Description

The invention relates to devices for monitoring and recording equipment operation and can be applied to dispatcher and automatic production control systems.

The aim of the invention is to increase the reliability and accuracy of operation of the Device.

The drawing shows a block diagram of the proposed device.

The device contains a sensor, 1 product release, a generator of 2 time intervals, a discriminator 3 and 4 time intervals, memory elements 5 and 6, elements 7 and 8, an operation time indicator 9, a rhythm disturbance indicator 10, a time indicator 11 simply.

The first discriminator of 3 time intervals contains the address pause 12, the counter 13 and the comparison element 14.

The second discriminator 4 comprises a pilot 15, a pause, a counter 16, and a reference element 17.

The signal from the sensor 1 product to the first inputs of the counters 13 and 16 discriminators 3 and 4 time intervals and elements 5 and 6 and holds them in the original (zero) position at the time of processing the controlled product. At the output of the first memory element 5, a signal is generated, which includes an indicator 9.

At the end of the signal from sensor 1, the elements 5 and 6 of the memory and the counter 16 of the second discriminator 4 remain in the original State, and the counter 13 of the discriminator 3 under the influence of the signals of the generator 2 time intervals begins to count the pause time between adjacent products. When the pause time in the counter 13 is reached, the value specified by the pause setting unit 12 at the output of the comparison element 14 will generate a signal that will turn the first memory element 5 into state 1. At the same time, the indicator 9 turns off and the rhythm disturbance indicator 10 turns on 7 And the pulses of the generator 2 will start to pass to the input of the counter 16 of the second discriminator. minator 4. Counter 16 will count down the time before comparison of the counter code 16 with the code specified by the unit 15 of the standard rate violation rate (above which the rate violation

read by equipment downtime). At the time of the code comparison, the output signal of the comparison element 17 is set to the second memory element 6 in state 1, in which the pulses of the generator 2 will start to pass through the element 8 AND for time reference simply to the time indicator 11 simply.

The countdown will simply continue to the next signal from the sensor 1 of the release of products, with the arrival of which the device returns to its original (zero) state, and all the described processes are repeated.

If the signal from sensor 1 arrives at a different (earlier) time of the described processes, the device will start repeating the considered processes from now on.

In the device, a signal Violation of the rhythm at the input of the indicator 10 is formed under the condition that the value of: a predetermined pause between products with the value of the working (current) pause

the measurement of which begins immediately after the disappearance of the signal from the sensor 1 of the launch of the product. If the actual (current) pause is less than the specified pause, then the signal 10 at the input of the indicator 10

missing. Similarly, the formation of the signal is simple.

Thus, the device has an increased reliability and accuracy in determining the moments of rhythm disturbance and the beginning is simple, and also allows you to more accurately determine the total downtime, regardless of the size between the products, which provides the device with more

wide area of use.
