The invention relates to automation,

and computer technology and can be used in the systems of built-in control of technical devices for finding the fault location among the elements covered by the feedback circuit.

The purpose of the invention is to increase the reliability of the control.

The drawing shows a structural electrical circuit of the device.

The device contains functional elements 1-5 of the control object, sensors 6 - 10 tolerance control, block

11 buffer registers, decoder 12, j pa of all functional elements.

block 13. registration of numbers of failed elements, 14 elements of the control unit, unit 15 of control time, setpoint 16 of the current time, keys 17, block 18 of registration of time of failure, shaper 19 of the read signal, object 20 of control.

In the initial state, when the parameters of the functional elements 1-5 of the object 20 are in the trigger field, there are no signals at the outputs of the sensors 6-10, the key 17 is closed, the registration unit of the numbers of the failed elements and the registration block for the failure burden are zero.

The device works as follows.

If one of the functional elements of the object 20 fails, the output corresponding to the two failed elements of the tolerance control sensor is a signal that enters the block 14 of the SHS elements and the block 11 of the buffer registers in which the number of the failed element is recorded. The output signal of the block 14 of the elements OR includes the monitoring device 15, opens the key 17, and the read signal generator 19 enters into operation. The signal about the current time value from the master 16 through the public key 17 enters the block 19, where the current time of the failed element is recorded. The former 19 controls the buffer register block 11, from which binary information about the number of the failed element is transferred to the decoder 12, where the conversion occurs.

the parameters of which left the tolerance field for the time set by parameter 15, and in block 18 for registering the time of the failed elements, the corresponding time for the parameters of the corresponding functional elements from the field was recorded.

The device is reset to its initial state after bringing the output parameters of the functional elements of the control object 20 to the limits of the pulse tolerance field Reset to the control time setter 15, the block 13 for registering numbers of failed elements and. block 18 registration time of failure.

The device allows one to fix the first monitored parameter out of tolerance and to block subsequent failure states of functional elements caused by a response to a true failure after the time set by the time delay block.
