Address coding method and address coding system for cascaded device and lighting system

Abstract

The invention provides an address coding method and an address coding system for a cascaded device and a lighting system. The address coding method comprises the steps that a light modulation signal is output to each light source driving module; when a light source driving module receives a trigger signal, the light source driving module is driven by the trigger signal to start an address coding function, which guarantees the address coding efficiency and control response accuracy of multiple light source driving modules; when each light source driving module starts address coding, the light source driving module counts the corresponding light modulation data; the first pseudo address of the light source driving module is acquired according to the counting result of the light modulation data; the first pseudo address and the reference pseudo address are verified to determine whether the first pseudo address meets the address writing requirement of the light source driving module to complete the real-time update of the system address of the light source driving module, and the accuracy and efficiency of address writing are high; and the address writing process of the cascaded devicehas high compatibility and flexibility.

Description

technical field [0001] The present application belongs to the field of encoding technology, and in particular relates to an address encoding method, an address encoding system and a lighting system for cascade equipment. Background technique [0002] With the rapid development of modern science and technology, lighting equipment has penetrated into various technical fields of people's production and life. Among them, lighting equipment can not only meet people's daily lighting needs, but also bring great convenience to people's production and life. The light source can realize the effect of landscape and lighting, and bring people a good visual experience; and with the continuous improvement of people's lighting performance, technicians need to use integrated and large-scale lighting equipment to achieve better luminous performance. Through The drive circuit can synchronously control multiple lighting devices to emit more coordinated and consistent light sources; and when mu...

Problems solved by technology

[0004] In view of this, the embodiment of the present application provides an address coding method, an address coding system, and a lighting system for a cascaded device, aiming at solving the problem that the traditional technical solution requires an additional coded data stream to be compatible with the light source driving circuit when performing address coding. The performance is poor, and it is impossible to control multiple light source driving circuits through flexible coding, resulting in the problem that multiple lighting devices cannot be applied to the hot-swappable environment
