Embodiment 1

[0037] An embodiment of the present invention provides a signal search method for a vehicle-mounted terminal, such as figure 1 shown, including the following steps:

[0038] S11. Preset a first search time and a second search time, and search for network signals according to a first preset time interval at the first search time. Here, the first search time and the second search time are search periods of two different stages, so the first search time and the second search time are two different time stages, for example: the first search time is 1 hour, The second search time is 2 hours. Such as figure 2 As shown, after the vehicle-mounted terminal enters the sleep state, it searches for network signals through the first search time and the second search time. Usually, the second search time will be longer than the duration of the first search time. Of course, the vehicle-mounted terminal does not enter Hibernate state can also be followed by figure 2 In this way, the sea...

Embodiment 2

[0049] An embodiment of the present invention provides a signal search device for a vehicle-mounted terminal, such as Figure 4 shown, including:

[0050] The preset search module 41 is used to preset the first search time and the second search time, and search the network signal according to the first preset time interval at the first search time;

[0051] The first search module 42 is used to search the network signal according to the second preset time interval if no network signal is found after searching the network signal for the preset number of times according to the first preset time interval, wherein the second preset time interval greater than the first predetermined time interval;

[0052] The second search module 43 is configured to search for the network signal according to the third preset time interval at the second search time if the network signal is not found after searching the network signal for a preset number of times according to the first preset time ...

Embodiment 3

[0064] An embodiment of the present invention provides a storage medium on which computer instructions are stored, and the steps of the method in Embodiment 1 are implemented when the instructions are executed by a processor. The storage medium also stores the first search time, the second search time, the first preset time interval, the second preset time interval, and the time to search for network signals at each interval between the first search time and the second search time Wait.

[0065] Wherein, the storage medium may be a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM), a random access memory (Random Access Memory, RAM), a flash memory (Flash Memory), a hard disk (Hard DiskDrive, Abbreviation: HDD) or solid state disk (Solid-State Drive, SSD), etc.; the storage medium may also include a combination of the above types of storage.

[0066] Those skilled in the art can understand that all or part of the processes in the methods of the above-m...

Abstract

The invention discloses a signal searching method and device for vehicle-mounted terminal, storage medium and vehicle-mounted terminal, and the method comprises the steps: searching a network signal at a first searching time according to a first preset time interval and not searching the network signal, searching the network signal at a second preset time interval and not searching the network signal at a second searching time according to a third preset time interval; And the third preset time interval is greater than ten times of the sum of the first preset time interval and the second preset time interval. According to the invention, the network signal is searched in the first search time and the second search time at intervals; and the preset time interval of the second search time isfar greater than the preset time interval of the first search time, so that the search efficiency can be remarkably ensured in the whole search process, and meanwhile, when the vehicle-mounted terminal enters the dormant state, the dormant current of the vehicle-mounted terminal is remarkably reduced, and the risk of whole vehicle feeding of the vehicle-mounted terminal is avoided.

Description

technical field [0001] The present invention relates to the technical field of vehicle-mounted terminals, in particular to a signal search method, device, storage medium and vehicle-mounted terminal for the vehicle-mounted terminal. Background technique [0002] The vehicle-mounted terminal is the front-end device of the vehicle monitoring and management system. It can be referred to as T-BOX. It can be used to assist the driver in collecting vehicle data during driving, for audio-visual entertainment, and to display vehicle information. The vehicle-mounted T-BOX can be connected through the wireless network. Establish remote communication with the background system / mobile APP to realize the vehicle information display and control of the mobile APP. Therefore, only when the vehicle-mounted terminal searches for a wireless network signal can remote communication be realized. [0003] At present, the signal search method of the traditional vehicle-mounted terminal generally s...
