Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As a conventional technique of this type of telephone, a communication modem capable of remotely controlling various devices such as a cooler and a bath from the telephone is commercially available. In addition, various remote monitoring and control devices using telephone lines have also been put into practical use, and when an abnormality occurs in the sensor signal connected to the remote monitoring device, a predetermined telephone or pager is automatically dialed,
There is also a communication modem that reports an abnormality. In addition, an answering machine with a room monitor function that allows the user to know the inside of the house (the appearance of a baby, forgetting to turn off the television, etc.) from the outside through a telephone receiver has been put into practical use.

However, a conventional telephone of this type does not have a built-in sensor, the telephone and the sensor terminal are completely independent, and the installation location is different. In addition, the two-way communication function, which is a characteristic of telephones, is not fully utilized.
When it was turned off or when it was a security sensor, it only received an error report such as a fire or gas leak.

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 with a built-in temperature sensor, which has 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 “Environmental management system in building” and JP-A-4-9
As disclosed in Japanese Patent No. 535, "Air Conditioning Network System", there is invented a system 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 measures against malfunctions associated with sensors have not been 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 calls. 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 performs the absence transfer.

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 measures against malfunctions associated with the sensor are not 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.

Particularly in the case of a sensor, malfunction always occurs, and improvement of reliability is always a problem. The sensor is built into the telephone and the two-way communication function of the telephone is fully utilized.For example, knowing the sensor information of the communication destination and remotely controlling various functions based on that information, or installing multiple sensors with different detection principles. However, the telecontrol system and the security system that can check the malfunction of the sensor from the outside when the abnormality notification is received have not been put into practical use.

Further, as home automation in the home, a full-scale security system constituted by a home bus system has been realized, but in these systems, the interface unit is the center and the telephone is only one terminal device. Further, since the home automation system requires a large-scale construction, it was difficult to introduce the system unless the house was newly built or remodeled.

[0009]

Recently, the use of cordless telephones has spread rapidly, and the environment and usage of telephones are changing. For example, it is considered that mobile communication such as car phones and mobile phones will further develop, and an era of personal communication in which each individual has an ID number will soon emerge. In consideration of such a new telephone environment of the future, by incorporating a sensor function in the mobile phone, the sensor phone of the present invention enables personal and local security assurance that has not been heretofore considered.

Further, since the conventional telephone uses only voice as a communication means, it lacks a sense of realism. Videophones, which are expected to become popular in the future, are a powerful means of immersive communication, but the environmental information of the other party cannot be sufficiently conveyed only by video. We believe that if various sensor information (environment, atmosphere) of the other party can be transmitted to the other party by voice or liquid crystal display, and if the atmosphere of the other party can be reproduced at hand, more realistic communication can be realized. Be done.
However, there is no telephone having such a function.

The present invention has been made in view of the above circumstances, and its purpose is to provide not only a reliable home security but also a personal computer by incorporating an intelligent sensor function in a wireless telephone itself. It is to contribute to the realization of security and presence communication.

[0012]

[0018]

According to the sensor telephone of the present invention, the sensor and the sensor interface are built in the telephone, and the type of the built-in sensor can be selected at a specific frequency from the outside or by the push button operation of the own device. It is possible to report the sensor signal to the call partner or the person or both the call partner and the person at the same time regardless of whether or not the user is on the phone.

Conventional telephones are dedicated to voice and are dedicated terminals for human-to-person communication (human interface). However, the sensor telephone of the present invention naturally and human beings in addition to the conventional voice terminal function. It has a new terminal function for communication with (Nature Interface). Therefore, it is possible to use various new telephones that were impossible in the past.

Further, the security function is autonomously performed by the polling method, and the built-in sensor is monitored.
When an abnormal signal is detected, it is notified to a remote place by an alarm sound or an automatic dial function. Therefore, since the telephone is also a security sensor terminal, local security and private security can be easily secured by modifying a cordless telephone, a mobile telephone, or a car telephone to the sensor telephone of the present invention.

[0021]

[Embodiment 1] FIG. 1 is a schematic diagram of a circuit block of a sensor telephone of the present invention, which is manufactured by adding a sensing system to a low-power cordless answering machine.
FIG. 2 is a detailed view of the built-in sensor group in FIG.

In FIG. 1, 100 is a sensor telephone according to the present invention, which comprises a sensor function unit 200 and a function unit 300 of a cordless answering machine (wireless type telephone). The function unit 300 of the cordless answering machine has a function as a conventional cordless answering machine, for example, a circuit portion such as an automatic answering circuit is omitted, and is represented by a call control circuit 90 as a representative. A built-in sensor group 9 including sensor units 1 to 8, a sensor switching circuit 10, a sensor signal processing circuit 20, a voice conversion circuit 30, a sensor output control circuit 40, and a push button (PB) signal for both the parent device and the child device. A main circuit, which is specific to the present invention and includes an analysis circuit 50, is mounted. Reference numeral 60 is a PB, 70 is a liquid crystal display circuit, and 80 is a power supply circuit. Although not shown in this circuit block diagram for the master unit, it is possible to access sensor information of multiple slave units from an external line.
The handset switching function is also installed. Also, 21
Is a memory, 22 is a comparator, 23 is a speaker, 31
Is a memory, 91 is a microphone, 92 is a speaker, and 93 is an antenna. It is to be noted that those having "d" in the reference numerals indicate data signals, and those having "c" indicating control signals.

Next, the built-in sensor group 9 will be described.
In FIG. 2, the built-in sensor group 9 is small and has a low power consumption type temperature sensor 1, humidity sensor 2, atmospheric pressure sensor 3, C
It is composed of an O gas sensor 4 and an odor sensor 5. As described above, there are five types of sensor elements (hard sensors), but in this embodiment, three types of soft sensors (comfort sensor 6, comfort sensor 6, obtained by signal processing of a plurality of or one sensor).
A weather forecast sensor 7 and an initial fire sensor 8) are also incorporated.

That is, the comfort sensor 6 obtains the temperature sensor signal 1d and the humidity sensor signal 2d by the signal preprocessing circuits 9a-9c of the memory 21 in accordance with the data conversion rule. The weather measurement sensor 7 was obtained by signal processing according to the comparison rule of the atmospheric pressure data of 4 points for 12 hours stored in the memory 21 every 3 hours. That is, it is based on the fact that the data of the atmospheric pressure sensor 3 decreases with time when the weather collapses.

Further, the initial fire sensor 8 has a particularly high sensitivity to the CO gas sensor 4 which detects the CO gas which increases at the time of incomplete combustion in the early stage of the fire, and has a particularly high sensitivity to the burning odor in the early stage of the fire, and to smoke or alcohol of cigarettes For both the odor sensor 5 and the memory 2
It is set to emit a signal when the thresholds of the signals stored in 1 are simultaneously exceeded. In the conventional fire sensor, for example, a single sensor such as a smoke sensor is mainly used, and malfunction occurs. However, the initial fire sensor 8 of the present invention performs signal processing on the outputs of the CO gas sensor 4 and the odor sensor 5. Has made it possible to obtain highly reliable security information.

Next, the function of the sensor signal processing circuit 20, which is one of the main components of the sensor telephone of the present invention, will be described. The built-in sensor group 9 described above is controlled via the sensor switching circuit 10 by the control signal 20c from the sensor signal processing circuit 20. The sensor signal processing circuit 20 takes in the sensor designation signal 50d from the PB signal analysis circuit 50, operates the sensor switching circuit 10 while referring to the sensor registration information in the memory 21, and performs the 1 designated by the sensor designation signal 50d.
In addition to the sensor signal 10d of one sensor, the sensor data 2
Send 0d1 information. Further, the sensor data 20d2 is sent to the liquid crystal display circuit 70.

Further, when the sensor signal processing circuit 20 does not receive the sensor designation signal 50d, the sensor switching circuit 10 is sequentially operated in a polling manner to sequentially operate the temperature sensor 1, the CO gas sensor 4, the odor sensor 5, and the initial fire. Each sensor signal value of the sensor 8 is compared with the threshold value data of the memory 21 by the comparator 22, and if a security abnormality is found, an alarm sound is emitted from the speaker 23. The autonomous driving of the sensor switching circuit 10 by the polling method is interrupted when the sensor designation signal 50d is input, and restarted when the voice synthesis response ends.

Next, the function of the PB signal analysis circuit 50, which is one of the other main components of the sensor telephone of the present invention, will be described. The PB signal analysis circuit 50 has a function of receiving the PB signal 60d from the PB 60 of the own device or the extension telephone or the PB signal 100d from the other party, analyzing the PB signal 100d, and transmitting the sensor designation information and the control information. ..
In the case of the sensor designation information, the end of the PB signal 100d always ends with "#". The sensor designation signal 50d is sent to the sensor signal processing circuit 20, and among the control information, the liquid crystal display control signal 50c1 is sent to the liquid crystal display circuit 70 and the output control signal 50c2 is sent to the sensor output control circuit 40. The sensor designation information and the control information are determined by the function key (*: handset number, #: sensor number) added before the PB number.

For example, in the case of designating the second sensor of the first handset from the other party's telephone (for example, when calling from home to the other party), next to (phone number)-(# password #) , (* 1 # 2 #) on the PB60. When the PB signal analysis circuit 50 detects * 1, the PB signal analysis circuit 50 outputs the output control signal 50c2 for stopping the output of the sensor other than the first slave unit, and also detects (# PIN #) first to call from the outside. Liquid crystal display control signal 50c
Give 1. This is because, as will be described later, in the case of a future digital telephone, data can be transmitted by the D channel (or another B channel), but in the case of the present analog telephone, a liquid crystal display signal is transmitted to the other telephone. Because you cannot do it.

[Telephone number]-(# PIN #)-
The (# device operation number #) input method is a remote operation method that is currently generally used in an answering machine, and a personal identification number is used to prevent unauthorized access to another person. In addition, from the base unit or own unit (* 1 # 2 #)
When PB is directly input, the information of the second sensor of the first child device is displayed on both the parent device and the own device on the liquid crystal display, and at the same time, the sensor information is confirmed or malfunction is checked by voice response. be able to.

Next, the function of the voice conversion circuit 30, which is one of the other main components of the sensor telephone of the present invention, will be described. The voice conversion circuit 30 sends a voice synthesis sound to the sensor output control circuit 40 while referring to the memory 31 based on the sensor data 20d1 from the sensor signal processing circuit 20.
In the memory 31, a large number of sensor data output patterns such as “current temperature is XX degrees.” Are registered.

Next, the function of the sensor output control circuit 40, which is one of the other main components of the sensor telephone of the present invention, will be described. As described above, the sensor output control circuit 40 outputs the output control signal 50c2 from the PB signal analysis circuit 50.
It is controlled to stop the output of the sensor other than the designated slave unit, and has a function of interrupting the voice data 30d created by the voice conversion circuit 30 to the next call control circuit 90. That is, the sensor output control circuit 40
Call interrupt control signal 4 sent from the call control circuit 90 from the call
0c adjusts the volume level of the microphone 91, and the audio data 40d transmitted from the sensor output control circuit 40.
Is interrupted to the person or the other party or both the person and the other party. Therefore, the sensor information of each other can be heard by the voice synthesis sound even during the call with the other party. In the case of the conventional answering machine, there was no function to interrupt the call in the answering machine mode.

Further, in the home telephone with security function, when the security sensors are accessed, the telephone is disconnected and it is not possible to talk with the other party because it is switched to the communication modem mode. In addition, the master unit is designed to always operate the sensing system, but the slave unit can operate the sensing system function only when necessary such as going out or going to bed considering the battery consumption. A sensor circuit power switch 81 is attached to the power circuit 80.

Next, a flow chart of the main operation of the sensor telephone of the present invention is shown in FIG. Note that (1) to
(18) shows each step. First, it is checked whether the telephone is in use (1), and if not in use, the security sensor polling loop is entered (2).
(4). Then, when an abnormality is detected in the sensor signal value (5), the related sensor is also examined (6), and the alarm sound is emitted only when a plurality of sensors (for example, the CO gas sensor 4 and the odor sensor 5) simultaneously show the abnormality signal. Issued (7)
(8). On the other hand, when the telephone is in use in step (1), the presence or absence of the PB signal is constantly monitored, and when the PB signal from the own device or the call partner is received (9), the sensor designation is as described above. As always, be sure to add "at the end of the PB signal"
Since there is a # ", it is determined whether the PB signal is for a call or a sensor designation (10), (11). In the case of a sensor designation, the sensor information memory 21 is referred to and the designated sensor and associated sensor are referred to. Obtain information from both (12)-
(16) After voice conversion (17), the call is interrupted and responded (18). With the above-mentioned configuration, various uses described below have become possible. (A) Home Security In the case of conventional home security, as shown in FIG.
The security sensor S1, which is a security sensor, gas leak sensor S2, fire sensor S3, etc., are not built in the telephone, but an interface unit called home terrain main unit HT etc. and each sensor were connected by wiring. And the telephone TL was only one terminal. In FIG. 5, SD is a security device, DP is an intercom, H is a home, and EX is a telephone exchange. In the case of the sensor telephone of the present invention, such wiring work is not necessary, each telephone interface is built in, and the security of the room in which the child device is placed (initial fire and gas poisoning information in the case of the present invention) is secured. It Since the cordless sensor telephone of the present invention is of a low power type and is provided with a confidential communication function by scrambling, it is less likely to malfunction due to external radio waves.

In addition, since communication between the base unit and the handset is possible in any place in a general household, the handset may be moved to a place where security is considered necessary at night or when going out. Even when the telephone is not used, if an abnormal signal is detected by the sensors, an alarm sound can be emitted from the slave unit and the master unit in which the abnormal signal is detected to notify the abnormality.

Further, as a function peculiar to the sensor telephone of the present invention, when the mode is switched to the answering machine mode, the sensor information installed in a plurality of slave units and the master unit are individually called from the outside, and the answering machine is operated. You can check the sensor information by telephone. In that case, first, after calling the base unit with the normal telephone number, according to the message of the base unit, the handset number (for example, the first handset: * 1, the base unit: *
0), sensor number (eg # 1 for the first sensor)
#) Is designated by PB60. If you want to know the information of all the sensors of all the slaves in sequence, use PB as the sensor number.
(# 9 #) 60 should be pressed. If these are specified, the sensor information can be known by the voice synthesis response.

In this embodiment, the remote control function of the equipment is not provided, but if necessary, the base unit of the sensor telephone can be equipped with a remote control interface. The connection between the base unit and the remote target device may be wired,
FM wireless or infrared transmission (so-called remote control system for TV etc.) can exhibit the characteristics of this cordless sensor telephone. (B) Local Security Use of the cordless sensor telephone of the present invention has an advantage that not only home security but also local security at a place away from home can be easily secured.
In this case, the built-in sensor is not limited to this embodiment, and an intrusion sensor or the like may be used. For example, as an example of local security, if an intrusion sensor and an illuminance sensor are built in a child machine and installed in a house, a farmer can monitor the prevention of theft of muskmelon from home at night. In the above embodiment, the automatic dialing function is not provided, but if necessary, it is also possible to automatically dial the telephone registered in advance when an abnormality is detected. (C) New application In the present embodiment, the sensor information is adapted to obtain the response without any discomfort by the fuzzy process in addition to the raw information of the sensor. For example, from the output signals of the temperature sensor 1 and the humidity sensor 2, You can get information about comfort such as "a little sultry". A feature of the present invention is that the PB (eg, # 2 #) 60 is pressed during a call (between external lines or internal lines) to select the partner's No. 2 sensor, and both parties hear the sensor information as an interrupt response by voice. be able to.
Alternatively, by simply pressing PB (2 #) 60, the information of the No. 2 sensor of the own machine can be transmitted to both sides by interruption. By using this function, it is possible to know the telephone environment such as the comfort of both rooms, the weather, etc., so that the communication between friends can be further accelerated.

Further, in the present embodiment, in the case where the sensor information is transmitted to both of the cases where the own device or the other device is designated, the result has been explained at the same time, but the sensor information may be transmitted to only one of them. It can be switched with the switch on the phone. If you do not want to tell the other party your sensor information, you can use this switch to stop the voice response function. In this case, since the sensor information of the own device can be confirmed, it is possible to check the malfunction of the sensor. [Embodiment 2] FIG. 4 is a schematic view of an entire circuit block of a car telephone type sensor telephone. In FIG. 4, reference numeral 400 denotes a functional unit of the automobile telephone, and 200 denotes a sensor functional unit, which has substantially the same configuration as that of FIG. 1 except that the liquid crystal display circuit 70 of FIG. 1 is not provided. In this example, a sensor system of the present invention was manufactured by adding a sensing system to a conventional automobile phone. The circuit portion having a function as a conventional car telephone and the automatic dialing function when an abnormal signal is detected are shown by the call control circuit 90 as a representative. Built-in sensor group 9, sensor switching circuit 10, sensor signal processing circuit 20, voice conversion circuit 30, sensor output control circuit 40,
A main circuit which is specific to the present invention and includes a push button signal (PB) signal analysis circuit 50 is mounted. This circuit block is almost the same as that in FIG. 1, and only the differences will be described below.

The built-in sensor group 9 is an ultra-small, low power consumption type vibration sensor 1 using semiconductor integrated circuit processing technology.
a, acceleration sensor 2a, direction sensor 3a, temperature sensor 4
a, a humidity sensor 5a is mounted. Also, the environmental sound from the handset can be monitored. By performing signal processing on the outputs of the temperature sensor 4a and the humidity sensor 5a, the comfort sensor 6 described in FIG. 2 can be obtained.

Further, the vibration sensor 1a and the acceleration sensor 2
a, the traveling state of the automobile can be known by the direction sensor 3a, and the speed sensor can be obtained by performing signal processing on the acceleration sensor 2a. While traveling, you can listen to sensor information hands-free using a headphone / microphone set for safety.

The sensor signal processing circuit 20 sends a control signal from the comparator 22 to the sensor output control circuit 40 when each sensor under polling exceeds a preset sensor signal value, and the registered telephone set. You can automatically dial the number and make an emergency call for any abnormality. Further, in order to make an emergency call to the pager with a display function by a liquid crystal display, an output circuit of the sensor signal processing circuit 20 does not pass through the voice conversion circuit 30, but a circuit which is directly sent to the sensor output control circuit 40 is added. ing. With the above-described structure, the sensor telephone of the present invention can be used as described below, which has been impossible in the past. (A) Local security (prevention of theft of automobiles, ensuring safety of passengers) For example, it is assumed that the user leaves the car for shopping while leaving the baby in the car. At that time, as a precaution, enter your pager number into the car telephone type sensor telephone, the temperature sensor 4a is 27 degrees, and the acceleration sensor 2a is 1
G, direction sensor 3a is preset to the current value of 15 degrees (North is 0 degree, angle is displayed clockwise, 15 degrees is East.), And if any of these sensors exceeds the set value,
Set the auto-dial function to auto-dial the pager.

During shopping, a pager was turned on, and the liquid crystal display message indicated that only the acceleration sensor 2a was abnormal. If the car is stolen, the direction sensor 3a and the vibration sensor 1a should also notify the abnormality, so it seems that the acceleration sensor 2a is malfunctioning. After connecting to the phone-type sensor telephone, we input the password and instructed that the monitor information of the built-in sensors be sequentially answered by voice with a push button. As a result, the vibration sensor 1a is "at rest", the acceleration sensor 2a is "the current acceleration is 2G", the direction sensor 3a is "the current direction is 15 degrees, facing the true east", and the temperature sensor 4a. "The current temperature is 26 degrees. It's a little hot and uncomfortable." Humidity Sena 5a said, "The current humidity is 64%. It's a little muggy." After that, when I selected the ambient sound monitor function with the push button and listened to the sound inside the car, I heard a difficult baby's voice, so I hung up and rushed back to the car.

The above is the description of the functions that have been made possible by the car telephone type sensor telephone of the present invention. As described above, according to the sensor telephone of the present invention, it is possible to prevent an unfortunate accident such as leaving a baby in a car under hot weather and dying due to dehydration, and to prevent malfunction of sensors. Can be remotely checked by a sensor having a different detection principle, so that the reliability of the sensor can be improved. (B) Example of realistic communication In the car phone type sensor telephone having the above-mentioned configuration, the built-in sensor information can be exchanged with each other during a normal call. Each sensor is assigned to each push button number, and the sensor assignment can be changed. Now, 1a: vibration sensor, 2a: acceleration sensor, 3a: direction sensor, 4a: temperature sensor, 5a: Assume that it is a humidity sensor. For example, when a push button (# 2 #) is pressed as a "sensor selection key" during a call between car-phone type sensor phones, the acceleration sensor 2a of the partner's sensor phone is selected, and the call is interrupted. It is 1.5G. "
Alternatively, if the push button (3 #) is simply pressed without the function key (#) at the head, the direction sensor 3a of the own machine is selected, and the voice interrupt response "the current direction is north" is made.

In this way, it is possible to know the environment conditions of the other party of the call and the own machine, and thus enjoy a live call with each other. Of course, since the sensor is built into the phone, the information of each sensor of acceleration, vibration, and direction will change when the sensor phone is swung, so put the sensor phone in a fixed position in the car for safety while driving. It is preferable to use the built-in speaker and microphone for hands-free communication. If you do not want to tell your partner about your sensor information, you can press the function button at hand to instruct to stop sensor output.

The above is an example of the inter-site communication that is possible with the current analog telephone line. 64 kbit / sec in case of integrated digital communication network (ISDN network) which will spread in the future
2 channels (B channel), 16 kbit / se
c has one channel (D channel), and the latter channel is dedicated to data transmission. Therefore, the function of making and receiving calls is greatly enhanced, and it is possible to know the type of the partner terminal, the telephone number of the calling side, etc., which were difficult with the analog telephone line.

In the case of the sensor telephone of the present invention, if the D channel is used as a sensor output, the sensor information can be continuously output without disturbing the call even during a normal call.
The output form can also be displayed in real time on the liquid crystal display of the partner's sensor phone. After confirming the allocation list of sensors connected to the partner's sensor phone on the display of the sensor phone at hand, press the sensor output selection function button to set the liquid crystal display / continuous output mode, and press the acceleration button 2a with the push button. , Vibration sensor 1
By specifying a, it is also possible to display a graph of the elapsed time of the output values of these sensors. As an example, if the vibration sensor 1a and the acceleration sensor 2a constantly fluctuate, it can be seen that the other party of the call is involved in a traffic jam, and the output value of the acceleration sensor 2a is small and stable. If 1a changes periodically, it is possible to know that the other party is picking up, such as being comfortably traveling on the highway. By using the ISDN network in this way,
Compared with the analog network, much more realistic and natural communication is realized, and the psychological state and mental state of the other party can be indirectly known, which contributes to smooth communication.

In the car telephone type sensor telephone having the above structure, when the telephone is not being called, for example, when the push button (3 #) is pressed, the direction sensor 3a is selected, and the current direction can be known by voice synthesis. From, you can check the malfunction of the sensor or confirm the current direction.

[0048]

As described in detail above, the sensor telephone of the present invention is incorporated in a wireless telephone and has a plurality of sensors for detecting various kinds of predetermined information and a sensor switching circuit for selecting each sensor. A sensor output control circuit that reports the sensor output selected by this sensor switching circuit to the outside, a call control circuit that automatically responds to a call from the outside and controls the output of the sensor output control circuit, and the The sensor switching circuit is driven by a signal that uses the specific frequency selected by the call partner, and the sensor information of the selected sensor is reported to the person or the call partner or both the caller and the call partner via the sensor output control circuit. Since it is equipped with a sensor signal processing circuit, it is possible to exchange sensor information with each other while talking on the telephone, and to enable realistic communication. Can. In the case of conventional priority telephones, since the telephone is used in a fixed place, it is not necessary to inform the other party of the telephone environment, but especially with wireless telephones, the telephone environment changes variously like car telephones. As a result, the effect of realistic communication is demonstrated. Then, it becomes possible to perform bidirectional communication between the human and the sensor, and it is possible to check the malfunction of the sensor.

Since not only the hard sensor but also the soft sensor is used as the sensor, more kinds of sensor outputs can be used. Therefore, since a plurality of pieces of sensor information are confirmed by a machine and a person, the reliability of the security sensor can be significantly improved.

Further, since the signal used for sensor selection has a specific frequency as an audible frequency, mutual sensor information can be designated by the PB of the telephone, so that a special sensor designation button is unnecessary.

The sensor signal processing circuit also uses the polling method for switching, and when a sensor output above the set value appears, an alarm sound is generated or automatic dialing is performed, so the sensor operates autonomously even during a telephone call. Because
For example, if there is a risk of gas poisoning, it can be known even on the phone, and accidents can be effectively prevented. Of course, like a conventional telephone having a security function, when the sensor detects security or higher when the telephone is not used, the telephone of the registration destination can be automatically notified.

Further, since the specific frequency of the signal used for sensor selection is set to the audible frequency, mutual sensor information can be designated by the PB of the telephone, so that a special sensor designation button is unnecessary. In addition, the sensor information is transmitted urgently because the sensor interrupt is interrupted during the conversation between the speakers.

In addition to conventional home security, the sensor telephone of the present invention enables local security and personal security in a moving body such as an automobile and a place away from home for the first time. In the conventional home security system, when constructing a home security system, a large amount of wiring work was required, and the flexibility of the system was limited. In recent years, the explosive spread of cordless telephones and the case of ultra-small mobile phones have been made possible by the miniaturization of electronic components such as semiconductors.

On the other hand, the sensor parts are also being rapidly miniaturized and reduced in power consumption by the micromachining technology. The present invention has been made based on such a technical background. According to the present invention, a telephone has not only a voice terminal as a human interface but a terminal function as a natural human interface (nature interface). It will revolutionize the concept of the telephone.

Further, the sensor telephone of the present invention contributes to realization of communication with a realistic feeling. The above-mentioned embodiment is the case of the present analog telephone line, but in the case of the digital telephone line which will spread in the future, since the function of the telephone is greatly enhanced, it is impossible until now if the telephone itself has a sensor function. It is possible to exchange the real-time sensor information.

That is, the digital telephone line (ISDN
64 kbit / sec is 2 channels (B channel) and 16 kbit / sec is 1 channel (D)
Channel), and in particular, the latter channel is dedicated to data transmission. Therefore, the function of making and receiving calls is greatly enhanced, and it is possible to know the type of the partner terminal, the telephone number of the calling side, etc., which were difficult with the analog telephone line. Therefore, it is possible to directly display the built-in sensor signal on the other party's telephone without making an unnatural voice interruption response while calling. As described above, the telephone line will be digitized in the future, and the combined voice and data communication will be easily and economically realized. Therefore, the sensor telephone of the present invention has a very good affinity with the ISDN network, and can be used in the field. It is also useful for realizing sensitive communication.
