A control assembly of centralized power supply for emergency lighting

Abstract

The invention discloses a control assembly of emergency lighting centralized power supplies, which includes an emergency lighting controller and a plurality of emergency lighting centralized power supplies. The emergency lighting controller is electrically connected with the emergency lighting centralized power supplies through a CAN bus, and information interaction is realized between the emergency lighting controller and the emergency lighting centralized power supplies. Each emergency lighting centralized power supply is connected with a plurality of emergency lighting lamps. Each emergencylighting centralized power supply includes a two-wire general circuit module and a three- or four-wire general circuit module, wherein the two-wire general circuit module is used for being connectedwith a two-wire emergency lighting lamp, the three- or four-wire general circuit module is used for being connected with a three- or four-wire emergency lighting lamp, and the two-wire general circuitmodule and the three- or four-wire general circuit module are in communication connection. The control assembly has the following advantages and effects: the control assembly can support two-wire, three-wire and four-wire emergency lighting lamps at the same time; the use of emergency lighting lamps is no longer limited; and the difficulty of project use and design and the complexity of maintenance can be reduced.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a control assembly of a centralized power supply for emergency lighting. Background technique [0002] The bus mechanism of existing emergency lighting fixtures on the market generally has two-wire system, three-wire system and four-wire system. However, the centralized power supply for emergency lighting on the market now generally only supports emergency lighting fixtures with one bus mechanism, which results in the limitation that only one specific bus mechanism can be used in the same project, especially for some segmented design and construction projects. For the project, the design unit had to use the pre-set bus, which created great difficulties for the overall control of the project. Contents of the invention [0003] The purpose of the present invention is to provide a control assembly of centralized power supply for emergency lighting, which can simultaneously ...
