Description
Technical field
The present invention relates to a kind of vehicle booking service system, especially a kind ofly be used for wireless communication network system and the data management system that taxi is called out.
Background technology
In modern society's life, going by taxi is one of trip mode of often selecting for use of people, tradition " beating " pattern is that the passenger waves in the roadside and illustrates taximan's carrying of stopping, this method of calling is not enough to satisfy people's demand, as peak period on and off duty, potential passenger is a lot, and the phenomenon that taxi quantity can't satisfy passenger demand often takes place, and traditional approach can't be dispatched to coordinate this unbalanced supply-demand relationship taxi.Unloaded taxi place distributes and potential passenger place distributes inconsistent, some people from highway section Duo Che are few, and then the few car of people is many in other highway sections, and not only some passengers' demand by bus can't be met, make passenger's difficulty of going on a journey, and cause the waste of traffic resource and the waste of the energy.
CN1426241A, the invention of title " a kind of call display system for taxi ", comprise address open call, computer system, radio transmitting system, be installed in the electronic chart that radio receiving system on the taxi and energy show the concrete street locations of the address open call of each calling assigned number, the taximan can know caller's position by this map.The advantage of this cover system is accurate positioning, but the address open call fix, call out underaction, be not very convenient concerning the user.
CN101287157A, the invention of title " method for taxi dispatching and the system of the control scheduling of both-end satellite communication central authorities ", adopted a kind of both-end satellite fix method for taxi dispatching, utilize satellite that taxi is positioned, and be that the user serves with the powerful data processing function of satellite, the advantage that this patent relates to method is that the location is accurate, but system complex, and input cost is high and the consumption in actual motion is big.
CN1499387A, the invention that title " is rented the taxi system ", the method for employing portable terminal and system, the system that is used for taxi comprises: portable terminal device is installed in terminal and calculation element on the taxi.Portable terminal device can detect current position by GPS, and near taxi transmission message, so that taxi goes to, calculation element will calculate the distance and the time of distance users, but user's emitter volume is big in this method, cost is high, is not easy to carry also be not easy to popularize.And because handing-over place reason, taxi can not be accepted and the different user of place direction that hands over to the next shift under the situation of empty wagons, so even the information of empty wagons has been sent to the user, can not guarantee meeting of supply and demand.
Summary of the invention
The present invention is intended to address the above problem, and a kind of technical scheme of handling the chauffeur problem easily, automatically is provided:
The hardware components of novel radio network calling system of taxi of the present invention comprises user terminal, car-mounted terminal, base station and system host, and software section comprises wireless communication protocol and data base management subsystem.
User terminal of the present invention is made up of keyboard, display screen, control module, radio receiving transmitting module and antenna, and its structure annexation as shown in Figure 1.This user terminal can send out the call signal of hiring a car to the base station, and receives the information that reply the base station.
Car-mounted terminal of the present invention is made up of keyboard, display screen, control module, wireless transmitter module, antenna and loud speaker, and its structure annexation as shown in Figure 2.This car-mounted terminal can receive the information of the customer call taxi of base station broadcast, and sends confirmation signal.
Base station of the present invention is made up of controller, memory, radio receiving transmitting module and antenna, and its structure annexation is referring to Fig. 3.
System host of the present invention is made of server system, and major function is the information of all base stations of management, car-mounted terminal, user terminal, and regularly sends user's lastest imformation to the base station.
Software section of the present invention comprises wireless communication protocol and data base management subsystem, can send data in the base station towards periphery by a base station, up to all base station update all information by the mode of broadcasting; Simultaneously, when not having taxi near the base station, user's call information can provide service from other base station scheduling taxis for the user by this base station base station broadcast towards periphery.
Operation principle of the present invention and flow process are as follows:
(1) system host is used for storage and management taxi information and user profile, regularly updated information is sent the base station towards periphery.
(2) information is received in the base station, and then peripherad base station broadcast information, and the base station around making also obtains information, all obtains information up to all base stations
(3) EP (end of program)
After the user profile that obtains to upgrade when the base station, just can carry out call service.Basic calling order is:
(1) user sends the chauffeur request to the base station, and transmission comprises information such as number and user position by bus.
(2) after the base station obtained user's request, peripherad immediately taxi was broadcasted this information.
(3) can provide service if receive the taximan of information, send response message by acknowledgement key.
(4) base station sends to first taximan who presses acknowledgement key with user profile.The base station sends out the relevant information of hiring a car to the user simultaneously.
(5) if in official hour, taxi arrives the user site, and then taxi and user send confirmation.
(6) chauffeur process finishes.
(7) even if sending the taxi Iterim Change route of confirmation can not arrive in, then taxi can send the information of removing agreement to the base station, and repeats (1) to (5) operation once more and finish until calling procedure, and workflow as shown in Figure 4.So once successful service routine has just been finished.
Compare prior art, the present invention has following advantage:
(1) user terminal is simple in structure, volume is little, the rectangular portable band of stand-by time.
(2) base station and user terminal, taxi terminal communication are stable, reliable.
(3) simple, the easy row of the call flow that is adopted.
(4) realized timely communication between passenger and the taximan, reduced waiting time, prevented that peak period passenger on and off duty is detained, and convenient passenger's trip from far-off regions.
(5) reduce the taxi rate of empty ride, energy savings has improved taxi operation efficient to a certain extent.
This system group network is simple, and user terminal adopts energy-conservation facility, and with using with opening, volume is small and exquisite, and stand-by time is long.The base station is highly sensitive, and taxi terminal display complete function is easy to operate, and the power supply of reason self power supply can realize communicating by letter at any time.
This system popularizes, to change the custom of the passive wait taxi that people use always, it is convenient that the passenger is gone on a journey, and increased the utilance of resource greatly, and, help the sound operation of taxi trade by the service state that passenger feedback can the effective supervision taxi.
