Description
Technical field
The present invention relates to a kind of electronic bus stop board control system and method thereof, specifically use the station board control terminal of intelligent communication public traffic network management system.
Background technology
Existing domestic public traffic management system still continues to use pattern and the equipment before the more than ten years, adopts the management of " fix a point dispatch a car, two stuck point " handwork formula basically.This management mode can not adapt to the present situation of current urban transportation and vehicle management.
Existing comparatively outstanding contradictory factor is to take advantage of to lack a kind of interactively communication approach between a public of use bus and the public traffic management system, and mutual information is difficult to exchange.Such as existing public bus network station board, can only issue the circuit site information with fixing display mode, but can't dynamically demonstrate the real time execution information of bus on the circuit, play the information of prompting help for traveler, also have the remaining time that how far also has, arrives our station as next vehicle that enters the station what or the like all have no way of providing.Because the trip public can't recognize current bus operation situation, thus also just can't make correctly according to self plan of travel, circuit and selection of time timely, aggravated to a certain extent the public transport transportation crowd and uneven; On the other hand, the public traffic management system still rests on the level of manual maintenance and monitoring for the renewal of system own and equipment, lacks application modern network and mechanics of communication and sets up a kind of systematized self check and remote maintenance means.
Foregoing belongs to the information terminal problem of public traffic management system, had influence on also in the application and the degree of awareness of the public of going out the public traffic management system, as not solving the unbalanced and disordered state that still can cause city bus transportation, thereby be to be badly in need of the problem that solves.
Summary of the invention
Electronic bus stop board control system of the present invention and method thereof, being intended to address the above problem with deficiency provides the interactively network information processing terminal that is applied to management system of public traffic.Described electronic bus stop board control system can be issued vehicles of public and related service information.
Electronic bus stop board control system of the present invention is the information processing terminal as the public traffic management system.The electronic bus stop board control system is used the GPRS home control network communication protocol, sets up data communication with the control centre of public traffic management system, and the information real-time release that control centre is sent, can realize remote system upgrade simultaneously.
Wherein, control centre is by the applying GPS navigation system, the public transit vehicle of runing is located and the interactive data communication in real time, by control centre the position and the distance relation of vehicle and station board sent to electronic stop plate, thereby the relevant information of the operational vehicle on the circuit in time and accurately is distributed on the station board passenger's the sharing of having realized waiting to bus dispatching information.
Electronic bus stop board control system of the present invention, it mainly is to utilize existing GPRS wireless communication technique and the function of the external real-time release of data message that realizes control centre is sent.
The GPRS communication of electronic bus stop board control system and control centre can be set up by APN private network pattern, and control centre and all terminal station boards all transmit by designated lane.
On each the public bus network website on the electronic stop plate an outdoor luminous tube is set, when this website has bus to enter the station and do not leave, indicator light that then should the station is bright; In addition, more significant information indicating is dynamically to change, demonstrate next bus to enter the station required remaining time on set LED screen, thereby demonstrates the information of the required grasp of passenger of going out intuitively.
Electronic bus stop board control system of the present invention, nucleus module as the public traffic management system terminal, mainly set up interactively data information transfer mode, and be responsible for management simultaneously information issue display screen, power supply and time opening controller, vehicle location and turnover station display screen by GPRS communication interface module and public traffic management System Control Center.

Addressing+little classification (ASCII) in Data Source=big classification+station board
In the big classification, " 0 " is represented by control centre's forward data file, and nonusable routine;
In addressing in the station board, the serial number of all station boards in this public bus network of concrete numeral,
As first station board of " 1 " expression, other by that analogy.
In the little classification, adopt ASCII to represent the classification of " information content " accordingly, as
" 9 " expression " information content " is the Word message that is presented on the LED screen, phase
Should be shown character string content in the ground " information content ";
" 1 " expression " information content " is that public transit vehicle enters the station remaining time, and is corresponding
In the ground " information content " is numerical value remaining time;
" 2 " expression " information content " is the existing position of public transit vehicle, correspondingly " letter
The breath content " in be information such as public transit vehicle has entered the station or set off.
For example, the data file that enters the station remaining time of a public transit vehicle of being sent by control centre is:
0x7e, 0,1,1,0x08,0x7f, then expression still has just can enter the station 8 minute remaining time.
As shown in Figure 1-Figure 3, electronic bus stop board control system of the present invention needs to transmit echo message to control centre after receiving data file, and its data chainning file structure is:
Initiation of communication symbol+this machine sequence number+sign off symbol, wherein,
This machine sequence number is the sequence number of this electronic stop plate.
For example the echo message of above-mentioned station board should be: 0x7e, 0,1,0,1,0,0,0,1,0,0,0,0x7f.
