Abstract

The invention relates to signaling and can be used in systems for automated control of objects, in particular in control systems for digital devices. The aim of the invention is to increase the information content of the device. The purpose of the invention is achieved by the fact that OR-NOT elements are entered into the device containing input 1, memory block 3, pulse distributor 4, encoder 5, display block 6, pulse generator 7, coincidence element 8, starting node 9 and control input 10 11 and a control unit 2 containing a counter, a trigger and descramblers, and a pulse distributor 4 is made controllable. When the device starts, the polling cycle begins. The arrival of a malfunction signal from the test object is stored in memory block 3. At the end of the polling cycle, a pulse generator 7 is started and a parallel code from memory block 3, a controlled valve distributor 4 pulses is converted into a serial one, which is fed to an encoder 5, which converts it into a binary one, which is displayed on the display unit of the display 6. When polling the display goes off, which indicates the survey, when the object is in good condition, the number 0 is displayed, if any circuits malfunction or the deviations of the parameters of the monitored object correspond to these chains or parameters. The device can operate cyclically indefinitely until the first failure of the monitored object. The mode is set by the signal applied to control input 10. 1 hp f-ly, 2 ill.

Description

The invention relates to signaling and can be used in systems for automated control of objects, in particular in control systems for digital devices.

The aim of the invention is to increase the informativity

FIG. a block diagram of the device is presented; Fig 2 - control unit.

The device comprises an input I of the device, a control unit 2, a memory block 3, a controlled pulse distributor 4, an encoder 5, a display unit 6, a pulse generator 7, a coincidence element 8, a starting node 9, a control input 10, and element 11 OR.

-Block 2 control contains counter 12, decoder 13, trigger 14 and decoders

The combined inputs of the installation in O of the counter 12 and the trigger 14 are the first (installation) input of the control unit 2, the output of the trigger 14 is the output of the mode of the control unit 2, the inputs of the decoders are the second input of the unit 2, and their outputs are the outputs of the control unit 2 of the control.

Memory block 3 can be executed on triggers, display block 6 in the form of a digital scoreboard

The starting node 9 contains the RSHI element and a button connected to the nepBotty input of the OR element, the second input of which is the input of the starting node 9, the output of the element PfflH - / its output.

The device works as follows.

When the button of the starting node 9 is pressed, its output signal returns to the initial state all the block triggers. 3 memory and trigger 14 block 2 control. The signal O from the output of the mode of the control unit 2 is fed to the enable inputs of the generator 7 pulses and the display unit 6, prohibiting their operation. The display of the display unit 6 is extinguished at the same time, thereby indicating the beginning of the polling cycle, the duration of which is set by the counter 12 and the decoder 13. When the counter input 12 arrives at the synchronous input, a certain number of clock pulses are connected to the input of the installer in 1 trigger 14 , a signal appears triggering switch 14 to the state

one . The signal 1 resolves the operation of the generator of 7 pulses, for example, with a frequency of 1 Hz and a display unit b. At the same time, during the polling cycle, the corresponding outputs of the control unit 2 may generate impulses, indicating a failure of any circuit or an unacceptable change of the param of the object being monitored. Failure signals are memorized by the corresponding triggers of memory block 3 at the outputs of which a code is generated that corresponds to a certain degree.

The encoder 5 converts the position code of the memory block 3, separated in time by the control unit, by distributing the 4 pulses to the binary code, which is fed to the display of the display block 6. Thus, on the digital display of the display unit 6, the period-j can be observed successively. . since the change of digits characterizing the degree of operability of the object under control. If there was not a single failure during the control cycle,

If it is necessary to monitor the state of the object for an indefinite period of time, the signal is fed to the control input. the end of the first cycle of control after pressing the button of the starter 9 in the absence of failures of the monitored object (triggers of memory block 3 remain in the initial state) on the display of display 6

In this case, the display of the display unit 6 again goes out, and so on. The monitoring process continues, with a cyclical highlight of the figure O (Loss of failures), until at least one failure of the monitored object occurs. At the same time, at the output of the element OR NOT 11, the signal O is formed, and the self-start of the device is terminated
