Description

[Detailed description of the invention] [Industrial application field] The present invention is applicable to general buildings, hotels, and department stores.

Concerning comprehensive disaster prevention systems applied to disaster prevention facilities such as passenger ships.

[Conventional technology]

Conventional disaster prevention facilities simply detect a fire and extinguish it using sprinklers in that area, leaving evacuation guidance to humans.Also, disaster prevention systems are designed to centrally monitor the area and situation where the disaster occurred. There is nothing to support evacuation guidance.

However, in buildings where multiple rooms are arranged horizontally and vertically in multiple layers and are interconnected by multiple corridors, two emergency exit stairs, etc., it is important to ensure that residents can evacuate safely and quickly in the event of a disaster. Therefore, it is important to establish a comprehensive disaster prevention system using a computer system to minimize damage.

Therefore, the present inventor previously published a patent application No. 6,312,9297 in which a plurality of fire detectors or flood detectors installed in buildings, ships, etc., and a system for recognizing fire and flood areas, as shown in Fig. 5, were proposed. , a disaster prevention computer system that creates an evacuation guidance route in a direction away from the disaster prevention computer system, a disaster prevention monitor display that monitors the disaster occurrence situation and the evacuation guidance route, and a disaster prevention computer system that creates an evacuation guidance route in the direction away from the disaster prevention computer system. We proposed a comprehensive disaster prevention system equipped with multiple evacuation guide lights that indicate direction.

That is, when a fire is detected by the fire detector 01, the information is input to the disaster prevention computer 03 through the interface 02.

The disaster prevention computer 03 is equipped with a storage device 04, in which data on the structure of the hotel passageway and the installation position of the evacuation direction indicator 05 is stored in coded form.
Based on these data, the disaster prevention computer 03 determines the direction away from the point where the fire occurred at the position of each indicator, and lights one of the arrows of the evacuation direction indicator 05 through the direction indicator interface 06.

In addition, a disaster prevention monitor display 07 is connected to the disaster prevention computer 03, and displays the structural diagram of the hotel shown in Fig. 6 and the location of the evacuation direction indicators 05, and displays the location of the fire outbreak and each direction indicator. Since the designated direction is centrally monitored, if it is necessary to change the direction of evacuation guidance due to the fire situation, this will be done on the disaster prevention monitor display 07.

Here, to describe the evacuation guidance guidelines for residents with reference to Figure 6, based on the installation positions of evacuation direction indicators 05a to 05q, the hotel floor is located in the disaster prevention area A on the side, as shown by the broken line.
-H, and the connections of the following four lateral direction indicators 05a to 05n starting from the emergency exits 010a to 010d, respectively, are stored as data in the data storage device 04.

(1) 010 a-=05 a→05 b-05c
→05 d-=05 e-05f-05g (21010
b-05g-=05 f →05 e-05d-”0

05 m-05n (41010d-”05 n→05 m-”051-0
5 → 05j → 05i → 05h Now, when fire detector 01 detects a fire in cabin 012 (marked with an x), the evacuation direction indicators are selected from the file in which the direction indicators on the boundary of section E are stored. 05d, 05
e.

Since 05j and 05k are recognized, the above (1) to (4)
The evacuation direction is determined based on the connected data of the direction indicators.

In the case of emergency exit 010a, indicator 05 adjacent to the fire compartment
d, the emergency exit 010a direction is determined as the MN direction,
Similarly, in the case of emergency exits 010b, 010c, and 010d, the directions up to the indicators 05d, 05e, and 05j are determined as the evacuation direction.

Vertical indicators 05o, 05p, and 05q are similarly divided into vertical disaster prevention divisions, R, and one of the direction indicators used in (1) to (4) above is assumed to be an emergency exit ( 1)～(
Similarly to 4), store the connection data and use the indicators 05d and 05e.

There is no need to memorize the connections from exits 010a to 010d for 05j and 05 (doing so may cause problems).For example, for indicator 050, (1)' 05 b-"05 o-05m(2)'
05m-"05o-+05b (virtually the exit), the direction away from the fire source cabin 012 is determined as the evacuation direction.

By the above method, the emergency staircase 011a.

A safe evacuation route leading to 011b can be synthesized and shown to evacuees.

However, in this type of disaster prevention system, the conventional fire detector 01 is typically a heat-sensitive type or an ion (smoke-sensitive) type, but both are extremely sensitive to heat and smoke and are suitable for early detection of fire. However, when a fire spreads, there is a high possibility that even detectors in areas where the fire has not spread will be activated, so it is difficult to accurately detect areas where the fire has spread, especially when used as basic data for calculating and instructing evacuation routes. In order to correctly understand the fire spread areas and non-fire spread areas,
Not suitable.

Further, since a part of the signal line network itself is burnt out due to the fire source and its fire spread area, there is a risk that it may not be possible to accurately determine the burnt area and the area where the fire has not spread.

[Problem to be solved by the invention]

The present invention was proposed in view of the above circumstances, and utilizes a loopback function that is activated when a part of a loop local area network (hereinafter referred to as LAN) is damaged to locate the location of a fire and the area where the fire has spread. The purpose is to provide a highly reliable comprehensive disaster prevention system that automatically detects disasters.

[Means to solve the problem]

To this end, the present invention provides a disaster prevention system that uses a plurality of fire detectors or flood detectors that are connected to electrical cable networks installed in buildings, ships, etc., and that recognizes fire or flooded areas and creates evacuation guidance routes in the direction away from them. a computer system, a disaster prevention monitor display for monitoring the disaster occurrence situation and evacuation guidance route, and a plurality of evacuation guidance indicator lights that indicate the direction in which to go along the evacuation guidance route created by the disaster prevention computer system. A comprehensive disaster prevention system comprising: The above network is implemented as a loop-type local area network with a loopback function, and each node is equipped with a fire detector, a disaster prevention monitor display, and a master station run. shall be.

[Effect]

According to such a disaster prevention system, when a disaster occurs, it detects the area where the disaster occurred, compares the route data stored in the computer with the installation data of the evacuation direction indicators, and determines the WN direction at each indicator setting position. The results can be calculated and displayed with arrows on each indicator.

Even if a part of the network is damaged due to the spread of a fire, the damaged network part will be automatically disconnected, and only the remaining healthy network part will automatically detect the area where the fire has spread and display the evacuation direction on each indicator. do.

〔Example〕

An embodiment in which the present invention is applied to a hotel will be explained with reference to the drawings. Fig. 1 is a plan view thereof, Fig. 2 is a partially enlarged view of Fig. 1, and Fig. 3 is a loop caused by burnout of the loop in Fig. 2. FIG. 4 is a flowchart showing the relationship between the operation of the fire detector in FIG. 1 and the loop back action.

First, in FIG. 1, reference numeral 3 denotes a loop-type local area network 4-a installed in a building 2 divided into 15 sections 1 marked A to ○.

4-b is the boundary of each section. A node 5 of the LAN 3 is installed in each compartment, and a fire detector 6 is connected to each node 5, as well as information devices such as a display 7. The LAN 3 provides information on fire detection, data services, etc. Acts as a data transmission medium.

On the other hand, a master station 8 for managing and controlling data transmission of the LAN 3 and a comprehensive disaster prevention system 9 connected thereto are installed in the central monitoring room 1-a. Loop type L
AN is common because it is designed to have duplicate cables and to operate a loopback function so that data transmission will not be hindered even if a disconnection occurs.

Next, in Fig. 2, the LAN3 cable has a two-core structure with an active system 3-a and a standby system 3-b, and normally the active system 3-a forms a loop as a data transmission path. , standby system 3
-b is not performing well.

When a part 10 of this cable is disconnected, the adjacent nodes 5-a and 5-b are connected to the active system 3-a and the standby system 3-a.
By automatically short-circuiting the active system 3-a and the standby system 3-b, both the active system 3-a and the standby system 3-b form a loop and maintain their function as data transmission paths.

In this case, the master station 8 or the processing device (comprehensive disaster prevention system) 9 connected thereto has a function of detecting the nodes 5a and 5-b that are turning back in the manner described later. The above is the loopback function of a general loop type LAN.

Now, when the fire detector 6 in section H detects the occurrence of a fire, the information is sent to the comprehensive disaster prevention system 9 through the operation system 3-a.
transmitted to. As the fire progresses, part of the cable 10
When a burnout occurs as shown by the mark, the integrated disaster prevention system recognizes the return nodes 5-a and 5-b using the loopback function, and is able to confirm that the fire has spread during this time.

Therefore, as shown in FIG. 3, when the fire spreads to both compartments H1■, the comprehensive disaster prevention system 9 detects return nodes 5-b and 5-d.

On the other hand, the comprehensive disaster prevention system 9 retains the structure of the building and the arrangement of nodes as data in its storage device, and verifies the above-mentioned turnaround nodes to ensure the fire spread area in the same manner as described with respect to Figures 5 and 6. In addition to understanding the
Residents can be guided to evacuate, and by subdividing the sections, it is possible to understand the fire spread area in more detail.

This information is extremely important for initial firefighting activities and evacuation guidance.

As mentioned above, conventional fire detectors detect heat.

It is very sensitive to smoke, so it is useful for early detection of fires, but when a fire spreads, fire detectors in areas where the fire has not spread will also be activated, so it is not suitable as a sensor for detecting areas where fire has spread. Therefore, in the present invention, the fire detector is used as a sensor for the fire compartment, and in order to obtain basic data for calculation of the evacuation taxiway, a loopback function to ensure reliable burnout is installed in the fire spread compartment. It is used as a sensor.

As described above, since the fire detector and the Louvva Nok function have completely different information properties, their operation and maintenance are performed according to the flowchart shown in FIG.

〔Effect of the invention〕

According to such a system, the following effects can be achieved.

(1) Since the loop-type local area network, which is popular in recent intelligent buildings, is used as is, it is highly reliable and low cost.

(2) In the event of a disaster such as a fire or flooding in a building such as a hotel, department store, hospital or passenger ship, it is possible to quickly and accurately locate an evacuation route to an emergency exit.

(3) By displaying the evacuation route with an arrow on the evacuation direction indicator placed inside the building, evacuees can be guided to the emergency exit without unnecessary confusion.

(4) This method can also be applied to opening/closing guidance/automation of emergency doors.

In short, according to the present invention, a plurality of fire detectors or flood detectors each connected to a wire network installed in a building, ship, etc., recognize a fire or a flooded area, and create an evacuation guidance route in a direction away from the fire or flooded area. A disaster prevention computer system, a disaster prevention monitor display for monitoring the disaster occurrence situation and the M-difficult guidance route, and a plurality of evacuation guidance indicator lights that indicate the direction to evacuate along the evacuation guidance route created by the disaster prevention computer system. In the comprehensive disaster prevention system, the above network is formed as a loop-type low-power area network with a loopback function, and each node is equipped with a fire detector, a disaster prevention monitor display, and a master station. This caused the fire to occur.

The present invention is extremely useful industrially because it provides a reliable, low-cost comprehensive disaster prevention system that automatically detects areas where fire has spread.
