And described radio frequency reader adopts the DF transmitter module, and its frequency of operation is 315MHz, adopts the SAW resonator frequency stabilization, and frequency stability is high.Be particularly suitable for multiple one and receive wireless remote control and data transmission system; The DF data module has the operating voltage range 3～12V of broad; Transmission frequency is constant basically when change in voltage, and its transmitting range becomes along with the rising of voltage greatly, and remote control distance is advisable at leaving from station 30～50m.
And; Described radio-frequency card adopts the DF module, and the input end antenna of this module has frequency selection network, and output terminal has the wave mode treatment circuit; Can reduce the interference of noise signal to this system; This module self radiation is minimum, netted ground connection Copper Foil is installed at the module back side, has reduced that self electromagnetic signal is leaked and the influence of undesired signal.
And, comprise manual operating key on the described Keyboard Control module, when some special and fortuitous events occurring; The driver presses the control button, can force the program of calling out the stops is revised, or make bus send some special sound information; After fortuitous event is removed; Bus receives new platform signal, and after the coding checking, program can be recovered automatic operation again.
And the MP3 module that described voice broadcast module is special needn't connect power amplifier again and can drive loudspeaker; Extrapolation USB flash disk or SD card get final product, and control also simply, can play the high tone quality voice and needn't connect power amplifier again and can drive loudspeaker; Extrapolation USB flash disk or SD card get final product, and control also simply, can play the high tone quality voice.
Advantage of the present invention and good effect are:
1, process output channel of the present invention adopts photoelectricity and the dual isolation of relay; To eliminate interference from the scene; Use isolating transformer and stabilized voltage supply, with the various interference of blocking-up, in analog input channel from power supply; Adopt photoelectric isolation technology, and utilized digital filtering that the interference to signal in on-the-spot and the transmission course is cut to bone.
2, system of the present invention adopts distributed topology and intelligent object, and the hardware of system is disperseed, and dangerous the dispersion, has improved the antijamming capability and the reliability of system.
3, the present invention is received by radio frequency reader and is installed in the coded signal that the radio-frequency card on the platform of bus stop sends; Discern, and control vehicle-mounted broadcast system and call out the stops, realized station truly identification and automatic broadcasting automatically; Because in the identification and the process of calling out the stops; Do not need manual intervention, reduced driver's operation, improved the security of vehicle operating simultaneously yet.
