Weighing-type telemetering rain gauge capable of discharging water automatically

Abstract

A weighing-type telemetering rain gauge capable of discharging water automatically includes a rain barrel, a funnel, a water storage funnel, a water storage barrel, a submerged pump, a weighing tray, a weighing sensor and a collection processor. The funnel and the water storage funnel are fixed in the upper part of the rain barrel. The water storage barrel is disposed on the weighing tray in the rain barrel. The weighing tray is disposed on the weighing sensor. The water storage funnel is connected with the submerged pump through a water inlet pipe. The water inlet pipe is provided with a stop valve. A water outlet in the water inlet pipe below the stop valve is connected with a water outlet in the rain barrel through an exhaust pipe. The data collection processor includes a short text message module, a clock module, an LED display screen storage module, a single-chip microprocessor, a D / A conversion module, a relay module and a power source weighing module. According to the invention, rainfall collection precision is improved. The weighing-type telemetering rain gauge is simple in structure and does not need manual intervention, and the operation cost is low.

Description

technical field [0001] The invention relates to a weighing type remote measuring rain gauge with automatic drainage, in particular to a weighing type rain gauge using a submersible pump for automatic drainage. Background technique [0002] At present, the methods of measuring rainfall at home and abroad mainly include the following types, siphon method and tipping bucket method. Among them, the siphon rain gauge was the first to be promoted and used in my country, and it is mainly used in grass-roots hydrological stations. However, with the development of information transmission automation, its shortcomings of being unable to realize automatic collection and remote transmission have become more and more obvious. In recent years, it has been gradually eliminated and replaced by automatic collection and transmission equipment such as tipping bucket rain gauge and weighing rain gauge. The tipping bucket rain gauge is the most widely used telemetry rain gauge in my country at ...

Problems solved by technology

However, with the development of information transmission automation, the shortcomings of its inability to realize automatic collection and remote transmission have become more and more obvious. In recent years, it has been gradually eliminated and replaced by automatic collection and transmission equipment such as tipping bucket rain gauges and weighing rain gauges.

The tipping bucket rain gauge is the most widely used telemetry rain gauge in my country at present, and its operation is relatively stable, but it also has many influencing factors that affect its measurement accuracy. ; What is more serious is that when the rainfall exceeds a certain value, the tipping bucket is not turned in time, resulting in the loss of rainfall data, which seriously affects the accurate measurement of rainfall and the statistics of hydrological data
