Signal isolation converter

Abstract

The invention discloses a signal isolation converter, which is connected between a fan master control system and a wind speed and wind direction instrument, wherein the wind speed and wind direction instrument is used for collecting wind speed and wind direction signals flowing through a fan and transmitting the wind speed and wind direction signals to the signal isolation converter, and the fan master control system is used for analyzing effective wind speed and wind direction signals processed by the signal isolation converter and adjusting operation states of the fan according to the received wind speed and wind direction signals. The signal isolation converter comprises a main machine communication module, a controller, an auxiliary machine communication module, a multi-path switch, a power supply module, a wind speed and wind direction-I conversion module, a wind speed and wind direction-2DO conversion module and a wind speed and wind direction-CNT conversion module. The signal isolation converter can convert the wind speed and wind direction signals collected by the 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 system 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 isolation converter applied between wind speed and direction information acquisition equipment of a wind power generating set and a main control system of a wind turbine. 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 domestically-made wind speed and direction information collection equipment, such as wind speed and direction instrument, anemometer... Although the wind speed and d...

[0003] Some domestically-made wind speed and direction information collection equipment, such as wind speed and direction instrument, anemometer... Although the wind speed and direction collection equipment has greatly improved in terms of wind speed signal and wind direction signal collection technology, the wind speed and direction collection equipment and the main fan The communication between 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 another Wind speed and direction data in different data forms, which often causes obstacles between the main control system of the wind turbine and the wind speed and direction acquisition equipment; The main control system can only select a specific wind speed and direction acquisition device to match with the main control system of the wind turbine, so it is easy to cause difficulties in the selection of wind speed and direction acquisition equipment
