Description

Technical Field

[0001] This application relates to the field of highway technology, and in particular to a highway early warning device. Background Technology

[0002] As highways age, roadbeds, pavements, ditches, slopes, and supporting facilities suffer varying degrees of damage. This leads to a continuous increase in the frequency of road maintenance and repair work requiring road closures. Because road closures necessitate both lane closures and traffic control zones while maintaining normal road operation, traffic becomes narrower and less efficient. Furthermore, high traffic volume and speeds significantly disrupt roadwork, creating substantial traffic safety risks and increasing the risk of accidents, posing a serious threat to the lives of construction workers.

[0003] Currently, the main methods for warning vehicles during road construction on existing highways are installing flashing warning devices in traffic control zones and placing warning signs such as "Construction Ahead" and "Slow Down" at both ends of the construction section. These protective measures can only prevent vehicles from accidentally entering the warning area and causing injury to on-site construction workers, thus avoiding accidents. However, these measures are not very effective and are easily vandalized. Moreover, on-site construction workers can only warn drivers from a distance by wearing simple reflective vests, and cannot directly warn on-site construction workers. If a vehicle accidentally enters the warning area at high speed, the construction workers may not be able to avoid it in time, leading to an accident.

[0004] Therefore, this application provides a highway early warning device to solve the above-mentioned problems. Utility Model Content

[0005] To address the aforementioned problems, this application provides a highway early warning device. Building upon existing road construction safety warnings, it adds a more direct and effective forward warning device to the front end of the traffic control area for on-site construction personnel. The technical solution is as follows:

[0006] This application provides a highway early warning device, including an intelligent early warning robot and an intelligent early warning vest. The intelligent early warning robot is used to detect vehicles or people accidentally entering the road ahead of construction. It includes a main controller and a camera module, a lidar module, and an audible and visual alarm component electrically connected to the main controller. The camera module includes a front-facing camera for monitoring road conditions in the direction of oncoming traffic at the construction site and a rear-facing pan-tilt camera for monitoring the construction situation. The lidar module is used to detect vehicles or people accidentally entering the road within its range ahead of the construction site. The intelligent early warning vest is worn by construction personnel and is equipped with a vest alarm component. The intelligent early warning vest is communicatively connected to the intelligent early warning robot and triggers an alarm in conjunction with the audible and visual alarm component of the intelligent early warning robot.

[0007] For example, in one embodiment of the highway warning device, a communication antenna is provided on the intelligent warning robot, and a receiving antenna is provided on the intelligent warning vest to receive control signals emitted by the intelligent warning robot.

[0008] For example, in one embodiment of the highway early warning device, the audible and visual alarm component includes fog lights, a voice broadcasting system, strobe lights, and a display module, so as to provide audible, visual, and textual warnings when the lidar module detects a vehicle or person mistakenly entering within the range in front of the construction site.

[0009] For example, in one embodiment of the highway warning device, the vest alarm component includes a waterproof buzzer, a waterproof vibration module, and a light, so as to simultaneously emit sound, light, and vibration warning information after the smart warning vest receives the warning signal from the smart warning robot.

[0010] For example, in one embodiment of the highway warning device, a wireless communication control box is also provided on the smart warning vest, through which the waterproof buzzer, the waterproof vibration module and the light lamp are controlled to turn on and off.

[0011] For example, in one embodiment of the highway warning device, the receiving antenna is a flexible antenna that matches clothing, and a filtering circuit is provided within the receiving antenna.

[0012] For example, in one embodiment of the highway early warning device, the intelligent early warning robot includes a body with a front surface facing the direction of oncoming traffic and a rear surface facing the construction site. The sound and light alarm component is disposed on the front surface of the body to warn vehicles or personnel that may accidentally enter the construction site. The camera module and the lidar module are disposed on the top of the body, with the front camera and the lidar module facing the front surface of the body and the rear pan-tilt camera facing the rear surface of the body.

[0013] For example, in one embodiment of the highway early warning device, a universal joint is provided on the top of the body, the lidar module is mounted on the top of the body through the universal joint, and the installation position of the lidar module can be finely adjusted through the universal joint.

[0014] For example, in one embodiment of the highway warning device, an on-board charging port, a power conversion module and a rechargeable lithium battery are provided inside the body to provide power.

[0015] For example, in one embodiment of the highway early warning device, casters are provided at the bottom of the body, handles are provided on the side of the body, and a handle is provided on the rear surface of the body to facilitate the movement of the intelligent early warning robot.

[0016] The beneficial effects of the highway early warning device provided in some embodiments of this application are as follows: Based on the current road construction safety warnings, this application adds a more direct and effective forward early warning device for on-site construction personnel at the front end of the traffic control area. It has functions such as warning sign display, audio broadcast, video monitoring and recording before and after the construction section, flashing warning, and fog light warning. At the same time, it can also detect vehicles that have mistakenly entered the traffic control area, realizing the purpose of moving from passive warning to active prevention. The intelligent early warning robot of this application can be remotely linked with the matching intelligent early warning vest to achieve effects such as vibration, buzzing, and flashing lights. The intelligent early warning vest can not only passively reflect light but also actively emit light, further improving the vigilance of construction personnel, extending the avoidance distance of danger, and buying valuable time for safe evacuation. On-site, it can provide forward warning and early avoidance, thereby reducing the harm to the lives of construction personnel from passing vehicles and reducing the occurrence of accidents. At the same time, it can more intuitively realize real-time inspection and supervision of on-site construction conditions and safety guidance through remote monitoring and intercom, improving the efficiency of on-site safety management.

[0024] This application provides a highway early warning device, such as... Figure 1-4 As shown, the system includes an intelligent early warning robot 100 and an intelligent early warning vest 200. The intelligent early warning robot 100 is used to detect vehicles or people accidentally entering the construction site. It includes a main controller 110 and a camera module 120, a lidar module 130, and an audible and visual alarm component 140 electrically connected to the main controller 110. The camera module 120 includes a front-facing camera 121 for monitoring road conditions in the direction of oncoming vehicles at the construction site and a rear-facing pan-tilt camera 122 for monitoring the construction situation. The lidar module 130 is used to detect vehicles or people accidentally entering the construction site within its range. The intelligent early warning vest 200 is worn by construction personnel and is equipped with a vest alarm component 210. The intelligent early warning vest 200 is communicatively connected to the intelligent early warning robot 100 and is linked with the audible and visual alarm component 140 of the intelligent early warning robot 100 to issue an early warning.

[0025] The intelligent early warning robot 100 of this application is placed at the front end of the traffic control area, providing on-site construction personnel with a more direct and effective forward early warning device. The effective range of radar monitoring is adjusted by the knob on the main controller 110, and data is collected from the lidar module 130. When a person or vehicle that has mistakenly entered the area is detected within the effective range, a signal is sent to the construction personnel wearing the intelligent early warning vest 200 to remind them that a person or vehicle has mistakenly entered the area, thereby increasing the avoidance distance and buying valuable time for safe evacuation. This enables on-site early warning and advance avoidance, thereby reducing the harm to the lives of construction personnel from passing vehicles and reducing the occurrence of accidents.

[0026] The working range of the lidar module 130 can reach 150-200m, which means it can detect vehicles that mistakenly enter within a range of 150-200 meters. The lidar module 130 is linked with the smart warning vest 200 through LoRa wireless communication.

[0027] The front and rear cameras of this application have real-time video monitoring, remote supervision of construction, and recording functions. They can be used for remote monitoring and intercom to achieve more intuitive real-time inspection and supervision of on-site construction and safety guidance, thereby improving the efficiency of on-site safety management.

[0028] For example, in one embodiment of the highway warning device, such as Figure 1-2 As shown, a communication antenna 150 is provided on the intelligent early warning robot 100, and a receiving antenna 220 is provided on the intelligent early warning vest 200 to receive control signals sent by the intelligent early warning robot 100.

[0029] Specifically, the communication antenna 150 adopts LoRa wireless spread spectrum communication, which can meet a maximum communication distance of 3km under good environmental conditions. The spread spectrum modulation technology of wireless devices has advantages such as ultra-long distance transmission and strong anti-interference ability, and is suitable for equipment that operates stably for a long time or remote monitoring equipment. 433MHz is selected as the frequency band for data transmission, the transmission and reception channels are the same, the transmission mode is the same, and the transmission power is set to the maximum power of 22dBm.

[0030] For example, in one embodiment of the highway warning device, such as Figure 1-2 As shown, the sound and light alarm component 140 includes a fog light 141, a voice broadcast system 142, a strobe light 143, and a display module 144, so as to provide sound, light and text display warnings when the lidar module 130 detects that there are vehicles or people who have mistakenly entered within the range in front of the construction position.

[0031] The main controller 110 is responsible for the linkage control of fog lights 141, strobe lights 143, lidar module 130, display module 144, voice broadcast system 142 and wireless communication devices.

[0032] Specifically, the display module 144 is a P5 display module that supports user customization. Before use, users can enter relevant prompts on a PC according to their needs. Personalized reminder content can be set according to different scenarios and needs. The display module 144 has a display screen 1441, which is located in the center area of ​​the front surface 161 of the body 160, thereby realizing text warning reminders.

[0033] Fog lights 141 are located on either side of the display screen 1441. The synchronized flashing cycle of the two fog lights 141 can be set to 1.5 seconds, with each light illuminating for 1 second. The synchronized left and right fog lights 141 provide good illumination and warning in low visibility conditions. The fog lights 141 utilize pure yellow LEDs, are unaffected by rain or fog, are dustproof and fogproof, have a long lifespan, low power consumption, high brightness, low light decay, and feature built-in reflectors for long range and wide coverage. Operating temperature: -40℃~+105℃, waterproof rating: IP67.

[0034] The voice broadcast system 142 can be equipped with a 100W high-decibel speaker to provide clear voice prompts, reminding oncoming vehicles to avoid construction areas and drive safely. It is also equipped with a knob for volume adjustment.

[0035] Two sets of strobe lights enhance the visual warning effect, alerting surrounding personnel and vehicles to the presence of road construction. The strobe lights are available in high-brightness, non-glaring, waterproof and dustproof versions, each with 24 LED beads, red / blue strobe modes, and an ABS lens housing.

[0036] For example, in one embodiment of the highway warning device, such as Figure 3-4 As shown, the vest alarm component 210 includes a waterproof buzzer 211, a waterproof vibration module 212, and a light 213, so as to simultaneously emit sound, light, and vibration warning information after the smart warning vest 200 receives the warning signal from the smart warning robot 100.

[0037] Specifically, after receiving the warning signal from the intelligent warning robot 100, the intelligent warning vest 200 activates the waterproof buzzer 211, the waterproof vibration module 212, and the light 213 simultaneously to remind construction workers. The intelligent warning vest 200 of this application not only has the reflective function of the original reflective vest, but also can actively emit light. The light 213 has a red light flashing function with a flashing frequency of 1 second per cycle, achieving the purpose of moving from passive warning to active prevention.

[0038] For example, in one embodiment of the highway warning device, such as Figure 3-4As shown, the smart warning vest 200 is also equipped with a wireless communication control box 230. The wireless communication control box 230 is equipped with an antenna and controls the waterproof buzzer 211, the waterproof vibration module 212 and the light 213 to turn on and off through the wireless communication control box 230.

[0039] For example, in one embodiment of the highway warning device, such as Figure 3-4 As shown, the receiving antenna 220 is a flexible antenna that matches the clothing, and a filtering circuit is provided inside the receiving antenna 220.

[0040] Among them, the receiving antenna 220 is a high-gain receiving antenna, which increases the transmission power of the intelligent early warning robot 100 by 1.5 times within the allowable range. A matching filter circuit is added inside the receiving antenna 220 to match the soft antenna inside the clothing. The gain of the receiving antenna 220 is increased to 18dBi, the return loss is best matched around 433MHz, the VSWR is ≤1.5, and the measured communication range is increased to 3km.

[0041] For example, in one embodiment of the highway warning device, such as Figure 1-2 As shown, the intelligent early warning robot 100 includes a body 160, which has a front surface 161 facing the direction of oncoming vehicles and a rear surface 162 facing the construction site. The sound and light alarm component 140 is disposed on the front surface 161 of the body 160 to warn vehicles or personnel that may accidentally enter the construction site. The camera module 120 and the lidar module 130 are disposed on the top of the body 160, with the front camera 121 and the lidar module 130 facing the front surface 161 of the body 160 and the rear camera 122 facing the rear surface 162 of the body 160.

[0042] Among them, the front camera 121 can detect the road conditions ahead, and the rear camera 122 can detect the road conditions under construction behind. The front and rear cameras can be equipped with 4-megapixel ultra-high-definition cameras, full-color intercom, 32GB memory card, 6mm focal length, wide-angle focal length, 1 / 3-inch light sensor, intelligent night vision mode, IP67 waterproof and dustproof rating, and can display two screens on the user software at the same time, including night scene, remote voice dialogue and other functions.

[0043] The LiDAR module 130 can emit a 905nm wavelength laser beam, ≤10mW; it complies with GB7247.1-2001, Class I laser eye safety requirements. Measurement accuracy is ±0.05m@50m or ±0.1m@150m, distance resolution: 1cm, 20-20kHz, operating temperature: -40℃~+85℃, operating humidity: 0%~100% RH, ambient light resistance: >100kLux.

[0044] For example, in one embodiment of the highway warning device, such as Figure 1-2 As shown, a universal joint 170 is provided on the top of the body 160. The lidar module 130 is mounted on the top of the body 160 through the universal joint 170, and the installation position of the lidar module 130 can be finely adjusted through the universal joint 170.

[0045] According to the above embodiment, since the installation location of the equipment is uncertain, a universal joint is designed according to the requirements. By setting a universal joint 170 on the top of the body 160, the size of the lidar module 130 can be finely adjusted up, down, left and right through the universal joint 170.

[0046] For example, in one embodiment of the highway warning device, such as Figure 1-2 As shown, the body 160 is equipped with a vehicle charging port 163, a power conversion module 164 and a rechargeable lithium battery 165 to provide power.

[0047] According to the above embodiments, the intelligent early warning robot 100 can be charged nearby via the vehicle-mounted charging port 163; the power conversion module 164 is a 12V to 5V power conversion module, which can ensure that each intelligent early warning robot can be used under different voltage conditions; the rechargeable lithium battery 165 is 12V 50Ah and has a power display function, which allows users to understand the battery status at any time and ensures the continuous operation of the intelligent early warning robot. It can meet the installation requirements of vehicle-mounted, floor-mounted, and railing-side-mounted intelligent early warning robots, and is convenient and flexible for deployment in different scenarios.

[0048] For example, in one embodiment of the highway warning device, such as Figure 1-2 As shown, the bottom of the body 160 is provided with casters 166, the side of the body 160 is provided with a handle 167, and the rear surface 162 of the body 160 is provided with a handle 168, so as to facilitate the movement of the intelligent early warning robot 100.

[0050] The intelligent early warning robot of this application is small in size, easy for users to move and use, and resembles a robot in appearance. It is powerful, adaptable, and has high-performance data processing capabilities, as well as good stability and scalability. The front and rear camera devices have real-time video monitoring, remote supervision of construction, and recording functions, enabling more intuitive real-time inspection, supervision, and safety guidance of on-site construction, and improving the efficiency of on-site safety management. The intelligent early warning vest provides tactile and visual alerts to safety warnings on the construction road, increasing the vigilance of construction personnel, extending the avoidance distance from danger, and buying valuable time for safe evacuation.
