Speed capture system
Product Details
The speeding capture technology scheme measures the speed and image monitoring of the road surface at a specific location using Doppler frequency change technology to measure the speed of moving vehicles. When the moving target exceeds the initial plastic value, the system receives a radar detection trigger signal, and uses a camera to capture near and far range images of the speeding vehicle. Then, through the data acquisition system, the images are sent to the industrial computer for image signal processing, Thus obtaining a clear image of the illegal target.
Provide standard definition and high-definition solutions
system composition
The speeding capture system consists of four parts: front-end vehicle detection component (video) and radar, capture host, license plate recognition system, and capture system illegal management software.
System working principle
The system monitors the speed and image of the road surface at a specific location, using Doppler frequency change technology to measure the speed of moving vehicles. When the moving target exceeds the initial plastic value, the system receives a radar detection trigger signal, and uses a camera to capture near and far range images of the speeding vehicle. Then, through the data acquisition system, the image is sent to the industrial computer for image signal processing, thereby obtaining a clear image of the illegal target, At the same time, it can generate illegal images and speed information databases, and generate illegal penalty notices according to actual requirements, providing traffic management as the basis for law enforcement.
Main characteristics of the system
◆ Adopting advanced microwave technology, effectively compressing the radar beam width, reducing the irradiation area, and completely overcoming interference from vehicles on the road.
The system's capture is constrained by multiple conditions such as video discrimination and triggering of speed measurement radar, greatly reducing missed and false capture rates.
◆ Advanced image processing technology is adopted to accurately and clearly capture the position of the captured image. A panoramic and close-up image can be captured, and the captured image can clearly distinguish the illegal time, illegal location, illegal type, vehicle model, license plate number, vehicle color, and other content.
The system adopts an embedded operating system based on industrial computers, which has system protection and self recovery functions, effectively preventing malicious attacks from computer viruses and hackers. Provided system security and stability.
The embedded operating system carrier adopts a highly reliable industrial grade electronic disk that is resistant to harsh environments. Compared to ordinary hard drives, electronic disks have the following advantages: strong shock resistance and pollution resistance; No noise, no seeking errors, especially due to its excellent performance in shock-absorbing function, it is widely used in industrial control environments.
◆ Multi directional and multi lane (up to eight lanes in both directions).
◆ Power off and restart, the host can work continuously for a long time. Once the power is cut off and shut down, the host can automatically run the program after a power call.
◆ Equipped with lightning protection, ventilation, heating, and automatic temperature control functions.
◆ Advanced fill light technology, the capture system adopts a long-life and high brightness LED fill light, and applies video synchronization technology. The fill light does not light up normally, but only turns on when confirming the capture and turns off after capture.
◆ Transmission function, the system has wired and wireless communication interfaces, which can automatically or regularly transmit captured images to the penalty center, and receive instructions from the penalty center for real-time data transmission and historical data transmission.
In terms of system security design, there is a monitoring unit that can achieve dual monitoring and protection of software and hardware. When there are problems with the system software, the system can be reset to restore its operation. Once the software fails, the hardware monitoring system can reset the entire host system, achieving dual protection and improving system security and stability.
