Use.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of 220VAC smart jacks, it is special
Sign is：Including AC-DC conversion unit, voltage regulation unit, A/D converting units, MCU, battery power supply unit, hand/automatic conversion list
Member, output relay, indicator lamp and buzzer,
Wherein AC-DC conversion unit using rectifier bridge by 220VAC voltage conversions into DC voltage；Voltage regulation unit will be changed
DC voltage afterwards is handled through voltage stabilizing chip, voltage stabilizing to the 0~5VDC voltages that can apply to MCU；A/D converting units will pass through steady
Press the voltage after unit Shape correction to carry out A/D conversions, give MCU and carry out judgement processing, when detection voltage is in normal condition
Powered for MCU system, automatically switched to when in overvoltage or under-voltage condition and be battery powered unit as MCU system power supply；MCU
Judgement processing is carried out to input signal, driving output equipment makes corresponding action；Hand/automatic conversion unit is pressed using stand alone type
Key, select when voltage is in overvoltage or under-voltage condition, automatic or hand off 220VAC power supplies.
Described MCU uses STC89C52 chips.
Described voltage stabilizing chip uses LM7805 chips.
The utility model has advantages below compared with prior art：
1st, it is reasonable in design；
2nd, real-time is high：The utility model realizes low current, weak signal to high voltage, the effective and safe control of high current
System, real-time are high.
3rd, the design effectively protects the safe operation of hub trailing end load equipment, exempts due to under-voltage, over-pressed to equipment
Influence.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is the system block diagram of the utility model 220VAC smart jacks.
Reference:AC-DC conversion unit 1, voltage regulation unit 2, A/D collecting units 3, MCU 4, battery power supply unit 5,
Hand/automatic conversion unit 6, output relay 7, indicator lamp 8, buzzer 9.
Embodiment
As shown in figure 1, the utility model includes：AC-DC conversion unit 1, voltage regulation unit 2, A/D collecting units 3, MCU4,
Battery power supply unit 5, hand/automatic conversion unit 6, output relay 7, indicator lamp 8 and buzzer 9.
220VAC input voltages are converted into DC input voitage, voltage regulation unit 2 by AC-DC conversion unit 1 using rectifier bridge
By the d. c. voltage signal voltage stabilizing after conversion to the 0~5V voltage signals that can apply to MCU, A/D collecting units 3 are to Shape correction
Rear voltage carries out A/D conversions, send MCU4 to carry out judgement processing, and detection voltage is be in normal condition, be still in it is over-pressed or
Under-voltage condition, voltage regulation unit 2 handle the voltage after decompression is handled through voltage stabilizing chip, and when voltage is in normal condition
For MCU4 system power supplies, it is MCU4 system power supplies to be automatically switched to when in overvoltage or under-voltage condition and be battery powered unit 5,
MCU4 is the core of whole system, and it makes corresponding action to input-signal judging, processing, driving output equipment.
Hand/automatic conversion unit 6 selects to automatically cut off when voltage is in overvoltage or under-voltage condition using free-standing button
Socket 220VAC powers, or hand off socket 220VAC power supplies, refers to when voltage is in 180V~240V normal condition
Showing that lamp 8 is grown bright, the adhesive of output relay 7, socket normally exports, when voltage is in 170V~180V under-voltage alert status,
Indicator lamp 8 is glittering at a slow speed, and buzzer 9 sends the tweeting sound of different frequency, prompts custom system to be currently at under-voltage alert status,
When voltage is in 240V~250V overvoltage alert status, indicator lamp 8 is quickly glittering, and buzzer 9 sends piping for different frequency
Sound, custom system is prompted to be currently at over-pressed alert status, when voltage is more than 250V or less than 170V, if hand/automatic conversion
When unit 6 is in manual mode, then hand off socket output voltage is needed, if hand/automatic conversion unit 6 is in auto state
When, system can drive output relay 7 to cut off socket output voltage, simple system is practical, hommization can be docked at very much
