The specific embodiment
The bimodulus anti-theft system of electromotor car of the employing microcomputerized control that the utility model proposes, the structure drawings and Examples are described in detail as follows:
Composition of the present utility model as shown in Figure 1, this system comprises: microcomputer controller, vibration sensor, electric door lock identification/control circuit, power amplifier, voice broadcast chip and loud speaker only; Wherein, microcomputer controller respectively with vibration sensor, electric door lock identification/control circuit, voice broadcast chip link to each other, power amplifier links to each other with loud speaker with microcomputer controller, voice broadcast chip respectively; Microcomputer controller also links to each other with the power supply and the entire car controller of battery-driven car respectively, and links to each other with motor phase line signal with the signal of setting up defences respectively; Electric door lock identification/control circuit also links to each other with the entire car controller of battery-driven car.
The utility model can be placed on any position that can install of battery-driven car, comprises in the battery case.
Principle of work of the present utility model:
Electric door lock is the switch that power supply is provided to electric vehicle motor, entire car controller.After the electric door lock closure, electric vehicle motor, entire car controller just can have been worked.Electric door lock can be a key switch, also can be to be subjected to monolithic processor controlled relay, and this part device all belongs to the device of battery-driven car itself.
After the electric door lock closure, electric door lock identification/control circuit is received this signal by the electric door lock interface, handle through microcomputer controller identification, the output corresponding signal is given the voice broadcast chip, the sound signal of sending promotes loud speaker after power amplifier amplifies, loud speaker sends start voice suggestion sound: " welcome to use the xx battery-driven car, it is happy happily to wish you ", at this moment you just can relieved use battery-driven cars.After electric door lock disconnected, loud speaker sent prompt tone: " thanks use, would you please with well you carry-on articles, note antitheft.”
The user can carry out the associative operation of antitheft setting as required, as leaves and be provided with before the car antitheftly, removes antitheft setting etc. before using car.Microcomputer controller makes the voice broadcast chip send corresponding voice suggestion signal by loud speaker according to user's operating order, sends voice suggestion to power amplifier, informs user's content of operation, as " setting up defences ", " set up defences and remove " etc.Operation can be passed through key switch, and the equipment on the battery-driven car car loads such as horn punch also can be set by remote controller.
Only under the state of setting up defences, microcomputer controller could receive the vibration signal of vibration detecting sensor and the next voltage signal of motor phase line transmission of battery-driven car; When microcomputer controller finds that vibration detecting sensor has detected vibration signal, after perhaps the motor phase line has transmitted voltage signal after motor rotates, microcomputer controller can send command adapted thereto and give speech chip, speech chip amplifies through power amplifier, send alarm voice by loud speaker, behind alarm voices such as " not bumping me ", " stopping thief ", microcomputer controller can send multiple frequency alarm sound signal, after power amplifier amplified, loud speaker sent chimes of doom.
Sending alarm sound simultaneously, microcomputer controller is opened the relay that is connected between battery supply and the electric door lock by electric door lock identification/control circuit, power supply is provided promptly for the electric vehicle motor controller; Microcomputer controller provides a lock motor signal for this car entire car controller simultaneously.If this moment, motor continued to be pushed, the electric vehicle motor controller is then made the action of corresponding lock motor.
When not setting up defences, microcomputer controller is not accepted vibration detecting sensor and the next signal of motor phase line transmission, even this moment, battery-driven car had vibrations or motor to be pushed, does not have the sound and the action of warning yet.
The embodiment and the function declaration of each parts of the present utility model are as follows:
Microcomputer controller (model :), speech chip (model: AK040) and vibration sensor (model: SW-420) be device common on the market as auspicious Sa R8C/11; Speech chip is recorded the voice that needs are reported in advance according to customer requirement, as " welcome using the xx battery-driven car; it is happy happily to wish you ", " thanks use, would you please with well you carry-on articles, note antitheft ", " setting up defences ", " set up defences and remove ", " not bumping me ", " stopping thief " wait and point out and alarm voice.
Electric door lock identification/control circuit example structure of the present utility model as shown in Figure 2, the working process of this circuit is: the electric door lock identification circuit adopts resistance R 19, and the R20 dividing potential drop provides electric door lock signal LOCK_MCU to microcomputer controller.When the battery-driven car electric door lock was closed, this electric resistance partial pressure provided an about 5V signal to micro computer; When the battery-driven car electric door lock disconnected, this input port voltage was 0V.If microcomputer controller provides a 5V signal to aerotron Q4 (adopting 2N5551), then relay (SRA24VDC) is opened, and (BATTERY+) passes to electric door lock anode voltage.Give external electric vehicle motor controller by electric door lock, so just can make it carry out the work of anti-theft column lock motor.
Power amplifier example structure of the present utility model as shown in Figure 3, microcomputer controller can directly produce the multiple audio alarm sound, microcomputer controller can be controlled speech chip and produce true man's voice.The both can give transistor drive circuit by capacitive transmission.Three aerotrons form complementary push-pull and amplify, and export to loud speaker and carry out work.The circuit working principle is as follows.After true man's voice send from speech chip, after capacitor C T4 filtering, pass to resistance R 13 and R14 and act on the CT5 positive pole, the alarm sound that microcomputer controller produces then acts directly on the CT5 positive pole.The CT5 isolated DC, and sound signal is passed to aerotron Q3 (2N5551).VOICE_CTRL is a low level when circuit working, and this moment, aerotron Q4 was an off state.At this moment, sound signal is passed to aerotron Q3 (2N5551).Q3 passes to this signal in the push-pull power amplifier circuit of being made up of resistance R 11, aerotron Q1 (2SC2383), aerotron Q2 (2N5401) and capacitor C T3.This power amplifier drives loud speaker HORN (32 Europe/1W) pronunciation.Aerotron Q4 act as the control sound switch.When VOICE_CTRL was high level, aerotron Q4 opened, and the base stage of aerotron Q3 is moved to low level.This moment, aerotron Q3 did not work, and the power amplifier of back has not been worked yet.
This circuit has quiescent current little, fidelity height, the characteristics such as low in energy consumption. Be fit to very much the application of native system.
