[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The present invention will be described in further detail below.
[0031] This invention discloses a safety management and control system for highway maintenance work areas. It includes a cloud platform, smart traffic cones, flashing warning devices, wearable devices for maintenance personnel, a status detector for construction warning signs, a vehicle intrusion alarm for the construction area, and a satellite base station. The cloud platform is used to communicate in real time with the smart traffic cones, flashing warning devices, wearable devices for maintenance personnel, status detectors for construction warning signs, vehicle intrusion alarms for the construction area, the satellite base station, and vehicle navigation terminals via 5G wireless transmission equipment, processing and analyzing various data, and issuing safety warning information. The smart traffic cones have built-in positioning, monitoring, warning, power, and control modules, used to delineate the maintenance work area. The satellite base station is deployed at a high point on the construction site, providing centimeter-level positioning references and synchronously correcting the coordinates of various devices. The satellite base station can provide sub-meter or even millimeter-level positioning accuracy, accurately marking the boundaries of the work area with an error range far smaller than traditional IoT positioning. Furthermore, the satellite base station is unaffected by terrain or weather, and can still provide stable signals, especially in remote mountainous areas, tunnels, bridges, and other communication blind spots, solving the problem of significantly increased accident risks.
[0032] It also includes a tethered drone system equipped with lidar, multispectral cameras, lighting systems, and audible and visual alarms to monitor the tilt angle of smart traffic cones and the health status of maintenance personnel. The tethered drone system communicates with the cloud platform in real time and is powered 24 hours a day via a tethered cable.
[0033] The construction warning sign status detector is used to monitor the installation status of each warning sign in the work area in real time. The status detector is installed in a waterproof box on the sign mounting pole. The status detector contains a six-axis attitude sensor and a LORA wireless communication module. The six-axis attitude sensor is used to monitor the tilt angle and rotation angle of the sign in real time. When either of the above two angles exceeds the preset value, the LORA wireless communication module immediately sends an alarm to the cloud platform. The cloud platform then sends a prompt to the on-site inspection personnel to remind them to check the status of the sign in order to avoid accidents caused by the sign tilting or rotating and encroaching on the driving lane.
[0034] The construction area vehicle intrusion alarm is used to detect and monitor in real time whether external vehicles have entered the construction area, causing personal injury or property damage. The construction area vehicle intrusion alarm uses laser, radar, and infrared methods to detect whether vehicles have entered the construction area. It is deployed on the warning cone guide section upstream of the construction work area. The construction area vehicle intrusion alarm connects to the cloud platform wirelessly via LoRa, 4G, and 5G. Once the construction area vehicle intrusion alarm detects a vehicle entering the work area, it immediately reports the alarm information to the cloud platform wirelessly. After receiving the alarm, the cloud platform immediately sends an alert to all smart wearable devices on the construction site, reminding personnel to immediately evacuate to a safe area.
[0035] It also includes an electronic display device to indicate the approaching work area and to communicate with the cloud platform in real time; a monitoring module including a six-axis attitude sensor and a pressure sensor installed inside the smart cone. The six-axis attitude sensor is used to monitor the cone's tilt angle in real time, and the pressure sensor is used to detect the contact pressure between the cone and the ground in real time; a flashing warning device is equipped with a display screen, a flashlight, a laser warning light, and a loudspeaker; the maintenance personnel's wearable equipment includes a shoulder light and a safety helmet. The shoulder light contains a positioning module, a monitoring module, an intelligent warning module, a power module, and a control module, supporting a multi-level warning mode triggered by vibration. The safety helmet integrates a positioning chip, an inertial measurement unit, and a real-time video capture and transmission unit; when the smart cone falls over, maintenance personnel approach the edge of the work area, maintenance personnel fall, or maintenance personnel approach construction equipment, the shoulder light, safety helmet, and smart cone can all send warnings to the cloud platform and communicate with the vehicle navigation terminal in real time through the cloud platform, reminding personnel to immediately move to a safe area.

The water outlet pipe passes through a water pump. The water pump and the motor 61 are both controlled by a control switch. When the water pump is started, the water in the water tank enters the water spray pipe 32 through the water outlet pipe and is sprayed onto the display screen 11 through the nozzles to clean the stubborn stains on the display screen 11. At the same time, the cleaning shaft 21 drives the scraper 31 to move. The scraper 31 scrapes away the water and stains on the display screen 11, making the display screen 11 cleaner.

After the cleaning plate 22 has finished cleaning the display screen 11, the transmission mechanism 4 drives the linkage shaft 24 to rotate. The linkage shaft 24 drives the linkage gear 241 to rotate. The linkage gear 241 drives the first rack 221 and the second rack 311 to move. The first rack 221 drives the cleaning plate 22 to move, and the second rack 311 drives the scraper 31 to move, so that the cleaning plate 22 separates from the display screen 11, and the scraper 31 contacts the display screen 11. At the same time, the water spray pipe 32 is opened to continue cleaning the display screen 11, avoiding large-scale mixing of water and dust.

The transmission components include a transmission plate 41 fixedly connected to the support frame 1, and multiple evenly distributed teeth 42 are rotatably mounted on the transmission plate 41. A torsion spring is sleeved on the rotating shaft installed in the teeth 42. A transmission gear 242 that can mesh with the multiple teeth 42 is fixedly connected to the linkage shaft 24. During the rotation of the cleaning rotating shaft 21, the cleaning rotating shaft 21 drives the mounting plate 23 to rotate, and the mounting plate 23 drives the linkage shaft 24 to rotate. When the cleaning plate 22 rotates from one side of the support frame 1 to the other side, the linkage shaft 24 drives the transmission gear 242 to mesh with the multiple teeth 42. The multiple teeth 42 drive the transmission gear 242 to rotate, and the transmission gear 242 drives the linkage shaft 24 to rotate. The linkage shaft 24 drives the linkage gear 241 to rotate, thereby separating the cleaning plate 22 from the display screen 11 and making the scraper 31 contact the display screen 11.
[0042] Reference Figure 6 and Figure 7The sealing mechanism 5 includes a sealing plate 51 rotatably installed in the water spray pipe 32.

A magnet 53 is fixedly connected to the spiral rod 52. Iron blocks 54 are fixedly connected to two adjacent sides of the support frame 1. The magnet 53 can abut against the iron blocks 54. When the cleaning plate 22 rotates from one side of the support frame 1 to the other side, the magnet 53 attracts the iron blocks 54, the scraper 31 moves, the scraper 31 drives the water spray pipe 32 to move, and the water spray pipe 32 drives the sealing plate 51 to move. Since the spiral rod 52 is spirally connected to the sealing plate 51, the sealing plate 51 rotates at the same time, and the water spray pipe 32 can be opened.

When the cleaning plate 22 rotates from one side of the support frame 1 to the other side, the linkage shaft 24 drives the transmission gear 242 and multiple teeth. 42 meshes, and multiple teeth 42 drive the transmission gear 242 to rotate. The transmission gear 242 drives the linkage shaft 24 to rotate. The linkage shaft 24 drives the first rack 221 and the second rack 311 to move, causing the cleaning plate 22 to separate from the display screen 11.
