The electrical power is too large or too small voice prompt device

Abstract

The voice prompt device for electrical appliance power is too large or too small, which is characterized in that it consists of a power switch, a system power supply, a detection amplifying circuit, an excessive power detection circuit, an excessively low power detection circuit, a voice circuit, a main control output end and an external electrical appliance output end composition. The control circuit is simple. When the main control appliance is turned off or in standby, and the output is less than the set power, a voice reminder will remind people to cut off the power supply; enhance the energy saving awareness of electrical appliance users, remind people to cut off the power supply, and then solve the standby safety problem; When the load is working, the power becomes larger, and the overcurrent current is greater than the set value, a voice reminder will remind people to cut off the power supply in time, which can prevent damage to electrical appliances, equipment and workpieces caused by overloaded work and prevent accidents. It has a prompting function for remote monitoring of the working status of electrical appliances. The reminder voice can be recorded by itself. It is especially suitable for the reminder of the blind, the elderly and the forgetful, and the voice prompts people to cut off the power supply or other operation prompts.

Description

Technical field: [0001] The invention belongs to the field of electronic control, and relates to a device for prompting people to cut off the power supply by voice when the electric power is too high or too low. Background technique: [0002] When electrical appliances are in standby, people tend to forget to turn off the power supply, do not pull out the plug, and are accustomed to letting electrical appliances stand by. Standby for a long time consumes power, which is not conducive to the maintenance of electrical appliances. The power consumption also affects the life of electrical appliances, and even causes accidents. This is because the power supply is not cut off. Caused. However, there are many accidents caused by electrical overcurrent and short circuit. When electrical equipment is overloaded, people do not find it, and it is easy to damage electrical equipment, equipment and workpieces, and even cause accidents. Invention content: [0003] The purpose of the pr...
