For accumulator being charged and charging current being controlled；Described anti-theft warning circuit includes sensor
And alarm device, for detecting the state of electric bicycle and reporting to the police, described battery condition monitoring electricity
Road, charge protector and anti-theft warning circuit connect single-chip microcomputer respectively.
In this utility model, each circuit is connected with single chip communication interface, it is achieved data automated communications, uses CAN
Each circuit module is coupled together by bus；Described single-chip microcomputer uses AT89C2051, and each circuit module passes through
Respective processing unit, is controlled sensor；And the information of collection is reached single-chip microcomputer by bus,
After treatment, the functions such as the display and the warning that carry out information.
The rated voltage of electric bike battery is 24V, for avoiding accumulator overdischarge under low-voltage state
The damage being caused accumulator, uses battery condition observation circuit to use accumulator in this utility model
During voltage detect in real time and show, and automatically enter when accumulator is in low voltage operating state
Row sound and light alarm.Such as Fig. 2, described battery condition observation circuit by voltage display between 10 LED region,
Low pressure alarm and 15V manostat composition.Between 10 LED region, display driver is completed by SF3914, when it
4,6 feet between when inputting certain voltage, internal every grade of comparator is driven by voltage levels output low level step by step
Dynamic lumination of light emitting diode.By regulation W3, R1 and W4, R2, SF3914 is made to be in interval voltage instruction
State.W2 inputs driver after making, as attenuator, the high voltage dividing potential drop detected.Wherein 9 feet of SF3914
For controlling display pattern end.When 9 feet connect supply voltage, LED is that wire shows；It is that single-point shows time unsettled.
ICl (SF3914) constitutes comparator, detects the load terminal voltage of LED3.Because this terminal voltage is at LED
Start less with change in voltage during OFF state, circuit uses the method comparing detection, to improve circuit
Detection sensitivity, receive detection signal rear drive piezoelectric buzzer report to the police.
