Abstract

The breaking of soil dams always happens unexpectedly and spontaneously. At the same time, accidents of and damage to pressure head soil constructions or their separate parts are caused not only by the wrong selection of a dam type or a mismatch to their specific conditions of operation or by violations or defects of construction, but also maintenance errors, which, naturally, can lead to negative consequences. When accidents of soil dams happen spontaneously, there is a very short time window for deciding whether to evacuate the population. Therefore, for timely annunciator about emergency situation still topical are the issues of enhancement and development of the modem warning systems in a flooding zone where it is proposed to install information posts, in the lower part of which sensors will be located, and in the upper part there will be an antenna, transmitting a signal to the control desk of a local emergency officer on duty. When the sensor is flooded, there is a short circuit in a circuit and the signal from the transmitter arrives to the control desk of an officer on duty with number of a pole. The officer on duty analyzes data the retrieved, and, if the number of the poles signaling flooding is greater than three, then the emergency officer starts a siren that sends a signal to the system of central alarm and a siren in the inhabited area will signal that there is danger of flooding. This article considers a system that has been developed of an emergency signaler consisting of a primary signaling unit located near a hydroconstruction or possible direction of movement of waterflow and a secondary signaling unit located in the inhabited area at the boundary of possible movement of a break wave, which, through the intermediary of a computer information system, sends an SMS about the presence of a crisis state to subscribers registered in a zone of possible flooding.
