Guangzhou will comprehensively apply and promote the intelligent public bus transit system. Through the intelligent system, as for the bus on the "brain", for how to arrange the departure density to develop indicators. As soon as the passengers pass through the intelligent bus people counting sensor, they will be automatically and accurately counted. The dispatching center can immediately know how many passengers are on the vehicle and whether they are crowded. The driver only needs to press the intelligent button on the car, and then he will send a message to adjust the scheduling plan, and the dispatcher will send the next shift departure time to the intelligent machine on the car. If the bus breaks down or gets blocked on the way of operation, the intelligent dispatching system will know it as soon as possible and make appropriate adjustment. In the past, sometimes several buses of the same line come in at the same time, and sometimes passengers can't wait for the bus in a few minutes, which will obviously change. At present, the number of buses in Guangzhou has reached more than 8000, and the number of vehicles per capita is the first in China. The key to solve the problem of citizens' travel is not to increase the bus capacity. How to scientifically allocate the bus capacity through the intelligent bus system is the most important.
System description the its system combines embedded industrial control, wireless communication (GPRS, WLAN), satellite positioning (GPS), audio and video technology, LCD / LED display and other devices to become a vehicle traffic action system
The aim is to alleviate the contradiction of traffic demand, improve traffic capacity and reduce traffic load in the central area. The purpose of this stage is to make full use of the existing conditions, mainly to solve the traffic congestion in the central area, purposefully improve the traffic control center monitoring system, improve the traffic structure, reduce the traffic demand, and create the necessary technical conditions and traffic environment for its.
The system consists of two parts: host and peripheral. It can realize its functions in cooperation with LED and other related equipment on the vehicle.
The host includes: motherboard component, video component, differential GPS component, GPRS module, WLAN card, power supply, power amplifier, fan, box and harness.
Peripheral part: keyboard, LCD display, interior led, exterior led, GPS antenna, 4G router, mobile DVR, bus people counter and other expansion equipment.
1. Monitoring and dispatching
Traffic monitoring and dispatching can be handled by the system
2. GPS positioning
Carry out traffic position monitoring and background management and dispatching
3. 4G and WLAN data communication
The daily monitoring and scheduling information communicates with the background through 4G real-time online network. Including: positioning data, vehicle operation information, vehicle scheduling information, driver check-in information, system information, etc.
After the vehicle arrives at the main station or parking lot, the large data information such as video monitoring image file is transmitted to the background through WLAN network, and the data such as line information, station announcement voice file and media information are received at the same time.
4. Voice docking communication
When driver and dispatcher need voice communication, it can be realized through DVR docking system. So that data transmission and voice communication can be carried out at the same time.
5. Voice station announcement and display station announcement
The terminal calculates whether to enter and leave the station according to the positioning data, and opens the station reporting function according to the line information stored in the terminal. The terminal has built-in voice power amplifier, led and LCD display driver module, which can realize voice station reporting, LCD screen and LED screen inside and outside the vehicle.
6. LED information display inside and outside the vehicle
The LED screen inside and outside the vehicle can display the station name, service information, advertisement, etc. according to the terminal pre stored program or the driver's key command.
7. Multiple LCD information display and digital TV interface reservation in the vehicle
The terminal has video output interface, supports LCD screen, the number of LCD screens, and can be expanded to more than 3 through video conversion module. At the same time, the terminal also has large capacity memory, pre storage of multimedia files for vehicles to play advertisements, entertainment programs, etc.
8. Collection of vehicle driving and operation information
In addition to receiving the information of driver's going to work, operation check-in and so on through keyboard, the terminal can also expand more functions through its peripheral equipment:
(1) Bus video passenger counter (www.ifootfall.com)to collect the passenger number information of public passenger buses.
(2) Door magnet sensor: collect the door switch status.
(3) Mobile video recorder: collect mileage, overspeed, fatigue driving and other information. Mileage can also be used as the auxiliary positioning basis.
9. Video surveillance inside and outside the vehicle
The video surveillance cctv component in the vehicle is composed of a video server and a multi-channel camera. The system structure is as follows:
