Description

The invention relates to the field of measurement and control of the technical condition of complex technical systems and their elements, and specifically to a method for remote monitoring of the technical condition of military radio equipment (RTS).

Known methods for monitoring the technical condition of objects of technology (RU 2313815, SIEMENS AKTSIENGEZELLSHAFT, 12/27/2007, US 8014880, Fisher-Rosemount Systems Inc., 09/06/2011, RU 2649542, AO "POTEK", 04/03/2018.).

Closest to the invention by purpose and technical essence is a method for remote monitoring of the technical condition of objects of technology / RU 2649542 /.

A known method for remote monitoring of the technical condition of objects of technology (OT) / RU 2649542 / is as follows.

Directly at a remote object of equipment (FEP), remote from a service center for technical maintenance (CTP) of FEP, measure the current parameters (TP) of FEP, form the performance indicators (RCC) of FEP as a function of time t, and predict the exit time (t ₀ ) RCC beyond the permissible limits and impossibility of further operation of FEP. The results of predicting the RCC of the FEP and the initial data of the FEP parameters via a digital radio link are transmitted to a service center for an additional analytical assessment of the forecasting results and a decision on maintenance (maintenance) of the FEP.

At the same time, in the process of measuring TP, the rate of change (STP) is recorded, by changing the numerical value of the STP, the rate of change of the SCR UOT from the TP is simulated by the MSET simulation method using a limited number of SCR. The formation of the criterion for the RCC to go beyond the acceptable limits of working capacity is carried out directly on the FEP by the method of "residual" RCC and TP. Prediction of the moment t _{0 of} inoperative UOT is determined by the output of the numerical value of the RCC beyond the limits of the formed criterion. Due to the lack of accuracy of the results of forecasting at FEP for a limited number of RCCs, the central technical centers present a lot of numerical values of RCC and TP, where they repeatedly analyze the results of forecasting.

The disadvantage of this method is the prototype / RU 2649542 / is the relatively low productivity of remote monitoring of the technical condition of objects of technology. The specified disadvantage / RU 2649542 / is associated with additional time costs:

- duplication of the RCC forecasting process, first at FEP and then at the TEC;

- to transfer data from FEP to the central heating center via the Internet, used as a digital radio communication line, with limited bandwidth.

These shortcomings limit the use of the known monitoring method for the maintenance of radio equipment (RTS) in the field of armaments, military and special equipment (IHE) of the types and branches of the Armed Forces of the Russian Federation on automated systems for controlling the operation and life cycle of the IHE.

The objective and technical result of the invention is to increase the efficiency of obtaining operational information on an automated system of information and logistics support (ASILP), the degree of its relevance and reliability, as well as reducing the impact of the "human factor" on the quality of operational information received by ASILP monitoring, technical operation and maintenance Rs.

Achieving the claimed technical result and solving the problem is provided by the fact that the method for remote monitoring of the technical condition of radio equipment includes diagnosing the technical condition of remote radio equipment, transmitting the diagnostic results via a digital communication radio line (RCS) to a central service center (DSC) for making a decision on service maintenance Rs.

According to the invention, the technical condition of the RTS is diagnosed using the automated functional monitoring and diagnostics system (ASFKD) integrated in the RTS, and a broadband radio link with increased bandwidth is used to transmit the diagnostic results. In the process of automated diagnostics, a block U of data on the technical condition of the RTS is formed, including a set of diagnostic parameters of the RTS, described by a dependence of the form:

U = U _J {H _i (t), t≥0},

H = H _i , {Q (t), M (t), t≥0},

Where:

U- diagnostic parameters of the RTS;

H - initial information about the state of the RTS;

t is the time point of the diagnosis;

Q (t) is the set of characteristics of the operating conditions;

M (t) is the set of characteristics of the state of the RTS.

Next, the data U is converted into data Y of the state parameters of the RTS of the form Y = Y _n {U _j (t), t≥0}, from the received data Y, a low-density parity check codegram (LDPC code) of the digital signals is generated, and a block check matrix is simultaneously generated a quasi-cyclic LDPC code, an LDPC matrix encodes a block of Y parameters, encoded Y values as digital messages about the technical state of the RTS for the DSC.

In the process of transmitting encoded messages about the results of diagnostics in the DCS, data is converted Y = Y _n {U _j (t), t≥0}.

Convertible data is converted into a broadband radio signal and emitted in the direction of the DSC, which receives a broadband radio signal with Y data. Next, the DSC using wireless broadband access equipment decodes the radio messages from the RTS and transmits them in decoded form to the DSC server and to the workstation (AWP) DSC operator. In the DSC, from the received digital messages Y, they form in graphical and / or tabular form a plan for the maintenance, repair or modernization of the RTS.

A monitoring system that implements the proposed method for remote monitoring of the technical condition of military-technical communications RTS contains serially connected ASFKD 2, a data collection and processing unit 3 included in the RTS 1, a system for formalizing operational information about the technical state of the RTS into a codogram, and its further transmission to ASILP monitoring technical operation and maintenance of RTS 4, interface conversion unit 5 and workstation 6 from the ASILP monitoring, technical spluatatsii and service RTS 7 service.

8 RTS 1 automated systems of functional control and diagnostics are built-in 2. They are centralized systems of automated collection, distribution and processing of information and cover the control of the equipment of the main systems of RTS 1. ASFKD 2 built in RTS 1 consist of hardware and software and provide:

- automated functional control of the readiness of the RTS for use according to generalized parameters with an indication of the technical condition at the workplace of the RTS operator;

- automated continuous monitoring of the technical condition and performance of the RTS with the automatic issuance of information to the operator’s workplace;

- an automated mode for diagnosing and troubleshooting in RTS equipment with a high depth of localization of the fault address;

- automated assessment of the technical condition of the RTS equipment.

Also, RTS 1 includes a data collection and processing unit 3, which processes the results of diagnostics of RTS received from ASFKD 2 via internal data transmission channels.

From the information collection and processing unit 3, the information enters the operational information formalization system on the technical state of the radio equipment in the codogram and its further transmission to the automated control and monitoring system of monitoring, technical operation and maintenance of the RTS 4.

It includes an encoding device 4.1 (a verification matrix generation module 4.1.1 and an encoding module 4.1.2) using an LDPC code, a modulator 4.2, a 4.3 codogram transmission system consisting of series-connected: RTS 4.3.1 network equipment, wireless broadband equipment access 4.3.2; which includes a converter 4.3.3 and masted high-frequency radio equipment 4.3.4 from which a digital signal is emitted by a transmitter 4.3.5 to a receiver 4.3.6 connected via converter 4.3.3 to the corresponding network equipment 4.3.7. For radio exchange, an RHS is used, which has increased bandwidth and noise immunity, which allows to increase the reliability of radio communications and the degree of protection of transmitted information.

The implementation of wireless broadband access 4.3.2 standard WiMAX, mast high-frequency radio equipment 4.3.4 - in the form of integrated antenna systems, and converters 4.3.3 - in the form of a multi-channel signal converter with a built-in power supply unit allows optimal integration of operational information about the current technical condition RTS in the proposed digital network based on the well-known element base of increased performance and reliability. This additionally provides an increase in the performance, reliability and feasibility of the integrated digital communication network for transmitting the results of the RTS 1 diagnostic to ASILP 7.

Next, the resulting codogram enters the demodulator 4.4, and then to the decoding device 4.5, where the code words are sequentially converted.

Then, in the ASILP of monitoring, technical operation and maintenance of RTS 7, from the conversion unit of the interface 5 via internal data transmission channels, information is sent to the automated workstation of the ASILP for monitoring, technical operation and maintenance of RTS 6 to display the received information to the relevant official and make a decision about the service RTS service.

The monitoring system for the proposed method works as follows:

According to the algorithm shown in FIG. 1 after turning on the RTS (step 1), remote from the DSC, the process of diagnosing them is carried out, which consists of individual steps. The first step is the collection and processing of information from the main RTS systems (step 2). In general, the amount of information depends on the operating conditions of the weapon model, operating modes, quality of documentation, as well as the necessary and sufficient “depth” of diagnosis:

H = H _i , {Q (t), M (t), t≥0},

Where:

t is the time point of the diagnosis;

Q (t) is the set of characteristics of the operating conditions;

M (t) is the set of characteristics of the state of the RTS.

The next step in obtaining the initial data for diagnosis is the formation of the diagnostic parameters of the RTS (step 3), which are generally described by the dependence of the form:

U = U _j {H _i (t), t≥0},

The dependence determines the choice of diagnostic parameters of the RTS and the relationship with the incoming information.

Diagnostic parameters are converted by the system into the corresponding parameters of the RTS state (step 4):

Y = Y _n {U _j (t), t≥0}

The set of Y parameters of the state of an armament sample determines its state with a certain accuracy. The state parameters of the RTS are formed as a result of the conversion of the diagnostic parameters by the system. The quality (accuracy) of determining the state parameters depends on the ability of the system to select diagnostic parameters, determine the characteristics of their change and their connection with the parameters of the RTS state, set the standard values of the diagnostic parameters, determine the diagnosis method, select and justify the appropriate methods, measuring tools, optimal procedure or algorithm diagnosing.

Thus, after turning on the RTS and conducting automated functional control of the technical condition, as well as if a malfunction or failure is detected during the diagnosis process described above, the information collection and processing unit 3 receives and processes the necessary operational information about the current technical condition of the RTS (step 5 ) from a system of automated functional control and diagnostics 2 via internal data transmission channels. Further, this information enters the system of formalization of operational information on the technical condition of radio equipment in the codogram and its further transmission to ASILP monitoring, technical operation and maintenance of radio equipment.

When formalizing information about the current technical state of the RTS, a coding program with error correction is used in the codogram (step 6), which has greater coding efficiency. Among these, a low density parity check code (LDPC code) is known as an error correction code having a high coding efficiency.

An encoding device 4.1 using the LDPC code in the verification matrix generation module 4.1.1 generates a block verification matrix of the quasi-cyclic LDPC code (step 7) and passes it to the encoding module 4.1.2, which in turn performs encoding processing on the input message, which is digital signal, using a check matrix to generate a code word (codogram), and provides it to the modulator 4.2. After modulation of the codogram (step 8), it enters the transmission system of the codogram 4.3.

To implement the further process of transmitting the codogram, additional installation of monitoring, technical operation and maintenance of radio equipment 7 of the wireless broadband access equipment 4.3.2, including the converter 4.3.3 and the mast high-frequency radio equipment 4.3.4 connected through the converter, is required on each RTS 1 and on the ASILP 4.3.3 with the corresponding network equipment 4.3.1 and 4.3.7. The use of individual broadband access means for radio transmission with increased bandwidth and noise immunity allows to increase the reliability of radio communications and the degree of protection of transmitted information.

The implementation of WiMAX standard wireless broadband access, mast high-frequency radio equipment - in the form of integrated antenna systems, and converters - in the form of a multi-channel signal converter with a built-in power supply unit makes it possible to optimally ensure the integration of operational information about the current technical state of the RTS in the proposed digital network on a known element base increased productivity and reliability. This additionally provides an increase in the productivity, reliability and feasibility of the integrated digital communication network for transmitting operational information about the current technical condition of the RTS to ASILP 7.

Next, the codogram is converted and transmitted (step 9) with the help of the converter 4.3.3 and the transmitter 4.3.5 of the broadband signal installed on the integrated antenna system, respectively.

The next step is the reception and conversion of the codogram (step 10) using the wireless equipment of broadband access 4.3.2, consisting of a receiver 4.3.6 and a converter 4.3.3.

Next, the resulting codeogram is sent to the automated monitoring and control system for monitoring, technical operation and maintenance of RTS 7, where in the demodulator 4.4, and then in the decoding device 4.5, the codewords are sequentially converted: demodulation (step 11) and decoding of the resulting codeogram (step 12). After the conversion of the interface (step 13), operational information about the current technical condition of the RTS is transmitted via internal data transmission channels through the ASILP 5 interface conversion unit.

Then, the obtained operational information on the current technical condition of the RTS is output to the automated workstation of the automated monitoring and control system for monitoring, technical operation and maintenance of RTS 6 (step 14), for presentation to the appropriate official for decision-making (step 15).

The implementation of this invention will contribute to the solution ASILP monitoring, technical operation and maintenance of RTS the following tasks:

- remote monitoring of the technical condition of the RTS;

- increasing the efficiency of the implementation of RTS service activities;

- prediction of the technical condition of the VVST samples in order to determine the volume and terms of the necessary work for their maintenance and repair for a certain period of operation;

- planning work on maintenance and repair of RTS, including with the involvement of industrial enterprises, repair enterprises and service centers;

- preparation of reports and reports on the technical state of armaments and military equipment, preparation of reporting documents for technical operation and maintenance of RTS;

- keeping records of availability, consumption, forecasting needs, adjusting the composition of spare tools and accessories (spare parts) to the RTS according to the results of operation, generating applications for replenishing sets of spare parts.

This invention improves the efficiency of obtaining operational information on ASILP, the degree of its relevance and reliability, as well as reduce the impact of the "human factor" on the quality of operational information received ASILP monitoring, technical operation and maintenance of RTS.

The proposed technical solutions are new because the proposed method for remote monitoring of the technical condition of radio equipment, including diagnostics of the technical condition of remote RTS, transmission of diagnostic results from automated systems of functional monitoring and diagnostics of RTS through high-bandwidth RCS to ASILP monitoring, technical operation, is not known from publicly available information. and servicing the RTS to make a decision on servicing the RTS.

The proposed technical solutions have an inventive step, since it does not explicitly follow from the published scientific data and the known technical solutions that the claimed sequence of operations of the method leads to the expansion of the functionality of ASILP monitoring, technical operation and maintenance of RTS.

The proposed technical solutions are industrially applicable, as they are based on the well-known achievements of electronic and communication technology.
