The invention relates to the technical field of expressway display screens, in particular to a display screen internal monitoring system, which comprises a power supply part, a display screen and a mobile terminal. Specifically, the display screen comprises an outer frame body, a control panel, a display electric plate, and a temperature sensor, a humidity sensor, an infrared dust sensor, a displacement sensor and a first transceiver that are fixedly installed on the inner wall of the outer frame body, the power supply part is connected with the control panel through a wire, the mobile terminal is provided with a second transceiver, and the second transceiver is in signal connection with the first transceiver; According to the invention, the humidity inside the outer frame body is maintained within a normal parameter range, the situation that normal operation of other electrical devices and circuits is affected due to too large humidity is avoided, hot air and dust are exhausted in time, normal operation of other electrical devices is prevented from being affected by too high temperature and dust accumulation inside the outer frame body, and abnormal displacement of the control panel is prevented, therefore, the control panel is located at a normal working position, and normal operation of each electrical device is effectively maintained.

    本发明涉及高速公路显示屏技术领域,具体涉及一种显示屏内部监测系统,包括供电部、显示屏和移动终端,显示屏包括外架体、控制面板、显示电板、固定安装在外架体内壁的温度传感器、湿度传感器、红外灰尘传感器、位移传感器和一号收发器,供电部通过导线与控制面板连接,移动终端安装有二号收发器,二号收发器与一号收发器信号连接;本发明使外架体内部的湿度维持在正常的参数范围内,避免湿度过大而影响其他电性器件和线路的正常运转,及时排出热空气和灰尘,防止外架体内部温度过高和灰尘积聚而影响其他电性器件的正常运转,防止控制面板发生异常位移,使控制面板处在正常的工作位置上,有效维持各个电性器件正常运转。
