Description
Technical field
The present invention relates to robot field, more particularly to a kind of energy-conservation switching circuit for the active and standby battery of robot.
Background technology
The machine cruised artificially guarantees continuously to work, and is typically powered using active and standby battery powered mode to robot, main
Battery can be changed, i.e.,：The main battery for the electricity that runs low is changed, changes another piece of fully charged main battery.By standby during replacing
Battery powered.Traditional switching circuit is switched by Schottky diode, although circuit is simple, Schottky diode has pressure
Drop, power consumption are more.
The content of the invention
In order to overcome disadvantages mentioned above, the invention provides a kind of energy-conservation switching circuit for the active and standby battery of robot.
The used to achieve the above object technical scheme of the present invention is：
A kind of energy-conservation switching circuit for the active and standby battery of robot, by NMOS tube, single-chip microcomputer, chip LTC4359 and its supporting
Resistance, electric capacity, diode composition, it is characterized in that：
The single-chip microcomputer controls positive high voltage diode control chip LTC4359, chip LTC4359 to control NMOS tube both ends again
Forward drop, it is ensured that the smooth electric current transmission of standby battery dead-beat, to substitute traditional Schottky diode；Main battery is direct
Positive high voltage diode control chip LTC4359, chip LTC4359 is controlled to control the forward drop at NMOS tube both ends again, really
The smooth electric current transmission of main battery dead-beat is protected, to substitute traditional Schottky diode；Main battery NMOS tube and standby battery
NMOS tube is carried out or connected again.Due to parasitic diode be present inside NMOS, so by the corresponding of monolithic processor controlled standby battery
Circuit forms back-to-back circuit using two NMOS tubes, avoids reverse leakage caused by NMOS parasitic diodes.
The invention has the advantages that the present invention can save.
Brief description of the drawings
The present invention is further described with implementation below in conjunction with the accompanying drawings.Fig. 1 is the circuit diagram of the present invention.
Embodiment
In Fig. 1, ZD, FD are respectively main battery and secondary cell, and U1 and U2 are that chip LTC4359, U3 are single-chip microcomputers
STM32, Q1, Q2, Q3 are NMOS tubes, and Q4 is NPN triode；R1 and R2 composition divider resistances；R3 is current-limiting resistance；R4 and R5 are
Chip LTC4359 build-out resistor；R6 and R7 composition divider resistances；Diode D1 and D2, D3 and D4 are protection device, protect core
Piece LTC4359；D5 and D6 is 12V voltage-regulator diodes, for protecting NMOS tube；C1 and C2 is filter capacitor.U1 and Q2 and U2
Circuit with Q1, Q3 composition equivalent to Schottky diode, unlike, Schottky diode has a pressure drop, and power consumption is more.And by
The circuit of LTC4359 and NMOS compositions, conducting resistance is extremely low, and power consumption is small.The chip LTC4359 pin of Enable Pin 5, when connecing high level
Chip operation, do not work when connecing low level, disconnected equivalent to circuit.
During robot normal work, powered, the pin of U3 single-chip microcomputers 1 output high level, triode Q4 conductings, made by main battery ZD
5 pin for obtaining U2 drag down, and U2 does not work.When robot needs to change battery, single-chip microcomputer output low level, triode Q4 cut-offs, U2
5th pin voltage is high level, and U2 work, now robot power supply is by main battery or standby battery powered（By the high electricity of cell voltage
Pond powers）, when main battery is removed, robot is by standby battery powered.After robot finishes changing battery, now, single-chip microcomputer is defeated
Go out high level, standby battery is disconnected, and robot is powered by main battery.Due to parasitic diode inside NMOS be present, institute is in case battery
Related circuit form back-to-back circuits using two NMOS tubes Q1, Q3, avoid and reversely leaked caused by NMOS parasitic diodes
Electricity.
The above described is only a preferred embodiment of the present invention, not making any formal limitation to the present invention, appoint
How without departing from the present invention program content, any simple modification made according to technical spirit of the invention to above example, etc.
With change and modification, in the range of still falling within technical solution of the present invention.
