[Operation] The operation of the parent-child telephone system according to the present invention will be described below. Sensor 1a 2a connected to slave unit 2
When any abnormal state is detected from any or a plurality of 3a, a signal indicating some abnormality is output from the sensor output detection unit of the slave unit 2. Thereby, the wireless telephone unit 23 of the child device 2 automatically calls the telephone number of the parent device 1 stored in the ROM 25. When the base unit 1 receives the call, the telephone number of the calling side can be known from the wireless telephone unit 23 of the base unit 1 by a well-known number notification function. The automatic off-hook control unit 13 compares the telephone number of the calling side with the telephone number of the handset 2 stored in the ROM 12, and performs off-hook control on the wireless telephone unit 11 if they match. After performing the off-hook control, the wireless telephone unit 11 waits for data from the slave unit 2. When communication with the base unit 1 is established, the slave unit 2 creates data indicating that the slave unit 2 is a signal from any or a plurality of the sensors 1a 2a 3a obtained from the sensor output transmission unit 24, and the sensor output transmission unit 23 creates the data. It is transmitted to master device 1.
This is received by the wireless telephone unit 11 of the base unit 1, and the data is received by the information display control unit 14. According to the received data, the information display control unit 14 displays the information on the display unit 15 in a predetermined format. Further, the slave unit 2 receives the conversation voice from the master unit 1 and loudspeakers with a speaker. That is, by speaking an intimidating call, such as "Who is it?"
The voice is amplified from a speaker connected to the remote unit 2 at a remote location. This not only increases the probability of preventing a suspicious person from committing a criminal act, but also enhances the crime prevention effect because the voices are heard by surrounding people.

The information on the sensor 21 connected to the slave unit 2 requires only a very small amount of data. The reason is that any type of sensor 21 may be used as long as it satisfies the number of sensors 21 connected to the slave unit. For example, in the case of the sensor 21 attached to the vehicle c, the number of types is at most about 3 to 4 types. Therefore,
Even with a simple data / voice conversion process such as the well-known FSK modulation, information transmission is completed in the first one second or less even in a configuration in which the data is superimposed on normal voice. It does not hinder the sound. Of course, it may be configured to transmit separately with data modulation different from that of audio data.

[0012]

[Application Examples] The present invention is not limited to the above-described embodiments, and the following applications are also possible. (1) A plurality of slave units 2 can be provided. That is, in the above example, the vehicle c is used. However, even for a user having a plurality of vehicles c, the slave unit 2 is installed in each car, and the display unit 15 displays which vehicle is in an abnormal state. It can also be configured to make it. This example is extremely effective, for example, in a store or an exhibition hall where many vehicles are exhibited. Further, the slave unit 2 of the present invention can be installed not only in a vehicle but also in a building such as a general house h or an office o. Of course, it is also possible to make the slave unit 2 installed in the vehicle c and the slave unit 2 installed in the house h stand by with the common master unit 1, and this should be done as a construction of a total security system. (2) It is more preferable that the master unit 1 be configured to interrupt the call with priority when receiving a call from the slave unit 2 even in a normal conversation. (3) The slave unit 2 may be provided with a control interface so that the master unit 1 has a remote control function.
For example, when the slave unit 2 is provided in the vehicle c, if the door lock is configured to be controlled, the engine key is practically unnecessary. In addition, when the slave unit 2 is provided in the house h, it is convenient if functions such as control of an air conditioner and recording reservation of a VTR are provided. (4) It is more preferable that a sound collecting microphone is connected to the slave unit 2 and the surrounding situation is transmitted to the master unit 1 by voice. (5) It is more preferable that a CCD camera is connected to the slave unit 2 and the surrounding situation is transmitted to the master unit 1 as a still image or a moving image.
