And a lens is arranged above the image sensor, an optical image focused by the lens is converted into an electric signal and transmitted to the MCU, and the MCU encodes the received electric signal and transmits the encoded electric signal to the mainboard BMC through the USB interface. FLASH is used for storing MCU firmware.
The mainboard BMC receives the image acquisition data, stores the image acquisition data into a local TF (T-Flash) card, and synchronously uploads the image acquisition data to a web server through an RJ45 interface for online display. A photosensitive IC device is added outside the BMC to sense the light intensity inside the case, and whether a light supplement LED is turned on or not is judged according to the light intensity so as to guarantee the definition of collected images.

For clearly explaining the implementation of the design method, the implementation steps are described with reference to fig. 1 and 2. The method comprises the following specific steps:
1) the image sensor and the lens are selected according to the requirements of the practical application scene on image resolution, monitoring position, angle and the like, and a 1080P high-definition wide-angle lens is preferably selected for ensuring the monitoring effect. The LED installation position needs to be close to the lens so as to achieve a good light compensation effect, and a white light LED device is preferably selected, so that a color image can be obtained when the illumination intensity is weak, and the color image is convenient to view.

Considering that the possibility of change of the chassis environment along with time exists, the BMC adopts a polling read photosensitive IC scheme, and the interval time is defaulted to 1 s.
4) In order to reduce the board power consumption, the BMC may start the image capturing function only under a specific condition, where the triggering condition includes, but is not limited to, the following conditions: the case is opened and the BMC is controlled manually under a web interface. The state switch at the cover is connected with the BMC, so that the BMC can detect the opening action of the chassis.
