Embodiment
[0039] Refer to the following figure 1 , Figure 4 The present embodiment is described further:
[0040] Such as figure 1 , 4 As shown, the internal control LED digital tube system includes a computer controller M1, a data converter M2 and at least one internal control unit M3, and each internal control unit M3 is connected according to the data flow direction to form an LED dot matrix. The function of the computer controller M1 is: according to the type, quantity, arrangement position and connection rules of the internal control unit product M3 used in the actual project of the customer, generate the corresponding LED mapping dot matrix data, and then according to the demonstration effect required by the customer and the aforementioned The LED maps the dot matrix data to generate the demonstration control data of each digital tube, and finally transmits it to each internal control unit M3, and each internal control unit M3 receives and saves the demonstration control data ...

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).
Description
technical field [0001] The invention belongs to the technical field of LED landscape and decorative lighting applications, and in particular relates to an internal control LED digital tube system and a control method thereof. Background technique [0002] Common LED landscape decorative lights include guardrail tubes, soft light strips, pixel lights, wall washers, etc., which are widely used in landscape lighting and building decoration. Colored LED guardrail tubes, also known as LED digital tubes, have been widely used in various occasions such as building outlines, bridge road decoration lighting, RGB guardrail tube light screens, and full-color digital signboards. Existing LED digital tubes mainly adopt external control mode, and a small part adopt internal control mode. [0003] Externally controlled LED digital tubes need to be connected to an expensive external controller during demonstration work, such as Chinese patent No. 200410032618.6, named: a LED guardrail tube...
