(1) radio frequency input circuit: receive the radiofrequency signal of sending the base station and carry out that height is put, frequency conversion, in put, processing such as demodulation, low-pass filtering, amplitude limit.The digital signal of its demodulation is sent to decoding circuit.
(2) decoding circuit: synchronization character is decoded, extracted to the digital signal to input.Its code plug-in comprises this machine address and function information.
(3) the auxiliary circuit of supporting: provide the support of complete machine each several part power supply, functions such as function key I/O support.
(4) display circuit: show the information that output receives, display system operating state etc.
(5) data interface circuit: with external equipment such as PC, the interface of other intelligent receiving device.When the central processing unit unit adopts bi-processor architecture, also bear the exchanges data between the processor.
(6) central processing unit circuit: various calculating, generation control signal, various input and output control or the like are controlled, finished to complete machine control and treatment core, the management of being responsible for system resource.Central processor unit can adopt uniprocessor or bi-processor architecture.Adopting dual processor to be convenient to the design of product modular cordwood system type realizes.
(7) storage circuit: program, data storing.
(8) sensor interface circuitry: can connect multiple sensors, the temperature of perception environment of living in, humidity, smog, parameters such as mobile, these parameters are foundations of system program operation.

(10) digital control circuit: the control signal that central processor unit is generated drives output.
(11) speech conversion circuit: the requirement by central processor unit changes Word message into voice messaging, and with converted output signal output after D/A, amplification drive.
(12) loud speaker: pronunciation output.
With reference to Fig. 2, after the radiofrequency signal of being sent by the radio call base station is received by radio frequency input circuit 1, obtain the digital signal of serial in its demodulator output.This digital signal is the input signal of decoding circuit 2.If decoding circuit 2 is identical with this machine address of receiving system from the address that these digital signal decodings go out, receiving system with regard to continue to receive thereafter information and by central processing circuit 6 carry out follow-up storage demonstration, control signal generates processing such as output, otherwise ignores information thereafter.Keep the wait accepting state.
The information that intelligent radio paging terminal device receives is divided into paging information and control command, and central processing circuit 6 is handled them by different flow processs respectively.
A) handling process of paging information
For with digital code or the paging information formed with the character string phrase, intelligent radio paging terminal device receives the back and earlier it is stored in the storage circuit 7 by central processing circuit 6.Basis operating state at that time is provided with the decision way of output then.
The intelligent radio paging terminal has the mode of two kinds of output paging informations, and a kind of is to show output, and another kind is a voice output.Adopt any output, depend on the working state of system setting, also depend on the input of sensing port.
Show that output is to show the information of receiving with code or character on display screen, similar with traditional paging receiver.Take out the direct information display circuit 4 that will show by central processing circuit 6 from storage circuit 7 in this case and show output.
Voice output is to utilize the TTS function of intelligent radio paging terminal, and the character information of receiving is changed into voice, then by loud speaker pronunciation output.Take out direct information TTS (voice) change-over circuit 11 of the output of will pronouncing by central processing circuit 6 from storage circuit 7 in this case, finish Word message by it and after conversion, D/A, the amplification of voice messaging drives, be sent to loud speaker 12 and export.
And for code signal, then directly output is corresponding with this code, is stored in the voice signal in the memory of intelligent radio paging terminal in advance.
B) handling process of control command
The intelligent radio paging terminal system receives control command by the radio call channel.The character string that control command is taken the lead by spcial character is formed.Each bar instruction is divided into instruction name and order parameter two parts, and an instruction can have a plurality of order parameters, also can not have order parameter.Corresponding response is explained and made to instruction by the CPU of system.
Control command is divided into two big classes, and a class is the instruction that the intelligent radio paging terminal device self working state is provided with the control of adjustment; Another kind of is the instruction that the requirement intelligent radio paging terminal device generates the output control signal.
After receiving control command, central processing circuit 6 is recognition instruction classification and it is stored in storage circuit 7 puts on record at first, then instruction is made an explanation and operates accordingly according to command request.
For first kind control command, central processing circuit 6 carries out corresponding setting and adjustment by its requirement to the operating state of intelligent radio paging terminal, such as changing workflow, changes show state, change the voice output tone, the opening that changes control port is closed or the like.
For the second class control command, central processing circuit 6 generates the control signal of control figure equipment and the control signal of control analog machine according to instructing name and order parameter and sensing input parameter to call corresponding program.The control signal of control analog machine is sent to analog control circuit 9 after the D/A conversion is amplified, the control signal of control figure control appliance then directly is sent to digital control circuit 10.
The intelligent radio paging terminal device that the present invention proposes, its CPU can adopt the dual micro processor structure, as shown in Figure 3.Under this structure, microprocessor Mp1 mainly is responsible for the signal reception and shows output, and microprocessor up
2Main responsible control and TTS voice output and transducing signal are handled.Two microprocessors are through the data-interface swap data.This structure is beneficial to the modularization of product and separates cordwood system type design realization.Two building block modules can be worked relatively independent or discretely.As shown in Figure 4.
