Different charging strategies ensures system work；Different charging strategies is taken according to the practical battery condition of battery pack；Work as battery
Single-unit battery core voltage less than 2.7V/CELL, since system operating current is larger, battery core remaining capacity is not enough to maintenance system
Normal work directly to system power supply and is charged the battery at this time by the voltage for base station of charging, and concrete operating principle is as follows：
System detectio cell voltage during charging station when machine is linked into, if voltage is less than 2.7V/CELL, at this point, MCU is sent out
BD_EN, BT_ctr the control signal gone out is all for low level, TF14 MOS conductings, charging base station to system power supply, meanwhile, TF10
MOS ends, and battery is prevented to avoid battery over-discharge, the work of each section circuit is as follows to system power supply：Battery voltage detection
Circuit：When system works, the branch pressure voltage of AD input pin detection resistances R142, R146, R147 of MCU are calculated through over-sampling
The voltage value of battery, and compared with the charge threshold of software setting, to control charging modes；
The voltage that microcontroller micro control unit chip MCU is sampled：
V=(R146//R147) * (R142+R146//R147) * Vbattery
The effect of wherein TF15 metal-oxide-semiconductor field effect transistors is as follows：
When system is under normal power supply state, the G poles of MOS are powered by 12V voltages to G poles, and G pole tensions are：
VG-S=R127/ (R126+R127) * 12V
This voltage ensures the reliable conducting of TF15 pipes, and battery voltage sampling circuit work, when system cut-off, TF15 is because of G, S
Terminal voltage is ended for zero, and battery voltage sampling circuit disconnects, and preventing battery, reducing machine does not make by this circuit discharging
Electric quantity consumption in the case of,
When machine be linked into the case of system cut-off charging base station, at this time because the BT_ctr signals of MCU be low level,
Triode Q28 ends, and the voltage at the B-E ends of triode Q27 is：
VB-E=VCIN+*R212/ (R210+R212),
This voltage value is more than the on state threshold voltage of triode, and triode Q27 is connected, at this time the G-S ends of TF14 metal-oxide-semiconductors
Voltage is：
VG-S=VCIN* (1-R211/ (R209+R211))

BD_EN is switched to high level by low level, and charged state switches as described below：
When being switched to high level by low level because of BT_ctr signals, triode Q28 is led by cut-off state switched conductive state
The base voltage of triode Q27 is caused to be reduced to no-voltage and end, TF14 ends therewith,
Base station is disconnected to system power supply channel,
While BT_ctr signals are switched to high level by low level, BD_EN signals are also switched to high electricity by low level
Flat, triode Q16 is switched to conducting state by cut-off state, and the voltage drop at R138 resistance both ends is more than the G-S electric conductions of TF10
Pressure, TF10 MOS are connected therewith, at this point, while base station supplying channels disconnect, by battery to system power supply,
The effect of D23A diodes：In the other working conditions of system, the state in addition to charging, to prevent cell voltage
CIN+ signal ends are added to by the body diode of TF14, system is made to be judged as entering charged state and maloperation, adds an obstruction two
Pole pipe；
The effect of D23 diodes：In charged state, charging voltage is prevented to be filled by the body diode of TF10 to battery
Electricity；
This system uses intelligentized charging management system, and the data in multiple charge data detections and charging process are surveyed
Amount, provides multiple protection functions, to ensure charging safety；
Chip MCU is by detecting the size and the charge cutoff voltage and electric current according to setting that cell voltage determines charging
Value, decision when terminate charging, with ensure charging safety and raising battery service life,
MCU controls the size of charging current by controlling the level condition of ChrgEn1, ChrgEN2 signal,
When cell voltage is less than 2.7V/CELL when MCU is detected, charged the battery using low current, at this point,
ChrgEn1 signals are low level, meanwhile, ChrgEN2 signals are high level, and triode Q20 is connected, and triode Q19 is led therewith
Logical, base station voltage is charged the battery by resistance R164, R164A, R164B, Q19,
The effect of resistance R164, R164A, R164B are as follows：
Metering function is played, charging current is：
IChrg=(VCIN+-Vbattery)/(R164+R164A+R164B)
It avoids cell voltage too low, by base station voltage pull-down, leads to system cisco unity malfunction；
When cell voltage is higher than 2.7V/CELL when MCU is detected, charged the battery using high current, at this point,
ChrgEn1 signals are switched to high level, meanwhile, ChrgEN2 signals are switched to low level, triode Q21 conductings, metal-oxide-semiconductor TF12
Be connected therewith, base station voltage is charged the battery by resistance TF12 metal-oxide-semiconductors, charging current by base station charger current size Lai
It determines, R176, R181 are current sampling resistor, when the voltage that charging current flows through the generation of this resistance is more than MCU setting charging thresholds
During threshold voltage, MCU thinks the overcurrent that charges, and stops charging immediately；
Charge cutoff condition：
When battery stagnation pressure is more than 4.15V/CELL or charging current is less than 200mA, stops charging, battery is avoided to occur
It overcharges；System power supply circuit：
This system power-supply service provided by the way of Switching Power Supply and linear stabilized power supply combination 12V needed for system,
5V, 3.3V voltage, specific works are described as follows：
Cell voltage or base station supply voltage are added in the input pin 1 of Switching Power Supply transformation chip, when switch control pin 5
During for low level, the metal-oxide-semiconductor between control chip interior connection pin 1 and pin 2 is on off state, and metal-oxide-semiconductor is each
The turn-on time of a switch periods feeds back to the feedback voltage at 4 end of pin and the mistake of built-in reference voltage depending on output voltage
The size of difference,
MOS conducting states are put in the chip, and input voltage provides energy, while inductance L1 by inductance L1 to output+12V
With capacitance C64 during this period also can storing up electricity energy,
It when MOS is disconnected, can release in electric energy of the upper turn-on cycle memory storage on inductance L1, be supplied to load
Electricity, diode D21 provide current loop to inductance L1, and when energy reduces on L1, C64 supplements provide voltage, maintain output
Voltage+12V is constant；
The operation principle of built-in switch pipe is as described below：
When loading increasing, output voltage reduces, while the voltage of feedback pin 4 decreases, the base with chip interior
The error amount of quasi- voltage increases, and as a result lengthens the turn-on time of built-in MOS, and more electricity increase output terminal, makes output electric
The nearly setting pressure of crimping, maintains output voltage stabilization；
Similarly, when output loading reduces, output voltage rises, therefore feedback voltage reduces with reference voltage error, leads
Built-in MOS switch pipe turn-on time is caused to reduce, reduces the electricity that feeder ear is supplied to load end, output is made to fall after rise to setting
Voltage value, more than because of the variation of load, cause output voltage and set the error amount of voltage value, output voltage is made to remain dynamic
Input voltage because Switching Power Supply is operated on off state, is directly transformed to voltage needed for system by the stationary value of state balance,
Cancel the energy expenditure of linear power supply input and output voltage difference, therefore, with efficient, simultaneity factor calorific value is small, provides and is
System functional reliability,
U18, U16 are three terminal regulator, provide 5V, 3.3V operating voltage needed for system；
Motor control part principle：
Control principle drawing is as follows：
When collision alarm is sent to MCU by Hall sensor, MCU will control the BLADE_DIR's in motor operation direction
Signal is switched to high level by low level, after the processing of following negative circuit, generates low level BLADE_P7 signals to electricity
Machine driving chip U13, motor switch inverted status by rotating forward, and machine performs fall back action, and left and right movable motor has
Identical function；
The electromechanical machine speed control circuit schematic diagram of Figure 20 intelligence gardens work is please referred to below：
Motor speed control principle：
Under different working conditions, motor operation speed also differs machine, it is therefore desirable to feed back the operation speed of motor
It spends signal and drives core U13 to motor, this system design uses dedicated motor speed detection chip, to generate motor speed control
Feedback voltage needed for system, without expensive tachometer, U12, you can realize this function,
Concrete operating principle is as described below：
It is positive or negative to be motor driven Hall sensor output signal generations of the chip U13 as the decoding of electronics rotor position
Saltus step can be such that U12 one amplitude of generation and the pulse of duration, parameter is determined by non-essential resistance R101, C48,
Output pulse at the pin 5 of U12 is integrated by the error amplifier of U13, to generate a DC level, the level and motor
Speed is directly proportional, this velocity feedback voltage establishes PWM datums, and be closed into feedback control loop at the pin 13 of U13, defeated
Go out to drive the control signal of MOS, meanwhile, the PWM reference voltages at U13 pins 13 are fed back into MCU with analog-digital conversion function
Pin, so that MCU learns motor actual motion speed, and control is adjusted according to the difference of actual motion velocity amplitude and setting value
Voltage processed,
Interlock circuit is described as follows：
RMOT_DAC is that the target velocity of MCU outputs controls the voltage value, (amplification factor=1+ after operational amplifier amplifies
R5/R12), send to the pin 11 of right movable motor driving chip, draw the difference of target velocity voltage and actual speed voltage
After the amplification of chip interior error amplifier, the reference voltage signal RMOT_P6 that above-mentioned PWM is adjusted is exported at pin 13.

When the single-unit battery core voltage of battery is less than 2.7V/CELL, since system operating current is larger, battery core remaining capacity
It is not enough to maintain system worked well,
It directly to system power supply and is charged the battery by the voltage for base station of charging at this time, concrete operating principle is as follows：
Please refer to Figure 14 intelligence gardens working machine charge management circuit schematic diagram：
System detectio cell voltage during charging station when machine is linked into, if voltage is less than 2.7V/CELL, this
When, BD_EN, BT_ctr that MCU is sent out control signal are all low level, TF14 MOS conductings, charging base station to system power supply,
Meanwhile TF10 MOS end, and battery is prevented to avoid battery over-discharge, the work of each section circuit is as follows to system power supply：
Battery voltage detection circuit：
When system works, the branch pressure voltage of AD input pin detection resistances R142, R146, R147 of MCU, through over-sampling meter
The voltage value of battery is calculated, and compared with the charge threshold of software setting, to control charging modes；
The voltage that MCU is sampled：V=(R146//R147) * (R142+R146//R147) * Vbattery
The effect of wherein TF15 metal-oxide-semiconductors is as follows：
When system is under normal power supply state, the G poles of MOS are powered by 12V voltages to G poles, and G pole tensions are：
VG-S=R127/ (R126+R127) * 12V
This voltage ensures the reliable conducting of TF15 pipes, and battery voltage sampling circuit work, when system cut-off, TF15 is because of G, S
Terminal voltage is ended for zero, and battery voltage sampling circuit disconnects, and preventing battery, reducing machine does not make by this circuit discharging
Electric quantity consumption in the case of；
When machine be linked into the case of system cut-off charging base station, at this time because the BT_ctr signals of MCU be low level,
Triode Q28 ends, and the voltage at the B-E ends of triode Q27 is：
VB-E=VCIN+*R212/ (R210+R212),
This voltage value is more than the on state threshold voltage of triode, and triode Q27 is connected, at this time the G-S ends of TF14 metal-oxide-semiconductors
Voltage is：
VG-S=VCIN* (1-R211/ (R209+R211))
Therefore TF14 is connected, base station voltage VCIN+, to system power supply, system Auto Power On, and is detected whether by TF14

IChrg=(VCIN+-Vbattery)/(R164+R164A+R164B)
It avoids cell voltage too low, by base station voltage pull-down, leads to system cisco unity malfunction；
When cell voltage is higher than 2.7V/CELL when MCU is detected, charged the battery using high current, at this point,
ChrgEn1 signals are switched to high level, meanwhile, ChrgEN2 signals are switched to low level, triode Q21 conductings, metal-oxide-semiconductor TF12
Be connected therewith, base station voltage is charged the battery by resistance TF12 metal-oxide-semiconductors, charging current by base station charger current size Lai

The nearly setting pressure of crimping, maintains output voltage stabilization；
Similarly, when output loading reduces, output voltage rises, therefore feedback voltage reduces with reference voltage error, leads
Built-in MOS switch pipe turn-on time is caused to reduce, reduces the electricity that feeder ear is supplied to load end, output is made to fall after rise to setting
Voltage value, more than because of the variation of load, cause output voltage and set the error amount of voltage value, output voltage is made to remain dynamic
Input voltage because Switching Power Supply is operated on off state, is directly transformed to voltage needed for system by the stationary value of state balance,
Cancel the energy expenditure of linear power supply input and output voltage difference, therefore, with efficient, simultaneity factor calorific value is small, provides and is

Border battery condition takes different charging strategies, ensures system work；Different fill is taken according to the practical battery condition of battery pack
Electric strategy；When the single-unit battery core voltage of battery is less than 2.7V/CELL, since system operating current is larger, battery core remaining capacity is not
It is enough to maintain system worked well, directly to system power supply and is charged the battery by the voltage for base station of charging at this time, specific work
It is as follows to make principle：System detectio cell voltage during charging station when machine is linked into, if voltage is less than 2.7V/CELL,
At this point, BD_EN, BT_ctr control signal that MCU is sent out is all for low level, TF14 MOS conductings, charging base station to system power supply,
Meanwhile TF10 MOS end, and battery is prevented to avoid battery over-discharge, the work of each section circuit is as follows to system power supply：Battery
Voltage detecting circuit：When system works, the branch pressure voltage of AD input pin detection resistances R142, R146, R147 of MCU pass through
Sampling calculates the voltage value of battery, and compared with the charge threshold of software setting, to control charging modes；
The voltage that microcontroller micro control unit chip MCU is sampled：
V=(R146//R147) * (R142+R146//R147) * Vbattery
The effect of wherein TF15 metal-oxide-semiconductor field effect transistors is as follows：
When system is under normal power supply state, the G poles of MOS are powered by 12V voltages to G poles, and G pole tensions are：
VG-S=R127/ (R126+R127) * 12V
This voltage ensures the reliable conducting of TF15 pipes, and battery voltage sampling circuit work, when system cut-off, TF15 is because of G, S end electricity
Pressure is ended for zero, and battery voltage sampling circuit disconnects, and prevents battery by this circuit discharging, reduce machine without using feelings

TF10 MOS are connected therewith, at this point, while base station supplying channels disconnect, by battery to system power supply,
The effect of D23A diodes：In the other working conditions of system, the state in addition to charging, to prevent cell voltage from passing through
The body diode of TF14 is added to CIN+ signal ends, and system is made to be judged as entering charged state and maloperation, adds a blocking diode；
The effect of D23 diodes：In charged state, charging voltage is prevented to charge the battery by the body diode of TF10；
This system uses intelligentized charging management system, and the DATA REASONING in multiple charge data detections and charging process carries
For multiple protection functions, to ensure charging safety；

IChrg=(VCIN+-Vbattery)/(R164+R164A+R164B)
It avoids cell voltage too low, by base station voltage pull-down, leads to system cisco unity malfunction；
It when cell voltage is higher than 2.7V/CELL when MCU is detected, is charged the battery using high current, at this point, ChrgEn1 believes
Number high level is switched to, meanwhile, ChrgEN2 signals are switched to low level, triode Q21 conductings, and metal-oxide-semiconductor TF12 is connected therewith,
Base station voltage is charged the battery by resistance TF12 metal-oxide-semiconductors, and charging current is determined by base station charger current size,
R176, R181 are current sampling resistor, when the voltage that charging current flows through the generation of this resistance is more than MCU setting charge thresholds
During voltage, MCU thinks the overcurrent that charges, and stops charging immediately；

Nearly setting pressure, maintains output voltage stabilization；
Similarly, when output loading reduces, output voltage rises, therefore feedback voltage reduces with reference voltage error, causes interior
The MOS switch pipe turn-on time put reduces, and reduces the electricity that feeder ear is supplied to load end, output is made to fall after rise to the voltage of setting
Value, more than because of the variation of load, cause output voltage and set the error amount of voltage value, output voltage is made to maintain dynamic equilibrium
Input voltage because Switching Power Supply is operated on off state, is directly transformed to voltage needed for system, cancels linear electricity by stationary value
The energy expenditure of source input and output voltage difference, therefore, have it is efficient, simultaneity factor calorific value is small, provides system reliable operation

Rotation stop is moved, and overcurrent protection set-point is：
Icurrent=0.1* (R117+R119)/(R118*R119)
When overcurrent events occur, the output of driving chip Fault Output pins is low level, by motor drive signal
OutputEnable signals drag down, and motor shuts down, and avoid machine loading electric current excessive and electronic device damage occurs, when
When Fault Output are low level, the B-E terminal voltages of triode Q24 are also reduced to zero, and cut-off state is switched to by conducting state,
