Intelligent alarm rain gauge

Abstract

The invention relates to an intelligent alarm rain gauge, which comprises a rain gauge, an alerter and a measuring cylinder, wherein the lower part of the measuring cylinder is provided with a water drain valve and a pressure sensor; the pressure sensor is connected with the alerter and is installed on a fixed seat, and the pressure sensor is connected with the alerter through a cable; and the alerter comprises a case, an LED (Light-Emitting Diode) display screen installed on the case, and a control circuit installed in the case. The intelligent alarm rain gauge has the advantages of simple structure, small size, no pollution, light weight, long service life and low standby power consumption and can not be polluted or corroded by dust, greasy dirt, moisture, salt mist and the like. The intelligent alarm rain gauge has the characteristics of simplicity in installation, convenience in maintenance and more humanized operation, and the intelligent alerter can be externally connected with a simple rain gauge or tipping-bucket rain gauge. A communication mode adopts standard RS485 communication. The intelligent alarm rain gauge also has the advantages of stable running, high reliability, high compatibility, high accuracy of measured values, small temperature drift and small influence from environmental factors.

Description

technical field [0001] The invention relates to a rain gauge, in particular to an intelligent alarm rain gauge. Background technique [0002] The existing rain gauge can only simply measure the rainfall, and can only observe the rainfall manually, which cannot meet the needs of information transmission, processing, recording and display, and has no function of preventing flood disasters, so it is inconvenient to use, and when an accident occurs When floods and rains occur, the police cannot be called in time, and there are potential safety hazards. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an intelligent alarm rain gauge that can accurately measure rainfall and output the rainfall to an alarm device in the form of an electrical signal, which is convenient for remote monitoring. [0004] The purpose of the present invention is achieved in this way: an intelligent alarm rain gauge, comp...
