Accompanying drawing and explanation
Fig. 1 is a circuit block diagram of the present utility model;
Fig. 2 is the circuit diagram of the utility model protection part.
Embodiment
Below in conjunction with accompanying drawing circuit of the present utility model, feature and effect thereof are further specified.
Now it is as follows to itemize embodiment in conjunction with the accompanying drawings: solar panel 1, connect charhing unit 11 and storage battery 2 by connector, charhing unit 11 is made up of fast recovery diode and field effect transistor, its control utmost point is controlled by the P1.6 pin of microprocessor 10, and its output connects storage battery 2, the light power of the detectable environment of solar panel, and then judge daytime and night, when the voltage of solar panel 1 during greater than storage battery 2 voltages, charhing unit 11 has electric current to flow through, and storage battery 2 is in charging.Storage battery 2, connect load driving loop 14 by lead, load driving loop 14 is made up of 2 field effect transistor, field effect transistor is as electronic switch, the output of control loop, its control utmost point is subjected to the P1.7 of microprocessor 10, the control of P3.7 bipod, storage battery 2 provides illuminator required power supply, load 16 be load driving loop 14 with load, it can be DC load with storage battery 2 relevant voltage, as DC power saving lamp, LED lamp, also can drive AC load such as electrodeless lamp, high-pressure sodium lamp by inverter.Microprocessor 10, it is core devices of the present utility model, can monitor storage battery operating state, can discern present light situation, the ruuning situation that can follow the tracks of load, and then according to the different handling procedure of process invocation, for preventing that external interference from causing that equipment operation is not normal, microprocessor 10 has hook procedure auto restore facility out of control.Load driving loop 14, output-controlled in microprocessor, can carry out work according to the time of setting, under-voltage at storage battery, daytime interim, load driving loop 14 stops to export.In load short circuits or when seriously transshipping, load was connected every 10 seconds in load driving loop 6, removed as load short circuits, and then load can operate as normal.The N type enhanced power metal-oxide-semiconductor P60N06 of SGS-THOMSOM company is adopted in load output control.This power tube has low internal resistance (＜0.014 Europe), can bear high operating current (being 60A to the maximum), high breakdown voltage (＞60V) (＞4V) characteristics the results showed under the nominal load of 5A than the low threshold driving voltage, temperature rise is no more than 10 ℃, does not need attached heat sinks.The parameter of load output control circuit is selected to guarantee that 12V and 24V system all can make P60N06 reliably turn on and off, and will notice that simultaneously the gate source voltage of metal-oxide-semiconductor must be limited in the 20V scope, with the protection metal-oxide-semiconductor.Charge in batteries unit 11 according to the battery capacity that sets, utilizes the PWM function of single-chip microcomputer, and controller is regulated the charge in batteries electric current automatically according to the voltage-current characteristic of storage battery different capabilities, obtains the optimal charge effect.With the monomer nominal voltage is that the lead acid accumulator of 12V is an example, when monomer whose voltage 10V-11.5V, just with the charging current of 0.2C to charge in batteries, when monomer whose voltage during at 11.5V-12.5V, just with the charging current of 0.1C to charge in batteries, when monomer whose voltage 12.5V-15V, just with the charging current of 0.05C to charge in batteries.After this fall when safeguarding voltage when voltage, storage battery enters floating charge state, when be lower than safeguard voltage after floating charge close, enter the state that all fills.When battery tension was lower than protection voltage, controller cut out load switch automatically and is not damaged with the protection storage battery.By PWM charging circuit (intelligent three stages charging), can make solar panel performance maximum effect, improve charge efficiency.Load on line detection circuit 15, load and a terminal resistance are in parallel, and this circuit does not work when load is opened.Delivering to the magnitude of voltage of A/D conversion mouthful and load when load disconnection or short circuit does not break down etc. obviously different.Load faulty when microprocessor detects, warning drive circuit 12 can allow buzzer sound.Load overcurrent, short-circuit detecting circuit 9, load overcurrent and short-circuit protection: designed the two-stage protection.The first order has adopted overcurrent that devices such as 0.01 Europe constantan wire and amplifier LM358, comparator LM393 form, A/D conversion that short-circuit detecting circuit cooperates single-chip microcomputer and external interrupt to respond and has realized, this mode of using hardware+software, the output of LM358 is sent P1.7 (A/D conversion) mouthful, as over-current signal identification, when electric current surpasses rated current 20% and keeps more than 30 seconds, confirm as overcurrent; Short circuit current is adjusted and is that 10A, response time are the millisecond order of magnitude.The electrical fuse protection has been adopted in the second level; when the electric current of the electrical fuse of flowing through increases suddenly; temperature rises thereupon; its resistance increases greatly; operating current reduces greatly, reaches the protective circuit purpose, and the response time is a second order of magnitude; overcurrent is cancelled or short circuit recovery back electrical fuse reverts to low-impedance conductor, need not any artificial replacing or maintenance.After system had adopted the two-stage safeguard measure, after reaching the load short circuits experiment of time a few hours, the circuit burnout phenomenon did not still appear in controller.Solved with the traditional insurance silk and can only carry out disposable protection,, compared, also had tangible advantage with the system that needs after the short circuit to open again after hand-reset or the outage in case burn the problem that artificially to change to circuit.Simplify the solar street lamp controller maintenance, improved the security performance of this device.
