Next, the operation of the present invention will be explained in detail with reference to FIGS. 2 to 7.

FIG. 3 is a flowchart showing a processing operation for switching receivers depending on the signal format when a transmission is received from an external telephone to this system.

First, a call is made from an external telephone 8 to a telephone (8 in the block diagram of FIG. 2) connected to this system in one's own office. At step SO in the flowchart of FIG. 3, the line is switched by the 10 NCU in the block diagram of FIG. 2 so that the signal flows to the personal computer. In step Sl, the type of signal sent by the receiver switching control device in block diagram 11 of FIG. Connect to a machine or connect to 16 acoustic receivers, 1
Switch whether to connect to the voice recognition receiver of 7. If you have switched to a push-button receiver, go to step ■)l in the flowchart in Figure 1. When switching to a dial pulse type receiver, the process goes to step Di in the flowchart of FIG. If you have switched to an acoustic receiver, go to step TI in the flowchart in FIG. 6 (if you have switched to a voice recognition receiver, go to step Vl in the flowchart in FIG. 7).

FIG. 4 is a flowchart showing the data processing operation of the computer I when receiving data from a push-button receiver.

The operation from step P2 in FIG. 4 will be explained.

To enter the numbers, enter the number on the push button as it is, and at the end of one number, press the country to differentiate. For example, the command is determined to correspond to a two-digit number, and an eye is input first to distinguish it from the data number. If you wish to disconnect the communication, please input the following.

In step P2 of the flowchart in FIG. 4, the receiver 2 in the block diagram of FIG. 2 receives and determines whether the transmitted signal is a signal. If it is a ward, the flag is set to 1 in step P7 and the next signal is waited for. If not, step P
Similarly, it is determined whether the signal is for the exit to 3.

If it is a country, check whether the flag is 1 in step P8. If it is a flag month, it means that a return has been input, and the process goes to step PLO, disconnects the line, and sets the flag to 0 for the next reception at step pH, and ends the process. If the flag is not 1 in step P8, it is an end signal for one item of data, so the process passes through step P9 and waits for the next input.

If it is not a country in step P3, go to step P4 and check whether the flag is O. Since the flag is 0, it means inputting a number of data, so the process goes to step P5 and stores it as a number in the personal computer, clears the flag in step P6, and waits for the next signal.

If the flag is not 0 in step P4, it is a command input, and in step P12 it is checked whether the flag is 1 or 2.

In the case of the flag, the process goes to step PI5, which is the signal immediately after the prisoner is input, and is stored in the personal computer as one character of the two-digit number of the command, and in step P16, the flag is set to 2 and the next signal is waited for. The fact that the flag is not 1 in step P12 means that it is the second digit of the command, and step P1
3 and the first digit to determine the corresponding command. In step P14, processing is executed on the personal computer according to the command. Next, the process goes to step P6, clears the flag, and waits for the next signal.

FIG. 5 is a flowchart showing the data processing operation of the computer 1 in the case of reception by a dial pulse type receiver.

The operations from step D2 in FIG. 5 will be explained.

Here, to input numbers, press dial O and the desired number, and press 2.
It shall be expressed in digits. The end of one number is distinguished by turning the dial l. Commands range from 20 to 99
Decide on the two-digit numbers up to (. Also decide on the command to disconnect communication among the commands.)

In step D2 of the flowchart of FIG. 5, the state of the flag is checked. If the flag is O, go to step D3 and send a signal.
Check whether the number is dial O. If the dial is O, go to step Dll, set the flag to 1, and wait for the next signal. If the dial is other than 0, the process goes to step D4 and it is determined whether the dial is 1 or not.

If it is dial l, the process goes to step D5, and since this is the end signal for one item of data input, the flag is set to 0 in step D6, and the process waits for the next signal. If the dial is other than 1 in step D4, go to step D7. 1 of 2 digits of command
Store it as the character, set the flag to 2, and wait for the next signal.

If the flag is 1 in step D2, it is a numerical value input, so it is stored as a data input numerical value in step D9, the flag is set to 0 in step DIO, and the process waits for the next signal.

If the flag is 2 in step D2, it is the second character of the command, and the command is analyzed in step D12 along with the first character. In step D13, processing is executed on the personal computer according to the command. In step DI4, it is determined whether the command is a communication disconnection command, and if so, the process proceeds to step D16, where the line is disconnected and the process ends. Step D1
If it is not a line disconnection command in step D15, the flag is cleared and the next signal is waited for.

FIG. 6 is a flowchart showing the data processing operation of the computer I when receiving data from an acoustic receiver.

The operations from step T2 in FIG. 6 will be explained.

Here, it is assumed that the speaker has a transmitter that can transmit at least 10 different frequencies.

The 10 types of signals are signal O to signal 9, and the input of numbers is performed assuming that after transmitting signal 0, signals O to signal 9 correspond to the numerical values 0 to 9, respectively. The end of one numerical value is distinguished by transmitting a signal 1.

The command is determined in advance to correspond to a combination of two signals, one from signal 2 to signal 9 and one from signal 0 to signal 9. Also, in the case of a transmitter that cannot transmit 10 different frequencies, use a method to control 10 different transmission times, as shown in the flowchart in Figure 6. In step T2, check the state of the flag. If the flag is 0, go to step T3 and check whether the signal is signal O. If the signal is 0, go to step Tll and set the flag to 1 and wait for the next signal. Signal If it is other than 0, go to step T4 and judge whether the signal is 1. If the signal is 1, go to step T5 and set the flag to 0 because it is the end signal for one item of data input.
If the signal is other than 1 at step T4, the process goes to step T7. Store it as the first character of the two digits of the command, set the flag to 2, and wait for the next signal.

If the flag is 1 in step T2, it is a numerical value input, so it is stored as a data input numerical value in step T9, and the flag is set to 0 in step TIO before waiting for the next signal.

If the flag is 2 in step T2, it is the second character of the command, and the command is analyzed together with the first character in step T12. In step TI3, processing is executed on the personal computer according to the command. In step 'r14, it is determined whether the command is a communication disconnection command, and if so, the process goes to step T1'6 to disconnect the line and end the process. If it is not a line disconnection command in step T14, step T
Go to 15, clear the flag and wait for the next signal.

FIG. 7 is a flowchart showing the data processing operation of the computer 1 when receiving data from the speech recognition device.

The operation starting from step V2 in FIG. 7 will be explained.

Here, the speaker needs to decide in advance to be able to distinguish between a numerical value, an end command for one item, and each command.

All you have to do is say it over the phone. In addition, a command to disconnect communication is also determined among the commands.

In step V1, the audio signal is recognized and analyzed.

In step V2, the analysis result is determined, and if it is a numerical value, the process goes to step v3, where it is stored as a data input numerical value and waits for the next signal.

In step v4, it is processed as the end of the numerical value of one item of data input, and the process waits for the next signal.

In step v5, if the command is to disconnect the line, the process goes to step V7, disconnects the line, and ends the process.

If the command is not a line disconnection command in step v5, processing is executed on the personal computer according to the command in step v6, and the process waits for the next signal again.

〔Effect of the invention〕

As explained above, according to the transmission system of the present invention, it has become possible to access a personal computer in one's office or the like from an external telephone.
