Description

The invention relates to electrical engineering and can be used to control multi-motor electric drives., In which any combination of switched on electric motors is possible, to control outdoor lighting, etc. .

The purpose of the invention is to reduce the cost of the design, installation and operation of the device through the use of connection cables with a capacity of one pair of wires with an unlimited number of objects, as well as to increase the reliability of operation of the device by introducing control of the inclusion of the object.

The drawing shows a diagram of the proposed device.

The device for remote control of electrical consumers includes a control panel 1, consisting of a control unit 2, the output of which is connected to the input of the encoder 3, the output of the latter is connected to the input of the switching unit 4, the output of which is connected to the input of the decoder 5, the output of which is connected to the input of the node 6 indication, and a switching unit 7, consisting of a switching unit 8, the input-output of which is connected to the input-output of the switching unit 4 of the control panel 1, and the output is connected to the input of the decoder 9, the first output of which is connected to the input of the circuit 10- a solid state generator, the output of which is connected to the first input of the memory unit 11, and the second outputs of the decoder 9 are connected to the second inputs of the memory unit 11, the outputs of which are connected to the input of the switching units 12, the output of which is connected to the winding of the executive relays 14, the end of which is connected to a common DC source wire, and encoder 13, the inputs of which are through open block contacts of the magnetic starters 15

are connected to the common wire of the direct current source, and the output is to the input of the switching unit 8 of the switching unit 7, the windings of the magnetic starters 15 are connected to the alternating current source through the open contacts of the executive relays 14.

The specific implementation of the individual nodes and blocks may be as follows: controls - buttons KM 1-1; indication means - LEDs AL 307 BM; encryption chip K 155 KP1; decoder

- microcircuits K 155 IDZ; memory unit - K 155 TM2 microcircuit; switching unit

- relay RZS 6; bounce circuit - DC amplifier (transistor MP 40); switching unit - relay RES 6 or RES 55.

The device operates as follows.

When the button of the control unit 2 is pressed, the signal is input to the encoder 3 and then to the switching unit 4, where it switches the operation of the control panel 1 from reception to transmission. Then the signal goes to the switching unit 8 of the switching unit 7 and then to the decoder 9. From the decoder 9, the signal goes to the memory unit 11 and then to the power-on unit 12. From the output of block 12, the signal is supplied to the executive relay 14 of the object, which includes a magnetic starter 15, which supplies voltage to the object. Block contacts of the magnetic starter 15 provide a control signal to the input of the encoder 13. From the output of the encoder 13, the signal through the switching unit 8 is fed to the switching unit 4 of the control panel 1 and then to the input of the decoder 5, from the output of which the signal is fed to the input of the indicating unit 6. The end signal passes in a similar way, only from the output of the decoder 9 it enters the end circuit, where the corresponding signal is generated.

Thus, the invention provides selective inclusion of objects (power consumers), general hang-up and control of the inclusion of objects. This reduces the cost of the design, installation and operation of the device by reducing the capacity of the connection cables to one pair of wires. This positive effect is provided due to the fact that the device is equipped with encoders and decoders, and the placement of the switching unit directly on the exchange together with the switching axis.
