Two-bus centralized control emergency power supply box with redundant design

Abstract

The invention relates to the technical field of bus communication equipment, and specifically discloses a two-bus centralized control type emergency power supply box with redundant design, including a box body and a heat dissipation part; the inside of the box body is provided with a main circuit breaker and a plurality of switching power supplies; The interior of the box is equipped with a control board, which is electrically connected to the switching power supply; the box is equipped with a charger, which is electrically connected to the main circuit breaker, and the charger is electrically connected to the control board; the inside of the box is equipped with a rechargeable The battery pack, the rechargeable battery pack is electrically connected to the control main board through the battery protector; the control main board includes a circuit board and a central processing unit arranged on the circuit board, and the circuit board is provided with multiple two-bus control modules and multiple switch controls. A conversion module and multiple output protection modules, one two-bus control module corresponds to a switch control-transformation module, an output protection module and a switching power supply. The invention has the characteristics of no signal interference and redundant power supply + redundant communication design.

Description

technical field [0001] The technical field of bus communication equipment of the present invention, in particular relates to a two-bus centralized control emergency power supply box with redundant design. Background technique [0002] The emergency power supply box is a device with a backup battery pack, which can provide emergency power supply for the load in case of emergency / fire. The traditional emergency power supply box only has the function of emergency power supply, but not the function of data communication. Although some existing emergency power supply boxes have power supply and communication functions, the power supply and communication functions are separated. A power supply module and a communication router need to be installed in the collector box, and the power supply module needs to use a power supply cable for power supply. For transmission, communication routers need to use communication cables for signal transmission, and signal interference will occur b...

Problems solved by technology

[0003] For example, a two-bus control module is connected to a 36V large switching power supply. In actual use, it is found that the quality of some brands of switching power supplies is uneven. Once the switching power supply is damaged, the whole machine cannot be powered for emergency; there is another In this kind of emergency power supply box, a two-bus module is matched with multiple 36 switching power supplies in series for use, and multiple switching power supplies are used in series, and as long as one switching power supply is damaged, all output circuits of the power box cannot be used. If there is no load power supply, the emergency function cannot be realized; at the same time, a bus communication module can only carry 250 terminal communication points normally, and the number of terminal communication points that can be carried is relatively small. When the number of terminal communications is relatively large, the communication is unstable, and Once there is a quality problem with this bus communication module, it will affect the communication of the entire emergency power box

[0004] Therefore, the existing emergency power box with power supply + communication functions has problems such as signal interference, failure to realize emergency functions, and low data communication capabilities.
