
Besides paying attention to the real-time position of the vehicle, the network state in the real-time position needs to be detected and related, so that the detection is more comprehensive, and the subsequent record of historical position information is facilitated. The network state is a preset state, which means that there is no network signal or the network signal is very weak, and the network state may be classified specifically, and this specific implementation manner is not limited in the present application.
Further, after the step of detecting a network status and associating the network status with a real-time location of the vehicle, the method further comprises:
when detecting that the vehicle is flamed out from running, the processor switches the mode of the vehicle-mounted TBOX from the working mode to the standby mode;
when the real-time position of the vehicle is within the error range of the preset position, the processor switches the mode of the vehicle-mounted TBOX from the standby mode to the sleep mode.
Generally, the mode of the vehicle TBOX is an operation mode when the vehicle is normally driven, and the vehicle is switched to the standby mode when the vehicle is turned off, and as described in the background of the present application, it generally takes a long time (for example, 72 hours) to switch the standby mode to the sleep mode, during which the power consumption control of the standby mode is important.
And directly switching the mode of the vehicle-mounted TBOX from the standby mode to the sleep mode without excessive waiting by combining the network state and the real-time position of the vehicle, so as to save energy consumption.
Therefore, in the above situation, since it is known that there is no network condition in the parking lot or parking space, after the vehicle is shut down and enters the standby mode, the vehicle can completely enter the sleep mode directly without performing meaningless switching from the standby mode to the sleep mode with a long duration.
In some embodiments, the method comprises:
when the real-time position of the vehicle meets a position threshold, the processor starts inertial navigation; or
When the position signal for detecting the real-time position of the vehicle is reduced to a first preset intensity and the network signal for detecting the network state is reduced to a second preset intensity, the processor starts inertial navigation.
The position threshold may be set to the parking lot entrance position, or a position 5 meters, 10 meters, 50 meters, or 100 meters of the entrance position, and may be set specifically according to the positioning accuracy and the user requirement. The position signal is reduced to the first preset strength, which means that the position signal is weak enough to guide the navigation of the vehicle, and can be set according to the prior art; the second preset strength of the network signal also refers to a state where the network signal is weak enough to guide vehicle navigation, and may be set according to the prior art, and according to the network signal strength level, the signal-to-noise ratio, the current network registration state, and the like, it is determined whether the network signal belongs to a network unregisterable state, or a strength equal to the preset strength of the network state, which is not limited in this application.
The inertial navigation is a navigation for a parking lot vehicle to travel to a parking space. Specifically, parking lot data may be received in advance; and generating an inertial navigation scheme for the inertial navigation according to the parking lot data and the preset position. The parking lot data refers to the summary of information such as the area of a parking lot, the positions of an entrance and an exit of the parking lot, a parking space division diagram, a driving route and the like.
Aiming at the identification of the vehicle position, the network and position module is normally used outdoors for positioning, but network signals and position signals can be uncovered after entering an underground garage, so that the inertial navigation is considered to be used in the stage to perform the positioning in the final stage.
Further, after the step of the processor turning on inertial navigation, the method further comprises:
recording the detected nearest real-time position, recording the positioning information of inertial navigation, and updating and calculating the estimated position of the vehicle according to the nearest real-time position and the positioning information of the inertial navigation;
and when the vehicle is detected to be flameout from the running state, updating and calculating the vehicle stop position according to the latest real-time position and the positioning information of the inertial navigation.
When the vehicle starts to enter the ground library, the position signal and the network signal start to be weakened, the inertial navigation device starts to be started when the position threshold value is met, and during the running period in the subsequent ground library, the latest real-time position (the last GPS position information) and the positioning information of the inertial navigation device are combined, and the vehicle position is continuously calculated and updated until the vehicle stop position is updated.
Further, after the step of updating and calculating the vehicle stop position according to the latest real-time position and the positioning information of the inertial navigation, the method further comprises the following steps:
recording the vehicle stop position;
a stop position network state is detected at the vehicle stop position, and the vehicle stop position and the stop position network state are associated and recorded as historical position information.
When the vehicle is stationary, the final position information (vehicle stop position) calculated according to the real-time position of the vehicle and the inertial navigation is obtained, the network state of the position is combined, the vehicle stop position and the stop position network state are associated and recorded as historical position information, and data are accumulated for the subsequent inertial navigation.
Optionally, after the step of associating and recording the vehicle stop position and stop position network status as historical position information, the method further comprises:
and accumulating and recording the times of the historical position information, and setting the position represented by the historical position information as the preset position when reaching a time threshold value.
Considering the real-time position of the vehicle and the accuracy of inertial navigation, when the recorded times meet a time threshold value or meet certain conditions (the position of the vehicle is in a certain range, and the parking times in the current range meet a certain number of times), marking the current position as the parking position of the vehicle, recording the parking position as historical position information, updating the preset position, and setting an error allowable range. With the subsequent continuous entering and position updating of the vehicle, the vehicle parking position is continuously updated, the more the data is, the more accurate the calculation of the vehicle parking position is, and finally, the historical position information of the parking space without the network and the position signal coverage can be obtained.
When the real-time position of the vehicle is within the error range of the preset position, the processor switches the mode of the vehicle-mounted TBOX to a sleep mode to turn off the modem to stop the network searching and network parking operation of the modem.

Said computer device 5 further comprises an onboard TBOX energy consumption reduction program stored on said memory 51 and operable on said processor 52;

step 1, detecting the real-time position of a vehicle;
and 2, when the real-time position of the vehicle is within the error range of the preset position, the processor switches the mode of the vehicle-mounted TBOX to a sleep mode so as to close the modem to stop the network searching and network parking operation of the modem.
When the vehicle reaches the error range of the preset position, the vehicle-mounted TBOX enters the sleep mode, and the modem is turned off, so that the frequent network searching, registering and switching operations under the condition of poor network state or no network at the preset position of the modem are prevented, the operations with higher power consumption are stopped, the vehicle-mounted TBOX enters the sleep mode, and the overall power consumption of the vehicle-mounted TBOX is reduced.
