Description

(54) DEVICE FOR ADMISSION CONTROL AND CLASSIFICATION OF PARAMETERS The known device allows for a qualitative assessment of an object characterized by many parameters, each of which has only one tolerance, while many parameters are characterized by several tolerance classes with non-overlapping tolerances. This is a disadvantage of the device. The purpose of the present invention is to increase the reliability of the control. The purpose of the in-device is achieved by introducing a class allocator, a memory block, an AND block and a counter, and the first trigger is connected through the class distributor to the first inputs of the AND block, the first distributor of classes is connected to the output of the pulse distributor and the first output is with the first inputs of the memory block, the first outputs of which are connected to the second inputs of the block of elements I, the output of which is connected to the first input of the counter and with the second input of the delay unit, the second inputs of the class distributor c, the memory unit and the counter are connected to the fifth output of the control unit, the third and fourth inputs of which are connected to the second outputs of the memory unit and to the output of the counter, respectively, as well as the fact that the switch is inserted into the device, the second trigger, the single pulse generator and an impulse generator, with the first input of the second trigger connected to the output of the class distributor, and the output to the first inputs of the pulse generator and switch, the second input of which is connected to the output of the pulse distributor, the third input to the third you by the memory block moves, and the output from the input of the single pulse generator, the output of which is connected to the second input of the pulse generator, and the fourth input of the switch and the second input of the second trigger are connected to the fifth output of the control unit, the fifth input of which is connected to the output of the pulse generator. The drawing shows a block diagram of a device that contains the control unit I, the control object 2, the parameter meter 3, the decoder 4, the block for specifying the tolerance field 5, the element 6, the first trigger 7, the block. forming gradations of tolerance field 8, pulse distributor 9, delay block 10, class distributor 11, memory block 12, AND 13 block, counter 14, second trigger 15, switch 16, single pulse shaper 17 and pulse generator 18. Consider object monitoring characterized by many parameters .A (, .Ai, ... A, each of which has m classes with non-overlapping fields. In this case, the control object can be rated as "suitable only if all its parameters correspond to a strictly defined class. In addition, optimal In terms of speed, the control will be if, after establishing the fact that the AI parameter corresponds to one of the m classes, the control of the subsequent parameters Dg ... And aus1: 1 is only in this class, and the rest of the mI class sections for each of the parameters Aa, ... A5 is not monitored. The device as a whole works as follows; Block I provides the flow of the monitored parameters of the control object 2 to the parameter meter 3. The measured value in the pulse code form enters the decoder 4 and after conversion in it the required numbering system enters block 5. If the actually measured parameter value corresponds to the tolerance field of the class being monitored, then all signals arrive at the input of element 6 and it triggers, and its output signal transfers trigger 7 to the unit state. Trigger trigger is a sign that the parameter corresponds to the tolerance of this class. The number of plots for each class of any parameter is specified in block 8, and their counting is in the distributor 9, which is designed as address counters, each of which is intended for counting a certain number of participants of the CCII. After reading the plots of each of the classes, the distributor 9 outputs a signal to the distributor of classes 11, which can be made in the form of an electronic or mechanical switch and switching. With each pulse from the distributor 9, the distributor 11 connects the input of the next memory element of the block 12 to the output of the trigger 7. If the parameter Aj corresponds to the tolerance of this class, the memory element corresponding to it will fix “1 trigger 7. The potential of the latter will also come through the distributor 11 to the first input of the corresponding element And block 13. The high potential of the memory element of block 12 will go to the second input of this element And block 13 and will be present at it until the end of the control. If the following A parameters correspond - AL, .. As - to the given tolerance class for the second input of element I of block 13, through distributor II, signals from trigger 7 are received. As a result, this element outputs a signal to input “delay of block 10”. In this case, the unit 10 will not work. At the end of the control of the tolerance classes of each of the parameters, the start of the delay of the block 10 signal comes from block 8. If the parameter does not correspond to any of the classes in the control process, block 10 will trigger and its signal in block 1 will indicate that the object is not valid. The device will stop working. However, if the AI parameter corresponds to one of the gp classes, then it is advisable to monitor the subsequent parameters only in this class. This task is solved by the distributor 11, the memory block 12, the block of elements And .13 and the counter 14.

The choice of the class in which A, “suitable for subsequent Lg, ... A5 parameters is achieved by the fact that the distributor 11 in the first cycle connects the output of the trigger 7 to the inputs of block 12 and to the inputs of block 13, and in subsequent cycles only to the inputs of block 13. Therefore, the signal from the corresponding element of block 13 will be fed to the input "disruption of the delay of the block 10 lisch at. the coincidence of the number of the memory element of the block 12 with the distributor increment 11, at which the trigger 7 tripped. The block 10 will not trigger. Thus, if the parameters A1, ... Az will correspond to one of the m classes, then when each parameter is monitored, one of the coincidence elements of block 12 will receive an impulse "delay," triggering it from the delay unit 10. The same impulse will also flow into counter 14. Reaching a specified count after the AS control, counter 14 will give a signal to block 1, which indicates that the object is valid, class, gradation.

The task of accelerated passage of sections of all tolerance classes, with the exception of one, in which AI is valid, the second trigger 15, switch 16, forms a single pulse 17. and a pulse generator 18. At the end of the first cycle of operation, the distributor 11 will issue a signal to a single trigger input 15, the output potential of which will act as a signal "operation on switch 16, performed similarly to distributor 11, and generator 18, which will begin to output to unit 1 control of its operation higher-frequency pulses. In this case, the switch of unit 1 is carried out by viewing it; sections of tolerance classes. The switch 16, controlled by the pulses of the distributor 9, will begin to connect the outputs of the elements of block 12 to the former 17. When the switch 16 reads a high potential of one of the elements of block 12 to the input of the former 17, the latter will issue a strictly defined value pulse to the input of the generator 18. the existence of this pulse generator 18 does not work. At this time, the information of block 5 is being read at the input of element AND 6 and the subsequent normal operation of the entire apparatus. If this parameter corresponds to the class tolerance, then the delay block 10 does not work, and after the pulse pulse of the imaging unit 17 expires, the equipment will again work in an accelerated mode in the manner described above. Efficiency in improving the speed of the equipment depends on the type of switch used in unit 1.

The frequency of the generator 18 is selected depending on the type of switch used in block 1. So if this switch consists of stepping finders (IC), then the limit frequency of generator 18 is selected according to the limit frequency of the IC with the exception of the on-channel time for switching signals. The switch of unit 1 can be built on a relay with a group indication of switching on, or by the method of a contact pyramid. Multiple coordinate connectors (MKS) can also be used as a switch, forming switching channels of which are 5 s from a software device (PU). The number of the switching channel is determined by the state of a certain set, in the first case, the energized relays, in the second case, the energized and energized relays, or by switching on a certain used element of the ISS

0 by the method of two coordinates. The limit frequency of the generator 18 for such switches is selected from the condition of the maximum frequency of the control panel, but not from the condition of the operating and release times of the relay of the actuators of the ISS, the values of which are relatively large.

If the device uses an electronic switch of block 1, consisting of a circuit solution for generating a bipolar control voltage to open and

If the corresponding key Eotements are closed and the switching channel number is fixed by the counter, then the limit frequency of the generator 18 is selected in accordance with the limit frequency of the counter, and not the on time, on state, and off time. Thus, the use of the generator 18 when using various kinds of switches in the device provides a significant increase in the speed of the device.

Consider the operation of the device for two

options.

Let the object correspond to the second class. Then, when controlling the second class5 tolerance of the parameters AI "1 trigger 7, it is recorded in the second right memory element of block 12. As a result, from the last control outputs, the second input of the corresponding second right element I of block 13 and the input of block 1 will be fed high potential.
