The present invention relates to a monitoring system, and particularly to a dynamic monitoring system with radio-frequency identification.
Dynamic monitoring of personnel has always been an essential issue in today's society. In companies or factories, it is often necessary to control and monitor personnel's entry and exit. In stations, department stores or gatherings, control and monitor of personnel are also crucial tasks.
At present, most monitoring and management systems utilize human power to identify or measure body temperature, and specific personnel are required to identify or measure body temperature of passing personnel, or passing personnel may operate a clock in a device to clock in by themselves. The existing monitoring system is not only cumbersome and slow, but also requires additional manpower. When personnel are queuing up to clock in, they also increase the risk of contact, which may cause the spread of diseases. Therefore, how to improve the efficiency and accuracy of the monitoring system is a matter of urgency, and how to establish an effective monitoring system is the focus of attention of relevant personnel in the field.
