Intelligent UPS with logic judging function

Abstract

This invention relates to one intelligent power without power with logic judgment function in industry control system power supply system, which is characterized by the following: the city power is connected to the integral circuit through voltage converter and print circuit board; the memory bottle is connected to the constant circuit and automatic switch circuit;; LED status display panel is connected to circuit board through wire panel and the I / O logic output is connected to display. The invention power can monitor remote load normal connection status.

Description

technical field [0001] The power supply of the invention belongs to the field of power supply for industrial control systems, and is particularly suitable for directly supplying power to sensor control systems that need to ensure data continuity. Background technique [0002] In the prior art, uninterruptible power supply is generally selected when supplying power to the sensor control system that requires data continuity. intermittent power. However, since sensors and transmitters such as pressure, displacement, flow, temperature, humidity, etc. are often connected outdoors and have a certain distance from the controller working room, the connected power lines and data lines are exposed. If there is an open circuit or short circuit in the line Abnormality will cause data interruption. Since some sensor signals do not output pulses during the intermittent period, the controller cannot judge whether it is an intermittent data or a fault, which will cause data loss. The gene...

However, since sensors and transmitters such as pressure, displacement, flow, temperature, humidity, etc. are often connected outdoors and have a certain distance from the controller working room, the connected power lines and data lines are exposed. If there is an open circuit or short circuit in the line Abnormality will cause data interruption. Since some sensor signals do not output pulses during the intermittent period, the controller cannot judge whether the data is intermittent or faulty, which will cause data loss.

The general uninterruptible power supply does not provide the judgment, indication or reminder of the state of the load open circuit, nor does it provide the corresponding logic state output signal
