Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of mining electric locomotive illuminating lamp automatically switches and the automatic ring device of loudspeaker, comprise flameproof cabinet and acousto-optic circuit, upper cover 2 is housed on described flameproof cabinet, casing one end is provided with wire connection cavity 3, flame proof terminals 6 are housed in wire connection cavity 3, and wire connection cavity 3 seals by installing plate 4, and wire connection cavity 3 one sides are provided with inlet wire port 5;
Described acousto-optic circuit comprises intrinsic safety Switching Power Supply, rotary switch 1, rotating sensor, door latch switch, PLC, relay and load, and described rotary switch 1 is arranged on upper cover 2; Described intrinsic safety Switching Power Supply, PLC, relay are installed in Flameproof box; The input end of described intrinsic safety Switching Power Supply is received the primary power end of electric locomotive, and output terminal is electrically connected with PLC by rotary switch, rotating sensor, door latch switch respectively; Described rotating sensor is fixed on locomotive axle place, and by detecting the rotation direction of locomotive axle, the different voltage signal of output phase is delivered to PLC input end and detected; Door latch switch be contained on locomotive door, in the time that door is closed to PLC input signal; PLC output terminal is connected with load by relay respectively, and described load is illuminating lamp and loudspeaker, and illuminating lamp and loudspeaker are installed on locomotive, and described illuminating lamp comprises front lamp, front red light, rear lighting lamp, rear red light.
As further improvement of the utility model, described upper cover 2 is by bolted on flameproof cabinet, and installing plate 4 is by bolted on wire connection cavity 3, and repair demolition is easy for installation.
As further improvement of the utility model, the faying face of described flameproof cabinet and upper cover 2, wire connection cavity 3 are flanged flameproof joint with the faying face of installing plate 4, install overall flame proof effective, effectively ensure construction safety.
By the inlet wire port 5 on the wire connection cavity 3 of flameproof cabinet and flame proof terminals 6, this device is assembled complete.This mining electric locomotive illuminating lamp automatically switches and the power supply of the automatic ring device of loudspeaker is provided by electrical locomotive power, and power supply voltage range is DC70-250V, and output+24V voltage after the step-down of essential safe type Switching Power Supply, offers acousto-optic circuit.Door latch switch device is on door, and rotating sensor is fixed near locomotive axle place, is furnished with status indicator lamp, because sensor bulk is little, can be installed on the occasion of narrow space.This sensor has four lead-in wires, can provide the dephased signal of two-way tool, therefore can differentiate locomotive axle rotating.This two paths of signals is sent to the input end of PLC, after logic judgement, by auxiliary reclay, load is done to corresponding control.In the time that locomotive starts, PLC judges locomotive running state according to sensor input signal.In the time that locomotive advances, front lamp and rear when red, rear lighting lamp and front red light go out; In the time that locomotive retreats, rear lighting lamp and front when red, front lamp and rear red light go out, thus before and after realizing locomotive, illumination is automatically switched, without manual operation.When locomotive is after two minutes out of service, front and back illuminating lamp is closed, and one second stroboscopic of front and back red light, plays parking warning effect.Equally, in the time that PLC senses sensor input signal, illustrate that locomotive starts to start, PLC passes through the automatic ring of Control electronic horn three times, and prompting front pedestrian takes care.When PLC senses locomotive operation signal, but now door is not shut, and door latch switch does not have closure, and PLC does not receive a block signal, and now PLC output signal, yowls by Control electronic horn, stops until car door is shut.In the time not needing acousto-optic automatically to control, by rotary switch 1 on controller car door, cut off PLC input signal, now program stopped work.
After the automatic switchover of this illuminating lamp and the automatic ring device of loudspeaker are contained on locomotive, before and after making, illumination conversion is with loudspeaker ring without manual operation, and guarantee trainman notice is concentrated, and can operate physically and mentally locomotive operation, greatly improve locomotive transportation safety, stopped the generation of security incident; The door latch switch of simultaneously installing on locomotive door also moment prompting driver operates according to code, eliminates safe hidden trouble; This apparatus structure is simple, and wiring is easy, and volume is little, and cost is low, is convenient to electric locomotive and installs additional and reequip.
