The invention relates to the field of information and computing technology and can be used as peripheral sensors in automated systems of operational control of discrete production in obtaining information about the workload of technological

Equipment.

The aim of the invention is to expand the information content of the device.

Figure 1 shows the functional diagram of the device; 2 is a memory block.

The device contains sensors 1, time relay 2, multiplexer 3, generator of 4 pulses, frequency divider 5, delay element 6, element 7, first 8 and second 9 pulse generators, first 10 and second 11 BAN elements, counter 12 and memory unit 13 (FIG. 2) g containing, for example, delay elements 34 and 15, demultiplexers 16 and P, counters 18, memory elements 19,

When the divider 5 frequency is selected from the corresponding area of the memory elements 19 and the strobe signal is generated from the BANKS 10 and 11 elements, the memory code 19 records the code from the output of the counter 129 which corresponds to the current shift time. And the code from the output of the counter-12 is entered every time to a new area of memory elements 19} which is defined by the corresponding counters 18, in which1 the sequence of equipment switching on or off is taken into account. The output as sensor 1 is connected via time relay 2 to the inputs of multiplexer 3,

The device works as follows.

In the initial state, the frequency divider 5 controls the addresses of the multi - core 3 to the memory block 13. The pulse generator 4 generates counting pulses for the frequency divider 5. In the absence of signals from the outputs of sensors 1, the corresponding time relays 2 are turned on and at the output of multiplexer 3, high levels of voltage are constantly switched from the outputs of time relay 2. If there is a high loss at the input of the element 7 and 7 from multiplexer 3, clock pulses pass from the first output of the generator 4;

owls The first pulse from the burst of pulses through each metering channel passes through the first element BANGE 10 and gates the entry in block 1 3 of memory of the counter code 12 (equipment disconnection moment), in which information about the current shift time is accumulated. The pulse shaper 8 provides a reliable blocking of subsequent pulses that pass from the output of the AND 7 element at a given address given by frequency divider 5. At the first input of the generator 4 pulses, a burst of pulses is formed, providing a complete polling by the divider 5 of the frequency of all the relays 2 times.

In this case, the second output of the generator 4 pulses passes — only one pulse. Thus, the pulse shaper 8 must delay the input signal for a time approximately equal to the period of the reference signal at the second output of the generator 4. At the same time, the signals do not pass through the second BAN 11 element, since the second pulse shaper 9 generates signals delayed by one the clock frequency of the reference frequency at the second output of the generator 4 so that they are reliably blocked by signals from the output of the element 7. When any sensor 1 is triggered, the corresponding signal is reset. The time relay 2 and the output of the element And 7 does not generate a pulse at this state of the 5 frequency divider. In this case, the output of the second element BANGE 11 passes a pulse from the output of the second driver 9 pulses during the previous clock cycle, memory block 13 is built, where the state of the counter 12 is recorded at the address corresponding to the code provided by the frequency divider 5, which corresponds to the connected multiplexer number 3 channels. The delay that the second driver of the 9 pulses must provide must also be approximately equal to the period of the reference pulses on the second output of the generator of the 4 pulses.

Thus, in block 13 of the memory, information is accumulated on the moments of switching on and off the equipment and, according to this information, at the end of the shift, for example, a computer can be used to make a photograph of the shift and more

fully characterize the workload of the equipment shop.
