Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Fig. 1 is the system framework figure of one embodiment of the invention.
As shown in Figure 1: a kind of electronic station board system comprises: be arranged on the electronic stop plate terminal that is used to show the bus arrival time on the public transport platform; Be arranged on and be used to receive gps satellite signal on the bus and the real time position of bus specific road section between the station and the bus car-mounted terminal that velocity information sends; Receive real time position that the bus car-mounted terminal sends and velocity information and through GIS to the real time position of specific road section between the station with velocity information is resolved and distance transform; Confirm the average velocity of specific road section between the station and calculate the bus arrival time; The station board that the bus arrival temporal information is sent to the electronic stop plate terminal shows the control platform
Described electronic stop plate terminal and bus car-mounted terminal show that through 3G communication network and station board the control platform is communicated with.
Wherein, specific road section is the highway section between two level crossings between the station between described station, and the average velocity that obtains through specific road section between the station can be considered the average velocity that this bus between current crossing to next crossing goes.
Described 3G communication network provides the respective communication service by telecom operators, is used to accomplish the communication function of total system.
Fig. 2 is an electronic stop plate terminal hardware composition frame chart of the present invention.
As shown in Figure 2: described electronic stop plate terminal comprises main control module, LED display, driver module, a 3G communication module and a power module; Described power module all is communicated with main control module, LED display, driver module and a 3G communication module; And described drive module setting is on LED display; And driver module, LED display and a 3G communication module all are communicated with main control module; Wherein, roll with the mode of literal through outdoor LED display screen and play line name, line information, current name of station, car time at the whole story, five essential informations of next name of station that comprise station board in the electronic stop plate terminal, and bus is apart from information such as our station station number, range information and last bus promptings; In addition; In the practical design process, also to make the electronic stop plate terminal need meet IP65 rain-proof dust-proof standard, lightning protection device need be set simultaneously at an upper portion thereof and set up wireless antenna.
Fig. 3 is a bus car-mounted terminal hardware composition frame chart of the present invention.
As shown in Figure 3: described bus car-mounted terminal comprises on-vehicle host, GPS module and the 2nd 3G communication module, and described GPS module and the 2nd 3G communication module all are communicated with on-vehicle host, and described bus car-mounted terminal receives gps satellite signal and the gps satellite signal that receives (coordinate information) is sent to station board and shows the control platform, and described on-vehicle host then is used to control GPS module and the 2nd 3G communication module; In this embodiment, also be reserved with IO interfaces such as video, voice on the described on-vehicle host, in addition; Described GPS module mainly provides the information of contents such as bus longitude, latitude, speed, direction, time, station-keeping mode, and carries out autonomous positioning, as the information that provides is: 074030.00; A, 3942.10575, N; 11810.52559, E, 0.879; 136.15,020210;, A*64 presses NMEA0183, also is used for simultaneously showing that with station board the control platform communicates.
In addition; Described station board shows that the control platform comprises that communication is with server, database server and display device;: have that data management, electronic chart show, gps data converges, releasing advertisements and Core Features such as commonweal information, information issue, be used to receive bus positional information and carry out that GPS resolves and distance transform after relevant information is distributed to each electronic stop plate terminal.
The key that converts is according to the average velocity estimation of specific road section between the station and shows arrival time; As communication with server receive foregoing bus car-mounted terminal provide information after, database server is therefrom resolved the following bus information that obtains: latitude 3942.10575; Longitude 11810.52559; Speed 0.879 joint, direction 136.15 degree, in 7: 40: 30 on the 2nd February of 2010 time, in addition, station board shows that the control platform also comprises the content distributed functional module of carrying out real time modifying in station board terminal.
The present invention makes full use of that existing 3G communication network transmission bandwidth is big, speed is high, steady performance; Realize whole electronic station board system efficiently, safely and steadly the operation; And it is not only simple in structure, practical and convenient, safe and reliable; And can fast, accurately obtain the bus arrival time, make the passenger can grasp the arrival time of bus at any time, so that arrange stroke better; Managerial personnel then can grasp each bar circuit position of bus in real time, so that rational management.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
