Signal processing output method of signal isolation converter

Abstract

The invention discloses a signal processing output method of a signal isolation converter. By using the method, wind speed and wind direction signals collected by a wind speed and wind direction instrument can be converted to various data forms, so that requirements of different fan master control systems for data forms can be met, and effective communication between the fan master control systems and the wind speed and wind direction instrument can be well achieved.

Description

technical field [0001] The invention relates to a signal isolation converter, in particular to a signal processing and output method of a signal isolation converter used between wind speed and direction information acquisition equipment of a wind power generating set and a main control system of a fan. Background technique [0002] In wind power generation technology, wind speed and direction information acquisition equipment is becoming more and more important as one of the important and key wind turbine components. How to accurately and effectively collect wind speed and wind direction signals and realize wind speed and wind direction information acquisition equipment and wind turbine main control The communication problem between systems is one of the main problems faced by most wind power technology enterprises at present. [0003] Some existing domestic wind speed and direction information collection equipment, such as wind speed and direction instrument, anemometer... ...

[0003] Some existing domestic wind speed and direction information acquisition equipment, such as wind speed and direction instrument, anemometer... Although the wind speed and direction information acquisition equipment has greatly improved in terms of wind speed signal and wind direction signal acquisition technology, but the wind speed and direction acquisition equipment and wind turbine The communication between the main control systems is still a big problem, and the following problems often occur: (1) The wind speed and direction acquisition equipment uses one data form to transmit the wind speed and direction data, while the main control system of the wind turbine can only accept other data. Wind speed and direction data in a data form, which often causes communication barriers between the main control system of the wind turbine and the wind speed and direction acquisition equipment; (2) The main control systems of wind turbines produced by different main control manufacturers of wind turbines receive wind speed and direction data in different forms, The main control system of the wind turbine can only choose a specific wind speed and direction acquisition device to match with the main control system of the wind turbine, thus easily causing difficulties in the selection of wind speed and direction information acquisition equipment
