Abstract

[Problem] To enable quick water discharge operations by making the water discharge operation display device, which is located inside a control box with the door closed and is normally not displayed, usable when the door is opened. [Solution] The on-site control console 30, which operates the water cannon system that discharges firefighting water, is housed in an operation box 46 equipped with an openable and closable door 50 and has a liquid crystal display device that allows the water cannon system to be operated by touch operation on the screen. The standby control unit switches the display device, which is normally in a non-display state when the door of the operation box 46 is closed, to an operable display state when predetermined conditions for starting use of the on-site control console are met, for example, when a fire detection signal for the protected area is received from the central control panel, and puts it into standby mode. When the door 50 of the operation box 46 is opened, the display device is in the display state, enabling rapid water discharge operation. [Selection Diagram] Figure 3

Description

This invention relates to a fire extinguishing system that suppresses and extinguishes a fire by discharging fire-fighting water from a water discharge unit when a fire occurs in a protected area. Traditionally, facilities (buildings) with large spaces such as sports fields and exhibition halls, as well as facilities (buildings) with high ceilings such as shops and warehouses, have been legally required to install sprinkler systems (water-type fire extinguishing systems) equipped with water-discharge heads. Legally, these systems are classified into those using movable heads and those using fixed heads. Among these, a representative example of a water-type fire extinguishing system using a movable head is a system combining a scanning fire detector and a water cannon device (movable head) (Patent Document 1). A water-based fire extinguishing system using a water cannon system consists of a water cannon system that discharges fire-extinguishing water to the protected area (the area to be extinguished) within the facility, a local control unit that controls the operation of the water cannon system (such as water discharge and horizontal scanning), and a local operation unit that performs operations to instruct the operation of the local control unit. Furthermore, a central control unit that manages and monitors all local control units and a central operation unit that allows for the selective operation of all water cannons are installed in a disaster prevention center or other location away from the protected area. In the event of a fire within the protected area, the location of the fire source (fire origin) is identified based on information from the scanning fire detector. Firefighting operations are then initiated by automatic control from the central control unit, or by manual operation from the on-site or central control unit, by discharging firefighting water from the corresponding water discharge unit towards the fire source. Here, the water discharge system can be operated from both the on-site control unit and the central control unit. However, in the event of a fire, firefighting activities are primarily conducted on-site (within the protected area) after the fire has been confirmed. Therefore, the on-site control unit is used more frequently than the central control unit during a fire. Furthermore, the on-site and central control units are not limited to use during fires; they can also display management information such as system failure information, and are therefore frequently used during inspections and adjustments during the installation of fire extinguishing equipment. The on-site control unit, being primarily used in emergencies, is housed in a control box with a door. To access the on-site control unit, operators must unlock the door with a key, preventing easy access. Furthermore, the on-site control unit is equipped with switches for activation and recovery, as well as switches for operation rights and display tests. It also includes indicator lights that show the status of fire extinguishing equipment and compartments, such as fire signals, faults like broken wires, and countdown timers until activation. Some units also have a communication port for connecting to the central control unit. In recent years, the amount of information required for displaying and operating information, such as details of malfunctions, initial settings of control units, and operation guidance, has increased. Therefore, there is a demand for on-site control units equipped with display devices that enable screen operation by incorporating a capacitive touch panel on an LCD panel. Furthermore, such fire extinguishing equipment is not used on a regular basis; it is only used in emergencies when a fire occurs. To ensure that it does not become inoperable in the event of an emergency, the Fire Service Act mandates inspections twice a year. However, since the operation of the fire extinguishing equipment during inspections is performed by personnel from the inspection company, it is highly likely that the building users, managers, and other operators who will use the equipment in an emergency have never seen or touched it.
