Description

The invention relates to automated measuring systems for monitoring and diagnosing complex electronic equipment.

The automated control and diagnostic system (ASKD) can be used both as part of existing and as part of modernized or newly created spatially distributed communication nodes (US) for various purposes for routine monitoring of the technical condition, diagnostic and repair work of electronic equipment (CEA) ) in the places of its operation.

A well-known automated monitoring and diagnostics complex is designed to create compact jobs for monitoring, diagnosing malfunctions and repairing interchangeable functional units of electronic equipment (patent RU 2257604). Through the use of the control computer and various programmable units (signal generators of a special form, signature and logic analyzers, an oscilloscope, power supplies, a synchronization unit, a generation unit and a unit for measuring high-frequency signal parameters) and a switch, stimulating effects are generated ( test signals) to the object of control, measurement and analysis of responses to them. At the same time, monitoring and diagnostics of digital, digital-analog, analog-digital and high-frequency REA circuits is provided. The disadvantage of this automated complex of monitoring and diagnostics is the impossibility of monitoring the technical condition and diagnosis of CEA in the process of its functioning. Another disadvantage of this complex is the need for delivery of REA functional units for monitoring, diagnostics and repair to the location of the automated complex, which ultimately leads to an increase in the total time of diagnostics and repair of REA due to delivery time.

Known automated control system (patent RU 2015622), based on the transmission of digital signals and converted to digital code analog signals from the object of control by fiber optic link for processing in a computer. The disadvantages of this system are:

limited automated control of only one object;

the impossibility of diagnosing faulty nodes as part of complex electronic equipment.

Also known is an automated system for monitoring the parameters of electronic circuits (patent RU 2106677), which allows you to set stimulating effects and control the parameters of electronic circuits of digital-analog, analog-to-digital, digital and analog REA nodes based on computer processing of the analyzed signals. The disadvantages of this system is the locality of its application and the possibility of simultaneous control of only one electronic circuit.

Other examples of CEA automated control systems with similar functionality and similar disadvantages can be found in patents RU 2150730, RU 2157559.

Close to the claimed invention is a repair and maintenance method and the hardware and software complex used for diagnostics and a system for monitoring the quality of repairs and maintenance (Application for invention RU 2007103326), although this method and system do not belong to the field of electronic monitoring and diagnostics devices. The disadvantage of this method and system is the inability to control the technical condition of objects in the process of their functioning, as well as the fact that individual functional units of a complex technical product act as objects of control.

The technical result from the use of the invention is:

the implementation of automated control of electrical parameters characterizing the technical state of CEA and the detection of REA faults in real time;

implementation of automated remote control of CEA in remote, including unattended, hardware spatially distributed CSS during diagnostic and repair work, as well as in the operation of CEA;

providing diagnostics of replaceable faulty blocks and REA units in depth to a failed electrical radio element.

The specified technical result is achieved in that the ASKD REA, which includes the automated measuring complex (AIC) of the USB manager, a switch (router), local AICs and adapters located in the hardware of the USB, are connected to an Ethernet network, characterized in that the controller’s AIC performs the functions of a server in Ethernet network, each local AIC in the network is a client and has its own unique address, the outputs / inputs of each CEA sample, which has its own identification tag and a list of monitored parameters, are connected to the input channels in the control room equipment / output of the corresponding local AIC (using adapters if necessary), which performs sessions of measuring electrical parameters of CEA, monitoring the compliance of these parameters with normalized values, creating and maintaining a database (DB) of measurement results, exchange of measurement data between the local AIC and the AIC of the dispatcher over the network Ethernet

A hardware DC is a set of radio electronic equipment located in one or several combined rooms of an electronic equipment.

Various signal converters, adapters, and other devices act as adapters in the hardware US, ensuring the matching of input / output channels of local AICs with the technological, control, and information outputs / inputs of REA (monitoring objects) by types of interfaces and connectors.

Figure 1 shows a variant of ASKD CEA spatially distributed CSS.

This option of ASKD REA contains AIC of dispatcher 2, located in the dispatching office of a spatially distributed USB 1, switch (router) 3, cable or fiber-optic Ethernet Ethernet 4, local AIC 5, located in hardware SS, where n is the number of hardware, i = 1, 2, ..., n - i-th hardware room, adapters 6, through which REA-objects of monitoring and diagnostics 7 are connected, a documentation device (printer) 8.

In ASKD REA organized distributed database technology "client - server." In the AIC of Manager 2, a database (DB) is organized for the entire CEA, structured into groups in accordance with the location of the CEA in each of the n hardware DCs, identification features, controlled electrical parameters, regulatory tolerances of electrical parameters and measurement results of parameters for each CEA sample and representing a server part of a distributed database. In the local AIC 5, a database is organized across the entire REA located in the i-th hardware facility, structured by identification features, controlled by electrical parameters and regulatory tolerances of electrical parameters and measurement results, and is a client part of a distributed database.

ASKD REA can work in two states:

control of technical condition;

diagnostics of the technical condition.

A measurement session in the state of REA control (unit, unit) is understood as the procedure for measuring current electrical parameters at the output of REA (unit, unit) in the process of their operation.

A measurement session in the diagnostic state of the REA technical condition is understood as the procedure of generating one or a set of test signals, applying a test signal to the REA input (block or unit) and receiving a response to it from the output of the REA (unit, unit).

ASKD REA can work in three modes:

local manual control and diagnostics;

local automated monitoring and diagnostics;

remote automated control and diagnostics.

The mode of local manual control and diagnostics provides for conducting measurement sessions with the direct participation of the operator. In this mode, ASKD REA works as follows (using an example of a single hardware CSS).

To conduct measurement sessions in the local AIC 5, the REA state type is set - control or diagnostics.

In the state of CEA control by identification signs from the database of the local AIC 5, a CEA sample is set and electrical parameters that are to be measured are selected. In the control program of the local AIC 5, virtual measuring instruments are used to measure the selected electrical parameters.

At the command of the control program of the local AIC 5, a measurement session is started. From the outputs of the controlled sample of CEA (block, unit) 7 to the corresponding inputs of AIC 5 (if necessary, through adapters 6), electrical signals are received, the current parameters of which are measured by appropriate virtual measuring devices. The results of the parameter measurement session are recorded in the database of the local AIC 5, in which the value of the system time is assigned to the conducted measurement session. In the database of the local AIK 5, the measured values of the parameters of the signals from the REA outputs are compared with the regulatory tolerances of the electrical parameters. If the values of the measured parameters of the signals do not go beyond the regulatory tolerances, a logical decision is made about the working condition of the sample CEA (unit, unit) 7, otherwise - about the faulty technical condition.

In the state of diagnosis of CEA by identification signs from the database of the local AIC 5, a sample of CEA is set and the electrical parameters that are to be measured are selected. In the control program of the local AIC 5, virtual measuring instruments are used to measure the selected electrical parameters. In the database of the local AIC 5, test signals are set programmatically.

At the command of the control program of the local AIC 5, a measurement session is started. Test signals according to the commands of the AIK 5 controller are fed through its outputs to the corresponding inputs (if necessary, using adapters 6) of the diagnosed CEA sample (unit, unit) 7. From the outputs of the controlled CEA sample (unit, unit) 7 to the corresponding inputs of AIC 5 ( if necessary, through adapters 6) the responses of test signals are received, the parameters of which are measured by the corresponding virtual measuring instruments. The results of the test signal response measurement session are recorded in the database of the local AIC 5, in which the system time is assigned to the conducted measurement session. In the database of the local AIC 5, the measured values of the response parameters of the test signals from the REA outputs are compared with the regulatory tolerances of the electrical parameters. If the values of the measured parameters of the signals do not go beyond the regulatory tolerances, a logical decision is made about the working condition of the sample CEA (unit, unit) 7, otherwise - about the faulty technical condition.

In the mode of local automated monitoring and diagnostics ASKD REA works as follows.

To conduct measurement sessions in the local AIC 5, the REA state type is set - control or diagnostics.

In the REA control state, in the database of the local AIK 5, for identifying signs, the controlled REA 7 samples are set and the electrical parameters of each of the REA samples to be measured are selected. The control sequence of the given CEA samples, the sequence and frequency of the measurement sessions of the selected electrical parameters, as well as the virtual measuring devices used are set in the control program of the local AIC 5. From the outputs of the controlled CEA samples (blocks, nodes) 7 to the corresponding inputs of the AIC 5 (if necessary, through adapters 6) electrical signals are received, the current parameters of which are automatically measured by the corresponding virtual measuring devices. The results of each measurement session are recorded in the database of the local AIC 5, in which each measurement session is assigned the value of the system time. In the database of the local AIC 5, the values of the measured parameters of the signals from the REA outputs are compared with the regulatory tolerances of the electrical parameters. If the values of the measured parameters of the signals do not go beyond the regulatory tolerances, a logical decision is made about the working condition of the REA (unit, unit) 7, otherwise - about the faulty technical condition.

In the diagnostic state, in the database of the local AIK 5, identifiable CEA 7 samples are set by identification signs, and the electrical parameters of each of the CEA samples that are to be measured are selected from the database. In the control program of the local AIC 5, virtual measuring instruments are used to measure the selected electrical parameters. In the local AIC 5, for the selected controlled electrical parameters from the database, test signals, sequence and frequency are programmatically set, which, according to the commands of the AIC controller, are fed through its outputs to the corresponding inputs (if necessary, using adapters 6) of the controlled REA samples (blocks, nodes) 7. From the outputs of controlled samples of CEA (blocks, nodes) 7, the corresponding inputs of AIC 5 receive responses to test signals, the parameters of which are automatically measured by appropriate virtual measurements with instruments. The results of each measurement session are recorded in the database of the local agro-industrial complex, in which each measurement session is assigned the value of the system time. In the database of the local AIC 5, the values of the measured response parameters of the test signals are compared with the regulatory tolerances of the electrical parameters. If the values of the measured parameters of the responses of the test signals do not go beyond the regulatory tolerances, a logical decision is made about the working condition of the REA (unit, unit), otherwise - about the faulty technical condition.

For a visual representation, the current results of measurements of the REA 7 parameters are displayed on the monitor of the local AIC 5 in the form of a mnemonic diagram of each REA-object for monitoring and diagnostics, the color gamut of which is set depending on the logical decision made.

For both states - monitoring or diagnostics of CEA - the local AIC 5, at the request of the control program of the AIC of manager 2, transmits the results of each measurement session via Ethernet 4 from the client (local) database to the server database of the AIC of manager 2.

Remote automated monitoring and diagnostics mode provides for monitoring and diagnostics of electronic equipment operating in maintenance-free mode or in maintenance-free hardware control rooms, as well as in the temporary absence of maintenance personnel in hardware control rooms. In this mode, ASKD REA works as follows.

In the AIC database of dispatcher 2, a local AIC 5 is assigned, with the help of which the REA is monitored and diagnosed in the 1st hardware control room. By the command of the control program of the AIC controller of dispatcher 2, which, in accordance with the unique address of the local AIC 5, is transmitted through the switch (router) 3 via Ethernet 4, the assigned local AIC 5 is transferred to the remote monitoring and diagnostics mode.

In the control state, in the AIC database of dispatcher 2 for a specific local AIC 5, identifiable characteristics of the CEA 7 are set in the i-th hardware US and the electrical parameters for each given CEA 7 sample are selected, which are to be measured. According to the commands of the control program of the AIC of dispatcher 2, for the controlled electrical parameters in the local AIC 5, virtual measuring devices are selected and their operating modes are set (measured parameter, measurement scale, etc.). The control sequence of the given samples of CEA 7, the sequence and frequency of the sessions of measuring electrical parameters using the local AIC 5 are set in the control program of the AIC of dispatcher 2.

From the outputs of controlled samples of CEA (blocks, nodes) 7 to the corresponding inputs of AIC 5 (if necessary, through adapters 6), electrical signals are received, the current parameters of which are automatically measured by the corresponding virtual measuring devices. The results of each parameter measurement session are recorded in the database of the local AIC 5 and simultaneously transmitted via Ethernet 4 to the server AIC database of dispatcher 2, in which each measurement session is assigned a system time value.

In the AIC DB of the dispatcher 2, the values of the measured parameters of the signals from the outputs of the REA (block, unit) 7 in the i-th control room are compared with the regulatory tolerances of the electrical parameters. If the values of the measured parameters of the signals do not go beyond the regulatory tolerances, a logical decision is made about the working condition of the REA (unit, unit) 7, otherwise - about the faulty technical condition.

In the diagnostic state, in the AIC database of dispatcher 2 for a specific local AIC 5, the diagnosed CEA 7 samples are set by identification signs in the i-th hardware unit and the electrical parameters of each of the CEA 7 samples to be measured are selected. By the commands of the control program of the AIK of dispatcher 2, for virtual electrical parameters in the local AIC 5, the virtual measuring instruments are selected and their operation modes are set, and test signals are programmed from the database of the local AIK 5 for the given diagnosed samples of REA 7, which are given by the commands of the controller of the local AIK 5 through its outputs to the corresponding inputs (if necessary, using adapters 6) of controlled samples of CEA (blocks, nodes) 7. From the outputs of controlled samples of CEA (blocks, nodes) 7 the corresponding inputs of the local AIC 5 receive responses to test signals, the parameters of which are automatically measured by the corresponding virtual measuring devices.

The results of each measurement session, the responses to the test signals are recorded in the database of the local AIC 5 and simultaneously transmitted over the Ethernet 4 network to the server database of the AIC of manager 2, in which each measurement session is assigned a system time value.

In the AIC DB of the dispatcher 2, the values of the measured parameters of the responses of the test signals from the outputs of the REA (block, unit) 7 in the i-th control room are compared with the regulatory tolerances of the electrical parameters. If the values of the measured parameters of the signals do not go beyond the regulatory tolerances, a logical decision is made about the working condition of the REA (unit, unit) 7, otherwise - about the faulty technical condition.

For a visual representation, the current results of the measurement session of the REA 7 parameters are displayed on the monitor of the AIC of dispatcher 2 in the form of a mimic diagram of each REA-object for monitoring and diagnostics, the color scheme of which is set depending on the logical decision made.

In all operating modes of the ASKD REA, in the AIK DB of the dispatcher 2 and in the database of the local AIK 5, protocols for measuring electrical parameters are automatically generated that display the results of monitoring and diagnostics of any REA sample. The measurement protocol contains the following data:

CEA identification signs (for example, CEA name, serial number, conditional number, etc.);

system time of the measurement session (date, time);

names and values of the measured electrical parameters;

limits of regulatory tolerances of the measured electrical parameters;

logical decision made (good / faulty, normal / abnormal).

In the modes of local automated and local manual control and diagnostics, the measurement protocols generated in the database at the request of the operator can be printed on a documenting device (printer) 8 connected to the local AIC 5, and in the remote automated control and diagnostics mode on a documenting device (printer) 8, connected to the AIC of the dispatcher 2 (Fig. 1).
