Portable multi-function turntable test system based on wireless transmission

Abstract

The invention discloses a portable multi-function turntable test system based on wireless transmission, which mainly solves the problems of high cost, complicated structure and poor test data stability of the traditional slip ring system. The system comprises an upper computer (13), a controller (14), a drive motor (4), a turntable (15) and a data transmission system, wherein the data transmission system comprises a wireless data acquisition and transmitting module (10) and a wireless data receiving and processing module (12), the wireless data acquisition and transmitting module (10) is used for acquiring and processing the test data of the turntable and transmitting the test data in a wireless mode; and the wireless data receiving and processing module (12) is used for receiving the test data transmitted by the wireless data acquisition and transmitting module (10), carrying out level conversion on the test data and then transmitting to the upper computer (13) for processing, displaying and storing. The system has the advantages of reliable test data, simple structure, light weight and convenient maintenance, and can be used for the performance and reliability tests of various devices, especially various sensors.

Description

technical field [0001] The invention belongs to the technical field of testing, and relates to a turntable testing system, which is mainly used for working site environment simulation and testing of product performance and reliability. Background technique [0002] As a kind of simulation equipment for on-site environment simulation and product performance testing, the turntable has important application value and broad application prospects in the fields of aerospace, automobile manufacturing and sensor technology. Traditional industrial turntable structures such as figure 1 As shown, it mainly includes a load platform 1, a support structure 2, a drive motor 4 and a slip ring system. The test object is installed on the load platform 1 during operation, and the drive motor 4 drives the load platform 1 through the drive shaft 3 to perform a prescribed rotational motion. The signal is output by the lead wire 7 through the slip ring system. The slip ring system includes the sl...

AI Technical Summary

Problems solved by technology

[0003] 1. The structure is complex, the volume is huge, the price is expensive, and there are great restrictions on the use occasions;

[0004] 2. Slip rings are expensive and easy to wear, and the testing and maintenance costs are expensive;

[0005] 3. The slip ring servo system has an inevitable interference effect on the smooth operation of the turntable spindle, and the wear of the slip ring itself will also lead to a decline in the performance of the turntable
