Technical Field

The invention relates to the technical field of medical display, in particular to a piece reading gravity center light wireless distributed self-correcting system.

Background

In the field of film reading centers, the light design strictly follows IEC and German DIN6868-157 illumination standards, and the optimal illumination of the film reading environment of a doctor is kept at 50-100 lux, so that the accuracy of the diagnosis of the doctor in the film reading process is ensured, and doctor-patient disputes caused by misdiagnosis or missed diagnosis are avoided. In order to solve the problem, the patent number is "CN 201810062979", the patent name is that an intelligent film reading room system based on wireless QA control provides a system that uses a light intensity sensor to dynamically monitor the brightness of light in a film reading room in real time, and then sends the monitored light intensity data value (for example, 150lux) to a centralized management system, and the centralized management system controls the light system to reduce the brightness value, so that the monitoring value of the light intensity sensor is 100 lux. However, the solution has a certain disadvantage that since the doctor mainly and mainly reads the film at the film reading station and reads the film and writes the report by using a professional medical display, the indoor illumination can only be monitored by a single light illumination sensor, and the indoor light illumination is not uniformly distributed in other areas such as a window area due to the influence of external ambient light, so that the single light illumination sensor is used for monitoring, which is a rough method that the optimal illumination of the light in the actual film reading area of the doctor station can not be completely guaranteed to be 100 lux.
