Step S20, sending real-time status and road condition data to the cloud server;

In step S30, the cloud server determines whether a traffic accident occurs, and if a traffic accident occurs, the judgment result is sent to the display end.

The monitoring device acquires the real-time status of the guardrail and the road condition data of the road. The real-time status of the guardrail is whether the guardrail is deflected, and if so, what is the deflection parameter, determining whether the guardrail is damaged by the impact; the road condition data of the road is the vehicle of the road section. The number and the speed of the car, so as to know whether there is a car parked in the road section; subsequently, the real-time status of the guardrail and the road condition data of the road are sent to the cloud server; after receiving the relevant data, the cloud server performs data processing to determine the Whether there is a traffic accident on the road section. If a traffic accident occurs, the judgment result of the occurrence of the traffic accident is sent to the display end. If there is no traffic accident, there is no need to send the judgment result.

Among them, the road generally has the characteristics of long travel, and it is necessary to divide each road into a monitoring area, which spans 500 meters. Of course, the distance varies with the signal transmission distance of the monitoring device; then, monitoring is placed in each monitoring area. The monitoring device comprises a central control module, a gyro module, a Doppler microwave module and a Bluetooth module, wherein the module is installed in a box, or the central control module, the Doppler microwave module and the bluetooth module are mounted in a box In the box body, the gyro module is another independent box; the central control module controls the gyro module to obtain the real-time state of the guardrail, and the gyro module is used for monitoring the angular velocity of the guardrail in the three-axis direction and judging the impact and the dumping state, thereby Determine whether there are cars, animals or other objects hitting the guardrail, and control the Doppler microwave module to obtain road condition data to determine whether there are vehicles parked in the road. The Doppler microwave module includes a microwave transmitter, a microwave receiver and a micro processor. The microwave transmitter transmits a microwave signal to the monitoring area through an antenna, and the microwave receiver receives the microwave signal when there is no moving target in the monitoring area. The signal frequency is the same as the transmitted signal frequency. When there is a moving target, the frequency of the microwave signal reflected by the target will shift due to the Doppler effect, and the microprocessor is analyzed to obtain the number of cars and the speed of each vehicle.

Preferably, the Bluetooth module is a Bluetooth 5.0mesh module, and the Bluetooth 5.0mesh module has a wider coverage and a faster transmission speed for low-power devices.

If it is determined that the real-time status of the guardrail is abnormal, for example, the guardrail is damaged by the impact, and the abnormal information is reported to the cloud server, the gyro module Enters sleep mode when not in an abnormal state, waiting for periodic wakeup.

Alternatively, the gyro module is provided with a memory, and the memory stores a plurality of abnormal states. The gyro module always acquires the real-time state of the guardrail, and compares the real-time state of the acquired guardrail with the abnormal state, and obtains the real-time status of the guardrail when In the abnormal state, the abnormal information is reported to the cloud server. The gyro module enters the sleep mode when the abnormal state is not abnormal. When the abnormal information is detected, the vehicle wakes up automatically in the event of a traffic accident.

In this embodiment, the road condition data is provided with a plurality of level information, the level information includes at least a traffic jam level, a slow driving level, and a normal driving level; and the Doppler microwave module acquires road condition data of the road, that is, acquires a road. The number of vehicles and the speed of each vehicle to determine the level of road condition data; wherein, when the cloud server obtains abnormal information, the road condition data is the traffic jam level, for example, each vehicle is slow to travel, and most of the vehicles have zero speed, and the judgment is made. When a cloud server obtains abnormal information, the road condition data is a slow level. For example, if each vehicle travels slowly and some vehicles have zero speed, it is judged that an ordinary traffic accident occurs; when the cloud server obtains abnormal information, the road condition The data is of a normal level, for example, if the driving speed of each vehicle is normal, it is judged that the traffic accident has been handled, or that the vehicle in which the traffic accident has occurred is stopped in the emergency lane next to it. By analyzing the road condition data, the cloud server can send the level information of the road condition data to the management department or the driver. The management department can arrive at the scene for traffic command and deal with the traffic accident, and timely repair the guardrail; the driver can detour To avoid more serious traffic jams on the road.

The real-time status is set with a plurality of level information, and the level information includes at least a slight level and a severity level, and the severity of the traffic accident is determined by the real-time status of the guardrail; wherein, when the cloud server obtains the abnormal information, When the level is slight, for example, the guardrail is only slightly collided, the damage is not serious, and the ordinary traffic accident is judged; if the cloud server obtains the abnormal information and is of a serious grade, for example, the guardrail is seriously collided, the damage is extremely serious. Determine that a serious traffic accident has occurred.

Further, referring to FIG. 3, the sending the real-time status of the guardrail and the road condition data of the road to the cloud server specifically includes the following steps:
