detailed description of the invention:below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in accompanying drawing 1, accompanying drawing 2, alarm is designed to portable set in appearance.Have employed spring carrier arm, magnetic-adsorption two kinds of modes when being installed on mine car, facilitate dismounting like this.Can see that from accompanying drawing 2 No. 9 for high strength bar magnet.When No. 1 clip is after mine car frame, magnet has been adsorbed on mine car iron sheet firmly.Distribute on the left of alarm front panel 3 buttons, and being respectively " ON " button, " OFF " button, " volume " button, is display screen component on the right side of button.When equipment is used for the use of the ground such as mine car, people's car, pressing alarm " ON " button, the first blinking light of alarm, waits for vehicle operating.After vehicle operating, alarm detects the vibrations jounce condition of vehicle, automatic triggering voice circuit, and the sound-content recorded in advance is exported by loudspeaker after power amplifier amplifies.Now can press " volume " button according to on-site noise environment, varying cyclically volume.Vehicle after operation voice message sound and blinking light works with the operation of vehicle always, and after vehicle parking after vibration sensor can't detect the vibration signal of vehicle, alarm only cuts out voice output automatically, and light warning continues flash caution.If now do not need alarm work can press alarm " OFF " button, close light flash, close alarm.
Accompanying drawing 5 is alarm electrical principle wiring diagram, alarm by sealing supply module, master control voice module, vibration module, display screen, loudspeaker, input key, cradle seven part form.Sealing supply module inside have employed high-capacity nickel-hydrogen battery group series-fed, and this power supply exports essential safety source after the process of essential safety protection circuit, in alarm, master control voice module, vibration detection module, display screen are powered.Intrinsic safety electric source is connected to the XJ1 terminal of master control voice control plate, and 3 by being bonded in its XJ2 terminal, loudspeaker is connected to its XJ3 terminal, and display screen is connected to its XJ4 terminal.
Master control voice plate brief introduction of work principle: master control voice module inside is made up of voltage stabilizing IC, logic circuit, sound circuit, blinking light drive circuit, audio power amplifying circuit.After intrinsic safety electric source input, a road powers directly to power amplification circuit, light output circuit, gives logic circuit, sound circuit, blinking light drive circuitry after an other route voltage stabilizing IC voltage stabilizing.8.5V intrinsic safety electric source is divided into 4 tunnels after being accessed by XJ1 as shown in Figure 6, and the 1st tunnel exports after rectifier U1 regulator block LM2940-5V voltage stabilizing that 5V voltage is voice module, shock module is powered; 2nd tunnel access rectifier U3 bistable trigger-action circuit NE555, for key-press input provides supply voltage; 3rd tunnel access rectifier U8 audio-frequency power amplifier TEA2025B powers; Optocoupler U7 conducting during pressing " ON " button, optocoupler drags down 2 pin of U3 after exporting, its 3 pin exports high level, and this high level keeps after button lifts always.The N ditch FET output low level be connected with 3 pin drives U1 voltage stabilizing to export 5V voltage.5V voltage exports two-way, and a road powers to voice module, shock module, allows them be in holding state, and another road powers to display drive circuit, and drive circuit is electric in running order because obtaining.It is different that rectifier U4, rectifier U5 form their concussion frequency of multivibrator respectively, and U4 is set in 20HZ, and U5 is set in 5HZ.U4 controls the positive pole that triode Q3 drives display screen, makes its high-speed switch.U5 controls the negative pole that triode Q4, Q5 drive red, blue high-brightness luminous pipe in display screen, makes their alternately flickers at a slow speed.Such speed array output mode makes the display effect of light warning more eye-catching.
Vibrating sensor is plugged in S2 contact pin, and after the vibrating sensor being in holding state detects the motor message of vehicle, output low level controls voice module, after voice module receives trigger command, transfers duty to by standby.The audio signals such as the voice that output records or music.Audio-frequency power amplifier U8 amplifies the power exporting 5W after receiving audio signal, drives loudspeaker to export audible alarm.After shock sensor after vehicle parking can't detect the vibration signal of vehicle, alarm cuts out voice output automatically, and light warning continues flash caution.
Often press " volume " button, volume can reduce one grade, when reduce to minimum after press volume again and can add one grade, so pressing volume can be added to maximum, so circulates.Always have 8 volume shelves to select for user, each shelves can reduce 4dB, user-friendly.If now do not need alarm work can press alarm " OFF " button, close light flash, close alarm.
