The teletransmission system controlled based on a single chip microcomputer, consisting in that the analogue signal of the controlled unit is fed through the receiver of the remote controller (OP) to the first input of the comparator (K), whose second input is connected with the output of the digital-to-analogue converter (C/A) controlled through the first port (P1) of the microcomputer (MK), whereas the output of the comparator (K) is connected to the first program tested input (TO) of the microcomputer, and additionally the microcomputer (MK) receives digital information on the state of the controlled unit to the interrupt bus (INT) and the second one of program tested inputs (T1); moreover, through the second port (P2) the microcomputer controls the control-alarm translation (TSA) and the address bus (A0, A1) of the parallel interface, and through the writing lines (RD) and reading lines (WR) controls the direction of information flow along the data bus (DB) connecting it with the parallel interface, whose first port (P1) is connected to the control keyboard (KS), whereas the second (P2) and the third port (P3) control the distributor system (R) and the optical signalling block (BSO).IMAGE
