SU26226A1 - Device for controlling traffic control signals - Google Patents

Description

For traffic control purposes, so-called "traffic lights," signal lights are used to provide colored signals. Apparatus consisting of a continuously rotating clock mechanism and a switchgear associated with it can be used to automatically turn on signal lamps.

At the same time, devices for controlling signals using alternating current pulses, for example, from an electric watch circuit, are already known.

The drawing shows the electrical circuit of the proposed device.

The device consists of two relays: 1 - polarized and 2 - not polarized. Relay 1 is equipped with a rotary bark 3, controlled by pulses coming from a circuit and moving from one extreme position to another, thereby switching permissive .TZj and suppressive JIz signals. The relay 2 winding is connected to the circuit through terminals b, t in parallel with the relay 1 winding. When current impulses are received, the measles 4 relays 2 are turned on and the warning signal Lz is turned on, and the signal circuit Jli or L is turned off depending on the position of the core 3.

D. R. “-

In order to carry out the signal switching order, one of the contacts of the relay 2 is electrically connected to the core 3 of the polarized relay 1.

Thus, the required three switchings are achieved at the expense of only. two changes in current direction. In the event that the burning time of the J / s signal is required to be made longer than the pulse duration, an adaptation with a thermal contact for retardation can be used in the circuit of relay 2. laziness his action.

The subject matter of the invention.

Claims (2)

1. A device for controlling traffic control signals using alternating current pulses, for example, from an electric clock circuit, characterized in that, in parallel with: polarized relay 1 connected to the circuit, relay 2 is switched on, and its switch 4 is used to alternately turn on to the signal circuit of a sb warning Lz, permissive Jl-i or prohibitive Lh signals, for which one of the contacts of the relay 2 is electrically connected to the corona 3 of the polarized relay 1. 2. In the device according to claim 1, use a device for slowing down the operation of relay 2 for a time longer than the duration of the control of the device of electrical pulses.
