Description

Using NFC technology to realize the method of setting the channel or address of DMX and DALI devices

technical field

The invention relates to the field of lighting control, in particular to the technical field of using NFC technology to realize setting channels or addresses of DMX and DALI devices.

Background technique

The channel code or address code of DMX and DALI control equipment and controlled equipment is similar to their ID cards. In the prior art, the setting of the channel code or the address code of the DMX and DALI control equipment and the controlled equipment is relatively complicated. Some DMX devices use RDM technology to set the channel or address through the handheld device. The problem with this method is that the DMX device needs to be powered on, and the DMX device and the RDM handheld device need to be connected; DALI devices are currently generally controlled by DALI systems. To assign the address, there is also a circuit on the DALI device, and the address is set by pressing the button, but both methods must be powered on, and the line must be connected first to assign the address through the DALI control system; there is another method at present. A dial switch circuit is added to the DMX equipment and DALI equipment, and the channel or address setting is realized by dialing the code. This method needs to perform a decimal to binary calculation, and then manually dial the code according to the calculation result. Manual dialing is easy to dial wrong. , resulting in the wrong channel or address setting, and using the DIP switch to set the address of the device, it is very difficult to make the device waterproof.
