Control system for dynamic locking test of seat slide rail

Abstract

The invention discloses a control system for a seat slide rail dynamic locking test, and the system comprises a servo module which is used for pushing a seat slide rail and a load to move at a set speed, and carrying out the expected force loading after the dynamic locking; the motion control module drives the servo module; the strain type force sensor module is used for converting and feeding back expected force; the pull rope type displacement sensor module is used for tracking and feeding back the position of the seat slide rail; the data acquisition module is used for performing high-speed acquisition on data of the sensor module; and the software module comprises an embedded program based on a P-type iterative learning algorithm. And the control system comprises a processor embedded with a real-time operating system and a host. The control system for the seat slide rail dynamic locking test can be directly applied to multi-specification seat slide rail, variable load and dynamic locking test, realizes self-learning and online control, improves data dynamic response, and is high in economic benefit.

Description

technical field [0001] The invention relates to a control system for a dynamic locking test of a seat slide rail, and relates to the technical field of the dynamic locking test of a seat slide rail. Background technique [0002] With the rapid development of the automobile market in recent years, customers pay more attention to the comfort, durability and environmental protection of automobiles, and the safety, comfort, lightness and other related technologies of automobile seats have been continuously developed. The requirements for seats that are in direct contact with the human body are very detailed. In recent years, major domestic and international automobile manufacturers have introduced their own detailed car seat test standards, and the national automotive industry standards and European and American standards are also constantly updated. [0003] At present, the control system of traditional equipment is basically based on PLC or PC platform, and there are certain d...

AI Technical Summary

Problems solved by technology

Due to the low acquisition rate of analog quantity acquisition, the PLC platform has poor dynamic response to data, low data processing capability and small data storage space, and the user interface is not as rich and friendly as PC

The PC platform runs a multi-task time-sharing operating system, which has the characteristics of multi-path and interactivity, which is not as good as the high reliability and real-time performance of the real-time operating system.

[0004] In addition, in terms of motion drive and force loading, traditional equipment used to be more inclined to cylinder implementation. Although the structure and control are simple, it is easily affected by the stability of the air source and the high and low temperature alternating environment of the seat test, so there is control accuracy.
