Description

The invention relates to automated means of controlling machine load times; for the first time, it can be used, for example, to determine the duration of operation of mannins with predetermined levels of load quantization and on-line consumption of mapped energy, i.e. but- histogram of loads of mania in the conditions of operation.

The aim of the invention is device tampering.

The drawing shows a block-c. Schema of the proposed device.

The device consists of sensor 1, the output of KOTOpoi o through connected busbars 2 and filter 3 is connected to the first switch of the comparator 4, the second input of the Topoi o is connected to the output n) of the generator D) code-voltage, output komnaratora 4 nod-k.iochen to the entrance of the nerves on the counter 6 |, 15khod which is connected to the nerve input of the second counter 5; n the output of the i-generator 7 im- iy: ibcoB, the input of the nerve counter 6; connected to the BTCjpbiM input of the second counter 6o, the output of the current generator 8 is connected to the anodes of the integrators 9, ..., 9ts, the first input of the element IK) is connected to the output of the second counter 6-2, and the second output of the element ANDI) is connected. to 1 input of generator 8 of current, outputs iiepBoixj of counter 6i with 2 but JI connected to the corresponding level of correspondent of Jun1, their inputs of converter 5, voltage code and switch And, respectively, analogue inputs of switch 11, 11 with the cathodes of the corresponding integral 1) ator () in 9i9 ,, the analog output of the switch 1 1 is connected to the feedback input of the current generator 8, and the output 2 of the second sensor 6--2 is connected to the second input of the second counter 6--2.

The operation of the device is as follows.

When enabled: 1 controlled monitory of the signal — from sensor 1, via a rectifier 2, filter 3 to the first input of comparator 4. Tekup1.e, the signal is loaded, 1a of the unit, 1 load of the mains. At this time imiu. from the output of the generator 7: 1nsov just on the 1st input of the counters 6i and BL). (1chik 6i equals the switch I, which alternately connects one of the integrators 9, ..., 9 "to the current generator 8. (1rchik 6 | also corrects the transformer Γ), B1 1, I correspondently) H1.

This code is the voltage on the second comparator 4. I compare it to the voltage at the output fu 3 h 3.

When the output voltage c) and: 1B 1-ra 3 of the on-voltage voltage is exceeded, the comparator 4 issues a signal to prohibit counting by the counter 6i and the signal of the discharge of the voltage of the generator of the current 8 to the first |; II and transform. H 5 is determined by the state of counter 6 |.

At the end of 2 pulses, the counter 6 outputs a signal. To the second ecumenter AND 10. including the current generator 8, and through one of the integrator 9i, ..., 9 .., a current pulse from 1 is completed |: 1a 8 current.

At tip 2 imnu.chsov counter 6-2 resets to "zero counters 6 | and 6, and the cycle, and 3..

If yes, if the load of the mainframe does not fit, then Hirrei paTOp will go even. Mnuysnogorogonnoy form and integrator buds show the time of work1 of the mainline with this load. In this case, the device (FicciitiyeT), the operating time of the mother with the levels 5 set on the transducer nomoni.yu;) is narrow.
