This invention discloses a LED lattice display system of the cage operation information, incl. leakage cable wireless communication system, principal computer with cage operation information acquired, LED display module. The leakage cable wireless communication system includes the leakage communication base station, leakage cable, aerial, leakage communication mobile station. The LED display module includes communication control card, controller, LED lattice screen. The principal computer is communicated through the serial port with the leakage communication base station to send the acquired cage operation information to the base station, while the leakage communication mobile station receives through the aerial the information sent by the leakage cable from the leakage communication base station, which will conduct the pointtopoint communication with the LED display module communication control card to send the received information to the communication control card connected to the controller. The received information is sent to the controller which is to display the received cage operation information onto the LED lattice screen for timely reminding the operator.
