Description

Technical Field

[0001] This invention relates to the field of highway early warning technology, specifically to an integrated intelligent highway early warning robot. Background Technology

[0002] During highway construction, to ensure the safety of construction workers and passing vehicles, in accordance with national standards such as the "Road Traffic Signs and Markings" (GB5768) and the "Highway Maintenance Safety Operation Procedures" (JTGH30), warning signs must be placed at least 50 meters upstream of the construction area. The distance should be adjusted according to the road speed limit, and on expressways and other rapid transit sections, it may even be extended to over 200 meters. Currently commonly used warning devices include flashing warning lights and warning signs displaying messages such as "Construction Ahead" and "Slow Down." These devices use high-frequency flashing lights or conspicuous markings to remind drivers to slow down and avoid the area, effectively reducing the risk of traffic accidents.

[0003] However, the current deployment process of early warning devices presents significant safety hazards and efficiency bottlenecks. In practical engineering applications, traditional manual deployment methods require construction workers to carry warning lights and signs weighing 15-20 kg, walking against the flow of traffic at a speed of 2-3 km / h. According to statistics from the Ministry of Transport, the traffic accident rate during highway construction is 8-12 times higher than usual, with 70% of these accidents related to temporary deployment operations. In adverse weather conditions, such as dense fog with visibility below 50 meters or heavy rainfall, manual operation not only faces problems such as device slippage and positioning errors, but also extends the time for a single complete deployment to 3-5 times that of normal conditions.

[0004] From a technical perspective, traditional early warning devices generally employ a single-function design, lacking effective communication protocols between devices. When traffic flow changes or work progress is adjusted in the construction area, on-site personnel must manually adjust the status of each device individually, making real-time updates impossible through a unified platform. For example, in a provincial highway reconstruction and expansion project, due to temporary road closures caused by heavy rain, manually adjusting the early warning devices on a 12-kilometer section took as long as 4 hours, resulting in a traffic backlog of over 30 kilometers.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0024] Example 1: As Figure 1-3 As shown, to address the current situation where early warning devices need to be manually moved backwards before highway construction, and even adjusting their status is inconvenient, this embodiment provides a robot for highway early warning. The robot includes a mobile base 1, an intermediate component 2, a display module 3, and a camera 4. The intermediate component 2 and camera 4 are both positioned above the mobile base 1, with the camera 4 located at the end of the intermediate component 2. The display module 3 is mounted above the intermediate component 2. Because the mobile base 1 has movable kinetic energy, its direction can be adjusted during movement, allowing operators to control its movement via a visual remote control. During the movement of the mobile base 1, operators can wirelessly connect the visual remote control to the camera 4 to view the road conditions ahead in real time, displaying driving guidelines to ensure safe operation. Once the mobile base 1 reaches a preset position, operators use the visual remote control to rotate the display module 4 around its central axis, adjusting its orientation so that the display surface faces the vehicle, allowing passing drivers to anticipate the road conditions ahead. Display module 4 can be a full-color module, which can be fixed or scrolling, with vibrant font colors and clear information delivery, effectively improving the early warning effect. In construction areas, it can display warning slogans such as "Construction ahead, slow down"; at emergency rescue sites, it can display accident information to guide vehicles to pass in an orderly manner.

[0025] like Figure 4 , Figure 5 As shown, in order to adjust the position of the display module 3 by moving the movable base 1, the movable base 1 includes a top shell 11, a frame 12, a battery pack 15, two drive wheels 13, two steering wheels 14, etc.

[0026] like Figure 4As shown, the top shell 11 is set on the top of the frame 12 and covers the frame 12, thereby shielding the battery pack 15, motor and other devices located inside the frame 12 and improving the aesthetics of the robot.

[0027] like Figure 4 As shown, two steering wheels 14 are located at the two corners of one end of the frame 12, and two drive wheels 13 are located at the two corners of the other end of the frame 12. Thus, the frame 12 is stably supported by the steering wheels 14 and the drive wheels 13, and the frame 12 is facilitated to move.

[0028] like Figure 6 , Figure 7 As shown, the aforementioned steering wheel 14 directly adopts a publicly available swivel wheel, with appropriate improvements. Specifically, the steering shaft length of the existing swivel wheel is extended, and a top plate 141 is added to the top of the swivel wheel bracket. The function of adding the top plate 141 is to facilitate the stable installation of the top plate 141 under the fixing plate 125 under the action of bolts, and the fixing plate 125 is stably installed on the frame 12, so that the improved swivel wheel can be stably installed at the frame 12, and the orientation of the swivel wheel can be adjusted when the steering shaft is subjected to external force.

[0029] like Figure 7 As shown, to adjust the orientation of the steering wheels 14, a second worm gear 142 is fitted onto the steering shaft of each of the two steering wheels 14. A second worm 143 is meshed on the side of each second worm gear 142. A second drive shaft 144 connects the two second worms 143. A second driven gear 145 mounted on the second drive shaft 144 meshes with a second drive gear, which is mounted on the power output shaft of the second motor 146. When the second motor 146 is working, the two second worm gears 142 can be driven to rotate synchronously and in the same direction via the second drive shaft 144, forcing the steering shaft to rotate the wheels and thus adjusting the orientation.

[0030] like Figure 6 , Figure 7 As shown, in order to stably install the second worm gear 143 and the second drive shaft 144 on the frame 12, bearing seats are fitted at the ends of the two second worm gears 143 that are far apart from each other. The fixing plate 125, the bearing seats and the second motor 146 are all installed on the frame 12.

[0031] like Figure 6 , Figure 8As shown, in order to force the frame 12 to move, a first transmission shaft is connected between the central shafts of the two drive wheels 13. A first driven gear 131 mounted on the first transmission shaft is laterally engaged with a first drive gear, which is mounted on the power output shaft of the first motor 132. Bearing seats mounted on the central shafts of the drive wheels 13 are mounted on a mounting bracket 122. Both the mounting bracket 122 and the first motor 132 are mounted on the frame 12. With the first motor 132 stably installed, its operation can control the first transmission shaft to drive the two drive wheels 13 to rotate, thereby forcing the frame 12 to move.

[0032] like Figure 8 , Figure 9 As shown, in order to achieve braking of the robot after the frame 12 moves to the corresponding position, a brake plate 133 is provided on the side of the first driven gear 131 or the first driving gear. A sliding groove 134 and a sliding plate 124 are respectively provided on the sidewalls of the brake plate 133 and the frame 12, respectively. The sliding plate 124 passes through the sliding groove 134, allowing the brake plate 133 to be stably mounted on the frame 12 and providing support for its movement. To control the movement of the brake plate 133 and thus achieve braking of the robot, the brake plate 133 is installed at the extension end of the electric cylinder 135, which is mounted on the frame 12 via a bracket 123. Therefore, when the electric cylinder 135 extends, the brake plate 133 moves to the side of the first driven gear 131 or the first driving gear and engages with it. Since the brake plate 133 can only move along the length of the first transmission shaft, braking of the first driven gear 131 or the first driving gear can be achieved.

[0033] like Figure 5 , Figure 6 As shown, the battery pack 15 is mounted on the support frame 121, which is fixedly mounted on the frame 12. Therefore, the battery pack 15 is stably mounted on the bottom of the robot, and its own weight lowers the robot's center of gravity, improving its stability. Simultaneously, the battery pack 15 provides power to the display module 3 and the motors. The battery pack 15 is a rechargeable lithium-ion battery or lead-acid battery, and is equipped with a charger, charging interface, charging protection circuit, discharging protection circuit, battery management system, load drive circuit, etc., providing support for the charging and discharging of the battery pack 15.

[0034] like Figure 10As shown, in order to enable broadcasting alerts as needed, the middleware 2 includes a main housing 21, a secondary housing 22, an electronic control device 211, and a speaker 213. The top of the main housing 21 is open, and the secondary housing 22 is detachably installed at the opening on the top of the main housing 21. The electronic control device 211 and the speaker 213 are both located inside the main housing 21, with the electronic control device 211 located at the bottom of the main housing 21 and the speaker 213 installed on the side wall of the main housing 21.

[0035] To enable remote communication with the remote controller and control the operation of motors, electric cylinders, horns, display modules, etc., the electronic control device 211 includes at least a main control and logic control module, a wireless communication module, an actuator drive module, and a camera interface. The aforementioned motor can be configured as a servo motor, stepper motor, etc.

[0036] The main control and logic control module includes a microcontroller (MCU / microcontroller) and signal conditioning circuits. The MCU / microcontroller acts as the "brain" of the electronic control system, receiving remote control signals, processing logic instructions, and outputting control signals to various execution components. The signal conditioning circuit includes operational amplifiers, RC filter circuits, and level conversion chips, amplifying, filtering, or converting remote control signals to adapt to the MCU's input requirements.

[0037] The wireless communication module includes a wireless transceiver module, an antenna, and an RF matching circuit. The wireless transceiver module enables remote data transmission with the remote control, supports bidirectional communication, receives control commands, and provides feedback on device status. The antenna and RF matching circuit includes a PCB antenna, an external antenna, and RF capacitors / inductors, enhancing the stability of wireless signal transmission and reducing interference.

[0038] The actuator drive module includes motor and cylinder drivers, horn drivers, and display module drivers. The motor and cylinder drivers include motor driver chips / drivers, relays / solid-state relays, etc.; the motor driver chip / driver amplifies the control signals output by the MCU to drive the motor / cylinder; the relays / solid-state relays control the on / off switching of high-power motors / cylinders, isolating high-voltage and low-voltage circuits. The horn driver is configured as an audio amplifier to amplify audio signals and drive the horn to produce sound. The display module driver is configured as a display driver circuit, connecting the MCU and the display screen, converting data formats, and driving pixel display.

[0039] The camera interface connects to the camera and transmits video data to the main controller, supporting image acquisition and processing.

[0040] In addition, the electronic control device 211 is connected to the circuit of the battery pack 15, thereby providing power to the motor, electric cylinder, horn and display module.

[0041] like Figure 4 , Figure 10As shown, in order to stably install the main shell 21 on the top shell 11, the top shell 11 and the main shell 21 are respectively provided with a connecting plate 111 and a connecting plate 212 facing each other on their side walls. A connecting bolt 112 is inverted and engaged in the slot 113 at the end of the connecting plate 111, that is, the connecting bolt 112 is inverted and the end of the connecting bolt 112 is installed in the slot 113. At the same time, the top of the connecting bolt 112 passes through the end of the connecting plate 212. Then, a nut is threaded on the top of the connecting bolt 112. When the nut is turned, it presses down on the connecting plate 212 and the connecting plate 111, so that the connecting plate 212 and the connecting plate 111 are stably connected, thereby making the main shell 21 stably installed.

[0042] like Figure 11 , Figure 13 As shown, to stably mount the display module 3 on the sub-shell 22, a support plate 23 is provided above the sub-shell 22. An insertion hole 234 and an insertion plate 31 are respectively provided on the sidewalls of the support plate 23 and the display module 3, which are close to each other. The bottom of the insertion plate 31 is inserted into the insertion hole 234, restricting the movement of the display module 3 along the width direction of the support plate 23, thus achieving initial stability restriction between the display module 3 and the support plate 23. Additionally, a support plate 235 is provided on the side of the support plate 23. The end of a bolt passing through the top of the support plate 235 is threaded into the frame of the display module 3, thereby restricting the lifting and lowering of the display module 3 and providing support for controlling the stability of the display module 3 relative to the support plate 23.

[0043] like Figure 12 As shown, with the display module 3 stably installed, in order to adjust the orientation of the display module 3, a central shaft located at the lower center of the support plate 23 passes through the sub-shell 22, and the central shaft is connected to a connecting frame via bearings. This connecting frame is connected to the frame below the sub-shell 22, thereby stably supporting the installation of the support plate 23. Additionally, a third worm gear 232 is fitted onto the end shaft 231 at the bottom of the central shaft of the support plate 23. A third worm is engaged on the side of the third worm gear 232, and the end of the third worm is connected to the power output shaft of the third motor 233. When the third motor 233 is working, it drives the third worm to rotate, thereby driving the third worm gear 232 and the central shaft to rotate, adjusting the orientation of the support plate 23 and the display module 3. The self-locking function of the worm gear ensures that the display module 3 is stably fixed after the orientation is adjusted. To facilitate the adjustment of the orientation of the display module 3, a camera 4 can also be installed on the top of the display module 3.

[0044] Example 2: As Figure 14As shown, based on Embodiment 1, in order to utilize solar energy to charge the battery pack 15, a photovoltaic panel 5 is provided on the side of the intermediate component 2. This photovoltaic panel 5 is connected to the circuit of the battery pack 15 and is equipped with an anti-reverse diode, a charging controller, etc. When charging the battery pack 15, current flows out from the photovoltaic panel, passes through the anti-reverse diode and charging controller sequentially, and is then stored in the battery. When the battery supplies power to a load device, current is output from the battery and flows to the device through the load circuit. The charging controller monitors the photovoltaic panel voltage and battery status in real time; when the photovoltaic panel voltage is ≥ battery voltage + charging threshold, charging is initiated; when the photovoltaic panel voltage is insufficient, the battery independently supplies power to the load. For remote monitoring, a smart controller with a Bluetooth / WiFi module can be selected.

[0045] like Figure 15 , Figure 16 As shown, in order to allow for the assembly and disassembly of the photovoltaic panel 5 as needed, the frame 51 and the main shell 21 of the photovoltaic panel 5 are fitted together. Vertical plates 214 and snap-fit ​​plates 52 are respectively installed on the side walls of the frame 51 and the main shell 21. The snap-fit ​​plates 52 are bolted into the snap-fit ​​grooves 215 of the vertical plates 214, and the top of the snap-fit ​​grooves 215 is open. When it is necessary to disassemble the photovoltaic panel 5, the bolts are removed to release the snap-fit ​​plates 52 and the snap-fit ​​grooves 215, allowing the snap-fit ​​plates 52 to be pulled out from the top of the vertical plates 214, thus enabling the disassembly of the photovoltaic panel 5.

[0046] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
