[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 signal. In particular, a mechanical security device that uses a general subscriber telephone line can use the telephone line installed in an office or the like as it is, so installation costs for installing mechanical security are reduced, and the number of service lines at the monitoring center is reduced. It is widely used because it has the advantage of reducing capital expenditures for security companies because it requires only a short time.

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 signal. When the telephone line is connected by dialing, the above signal is transmitted to the monitoring center. At this time,
The mechanical security device transmits a connection confirmation signal from the monitoring center in order to determine the connection of the line with the monitoring center, and the mechanical security device receives the connection confirmation signal to confirm the connection of the line. In the actual machine security service, the start and the release of the machine security are performed by a security switch operated by a security contractor, and the automatic dial function is also operated in accordance with this.

For example, when the last person leaving the office operates the security switch to the security side to start security, the mechanical security device issues a preset telephone number of a remote monitoring center by an automatic dial function. Call. In response to this, when the line is connected by the operation of the automatic receiving device of the monitoring center, a connection confirmation signal is returned from the monitoring center to the machine security device side. The mechanical security device receives the connection confirmation signal, transmits its own identification signal and a security start signal to the monitoring center,
When transmission is completed, the line is released and the system stands by in a security state.

When various detectors provided in the area to be guarded detect an abnormality after the security is started, the mechanical 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. After the connection confirmation signal is transmitted and received, the mechanical security device transmits an alarm signal indicating various abnormalities and a self-identification signal to the monitoring center. Upon receiving the alarm signal and the identification signal, the monitoring center displays the property name and the type of the abnormal alarm on the display device of the monitoring center, and takes measures such as urging a guard or reporting to the fire department or police. . 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.

[0006]

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 not, an automatic dial function is provided to open the line once and repeat dialing again. 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.

[0007] However, if the telephone line is disconnected,
If the telephone line cannot be used due to the ban on the use of telephone lines by the telecommunications carrier due to the user's unpaid payment or line construction by the line maintenance company, or the user switches the telephone line from the dial pulse line to the security service company without permission. In the case of switching to a touch-tone telephone line, etc., the security start signal from the security target cannot be received by the monitoring center, and even if the last person leaving the security target turns on the security switch, the security start display is displayed at the remote monitoring center. Nasarezu, subsequent security target various detectors can not receive alarm monitoring center also detects an abnormality, security target is a problem that has been left free security state. Also, the last person leaving the security system confirms that security has started.
It is also a problem that they return without
Was.

The present invention has been made in order to solve the above-mentioned problems, and has a reliability capable of promptly and surely informing a user when a telephone line is unavailable to take a countermeasure. The purpose is to obtain a high-security mechanical guard.

[0010]

In the present invention, the display during the line communication is performed from the security start operation to the security start signal transmission . At this time , if a connection confirmation signal from the monitoring center cannot be received in response to the call , a line abnormality is displayed.

[0011]

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 last exit from which security is to be performed, and is used to start and release security, and 2 is a line provided with the security switch 1. The non-reporting notification unit 3 is a mechanical security device main unit (hereinafter, abbreviated as a main unit) installed in the security target. 31 is a control unit of a mechanical security device, 32 is an automatic dial unit for automatically dialing a remote monitoring center and transmitting various signals via a general subscriber telephone line, and 33 is a connection confirmation signal from the remote monitoring center. A line connection judging unit 34 for receiving and judging the line connection is an input / output unit between the main unit 3 and an external connection device, and the main unit 3 is constituted by portions indicated by reference numerals 31 to 34. Reference numeral 4 denotes a detector group including detectors 41 to 44 installed in the alarm target and detecting an abnormality such as intrusion, fire, gas leak and the like.

Next, the operation of the mechanical security device having the above configuration will be described with reference to the flowchart shown in FIG. The last exit person of the security object who introduced the mechanical security operates the security switch 1 provided near the last exit port of the security object to perform the operation of starting the security. In step 11, the control unit 31 determines whether or not the security switch 1 is turned on. However, the security switch 1 is turned on by the security start operation to generate a start operation signal. 34, and
It is determined that the security switch 1 is on. Step 12
Then, the control unit 31 determines whether or not the detector group 4 installed in the security object is normal. Perform an abnormal exit operation such as not turning on the light.
As a result, the last person leaving the building can see the abnormal location, for example, the detector 4
It is checked whether or not the door provided with 1 is closed. If the door is open, it is closed and the security switch 1 is started again.

If the detector group 4 is not abnormal, the controller 31
Turns on the line non-reporting unit 2 provided integrally with the security switch 1 in step 14, and causes the line non-reporting unit 2 to display that line communication is being performed. Next, at step 15, the control unit 31 activates the automatic dial unit 32 to call a remote monitoring center via a general subscriber telephone line. In response to this, the receiving device of the monitoring center (not shown) activates the automatic receiving device to connect the line, and returns a connection confirmation signal to the mechanical security device via the line. The line connection determination unit 33 receives the connection confirmation signal from the monitoring center, and transmits the line connection signal to the control unit 31.

The control unit 31 determines in step 16 whether a connection confirmation signal has been received, and if so, in step 17, causes the automatic dial unit 32 to transmit a security start signal and a self-identification signal. The monitoring center receives the security start signal and the identification signal, and displays and prints it on a CRT or a printer serving as a monitoring display means to record the security start of the security object. Next, the control unit 31 stops the display operation of the line non-notification notification unit 2. As a result, the person who finally exits confirms that the mechanical security device has reliably transmitted a signal to the monitoring center via the communication line, and the mechanical security device is in a security state.

On the other hand, if there is any abnormality in the telephone line,
Even if the call is repeated several times at fixed time intervals, the telephone line is not connected, and the line connection determination unit 33 cannot receive the connection confirmation signal in step 16. At this time, the control unit 31 changes the display of the line non-reporting unit 2 from the line communication display to the line abnormality display in step 21. This line abnormality display operates continuously unless the security switch 1 is operated to release the security. The user investigates the reason why the telephone line cannot be used and notifies the security service company that security cannot be started. The security service company that has received the notification checks the cause and restores to a state where security can be performed, or takes measures such as dispatching a security guard to perform security.

If the detector group 4 detects an abnormality after the security starts normally in step 17, the detection signal is transmitted to the control unit 31 through the input / output unit 34. Accordingly, the control unit 31 detects an abnormality in step 19 through step 18 and causes the automatic dial unit 32 to make a call in step 20 in the same manner as when security was started. When the line connection determination unit 33 receives the connection confirmation signal from the remote monitoring center and transmits the line connection signal to the control unit 31, the control unit 31 sends an alarm signal indicating an abnormality to the automatic dial unit 32 and an identification signal to the monitoring center. To send to. In this manner, security is performed until the security switch 1 is released.

Next, for example, when the first visitor comes to the security object the next morning and releases the security switch 1, the control unit 31 activates the line non-notification notification unit 2 in step 22 through step 18 to perform line communication. Is displayed, and a call is made to the monitoring center by the automatic dial unit 32 in step 23. The connection confirmation signal from the monitoring center is input to the control unit 31 as a line connection signal via the line connection determination unit 33, and the control unit 31 transmits the security release signal from the automatic dial unit 32 to the monitoring center in step 25 through step 24. Then, the self-identification signal is transmitted, the line non-reporting unit 2 is turned off, and the security is released.

However, if there is an abnormality in the line, the connection confirmation signal cannot be received in step 24, so step 2
After displaying the line abnormality for a certain period of time on the line non-notification notification unit 2 in step 6, the security is released. The user knows the line is abnormal,
Contact the security service company in the same way as when security was started. The security service company takes measures such as elucidating the cause of the line abnormality.

In the above embodiment, the line non-reporting unit 2 visually displays the line state. However, a bell or buzzer may be sounded when a line abnormality occurs.

[0020]

[Effects of the invention] As described above, according to the invention, when an abnormality occurs in the telephone line, an abnormality is displayed, so that the user can immediately know the abnormality of the line and take a countermeasure immediately.
Since the security target can be taken, it is possible to prevent the security target from being in the security-free state. Also, at the start of security, the line
Since the display during communication is performed to inform the user that the mechanical security device is operating for security start, the user is stopped until the security start operation is completed, and the security start is surely confirmed. Thus, it is possible to prevent the security target from being in the non-security state. Further, there is an advantage that when performing inspection or maintenance of the mechanical security device, the operation status can be confirmed by the display. Therefore, the reliability of the mechanical security device can be improved, and the security of the mechanical security can be enhanced, and the service to the mechanical security user can be improved.
