Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of power circuit snow-removing device, including single-chip microcomputer, ultrasonic transducer, the first photo-coupler, Second photo-coupler and SPM;
Wherein, single-chip microcomputer uses MSP430G2553 chips, and MSP430G2553 chips can realize PWM ripple signal outputs; First photo-coupler can use model 6N137 High-Speed Coupled Device, have signal isolation and enlarging function.Second optocoupler Clutch uses common low speed photo-coupler.
SPM uses PM200DSA060 type power models;SPM is so that switching speed is fast, loss It is small, low in energy consumption, have the advantages that multi-protective function, strong antijamming capability, need not take anti-static precautions, small volume electric power electricity Subdomains obtain more and more extensive application.PM200DSA060 type power models are exactly Typical Representative therein.Intelligent power mould It is made up of inside block PM200DSA060 high speed, low-power IGBT and gate leve driver.Wherein, IGBT is GTR (huge crystal Pipe) and MOSFET's is compound, and GTR is driven by MOSFET, thus the chip has GTR high current densities, low saturation voltage, height resistance to The advantages of pressure, MOSFET high input impedances, high switching frequency and low driving power.The chip internal integrates 2 IGBT, in chip There are driving and protection circuit, defencive function has control line under-voltage locking protection, overtemperature protection, overcurrent protection and short-circuit protection, When any of which defencive function acts, chip will export fault-signal.SPM PM200DSA060 internal circuits The peripheral circuit for its design specialized is needed without the signal isolation circuit of interference is prevented.
More than to the introduction of the chip it was found from:SPM PM200DSA060 devices contain drive circuit in itself, Only need to provide the pwm signal for meeting driving power requirement, drive circuit power supply and the electrical isolation for preventing interference when in use Peripheral circuit.
The utility model circuit concrete structure is as follows:Delivery outlet (output PWM ripples signal) and the first optical coupling of single-chip microcomputer The input of device (High-Speed Coupled Device) is connected, and the output end of the first photo-coupler and the control signal of SPM are defeated Enter end to be connected, that is to say that single-chip microcomputer is isolated to SPM by the first photo-coupler and send pwm control signal.Intelligence The fault-signal output end of power model is connected with the input of the second photo-coupler, the output end and list of the second photo-coupler The input port of piece machine is connected, and that is to say that the fault-signal output end of SPM is isolated to list by the second photo-coupler Piece machine sends failure alarm signal.
The driving signal output end of SPM is connected with the electric signal input end of ultrasonic transducer;Intelligent work( Requirement of the rate module to drive circuit output voltage is very strict:Drive voltage range is 13.5V~16.5V, and voltage is less than 13.5V Under-voltage protection will occur, voltage may damage internal part higher than 16.5V, and the utility model is powered using 15V.Single-chip microcomputer is also logical RS232 interface is crossed with snowfall sensor to be connected.Snowfall sensor is HSC-SE80 type snowfall sensors.SPM Power end VCC is connected with the output end of rectifier module.SPM can drive two ultrasonic transducers to realize more Big mechanical oscillation are exported to improve snow removing effect.
Utility model works principle is as follows:The utility model general principle is opened in single-chip microcomputer control SPM The turn-on and turn-off time of element (IGBT) is closed than controlling the size of alternating voltage and frequency, so as to producing driving ultrasonic waves The electric signal of energy device.The electrical power of input can be converted into mechanical output (i.e. ultrasonic wave) and pass again by ultrasonic transducer, The seldom a part of power of face its own consumption.In other words ultrasonic transducer is a kind of energy conversion device, and it utilizes material The piezo-electric effect of material converts electrical signals to mechanical oscillation.Can be with reality using caused mechanical oscillation in ultrasonic wave transmittance process Now to the removing of circuit accumulated snow, therefore this is a kind of non-contact snow removing mode of pure physics.Ultrasonic transducer can be divided into typically There are magnetostriction type and piezoelectric ceramic type etc., the utility model is using conventional piezoelectric ceramic type.Snow depth sensor is then used for The Snow Thickness of circuit and equipment accumulated snow is detected, just starts snow removing function when Snow Thickness reaches to a certain degree.
