The road operation warning method is taken as an invention point of the embodiment of the disclosure, and solves the technical problem three of the reduction of the safety degree of the road operation in the background art. Factors that cause the reduction of the safety of road work are often as follows: the video is shot by the camera to detect the vehicle to be intruded, under the condition of severe environment, the definition of the shot video is reduced, the accuracy of detecting the vehicle to be intruded is reduced, and therefore the accuracy of alarming to road operators is reduced. If the above factors are solved, the safety of the road work can be improved. To achieve this, the road work warning device included in the present disclosure may first acquire an initial communication address table. And secondly, updating the initial communication address table to obtain the communication address table of the portable device. Thus, the information of the portable device bound with the remote monitoring device can be updated in time so as to facilitate subsequent communication with the portable device. Then, the portable device communication address table is stored in a storage device. Therefore, the communication address of the carrying device can be stored in time, so that the communication can be established with the carrying device in time when the road operation warning equipment is used next time. Then, road vehicle speed information and warning device vibration information are collected. Therefore, the intrusion of the vehicle can be characterized by the speed information of the road vehicle and the vibration information of the warning equipment. Then, in response to determining that the road vehicle speed information satisfies a preset speed condition and the warning device vibration information satisfies a preset vibration condition, generating accident warning information based on the carrier communication address table, and transmitting the preset warning information to each of the carriers in the carrier assembly to perform a first warning operation by the carrier. Therefore, after the vehicle is detected to be intruded, the monitoring camera is started to shoot images, accident information is obtained, and meanwhile, the portable device is warned. And finally, the accident alarming information is sent to the traffic management terminal to execute a second alarming operation. Therefore, the traffic management terminal can alarm according to the accident alarm information. Therefore, even under the condition of severe environment, the road operation warning device can still detect the intruded vehicle through the radar sensor and the collision detection sensor, and after the intruded vehicle is detected, the camera is started to start shooting, so that the accuracy of detecting the intruded vehicle can be improved, the accuracy of warning the road operation personnel can be improved, and the safety of the road operation can be improved.
