[Technical background of the invention]

For example, in accommodation facilities or halls that accommodate a large number of people, it is mandatory to install fire alarms at predetermined intervals for fire prevention and early detection. Such fire alarms can be monitored in a central monitoring room, and when a fire alarm is detected, it sounds an emergency bell or buzzer to alert people near the fire alarm that a fire has occurred. At the same time, notify the central monitoring room of the occurrence of a fire. The lifeguard immediately shakes the phone to the fire department and dials 119 to notify them of the outbreak of a fire.After confirming the status of the fire, the lifeguard immediately calls all areas of the building to evacuate depending on the situation. Activate the fire alarm to issue an alarm.

[Problems to be solved by the invention]

To contact the fire department, etc., call 119 as mentioned above.
Methods are used to connect by dialing a telephone number or by using a dedicated line, but when reporting by telephone, there is a high chance of incorrect numbers occurring due to the rush, especially in places such as large accommodation facilities that have extension telephone equipment. Unless you dial O, you cannot communicate with the outside world, and if you forget this point, your phone will not connect, causing delays in reporting. In addition, when using a regular telephone line or a dedicated line, unlike telephone reporting, there are no mistakes in numbers, but there is a drawback that it is not possible to make a call if the source of the fire is close or if the line is damaged.

Detectors for gas leaks or electrical leaks are also provided, and it is desirable that the operation of these detectors be immediately reported to the gas company or electric power company.

The purpose of the present invention is to use a simple configuration that allows a fire alarm, etc. that detected the fire to directly notify the fire department by telephone when a fire occurs, and if telephone notification is not possible, a nearby To provide an automatic alarm monitoring system that can make a report and make a report using a nearby telephone line.

[Means for solving problems]

The automatic alarm monitoring system of the present invention includes a control unit that detects the activation of an automatic alarm and outputs an activation signal, a control unit that outputs the activation signal of the control unit together with a code signal that identifies the installation location of the automatic alarm, and an activation signal of the automatic alarm. A radio unit that transmits signals and code signals using weak radio waves, a reporting means that is electrically connected to the control unit and that automatically reports the operating signals and code signals to the monitoring headquarters via a telephone line, and a central processing unit that is connected to the telephone line and converts the notified activation signal and code signal into readable information; and a display unit that displays information from the central processing unit, central control means for transmitting a confirmation signal to the reporting means by dialing a telephone number corresponding to the telephone number; When the confirmation signal is not transmitted to the reporting means, the control unit transmits an activation signal using weak radio waves to nearby radio units in a preset order, and the nearby radio units that receive this activation signal transmitting the actuation signal to the central control means via the telephone line;

The central control means sends a confirmation signal to the radio section of the activated fire alarm via the telephone line, nearby reporting means, and radio section.

[For production]

When the automatic alarm detects a fire, gas leak, electrical leakage, etc., the control unit sends a signal indicating the activation of the automatic alarm and a code signal indicating the installation location of the automatic alarm to the reporting means, and sends the alarm via the telephone line. and transmits it to the central processing means. These signals received from the telephone line are processed by the central processing unit of the central control means, and are converted into information such as readable characters and displayed by the display means. Therefore, when the automatic alarm detects a fire or the like, it is automatically displayed on the display means of the central control means, so that the above-mentioned delay in reporting can be eliminated.

Further, upon receiving the activation signal, the central processing section of the central control means immediately dials the installation location of the corresponding automatic alarm and transmits a confirmation signal.

On the other hand, if the notification means is inoperable and the confirmation signal cannot be received, that is, if the corresponding telephone line is defective due to a fire, etc., the control unit transmits the activation signal by the radio unit in a preset order. The activation signal and the like transmitted to the first neighboring radio unit and received by this radio unit are reported to the central processing means via the telephone line on the radio unit side. If the confirmation signal cannot be received even after transmitting to the neighboring radio unit to which it was first transmitted, the transmitter further transmits to the second location according to the set order.

The signal is transmitted to the control unit 3 via the first transmitting/receiving unit 5, and the control unit 3 operates the alarm based on the signal from the main power switch of the fire alarm 1, the alarm operation switch, and the central monitoring room. It is checked to see if the switches etc. for the transmission are set to the on state, and these check signals are transmitted again via the first transmitting/receiving section 5 and the second transmitting/receiving section 16 from the modem 6 to the second interface section 7 for telephone transmission. do. These check signals are sent to the fire department 21 through a dedicated line 9 along with a code number signal representing the installation location of the fire alarm 1.6 These received signals are processed by the CPU 23 via the interface section 22 of the fire department 21 Processing is performed so that the set status of each fire alarm 1 can be displayed on the CRT 25. The code number signal is converted to the name of each inn, and the set status of each fire alarm 1 of the inn is displayed on the cRT 25 along with the inn name. This information is also recorded by printer 26. If the fire alarm 1 is not set correctly, the CPU 23 detects the corresponding telephone number from the code number signal and automatically dials the other party. As a result, the telephone 8 of the corresponding inn rings, and when the other party picks up the handset of the telephone 21, the fire alarm 1 is set correctly using a human voice or a synthesized voice signal generated from the CPU 23 by a conventionally known method. instruct them to do so.

Therefore, it is possible to prevent an accident in which the fire alarm does not detect the occurrence of a fire because it is not set correctly to prevent malfunction or tampering, resulting in loss of human life. This automatic dialing is performed by the CPU 1 of the central control means 11.
3, the automatic dialing unit 23 may be configured to automatically dial the corresponding inn when it is determined that the setting is not correct.

Now, when a fire breaks out in the inn 11 and the fire alarm 1 detects it and activates, the control unit 3 immediately sends a fire signal different from the signal indicating the set state to the first and second transmitting/receiving units 5, 16. Then, the fire is reported to the fire station 21 via the modem 6 6 The signal is sent from the central interface section 22 to the C
The information is sent to PU 23 and displayed on the CRT 25 in which inn the fire occurred.

Emit an alarm sound. After confirming the report, the monitor operates the keyboard and sends a confirmation signal. This confirmation signal is confirmed by the control unit 3 of the inn 11. On the other hand, if a confirmation signal from the CPU 23 is not obtained even after transmitting the fire signal multiple times using the above method, for example, the modem 6 or the interface unit 7
If a fire occurs near the inn 12 and they do not function and the confirmation signal cannot be received, the control unit 3 transmits the signals in a preset order, that is, first to the second transceiver unit 16 of the inn 12;
When the confirmation signal cannot be received, it is sent to the second transmitting/receiving section 16 of the inn 13 according to the destination order.
A fire outbreak is transmitted to nearby inns 12 using weak radio waves. When the radio signal is received by the second transmitting/receiving section 16 of the inn 12, it is transmitted to the fire station 21 via the control section 3, modem 6, and second interface section 7 via the telephone office line. At this time, if a confirmation signal is not obtained even after transmitting to the inn 12, the signal is transmitted to the inn 13. The fire station 21 sends a confirmation signal in accordance with the transmitted progress, and can receive the confirmation signal from the first transmitter/receiver 5 at the fire site. In this case, each transmitter/receiver may be assigned a code number, and each transmitter/receiver may be identified by this code number.

In the above embodiment, the fire alarm 1 is activated by the first and second
Telephone notifications are made via the transmitting and receiving sections 5 and 16, but the second transmitting section 16 is omitted, the control section 3 and the modem 6 are connected, and an activation signal is first sent to the modem 6 by wire, and a confirmation signal is received. If this is not possible, the first transmitter/receiver 5 may transmit to a nearby first transmitter/receiver. Further, the operation check of each fire alarm 1 and the transmission of confirmation signals are performed by operating the keyboard 27 of the central control means 11, but the operation check is performed by storing the transmission order in the CPU 13 in advance. - It may be possible to send data sequentially with key presses,
The confirmation signal may be automatically transmitted immediately upon receiving the activation signal.

Although the above-mentioned embodiment has been explained by taking the case of fire as an example, it is of course applicable to emergency alarm equipment for gas leakage, electric leakage, etc.

〔Effect of the invention〕

As described above, the automatic alarm monitoring system of this invention is as follows.

When an automatic alarm detects a fire, gas leak, electrical leakage, etc., a signal indicating the operating status of the automatic alarm and a code signal indicating the installation location of the automatic alarm are automatically sent to a central monitoring room etc. via telephone line. The information is transmitted and is converted into information such as readable characters by the display means via the central processing unit of the central control means and displayed, and a confirmation signal is automatically transmitted by telephone to the installation location of the corresponding automatic alarm. If the telephone line at the source of the fire is unable to transmit due to a fire, etc., the wireless transmitter/receiver notifies a nearby wireless transmitter/receiver of the occurrence of the fire, and the telephone line connected to the wireless transmitter/receiver is used to report the occurrence of the fire. Therefore, when an automatic alarm detects a fire, etc., it can automatically notify the central control means by telephone, which eliminates the need for a telephone report from the source of the fire as in the past. Situations such as being unable to contact are completely preventable. Further, since the notification means has a transmission order set such that when telephone contact is impossible, a nearby telephone line is used via wireless, so that delays in initial notification can be prevented. Since the automatic alarm and the communication means are connected wirelessly or by wire, even if the wired circuit in the area where the fire is occurring becomes invalid, the nearby wired circuit can be used via wireless. , which can reliably transmit a fire signal. Furthermore, since wireless transmission and reception can be performed within a limited range, a range of 100 to 200 meters is sufficient.
A weak or minute radio wave is sufficient, and the configuration of the transmitter/receiver can be made smaller.
