Abstract

The invention provides a device for detecting wind pressure, which comprises a temperature collecting module (10), a wind turbine module (20), an electric current detecting module (30), a control module (40) and a storage module (50). The invention provides a method for detecting the wind pressure, which comprises the steps of: detecting the environmental temperature of the wind pressure detecting device, the current rotating speed of a wind turbine and the electric current of the wind turbine; carrying out temperature compensation on the electric current of the wind turbine according to the environmental temperature; and judging whether current external wind pressure generates wind obstruction according to the value of the wind turbine electric current subjected to the temperature compensation, a prestored value of the wind turbine electric current being subjected to the temperature compensation and corresponding to the current rotating speed of the wind turbine and rated electric current capacity quantity of the wind pressure corresponding to the current rotating speed of the wind turbine. By means of the device and method for detecting wind pressure, disclosed by the invention, wind pressure detection errors brought by the influence of the environmental temperature on the electric current of the wind turbine can be reduced.

Description

technical field [0001] The invention relates to a wind pressure detection device and a detection method, in particular to a wind pressure detection device and a detection method applied to gas water heaters or heating furnaces. Background technique [0002] The detection of external wind pressure is a necessary process for gas water heaters and heating furnaces, which will directly relate to whether the combustion of gas water heaters and heating furnaces is normal and whether the carbon monoxide exceeds the standard. At present, gas water heaters and heating furnaces usually use wind pressure switches, that is, use the pressure of gas to push the micro switch to realize the wind pressure detection method of detecting the pressure of the combustion chamber: when the fan is not working, the pressure on both sides of the differential pressure plate is in a balanced state, and the spring pushes Under the action of the spring force, the rod presses the micro switch to make it in...
