Internal control type LED (light-emitting diode) nixie tube system and control method thereof

The invention provides an internal control type LED (light-emitting diode) nixie tube system and a control method thereof; the internal control type LED (light-emitting diode) nixie tube system can be freely installed according to actual requirements during engineering construction without an external controller under the condition that a demonstrating control program of each nixie tube is not burned in advance before leaving factory, and the code of each nixie tube is identified in advance; a user can update the demonstrating contents of the nixie tubes at any time; when the system works, each nixie tube can be independent of the system or keep pace with the system; and during maintenance, the nixie tubes at different positions can be used interchangeably. The internal control type LED (light-emitting diode) nixie tube system comprises a computer controller, a data converter and more than one internal controls units, wherein the computer controller comprises an LED (light-emitting diode) mapping dot matrix data module and a demonstrating control data module; each internal control unit comprises more than one group of LED (light-emitting diode) luminous elements, an LED (light-emitting diode) driving unit, a microprogrammed control unit (MCU) and a storage; the LED (light-emitting diode) driving unit is used for driving the LED (light-emitting diode) luminous elements; the microprogrammed control unit (MCU) is used for controlling data communication and the luminescence of the LED (light-emitting diode) through the LED (light-emitting diode) driving unit; and the storage provides a demonstrating control identification signal to be received and read by the microprogrammed control unit (MCU).
