Embodiment Construction

[0014] Electric standby voice prompt device, such as figure 1 , figure 2 As shown, when the main control appliance is off or on standby, and the output is less than the set power, a voice reminder will enhance the awareness of energy saving of appliance users and remind people to cut off the power. The device is composed of a power switch, a system power supply, a detection control circuit, a voice circuit, an indicator light, a main control output terminal and an output terminal of peripheral electrical appliances.

[0015] Among them: K1 is the power switch, and the output terminals of peripheral electrical appliances can be connected to multiple electrical appliances. T1 uses a 6-12 V, power 4W power transformer; C1-2 is an electrolytic capacitor, C3-4 is a ceramic capacitor, R1-6 is an ordinary resistor, Q1 is an NPN transistor; D1-5 is a diode, and the indicator light is luminous Diodes TD1, TD2, and IC1 are comparators LM358; IC2 uses L7805 three-terminal voltage regulato...

Abstract

The invention discloses an electric appliance standby voice prompting device. The device is characterized by consisting of a power switch, a system power, a detection control circuit, a voice circuit, an indicator light, a main control output end and an external electric appliance output end. The control circuit is simple and mainly controls an electric appliance in an off or standby state, when an output power is less than a set power, voice is generated for prompting, and the prompting voice can be recorded by users. The energy-saving consciousness of electric appliance users is increased, the users are prompted to cut off the power, and furthermore, a standby safety problem is solved. The device is particularly suitable for prompting the blind, the old and forgetful men, is suitable for a series of related standby energy-consuming electric appliances such as computers, multimedia systems, televisions, home audio systems, kitchen appliances and production and living electric appliances, and is used for prompting power cut-off operation and the like.

Description

Technical field: [0001] The invention belongs to the field of electronic control, and relates to a device for voice prompting people to cut off the power supply when an electrical appliance is in standby. Background technique: [0002] When electrical appliances are on standby, people tend to forget to turn off the power and don’t pull out the plug. They are accustomed to leaving electrical appliances on standby. Long-term standby consumes power, which is not conducive to electrical maintenance. Power consumption also affects the life of electrical appliances and even causes accidents. Caused. Summary of the invention: [0003] The object of the present invention is to provide a device for voice prompting people to cut off the power when the electrical appliance is in standby; detect the change in the current of the main control electrical load, the main control electrical appliance is shut down or standby, and the output is less than the set power, and the voice prompts people to...
