Abstract

The invention relates to the field of process signaling and can be used to organize the monitoring of the state of objects of continuous transport, such as conveyor lines in coal mines. The aim of the invention is to expand the scope of use due to the possibility of using for monitoring the state of remote objects. The goal is achieved by the fact that on the glass of the dial gauge 4 photo detectors are mounted in the holder-cage, which perceive changes in the intensity of the light reflected from the scale of the dial gauge 4 when its arrow moves. The signal of photodetectors through the signaling cells 6 comes to the indicators 10. When the connection between the memory elements 9 of the subsequent signaling cells 6 with amplifiers 8 of the subsequent signaling cells 6 is interrupted, switching on the next indicator 10 causes the forerunner to switch off. 1 hp f-ly, 3 ill.

The device works as follows.

In the initial state, all sensors 3 of the control are disconnected; the arrow of the dial indicator 4 is at zero, the photo detectors 7 placed in the holder cage 13 are mounted on the glass 14 of the dial indicator 4 at the places corresponding to the position of the arrow with a given number of conveyors turned on. Photo detectors 7 signaling cells 6 are open, from photo detectors 7 are fed to the input of amplifiers 8. At the same time, at the output of elements 9 of the memory of signaling cells 6

ABOUT

When the control object is turned on, the arrow of the arrow indicator 4 moves to a new stable position and blocks the flow of light reflected from the scale of the arrow indicator 4 and arriving at the input of the photo receiver 7 of another signaling cell 6. In this case, the signal of logical 1 from the output of the amplifier 8 of the signaling cell 6 is fed to the input of the reset element 12, where it produces a signal in the form of an impulse to reset the information previously recorded in 25 elements of the memory of all 6 signaling cells. This signal at the output of all the elements of the 9th memory of the logical O signal appears. Due to the arrow of the pointer indicator 30 of the torus 4, the luminous flux currently arriving at the input of the photoreceiver 7 corresponds to (signaling cell 6 of the signal, memory element 9 When this cell goes back to a state where the signal of logical 1 is present at its output, and the indicator of this alarm cell 6 is turned off. In addition, the signal of logical 1 from the output of element 9 of the memory of the alarm cell b is fed to the input of amplifier 8 The alarm signal cell 6, as a result of which element 9 and this alarm cell 6 enter the logical 1 state. When the memory element 9 arrives at the previous alarm 6 cell 6, the signal of the logical 1 turns on the indicator of this alarm cell 6, and the signal 50 is turned on The indicators of 10 alarms 6 provide information that the trace of a lean object is on. If the signal of the indicators of the previous alarms 6 alarm when the next
