In recent years, school bus-related traffic and safety accidents have occurred frequently in China, and the safety of students on school buses has not been guaranteed. Only in Dongguan City, according to statistics from the traffic police department, a total of school buses have been involved in the city from 2010 to October 15th. There were 37 traffic accidents, resulting in 6 deaths and 36 injuries. Among them, there were 25 accidents where school buses were the main responsibility, resulting in 5 deaths and 22 injuries. Especially in September 2010, two school bus safety accidents occurred one after another in Zhongtang and Dalang Town of Dongguan City, resulting in the death of two students. In foreign countries, although the government has given more protection to students in terms of school bus quality and related laws and regulations, it still cannot prevent students from fighting on school buses, school bus traffic accidents and other vicious cases. To sum up, schools, parents and related government agencies urgently need the campus vehicle safety monitoring and management system to achieve the following functions:
1. Prevent all kinds of criminal activities against students on the school bus
2. Avoid violent incidents such as fights between students on the school bus
3. Track student locations throughout the process
4. Monitor school bus drivers’ speeding, fatigued driving and other vicious driving habits
5. Put an end to school bus overcrowding, overloading and other violations of laws and regulations, and record all kinds of violations and incidents throughout the process
Features of front-end equipment
Real-time monitoring of school bus operation process:
The on-board embedded monitoring system can realize multi-information real-time monitoring. The on-board driving record terminal continuously reports the driving status and real-time position information of the vehicle at preset time intervals, and stores it. It can understand the driving status and operating environment of the school bus in real time, and discover in time Environmental or human problems, including random parking, irrelevant rides, etc.
Emergency linkage for emergencies
In the event of an emergency, the on-board embedded host uses cameras installed everywhere in the car to record relevant information in real time and send it to the monitoring command center, traffic control, evacuation of people around the accident site, emergency rescue of accidents, etc. Measures to facilitate timely handling of accidents.
Positioning monitoring during operation:
Through the GIS/GPS geographic information/satellite positioning system of the vehicle-mounted embedded host, the positioning signal can be transmitted to the monitoring and dispatching center. The monitoring and dispatching center uses differential technology to convert it into position information, and then uses GIS to display the position signal in map language, navigation, service and rescue trajectory recording and other functions.
The realization of the alarm function:
The vehicle-mounted embedded host has an alarm input interface, which can be connected to any conventional alarm equipment. When an alarm occurs, the alarm information is transmitted remotely to the monitoring center. On the GIS map of the monitoring center, the corresponding icon of the vehicle will keep flashing, license plate number, driving route, etc.) and driver information (such as name, age, etc.) Driving experience, etc.) will be displayed automatically. The video signal corresponding to the vehicle is transmitted to the monitoring center through the WCDMA network, and the vehicle is monitored remotely. Combined with GPS and electronic maps, the police can immediately know the location of the vehicle,
Respond quickly accordingly.
Alarm type: overcrowded, overspeed, temperature, video loss, line, etc.
Overcrowding: The host records the number of people getting on the bus each time, and every student will swipe the IC in his hand once when getting on the bus.When the number of people in the car is greater than a certain limit, the host sends the overcrowding alarm to the center through the 3G network
Overspeed: host passes GPS The system obtains the vehicle speed. When the vehicle speed exceeds a certain limit, the host automatically sends an alarm message to the center.
Temperature: The temperature sensor connected to the host can measure the ambient temperature and record the temperature as a curve.
Video loss:
Route: GPS information records the driving position of the school bus, and can view the position of the school bus in real time or replay the running track of the school bus.
RFID vehicle-mounted man-machine interface:
When the driver is in reverse gear, he can passRFID The on-board human-machine interface observes the situation behind the car to ensure safety when reversing. Students can also swipe the student card through the human-computer interaction interface, and send the student boarding information to the back-end monitoring center through the vehicle-mounted host, and send the information to the designated parent’s mobile phone. At the same time, parents can view the video of the vehicle in real time through the monitoring software deployed on the mobile phone, and observe the child’s ride.
Features:
Real-time image detection: Maximum support for a single PC to display 16 channels of images
Fleet management: support multi-level fleet management structure
Vehicle positioning: support real-time multi-vehicle map display
Track display: support historical data, playback map display
Alarm monitoring: support alarm linkage image, support alarm filtering
Support multiple map formats: support Google map, Mapinfo map
basic skills
Video capture: The front end of the system uses a high-definition, all-weather on-board camera, which can monitor the road conditions and the interior of the vehicle.
The situation is collected in the monitoring terminal in real time.
Sound collection: The front end of the system can collect the internal and external audio signals of the car into the terminal through the pickup, and the pickup can be integrated into the camera.
Audio and video: The hardware is used to synchronize audio and video signals into two data streams: images with high resolution and frame rate are stored on the hard disk, and images with low resolution and frame rate are used for network transmission.
Local preview:
Play back historical recordings. Operate the system through the display screen, and manage the position and direction of the camera.
RFID card swiping: RFID radio frequency identification card can be swiped, and the RFID card information is sent back to the background monitoring center.
