Description

Technical Field

[0001] The present invention relates to the field of vehicle communication technology, and in particular to a TBOX network search method, device and computer-readable storage medium. Background Art

[0002] In the existing technology, TBOX (Telematics Box, remote communication terminal) is an important module of the vehicle, which is used to provide networking functions for the vehicle computer. Therefore, it is very important to control the power consumption of TBOX.

[0003] At present, the abnormal power consumption of TBOX is mainly caused by invalid network search under weak signal or no signal, especially in the scenario of frequent network loss and network search under no signal or relatively weak signal. At this time, the network search action under no signal will involve full-band and full-standard network search. Due to the large number of standards and frequency bands, and the relatively short network search cycle, the power consumption is greatly increased compared with the usual. If the network search cycle is simply extended to deal with weak signal or no signal, for example, the network search cycle is extended to once every 10 minutes or 30 minutes, it is impossible to effectively control the power consumption problem caused by TBOX network search.

[0004] Therefore, how to effectively reduce the frequent network searches of TBOX under relatively weak signals or no signals and save the power consumption of TBOX has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to overcome the deficiencies in the prior art, the present invention aims to provide a TBOX network search method, device and computer-readable storage medium to solve the power consumption problem caused by the frequent network searches of the current TBOX under relatively weak signals or no signals.

[0006] The present invention proposes a TBOX network search method, which comprises: When it is detected that the vehicle network connection is disconnected, obtaining the current location of the vehicle and the duration of the network search; Detecting whether the current location satisfies a preset location condition and / or whether the network search duration satisfies a preset time condition; If the current location satisfies the location condition and / or the network search duration satisfies the time condition, the network search is stopped.

[0007] Optionally, the method further comprises: Presetting a distance threshold corresponding to the current location, and determining a historical location associated with the current location; A relative distance between the current location and the historical location that is less than the distance threshold is determined as satisfying the location condition.

[0008] Optionally, the method further comprises: Presetting a time threshold corresponding to the current position; The network search duration being greater than the duration threshold is determined as satisfying the time condition.

[0009] Optionally, the obtaining of the current position of the vehicle and the duration of the continuous network search further includes: determining a location database corresponding to the current location; A historical location associated with the current location is detected in the location database.

[0010] Optionally, the detecting whether the current location satisfies a preset location condition and / or whether the network search duration satisfies a preset time condition specifically includes: When the historical location is detected in the location database, detecting whether the current location satisfies the location condition, and whether the network search duration satisfies the time condition; When the historical location is not detected in the location database, it is detected whether the network search duration meets the time condition.

[0011] Optionally, when the current location satisfies the location condition and / or the network search duration satisfies the time condition, stopping the network search specifically includes: When the historical location is detected in the location database, if the current location satisfies the location condition and the network search duration satisfies the time condition, then the network search is stopped; If the current location satisfies the location condition, and the network search duration does not satisfy the time condition, the network search continues until the network search duration satisfies the time condition, and the network search is stopped.

[0012] Optionally, when the current location satisfies the location condition and / or the network search duration satisfies the time condition, stopping the network search further includes: If the current location does not satisfy the location condition, and the network search duration satisfies the time condition, then updating the duration threshold in the time condition according to the relative distance between the current location and the historical location in the location condition; The network search is performed again according to the updated time condition, and the network search is stopped until the new network search duration meets the updated time condition, or until the current location meets the location condition.

[0013] Optionally, when the current location satisfies the location condition and / or the network search duration satisfies the time condition, stopping the network search specifically includes: When the historical location is not detected in the location database, if the network search duration meets the time condition, stopping the network search; If the network search duration does not meet the time condition, the operation of detecting the historical location associated with the current location in the location database is continuously performed during the network search process until the network search duration meets the time condition and the network search is stopped. Alternatively, during the network search process, if the historical location is detected in the location database, and the current location meets the location condition and the network search duration meets the time condition, the network search is stopped.

[0014] The present invention also proposes a TBOX network search device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program implements the steps of any of the above TBOX network search methods when executed by the processor.

[0015] The present invention further proposes a computer-readable storage medium on which a TBOX network search program is stored. When the TBOX network search program is executed by a processor, the steps of the TBOX network search method as described in any one of the above items are implemented.

[0016] The TBOX network search method, device and computer-readable storage medium of the present invention are implemented by obtaining the current position of the vehicle and the duration of the network search when the vehicle network connection is detected to be disconnected; detecting whether the current position meets the preset position condition and / or whether the network search duration meets the preset time condition; and stopping the network search when the current position meets the position condition and / or the network search duration meets the time condition. An adaptive TBOX network search solution is implemented, which effectively solves the power consumption problem caused by frequent network searches of the vehicle TBOX, improves the utilization rate of the vehicle's electric energy, and enhances the vehicle experience.

DETAILED DESCRIPTION

[0018] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0019] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0020] Figure 1 This embodiment proposes a TBOX network search method, which includes: S1. When it is detected that the vehicle network connection is disconnected, the current position of the vehicle and the duration of the network search are obtained; S2, detecting whether the current location satisfies a preset location condition and / or whether the network search duration satisfies a preset time condition; S3: When the current location satisfies the location condition and / or the network search duration satisfies the time condition, stop the network search.

[0021] In this embodiment, when the vehicle enters a fixed area, such as a basement, a shopping mall parking lot, or other relatively weak signal or no signal area, the TBOX may be disconnected from the network. At this time, the historical location information and the saved duration of no network and relatively weak signal are read; the subsequent judgment is performed by comparing the historical location information with the current location information. If the distance difference between the two is within a predetermined threshold (for example, 3 meters, 5 meters, etc.), and the historically maintained no network or weak signal time exceeds a preset time length (for example, 1 hour, two hours, etc.), that is, the history records that the device has not registered on the network for one hour. At this time, it can be determined that this area has a weak signal or no signal; based on this, it can be determined that the terminal has searched the network for all frequency bands of 5G / 4G / 3G standards many times in the previous hour, thereby eliminating the situation where there is a signal misjudgment in the area, that is, it is determined that this is a weak signal area or a no signal area. At this time, the terminal turns off the network search function and waits for the next time the vehicle uses the area to exceed the predetermined threshold to search the network immediately. If the location information is not in the historical data, the terminal will search for the network. Otherwise, if the network search exceeds 1 hour and still cannot register any network, the location information and the network-free time will be recorded in the historical data, and the terminal will stop searching for the network. In this way, the purpose of TBOX searching for the network and saving power is achieved. When the terminal uses the area exceeding the predetermined threshold, the network search will be performed again, so that TBOX can also quickly register the network outside the above area.

[0022] In this embodiment, one situation is that when the vehicle enters a certain area to park and the TBOX loses the network, the historically stored location information and the duration of network loss are read. If the distance between the current location information and the historical location information is less than a preset threshold, and the historical network loss time exceeds the preset duration, the network search is stopped and the TBOX enters a sleep state.

[0023] In this embodiment, another situation is that if the distance difference between the historical data read by the vehicle at this location and the current location is less than the preset threshold, and the network-free time is less than the preset duration, it is determined that there is a signal in this place, and the current network-free may be caused by other reasons, then the terminal searches the network according to the normal network search cycle.

[0024] In this embodiment, there is another situation. If the distance difference between the historical data read by the vehicle at this location and the current location is greater than a preset threshold or there is no historical location information, it is determined that the vehicle has arrived at the area for the first time, and the terminal searches the network according to the normal network search cycle. If it cannot register on any network for more than the preset time, it is determined that the area is a weak signal area or a no signal area, and the terminal stops searching the network, otherwise it continues to search the network.

[0025] It can be seen that in this embodiment, when entering a fixed area to park and the TBOX has no network, the historical location information is read and compared with the current location information to see if the difference is within a predetermined threshold. If so, the network search is stopped and the terminal enters a sleep state. When the location area is larger than the preset threshold, the terminal starts to search the network. If there is no historical location information or the difference between the current location information and the historical location information is larger than the preset threshold, the terminal searches the network according to a predetermined period. If no network is registered for more than the preset time, the terminal stops searching the network and enters a sleep state.

[0026] The beneficial effect of this embodiment is that, when the vehicle network connection is detected to be disconnected, the current location of the vehicle and the duration of the network search are obtained; whether the current location meets the preset location condition and / or whether the network search duration meets the preset time condition is detected; when the current location meets the location condition and / or the network search duration meets the time condition, the network search is stopped. An adaptive TBOX network search solution is implemented, which effectively solves the power consumption problem caused by frequent network searches of the vehicle TBOX, improves the utilization rate of the vehicle's electric energy, and enhances the vehicle experience.

[0027] Figure 2 FIG. 2 is a second flow chart of the TBOX network search method of the present invention. Based on the above embodiment, the method further includes: S01, presetting a distance threshold corresponding to the current position, and determining a historical position associated with the current position; S02: If the relative distance between the current location and the historical location is less than the distance threshold, it is determined that the location condition is satisfied.

[0028] In this embodiment, the distance threshold is determined according to the current position. For example, when in an underground garage in a residential area, a smaller distance threshold is determined, and when under a bridge or in a tunnel, a larger distance threshold is determined.

[0029] In this embodiment, the current position is associated with the historical position. The associated relationship may be, on the one hand, storage data of the historical relationship private to the vehicle, and on the other hand, relationship data shared by other vehicles.

[0030] Figure 3 FIG. 3 is a third flow chart of the TBOX network search method of the present invention. Based on the above embodiment, the method further includes: S03, presetting a time threshold corresponding to the current position; S04: Determine that the network search duration is greater than the duration threshold as satisfying the time condition.

[0031] In this embodiment, the duration threshold is also determined according to the current location. For example, when in an underground garage in a residential area, a longer duration threshold is determined, and when under a bridge or in a tunnel, a shorter duration threshold is determined.

[0032] In this embodiment, the duration threshold may also be determined according to the speed at the current position. For example, when the speed is faster, a shorter duration threshold is determined, and when the speed is slower, a longer duration threshold is determined.

[0033] In this embodiment, when the vehicle is traveling, the duration threshold may also be determined according to the speed at the current position, and when the vehicle is stopped, the duration threshold may be determined according to the current position.

[0034] Figure 4 This is a fourth flow chart of the TBOX network search method of the present invention. Based on the above embodiment, the step of obtaining the current position of the vehicle and the continuous network search duration further includes: S11, determining a location database corresponding to the current location; S12: Detecting a historical location associated with the current location in the location database.

[0035] In this embodiment, the above-mentioned location database can be, on the one hand, storage data private to the vehicle, and on the other hand, can also be relational data shared by other vehicles.

[0036] Figure 5This is a fifth flow chart of the TBOX network search method of the present invention. Based on the above embodiment, the step of detecting whether the current location meets the preset location condition and / or whether the network search duration meets the preset time condition specifically includes: S21, when the historical location is detected in the location database, detecting whether the current location meets the location condition, and whether the network search duration meets the time condition; S22: When the historical location is not detected in the location database, detect whether the network search duration meets the time condition.

[0037] In this embodiment, on the one hand, when the historical position is detected, two conditions are detected, namely, whether the current position meets the position condition and whether the network search duration meets the time condition; on the other hand, when the historical position is not detected, only one condition is detected, namely, whether the network search duration meets the time condition. However, the vehicle is movable, and in this case, once the historical position is detected in the position database, it is necessary to confirm again whether the network search duration meets the time condition and whether the current position meets the position condition.

[0038] Figure 6 This is the sixth flow chart of the TBOX network search method of the present invention. Based on the above embodiment, when the current location satisfies the location condition and / or the network search duration satisfies the time condition, the network search is stopped, which specifically includes: S31, when the historical location is detected in the location database, if the current location satisfies the location condition and the network search duration satisfies the time condition, then stop the network search; S32: If the current location satisfies the location condition and the network search duration does not satisfy the time condition, continue searching the network until the network search duration satisfies the time condition and stops searching the network.

[0039] In this embodiment, if the current position meets the position condition after the vehicle stops, and the network search duration does not meet the time condition, the network search continues until the network search duration meets the time condition and then stops; and if the vehicle moves, the network search starts again.

[0040] Figure 7 This is the seventh flow chart of the TBOX network search method of the present invention. Based on the above embodiment, when the current location satisfies the location condition and / or the network search duration satisfies the time condition, the network search is stopped, and further includes: S33: if the current location does not satisfy the location condition and the network search duration satisfies the time condition, updating the duration threshold in the time condition according to the relative distance between the current location and the historical location in the location condition; S34, performing network search again according to the updated time condition, until the new network search duration meets the updated time condition, or until the current location meets the location condition, then stopping the network search.

[0041] In this embodiment, after the vehicle stops, the network search is performed again according to the updated time condition until the new network search duration meets the updated time condition, or until the current position meets the position condition, then the network search is stopped; if the vehicle moves, the network search is started again.

[0042] Figure 8 This is the eighth flow chart of the TBOX network search method of the present invention. Based on the above embodiment, when the current location satisfies the location condition and / or the network search duration satisfies the time condition, the network search is stopped, which specifically includes: S35, when the historical location is not detected in the location database, if the network search duration meets the time condition, stop the network search; S36. If the network search duration does not meet the time condition, the operation of detecting the historical location associated with the current location in the location database is continuously performed during the network search process until the network search duration meets the time condition and the network search is stopped; or, during the network search process, if the historical location is detected in the location database, and the current location meets the location condition and the network search duration meets the time condition, the network search is stopped.

[0043] In this embodiment, after the vehicle stops, if the network search duration does not meet the time condition, the operation of detecting the historical location associated with the current location in the location database is continuously performed during the network search process until the network search duration meets the time condition, then the network search is stopped; or, during the network search process, if the historical location is detected in the location database, and the current location meets the location condition and the network search duration meets the time condition, then the network search is stopped. If the vehicle moves, the network search is started again.

[0044] Based on the above embodiments, the present invention also proposes a TBOX network search device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, the steps of the TBOX network search method described in any one of the above items are implemented.

[0045] It should be noted that the above-mentioned device embodiment and method embodiment belong to the same concept, and the specific implementation process is detailed in the method embodiment, and the technical features in the method embodiment are correspondingly applicable in the device embodiment, which will not be repeated here.

[0046] Based on the above embodiments, the present invention further proposes a computer-readable storage medium, on which a TBOX network search program is stored. When the TBOX network search program is executed by a processor, the steps of the TBOX network search method as described in any one of the above items are implemented.

[0047] It should be noted that the above-mentioned medium embodiment and method embodiment belong to the same concept, and the specific implementation process is detailed in the method embodiment, and the technical features in the method embodiment are correspondingly applicable in the medium embodiment, which will not be repeated here.

[0048] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal (which can be a mobile phone, a computer, a server, an air conditioner, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
