DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail with reference to FIGS. 1 to 4. FIG. 1 is a block diagram of a handset equipped with an embodiment of the voice guidance device of the present invention. Incidentally, since the base unit can have the same configuration as the conventional one, a description of its configuration and operation will be omitted.

In FIG. 1, a receiving circuit 3 and a transmitting circuit 5
An antenna 1 for performing wireless communication with the base unit is commonly connected to the base unit, and further connected so that a microcomputer 11 that controls the entire slave unit can send and receive control signals to and from the receiving circuit 3 and the transmitting circuit 5 and control data. has been done.

[0008] The receiving circuit 3 is also connected to an out-of-range detecting section 7 that detects when the slave unit has moved out of the communication range with the base unit.
Furthermore, it is connected to the receiver R via an analog switch ASW2 and an amplifier 21, which are opened and closed under the control of the microcomputer 11. The transmitting circuit 5 is connected to the transmitter T.

[0009] An out-of-range detection section 7 is connected to the microcomputer 11 so as to be able to notify that the slave unit has left the communication range. Furthermore, the microcomputer 11 is connected to the voice guidance section 9 so as to be able to instruct generation of voice guidance. The voice guidance section 9 is an analog switch ASW that opens and closes under the control of the microcomputer 11.
1 to the amplifier 21.

A storage device (ID ROM) 13 in which the identification number of this slave device is stored in advance is connected to the microcomputer 11 so that this identification number can be sent and received. Furthermore, a key matrix 15 is connected to the microcomputer 11 so that key data such as dial data can be input.

A battery E1 for driving the slave unit is connected to the microcomputer 11 via a regulator 19. Furthermore, the battery E1 has voltage dividing resistors R1 and R2
is connected to the voltage detection section 17 via the voltage detection section 17.
is connected to the microcomputer 11.

The operation of the slave device shown in FIG. 1 will be explained. When control data such as dial data is input using the key matrix 15, the data is input to the microcomputer 11 together with the identification number from the ID ROM 13. Thereupon, the control data and identification number undergo predetermined data processing, are output to the transmitting circuit 5, and are transmitted from the antenna 1 to the base unit. During a call, a call signal from the transmitter T is transmitted from the antenna 1 to the base unit.

Control data and call signals coming from the base unit are input to the receiving circuit 3 via the antenna 1. The call signal is then input to the receiver R via the analog switch ASW2 and the amplifier 21. The control data is input from the receiving circuit 3 to the microcomputer 11, where it is subjected to predetermined data processing.

The receiving circuit 3 also inputs a signal indicating the level of the carrier wave received from the base unit to the out-of-service area detection unit 7. When the handset moves away from the base unit to the limit of the communication range (set in the out-of-range detection unit 7 as a first reference voltage V1, which will be described later), the out-of-range detection unit 7 outputs a first signal indicating this. The detection signal is sent to the microcomputer 11. Within the microcomputer 11, this first detection signal is subjected to predetermined processing, and a calling area guidance instruction signal is generated and input to the voice guidance section 9. At the same time, the microcomputer 11 sends a first switching control signal to the analog switch ASW1. As a result, the movable contact a of the analog switch ASW1 is switched from the fixed contact b to the fixed contact c, and the voice guidance section 9 sends out a guidance message such as "You are out of service area, please move closer to the base unit" that has been stored in the voice guidance section 9 in advance. is sent to the receiver R via the analog switch ASW1.

Furthermore, when the handset moves away from the base unit to a point where it is completely impossible to make a call (this is set in the out-of-range detection section 7 as a second reference voltage V2, which will be described later), the out-of-range detection section 7 detects that point. The second detection signal indicating
Send to. The microcomputer 11 performs predetermined processing on this second detection signal, and sends a second switching control signal to the analog switch ASW2. As a result, the movable contact d of the analog switch ASW2 is switched from the fixed contact e to the fixed contact f, and the signal path connecting the receiving circuit 3 and the receiver R is cut off, making it completely impossible to receive calls.

Further, the power supply voltage from the battery E1, which has been divided by the resistors R1 and R2, is input to the voltage detection section 17.
Here, it is compared with a preset reference voltage. When it is detected that the power supply voltage has fallen below the reference voltage, the voltage detection section 17 sends a voltage detection signal indicating this to the microcomputer 11. The microcomputer 11 performs predetermined processing on this voltage detection signal and sends a voltage guidance instruction signal to the voice guidance section 9. Along with this, the microcomputer 11 also switches to the analog switch ASW1.
A signal similar to the first control signal is sent to the first control signal. As a result, the movable contact a of the analog switch ASW1 is switched from the fixed contact b to the fixed contact c, and the voice guidance section 9 sends a guidance message such as "no battery" stored in the voice guidance section 9 to the handset via the analog switch ASW1. Send to R.

Next, the operation of detecting when the handset is out of communication range will be explained in detail with reference to the block diagram of the receiving circuit 3 and out-of-range detection section 7 shown in FIG. In FIG. 2, the receiving circuit 3 includes a high frequency amplifier 31, a local oscillator 33, an intermediate frequency amplifier 35,
It includes a detector 37 and a filter 39. Further, the out-of-range detection section 7 includes a capacitor C1, a filter 71, an attenuator ATT, a buffer amplifier 73, a half-wave rectifier circuit 75 consisting of a capacitor C2 and diodes D1 and D2, and a resistor R3.
and a smoothing circuit 77 consisting of a capacitor C3 and a comparator 79.
, 81.

A carrier wave modulated by a speech signal or a control data signal is transmitted from the base unit via the antenna 1 to the receiving circuit 3.
When the carrier wave arrives, it is amplified by a high frequency amplifier 31 and mixed with a local oscillation signal from a local oscillator 33 to become an intermediate frequency signal. A detector 37 extracts an audio intermediate frequency signal from the intermediate frequency signal amplified by the intermediate frequency amplifier 35 . Then, a 3 kHz filter 39 extracts an audio signal (call signal or control data signal) from the audio intermediate frequency signal.

On the other hand, the noise component contained in the audio intermediate frequency signal extracted by the detector 37 is input to the filter 71 via the capacitor C1, where the noise component is detected at 10 to 20 KHz.
Noise components in the frequency band are extracted. Filter 71
The noise component that has passed through is moderately attenuated by the attenuator ATT, and then sent to the half-wave rectifier circuit 75 via the buffer amplifier 73.
It is entered in . Here, the half-wave rectified noise component is smoothed by a smoothing circuit 77 and input to one input terminal of each of the comparators 79 and 81.

A first reference voltage V1 corresponding to the closest communication range between the slave unit and the base unit is input to the other input terminal of the comparator 79, and the voltage level of the noise component is equal to the first reference voltage. It is compared with V1. When the slave unit gradually moves away from the master unit and the voltage level of the noise component becomes higher than the first reference voltage V1, the comparator 79 sends a first detection signal indicating this to the microcomputer 11 of FIG. 1.

In addition, a second reference voltage V2 corresponding to a distance at which communication between the slave unit and the base unit is completely impossible is input to the comparator 81 at the other input terminal, so that the voltage level of the noise component is at the second level. 2 is compared with the reference voltage V2. When the slave unit is far away from the base unit and the voltage level of the noise component becomes higher than the second reference voltage V2, the comparator 8
1 sends a second detection signal indicating this to the microcomputer 11 in FIG.

The above comparison operation will be further explained with reference to FIG. FIG. 3 shows the signal levels of the audio signal and noise components extracted by the receiving circuit 3. The signal level of the voice signal is almost constant within the communication range. When the slave unit moves away from the base unit to the limit of the communication range, the noise component increases (reference voltage V1), and the out-of-range detection unit 7 sends a first detection signal to the microcomputer 11. Furthermore, when the handset moves away to a distance where it is completely impossible to communicate with the base unit, the audio signal suddenly decreases and the noise component suddenly increases (reference voltage V2). Then, the out-of-service detection section 7 sends a second detection signal to the microcomputer 11.

Next, the configuration and operation of the slave microcomputer 11 will be explained in detail with reference to FIG. In FIG. 4, the microcomputer 11 recognizes control data.
It includes a control section 111, a voice control section 113, an analog switch control section 115, an ID code recognition section 117, and a key matrix recognition section 119.

Control data transmitted and received between the base unit and the slave unit via the antenna 1, the receiving circuit 3, and the transmitting circuit 5 is transmitted and received by the control data recognition/control unit 11 of the microcomputer 11.

11 and undergoes predetermined data processing.

As explained with reference to FIG. 2, the noise component contained in the audio intermediate frequency signal is input from the reception circuit 3 to the out-of-service area detection section 7. When the handset moves away from the base unit to the limit of the communication range, a first detection signal is input from the out-of-range detection unit 7 to the voice control unit 113 of the microcomputer 11. As a result, the voice control section 113 sends a guidance instruction signal to the voice guidance section 9, and further sends a switching control signal to the analog switch control section 115. In response to this, the analog switch control section 115
A first switching control signal is sent to the analog switch ASW1 in the figure. As a result, the movable contact a of the analog switch ASW1 is switched from the fixed contact b to the fixed contact c, and the voice guidance section 9 sends out a guidance message such as "You are out of service area, please move closer to the base unit" that has been stored in the voice guidance section 9 in advance. is sent to the receiver R via the analog switch ASW1.

[0026] Furthermore, when the slave unit moves away from the base unit to a distance where it is completely impossible to communicate with the base unit, a second detection signal is input from the out-of-range detection unit 7 to the analog switch control unit 115. In response to this, the analog switch control section 115 sends a second switching control signal to the analog switch ASW2 in FIG. As a result, the movable contact d of the analog switch ASW2 is switched from the fixed contact e to the fixed contact f, cutting off the signal path connecting the receiving circuit 3 and the receiver R, making it completely impossible to receive calls.

Next, when the voltage detecting section 17 in FIG. Send to. As a result, the voice control section 11
3 sends a guidance instruction signal to the audio guidance section 9, and further sends a switching control command to the analog switch control section 115. In response to this, the analog switch control section 115 sends a signal similar to the first switching control signal to the analog switch ASW1. This allows analog switch A
The movable contact a of SW1 is switched from the fixed contact b to the fixed contact c, and the voice guidance section 9 sends out a guidance message such as "no battery" stored in advance to the receiver R via the analog switch ASW1. do.

[0028] For information on the various functions provided on the handset,
The signals corresponding to the functions are shown in the key matrix 15 in Figure 1.
When input from , it is recognized by the key matrix recognition unit 119 of the microcomputer 11 and input to the control data recognition/control unit 111 . Then, the control data recognition/control unit 111 sends a control command to the voice control unit 113. As a result, the voice control section 113 sends a guidance instruction signal to the voice guidance section 9, and further sends a switching control signal to the analog switch control section 115. In response to this, the analog switch control unit 115 switches the analog switch ASW1.
A signal similar to the first switching control signal is sent to the first switching control signal. As a result, the movable contact a of the analog switch ASW1 is switched from the fixed contact b to the fixed contact c, and the voice guidance section 9 sends a guidance message corresponding to the signal from the key matrix 15 to the receiver R via the analog switch ASW1.

The controller 111 performs predetermined processing. As a result, a control command is sent to the analog switch control section 115. In response to this, the analog switch control section 115 sends a signal similar to the second switching control signal to the analog switch ASW2. As a result, the movable contact d of the analog switch ASW2 is switched from the fixed contact e to the fixed contact f, cutting off the signal path connecting the receiving circuit 3 and the receiver R, making it completely impossible to receive calls.
