It is possible to implement a computing device on the basis of serially running computer microprocessors.

The control unit (Fig. 2) contains

switch 24 operating modes,

The switch of 25 numbers of standards, as well as the Start 26 and Reset buttons 27. Contact Adjusting switch 24 is connected to the inputs of key 4 and logic element AND 28, and the Contact Work with the inputs of key 5 and logic switch AND 29. The contacts of switch 25 are respectively connected to the inputs of the keys 16 and 17. The output element And 29 through the element ШШ 30 is connected to the encoding converter 2. The second input of the element OR 30 is connected to the output of the element. And 28. The inputs of the element And 28 are connected to the output of the generator 31 clock. pulses and with the release of the trigger 32, and one of 3

The trigger trigger 32 is connected to the Start button 26, and the second input to the output of the counter 33 is the number of measurements, through the logical element OR 34. The counting input of the counter 33 to the number of measurements is connected to the output of the And 28 element. The Reset button 27 is connected to the Reset of the counter 33 input and also with the input of the element OR 34 and with the input of the counter 3.

The device works as follows.

The switch 24 of the operation mode of the control unit 6 is set to the Setting mode. In this case, key scheme 5 is closed, and key scheme 4 is open. At the first input element And 28 sets a single signal.

1 Registers 11-14 are entered in the digital code, respectively, of the sizes of the first and second standards, the interval of the sorting group, the size of the size corresponding to the border of the zero and first sorting groups (lower limit of tolerance). Then the standard with the size corresponding to the first sorting group is placed on the measuring position of the device. Switch 25 is shifted to position 1 reference. By pressing the Start button 26, the circuit is activated. At the same time, the trigger 32 enters a state in which a single signal appears at its output, which is fed to the second input of the And 28 element. The clock pulses from the generator 31 begin to flow through the AND 28 and OR 30 elements to the coding converter 2 and at the same time counting input counter 33. There is a measurement of the standard. The number of measurements, n, is determined by which output of the counter 33 is connected to the input of the OR 34 element. After n measurements, a signal appears at the output of the counter 33, which sends the trigger 32 to the initial state through the OR 34 element. The passage of clock pulses is stopped and the circuit is stopped. After each measurement, the value of the size of the standard, converted by the measuring-coding converter 2 into a code, is summed up in counter 3. From counter 3 via key skem 4 information is transferred to block 15, in which the contents of counter 3 are divided by the number of parameters. record 94513

Appears at the first entrance to the block 18 subtraction. After that, the Reset button 27 is pressed and the counters 3 and 33 are reset. Then the switch 25 is shifted to the standard and the second standard is set to the measurement position, preferably from the last dimensional group. The operations are repeated in that

In the same order as in the first case, only the information in block 15 of division is now transmitted through key circuit 17 to the second input of block 18 of subtraction. Multiple measurements

The 5 standards are made in order to increase the reliability of the measurement - standards, which provides greater tuning accuracy.

In subtraction unit 18, the measurement result of the first and second reference is subtracted. The sizes of the standards are recorded in registers 11 and 12. The difference of these values is calculated by subtractor 20. Thus, the value of the difference of the measurement results in the subtraction unit 18 is applied to one input of the divider 19, and the value of the difference of the sizes of the standards to the second input.

30 I

as a result of dividing the first difference by the second, at the output of block 19, the value is formed, equal to the actual gear ratio K of the measuring system. In register 13 recorded interval size group. The magnitude of the interval in multiplier 21 is multiplied by the gear ratio K and the result is transmitted as a constant term to the adders 23..

In the multiplier 21, the lower limit of the tolerance field recorded in the register 14 does not have a gear ratio K, as a result of which the output of the multiplier 22 is the first setpoint, which is recorded in the setting register 9, as the boundary between the scrap and the first sorting group.

5 In the first adder 23, the addition of the first setup is made with a constant term, as a result of which in register 9 the second setpoint is set corresponding to the upper

55 border of the second sorting group. In the second adder, the second setpoint is added to the constant term and in register 9 the third setpoint is set, etc. Device setup is done. The switch 24 is moved to the Operation position. The Reset button 27 zeroes the counters 3 and 33. The controlled part is placed on the measuring position and the Start button is pressed. The signal through the element And 29 is fed to the coding
