All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes embodiments of the present invention in detail with reference to the accompanying drawings.
First embodiment
Fig. 1 is a schematic flowchart of a vehicle-mounted terminal control method according to a first embodiment of the present invention; fig. 2 is an application scenario diagram of network module sleep control of a vehicle-mounted terminal control method according to a first embodiment of the present invention; fig. 3 is an application scenario diagram of low power consumption operation control of a vehicle-mounted terminal control method according to a first embodiment of the present invention. For clearly describing the vehicle-mounted terminal control method provided by the first embodiment of the present invention, please refer to fig. 1, fig. 2 and fig. 3.
In the vehicle-mounted terminal control method provided by the invention, the vehicle-mounted terminal can be preferably provided with a high-pass SOC. The high-pass SOC platform is more and more used in the vehicle networking system, and is used as a main platform part of a vehicle intelligent system, and the 4G and 5G internet surfing functions of the high-pass SOC baseband Modem replace a traditional 4G module of an independent Tbox. The high-pass platform realizes the combination of internet modem and AP processing (Android intelligent system), so that when the vehicle is not used, the system automatically sleeps to save power consumption, and can receive network data to wake up remote control. Similarly, the method can be used for other types of vehicle-mounted terminals, and mainly aims to enable the vehicle-mounted terminal in the vehicle-mounted terminal control method provided by the invention to independently execute operation control on the communication module for dormancy without influencing the normal work of other modules. It can be understood that when the vehicle is in the area without signal, the signals of the networks 4G and 5G are weak and even no signal, similar to a mobile phone, and the mobile phone cannot receive the telephone or the short message. Because of no support of devices such as amplifiers or base stations, vehicles with the vehicle-to-vehicle networking system can continuously try to register on the nearest base station, so that a large amount of ineffective energy is consumed, the electricity consumption of the vehicles can be exhausted in about 3 days, and the vehicle feeding cannot be started, and other serious consequences can be caused. Therefore, a method for controlling a vehicle-mounted terminal according to a first embodiment of the present invention is provided, which specifically includes the following steps:
step S1: and acquiring the signal strength of the network signal in response to the vehicle being in the low power consumption state.
In one embodiment, in step S1: the method comprises the steps of responding to the condition that the vehicle is in a low power consumption state, obtaining vehicle state information before obtaining the signal intensity of a network signal, and judging that the vehicle is in the low power consumption state when the vehicle state accords with a flameout state and exceeds a preset time threshold value.
In one embodiment, in step S1: the method comprises the steps of responding to the condition that a vehicle is in a low power consumption state, obtaining position information of the vehicle before obtaining the signal strength of a network signal, and judging that the vehicle is in the low power consumption state when the position information of the vehicle corresponds to a weak signal area or an area without the network.
In one implementation, the vehicle-mounted terminal control method provided by the first embodiment of the invention responds in a low power consumption state of the vehicle. The method comprises the following steps that firstly, whether the vehicle is in a flameout state or not is judged according to the vehicle state; and secondly, judging whether the vehicle is in a non-network or weak network environment according to the vehicle position information. Specifically, for the vehicle flameout state, the vehicle may be determined to enter the low power consumption state after the vehicle owner flameout and leaves the vehicle for more than a preset time, preferably for 3 minutes, and a response is correspondingly executed. For the vehicle position, it may be determined whether the vehicle is in a weak signal or no signal area such as an underground parking lot, a mountain area, an overhead area, or the like, specifically, a time threshold exceeding a certain time may be added, for example, preferably, 3 minutes may be added, that is, if the time for keeping the same type of position exceeds 3 minutes, it is determined that the vehicle enters a low power consumption state, and a response is correspondingly executed.
Step S2: and matching corresponding vehicle-mounted terminal control information according to the signal intensity, wherein the vehicle-mounted terminal control information comprises low-power-consumption work control information or network module dormancy control information.
In one embodiment, in step S2: the step of matching the corresponding vehicle-mounted terminal control information according to the signal intensity comprises the following steps: judging whether the network signal accords with a non-network service state or a weak signal state according to the signal strength: responding to the network signal conforming to the non-network service state, generating network module dormancy control information to enable the vehicle-mounted terminal to stop network scanning registration and execute timing awakening operation, wherein the timing awakening operation comprises the following steps: and setting a timing awakening alarm clock, and controlling to awaken a network module in the vehicle-mounted terminal when the time condition of the timing awakening alarm clock is met so that the vehicle-mounted terminal can perform network scanning registration. The network scanning registration is an execution step of implementing network connection between a network module in the vehicle-mounted terminal and the base station and determining whether the vehicle-mounted terminal is connected with a corresponding network, and in short, determining whether network communication is achieved.
In an implementation manner, reference may be made to fig. 2 for a specific application scenario of network module sleep control of the vehicle-mounted terminal control method according to the first embodiment of the present invention. Specifically, when the signal strength of the network signal acquired by the vehicle-mounted terminal is in a no-signal state, the vehicle-mounted terminal does not register with the base station, and immediately enters an idle (standby) state of a modem (modem), that is, a network module sleep state, and stops scanning the network again, thereby reducing unnecessary energy consumption. And when the corresponding time condition is met, waking up the network module of the vehicle-mounted terminal once so as to enable the vehicle-mounted terminal to perform network scanning registration. Specifically, the vehicle-mounted terminal after waking up also acquires the signal strength of the network signal again and determines whether to need to go to sleep again or enter a low power consumption state or wake up normally. The preset time may be preferably 3 hours, that is, waking up every 3 hours, determining whether the network signal meets the registration condition, if not, sleeping for three hours again, and repeating the above steps until the network is successfully woken up.
In one embodiment, in step S2: the step of matching the corresponding vehicle-mounted terminal control information according to the signal intensity comprises the following steps: judging whether the network signal accords with the non-network service state or the weak signal state according to the signal strength: and generating low-power-consumption work control information in response to the fact that the network signal accords with the weak signal state, so that the vehicle-mounted terminal can acquire the network signal at regular time.
In one embodiment, in the process of regularly acquiring the network signal by the vehicle-mounted terminal, when the network signal is not acquired for more than a preset number of times, the network module is controlled to enter a sleep state, so that the vehicle-mounted terminal stops scanning and registering and controls the network module of the vehicle-mounted terminal to enter the sleep state, the vehicle-mounted terminal stops scanning and registering and executes a timed wake-up operation on the network module of the vehicle-mounted terminal, and the timed wake-up operation includes: and setting a timing awakening alarm clock, and controlling and awakening a network module in the vehicle-mounted terminal when the time condition of the timing awakening alarm clock is met so as to enable the vehicle-mounted terminal to carry out network scanning registration.
In one embodiment, in step S2: the step of matching the corresponding vehicle-mounted terminal control information according to the signal intensity comprises the following steps: judging whether the network signal accords with the non-network service state or the weak signal state according to the signal strength: and generating low-power-consumption work control information in response to the fact that the network signal accords with the weak signal state, so that the vehicle-mounted terminal can acquire the network signal at regular time.
In an implementation manner, for an application scenario of low power consumption operation control of the in-vehicle terminal control method provided in the first embodiment of the present invention, reference may be made to fig. 3. Specifically, for the case that the Signal Strength of the acquired network Signal is consistent with the weak Signal, the preferable determination threshold may be whether the Signal Strength is lower than RSSI-100 (Received Signal Strength of RSSI: received Signal Strength Indicator, used for determining the link quality), and if so, the Signal Strength is consistent with the weak Signal state, and the low-power-consumption operation control information is controlled and generated. Further, the specific implementation for the timing acquisition of the network signal may be. When the network signal is lower than a weak signal threshold RSSI-100, controlling the vehicle-mounted terminal to adopt the network signal strength according to a preset frequency, preferably collecting a signal value every 5 seconds for 6 times in total, and if 4 times are lower than the weak signal threshold, controlling the vehicle-mounted terminal to enter an idle state of the modem, namely controlling the network module to be in a sleep state; otherwise, the network is normally registered. The detailed description of the method for implementing the network module sleep control is already provided in the foregoing, and reference may be made to the explanations in the foregoing specifically, which is not described herein again.
And step S3: and controlling the vehicle-mounted terminal according to the vehicle-mounted terminal control information.
In one embodiment, in step S3: in controlling the vehicle-mounted terminal according to the vehicle-mounted terminal control information, the method further comprises the following steps: and acquiring vehicle state information, and controlling the vehicle-mounted terminal to perform network scanning registration when the vehicle state accords with the starting state until the registration is successful.
In an embodiment, after the network module of the vehicle-mounted terminal enters a low power consumption state or a dormant state, the vehicle-mounted terminal exits at a proper time, wherein the low power consumption state is subjected to low-frequency network scanning judgment, the dormant state is subjected to network scanning judgment after timed awakening, and the vehicle as a whole can be judged according to the vehicle state, namely when a vehicle owner ignites to start the vehicle, the network module of the vehicle-mounted terminal is immediately awakened to try network scanning registration until network connection is successful. Furthermore, according to the technical scheme, for the approach of entering the low power consumption mode through the vehicle position information, the vehicle-mounted terminal can be awakened without the method, or a time judgment is added, for example, the network module of the vehicle-mounted terminal can be awakened every 10 minutes when the vehicle position information enters the low power consumption mode.
In one embodiment, in step S3: in controlling the vehicle-mounted terminal according to the vehicle-mounted terminal control information, the method further comprises the following steps: when the vehicle-mounted terminal control information comprises low-power-consumption work control information, acquiring electric quantity information; and when the electric quantity information is lower than a preset threshold value, controlling a network module in the vehicle-mounted terminal to enter a dormancy state.
In one embodiment, the battery level of the vehicle needs to be monitored in real time for the network module in the low power consumption operation control state. It can be understood that the vehicle-mounted terminal control method provided by the invention is used for saving electric quantity and preventing ineffective energy consumption. Although the low power consumption mode is energy-saving, actually, the network module is controlled to work to a certain extent, that is, energy consumption to a certain extent is caused, and therefore, when the electric quantity is lower than a preset threshold value, the network module is controlled to enter a sleep state so as to execute a response corresponding to the sleep control information of the network module.
The vehicle-mounted terminal control method provided by the first embodiment of the invention comprises the following steps: step S1: responding to the low power consumption state of the vehicle, and acquiring the signal intensity of the network signal; step S2: matching corresponding vehicle-mounted terminal control information according to the signal intensity, wherein the vehicle-mounted terminal control information comprises low-power-consumption work control information or network module dormancy control information; and step S3: and controlling the vehicle-mounted terminal according to the vehicle-mounted terminal control information. Therefore, the invention can actively control the vehicle-mounted terminal to execute the corresponding response to enter the low power consumption or sleep mode under the network-free or weak network state, reduce unnecessary energy consumption, avoid the problem that the whole vehicle feed cannot be started due to long-time ineffective power consumption, and realize the technical effects of saving energy and improving the working effectiveness of the vehicle-mounted terminal. Furthermore, the control method for the vehicle according to an embodiment of the present invention can match different control modes according to signal strengths of different network signals to perform targeted adjustment, so that the ready state of the vehicle-mounted terminal can be ensured to respond at any time while saving energy. Furthermore, in the low power consumption mode state, the battery electric quantity is detected in real time, the vehicle-mounted terminal is switched from low power consumption to dormancy, effective use of the electric quantity is guaranteed, user operation is reduced, user convenience is improved, and user experience is improved.
Second embodiment
Fig. 4 is a flowchart illustrating a vehicle-mounted terminal control method according to a second embodiment of the present invention. For clearly describing the vehicle-mounted terminal control method provided by the second embodiment of the present invention, please refer to fig. 4.
A control method for a vehicle-mounted terminal according to a second embodiment of the present invention includes the steps of:
step S21: and acquiring the signal strength of the network signal in response to the vehicle being in the low power consumption state.
In one embodiment, two embodiments may be preferable for the determination as to whether the vehicle is in the low power consumption state. Firstly, according to whether the vehicle state corresponds to a flameout state and whether the flameout state is kept to exceed a preset time threshold, for example, three minutes, specifically, after a user flameout for three minutes, the vehicle is determined to be in a low power consumption state, and then the subsequent steps are correspondingly executed; secondly, according to the position information of the vehicle, it can be understood that when the vehicle is in an underground parking lot, or is located on a congested highway, a mountain wilderness area, or the like, the positions are all the conditions that the network signal state is poor, and the network module of the vehicle-mounted terminal does not need or cannot perform network interconnection, so that the vehicle is judged to be in a low power consumption state in the same way.
Step S22: judging whether a network signal exists:
if not, executing step S23: controlling the vehicle-mounted terminal according to the network module dormancy control information;
in one embodiment, the network module in the vehicle-mounted terminal can be used as an execution subject for acquiring, analyzing and judging whether the network signal is acquired and whether the network signal is present or not and the strength of the signal strength.
In an embodiment, when the network signal is not acquired at all, the network module does not need to work at all, so the vehicle-mounted terminal is controlled according to the generated network module sleep control information to close the function of the network module, and the network scanning is stopped to enter the sleep state. In addition, furthermore, after the vehicle-mounted terminal enters the network module dormant state, a timing wake-up alarm clock is started, timing is carried out according to a preset time condition, and when the corresponding time condition is met, the network module of the vehicle-mounted terminal is wakened up once, so that the vehicle-mounted terminal carries out network scanning registration. The time condition is that the network module is allowed to scan the network at an extremely low frequency, specifically, the time may be once every three hours, and the network module is awakened every three hours to determine whether the network signal strength is to perform network connection again.
If yes, go to step S24: judging whether the signal belongs to a weak signal state:
if yes, go to step S25: controlling the vehicle-mounted terminal according to the low-power-consumption work control information;
in an embodiment, for the case that the signal strength of the acquired network signal is consistent with a weak signal, the preferable determination threshold may be whether the signal strength is lower than RSSI-100, and if so, the signal strength is consistent with a weak signal state, and the low-power-consumption operation control information is controlled to be generated. Further, the specific implementation for the timing acquisition of the network signal may be. When the network signal is lower than the weak signal threshold RSSI-100, the vehicle-mounted terminal is controlled to adopt the network signal strength according to the preset frequency, preferably, the signal value is collected once every 5 seconds, the signal value is collected 6 times in total, and if the signal value is lower than the weak signal threshold 4 times, the network module is controlled to be in sleep. That is, for the low power consumption control in the weak signal state, the network scanning frequency of the network module is reduced, but the network module is not necessarily completely shut down, and when the weak signal acquired according to the preset frequency corresponds to the preset condition, the network module is also controlled to sleep.
If not, executing step S26: and (5) surfing the Internet normally.
A control method for a vehicle-mounted terminal according to a second embodiment of the present invention includes the steps of: step S21: responding to the condition that the vehicle is in a low power consumption state, and acquiring the signal strength of a network signal; step S22: judging whether a network signal exists: if not, executing step S23: controlling the vehicle-mounted terminal according to the network module dormancy control information; if yes, go to step S24: judging whether the signal belongs to a weak signal state: if yes, go to step S25: controlling the vehicle-mounted terminal according to the low-power-consumption work control information; if not, executing step S26: and (5) surfing the Internet normally. For the vehicle-mounted terminal control method provided in the second embodiment of the present invention, actually, one specific implementation manner of the vehicle-mounted terminal method provided in the first embodiment of the present invention is implemented, so that the beneficial effects achieved are consistent, and specifically, reference may be made to the foregoing, and details are not repeated herein.
