The operation principle of the present invention is: about 220V alternating voltage is carried out blood pressure lowering by isolating transformer, about it is down to exchange 18V to 20V, then pass through rectifier bridge and be rectified into direct current, smooth DC voltage is become after voltage after rectification electric capacity after filtering, its value is approximately 24V～26V, need to be followed by, at rectifier bridge, the pipe that insures, so can effectively prevent because circuit is burnt in short circuit, the DC voltage of rectifier filter output is as the voltage source of whole system, one is provide power supply to constant pressure and constant streaming charging circuit, two is provide power supply to system power supply circuit, the buck circuit that constant pressure and constant streaming charging circuit is mainly made up of Control of Voltage cake core TL494, original buck type topological circuit is reequiped, defining can constant voltage, the charging circuit that constant current mode arbitrarily switches.
nullAfter the second electric capacity C2 in constant voltage constant current charging circuit and connect the voltage sample feedback network being made up of the first resistance R1 and the eight resistance R8，First resistance R1 is that its resistance of slide rheostat is adjustable，The size of sample voltage value just can be adjusted by regulating this resistance，Accessed 1 pin of TL494 by the second relay K 2 from the voltage of voltage sample node Sample_Voltage sampling，1 pin of TL494 is the input in the same direction of its builtin voltage comparator，The DA passage corresponding voltage of output being controlled system by MK60 just can control the charging circuit corresponding magnitude of voltage of output to 2 pins of TL494，Owing to 2 pins and 5 pins of the second relay K 2 are in connection status when not switching，So charging circuit works in constant voltage mode when K2 does not switch，At this moment only need to control system by MK60 just accurately can control the output voltage of charging circuit in real time，9th resistance R9 uses as current sampling resistor，For improving the precision of current sample and reducing the power attenuation in sampling process，Its must use constantan wire resistance and resistance less be about 0.5 Europe，After output port P2 connects load，Have electric current and flow through R9 thus producing pressure drop on Sample_Current network node，Owing to Sample_Current network node is that 4 pins with K2 are connected，So current sample feedback network can not access TL494 when K2 does not switch，Charging circuit is operated in constant current mode，When K2 switches，Current sample feedback network accesses TL494 will necessarily the connection of off voltage sampling feedback network and TL494，As long as so while K2 switching, the magnitude of voltage of MK60 control system amendment DA passage output just can control the corresponding current value of charging circuit constant output，Based on above-mentioned，Control charging circuit is operated in constant current or constant voltage mode is to be realized by switching K2，How much during constant current (constant voltage) pattern, the current value (magnitude of voltage) of output is the magnitude of voltage decision being controlled the output of system DA passage by MK60 if being specially，Due to built-in 16 the DA output channels of MK60 single-chip microcomputer，So the voltage that energy output accuracy is significantly high，Thus realizing the accurate control of constant voltage output valve or constant current output value，The switching of K2 is by mean of MK60 and controls what the system I/O control signal exported completed，The I/O of control system accesses the base stage of third transistor Q3，The Q3 conducting when I/O exports high level，The colelctor electrode of Q3 has electric current to flow through thus causing that relay K 2 switches，2 pins of K2 and 5 pins disconnect、2 pins and 4 pins Guan Bi，The Q3 cut-off when I/O output low level，The colelctor electrode of Q3 does not have electric current to flow through thus causing that K2 switches back into original state again.
nullThe switching of the first relay K 1 be also by mean of MK60 single-chip microcomputer the same as K2 completes，K1 accesses the major loop of charging circuit，When circuit is without exception, 2 pins of K1 and 5 pins connect normal circuit operation，If circuit can be detected by the sensor of current sample network or external Hall element etc owing to electric current that suddenly-applied short circuit flows through increases us suddenly，The data detected can pass to MK60 control system and process，Control system sends control signal by I/O and switches K1 disconnecting circuit in time，Thus realizing the short-circuit protection to charging circuit，The UART communication module arranged controls end for PC and carries out data communication with MK60 control system，We just can control system by UART bus transfer to MK60 in the parameter of long-range PC control end input pulsed fast charge，MK60 controls the magnitude of voltage that system just can receive according to 2 pins of K2 switching time and TL494 that the supplemental characteristic received controls charging circuit，So we just can be arranged or revise the mode of pulsed fast charge in real-time online ground.
After material object, we are charged to the accumulator of rated voltage 12V to the present invention, and the pulsed fast charge mode adopted is first current value constant-current charge 30 seconds with 1.34A；Again with the current value constant-current charge 20 seconds of 0.33A；Finally carry out constant-voltage charge 60 seconds with fixing magnitude of voltage, practice effect proves that it can effectively and rapidly complete the charging to accumulator, owing to accumulator charged voltage value constantly (can reach 13V in full electricity situation in change, about 11V is only had during electricity wretched insufficiency), so needing constantly to revise the magnitude of voltage of constant-voltage charge to optimize charging effect by single-chip microcomputer.
Above in conjunction with accompanying drawing, the present invention is exemplarily described; the obvious present invention implements and is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that the design of the method for the present invention carries out with technical scheme; or the not improved design by the present invention and technical scheme directly apply to other occasion, all within protection scope of the present invention.Protection scope of the present invention should be as the criterion with claims protection defined.
