Problems solved by technology
However, the existing method of writing characteristic values to LED display transmission devices is relatively cumbersome, and additional input ports and output ports need to be added to each LED display transmission device, so that each LED display transmission device forms a series connection, and each LED display transmission device is connected in series. The display transmission device writes characteristic values, adding input ports and output ports to the LED display transmission device will increase the production time of the LED display transmission device, and also increase the complexity of the connection between the various LED display transmission devices in the multi-stage transmission system More seriously, after the input and output ports are added to the LED display transmission device, once these two ports fail, the reliability of the LED display transmission device will be seriously affected

The invention relates to an LED display transmission system. The system is characterized in that a controller sends a control voltage to each LED display transmission device through a first switch when the first switch and a second switch are in a closed state, so that each LED display transmission device determines a corresponding serial number value according to the received control voltage; when the first switch is in a closed state and the second switch is in an open state, the controller sends control data to each LED display transmission device through the first switch, and when each LED display transmission device receives the control data, sub-data corresponding to the corresponding serial number value of each LED display transmission device in the control data are sent to the controller through the controller; the characteristic values of the LED display transmission devices are stored, the hardware structure of the LED display transmission devices does not need to be changed, the production time consumption of the LED display transmission devices is reduced, and the production cost of the LED display transmission devices is saved.
Description
technical field [0001] The present application relates to the technical field of LED display transmission, in particular to an LED display transmission system. Background technique [0002] As LED displays are widely used in leisure and cultural squares, bustling business centers, commercial streets, railway stations, subways, shopping malls, and other places, due to the diversity and complexity of their application fields, the stability, reliability, and Fluency also puts forward higher requirements. [0003] In the existing LED display transmission technology field, in order to improve the reliability of signal transmission, the multi-level transmission system formed by multiple LED display transmission devices will make the LED display transmission devices adopt parallel connection instead of serial connection, so There is no mutual influence, but using the parallel connection mode requires writing different characteristic values into each LED display transmission devi...
