Embodiment 1

[0024] See figure 1 , figure 2 , the vehicle-mounted broadcasting system provided by the present invention includes a vehicle-mounted wireless receiving part and a background wireless transmitting center, and the vehicle-mounted wireless receiving part includes a main processor, a memory connected to the main processor, a wireless receiving device and a broadcasting device, and the vehicle-mounted wireless receiving part The receiving part is wirelessly connected with the background wireless transmitting center through the wireless receiving device, and the main processor is connected with the vehicle start key switch circuit.

[0025] The on-board wireless receiving part is working 24 hours a day. When there is no one in the car, if the background wireless transmitting center transmits wireless information, the wireless receiving device installed on the car will first receive the wireless information and store it in the memory. After the ACC power supply of the vehicle is t...

Embodiment 2

[0029] Connect the main processor with the GPS module (or Beidou module), such as image 3 As shown, because the GPS module can receive GPS satellite signals, and calculate the location of the vehicle. At the same time, the built-in program of the main processor has a communication agreement with the background wireless transmission center, which stipulates that certain types of information can only be played within the scope of the region. For example, if the road condition information played on the radio is associated with a road section in a certain area, the information must be obtained by vehicles within the area to be effective. Vehicles outside the area do not. In this way, when the vehicle is running, because the GPS module has a positioning function, if the main processor knows that the vehicle is located in the area through calculation, its main program controls the speaker on the car to automatically play the road condition information, so as to remind the driver. ...

Embodiment 3

[0031] Connect the main processor with the display, such as Figure 4 As shown, if the background transmitting device transmits video information, the wireless receiving devices of several vehicles will store the video information in the memory of the main processor after receiving it. With the cooperation of the driver, the purpose of prompting the driver is achieved.

Abstract

The invention discloses a vehicle-mounted broadcasting system and a broadcasting method thereof. The vehicle-mounted broadcasting system comprises a vehicle-mounted wireless receiving part and a background wireless emission center, wherein the vehicle-mounted wireless receiving part comprises a main processor, and a memorizer, a wireless receiving device and a broadcasting device which are connected with the main processor; the vehicle-mounted wireless receiving part is in wireless connection with the background wireless emission center by the wireless receiving device; the main processor is connected with a vehicle starting key switching circuit. When a starting key is inserted and a driver exists in a vehicle, wireless information emitted by the background wireless emission center is automatically played and the driver does not need to switch on an additional playing switch, so that the information can be effectively listened and the aim of effectively reminding is achieved. The information related to vehicle positions is selectively and automatically played according to different vehicle driving positions, and the vehicle driving is facilitated.

Description

technical field [0001] The invention belongs to the technical field of car broadcasting, and in particular relates to a car broadcasting system and a playing method thereof. Background technique [0002] At present, car radios are installed on cars, which bring convenience to people's travel: for example, when the car radio is turned on, the car owner can listen to radio programs and traffic information on road conditions. However, existing car radios have some disadvantages, that is, they can only be listened to passively by users. For example: when the radio station is playing, the radio will listen to it; if the radio station broadcasts any information, all radios with the same frequency can only listen to that information. This brings about some defects, such as: Sometimes, when the radio station broadcasts traffic congestion information, the car owner does not turn on the radio when driving, or turns on the radio and is listening to other radio programs, the car owner ...
