Hardware on-ring intelligent carriage teaching scientific research experiment flatform

Abstract

The invention discloses a teaching scientific-research experiment platform for a hardware-in-the-loop intelligent track and belongs to the technical field of mechanical electrical integration . In the invention, a supervisory computer software module in a computer is used for analyzing and processing status information of the track and gives control instructions to the track. The computer exchanges data with a communication system through a computer communication interface. The supervisory computer software module analyzes and extracts the status information of the track after receiving the status data frames of the car, and synthesizes the control instructions to form control instruction data frames before the supervisory software module dispatches the control instruction data frames. An intelligent track system carries various sensors and motion execution units of a track model. The information acquired by the sensors is synthesized into status data frames of the track and dispatches the status data frames to the communication system. After the intelligent track system receives and analyzes the control instruction data frames from the communication system, the smart track system extracts effective control instruction information, and outputs the control signals of a motor and a control actuator to control the motor and the control acutator. The invention can be used for simulation and demonstration of scientific research experiments.

Description

technical field [0001] The invention relates to an experimental platform in the technical field of electromechanical integration, in particular to a hardware-in-the-loop intelligent car teaching and scientific research experiment platform. Background technique [0002] In the undergraduate experimental teaching of majors and disciplines such as control, pattern recognition, sensors, electronics, electricity, single-chip microcomputers, communications and mechanics, each major and course has an independent experimental platform, and its experimental equipment and content are independent of each other. There is no correlation, resulting in high cost of experimental equipment, and it is time-consuming and laborious for students to learn, and the experimental results are not ideal. If we can design a general-purpose multi-functional comprehensive experimental platform involving the above-mentioned many subjects, the platform not only integrates various technologies and professio...

Problems solved by technology

However, on the one hand, due to the knowledge involved in microcontroller programming, electronic circuit design, sensor technology, etc., the development cycle is long and difficult, and it is not suitable for teaching; on the other hand, the processing speed and on-chip resources of the microcontroller are limited, which limits the application of complex algorithms.

To this end, Tsinghua University has developed the Plastid simulation system. Using this simulation system, the original design scheme can be repeatedly studied to obtain the optimal scheme, and then the actual vehicle design and the actual track experiment can be carried out, thereby reducing the development cost and time cost. Improve the efficiency of smart car development (Zhou Bin et al., Smart Car Simulation System Based on Virtual Instrument Technology, World of Electronic Products, Issue 02, 2006, P132-134), but the system is a pure software simulation, the dynamic model is relatively simple, and the animation effect It is not realistic enough, and its application is quite limited
