Abstract
The utility model provides a udometer with small error and simple mechanical structure. The udometer mainly comprises a shell, a water catchment funnel, a water cylinder, a floating ball and so on. The water inlet of the water cylinder is provided with a water-feeding solenoid valve that is often open; the water outlet of the water cylinder is provided with a drainage solenoid valve that is often closed. The udometer also comprises a microcomputer processing unit that consists of a capacitive ruler and a single-chip; the capacitive ruler is arranged on the floating ball; the synchronous lifting movement of the capacitive ruler and the floating ball can be used for detecting the water level and transmitting the signals of the water level to the single-chip of the microcomputer processing unit. After being calculated and processed by the single-chip, the signals of rainfall can be exported from the output port. The microcomputer processing unit controls the corresponding movement of the drainage solenoid valve and the water-feeding solenoid valve.
Description
Technical field
The utility model relates to a kind of rain gage.
Background technology
At present, rain gage is based on tipping bucket type physical construction, is made of water container, last tipping bucket, metering tipping bucket, counting tipping bucket, collecting funnel, set screw, tongue tube etc.When the water yield that its principle of work contains when last tipping bucket reaches certain quantitative value, last tipping bucket overturning, another tipping bucket begins to contain rainwater, and the overturning rainwater flows into the metering tipping bucket through collecting funnel.Long-pending during to suitable 0.1 millimeter precipitation when metering tipping bucket rainfall, the overturning of metering tipping bucket is poured rainwater into the counting tipping bucket, and the counting tipping bucket is stirred once.Because the rain gage of this class formation adopts the mechanical principle design, requirement to balance during installation is very strict, simultaneously because the intrinsic inertia of machinery upset, can not count when making micro-rainfall, cause the loss of rainfall and have little time to overturn heavy rain the time, so make udometric error in dipping increase greatly.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of error is little, the simple rain gage of physical construction.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of rain gage, mainly constitute by housing, the funnel that catchments, the cylinder body that is filled with water, ball float etc., it is characterized in that: the water inlet of the cylinder body that is filled with water is provided with entering water electromagnetic valve, the water delivering orifice of cylinder body of being filled with water is provided with drain solenoid valve, entering water electromagnetic valve is a normally open solenoid valve, and drain solenoid valve is a normally closed solenoid valve; Also comprise one by holding the computer processing unit that grid chi and single-chip microcomputer are formed, the appearance grid chi of computer processing unit is loaded on the ball float, hold grid chi and ball float synchronization lifting motion detection water level and carry the single-chip microcomputer of water level signal in computer processing unit, for output, computer processing unit control drain solenoid valve and entering water electromagnetic valve are made corresponding actions to output rainfall signal in output port after the single-chip microcomputer calculation process.
The beneficial effects of the utility model are: adopted computer processing unit the water level information that holds the detection of grid chi to be carried out the structural design of computing and processing controls and bivalve, make the degree of accuracy that rainfall is measured improve greatly, obtain rainfall telemetry accurately, and by computer processing unit when water level reaches the upper limit or lower limit, control drain solenoid valve and entering water electromagnetic valve, and need not to be provided with again upper and lower limit switch, the purpose that has not only simplified the structure but also realized and accurately measured the amount of rainfall.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is the structural scheme of mechanism of the udometric a kind of embodiment of the utility model.
Embodiment
As Fig. 1, the udometric a kind of embodiment of the utility model, described rain gage comprise housing, the cylinder body 6 that is filled with water, the funnel 1 that catchments, ball float 7 and by holding the computer processing unit that grid chi 10 and PIC single-chip microcomputer 5 are formed.The water inlet of cylinder body 6 of being filled with water is provided with entering water electromagnetic valve 3, and the water delivering orifice of the cylinder body 6 that is filled with water is provided with drain solenoid valve 4, and entering water electromagnetic valve 3 is a normally open solenoid valve, and drain solenoid valve 4 is a normally closed solenoid valve.The appearance grid chi 10 of computer processing unit is loaded on the ball float 7, hold grid chi 10 and ball float 7 synchronization lifting motion detection water levels, and carry water level signal in the PIC of computer processing unit single-chip microcomputer 5, by PIC single-chip microcomputer 5 with the water level signal calculation process after output rainfall signal in output port 8.
Entering water electromagnetic valve 3 is shown in an open position under the normality, and the rainwater of landing is sent into the cylinder body 6 that is filled with water by entering water electromagnetic valve 3 after the funnel 1 that catchments is collected, and this moment, drain solenoid valve 4 was in closed condition.The cylinder body 6 interior water levels that are filled with water rise and drive ball float 7 risings, hold grid chi 10 and ball float 7 synchronization lifting motion detection water levels, and the PIC single-chip microcomputer of computer processing unit reads the water level signal on the appearance grid chi 10; When if water level reaches the upper limit or lower limit, computer processing unit control drain solenoid valve and entering water electromagnetic valve are made corresponding actions, be that water level reaches the upper limit, the PIC single-chip microcomputer of computer processing unit transmits control signal and makes entering water electromagnetic valve 3 cut out, drain solenoid valve 4 is opened, the cylinder body 6 interior rainwater that are filled with water are discharged through drain solenoid valve 6, the rainwater that the funnel 1 that catchments in drainage procedure is connect is kept off outside the cylinder body 6 that is filled with water by entering water electromagnetic valve 3, along with rainwater is discharged from outside the cylinder body 6 that is filled with water, ball float 7 also descends synchronously, decline of water table on holding the grid chi is during to smallest limit, and the PIC single-chip microcomputer of computer processing unit transmits control signal and makes entering water electromagnetic valve 3 open, drain solenoid valve 4 is closed; If water level does not reach the upper limit or lower limit, holding the scale signal of grid chi gives computer processing unit interior PIC single-chip microcomputer, the PIC single-chip microcomputer this signal by computing, convert rainfall data to, the PIC single-chip microcomputer is delivered to output port 8 to rainfall data, and output port 8 can send the rainfall signal in the usefulness of indoor telemetry host computer demonstration, Treatment Analysis by wired or unlimited mode.Rain gage is finished the overall process to the rainwater metering under the programmed control of PIC single-chip microcomputer thus.Wherein upper table 2 and lower table 9 are used for the usefulness of installing and fixing each parts.
