Here, the CS-IDs of the public base stations 3a and 3b, the lighting equipment 7 are turned on in advance, and the control signals for starting the air conditioner 8 and the home house 4 are sent to the PHS slave 9 in advance. Is registered, and within the range of the return time, the PHS base unit 5 is registered as a destination of the control signal, and the public base station is subjected to a position registration process accompanying the movement. When the CS-ID of the public base station 3a is recognized after the CS-ID of the public base station 3b is recognized, the lighting fixture 7,
The control signal of the air conditioner 8 is transmitted to the PHS master device 5 of the house 4, and the PHS master device 5 receives the control signal and transfers the control signal to the telecontroller 6, and the telecontroller 6 responds to the control signal by the lighting fixture. 7. A case where the air conditioner 8 is operated will be exemplified. That is, the RAM of the PHS slave 9
39 stores a CS-ID and a time zone (time range) as a control start position corresponding to a control code for a control target.

Note that a plurality of CS-Is are used as control start positions.
Although D is stored, it may be one or three or more. The setting of the time range is performed in order to prevent the processing from being executed at an incorrect time when passing through the same place many times. For example, this is because, when the user wants to operate when returning home, if the user passes through a registered location in the morning and operates, an operation different from the user's will is performed. Further, a condition such as a date and a season may be added as a condition, or another terminal may be registered as a destination.

FIG. 5 shows the contents of the remote control processing executed by the PHS slave 9 at the time of the position registration processing.

At the beginning, the nearest CS-I obtained
Wait for D to be updated as it moves (step A
01) If it is determined that the time has been updated, then it is determined whether or not the time at that time is within a preset time range (step A02).

If it is determined that the time is out of the preset time range, the process returns to the step A01.

If it is determined in step A02 that the current time is within the preset time range, then it is determined whether or not the updated CS-ID matches that of the previously registered public base station 3b. Then, only when it is determined that they match (step A03), "1" is set to the flag register F provided in the work area of the RAM 39 (step A04), and the process returns to the process from step A01 again.

Further, C updated in step A03
If it is determined that the S-ID is not that of the previously registered public base station 3b, then it is determined whether the next updated CS-ID matches that of another previously registered public base station 3a. (Step A05).

Here, if it is determined that they do not match with those of the public base station 3a, the process returns to the above-mentioned step A01. If it is determined that they match, then the flag register F provided in the RAM 39 is stored. Is set to "1" (step A0).
6).

This depends on whether or not the process in step A04 has been performed, that is, whether or not the PHS slave 9 has entered the communication range of the public base station 3a after passing through the communication range of the public base station 3b. This is for judging the moving direction of the slave unit 9, and when "1" is not set in the flag register F, the communication range of the public base station 3b is set before passing through the communication range of the public base station 3a. , So that it is determined that the vehicle is not on the way home after passing through a previously set route, and the process returns to step A01 again.

In step A06, "1" is set in the flag register F, and the public base station 3a is set within the communication range of the public base station 3b within the preset time range.
Is determined to be in the middle of returning home via a preset route due to the movement of the PHS master device 5 of the home house 4,
(Step A07), and it is determined whether or not the line is connected within a fixed ringing time (step A08).

Here, if the PHS base unit 5 does not automatically answer and the line is not connected, for example, because a response is being made by the answering machine recording function, the work area of the RAM 39 for counting the number of calls is stored. The value of the register i provided is updated by "+1" (the initial value is "0"), and the updated value of the register i holds the maximum value of the number of calls that can be arbitrarily set. After confirming that the value of the register j has not been reached (step A10), the processing from step A07 is repeated and executed again.

In this way, the automatic call to the PHS base unit 5 is performed by the number of times of the maximum register j until the line is connected. If the PHS base unit 5 still does not respond and the line cannot be connected, After the fact (for example, “Home automation is impossible”) is displayed on the display unit, the flag register F is reset to “0” to return to the initial state.
At the same time, after the value of the register i is cleared to "0" (step A13), the above-mentioned step A01 is performed again.
Return to the processing from.

In step A08, the PHS master 5
Automatically responds to the call and determines that the line has been connected, the PHS slave device 9 outputs a control signal for operating the lighting fixture 7 and the air conditioner 8 that have been preset as home appliances to be controlled. Is transmitted to the PHS master device 5 (step A11), and a signal for disconnecting the connected line is signaled (step A12). Then, as post-processing, the flag register F is reset to "0", the value of the register i is also cleared to "0" (step A13), and the process returns to the step A01 again.

In this manner, a signal for remote control can be automatically transmitted from the PHS slave 9 as a portable terminal without any special operation by the user of the PHS slave 9.

At this time, since the transmission conditions from the PHS slave unit 9 are set according to the time range and the moving direction, it is possible to surely limit unnecessary remote control under conditions other than those originally required. can do.

Next, the processing in the PHS master device 5 that has received such an automatic call from the PHS slave device 9 will be described with reference to FIG.

That is, the PHS master unit 5 is normally waiting for an incoming call (step B01), and automatically determines that there is an incoming call, and automatically connects to the line. Then, first, it is determined whether or not the call is from the PHS handset 9 based on, for example, the caller number (step B02). 9
It is determined continuously whether or not a control signal has been transmitted from (step B03).

Here, when it is determined that the call is not from the PHS slave unit 9 or that the control signal is not transmitted even if the call is from the PHS slave unit 9, the corresponding situation is determined. The processing shifts to normal incoming call processing.

When it is determined in step B03 that the control signal is being transmitted from the PHS slave 9, the control signals sequentially transmitted are held in the RAM 19 (step B04) while the PHS slave 9 performs the control. By repeating the process of determining whether or not the signal transmission is completed and determining whether or not the PHS slave 9 has disconnected the line (step B05), all of the control signals sent are held, and the PHS slave is held. The machine 9 waits for the disconnection of the line connection.

When it is determined in step B05 that the PHS slave 9 has disconnected the line connection, the PHS master 5
In step (B06), the disconnection processing is also executed (step B06), and the control signals held up to that point are collectively transferred and output to the telecontroller 6 registered in the slave unit (step B07). Is completed, and the process returns to the process of waiting for an incoming call from step B01.

The PHS slave unit 9 and the PHS master unit 5
The transmission and reception of the control signal with the line is performed after the line is once connected. However, if the control signal is transmitted and disconnected before the line is connected as UUI (user / user information), the line is not connected ( Control signals can be sent and received (without being charged).

FIG. 7 exemplifies the processing in the telecontroller 6 which receives the transfer of the control signal from the PHS master unit 5. The telecontroller 6 always waits for an incoming call from the PHS master 5 (step C01), and upon determining that there is an incoming call from the PHS master 5, receives the transferred control signal and stores it in the RAM 39. It is held once (step C02).

Next, the content of the register m provided in the work area of the RAM 39 is cleared to “0” to count the number of transmissions of the infrared signal to the home electric appliance to be controlled (step C 03), and the control is also performed. In order to grasp the previous state, each output value of the sensor corresponding to the control object, that is, the illuminance sensor of the sensor unit 58 for the lighting fixture 7 and the output value of the temperature sensor of the sensor unit 58 for the air conditioner 8 is taken, and the work area of the RAM 56 is taken. (Step C04).

Thereafter, the control signal is read out by referring to the RAM 56 based on the held control signal, and the infrared transmission / reception unit 57 is driven to emit light, thereby outputting an infrared signal corresponding to the control signal.

After outputting this infrared signal,
After waiting for a certain period of time sufficient to determine the operation state of the home appliance to be controlled, for example, 10 minutes when the air conditioner 8 is considered (step C06), the value of the register m is set to “+1”. "Update setting (step C0
7) Then, the updated value of the register m holds the maximum value of the number of infrared signal transmissions that can be set arbitrarily.
After confirming that the value of the register n provided in the work area of the AM 56 has not been reached (step C08), the output values of the sensor corresponding to the control object are fetched again in the same manner as in step C04. It is stored in the work area (step C09).

Then, by comparing each of the output values of the sensor and the output values of the sensor which were previously acquired (step C10), the home electric appliance to be controlled with respect to the transmission of the infrared signal. It is determined whether the device is operating normally (step C11).

Here, when it is determined that the home appliance to be controlled is operating normally, that is, it is determined that the output value of each sensor that has been taken has changed according to the control contents between the previous time and this time. In this case, it is determined that the remote control from the PHS slave device 9 has been successful, and the series of processes is completed as described above, and the process returns to the process from step C01 again.

When it is determined in step C11 that the home electric appliance to be controlled is not operating normally, that is, whether the output values of the respective sensors have hardly changed between the previous time and this time, or If it is determined that the remote control has changed in a direction different from the content, it is determined that the remote control from the PHS slave device 9 has failed for some reason, and the process from step C05 is executed again. An infrared signal based on a control code corresponding to the control signal is transmitted to the control target home electric appliance to check its operation.

In this way, by repeatedly executing the processing shown in steps C05 to C11 up to the number of times set in the register m, the home electric appliance to be controlled can be reliably operated based on the control signal from the PHS slave unit 9. Can be done.

In the above-described embodiment, the PHS slave 9 is used as a mobile terminal, and the PHS slave 9 detects the CS-ID of the nearest public base station 3 as a means for detecting the position.
However, this position detecting means cannot perform position registration if the communication terminal is out of the communication range of the public base station 3.

The present invention is not limited to this. For example, recently, miniaturization has progressed, and it has become possible to incorporate G into a wristwatch or the like.
PS (Global Positioning Sys)
tem) It may be realized by combining a receiver and a digital cellular phone or the like as a transmitting means, or furthermore, those functions may be built into a handy type personal computer, and many other functions may be used. Variations can be considered.

In the above embodiment, the PHS master 5
, The teleconverter and the roller 6 are formed separately, but may be formed integrally.

In addition, the present invention can be variously modified and implemented without departing from the gist thereof.
