Design of the control system for the wheelchair's test stand.

In the article, the construction of the control system of the test stand intended for testing wheelchairs is described. The device allows for controlling drive systems (asynchronous motors) through inverters, as well as reading data from torque meters and force sensors in order to determine the centre of gravity of the standing wheelchair. It was built based on a PLC controller with input-output modules. The whole works under the control of the real-time operating system, which enables synchronous recording of individual data with a constant time determinism. Selected measurement results are included in the experimental part. The data was also displayed on a specially prepared visualization. An Ethernet interface was used for communication. In the experimental part, selected measurement results are presented in the form of graphs. These results can be used to verify simulation models, as well as to obtain information about the biomechanics of the movement of people with reduced mobility, who use wheelchairs on a daily basis.
