Description
The utility model relates to a kind of electronic device of measuring air flow field, the automatic Acquisition Instrument of especially a kind of wind speed and direction.
The mensuration of wind speed and direction has great significance to research and railway, the observation of highway engineering sand prevention benefit of oasis shelter-forest benefit, formation with its research aeolian landform, changing and being provided with that artificial measures for sand prevention and shelter-forest set up is one of the data that must measure, so this instrument is widely used in the research of aspects such as aeolian landform, ecology, meteorology, agricultural, forestry, railway, highway, reservoir engineering sand prevention.
Using three glasss (four glasss) sense wind sensor and double leaf wind direction mapping wind is the method that generally adopts both at home and abroad at present.Its principle is: when air-flow was executed on cup, it was poor to produce moment because of the suffered pressure of vane protuberance and recess is different, vane rotation under the effect of moment difference, and its speed depends on the speed of air-flow.When air-flow was executed on the double leaf weathervane, the fan blade identical air-flow that is under pressure in the left and right sides made weathervane point to the windward side, and fan blade remains unchanged, and its weathervane changes the direction that depends on wind speed.
From above-mentioned principle, the measuring method of commonly using both at home and abroad is horizontal or vertical several hand anemometers that is provided with in observation field, all be that this not only makes the observation personnel feel the epitonos fatigue by artificial reading, but also have following shortcoming problems significantly:
1. observation personnel's scene exists and is movable, and the objective regularity of distribution of each key element field of state of nature of meeting havoc experiment place underlying surface makes obtained data information lose representativeness.
2. the artificial observation reading also has very big subjectivity, can cause artificial reading error, in addition occur sometimes mispronouncing, phenomenon such as incorrect posting.
3. the artificial observation rate of reading is slow, can't gather reading simultaneously to the multichannel wind speed and direction, and this will cause the data information of gained to lack simultaneity and comparative.
4. the data information that artificial observation obtained is by manually making a copy of, counting statistics, and speed is slow, efficient is low, can't obtain " in real time " result.
Along with the needs and the development of research, this anemometer can not adapt to the observation needs.Domestic a few years ago existing development anemometry instrument, for example: Changchun meteorologic instrument factory and desert, Lanzhou the interlock anemometer of common development, control the action of each anemometer with electrical means, it is many that operating personnel have been reduced.But present existing anemometer still adopts artificial reading, and hand-kept does not have wind direction to measure and functions such as the sampling time is adjustable, data-storing, printing.Volume is big, way is few, power consumption is big, can not continuous acquisition wind speed and direction data.Obvious this anemometer also has artificial error, is difficult to reach the purpose of accurate measurement.
The purpose of this utility model is for a kind of measuring accuracy height is provided, synchronously continuous acquisition show different time every wind speed, wind direction, the measurement way is many, volume is little, intellectuality by force, the automatic Acquisition Instrument of wind speed and direction fast, easily.The purpose of this utility model can realize by following measure:
The automatic Acquisition Instrument of a kind of wind speed and direction contains weathervane, wind speed induction cup, Hall element, data acquisition circuit, LCD display circuit, data-storing circuit, printer interface circuit, keyboard circuit, clock circuit, magnet etc.; On fixed mount, be provided with weathervane and wind speed induction cup, in the weathervane rotating shaft, be fixedly connected with magnet, and under the magnet of weathervane rotating shaft, be with the wind direction price fixing of band Hall element; In the rotating shaft of wind speed induction cup, be with the wind speed rotating disk of carry magnet in addition, be provided with Hall element at wind speed rotating disk side; The electric signal of Hall element is measured control processing circuit with wind speed and direction and is linked to each other.
The purpose of this utility model also can realize by following measure:
The wind speed and direction of the automatic Acquisition Instrument of described wind speed and direction is measured control processing circuit and is made up of single-chip data acquisition circuit, LCD display circuit, data-storing circuit, printer interface circuit, keyboard, clock circuit.
The power supply that described wind speed and direction is measured control processing circuit also can adopt solar cell generation electric energy to be linked by charging circuit and accumulator, produces stabilized voltage supply by voltage stabilizer again.
The utility model has following advantage compared to existing technology:
1, the automatic Acquisition Instrument of multichannel sand prevention wind speed and direction that provides of the utility model is direct-reading and data-storing formula, it is by the special debugging of circuit, the number of turns and direction with vane and weathervane, convert air speed value and wind azimuth value to highly sensitive Hall switch circuit, overcome the cumbersome formality of the manual record in the prior art.
2, sand prevention function admirable of the present utility model owing to do not had mechanical resistance and clock gear rotating part, reduces the mechanical friction power of vane, and measurement range is enlarged, and the sand prevention performance also is much improved.
3, intelligent wind measuring system of the present utility model is by the software operation programmed control, use a computer the software resource of 80C31 is developed, will survey the fetch preface and be cured in the single-chip microcomputer EPROM memory, increased the function of instrument, reduce hardware circuit, improved the reliability of instrument.
4, its measurement range of the automatic Acquisition Instrument of multichannel wind speed and direction of providing of the utility model is 0.6～40m/s, weathervane 0～360.Divide 16 orientation, passing changes distance greater than 300 meters.Owing to adopted Cmos minitype single-chip computer technology and low power consumption Cmos device, power consumption is very little, so instrument is by the 12v storage battery power supply, by rechargeable solar battery, makes the volume of instrument little, in light weight, and it is open-air extremely easy to use to be easy to carry.
