The invention relates to automation, in particular, to devices for determining the operating time of printing presses, and can be used in devices for recording the operating time of technological equipment in various sectors of the national plant.

The aim of the invention is to improve the accuracy of the device.

Figure 1 shows the functional diagram of the device; FIG. 2 is a temporary diagram of his work.

The device contains a generator 1 15 mpulsov5 first element And 2, the first counter 3, the second element And 4, D - trigger 5, block 6 of the initial installation, the sensor 7, the key 8, the delay element 9, the second counter 10.

The device works as follows.

When the power is turned on, the setup block 6 zeroes the first counter 3 and sets the second counter 10 to one, the signal from whose output sets the one to D-flip-flop 5, the signal from the output of D-flip-flop 5 prohibits the passage of pulses from the generator jg of the torus 1 pulses to the first counter 3. After the start of operation of the technological equipment, the output of sensor 7 is the appearance of pulses that are converted by key 8 into pulses that control the logical part of the device.

The first pulse, coming from the output of the key 8 to the second input of the D-flip-flop 5, does not change its single state, besides, the first pulse through the time determined by delay element 9 sets the second counter 10 to zero state. Pulses from generator 1 begin to flow through the element I4 to the counting input of the second counter 10. The counter 10 is designed in such a way that its time is over. the completion of pulses from zero to one state is equal to the period of operation of the sensor 7 cycles of equipment operation with the minimum operating time. equipment speed k

Suppose that the speed of the equipment is below the minimum rby speed. In this case, before the sensor 7 generates the second pulse, the counter 10 will be filled, at its output the signal level will become equal to

logical unit. This level, arriving at the first input of the D-flip-flop 5, confirms the single state of the D-flip-flop 5, and entering the inverse input of the And 4 element, blocks the counting input of the second counter 10. The impact on the device of the second pulse is similar to that of the first.

Suppose that the speed of the equipment is above the minimum operating speed. In this case, by the moment the second pulse arrives at the second input of D-flip-flop 5, the counter 10 is not filled at its output and, accordingly, at the input of D-flip-flop 5, the signal level corresponds to a logical zero. Consequently, the second pulse will transfer the D-flip-flop 5 to the zero state, which will allow the passage of pulses through the AND 2 element to the first counter 3, which will begin to calculate the equipment operation time. After a time determined by the delay element 9, the counter 10 will be reset,

By reducing the speed of the equipment below the minimum working. the speed. the counter 10 is filled; at its output, the level of the logical unit, which, on the first input, will translate the D-flip-flop 5 to the single state, is output. The signal from the output of D-flip-flop 5 will prohibit the passage of pulses through element I2 to the first counter 3. The countdown of the equipment operation time will stop. The pulse generated by the sensor 7 will reset the second counter 10, but the state of the D-flip-flop 5 will not change.

Thus, the presence of new functional elements and connections makes the device more accurate, since the operation time of the process equipment is counted only if the equipment operates at a minimum operating speed.
