Specific embodiment
As shown in Figure 1, method and system provided by the present invention is to utilize the technology of radio call to realize sending and receiving the dynamic message of operational vehicle and show, and comprises in the system as lower device: a plurality of along the public bus network setting, site information transmitter 1 that can infrared transmission address code information, be arranged on and be used to receive and transmit the message pick-up transponder 2 of described site information transmitter information and the time basic controller of the described message pick-up repeater operation of control on each bus, a plurality of fixed points distribute and can receive the message pick-up repeater station 3 of described bus forwarding information, one is used to receive and receives repeater station with forwarding information and send information emission base station 5 and be arranged on the electronic display 4 that is used to receive information that send the base station and dynamic demonstration vehicle ' position on the bus stop.
The basic functional principle of system is: be arranged on every transponder on the operation public transit vehicle and send address signal and the vehicle identification signal that has passed through website, after each message pick-up repeater station receives processing, deliver to the base station by trunk, again by launching after the queuing modulation of base station, be located on the bus stop the electronics display board by the website that receives and vehicle message with vehicle the website of process show.
Along the public bus network setting, can be provided with infrared encoder and power transmitter in the site information transmitter of infrared transmission address code information, its course of work is; The address code that elder generation exports this website by coding circuit is encoded after power amplifier amplifies, and drives the Infrared High-Power luminotron and launches; The site information transmitter can be arranged on each platform, can also be provided with between adjacent two platforms, and it is more accurate that the how displayable bus traveling-position of quantity is set.
But controller is formed when being arranged on time base controller on the bus by radio frequency receiver and pre-programmed timesharing transmission and school, the course of work is during its school, when beginning, grouies busy when radio-frequency transmitter on every chassis begins the school each period and works that the repeater-transmitter of being controlled on every chassis by the single-chip microcomputer timing timesharing of the time that can prelist is launched address information in order in turn again by the base station; Also can be through adopting another kind of calibration method, in the time of can unifying the school every day with wireless or infrared emission mode in moment that bus starting station vehicle is concentrated once.
As shown in Figure 2, be arranged on and comprise the reception part in the message pick-up transponder on the bus and transmit part, be provided with infrared electro in receiving partly and receive head, decoding circuit sum counter circuit, its course of work is: bus through the site information transmitter time with the site address information decoding that receives after output one pulse make the hop counter counting; Transmitting address information input interface, radio call scrambler, radio-frequency modulator, power amplifier and the radio-frequency antenna that partly is provided with connection successively, its course of work is, earlier address information sign indicating number and bus identification information coding are input in the scrambler, be stored in again in the immediate access circuit, by the output of the time division circuit in time base controller control signal, drive radio-frequency power amplifier and again coded address information is launched.
As shown in Figure 3, be provided with in the message pick-up repeater station as lower device: radio frequency receiver, relaying transtation mission circuit and trunk, its course of work is: after radio frequency receiver receives the geocoding of vehicle forwarding, through demodulation outputting encoded data signal, send signal through the relaying transtation mission circuit from trunk and deliver to the base station.
As shown in Figure 4, in the base station, be provided with as lower device: insert computing machine, modulator, driver, high power amplifier and emitting antenna and power supply automatically, its course of work is: the coding vehicle address date that trunk is sent here is ranked, form continuous coded message in each period, the front end of each period insert again by the time base controller receive group busy correcting delay signal, more this complete coded message is launched from antenna behind modulated excitation.
As shown in Figure 5, be arranged in the electronics display board at station and be provided with: radio frequency receiver, demoder, data distributor, website row memory and circuit website pilot lamp array as lower device, its course of work is: receive the vehicle address information of sending the base station and be decoded into data message, again data message is delivered to allotter circuit and deposit website row memory in through scanning, promote the traveling-position that circuit website pilot lamp array dynamically shows operational vehicle again, array pilot lamp and site information transmitter have relation one to one.
For making the high efficiency of native system, display effect is good, branch at the emission frequency is mixed in the following way: transmitting base station uses a dominant frequency point emission information, calculate by radio call code rate 2400bit/s, in per 60 second period, can send the operation information of 1986 chassis, as improve speed or increase dominant frequency point again and assist frequency, system can contain more car; Operation information; Consider the factors such as delay of delay inequality and the trunk and the interlock circuit of transponder cataloged procedure, the message pick-up transponder that is arranged on the bus adopts two auxilliary frequencies to send information, all vehicles in the system are divided into two groups, each group adopts same auxilliary frequency to launch spaced discontinuous signal, do like this and can avoid application circuit complicated, and circuit when not needing the fine compensation school.
Radio call is a kind of unidirectional individual selective call information service, the present invention utilizes radio paging technology to realize the public transit vehicle operation electronics display station dot system of entire city scale, send the address of vehicle certain website of process in certain period and the modulation signals of information of vehicles by operational vehicle timesharing ground with the power radio communication transmitter, being demodulated to data-signal after a plurality of information repeater station that fixed point is provided with amplifies signal delivers to signal with transmitting base station by trunk, by transmitting base station to signal rank insert be modulated into high-frequency signal after, launch, the electronics display board that is arranged on like this on the bus stop can show the information of certain received bus through certain website on the electronics display board, only take the master in this system, three of auxilliary frequencies, be that launch with a dominant frequency point base station, all vehicles are by two auxilliary frequency timesharing emission in turn, and such system can hold the running status that shows nearly 2,000 buses; Though native system is not the mobile status that shows vehicle continuously, just (as 60S) takes the mode of great-jump-forward to show the vehicle position in a period of time; Enough these people that wait for bus for raising one's head and looking, the reliability of native system and utilization factor are all very high, but the operating cost of system is very low, the present invention is except that being used to show the vehicle ' position, the scheduling and the mixing system that can also be used for public transit vehicle, be a kind of being worthy of popularization, can promote the modern system of urban transportation.
