Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making under creative work prerequisite, and the every other embodiment obtained, all belongs to scope.
Core of the present invention is to provide a kind of electric locomotive and moves back and take advantage of illuminalive power-supply circuit.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment one
A kind of electric locomotive moves back takes advantage of illuminalive power-supply circuit, this circuit comprises lighting device, main switch is connected with between this lighting device and storage battery, also comprise by described battery-driven floor light circuit, wherein said floor light circuit comprises the self-resetting switch controlling described floor light connecting and disconnecting of the circuit, and the time-delay relay to be controlled by described self-resetting switch, when described time-delay relay obtains electric, described lighting device and described storage battery are connected; After arriving delay time, described lighting device and described storage battery disconnect by described time-delay relay.
In concrete enforcement, after electric locomotive arrives at a station, disconnect main switch, now lighting device and storage battery is separated, and therefore, lighting device is in OFF state.Press self-resetting switch, because self-resetting switch controls time-delay relay, when self-resetting switch is pressed, time-delay relay just obtains electric energy from storage battery, when time-delay relay obtains electric, just connected the loop at lighting device and storage battery place, now, storage battery is power illuminating device again.Because time-delay relay has the function of time delay disconnection, when arriving the delay time of time-delay relay, time-delay relay just disconnects lighting device and storage battery, and now, lighting device cannot obtain electric energy from storage battery, is therefore again in OFF state.If when next class of driver and conductor waits for bus, directly closed main switch.
What the present embodiment provided moves back the normal power supply taking advantage of illuminalive power-supply circuit neither to affect electric locomotive, can also take advantage of moving back, and when disconnecting main switch, provides illumination, ensure personal safety by the delay function of time-delay relay for driver and conductor.In addition, the present invention is without the need to increasing extra power supply, and cost is low.
It should be noted that, the present embodiment does not specify the concrete form of floor light circuit, as long as can realize turning off at main switch, when self-resetting switch is pressed, in the delay time of time-delay relay, lighting device can throw light on, after reaching delay time, lighting device extinguishes.
As a kind of optimal way, described delay time is 1 minute.
In concrete enforcement, the delay time of time-delay relay can set according to actual conditions, due to move back take advantage of lighting circuit be exactly conveniently driver and conductor leave electric locomotive safely, therefore delay time is 1 minute.But not representing must be 1 minute, it within 1 minute, is only a kind of preferred mode.
As a kind of optimal way, the voltage of described storage battery is 110V.
Embodiment two
In order to be that those skilled in the art more understand electric locomotive provided by the invention and move back and take advantage of illuminalive power-supply circuit, illustrate the connected mode of circuit below.
Fig. 1 is that a kind of electric locomotive provided by the invention moves back and takes advantage of illuminalive power-supply circuit.Described floor light circuit 1 is:
