Ultracapacitor, is again double layer capacitor, electrochemical capacitor, gold electric capacity, farad capacitor, carrys out energy storage by polarized electrolytic matter；It is a kind of electrochemical element, but in the process of its energy storage, chemical reaction does not occur, and this thermal energy storage process is reversible, also just because of this ultracapacitor can hundreds thousand of times of repeated charge；Ultracapacitor can be considered to suspend the porous electrode plate of two reactionless activity in the electrolyte, pole plate powers up, positive plate attracts the anion in electrolyte, negative plate attracts cation, actually form two capacitive accumulation layers, the cation being separated is near negative plate, and anion is near positive plate.
Ultracapacitor is built upon a kind of brand-new capacitor in the interfacial electric double layer theoretical basis that roentgen Helmholtz proposes；It is known that the surface of metal electrode in insertion electrolyte solution there will be, with liquid level both sides, the excess charges that symbol is contrary, so that alternate generation current potential；So, if being inserted simultaneously into two electrodes in the electrolytic solution, and apply the voltage less than electrolyte solution decomposition voltage betwixt, at this moment the positive and negative ion in electrolyte can rapidly to two polar motions under the effect of electric field, and on two, the surface of electrode forms close charge layer respectively, i.e. electric double layer；The polarization charge that the electric double layer that it is formed produces under electric field action with the electrolyte in traditional capacitor is similar, thus producing capacity effect, close electric double layer is similar to plate condenser, but owing to the distance of close charge layer gap ratio ordinary capacitor electric charge interlayer is much smaller, thus there is the capacity bigger than ordinary capacitor.
Double layer capacitor internal resistance compared with aluminium electrolutic capacitor is bigger, therefore, directly can charge in non-loaded resistance situation, if there is the situation of overvoltage charging, double layer capacitor will be opened a way and will not be damaged device, and this feature is different from the over-voltage breakdown of aluminium electrolutic capacitor；Meanwhile, double layer capacitor, compared with rechargeable battery, can carry out not current-limiting charge, and charging times up to 10^6 time more than, therefore electric double layer capacitance not only has the characteristic of electric capacity, also has battery behavior simultaneously, is a kind of novel specific components between battery and electric capacity.
So super capacitor is substituted for the lithium battery in electric intelligent instrument, including electric power list three-phase intelligent instrument, and the product such as load management terminal, concentrator, harvester；And lithium battery power failure function when electric intelligent instrument has a power failure can also be substituted.
But super capacitor is running into electrical network instability, alternating voltage step-down, when making intelligence instrument Power supply belt loading capability diminish, super capacitor still can normal operation, so may result in intelligence instrument Power supply belt loading capability inadequate, so that intelligence instrument irregular working, produce various error, and then cause various dispute.
Summary of the invention
The invention aims to provide a kind of and can make the out-of-work hardware circuit for the electric discharge of intelligence instrument charge of super capacitor when electrical network shakiness, alternating voltage step-down.
The present invention is achieved through the following technical solutions: a kind of hardware circuit for intelligence instrument charging and discharging, it is characterized in that: include VCC power supply, first resistance, second resistance, 3rd resistance, 4th resistance, diode, audion, detection module, super capacitor, first micro-control unit, second micro-control unit, described VCC power supply connects one end of the first resistance, the emitter stage of the other end connecting triode of described first resistance and one end of the second resistance, the base stage of the other end connecting triode of described second resistance, the base stage of described audion is also connected with one end of the 3rd resistance, the other end of described 3rd resistance connects the second micro-control unit；The colelctor electrode of described audion connects the positive pole of diode, one end of the negative pole connection detection module of described diode and one end of the 4th resistance, and the other end of described detection module connects one end of described super capacitor, the other end ground connection of described super capacitor；The other end of described 4th resistance connects described first micro-control unit；Described super capacitor is polar capacitor；Described audion is PNP type triode.
The present invention makes to work as electrical network shakiness, alternating voltage step-down by increasing the circuit of audion and some resistance composition, intelligence instrument Power supply belt loading capability is made to diminish the super capacitor no longer normal operation of intelligence instrument in situation, it is prevented that because the intelligence instrument irregular working that load capacity causes not.
The invention have benefit that: 1) this circuit can detect the power consumption of super capacitor automatically, and raising efficiency, record data are easy to counter looking into simultaneously；2) under the situation of, alternating voltage step-down unstable at electrical network, super capacitor does not work, and under rated voltage or high-tension situation super capacitor normal operation, it is prevented that because the intelligence instrument irregular working that load capacity causes not；3) power consumption under super capacitor duty can be detected the moment, for effectively analyzing offer foundation.
