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, the activation of automatic alarms that automatically detect disasters must be accurately communicated to the local fire department and central monitoring headquarters, and when the fire department confirms activation, a loudspeaker broadcast must be made to the area where the disaster has occurred. This invention relates to an automatic alarm monitoring system that enables

[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 picks up the phone and dials 119 to notify the fire department of the outbreak of the fire.After confirming the status of the fire, the lifeguard immediately calls the entire building to evacuate, depending on the situation. Activate all fire alarms 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.

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 when a fire occurs, and when the operation of each alarm, etc. is confirmed at the fire department, etc. The object of the present invention is to provide an automatic alarm monitoring system that can immediately broadcast evacuation announcements to the area where the fire has occurred.

[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 an individual transmitting/receiving section for transmitting data, a transmitting/receiving section provided within the reach of weak radio waves, a speaker for loudspeaker broadcasting, and a control section for switching between the transmitting/receiving section and the speaker. a transmitting/receiving means, a central processing section provided in the monitoring headquarters, connected to the transmitting/receiving means via a dedicated line and converting the received activation signal into readable information, and a display section displaying information from the central processing section. , a central control means equipped with a transmitter for transmitting audio signals or a recorder for recording messages such as evacuation, etc., and transmits the activation signal of the automatic alarm on weak radio waves to the transmitting/receiving means. is transmitted to the monitoring headquarters via a dedicated line, the operation of the automatic alarm is displayed on the display along with location information, and the alarm is audibly broadcast from the speaker of the transmitting/receiving means to which the individual transmitting/receiving section of the automatic alarm that received the report belongs. be.

[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 to the central processing section of the central control means via a dedicated line, and 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. When the device detects a fire or the like, it is automatically displayed on the display means of the central control means, so the above-mentioned delay in reporting can be eliminated.

In addition, when the central control means receives the activation signal, it checks the situation and, if necessary, broadcasts the occurrence of a fire or evacuation guidance to the relevant area.

Unlike broadcasting from the source of a fire, which is in a state of confusion, it is possible to broadcast accurately. 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 that processes various data from the fire alarm 1 so that it can be transmitted, and also processes a code (No. 3) representing the installation location information of the fire alarm 1. It has a transmitting/receiving section 6 that transmits the output signal on a weak radio wave from the antenna 5.The control section 4 also transmits the transmitted instruction data when the code signal received by the transmitting/receiving section 6 corresponds to the code signal. The code signal is analyzed and processed to output a signal that controls the power switch of the fire alarm 1, etc. The code signal is a combination of signals representing a plurality of numbers.

Wireless information from multiple fire alarms 1 installed in each inn and fire alarms 1 of adjacent inns.

For example, the signal is received by the transmitting/receiving means 8 via the antenna 7 provided in each district with a radius of 50" and 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 means 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 microphone 18 that is connected to the section 12 and transmits audio. The CPU 13 includes a CRT 15 for displaying data, a printer 16 for recording data, and a memory unit 14 for recalling data stored in the storage unit 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. The code number instruction is set using the numeric keypad (not shown) of the keyboard 17.

The transmitting/receiving means 8 has a control section 21 connected to an interface section 12 of the central control means 11 through a dedicated line 9.

An amplifier 22 connected to the control section 21 to amplify the audio signal from the microphone 18, an outdoor speaker 23 for broadcasting the output of the amplifier 22, and a transmitting/receiving section communicating with the transmitting/receiving section 6 of the control means 2 using weak radio waves. 24. The control section 21 identifies whether the transmission signal from the central control means 11 is a broadcast signal or is for calling up one individual control means, and automatically switches to the amplifier 22 or the transmitting/receiving section 24 side.

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 disaster 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 calls the inn where the fire alarm 1 is installed and instructs it to set it 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 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
It displays the location of the fire at the inn above and emits an alarm sound.

Therefore, the lifeguard calls the inn, inquires about the situation of the fire, and requests the fire department to dispatch the appropriate fire engine. If a fire breaks out near a telephone and you cannot be contacted by phone, you can call the nearby inn, etc.

On the other hand, judging from the fire situation, if necessary, the lifeguard operates the keyboard 17 to send an instruction signal to activate the amplifier 22 to the transmitting/receiving means 8 belonging to the inn that reported the fire via the dedicated line 9. and transmit it. This instruction signal is confirmed by the control unit 21 and the amplifier 22 is activated. The watchman uses the microphone 18 to broadcast which inn a fire has occurred in and provides evacuation guidance.When a fire occurs at the boundary between each transmitting/receiving means 8, a broadcast is made from the speakers 23 of two or more transmitting/receiving means 8. If the CPU 13 sets in advance which speaker 23 should be used to broadcast depending on the location of the fire, there is no need for the lifeguard to select and set which speaker to broadcast from.) .

In the above-mentioned embodiment, the broadcast is made using the microphone 18, but instead of using a recorder in which messages such as evacuation are recorded in advance, the recorder may be operated as needed. In addition, 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 transmission is performed sequentially by - number of key operations. You may also do so.

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 telephone contact can be made with the location where the corresponding automatic alarm has been installed. Therefore, as soon as the automatic alarm detects a fire etc., it is automatically displayed on the display means of the central control means.

This eliminates the need for telephone calls from the source of the fire, as was the case in the past, and completely prevents situations where calls are not possible due to dialing the wrong number or incorrect operation. Moreover, since the occurrence of a fire is broadcast audibly from the loudspeaker of the transmitting/receiving means at the monitoring headquarters, it is possible to accurately inform the area and prevent unnecessary confusion. 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 meters, weak or minute radio waves are sufficient.

This allows the configuration of the transmitter/receiver to be miniaturized.
