The embodiment describes how a signal transmitting station converts a security early warning data packet into broadcast information for broadcasting. For example, the traffic safety warning information to be issued is road traffic accident information and severe weather information such as rain and snow, and because the traffic accident has the characteristics of being sudden and temporary, the traffic safety warning information about the road traffic accident is set as the traffic safety warning information to be issued in real time, and the traffic safety warning information about the weather is set as the traffic safety warning information to be issued at the moment after the traffic safety warning information about the road traffic accident is issued. After receiving the safety early warning data packet, the signal transmitting station sends the safety early warning data packet about the road traffic accident to be issued in real time to the processor, the processor converts the safety early warning data packet into a broadcast message to be transmitted, the weather safety early warning data packet which is not required to be issued in real time is stored in an information storage of the signal transmitting station, the information storage is transmitted to the processor through a data transmission circuit at a specified time, and the processor converts the safety early warning data packet into the broadcast message to be transmitted.
According to the embodiment, the traffic safety early warning information is classified according to the emergency degree and is issued in time intervals, and the early warning information with higher emergency degree is preferentially sent, so that a traveler can timely acquire the early warning information and take measures to really play a real-time early warning role of traffic safety early warning. The traffic safety early warning method has the advantages that the issue of a large amount of traffic safety early warning information is avoided, the early warning information with low emergency degree covers the early warning information with high emergency degree, and when a traveler learns the relevant early warning information, the traveler cannot take countermeasures before, so that the traffic safety early warning effect is difficult to play. In addition, in the embodiment, the safety precaution information is converted into the broadcast information to be issued, the transmission of the broadcast information is not limited by natural conditions such as fog, rain, snow and the like, and the related traffic safety precaution information can be transmitted to the travelers in time even in severe weather.

When a certain device cannot work normally, the operation of the whole system is affected, and traffic safety early warning information cannot be sent out. For example, if the information receiver of the signal transmitting station fails, the signal transmitting station cannot receive the traffic safety warning data packet sent by the central control station, and the traffic safety warning information cannot be converted into broadcast information for broadcasting. In order to avoid that a certain device fails and normal operation of the whole system is affected, in this embodiment, a data request is actively initiated within a certain time interval by setting an encoder in an information recorder of a signal transmitting station, so as to obtain a working state of each device in the signal transmitting station, determine whether each device is working normally, find problems existing in the device in time, feed back maintenance information to a central control station, notify a user of maintenance, and ensure normal operation of the system.
