According to the wireless measurement device, a plurality of air speed measurement units and a plurality of signal isolation units are arranged inside a furnace of the power station boiler, and a data acquisition and packaging unit, a wireless transmitting unit and a wireless exchange unit are arranged outside the furnace. The plurality of air speed measurement units are respectively connected with the plurality of signal isolation units, the plurality of signal isolation units are connected with the data acquisition and packaging unit, and the data acquisition and packaging unit is connected with the wireless transmitting unit. The wireless transmitting unit forms a wireless air speed data transmission network with an external wireless receiving terminal through the wireless exchange unit. The wireless measurement device is applicable to in-situ measurement for the cold-state aerodynamic flow field of the power station boiler.

Description

technical field [0001] The invention relates to a measuring device for an aerodynamic flow field, which belongs to the field of aerodynamics. Background technique [0002] The purpose of measuring the cold aerodynamic flow field of the utility boiler is to obtain the characteristics of the cold aerodynamic flow field in the furnace under different working conditions, and then guide the manufacture, installation, hot operation and technical transformation of the utility boiler. [0003] The existing cold aerodynamic flow field measurement methods of power plant boilers mainly include streamer measurement method, optical measurement method of three-dimensional flow field and tracer measurement method: [0004] The streamer measurement method requires surveyors to use anemometers to measure the velocity field in the furnace, and to observe the airflow conditions at a specified section in the furnace by setting streamers. This requires surveyors to carry out measurement work in...
