Description

The invention relates to automation and can be used to measure and record the duration of operation of the actuators.

The purpose of the invention is to expand the scope by measuring the duration of the operation of the actuators.

The drawing shows the functional diagram of the device.

The device contains analog sensors 1, block 2 keys, analog-to-digital converter 3, switch 4, buffer register 5, block 6 of memory, time sensors 7, group of elements AND 8, generator 9 of pulses, frequency divider 10. element 11, distributor 12 pulses, formers 13 pulses of reset, counters 14, element OR 15.

The analog-to-digital converter 3 contains a null-body 16, a code-voltage converter 17, a control register 18, a shift register 19.

The device works as follows.

The supply voltage is continuously applied to the generator 9 pulses of the reference frequency, divider 10, element 11 and elements 8, drivers for 13 pulses and counters 14 pulses. The remaining blocks are de-energized and the supply voltage to them is supplied during measurements of the readings of the analog sensors and the recording of information in the memory block 6 (device operation time). Registration of information on the operating time of the actuators is performed during the operation of the entire device.

The frequency divider 10 generates a signal with a pulse following period corresponding to the measurement cycle (1.2 or

4 min depending on the version), and the pulse duration corresponding to the time of measurement and recording of information. At the other output of the divider, the clock frequency of the meter (50 Hz) is formed. At the output of the element 11, a signal with a frequency of 50 Hz appears for the time of measurement and recording and is fed to the buffer register

5 and register 19 shift. When any actuating element is triggered, the output of the corresponding time sensor 7 appears logical. "1, element 8 transmits pulses of generator 9 to the input of the corresponding counter 14, the number of pulses recorded by counter 14 is proportional to the duration of operation of the actuating element during the time between device response times. During operation of the device, the first analog sensor 1 from the 2-key block is first connected to the null-organ 16, to the corresponding control input of which is fed

the signal from the output of the distributor 12 pulses.

Null-body 16, the converter 17 code-

the voltage, the control register 18 and the shift register 19 constitute an analog-to-digital converter 3 for one-bit equilibration, which measures the output voltages of analog sensors with a clock frequency (50 Hz) set by frequency divider 10. Simultaneously with the process of measuring the value of the signal of the first analog sensor, information is recorded in the memory block in the form of a positional ten-bit binary code. At the end of the measurement, the pulse distributor 12 is switched over by the signal of the cyclic register 19 of the shift and the next analog sensor is connected. The measurement and recording process is repeated several times (by the number of analog channels). Then the first channel for measuring and recording the duration of operation of the actuators is connected. At the corresponding output of the distributor, 12 pulses appear

logical 1, the switch 4 connects to the information inputs of the buffer register 5 the outputs of the first counter 14.

0

The pulse shaper 13 with the appearance of a logical "1" at the corresponding output of the pulse distributor 12 generates two short pulses that appear with a delay. The first pulse of the drivers 13 through the element OR 15 is fed to the input of information input in a parallel form of the buffer register 5 and the code of the first counter 14 is written into the buffer register 5. The second pulse of the drivers 13 resets the counter 14 to the zero state, which continues to count the generator pulses ,

0 if at the output of the corresponding digital state sensor of the actuating element there is a logical "1. Further, with a clock frequency equal to the frequency of measuring and recording the values of analog sensors

5 (50 Hz) inputted to the buffer register 5 from the AND element, information is recorded in the form of a serial positional binary code in the memory block, for which the output of the buffer register 5 is connected to the memory block 6. At the end of registering the information of the first counter 14 by the signal of the shift register 19, the distributor 12 pulses are switched to the next state. The registration process is repeated several times according to the number of measurement channels for the duration of operation of the actuators. Upon completion of registration, the supply voltage is disconnected from a part of the device.
