(54) СИСТЕМА ДИСТАНЦИОННОГО КОНТРОЛЯ И УПРАВЛЕНИЯ КОМБАЙНОМ В УГОЛЬНОМ ПЛАСТЕ(54) SYSTEM OF REMOTE CONTROL AND CONTROL OF A COMBINE IN A COAL PLATE
I. I.
Изобретение относитс к горной промышленности н предназначено дл контрол н автоматического управлени горным комбайном в профиле пласта при различных режимах работы в забое.The invention relates to the mining industry and is designed to control the automatic control of a mining combine in a profile of a formation under various modes of operation in the bottomhole.
Известны.способы н устройства дл контрол н управлени горным комбайном по пласту, содержащие автогенератор высокой частоты с резонансным колебательным контуром , в который включены параллельно конденсаторный датчик порода-уголь, вл ющийс одновременно одним из плеч моста посто нного тока, н варикап, включенный в диагональ этого моста. К измерительному автогенератору и кварцевому генератору опорной частоты подключен смеситель, выдающий сигнал разностной частоты указанных генераторов через амплитудный ограничнте )|ь иа дискриминатор, который соединен с индикатором и входом системы автоматического управлени режущими орга иами выемочной машины {1).There are known methods for controlling a miner on a reservoir through a formation that contain a high-frequency self-oscillator with a resonant oscillatory circuit, in which a rock-coal capacitor sensor is connected in parallel, which is simultaneously one of the arms of a direct current bridge, a varicap included in the diagonal this bridge. A mixer is connected to the measuring oscillator and a quartz oscillator of the reference frequency, producing a difference frequency signal from the indicated oscillators through an amplitude limiter and discriminator, which is connected to the indicator and the input of the automatic control system of the cutting machine {1).
Известна также снстема дистанционного контрол н управлени комбайном в угдльиом пласте, содержаща датчики и устройство порода-уголь и регул тор; КонтрольAlso known is the remote control system for a combine in a flat seam, comprising sensors and a rock-coal device and a regulator; Control
границы раздела двух сред осуществл етс с помощью измерительных резцов (датчиков ), подключенных к устройству породауголь , которое вырабатывает сигналы о глубине внедрени режущих органов комбайна в пласт, использу различие констант днэлектрйческой проницаемости и диэлектрических потерь углей и пород, и передает их через индуктивную электропередачу в регул тор комбайна 2.the boundary between two media is carried out using measuring cutters (sensors) connected to the rock device, which generates signals about the depth of penetration of the combine's cutting bodies into the reservoir using the difference in dielectric constant and dielectric loss constants of coals and rocks, and transmits them through inductive transmission into combine controller 2.
Недостатками известиой системы вл ютс наличие одного режима работы комбайна - автоматнческого управлени режущими органами по гипсометрии без присечки породы почвы и кровли пласта, отсутствие информации у машиниста о глубиие режущих органов в угольном пласте, а также отсутствие дистанционного управленн комбайном.The drawbacks of the lime system are the presence of a single mode of operation of the combine - automatic control of cutting bodies using hypsometry without adhering rocks of the soil and roof of the reservoir, lack of information from the driver about the depth of cutting bodies in the coal seam, and the lack of a remote control combine.
