A Spread Spectrum Microwave Transmission System for Remote Meteorological Tower

Abstract

The invention discloses a spread spectrum microwave transmission system of a remote anemometer tower. The spread spectrum microwave transmission system of the remote anemometer tower comprises data collecting and transmitting equipment arranged on the remote anemometer tower and data receiving and monitoring equipment arranged on a local receiving station. The data collecting and transmitting equipment is connected with the data receiving and monitoring equipment in a wireless mode. The spread spectrum microwave transmission system of the remote anemometer tower can overcome the defects that dependence degree of communication signals is high, an applicable range is restrained and reliability is subject to the communication signals in the prior art and has the advantages of achieving a wide geographical selectable range and being not restrained by the communication signals.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a spread-frequency microwave transmission system for a remote wind measuring tower. Background technique [0002] At present, wind measuring towers are set up in areas with good wind resource conditions, and long-term observation and collection of wind speed and wind direction data measured at heights of 10m, 30m, 50m, and 70m on the wind measuring towers, to obtain changes in wind energy conditions in a region , and then determine the wind energy resources in the area based on this, and provide preliminary services for the construction of wind farms. [0003] For example, in the Chinese patent (application) with the patent (application) number 201220025872.X, a real-time wind resource network management system for wind power bases with tens of millions of kilowatts is provided. see figure 1 , the real-time wind resource network management system of the 10-million...

AI Technical Summary

Problems solved by technology

The method of manual data acquisition obviously cannot meet the needs of real-time monitoring of wind resources and ultra-short-term forecasting of wind power

[0018] Due to the coverage limitation of mobile operators' base stations, there is no GPRS and GSM signal service in remote Gobi, grasslands and other sparsely populated areas, making it impossible to build real-time wind measuring towers in the above-mentioned areas to monitor real-time wind conditions in these uninhabited areas

However, most of my country's wind power bases are located in the north, and some areas are deserts, Gobi, grasslands and forests with few people. Existing technologies cannot solve this situation.

[0019] In the process of realizing the present invention, the inventor found that there are at least defects in the prior art, such as high dependence on communication signals, limited scope of application, and reliability dependence on communication signals.
