Small meteorological station automatic small meteorological station

  Introduction to small meteorological stations:
Small meteorological stations are used for all-weather on-site monitoring of more than ten meteorological elements such as wind speed, wind direction, rainfall, air temperature, air humidity, light intensity, soil temperature, soil humidity, evaporation and atmospheric pressure
It can be connected with the computer through the professional supporting data acquisition communication line to transmit the data to the meteorological database of the meteorological computer for statistical analysis and processing

Application fields:
It is widely used in meteorology and agriculture to detect the impact of meteorological changes on crops and scientifically manage farmland planting
Small meteorological stations are special equipment for Agricultural Bureau, Chinese Academy of Sciences, soil and fertilizer stations and colleges and universities, which are suitable for standard good fields and water-saving irrigation projects

characteristic:
1
Software meets GB“ Standard Specification for automatic weather station & rdquo; It is required that the meteorological station directly measure the real-time value of each meteorological element through the sensor

2
It has comprehensive functions and high data measurement accuracy, and can expand more than 20 meteorological data
The host core adopts high-performance microprocessor as the main control CPU
Large screen graphic LCD with Chinese character and graphic display function, one screen displays multi-channel meteorological data, which is convenient for on-site direct observation

3
The host has a large memory, which can store 10000 pieces of data, continuously store the whole point data for more than 6 months, convenient operation, real-time and reliable data, etc

4
The software is the management software of meteorological ecological environment monitoring system, with friendly interface and multiple communication modes, which can support concurrent communication of more than 100 monitoring stations;
5
It can run in the system environment above Windows XP, display all kinds of data in real time, update it every 10 seconds, automatically store the whole point data (the storage time can be set within 1 ~ 24 hours), connect with the printer and automatically print the stored data
The data storage format is excel standard format, which can generate data charts for other software calls

6
It has the function of saving data after power failure
The stored data will not be lost after power failure
When the AC power failure, it can be automatically powered by the rechargeable battery
It is energy-saving and environment-friendly design
The service time of the battery can work continuously for more than 48 hours after one charge
It is equipped with solar power supply system, which is used jointly by solar panel and battery pack
It can be used for field operation and is suitable for perennial use in areas without electricity

6
It provides wired transmission and wireless transmission
The wired transmission mode includes: wired connection with the PC of the monitoring center through the standard RS232 / RS485 / USB communication interface
The longest wired communication distance can reach 1000m, and the collected data can be transmitted in real time
The wireless transmission mode can be divided into three wireless transmission modes: short-distance wireless transmission, medium-distance wireless transmission and long-distance wireless transmission according to the communication distance
It can also realize the real-time monitoring of multiple stations by one center through wireless communication

(1) Short distance wireless transmission mode: advanced microwave RF communication transmission module is adopted, and the communication distance is within 0 ~ 300m
It is mainly suitable for data transmission in short distance such as campus and field area, without any communication cost

(2) Long distance wireless transmission mode: using GSM / GPRS network communication technology, combined with internet network communication protocol, equipped with wireless communication controller, the monitoring center can realize real-time monitoring of each station and remote collection of meteorological data of each monitoring station, which is not limited by distance and reliable data transmission
