Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a circuit structure block diagram of the present utility model;
Fig. 2 is the utility model circuit diagram.
Embodiment
A kind of solar street lamp controller as shown in Figure 1 and Figure 2, comprises solar panel 1, CPU control unit 5 and storage battery 3.CPU control unit 5 is selected the PIC16F716 single-chip microcomputer for use, and the PIC single-chip microcomputer is a kind of 8 single-chip microcomputers that U.S. MICROCHIP (little core) company releases, and its Hardware Design is simple and direct, and Instruction System Design is concise, adopts reduced instruction set computer and Harvard's dual-bus structure.PIC16C716 has the program counter of one 13 bit wide, the program's memory space of maximum addressable 8K * 14, and 13 I/O pins, 48 A/D passages, memory capacity is 2K*14.But be a kind of FLASH chip of overprogram, with low cost, dependable performance, erasable removing repeated the programming number of times greater than 100,000 times, and the still a large amount of productions of pilot development are all very flexible.This controller also comprises charging driver element T1 and the discharge driver element T2 that is made of metal-oxide-semiconductor respectively, solar cell 1 links to each other with storage battery 3 by charging driver element T1, storage battery 3 links to each other with load 2 by discharge driver element T2, and charging driver element T1 all links to each other with the control end of CPU control unit 5 with discharge driver element T2.
As shown in Figure 2, the utility model operation principle is as follows:
Charge and discharge protecting: adopt Schottky STP2045 to prevent that storage battery 3 is to solar cell 1 reverse charging.When storage battery 3 voltages are under the normal condition, solar cell 1 voltage is higher than 7 volts, and it is low level that monolithic processor controlled charging drives T1, optocoupler OP1A signal end is not luminous, induction end is ended, high level, metal-oxide-semiconductor T1 conducting, it is low level that monolithic processor controlled discharge drives T2, optocoupler OP1A1 induction end is ended, high level, and metal-oxide-semiconductor T2 ends, this moment, solar cell charged to storage battery 3, but load output is by (light-operated); When solar cell 1 has high level, when storage battery 3 voltages reached 13.6V, it was the pulsewidth high level that monolithic processor controlled charging drives T1, and metal-oxide-semiconductor T1 intermittently ends, and was in floating charge state this moment; When storage battery 3 voltages be higher than setting overcharge a some 14.4V time, it is high level that monolithic processor controlled charging drives T1, the conducting of optocoupler induction end, low level, metal-oxide-semiconductor T1 ends, storage battery 3 over-charge protectives; When storage battery 3 voltages dropped to 13.2V, it was low level that the single-chip microcomputer charging drives T1, and the optocoupler induction end is ended, high level, and metal-oxide-semiconductor T1 conducting reverts to normal charging condition.When storage battery 3 voltages are under the normal condition, and solar cell 1 voltage is lower than 2 volts, and it is high level that monolithic processor controlled discharge drives T2, the conducting of optocoupler OP1A1 induction end, and low level, metal-oxide-semiconductor T2 conducting, this moment, load output was normal; And solar cell 1 voltage is higher than 7 volts, and it is low level that monolithic processor controlled discharge drives T2, and optocoupler OP1A1 induction end is ended, high level, metal-oxide-semiconductor T2 ends, and load output this moment ends, when the mistake that is lower than setting when storage battery 3 voltages is put a some 11.2V, solar cell 1 voltage is lower than 2 volts, it is low level that monolithic processor controlled discharge drives T2, and optocoupler OP1A1 induction end is ended high level, metal-oxide-semiconductor T2 ends, load this moment no-output; When storage battery 3 voltages reached 13.2V, it was high level that monolithic processor controlled discharge drives T2, the conducting of optocoupler OP1A1 induction end, and low level, metal-oxide-semiconductor T2 conducting, this moment, load output recovered normal.
Short circuit overload protection: when being short-circuited or during load over insurance rated value, protecting by burning protective tube.
Protection to error-polarity connection: standard practice is to adopt backward diode IN5408, and anti-stop polarity connects instead.In case battery polar connects instead, directly burns protective tube.After the correction, connect insurance again, all recover normal again.
Temperature-compensating: be in series with thermistor 6 on CPU control unit 5 and the circuit that storage battery 3 links to each other.Because the capacity of storage battery 3 changes with variation of temperature, temperature raises, and the capacity of storage battery 3 will increase; Temperature reduces, and the capacity of storage battery 3 will reduce.If charging current remains unchanged, corresponding rate of charge will change, and different charge rate correspondences different overcharging a little, therefore, adopt temperature-compensating that storage battery 3 is protected.Single-chip microcomputer PIC16F716 detects Current Temperatures in real time by the sample temperature parameter, carries out temperature-compensating.The NTC thermistor of 10K is used in temperature-compensating.
