The specific embodiment
as Fig. 1, Fig. 2 and a kind of mine explosion-suppression safety-type phonetic sound light crossing-signal shown in Figure 3, comprise power-supply system, control module and display module, power-supply system is connected with display module with control module respectively, control module is connected with display module, also comprise for the language acousto-optic alarm module of reporting to the police, speed sensor for detection of electric locomotive speed in mine is connected with control module, control module is connected with language acousto-optic alarm module, described power-supply system comprises voltage transformer and intrinsic safety electric source, the alternating current that electrical network comes is through transformer pressure-reducing, rectification, become direct supply after filtering, output direct current 12V voltage after twice voltage stabilizing of twice current limliting, again by being connected respectively to after intrinsic safety electric source on control module and display module.Be provided with long-range RS485 communication interface and conversation module on described control module, the conversation module is connected with on-the-spot transmitter.Display module is comprised of red light, green light, charactron, and red light, green light and charactron are connected with control module and are connected, and red light and green light consist of by LED array.
Working process of the present utility model is as follows:
A, control module: when needs start winch, the driver connects the signal switch of garage control module, circuit by static conversion to normal working, signal of control module output removes to control playback circuit and begins playback, and another road is extinguished green light, and red light begins flicker, the prompting people take care, drive a vehicle complete after, the driver disconnects master cock, circuit is in the quiescent operation state.
When the people below ramp need to drive, press signal button, loudspeaker send approximately 1000Hz signal sound, traffic lights on the speech signal machine of driver front are simultaneously luminous, as prescribed is to starting signal of driver, and the driver just can drive, and has realized semiotic function.
A select switch (the right toggle switch on control desk) is arranged in control module, when communicator is arranged on the driver front, allow be in closure state No. 1 of switch, at this moment, the speech signal machine of driver front is not sent out speech signal sound and flash signal, during driving, light is bright, in order to avoid disturb driver's normal operation, and in the local time of being installed to other, allow toggle switch be in open position, this function is inoperative.
B, language acousto-optic alarm module: have language alarm function.
Language acousto-optic alarm module processes integrated circuit by a specific language and peripheral cell consists of, at first phonetical circuit takes out the digital signal of memory inside in control module (digital signal in memory device is recorded by producer), after treatment, revert to the analogous language signal, the process low-pass filter is except after making an uproar again, the ingoing power amplifier, the signal after amplification promotes the loud speaker sounding.
The controlled module controls of language acousto-optic alarm module,
Send alarm language signals such as " drive a vehicle, inaccurate pedestrian ", the prompting people take care, and as just when the playback, need signal or communication, and after pressing the signal and communication button, playback stops.During the danger signal communication, playback starts anew to play.
C, semiotic function:
Signal circuit consists of self oscillator by an amplifier and peripheral cell, after pressing signal button, one the tunnel is added to control, flashing circuit shows light, another road is started working oscillator, the oscillator signal of output is added to the power amplifier input end, except driving the machine loud speaker sounding, go back the output AC carrier signal in the lower box on No. 23 terminals so that and outer realize contact.
D, call function:
Consist of amplifier by an amplifier and peripheral cell, after key the mike, transmitter access amplifier input end, signal one tunnel after amplification is added to the power amplifier input end, amplify rear drive the machine loud speaker sounding, another road is added on leave from office annunciator terminal, in order to converse with outer realization, talking mode is duplex intercommunicating.
E, get function ready:
Use signal in the colliery, generally all will get ready, is exactly that annunciator sends several several sound and represents what meaning (as promoting, transfer, carry the people, extract etc., sound implication is fixed by the ore deposit square gauge).
F, RS485 communication function:
The RS485 communication interface is arranged in the control desk circuit, can facilitate real multiple spot, Long-distance Control.
The G display circuit
Display circuit is by red, green light, and charactron forms, and continuous light on and off when using due to light uses bulb life short, so the machine replaces red, green light with the luminotron dot matrix, circuit is identical, and just the luminotron color is different.The bright expression normal condition of green light, when red represents alarm condition, and state is got in the bright expression of red blue flash ready and number of times is got in the charactron demonstration ready, avoids misoperation, and traffic lights entirely go out and are illustrated in the on-line talking state.
The utility model has also possessed blocking function between partial zones except possessing above basic function, set forth blocking function between partial zones of the present invention as an example of the electric locomotive overspeed protection example.
(1) on electric locomotive, speed sensor detects speed signal by being arranged on when annunciator, and the internal arithmetic of the control desk by annunciator relatively demonstrates values for actual speed and the accumulative mileage of electric locomotive, and is bright at normal driving alarm device green light, and do not report to the police.
(2) when display speed during greater than the overspeed warning value set, annunciator sends warning signal, and when red, reminds the driver to slow down, and after the driver was slowed down, speed automatically terminated warning lower than warning value alarm, and the red light green light that goes out in display part is bright.
(3) when display speed surpassed the overspeed protection value, annunciator sent alarm sound, when red, and the output contact of disconnection electric locomotive, and speed is fallen rear annunciator and is automatically recovered original state.
