Description

Low-power consumption water level telemetering terminating machine
Technical field
The utility model relates to a kind of low-power consumption water level telemetering terminating machine.
Background technology
At present in water resource and automatic system of hydrological data acquisition and transmission, water level telemetering is an important content of observing and predicting, and existingly observes and predicts the pattern that technology mainly is level sensor+harvester+communication apparatus+power supply, and each several part all has a variety of selection schemes.For example level sensor just has pressure type, ultrasonic type, float-type etc. respectively, the pressure type water level gauge exists temperature drift and time drifting problem, ultrasonic water level gauge is not suitable for again in the carefully observation of well water position because of the restriction of emission angle, float type level meter is the stable water level monitoring equipment of generally acknowledging, float type level meter is divided into mechanical type and photo-electric again, there are shortcomings such as wearing and tearing, loose contact in traditional mechanical type, photo-electric is contactless, can fully overcome these shortcomings, begin to be widely used in the water conservancy automatic monitoring system.Because water conservancy automatic telemetry website often is positioned at remote field environment, do not have the civil power that can conveniently insert in addition, most of solar cell or the accumulator of adopting of power devices powered, and also brought extra fund input and ruined risk.Therefore how the organic combination of each separate equipment of water level telemetering, simultaneously again can the reduction equipment volume, prolong service life of equipment, be the problem that current water level telemetering need be explored and study.
Summary of the invention
