Embodiment
The present invention is described in further details below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, a kind of locomotive of the invention is driven over the speed limit prompting warning system, including working power, velocity pick-up Device 1, A/D change-over circuits 2, the first single-chip microcomputer 3, second singlechip 4, speed display device 5 and overspeed alarm device 6, speed are passed Sensor 1 is arranged on locomotive, and the speed collected output sine voltage is output to A/D change-over circuits 2 by velocity sensor 1, The output digital quantity of A/D change-over circuits 2 is transmitted to the first single-chip microcomputer 3, the first single-chip microcomputer 3 setting hypervelocity numerical value and by the digital quantity of reception The speed parameter calculated sends second singlechip 4 to, and second singlechip 4 controls speed to show according to the order of the first single-chip microcomputer 3 Showing device 6 shows locomotive speed, when locomotive speed exceedes the hypervelocity numerical value of setting, the control overspeed alarming dress of second singlechip 4 Put 5 alarms.
In the present embodiment, velocity sensor 1 selects T03S magnetoelectric tachometric transducers.T03S magnetoelectric tachometric transducers , can be to the output of locomotive electric cad system control device and quilt for the noncontacting proximity sensor of Railway Diesel Locomotive Engine rotating speed can be measured The sinusoidal frequency signal that its rotating speed of measurement equipment is directly proportional.T03S magnetoelectric tachometric transducers shell is the stainless steel tube of M16 × 1, preceding Hold as the pure iron of φ 3.5, inside install coil etc. and by epoxy encapsulation.T03S magnetoelectric tachometric transducers lead-out wire is used X12K4P aviation plugs seat, its socket part is encapsulated after justifying through car with stainless steel screwed tube, and four terminals are docked, therefore Plug lead-out wire can be connected to the end of arbitrary neighborhood two.
In the present embodiment, the effect of A/D change-over circuits 2 is that the analog quantity of sensor is converted into digital quantity to supply single-chip microcomputer Read.The size of T03S magnetoelectric tachometric transducer output voltage values is the sinusoidal frequency signal being directly proportional to rotating speed, and monolithic Machine can only be handled digital quantity.Accordingly, it would be desirable to complete analog-digital conversion process by A/D converter.To ensure that speed is joined The accuracy of number measurement, selects the A/D change-over circuits of High Resolution to complete analog/digital conversion, it is further contemplated that performance and valency Lattice ratio uses ICL7135 integrated circuits.ICL7135 is complete 4 half double integral A/D converters of MOS techniques, can be joined in unipolarity Examine and carry out A/D conversions under voltage supply to the analog voltage that bipolarity is inputted, and export auto polarity and differentiate signal.It is employed The technology of self-correcting zero, it is ensured that the long-time stability of zero point at normal temperatures, the μ V/ DEG C of temperature coefficient < 2 of zero point, simulation input can be with It is differential wave, input impedance is high, input zero point leakage current < 10pA.
In the present embodiment, the first single-chip microcomputer 3 and second singlechip 4 are repeatable erasable using MCS-51 series AT89C55WD double mcu control modes.Using AT89C55WD double mcu working methods, primarily to being connect needed for solving Mouth control problem, improves data-handling capacity and speed.AT89C55WD single-chip microcomputers belong to AT89C52 Strong MCUs, include 20KB Flash program memory, it is completely compatible with 80C52 instruction systems and output pin.Key property:The Flash erasable longevity Life 1000 times, RAM256 bytes, with programmable I/O mouthfuls of 32 line(P0, P1, P2 and P3);Include 3 programmable timers (T0, T1 and T2), 1 programmable serial communication port UART;With 8 interrupt sources, 68 interrupt vectors and interrupt priority;It is low Power consumption battery saving mode is idle pulley and power-down mode;3 grades of program locking bits, hardware watchdog timer, Double Data pointer DPTR0 and DPTR1, with power-down flag POF, working power is 4.0 ~ 5.5V, and maximum operating frequency is 33MHz.
In the present embodiment, overspeed alarm device 5 includes buzzer, because the operating current of buzzer is general than larger, So that the I/O mouths of second singlechip 4 can not directly drive, so provided with amplification between buzzer and second singlechip 5 Circuit, amplifying electric current using triode C8550 just can be with the characteristics of triode C8550 has low-voltage, high current.Honeybee Positive pole connects positive source when the polarity of ring device is installed, and buzzer negative pole connects triode C8550 emitter stage.Second singlechip 4 I/O mouthfuls of driving buzzers.Drive the setting of buzzer mode fairly simple using I/O mouthfuls of timing trigging signals, it is only necessary to right Waveform analysis is once.Because the signal of driving is just the μ s of cycle 500, dutycycle is 1/2duty square wave, it is only necessary to every 250 μ s carry out a level upset, it is possible to obtain driving the square-wave signal of buzzer.
In the present embodiment, speed display device 6 is 320 × 240 colour liquid crystal display devices, and working power is using four sections 1860 lithium batteries concatenation 12V powers, big with the lightweight capacity of lithium battery group.
The present invention is described in detail above, the explanation of embodiment be only intended to help to understand the present invention method and Its core concept, its object is to allow the personage for being familiar with this art to understand present disclosure and implement according to this, and It can not be limited the scope of the invention with this.Any equivalent change or modification in accordance with the spirit of the invention, should all contain Cover within protection scope of the present invention.
