Description

The invention relates to computer technology and may find application in automated systems for quality control, grade determination, categories, and the like.

The purpose of the invention is to expand the class of tasks to be solved.

Functional diagram of the device is shown in Fig. 1. The device contains blocks for setting indicators 1i, comparison blocks 2c, each of which includes registers 3,4 and a comparison circuit 5, the first 6j and second 7j of the group of elements And, the first 8j and second 9j of the group of delay elements, input 10 of the device start, outputs 11 and indicative output 12 0 TGt, j 1, p, where t is the number of controlled indicators of the object, p is the number of quality categories).

Before deciding the value of the PI Object Quality Score. I 1. m are entered in the corresponding blocks of the task of indicators 1i, I - 1, t, and in registers 3 and 4 of the comparison blocks 2ij are entered, respectively, the values of the lower PIJH and upper Pij8 of the boundaries of the range of values of the {th quality indicator (I 1, t ) for the j-th category of quality of objects (j Т7п).

The solution begins by supplying a logic level signal to the device trigger input 10. The signal from input 10 is fed to the combined reading inputs of parameter setting units 1i, I, the combined reading inputs of comparison blocks 2c, I 1. m and to the inputs of delay elements 8i and 9i. With outputs of blocks 1 | the values of the i-th quality indicators are sent to the information comparison of 5 comparison blocks 2ts, j «1, p. From the reading inputs of the comparison blocks 2c, I 1. m the signal goes to the reading inputs of registers 3, 4 of these blocks and the values of Rsn and Rtsv from their information outputs (L

are fed to the information inputs of the comparison circuits 5. After a delay time n sufficient to read the information and the comparison circuits to operate, a signal appears at the output of the delay element 9i. From the output of the delay element 9i, the signal is fed to the combined control inputs of the comparison blocks 2c, i 1, m. From the control inputs of these blocks, the signal is fed to the control input of their comparison circuits and, if RCI PI Rive. then at the output of the comparison circuit 5 of block 2c, a signal of the logic unit level appears, which is fed to the corresponding input of the And 6i element. If the signal of the level of the logical unit goes to all the inputs of the And 6i element, that is, if the values of all indicators satisfy the requirements of the 1st quality category, then the signal of the level of the logical unit appears at the output of the element And b1, from where it goes to the inverse input element And 7i and the output of the device 111. The presence of a signal at the output 111 indicates the conformity of the quality indicators with the requirements of the first quality category, and the signal at the inverse input of the element And 7i excludes further operation of the device.

If at least one of the PI quality indicators does not meet the requirements of the 1st quality category, then the signal does not arrive at the inverse input of the And 7i element and, when the element arrives through the delay time rz n, the signal from the output of the delay element 8i , a signal appears at the output of AND element 7. The next work step begins, at which, similarly to the first step discussed above, the conformity of the values of quality indicators of the 2nd quality category, then the 3rd category, etc. is checked.

If the values of the quality indicators do not meet the requirements of any of the n possible quality categories, then this

signals the appearance of a signal of the level of a logical unit at the characteristic output 12 after a time ny after the start of the device.

Thus, the proposed device for a finite number of steps provides automatic determination of the quality categories of objects.
