(54) DEVICE FOR MONITORING THE PARAMETERS OF FUNCTIONING OF COMPLEX TECHNICAL OBJECTS 12

This device has low functional capabilities and is not suitable for monitoring the parameters of technical objects to whose input test signals are inadmissible due to the possibility of an emergency situation. In addition, the local device has a low speed of detecting output parameters outside the normal range due to the absence of a dispatcher block that changes the control program depending on the changed situation during the execution of this control program.; In addition, the known device does not allow to estimate the direction and the actual value of the deviation of parameters from HopNuJ and does not register these values, which does not allow collecting operational information necessary for predicting the reliability of the performance of complex technical objects and their elements.

The aim of the invention is to increase the reliability of control and speed of the device.

The goal is achieved by introducing an evaluation unit, a standard driver and a control results analyzer into a known device, the inputs of the evaluation unit being connected to the outputs of the measurement unit and the standard driver, whose input is connected to the third output of the controlled switch, the fourth output of which is connected to the first: input of the registration unit, the second input of which is connected to one output of the evaluation unit, the other outputs of which are connected to the inputs of the display unit and the control results analyzer, the output of which It is connected to the input of the program block, and the output of the program block is connected to one of the control inputs of the serial switching unit.

The drawing shows a block diagram of the device.

The device contains sequentially connected program block 1, decoder 2 commands, synchronization block 3, operative data block 4, controlled switch 5, indication block 6, driver of 7 standards, measurement block 8, sequential switching unit 9, remote control 10 controls, control object 11, evaluation unit 12, control results analyzer 13, registration block 14, parameters sensors 15.

Measurement unit 8 serves for collecting and transforming information from sensors, for normalizing and averaging signals, filtering noise and spurious signals and consists of a set of typical amplifying and converting links that provide representation of various electrical quantities of monitored parameters at an appropriate scale of the DC voltage. The shaper 7 serves to formulate the standard of a normal situation, perform the function of entering settings of controlled parameters into an evaluation unit, performing a quantitative assessment of the deviation of monitored parameters from the norm, its magnitude, direction and speed, which allows to qualitatively determine the state of the object. Using logic control algorithms, it determines the number of the parameter of the apparatus, the node whose state is different from the norm, and

5 causes the deviation and sends a signal to the recording and indication units used to present and store the operational information for a long time.

0 Analyzer 13 is used to determine the priority of the control parameters and for the name of it, or the control program. The basis of his work is a model of causal relationships of a specific technological object or process, built by studying the causal logic of events.

Unit 1 is used to store control programs for individual parameters and their groups that characterize the components of a complex technical control object.

The device works as follows.

The controlled switch 5, according to the signal coming from the program 1 block through the decoder 2 and block 4, prepares the former 7 for the new control cycle, and through it the block 12 and the analyzer 13, as well as

0 measurement units 8, registration 14 and indication b. The test program of the test object 11 of the control is read by block 1 line by line with punched tape, with each line being generated — a synchronizing pulse arriving at the input of block 3, and commands entering the decoder address registers 2. The first line of the frame does not carry information, the first sync pulse corresponds to the state of block 3, in which at its output a reset signal is generated by the working memory of the operating registers of the switch 5. With the arrival of the second line frame, the command signals of the reference address are controlled by pairs tra fed to the input komlutatora 5 simultaneously with the arrival of synchronization pulse. The control switch 5 provides the selection of the corresponding

0 reference in the driver 7. At the same time, in the cocmutator 5, the Section for the selection of the measurement scheme and normalization in the block 8 is completed.

5 a. manual mode by the operator from the control panel 10 or in the automatic analyzer 13, block 9 connects sensors of parameters 15 located on the control object to block 8, where the conversion of monitored quantities is performed, their normalization, filtering of interferences, averaged using the wagged moving average algorithm. Separate parameters and group of signs are received in evaluation unit 12, where individual ghosts are compared with settings and the value and sign of deviation of this parameter from the tolerance limits are determined, and the groups of signs of monitored parameters are formed. The values of the main monitored parameters are: the recording and indication units 14, which also receive signals from the built-in sensors 15. In the recording unit 14, the causes and time of downtime of the main process are recorded equipment. If the parameter being tested is within the tolerance, the analyzer 13 generates a start signal from blocks 1 and 9 to continue the selected proM paMNW monitoring of the state of a complex technical object. If the parameter goes beyond the tolerance limits, the start-up pulse of blocks 1 and 9 is developed only after defining a new control sequence in the analyzer 13. After the complete control program has been completed, the operator’s console and the electrical panel of block 6 display and light up: generalized state characteristic complex technical object of control - Good condition, Healthy status of Avari, as well as the number of the failed node and the number of the parameter that has gone beyond the tolerance. At the same time, the seterator has the ability to actively influence the object (to set up, set up, repair and replace failed nodes, etc.) and then start block 1 of the program for calling control of parameters of failed nodes. Before performing a new polling cycle of the sensors 15 to the input of the device, a test test signal from block 1 of the program is supplied and the operation of the device in test mode is simulated. In case of non-conformity of the device response, the analyzer 13 generates a diagnostic device failure signal to the test signal and stops its operation or sends a signal to the serial connection of redundant units operating. in the cold reserve reokime, in the case of the presence of redundancy. All blocks constituting the proposed device can be implemented on the basis of known elements and nodes of digital-analog computers. Such a device building structure provides an increase in the speed and reliability of monitoring and diagnostics, and an increase in the accuracy of the quantitative, qualitative assessment of the performance of hearing technology objects.
