BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 shows an embodiment of a mobile phone storage box 1. This shows a production example in the case of installation in a switchboard room of a substation, where a storage box 2 is arranged on an outer wall surface of the switchboard room, an amplifier box 3 is arranged on the inner wall surface, and a speaker 4 is arranged near a protective relay. are doing.

As shown in FIG. 2, the storage box 2 is a box type for opening and closing the front door 2a and taking in and out the mobile phone 5.
It has a closed structure with a roof to prevent rainwater from entering. The reason why the storage box 2 is arranged on the outer wall of the switchboard room is as follows.
Place the mobile phone in a place sufficiently far away from the protective relay etc. so that the protective relay etc. do not malfunction, and at the same time, the on-site supervisor etc. who are entering the switchboard room and working when receiving a call should walk to this place quickly In order to be able to respond. A plurality (for example, eight) of the mobile phones 5 can be stored in the storage box 2 in an aligned state by a hook or a partition (not shown). Also,
In a room 2b (see FIG. 1) formed by partitioning the back side of the storage box 2, a microphone 6 for detecting a ring tone emitted by the mobile phone 5 and a detecting unit 7 for detecting a response radio wave emitted by the mobile phone 5 when receiving a call. Is housed. This storage box 2
The mobile phone is made of, for example, plastic in consideration of the passage of radio waves of the mobile phone, and a power switch 8 and an operation indicator 9 which are also used as a door lock are mounted on the front surface thereof.

The amplifier box 3 includes a power supply unit 1 inside a metal case 10 having a shielding function as shown in FIG.
1, a control relay 12, a message generator 13, and a power amplifier 14 as an output circuit.
When the amplifier box 3 is installed indoors separately from the storage box 2, the semiconductor parts constituting the power supply unit 11 and the like are prevented from being adversely affected by the outside air temperature, and at the same time, they are a source of noise. This is because the power supply unit 11 and the like, which are preferably performed, are housed separately from a mobile phone having an inappropriate shield in order to ensure a good transmission / reception state.

The loudspeaker 4 is mounted near a switchboard on which a site supervisor or the like who is the owner of the mobile phone who enters the room works.

The mobile phone storage box 1 of the present invention is constructed by connecting the storage box 2, the amplifier box 3, and the speaker 4 with necessary wiring. The external connection contacts 15, 15,... On the terminal block used for this wiring correspond to the storage box 2 and the amplifier box 3 in the electric circuit of FIG.
Is shown above the dashed-line frame indicating.

In FIG. 4, a power switch 8 in the storage box 2 switches between starting and stopping the operation of the entire apparatus.
It is provided so as to relay the supply of commercial power (AC) to the power supply unit 11. The power switch 8 is provided with an external output contact 8a as an interlocking contact. This external output contact 8a is used, for example, as a lighting switch of a forgetting prevention light provided at a gate of a substation.

The microphone 6 in the storage box 2 is disposed in a chamber 2b (see FIG. 1) on the back of the storage box 2, and is connected to an external output contact 15 on a terminal block by a shielded wire 6a.

The detection unit 7 in the storage box 2 is disposed in the room 2b (see FIG. 1) on the back of the storage box 2, and detects a radio wave transmitted by the mobile phone to answer the calling station when receiving a call. . The detection unit 7 is composed of a circuit for receiving the frequency of the response radio wave and a circuit for generating a contact output when the frequency of the response radio wave exceeds a certain level, and receives a DC voltage from the power supply unit 11 of the amplifier box 3. Works when The operation indicator lamp 9 is lit by the DC voltage supplied to the detection unit 7 to indicate that the operation is being performed.

A power supply 11 in the amplifier box 3 is connected to a commercial power supply (A) supplied through a power switch 8 of the storage box 2.
A constant DC voltage is generated from C).

The control relay 12 in the amplifier box 3
When the contact output of the detection unit 7 is in the incoming call detection state, the DC voltage generated by the power supply unit 11 is supplied to the message generation unit 13 and the power amplifier 14.

Message generator 1 in amplifier box 3
Reference numeral 3 denotes a predetermined message stored in a semiconductor memory. When a DC voltage is supplied through the control relay 12, the message is reproduced and output for a predetermined number of seconds from the start of the supply.

The power amplifier 9 in the amplifier box 3
It operates when a DC voltage is supplied through the control relay 12. The power amplifier 9 has a built-in input switching circuit and amplifies only the message when the message is generated, and amplifies the output of the microphone 6 when the message disappears. The amplified output is
The signal is supplied to the speaker 4 through the external output terminal 15.
This output is also supplied to an additional terminal 15 ', which is used for adding a speaker when there are many rooms for notification.

Next, an example of actual use of the portable telephone storage box 1 will be described. When a site supervisor enters the switchboard room,
The mobile phone 5 is stored in the storage box 2 and the power switch 8 is turned on. As a result, the power supply unit 11 operates,
Since the DC voltage is supplied to the entire apparatus, the operation indicator 9 is turned on. This lighting confirms that the incoming call transmission function is working and allows the user to enter the switchboard room.

When a call arrives at the stored mobile phone 5, the mobile phone 5 responds to the calling station. Since the response radio wave is detected by the detection unit 7, the control relay 12 operates to supply a DC voltage for operating the message generation unit 13 and the power amplifier 14. Message generator 1
Reference numeral 3 reproduces and outputs a message sound of a fixed length used as an announcement for calling an incoming call immediately after energization. This message sound repeats, for example, twice as shown in FIG. 5, "a mobile phone is ringing. If you are aware, please come to the mobile phone storage box." This message sound is amplified by the power amplifier 14 and played from the speaker 4. Message generator 1
3 stops the reproduction thereafter, so that the power amplifier 14
Amplifies the ringtone of the mobile phone detected by the microphone 6 and outputs it to the speaker 4. The ringtone of the mobile phone 5 is
This is set individually by the owner of the mobile phone, and is, for example, a voice having a different timbre such as "pull-pull", "lulu-lu", "lean", or a melody sound of an arbitrary musical piece.
Therefore, the on-site supervisor who is working first listens to the announcement that evokes the incoming call, then judges from the ringtone detected by the microphone whether it is the ringtone to his or her mobile phone, If the user is calling the mobile phone, he can walk to the place of the storage box 2 and take out his / her mobile phone 5 to respond.

When returning to the office after the work is completed, the mobile phone 5 is taken out of the storage box 2. When this is the last remaining one, the power switch 8 is turned off. If the power switch 8 is forgotten to be turned off, it is installed near the entrance to the substation and the forget-to-turn off light connected to the interlocking contact 8a of the power switch is not turned off. This is a function corresponding to the fact that there are many unmanned substations.

In the above-described embodiment, the incoming call of the mobile phone is performed by detecting the response radio wave at the time of the incoming call. However, the incoming call can be detected by a ring tone. In this case, it is necessary to make the storage box 2 a soundproof structure in order to prevent a malfunction caused by a sound generated outside the storage box. In this case, the detection unit 7 receives the output of the microphone 6, determines that it is an incoming call when the output exceeds a certain level, and generates a contact output of the incoming call.

Although the above-described embodiment has been manufactured so as to be installed in a switchboard room of a power substation, the present invention is directed to a facility provided with a device which may malfunction due to an electromagnetic wave generated by a mobile phone. Are all applicable. For example, in order to prevent malfunction of various inspection devices used in hospitals, it is possible to use a method in which the storage box of the present invention is placed in a nurse center and an incoming call is reported by a speaker provided in an inspection room. Since the storage box in this case is installed indoors, there is no need to consider weather resistance, and the amplifier box 3 can be integrated with the storage box 2.
