Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an automatic alarm monitoring system that automatically reports the occurrence of a disaster such as a fire, gas leak, or electrical leakage to the competent fire department, central monitoring headquarters, etc. In other words, the operation of automatic alarms that automatically detect disasters should be accurately communicated to the fire department in charge and the central monitoring headquarters, and if the operating status of each automatic alarm is not set correctly, the fire department, etc. will forcefully notify the operating state of each automatic alarm. [Technical background of the invention] For example, in lodging facilities or halls that accommodate a large number of people, fire alarms are set at predetermined intervals for fire prevention and early detection. It is compulsory to install the This kind of fire alarm.

It can be monitored in the central monitoring room.
A fire alarm that detects a fire sounds an emergency bell or buzzer to alert people near the fire alarm to the occurrence of a fire, and also notifies a central monitoring room of the occurrence of a fire. The lifeguard immediately operates a telephone and dials 119 to notify the fire department of the outbreak of a fire.After confirming the status of the fire, the lifeguard immediately calls all the people inside 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. Also, in the case of a dedicated line, unlike telephone reporting, there are no mistakes in numbers, but the disadvantage is that the usage fee for the dedicated line is high. A more important problem is that automatic fire alarms may not be powered on or the alarm switch may be turned off. This is a case where the installer turns off the fire alarm in the name of preventing the fire alarm from going off due to malfunction or mischief. As a result, early detection of fires is delayed, often resulting in greater damage.

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 have a simple configuration, so that when a fire occurs, the fire alarm, etc. that detected the fire can directly notify the fire department, etc., and the fire department, etc. can confirm the set status of each alarm, etc. To provide an automatic alarm monitoring system capable of forcibly setting a fire alarm that is not set correctly.

[Means for solving problems]

The automatic alarm monitoring system of the present invention is a system in which the operating state of an automatic alarm equipped with one or more manual switches for manually turning on and off the power supply, alarm, etc. is monitored at a monitoring headquarters, and the automatic An operation switch is provided corresponding to each manual switch so that each manual switch of the alarm can be operated individually electrically, and the activation signal and this activation are detected by detecting the activation of the automatic alarm and the set state of each manual switch. A control means comprising a control unit that generates a signal indicating a set state different from the signal, and a transmitting/receiving unit that transmits each signal of the control unit using weak radio waves together with a code signal that identifies the installation location of the automatic alarm. , a transmitting/receiving means installed within the reach of weak radio waves, and a transmitting/receiving means installed at the monitoring headquarters, connected to the transmitting/receiving means by a dedicated line, converting each reported signal into readable information, and transmitting the desired automatic alarm. a central processing unit that sets and instructs to transmit a code number and an operation signal for switching each operation switch; and a display unit that displays information from the central processing unit.
Each signal from the automatic alarm is transmitted on weak radio waves to the transmitting/receiving means, which then transmits it to the monitoring headquarters via a dedicated line.
Displays the automatic alarm operation along with location information on the display,
A code signal is transmitted from the transmitting/receiving means to the transmitting/receiving section in order to confirm the desired set state of the automatic alarm set by the central processing section, and a signal indicating the desired set state of the automatic alarm is sent from the transmitting/receiving section of the control means. The alarm is sent to monitor the setting status, and if an automatic alarm is not set correctly, an operation signal is sent to force the alarm to be set.

[For production]

When the automatic alarm detects a fire, gas leak, electrical leakage, etc., the control section of the control means sends a signal indicating the operating status of the automatic alarm and a code signal indicating the installation location of the automatic alarm to the transmitter/receiver section using weak radio waves. and transmit it to the transmitting/receiving means. These signals received by the transmitting/receiving means are sent through a dedicated line to the central processing section of the central control means, where the central processing section converts them into information such as characters that can be read by the display means and displays them on 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. In addition, the central control means sends a command to the transmitter/receiver of the other party's control means via the transmitter/receiver to determine whether or not the desired automatic alarm is set correctly, and receives the result. If not, it is possible to send an operation signal to force the corresponding automatic alarm to set correctly. Since the automatic alarm and the transmitting/receiving means are connected wirelessly, many automatic alarms can be connected to one transmitting/receiving means, so even if an expensive dedicated line is used, only one
It can be used inexpensively by assigning it to an automatic alarm.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings, taking as an example a fire report in an inn district. A plurality of fire alarms 1 are installed in each inn in accordance with installation standards such as floor area. These fire alarms 1 may be conventionally well-known devices having a detection device for detecting a fire and an alarm device that emits a bell or buzzer sound in response to the operation of the detection device or an instruction signal from a central monitoring room. Explanation and drawings of the structure will be omitted. These fire alarms 1 also have, as in the past, a main power supply, a signal input for operating the alarm, and a signal input indicating the operating status to operate all the alarms in the building based on the signal from the central monitoring room. It shall be equipped with a manual operation switch. In addition, although not shown, in addition to these manual operation switches, there is also an operation switch that electrically turns on each of these manual operation switches. Even if the operation knob of the operation switch is configured to be switched to the on position, if a bypass circuit is provided for each manual operation switch, an electronic switch is provided in this bypass circuit, and this electronic switch is turned on by the operation signal. good.

A control means 2 is connected to these fire alarms 1 as shown in FIG. This control means 2 is a fire alarm 1
an interface unit 3 for importing various data from the fire alarm and controlling the operating switch of the fire alarm; It has a control section 4 that processes the code signal to be transmitted as well, and a transmitting/receiving section 6 that carries the output signal of the control section 4 on a weak radio wave and transmits it through an antenna 5. If the code signal received by the transmitter/receiver 6 corresponds to the code signal, the control unit 4 also analyzes the transmitted instruction data and performs signal processing to output a signal for controlling the power switch of the fire alarm 1, etc. . The code number signal is a combination of signals representing multiple numbers.

Wireless information from a plurality of fire alarms 1 installed in each inn and fire alarms 1 of adjacent inns is transmitted within a radius of 50, for example.
The signal is received by the transmitting/receiving section 8 via the antenna 7 provided in each area of ~100 m.

Although FIG. 1 shows two districts and two fire alarms 1 connected to each district, it should be understood that this is only for the purpose of simplifying the drawing. Each transmitting/receiving unit 8 is connected to a central control means 1 of a fire department under jurisdiction via a dedicated line 9.
Connected to 1.

As shown in FIG. 3, the central control means 11 includes an interface section 12 for taking in the received signal from the receiving section 8 as data, and a microcontroller for converting and recording the data from this interface section 12 so that it can be displayed. It has a central processing unit (hereinafter referred to as CPU) 13 made up of a computer, etc., and a storage section 14 made up of RAM and ROM for storing data from the CPU 13 and analyzing incoming data. are doing. The CPU 13 includes a CRT 15 for displaying data, a printer 16 for recording data, and reading data stored in a storage section 14.

A keyboard 17 is connected for instructing display and recording, and for instructing the code number of the desired fire alarm 1 and the operation of the operation switch. The code number instruction is set using the numeric keypad (not shown) of the keyboard 17.

First, in order to ascertain whether the set state of each fire alarm 1 within the jurisdiction is correctly set, the code number of each fire alarm 1 is sequentially indicated by operating the numeric keypad of the keyboard 17. This code number is sent to the transmitting/receiving means 8 via the CPU 13, the interface unit 12, and the dedicated line 9.
is sent to the transmitting/receiving section 6 of each control means 2 on a weak radio wave.
When the control unit 4 of each control means 2 identifies the corresponding code number, the control unit 4 transmits the manual switch for the main power of the fire alarm 1, the manual switch for operating the alarm, and the central monitoring. It is checked whether manual switches and the like for operating alarms are set to the on state using signals from the room, and these check signals are transmitted from the transmitting/receiving section 6 to the transmitting/receiving section 8 via the antenna 7. These check signals, along with a code number signal representing the installation location of the fire alarm 1, are sent through a dedicated line 9 to a central control means 11 such as the local fire department headquarters.

These received signals are processed by the CPU 13 in the interface section 12 of the central control means 11, and processed in the CPU 13 so that the set status of each fire alarm 1 can be displayed on the CRT 15. The code number signal is converted into the name of each inn, and the inn name and the set status of each fire alarm 1 of the inn are displayed on the CRT 15. This information is also recorded by the printer 16. If the fire alarm 1 is not set correctly, the supervisor of the central control means 11 will not be mistaken if the alarm is sounded or the display of the fire alarm 1 flashes. in this case,
The watchman immediately operates the keyboard 17 to forcibly turn on the manual switch that has not been set together with the code number of the corresponding fire alarm 1, and sets an operation signal to operate the operation switch corresponding to the manual switch. Then, it instructs the transmitting/receiving section 8 to transmit via the dedicated line 9.

When the transmitting/receiving section 6 of the control means 2 of the fire alarm 1 receives this operation signal, the interface section 3 turns on the corresponding operation switch via the control section 4 to forcibly set the switch. 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.

When a fire occurs and the fire alarm 1 detects it and activates, the control unit 4 immediately operates to transmit a fire signal from the transmitting unit 6 that is different from the signal indicating the set state described above, and the signal is not received. 8 to the CPU 13, and the CRTlS
The screen will display which inn the fire has broken out in and will sound an alarm, so the lifeguard will call the inn, find out about the fire situation, and call the local fire department to dispatch the appropriate fire engine. Request dispatch. If a fire breaks out near a telephone exchange and you cannot be contacted by phone, you can call the nearby inn, etc.

In the above-described embodiment, the operation of each fire alarm 1 is checked by operating the keyboard 17 of the central control means 11, but the transmission order is stored in the CPU 13 in advance, and the - number of key operations is performed. It may also be possible to send them sequentially. Furthermore, if the setting is not correct, the CPU 13 may automatically issue an operation 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, in the automatic alarm monitoring system of the present invention, when an automatic alarm detects a fire, gas leak, electric 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 sent. The signals received by the transmitting/receiving means are sent via a dedicated line to the central processing unit of the central control means installed in a central monitoring room, etc., and the signals are sent on weak radio waves to the transmitting/receiving means, and the signals are sent to the central processing unit of the central control means installed in a central monitoring room, etc. This information is converted into information and displayed. Therefore, as soon as the automatic alarm detects a fire, etc., it is automatically displayed on the display means of the central control means, so there is no need to make a telephone report as in the past, and there is no need to dial the wrong number or be unable to make a call due to incorrect operation. Such situations are completely preventable. In addition, the operating status of each automatic alarm can be checked at the desired time by the central control means, and if it is not set correctly, it can be forcibly set immediately. This eliminates drawbacks such as delays in initial discovery due to incorrect settings.

Since the automatic alarm device and the receiving means are connected wirelessly, a large number of automatic alarm devices can be connected to one receiving means, and it is extremely easy to increase/decrease or relocate them. It is also economical because the number of dedicated circuits is small. Furthermore, since wireless transmission and reception can be performed over a range of 100 to 200 m, weak or minute radio waves are sufficient, and the configuration of the transmitting and receiving section can thus be miniaturized.
