Below describe the words sign indicating number remote-control communication device in the system of the present invention, the description of its course of work will help further understanding of the present invention.
At first, with the IBM-PC machine be the communication mode of example explanation words sign indicating number remote-control communication device and computer:
The RS-232C interface of IBM-PC machine is to be the asynchronous communication adapter UART of core formation standard with programmable INS8250, and it makes PC have the ability to carry out communication with the equipment with standard RS-232C interface.
The important function of RS-232C interface is that the parallel data of CPU output is converted to serial data output, and also the serial data that receives is converted to parallel data and gives CPU and handle.
When two PC telecommunications, usual way is that (referring to Fig. 3) need add the Modem(modulator-demodulator in the RS-232C of every PC interface), with " 0 " and " 1 " voltage transitions of RS-232C interface output is that the signal of different frequency is defeated in phone line, and the input of same RS-232C interface is the conversion of signals of different frequency " 0 " and " 1 " signal accordingly by Modem also.Every PC is by visiting or control the communication that realizes between two places to the UART among the RS-232C.That is to say, between the PC or between PC and the special-shaped machine, all telephone wires (speech channel) that utilizes are as communication link, special-purpose member Modem must be arranged therebetween.
Words sign indicating numbers remote-control communication device realize between the PC exactly or PC and special-shaped machine between, utilize telephone wire (speech channel) as communication medium, the novel features of the master data of utilizing that the conduct of phone words sign indicating number communicates by letter, referring to Fig. 4.Words sign indicating number remote-control communication device has replaced the MODEM among Fig. 3, receives from the audio code on the telephone wire, and converts the binary code that computer receives to.
The department of computer science that comprises words sign indicating number remote-control communication device in the dashed rectangle of Fig. 4 is referred to as words screen PC, and referring to Fig. 1 as can be known, this system just can constitute above-described a kind of user terminal by telephone set directly being received words sign indicating number remote-control communication device.
Referring now to Fig. 5 and Fig. 6, the circuit structure of words sign indicating number remote-control communication device is described and talks about the sign indicating number receiving course.See Fig. 5 earlier, holding wire DTR among the figure and RI are respectively the holding wires 16 and 17 among Fig. 1, they directly with the RS-232C interface in the DTR(data terminal ready of UART) with the RI(bell signal) port is connected, so represents respectively with DTR and RI at this.Words sign indicating number remote-control communication device is only undertaken by two signal line of RS-232C with communicating by letter of computer.
Holding wire RI is generally ring (RI) signal port, i.e. (17 among Fig. 1) here then is the unified code signal port of ring and phone words sign indicating number;
Computer is judged the state of RI by reading the RI mode bit of UART.For INS8250 is the UART of core, and CPU only need read its relevant register value with the RI mode bit (as: the position 6(RI of Modem status register)).
Holding wire DTR is generally the signal port (16 among Fig. 1) of " data terminal ready (DTR) ".
DTR is sent to the carry input S of shift register 56 on the one hand as the displacement control signal after Transistor-Transistor Logic level translation circuit 58 carries out level translation; Control signal as switch 52 affacts switch 52 on the other hand.We can say that also DTR is the control signal of switch 52, is again the displacement control signal of shift register 56.
Computer reaches to switch 52 and to the control of shift register 56 by the DTR mode bit of control UART.For INS8250 is the UART of core, and CPU only need control its register value relevant with the DTR mode bit, reaches to switch 52 and to the control of shift register 56.
That is to say that computer has just been realized the communication of these words sign indicating number remote-control communication device by the related register of visit or control UART.
Words sign indicating number receiving course is as follows:
Referring to Fig. 6.Program at first enters the B1 frame DIR is held reset (at this moment, the DTR among Fig. 5 is a low level, and shift register 56 is a high level, and switch 52 is in non operating state, and speech channel 4 is connected by the branch road K1 and the phone P of switch 52), speech channel and closing of the circuit.Whether then, enter process block B2, differentiating has bell signal, and when not having the words sign indicating number, program is returned the B1 frame; When words sign indicating numbers (RI among Fig. 5 presents the high level of " 1 "), program enters the process that frame B3 reads to talk about sign indicating number: computer is to the reset of DTR port, set ... make port DTR form one group of sequence signal, this sequence signal is controlled shift register 56 displacements after Transistor-Transistor Logic level translation circuit 58 carries out level translation; Frame B3 reads to talk about coded program and finishes to enter process block B4 behind the back (shift register 56 is returned " 0 "), differentiates whether the words sign indicating number of being read with " 8421 " expression is " 1111 ".If not " 1111 ", the words sign indicating number of program phone P in frame B5(Fig. 5, its words sign indicating number is " 8421 " sign indicating number), return the B1 frame; If the words sign indicating number is " 1111 ", what illustrate that computer receives is that (bell signal is detected by the ringing detector among Fig. 5 59 for ring from speech channel, by with door 57, behind level-conversion circuit EIA conversion level to the port RI of Fig. 5) signal, program enters frame B6 and holds set (at this moment DIR, the DTR of Fig. 5 is a high level, make switch 52 work behind Transistor-Transistor Logic level translation circuit 58, branch road KO connects, and this equals to respond ring, connect speech channel), connect speech channel.Program enters waits for the process block B7 that receives from speech channel phone words sign indicating number: whether have bell signal, when not having the words sign indicating number, return B1 if declaring port RI; When words sign indicating numbers (RI among Fig. 5 presents the high level of " 1 "), program enters B8 and reads words sign indicating number process, it is just the same that its process and B3 read the process of ringing code, just the words sign indicating number of being read with " 8421 " expression " 0001,0010 ...; 1100 " in any, the words sign indicating number of being read is sent into B9 words sign indicating number reception buffering area, receive the words sign indicating number and finish, return the B1 wait and receive ring next time and phone words sign indicating number ...
The principle that the words sign indicating number of shift register 56 enters computer more than has been described.Obviously, no matter what what said sign indicating number shift register 56 deposits, its processing procedure that enters computer is duplicate with the processing procedure that " ring words sign indicating number " enters computer.
Now, be described as follows with regard to the speech channel phone words yard process that enters shift register 56:
Referring to Fig. 5.No matter phone words sign indicating number is from the phone words sign indicating number of the phone P that joins with K1, still from the telephone number of speech channel 4; Or from the bell signal of speech channel, all decoded through decoder 53.Except that parallel the delivering to four inputs in the right side of shift register 56 of " 8421 " words sign indicating number that will produce, also produce control signal C, this signal is sent " 8421 " words sign indicating number into shift register 56, simultaneously, with first place (the first from left position) set of shift register 56, treat that signal C finishes after, the first place of shift register 56 is " 1 ", after door 55,57 and level translation, to port RI.Fig. 6 process block B2 declares the high level of RI for " 1 ", promptly enters the said yard process of reading as Fig. 6 frame B3.
So far, the reception principle explanation that Fig. 5 " ring " and phone words sign indicating number is unified finishes.
Receive principle according to this, it only takies two signal line of RS-232: one is ring index signal line RI, and it becomes " ring " words sign indicating number, words sign indicating number incoming line that telephone number is unified.Another is " ready " holding wire DTR, and it promptly is a words sign indicating number input control line, is again the control line of off-hook, on-hook switch 52 simultaneously.Described characteristics make other parts (as MODEM, FAX etc.) of public RI and DTR holding wire, same RS-232 interface that can shared computer.
A words sign indicating numbers remote-control communication device directly links to each other with the RS-232C interface of standard, can be directly works in the visit of computer, under controlling, and therefore, has very big flexibility and portability, is adapted to various types.
Words sign indicating numbers remote-control communication device has been owing to adopted aforesaid words yard reception technique, and it makes telephone set become terminating machine with the minimum configuration of compunication; Make phone words key become the minimum instruction collection of remote control access computer.
Utilize telephone network as communication medium, utilize the basic agreement of words sign indicating number (phone words sign indicating number) as communication, and control work between each functional part by words sign indicating numbers remote-control communication device, make computer and each functional part be combined into a new system with preferred plan, feasible each Terminal Type that adds this system's net, except that keeping original function, system gives its new function, has opened up new application.
The following describes automatic information service system is how to carry out various services.
The automatic information service station can become practical wired automatic information service station alone among Fig. 1, simultaneously again can with wireless transmission 15 or other air station of Fig. 1, for example the wireless paging station constitutes wired, wireless messages service system.
With an existing wireless paging station is example:
