According to various embodiments, the storage device 130 may process and store the vehicle data (vehicle data 1, vehicle data 2, . . . vehicle data n) collected from the plurality of vehicles 10.
For example, the storage device 130 may accumulate and average the vehicle data (vehicle data 1, vehicle data 2, . . . vehicle data n) collected from the plurality of vehicles 10 for a preset period, and may compress and store the accumulated and averaged data as single data.
The preset period may be varied in consideration of an amount of vehicle data collected from the plurality of vehicles 10 and an opportunity cost of freshness of the data.
According to an embodiment, the storage device 130 may classify the vehicle data (vehicle data 1, vehicle data 2, . . . vehicle data n) collected from the plurality of vehicles 10 depending on a location or a broadcasting channel, and then may accumulate and average a set frequency for receiving the same channel at the same location and the broadcasting reception quality depending on the set frequency.
By referring to the accumulated data, the reception quality in the case of receiving a specific broadcasting channel using a specific frequency at the same location may be confirmed.
As such, the system 100 may convert the vehicle data (vehicle data 1, vehicle data 2, . . . vehicle data n) collected from the plurality of vehicles 10 into big data and store the big data in the storage device 130.
The at least one processor 120 may determine an optimal frequency depending on a location for each broadcasting channel based on the vehicle data (vehicle data 1, vehicle data 2, . . . vehicle data n) collected from the plurality of vehicles 10 stored in the storage device 130 (1200).
According to various embodiments, at least one processor 120 may determine an optimal frequency depending on a location for each broadcasting channel based on a set of data (hereinafter ‘accumulated data’) in which the vehicle data (vehicle data 1, vehicle data 2, . . . vehicle data n) collected from the plurality of vehicles 10 stored in the storage device 130 are processed and stored (hereinafter ‘big data’).
Referring to
According to various embodiments, the storage device 130 may store an optimal frequency table for receiving the first broadcasting channel.
The optimal frequency for receiving the first broadcasting channel may be different depending on latitude and longitude.
In an embodiment, the at least one processor 120 may determine, as an optimal frequency, a frequency classified as having the highest reception quality for the first broadcasting channel for a specific location, that is, having the largest electric field strength value versus noise value.
For example, the optimal frequency for receiving the first broadcasting channel at a first location (e.g., latitude 35.103228/longitude 128.091845) may be determined to be 91.9 (MHz), and the optimal frequency for receiving the first broadcasting channel at a second location (e.g., latitude 35.103228/longitude 128.091844) may be determined to be 99.7 (MHz).
In other words, the at least one processor 120 may determine, based on the vehicle data collected from the plurality of vehicles 10, a first frequency for receiving the first broadcasting channel with the highest reception quality at the first location, and may determine a second frequency for receiving the first broadcasting channel with the highest reception quality at the second location.
The storage device 130 may store an optimal frequency table depending on a location for each broadcasting channel (1300).
Referring to
A form/format of the data described through
The system 100 according to an embodiment may provide useful information for user convenience by collecting vehicle data from the plurality of vehicles 10 in real time and processing the collected vehicle data to obtain useful data.
Hereinafter, an embodiment in which the system 100 provides optimal frequency information depending on a location for each broadcasting channel to the vehicle 10 and the vehicle 10 changes the frequency of the broadcast receiver 12 without user intervention will be described.
According to various embodiments, the system 100 may deliver information on an optimal frequency for each location for receiving a specific broadcasting channel with the highest quality to the vehicle 10.
For example, the system 100 may transmit information on the first frequency for receiving the first broadcasting channel with the highest reception quality at the first location, and information on the second frequency for receiving the first broadcasting channel with the highest reception quality at the second location, to the first vehicle 10.
For example, the at least one processor 120 may control the communicator 110 to transmit information on the first frequency and information on the second frequency to the first vehicle 10.
In this case, the first vehicle 10 may be a vehicle with a history of receiving the first broadcasting channel, a vehicle currently receiving the first broadcasting channel, or a vehicle in which the first broadcasting channel is registered as a favorite.
For convenience of explanation, locations having different latitudes or longitudes are classified into the first location and the second location, and in addition to information on the first frequency or the second frequency, the system 100 may transmit information on a frequency (e.g., a third frequency, a fourth frequency, . . . a Nth frequency) for receiving the first broadcasting channel with the highest quality in another location (e.g., a third location, a fourth location, . . . a Nth location), to the first vehicle 10.
Referring to
The telematics device 11 of the vehicle 10 may transmit the destination information set by the user and the location information of the vehicle 10 to the system 100 (S2).
The system 100 may set at least one route for reaching the destination from the current location of the vehicle 10 in consideration of various external factors (e.g., road traffic situation, weather, road type) (S3).
Specifically, the at least one processor 120 may set at least one route for reaching the destination from the current location of the vehicle 10 based on the external information obtained through the communicator 110, the location information of the vehicle 10, and the destination information.
According to various embodiments, the system 100 may set various routes, such as a first route to reach the destination with a minimum distance, a second route to reach the destination with the least amount of time, and a third route to reach the destination with a minimal toll.
The system 100 may determine a change section in which the location of the vehicle 10 is changed from the first location to the second location on the set route (S4).
In this case, the first location and the second location may refer to two different points on the set route and where a difference between the optimal frequency values for receiving the first broadcasting channel is greater than a preset value.
In other words, when a difference between a first optimal frequency for receiving the first broadcasting channel at the first location and a second optimal frequency for receiving the first broadcasting channel at the second location is greater than the preset frequency, the system 100 may determine a section in which the location of the vehicle 10 is changed from the first location to the second location as the change section.
According to various embodiments, the preset frequency may be set in consideration of noise due to frequent frequency change and opportunity cost of quality improvement due to frequency change.
The system 100 may transmit information on the set route and information on the change section to the vehicle 10 (S5).
Specifically, the at least one processor 120 may control the communicator 110 to transmit information on the set route and information on the change section to the vehicle 10.
In this case, the information on the change section may include location information of the change section and frequency information (e.g., information on the second frequency) to be changed in the change section.
When the vehicle 10, which has received the information on the set route and the information on the change section, enters the change section, the vehicle 10 may automatically change the frequency of the broadcast receiver 12 without user intervention.
In an embodiment, the control circuit of the broadcast receiver 12 may automatically change the set frequency when the vehicle 10 enters the change section.
Referring to
The vehicle 10 may receive, from the system 100, information on a first change section D1 that is changed from the first location (e.g., path A) to the second location (e.g., path B) on the set path and information on the second frequency (99.7 MHz), as well as a set path.
Also, the vehicle 10 may receive information on a second change section D2 that is changed from the second location (e.g., path B) to the third location (e.g., path C) on the set path and information on the third frequency (100.5 MHz).
When the vehicle 10 passes through the second change section D2, the vehicle 10 may control the broadcast receiver 12 to change the set frequency set to 99.7 MHz to 100.5 MHz.
According to various embodiments, the at least one processor 120 may also control the communicator 110 to transmit a control command for changing the frequency of the broadcast receiver 12 to the vehicle 10 in the change section. That is, the system 100 may directly change the set frequency of the broadcast receiver 12.
When the frequency is automatically changed, the vehicle 10 may notify the user through the display device and/or the speaker that the set frequency of the broadcast receiver 12 is automatically changed.
As such, the vehicle 10 according to an embodiment automatically changes the set frequency of the broadcast receiver 12 in the change section on the set path based on the information received through the system 100, thereby improving user convenience.
According to various embodiments, the at least one processor 120 may control the communicator 110 to transmit information on the first frequency to the first vehicle 10 in response to the first vehicle 10 being driven at the first location, and may control the communicator 110 to transmit information on the second frequency to the first vehicle 10 in response to the first vehicle 10 being driven at the second location
That is, the system 100 may also provide information on an optimal frequency for receiving a specific broadcasting channel at the current location of the vehicle 10 in real time.
Depending on the method and system 100 for providing a broadcast signal frequency according to an embodiment, by using big data, the optimal frequency for receiving a specific broadcasting channel may be determined depending on the exact location.
Rather than transmitting the optimal frequency information at all locations, by matching with the set path of the vehicle 10 and transmitting only information on the frequency change section, unnecessary information exchange between the system 100 and the vehicle 10 may be prevented.
An example of a method and system for providing a broadcast signal frequency is not limited thereto, and the embodiments described above are exemplary in all respects. Therefore, a person having ordinary skill in the technical field to which the disclosure belongs will be able to understand that the disclosure may be implemented in other specific forms without changing the technical idea or essential characteristics thereof. The scope of the disclosure is set forth in the claims rather than in the foregoing description, and all differences within the scope equivalent thereto should be construed as included in the disclosure.
Herein, the disclosed embodiments may be implemented in the form of a recording medium storing instructions executable by a computer. The instructions may be stored in the form of program code, and when executed by a processor, a program module may be created to perform the operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.
The computer-readable recording medium includes various kinds of recording media in which instructions which may be decrypted by a computer are stored. For example, there may be a read only memory (ROM), a random access memory (RAM), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, and the like.
As is apparent from the above, according to various embodiments of the present disclosure, a safety accident that may occur as a user manually changes a broadcast signal frequency while driving can be prevented in advance.
Further, the present disclosure can determine an optimal broadcast signal frequency at an accurate location by using big data, and thus can provide an optimal broadcasting quality to the user.
