Research On Upper Body Strength Training Monitoring System

Upper limb strength training device is an auxiliary device for those with weak upper limbs.At present,the strength training equipment on the market in China is still based on pure mechanical type,and the level of intellectual control is not high,while the safety factor is low.How to carry out automatic control and transformation of training equipment,so that training equipment from fully autonomous to intelligent aided development has become the hot spot of the current chase.The upper body strength training supervision system designed by this paper is used as the Featured product of the ORIENT series of pneumatic training equipment.The control system is mainly controlled from the secondary level.Including training equipment embedded control,and training data management system in two parts.(1)Training supervision system design plan.The PC-based service host is used as the main unit to issue different task instructions to the training equipment,and uses RFID wireless communication to recover specific training data to form an interactive training system.At the same time,it manages large-scale customer data reasonably and builds it into one platform.The service host corresponds to the "one-to-many" management mode of multiple training devices.(2)Training equipment embedded control.The system takes the stm32 as the main control and realizes the three types of training requirements of free training,target training and test training.In terms of pneumatic control,the closed-loop control is realized by the compound control-driven proportional solenoid valve,and the PID control is supplemented by the anti-hysteresis loop feed-forward compensation to accurately control the pneumatic load.At the same time,the displacement sensor is used to collect the completeness of the action.The RFID wireless communication protocol is used to store the data in the ID card.The external display screen on the device can display the training data synchronously.(3)Training data management system.Data management system is designed and implemented on the PC side with Visual Studio 2010.It manages customer information information through interactive operations,completes information exchange via RFID radio frequency,dispatches task commands in different modes,and realizes data interaction with embedded control systems,and data is exchanged.Drawn into an exercise curve.After real machine testing,the upper limb strength training supervision system has realized three kinds of high-degree-of-freedom training mode training,and data exchange with the management system is normal.The whole training system basically satisfies the current market demand,has considerable economic value and broad development space.
