Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without creative efforts belong to the scope of protection of the invention.
The port that B+, B- are denoted as on controller as described in Figure 1 is inputted as battery.Access battery nominal voltage be
24VDC.Battery input polarized is protected and B+ is directly connected with the contact of relay.After relay is attracted, battery just meeting
It powers to circuit.
Key switch inputs the power unit for being attached directly to controller.When key switch input injecting voltage (i.e. B+)
Afterwards, power unit is activated, and microcontroller and its related circuit can be given to power.Microcontroller monitors the state of key switch always.
If key switch is turned off in vehicular motion, vehicle still can stop and then brake under the control of the controller
Electromagnetic brake.
The most common governor of vehicle for selecting mobility scooter for old people controller is exactly tri- line potentiometers of 5k Ω, and the three of potentiometer
Root line is respectively connected to PotHi, PotWiper and PotLo.Speed-regulating signal is taken from the voltage on PotWiper, and reference voltage is
PotLo.Any line occurs that short circuit occurs between open circuit or line and line in three lines, will not all cause the out of control of vehicle.Pass through volume
Journey, also voltage-type governor of the acceptable output voltage range no more than 5V, speed-regulating signal export mobility scooter for old people controller
PotWiper is equally also coupled to, but its reference voltage is B- rather than PotLo.The power supply of voltage-type governor needs client certainly
In addition oneself provides, and the power supply must be with controller altogether.If the signal output area of voltage-type governor is exactly 0~5V,
Because the AD ranges of microcontroller are also 5V in itself, controller can not detect governor whether break or short circuit.
As 1228/1210, mobility scooter for old people controller also provides the input of individual limiter of speed, limit that can be linear
The most high speed of vehicle processed.This limiter of speed need to select the three line potentiometers that nominal value is 100k Ω, be respectively connected to PotHi,
SpeedPot and PotLo.For not filling the vehicle of limiter of speed, mobility scooter for old people controller can also close speed limit by programming
The detection of device.
Vehicle can be designed to gather around there are two types of velocity mode, and one is (outdoor) pattern at a high speed, another is low speed (room
It is interior) pattern.When mode switch does not connect or is off, controller is in 1 state of pattern.After mode switch is closed,
2 state of controller Dietary behavior.Usually pattern 1 be arranged at a high speed and pattern 2 is arranged to low speed.Specific bus connection method refers to figure
1 wiring diagram.
When governor type is single-ended or unipolarity type, this inputs the direct of travel for changing vehicle.When anti-
When being disconnected to input switch, stubborn governor can make vehicle march forward.When reversed input switch is closed, stubborn governor can make vehicle
It draws back.
One charger for being typically used for DME vehicles, plug are all three cores, are B+, B- respectively and forbid exporting.
, it is necessary to which the inhyibit wire of charger exports low level or is directly connected with B- for mobility scooter for old people controller.Work as charging
When device is plugged, the charging of mobility scooter for old people controller forbids input to be pulled low, and controller can forbid motor and electromagnetic brake at this time
Driving.

Degree can be adjusted by 1311 programmable devices.After limitation speed is set to zero, HPD inspections can be also carried out after rate limitation is removed
It surveys.
After input is carried out effectively, controller can discharge electromagnetic brake, forbid driving motor, and keep the motor torque to be
Zero.After the speed that vehicle is carried out is more than setting value, controller can apply brake force to prevent too fast implementation speed to vehicle.
Programmable device and charger have shared a four core sockets.Mobility scooter for old people controller employs ESP (Enhanced
Serial Protocol) agreement come and 1311 hand-held programmers or 1314PC programmable devices communication.With 1228/1210 on use
SP (Serial Protocol) agreement compare, the data exchange time needed for ESP greatly shortens and additionally provides submenu
Function.
The brake coil minimum resistance value that the electromagnetic brake output of mobility scooter for old people controller can drive is 32 Ω.Work as brake cable
When circle open circuit or short circuit, controller can detect and report failure, but brake coil short circuit can cause the driving electricity of controller
Road permanent damages.
It is needed when vehicle rollback or failure simultaneously with sound alarm.This output pin can directly drive buzzing
Device.Since buzzer belongs to perceptual device, so diode D3 is needed to provide continuous current circuit.Resistance R19 strings are in driving triode
Collector in, when buzzer short circuit (output be attached directly to B+ voltages), limiting short-circuit current can be played the role of.
If buzzer short circuit for a long time, then the resistance will fuse as fuse.So driving triode would not be beaten
It is bad, so as to which B+ voltages will not be directly got on microcontroller.In order to ensure that the driving energy bears the buzzer short circuit of certain time,
Mobility scooter for old people controller has selected slightly bigger 0805 to encapsulate.
Status lamp output is used for driving a LED, and one current-limiting resistance of client oneself additional strings is needed to adjust in the LED
The brightness of whole LED.When controller fault-free, this LED long is bright.When controller in the event of failure, this LED can flicker corresponding failure
Code.R19 in being exported with buzzer is similar, this output has also sealed in the same resistance R3, and role is same.
It is 24V DC permanent magnet brush motors with the motor type that mobility scooter for old people controller matches.Client, which needs to select, to close
The motor of suitable power is come the controller of arrange in pairs or groups 45A or 70A.When some problems occur in controller or vehicle, such as battery is unexpected
Broken string, controller can only be braked by short circuit motor at this time.In order to ensure that vehicle can be in on-position, control from beginning to end
The metal-oxide-semiconductor of device cannot damage, and otherwise, the metal-oxide-semiconductor of damage cannot ensure short circuit motor, cannot also ensure that vehicle is in system
Dynamic state, thus for and the motor that matches of controller have the requirement of minimum resistance value.
Controller judges present battery also remains how many electricity by the cell voltage detected.The BDI outputs of microcontroller
Pin output is pwm signal, which is converted into 0~5V after being filtered by 10k Ω resistance (R5) and 0.1uf capacitances (C20)
(corresponding 0~100% battery capacity) DC level.Due to cost considerations, there is no have this level again as 1228/1210
Voltage order one follower but directly export.Although the output impedance of mobility scooter for old people controller has reached 10k Ω, but I
The known client using our controller electrical output signal, be all that electric quantity signal is introduced the defeated of comparator or amplifier
Enter end, so not having apparent attenuation without the battery capacity output voltage of voltage follower.
Mobility scooter for old people controller employs the H bridges (i.e. full-bridge) that can carry out four-quadrant control of standard to drive electricity
Machine.Mobility scooter for old people controller employs unilateral switch not using bilateral switching mode used by 1228 controllers
Pattern.It is compared with bilateral switching mode, the benefit using unilateral switching mode is：1. the ripple of power electrolytic capacitor it is smaller from
And the fever of capacitance is with regard to smaller；2. the detection of current of electric can be carried out using the long conducting resistance for leading to that metal-oxide-semiconductor, so as to
Eliminate inspection leakage resistance；3. (because to give charging bootstrap capacitor, 100%) pulsewidth cannot be to can make under maximum pulse width
Motor turns faster.
The present invention is used for the three-wheel of low-power or four-wheel one-seater electric scooter.Such electric bicycle is led to using object
It is often the crowd that the elderly or walking have obstacle.For the vehicle by 24V battery powereds, motor used is 24V DC brush column motors,
