Description

TECHNICAL FIELD

[0001] The present application relates to the field of expressway safety warning, in particular to an expressway work zone safety warning system and method. BACKGROUND

[0002] Highway maintenance management is an important part of expressway operation management, and is a key means to ensure the high-quality service of expressway. Because the expressway maintenance work zone adopts a closed management mode, and the expressway has large traffic flow and high speed, the safety supervision equipment in the work zone is imperfect, and the safety awareness of the staff is not in place, therefore, when the maintenance construction is carried out on the expressway, it is often affected by the double risks of the work zone inside and outside, i.e. the work zone outside vehicle intrusion and the dangerous placement of equipment and dangerous behavior of personnel inside the work zone, which increases the probability of safety accidents, so it is necessary to pay high attention to the safety problem of expressway maintenance construction.

[0003] For a long time, due to the influence of the concept of paying more attention to construction and less attention to maintenance, the maintenance construction level of expressway does not develop synchronously with the construction level, the maintenance foundation is relatively weak, and it is urgently needed to be improved comprehensively. At present, the main measures for safety prevention of maintenance construction include: 1) maintenance workers wear safety helmets, reflective vests and other warning work clothes; 2) protective facilities such as construction signs, warning signboards, construction reflective road cones, flashing lights, arrow lights, buffer anti-collision vehicles, etc. However, these measures are too single for the prompt of passing vehicles, do not achieve graded warning of risks, and do not actively remind the construction personnel. It can be seen that in the process of expressway maintenance, there are still problems such as inaccurate risk identification, untimely and unobvious information prompt, imperfect and untimely accident and induction information release, which need to be further solved. SUMMARY

[0004] In order to solve the problems in the prior art, the present application provides a device and system for risk identification and warning of expressway work zone, which solves the problems of low feasibility and incomplete risk warning of the safety warning system in the prior art.

[0005] The technical scheme adopted by the present application to solve its technical problems is:

[0006] The risk identification and graded warning of the expressway work zone outside vehicle intrusion, characterized by: sequentially performing the following steps:

[0007] S01, the engineering early warning vehicle is opened to the construction lane near the position, the tail of the vehicle is toward the oncoming direction, the vehicle head is parked toward the specific construction position, the vehicle-mounted panoramic camera and the vehicle-mounted control system are started by one key, wherein the vehicle-mounted panoramic camera photographs and splices the surrounding area of the engineering early warning vehicle to form a 360 panoramic image, the specific position of the construction is manually delimited by the staff in the 360 panoramic image, the vehicle-mounted control system automatically generates an intelligent traffic cone laying line, an intelligent traffic cone laying coordinate point, a portable pressure-sensitive deceleration strip layout coordinate, and an intelligent traffic cone integrated module installation coordinate according to the lane line and the construction type. The integrated intelligent traffic cone plans a driving path according to the laying coordinate point, automatically drives from the vehicle compartment and stops at the specified coordinate. The staff manually arranges the portable pressure-sensitive deceleration strip at the layout coordinate in the early warning lane. The vehicle-mounted panoramic camera and the intelligent traffic cone camera integrated module monitor and identify the internal personnel equipment risk of the work area.

[0008] If the early warning lane vehicle presses the first portable pressure-sensitive deceleration strip, step S02 is started. The vehicle-mounted panoramic camera immediately switches from the monitoring construction area mode to the early warning lane intruding vehicle tracking monitoring mode, generates two levels of virtual electronic fences between the first deceleration strip and the intelligent traffic cone in the work area upstream transition zone, and detects the speed of the intruding vehicle running on the first deceleration strip. The warning light mounted at the tail of the engineering early warning vehicle changes from yellow constant light to yellow stroboscopic light, and the intelligent traffic cone sign integrated module light at the second deceleration strip changes from non-light to red and blue stroboscopic light, which cooperates with the shock brought by the deceleration strip to the vehicle to wake up and warn the driver of the early warning lane intruding vehicle. This step is a warning and wake-up to the early warning lane intruding vehicle, and will not interfere with the staff in the construction area, avoiding misjudgment of the staff. If the oncoming vehicle is successfully awakened and drives away from the early warning lane in front of the second deceleration strip, the danger event is resolved, returns to the real-time early warning monitoring mode, and until the construction process is completely finished.

[0009] If the intruding vehicle presses the second portable pressure-sensitive deceleration strip, the vehicle-mounted panoramic camera detects the speed of the intruding vehicle running on the second deceleration strip. If the second recorded speed of the intruding vehicle is reduced by more than 35% compared with the first recorded speed and the vehicle speed is lower than 60km / h, step S03 is started, and the warning light changes from yellow stroboscopic light to red stroboscopic light.

[0010] If the second portable pressure deceleration strip is pressed on the vehicle, and the second recorded speed of the vehicle is reduced by less than 35% compared with the first recorded speed or the speed is higher than 60km / h, step S04 is started. The warning light changes from yellow flashing to red flashing, the intelligent traffic cone integrated horn module emits a high decibel alarm and broadcasts the "vehicle intrusion! Take precautions!" voice term. At the same time, the vehicle-mounted control system sends an early warning information to the construction area workers, the smart bracelet worn by the workers vibrates and displays the video taken by the vehicle-mounted panoramic camera in real time, and the wearable buzzer emits a ringing sound, timely reminding the workers to avoid danger.

[0011] S05, if the intelligent traffic cone is detected to be tilted, it means that the situation has gone out of control, at this time, rely on the physical energy absorption of the energy absorption bag to slow down the impact. The vehicle-mounted control system synchronously pushes the traffic accident alarm event to the remote monitoring center, and synchronously transmits the video taken by the vehicle-mounted panoramic camera to the remote monitoring center.

[0012] S06, in the maintenance operation end stage, first remove the portable pressure deceleration strip and the integrated module on the intelligent traffic cone by the workers, then start the intelligent traffic cone recovery mode by one key, so that the intelligent traffic cones automatically move to the operation vehicle one by one, and finally the operation vehicle can drive away.

[0013] The identification and early warning of the risk of equipment placement position and the risk of personnel behavior in the internal equipment placement position of the expressway operation area are characterized in that:

[0014] After the operation area is laid out, the traffic cone integrated camera module and the vehicle-mounted panoramic camera respectively take pictures from two vertical angles to monitor the construction area, identify the risk of equipment placement position and the risk of personnel behavior in the construction area, and the risk of personnel behavior includes illegal wearing, abnormal behavior and fatigue.

[0015] The identification and early warning of the risk of equipment placement position in the construction area are characterized in that:

[0016] The vehicle-mounted control system automatically generates a first, second and third virtual electronic fence at 1 meter inside, at and outside the line type of the intelligent traffic cone, according to the placement coordinates of the intelligent traffic cone. The first virtual electronic fence is inside the specific construction area, which is set as the construction area; the second virtual electronic fence is set as a first warning area; and the third virtual electronic fence is set as a second warning area. If the equipment in the construction area appears in the second virtual electronic fence, a first risk warning of equipment placement is triggered, the smart bracelet of the staff closest to the risk position vibrates and displays the text prompt of "equipment placement too close to the driving lane". If the equipment in the construction area appears in the third virtual electronic fence, a second risk warning of equipment placement is triggered, and the horn module of the intelligent traffic cone closest to the risk position plays the voice word "equipment intrusion into the driving lane". The integrated text information board module beside the construction area is switched from displaying "slow down" to "equipment intrusion into the driving lane, please slow down" and performs red stroboscopic flashing. To remind vehicles in the driving lane to avoid in time, and clearly prompt the staff in time.

[0017] The identification and early warning features of the staff's irregular wearing are as follows:

[0018] After the construction operation starts, if the integrated camera module of the intelligent traffic cone and the vehicle-mounted panoramic camera recognize that there is a worker wearing irregularly, a staff irregular wearing early warning is triggered. The irregular wearing refers to that the staff does not wear a safety helmet, does not wear a work shirt or does not wear work pants. The smart bracelet of the staff vibrates and displays the text information "please wear safety equipment correctly" for reminding.

[0019] The abnormal behavior of the staff includes: entering the driving lane, smoking and falling down.

[0020] The identification and early warning features of the staff entering the driving lane are as follows: if the monitoring system recognizes that there is a staff in the third virtual electronic fence, a staff entering the driving lane dangerous behavior early warning is triggered. The smart bracelet of the staff vibrates and displays the text information "please leave the driving lane quickly" for reminding. The integrated horn module of the intelligent traffic cone closest to the staff plays the voice word "please leave the driving lane quickly" to warn the staff. If the monitoring system recognizes that there is no staff in the third virtual electronic fence, it is determined that there is no dangerous behavior of entering the driving lane, and the staff in the first and second virtual electronic fences are tracked and monitored, and the monitoring picture is displayed on the vehicle-mounted central control screen in real time.

[0021] The recognition and early warning features of staff smoking and falling are as follows: if the monitoring device identifies that a staff member is smoking, a smoking behavior early warning is triggered, the staff member's smart bracelet vibrates and displays the text information "Please do not smoke" for reminding. If the monitoring device identifies that a staff member has fallen and does not get up within 3 seconds, a falling behavior early warning is triggered. The smart bracelets of all staff members vibrate and display the text information "A staff member has fallen"; all integrated speaker modules play the voice term "A staff member has fallen" to remind the staff in the work area and implement rescue.

[0022] The vehicle-mounted control system generates a state box for each staff member identified in the monitoring video, which is used to display the detailed information and environmental conditions of each monitored staff member. The vehicle-mounted control system calculates the fatigue degree of the staff member using various parameter data, and if the fatigue degree exceeds the set threshold, a fatigue early warning is triggered. After receiving the alarm signal, the staff member's smart bracelet vibrates and displays the text information "According to your working conditions and environment, it is detected that your fatigue level is high, please rest immediately" for reminding.

DETAILED DESCRIPTION

[0037] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0038] Reference Figure 1 A device and system for risk identification and early warning of highway work area, comprising an engineering early warning vehicle 3, a remote monitoring center 9, an integrated intelligent traffic cone 7, a portable pressure sensing deceleration strip 1, and a wearable device. The integrated module of the integrated intelligent traffic cone 7 includes a camera 8, a text sign, a stroboscopic light, and a horn. The wearable device includes a worker intelligent bracelet 6, a wearable buzzer 5, and a reflective workwear. The risk identification and early warning system takes the engineering early warning vehicle as the intelligent control center, and realizes identification of vehicle intrusion risk and issuance of early warning signals through the portable pressure sensing deceleration strip and the vehicle-mounted camera 301. At the same time, the vehicle-mounted camera and the integrated camera module of the intelligent traffic cone identify the risk of personnel and equipment in the construction area and issue early warning signals to achieve the purpose of safe construction.

[0039] The engineering early warning vehicle 3 is located at the upstream transition zone in the work area, as shown in Figure 1 , having the dual functions of automatic determination, execution and physical buffer collision of risk early warning. Referring to Figures 11-12The inside central control area of the engineering early warning vehicle 3 is equipped with a vehicle-mounted central control screen, and the vehicle-mounted control system 306 is integrated in the vehicle-mounted central control screen. The staff can operate on the vehicle-mounted central control screen in a touch manner, and can clearly obtain information in the work area from the vehicle-mounted central control screen. The vehicle-mounted control system is communicatively connected with the remote monitoring center 9, the worker intelligent bracelet 6 and the wearable buzzer 5, and can feed back the work area situation in real time. The energy absorption bag 302 is located at the tail of the engineering early warning vehicle and is fixedly installed. Even if a vehicle intrudes and cannot avoid, the energy absorption bag can effectively buffer when the engineering early warning vehicle is rear-ended. The vehicle-mounted warning light 305 is hung at the tail of the engineering early warning vehicle and is located above the energy absorption bag. The warning light can display two high-brightness colors of yellow and red and has two frequency flash functions of ordinary frequency flash and burst flash, wherein the burst flash frequency is higher than that of the ordinary frequency flash. The warning light has three working modes. The first working mode is a normal mode. In this mode, the warning light displays high-brightness yellow without frequency flash. The second working mode is a wake-up mode. In this mode, the warning light displays high-brightness yellow with ordinary frequency flash. The third working mode is an emergency mode. In this mode, the warning light displays high-brightness red with burst flash. The vehicle-mounted camera 301 is located at the top of the engineering early warning vehicle and is hidden in the vehicle compartment in a non-working state. In a working state, the vehicle-mounted camera is raised from the vehicle compartment by a lifting device and is raised to a specified height. The vehicle-mounted camera is a 360-degree panoramic camera and can shoot the scene around and splice it into a panoramic picture. When performing normal monitoring and identifying risks, the monitoring direction can be immediately switched according to the instruction of the vehicle-mounted control system, thereby improving the utilization rate of the equipment. The vehicle compartment of the engineering early warning vehicle is digitally reformed. The vehicle compartment is reformed into three layers. The first layer is a layer for placing portable pressure-sensitive deceleration strips 1, intelligent traffic cone integrated modules and other articles. The second layer and the third layer are special storage layers of integrated intelligent traffic cones. Wireless charging and magnetic attraction devices are arranged at each intelligent traffic cone storage position in the second layer and the third layer, so that the intelligent traffic cones can be powered in real time and are not easy to move and tilt in the storage state in the vehicle compartment. The second layer and the third layer are connected by a gentle slope 304, which provides a channel for the intelligent traffic cones to move. A detachable inclined ladder 303 is arranged between the first layer and the ground. Before the intelligent traffic cones are arranged, the inclined ladder is combined and placed at the outlet of the first layer channel, so that the intelligent traffic cones can move to the ground through the inclined ladder. After the work area is arranged, the inclined ladder is detached and placed in the first layer storage layer.

[0040] The remote monitoring center 9 is arranged at a fixed position away from the work site, generally a traffic police monitoring room or a remote monitoring room of a construction unit, and is provided with multiple remote computers, which can simultaneously uniformly and cooperatively monitor and manage multiple work sites, and can effectively reduce the use of manpower. The remote monitoring center and the engineering early warning vehicle 3 have communication function, and the remote computer therein is provided with a local and cloud storage module and a video display module. The remote computer can back up a large amount of data generated by monitoring and early warning, and retain for 90 days, so as to facilitate the evidence collection and tracing of responsibility after an accident.

[0041] Reference Figures 6-7 The integrated intelligent traffic cone 7 is provided with wheels 705 at the bottom. When the traffic cone is in the storage state in the engineering early warning vehicle 3 and the placing state on the road, the wheels can be lifted into the cone barrel through the lifting shaft 704, which can not only reduce the occupied space but also increase the contact area with the ground to increase the friction. The integrated intelligent traffic cone is provided with a power system 703 and a Beidou positioning module 702, which can automatically complete the placing according to the coordinates of each traffic cone point planned by the vehicle-mounted control system 306 of the engineering early warning vehicle. After the work is completed, the automatic recovery is completed according to the position coordinates of the engineering early warning vehicle. The top interface 701 of the intelligent integrated traffic cone can be provided with an integrated component.

[0042] Reference Figures 8-10 The middle cavity 106 of the portable pressure-sensitive deceleration strip 1 is a hot melt adhesive storage position. When laying, the staff uses a pressure gun to pressurize the cavity at the deceleration strip pressure hole 101, so that the hot melt adhesive flows out from the deceleration strip bottom flow guide hole 109 and is uniformly adhered between the deceleration strip and the ground through the flow guide groove 107. The middle part of the portable deceleration strip is not completely connected with the two sides of the pressure sensing detection part 102. When a vehicle passes through the deceleration strip, the two sides of the pressure sensing detection part are pressed down, and the alarm is triggered when the threshold of the pressure sensor 104 is exceeded. When the pressure is too large, the limiting block 103 can reduce the deformation of the pressure sensing detection part. The first deceleration strip is arranged at a position about 110 meters away from the engineering early warning vehicle 3 in the direction of the incoming vehicle in the early warning lane, which is the boundary of the first early warning range in the early warning lane. The second deceleration strip 1 is arranged at a position about 40 meters away from the engineering early warning vehicle in the direction of the incoming vehicle in the early warning lane, which is the boundary of the second early warning range in the early warning lane. The staff completes the laying of the two deceleration strips according to the placing position. Figure 5The first portable pressure deceleration strip has direct A signal connection with the vehicle warning light 305, the integrated sign module and the vehicle control system 306, that is, the alarm signal A sent by the internal signal transmitter of the first portable pressure deceleration strip can only be received by the signal A receiver of the vehicle warning light, the integrated sign module and the vehicle control system. The second portable pressure deceleration strip has direct B signal connection with the vehicle warning light and the vehicle control system, that is, the alarm signal B sent by the internal signal transmitter of the second portable pressure deceleration strip can only be received by the signal B receiver of the vehicle warning light and the vehicle control system. The risk identification device and the early warning device directly communicate through the signal transmitter and the signal receiver, which can reduce the alarm signal delay and improve the early warning efficiency.

[0043] The wearable device includes a worker intelligent bracelet 6, a wearable buzzer 5 and a reflective work clothes. The worker intelligent bracelet has a vibration reminding function and is in communication connection with the vehicle control system 306, so as to realize receiving and playing the video pushed by the vehicle control system to the worker intelligent bracelet. The wearable buzzer is in communication connection with the vehicle control center, so as to immediately emit a buzzing sound when receiving the alarm signal sent by the vehicle control system.

[0044] The use method steps and the early warning process of the system in actual application are as follows:

[0045] System initialization:

[0046] Firstly, the staff stops the engineering warning vehicle 3 at the front end of the specific construction area according to the specific construction position of the highway, and keeps the tail of the engineering warning vehicle facing the oncoming direction, and the process is completed by the driver manually driving the engineering warning vehicle. Then the staff opens the vehicle control system 306 in the car with one key, adjusts the height of the vehicle-mounted panoramic camera 301 on the vehicle-mounted central control screen, so that it can obtain a better viewing angle. The vehicle-mounted panoramic camera obtains image data around the engineering warning vehicle, and transmits the image data to the vehicle control system, and the program and algorithm built-in the vehicle control system analyze and identify the image data, and synthesize and splice the image data in multiple directions shot by the vehicle-mounted panoramic camera to form a 360 panoramic image centered on the engineering warning vehicle. At the same time, the 360 panoramic image is displayed to the staff through the vehicle-mounted central control screen. The staff draws the specific construction range through the vehicle-mounted central control screen, and the vehicle control system automatically determines the warning lane, the work area boundary line type and the engineering warning vehicle pre-stopping position according to the position information input by the worker. At the same time, the engineering warning vehicle automatically drives and stops at the predetermined position according to the predetermined position. The vehicle control system automatically labels the installation point coordinates of the integrated intelligent traffic cone 7 and the integrated module distribution at the work area boundary line type in the image, and at the same time, transmits the installation point coordinates to the integrated intelligent traffic cone control unit, and after data distribution, each installation point coordinate corresponds to an integrated intelligent traffic cone. The vehicle control system automatically generates the placement positions of two deceleration strips 1 in the warning lane, and the staff completes the layout of the deceleration strips according to the placement positions. The vehicle control system detects and identifies the lane line information of the warning lane through the built-in algorithm, and automatically generates two levels of virtual electronic fences 11 at the placement positions of the two deceleration strips in the warning lane. The first level of virtual electronic fence in the two levels of virtual electronic fences ranges from: the closed area composed of the two lane lines of the warning lane and the two portable pressure deceleration strips 5 meters in front of the two portable pressure deceleration strips; the closed area composed of the two lane lines of the warning lane, the portable pressure deceleration strip close to the work area 5 meters in front of the portable pressure deceleration strip and the traffic cone placement line in the transition area upstream of the work area. The vehicle-mounted panoramic camera monitors the oncoming vehicles in the warning lane and only identifies and tracks the vehicles entering the virtual electronic fence, and the oncoming vehicles outside the warning lane are not identified and tracked. The vehicle control system can detect the vehicle speed according to the real-time pictures shot by the vehicle-mounted camera.

[0047] Specifically, the installation points of the integrated intelligent traffic cone 7 are displayed in the form of coordinate numbers, each installation point corresponds to a digital coordinate, the digital coordinate is marked based on the above-mentioned 360 panoramic image, and the corresponding ground position of the road surface is distributed in combination with the Beidou positioning system, and the corresponding digital coordinate is distributed to the corresponding intelligent integrated traffic cone, and each digital coordinate corresponds to the ID of each intelligent traffic cone, completing the digitization of the placement position of the intelligent traffic cone. After the above-mentioned digital coordinate is built, the vehicle-mounted control system sends an automatic placement instruction to the integrated intelligent traffic cone, and controls the integrated intelligent traffic cone to travel to the specified digital coordinate with the engineering warning vehicle 3 as the origin. The integrated intelligent traffic cone arrangement travels according to the program setting instruction, and is arranged in a near-to-far manner. Among them, each integrated intelligent traffic cone is numbered differently, and the staff manually fixes the integrated module on the intelligent integrated traffic cone with the corresponding ID number according to the integrated module distribution. At the same time, the staff in the work area fixes the energy absorption bag 302 at the tail of the engineering warning vehicle to complete the initialization of the work area risk identification and warning system.

[0048] The identification and warning of the risk of vehicles entering the work area from the outside are characterized by:

[0049] Reference Figure 2, if the warning lane vehicle presses the first portable pressure-sensitive deceleration strip 1 laid on the ground and triggers the pressure sensor 104 built-in the deceleration strip, and the vehicle-mounted panoramic camera 301 recognizes that there is a vehicle in the first-level virtual electronic fence 11, the vehicle-mounted control system 306 determines that the vehicle has triggered the first-level warning of the work area vehicle intrusion and controls the relevant equipment to perform the first-level warning work. The distance of the first warning area is set to 110 meters, that is, the first portable pressure-sensitive deceleration strip laid in the warning lane is 110 meters away from the engineering warning vehicle 110. The portable pressure-sensitive deceleration strip is provided with a trigger threshold for the pressure sensor, and the pressure sensor will only generate a signal when the pressure exceeds the threshold. The first portable pressure-sensitive deceleration strip sends an alarm signal A to the vehicle-mounted warning light 305, the integrated signal sign module and the vehicle-mounted control system through the signal transmitter. The vehicle-mounted warning light, the integrated signal sign module and the vehicle-mounted control system are provided with a class A signal receiver specially for receiving class A alarm signals. The class A signal receiver built-in the vehicle-mounted warning light receives the alarm signal from the first portable pressure-sensitive deceleration strip, and immediately switches the vehicle-mounted warning light from the yellow constant state to the yellow ordinary frequency flashing state. The class A signal receiver built-in the integrated signal sign module receives the alarm signal from the first portable pressure-sensitive deceleration strip, and immediately switches the integrated signal sign module from the light-off state to the red-blue light alternating frequency flashing state. The class A signal receiver built-in the vehicle-mounted control system receives the alarm signal from the first portable pressure-sensitive deceleration strip, and immediately controls the vehicle-mounted panoramic camera to switch from the monitoring construction area state to the monitoring warning lane vehicle direction state. The vehicle-mounted control system detects the speed of the intruding vehicle driving on the first deceleration strip according to the monitoring video and records it. The vehicle-mounted control system and the vehicle-mounted panoramic camera transmit real-time video data through Bluetooth or 5G signals. When all the above-mentioned devices complete the work according to the instructions, the first-level warning processing scheme for the work area vehicle intrusion is completed. The scheme can stimulate the visual of the driver of the intruding vehicle in the warning lane through the change of the light frequency flashing state, and at the same time, combined with the vibration feeling of the vehicle driving through the portable pressure-sensitive deceleration strip, the driver can be awakened and warned from visual and tactile aspects to take evasive action.

[0050] If the intruding vehicle drives through the first portable pressure-sensitive deceleration strip 1 and successfully triggers the first-level warning, but the pressure sensor 104 built-in the second portable pressure-sensitive deceleration strip is not triggered, and the vehicle-mounted panoramic camera 301 detects that there is no vehicle in the virtual electronic fence 11, the vehicle-mounted control system determines that the intruding vehicle drives away from the warning lane between the two portable pressure-sensitive deceleration strips, that is, the vehicle intrusion danger is eliminated.

[0051] If the intruding vehicle drives through the first portable pressure deceleration strip 1 and successfully triggers a first level of pre-warning, the pressure sensor 104 in the second portable pressure deceleration strip is also triggered, and the vehicle-mounted panoramic camera 301 recognizes the presence of a vehicle in the second level of virtual electronic fence 11, the vehicle-mounted control system 306 determines that the vehicle has triggered the escalation of the pre-warning situation of the work area vehicle intrusion. The vehicle-mounted control system detects the speed of the intruding vehicle driving on the second deceleration strip and records it, and analyzes the two recorded vehicle speeds to determine whether the intruding vehicle has taken active deceleration avoidance behavior and the probability of danger.

[0052] The method for determining whether the vehicle has taken active deceleration avoidance behavior is: if the speed of the second time driving on the portable pressure deceleration strip 1 is reduced by more than 0.35 compared to the first time driving on the portable pressure deceleration strip (referred to as the reduction amplitude), it is determined that the vehicle driver has taken active and active deceleration avoidance behavior; if the reduction amplitude is less than 0.35, it is determined that the vehicle driver has not taken active and active deceleration avoidance behavior or that the vehicle's brake has a problem causing the vehicle's braking distance to increase. The method for determining the probability of danger is: if the speed of the vehicle driving on the second portable pressure deceleration strip 1 is greater than 60km / h, it indicates that the braking distance of the vehicle at this speed is greater than the distance between the second portable pressure deceleration strip 1 and the work area cone barrel 7, that is, it is determined that the vehicle does not meet the safety braking requirement. If the speed is less than 60km / h, it is determined that the vehicle meets the safety braking requirement. The calculation method of the reduction amplitude is: reduction amplitude = (second recorded speed - first recorded speed) / first recorded speed.

[0053] If the vehicle-mounted control system 306 analyzes that the speed reduction amplitude of the intruding vehicle is greater than 0.35 and the speed of the intruding vehicle driving on the second portable pressure deceleration strip 1 is less than 60km / h, it is determined that the intruding vehicle triggers the second level of pre-warning of the work area vehicle intrusion and controls the relevant equipment to perform the second level of pre-warning work. If the vehicle-mounted control system analyzes that the speed reduction amplitude of the intruding vehicle is less than 0.35 or the speed of the intruding vehicle driving on the second portable pressure deceleration strip is greater than 60km / h, it is determined that the intruding vehicle triggers the third level of pre-warning of the work area vehicle intrusion and controls the relevant equipment to perform the third level of pre-warning work.

[0054] The second level of pre-warning work of the work area vehicle intrusion, characterized by:

[0055] The second portable pressure deceleration strip 1 triggers the pressure sensor 104, and the portable pressure deceleration strip sends the alarm signal B to the warning light 305 and the vehicle control system 306. The warning light and the vehicle control system are built-in with a B-type signal receiver specially for receiving the B-type signal. The warning light built-in B-type signal receiver receives the alarm signal from the second portable pressure deceleration strip, and immediately switches the pre-warning light from the yellow ordinary frequency flashing state to the red burst flashing state. The vehicle control system built-in B-type signal receiver receives the alarm signal from the second portable pressure deceleration strip 1, and the vehicle control system determines the speed of the intruding vehicle recorded twice. The determination result is that the vehicle intrudes the second level pre-warning, and the vehicle control system controls the vehicle panoramic camera 301 to continue tracking the intruding vehicle. In the scheme, the vehicle control system determines that the driver of the intruding vehicle takes the initiative to actively decelerate and take risk-avoiding behavior, and the second recorded speed meets the braking requirement. Therefore, only the intruding vehicle is reminded in terms of visual and tactile in the aspects of light frequency flashing and deceleration strip vibration, and the working personnel in the construction area are not pre-warned, so as to reduce the psychological pressure of the working personnel.

[0056] The working area vehicle intrusion three-level pre-warning work is characterized in that:

[0057] The second portable pressure deceleration strip 1 triggers the pressure sensor 104, and the portable pressure deceleration strip sends an alarm signal B to the warning light 305 and the vehicle-mounted control center 306. The warning light is immediately switched from a yellow general frequency flashing state to a red burst flashing state. The vehicle-mounted control system determines the vehicle speed recorded twice by the intruding vehicle, and the determination result is that the vehicle intrudes into the three-level warning, and immediately sends an alarm signal to the integrated horn module, the wearable buzzer 5, the worker intelligent bracelet 6 and the remote monitoring center 9 in the entire work area. After the integrated horn module receives the alarm signal from the vehicle-mounted control system, it immediately emits a high-decibel alarm sound and broadcasts the voice term "vehicle intrusion! Take precautions!". After the wearable buzzer receives the alarm signal from the vehicle-mounted control system, it immediately emits a buzzing sound. After the worker intelligent bracelet receives the alarm signal from the vehicle-mounted control system, it immediately vibrates and plays the image of the warning lane intruding vehicle direction taken by the vehicle-mounted panoramic camera in real time. After the remote control center receives the alarm signal from the vehicle-mounted control system, it immediately starts remote guidance and rescue work. In the scheme, the vehicle-mounted control system determines that the driver of the intruding vehicle does not take active and positive deceleration precautions or that the braking system of the intruding vehicle has problems, so the risk of work area vehicle intrusion accident is extremely high, which seriously threatens the personal safety of workers in the construction area. The scheme warns the intruding vehicle and the worker at the first time, and the intruding vehicle is reminded by light frequency flashing, deceleration strip vibration and high-decibel horn alarm in three aspects of vision, touch and hearing. The worker is reminded by intelligent bracelet vibration and high-decibel horn alarm and voice broadcast in two aspects of touch and hearing. The worker intelligent bracelet plays the image taken by the vehicle-mounted panoramic camera in real time, which can help the worker understand the state and development of the intruding vehicle in the warning lane.

[0058] The identification and warning of the risk of equipment placement and personnel behavior in the work area are characterized in that: the intelligent traffic cone integrated camera module 8 on the side of the construction area and the vehicle-mounted panoramic camera 301 monitor the construction area from two perpendicular directions.

[0059] Among them, the identification and warning of the risk of equipment placement in the construction area are characterized in that:

[0060] The vehicle-mounted control system 306 automatically generates the first-level and third-level virtual electronic fence positions of the construction area according to the specific construction area position information input by the worker, the first-level virtual electronic fence is generated by the intelligent traffic cone integrated camera module 8 on the side of the construction area according to the first-level virtual electronic fence position, the third-level virtual electronic fence is generated by the vehicle-mounted panoramic camera 301 according to the third-level virtual electronic fence position, and the second-level virtual electronic fence is generated according to the cone barrel placement line. Reference Figure 4The first virtual electronic fence is set 1 meter inside the traffic cone arrangement line and is jointly formed with the central divider boundary; the second virtual electronic fence is set at the traffic cone arrangement line and is jointly formed with one side of the first virtual electronic fence; and the third virtual electronic fence is set outside the traffic cone arrangement line and is jointly formed with the driving lane. The integrated camera module and the vehicle-mounted panoramic camera on the engineering warning vehicle are connected with the vehicle-mounted control system through 5G or Bluetooth signals, and can send the monitored pictures to the vehicle-mounted control system in real time for processing. The vehicle-mounted control system is internally provided with an image processing algorithm and a YOLO video recognition algorithm. Before the system is applied, the staff trains the construction equipment dataset in the work area by using the YOLO algorithm to ensure that the recognition has a high accuracy rate when applied. After the equipment is started, the intelligent traffic cone integrated camera module generates the first and second virtual electronic fences, and the vehicle-mounted panoramic camera generates the third virtual electronic fence. The area inside the first virtual electronic fence is defined as the construction area, the area inside the second virtual electronic fence is defined as the first warning area, and the area inside the third virtual electronic fence is defined as the second warning area. Figure 3 Figure 3 The intelligent traffic cone integrated camera module and the vehicle-mounted panoramic camera are collectively referred to as monitoring equipment. If the monitoring equipment detects that there is no construction equipment in the first and second warning areas, the vehicle-mounted control system determines that there is no risk. If the monitoring equipment identifies that there is construction equipment in the first warning area, a first-level device placement risk warning is triggered, and the vehicle-mounted control system sends an alarm signal to the staff closest to the device, and sends a prompt message to the smart bracelet of the staff. The prompt message is that the smart bracelet vibrates and displays a reminder box, and the reminder box displays "Device placement is too close to the driving lane". If the monitoring equipment cannot detect construction equipment in the first and second warning areas again, the vehicle-mounted control system determines that the risk is removed. If the monitoring equipment identifies the construction equipment in the second warning area, the vehicle-mounted control system determines that the risk is upgraded, and triggers a second-level device placement risk warning. The vehicle-mounted control system sends an alarm signal to the intelligent traffic cone integrated with a loudspeaker module and a text information board closest to the device, so that the traffic cone broadcasts voice text, and the text information board displays "Device intrusion into the driving lane, please slow down" facing the oncoming vehicles and performs red stroboscopic flashing. The scheme classifies and warns the device placement risk, can only remind one staff to pay attention when the construction equipment is too close to the driving lane, can further expand the organization risk under the premise of reducing resource occupation. When the device intrudes into the driving lane, it has caused great threat to the driving safety of vehicles in the driving lane. At this time, the staff inside is reminded by voice broadcast, and the vehicles in the driving lane outside are reminded visually, which can effectively reduce the probability of accidents.

[0061] The identification and warning features of the personnel behavior risk in the work area are:

[0062] The identification and early warning features of the personnel behavior risk include: staff wearing violations and staff abnormal behaviors, the staff abnormal behavior features include entering the driving lane, smoking and falling down behaviors. The image processing algorithm and YOLO video recognition algorithm built in the vehicle-mounted control system 306, before the system is deployed, the staff uses the YOLO algorithm for dataset training, the dataset includes work clothes and safety helmet wearing dataset, smoking dataset and falling dataset. The improved features of the safety helmet wearing recognition algorithm are: introducing spatial weights in the loss function of the YOLO algorithm, giving greater weights to the error of the head prediction area in the image, to strengthen the learning and recognition accuracy of the model to the safety helmet existing area. The prior knowledge such as the shape and position of the head is integrated, and the model's ability to distinguish safety helmets from heads is enhanced by setting rules. The improved features of the work clothes wearing recognition algorithm are: designing a feature fusion network to integrate local features such as texture and color of work clothes and global features such as human posture and relative position, to enhance the accuracy and robustness of recognition. In the training process, multi-scale input is applied, so that the model can better adapt to input images of different resolutions, thereby improving the generalization ability of work clothes recognition. The improved features of the small target detection recognition algorithm for smoking behavior are: using long short-term memory network (LSTM) or three-dimensional convolution network (3D CNN) to analyze time series video data, especially the continuity of hand movement small actions, to accurately detect smoking behavior. In the YOLO network, high-resolution hand image areas are trained to improve the detection accuracy of small cigarette targets. The improved features of the personnel falling recognition algorithm are: combining dynamic image processing technology and static posture recognition technology to analyze the speed and acceleration of human motion to identify the characteristic actions of falling. The improved features of the detection speed of the recognition algorithm are: applying network pruning and knowledge distillation techniques to simplify the network structure without sacrificing performance, reducing computational complexity and improving inference speed. Using a dedicated deep learning accelerator (such as NVIDIA's TensorRT), the model is optimized to run on specific hardware, thereby improving processing speed.

[0063] The identification and early warning features of the staff wearing violations in the work area are:

[0064] After the equipment is deployed, the monitoring equipment detects the wearing standard of the staff in the work area. If the monitoring equipment identifies that the staff does not wear a safety helmet, does not wear a work shirt or does not wear work pants, the vehicle-mounted control system 306 determines to trigger the staff wearing early warning, and sends an alarm signal to the smart bracelet 6 of the staff through a 5G or Bluetooth signal. After receiving the alarm signal, the smart bracelet vibrates and displays the text information "please wear safety equipment correctly" to remind.

[0065] The identification and early warning feature of the worker breaking into the driving lane in the work area is characterized in that:

[0066] The vehicle-mounted control system 306 identifies whether the worker breaks into the driving lane by using the secondary virtual electronic fence generated by the equipment placement risk identification. If the monitoring device identifies that there is no worker outside the secondary virtual electronic fence, the vehicle-mounted control system determines that there is no dangerous behavior of breaking into the driving lane, and at the same time, the worker in the secondary virtual electronic fence is tracked and monitored, and the monitored video screen is displayed on the vehicle-mounted central control screen. If the monitoring device identifies that there is a worker outside the secondary virtual electronic fence, the vehicle-mounted control system determines that there is a dangerous behavior of the worker breaking into the driving lane, and triggers the dangerous behavior of breaking into the driving lane early warning. The vehicle-mounted control system sends an alarm signal to the smart bracelet 6 of the worker and the smart traffic cone integrated horn module closest to the worker. After the smart bracelet receives the alarm signal, it vibrates and displays the text information "please quickly leave the driving lane" to remind the worker, and the integrated horn module receives the alarm signal and plays the voice word "please quickly leave the driving lane" to warn the worker. The monitoring device tracks and identifies the worker, and if it identifies that the worker enters the secondary virtual electronic fence, the vehicle-mounted control system determines that the danger is eliminated and the early warning is ended.

[0067] The identification and early warning feature of the worker smoking and falling in the work area is characterized in that:

[0068] The monitoring device monitors the behavior of the worker in the work area. If it identifies that a worker is smoking, the vehicle-mounted control system 306 determines to trigger the smoking behavior early warning, and sends an alarm signal to the smart bracelet 6 of the worker through 5G or Bluetooth signal. After the smart bracelet receives the alarm signal, it vibrates and displays the text information "please do not smoke" to remind the worker. If the monitoring device identifies that a worker has fallen and remains in a fallen state for 3 seconds or more, the vehicle-mounted control system determines to trigger the falling behavior early warning, and sends an alarm signal to the smart bracelet of all workers in the work area and the smart traffic cone integrated horn module in the work area. After the smart bracelet receives the alarm signal, it vibrates and displays the text information "a worker has fallen" to remind the worker, and the integrated horn module receives the alarm signal and plays the voice word "a worker has fallen" to remind the worker. This scheme can monitor the worker's illegal wear and abnormal behavior in real time, respond to danger in the first time, remind and seek help in time when the worker is working alone, and improve the safety of the work area of the expressway.

[0069] The vehicle-mounted control system 306 generates a status box for each worker identified in the monitoring video, for displaying detailed information and environmental conditions of each monitored worker. The status box will display real-time air temperature, noise level, light intensity, working time, violation times, work type, etc. The vehicle-mounted control system calculates the worker's fatigue degree using the above parameter data, and if the fatigue degree exceeds the set threshold, it provides a rest reminder function through the smart bracelet 6. The air temperature, noise level and light intensity are obtained through the meteorological sensor 307 integrated on the roof of the engineering warning vehicle. The working time is timed from the moment the worker starts work. The violation times record all violations of the worker during work, such as not wearing safety equipment correctly, entering the driving lane, etc. The work type refers to the specific responsibilities of the worker, such as signal operator, construction laborer, etc. The monitoring device and the meteorological sensor collect environmental data and worker behavior information in real time, and send the information to the vehicle-mounted control system, which calculates the worker's fatigue degree according to the built-in calculation formula. The calculation formula is characterized by: F = (C t × T + C h × H + C r × R + C w × W + C n × N + C l × L) α Wherein: F: fatigue index T: working time, in hours H: absolute value of air temperature above or below the comfortable level (such as 25℃) R: violation times W: physical requirement index of work type (light, medium, heavy), respectively defined as 1, 2, 3 N: environmental noise level (dB), exceeding the normal level (such as 85dB) L: environmental light intensity variation, deviation from ideal light intensity C t ,C h ,C r ,C w ,C n ,C l : weight of each factor, value based on occupational health research and field test data. α: nonlinear index, used to amplify or reduce the sensitivity of the calculation result, value is 1.3

[0070] The vehicle-mounted control system 306 calculates the fatigue degree F according to the parameter values, judges whether it exceeds the set threshold, and triggers the fatigue warning if it exceeds the set threshold. The vehicle-mounted control system sends the warning signal to the smart bracelet 6 of the worker through a 5G or Bluetooth signal. After receiving the alarm signal, the smart bracelet vibrates and displays the text information "According to your working conditions and environment, it is detected that your fatigue level is high. Please rest immediately" for reminding. This scheme monitors the fatigue state of the worker in real time. The system can warn before the fatigue level reaches the dangerous threshold, thereby preventing accidents caused by excessive fatigue. This directly reduces the incidence of work accidents and improves the overall safety of the highway operation area.
