Abstract

PURPOSE:To detect assuredly a fact that the own station is called and to attain the aural identification of a group number for a personal radio device which identifies sound by the group number, by generating a ringing tone of a column of the scale when the own station is called. CONSTITUTION:When the number of own station is transmitted from the station of the remote side, a group number is called out of an automatic identification code demodulator 3 and supplied to a control part 4'. A ringing tone of a column of the scale is produced three times from the part 4'. Thus it is known assuredly that a call is given from the station of the remote side. In case two group numbers are desired at a time, a melody is produced in response to each group number. Thus it is possible to attain the aural identification of group numbers.

Description

[Detailed Description of the Invention] (Field of Application) Dear BA number, this is related to a personal wireless device, in particular, to identify the group number (hereinafter referred to as the group number) by sound when called by the other party. Regarding personal radio equipment.

(background) FIG. 1 shows a block diagram of a conventional personal radio.

In the figure, 1 is an antenna, 2 is a receiving circuit, 3 is an automatic identification code demodulator for reading out the group number from the signal received by the receiving circuit 2, and 4 is a received group number input in advance. A control unit 5 includes a microprocessor (hereinafter abbreviated as a microcomputer), etc., which compares and determines whether or not the numbers are the same as the Gunso-go, and when they are the same, outputs a signal to a call lamp drive circuit and a low frequency amplifier, which will be described later. A low frequency amplifier, 6 a speaker, 7 a call lamp drive circuit, and 8 a call pump. Note that the receiving circuit section 2 and the automatic identification code demodulator 3 can be the same well-known circuits used in car telephones and the like.

Next, the reception operation of the personal radio device having such a configuration will be explained.

The signal of the partner station captured by the antenna 1 is received by the receiving circuit section 2, and the automatic identification code converter 3 reads out the group number transmitted by the partner station. Since the group number of the own station is stored in advance in the control unit 4, the control unit 4 determines whether the received number matches the group number of the own station, as shown in the flowchart of FIG. Decide whether or not you did it. As a result, when it is determined that they match, the control section 4 outputs a signal to the call lamp drive circuit 7 and the low frequency amplifier 5.

When a drive signal is input to the call lamp drive circuit 7, the call lamp 8 lights up or blinks. Furthermore, when a signal is input to the low frequency amplifier 5, the speaker 6 produces a monotonous sound. Therefore, the owner of the personal wireless device can know the person who received the call from the other party's station.

However, as mentioned above, with conventional local radios, when receiving a call, the other station calls you, and if the numbers are in the same group, the call lamp lights up or a simple tone notifies you that you have been called. Therefore, there was insufficient certainty that I would know that I had been called. Also, since the group numbers could not be distinguished by sound, there was a drawback that when waiting for two groups at the same time, you could not tell which group number was called without looking at the display. .

(Objective) It is an object of the present invention to eliminate the drawbacks of the prior art described above, to more reliably detect a call from the other station, and to detect which group number in the case of dual waiting. To provide a personal radio device which can distinguish by sound whether someone is called. .

(Generally speaking, the present invention, as shown in Fig. WS3, is a personal radio device having an antenna 1, a receiving circuit section 2, and a self-jjlj discrimination code demodulator 3, in which a 10-key switch for specifying the group number of the own station is used. 9. Means 10 for storing the group number specified by the 10 key switch; Means 11 for comparing the receiving group number subsequently determined by the 11 adjuster 3 with the group number of the own station;
, and means 12 for outputting the fifth order of the group number when the two match.

(Example) An embodiment of the present invention will be described below with reference to FIG.

Figure 4 shows Personal Mu IIi! FIG. 2 is a block diagram showing a part of the tsuki that is related to the present invention.

In the figure, 9 is a 10-key switch for inputting the group number to be received and 10 key switches for specifying the 00 house number, and 4' is a comparison button for checking whether the received group number and the input group number are the same. A control unit including a microprocessor or the like is shown which generates five scale tones, each corresponding to a five-digit group number, at the same time.

Further, symbols other than these indicate the same as or equivalent to those in FIG. 1.

Next, the operation of this embodiment will be explained.

The 10-key switch 9 is for inputting the group number of the own station into the control unit 4, and the 10-key switch 9 allows
The group number of the own station is input into the control unit 4 in advance. Now, when there is a transmission from the partner station, it is received by the antenna 1 and the receiving port part 2, and the group number is read out from the automatic identification code decoder 3, as in the conventional circuit. Then, it is input to the control section 4'.

Next, the operation of the control section 4' will be explained with reference to FIG.

FIG. 5 shows a flowchart for explaining the functions of the control section 4'.

Step 81: It is determined whether the received group number and the own station's group number match. If they match, the process advances to step S2.

Step S2... Input O to an appropriate register r.

Step S3...Subsequently, a one second timer is set. Step S4...The control unit 4', for example, a microcomputer,
0 key switch 9's 10 numbers from 1 to 0, 11
The scale is divided into 1i1. jFor example, 1.2, 3, 4 degrees of 10 key switch 9...9
, 0, 卜, shi, mi, respectively.

Fa,..., shi, mi are expressed in proportion. .

Therefore, a signal corresponding to the scale corresponding to the first digit of the own station's group number is output to the low frequency amplifier 5, and the first digit is "3".
If so, the scale "mi" is output from the speaker 6.

Step S5: It is determined whether the one second timer has completed. If YES, the process advances to the next step S6. Through steps 84 and 85, a "mi" sound is output for one second.

Step S6... A one second timer is set.

Step S7: A signal corresponding to the musical scale corresponding to the second digit of the group number of the own station is output to the low frequency amplifier 5. As a result, if the second digit number is "4", it is called "F".
A scale is output. This tow is output for 1 second in the same way as above.

The same thing is done for the 3rd and 4th digits of the own station's group number. If these 3 and 4 digit numbers are respectively rs'' and [j, the sounds ``n'' and ``u'' are output for 1 second each.

Step 810...A 1 second timer is set again.

Step 811: 6 corresponding to the 5th digit of the group number of your own station
Sui is outputted as 5. If the fifth digit number is [7], the sound "shi" is outputted.

Step 812...A determination is made as to whether or not the one-second paste/imma process has been completed. If yes, next step 8
Proceed to step 13. In step 811 and S12, υ and [sh] sounds are output for one second.

Step S13: 1 is added to register r.

Step 814...It is checked whether r=3. If no, the process returns to step S3 and steps 83 to 813 are repeated again.
It will be the end.

As is clear from the above explanation, according to this embodiment, when the other station transmits its own number,
The ringing tones of the musical scale "G, U, C" are repeated three times. Therefore, since the sound is not as monotonous as in the past, it is possible to know with certainty that the other party has called you.

When waiting for two group numbers at the same time, a melody corresponding to the group number is emitted, so you can easily identify the group number by ear.

It goes without saying that the scale may be sounded by a sounding body such as a buzzer, rather than by a speaker, at a time t6 different from the audio signal.

Further, although the explanation has been omitted, it goes without saying that the control section 4' may cause the call lamp 8 to light up or flash in conjunction with the sound generation.

(Effects) As described above, according to the present invention, it becomes possible to clearly tell that the own station has been called by the musical scale, and the group number can also be distinguished by sound. Therefore, you can clearly know when your own station is being called, and if you have specified multiple group numbers and are on standby, you can distinguish which group number called from among them by the difference in the melody. be.
