Description

Technical Field

[0001] The present invention relates to the technical field of millimeter wave radar early warning systems, and in particular to a traffic construction safety early warning device based on millimeter wave radar. Background Art

[0002] With the rapid development of urban transportation infrastructure, road construction and maintenance have become crucial for ensuring the long-term, stable operation of roads. However, during construction, factors such as heavy vehicle traffic, high speeds, and limited space in construction areas present significant traffic safety risks. This is particularly true at night or in low-visibility environments, where the risk of accidents increases significantly. Existing technologies typically use traffic cones, reflective signs, and flashing lights to warn drivers in construction areas. However, these methods rely on visual recognition and suffer from limited warning ranges, delayed responses, and ineffective warnings. They are unable to achieve real-time monitoring of oncoming vehicles and graded warnings.

[0003] An existing Chinese patent application, CN114664051B, discloses a method for warning temporary construction zones on curved highways. This method uses millimeter-wave radar to monitor vehicle driving information and promptly warns drivers when a vehicle is likely to enter a curved construction zone, thereby reducing the probability of traffic accidents caused by vehicles entering the construction zone. However, the device can only drive away intruding vehicles and lacks the ability to link vehicle path prediction with hazard warnings.

[0004] Therefore, there is an urgent need for an intelligent traffic construction safety warning device that can realize multi-level warning, real-time tracking, regional linkage control, and provide effective risk avoidance prompts to construction workers, so as to further improve the level of traffic safety protection at the construction site.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 The present invention provides a technical solution: a traffic construction safety warning device based on millimeter wave radar, including a base 1 and an operating terminal, wherein an electric drive wheel 2 is fixedly connected to the lower side of the base 1, a fixed box 3 is rotatably connected to the upper side of the base 1 through a bearing, a counterweight box 6 is fixedly connected to the left side of the fixed box 3, a master control module 4 is provided on the upper side of the fixed box 3, and a moving mechanism 5 is also provided on the upper part of the fixed box 3, the electric drive wheel 2 is electrically connected to the master control module 4, and the master control module 4 is electrically connected to the operating terminal, the electric drive wheel 2 can rotate horizontally relative to the base 1, and the electric drive wheel 2 can drive the base 1 to move, and a slide groove is provided on the fixed box 3;

[0029] The moving mechanism 5 includes a movable cross bar 507, which is located inside the upper slide groove of the fixed box 3. The outer wall of the cross bar 507 is slidably connected to the inner wall of the upper slide groove of the fixed box 3. The cross bar 507 can translate relative to the fixed box 3, and the fixed box 3 can rotate relative to the base 1. A detection mechanism 508 is provided on one side of the cross bar 507. The moving mechanism 5 also includes a first motor 501, which is located on the lower side of the fixed box 3. The output end of the first motor 501 extends to the lower outside of the fixed box 3. The output end of the first motor 501 is fixedly connected to the bevel gear 502, and the upper surface of the base 1 is fixedly connected to the gear ring 503. The outer wall of the bevel gear 502 is connected to the outer wall of the gear ring 503. The upper side of the fixed box 3 is also fixedly connected to the second motor 504, and the output end of the second motor 504 is fixedly connected to the rotating rod 505. The outer wall of the rotating rod 505 is rotatably connected to the upper side of the fixed box 3 through a bearing. The outer wall of the rotating rod 505 is fixedly connected to the first gear 506. The upper side of the cross bar 507 is provided with a transmission tooth. The lower side of the first gear 506 is engaged with the transmission tooth on the upper side of the outer wall of the cross bar 507. The first motor 501 and the second motor 504 are both electrically connected to the main control module 4, and the second motor 504 can drive the cross bar 507 to translate relative to the base 1 through the rotating rod 505 and the first gear 506. The counterweight box 6 is located on the side of the fixed box 3 away from the detection mechanism 508;

[0030] When the present device is actually used, the operator needs to control the device through the operation terminal and place a counterweight inside the counterweight box 6 for counterweighting. The operation terminal drives the electric drive wheel 2 to drive the present device to move through the master control module 4. Then, when the traffic flow is light, multiple devices can be deployed to the preset construction warning area, forming a horizontal long-distance warning area along the side close to the road shoulder. At the same time, the first motor 501 can be controlled to drive the bevel gear 502 to rotate, so that the bevel gear 502 drives the fixed box 3 to rotate relative to the base 1 due to the meshing relationship with the first motor 501. Then, after the present device moves to the preset point, the fixed box 3 is rotated to make the detection mechanism 508 face the area to be inspected, thereby avoiding people entering the traffic flow to manually adjust the device, thereby improving safety.

[0031] The detection mechanism 508 includes a data conversion module 803 and a millimeter-wave radar monitoring module 804. The millimeter-wave radar monitoring module 804 is electrically connected to the data conversion module 803, and the data conversion module 803 is electrically connected to the master control module 4. The millimeter-wave radar monitoring module 804 is used to set a preset detection area. The detection mechanism 508 also includes a column 801. A dynamic prompt mechanism 802 is provided in the middle part of the side of the column 801. The lower end of the column 801 is fixedly connected to the outer wall of one end of the crossbar 507, and the upper end of the column 801 is fixedly connected to the lower side of the data conversion module 803. The millimeter-wave radar monitoring module 804 is arranged on the front side of the data conversion module 803. A laser ranging module 805 is also provided on the front side of the data conversion module 803. The laser ranging module 805 is electrically connected to the data conversion module 803.

[0032] The detection mechanism 508 includes a data conversion module 803 and a millimeter-wave radar monitoring module 804, wherein the millimeter-wave radar monitoring module 804 is used to set and scan a preset detection area, and the detection data is transmitted to the main control module 4 via the data conversion module 803. This device can be deployed at multiple points in long distance, medium distance, and short distance according to the construction situation, with one, three, and one device deployed respectively to achieve segmented early warning. The millimeter-wave radar monitoring module 804 detects the preset area, and the data conversion module 803 transmits the detection results of the millimeter-wave radar monitoring module 804 to the main control module 4, which determines whether to trigger an alarm. At a long distance, after the device breaks into a vehicle, the data conversion module 803 transmits a signal to the main control module 4, and the main control module 4 emits a beep through the operation terminal. At a medium distance, when the device continuously monitors the passing of a vehicle through the millimeter-wave radar monitoring module 804, the operation terminal is triggered to emit a continuous beep. At a close distance, after the device detects the intrusion of a vehicle through the millimeter-wave radar monitoring module 804, the beep and vibration feedback of the operation terminal are immediately activated, thereby prompting the staff to quickly avoid it.

[0033] After a vehicle breaks into the detection area of this device placed at a long distance, the laser ranging module 805 can detect the longitudinal distance between the vehicle and this device, and transmit the distance between the front and rear of the vehicle to the main control module 4 for recording after processing by the data conversion module 803, and synchronize this data with this device at the next position through the main control module 4. When this device at the next distance detects that a vehicle has passed, the longitudinal distance between the head and rear of the vehicle and this device is also recorded by the laser ranging module 805. The longitudinal distance of the lane occupied in the construction area can be preset as a threshold. When the three laser ranging modules 805 detect that the change in the distance between the vehicle and this device does not exceed the threshold, the alarm of the operation terminal directly jumps to vibration and buzzing, and this operation has the highest priority. When the change in the longitudinal distance between the vehicle and this device exceeds the threshold, the operation terminal returns to silent state.

[0034] The dynamic prompt mechanism 802 includes a fixing ring 201, the inner wall of the fixing ring 201 is fixedly connected to the outer wall of the column 801, one side of the fixing ring 201 is rotatably connected to the mounting plate 202 through a bearing, one end of the mounting plate 202 is fixedly connected to the lamp bead plate 203, the middle part of the column 801 is fixedly connected to the third motor 204, the output end of the third motor 204 is fixedly connected to the second gear 205, the outer wall of the mounting plate 202 is fixedly connected to the third gear 206, the lower side of the third gear 206 is meshed with the upper side of the second gear 205, the lamp bead plate 203 and the third motor 204 are both electrically connected to the master control module 4, and the third motor 204 can drive the mounting plate 202 to deflect ninety degrees through the second gear 205 and the third gear 206;

[0035] When the remote device detects a vehicle entering the area and the intruding vehicle is traveling at an excessive speed, the master control module 4 synchronizes the data with the subsequent device, causing the master control module 4 to rotate the second gear 205 via the third motor 204, raising the end of the mounting plate 202 connected to the lamp board 203 by 90 degrees. Simultaneously, the master control module 4 controls the lamp board 203 to flash red and blue repeatedly. This dynamic change in posture and the switching between static and dynamic light sources enhance the recognition of the warning prompt, thereby warning the driver to slow down and avoid the vehicle. Subsequently, when the device detects that there are no vehicles in the area, the master control module 4 restores the lamp board 203 to a static display of half red and half blue. The contrast between dynamic and static warnings enhances the visual prompt effect. Furthermore, if the device, placed close to the vehicle, detects a vehicle passing by, it can record the vehicle speed via the millimeter-wave radar monitoring module 804 and store it via the master control module 4. This, combined with the laser ranging module 805, records the time and location information. In the event of an accident, complete event data can be provided for subsequent responsibility tracing.
