Description
Technical field
The present invention relates to a kind of method and apparatus of measuring rainfall.
Background technology
Rain gage is the equipment that is used to measure rainfall amount that department and fields such as meteorology, the hydrology, various water conservancy projects, mine, railway and easily taking place must be installed on the landslide of geologic hazard.At present, the equipment of metering rainfall amount adopts tipping-bucket rain-gauge or siphon rainfall recorder (Ma Xianghua, the red steel of clothing, Chen worker, Hu Shanzhi, the digital transducer application in Hydrology Telemetric System, the sensor world, Dec calendar year 2001) mostly.Tipping-bucket rain-gauge is made up of major parts such as holding the mouth of a river, filtration unit, top cylinder, attachment screw, magnet steel, the yellow pipe of dry type tongue, doffing, tipping bucket, stop screw, set nut, base, air level, levelling bolt, hold the rainwater that collect at the mouth of a river, through top cylinder (funnel) filtration unit, inject the metering tipping bucket, the metering tipping bucket makes with engineering plastics, the centre is divided into two isometric triangle small rooms with dividing plate, it is a mechanical bistable structure, when a small room water receiving, another small room is in waiting status.When connecing rainwater volume reaches predetermined value, because action of gravity makes own overturning, be in waiting status, another small room is in the water receiving duty.When its water receiving amount reached predetermined value, own again overturning was in waiting status.On the tipping bucket sidewall, magnet steel is housed, when stirring with tipping bucket, it scans from the yellow pipe of dry type tongue side, make the yellow pipe of dry type tongue break-make, be the every overturning of tipping bucket once, the yellow pipe of dry type tongue is just connected once, sending a switching signal is pulse signal, tipping bucket stirs the pulse signal numeration that number of times is sent with the yellow pipe of magnet steel scanning dry type tongue break-make, pulse signal of every record is just represented the rainfall of 0.1mm, realizes the purpose of rainfall remote measurement.Because it is based on the tipping-bucket rain-gauge of mechanical principle design, be to come the accommodometer accuracy of measurement by regulating mechanical equilibrium, since mechanical realization intrinsic and inertial force and resistance that can't eliminate, make that this udometric degree of accuracy and resolution are low, promptly for trickle rainfall it can not record, it has little time upset and for heavy rain, heavy rain, rainfall record error of omission or few note appear, and rainfall is big more, the continuous rainfall time is long more, record is just inaccurate more, and the measurement deviation that is produced is also just big more.Make meteorological department to most important parameter index on " rainfall amount " this meteorology and the hydrology, rest on the substandard stoichiometric level of " can not truly reflect the rainfall amount data " always.And siphon rainfall recorder is the method that adopts manual observation mostly, and is not too convenient in the application, and can't realize the automatic transmission of rainfall amount data.
Summary of the invention
At above-mentioned present situation, the object of the present invention is to provide the method and apparatus of a kind of measuring accuracy height, measurement rainfall that no matter the rainfall amount size can both accurately be measured.
The object of the present invention is achieved like this:
A kind of method of measuring rainfall, this method may further comprise the steps: at first make rainwater enter funnel, water inlet pipe under funnel flows into reservoir chamber then, float in the reservoir chamber is floated, then the displacement of measuring float by angular displacement sensor be rainfall amount and by data transmission device with this rainfall amount data transmission to rainfall Monitoring and Controlling administrative center.
Further, the described rainwater that enters funnel enters reservoir chamber by water inlet pipe again behind entering water electromagnetic valve, and the water yield in reservoir chamber is emitted by the solenoid valve that discharges water when arriving predetermined value.
A kind of device of measuring rainfall, comprise the funnel, water inlet pipe, reservoir chamber and the water surface displacement measuring device that are arranged in the shell, the funnel lower end is provided with water inlet pipe, water inlet pipe is connected with reservoir chamber, be provided with water surface displacement measuring device in the reservoir chamber, be provided with entering water electromagnetic valve between described funnel and water inlet pipe, be provided with the solenoid valve that discharges water on described reservoir chamber, entering water electromagnetic valve, the solenoid valve that discharges water are connected with power supply.
Further, described water surface displacement measuring device comprises the float on the water surface that can be suspended in the described reservoir chamber, and the other end of the rope on this float is connected with counterweight, and this rope also is connected with angular displacement sensor.
Further, described angular displacement sensor is fixed on the reservoir chamber by support, and described float and counterweight are divided into the support both sides.
Further, be provided with filtration unit between described funnel and the entering water electromagnetic valve.
Further, described entering water electromagnetic valve is the open type entering water electromagnetic valve.
Further, the described solenoid valve that discharges water is the closed type solenoid valve that discharges water.
Further, described angular displacement sensor is simply connected conductive plastics angular displacement sensor or duplex conductive plastics angular displacement sensor or angular encoder or grating angular displacement sensor or magnetic resistance angular displacement sensor.
The invention has the advantages that: because the funnel lower end of this device is provided with entering water electromagnetic valve, reservoir chamber is provided with the solenoid valve that discharges water, therefore, even discharge water in the process of rainfall, rainfall amount does not have any error yet, has guaranteed to measure when heavy rain, heavy rain accurately; In addition, owing to adopted little and the displacement that angular displacement sensor that sensitivity is very high is measured the water surface of driving torque, the diameter that can be by changing the sensor rotor wheel and the diameter of float make the measuring accuracy of this measurement mechanism very high; In addition, in the process of rainfall,, make that the output valve of sensor is also highly stable, thereby guaranteed the accurate measurement of rainfall amount because the rising of float is highly stable; Also can in real time rainfall amount be transferred to rainfall Monitoring and Controlling administrative center if make angular displacement sensor connect radio transmitting device, but and the rainfall amount of real time record and storage per minute, can overcome rainfall measuring apparatus commonly used can't be with the self-propagating problem of rainfall amount data.
