Abstract

The invention discloses a coding tester controlling LEDs based on a DMX512 protocol. The coding tester includes a microcontroller module, a DMX512 transceiver module, a key module, a display module, and a power module. The DMX512 transceiver module, the key module, the display module and the power module are electrically connected with the microcontroller module. Bidirectional input is carried outbetween the DMX512 transceiver module and the microcontroller module. The key module inputs information to the microcontroller module in a one-way mode. The power module inputs information to the microcontroller module in a one-way mode. The microcontroller module inputs information to the display module in a one-way mode. The coding tester of the invention has a simple structure, and facilitatesengineering field test. The technical problem that manual address code setting through dialing is heavy in workload is solved. The technical defect of high error rate is avoided. Moreover, the codingtester with an internal power module is easy to carry.

Description

technical field [0001] The invention belongs to the technical field of information control, and in particular relates to a coding tester for controlling LEDs based on the DMX512 protocol. Background technique [0002] The lighting system based on the DMX512 control protocol for dimming control is called a digital lighting system. At present, all kinds of stage lighting equipment including computer lights, dimming controllers, consoles, color changers, electric booms and other stage lighting equipment have fully realized dimming due to their full support for the DMX512 protocol. The digitalization of control, and on this basis, gradually tends to be computerized and networked. When LED lamps are coded, each LED lamp is coded. Currently, the codes on the market are basically controlled by the DMX512 protocol. The output content of the DMX decoding program written by the single-chip microcomputer used by each user is the same, but The format of the address code for access inp...
