Task 3.6. To determine the total number of channels connection, the
condition of which can follow an operator, if under the terms of the process control
operator must indicate failure of channels communication not more than 5 s after
its creation for such organization of information margine: it is planned to install
scoreboard display channels communication in the form of identical elements
alarm, represented by indicators with measurements axb mm (initial data is shown
in Table 3.2), the distance between them is L ind. mm (initial data is shown in Table
3.2). At channel failure, is turned audio signal and flashing light is illuminated by
the frequency of flashes f=6,5 Hz. Operator is allocated at a distance L cm (initial
data is shown in Table 3.2) from scoreboard. Angular size of zone indication 10 o
o
(tg 5 =0,085). Evaluating time of flash of indicator makes is t ,s (initial data is

shown in Table 3.2)
