transmit and receive the digital signals of the control room radio monitoring system of automation unguarded crossings

摘要

Proposed from all crossings controlled transfer only one Overheads and the CPU selection crossings performed using triggers, to the clock inputs of which signals are inputted from the output decoder connected to the multivibrator through the meter. Technical and economic effect is the release of PM 2 ⁿ -2 codified, where n - the number of monitored crossings, necessary for specifying fault on each moving and exchanging information between the controller and the CPU repairman automation.
