THE TRANSMITTING CASCADE IN THE TIRE ASSEMBLY OF THE BUS NETWORK TO PRODUCE THE APPROPRIATE SIGNAL OF THE BIT SIGNAL AND THE METHOD OF PRODUCING THE BIT SIGNAL FROM THE SENDED SIGNAL

摘要

1. The transmitting stage in the bus node of the bus network, especially in the bus node of the EIB network, which is connected to the bus line (Bus +, Bus-), to generate a corresponding signal to be transmitted, which has a sequence of transmitted pulses, a bit signal, which for each transmitted pulse consists of: an active pulse, which has a duration Δt = tt, and t indicates the beginning of the active pulse, a t - the end of the active pulse, and the depth U of the pulse following the active pulse of the equalizing pulse, with: circuit (A) for generating ki of an active pulse, by a circuit (B) for generating an equalizing pulse, and by at least one control circuit (C) for generating a transmitted signal (U), at least by a circuit (A) for generating an active pulse, wherein the depth (U) of the pulse the active pulse is set by the specified reference voltage (U), which is independent of the value of the constant component of the voltage of the bit signal, while the circuit (A) for generating the active pulse is made in such a way that it keeps the depth (U) of the pulse of the active impulse constant due to negative feedback on the variable component of the voltage of the bit signal, characterized in that between the voltage-carrying part of the bus line (Bus +) and the voltage node (U), a capacitor (C1) is connected, and the voltage node (U) forms the selection of the voltage supplied by the reference voltage (U) of the circuit (U, R1, R2) of the voltage divider, which through the protective resistance (R3) is applied to the base of the transistor (Q1), which is part of the control circuit (Q1, Q2) of the transmitting transistor (Q3), and the resistance ( R1, R2) voltage divider circuits
