Embodiment Construction

[0008] The present invention will be further described below via accompanying drawing:

[0009] as attached figure 1 As shown, the UPS power supply equipment for preventing power disturbance in the security control system is provided with a single-chip microcomputer 1 for preventing power disturbance in the security control system. The security system line 2 redundant switching switch conduction line of the electrical appliance is the same as the protective fuse, and the protective fuse is provided with a feedback signal generator of the security system line 2 with a UPS power supply, and the security control system prevents power from Disturbed single-chip microcomputer 1 fuse with UPS power supply security system line 2.

[0010] Through the single-chip microcomputer 1 that prevents power disturbance in the security control system, the single-chip microcomputer 1 that prevents power supply disturbance in the security control system is connected to all security system lines ...

Abstract

Ups (uninterrupted power supply) power supply equipment for preventing power disturbance in a safety monitoring system is characterized in that a single chip microcomputer for preventing power disturbance in the safety monitoring system is arranged and is used for controlling a redundant switch to conduct a line and a protective fuse towards all security and protection system lines with UPS power supplies subjected to power disturbance, the protective fuse is provided with a feedback signal generator for the security and protection system lines with the UPS power supplies, and the single chip microcomputer for preventing power disturbance in the safety monitoring system regulates the security and protection system lines with the UPS power supplies by the fuse. The problem that ripple disturbance frequently appears on a display in the security and protection system due to the fact that a power supply of a power supply system is not 'clear' is solved conveniently and rapidly.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a UPS device for preventing power disturbance in a security control system. Background technique [0002] Because the phenomenon of ripple disturbance on the display often occurs in the security system, this phenomenon is often caused by the power supply of the power supply system being unclean. The power supply referred to here is not "clean", which means that there are interference signals superimposed on the normal power supply. And this kind of interference signal on the power supply mostly comes from the equipment using thyristor in the power grid. Especially high-current and high-voltage thyristor equipment pollutes the power grid very seriously, which leads to the uncleanness of the power supply in the same power grid. For example, there are high-power thyristor frequency modulation and speed regulating devices, thyristor rectifiers, thyristor AC-DC conversion devices,...
