Description

This disclosure relates to fire prevention equipment installed in fire monitoring areas, and a fire prevention equipment locator system used to locate the installation locations of such equipment. There are fire alarm systems that consist of various fire prevention devices such as fire alarm receivers, transmitters, repeaters, sound devices, fire detectors, and controlled equipment, and protect people inside buildings and other structures that are subject to fire protection (see, for example, Patent Document 1 and Non-Patent Document 1). In a fire alarm system, fire detectors transmit a fire signal to a fire alarm receiver when they detect heat or smoke. Upon receiving the fire signal, the fire alarm receiver issues an alarm and sounds an audible device, depending on the location of the fire, to inform people within the designated area of the fire. Furthermore, a fire alarm receiver, upon receiving a fire signal, works in conjunction with the detection results of multiple fire detectors to control the operation of multiple controlled devices that function to prevent the spread of fire, smoke, etc., or to encourage evacuation. Examples of these controlled devices include fire doors, fire dampers, and bells. Japanese Patent Publication No. 2004-303009 Nohmi Disaster Prevention Co., Ltd. Homepage, Automatic Fire Alarm System (URL: https://www.nohmi.co.jp/product/materiel/fid.html) This is a functional block diagram of the disaster prevention equipment according to Embodiment 1 of the present disclosure.This is a functional block diagram of the disaster prevention equipment search system according to Embodiment 1 of the present disclosure.This is an explanatory diagram illustrating a method for identifying the installation location of a fire detector installed at a high place using the disaster prevention equipment search system according to Embodiment 1 of this disclosure. Hereinafter, preferred embodiments of the disaster prevention equipment and disaster prevention equipment search system of this disclosure will be described with reference to the drawings. The disaster prevention equipment and disaster prevention equipment search system disclosed herein are characterized by the inclusion of a light display structure in the disaster prevention equipment that emits light when power is received wirelessly transmitted. This technical feature makes it possible to easily locate the disaster prevention equipment even in various installation environments, such as cultural heritage buildings, tunnels, high ceilings, and at night. Embodiment 1. Figure 1 is a functional block diagram of a disaster prevention device according to Embodiment 1 of the present disclosure. The disaster prevention device 1 according to Embodiment 1 shown in Figure 1 is configured to include an optical display structure 10. The disaster prevention device 1 in the present disclosure includes various devices such as fire detectors, sprinklers, sound devices, and cameras installed in a fire monitoring area. The light display structure 10 is a structure that realizes the function of emitting light by receiving power wirelessly transmitted from an external source. In the following explanation, "power transmitted wirelessly" will be referred to as "wireless power." The optical display structure 10 can be configured as a structure that emits light spontaneously based on the voltage generated by receiving wireless power. In this case, the optical display structure 10 can be attached to the housing of disaster prevention equipment. Furthermore, the optical display structure 10 can also be composed of a "power receiver," a "control unit," and an "indicator light," as described later using Figure 2. In this case, if the disaster prevention equipment 1 is equipped with a "control unit" and an "indicator light" as its standard configuration, it can be adapted by adding a "power receiver" and modifying the standard configuration. Furthermore, the optical display structure, a technical feature of the disaster prevention equipment described in this disclosure, aims to improve visibility, making it easier to locate disaster prevention equipment that may be difficult to find in its installation environment. Therefore, the optical display structure can be installed not only on the surface of the disaster prevention equipment's main body, but also on the base installed on the ceiling or wall to which the equipment's main body is mounted. In other words, as long as the optical display structure can emit light that is visible from the outside, there are no particular restrictions on its configuration, arrangement, etc. Next, the disaster prevention equipment and disaster prevention equipment search system according to this embodiment 1 will be described in detail using Figures 2 and 3, with the case where a fire detector is used as the disaster prevention equipment 1 as a specific example.
