 Programme introduction
Lookout bus video monitoring system solution scheme for bus operation monitoring, dispatching and security counter-terrorism needs, provide bus, car video monitoring and vehicle positioning function, implementation of bus passengers and company by personnel monitoring activities, the vehicle driving process record, of fare evasion, our Passenger Fare theft, our multiplication / passenger disputes, theft, terrorist incidents, scratch vehicle collision accident monitoring and forensics, easy post duty. Through the bus vehicle video monitoring system, personnel scheduling can real-time master bus operators and vehicle location and thus reasonable dispatch and arrange the operation plan, regulators could monitor the driver driving behavior, to standardize the driver according to the regulations to operate and civilized driving behavior.
 
Background and challenges
Video surveillance system is not used in the traditional bus industry, can effectively solve the bus in security monitoring, monitor fare evasion and our Passenger Fare theft, vehicles in operation process happened scratch vehicle or collision and other traffic accident, afterwards, can never be identify accident responsibility and central regulators can not real-time to grasp the operation of the vehicle terminal subsystem, operators of buses in "invisible, inaudible" backward situation.
 
Solution
Lookout bus video monitoring system iVMS-7200 mobile video surveillance management platform based on, through 3G / 4G network access to the vehicle in front, real-time monitoring, video playback, GIS map location, track playback, equipment status query, emergency alarm and other functions.
 
The front end of the vehicle contains vehicle hard disk video recorder (referred to as the Car DVR or mdvr), car special camera, on-board LCD display, alarm button and a state display terminal, full duplex voice intercom box, car special fireproof storage box and supporting the cable wire. Vehicle mounted DVR built-in wireless network communication module, GPS and Beidou Positioning module.
 
 
Project advantage
1) no fan, fully enclosed design
Car DVR host enclosure using a non fan, fully sealed integrated design, can effectively avoid the dust inside the bus, water vapor, debris into the equipment, to adapt to the complex environment within the bus. Using aluminum die-casting / tensile aluminum box, the main heating elements attached to the shell mode design, can effectively guarantee the equipment internal heat is conducted to the shell of radiating outward.
 
2) special aviation head interface
Car DVR interface, power supply, sound video interface, and communication interface etc. are used special aviation head design, integrated mixed signal wire of the power line and signal wire and ground wire etc. together, through to ensure reliable pin and socket, thread and other signal reliable connection, to avoid bus driving vibration in the process of contact of the electrical continuity impact.
 
3) independent vehicle power module
Car DVR with built-in power supply module conforms to ISO 7637-2 (JAE1455) international standards, to adapt to different types of 12V and 24V, support the 8V to 36V wide input voltage, 12V and 5V output voltage, the power supply module with fast self recovery electron short circuit protection function, effectively avoid over flow with overload and short circuit protection. External power supply support hot swappable, the surge and load transient effective protection, can effectively restrain the load dump generated when the 200V, persistent hypertension 400ms. Using independent power module design, convenient for the maintenance of the latter can be replaced by direct module.
 
4) multi mode video recording mode
Car DVR can be built in 2.5 two inch hard drive, can use ordinary video, video recording, video recording, video data storage, can protect the mechanical hard disk working life, to ensure the integrity of the video.
 
5) built in super capacitor module
Car DVR built-in super capacitor module, can provide short term power supply. When accident happens in the vehicle, violent collisions cause power provided by the battery disconnect, provide a short time power supply guarantee the memory inside the key video data can be well written to disk; when the equipment of the abnormal power down to hard disk in accordance with the normal shutdown process operation, such as read and write head normal homing etc., very good protection of the hard disk life assurance. Compared to lead-acid batteries, lithium batteries and other back power, super capacitor module with charging and discharging cycle times a million times, and the work of a broader range of -40 degrees to 70 degrees Celsius, and from follow-up maintenance work.
 
6) can replace the communication module
New Car DVR with plug communication module design, different from previous communication module directly welded joint on the motherboard, in the case of the case is not open, convenient and direct replacement of different network standard communication module, convenient follow-up without returns to the factory can be upgraded network standard.
 
7) alarm and video backup
When the driver trigger an emergency alarm button, the alarm signal transmission to the Car DVR host, this time can be to trigger the alarm time in front of a period of time and after for a period of time of the video data, storage to the built-in SD card or take fireproof storage box, to achieve the key video data backup function. Especially in the case of the occurrence of vehicle fire, better protection of the scene of emergency video data.
