Description
Technical Field
The invention relates to the technical field of information processing, in particular to a vehicle-mounted end, an information processing system and a vehicle-mounted end radio uninterrupted playing method.
Background
The radio is the basic function of modern vehicle-mounted terminal technology. In a high-speed life rhythm, the radio not only helps to relax the driving emotion of the user, but also helps the user to acquire the latest information. According to statistics, the radio is the most frequent function of the use times of the vehicle-mounted end.
Radio is mainly of Frequency Modulation (FM) and Amplitude Modulation (AM) systems, which receive different radio stations based on the principle of short-wave communication radio stations. As one of the station broadcasts, fm broadcasts distribute program contents by way of radio transmission. Unlike amplitude modulation broadcasting, frequency modulation broadcasting transmits audio signals in a frequency modulation mode, a carrier of a frequency modulation wave changes on both sides of a carrier center frequency (center frequency before unmodulation) along with changes of an audio modulation signal, the frequency offset change frequency per second is consistent with the modulation frequency of the audio signal, and if the frequency of the audio signal is 1kHz, the frequency offset change frequency of the carrier is 1000 times per second. The magnitude of the frequency offset is dependent on the magnitude of the amplitude of the audio signal. The FM broadcasting has strong anti-interference capability, small signal distortion and high equipment utilization rate.
However, each broadcast frequency can only cover a specific area due to the limitations of the radio station transmission power, the radio wave propagation distance and the transmission antenna directivity, and the short-wave broadcast coverage of each large radio station cannot be completed by one point of frequency. Therefore, the same station needs to set up different rebroadcasting stations in different segment areas (such as different cities generally) to pass different frequencies, so as to enlarge the coverage rate of the station broadcast. For example, the Chinese radio station has FM 106.1 in Beijing, 99.0 in Shanghai, 89.3 in Guangzhou, and has specific FM in other areas. However, based on different fm settings of the same station in different segment areas, when the user arrives at a new city during driving, the vehicle-mounted terminal searches for and refreshes the station list based on the current city where the user is located. And based on the refreshed frequency of the radio station which is listened to by the user in the city local radio station list, the corresponding broadcast station is likely to change, so that the user cannot continuously listen to the same radio station channel. If the user wants to call back the originally listened radio station, the user needs to re-tune based on the refreshed local radio station list of the city.
Furthermore, due to the limitations of frequency resources of the available stations and the frequency band effects on the band broadcast caused by the effects of reflection of radio waves by different regional terrains, latitudes, climates, etc. in actual operation. In different areas, the radio signals may be weak, unstable, and easily suppressed by the same frequency in the local area. In addition to radio selection limitations, local strong stations in close proximity to the frequency can also push down remote weak station signals. Therefore, after entering different segment areas, there is no guarantee that the station list of the segment area includes the broadcasting stations listened to by the original users, and even if the original broadcasting stations are included, the stations may have problems of instability, heavy noise, and the like due to signal problems.
Therefore, the problem that the playing function of the vehicle-mounted end sound receiver is troubled always is solved by how to solve the defects that the frequency modulation change of the radio stations causes the user to experience the vehicle-mounted end customer, such as the fact that the user cannot continuously listen to the same radio station and the radio station has poor receiving effect, based on the regional difference.

Detailed Description
As described in the background section, in the prior art, when a vehicle-mounted terminal enters another city from one city, based on the frequency modulation frequency change corresponding to the current radio station listened to by a user in different cities, or the frequency band influence on the band broadcast sound caused by the influence on the radio wave reflection such as the terrain, latitude, and climate of each region, the broadcast signal reception of the current radio station is poor and interrupted, so that the user cannot continuously listen to the broadcast information of the current radio station. The invention provides a vehicle-mounted end, an information processing system and a vehicle-mounted end radio uninterrupted playing method. The method monitors the local radio station radio signal of the current radio station of the vehicle-mounted end, and receives the network broadcast information of the network radio station corresponding to the current radio station of the vehicle-mounted end through the cloud server when the local radio station radio signal has signal receiving obstacles, so that the vehicle-mounted end is kept receiving the broadcast information of the current radio station, and a user can continuously listen to the current radio station.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments disclosed below.
Referring to fig. 1, the present invention provides a vehicle-mounted terminal including: the system comprises a local radio station module 1, a radio station connection switching module 2 and a network radio station module 3. The radio station connection switching module 2 is respectively connected with the local radio station module 1 and the network radio station module 3.
The local radio station module 1 is used for receiving a local radio station radio signal of the current location of the vehicle-mounted terminal; determining a current radio station based on user selection, and receiving local radio station broadcast information of the current radio station;
the radio station connection switching module 2 is used for executing the local radio signal index test of the current radio station; if the local radio signal index of the current radio station is lower than the standard critical value, starting a network radio station module based on user selection;
the network radio station module 3 is started and then sends a network radio station acquisition request to the cloud server, wherein the network radio station acquisition request comprises a request for acquiring network radio station information corresponding to the current radio station; and after the network radio station information is acquired, acquiring the network broadcast information of the network radio station corresponding to the current radio station.
The local radio station module 1 of the vehicle-mounted end can receive a local radio station radio signal of the current location of the vehicle-mounted end, and the network radio station module 3 can receive a network end radio station signal; the radio station is connected with the switching module 2, and a user realizes the switching of the local radio station module 1 and the network radio station module 3. As shown with reference to fig. 2, the radio station connection switching module 2 specifically includes: a local station signal measuring module 21, an intensity judging module 22 and an instruction executing module 23.
The local radio station signal measuring module 21 is connected to the local radio station module 1, and configured to read a test value corresponding to the local radio signal indicator test of the current radio station;
and the strength judging module 22 is connected with the local station signal measuring module 21. After the strength judgment module 22 obtains the test value, the test value is compared with the standard critical value, and based on the comparison result, when the test value is smaller than the standard critical value, a network radio station starting prompt instruction is formed.
The instruction execution module 23 is connected to the network radio station module 3, and the instruction execution module 23 starts the network radio station module 3 based on the confirmation of the network radio station start prompt instruction by the user.
If the "chinese voice" is modulated by 99.0 in the shanghai and the "hangzhou" is modulated by 92.0 in the hangzhou, when the user travels from shanghai to hangzhou, based on the location of the "chinese voice" shanghai broadcasting station, the vehicle-mounted terminal cannot receive the "chinese voice" local wireless signal in shanghai and hangzhou well, and at this time, if the strength determination module 22 obtains that the signal-to-noise ratio of the shanghai broadcasting station measured by the local broadcasting station signal measurement module 21 with respect to the "chinese voice" is only 40 decibels (dB), it is determined that the test value is less than the standard-reaching critical value of 60dB, and then a network broadcasting station start prompt instruction is formed. And the user starts the network radio station module 3 based on the network radio station starting prompt instruction sent by the vehicle-mounted end, and receives the network broadcast information of the network radio station corresponding to the Chinese voice. It should be noted that in this embodiment, the signal-to-noise ratio is used as the test parameter of the local radio signal indicator, and in the actual design, the test parameter of the local radio signal indicator may further include multipath delay, rayleigh fading, bit error rate, and frequency offset. The standard reaching threshold value can be preset. These criteria can be established according to the usual criteria in the field and do not limit the scope of protection of the present invention.
In addition to the influence of the position relationship between the vehicle-mounted end and the relay station arranged in different areas where each radio station is located on the reception of the radio signal of the local radio station by the local radio station module 1, the terrain, latitude, climate and selection limitation of the vehicle-mounted end to the reception of the radio signal may also cause radio signal reception obstacles. Thus, even if the vehicle-mounted terminal is always in the Shanghai environment, the receiving effect of the radio signals of the local radio station of China's voice fluctuates at different positions. At this time, the strength determining module 22 may also form the network station start prompting instruction based on the test value measured by the local station signal measuring module 21, and start the network station module 3 based on the user selection.
After the network radio station module 3 starts to receive network data, corresponding network flow can be generated, and the listening cost of a user to the radio station is increased. Thus, in the present invention, the local station module 1 is still in continuous reception of local station radio signals while the network station module 3 is on. And when the test value obtained by the test of the strength judgment module 22 is greater than the standard-reaching critical value, a prompt instruction for restarting the local radio station is formed. The instruction execution module 23 may further close the network radio station module 3, start the local radio station module 1, and receive the local radio station broadcast information of the current radio station, based on the confirmation that the user has re-enabled the prompt instruction for the local radio station. For example, when based on the user's selection, the vehicle-mounted terminal is receiving the network broadcast information of the network station corresponding to "Chinese voice". When the signal-to-noise ratio of the local radio station radio signal of the "chinese sound" determined by the local radio station signal determination module 21 by the intensity determination module 22 is 80dB, which is greater than the standard critical value by 60dB, the intensity determination module 22 forms a local radio station re-enabling prompt instruction, and the user can turn off the network radio station module 3 based on the local radio station re-enabling prompt instruction, and re-use the local radio station module 1 to receive the broadcast information of the "chinese sound". Therefore, the user can continuously listen to the Chinese voice column, and the network traffic expenditure is saved.

The command recognition module 242 is connected to the voice recognition module 241, the local station module 1 and the network station module 3.
Wherein, one of the implementation modes is as follows:

the instruction recognition module 242 parses the instruction text, and if the instruction text is an instruction text corresponding to a confirmation instruction, the network radio station module 3 is started or the local radio station module 1 is restarted, so as to receive the network broadcast information or the local radio station broadcast information of the current radio station.
In addition to the above-described embodiments,

the instruction recognition module 242 analyzes the instruction text, and starts the internet radio station module 3 if the instruction text is an instruction text for starting an internet radio station; and if the instruction text is the instruction text for starting the local radio station, starting the local radio station module 1.
Through the setting of the voice control module 24, in the process of selecting the local radio station mode and the network radio station mode of the vehicle-mounted terminal by the user, the starting and switching of the two radio station modes can be directly realized through a voice operation instruction. The convenience of selecting the two radio station modes is improved, and meanwhile, the stability and the safety of a user in driving are effectively improved.
