[0001]

[Industrial application field] This invention installs various security detectors in offices and stores, starts security at a remote monitoring center, and automatically releases information such as release signals and alarms to general subscriber telephone lines with an automatic dial function. More particularly, the present invention relates to a mechanical security device having a function of notifying a user that the line is disconnected when a general subscriber telephone line is unavailable.

[0002]

2. Description of the Related Art Generally, there is known a mechanical security service in which various detectors for detecting abnormalities such as an intruder and a fire are installed in an office or a store, and these abnormalities are monitored at a remote monitoring center. The mechanical security device used for the mechanical security service uses a general subscriber telephone line or a dedicated line as a means for transmitting a security start signal, a release signal, and an alarm. In particular, for mechanical security devices that use general subscriber telephone lines, the telephone lines installed in offices and the like can be used as they are, reducing the installation work costs for introducing mechanical security and, in addition, the number of incoming lines at the monitoring center is exclusive It is widely used because it has the advantage of reducing capital investment by security companies because it requires less than lines.

As described above, a mechanical security device using a general subscriber telephone line has an automatic dial function, and automatically transmits a telephone number of a remote monitoring center when transmitting a security start signal, a release signal or an alarm. When the telephone line is connected by dialing, the above signal is transmitted to the monitoring center. The mechanical security device has a line connection determination function for determining a line connection with the monitoring center. As means for judging the line connection of these line connection judgment functions, it is common to use the inversion of the polarity at the time of line connection of a telephone line.

[0004] In the actual machine security service, the start and the release of the machine security are performed by a security switch operated by a contractor of the security destination, and the automatic dial function is also operated accordingly. For example, when the last person leaving the office operates the security switch to start security, the mechanical security device calls a preset telephone number of a remote monitoring center by an automatic dial function.

[0005] In response to this, when the line is connected by the operation of the automatic receiving device of the monitoring center, the line connection determination unit of the machine security device determines the connection of the line, the self-identification signal of the machine security device and the security start. A signal is transmitted to the start center, and when the transmission is completed, the line is opened and the apparatus stands by in a security state.

[0006] When various detectors provided on the security object detect an abnormality after the security starts, the machine security device activates the automatic dial function and calls the monitoring center again as in the case of the security start, and the line is connected and the machine is connected. The security device transmits an alarm indicating various abnormalities and a self-identification signal to the monitoring center. Upon receiving the alarm and the identification signal, the monitoring center displays the name of the security destination and the type of the alarm on the display device of the monitoring center,
The security officers are dispatched and the police and fire departments are notified. Also, in the case of security release, the automatic dial function is activated and a release signal and an identification signal are transmitted to the monitoring center as in the case of security start.

[0007]

As described above, a conventional mechanical security device using a general subscriber telephone line makes a call for a fixed time until a call is actually made when a remote monitoring center is called, and the line is connected. If it is not, a network control function (automatic dial function) that opens the line once and repeats dialing again is provided. This function is effective as long as the machine security device and the automatic call receiving device of the monitoring center are normal when the telephone line is normally usable.

However, if the telephone line is disconnected,
If the telephone line cannot be used due to a ban on the use of the telephone line by the telecommunications carrier due to unpaid user charges or the line construction by the line maintenance company, or the user dials the telephone line without contacting the security company. For example, when the security switch signal is changed to a touch-tone telephone line, the security start signal from the security target cannot be received by the monitoring center, and even if the last person leaving the security system turns on the security switch, the security start signal is displayed at the remote monitoring center. However, there is a problem that the monitoring center cannot receive an alarm even if various types of detectors to be guarded detect an abnormality thereafter, and the guarded object is left unguarded.

[0009] This invention has been the Do to solve the above problems, check whether the phone line is normal
It is another object of the present invention to provide a highly reliable mechanical security device capable of promptly notifying a user when a telephone line is abnormal and preventing an unguarded state of a security target.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of a mechanical security device according to this embodiment, wherein 1 is a security switch provided near the final exit of a security object and operates to start and release security, and 2 is a machine installed in the security object. It is the main body of the security device, and the main body 2
, An input / output unit 21 for communication with an external connection device, a network control unit 22 for automatically dialing a telephone number of an NTT time signal service and a telephone number of a remote monitoring center, and transmitting various signals via a general subscriber telephone line. , A line connection determination unit 23 for determining whether or not a telephone line with an NTT time signal service and a remote monitoring center is connected, and a control unit 24.

Reference numeral 3 denotes detectors 31 to 31 installed in the security object.
36, a group of detectors for detecting abnormalities such as intrusion, fire, and gas leak. Reference numeral 4 is connected to the detector group 3, and a display unit for displaying which detector has detected an abnormality when an abnormality is detected is provided. It is a speaker that outputs the sound of the time signal service.

Next, the operation of the mechanical security device having the above configuration will be described with reference to the flowchart shown in FIG. First, the last exit person to be guarded operates the security switch 1 provided at the last exit gate to be guarded, and performs an operation for starting security. In step 11, the control unit 24 determines whether or not the security switch 1 is on. However, the security switch 1 is turned on by the security start operation to generate a security start operation signal, and the control unit 24 transmits this signal to the input / output unit. 21 and the security switch 1
Is determined to be on.

In step 12, the control unit 24 determines whether or not the detector group 3 installed in the security object is normal. If it is abnormal, in step 13, security is not started and the security switch 1 is provided on the security switch 1 (not shown). Abnormal exit operation such as turning on the indicator lamp
Notify by display. In response to this, the final exit person releases the security switch 1 and checks the display unit 4 which detector of the detector group 3 in the security target indicates an abnormality. For example, if the detector 31 provided in the window indicates an abnormality, the window is closed and the security switch 1 is again operated to start security.

If the detector group 3 is not abnormal, the control unit 24
Causes the network control unit 22 to dial the NTT time signal service 117 at step 14. Next, step 1
In step 5, the line connection determination unit 23 confirms whether or not the line is connected to the NTT time signal service, and transmits a line connection confirmation signal to the control unit 24 when the line is connected. When receiving the line connection confirmation signal, the control unit 24 outputs the sound of the time signal service to the speaker 5 provided at the final exit through the input / output unit 21 in step 16. As a result, the last exit can confirm that there is no abnormality in the line. Then, when the voice is output for a predetermined time, for example, 15 seconds, the network control unit 22
To release the line.

Next, at step 17, the control unit 24 causes the network control unit 22 to dial the telephone number of the remote monitoring center. Upon receiving the line connection confirmation signal from the line connection determination unit 23 in step 18, the control unit 24 causes the network control unit 22 to transmit its own identification signal and security start signal to the monitoring center in step 19, and releases the line. Stand by in security.
The remote monitoring center that has received the security start signal and the identification signal displays and prints on a monitoring CRT or printer and starts monitoring.

In step 20, it is determined whether or not the security switch 1 is turned on.
It is determined whether or not has detected an abnormality. Upon receiving the abnormal signal from the detector group 3 via the display unit 4 and the input / output unit 21, the control unit 24 in step 22 causes the network control unit 22 to dial the telephone number of the remote monitoring center, and When the line connection is confirmed by the line connection confirmation signal from 23, the network controller 22 is caused to transmit its own identification signal and alarm signal. The remote monitoring center receives the identification signal and the alarm signal, detects what kind of abnormality has occurred in which security target, and prints an alarm display on a CRT or printer.
Take security measures such as dispatching security personnel to the security target or contacting the police or fire department.

Also, for example, when the first visitor to be guarded the next morning comes and the security switch 1 is released, step 2
At 0, the control unit 24 receives the security release operation signal of the security switch 1 via the input / output unit 21, and at step 23, causes the network control unit 22 to dial the telephone number of the NTT time signal service as in the case of starting security. When the line connection confirmation signal from the line connection determination unit 23 is received by the dial within a predetermined number of times in step 24, the signal is output to the speaker 5 for a certain period of time in step 25, and the network control unit 22 is released. In step 26, the network control unit 22 is made to dial the telephone number of the monitoring center. In step 27, when the line connection confirmation signal is received from the line connection determination unit 23, in step 28, the network control unit 22 sends its own identification signal and security release. A signal is transmitted to the monitoring center, and the security is released.

The operation so far has been performed in a state where the general subscriber telephone line is usable. Next, a case where the telephone line is in an unusable state when security is started will be described.
In this case, in steps 15 and 29, the line connection determination unit 23
Is used to check whether the line is connected.
Dial the first phone number and see if the line is connected
To monitor. However, after a certain period of time after dialing
Since the line is not connected, the line is opened. afterwards,
Even if the same operation is repeated a predetermined number of times, connection cannot be confirmed. For this reason, the last exit person cannot hear the time signal voice from the speaker 5, and can confirm that security has not been started. The last exiter operates the security switch 1 to the security release side at step 30 to notify the security company that security is not started. Upon receiving this notification, the security company takes measures such as directing the security personnel to the security destination and pursuing the cause of the line abnormality.

If there is a line error when the security is released
Also, the same operation as at the start of security may be performed. Sand
That is, in steps 23 and 24, even if the network control unit 22 dials the telephone number of the NTT time signal service a predetermined number of times or more, the connection is not established, and the user cannot hear the time signal service.
In addition, security cannot be entered because security is not released. In this case, the user contacts the security company to request a predetermined operation, and the security company that has received the notification promptly dispatches a security guard to reset the main body 2 to put the security in a security released state (step 3).
1).

As described above, in the above-described embodiment, when the line is abnormal, the line is not connected even if dialing the time signal service a predetermined number of times, and no time signal voice is output to the user.
Thus, the user can determine the line abnormality.
When a line is not connected due to a line abnormality, a message indicating that the line cannot be connected may be displayed on the security switch 1.

[0023]

[Effect of the invention] As described above, according to the invention, security is opened.
Automatically outputs an audio signal when an incoming call is received at the beginning. Dials the first telephone number of the call destination, and allows the user to hear the audio. Security can be prevented, and prompt action should be taken in the event of a line failure.
Therefore, the reliability of the security of the machine can be improved. In addition, since the telephone information service of a telecommunications carrier usually has three digits for dialing, the dialing time is short, so that the waiting time for the user can be shortened. Poor connection is less likely to occur. Further, when the telephone information service is a time signal service, the user can confirm the time of security start .
