When the televisor of master control output terminal is not activated or the standby of shutting down quits work, when master control electric appliance power is less than setting value, be serially connected in the signal that master control electrical output terminal sample resistance R1 forms, deficiency is so that triode Q1 while amplifying conducting, i.e. triode Q1 cut-off, system power supply makes triode Q2 conducting through resistance R 3, the transmitting of triode Q2 is noble potential very, and sound circuit triggers and starts, and light emitting diode TD1 is luminous, the sound of played pre-recorded, reminds people to cut off the electricity supply.
Audio record circuit, select high level to trigger the sound circuit of playing, and the record button that REC is sound circuit, for recording the content of prompting, reminds voice to record voluntarily, and such as recording, " televisor is standby, please cut off the electricity supply." reminding language.The button of piloting is AN1.
Beneficial effect: TV standby sound prompt device, control circuit is simple, televisor shutdown or standby, when output is less than the power of setting, voice reminder, reminds voice to record voluntarily.Be particularly suitable for the forgetful people's of old man prompting, strengthen electrical equipment user awareness of saving energy, remind people to cut off the electricity supply, and then solve standby energy consumption and standby safety problem.Applicable televisor, home audio-visual electric appliance series, for the use of the operation of cutting off the electricity supply etc. is reminded.
Accompanying drawing explanation:
Fig. 1 is pie graph.
Fig. 2 is circuit diagram.
In Fig. 2: being (1) power switch, is (2) system power supply, is (3) sound circuit,, for detecting control circuit,, for master control output terminal, be (5) (4) (6) peripheral hardware electrical output terminal.
Embodiment:
TV standby sound prompt device, as shown in Figure 1 and Figure 2, the shutdown of master control electrical equipment or standby, when output is less than the power of setting, voice reminder, strengthens electrical equipment user awareness of saving energy, reminds people to cut off the electricity supply.Its device is by power switch, and system power supply, detects control circuit, sound circuit, and master control output terminal and peripheral hardware electrical output terminal form.
Wherein: the system power supply of transformer transformation rectifying and wave-filtering voltage stabilizing for system power supply, or make power supply with the charger for mobile phone of Switching Power Supply.Master control output termination televisor, peripheral hardware electrical output terminal can connect a plurality of electrical equipment, as the electrical equipment such as the top box that picks, video disc player, sound amplifier,
R2-5 is conventional, electric-resistance, key is serially connected in the choosing of the high-power sampled resistance R 1 of sampling of the load variations of master control electrical output terminal energy perception master control electrical equipment, intercept one section of electric furnace heating wire, put terylene sleeve pipe or porcelain tube, copper coin or aluminium sheet and fastened by screw for two ends, and it is firm at two ends, to draw copper wire welding, heat radiation is installed, and when master control electrical equipment is televisor work, resistance R 1 two ends can form alternating voltage more than 0.5V, after rectifying and wave-filtering, be greater than the voltage of 0.6V, make triode Q1 conducting.
K1 is power switch, and C1 is electrochemical capacitor, and Q1-2 is NPN type triode; D1 is diode, and pilot lamp is light emitting diode TD1, TD2, and IC1 is existing finished product audio record circuit, selects high level to trigger the sound circuit of playing here.The button of piloting is AN1, and the record button that REC is sound circuit, for recording the content of prompting, reminds voice to record voluntarily, and such as recording, " televisor is standby, please cut off the electricity supply."
