Description

The technical field to which the utility model relates.

The utility model relates to the field of monitoring and diagnosing electronic devices and can be used in monitoring and diagnosing electronic devices. State of the art

A device of an automated measuring instrument is known, in which the method of reference signals and reference devices is used, the structural diagram of which consists of a series-connected control computer, a common channel, a signal source, a reference device, and the second output of the signal source, outputs of the calibrated device, reference device, an analog-to-digital program-controlled converter (ADCU) and a computer are connected to the CPC, and the computer output is to a verification operator (see the book edited by Professor V. A. Ku netsova "Metrological maintenance and operation of the measuring equipment." Radio and Communication, Moscow, 1990, p.145, Fig.5.1.).

The disadvantage of this device is the lack of accuracy in measuring the values of the REA parameters and, as a result, errors in determining the technical condition. This disadvantage is due to the lack of a device between the computer system bus and the control object.

Closest to the claimed invention is a device, an automated control system of the parameters of the amplifier, consisting of a computer, printer, control object, buffering unit, optronic unit

decoupling, data control unit, address decoder block, digital analog converter block, control register block, input signal switch block, output signal switch block, current sensor block, analog-to-digital converter and adjustable voltage regulator block of the power supply. This device implements a method of monitoring the electrical parameters of the amplifier, which consists in the fact that the controlled physical quantity of the amplifier is first set up, a sequence of control signals and initial data are generated for verification, which are then amplified and converted from digital to analog form, and then the setpoint voltage and the specified the supply voltage, which is simultaneously supplied to the control object, takes the value of the controlled physical quantity in the form of an output signal of the amplifier, convert it from analog to digital form, after that the digital signal is processed to determine the actual value of the controlled electrical quantity and compare this value with the desired (see AC RF №2212674 C1).

The disadvantage of this device is that it does not allow predicting the technical condition of the control object, as a result of which, it cannot prevent failures occurring between the control measurements.

The diagnostic device for electronic equipment in the current state works as follows:

With a computer 1, which controls the operation of the device and implements the forecasting method algorithm, either the control step information is entered into the input unit of the control step 5 through the operator, which is then fed to the input of the control unit 6. The control unit 6 generates data collection signals at specified intervals from control points of the control object to 7 control units of parameters k.1 ... kn Information about the state of the monitored parameters from the outputs of the parameter control blocks k.1 ... kn is fed to the inputs of the analog-to-digital converter 8, in which information about the values of the measured parameters is converted into a digital code, which then goes to the corresponding inputs of the tolerance control block of parameters 9, in which the data obtained are compared with their nominal values and it is determined how far they are from the tolerance limits. From the outputs of the unit for tolerance control of parameters 9, this data in the form of a digital code is fed to the inputs of random access memory 10. The use of random access memory 10 allows you to receive and process several values of the monitored parameters in one clock cycle of the device. Information from the outputs of random access memory 10 is fed to the corresponding inputs of the decoder block of address 11, in which the code of the element is determined, the controlled parameter of which approaches the tolerance limit faster than others, or has already gone beyond it. After that, the address decoder unit 11 gives the enable signal to the data control unit 3 to generate a recording signal for the buffering unit 4. The buffering unit 4 generates and amplifies the sequence of data received by the optocoupler isolation unit 12, which provides galvanic isolation of the equipment under test from the computer system bus 1. The computer 1, receiving the control results in digital form, signals the operator by output

results on the display screen, on printer 2, or, if necessary, saves them as a file.

The proposed utility model allows you to:

- significantly reduce the failure rate, thereby increasing the reliability of the diagnosed equipment, due to the timely detection and prediction of the development of gradual failures;

- increase the coefficient of readiness of electronic equipment for use;

- reduce the time required for repair work.
