Automatic weather stations are meteorological instruments used to measure temperature, humidity, air pressure, wind speed, wind direction, total radiation, rainfall, evaporation, soil temperature, and soil moisture in nature. They are widely used in meteorology, oceans, environment, airports, and ports. Industry, agriculture, forestry and transportation. The modular design has the characteristics of stable performance, simple installation, free debugging, and ready-to-use. As a professional instrument, for non-meteorological departments in the selection, procurement should first read this article, according to their own characteristics to select the appropriate program.
First, the basic configuration A set of automatic weather stations should at least be meteorological data collection instrument, computer software, various types of sensors, the data can be saved in the meteorological acquisition display, can also be saved on the computer, display, curve, statistics, print.
The automatic weather station of our company is designed in a modular way. The user can freely select and match various sensors. At least one sensor can be selected and up to 13 sensors can be selected (one or more sensors of the same type can be selected).
More typical combinations are:
One element of automatic weather station ---- rainfall, that is, automatic rain gauge;
Two-element automatic weather station ---- wind speed, wind direction, ie wind speed and direction recorder;
Two-element automatic weather station ---- soil temperature, soil moisture, soil temperature and humidity recorder;
Four-element automatic weather station ---- temperature, air humidity, wind speed, wind direction;
Five elements of automatic weather stations ---- temperature, humidity, pressure, wind speed, wind direction, that is, the campus weather station;
Seven elements of automatic weather station ---- temperature, humidity, pressure, wind speed, direction, rainfall, evaporation;
Seven elements of automatic weather stations ---- temperature, humidity, total radiation, rainfall, evaporation, soil temperature, soil moisture, that is, agricultural weather stations;
Ten elements of automatic weather station ---- temperature, humidity, pressure, total radiation, wind speed, wind direction, rainfall, evaporation, soil temperature, soil moisture, automatic weather station.
Second, the relevant supporting temperature, humidity, pressure sensor should be placed in a light louver box;
Wind speed, wind direction sensor optional supporting portable bracket (2m);
The collector can be installed indoors. If the sensor is more than ten meters away from the room, a stainless steel protection box should be installed to install the collector.
Third, data communication The data communication mentioned here, refers to the data acquisition instrument and the computer this communication.
a. The distance between the data acquisition instrument and the computer is within 20 meters. It can be directly connected with RS232 cable.
b. The distance between the collector and the computer is between 20 meters and 1000 meters. It can be equipped with a pair of RS485 converters and adopts RS485 communication.
c. The distance between the data acquisition instrument and the computer is within 3000 meters. There is no major obstacle in the middle. It can be equipped with a pair of radio stations and adopt wireless communication.
d, the collector and the computer are far away from each other, and GPRS wireless communication is available. As long as there is a GPRS signal of the mobile communication service provider, a certain fee will be generated during the communication, which will be charged by the mobile communication service provider;
