Description

[Detailed Description of the Invention] [Field of Industrial Application] The present 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. Specifically, we will accurately communicate the activation of automatic alarms that automatically detect disasters to the fire department in charge and the central monitoring headquarters, and if the fire department confirms activation, we will immediately inform them of the installation location of the automatic alarm and respond. This invention relates to an automatic alarm monitoring system that enables wireless communication.

[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 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 0, you cannot communicate with the outside world, and if you forget this point, you will not be able to get through to the phone, causing a delay in your first report. 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.

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 this invention is to use a simple configuration to enable direct notification to the fire department, etc. from the fire alarm, etc. that detected the fire in the event of a fire, etc., and to confirm the operation of each alarm, etc. at the fire department, etc. The purpose of the present invention is to provide an automatic alarm monitoring system that can immediately communicate wirelessly with the installation location.

[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 generates an activation signal, and transmits the activation signal of the control unit to a weak radio wave along with a code signal that identifies the installation location of the automatic alarm. A control means equipped with a transmitting/receiving unit that transmits and receives audio signals, a transmitting/receiving unit provided within the range of weak radio waves, and a transmitting/receiving unit provided at the monitoring headquarters and connected to the transmitting/receiving unit by a dedicated line. a central processing unit that converts the reported activation signal into readable information; a display unit that displays information from the central processing unit;
A central control means equipped with a transmitter and receiver for transmitting and receiving audio signals is provided, and the activation signal of the automatic alarm is transmitted on weak radio waves to the transmitting and receiving means, and the transmitting and receiving means transmits it to the monitoring headquarters via a dedicated line, The system displays the activation of the automatic alarm along with location information, and communicates with the corresponding control means by radio.

[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 activation of the automatic alarm and a code signal indicating the installation location of the automatic alarm to weak radio waves from the transmitter/receiver section. 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.

Moreover, since the central control means can immediately communicate by radio with the location where the corresponding automatic alarm is installed upon receiving the activation signal, it is possible to omit the need for the corresponding automatic alarm to call 119 by telephone.

Since the automatic alarm and the transmitting/receiving means are connected wirelessly, many automatic alarms can be connected to one transmitting/receiving means. It can be used inexpensively by allocating it to

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings, taking as an example a fire report at an inn. 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 switch.

A control means 2 is connected to these fire alarms 1 as shown in FIG. This control means 2 is a fire alarm 1
Interface section 3 for importing various data from
and a control unit 4 which processes various data from the fire alarm 1 so that it can be transmitted, and also processes a code signal representing the installation location information of the fire alarm 1. It is connected to a transmitting/receiving section 6 that carries the output signal of the control section 4 on a weak radio wave and transmits it from an antenna 5, and to the control section 4.

It has a handset 21 in which a transmitter and a receiver are integrally formed for transmitting and receiving voice. If the code signal received by the transmitter/receiver 6 also applies to the control unit 4,
The transmitted instruction data is analyzed and signal processed to output a signal for controlling the power switch of the fire alarm 1, etc. A code signal is a combination of signals representing multiple numbers. As shown in FIG. 1, the handset 21 is held in a plug-in manner on the side of the case of the control means 2, but it goes without saying that it may be installed at a position separate from the control means 2.

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 unit 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 section 8 is connected to a central control means 11 such as a competent fire department headquarters through a dedicated line 9.

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. A central processing unit (hereinafter referred to as CPU) 13 made up of a computer or the like, a storage unit 14 made up of RAM and ROM for storing data from the CPU 13 and analyzing incoming data, and an interface. It has a speaker 22 and a microphone 23 which are connected to the unit 12 and transmit and receive audio. The CPU 13 includes a CRT 15 for displaying data, a printer 16 for recording data, and a function for calling up data stored in the storage section 14, instructing display or recording, and instructing the code number of a desired fire alarm 1. , and a keyboard 17 for setting instructions for contacting the other party by voice if the set state is incorrect.

Instructions for the code number can be found on the numeric keypad on keyboard 17 (
(not shown).

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 code from the main power switch of the fire alarm 1, the operation switch of the alarm, and the central monitoring room. The check signals are used to check whether the switches for operating the alarm are set to the on state, 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.

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 alarm will sound or the display of the fire alarm 1 will blink, so that the observer of the central control means 11 will not make a false alarm. . In this case, the watchman immediately operates the keyboard 17 to transmit the code signal of the fire alarm 1 as an alarm signal. At the same time, the connection state with the fire alarm 1 is switched to the calling side. This switching may be done manually or automatically under the control of the central control means 11. By receiving this call signal at the transmitting/receiving section 6, voice communication can be made with the watchman by placing the handset 21 to the ear, and the watchman instructs the fire alarm 1 to be set correctly. 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 it is determined that this call signal is not set correctly by the CPU 13 of the central control means 11,
The CPU 13 may be configured to automatically transmit the code number signal of the fire alarm 1 concerned.

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 CRT 15
It displays the location of the fire at the inn above and emits an alarm sound.

Therefore, the lifeguard sends a call signal to the inn, learns about the fire situation by radio, and requests the fire department to dispatch an appropriate fire engine. If a fire occurs near the transmitter/receiver unit 6 or the handset 21 and cannot be contacted by telephone, a call may be made to a nearby inn or the like.

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. In addition, although each fire alarm 1 is set to notify only when it is not set correctly, when it is set correctly, a confirmation signal indicating that fact may be sent in a different form of the call signal 4. .

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., it sends a signal indicating the operating status of the automatic alarm and a code signal indicating the installation location of the automatic alarm. 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 can be converted and displayed, and wireless communication can be made with the corresponding automatic alarm. 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. 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. Additionally, wireless transmission and reception range is 100-200m.
, so weak or minute radio waves are sufficient.
This allows the configuration of the transmitter/receiver to be miniaturized.
