Embodiment
Hereinafter, more fully the present invention is described now with reference to accompanying drawing, various embodiment shown in the drawings.But the present invention can implement in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, provide these embodiments to make the disclosure will be thoroughly with completely, and scope of the present invention is conveyed to those skilled in the art fully.
Hereinafter, with reference to the accompanying drawings exemplary embodiment of the present invention is described in more detail.
With reference to accompanying drawing 1-9, the following circuit that intelligent power supply switch of the present invention comprises MCU control circuit and is connected respectively with described MCU control circuit:
Supply module, it provides power supply to described MCU control circuit;
Four road electric voltage observation circuits, it is for detecting voltage;
Four tunnels control output circuit, and it is for controlling the opening and closing exported;
Product working status display circuit, is used to indicate operating state;
And the quick circuit for alarming of honeybee and special installation control circuit.
This product is intelligent power supply switch, and provide four road electricity power supplys to select, in four groups of power supplys, select preferential power supply group for user, order presses L1-L4; Possesses high-low pressure defencive function; the operating state instruction of each group of circuit and delay working warning device; possesses memory function and self-clocking whether operating time year and a day; ultra-wide working range: 85-300V; low-power consumption (being less than 3W), circuit structure is unique, uses micro-chip processor to control; precision is high, is the requirement of huge numbers of families.
Technical characteristic:
Normal use rated voltage: 85-300V 50/60HZ
Normal control output voltage range: 170-255V or 90-135V 50/60HZ
Rated current: 30A
No-load power consumption :≤3W
This circuit is primarily of seven most compositions, respectively: four road voltage commutations corrections (because be that the same N of four groups of power supply networks is extreme, also needing both positive and negative polarity to correct except stream), supply module, four road electric voltage observation circuits, four tunnels control output circuit, the quick circuit for alarming of honeybee, special installation control circuit, product working status display circuits.
When four road electricity have simultaneously electricity or wherein a certain group or wherein two groups have an electricity time, by rectification correcting circuit module, obtain direct voltage, then two kinds of direct voltages (24V and 5V) of needs are converted to through supply module, supply MCU and relay work respectively, normally start successfully for whole circuit, then remove by MCU the magnitude of voltage detecting corresponding four road voltages, judge whether in normal output area, and then according to the priority condition Sequential output of L1-L4 that road voltage corresponding, at this therebetween, time delay 10 seconds also starts the quick circuit for alarming of honeybee, object notifies that user notes exactly, to power at once, wait for that indicator light is in flicker, after time delay, export and show corresponding operating state, in addition, when any road voltage of L1-L3 normally exports, special installation control circuit starts output, otherwise close.
After circuit normally starts, MCU self-clocking, after reaching shelf lives, instruction automatic distinguishing of guaranteeing the quality, there is memory function the time that certainly each power-off adds up, after each startup, recovers data and continues the timing that adds up.If after reaching shelf lives, from then on not cumulative.
This product has four tunnels to power, so need four groups of rectification correction modules and four groups of electric voltage observation circuits, the operation principle often organized is the same, so here one group is made clear, after three groups be the same.
This four tunnel powers, the N pole of input is and (is namely connected together) together, L pole is only had to separate respectively, L1 is one group, L2 is two groups, L3 is three groups, L4 is four groups, here one group is said, D1 and D2 forms halfwave rectifier, in addition, also has a function, it is exactly polarity correction, because we need the voltage detecting each group, just need one altogether, here say commonly, the ground of all exactly groups is all unified (comprising the ground of supply module), so single-chip microcomputer could produce loop, could detect correct, also just because of the composition of D1 and D2, also prevent Kickback voltage, interfere with other group, Here it is in the place of the design uniqueness of the same industry, greatly reduce unnecessary circuit and the error because of electronic component, and it is not accurate to produce the voltage detecting each group, also substantially increase this product own loss simultaneously.
D17 R1 R2 R3 C1 D3 form electric voltage observation circuit; by D17 rectification (interchange is become direct current); then by R1 R2 R3 form dividing potential drop (because to chip power supply is the highest can only 5V; so give chip detection again after needing these three electric resistance partial pressures); D3 is protection diode, and when overtension certain value, dividing potential drop shunting carried out by this diode; achieve protection effect, avoid causing the large loss of user.
The foregoing is only embodiments of the invention, be not limited to the present invention.The present invention can have various suitable change and change.All any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
