When in use, the warning sign configured with the vehicle fault warning device is placed by the user behind the faulty vehicle, and the location determined by the positioning module 2 during positioning is the current location of the faulty vehicle.

The message processing module 3 is used to generate a warning message based on the current position. Wherein, the warning message includes the current location. For example, the warning message may be "An accident occurred at position XX" to remind the driver of the vehicle that received the warning message to pay attention when driving to position XX Safety.

The FM full-channel broadcasting equipment 4 is used to send the warning message in a full-channel broadcasting manner through the antenna 1 so that the broadcasting equipment of other vehicles can receive the warning message. It is understandable that the FM full-channel broadcasting device 4 transmits a broadcast signal, and the warning signal is carried in the broadcast signal. interest. The FM full-channel broadcasting device 4 sends the warning message in a full-channel broadcasting manner. The full-channel broadcasting can cover the content being broadcast by the broadcasting equipment of other vehicles, and make the broadcasting equipment of other vehicles broadcast the warning. Information, for drivers of other vehicles, they can learn that there is a faulty vehicle in a certain position through the vehicle’s broadcast, and learn the fault situation ahead before driving to the location of the faulty vehicle, which makes driving When driving to the location of the faulty vehicle, the operator can more carefully check the surrounding road conditions, so that the faulty vehicle can be accurately identified and accidents can be avoided.

For example, the content of the broadcast authentication request may be "there is a vehicle failure at position XX, please assist in the authentication".

The V2X communication module 5 is configured to send the broadcast authentication request to a peripheral device supporting V2X communication, and receive a broadcast authentication confirmation message returned by the peripheral device. Peripheral equipment can be vehicles with V2X functions or roadside facilities. After receiving the broadcast authentication request, the peripheral device can use its own camera device to perform visual identification to determine whether there is really a faulty vehicle at position XX. If it is, it is confirmed that it can be authenticated. At this time, the peripheral device returns a broadcast authentication confirmation message to The V2X communication module 5. When the V2X communication module 5 receives the broadcast authentication confirmation message, which indicates that FM coverage broadcasting is possible, the message processing module 3 generates the warning message again, and uses the FM full-channel broadcasting device 4 Send it.

Those with ordinary knowledge in the technical field can understand that V2X technology is the core technology of the Internet of Vehicles and the key technology of the future intelligent transportation system.

Remind the driver on it to pay attention. However, for other vehicles that do not support V2X communication, it is necessary to use the FM full-channel broadcasting device 4 to send a cover station broadcast to achieve the purpose of reminding the driver to pay attention.

In addition, in practical applications, it may happen that the positioning module 2 cannot be accurately positioned or cannot be positioned. It is understandable that whether the positioning of the positioning module 2 is accurate can be based on the positioning signal (such as GPS signal) received by the positioning module 2. ). When the GPS signal is too weak, it may cause erratic positioning. At this time, the message processing module 3 may also be used to generate a positioning assistance request when the current position obtained by the positioning module 2 is not accurate or the positioning module 2 cannot be positioned.

The V2X communication module 5 may also be used to send the positioning assistance request to the peripheral device, and receive the current position of the faulty vehicle returned by the peripheral device. Specifically, after the peripheral device receives the positioning assistance request, it can use its own camera device to perform visual recognition to confirm whether there is a faulty vehicle nearby, and if there is, determine it based on its own location and the relative location of the faulty vehicle to itself The current location of the faulty vehicle, and the determined current location of the faulty vehicle is returned to the V2X communication module 5. After the V2X communication module 5 receives the current location of the faulty vehicle returned by the peripheral device, the message processing module 3 can generate a warning message based on the current location of the faulty vehicle returned by the The FM full-channel broadcasting device 4 transmits.

Further, the antenna may be a directional antenna, and the directional antenna is preset with a transmission direction and a transmission distance. For example, the directional antenna may be a matrix antenna or a horn antenna.

The FM full-channel broadcasting device 4 may be specifically used to send the warning message to other vehicles in the transmitting direction and within the transmitting distance by means of the directional antenna in a full-channel broadcasting manner.

Generally speaking, the broadcast signal transmitted by the FM full-channel broadcasting device 4 only needs to be received by other vehicles behind the malfunctioning vehicle. Therefore, a directional antenna is used and the transmission direction of the directional antenna is toward the rear of the vehicle. The problem of misinformation can be avoided. It should be noted that for the vehicle failure warning device set on the warning sign, if the directional antenna is fixed relative to the warning sign, in this case, if it is to be oriented towards the rear of the malfunctioning vehicle To transmit a broadcast signal, the user needs to place the directional antenna toward the rear of the malfunctioning vehicle when placing the warning sign.
