Abstract

The present invention relates to a fire and freeze detection and alarm system using a production support low-speed unmanned automatic guided vehicle (AGV) that supports production at an industrial site, which detects fire and freeze at the industrial site and automatically transmits a danger alarm to an industrial site control system upon detection of fire and freeze. The system implements a fire and freeze detection and alarm system using a production support low-speed unmanned automatic guided vehicle by including an unmanned automatic guided vehicle that detects the environment of the industrial site to determine fire and freeze and wirelessly transmits an alarm signal upon detection of fire and/or freeze, and an industrial site control server that is connected to the unmanned automatic guided vehicle via communication and performs real-time alarm processing upon receiving a fire and/or freeze alarm signal from the unmanned automatic guided vehicle to control real-time response to fire and/or freeze at the industrial site.

Description

Fire and freeze detection alarm system using low-speed unmanned automatic guided vehicle for production support The present invention relates to a fire and freeze detection alarm system using a low-speed unmanned automatic guided vehicle for production support. In particular, the invention relates to a fire and freeze detection alarm system using a low-speed unmanned automatic guided vehicle (AGV) that supports production at an industrial site, which detects fire and freeze at the industrial site and automatically transmits a danger alarm to an industrial site control system upon detection of fire and freeze. Automatic Guided Vehicles (AGVs) are used as part of logistics automation to automatically move goods or products within industrial workspaces. These automated guided vehicles (AGVs) recognize commands from identifiers installed on a driving guideline path pre-installed by the user and drive automatically along the path to perform tasks. The driving path of the automated guided vehicle can be defined by various means, such as wires installed below the ground or in the air, optical or magnetic tapes installed on the ground or walls, or lasers, GPS, etc. To generate a path for autonomous driving, a map of the workspace must be created. The process of creating a map of the workspace involves acquiring raw location data while driving through the workspace using navigation, processing the acquired raw data to generate node data, and connecting the generated node data to generate edge data. A map is created using the generated node and edge data, and based on the generated map information, a path is created for the AGV to perform a mission, and the generated path is transmitted to the AGV. The AGV performs the mission while autonomously driving based on the received path information. In addition, with the trend of industrial advancement, the use and handling of chemical substances in industrial sites are on the rise, and consequently, the risk of accidents is increasing. Furthermore, various causes of fire in industrial and logistics sites, such as the operation of large-scale internet e-commerce and large-scale logistics centers, are also increasing. However, conventional unmanned automated transport vehicles like the one mentioned above are only capable of transporting goods and have limitations in detecting surrounding environmental information to detect fires or freezing damage at production sites. Meanwhile, a previously proposed technology for unmanned transport vehicles is disclosed in the following <Patent Document 1>. <Patent Document 1>, based on information received from a production volume management server regarding the number of products in the first temporary storage of each primary production line and the number of products in the second temporary storage of each secondary production line, identifies the primary production line with the maximum number of products in the first temporary storage among the primary production lines, identifies the secondary production line with the minimum number of products in the second temporary storage among the secondary production lines, generates a movement path to pick up products from the first temporary storage of the primary production line and transport them to the second temporary storage of the secondary production line, and performs the transport of products based on the generated movement path. However, these conventional unmanned automated transport vehicles also have technical limitations in that they cannot provide the function to detect fires or freezing damage at production sites by sensing surrounding environmental information.
