The application discloses a real-time analysis system and method for muscle activity based on electromyographic signals, and relates to the technical field of electromyographic signals, and comprises the following steps: calling signal acquisition records of user project training, extracting corresponding sampling frequencies, and obtaining target sampling frequencies; collecting electromyographic data of muscle contraction completed by the user; decomposing the training project into a plurality of training actions, obtaining a reference vector set of each limb, and obtaining an effective time period of each training action; dividing the effective time period into a plurality of time windows, establishing a time domain function corresponding to the effective time period, and obtaining a target time length of each training action; acquiring a training action at the current training time, evaluating abnormal conditions of the training action, and giving early warning and prompt to relevant instructors. The application analyzes historical signal acquisition records in combination with multi-dimensional characteristics, monitors abnormal behaviors in the project training process in real time, gives early warning and prompt to instructors in a timely manner, and is helpful to reduce the risk of muscle injury of the user.

The invention is suitable for the technical field of meat processing, and provides an intelligent generation method and system for a slitting path of meat with bones, and the method comprises the steps: collecting three-dimensional point cloud, component distribution and meat block state data of the surface of meat with bones; constructing a three-dimensional skeleton model and a muscle contraction model; determining an obstacle avoidance area based on the skeleton model, and planning an initial slitting path in combination with the muscle fiber direction; and simulating a deformation process after cutting by using a muscle contraction model, adjusting path parameters according to expected displacement and shape change, and generating a final target slitting path. According to the method, meat block deformation caused by cutting can be accurately predicted and compensated, the slitting precision and finished product consistency are improved, and the method is suitable for an automatic meat processing system.
