The exploitation of Cortex processor and design, not only have ARM embedded technology stability is good, powerful, good in anti-interference performance, after
The advantages that phase scalability is good, remote maintenance facilitates, while also having the advantage of the low-power consumption of MSP430 single-chip microcontroller, low cost.
Present embodiment uses ultrasonic wind speed and direction intelligent sensing acquisition technique: ultrasonic wave refers to that frequency is greater than
The sound wave of 20KHz, ultrasonic wave have good directionality, penetration capacity relatively strong, and the characteristic with common sound wave can produce
Hair tonic penetrates, interferes, being superimposed and covibration.People find that very early the aerial spread speed of sound wave by air flowing (and
Wind) influence, propose inversely derived using the variation in measurement sound wave propagation time between the two o'clock of known distance thus
The method of point-to-point transmission wind speed out, as shown in Fig. 2, ultrasonic wind speed and direction measuring principle.One group of ultrasonic wave is emitted by transmitting probe
Pulse reaches receiving transducer, from emit fierce pulse play receive first pulse to ultrasonic propagation time be t1=L/
(v0 ± v), acoustic wave propagation velocity when wherein v0 is calm, v is wind speed, and L is propagation distance, when direction and ultrasonic wave propagation side
To it is consistent when be positive, otherwise be negative.But v0 will receive the influence of the environment such as temperature, humidity, air pressure, Media density, change meeting
Introduce biggish measuring wind speed error.The method that the project uses two -way difference measurement, while measuring in two relative directions
The variation in propagation time carrys out the error of the influences such as compensation temperature, humidity, air pressure, Media density.
Using two pairs of mutually orthogonal transmitting-receiving integrated ultrasonic sensor probes, and it is mounted in same level, phase
Pair two ultrasonic sensors successively issue measurement pulse, pulse and calculated by being received to relative probe, it can be deduced that the two
Propagation time and speed, the wind speed and direction of horizontal plane can be obtained finally by orthogonal operations.
Present embodiment uses the piezoelectric type rain collection technology of impact principle: continuing precipitation and heavy rain is to form mud-rock flow
One of an important factor for.Effective low monitoring heavy rain and lasting precipitation, and carry out forecast prediction work, it is prevention mud-stone flow disaster
One of important engineering measure.It common are hydrocone type and two kinds of tipping bucket type rain gage bucket, but two kinds of sensor all volumes are big, cannot survey
Snow, sleet, hail are measured, and water filling port is easy to be blocked by leaf, silt and be unable to measure rainfall.There have been impact, thunder in foreign countries
The rainfall measurements technology such as reach, be infrared, and China there is no such product.
Present embodiment proposed adoption shock measurement principle calculates single raindrop weight, and then calculates rainfall
Amount.Effect of the raindrop in descent by raindrop weight and air drag, speed is constant speed when reaching ground, according to
P=mv, measurement impact can find out raindrop weight, and then obtain continuing rainfall.

To bear 44V forward voltage and 20V backward voltage, thus device reversal connection will not damage.Using reliable.It only needs direct current
Source can work, moreover, without carrying out linearity correction, so interface is also very simple using also very convenient.It is exported as electric current
One feature of type sensor is compared with voltage output type, it has very strong external interference resistance.The measurement of AD590 is believed
It number can the over one hundred rice of teletransmission.
Present embodiment develops humidity sensor using HS1100/HS1101 chip.HS1100/HS1101 capacitor
Sensor is equivalent to a capacitor element in circuit composition, and capacitance increases with the increase of surveyed air humidity.It is not required to
The absolute interchangeability of calibration, high reliability and long-time stability, fast-response time, relative humidity is within the scope of 1%---100%RH；
Capacitance changes to 200pF by 16pF, and error is not more than ± 2%RH；Response time is less than 5S；Temperature coefficient is 0.04 pF/ DEG C.
It can be seen that precision is higher.
Present embodiment designs optical sensor using GY-30 optical sensor, is set using GY-30 optical sensor
Optical sensor is counted, for measuring required illuminance.GY-30 optical sensor uses the original-pack BH1750FVI chip of ROHM, light
Illumination range is 0-65535 lx, its included built-in 16bitAD converter can directly export number, omit complicated calculating,
Calibration is omitted.As mainstream optical sensor, GY-30, which has, does not distinguish environment light source, and the light splitting close to visual sensitivity is special
Property, extensive brightness is reached the high-precision of 1 lux, advantage small in size and at low cost, and its power supply be 3~
5V。
Embodiment 1: as global warming aggravates in recent years, the extreme meteorological and diastrous weather in China frequently occurs, gas
As environmental monitoring and construction have been a national grand strategies.The present invention uses integrated structure design, has at low cost, smart
Spend it is high, non-maintaining etc. a little, airport, wild nature reserve area, the multiple area of meteorological disaster, coastal/navigation, solar power generation,
There is important application in the fields such as overhead transmission line, have to the monitoring of realization China's gridding weather environment and construction system important
Social economic value.
In addition, the development of the present invention at home is completed and listing, to change tradition machinery formula meteorological sensor, reduce to dimension
The dependence of the imported products meteorological sensor such as Sa La, development of national native country digital intellectualization weather monitoring product also have important warp
Ji value.
