Embodiment Construction

[0011] The present invention is described below in conjunction with accompanying drawing:

[0012] The present invention is in the casing 3 of wind sensor, and is positioned at the bearing 4 of sensor and arranges a heating wire 5, simultaneously on heating wire 5 or between heating wire 5 and bearing 4, a temperature sensor (not shown in the accompanying drawings) Draw temperature sensor), the wire of temperature sensor links to each other with temperature controller, and temperature sensor used in the present invention and temperature controller are the commodities sold on the existing market. Since the present invention will be set in the field for a long time, people may be required to carry out necessary maintenance or overhaul of the wind sensor under different circumstances. Considering the safety of personnel during maintenance, the present invention determines to use a temperature controller to control one whose primary is 220 volts. A very 36-volt transformer is the ...

Abstract

The invention relates to a device which can prevent glaze ice, rim and icing freezing injury from affecting normal work of or damaging a wind speed sensor or a wind sensor used in an automatic weather station. The device consists of a heating wire, a temperature sensor and a power supply, wherein the heating wire can be arranged in a shell of the wind sensor and can be arranged outside a sensor bearing; the temperature sensor can be arranged on the heating wire or can be arranged between the heating wire and the sensor bearing; the power supply is controlled by the temperature sensor, is used for supplying power to the heating wire and has a working voltage of 36 V; and the on-off temperature of the temperature sensor is set to be between 3 and 40 DEG C.

Description

technical field [0001] The invention relates to a method for controlling the temperature of the wind speed sensor or the wind direction sensor used by the automatic weather station installed in the field, so as to prevent the wind speed sensor or the wind direction sensor used by the automatic weather station from being unable to work normally due to freezing damage caused by rain, smog and rime, or being damaged. damage. Background technique [0002] Automatic weather stations have been installed and used in more than 2,000 meteorological stations and hundreds of thousands of regional meteorological observation stations across the country. At present, the wind sensors of domestic automatic weather stations mostly use three-cup wind speed sensors and long-arm single-leaf wind direction sensors. The wind speed sensors and wind direction sensors are collectively referred to as wind sensors. The wind speed is measured when the wind speed sensor is rotating, and the wind direct...
