Description

The invention relates to radar and can be used for the diagnosis and repair of integrated modules (IM) of radar stations (radar) in operating conditions.

The use in radars of antennas with active phased array antennas (PAR) sharply aggravated the issue of repair of integrated modules, especially receiving and transmitting modules, which in one radar contain from several tens to thousands of pieces. The failure of several HEADLIGHTS does not lead to the failure of the radar, but with the accumulation of faulty modules after some time, the question of their repair arises sharply. If this problem is considered on a national scale, there may not be a problem - they can be repaired at the factory. But for the vast territories of Russia and when operating similar radars in foreign countries, such an approach to repairing electronic components is economically disadvantageous to consumers.

The existing repair tools used in operating conditions are the universal repair module Moment (designer and manufacturer of the Nizhny Novgorod Research Institute of Radio Engineering, RF patent No. 54185), the mobile repair shop Vodichka (developer of VNIIPA in Moscow, manufacturer Kimovsky Plant “ Meteopribor ”), the maintenance module MTO-36D6 (developer and manufacturer of KEMZ Iskra, Zaporozhye, Ukraine) - provide for the possibility of repairing only electronic modules made on printed circuit boards.

Technical characteristics of the closest analog products “Moment” and “Vodichka” are given in the “Arms of Russia” catalog for 1996-1997, part 11.

Diagnostics, repair and verification of sealed gas-filled integrated modules listed above repair tools do not provide. They do not include technological equipment for opening, closing and filling with inert gas the sealed enclosures of integrated modules, as well as equipment for checking their electrical parameters.

At present, there are no means of repairing MI under operating conditions for a number of technical reasons related to the specific requirements for the technical process of repair and storage of spare parts for repairs. Repair of them is carried out only in the conditions of serial manufacturers.

Repair of electronic modules in existing repair tools is carried out as they become available in the order of priority, unless another procedure for conducting work is specified. With an increase in the flow of faulty modules above the performance of the repair tool, electronic modules are waiting for their order in the drive. Spare parts for repair of electronic modules in the specified analog products are case-based; they do not require special storage conditions; they are removed from spare property and accessories (spare parts) as necessary.

Spare elements for the repair of gas-filled IM require special storage conditions - sealed packaging with a limited shelf life of the elements after opening. Separate types of unpacked elements from suppliers come only in large batches of 500-1000 pieces in one sealed package, which is redundant for repairing MI. In addition, for repair, it is necessary to use separate units made with the use of housing-free elements, which require, in addition to protection from climatic influences, and protection from mechanical influences during transportation and storage.

Along with sophisticated technological equipment and the repair process, the above-mentioned problems of completing and storing spare parts and accessories with housing elements are an obstacle to the organization of repair of MI in operating conditions.

To overcome the existing obstacles for repairing MI in operating conditions, a method for batch repair of MI and a device for its implementation using specially designed and packaged group sets of spare property and accessories for a package of the same type of MI (ZIP-GIM) is proposed.

ZIP-GIM for IM repair is formed similarly to the group spare property and accessories (ZIP-G) for the radar group, taking into account the reliability of its components, individual elements that can be replaced when the module is repaired in the conditions of the proposed autonomous mobile repair site (AMRU). The number of modules for which one set of spare parts is supplied is calculated on the basis of their number in a single spare property and accessories (spare parts) of the radar, the duration of repairs and other requirements.

Features of the organization of the process of diagnosis and repair of MI at AMRU are that:

- faulty modules from the radar operating sites go to the AMRU, where they accumulate to the amount that the ZIP-GIM is designed for;

- when this amount is reached, the AMRU will organize batch repairs of this type of modules, for example, according to the algorithm of the technical process for diagnosing and repairing the IM shown in Fig. 1. First, they are checked for compliance with electrical parameters and tightness requirements. In the event of a mismatch, they are opened by MI, troubleshooting, repairing installation defects, replacing faulty elements with spare parts from spare parts, checking electrical parameters, sealing and filling with inert gas.

Considering that ZIP-GIM can be stored for a long time only in airtight packaging, all its elements after manufacturing (units) and individual parts taken from the factory sealed packaging at the module manufacturing plant must be fastened and sealed in a special container for long-term storage of spare parts GIM.

When repairing a package of modules, the remaining 1-2 modules, in case of a shortage of spare parts, are stored until the next full batch is formed in the conditions of a dried closed volume or in a sealed form.

When repairing the next package, the remaining modules from the previous package should be restored first.

After repair, the modules are issued in the established order to operating organizations.

If it is impossible to eliminate the malfunction under AMRU conditions, the module in a sealed form is sent to the manufacturer or written off in the established order.

The proposed method of batch repair of gas-filled integrated modules can practically be implemented using the proposed AMRU, which includes a set of technological, diagnostic, auxiliary equipment and spare parts-SIMs and placed in a specially equipped transported container.

The technical result of the proposed method and device is the ability to diagnose and repair integrated radar modules in the conditions of their operation, including field ones, as well as reducing the volume and cost of spare parts and accessories for radars by reducing the number of radar.

The proposed device, presented in figure 2, consists of rooms in which there are three workplaces (RM) for performing all operations for repairing MI (RM-1, RM-2 and RM-3), and auxiliary rooms.

RM-1 is intended for accumulating faulty IMs, sealing and checking their tightness, pumping air, filling them with inert gas, tinting (repainting) and drying.

The composition of RM-1 includes:

1 - cabinet with hood for tinting and drying the modules;

2 - equipment for pumping air from the modules and filling them with inert gas;

3 - equipment for sealing and checking the tightness of the modules;

4 - a closable cabinet for storage (accumulation) of modules received for repair and repair.

At RM-1, records of accepted and repaired MIs are kept.

RM-2 is designed for opening and closing modules, replacing components and individual electrical radio products (ERI).

The composition of RM-2 includes:

5 - device for preheating modules;

6 - soldering installation with a microscope;

7 - small-sized installation for laser welding of elements;

8 - ZIP-GIM of various types of modules, consumables, devices and a cabinet for their storage

RM-3 is intended for monitoring and diagnosing module malfunctions, for carrying out adjustment work.

The composition of the RM-3 includes:

9 - PC with databases on all issues of repair and diagnostics of modules, software for an automated control stand;

10 - an automated MI control stand that provides MI with control signals and controls the MI response to these signals;

11 - universal power supply modules;

12 - a rack with instrumentation (instrumentation), autonomous stands, cables and technological transitional devices.

Each workplace has in its composition a set of necessary tools and technological devices in accordance with the work performed.

Workplaces are separated from each other by transparent partitions with windows for the transfer of repaired modules and sliding doors for passage of personnel.

At the entrance to the working area of the container, a vestibule is equipped for storing outer clothing, shoes, work robes and replaceable shoes.

The compartments of the container for placing the MI diagnostic and repair device are equipped with air conditioning systems with cleaning, technological exhaust ventilation, air pumping and inert gas supply systems, autonomous automatic electric heating, a system for supplying voltage to workstations from an industrial network or own autonomous power source (AIP )

The power supply and life support systems for diagnostic and repair workstations are mounted in a separate compartment of the container, with the possibility of the AIP removal by 10-20 m from the container in order to reduce noise and vibration on the PM.

Thus, the proposed method of batch repair of gas-filled integrated radar modules with headlamps, based on the use of spare parts, and a device for its implementation, made in the form of an autonomous mobile repair site, provide the ability to repair these integrated modules in the radar operating conditions (remote areas, foreign countries, field conditions, etc.).
