Digital lamp control method and system

Abstract

The present invention discloses a digital lamp control method and system. The method core is that: first, obtaining present position information and target position information of lamp; then, comparing a predetermined value with an absolute value of difference between present position value of present position information and target position value of target position information, and controlling position state of lamp according with comparative result. Automatized closed ring control of lamp can be realized by using said method and system, light arrangement accuracy and efficiency are increased largely, and arranged scene can be reappeared accurately.

Description

technical field [0001] The invention relates to a technology for automatically controlling lamps, in particular to a digital closed-loop control method and system for accurately controlling lamps based on a microprocessor. Background technique [0002] In current lighting applications, especially in professional lighting fields such as studios, theaters or building lighting, it is necessary to adjust the focus, level, and pitch of the lamps to achieve lighting effects. At present, the "simulation semi-automatic adjustment" technology is mostly used to adjust the lamps and lanterns: the focus, level and pitch parts of the lamps that need to be adjusted are connected to the remote manual operation console through cables, and the operation console is equipped with selection keys and forward and reverse rotation directions. key, the selection key and the direction key are connected with the DC motor, and the other end of the DC motor is connected with the transmission mechanism ...

AI Technical Summary

Problems solved by technology

This design will bring a lot of inconvenience in on-site application, because when the position state of the luminaire is adjusted to meet the requirements, it needs to maintain this state until the next re-lighting

However, with this method, the lamp needs to return to the "starting position" when the power is turned on again after a power failure, which changes the adjustment position before the power failure, so the lamp needs to be readjusted after each power-on, which brings inconvenience to the operator, especially the It is more inconvenient when there are more, and it also reduces work efficiency

In addition, this method does not have the function of self-calibration during dynamic operation, that is, the lamp may encounter resistance or short-term external interference during operation to make its position deviate from the set target position. When the external force or interference is withdrawn, the lamp will not automatically Return to the set target position, affecting the adjustment accuracy and lighting effect

Moreover, when multiple scenes are alternately repeated, this method does not have a memory storage function, and cannot achieve accurate reproduction of the laid out scenes.
