Description
Affiliated technical field:
The present invention relates to a kind ofly for udometric detecting instrument, mainly is detection, fault diagnosis and the calibration of tipping-bucket rain-gauge.
Background technology:
Tipping-bucket rain-gauge or rain sensor are the most widely rainfall record devices of present domestic application, generally use in units such as meteorology, the hydrology, agricultural, airports.Because long term exposure is environment out of doors, udometric precision changes unavoidably, therefore must regularly detect and calibrate, to guarantee the accuracy of precipitation measurement data.
Udometric general detection method is, get gauge water, make its at the appointed time length flow into the udometric hyponome that holds according to fixed speed, thereby simulate the Precipitation Record value of the precipitation environment rainfall meter of different raininess, and can determine udometric order of accuarcy behind the calibration value.
Existing rain gage testing calibration device is divided into outdoor on-site detecting device and indoor pick-up unit according to use occasion, and these two kinds of devices have following different defectives:
On-the-spot rain gage testing calibration device before this generally all relies on manual detection or simply adds counter, concrete grammar is to get a certain amount of water, by manual control or adopt flow-limiting valve gate control water at the appointed time length flow into rain gage, thereby simulate the working condition of different raininess rainfall meters.This series products has following defective: (1) degree of accuracy is relatively poor, and the water velocity front and back differ greatly, time of flow length is unstable, can't simulate accurately different raininess; (2) substantially by manually-operated, numerous and diverse time-consuming, take manpower; (3) affected by operator's human factor larger in data acquisition, and maloperation occurs sometimes unavoidably, and uncertain factor is more; (4) can not automatically set up file store, be difficult to guarantee to detect for a long time the complete of archives; (5) pick-up unit self precision changes in time, and impact detects effect.
The pick-up unit that some indoor uses are arranged before this although precision has certain assurance, exists again automaticity low, and volume is large, Heavy Weight, and software function is not comprehensive, and cost is high, particularly can't be used for the defectives such as outdoor Site Detection.
Summary of the invention:
The purpose of this invention is to provide a kind of full-automatic intelligent rain gage detection scheme by computer control, can accurately control the speed of current to guarantee accuracy of detection, simultaneously again can AC/DC, both can be used for outdoor Site Detection, can be used for again indoor detection.
Basic skills of the present invention is to control charging pump, solenoid valve with computer, from the rainfall standard ball, take out the water yield of demarcating, by peristaltic pump standard flow rate in accordance with regulations water is injected rain gage again, thereby simulate the ruuning situation of different raininess rainfall meters and record detected value, judge udometric levels of precision and instruct when needed the operator that it is debugged and calibrates.

Be connected with threeway by water pipe between the charging pump of prover main frame, rainfall standard ball, the water storage case, and by the switching in solenoid control water route.Water storage case has water pipe to be connected to peristaltic pump in addition, and is drawn water by peristaltic pump and to export to rain gage.The gap access spilling water ball of rainfall standard ball top, spilling water ball below connects overflow pipe.Solenoid valve, charging pump, peristaltic pump are connected to control module by circuit, and control module carries out communication by wired or wireless mode and computer.The prover cabinet has upper hose and overflow pipe to be connected to the water source outward, also has rising pipe to be connected to rain gage, and the control circuit unit has signal wire to be connected to udometric signal binding post to carry out data acquisition in addition.
During detection, computer sends instruction unpack charging pump and upper water solenoid valve, draws water from the water source and injects the rainfall standard ball, and the completely rear gap by the top of water overflows, and flows back to the water source through spilling water ball and overflow pipe, and charging pump and water supply valve are closed; Then computer sends the instruction unpack water supply electromagnetic valve, water in the rainfall standard ball flows into water storage case, until the liquid level in the rainfall standard ball drops to the height of water delivering orifice in the water storage case, the water yield in the water storage case is the standard water yield of a detecting unit at this moment, and water supply electromagnetic valve is closed; Computer sends instruction makes peristaltic pump according to the speed operation of setting, and the water that extracts in the water storage case is sent into the udometric hyponome that holds, and receives simultaneously the data of passing back on the continuous signal wire of rain gage, until the current in the water storage case are complete, one-time detection finishes.Computer program detects number of times according to every kind of raininess of former setting afterwards, automatically repeats to finish whole detections, and building database forms calibration certificate.
The present invention and similar device relatively have following advantage:
(1) degree of accuracy is high, by the rainfall standard ball supply water guaranteed rainfall accurately, solved the measurement standard problem of tracing to the source; Computer control peristaltic pump guarantees that flow velocity is even from start to finish, and can change arbitrarily flow velocity and simulate any raininess; Send the water time span accurate, guarantee the accurate of raininess; The overall process computer is automatically finished and has been got rid of various disturbing factors and maloperation possibility.
(2) automaticity is high, and each step of detection is all finished by computer control, until detection finishes, building database is produced calibration certificate and be need not manually-operated, has liberated to greatest extent manpower from beginning upper water.
(3) software function is comprehensive, not only can accurately control testing process, and the data that gather are more detailed accurately, disclose the microprocess of rain gage operation, and can make intelligent fault diagnosis to rain gage on this basis, and guide the operator according to data rain gage to be calibrated.
(4) stability is high, and system is the error of correction itself voluntarily, guarantees that the variation of the extraneous factors such as permanent use or replacing parts can not affect the detection quality.
(5) volume is little, and is easy to carry, 10 kilograms of shortages in weight.
