According to the main technical schemes of the invention, when the external electricity utilization equipment is switched on, energy can be provided for the battery and a system through an electricity obtaining mutual inductor; the voltage of the battery is monitored real time, so that overcharge can be prevented; and AC power supply condition is monitored real time, and power source supply of the system is cut off when power failure occurs. With single-live line electricity obtaining equipment lithium battery electricity charging and power supply management method adopted, corresponding electricity obtaining measures can be realized so as to supplement energy loss of the lithium battery when the external electricity utilization equipment is switched on or switched off, and instantaneous large current can be provided for the system; and the battery is free of maintenance in a use period of the equipment; and over discharge and power-off protection functions can be realized.
Description
Technical field
A kind ofly ensure supplying cell charging in single fiery power taking equipment, protect and prevent the circuit design that still works when having a power failure.
Background technology
The fiery power taking equipment of the list of lithium battery is utilized mainly to there is problem: 1, when power consumption equipment is connected, especially when using mechanical switch, not easily collect enough Power supply embedded device work, during long-term connection, only discharging under the state of not charging in place by battery, easily causes over-discharge can; 2, when equipment is disconnected for a long time, because the electric current under stealing from live wire gives lithium cell charging always, and the electricity of charging is slightly larger than the electricity of system consumption, and therefore cell voltage raises gradually, easily causes overcharging; 3, when having a power failure, (Alternating Current Power Supply stoppings) not needing to monitor power consumption equipment, and namely necessity of not working on of embedded device, will close its power supply from the angle of energy-conservation, as far as possible the electricity of maintenance battery.In sum, this circuit design is for overcoming above-mentioned shortcoming, adapting to environment for use and design.
Summary of the invention
The purpose of design of this switch is: design a circuit, and it can be all the electricity of lithium battery replenish lost when no matter whether power consumption equipment connected, and can prevent the generation of the phenomenon that overcharges to battery simultaneously; When stopping when powering, automatically can close the power supply supply of battery, reducing electric quantity consumption as far as possible.
For achieving the above object, following technical scheme is adopted:
1, by single fiery way to take power, when power consumption equipment is closed, (when the lamp that such as switch panel controls is closed) is lithium cell charging; 2, when power consumption equipment is connected, (when the lamp that such as switch panel controls is opened) obtains certain electricity by electricity-getting mutual inductor is lithium cell charging; 3, testing circuit Real-Time Monitoring cell voltage is set, when cell voltage reaches certain threshold values, cuts off charging supply; 4, Real-Time Monitoring alternating current supply situation, when having no progeny in the supply of confirmation alternating current, cuts off the power supply supply of embedded system, to prevent unnecessary battery power consumption.
There is following characteristics and beneficial effect:
(1) lithium battery can provide instantaneous larger current for embedded device, meets the larger curent change that communication, output etc. bring to system while ensureing supply power voltage quality.
(2) no matter when whether power consumption equipment is connected, there is corresponding power taking measure, ensure the energy loss of supplementing lithium battery in time.
(3) charge protection makes lithium battery overcharge, and system is in even running for a long time.
(4) supply of cutting off the electricity supply during power-off effectively can prevent the over-discharge can of battery, is beneficial to the storage of control assembly, transports and deal with long-term idle state.
(5) by taking these measures, equipment battery in life cycle can be made non-maintaining.

Embodiment
The course of work:
For single fiery power taking intelligent switch panel, when electronics, mechanical switch group are finally selected to close electric light, live wire enters switch and forms a loop by turn off the light power-supply circuit, light fixture and zero line of device interior, and switch passes through this loop power taking and charges to battery; When electronics, mechanical switch group are finally selected to turn on electric light, live wire electric current is turned on light electricity-getting mutual inductor, and switch is by the secondary circuit power taking of this instrument transformer and charge to battery; Battery voltage monitoring unit Real-Time Monitoring cell voltage, the charge switch in charge closing being controlled when cell voltage reaches fixed threshold values is forbidden charging to battery; Charging control unit is according to the state of two power-supply circuits, and real-time judge alternating current supply situation, when supplying interruption, sending power supplying control signal and closing power switch to forbid to system power supply.
