Embodiment 1

[0027] This example discloses a smart walk alarm mainly consisting of a motion information acquisition chip, a smart tracing module, a GPS positioning module, a single-chip CPU control module, a SIM information transmission module, a camera, and a WiFi network transmitting module, and a wireless remote control device.

[0028] Its workflow figure 1 As shown, the vehicle is in the normal travel process, the GPS module mounted in the warning is in a hot standby state, and the vehicle motion information collector collects the vehicle acceleration data at fixed time intervals.

[0029] When an accident occurs, the information acquisition is obtained from the three-axis direction (500 ms) to the acceleration of the peak. The peak acceleration reaches the set threshold, automatically issues, and stores the type of accident type according to the acceleration value to discriminate the incident type, waiting for the next command. After the device issues an alert, if no one is an interrupt ...

Embodiment 2

[0035] In the present embodiment, the warning sign identifies the white solid line of the vehicle sides and realizes autonomous driving through the infrared tracing module. After the traffic accident occurs, it prevents the driver from hazardous in the process of launching alarm in reverse walking.

[0036] The autonomous tracing of the warning sign is mainly mainly 51 single-chip microcomputer (see the schematic diagram figure 2 ), Infrared pairing function unit L298N drive module, drive motor (for motor drive circuit schematic Figure 5 ), Power supply, etc., its digital tube display circuit is like Image 6 Indicated.

[0037]The tracking module mainly adopts infrared detection. Two infrared emissions and reception pairs are used on both sides on the front of the warning card. The infrared tube is constantly transmitting infrared rays in the operation. When the warning is driven from the edge of the car row, it is about to deviate. The laterally detected endless signal is detecte...

Abstract

The invention relates to the technical field of intelligent transportation, in particular to an intelligent walking warning board for expressway accident early warning and self-help seeking. The intelligent walking warning board comprises a motion information acquisition chip, an intelligent tracing module, a GPS positioning module, a singlechip CPU control module, a SIM information transmission module, a camera, a WIFI network transmission module and a wireless remote control device. An intelligent walking warning board device with the functions of intelligent tracing, independent positioning, video transmission, information transmission, wireless recovery and the like is designed from the two angles of expressway accident early warning and emergency rescue by utilizing the technologies of singlechip development, GPS positioning, vehicle movement information acquisition, communication, wireless retraction and the like, early warning and timely rescue after expressway accidents are realized, the defects of danger in the placing process, unobvious warning effect, inability to timely asking for help and the like of a traditional triangular warning board are overcome, and the creativity is high.

Description

Technical field [0001] The present invention relates to the field of intelligent traffic, and specific to highway accident warnings and autonomous rescue intelligence walking alerts. Background technique [0002] With the growth of my country's economic strength, the increase in per capita income is steadily rising, and the highway has high linear standards, high road quality, high vehicle speed, small interference, closed management, less accident, safety The advantages of sexuality have become the first choice for the mode of travel. However, once the motor vehicle accident occurred, its accident is not only serious, but also interferes with the normal operation of the highway, often causes multiple secondary accidents or secondary disasters, leading to the stage of highway. In recent years, the highway has repeatedly seriously issued a large secondary traffic accident, which seriously jeopardizes the safety of the people's lives and property, and has brought great pressure to ...
