Wrist monitoring system with multiple photoelectric sensor modules

The invention discloses a wrist monitoring system with multiple photoelectric sensor modules. The collection quality of the monitoring system is judged by using the theory that the correlation among photoelectric volume pulse wave tracing signals collected at the same area is high and by calculating the correlation of two photoelectric volume pulse wave tracing signals at the same area. The difference brought by the measuring result and the practical parameters caused by poor collection quality is avoided, and the measurement quality is improved.
