RU1830625C - Two-wire system of supply and information transmission - Google Patents

Description

a body 19 and a second stabilizer 20. The coding unit has one input and three outputs. A potential code is input to the coding block. At the outputs, FM and FM codes and clock pulses are generated. The code generator can be implemented on chips 134, 133, 564 series. A potential code from the information block, clock pulses and pulses of the beginning of measurements, generated in the coding block, are received at its input. From the output of the FM and FM coding block, the signals are sent to the key bases - transistors 9 and 8. Sync pulses from the output of the coding block are sent to the input of the information block. The clock generator 17 can be implemented on the 133, 134 and 564 series. The power amplifier 19 can be implemented on 544UD2, 1N1622, 1NT251.

When a constant voltage is supplied from the source 4 to the transmitting side of the device, a supply voltage is supplied to the second stabilizer 20 to the second stabilizer 20, and it begins to generate a phase-shifted code of zeros, which is a meander following with the frequency of information transmission. This signal is fed to the base of transistor 9, and the inverse signal is sent to the base of transistor 8. When an inverse FM signal arrives at the base of transistor 8, the transistor opens, and the capacitor 11 initially discharges through the circuit: the primary winding of the first transistor 10, collector-emitter - the junction transition of the first transistor 3, the second lining of the capacitor 11. When a direct signal arrives at the base of the second transistor 9, the transistor opens, the current flowing through it charges the capacitor 11 along the circuit: collector-transistor junction transistor Ora 9, the primary winding of the first transformer 10, a capacitor 11 and a minus of a constant voltage power supply 4. The alternating charge-discharge current of the capacitor 11 excites in the secondary windings of the transformer 10ED € (see Fig. 2d), on which it is converted to a stabilized constant voltage of the unit nodes.

Digital information from the information block 12 is fed to the input of the encoding unit 16. In accordance with the transmitted code (Fig. 2a), the encoding unit 16 generates an FM signal that controls the transistors 8 and 9. Phase-manipulated current pulses (Fig. 2b, c) two-wire lines create voltage pulses in the primary winding of the second transformer 5 on the receiving side of the device, which enter the receiving unit 6 (Fig. 2e).

The proposed two-wire system. power and information transmission

in comparison with the prototype, the advantage expressed by B is to increase the efficiency of the system by reducing the losses associated with the transmission of information, because information is transmitted by current passing

through the primary winding of a pulse transformer, in the forward direction and there is no idle current in the intervals between current packages, a voltage Converter, including

transistors 9.8. the primary winding of the transformer 10 and the capacitor 11, work with high efficiency, because works in a pulsed mode.
