Preferably, native system can adopt two kinds of mode of operations, is respectively automatic mode and manual mode, can be switched to manual mode carry out emergency operation when automatic mode goes wrong, and ensures the normal operation of system.
This controlled in wireless sound broadcast System Working Principle and process as follows:
Vehicle-mounted control terminal on vehicle adopts a HT46F49E single-chip microcomputer as the controller of vehicle-mounted end radio receiving transmitting module 12.Each platform installs platform control terminal, and it comprises platform end radio receiving transmitting module 22, signal by wireless transmit head by coding chip constantly to wireless signal emission within the scope of certain radius.Wherein vehicle-mounted control terminal also comprises 12864 vehicle-mounted end LCD MODULE and vehicle-mounted end voice broadcast module 13 etc.Vehicle-mounted end radio receiving transmitting module 12 to be decoded the signal received by decoding chip by wireless receiving head, the port of HT46F49E vehicle-mounted end single-chip microcomputer 11 pairs of vehicle-mounted end radio receiving transmitting modules 12 scans, when vehicle is about to arrive at a station entering signal scope, port level changes, HT46F49E vehicle-mounted end single-chip microcomputer 11 recognizes the rear inner playing pointer of speech chip first calling vehicle-mounted end voice broadcast module 13, allow it point to preset data segment, and report.Change the LCD displaying contents of vehicle-mounted end LCD MODULE simultaneously, the name of station of the next stop is upgraded.Then drop-off indication lamp lights, and notifies to arrive at a station passenger getting off car.Vehicle is departed blackout after platform, and pilot lamp extinguishes.
In controlled in wireless sound broadcast system, adopt HT46F49E as main control singlechip.The advantages such as it is a 8 high-performance reduced instruction set computer single-chip microcomputers, has antijamming capability strong, low in energy consumption.Vehicle-mounted end radio receiving transmitting module 12 and platform end radio receiving transmitting module 22 then adopt nRF24L01 and peripheral circuit thereof to form, nRF24L01 is a monolithic wireless transceiver chip being operated in 2.4-2.5GHz Global Access ISM band, and it comprises: frequency generator, enhancement mode SchockBurstTM mode controller, power amplifier, crystal oscillator, modulator-demodular unit; Output power, channel selection and arranging of agreement can be arranged by SPI interface.Extremely low current drain: be 9.0mA when being operated under emission mode emissive power for current drain during-6dBm is 12.3mA during receiving mode.Under power-down mode and standby mode, current drain is lower.Have recorded the line coding assigned by the bus of every road in HT46F49E, can switch by controlling up-downgoing switch 15 the up-downgoing vehicle that bus routes coding distinguishes same circuit simultaneously.For saving energy consumption, utilize main control singlechip that a timing 100ms is set, go out to be loaded with the coded signal of particular course mark every 100ms transmitter module through antenna transmission, then before next 100ms arrives, whether cyclic query receiver module has the feedback information receiving platform control terminal to determine the action of next stage.If during this period of time do not receive any feedback signal, then continue outwards to send coded signal; If vehicle-mounted control terminal have received the feedback information of platform control terminal before next 100ms arrives, then compare and judge that whether information is correct.If feedback information is correct, by stopping sending coded message 30s, (this time is that the bus of estimation is from sailing in platform effective range 100m to vehicle-mounted control terminal, to rolling institute's time spent outside this effective range away from), to reduce the information processing capacity of platform control terminal, after 30s, return to original duty again; If feedback information mistake, then vehicle-mounted control terminal will not process this feedback information, continue timed sending coded signal.After starting platform control terminal, platform control terminal is in received encoded signal state, whether receives information do next action by inquire-receive module.If receive coded signal, and verification is correct, then feed back an answer signal (answer signal is the coded signal received) to vehicle-mounted control terminal, and by HT46F49E single-chip microcomputer, analytical calculation is carried out to the line coding received, obtain corresponding bus line number, from the bus route information storehouse stored, read corresponding route information again, provide word and voice message by LCD display system and voice system.Because the communication between bus and website is realized by wireless receiving and dispatching signal, there is the interference of various noise (comprising the coded signal of All other routes bus) in the channel, easily cause error code, parity checking and the form of shaking hands can be adopted this to confirm the information received.Secondly because the bus of the uplink and downlink of two-way lane is all likely simultaneously within the valid analysing range of a platform, in order to prevent the bus that the arrives at a station bus that opposing lane travels being mistakenly identified as this track, we carry out specific coding to identify bus, main method is as follows: adopt 8 bits (1 byte) to be numbered bus, get its first place (D7) as the discrimination bit judging bus up-downgoing, so every road bus is all to there being two codings, one is up coding, a downlink coding.Being encoded to of such as the 1st bus: 1 up bus be encoded to 00000001B, 1 descending bus is encoded to 10000001B.The conversion of up-downgoing coding is realized by a hand switch.Like this for certain platform, when the first place of the coded message received is identified as up train for time " 0 ", for arriving at a station bus, thus it is further processed; When the first place of the coded message received is identified as down train for time " 1 ", thus give up this information.When bus by up transfer descending (or by descending transfer to up) to time, driver can conveniently realize correct recognition function by switch.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
