The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, so that the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, the type, quantity and proportion of the components in actual implementation can be changed freely, and the layout of the components can be more complicated.
The listening method, the system, the medium and the device of the vehicle-mounted radio are used for playing a broadcasting station when a vehicle drives away from a tunnel, so that the use comfort of a user is enhanced, and the situation that the broadcasting station cannot be searched is prevented.
As shown in fig. 1a, in an embodiment of the listening method of a car radio of the present invention, it is determined whether a distance between a vehicle and a tunnel entrance is less than or equal to a first preset distance, which is a distance between the vehicle 1 and a tunnel entrance 21 of a tunnel 2, based on the position information and the driving information of the vehicle.
As shown in fig. 1b, in an embodiment of the listening method of the car radio, it is determined whether the vehicle is less than or equal to a second preset distance from the tunnel exit based on the position information and the driving information of the vehicle, where the second preset distance is the distance between the vehicle 1 and the tunnel exit 22 of the tunnel 2 and the vehicle 1 is in the tunnel 2.
As shown in fig. 1c, in an embodiment, the listening method of the car radio of the present invention is applied to a process of a vehicle running in a tunnel environment, and includes the following steps:
and step S11, judging whether the distance between the vehicle and the tunnel entrance is less than or equal to a first preset distance or not based on the position information and the running information of the vehicle.
Specifically, the vehicle-mounted radio is a vehicle-mounted RDS radio. RDS is short for radio data system. Usually, a broadcast station wants to increase its coverage, it may transmit a plurality of frequency points, for example, a certain station has two frequency points of 87.8MHz and 95.8MHz, when the vehicle is driven to listen to 87.8MHz, and goes to a certain place, the signal becomes worse, at this time, if other frequency points of the current station can be automatically searched, and when a frequency point with better and more stable signal than the original one is found, for example, 95.8MHz, the radio will automatically jump to this frequency point to listen to the previous station. And the radio with the function of automatically jumping to a better and more stable frequency point than the original frequency point for listening to the previous radio station is the vehicle-mounted RDS radio. However, if the RDS radio on board enters the tunnel, other frequency points of the head station cannot be searched because there is no car radio signal or the car radio signal is weak. And after the tunnel comes out, the user cannot jump to a frequency point which is better and more stable than the original frequency point in time to listen to the front radio station, so that the user cannot listen to the broadcasting radio station within a certain time, and the user experience comfort is reduced.
Specifically, determining whether the vehicle is less than or equal to a first preset distance from the tunnel entrance based on the position information and the travel information of the vehicle includes: the method comprises the steps of obtaining position information of a vehicle based on a vehicle-mounted GPS, obtaining driving information of the vehicle based on a vehicle-mounted navigation system, wherein the driving information comprises but is not limited to front road condition information about the vehicle to run, and obtaining whether a tunnel exists in the front of the vehicle about to run and the distance from a tunnel entrance based on the front road condition information about the vehicle to run and the position information. The first preset distance can be determined according to the time for acquiring all frequency point information of the broadcasting station of the vehicle-mounted radio sent by the cloud server and the current running speed of the vehicle, and all frequency point information of the broadcasting station of the vehicle-mounted radio sent by the cloud server can be acquired before the vehicle enters the tunnel. Whether the distance between the vehicle and the tunnel entrance is smaller than or equal to a first preset distance is judged based on the position information and the driving information of the vehicle, namely the vehicle does not enter the tunnel.
And step S12, when the distance is smaller than or equal to the first preset distance, acquiring all frequency point information of the broadcasting station of the vehicle-mounted radio sent by the cloud server.
Specifically, when the distance is less than or equal to a first preset distance, acquiring all frequency point information of a broadcast station of the car radio sent by the cloud server includes: sending the broadcasting station, the position information and the driving information to a cloud server so that the cloud server can acquire all frequency point information of the broadcasting station based on the position information and the driving information; and receiving all frequency point information of the broadcasting station sent by the cloud server. Specifically, a request for acquiring information of all frequency points of a broadcasting station of the vehicle-mounted radio is sent to the cloud server. The request includes the broadcast station, the location information, and the travel information. The broadcast station refers to a station currently being played by the vehicle-mounted radio, and the information of all frequency points of the broadcast station refers to all frequency points which can be listened to by the broadcast station. For example: the current listening is the shanghai traffic broadcasting station, and the information of all frequency points of the shanghai traffic broadcasting station refers to all frequency points which can listen to the shanghai traffic broadcasting station.
Specifically, the all frequency point information refers to all frequency point information within a preset area range, for example, the tunnel is a tunnel crossing the cixi city and the linyao city, and then the all frequency point information refers to all frequency point information within the range of the cixi city and the linyao city, which can play the broadcasting station.
Specifically, the method further comprises the following steps: and judging whether the signal of the vehicle-mounted radio in the tunnel is lower than a first preset value or not, and if so, acquiring all frequency point information of the broadcasting station of the vehicle-mounted radio sent by the cloud server. Specifically, the listening of the car radio under the condition of the car radio signal lower than the first preset value can generate large noise, intermittent and the like. The first preset value may be set based on the listening needs of the user. On the contrary, if the vehicle-mounted radio signal is higher than the first preset value when the vehicle is in the tunnel, the user can not be influenced to continuously listen to the broadcasting station through the tunnel, and all frequency point information of the broadcasting station of the vehicle-mounted radio sent by the cloud server does not need to be acquired. That is, the subsequent steps S12, S13, and S14 are not required.
And step S13, judging whether the distance between the vehicle and the tunnel exit is less than or equal to a second preset distance or not based on the position information and the driving information of the vehicle.
Specifically, judging whether the vehicle is less than or equal to a second preset distance from the tunnel exit based on the position information and the traveling information of the vehicle includes: the method comprises the steps of obtaining position information of a vehicle based on a vehicle-mounted GPS, obtaining driving information of the vehicle based on a vehicle-mounted navigation system, wherein the driving information comprises but is not limited to the information of the road condition in front of the vehicle about to run, and obtaining whether the front of the vehicle about to run is a tunnel outlet and the distance from the tunnel outlet based on the information of the road condition in front of the vehicle about to run and the position information. The second preset distance can be determined according to the time for selecting a frequency point to play the broadcasting station based on all frequency point information of the broadcasting station and the current running speed of the vehicle, so that the fact that a frequency point is selected to play the broadcasting station based on all frequency point information of the broadcasting station can be guaranteed when the vehicle is about to drive away from the tunnel exit or just drives away from the tunnel exit. And judging whether the distance between the vehicle and the tunnel exit is less than or equal to a second preset distance or not based on the position information and the running information of the vehicle, wherein the fact that the vehicle runs in the tunnel and does not leave the tunnel is meant.
And step S14, when the distance is smaller than or equal to a second preset distance, selecting a frequency point from all frequency point information of the broadcasting stations based on the current vehicle position information to play the broadcasting stations.
Specifically, when the frequency point information is less than or equal to a second preset distance, selecting a frequency point to play the broadcast station based on all the frequency point information of the broadcast station includes: and acquiring the position information of the vehicle, and selecting a frequency point from all frequency point information of the broadcasting stations based on the position information to play the broadcasting stations. Specifically, all the frequency point information of the broadcasting station includes frequency point information that each place can listen to the broadcasting station, and the frequency point information that a city corresponding to the position information can listen to the broadcasting station is selected based on the position information, and the frequency point information corresponding to the city is selected and the broadcasting station is played based on the frequency point corresponding to the frequency point information.
