Below in conjunction with specific embodiment, the utility model is further described, consults Fig. 2:
The present embodiment with home lighting load for 100W for specific embodiment is told about in detail to the utility model, the utility model devises dual-electrode protecting circuit.
Wherein the first protective circuit comprises operational amplifier LM358, comparator LM393, metal-oxide-semiconductor and the first resistance; change with the A/D of intelligent controller 120 the operational amplifier LM358 be connected and be connected one end by the first resistance with metal-oxide-semiconductor (in figure GB1 position); metal-oxide-semiconductor (GB1) other end is connected with comparator LM393, and the first resistance R7 and triode Q1 is connected to 18 pins (in figure P1.7) of intelligent controller.
In Fig. 2: P1.6 is single-chip microcomputer 18 pin; P1.7 is single-chip microcomputer 19 pin; P3.2 is single-chip microcomputer 6 pin.
Concrete, the first protective circuit have employed the overcurrent of R7 (0.01 Ω constantan wire) and the device such as discharge circuit LM358, comparator LM393 composition, A/D conversion (i.e. P1.7) of short-circuit detecting circuit cooperation single-chip microcomputer (i.e. intelligent controller) 19 pin and external interrupt response and realizes protecting LED illumination System.First resistance R7 and triode Q1 is connected to 18 pins (i.e. P1.6) of intelligent controller, and the A/D conversion of 19 pins is used as over-current signal identification, when electric current exceedes rated current 20% and maintains more than 30s, confirms as overcurrent; Short circuit current can be set as 20A, and the response time is the millisecond order of magnitude.
Wherein external interrupt subprogram at intelligent controller inediting, can be able to be compiled as:
voidservise_TNTO0interrupt0using1
If(P3_2) and // high level, think interference signal triggered interrupts
return
Delay1(5000); // 10ms time delay
if（P3_2=0）
{ load_switch_1=LSTOP; // load switch 1 closes
LOOP1_DL=1; Put load short circuits mark
}
}
External interrupt subprogram should be high-priority interrupt; when establishment subprogram realizes load overcurrent, short-circuit protection; take into full account that load starts and can produce the impulse current being several times as much as rated current instantaneously; impulse current maintains 3ms ~ 5ms; should take measures on software, avoid the erroneous judgement that short circuit and load are opened.After determining load overcurrent, short circuit, cut off load and export.After load break, at set intervals, as 20ms, load switch is connected in examination, when discovery overcurrent, short-circuit signal are eliminated, then recover the output of load, otherwise load switch still remains open.
Second level protective circuit comprises the electrical fuse F for reducing operating current by increasing resistance, and electrical fuse one end solar panel connects, and the electrical fuse other end is connected with comparator.
Concrete, the second level have employed electrical fuse protection, when there is overcurrent or short circuit; when the electric current flowing through electrical fuse F increases suddenly, temperature rises thereupon, and its resistance increases greatly; operating current significantly reduces, and reaches protective circuit object, and the response time is number of seconds magnitude.Overcurrent is cancelled or after short circuit recovery, electrical fuse F reverts to low-impedance conductor, need not any artificial replacing or maintenance.
In specifically practicing, after system have employed above two class protection measure, after reaching a few hours time load short circuit experiment, still there is not circuit burnout phenomenon in controller.Solve and can only carry out disposable protection to circuit with traditional insurance silk; once burn the problem that must artificially change; compare with the system reopened after needing hand-reset or power-off after short circuit, the security performance that also there is obvious advantage, simplify maintenance, improve system.
For controller module can participate in Fig. 3 when embody rule is implemented, it is voltage detecting flow chart;
Micro controller module, for carrying out Charge Management according to pre-set threshold value to storage battery, the battery pack open circuit when solar panel normal output voltage, switching off load.In battery pack open circuit protection: just in case battery pack open circuit, if when solar cell charges normal, microcontroller is by switching off load; be not damaged with proof load; if when not charging at night or solar cell, controller can not get electric power due to self, do not have any action.If judge whether magnitude of voltage is greater than 30V, if be greater than, charge closing Switch Controller storage battery carries out charge protection.If detect voltage will call floating charge program lower than 30V higher than 26.4V and all fill program and charge to storage battery, if detection voltage calls preliminary filling program lower than 26.4V higher than 22V.When being in night, if detect voltage to be less than 22V, closing load switch, then open load switch higher than 22V.
In the specific implementation, its circuit working principle refers to Fig. 4 to the utility model:
Solar panel is connected with storage battery by diode D1, and storage battery is in parallel with triode Q1 again, and storage battery is connected with inverter with triode Q2, Q3 by diode D2, D3, D4, D5, and in the alternating current input load that inverter is changed.
Shine upon on solar panel, solar cell is started working, and diode D1 is worked with triode Q1, and storage battery starts electric power storage, and after treating storage battery electric power storage, according to the setting of program, Q1 reaction, storage battery stops electric power storage.Time pitch-dark to evening, the program of setting starts, and make storage battery start electric discharge, diode D2, D3, D4, D5 conducting, triode Q2, Q3 work, and make load luminous, until the next morning, the program preset acts on again, and lighting is extinguished; In time shining upon solar panel, storage battery starts electric power storage again, like this, and unlimited circulation, household light fixtures just can be made to realize automatic electric power storage on daytime, night automatic illuminating, daytime automatic distinguishing, greatly reduce manpower and materials, and such design, can more electric energy be saved.
Further, the keyboard circuit be connected with the P3 mouth of intelligent controller, for self-inspection and the mode of operation optimum configurations of realizing circuit.
Keyboard circuit arranges F1/F2 button and realizes distinct program flow process.Refer to Fig. 5, intelligent controller detects whether be in self-inspection state under F1 bonded state, if (Y) then returns to interface, (N) then detects and whether is arranging state if not, call and subprogram is set, otherwise time delay 2 seconds, within 2 second time, F1 key is still pressed, and arranges mode bit, otherwise returns.
Intelligent controller is under F2 bonded state, and whether detect in self-inspection state, being return, otherwise judging whether arranging state, is that currency adds 1, otherwise in the 2 second time of time delay, F2 key still presses execution self-check program.
For convenience of be DC load as electric power supplies such as LED, be also connected with DC circuit in intelligent controller one end and be connected with DC load.As shown in Figure 6, because LED uses direct current, and illuminating effect is better, does not need carry out interchange conversion thus saved energy resource consumption.Even if also can continue when inverter damages to use solar panel to provide power supply for LED.
The utility model provides a kind of family solar LED illuminating system, is protected lighting circuit by hardware and software, prevents from causing accident to occur because of circuit question, makes LED illumination System obtain better protection.
Should be understood that; application of the present utility model is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert; such as, all these improve and convert the protection range that all should belong to the utility model claims.
