Description

This invention relates to a reservoir monitoring device and reservoir monitoring and notification system that monitors the water level of a reservoir and provides notifications as needed. Normally, the water in reservoirs does not flow into rivers or other bodies of water. Therefore, if a reservoir overflows due to heavy rainfall and breaks its banks, it could cause damage to surrounding houses and residents. For this reason, cameras and water level gauges have traditionally been installed in reservoirs, transmitting camera images and water level data to municipal offices. These offices then determine whether evacuation warnings are necessary. If necessary, information is then provided to residents via the municipal website or public address system. Furthermore, a reservoir leak detection system is known that does not require past observation data and can be operated immediately after installation (see, for example, Patent Document 1). This system comprises a water level information acquisition means for measuring the reservoir's water level, and a calculation means for determining the presence or absence of a leak based on the difference between the water level measured by the water level information acquisition means and a pre-calculated reference water level. If the calculation means determines that a leak exists, it transmits this information to the mobile devices of residents near the reservoir. Japanese Patent Publication No. 2016-173310 This is a schematic diagram showing a reservoir monitoring device and reservoir monitoring notification system according to an embodiment of the present invention.Figure 1 is a flowchart showing the operation flow of the alarm task of the reservoir monitoring device.Figure 1 is a schematic block diagram showing the reservoir monitoring server of the reservoir monitoring and notification system.Figure 3 is a flowchart showing the operation flow of the monitoring task on the reservoir monitoring server. The present invention will be described below based on the illustrated embodiments. Figure 1 is a schematic diagram showing a reservoir monitoring device 1 and reservoir monitoring and notification system 10 according to an embodiment of this invention. The reservoir monitoring device 1 and reservoir monitoring and notification system 10 are a device and system for monitoring the water level of reservoirs T and providing notifications as needed. The reservoir monitoring device 1, installed at each reservoir T, and the reservoir monitoring server 6 are communicated with each other. Here, the reservoir monitoring server 6 may be installed anywhere, but for example, it is set up at a municipal office that monitors and manages multiple reservoirs T. The reservoir monitoring device 1 mainly comprises a camera (water level monitoring means) 2, a water level gauge (water level monitoring means) 3, an FM broadcaster (FM broadcasting means) 4, and a control device (alarm determination means) 5. The camera 2, FM broadcaster 4, and control device 5 are mounted on a support column P located near the reservoir T, while the water level gauge 3 is mounted in the reservoir T. The control device 5 is also connected to the camera 2, water level gauge 3, and FM broadcaster 4 for data transmission. Camera 2 continuously photographs the reservoir T and monitors its water level, transmitting the captured images to the control device 5 in real time. Similarly, the water level gauge 3 continuously measures the water level of the reservoir T and monitors its water level, transmitting the measured water level to the control device 5 in real time. Furthermore, the control device 5 periodically transmits images from camera 2 and water level data from water level gauge 3 to the reservoir monitoring server 6, regardless of whether or not an alarm is triggered (as described later). The FM radio transmitter 4 is a transmitter that broadcasts voice messages via FM radio in response to alarms and other signals detected by the control device 5, as described later. Specifically, it is equipped with a sound source that stores multiple voice messages. When the control device 5 transmits the type of alarm, the transmitter selects a corresponding voice message from the sound source and broadcasts it via FM radio. For example, if an evacuation warning alarm is transmitted from the control device 5, it will broadcast a voice message such as, "An alarm has been triggered at the XX reservoir; please evacuate." Then, radio receivers R installed in houses H and other buildings around the reservoir T receive this FM radio broadcast, allowing residents M to hear the voice message. In this embodiment, the radio receiver R automatically activates when the FM broadcaster 4 broadcasts the voice message. That is, prior to the broadcast of the voice message, the FM broadcaster 4 sends an activation signal, which the radio receiver R receives and activates automatically. The broadcast range of the FM broadcaster 4 is set to
