Abstract

The invention relates to a measurement technique and can be used to determine the direction of linear and rotational movement of an object. The aim of the invention is to simplify the design of the device. When the object 13 is moved past sensor 1, the latter is triggered and through normally closed contacts 4, relay 5 closes the power supply circuit of the relay 2 winding. Contacts 3 relay 2 self-blocking. Upon further movement of the object, the circuit is brought back to its initial state when the trip sensor 7 is triggered, which closes the power supply circuit of relay 8, opens contact 9, and relays 2 and 5 de-energize. 1 il.

The invention relates to a measurement technique and can be used to determine the direction of linear and rotational movement of an object.

The purpose of the invention is to simplify the design of the device.

The drawing shows a diagram of the device for determining the movement of an object.

The first measuring circuit consists of a track sensor 1, a winding relay 2 and a shunt track sensor of normally open contacts 3 relays 2 and normally closed contacts 4 of relay 5. A second measuring circuit consists of a track sensor 6, a winding of relay 5 and shunt track sensor 6 of normal pa3ONfKHyTbix contacts 4 relays 5 and normally closed contacts of relay 2. The reset circuit consists of a track sensor 7 and a relay winding 8. Normally closed contacts 9 of relay 8 are connected between the power source and the windings of relays 2 and 5, Normally open contacts 10 and 11 relays 2 and 5, respectively, are connected to the addition and subtraction bus of the reversible counter 12 to a power source.

The device works as follows.

Object 13 makes a cyclical movement, for example, on a circular trajectory: torii. When it is moved past sensor 1, the latter is triggered and through normally closed contacts 4, relay 5 closes the power circuit of relay 2 winding. Through contacts 3, relay 2 self-locks and simultaneously breaks sensor 6, and contacts 10 connects the reverse counter addition bus 12. object 13, the travel sensor 6 triggers, but since the contacts 3 of the relay 2 in this circuit are open, the relay 5 does not trigger and the reversible counter does not switch. When the object 13 passes by the track sensor 7, the latter closes the power supply circuit of the relay 8, the contact 9 is opened, and the relays 2 and 5 are de-energized. When the object moves in the opposite direction, it first triggers the travel sensor 6.
