Description

Technical Field

[0002] Urban roads are infrastructure for trackless vehicles and pedestrians. Based on their usage, they are categorized as highways, urban roads, rural roads, factory and mining roads, forestry roads, examination roads, competition roads, automobile test roads, workshop access roads, and school roads. In ancient China, there were also post roads. They also refer to the means of achieving a goal, or the path of development and change.

[0003] During the use of urban roads, due to the increase in vehicles and traffic, it is necessary to monitor road traffic. Traditional monitoring devices generally use cameras to shoot the road in real time, identify vehicles through image analysis technology, and monitor traffic flow, vehicle speed, and queue length. This method is greatly affected by weather conditions such as fog and rain. In addition, speed bumps are required in some areas where speed control is required. Traditional speed bumps are mostly hard structures and cannot be adjusted to withstand pressure and hardness as needed. In addition, speed bumps cannot be effectively used to monitor road vehicles, which causes certain inconveniences. Based on this, a monitoring device for urban roads is proposed.

[0020] The working principle of the above technical solution is as follows: when in use, the user pre-buries the base plate 1 and the protective plate 7 inside the road, and fixes the base plate 1 by inserting bolts through the mounting holes 2. Then, the top of the base plate 1 and the protective plate 7 are covered with road asphalt, and then the road power supply line is connected externally through the power adapter 15.

[0028] Two base plates 1 and multiple protective plates 7 are a group, which is convenient for achieving effective speed limit and blocking effect on the road, and the distribution of the ring coil 18 and the connecting wire 19 is convenient for staggered connection of the two base plates 1, convenient for auxiliary installation and use, convenient for reducing the monitoring pressure of a ring coil detector 14, and convenient for coordinated use. The protective plate 7 is located at the center line position of the road, which is convenient for application to urban roads with different lanes and convenient for installation and use.

[0029] In another embodiment, Figures 1-4 As shown, the annular coil 12 is linearly and evenly distributed at the bottom of the inner cavity of the trapezoidal rubber inner tube 10, one side of the protective shell 13 is in active contact with one end of the trapezoidal rubber inner tube 10, the specifications and dimensions of the protective shell 13 are adapted to the specifications and dimensions of the trapezoidal rubber outer tube 5, and the output end of the annular coil 12 is electrically connected to the input end of the annular coil detector 14 through a wire.

[0030] The protective shell 13 protects the toroidal coil detector 14, the power adapter 15 and the wireless network transmitter 16 to increase the force.

The output end of the power adapter 15 is electrically connected to the input end of the power input of the toroidal coil detector 14 and the wireless network transmitter 16 to facilitate power supply. The current output end of the toroidal coil detector 14 is electrically connected to the input end of the toroidal coil 1 and the connecting wire 19 through a wire to facilitate control. When a vehicle passes by, the metal part of the toroidal coil 12 and the toroidal coil 2 18 of the vehicle will change the magnetic field distribution around the coil. Due to the presence of the vehicle, the coil The inductance changes. When the vehicle is just above the coil, the magnetic field of the coil is most affected by the vehicle. At this time, the inductance change of the coil reaches a relatively stable value. By detecting the change in this inductance, as the vehicle continues to move forward and leaves the coil area, the magnetic field of the coil gradually returns to its original state, and the inductance also gradually returns to its initial value. The ring coil detector 14 continuously measures the inductance change of the coil and converts these changes into electrical signals. These electrical signals are processed and analyzed, and the signals are sent to the traffic control background through the wireless network transmitter 16. The vehicle's passing conditions, such as traffic flow, speed, lane occupancy and other traffic parameters, can be obtained. The overall solution effectively integrates the speed bump and road monitoring functions, thereby monitoring vehicles in areas where traffic speed limits are required, and the overall use effect is good.
