This communication control device is generally configured to be able to control various electric appliances by connecting to a so-called "dedicated line" which is provided separately from a home telephone. In addition, the communication control device may be attached in parallel to the telephone line of the home telephone, if necessary.

When the communication control device is installed in parallel with the home telephone, the control method of the communication control device is as follows.
There is a control method based on the number of phone calls. Specifically, for example, it is a method of setting a predetermined number of calls in advance and starting the control when the number of calls is reached, or performing a predetermined operation after the number of calls is reached and then starting the control. .

[0005]

However, the communication control device connected in parallel to the home telephone as in the above-mentioned conventional technique has the following problems.

Most of the currently popular household telephones have an automatic incoming call function for operating an answering machine and a fax machine. The automatic call receiving function is generally controlled based on the number of calls.

Therefore, when a telephone having such an automatic incoming call function and a communication control device are mounted in parallel, each is controlled by the number of calls,
One of the telephone (automatic call reception function) and communication control device,
Alternatively, there is a problem in that both cannot function properly. In other words, there is a problem in that a device with a small number of calls is connected to a telephone line first, so that a device with a large number of calls cannot be used.

Therefore, the present invention has been made in order to solve the above-mentioned problems in the prior art. In the state where the automatic reception function is provided in parallel with the home telephone, the automatic reception function is provided. An object of the present invention is to provide a communication control device capable of controlling a controlled device via a telephone line without damage. Another object of the present invention is to provide a remote security system using such a communication control device.

[0009]

According to a first aspect of the present invention, there is provided a communication control device connected in parallel to a telephone line to a telephone line, which is electrically connected to a controlled device and is connected to the telephone line. Of the telephone line is monitored by detecting the voltage change state of the telephone line. When the telephone and the telephone line are in the off-hook state, the line state is monitored and the telephone line is input based on the input of the password signal. Then, at least one of transmission and reception of a signal is performed with the controlled device to control the controlled device via the telephone line, and the telephone and the telephone line are connected to each other. Is on-hook, the number of calls is monitored, and when the number of calls reaches a predetermined number of first calls, the telephone line goes off-hook and the password signal is input. To perform the control of the controlled apparatus through the telephone line, and wherein at least one of transmission and reception of signals at between the controlled device is performed. Here, the "telephone" is a concept that includes not only a telephone that only makes general calls but also a telephone with an automatic answering function such as an answering machine function, a fax function, and a fax machine.

According to the communication control device thus constructed, even if the telephones connected in parallel go into the off-hook state first, the line state is monitored (polarity and DTMF are monitored). When a password signal (for example, DTMF) is input, the telephone line can be brought into an off-hook state, and the controlled device can be properly connected via the telephone line and the communication control device. Control can be performed. On the other hand, since this communication control device also monitors the number of calls, it can be put into the off-hook state with respect to the telephone line after the lapse of the predetermined first number of calls, and the password signal can be input. By confirming, it is possible to appropriately control the controlled device via the telephone line and the communication control device. That is, according to the first aspect of the present invention, even when the telephone and the communication control device are connected in parallel to one telephone line, the functions of both devices (the telephone and the communication control device) are not impaired. Thus, it is possible to obtain a communication control device capable of controlling the controlled device via a telephone line.

A second aspect of the present invention is a communication control device connected to a telephone line in parallel with a telephone line,

Based on the off-hook state with the telephone line, it becomes possible to start control of the controlled device via the telephone line,
When the control of the controlled device is terminated in accordance with the reception state of the DTMF signal and the call progress tone and the telephone and the telephone line are in the on-hook state, the number of calls due to the reversal of the line polarity is monitored, and the number of calls is determined. Has entered a predetermined number of first calls and is in an off-hook state with the telephone line, the control of the controlled device via the telephone line can be started based on the input of the password signal by the DTMF signal, and the DTMF signal can be started. Also, the control of the controlled device is terminated according to the reception state of the call progress tone.

In the communication control device thus constructed, the DTM signal, the call progress tone, and the line polarity are monitored by monitoring the DTMF signal regardless of whether the telephone is off-hook or on-hook.
The control of the controlled device can be started based on the password signal by the F signal and the monitoring state of the line polarity.
The control of the controlled device is ended according to the reception state of the MF signal and the call progress tone. Therefore, according to the second aspect, as in the case of the first aspect, even when the telephone and the communication control device are connected in parallel to one telephone line, any device (the telephone and the communication control device) is connected. It is possible to obtain the communication control device capable of controlling the controlled device via the telephone line without deteriorating the function of). According to the second aspect, the communication control device can be automatically put into the on-hook state by monitoring the DTMF signal and the call progress tone.

Further, in the first and second aspects of the present invention, when the telephone has an automatic incoming call function, the first call count is the second call determined for controlling the automatic incoming call function. A configuration in which the number is set larger than the number of times is preferable. Here, the "automatic incoming call function" refers to a function for automatically off-hooking a telephone line in order to operate an answering machine, a fax machine, or the like.

According to this preferred configuration, the first call count is set to be larger than the second call count, so that the answering machine or the like can be controlled based on the automatic call receiving function before the communication control device. It will be started. That is, the telephones connected in parallel are first in the connected state (off-hook state), and the communication control device is in a state where line monitoring is performed. That is, it is possible to use an answering machine or the like based on the automatic call reception function of the telephone, and since the line monitoring state is set, it is possible to control the controlled device via the communication control device by inputting the password signal. . Therefore, according to this preferable configuration, even if the home telephone having the automatic incoming call function is provided in parallel, the controlled device can be controlled via the telephone line without impairing the automatic incoming call function. It is possible to obtain a communication control device capable of performing the above. With such a configuration, even if a telephone having an automatic incoming call function and forgetting the setting such as an answering machine occurs,

The polarity monitoring unit 124 is configured to monitor the state of polarity of the telephone line L. This telephone line L is
In the on-hook state, the first line L1 held at the ground voltage and the second line L2 held at a predetermined voltage (for example, −48V) are used. Then, when a ringing tone is output from the exchange (when a call is received), the polarities of the first line L1 and the second line L2 are reversed, and when the off-hook state occurs (for example, when the handset is picked up), the first line is again set. When the line L1 and the second line L2 are reversed in polarity and then go into an on-hook state (for example, when the handset is dropped), the first line L1 and the second line L2 remain as they are, and the telephone line L The connection status is released. In addition, as described above, when receiving a call via the telephone line L,
When the ringing tone is ringing, the polarity monitoring unit 1

As the data recorded in the setting recording unit 125, there are telephone numbers of places to be notified via the telephone line L (for example, telephone numbers at three places), and the telephone line L is set off-hook on the communication control device 12 side. The number of calls set in (corresponding to the "first number of calls" of the present invention) or a password (predetermined DTMF) required for remote control of this system via the telephone line L, etc. .

FIG. 2 shows a flowchart for controlling the remote security system according to the first embodiment of the present invention from a remote location using a mobile phone or the like.

In the system according to this embodiment,
When a call is received through the telephone line L, that is, it is determined that there is a ringing tone in step S201 (S201).
"Yes"), it is determined whether or not the telephone set 13 connected in parallel to the telephone line L is in the off-hook state (step S202). No incoming call (S20
In No. 1), the process of S201 is repeated. Here, "the telephone 13 goes off-hook" means that the householder actually picks up the handset of the telephone 13 and the answering machine function of the telephone 13 (corresponding to the "automatic incoming call function" of the present invention) is activated. It is possible that The answering machine function generally starts operating based on a preset number of calls. Here, the number of calls when the operation of the answering machine function starts (corresponding to the “second number of calls” of the present invention) is the predetermined number of calls set to put the communication control device 12 described later into the off-hook state. It is set to a value smaller than (corresponding to the “first call count” of the present invention).

When the telephone set 13 is not in the off-hook state ("No" in S202), the ringing tone is counted by using the polarity monitoring section 124 (step S203).
It is determined whether or not the ringing tone has reached a predetermined number of calls (corresponding to the “first number of calls” of the present invention) recorded in the setting recording unit 125 (that is, the number of calls is monitored). (Step S204). If the ringing tone has not reached the predetermined number of calls ("N" in S204)
o ”), the process proceeds to the process of S202 again, and if it has reached (“ Yes ”in S204), the communication control device 1
2 goes off-hook (telephone line L and communication control device 1
2 is connected) (step S205), and whether or not a password has been input is determined using the DTMF control unit 122 or the like (step S206). Here, DTMF
The signal obtained via the control unit 122 and the setting recording unit 12
If the main control unit 121 performs a process of comparing and examining the signal recorded in No. 5 with the result that it is determined that the recorded password is properly input (“Yes” in S206). Next, the processing from step S211 is performed. Then, if the password is not properly input (no password is input or the input signal is different) (“No” in S206), the processes in and after step S213 are performed. S211 and S21
The processes after 3 will be described later.

When the telephone set 13 is in the off-hook state in the process of S202 ("Yes" in S202)
The telephone 13 connected in parallel to the telephone line L is ready for use (step S207). As described above, it is considered that the off-hook state occurs when a family member or the like picks up the handset or when the answering machine function starts to operate. In the present embodiment, the DTMF control unit of the communication control device 12 is used even when the parallel telephone 13 is in the off-hook state (especially when the answering machine is activated). 1
22 and the polarity monitoring unit 124 monitor the line status of the telephone line L, the telephone 13 having an answering machine function.
Even when the communication control device 12 and the communication control device 12 are connected in parallel, the respective devices can be appropriately operated.

In other words, in the present embodiment, in the state where the parallel telephone set 13 can be used, the state of the telephone line L and whether or not the password is input are determined by the DTMF.
When it is determined using the control unit 122, the CPT control unit 123, the polarity monitoring unit 124, and the like (step S208), and the password is not properly input (no password is input or the input signal is different) (in S208). "No"), it is determined whether or not the parallel telephone set 13 is in use (step S210), and if it is in use ("No" in S210), the process proceeds to step S207 again and the use is ended. If completed (“Yes” in S210), S21
The processes after 3 are performed. In addition, when it is determined that the password is properly input (“Yes” in S208)
The communication control device 12 is in the off-hook state (the telephone line L and the communication control device 12 are connected) (step S20).
9), and then the processing from S211 is performed.

In step S211, the telephone line L
Via an external mobile phone or the like and the communication control device 12
Since and are properly connected (off-hook state), the remote security system according to the present embodiment is in a state in which various controls can be started using a mobile phone or the like (S211). Specifically, using a mobile phone, etc., instructions for starting and ending the operation of the system, detection of the current state of the security area, change of operation time / time, registration / confirmation / change / deletion of alarm notification destination, Also, the password can be changed.

Then, after the use of the parallel telephone 13 is finished ("Yes" at S210), various controls are finished by using the portable telephone or the like (step S21).
2) After that, the ring back tone counter (not shown) is reset (step S213), and the connection state (closed state) of the telephone line 13 is released (so-called on-hook state) (step S214). The ring tone counter is
It is provided within the main control unit 121 or to be connected to the main control unit 121.

The remote security system according to this embodiment is
It is constructed and functions as shown in FIGS. 1 and 2 above.
Specifically, when the detection unit 11 detects an abnormality in the security area (occurrence of an intruder or the like), the setting recording unit 12 is preset.
The contact place recorded in 5 is notified via the communication control device 12 and the telephone line L, and the communication control device 12 and the detection unit 11 can be externally controlled as necessary. Therefore, according to the present embodiment, it is possible to recognize an abnormality in the security area, control a device installed in the security area, and the like while being in a remote place, which provides higher convenience and user convenience. The system can provide safety.

Further, the communication control device 12 constituting the present system is connected to the telephone line L in parallel with the telephone set 13. However, according to the above embodiment, the communication control device 12 is connected.
However, since the line status and the number of calls can be monitored, the remote security system can be configured without impairing the functions of the telephone set 13 and the communication control device 12. Specifically, according to the present embodiment, even if the telephones 13 connected in parallel are first connected to the telephone line L (when they are in the off-hook state), the communication control device 12 sets the line. Since the state is monitored, if the password signal is properly input, the communication control device 12 and the telephone line L are in an off-hook state, and the detection unit 11 and the like can be controlled. Further, according to the present embodiment, on the other hand, since the number of calls is also monitored, the communication control device 12 can be operated by elapse of the predetermined first number of calls.
The telephone line L and the telephone line L can be brought into an off-hook state, and the password signal can be input to control the detection unit 11 and the like. That is, according to the system of the present embodiment, the telephone 13 and the communication control device 12
Even if and are connected in parallel to one telephone line L,
Without impairing the functions of any of the devices 12 and 13, it is possible to easily check the abnormality of the security area and the like from a remote place by controlling the detection unit 11 and the like via the telephone line L.

Further, in the above embodiment, when the telephone set 13 connected in parallel to the telephone line L has an answering machine function, the telephone line L is more than the number of calls to activate the answering machine function. And communication control device 12
The number of calls to connect (and go off-hook) is set to a higher number. Therefore, according to the present embodiment, when the answering machine function of the telephone set 13 is appropriately set, the telephones connected in parallel so that the control of the answering machine function is started before the communication control device 12. 13 is in a connected state (off-hook state), and the communication control device 12 is in a state in which line monitoring is performed. That is, the answering machine function of the telephone 13 can be used, and since the line monitoring state (the state of monitoring the polarity and DTMF) is used, if the password signal is input, the communication control device 12 is used. It is possible to control the detection unit 11 and the like. Therefore, according to the present embodiment, even when the communication control device 12 is provided in parallel with the telephone set 13 having the answering machine function, the detecting unit 11 is provided via the telephone line L without impairing the answering machine function. It is possible to obtain a remote security system capable of controlling the vehicle and appropriately grasping the status of the security area from a remote place. When the answering machine starts to operate first and then the control of the communication control device 12 is started, the answering machine performs a predetermined operation based on the setting unique to the answering machine. In other words, for example, when it is set to perform “recording” for a predetermined time, regardless of the control state of the communication control device 12,
After a lapse of a predetermined time, it operates to stop recording and disconnect the line (on-hook).

Further, in the present embodiment, even if the setting is forgotten on the telephone set 13 having the answering machine function, the number of calls becomes a predetermined number (corresponding to the "first number of calls" of the present invention). At this stage, the telephone line L and the communication control device 12 are connected (in an off-hook state), and it is possible to determine whether or not the password signal is input by monitoring the line state. The input can control the system using the communication control device 13.

Second Embodiment Next, a second embodiment of the present invention (corresponding to the “second aspect” and the “fourth aspect” of the present invention) will be described. FIG. 3 shows a flowchart for controlling the remote security system according to the second embodiment of the present invention from a remote location using a portable telephone or the like.
Note that, also in the present embodiment, the basic configuration thereof is the same as that of the first embodiment, and therefore, in the following description,
Refer to the schematic block diagram of FIG. 1 as needed.

In the system according to this embodiment,
When a call is received via the telephone line L, that is, when it is determined that there is a ringing tone (incoming call) in step S301 (“Yes” in S301), telephones connected in parallel to the telephone line L. It is determined whether 13 is in the off-hook state (step S302). When there is no incoming call (“No” in S301), the process of S301 is repeated. Here, as the case where the “telephone 13 goes off-hook”, as described above, the case where the family member actually picks up the handset of the telephone 13 and the telephone 1
It is considered that the answering machine function of No. 3 (corresponding to the "automatic incoming call function" of the present invention) operates. The answering machine function generally starts operating based on a preset number of calls. Here, the number of calls when the operation of the answering machine function starts (corresponding to the “second number of calls” of the present invention) is the predetermined number of calls set to put the communication control device 12 described later into the off-hook state. It is set to a value smaller than (corresponding to the “first call count” of the present invention).

When the telephone set 13 is in the off-hook state in the processing of S302 ("Yes" in S302).
, The telephone 13 connected in parallel to the telephone line L becomes usable (step S310). As described above, it is considered that the off-hook state occurs when a family member or the like picks up the handset or when the answering machine function starts to operate. In this embodiment, the DTMF control unit 12 of the communication control device 12 is used even when the parallel telephone 13 is in the off-hook state in this way.
2. Since the CPT control unit 123 and the polarity monitoring unit 124 monitor the line state of the telephone line L, even if the telephone 13 having the answering machine function and the communication control device 12 are connected in parallel, The device can function properly.

That is, in the present embodiment, in the state where the parallel telephone set 13 can be used, the state of the telephone line L and whether or not the password is input are determined by the DTMF.
The determination is made using the control unit 122, the CPT control unit 123, the polarity monitoring unit 124, and the like (steps S311 and S31).
3) If the password is not properly entered (no password is entered or the input signal is different) (S3)
If the parallel telephone 13 is in use (step S312), it is in use (S3).
If it is “No” in 12, the process proceeds to S310 again, and if the use is completed (“Yes” in S312).
s "), and the processing from S319 onward is performed. If it is determined that the password has been properly input (“Yes” in S313), the communication control device 12 is put into the off-hook state (the telephone line L and the communication control device 12 are connected).
(Step S314), and then the processes of S315 and thereafter are performed.

In step S315, the telephone line L

Since and are properly connected (off-hook state), the remote security system according to the present embodiment is in a state in which various controls can be started using a mobile phone or the like. Specifically, the communication control device 12 (of the DTM
The F control unit 122) determines whether or not the appropriate DTMF signal is received based on the operation from the mobile phone or the like (S315), and receives the DTMF signal (S3).
If the DTMF signal is appropriate, the command processing is performed according to the signal (step S316). When the DTMF signal is not received (“No” in S315), it is determined whether or not there is no sound for a fixed time (for example, 30 seconds) (step S31).
7) If there is no sound for a certain period of time ("Yes" in S317)
s ”), the processes from step S319 onward are performed.
When the silent time has not reached the certain time (“No” in S317), the CPT control unit 123
It is determined whether or not the (call progress tone) signal is received (step S318), and if the CPT signal is received ("Yes" in S318), the step S is performed.
If the processing from 319 onward is performed and the CPT signal is not received (“No” in S318), step S315 is performed.
The subsequent processing is performed again. The processing after S319 will be described later.

By the way, "command processing" performed in S316 means the start of system operation, the detection of the current state of the security area, the operation time by the transmission of various signals (DTMF signals) using a mobile phone or the like. -It is a process of issuing commands such as time change, alarm notification destination registration / confirmation / change / deletion, and password change. For example, the command processing is performed by an input such as "** # ...". Here, the part of "** #" is the command part, and the part after "#" is the data part. The number of digits of the command is changeable. In this command processing, the command processing for the detection unit 11 is started when the reception of the command in the communication control device 12 is completed.

Further, the "password input" performed in S307 and S313 is performed by inputting "**** xxx" or the like. Here, "**" represents the command to enter the password, and "*" and the following "x"
"XXXX" represents the entered password. That is, in the communication control device 12 according to the present embodiment,
After the reception of the 6-digit information is completed, the main control unit 121
At S307, it is determined whether the password matches the password recorded in the setting recording unit 125 (S307, S).
313).

Then, the DTMF control unit 122 and the CP
Depending on the status of each signal (DTMF signal, CPT signal) monitored by the T control unit 123, S308, S30
In step S319 performed after 9, S312, S317, and S318, the ring back tone counter (not shown) is reset (S319). Next, after resetting the ring back tone counter, the connection state (closed state) of the telephone line 13 is released (so-called on-hook state) (step S320). The ring back tone counter is provided to be connected to the main control unit 121 or to the main control unit 121 as in the first embodiment.

In the CPT control unit 123, a dial tone (for example, a continuous sound of 400 Hz) on the telephone line L, a ringing tone (for example, a sound of 400 Hz is modulated at 16 Hz or 20 Hz, sounds for 1 second and repeats for 2 seconds without sound), And a busy tone (for example, a sound of 400 Hz is 5
Sounding for 00 ms and repeating silence for 500 ms) is being monitored. Then, in S309, the CPT signal is received by continuously emitting the dial tone for 3 to 5 seconds or by receiving the busy tone (two tones) 3 to 5 times (about 3 to 5 seconds). It is judged that they are doing.
Further, in S315, by receiving the busy tone (two-to-sound) 3 to 5 times (about 3 to 5 seconds), the CP
It is determined that the T signal is being received.

As described above, the remote security system according to this embodiment is constructed and functions as shown in FIGS. 1 and 3 described above.

24, the DTMF signal, the CPT signal, and the line polarity are monitored, and a simpler control system is realized by appropriately using the monitored various signal information. That is, according to the present embodiment, when the telephones 13 connected in parallel go off-hook and the line is connected, as a general rule, the exchange of voice signals is started. If a signal necessary for control (DTMF signal) is input, the line between the telephone line L and the communication control device 12 is connected (off-hook), and the predetermined detection unit 11 is controlled. In addition, even if the off-hook state is entered, if the signal necessary for controlling the communication control device 12 is not input (there is no DTMF signal and the CPT signal), the line between the telephone line L and the communication control device 12 Is disconnected (goes on-hook), and the communication control device 12 returns to the monitoring state of the DTMF signal and the CPT signal. Further, even if the telephones 13 connected in parallel are in the on-hook state, according to the present embodiment, the signals necessary for controlling the communication control device 12 using the DTMF control unit 122 and the polarity monitoring unit 124. If (DTMF signal, ringing tone count signal) is obtained, the line between the telephone line L and the communication control device 12 is connected (off-hook) according to the condition (predetermined number of ringing tones, proper password input), Control of the predetermined detection unit 11 is performed. Then, after the off-hook, if there is no input of a signal necessary for controlling the communication control device 12 (DTMF), as described above.
If there is no signal and there is a CPT signal), the line between the telephone line L and the communication control device 12 is automatically disconnected (becomes on-hook), and the communication control device 12 receives the DTMF signal and the C signal.
It returns to the monitoring state of the PT signal.
