Description
Technical Field
The invention relates to the field of meteorological environment monitoring, in particular to a dynamic self-level orthogonal wind speed measuring meteorological device.
Background
Since 1999, China began to introduce a lot of meteorological observation devices from Finland, and the introduction of the devices and the establishment of related measurement systems mark that the meteorological detection of China is opening a new era. Automatic weather observation technology was then developed vigorously, and in 2000, the first batch of equipment was put into operation formally. So far, China has become a country with a plurality of observation devices, and a relatively perfect system is established, so that automatic acquisition of meteorological data can be realized, and rapid real-time transmission can be carried out[7]。
Since many observation devices in China have been imported, it is important to produce meteorological devices autonomously today when meteorological data becomes important. At present, China has a plurality of observation equipment manufacturers, and the manufacturers are units which are inspected by the China weather bureau to be qualified. For example, the CAWS-600 series produced by Beijing Hua Chuangshengda high-tech development company, and DYYZ-II series from Changchun instruments, have excellent performance and many functions. The autonomously developed automatic weather observation equipment can be used and popularized in China weather in a large amount, so that the development of China automatic weather stations is full of flowers. Have been vigorously developed in recent decades.
Since 1999, the first meteorological equipments imported from finland in our country have gained a qualitative leap in the meteorological observation technology in our country, and since the meteorological departments in our country have built and the automatic meteorological stations in each area have built successively, the ground observation system and various automatic meteorological stations in our country have built 16000 sets of automatic meteorological stations with various functions and different purposes. The automatic observation is used and researched comprehensively, which means that the main body of the meteorological system in China is changed, and the technology and data are greatly improved.
Wind measuring instruments occupy an indispensable position in all meteorological departments in China, however, for most meteorological units, the wind measuring instruments are still selected from traditional mechanical rotary wind measuring sensors, and the sensors are wind cup wind speed sensors and single wing wind speed sensors which are common in our daily life, so that the wind speed and the wind direction are measured. These conventional anemometry sensors are capable of acquiring the required data, but due to the mechanical construction, rotational inertia is unavoidable in these anemometry instruments. The detection of the anemometric data therefore loses a instantaneously changing one of the wind speed values. This causes a great difficulty in the study and detection of wind speed, which is also a problem to be solved by the current method. When the traditional mechanical wind measuring instrument in the meteorological station carries out the wind measuring operation, because the operating characteristics and the measured data in the operation come from two different directions, the time factor and other factors are obviously different in the measured data. And due to the fact that a turbulence characteristic exists in wind speed measurement, the data obtained from a wind measuring instrument is increased in error. When the wind cup sensor and the single-wing wind speed sensor are started, the wind speed is different, and the measured data may be completely wrong. Due to these characteristics of the conventional mechanical rotary anemometry, many difficulties are brought to further research on the wind for aerospace, military, conductive trajectory and flight. Therefore, the research on the automatic wind measuring instrument with firm structure and high practicability is very important.
The wind measuring instrument based on the orthogonal wind measuring principle can get rid of the traditional trouble, and can accurately acquire wind speed and wind direction angle data in real time, because the wind measuring instrument uses two groups of silicon piezoresistive differential pressure sensors which are orthogonal to each other, and four wind measuring pipes are connected at the pressure measuring ports, the structure mode is more stable, and the wind measuring instrument gets rid of the traditional mechanical rotary sensor, so that errors caused by rotation inertia can be avoided, researchers can more accurately measure the wind speed in meteorological elements, the quality of meteorological information is improved, and great contribution is made to military and aerospace aspects.
The wind speed measuring meteorological device based on the orthogonal principle can effectively prevent liquid in a measuring environment from entering a wind measuring sensor carelessly by keeping pipe holes of a pressure sensing pipe horizontal, so that the sensor can not work normally and even damage the wind measuring sensor. Traditional tube hole causes liquid to get into the intake pipe along with the wind easily under strong wind torrential rain weather, if not in time clear up can cause the detection data distortion, serious sensor intake then can cause the sensor to damage.
On the other hand, the wind speed measuring meteorological device based on the orthogonal principle needs to ensure that 4 orthogonal wind ports (south-east-west-north) are horizontal, otherwise the measured wind speed precision is reduced, and after the equipment is installed, if the meteorological device is inclined under the action of external force, the measured data of the meteorological device is seriously distorted.
