Example Embodiment
[0043] Example one:
[0044] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the present invention provides an analog SD card reading and writing system, which includes an SD card housing 3 for plugging into the SD card slot 41 of the lower computer 4. There are several plug-in guides on the SD card housing 3 Pin 31 matches SD card slot 41;
[0045] The data harness 2 includes several data lines. One end of the several data lines is electrically connected to the plug pins 31 on the SD card housing 3, and the other end of the several data lines is connected to the I / O port of the smart receiver 1;
[0046] Smart receiver 1, save the animation data downloaded from the cloud or centralized control terminal in its own SD card or Flash memory or solid-state hard drive. By receiving remote playback instructions, the smart receiver 1 can send the corresponding data through the data cable 2 and SD card shell 3 are sent to the lower computer 4 for playback.

Example Embodiment
[0061] Embodiment two:
[0062] Such as Picture 9 As shown, the present invention provides an urban lighting engineering control system, including several decorative lamps installed on the outer walls of several buildings in the city and several independent lamp controllers that control the lighting of these lamps to form a certain image or text. A lamp controller is equipped with an SD card reading and writing device, that is, a lower computer. The lower computer lights up a specific image or text on the outer wall of the building by reading and writing stored data. It is characterized in that the lower computer controlled by each lamp is connected and implemented The analog SD card reading and writing system described in Example 1.
