Abstract

The invention discloses a system used for monitoring a power-off state of a warehouse. The system comprises a voltage transformation module, a rectification module, a filtering module, a voltage stabilizing circuit, a rechargeable battery and a sound-light warning module which are sequentially connected, wherein the voltage transformation module is connected to a phase line input line and a zero line input line, and a relay is connected between the phase line input line and the zero line input line. The voltage stabilizing circuit comprises an NPN triode, a resistor III and a voltage stabilizing tube I. The sound-light warning module comprises a resistor II, a loudspeaker and an LED lamp bead group, wherein the LED lamp bead group comprises a plurality of LED lamp beads which are connected in parallel. By adopting the above structure, the system disclosed by the invention is small in number of applied components, convenient to install, low in cost and capable of giving out a warning to inform the operating personnel when the system is powered off.

Description

technical field [0001] The invention relates to a warehouse environment monitoring technology, in particular to a system for monitoring the power-off state of a warehouse. Background technique [0002] With the development of the economy and the advancement of science and technology, the types of "four products and one device" that people can choose from in their lives, including food, medicine, health care products, cosmetics, and medical equipment, are becoming more and more abundant. Most people will notice the marked production date and shelf life. Storage conditions are often ignored, and storage conditions are the key factors affecting the shelf life. If there is a problem of poor storage before being purchased, the "four products and one machine" people buy "It will deteriorate in advance and easily cause personal injury, so the environmental monitoring of the warehouse where food and medicine are stored is a very important link. [0003] In order to facilitate the m...
