Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster prevention monitoring device for monitoring both a fire and a crime by installing a security detector together with a fire detector in a guard area.

[0002]

2. Description of the Related Art Conventionally, most security monitoring devices using a security detector have been installed and operated independently, but in recent years, they have been combined with an entrance / exit management system for buildings and the like, and have left the company. In conjunction with the locking at the time, a security detector is set to monitor theft. In recent years, fires,
In order to collectively manage security such as theft and abnormalities,
A comprehensive disaster prevention monitoring device combining fire monitoring and theft monitoring is being considered.

Further, there is a fire alarm system disclosed in Japanese Patent Application Laid-Open No. Hei 6-274768, for example, which detects and uses the presence or absence of a person for fire judgment. This fire alarm system
When the fire detector issues an alarm, the actual fire is determined by referring to the determination signal from the human body presence / absence detection system. That is, since a false alarm of a fire detector is likely to occur in a state where a person is present in cigarette smoke or the like in a conference or the like in which a large number of people have participated, when a fire detector emits a warning, a human body presence detection system is used. The presence / absence information of a person, which is discriminated and output, is used, and if a person is present, it is regarded as an erroneous report and the real fire is not immediately reported.

[0004]

However, it is not always appropriate to judge whether a real fire or a false alarm is made based on whether or not a person exists in a guard area, and a real fire occurs even when there is no person. And false alarms of fire detectors also occur. In the case of connecting a fire alarm and a security detector to the receiver of the fire alarm device for combined monitoring, fire monitoring is 24 hours, but security monitoring is limited to unmanned hours other than working hours such as nighttime. Become. For this reason, even if a fire detector and a security detector are connected to the same transmission line, fire monitoring and theft monitoring are performed separately, and the mutual use of information has not been sufficiently performed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a disaster prevention monitoring device in which a detection function of a security detector connected to a receiver together with a fire detector is used for evacuation guidance in a fire.

[0006]

In order to achieve this object, the present invention is configured as follows. First, according to the present invention, a plurality of fire detectors are connected to a transmission path from a receiver, detection data is returned from the fire detectors by successive calls from the receiver, and a fire is determined by the receiver based on the detection data. For disaster prevention monitoring devices.

The present invention relates to such a disaster prevention monitoring device,
In addition to the fire detector, a security detector that detects and outputs the presence of a person in the section for each predetermined warning area is installed. When the fire processing unit determines a fire and a fire occurrence section based on the detection data from the fire detector, the security processing unit
The security detector installed in the fire occurrence section is set to the operating state, and it is determined whether or not there is a person in the fire occurrence section.

Further, the security processing section sets the security detector installed in a section adjacent to the fire occurrence section in addition to the fire occurrence section to an operating state, and determines whether or not a person is present. The security processing unit, when judging the presence of a person, causes evacuation guidance by emergency broadcast, display drive, or the like. In the regular monitoring state, the security processing unit sets the security detector to the operating state for a predetermined time period in which the security area is not used, and performs a security alarm process when a detection output is obtained from the security detector.

According to the disaster prevention monitoring device of the present invention, when a fire is determined, the security detectors installed in the fire occurrence section and the adjacent section are automatically set to the operation state, and the security detector is set. Then, it is determined whether or not there is a person in the fire occurrence section and / or the adjacent section. At this time, if a person is present, an appropriate evacuation route and direction can be indicated by an emergency broadcast, an evacuation route guide light, or the like, and evacuation can be quickly performed to a safe place.

[0010]

FIG. 1 is a block diagram of an embodiment of a disaster prevention monitoring device according to the present invention. In FIG. 1, for example, transmission lines 2-1 and 2-2 are pulled out from the disaster prevention receiver 1 toward the guard area, and in this embodiment, the transmission line 2-1 is used.
A fire monitoring detector is connected to the transmission line 2-2, and a security monitoring detector is connected to the transmission line 2-2.

That is, the transmission line 2- provided for fire monitoring
Reference numeral 1 denotes a repeater 3 connected to an on / off type fire detector 4 via a sensor line, an analog smoke sensor 5 having a repeater function, an analog heat sensor 6 having a repeater function, and a repeater. A transmitter 7 having a function is connected. On the other hand, on the side of the security transmission line 2-2, a repeater 8 connected to on-off type security detectors 8a, 8b, 8c via a signal line;
Security detector 9 with repeater function, transmitter 11 and receiver 1
2 is connected to a separation-type security detector 10 in which components 2 are separately arranged.

The disaster prevention receiver 1 includes a terminal transmission unit 13 and a microprocessor (hereinafter, “MPU”) functioning as a control unit.
14) are provided. The MPU 14 includes a fire processing unit 15 and a security processing unit 1 realized by program control.
Six functions are provided. The terminal transmission unit 13 of the disaster prevention receiver 1 repeats a terminal call specifying a predetermined terminal address for each of the transmission lines 2-1 and 2-2 at a constant cycle, and fire and crime prevention for the terminal call are performed. When each of the detectors receives a call corresponding to its own assigned address, it returns detection data indicating the detection state at that time. As the address of the terminal device connected to the transmission paths 2-1 and 2-2, for example, 127 addresses can be used.

Further, an emergency broadcast device 18 is provided for the disaster prevention receiver 1, and a speaker 20 is connected to an audio line 19 drawn from the emergency broadcast device 18. The emergency broadcast device 18 outputs a voice message for a fire alarm and a voice message for evacuation guidance from a speaker 20 installed in a guard area based on the processing results of the fire processing unit 15 and the crime prevention processing unit 16 in the disaster prevention receiver 1. I do.

The fire processing unit 15 provided in the disaster prevention receiver 1
The detection data obtained by sequentially calling the various fire detectors provided on the transmission line 2-1 by the terminal transmission unit 13 is compared with a predetermined fire level, and when the detection data reaches the fire level. Judgment is made of a fire, and an alarm device (not shown), sound of a district bell, and the like, and a fire alarm process using a display device are performed.

Further, the fire processing unit 15 activates the crime prevention processing unit 16 when judging a fire, and forcibly performs the crime prevention processing in the guard area where the fire has occurred. That is, the security processing unit 1
6 receives the fire judgment output and the fire occurrence section information from the fire processing section 15 and activates the security detectors installed in the fire occurrence section and the section adjacent thereto via the terminal transmission section 13 in the operating state. Is sent out.

For example, by transmitting a set command designating the address of the security detector 9 installed in the fire occurrence area, the security detector 9 is set to an operating state, and a security monitoring state is created. The security detector 9 which has been activated by the control by the set command from the security processing unit 16 detects the presence of a person if the person remains at the place and issues an alert. Is sent back to the disaster prevention receiver 1 as alert information to the user.

For this reason, the security processing section 16 can recognize in real time whether or not there is a person in the fire occurrence section and the section adjacent thereto in accordance with the information at that time. If the security processing unit 16 recognizes the presence of a person in the fire occurrence section and the adjacent section, the disaster prevention receiver 1
At the same time, a warning message indicating the presence of a person is issued by a voice message, and at the same time, a transfer signal is output to the emergency broadcast device 18, and the speaker 20 installed in the warning area is used to leave the person in the fire occurrence section and the adjacent section. Emergency broadcasts to guide evacuation to a safe place.

On the other hand, the security processing unit 1 provided in the disaster prevention receiver 1
In the normal monitoring state, security monitoring 6 is performed according to a preset time schedule. For example, in an office building or the like, in conjunction with the locking of the room key at the time of exit, the security detector in the corresponding section is controlled to be set and monitored, and when a theft alarm is received in this monitoring state,
Performs burglar alarm processing such as alarm display and external notification.

This crime prevention monitoring state is reset in conjunction with the unlocking of the room upon going to work. As described above, the setting and resetting of the security detector by the security processing unit 16 in the regular monitoring state are performed in conjunction with entering and leaving, so that when the fire is determined, the security detector is reset and placed in the non-operation state. Therefore, in response to the fire judgment output from the fire processing unit 15, the security detector is forcibly set and brought into the operating state.

FIG. 2 shows a specific example of the guard area to which the embodiment of FIG. 1 is applied, and shows a certain floor of an office building, for example. This security zone is divided into eight rooms A to G, and each room A to G has an analog smoke detector 5
a to 5g and security detectors 9a to 9g are installed, and an emergency broadcast speaker 20 is also installed. For example, if a fire F occurs in the room B in such a caution area, the room B is determined as a fire occurrence section by the detection data from the analog smoke detector 5. For this reason, in the disaster prevention receiver 1, the crime prevention detector 9b installed in the room B determined as the fire occurrence section by the crime prevention processing unit 16 is set.

Further, the security detectors 9a and 9c are similarly applied to the rooms A and C adjacent to the room B in which the fire has occurred.
Is set. In this case, since the door of the room G is the same as that of the room B which is the fire occurrence section, the security detector 9g of the room G is also set. Each of the security detectors 9a, 9b and 9c is set in each of the room B in which such a fire has occurred and the adjacent rooms A and C so as to be in an operating state. Output an alarm message indicating the presence of a person.
Therefore, the emergency broadcast device 18 is activated by the notification output to the emergency broadcast device 18 provided adjacent to the disaster prevention receiver 1, and the administrator of the disaster prevention receiver 1 sends the security detectors 9 a to 9.
An emergency broadcast for evacuation guidance is performed based on the detection result of the person by 9cg, and this is output from the speakers 20 in the rooms A to C and G.

At this time, since the presence status of the person in the fire occurrence section and the section adjacent thereto can be accurately grasped on the disaster prevention receiver 1 side, an emergency broadcast indicating an appropriate evacuation direction can be made finely. For example, a person in rooms A and B is instructed to evacuate to the left emergency stairs, and a person in room C is instructed to evacuate to the right emergency stairs. Further, as for the remaining rooms D to G on the same floor, the security detector 9
By setting d to 9G and setting the operation state, the situation of the presence of a person can be understood. Perform guidance.

Further, in the disaster prevention receiver 1, a layout diagram of a fire occurrence floor as shown in FIG. 2 is displayed on a display, and a fire occurrence area and an adjacent area considered to be dangerous are color-coded and displayed on the display. By displaying the presence or absence of a person based on the detection results of 9a to 9g, very fine evacuation guidance can be quickly and appropriately performed.

FIG. 3 shows an MPU provided in the disaster prevention receiver 1 of FIG.
14 is a flowchart of a fire and crime prevention process by No. 14.
First, in step S1, various initial settings are performed at the time of startup upon power-on, and the apparatus enters a monitoring state. In the normal monitoring state, it is checked whether the recovery switch has been turned on in step S2. Since the recovery switch is normally off, the process proceeds to step S3 to determine whether or not a fire has occurred.

When a fire is determined in step S3, a fire alarm process is performed in step S4, and in step S5, the security detectors in the fire occurrence section and the immediately adjacent section are set to the operating state. After setting the security detector, it is checked whether or not the presence of a person is detected in step S6. If the presence of a person is detected, the presence of the person is displayed by outputting or displaying a voice message in step S7. Then, an evacuation guidance broadcast is performed in step S8.

On the other hand, in the steady monitoring state, the process proceeds from step S3 to step S9 to check whether or not the security setting state has been set after leaving. If it is in the security setting state, the process proceeds to step S10, and the presence or absence of a security alert is checked. If there is a security alarm, the process proceeds to step S11, and a security alarm process is performed. In the embodiment of FIG. 1, the detectors are connected by dividing transmission lines for fire alarm and crime prevention.
A detector for fire alarm and a detector for crime prevention may be provided in the same transmission line. Further, it is desirable that the voice line 19 from the emergency broadcast device 18 be divided into a plurality of systems depending on the situation of the guard area so that more detailed evacuation guidance can be broadcast.

The security detector used in the present invention is not limited to a so-called spot security detector which detects infrared rays emitted from a human body, and a beam type security detector which detects a person by blocking a light beam. In addition, an appropriate security detector can be used.

[0028]

As described above, according to the present invention, when a fire is determined, the security detectors installed in the fire occurrence section and the adjacent section are automatically set to the operation state, It is possible to immediately judge whether or not there is a person in the fire occurrence section and / or the adjacent section by the alarm of the security detector, and if there is a person, appropriate evacuation by emergency broadcast or evacuation route guide light etc. The route and direction can be indicated, and evacuation to a safe place can be performed quickly.
