Description
Technical field
The invention belongs to meteorologic instrument field, be specifically related to a kind of wind force monitoring device.
Background technology
Wind-force refers to the size of the strength that wind shows to object. Being typically based on wind various phenomenons produced by the object of ground or the water surface, the size of wind-force is divided into 18 grades, minimum is 0 grade, is 17 grades to the maximum.
Wind speed is the pace of wind. Draught head between adjacent two places is bigger, and air flowing is more fast, and wind speed is more big, and the strength of wind is naturally also just big. So being generally all to represent the size of wind with wind-force. The unit of wind speed with how much rice per second or per hour how many kilometers represent. And when issuing weather forecast, mostly be wind scale.
In order to measure wind-force size more accurately, wind surveyed by people's conventional pocket anemometer in the wild. This pocket anemometer, is generally made up of sensing part sum counter. Sensing part is loaded on cross by three vanes (also having four vanes), and vane can be freely rotatable on bearing, the little frame protection vane of external. Axis bottom connects with enumerator, and vane rotates, and also makes enumerator concomitant rotation. So enumerator is the revolution that record vane rotates. Enumerator generally has two or three numeration dishes, and big pointer indicates a position and tens, and the pointer on two little numeration dishes indicates respectively hundreds and units. One switch (starting bar) is arranged at the bottom of instrument, it is pushed to, and enumerator can be made to engage with sensing part, and enumerator is started working. Starting bar being pulled down enumerator then leave with sensing part, enumerator quits work. When instrument is placed in eminence, directly starts inconvenience with hands, available marline connecting valve. Marline is pulled and able to turn on or off during observation. Pocket anemometer is generally mounted to that surrounding is open, place without tall and big barrier, and table body is vertical. Closing switch before observation, writes down the registration of pointer. After one or two minute, open switch, start the stopwatch record time simultaneously. Now, anemoclinograph observation person speeds away anemometer, stands in the leeward of instrument. When starting after instrument nearly 100 seconds, observation person walks close to rapidly instrument, the closing switch when positive 100 seconds, writes down second time pointer registration. Calculating its difference according to twice, front and back reading, this difference represents the number of division that anemometer pointer is walked in observation time, charges in log. By this difference divided by observation time, the number of division walked in anemometer each second must be gone out, take a decimal. Further according to walked number of division per second, demonstrate,prove from the calibrating of this anemometer and find mean wind speed (unit: meter per second), take a decimal. Best Continuous Observation twice, takes its meansigma methods, to reduce instrument itself and artificial error.
Some light anemoscope, except the structural behavior with the anemometer said above, also equipped with wind vane on axle, in order to indicate wind direction, is called anemoclinograph.
