Fig. 5 is an example of a memory block.

The device contains an information unit 1, a current time sensor 2 made, for example, in the form of a pulse generator with the Start and Stop inputs, the time interval distributor 3, the block 4 of adders and the memory block 5.

Input “Start of operation and input“ End of operation of information block 1 is connected to the control object.

The information block 1 is designed to transmit information about the need to reset the registers of block 5, reset the counters of the distributor 3 to the initial state, and to receive and transmit a signal about the beginning (ending) of the operation of the object.

The information block 1 contains a switch, a switch 6, a four-bit register 7 and an element 8.

Distributor 3 time intervals are designed to distribute the counted time interval into seconds, minutes, hours and contain delay elements 9 and 10 performed on triggers, binary counters 11-13 for counting seconds, minutes, hours performed on counting triggers, and AND 14- sixteen.

Block 4 adders is intended for

And then, at the second output of the information block 1, an impulse appears, which is fed to the input "Setting 3 time intervals to the initial distributor and then to the first installation inputs of six-bit counters 11 and 12 and p-bit counter 13 and sets them in the initial state: writes the unit to the third bits of the counters 11 and 12, after which their capacity becomes 60 and zeroes the counter 13, the capacity of which is equal to the number of hours counted.

The calculation of the time interval starts from the moment of arrival of the signal that the object begins to work at the input of element 8. At the zero position of register 7, one is recorded, and then at the first output of information block 1 a signal appears, which then goes to the input time and then to the "Distributor's 3 time interval counting input and counting input of counter 11. After the 60th pulse from the current time sensor 2 arrives, an overflow pulse appears on the first transfer output of counter 11, the th input of the counter 12 and the input of the element 9 delay. The delay time is equal to the time of reception of the pulse at the counting input of the counter 12. With you 45

An arithmetic summation of the time-40 steps of the delay element 9 impulse arrives at the second installation input of the counter 11 and sets it to the Initial state, as indicated above. After the next 60 pulses arrive at the counting input of counter 11 at the output "Overflow, another overflow pulse appears, which is fed to the counting input of counter 12 and to the input of delay element 9. A signal from the output of delay 9 causes the counter 11 to reset. The arrival of 60 pulses from counter II at the counting input of counter G2 at the output of counter 12 results in an overflow pulse that arrives at the counting input of counter 12 and the input of delay element 10. The delay time is equal to the reception time of pulse intervals, expressed in codes of numbers, and contains adders 17-19.

The memory unit 5 is intended for recording and long-term storage of time intervals counted in the previous turn-on cycles of an object.

Block 5 contains AND 20-22 elements, registers 23-25 executed on elements that permanently retain information after a power failure, first AND elements 26-28, and delay element 29.

The device works as follows.

Before the first measurement of the operating time of the object, the registers 23-25 of block 5 are reset. To do this, switch 6

information block 1 is set to 55 sa on the counting input of the counter 13. The signal from the position "Reset registers. At the same time, the unit 10 outputs the output of the delay element 10 to the third digit of the register 7, and the fourth installation input of the counter 13 and sets it to the initial state at the fourth output. After block 1, a signal appears that goes to the input "Resetting the registers of block 5 and then to the first inputs of registers 23-25 and zeroing them. The operation of resetting the registers 23–25 is not performed before the next one, by measuring them at intervals of time, but only in cases of need (change of object, malfunction, development of a guarantee resource, etc.).

And then, at the second output of the information block 1, an impulse appears, which is fed to the input "Setting 3 time intervals to the initial distributor and then to the first installation inputs of six-bit counters 11 and 12 and p-bit counter 13 and sets them in the initial state: writes the unit to the third bits of the counters 11 and 12, after which their capacity becomes 60 and zeroes the counter 13, the capacity of which is equal to the number of hours counted.

The calculation of the time interval starts from the moment of arrival of the signal that the object begins to work at the input of element 8. At the zero position of register 7, one is recorded, and then at the first output of information block 1 a signal appears, which then goes to the input time and then to the "Distributor's 3 time interval counting input and counting input of counter 11. After the 60th pulse from the current time sensor 2 arrives, an overflow pulse appears on the first transfer output of counter 11, the th input of the counter 12 and the input of the element 9 delay. The delay time is equal to the pulse reception time at the counting input of the counter 12. At the output of the delay element 9, the pulse arrives at the second installation input of the counter 11 and sets it to the Initial state, as indicated above. After the next 60 pulses arrive at the counting input of counter 11 at the output "Overflow, another overflow pulse appears, which is fed to the counting input of counter 12 and to the input of delay element 9. A signal from the output of delay 9 causes the counter 11 to reset. After the 60 pulses from the counter II enter the counting input of the counter G2, the output of the counter 12 appears at the output of the counter 12, which arrives at the counting input of the counter 12 and the input of the delay element 10. The delay time is equal to the pulse reception time at the counting input of the counter 13. The signal from the output of the delay element 10 is fed to

the second installation input of the counter 13 and sets it to its original state. The process continues throughout the entire time period calculation period. Upon receiving a signal from the object about the end of work in the second bit of the output register 7, information block 1 records one, after which a signal appears at the third output, which goes to the input of the Sensor Stop 2 of the current time and stops its operation. The signal from the third output of the information block I simultaneously enters the inputs "Resolution of the summation of the distributor 3 time intervals and block 5. The signal from the input" Resolution of the summation of the distributor 3 intervals of time goes to one input
