Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model will be further described.
Crashproof sound prompt device, it is characterized in that, form primarily of data trap, repeater and phonetic alarm, be installed in contact system vertical rod, described data trap gathered car data, and by car data with wireless transmission to repeater, interrupter by cross car data forward deliver to phonetic alarm, phonetic alarm remind pedestrian have train to pass through;
Described data trap is formed primarily of pillow end data pick-up transducers, the first lightning protection unit, charge amplifier, filter, MCU, wireless antenna, DC/DC conv, solar power processing unit, the second lightning protection unit, storage battery and solar panels, described pillow end data pick-up transducers gathers the vibration signal of Train Approaching, described vibration signal amplifies with charge amplifier after the first lightning protection unit, vibration signal through amplifying reaches filter, filter reaches MCU after removing interference again, and vibration signal is launched by described MCU connection control wireless antenna; The electric current that described solar panels export is connected to solar power processing unit and prevents battery current super-charge super-discharge after the second lightning protection unit, and solar power processing unit connects described DC/DC conv; The mouth of described DC/DC conv to be connected with wireless antenna, charge amplifier, filter and MCU through multiple programmed switch powers, and the control end of DC/DC conv is by MCU connection control.
Embodiment one
As shown in Figure 1, sensor signal, after lightning protection unit, carries out data acquisition with the AD mouth that charge amplifier carries out amplifying, MCU is sent in filtering.Solar panels export sends into solar power administrative unit through lightning protection unit.Solar power administrative unit possesses and prevents over-charging of battery from crossing playing function, to protect battery, and extending battery life.Battery exports and powers to MCU after low noise DCDC, is powered respectively by multiple programmed switch to wireless, amplification, filter unit simultaneously.Therefore, MCU can control the supply of each element circuit power supply, reaches the requirement that each element circuit " only needs just to power ", reduces system power dissipation.
Close all external powers after data trap powers on, then enter STOP(and stop) pattern, interval 10ms wakes up automatically, opens amplifier and filter power supply, pick-up transducers incoming signal, through digital filter, has identified whether train and has passed through.If there is train to pass through, open radio-cell power supply, send train arriving signal always, confirm until receive warning end equipment, then enter STOP state.Go back detection alarm test button when equipment wakes up, if be pressed, by transmission warning test signal, during convenient installation, whether verification msg collector communicates normal with phonetic alarm.In wake-up states and STOP state, house dog all will be worked.Crash or program fleet once unexpected, will system restart be caused.
Embodiment two
As shown in Figure 2, phonetic alarm power supply, wireless portion are identical with data trap.Voice module exports and drives loudspeaker by power gain.Because analog amplifier efficiency is low, power consumption large, therefore select digital power amplifier.In order to make voice loud and clear, it is 100W that power amplifier power is not less than 60W(actual), power supply voltage must be greater than 12V.The miniwatt solar panels of solar panels manufacturer-supplied are based on 12V, 36V.Because 36V physical dimension is large, be unfavorable for that Railway Site is applied, and adopt DCDC to boost, switching noise causes voice tone color bad, therefore adopts two 12V solar panels series-feds.
Close voice and power amplifier power supply after phonetic alarm powers on, read real-time clock.If current time allows time range in warning, open radio-cell power supply, intercept the data whether having data trap.If exceed time of fire alarming scope, enter STOP state.Once receive data trap to cross car data, open voice and power amplifier power supply, start audio alert, alarm voice continues to stop after 1 minute.Phonetic alarm end pieces comprises two cover solar panels, loud horn, a phonetic alarm cabinet and wireless antenna four part.The cable of solar panels, loud horn and wireless antenna is all connected to phonetic alarm cabinet by KSS-PA10 pipe.Its solar panels are identical with the mounting design of cabinet.
