Mini-fan performance test system based on human-computer interaction interface

Abstract

The invention discloses a mini-fan performance test system based on a human-computer interaction interface. The human-computer control and display module of the test system is connected with a drive motor module, a performance parameter data acquisition module and a pulling motor module respectively; the human-computer control and display module contains a communication interface, a controller and the human-computer interaction interface; and the human-computer control and display module obtains the instructions of the user through the human-computer interaction interface, then the instructions are processed by the controller to control the rotation speed of the drive motor module and the frequency of the pulling motor module through the communication interface, and the human-computer control and display module exchanges data with the performance parameter data acquisition module to obtain the required information. The test system of the invention is suitable for the performance testsof various mini-fans; the main performance parameters to be tested contain static pressure, flow, rotation speed, torque, wind speed and the like. The invention provides real data for the high-performance design of the mini-fan and plays an important role in the optimization of the structure and parameters of the mini-fan.

Description

technical field [0001] The invention discloses a micro-fan performance testing system based on a man-machine interaction interface. Background technique [0002] Fans are widely used in various sectors of the national economy. In order to make the fan operate in the high-performance area frequently, it is necessary to refer to the fan performance curve to select the best operating point of the fan. The fan performance test is a scientific, reasonable and objective method to evaluate its performance index. The parameters to be tested include flow, wind pressure, torque, speed, wind speed and environmental parameters such as air temperature and air pressure. At present, the fan performance testing method in my country is mainly based on the traditional conventional method, mainly by manually reading the meter for the test, which is not only time-consuming and laborious, but also prone to various errors in the manual reading and recording process, and the accuracy of the test ...

Problems solved by technology

For example, Xi'an Jiaotong University has developed an automatic test device for duct-type fan performance tests, which has promoted the application of automatic test technology in the field of fans, but it is only suitable for performance tests of large and medium-sized air-conditioning fans, and cannot perform performance tests on micro-fans. The micro-fan performance test device with machine-interaction interface can solve the above problems very well.
