Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] like figure 1 As shown, the present invention uses the LED module as the light source to display the image, and realizes the remote control of the local remote control, the RS485 remote communication, and the controller product of the voice broadcast multifunctional guide board.

[0026] The six groups of LED modules are controlled by the controller and driven by the LED drive circuit. The voice chip is controlled by the single-chip microcomputer to drive the speaker, and the pre-recorded voice is played according to different display images, and the playback volume is adjustable. The single-chip microcomputer controls the communication chip to realize the RS485 communication between the controller and the upper computer. On the same shielded twisted pair, the address of the controller can range from 1 to 254, the communication baud rate is 9.6kBPS, and the max...

Abstract

The invention relates to an LED guiding sign controller. The LED guiding sign controller consists of a power supply circuit, LED drive circuits, a communication circuit, an MCU control circuit, a loudspeaker drive circuit and an infrared receiving head circuit. The power supply circuit comprises a three-terminal regulator U7 and a DC-DC isolation module U6. The MCU control circuit comprises an external oscillating circuit, a storage circuit, a resetting circuit, a debugging circuit and a main control chip U1. The number of the LED drive circuits is six. The loudspeaker drive circuit comprises a loudspeaker drive chip U4. The infrared receiving head circuit comprises an HL terminal. The communication circuit comprises a communication chip U5. The LED guiding sign controller has a local remote controller remote-controlling function, an RS485 remote communication function and LED module driving and voice broadcasting functions and has the advantages of being high in working reliability, wide in selection range, long in service life, electromagnetic-radiation-resisting and the like.

Description
