Description

The utility model relates to computing and instrumentation and can be used to test performance, trouble shooting, repair of blocks, modules, cells of weapons and military equipment.

Several prototypes of a device for checking blocks and modules are known:

- An automated system for diagnosing digital devices, which is designed to test the health and search for faulty elements of digital devices. The automated system contains a personal computer, a pairing device, a contacting device, and a diagnostic object (RF patent for the invention 2097827, IPC G06F 11/00 (1995.01), G01R 31/28 (1995.01), published on November 27, 1997);

An automated system for diagnosing digital devices, which is designed to test the health and search for both faulty digital devices and analog ones. The automated system contains the following main components: a personal computer, an interface device, a contacting device, and a diagnostic object (RF patent for utility model 70720, IPC G06F 11/00 (2006.01), G01R 31/28 (2006.01), published on 02/10/2008).

The closest analogue of the claimed utility model is the “Automated Diagnostic System for Digital Devices”, which consists of three main blocks: a central module, a pairing device, and a diagnostic object. The central module includes a PC. The interface device provides the formation and control of input and output signals, which can be either analog or digital signals. The interface device through the contacting device provides communication of the Central module with the object of diagnosis. The control devices and the interface module form a central interface controller that exchanges information between the central module and the diagnostic object (RF patent for the invention 2430406, IPC G06F 11/00 (2006.01), G01R 31/00 (2006.01), published on September 27, 2011).

The problem to which the claimed technical solution is directed is to create a device for checking blocks and modules, which ensures operability testing, troubleshooting, repair of blocks, modules, cells of weapons and military equipment.

This task is achieved due to the fact that the test bench for blocks and modules of weapons and military equipment (SPBM IViVT) includes a personal computer (PC), a block for generating a time diagram (BFWR), a block for matching signal levels (BSUS), a contact device (CC) and the object of diagnosis (OD).

The technical result provided by the given set of features is the creation of a test bench for blocks and modules, which allows performing a functional check, troubleshooting, repair of blocks, modules, cells of weapons and military equipment.

The essence of the utility model is illustrated by a drawing (Fig. 1), which shows a block diagram of a test bench for blocks and modules of weapons and military equipment (SPBM IViVT).

The test bench for the blocks and modules of weapons and military equipment (SPBM IViVT) includes a personal computer (PC) 1, a time diagram generating unit (BFWR) 2, a signal level matching unit (BSUS) 3, a contacting device (UK) 4 and a diagnostic object ( ML) 5.

A personal computer (PC) 1 is connected to a time diagram generating unit (BFWR) 2 and is intended to control the process of diagnosing blocks and modules of weapons and military equipment.

The PC is equipped with a software package developed by the applicant organization. The composition of the software package:

- The main control and diagnostic module;

- data exchange module with BFVRD via USB;

- module for monitoring and diagnostics;

- module for generating a time chart;

- signature analysis module;

- editor of test programs;

- a module of ready-made programs for monitoring certain blocks, modules, cells;

- a module of typical test programs (RAM, ROM, etc.).

The block for generating a time diagram (BFWRD) 2 is connected to a personal computer (PC) 1, as well as through a contacting device (UK) 4 with a diagnostic object (OD) 5 directly or through a signal level matching unit (BSUS) 3 and performs the following functions:

- ensuring the exchange of information with the software package on a PC via USB;

- formation or broadcasting from a PC of the status of digital and analog outputs;

- reception, processing or transfer to the PC of the status of digital and analog inputs;

- general management and synchronization of the hardware complex via the CAN interface.

The signal level matching unit (BSUS) 3 is connected to the block for generating a time diagram (BFVR) 2 and through the contacting device (UK) 4 with the object of diagnosis (OD) 5. BSUS 3 is connected between the BFVRD 2 and through the contacting device (UK) 4 with the object Diagnostics (OD) 5 for matching signal levels if the unit requires signals with a level of + 10V, + 15V, -15V, as well as lines with high load capacity for operation of optocouplers. BSUS 3 provides the tested unit with power supply with levels of + 10V, + 15V, -15V.

The contacting device (CC) 4 with the object of diagnosis (OD) 5 is connected to the block forming the time diagram (BFWR) 2 directly or through the block matching the signal levels (BSUS) 3.

The claimed device has a combination of essential features not known from the prior art for devices of this purpose, which allows us to conclude that the criterion of "Novelty" for the utility model.

The device operates as follows.

Diagnostic object (OD) 5 is connected to a contacting device (CC) 4, which provides electrical communication between OD 5 and the block for generating a time diagram (BFVRD) 2. To coordinate signal levels if the block requires signals with a level of + 10V, + 15V, -15V, as well as lines with a high load capacity for operation of optocouplers, the UK 4 with OD 5 is connected to the BFRD 2 via BSUS 3.

The device can operate in several modes: - A mode for generating the status of outputs on PC 1 in real time, in which a time diagram is generated in the software and each change in the status of outputs is transmitted from PC 1 to BFRD 2, then it is installed at the outputs of BFVRD 2. After setting the state outputs reads the status of inputs BFWRD 2 and transferred to the software on PC 1.

- The mode of formation of the state of the outputs and the processing of the state of the inputs directly into the BFWRD 2 (stand-alone mode) with the possibility of transmitting intermediate processing results to PC 1. The algorithm for generating the status of the outputs (time diagram) and processing the status of the inputs is created and edited in the software, then it is written in the allocated memory area of the BFWD 2.

- Mixed mode, in which part of the information is processed in BFWRD 2, part in the software on PC 1.

At the applicant enterprise:

- developed design documentation, which produced the installation of the inventive utility model (Fig. 2);

- developed a software package that provides the utility model.

The implementation of the utility model allows the performance test and the search for faulty elements of digital and analog devices.
