FIELD: mining industry, particularly, automation of tunneling complexes control. SUBSTANCE: automatic control system has successively connected optical direction setter, electric modulator, diaphragm and photoelectronic detecting device, two units of signal selection, two current switches, busbar shaper unit, voltage switch, analog-to-digital converter, multiplexer, univibrator with logical input, one-shot multivibrator, master oscillator, interface, computer and transducers of roll angle, moving out of hydraulic jacks and feeler cutters and also transducers of moving out of lining placer manipulator members. Busbar shaper unit consists of six buffer registers. Photoelectronic detecting device consists of two multicell photodetectors in form of photocells combined by system of vertical and horizontal busbars. Design of signal selection unit is offered. EFFECT: higher reliability and efficiency of control of mechanisms of shield moving and support installation of tunneling complex. 2 cl, 3 dwg |
