Background technology
Since the Railway Electric, rolling stock has part to hang warning sign at climbing staircase upper position, and most of vehicle does not all have any warning mark, moreover warning sign is reminds people initiatively, can only play passive effect, have only when people self vigilance, just can see warning sign and cause vigilant.Neglect vigilance if work at ordinary times, will lead to serious electric shock casualty accident.
Summary of the invention
The object of the present invention is to provide a kind of acousto-optic warning device of preventing mistake scrambling and high voltage electric shock hurting of rail vehicle, it can be having people or object to climb railway locomotive staircase upper strata before being about to touch high-voltage fence, send acousto-optic hint, warning is near the personnel and the object of high pressure contact net, prevent that it is subjected to high-voltage electric shock injury even burns, thereby solve the frequent electric shock problem of electric railway for a long time, ensured the inside and outside personnel's in road personal safety.
Technical solution of the present invention is to constitute like this, it is characterized in that: it comprises that machine box and the signal processor MCU, ultrasonic emitting head, the ultrasound wave that are installed on the machine box box body receive head, flash of light warning light, phonetic alarm, solar panel, mu balanced circuit, charging control circuit and accumulator, and described ultrasonic emitting head and ultrasound wave receive a human body or an object of being located at railway locomotive climbing staircase the superiors passage must be through locating; Described ultrasonic emitting head, ultrasound wave receive head, flash of light warning light and phonetic alarm respectively by ultrasonic emitting driving circuit, ultrasound wave accept filter amplifying circuit, meet barrier light prompting warning circuit and meet barrier voice prompt alarm circuit and be connected with signal processor MCU; Described solar panel, mu balanced circuit, charging control circuit and accumulator connect charging successively, and accumulator is connected power supply with signal processor MCU.
Principle of work of the present invention is described as follows: when human body or object process railway locomotive climbing staircase the superiors passage, a ultrasonic emitting ultrasonic waves transmitted is blocked by human body or object and is turned back, (this moment, ultrasonic emitting head and ultrasound wave received head towards same direction, and signal processor MCU promptly starts follow-up warning work for receiving reflected signal to be received the head reception by ultrasound wave; Also can make ultrasonic emitting head and ultrasound wave receive head during concrete enforcement and be located at the passage two opposite sides respectively, no human body or object receive head through out-of-date ultrasound wave and are in normal accepting state, be obstructed through out-of-date signalling channel as people or object, signal processor starts follow-up warning work because of signal is interrupted), handle through signal processor MCU identification, to meeting barrier light prompting warning circuit and meeting barrier voice prompt alarm circuit and send action command, make the flash of light warning light signal that flashes, the phonetic alarm sound that gives a warning.Solar panel is subjected to charging control circuit control to charge in batteries.Mu balanced circuit is used to ensure the high-quality power supply of each consuming parts.
Than prior art, beneficial effect of the present invention is as follows: (1) can be having people or object to climb railway locomotive staircase upper strata before being about to touch high-voltage fence, send acousto-optic hint, warning is near the personnel and the object of high pressure contact net, prevent that it is subjected to high-voltage electric shock injury even burns, thereby solved the frequent electric shock problem of electric railway for a long time, ensured the inside and outside personnel's in road personal safety, improve safe labour productivity, had very big economic and social benefit; (2) compactness rational in infrastructure, stable performance, durable.
In order under the situation of cloudy day or solar panel electricity shortage at night, to guarantee the operate as normal of this device, further improvement in the technical proposal of the present invention is: be connected with standby power supply on the described signal processor MCU, also be provided with in the signal processor MCU and be used to gather the voltage signal of solar panel and convert the A/D thief hatch of digital quantity input to and the handover module of closing or start standby power supply according to the signal height that this thief hatch collects.The voltage that collects solar panel when signal processor just often can adopt the circuit that is connected to form successively by solar panel, mu balanced circuit, charging control circuit and accumulator to the signal processor continued power; When the voltage that collects solar panel when signal processor is lower than setting voltage, can switch to the standby power supply power supply by handover module.
For timely charge capacity according to accumulator opens and closes charging control circuit work, be connected with the charging control signal output line between described signal processor MCU and the charging control circuit, also be provided with another A/D thief hatch that is used to gather the voltage signal of accumulator and converts digital quantity input on the described signal processor MCU, the signal height that signal processor MCU collects according to this thief hatch and send to charging control circuit by the charging control signal output line and to stop or starting charging signals.The electric weight that collects accumulator as signal processor MCU just often, charging control circuit is not worked; When accumulator electric-quantity is lower than setting value, promptly start charging control circuit work.
For the working condition of shows signal processor, also be provided with the LED indicating circuit on the described signal processor MCU.
