Abstract

PROBLEM TO BE SOLVED: To preferentially transmit an alarm in the case that no free channel is present in a channel at the time of transmitting the alarm based on abnormality generated in a zone to be monitored to a remote monitoring device by using a communication channel. SOLUTION: This machine guard system is provided with a transmitter 3 provided with a function for transmitting the alarm to a remote monitoring device by using a telephone line when detection signals for detecting the abnormality are inputted from a sensor 1 and a connector 4 for converting a communication procedure corresponding to input signals from the transmitter and transmitting the alarm to the monitoring device through an ISDN network. In the case that the no free channel is present when the telephone number of the monitoring device is inputted from the transmitter, the connector performs the disconnecting operation of one or plural communication channels among the channels, turns them into the free channel, performs the connecting operation of the monitoring device and the communication channel by using the channel and transmits the alarm through the communication channel to the monitoring device.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention
If an abnormality such as a fire or an intruder is detected inside the
Sends an alarm to a remote monitoring center via the ISDN network
Related to a mechanical security system. BACKGROUND OF THE INVENTION In mechanical security systems, the
The sensor detects the occurrence of a fire or the presence of a person, etc.
Output. Then, the detection signal of the sensor is set in the monitoring area.
Input to the installed transmitter, and the transmitter receives the detection from the sensor.
When the output signal is input, the user sets in advance using the operation device
The security mode of the monitored area is switched between the security mode and the release mode.
Check if it is one of them. Surveillance zone in security mode
If there is, the monitoring equipment installed in the monitoring center stored in advance
Dial the phone number of the device, and when the communication line is connected,
The type of abnormality that has occurred and the knowledge assigned to each transmitter
Sends an alarm containing other information via a telephone line
You. [0003] The monitoring device installed in the monitoring center is a telephone line.
When an alert from the transmitting device is received via the line, a sound,
A supervisor at the monitoring center that receives alerts from figures, text, etc.
To inform. [0004] The above-mentioned conventional mechanical security system
The system uses a general telephone line as the communication line.
The transmitting device is a telephone or FA installed in the monitoring area.
This telephone line may be shared with communication devices such as X.
You. In this case, when the transmitting device sends the alarm,
Communication of the communication device is
The alarm cannot be transmitted until the process is completed, and the monitoring center
Because the occurrence cannot be known, response to abnormal situations is delayed.
The damage was likely to increase. [0005] In order to solve the above problem, transmission
A dedicated communication line used only for sending alarms from the device
But it ’s not only expensive,
The communication line is used when the transmitter is not sending an alarm
Communication lines cannot be used effectively
There was a problem that. Recently, ISDN (Digital
Service network) has commenced. This ISD
N basic interface (2B + D)
B channel called two information channels used for transmission
And two terminals can communicate at the same time.
I can do it. Therefore, in the above mechanical security system,
Can also use this ISDN, for example,
Communication using one B channel
If not, use another available B channel.
Alerts to monitoring devices. This
At the time of installation,
If the communication device is used as it is, the ISDN communication procedure
Is different from the communication procedure for general telephone lines.
You will need a terminal adapter to do the conversion. This tar
Connect a telephone, fax, transmitting device, etc. to the terminal adapter
Each communication device is connected to the ISDN via a terminal adapter.
Connection operation. However, transmission to this terminal adapter
In addition to equipment, telephones, faxes, personal computers, etc.
May be connected to two or more communication devices. in this case,
When the transmitting device sends an alarm, for example, a telephone and a facsimile
Is communicating and two B channels are already in use
If the communication is
An alarm is transmitted until one of the B channels is released.
The monitoring center cannot detect the occurrence of an error
As a result, the response to abnormal situations may be delayed and the damage may increase
was there. [0008] The present invention has been made in view of the above problems.
Yes, the occurrence of anomalies in the monitored area is confirmed by a remote monitoring device.

Claims (1)

Claims: 1. A sensor for outputting a detection signal when an abnormality is detected in a monitored area, and when a detection signal from the sensor is input, an alarm is issued to a remote monitoring device using a telephone line. In a mechanical security system having a transmitting device having a function of transmitting, and a connecting device for converting a communication procedure according to an input signal from the transmitting device and transmitting an alarm to a monitoring device via an ISDN network, When the detection signal from the sensor is input, the telephone number of the monitoring device is output to the connection device, and when the response signal from the connection device is input, the identification information and the information indicating the type of abnormality that are given to each transmission device in advance are input. An alarm including the following is output to the connection device, and after outputting the alarm, a disconnection signal is output to the connection device. If there is no channel, after disconnecting one or more communication lines among the channels to make it an empty channel, a connection operation of the communication line with the monitoring device is performed by using the channel, and the connection with the monitoring device is performed. When the communication line is connected, a response signal is output to the transmission device, and when an alarm from the transmission device is input, the alarm is transmitted to the monitoring device via the communication line, and when a disconnection signal from the transmission device is input, the monitoring is performed. A mechanical security system for performing a disconnection operation of a communication line with a device. 2. The connection device stores the priorities of communication devices other than the transmission device in advance, and if there is no available channel when the telephone number of the monitoring device is input from the transmission device, Of the communication devices that are communicating using the communication device, the communication line of the channel used by the communication device of lower priority is disconnected to make it a free channel, and then the monitoring device is used by using the channel.
