Phase long-time trickle can cause damage battery.Being not easy to different user timing, surely unrestricted choice uses;It cannot know in time
Power work situation, is not easy to user security use.
Utility model content
The utility model is single in order to overcome existing Switching Power Supply electric energy output selection mode, and long-term long-time trickle is to electricity
Pond damages, it is impossible to while meet a variety of output selections of user, the technology back ofs the body such as power supply itself working status quality can not predict
The defects of under scape and deficiency, there is provided a kind of power supply for having the function of to control metering switch.
To achieve these goals, the technical solution adopted in the utility model is:Metering switch power supply, Switching Power Supply input
End connection power cord, the Switching Power Supply are outwards powered through relay electronic switch, and the Switching Power Supply is master control chip power supply,
Main control chip output on-off signal to relay electronic switch, the main control chip includes:
Driving unit:On-off signal is exported to relay electronic switch;
Mode selecting unit:Determine to send the qualifications of break signal, qualifications to the break-make for exporting setting judges
Unit;
Timing unit:The time of relay electronic switch output electric energy is obtained, and time signal is delivered to break-make and is judged
Unit;
Metering units:The electricity of relay electronic switch output electric energy is obtained, and electric quantity signal is delivered to break-make and is judged
Unit;
Break-make judging unit:According to whether the qualifications for completing setting export break signal to driving unit.
Push-button unit output parameter Regulate signal to main control chip mode selecting unit.
The output terminal of the Switching Power Supply adopts volt circuit and current detection circuit equipped with power supply, the power supply adopt volt circuit and
Current detection circuit exports sampled signal to main control chip.
The power supply adopts the constantan wire resistance that volt circuit is the output terminal for being connected to Switching Power Supply, the current detection circuit
MAX4172 chips conversion current signal is used to be delivered to main control chip for voltage signal.
The main control chip uses STM32 chips, and the main control chip output parameter signal to display module is shown.
The utility model has the advantage of:
1st, science and technology is maked rapid progress, with the progress in epoch and the continuous popularization of intelligent level, the life water of people
Flat, quality is gradually lifted, also original stronger to the demand of "smart" products, and intelligent switch power source is as a kind of daily necessities
Naturally it is to have to make improvements realization intelligence;
2nd, the utility model Switching Power Supply increases model selection than original Switching Power Supply, and timing, quantify, free three kinds of moulds
Formula, for user add using selection be more convenient for user use, at regular time and quantity shut-off and freely intelligence shut-off more effectively protection
Overcharging during charging use and long-time trickle damage caused by battery, LCD MODULE display real-time voltage, defeated
Go out energy, charging interval, itself safety check situation and also add color for power supply, the user that is more convenient for observation easy to use;
3rd, the intelligent measurement module of the utility model Switching Power Supply is better than market regular tap power supply, market Switching Power Supply
Safety detection module is had no, but cannot be guaranteed that user's is safe to use.This Switching Power Supply carries work safety condition detection simultaneously
Real-time display, when power failure or damage, power detecting control system turns off Switching Power Supply, effectively avoids failure
Use, reduce the risk of the damage and user's personal safety to battery.
Brief description of the drawings
The content expressed below attached drawing in the utility model specification is briefly described:
Fig. 1 is metering switch power principle figure.
Embodiment
The utility model adds to adopt pressure and adopt current circuit and voltage and current is sampled in original switched power output, uses
STM32, which gathers Current Voltage and adds up in inside progress electric energy, exports computing, with OLED to voltage power, charging duration, work
Situation is shown.Add manual switch to connect STM32 with electronic switch in Switching Power Supply input terminal and intelligence is carried out to Switching Power Supply
Shut-off.On STM32 plus control circuit is pressed key control timing with three, is quantified, free Three models, separately sets two buttons and is used for
Time, energy selection are carried out under pattern at regular time and quantity.Compare the reality output electric energy and setting electric energy of collection, STM32 is to electronics
Switch carries out intelligent shut-off, and power supply can be accomplished full of power-off under free schema, plays the anti-overcharge anti-long-time trickle of intelligence
Effect.Compare Switching Power Supply reality output data inside STM32 and judge Switching Power Supply real-time working quality with laboratory data
With working performance and prompt.
Specifically as shown in Figure 1, newly adding an intelligent measuring system, control unit on the basis of existing efficient Switching Power Supply
Divide and use STM32 monolithics and realization, in switched power output plus a sample circuit.Add a health on the main line of output terminal
Copper wire resistance, main line virtual voltage can be calculated according to trial scale by carrying out sampling to voltage in the case where loss is minimum.It is right
It is that voltage signal calculates main line electric current for STM32 collections to convert current signal with MAX4172 chips when electric current is sampled, then
Carry out electric energy in STM32 to calculate and add up in real time, the electric energy and charging duration of the voltage calculating of collection carry out on OLED
Display.
STM32 control circuits set three buttons to be used for selecting timing, quantify, free Three models, separately set two buttons
For selecting duration and value under pattern at regular time and quantity, two buttons are plus-minus button.Set under timing mode and often add and subtract
When stepping 0.5 of button is small, when reaching setting duration, closed by microcontroller control electronic switch relay controlling switch power supply
Disconnected, power supply does not recharge;Often plus-minus stepping 1kwh of button is set under quantitative model, when output electric energy reaches setting
Value, controls electronic switch relay controlling switch power remove, power supply is stopped by microcontroller;Under free schema, switch
Power supply adopts flow module detection output current, and when battery is full of, output current is decreased to milliampere, and control power supply is detected certainly by STM32
Dynamic shut-off, avoids enter into long-time trickle state.
Collection output main line voltage and calculate delivery efficiency inside STM32 with original setting laboratory data contrast, when with
Switching Power Supply operation irregularity is judged when laboratory data is not consistent, STM32 can " power supply be different for prompting in time in OLED display screen
Often " printed words, and meeting automatic lockout switch power supply, if having repaired be able to cannot still work normally when plugging again, power supply can be again
It is secondary to be turned off, power supply normal work normal until repairing completely.Avoiding power supply irregular working makes battery cause danger or right
Battery produces infringement.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implements and from above-mentioned
The limitation of mode, if the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or not
It is improved by the present invention design and technical solution directly apply to other occasions, the scope of protection of the utility model it
It is interior.
