Abstract

A remote management system and method are provided that can more reliably determine the status of an object, such as a barrier, while avoiding the limitations of wireless communication, and also suppress energy consumption during the determination process. A sensor (2) and a transmitting/receiving terminal (3) operated by a battery (4) are installed in each of the radiators (9), and when the detection data (M) by each sensor (2) is transmitted to a relay device (5A) by radio waves (W) from each transmitting/receiving terminal (3), communication is used based on a predetermined LPWA communication standard. When the communication strength (S) between each transmitting/receiving terminal (3) and the relay device (5A) is greater than or equal to a reference value (Sc), it is transmitted via a direct route (Rd) from each transmitting/receiving terminal (3) to the relay device (5A). When it is less than the reference value (Sc), it is transmitted via a bypass route (Rb) in which another transmitting/receiving terminal (3) is interposed between each transmitting/receiving terminal (3) and the relay device (5A). A management indicator based on the detection data is stored in a server (5B), and the management indicator is displayed on specific devices (6a, 6b, 6c) that can access the server (5B).

Description

Remote management system and method for an object The present invention relates to a remote management system and method for objects, and more specifically, to a remote management system and method for objects that, when determining the status of a plurality of objects such as a fire fin, can determine the status of each object more reliably while avoiding the limitations of wireless communication, and can also suppress energy consumption in the process of determining the status of each object. Various monitoring systems have been proposed that acquire detection data from a pressure sensor installed inside an air-type fender via wireless communication and determine the state of the air-type fender based on the acquired detection data (internal pressure data) (see, for example, Patent Documents 1 and 2). In these monitoring systems, power from a battery placed in the fender is used to operate the pressure sensor or perform wireless communication. Since the battery placed in the fender cannot be replaced frequently, it is necessary to suppress the battery's power consumption. However, suppressing the battery's power consumption and lowering the frequency of wireless communication or the frequency of acquiring detection data is disadvantageous for accurately determining the state of the fender. Generally, since multiple fenders are deployed within a single area, the communication distance between the wireless communication device and a fender located far away becomes significant. This can result in situations where wireless communication is impossible or where the battery power consumption for wireless communication becomes excessive. Therefore, to ensure stable wireless communication, it is necessary to move the wireless communication device to a location closer to each fender. However, for example, moving a vessel equipped with a wireless communication device to bring it closer to multiple fenders installed at an offshore facility consumes a corresponding amount of fuel. Thus, to more reliably monitor the status of each fender deployed across a wide area, energy consumption, such as batteries and fuel, increases. Furthermore, there are various restrictions (legal regulations) on wireless communication. These issues of increased energy consumption and wireless communication restrictions are not limited to air-powered fenders but also occur when monitoring marine hoses or belt conveyor systems. Therefore, a special design is required to avoid wireless communication restrictions, more reliably monitor the status of the target object, and further suppress energy consumption during the monitoring process.
