Description

Technical Field

[0001] The utility model belongs to the technical field of traffic safety and accident warning, and particularly relates to an intelligent warning system for a pre-warning section of a high-risk road section on a highway. Background Technique

[0002] Affected by natural disasters (such as landslides, earthquakes, floods, mudslides, storms, etc.) and accidental loads (such as explosion forces, impact forces, etc.), the traffic safety and structural stability of road facilities will be damaged. Road facilities include some or all of elements such as roadbeds, road surfaces, slopes, bridges, tunnels, culverts, etc. Severely damaged road facilities affect the safety of vehicle driving. Therefore, it is necessary to monitor them, especially high-risk road sections, to improve safety. Existing technologies mostly monitor the health status of road facilities (such as the monitoring of operating bridges), report the monitoring data to the control center, and the control center determines the safety based on the uploaded data and announces the determination results through official websites and information platforms. Specifically, editing text is required to announce on the official website, and at the same time, drivers need to log in to the website to view in order to obtain information; automatic early warning usually needs to be reported to operation departments, management departments, traffic management departments, etc. after manual intervention. After multiple accident analyses, there is a phenomenon of disconnection or lag in on-site traffic safety management and warning management in the first time after an accident occurs. The on-site drivers who should have obtained warning information first do not obtain it in time, often resulting in more serious secondary accidents.

[0003] In summary, there is a large time difference between the existing warning system monitoring data and the public knowing the results, resulting in the failure or untimely warning, insufficient on-site warning management, and prone to more serious secondary accidents.

[0027] Embodiment of the intelligent warning system for the pre-warning section of high-risk road sections:

[0028] AsFigures 1-3 As shown, the intelligent warning system for the pre-warning section of the high-risk road section of the highway includes a monitoring unit, a warning unit, a LoRa controller, a power supply unit, and traffic poles 2 arranged on both sides of the road. The LoRa controller is respectively connected to the monitoring unit and the warning unit by signals, and the above-mentioned power supply unit is respectively connected to the monitoring unit, the warning unit, and the LoRa controller for power supply. Figure 3 Only two traffic poles 2 are shown in [Figure], and the other traffic poles 2 are not drawn. The monitored road includes bridges 1, tunnels, high-risk slopes, high-fill roads, etc. In this embodiment, the monitored road is taken as an example of bridge 1 for illustration.

[0029] Specifically, the monitoring unit includes a camera 3, a stress sensor, a displacement sensor, and a fracture monitoring device; the above-mentioned camera 3 is arranged on the traffic pole 2 for obtaining image data of the road and vehicles on the road; the above-mentioned stress sensor is arranged at the monitoring points of the road for obtaining stress data of the road to realize the monitoring of the road load; the above-mentioned displacement sensor is arranged at the monitoring points of the road for obtaining the oscillation data of the road; the above-mentioned fracture monitoring device includes a monitoring body wire 4 and a multimeter. The above-mentioned monitoring body wire 4 is fixed in the length direction of the road, and the on-off measurement circuit of the multimeter is connected to the monitoring body wire 4 for obtaining the on-off state of the monitoring body wire 4 to realize the monitoring of the fracture state of the road. Since the monitoring body wire 4 is fixed on the road, when the monitored road section breaks, the corresponding monitoring body wire 4 will also break, and the electrical data measured by the multimeter will change, and thus the fracture situation of the monitored road section can be known accordingly.

[0030] The warning unit includes a flash visual alarm device 5, a sound alarm device 6, a laser beam visual alarm device, and an alarm information board 9; the above-mentioned flash visual alarm device 5 is arranged on both sides of the road; the above-mentioned sound alarm device 6, laser beam visual alarm device, and alarm information board 9 are all arranged on the traffic pole 2; the above-mentioned traffic pole 2 is arranged in the monitored road section and the pre-warning section. The above-mentioned pre-warning section refers to the non-monitored road section within a set length from the monitored road section. The range of this set length is [800m, 1200m]. Preferably, the set length is 1000m. Among them, in order to achieve a better warning effect, the flashing frequency range of the flash visual alarm device 5 is [2.5Hz, 3Hz], and the brightness ≥ 5000cd / m 2, during an accident, these high-brightness and high-frequency flashing lights will ensure that the driver is strongly impacted visually and quickly attracts their attention. To reasonably plan the installation cost of the traffic pole 2, the traffic pole 2 is installed at an interval of 100 meters. Considering the height range of vehicles and the field of vision of drivers, the height range of the traffic pole 2 from the road ground is [3m, 20m]; within this height range, drivers can more easily perceive the warning signals of various warning devices on the traffic pole 2.

[0031] The warning message board 9 can display warning words such as "Danger ahead, please slow down!" and "Danger, please stop!". The sound warning device 6 can emit a special rhythm sound for warning or broadcast a warning voice prompt to enhance the auditory warning effect through the sound warning device 6, enabling the driver to clearly perceive potential dangers.

[0032] To ensure the stability of power supply, the power supply unit includes a first power source and a second power source. To ensure the environmental protection of power supply, both the first power source and the second power source include a battery power source and a solar power source; some of the solar panels 10 of the above solar power source are installed on the top of the traffic pole 2.

[0033] To relieve the driver's visual fatigue, the flashing visual warning device 5 includes linear lamps and dot lamps. Through the diverse flashing visual warning device 5, it is convenient for the driver to judge the driving state of the vehicle. The laser beam visual warning device includes a laser 7, and the above laser 7 emits a laser beam 8 obliquely towards the opposite side of the road. Since the traffic poles 2 are installed on both sides of the road, the laser beams 8 emitted by two opposite lasers 7 will form a shape of laser beam 8 intersection, providing a visual blocking effect for the driver and ensuring the warning effect of the laser beam visual warning device. According to different monitoring results of the monitoring unit, the warning unit performs different warning combinations to ensure the accuracy of the warning effect.

[0034] To achieve a better warning effect and make the warning signal reach the driver quickly, the sound warning device 6 uses a high-decibel sound alarm.

[0035] To ensure more accurate monitoring results, the above monitoring body wire 4 includes multiple segments, and each segment of the monitoring body wire 4 is connected to an independent multimeter on-off measurement circuit. In this way, one segment of the monitoring body wire 4 corresponds to one section of the road, and the corresponding fault monitoring road section can be accurately located through the monitoring body wire 4.

[0036] To ensure that the road information center can quickly obtain the data of each monitored road, the LoRa controller is also used to connect to the road information center and is used to upload the data obtained by the monitoring unit to the road information center and other management terminals.

[0037] This warning system forms an all-round and multi-level warning network through the multi-modal fusion of various physical signals, significantly improving the warning effect. The system has an automatic start function; in case of a failure, it can not only start automatically but also be manually started by personnel. When an accident or other disaster occurs, the pre-warning section is placed in front of the critical section, and through an efficient linkage control mechanism, the rapid transmission and execution of warning information are ensured, so as to gain more response time for drivers.

[0038] The above are only the preferred embodiments of the present invention, and do not impose any limitations on the present invention. Any simple modifications, changes, and equivalent structural changes made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
