Abstract
The utility model discloses an impulse relay control circuit and rail transit car, including two interconnect from the reset switch, two from the winding connection of reset switch with impulse relay, impulse relay's solenoid ground connection, impulse relay's contact and one of them connect the first control power after the reset switch is parallelly connected, the another one connects the second control source from the reset switch, controlled on -vehicle consumer is inserted to impulse relay's contact. The utility model discloses use an impulse -type relay, replace four relays in the whole car of prior art to four buttons of a ON / OFF in reset button replaces the primary wire structure are only adopted, whole functions of available circuit can be realized, simple structure, with low costs, the fault rate is low.
Description
Technical field
This utility model is related to vehicle low-voltage control circuit field, particularly a kind of time pulse relay control circuit and track
Vehicular traffic.
Background technology
In prior art, if control same group of equipment in diverse location powered, the circuit built typically can be reduced to
Simplified electrical circuit diagram as shown in Figure 1, car load adopts four Self-resetting buttons, four relays to complete jointly, and cost and fault rate are all
It is higher.
General railcar or light rail vehicle two ends drivers' cab are distant, if the control of circuit can only be complete at one end
Into, then driver is might mean that when returning the vehicle to the garage and knock off, the other end must be gone to and go to close the circuit, waste time and energy, thus it is different on vehicle
Subsystem be substantially all using it is above-mentioned can both-end operation self-sustaining control circuit, button generally adopt Self-resetting button, one
Recover immediately after the operation of end, do not affect other end of operation.
The operation principle of Fig. 1 self-hold circuits：Two terminal circuits adopt symmetrical structure, be respectively provided with the control of on an off by
Key, button is Self-resetting button；It is respectively provided with control and opens and control the corresponding relay KM1 and KM2 for closing.When one end, driver presses
Under open after button, KM1 relays action immediately, its normally opened contact adhesive defines self-hold circuit, other end of KM1
Action simultaneously forms self-hold circuit, and full-vehicle control power supply to " controlled vehicle-mounted electrical equipment " powers；The now driver at two ends
Operable pass button, control KM2 relay moments obtain electric, KM2 relays obtain it is electric after its normally-closed contact disconnect, so as to disconnect two
The self-hold circuit at end, even if with " controlled vehicle-mounted electrical equipment " dead electricity, reaching the purpose of its shut-off of control.
The content of the invention
Technical problem to be solved in the utility model is, not enough for prior art, there is provided a kind of time pulse relay control
Circuit processed and rail traffic vehicles.
To solve above-mentioned technical problem, the technical scheme that this utility model is adopted is：A kind of time pulse relay control electricity
Road, including two self-resetting switchs being connected with each other；Described two self-resetting switchs are connected with the line bag of time pulse relay；It is described
The line bag ground connection of time pulse relay；The contact of the time pulse relay is in parallel with one of self-resetting switch to be followed by the first control
Power supply；Another self-resetting switch connects the second control power supply；Access controlled vehicle-mounted electricity consumption in the contact of the time pulse relay
Equipment.
Described two self-resetting switchs are separately positioned in two driver rooms of rail traffic vehicles.
This utility model additionally provides a kind of rail traffic vehicles, using above-mentioned time pulse relay control circuit.
Compared with prior art, this utility model have the advantage that for：This utility model uses a pulsed
Relay, substitutes four relays of car load of prior art, and substitutes primary circuit knot only with an ON/OFF Self-resetting button
Four buttons in structure, are capable of achieving the repertoire of available circuit, and simple structure, low cost, fault rate is low.
Description of the drawings
Fig. 1 is that current both-end operates self-sustaining control circuit schematic diagram；
Fig. 2 is the embodiment circuit theory diagrams of this utility model one.
Specific embodiment
As shown in Fig. 2 time pulse relay belongs to passive element, i.e., power supply need not be additionally supplied when itself works, be different from
Common relay provides stable power supply must to when its closing of contact is needed its coil.A pulse letter is provided when outside
Number to after time pulse relay, time pulse relay will control its one state of contact upset, that is, the contact for disconnecting closes immediately or closes
The contact of conjunction disconnects immediately, provides after a pulse again, will again carry out state upset.
As shown in Fig. 2 arranging the button ON/OFF of Self-resetting where two ends need driver operation, the switch both can be with
Control electrical equipment is powered, it is also possible to control electrical equipment power-off.When any one end of two ends drivers' cab operate the Self-resetting by
After button, time pulse relay KM1 can receive a pulse signal, and now KM1 will control its contact rollover states, between different conditions
Upset, makes vehicle both to have realized that car load obtained the dead electricity of electric electrical equipment and can also realize the upper electricity of car load dead electricity electrical equipment,
And this control mode equally realizes two ends drivers' cab and identical control is independent of each other.
At two ends, drivers' cab arranges guest room light switch, and light switch adopts the button pattern of Self-resetting, guest room illumination to open
Pass can both open the illumination of car load guest room, it is also possible to turn off the illumination of car load guest room.When drivers' cab any one end in two ends operates visitor
After the light switch of room, time pulse relay KM1 can receive a pulse signal, and now time pulse relay will control its contact flip-like
State, for example：The vehicle that the illumination of car load guest room is closed will open guest room illumination, and the vehicle that car load illumination is opened will close guest room and shine
It is bright.
In addition during opening or closing, the driver at two ends can be controlled simultaneously, and be independent of each other.
