[0031] see figure 1 , this embodiment provides a class board system 10, the class board system 10 includes a grid supply device 100, at least one grid integrated line 200 and at least one electronic class board 300, the grid supply device 100 passes through at least one grid integrated line 200 Connect with at least one electronic shift sign 300 . One end of each integrated grid line 200 is connected to the grid supply device 100 , and the other end is connected to an electronic board 300 . The total number of grid integrated wires 200 may be equal to the number of electronic boards 300 . For example, when the total number of grid integrated lines 200 is 5, then the number of corresponding electronic shift boards 300 is 5. If it is necessary to increase the number of electronic shift boards 300, then correspondingly, it is also necessary to increase the number of grid integrated lines The corresponding root number of 200.
