Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sensor telephone having a sensor function.

[0002]

2. Description of the Related Art As prior art relating to the present invention, there are various remote monitoring devices (security systems) for the purpose of crime prevention and disaster prevention using a telephone line, and an abnormality occurs in a sensor signal connected to the security device. In this case, there is a communication modem (interface device) that automatically dials a predetermined telephone and notifies the abnormality. However, since there is only one conventional interface device, it is completely independent of the telephone, and the installation location is also different.

On the other hand, various telephones having a built-in sensor have been conventionally proposed. These are roughly classified into two types, and one is for security / remote control. For example, Japanese Unexamined Patent Publication No. 2-67068 “Button Telephone Device” is a telephone device having a built-in temperature sensor and having a function of automatically reporting a fire when the temperature exceeds a preset temperature, or Japanese Unexamined Patent Publication No. 3-15900.
No. 0 publication “In-building environment management system” and JP-A-4-9
As disclosed in Japanese Patent No. 535, "Air Conditioning Network System", a system has been invented that centrally manages information of a temperature sensor built in a telephone with a private branch exchange and is useful for disaster prevention and air conditioning control. However, these sensor-equipped phones are
It only functions as a sensor terminal, only unilaterally reporting an abnormal signal to the private branch exchange side, it does not make full use of the two-way communication function of the telephone, and no countermeasures against malfunctions associated with sensors were taken. That is, the sensor built into the phone had a single function and was not intelligent.

The other one is intended to support telephone conversation. For example, Japanese Unexamined Patent Publication No. 62-90062 “button telephone” and Japanese Unexamined Patent Publication No. 62-90064 “button telephone device” are telephones with a built-in optical sensor, which detect when the surroundings of the telephone become dark, It is for automatically illuminating a display board or the like. Further, Japanese Laid-Open Patent Publication No. 62-200896 discloses a "button telephone device" which is a telephone with a built-in human detection sensor, which detects the absence of the telephone user and automatically transfers the absence.

As described above, the common features of the prior art are that the sensor has a single function, there is no bidirectional sensor information, and no countermeasures against malfunctions associated with the sensor are taken. The processing is performed by a main unit or a private branch exchange different from the telephone with a built-in sensor, and the telephone is only a sensor terminal. Therefore, the telephone with the built-in sensor according to the conventional invention has a problem in practical use, and is not widely used.

Further, various sensors are usually arranged in each room and wired to the above interface device.
As one example, there is a home automation system, and a full-scale security system constituted by a home bus system is also realized. However, in these systems, the interface unit is the core and the telephone is only a voice terminal device. Since such a home automation system requires large-scale wiring work, introduction of the system was not economical unless the home was newly built or renovated. In addition, once the system was constructed, there was a drawback that it lacked flexibility when remodeling.

As the security sensor, a fire sensor, a gas leak sensor, an oxygen deficiency sensor, an intrusion sensor, a crime prevention sensor such as a window / door opening / closing detection, etc. are used. Many of these sensors usually operate on a 100V commercial power supply. For example, as a gas sensor for detecting combustible gas such as city gas or propane gas, there is a track record of oxide semiconductor type such as tin oxide and zinc oxide, and these sensors have a built-in heater and generally have an operating temperature of 300 to 450. It is a high temperature of ℃. Therefore, it consumes a large amount of power and cannot be driven by a battery. A battery-operated gas sensor operating at room temperature has also been developed in the past, but it has not been widely used due to its problems in stability, reliability, reproducibility, and battery life.

On the other hand, since wireless telephones such as cordless telephones, mobile telephones and car telephones are used as mobile telephones, they usually use a secondary battery as a power source. The secondary battery must be charged without fail, and charging is performed using a dedicated charger. This charger is used, for example, in the form of a charging stand on which a cordless telephone handset is mounted on the charger. When the telephone is not used for a long time such as at night, the cordless telephone handset is usually placed on a charging stand for charging. However, the conventional charging stand has only the function of charging.

The inventor of the present invention has analyzed the usage pattern of the wireless telephone, and has realized that the security and the wireless telephone are very compatible with each other. That is, from the viewpoint of crime prevention and disaster prevention, when the wireless telephone is not used for a long time, that is, when the wireless telephone is being charged, no person is present, and crime prevention and disaster prevention are required. . Of course, there are no wireless type telephones such as commercially available cordless telephones that satisfy the object of the present invention.

[0010]

As described above, in the conventional security system, the wiring between the sensor and the security interface is indispensable, and when a security abnormality is reported to the outside by using the telephone line, the interface is used. It was further wired to the phone. Therefore, a large amount of initial investment was inevitable for the security system construction.

On the other hand, in recent years, the use of cordless telephones has rapidly spread, and the environment and usage of telephones are changing. For example, wireless mobile communication such as car phones and mobile phones is expected to further develop, and the age of personal communication in which each individual has an ID number will soon emerge. A wireless phone always needs to be charged with a secondary battery.
00V commercial power supply or car battery is used.
People are absent when they are charged, and this is the time when crime prevention and disaster prevention are required.

The present invention has been made in consideration of such a new telephone environment of the future and the actual usage of a cordless telephone which is explosively popularized, and its purpose is to provide a flexible local wiring-free local area. It is to ensure security economically and easily, and in a form that suits the actual conditions of life.

[0013]

According to a first aspect of the present invention, there is provided a sensor-equipped charging stand, comprising a plurality of sensors for detecting various kinds of predetermined information, and a secondary battery of a sensor telephone body via a charge coupling mechanism. The sensor telephone main body includes a charging circuit for charging, a sensor signal processing circuit that detects an abnormality in the output from each sensor and sends an abnormality signal to the sensor telephone main body, and a signal coupling mechanism to the sensor telephone main body. A signal coupling mechanism for coupling with the signal coupling mechanism of the sensor-equipped charging stand, and an automatic dial circuit for automatically dialing a telephone number registered in advance when an abnormal signal is detected.

According to a second aspect of the present invention, the sensor comprises a plurality of security sensor groups such as a gas leak sensor for flammable gas, an oxygen deficiency sensor, a fire sensor, and a crime prevention sensor.

According to a third aspect of the present invention, the sensor telephone main body comprises an automatic response circuit from an outside line, a sensor selection circuit by a push button signal, and a sensor information voice notification circuit.

According to a fourth aspect of the present invention, the main body of the sensor telephone has a dedicated sensor button for calling the sensor information, and the sensor selection circuit operates by using both the sensor button and the push button signal. is there.

In a fifth aspect of the present invention, the sensor telephone main body is a cordless telephone, and has a handset selection switching means by a push button signal from an outside line.

According to a sixth aspect of the present invention, the sensor-equipped charging stand detects the abnormality of the output from each sensor and outputs an abnormality signal to the main body of the sensor telephone, and the output of this sensor signal processing circuit. It has a sensor system independent of the main body of the sensor telephone including a voice synthesizing circuit for converting into a voice and an alarm means for giving an abnormal signal from the sensor signal processing circuit.

[0019]

According to the sensor telephone of the present invention, charging is started when the sensor telephone main body is mounted on the sensor-equipped charging stand, and at the same time, the sensor group and the sensor telephone main body are electrically coupled by the signal coupling mechanism. Therefore, when the sensor group detects an abnormal signal, the sensor signal is transmitted to the main body of the sensor telephone, and the automatic dial circuit works to inform the outside of the security abnormality by voice. In this way, by using the wireless type sensor telephone for cordless transmission of the sensor signal obtained by voice conversion, the wiring between the individual sensor and the interface, which is required in the conventional security system, becomes unnecessary.

Next, in order to facilitate understanding of the present invention, various functions provided in the sensor telephone of the present invention will be described in advance before describing the embodiments of the present invention. First, the sensor will be described. The sensor telephone of the present invention is
As the operating voltage of the sensor, a security sensor driven by a 100V commercial power source, which has a proven track record at present, can be used. Also,
It may be driven by a car battery. This is because the wireless type telephone is equipped with a secondary battery and must be charged by a car battery in the case of a 100V commercial power source or an automobile telephone. Of course, even if the battery-driven sensor is highly reliable, there is no problem in using it.

The type of sensor is a gas leak sensor for combustible gas of LPG such as city gas or propane gas,
A plurality of security sensors such as an oxygen deficiency sensor such as a CO gas sensor, a smoke sensor, a flame sensor, a fire sensor such as a diaphragm or a bimetal, and a crime prevention sensor such as a human detection sensor. From the viewpoint of ensuring reliability, these sensors are preferably equipped with a plurality of sensors having different operation principles.

For example, in the case of a fire sensor, there are two combinations of a smoke sensor and a heat sensor made of bimetal. In the case of a crime prevention sensor, a combination of a pyroelectric type human detection sensor (called an intrusion sensor) and a semiconductor pressure sensor can be mentioned. Alternatively, combining this with an illuminance sensor further increases reliability. This pressure sensor detects a slight change in pressure in the room when a door or a window is opened or closed. Therefore, the presence of a person can be detected even in a remote place.

The illuminance sensor detects the brightness of the room, that is, whether or not the light is on at night. Note that many security sensors generally detect the opening and closing of doors and windows with a combination of a magnet and a reed switch or a hall element.In this method, signal transmission between the sensor-equipped charging stand and these detectors is not possible. It is not suitable for taking advantage of the features of the sensor telephone of the present invention because it becomes necessary. In addition, in the case of the gas leak sensor, although the power consumption is large, the above-described oxide semiconductor type combustible gas sensor has a track record and is preferable.

The CO gas sensor is effective for preventing the gas poisoning due to the incomplete combustion of the oil stove or the instantaneous water heater, but at the same time, it complements the gas leak sensor, so that it is reliable to combine the combustible gas sensor and the CO gas sensor. It is effective in improving the property. As the various sensors described above, commercially available ones can be appropriately selected and used in the sensor telephone of the present invention.

Next, the sensor-equipped charging stand has a sensor system function that is independent of the others, and includes a sensor signal abnormality determination function, an alarm function, and a sensor signal voice conversion function. These are realized by processing the sensor signals by a built-in microcomputer. The sensor signal abnormality determination function determines whether or not there is an abnormality by comparing a preset signal value and a sensor signal value.

The feature of this sensor system is, of course, that it can be distinguished for each individual sensor. However, for example, in a fire sensor, a signal abnormality is checked in a sensor group having different operation principles such as a smoke sensor and a bimetal. The determination is abnormal only when the signals of a plurality of sensors are both abnormal, and the determination pending warning is issued when only one sensor is abnormal. The sensor abnormal signal discrimination function is composed of a sensor signal processing circuit and a memory, and has realized the reliability improvement of a security sensor, which has been a problem in the past, by signal processing by a plurality of sensors and a microcomputer.

The alarm function is composed of an LED display circuit and a speaker. When an abnormal sensor signal is detected, a built-in bell or a synthetic voice notifies the surroundings of the abnormality and L
The ED is displayed. In the case of the above judgment hold, no alarm sound is emitted, but it is possible to know which sensor is abnormal by the LED display.

The voice converting function of the sensor signal is composed of a voice synthesizing circuit and is a function peculiar to the present sensor telephone, which converts the sensor signal into voice synthesized voice and transmits it to the main body of the sensor telephone. By performing voice conversion in this way, it is possible to cover the drawback that the transmission band of the telephone line is as narrow as 0 to 4 kHz, and to transmit accurate information. In addition,
Two types of transmission methods are possible. One is a method in which the speaker of the sensor-equipped charging stand converts the sound into a sound, and the sound is received by the handset of the sensor telephone body (using a so-called room monitor function), and the sensor information is transmitted to the outside line. The other one
The other is a method of converting to voice-synthesized sound and transmitting it as an audible frequency to the sensor telephone body.

By pressing the sensor call-only button (sensor button) of the sensor telephone and then designating the sensor with the PB button, the specific sensor information of the own sensor-equipped charging stand can be confirmed by voice synthesis sound. In the case of a cordless telephone type, the sensor-equipped charging stand or the built-in sensor information can be confirmed by voice synthesis between the slaves or between the slave and a master (described later).

As described above, in the sensor telephone of the present invention, if the sensor-equipped charging stand is connected to, for example, a 100V commercial power source, the sensor group operates independently, so that the sensor telephone main body is used. It is possible to independently notify the sensor signal abnormality to the surroundings by the display of the built-in alarm device or LED regardless of the presence or absence of the sensor and the presence or absence of the sensor telephone main body mounted on the sensor-equipped charging stand. Of course, if the sensor telephone main body is not mounted on the sensor-equipped charging stand, it is impossible to report sensor information to the outside or monitor sensor information from the outside by telephone.
However, in the case of a cordless telephone, by incorporating a sensor system having the same function as that of the present invention in the base unit, a security system other than a power failure can always be operated in at least one place in the home.

Next, the signal coupling function may be either a contact method or a non-contact method. In the case of the contact method, for example, when the signal is transmitted by the contact pieces provided on both the charging base with the sensor and the telephone body, it is necessary to ensure the electrical continuity when the main body of the telephone is mounted on the charging base with the sensor. Therefore, the contact piece on one side needs to be supported by the elastic body.

Further, it is desirable that these contact pieces are not exposed to the outside from the sensor-equipped charging stand and the main body of the telephone from the viewpoint of malfunction or safety when not mounted. In the case of the non-contact method, there is a method of electromagnetically coupling with a known built-in transformer. It is superior in safety, durability, and reliability compared to the contact method, but when reducing the pitch between transmission lines, it is necessary to consider crosstalk due to leakage of magnetic flux. Further, as a non-contact method, it is possible to adopt an optical coupling method in which optical-electrical (0-E) signal conversion is performed and end faces of optical fibers are opposed to each other. As described above, the sensor signal coupling mechanism can be appropriately selected from known signal transmission systems.

The charging function may be implemented by a commercially available cordless telephone, that is, a method of converting 100V into, for example, 3.6V by an independent power adapter and supplying it to the sensor telephone main body. , By incorporating the voltage converter into the sensor-equipped charging stand,
It can take a neat shape in terms of design. Power supply from the sensor-equipped charging stand to the sensor phone body
The method using contact pieces which is generally used at present is preferable.

Next, the function of the sensor telephone main body will be described. The sensor phone itself has an automatic response function to the call from the other party, a sensor selection circuit by the PB signal, a function to receive a signal from the sensor-equipped charging stand, and a function to automatically dial a pre-registered phone, and a function to notify a sensor abnormality by voice. ，
It is equipped with a room monitor function that uses a telephone handset.

The automatic answering function is for calling the sensor telephone of the present invention at home from outside and listening to the sensor information, and is usually the same as the function provided in the answering machine. After the phone is connected, the sensor can be selected by the PB signal. When the sensor phone is a cordless phone, a slave unit can be designated.
The sensor information can be heard as a synthetic voice by the voice notification function described below.

As a voice notification function, a voltage change (for example, 0 V in a normal state and 1.5 V in an abnormal state) is detected by the signal coupling mechanism when one of the sensor signals in the sensor group becomes abnormal, and the sensor telephone main body. When a voltage change is detected by the sensor telephone body, the voice message “emergency call!
Emergency call! This is XXX. An error was detected in the sensor signal, please check the sensor. "
And a voice guidance of the sensor check method is possible. Alternatively, it is also possible to perform signal processing in advance by the sensor system on the sensor-equipped charging stand side and transmit the abnormality to the sensor telephone main body when a plurality of sensors have abnormal signals at the same time.

There are two methods of transmitting the sensor information from the sensor-equipped charging stand to the sensor telephone main body. One is to receive the sensor information from the sensor-equipped charging stand as an audible signal and transmit the audible signal to the other party as it is. Is the way to do it. The second is a method in which the main body of the wireless telephone is set to the room monitor function, and the sound of the speaker built in the sensor-equipped charging stand is received by the handset. Either method may be used, but as in the above-mentioned example, the main body of the sensor phone is required to have a voice synthesis notifying function for notifying the other party of the emergency call from where the call originates.

The function of the present invention has been described above.
If the sensor telephone of the present invention is used, it is possible to select and switch a specific sensor in the built-in sensor group from a destination with a PB signal and monitor the sensor information by voice response. The sensor phone of the present invention has a plurality of built-in sensors.
There are two characteristics. Equipped with a sensor having a different operation principle, it is possible to reduce the malfunction that has been a problem in the conventional security sensor. For example, as described above, if an abnormality is detected in any one of the sensor groups,
Make settings to notify the registration destination phone by the automatic dial function. Then, by using a smoke sensor and a CO gas sensor together as a fire sensor, it is possible to adopt a method of sequentially confirming individual sensor information by a PB signal switching function to determine whether or not a malfunction has occurred.

As another example, by adding a room monitor function by a handset to the sensor telephone of the present invention, it is possible to check from the monitor sound whether or not the human detection sensor (security sensor) of the sensor-equipped charging stand is malfunctioning. Is also possible. Further, when there are a plurality of cordless handsets in the cordless telephone, it is possible to designate a particular cordless handset by a PB signal from a destination. Therefore, designation of cordless handsets can be changed sequentially to perform a human detection sensor and a room monitor. For example, it is possible to determine whether it is due to a malfunction of the sensor or whether a thief has actually entered. Further, if it is known that a thief has entered, it is possible to sound an alarm by a PB signal from a destination. The sensor telephone of the present invention can be used in various ways other than the above example.

[0040]

EXAMPLE An example of the present invention will be described below. (Embodiment 1) FIG. 1 is an external perspective view of a sensor-equipped charging stand,
FIG. 2 is a schematic diagram of a circuit block diagram of the present invention configured by adding the sensor system of the present invention to a low power cordless answering machine. The sensor-equipped charging stand 100 is connected to a 100V commercial power source, operates independently of the wireless sensor phone main body 200, and has the function of displaying the sensor state as described above.
The built-in speaker is equipped with a function for reporting abnormalities by voice synthesis, a function for coupling sensor signals to the sensor phone body, and a charging mechanism.

As shown in FIG. 2, the sensor-equipped charging stand 100 is equipped with a gas sensor 1, a fire sensor 2 and a crime prevention sensor 3, and as shown in FIG.
It can be known by 2A and 3A. Each indicator light 1A,
2A and 3A are divided into three types of green, orange and red respectively. Green is a normal state, orange blinking is one of a plurality of sensors in an abnormal state, and red blinking is when all the sensors are in an abnormal state. The security sensor 3 is provided with a security sensor switch 15 so that the security function can be stopped while at home.

When the sensor telephone main body 200 is mounted on the sensor-equipped charging stand 100, charging is started via the charging contact pieces 21A provided on both sides, and at the same time, the signal coupling contact pieces 22A, 23A provided on both sides are connected. A sensor signal and a sensor selection signal can be transmitted via this. Note that FIG.
In (b), the charging contact piece 2 on the sensor telephone main body 200 side
1A and the signal coupling contact pieces 22A and 23A are omitted. Charging contact piece 21A and signal coupling contact piece 22
For safety reasons, A and 23A are housed inside each by a spring mechanism so that the sensor phone main body 200 is not mounted on the sensor-equipped charging stand 100 so that it cannot be easily touched by the outside. ing. FIG. 1B shows a state where the sensor phone main body 200 is placed on the sensor-equipped charging base 100 and is being charged. In addition to the PB 41, the outside line button 42, and the inside line button 43, the sensor phone main body 200
A sensor button 44 is attached, so that the sensor state of the sensor-equipped charging stand 100 of the own device or the child device can be checked.

In the circuit block diagram of FIG. 2, the upper side surrounded by the chain double-dashed line shows the sensor-equipped charging stand 100, and the lower side shows the main circuit blocks of the sensor telephone main body 200.
First, the sensor-equipped charging stand 100 will be described.

In this embodiment, as the gas sensor 1, an oxide semiconductor type combustible gas sensor 1a made of tin oxide,
Oxide semiconductor type CO gas sensor 1 made of zinc oxide
b, scattered light type smoke sensor 2a as fire sensor 2, bimetal type heat sensor 2b, ceramic pyroelectric type human detection sensor 3a made of lead zirconate titanate as security sensor 3, semiconductor pressure sensor type human detection sensor 3b is connected via the switch 4 and is in use. Although the output of the gas sensor 1 is an analog amount, the other fire sensor 2 and the crime prevention sensor 3 output an ON-OFF signal.

Although not shown in the figure, the output of each gas sensor is previously amplified within the range of 0 to 5 V by an amplifier (not shown). There are two systems of outputs from these sensor groups, one system enters the multiplexer 5, and after sensor selection switching, enters the sensor signal processing circuit 6. The other system directly enters the sensor signal processing circuit 6 without passing through the multiplexer 5. The multiplexer 5 is an analog switch for switching sensor signals, and sensor selection switching is controlled by sensor selection from the sensor telephone main body 200.

On the other hand, the sensor signal group directly entered into the sensor signal processing circuit 6 is processed in the sensor signal processing circuit 6 while referring to the memory 7, and any one of the gas sensor 1, the fire sensor 2 and the crime prevention sensor 3 is processed. When the two sensors, for example, the smoke sensor 2a and the heat sensor 2b in the case of the fire sensor 2 simultaneously show an abnormality, an automatic dial command signal is issued to the sensor telephone main body 200 side. At the same time, a signal is sent to the LED display circuit 9 which is one of the alarm means, and the indicator light 2A made of the LED of the fire sensor 2
Flashes red. Furthermore, a signal is also sent to the voice synthesizing circuit 10, and a built-in speaker 11, which is one of the alarm means, gives an alarm to the surroundings, "A fire has occurred."

On the other hand, when an abnormality is detected in any one of the above-mentioned sensors, it is sent to the LED display circuit 9, the corresponding sensor LED is displayed blinking in orange, and the speaker 11 "Please check the sensor. Please check the room. " At the same time, the sensor phone body 2
An automatic dial command signal is issued to the 00 side, and a voice message requesting a sensor check is sent to the partner telephone. The other party's telephone can operate the PB button to confirm the sensor information or monitor the room by the receiver to check whether the sensor is malfunctioning or not, which can be useful for preventing disasters.

For example, in the case of an initial fire, it is considered that only the smoke sensor 2a of the fire sensors 2 will first detect an abnormality and will notify the automatic dial. In this case, by checking the gas sensor 1 as well, the increase in the CO gas concentration can be confirmed by voice response. Since the sensor signal of the gas sensor 1 is an analog quantity, the voice response says, "The combustible gas concentration has increased a little."
"The CO gas concentration is approaching a dangerous level."
It is converted into an easy-to-understand message by fuzzy processing and made to respond. These speech synthesis is performed by the sensor signal processing circuit 6 and the speech synthesis circuit 1 on the sensor-equipped charging stand 100 side.
It is 0. The sensor-phone main body side 200 transmits the voice synthesis signal converted into the audible signal from the antenna 39 to the partner telephone.

As described above, the sensor signal processing circuit section 6
Is responsible for the central function of the sensor system of the sensor telephone, and fulfills the functions of abnormal signal discrimination, automatic dial command, voice conversion signal transmission, and alarm. Note that once an abnormality is detected, the alarm is continued unless the reset circuit 8 resets the sensor system. The reset operation turns off the power supply circuit 12 of the sensor-equipped charging stand 100.
Or put the handset of the telephone to be dialed automatically and terminate the communication.

The sensor-equipped charging stand 100 of the present invention has a charging function similar to that of a conventional cordless telephone. However, since the charging circuit 13 for converting the voltage of 100V is built in, the conventionally used charging adapter is unnecessary. As described above, the charging from the sensor-equipped charging base 100 to the sensor telephone main body and the signal transmission between the sensor-equipped charging base 100 and the sensor telephone main body 200 include the charging contact piece 21A and the signal coupling contact pieces 22A and 23A. The charge coupling mechanism 11 and the signal coupling mechanism 12 are used. Reference numeral 14 is a plug, A is a sensor abnormal signal discrimination function, B is an alarm function, and C is a portion surrounded by a dotted line.

Next, the sensor telephone main body 200 will be described. As described above, when the sensor-equipped charging stand 100 detects a sensor abnormality, an automatic dial command signal is issued to the sensor telephone main body 200 side via the signal coupling mechanism 21. In response to this signal, the sensor telephone main body 200 automatically dials a telephone registered in advance by the automatic dial circuit 32, and the voice alert circuit 33 on the sensor telephone main body 200 side displays, for example, "emergency call! Emergency call! It is XX.An abnormality was detected in the sensor signal.
Please check the sensor. Or, "Emergency call! Emergency call! This is XXXXX. A fire has occurred. A fire has occurred."

In the sensor telephone main body 200, when the automatic response circuit 34 is activated by a telephone call from an outside line and the sensor-equipped charging base 100 is charging, the sensor selection circuit 35 mainly including the PB signal analysis circuit selects the sensor. The signal is transmitted to the multiplexer 5 on the sensor-equipped charging stand 100 side via the signal coupling mechanism 23. In this block diagram, the original function of the cordless telephone is abbreviated as the call control circuit 31. The above-mentioned automatic dial circuit 32, voice notification circuit 33, and automatic response circuit 3 which are circuits unique to the sensor telephone.
4, the sensor selection circuit 35 and the slave selection switching circuit 36 are incorporated in the call control circuit 31.

By using the automatic response function, it is possible to call the home away from home and check the state of the home with the sensor. That is, the sensor phone main body 200 has a function of checking the sensor information of the slave unit from the outside line. In this case, the personal identification number is sandwiched by # after the telephone number, the slave unit number is separated by *, and # is added to the end of the sensor number. For example, when calling 03-3567-7890, the personal identification number is 1234, and the third sensor of the first slave unit is designated, 033567789 # 1
234 # 1 * 3 #. In this way, the information of the designated sensor of the designated child device can be known by the voice response. When it is desired to sequentially know all the sensor information of all the slave units, the designation of the slave units and the designation of the sensor numbers are simplified and # 9 # is input after the personal identification number. In the previous example, 033567
7890 # 1234 # 9 #.

Next, the sensor telephone main body 200 has a function of checking the sensor information of the slave unit between the extensions. In this case, after pressing the extension call button and the cordless handset number, the sensor button is pushed to input the sensor number. That is, (extension button) (slave unit number) (sensor button) (sensor number). When checking the sensor information of the own device, the sensor button is pressed and the sensor number is input.
That is, it becomes (sensor button) (sensor number).

If the sensor telephone of the present invention is also used as the telephone for the outside line, that is, if the sensor telephones are connected to each other, by using the sensor button as in the case of the extension line, the delimiter mark designated by the cordless handset is used. (*) And the sensor number end mark (#) can be omitted, which makes the operation easier to understand. For example, in the previous example, 033567789
0 # 1234 # (slave unit number) (sensor button) (sensor number). (Embodiment 2) FIG. 3 is a schematic diagram of a circuit block for explaining a second embodiment of the sensor telephone of the present invention.
Sensor-equipped charging stand 100 and sensor telephone main body 20
The function of 0 is simplified. In the circuit block diagram of FIG. 3, the upper side surrounding the chain double-dashed line shows the sensor-equipped charging stand 100, and the lower side shows the main circuit blocks of the sensor telephone main body 200. The same reference numerals as those in FIG. 2 indicate the same parts, and 45 indicates a room monitor circuit. In this second embodiment, the sensor system of the present invention is added to a low power cordless answering machine.

First, the difference from the first embodiment will be described. As the functions of the sensor telephone main body 200, the automatic response circuit 34 from the outside line and the sensor selection circuit 35 described in the first embodiment are omitted. Accordingly, the sensor-equipped charging stand 100
On the side, the multiplexer 5 is omitted, and the sensor signal processing circuit 6 is also simplified, so that the sensor audible signal from the sensor signal processing circuit 6 to the sensor telephone main body 200 side is not directly transmitted.

Therefore, for example, it is not possible to call home from the outside to know specific sensor information by voice response. Also, there is no sensor check function between extension slaves. However, when a sensor abnormality occurs, the automatic dial circuit 32 has a function of making a voice notification to the telephone of the registration destination. Therefore, when the notification is received, the room monitor function by the room monitor circuit 45 provides the inside of the house. Can be perceived. The above is the difference from the first embodiment.

Next, the sensor-equipped charging stand 100 will be described.
The sensor-equipped charging base 100 incorporates a ceramic type pyroelectric type human detection sensor 3a made of lead zirconate titanate and a semiconductor pressure sensor type human detection sensor 3b, which are the same as those in the first embodiment, as the crime prevention sensor 3, and an ON-OFF signal is supplied. Is output to the sensor signal processing circuit 6. The sensor signal processing circuit 6 determines whether or not the two sensors 3a and 3b are abnormal at the same time, and if they are abnormal, the signal coupling mechanism 22 by a transformer provided in both the sensor-equipped charging stand 100 and the sensor telephone main body 200 is used. An automatic dial signal is transmitted to the sensor phone main body 200 side. At the same time, the voice synthesizing circuit 10 and the speaker 11 generate a warning sound "A thief is a thief" to warn an intruder. In addition, while at home in the crime prevention sensor,
A switch 4 is provided so that the crime prevention function can be stopped.

Next, the sensor telephone main body 200 will be described. As described above, when the sensor-equipped charging stand 100 detects a sensor abnormality, the automatic dial command signal is transmitted to the sensor telephone main body 200 side via the sensor signal coupling mechanism 22. Upon receiving this signal, the sensor telephone main body 200
Automatically dials a telephone that has been registered in advance by the automatic dial circuit 32, and the message "Emergency call! Emergency call! This is XXXXX" is displayed by the voice notification circuit 33 on the sensor telephone body 200 side. Be reported. After the message is reported, the room monitor circuit 44 is switched to, and the room monitor function of the microphone 37 of the sensor telephone main body 200 allows the user to know the content of the emergency call such as "Thief. Thief."

In this embodiment, the security sensor 3 is used as the sensor.
However, since the content of the notification changes on the sensor-equipped charging stand 100 side and the message on the sensor telephone main body 100 side does not depend on the sensor, the sensor telephone main body 200 has various common configurations. A sensor-equipped charging stand 100 equipped with a sensor can be used. Therefore, a highly versatile sensor telephone can be realized. For example, by placing a sensor-equipped charging stand 100 with a built-in combustible gas sensor in the kitchen, it is possible to early detect and report a gas leak from the gas stove.

On the other hand, in the living room where the oil stove is placed, C
By placing the sensor-equipped charging stand 100 having the O gas sensor built-in, it is possible to prevent a monoxide poisoning accident. The automatic dialing destination is not limited to the outside line, but if you set it to ring all the extension lines, you can report the abnormality to all the people in the house as a slave unit, and the content of the abnormality is detected by the speaker sound of the sensor-equipped charging stand. You can find out by using the room monitor function of the phone itself. Note that once an abnormality is detected, the reset circuit continues to give an alarm unless the sensor system is reset. The reset operation is completed by turning off the power supply of the sensor-equipped charging stand or by placing the handset of the telephone to which the automatic dialing is made and disconnecting the communication. As described above, the present embodiment has a characteristic that the function is simple but versatile.

In each of the above-mentioned embodiments, the sensor telephone based on the cordless telephone has been described, but the same effect can be obtained in the mobile telephone and the automobile telephone.
Further, the sensor system of the present invention can of course be incorporated not only in these wireless telephones but also in, for example, a base unit of a cordless telephone or a conventional telephone. The sensor telephone according to the present invention enables the conventional home security by incorporating the sensor system function in the sensor-equipped charging stand.

For example, in the case of an automobile telephone, if a vibration sensor or an acceleration sensor is used as a sensor, it is possible to give an early report of the theft of the automobile. This is because if the vehicle phone type sensor telephone of the present invention is set so as to automatically notify a pager when leaving the car, the car telephone type sensor telephone of the present invention detects vibration and acceleration when the thief leaves the car, and This is because we will make an emergency call. In this way, by using the wireless telephone for the transmission of the sensor signal, the wiring required in the conventional sensor becomes unnecessary.

The transmission band of the telephone is the audible frequency range of 0 to 4 kHz, and the frequency band is not wide. However, in the case of the sensor telephone of the present invention, the signal band is used for temporarily converting the sensor signal into voice and transmitting it. Does not matter. Further, when ISDN telephones (digital telephones) become widespread in the future, two B channels of 64 kbit / sec will be provided.
A 16 kbit / sec D channel can use one digital line. If the sensor signal can be directly transmitted through the digital telephone line, the restriction on the frequency band will be relaxed.
