The invention provides a multi-path power control system and a multi-path power control method for PDLC (Polymer Dispersed Liquid Crystal) dimming films. The multi-path power control system for the PDLC dimming films comprises a PDLC dimming film matrix, at least two multi-path power control modules and a main control unit, wherein the PDLC dimming film matrix comprises at least two PDLC dimming modules; the at least two multi-path power control modules are connected with each path of PDLC dimming film of the PDLC dimming modules, and are used for converting connected direct current into alternating rectangular wave current matched with an obtained alternating rectangular wave information group and supplying the alternating rectangular wave current to each path of PDLC dimming film; the main control unit is connected with the at least two multi-path power control modules and is used for outputting the alternating rectangular wave information group matched with preset addressing of the multi-path power control modules by executing configuration information in an editable configuration file; the alternating rectangular wave information group comprises the alternating rectangular wave information of each path of PDLC dimming film. According to the multi-path power control system and the multi-path power control method for the PDLC dimming films, the gray level and the light transmittance of the dimming films can be more accurately controlled by controlling the at least two multi-path power control modules according to the configuration information of the editable configuration file, and a control effect set by a user is achieved.
Description
technical field [0001] The invention relates to the field of power supply control, in particular to a PDLC dimming film multi-channel power supply control system and method. Background technique [0002] At present, the PDLC dimming film is a polymer dispersed liquid crystal dimming film. When an external voltage is applied to the outside, it will affect the light transmission rate, so that it can realize the change of full transparency, opacity to middle gray level, and is used in commercial space. Decoration, hotel decoration, projection display and other fields. [0003] In the application of PDLC dimming film, the dimming parameters of the dimming film often have different requirements in different application scenarios, and the states of multiple groups of dimming films must be linked together, in order to meet the needs of such users , How to control the power supply of multiple sets of light-adjustable films to make the PDLC light-adjustable film display the expected...
