Abstract
A model train unidirectional retardation controller can control DC track circuit power supply model train unidirectional driving retardation and is used to model sandbox railway termination protection. The controller consists of a power track, a power track gap and a retardation circuit. The retardation circuit comprising a LED and electric resistances is in parallel connection with both sides of the power track insulation track. When the coming conductive wheel crosses the gap, the LED will be stopped and the power supply circuit can realize train retardation by the electric resistances. In opposite direction driving, the polarity of the power track changes, the electric resistances are invalid and the train will return in normal speed. Therefore, the utility model can realize the automatic opposite direction retardation and normal opposite direction running of the train on designated position, with no sensor elements, except for the track.
Description
The utility model controller is the invention of the unidirectional deceleration of control direct current track power supply model train.
Be the Reduced Speed Now of implementation model train at present, way is to change the track supply voltage.But at the train that travels near the position of railhead, if it is untimely to slow down, train will plunge off the tracks, and have an accident.
The purpose of this utility model provides a kind of succinct controller that must any other device except that track for a train; realize that train is in the automatic Reduced Speed Now of assigned address forward; backward going then speed is unaffected, therefore can be used for the protection of model sand table railhead.
The utility model controller is made of power rail, power rail gap and deceleration circuit.Power rail is the metal rail of conduction own, and the one side links to each other with the output of train power supply, and two power rails are laid on the insulation roadbed according to the train wheel anomaly is capable, and the support train wheel moves and motor power supply in car.Orbit gap is that train has one 1 millimeter clearance for insulation on the negative pole power rail when the direction running that hope is slowed down, and the realization power rail directly conducts electricity to connect and interrupts.Deceleration circuit is composed in parallel by the general commutation diode and the conventional, electric-resistance of rectified current greater than the train operating current, and resistance is train dc traction motor D.C. resistance twice or infinity.The two ends of this parallel network join with power rail clearance for insulation both sides respectively, and the diode cathode side is near direction to the car, when the conduction wheel of sending a car is crossed the gap, diode ends, current supply circuit must pass through resistance, therefore realizes train deceleration (when resistance was infinitely great, train stopped).During backward going, the power rail reversing, diode current flow, resistance is ineffective, and train can normally be return at full speed.
The utility model advantage: 1. except that track, do not establish any sensing element, can realize that train slows down or parking automatically at the assigned address forward.2. do not influence train train backward going.
Further specify and see accompanying drawing 1.Leave clearance for insulation (4) between power rail (2) and the power rail (3), after (5) connect positive source and (6) and connect negative pole, train metallic conduction wheel (1) on the power rail to left movement.Wheel is by behind the gap (4), and the power supply of power rail (3) must be by resistance and diode network, and diode ends, and resistance string is in current supply circuit, vehicle deceleration or parking.Vehicle is when right travel, and (5) connect power cathode (6) and connect positive source, diode current flow, and resistance is invalid by bypass, normal vehicle operation.
Claims (4)
1. controller of controlling the unidirectional deceleration of model train of direct current track power supply, this controller is made of the power rail that electric power is provided to train, power rail gap and deceleration circuit, it is characterized in that: when the direction running that train wishes to slow down, on the power rail clearance for insulation is set, is parallel with deceleration circuit at the two ends, gap.
