Vehicle monitoring system program introduction

With the rapid development of the economy, the number of domestic logistics trucks is increasing. The safety and supervision of vehicles has become a matter of great concern to vehicle owners, especially for large trucks, large construction machinery vehicles and other driving units. Transportation machinery. A project we implemented in Beijing, the cost of customer vehicles from Beijing Chaoyang District to Guangdong Shenzhen is between 2.7 and 32,000, 2.5-3 miles per month. After installing 3G video surveillance, each vehicle runs 3-3.5 per month. Hey, the cost of a single round trip has dropped to 2.4-28,000. The way to save costs is as follows: 1. Install a 3.6MM lens camera on the inside of the tank to monitor the display data of the tanker to check the authenticity of the reimbursement bill. Solved the problem of invoice openness, and the real-time monitoring of video also solved the problem of stealing oil; 2. Install a camera before and after to monitor the traffic conditions before and after the vehicle, which can prove the driver's “blocking traffic”. The lie can also be used to distinguish the responsibility of the accident when the accident occurs. 3. Slow crawling on the national road. When the fuel costs, the driver can use the high-speed toll invoices bought to earn a large toll. The camera has completely solved the problem of high speed slow running;

4, due to the implementation of a full range of video surveillance, there will no longer be a "boss, the tires should be replaced!" situation; 5, install a camera in the front of the car position, monitor the car's cargo changes, completely eliminate The problem of private distribution. You can use the current 30 vehicles to solve the traffic volume of the previous 40 vehicles, reduce the single freight rate by 10-15%, minus the driver's salary increase cost (there is a strike phenomenon), and comprehensive statistics, the profit level of each vehicle is improved. 25%.

In the traditional vehicle-mounted mobile monitoring, due to the limited network conditions, the video of the vehicle is often recorded and saved. Some manufacturers try to transmit the instant video of the video and video, but the effect is not satisfactory, and the video surveillance function cannot be truly played. With the continuous popularization of 3G networks, in the 3G network environment, the network bandwidth is multiplied, which can meet the video data transmission requirements of high frame rate and high image quality, and supports uploading images and accepting distant images at any place, making it impossible in the past. The technical problems realized can be solved under the improvement of 3G wireless transmission technology. The original car-based video surveillance solution based on video is gradually developing towards systemization, networking and platform.

Front end design

Front camera

The front-end camera is mainly responsible for collecting video information inside and outside the car. In order to ensure the safety of the vehicle and personnel, the coverage of the camera is required to reach 95% or more, ensuring no dead angle inside and outside the car. The front-end camera adopts 2.8mm or 6mm lens color to black infrared night vision high-definition CCD camera, camera resolution is above 480 lines, illumination black and white 0.01lux, color 0.3lux; camera through 3G car video positioning terminal host to take power.

Since the size of various vehicles and the structure inside and outside the vehicle are very different, the number of cameras to be used and the position of the installation must be designed in consideration of the actual situation of the vehicle.

Take the freight car as an example here for a brief explanation. A normal freight car needs to install at least 4 cameras to monitor various positions in the car, as shown below:

1) Camera No. 1

Front road camera - The roof plate installed in front of the driver's seat, the lens facing the road ahead, shooting the road ahead, driving signs, traffic lights, etc., can record the driving condition of the vehicle and the driving condition of the vehicle ahead.

2) Camera No. 2

Cab Camera - Located in the cab of the freight car, it is used to capture the driver's safe driving situation and sound recording, which is conducive to improving the driver's awareness of traffic rules, ensuring driving safety and identifying accident liability.

3) Camera No. 3

Fuel tank camera - installed on the inside of the tank under the car floor, the lens is facing the outside of the car, mainly shooting the state of the fuel tank cover and the display data of the tanker

4) Camera No. 4

Car camera - The car's outer roof is located at the top of the rear side of the truck. The lens is oriented backwards to basically capture the loading and unloading of the car and the road behind it.

Front pickup, speaker

The front end of the system is equipped with a device pickup for sound collection, which can be used for real-time collection and dialogue of sounds in the car, and the intercom is initiated as a center.

Digital video and audio coding

The analog video and audio signals collected by the front end are connected to the digital 3G video vehicle positioning terminal host for digital compression processing. First, the analog video and audio are digitally encoded, and then compressed, and the processed data is stored according to requirements and uploaded by the wireless network.

GPS positioning module

The vehicle terminal device can periodically transmit the positioning information of the Global Positioning System (GPS) GPS to the management center through the wireless network transmission system, and the management personnel can obtain information such as the trajectory, speed and direction of the vehicle in the monitoring center. . Our BE-A16C mainframe adopts the Swiss UBLox LEA-5S satellite positioning module, which solves the problem of rapid restart and rapid positioning of the positioning system.

Emergency button (optional)

The emergency alarm button can be installed on the vehicle. When an emergency occurs in the vehicle, the alarm button can be triggered by the driver and the police to report to the management center. The management center responds quickly.

LCD display (optional)

The system is equipped with a 7-inch color LCD screen in the cab for the driver to observe the inside of the car. The display adopts progressive scanning with a resolution of 800×600. The driver provides remote control to switch between displaying the inside and outside of the car. You can select single screen or browse four screens. The administrator can use the remote control to implement related functions such as data query, system upgrade and data download. .
