Description

This invention relates to the field of automation and telemechanics.

Devices for remote control of objects are known, comprising a disconnecting relay connected to the power supply minus; control buttons assembled in a matrix and connected via a switch and normally closed relay contacts to the source and executed on the control matrix relay, alarms and controls in which vertical cables with auxiliary relays and horizontal buses with executive relays are connected to the first and second normally open contacts control buttons respectively. In such devices, it is necessary to use a larger number of control lines with a significant number of controlled objects.

In order to reduce the number of control lines in the proposed control matrix device, signaling and control, tires contain the coordinate relays connected to the third normally open contacts of the control buttons. Moreover, the coordinate relays of the control matrix with another output are connected to the positive power source via series-connected diodes and normally open relay contacts with information. Executive relays are connected to horizontal

LHHHaM Through 1C) therefore United normally open contacts of auxiliary n coordinate relays. The other output of the trip relay is connected to the positive power source through series-connected diodes and normally open contacts of the information relay.

Pa figs. 1 shows a functional diagram of the proposed device for remote control of a set of objects; in fig. 2 - a high-performance electrical circuit for one-place control of one object from a given sovokunnost of objects.

The device contains buttons / controls assembled in matrix 2; switch 5 is a floor-mounted power supply; alarm matrix 4 on buses 5 (X), 6 (Y) and 7 (Z), auxiliary 8 relays with contacts 9,

coordinate pCvie / С and // with contacts 12 and 13, respectively, and elements 14 connected to tires X with contacts 9, 12 and 13; and matrix / 5 equalized at 16 (X), 17 {U) and 18 (Z), auxiliary relays / 9 with contacts

20, coordinate relays 21 and 22 with contacts 23 and 24, respectively, and elements 25 connected to tires X, contacts 20, 23 and 24. In addition, the device includes a control matrix 26 on tires 27 (X), 28 (Y) and 29 (Z),

auxiliary relays 30 with contacts 31, coordinated relays 32 and 33 with contacts 34 and 35, respectively, and elements 36 connected to tires X contacts 31, 34 and 35; Dnds 37, 38 and 39; Relay 40 switches off with contacts 41; Signal lights 42; Resistors 43. The buttons / are connected to matrix 15 by control lines 44, and Matrix 15 is connected to controlled objects 45 that have sensors 46 and 47 of state lines 48 control. Relay 40 is disconnected from the elements of the matrix 15 by lines 49. Each element 14 of the alarm matrix consists of an electrical relay 50 with contacts 51 and a resistor 52. Each element 25 of the control matrix consists of an executive relay 53 with contacts 54, a relay 55 controls with contacts 56, relay 57 delays with co-tacts 58, information relay 59 with contacts 60, resistors 61 and 62 and co-detector 63. Each element 36 of the matrix is coitrol from the primary relay 64 with coitacts 65. All device matrices have the same dimensions. same: then The children numbers are connected, respectively, to the common wires connected to the power source through the normally open control buttons and the voltage polarity switch. Turning on the object is done by pressing the / button. At the same time, relays 8, 10, 19 and 21 are triggered. Relay 8 with its co-tacts 9 and relay 10 with its contacts 12. Turns on relay 50, which contacts 51 blocks itself, turns on the signal lamp 42 through a resistor 43, and prepares a self-blocking circuit 64. contacts 20 and relay 21 their contacts 23 include a relay 53, which with its contacts 54 self-blocks through a resistor 61, turns on object 45, and prepares the operation circuit of relay 55. Object 45 begins to work out a given command. When this occurs, the contacts of the state sensor 46 are closed and the relay 55 is triggered. Relay 55 forms the second control circuit of the object 45 with its contacts 56, de-energizes the relay 53 and connects the relay 57 to the power supply. Relay 53 releases, the relay 57 is activated. Through the contacts 56 of the relay 55, a charge current of the capacitor 63 flows, which leads to the operation of the relay 59. The relay 59 connects through the isolating diodes 39 to the power supply of the relay 40 and via the isolating diodes 37 and 38 to relays 30 and 32, respectively. Relay 30 with its contacts 31 and relay 32 with its contacts 34 switches on relay 64, which blocks itself through coitacts 51 of relay 50 and shunts a resistor 43 to power the signal of lamp 42. As a result, the luminance of the lamp changes, indicating that the control lines 44 and 48 are working and about the development of a given command by the object. The relay 40 disconnects with its contacts 41 and breaks the power supply of the button /, due to which the possibility of a short source power supply cable being removed when the button is pressed at the same time as the Si relay activates. at the end of the charge of the capacitor 6, the coil of the relay is disconnected and relay 9, d2 and W release. After the command 4S of the specified command is opened, the sensor 4 / state and the relay OO releases, and the homing of the relays 8, W, 19 and 1 are connected to the power supply through the normally closed contacts 04 and o of the relay OJ and oh and the closed coitacts 58 of the relay having a deceleration on release. when the relays u, W, UU and 21 are operated, the relay i winding (J is shunted by a circuit made up of contacts i2 and y, line 44 of the unit and contacts 0, d, u4, 00 and o.) The tiO releases and exhausts the insulation of the relay 64. 51 and 00 in the sigalia lamp circuit are opened and the lamp goes out, indicating that the target has finished working on a given command. The release time of the relay 57 is equal to the sum of the response time of the relay 8 and the release time of the relay 50; response time of the relay 10 select At the same time, the response time of the relay 10 is set equal to the response time of relay 8. When relay 55 is released, capacitor 63 is discharged through resistor 62. De-energizing relay 57 sets the circuit to initial state. All elements of the remote control device are disconnected from the power source. 3 in conjunction with button 1 is designed to turn off the relay 53 (or 55) when it is necessary to turn off the control object at any time when the object performs a specified command (program). In this case, relays 8, 10, 19 and 21 are triggered, and the winding of relay 53 (or 55) is shunted by a circuit composed of coitracks 23 and 20 of relay 21 and 19. respectively, control line 44, button / and switch 3. Relay 53 (or 55) lets go. However, when the relay 53 is disconnected (or 55), it also releases the relay 50, since its winding is also connected with a circuit made up of the contacts 12 9 of the relay 10 and 8, respectively, the KEYS / and the non-switch .3. The failure of the relay 50 leads to the extinction of the signal lamp. The device diagram for remotely controlling the aggregate of objects is returned to the initial state. The proposed device eliminates simultaneous testing by several (or all) objects of the given commands when controlled along one line (and at the interconnection of switching on the objects); and independent shutdown of some objects in the process of working out by other objects of the specified commands; bringing the device circuit back to its initial state after the objects have been working with the specified commands; signaling about the state of controllable objects and about the health of control lines; independence of control of some objects from the state of other objects; reduction in the number of lines of uravleni.
