LED (light-emitting diode) board control system based on DEVICENET bus

The invention discloses an LED (light-emitting diode) board control system based on a DEVICENET bus. The LED board control system based on the DEVICENET bus is characterized by comprising a 24-revolution 5V power module and interface, a microprocessor, an LED data buffer driver and interface, a DEVICENET protocol processing unit, a DC (direct current)/DC power and communication isolator and interface and a TTL (Transistor-Transistor Logic)-RS232 circuit and interface. The LED board control system based on the DEVICENET bus has the advantages of high speed, high stability, flexibility in application and low cost.
