Three, central processor unit: can be single-chip microcomputer, can be other programmable microprocessor also, is used for the coordinated operation of control system, and the core CPU module can be used disposable type, as long as enough input/output port and address wire, data wire can be provided.
Four, information broadcast receiving element: bare bones is the paging module or the element of beep-pager module: FLEX or POCSAG standard, in order to the public or specific information of big capacity of paging receiving platform transmission.Selectable unit is wireless colony net/conventional net receiver module or FM/AM radio station receiver module, in order to receive the information that wireless colony net, conventional net, FM checking station or AM broadcasting station send.
The operation principle of the embodiment that provides in the accompanying drawing 2,3 is as follows: by DLL (dynamic link library) the FLEX receiver is provided with, comprises address code, power saving cycle, some parameters such as receiving phase.Parameter re-powers after setting up, and CPU just can pass through I
2The C bus method is from E
2PROM passes through I again for reading configuration information
2The C bus is input in the decoder, just is in normal accepting state after decoder harvests data and verification correctly, and the decoder initialization is successful, and carries out work according to the parameter of setting, otherwise will reinitialize decoder.The RF part mainly is the original modulated digital information of output behind the frequency modulation information via double conversion of high frequency (as 280MHZ) and the frequency discrimination.Decoder compares and treats the digital information that transmits, and just loses if not the information of oneself, is then to notify CPU that data are taken away, and CPU just sends to output unit after receiving complete information.
FLEX contains the unit RF unit, twice mixing, frequency discrimination and decoded portion among Fig. 3.The information coded modulation that paging centers at first sends desire is launched by transmitter to the high frequency item of 15 frequency ranges or 28 frequency ranges.Aerial high-frequency signal is delivered to RF and is partly carried out processing and amplifying, with the first intermediate frequency mixing after antenna receives, carry out mixing grain husk the second time with second intermediate-freuqncy signal again, the output that produces 455KHZ is handled through frequency discriminator again, produce audio frequency output (0-3KHZ),, produce digital signal by decoder output.This digital signal is through D
3(IC) level conversion, each signal after the level conversion and single-chip microcomputer D
2I/O link to each other, by single-chip microcomputer the digital information of input is carried out the secondary decoding again, translate into the Chinese/English/digital information that has defined, deliver to LCD display and can do other further processing.
