The invention relates to measuring technique and can be used in the design, manufacture, testing and operation of electronic products (REI). The technical result is an extension of the class of solvable problems and improving the reliability of analysis results due to the introduction of control points of failures and their duration, pseudoparallel processing of monitored parameters.

There are devices designed to detect and failure analysis [1-3]. The main disadvantage of these devices is their inapplicability in modern conditions for the control of microprocessor technology, which, along with a failure occurs, a large number of failures [5]. All they are designed to control a single electronic products.

The device prototype contains a threshold unit, the pulse shaper, delay elements, elements, elements, OR, a differentiating element, triggers, inverters, generators pause, pulse counters, switch, case-sensitive.

The disadvantage of this device is that it captures only a gradual failures and does not take into account failures and is designed to control only one electronic products. If the monitored device recovers from a failure, the device is idle and cannot perform any functions. Therefore, the use of this device is difficult due to the fact that it must be manufactured for each REI. In addition, it cannot be used to control modern REI, which include computing, affected not only failures, but failures.

The principle of operation of the device is as follows. If you get a slice of the reference pulse corresponding to the maximum duration of the output parameter for the border area of health, for the period of stay option in the field of health carried out an analysis of the duration of this period and, if IU is the more, than the minimum task time, it is assumed that at the initial intersection of the boundary parameter fails. This refusal is recorded, and the duration of the considered reference pulse is included in the total duration of the failure. In addition, the decision about what option is returned in the field of health, adopted by the analyzer only after time after crossing the boundary parameter in the direction of the field of health will be equal to the minimum duration of the task. At this point, reset the driver of the reference pulse, and the device is prepared for the analysis of the new crossing boundaries. If the parameter was in the field of failure over a short period of time, the analyzer records the fact of occurrence and the duration of the failure. If the number of failures has reached the threshold value, the analyzer records the fact of failure.

The aim of the invention is the expansion of the class of tasks by improving the accuracy of the results of the analysis by introducing control failures and the introduction of simultaneous processing of control parameters several REI.

This objective is achieved in that in the device [1] introduced a control unit that contains the data selector pulse counter modulo N clock generator pulses, the delay elements of the block I is EEK memory the elements of And, OR and control unit failures that contains the frequency divider, pulse counters, myCitadel, element OR panel display (see drawing).

The analyzer works as follows.

The device consists of the following blocks: the control of gradual failures, control unit failures and control unit.

The principle of operation of the control unit of gradual failures described in [1]. It consists in the comparison time parameter in otkazivau region and the maximum time parameter in otkazivau area. If the time parameter in otkazivau region will exceed this threshold, it is identified as a failure and its duration. The total number of reported failures is stored in the counter 17, and the duration is recorded in the counter 22.

Describe the operation of the control unit containing the data selector 32 [4] (s), the third element OR 33, the clock 34 [4] (p. 24), the fifth counter 35, the second threshold block 36, the third inverter 37, the third delay element 38, the ninth element And 39, the fourth delay element 40, the fourth element OR 41, the pulse counter modulo N 42, the block of memory cells 43, scoreboard display 52.

The block of memory cells 43 is a matrix cell size N17. As a block of memory cells can be used storage device from the tyranny of the Noah sample [4] (s.255).

In cell [i, 1] contains the number equal to the absolute value ofwhere- the maximum time parameter in otkazivau area, above which is fixed failure of the control object;- the minimum required to complete the task, the time parameter in the field of health States, i is the number contained in the pulse counter 42. When switching the selector data from the i-th input to the i+1st in the cell [1, 2] records the number corresponding to the current value of the counter 26, in the register 24 and the counter 26 is recorded in the number of cells [i+1,1] and [i+1,2], respectively, in cell [i, 3] writes the contents of the counter 22, and the counter 22 is written the number of cells [i+1,3], cell [i, 4] is written, the contents of counter 31, and the counter 31 is written the number of cells [i+1,4], cell [i, 5] is written to the content of the counter 17, and the counter 17 is written the number of cells [i+1,5], cell [i, 6] recorded the contents of the counter 46, and the counter 46 is written the number of cells [i+1,6], cell [i, 7] writes the contents of the counter 47 and the counter 47 is written the number of cells [i+1,7], cell [i, 8] writes the contents of the counter 49 and the counter 49 record the number of cells [i+1,8], cell [i, 9] is written to the content of the counter 51 and the counter 51 zapisi what is the number of cells [i+1,9], in cell [i, 10] records the state of the trigger 9, and the state of the trigger 9 becomes equal to the value of cell [i+1,10], cell [i, 11] records the state of the trigger 15 and the state of the trigger 15 is equal to the value of cell [i+1,11], cell [i, 12] records the state of the trigger 16 and the state of the trigger 16 becomes equal to the value of cell [i+1,12], cell [i, 13] records the state of the trigger 27 and the state of the trigger 27 becomes equal to the value of cell [i+1,13], cell [i, 14] records the state of the trigger 29 and the state of the trigger 29 becomes equal to the value of cell [i+1,14]. The duration of a pause generated by the pause shaper 13 is stored in the cell [i, 15] and is equal tothe i-th subscriber.

Accordingly, when the switching of the selector data from the i-th input to the i+1-th value from the length of time generated by the pause shaper 13 becomes equal to the number of cells [i+1,15], corresponds tofor the i-th subscriber. When switching to the next caller, the duration of the pulse at the output of the driver 2 becomes equal to the number of cells [i+1,15]. In cell [i, 16] writes the contents of the counter 53 and the counter 53 is written the number of cells [1+1,16]. On the scoreboard display 52 displays the values of the memory cells with addresses [i, 5] (number of failures of a device connected to the i-th input) [1,3] (total length of alnost failure of the controlled device), [i, 9] (the number of failures of the controlled device), [i, 8] (total duration of failure), [i, 17] (mean time between failure for the desired period of time).

Clock 34 fills the pulse counter 35, which have a capacity K. the duration of the poll one device will be defined as T0=To-Ttwhere Ttthe repetition period of the clock pulses. The data selector 32 switches the input # 1 input of the analyzer. When filling of the counter 35 at its output pulse appears overflow, which, acting on the control input of the data selector 32, gives the command to switch to the next input. This same pulse passing through the fourth element OR 41, increases the number stored in the counter 42, per unit, which determines the number of the item that will be polled in this survey period, and the number of rows in the matrix of memory cells corresponding to this element. When the input of the counter 42 of the N-th pulse it is reset. The data selector 32 is switched to the input of No. 1.

If the output of the data selector 32 is present voltage, different from zero, the second threshold unit 36 generates a positive pulse which, inverters on the third inverter 37 and passing through the fourth delay element 40, prohibits the passage of the pulse through the ninth element And 39. If SelectedIndex 32 there is no voltage, the second threshold unit 36 generates a negative pulse, which, inverters on the third inverter 37 and passing through the fourth delay element 40, permit the passage of the pulse from the counter 35, the detainee to the delay element 40 through the ninth element And 39. This pulse passes through the OR element 41, increments the contents of the counter 42 and passing through the element OR 33, instructs the data selector 32 to switch to the next input. The time delay pulse delay elements 38 and 40, is equal to the time delay of the pulse counter 42.

Describe the operation of the control unit failures that contains a second frequency divider 44, the tenth element And 45, the sixth pulse counter 46, the seventh pulse counter 47, the first myCitadel 48 [4, n.218], the eighth pulse counter 49, the second myCitadel 50, the ninth pulse counter 51, the tenth pulse counter 53, the pulse shaper 55, the third frequency divider 56, the eleventh pulse counter 57, the fourth inverter 58, the eleventh element And 59, the twelfth pulse counter 60.

The pulse from the first threshold unit 1 is supplied to the second frequency divider 44, to the input of the tenth element And 45. The sixth pulse counter 46 will record the total duration parameter in otkazivau area. To input the first vicites 48 enters the number of the sixth MF is tcheka pulses 46 and the first pulse counter 22. In the eighth counter 49 will be recorded duration time of the crash. The seventh pulse counter 47 contains the number of all the facts of the output parameter in otkazivau region. From this value on the second myCitadel 50 subtracts the value contained in the second counter 17. The value of the output of the second vicites 50 is recorded in the ninth pulse counter 51 and corresponds to the number of occurred failures. Upon receipt of a positive pulse from the output of the ninth pulse counter 51, indicating that the counter is increased by one unit increases the value of the tenth pulse counter 53, the capacity of which corresponds to the threshold number of failures after which fixed the failure. Pulse overflow output of the tenth pulse counter 53, passing through the fifth element OR 54, increases the value of the counter 17, containing the total number of failures. The pulse shaper 55 generates a positive pulse at the input of the third differential element 56, which fills the eleventh pulse counter 57, the capacity of which determines the time required to determine the cycles to failure. Until the eleventh pulse counter 57 is filled, that is, its output will be a negative potential, the fourth inverter 58 permits the positive pulse from the output of the ninth accounts is Chica pulses 51, indicates that the counter value is increased by one unit through the eleventh element And 59, which fills the twelfth pulse counter 60. Overflow eleventh pulse counter 57 pulse overflow with its input is fed to the control input of the twelfth pulse counter 60, indicating that the value of the twelfth pulse counter 60 is intended to be written in the memory cell [i, 17], and it has to be reset. Thus, in the memory cell [i, 17] will have a value between failure for the desired time value.

On the scoreboard display for each device displays the following options:

- the number of gradual failures (the content of the counter 17);

- total duration of gradual failures (the contents of the counter 22);

- total duration of failures (the contents of the counter 49);

- number of failures (the contents of counter 51);

- mean time between failure (the contents of the cell [1,17]).

For further processing of the data options allow you to find a statistical evaluation of the reliability of the controlled object (mean time between failure, probability of failure-free operation, availability, and others).

Thus, by implementing simultaneous control N REI connected to the analyzer, the increased efficiency of the use of this device is relatively prototype N times and there is no need to disconnect the analyzer from one REI to control the other. Improved control accuracy due to the introduction of the fixation process failures REI and their duration. Based on these results, a decision that the health or unhealthy controlled REI. The control unit allows the survey of active devices running at the moment. If the device does not work, the analyzer does not control this device. Scoreboard display enables you to observe the change of monitored parameters for all connected devices simultaneously.

FIELD: automatic control, applicable in systems with excessive quality of transducers, for example, accelerometers, a failure of one of which should not result in a failure of the control system.

SUBSTANCE: the method is based on a periodic check-up of relation between the measured parameters of motion characterizing the correct operation of the transducers, fixation of the moment of failure of the relation, comparison of the readings of the transducers at this moment and at the moment preceding the moment of disturbance of the relation, and determination of the failed transducer by the results of the comparison.

EFFECT: expanded functional potentialities due to possibility of determination of the failed transducer in any excess system.
