The control current of these switches must be calculated taking into account the shunting of the maximum input current, determined by the presence of all the above-mentioned input signals.

Claims

The drawing shows a schematic diagram of ycrp icTBa. The input buses 1 through the resistors 2 and diodes 3, 4 are connected to the LED-diode (optocouplers) 5, 6 optocouplers. The circuit also contains the optocoupler 7, decoders 8, control unit 10, matrix 11, delay unit 12, capacitor 13, optroces 14 , resistors 15, diode 16. The device operates as follows. In the initial state, on all outputs of the decoder 9 there is a signal 1 (high voltage level Eg), and on all outputs of the decoder 8. - signal O (low voltage level). As a result, all the optocouplers, (optocouplers) 6 are closed, and from the optocouplers (optocouplers) 5, those in which there are at least one input switch that is through the input buses 1, adjacent to the vertical array 11, are open. diodes 16, the limiting resistor 15 excites the optocoupler pair 14. The latter allows the corresponding optocoupler 5 to open, and therefore all vertical and horizontal buses of the matrix 11 are in the initial state under low voltage E. The selection of the signal for polling is accomplished by the unit control 10. For this, the control unit first generates a signal O at the corresponding output of the decoder 9, which creates conditions for charging the capacitors 13 connected to the selected vertical bus of the matrix 11 from the closed input lines 1. C Then, after a time determined by the full charge of the capacitors 13, the delay unit 12 outputs a signal to the decoder 8 to select a horizontal matrix bus. A signal 1 appears at the corresponding output of the decoder 8. If the signal is selected and the input bus 1 of the selected signal is closed, the voltage of the capacitor 13 through the isolating diode 4 and the diode of the optocoupler 6, the open output of the decoder 8, creates current through the optocoupler T This current opens the optocoupler pair 7, and from its output to the control unit 10 a pulse signal is received from the voltage E, galvanically developed with the voltage E. When the input bus 1 of the selected signal is open, the current through the optocoupler 6 and 7 does not leak will be and sig al to the control unit 10 does not arrive. Due to the introduction of chains consisting of groups of diodes 16, resistors 15 and optocouplers 14 with a large number of input sensors (in large systems at the same time, usually a small number of them are locked), the device allows you to process information about less energy consumption, which significantly improves thermal mode of operation, increases efficiency.
