Frequency modulation type wind speed control and display system and setting method thereof

Abstract

The invention discloses a frequency modulation type wind speed control and display system and a setting method of the frequency modulation type wind speed control and display system. The frequency modulation type wind speed control and display system comprises a central processing unit (1), wherein the video output end of the central processing unit (1) is connected with a displayer (2), the control input end of the central processing unit (1) is connected with a keyboard (3), the frequency conversion control end of the central processing unit (1) is connected with a frequency converter (4), and the frequency converter (4) is connected with a fan (5). The frequency modulation type wind speed control and display system is characterized in that the data end of the central processing unit (1) is connected with a memory (6), and a wind speed frequency comparison table is stored on the memory (6). The frequency modulation type wind speed control and display system has the remarkable advantages of being simple in structure, low in cost, capable of meeting the requirement for detection of and control over the wind speed of a plurality of any positions in a test chamber, good in flexibility, and capable of meeting the customized requirement of the wind speed detection requirement of the special position.

Description

technical field [0001] The invention belongs to temperature and humidity control test equipment, in particular to a frequency modulation wind speed control and display system and its setting method.

AI Technical Summary

Problems solved by technology

[0005] The disadvantages of the prior art are: in the traditional test box design, the standard of wind speed environment is avoided, and no wind speed sensor is installed at the detection point for detection

When the equipment adjusts the wind speed for different test samples, it needs to test and adjust the frequency converter multiple times to obtain the wind speed that meets the requirements of the test point. Such an operation is very complicated and has high requirements for operators.

If the wind speed sensor is installed at each detection point, it will be very difficult to implement. First, it will increase the cost of the equipment. More importantly, the installation of multiple sensors in different positions will inevitably affect the reliability of the test sample in the test chamber. Installation and fixing, so the existing technology cannot complete the wind speed detection and control of all sampling points in the test chamber
