Problems solved by technology

1. The mechanical type is mainly the wind cup type and the wind wheel type. Since the runner is a movable component, factors such as mechanical friction, sediment and dust accumulation make the reliability of the instrument not high and the error is large; 2. The dynamic pressure type is based on the complete Hosting is the main method, and the error is relatively large when measuring small wind speeds; 3. Ultrasonic anemometers have high precision, but they are expensive; 4. Thermal anemometers mainly include hot-wire types, which are widely used in the field of gas detection, but are expensive
Therefore, the application is limited by the problem of

Abstract

A wireless meteorological data monitoring device for a wind farm relates to a meteorological data monitoring device, which solves the problems of low reliability, large error and high price of the monitoring device. The data collected and output by the data acquisition module of the present invention is transmitted to the data processing module through the ZigBee wireless transmission module. The advantages of the present invention are that the ultra-low power consumption MCU is used to make the power consumption of the device very low; the use of a hot film wind sensor makes the device high in precision, low in cost, good in durability, strong in adapting to the environment, and wide in application temperature range; adopting Zigbee wireless The transmission module solves the problem of wired transmission of the device, reduces the size and quality of the device, and saves the cost of wind resource assessment and manpower input in the early stage.

Description

technical field [0001] The invention relates to a meteorological data monitoring device. In particular, the invention relates to a wireless meteorological data monitoring device for a wind farm. Background technique [0002] At present, the existing wind farm meteorological monitoring devices are divided into four types according to different working principles: mechanical type, dynamic pressure type, ultrasonic type and thermal type. 1. The mechanical type is mainly the wind cup type and the wind wheel type. Since the runner is a movable component, factors such as mechanical friction, sediment and dust accumulation make the reliability of the instrument not high and the error is large; 2. The dynamic pressure type is based on the complete Hosting is the main method, and the error is relatively large when measuring small wind speeds; 3. Ultrasonic anemometers have high precision, but they are expensive; 4. Thermal anemometers mainly include hot-wire types, which are widely ...
