Description

Method, Apparatus and System for Fire-Device-Based Electric Control Linked with Fire Protection Equipment The following embodiments relate to technology for electrical control interlocked with fire fighting equipment. Recently, rapid and accurate responses to fires are required in various environments, such as buildings, industrial facilities, logistics centers, ships, and data centers. In particular, in environments where electrical equipment and lighting fixtures are installed in combination, it is difficult to prevent the spread of damage through fire suppression alone. Cases are frequently reported where fires spread through electrical wiring or power supply lines, or where secondary fires occur due to heat generated by lighting fixtures. Conventional fire prevention systems are primarily limited to operating based on a single sensor or activating only firefighting equipment after detecting a fire. For example, when smoke or a temperature rise is detected in a specific area, sprinklers or alarm devices are activated, and power cutoff or lighting control in that area is often performed manually. This method has limitations, such as a slow initial response speed, low accuracy of detection signals, and difficulty in preventing secondary damage caused by electrical factors. Furthermore, fire detection relying solely on simple smoke or temperature sensors has a high false positive rate, which can lead to unnecessary activation of firefighting equipment or power outages. Accordingly, technologies utilizing thermal imaging cameras to analyze the likelihood of fire more precisely are being introduced. However, since sensor data and thermal imaging data are operated separately or each piece of information is evaluated independently, there are limitations to complex situational analysis and integrated control. Therefore, there is a growing need for integrated control technology capable of accurately detecting fire zones by collecting various data and comprehensively determining fire occurrences based on them. Additionally, there is an increasing necessity for an integrated fire prevention and control system that prevents fire spread and facilitates evacuation by automatically cutting off power supply to detected fire zones and switching lighting fixtures in those areas to warning lights. Consequently, the implementation of related technologies is required. FIG. 1 is a schematic diagram showing the configuration of a system according to one embodiment.
