Description

The utility model relates to the field of electro-radio engineering and can be used to test the equipment of automated communication systems (ACS) of surface ships (NK).

There is a well-known test bench for the control system (SU) of the ACS NK of the Buran type SHEIA.464.541 TO, 2003. Enterprises - developers - plant named after N.G. Kozitsky and FSUE Research Institute "Neptune".

The stand includes a permanently mounted part and a variable part, which is installed only for the test period. The variable part is formed by the elements of the ACS AC, as well as remote communication posts. The permanent part of the stand includes:

- cable diagram;

- power supply network;

- instrumentation;

- simulators (information and control) of the channel equipment of the AKS.

A bench of this composition and structure allows you to check only the ergonomic properties of the ACS in coastal conditions, as well as the interface between the SU and channel facilities.

To test and test the new channel equipment of the AKS NK (radio transmitting, radio receiving devices, radio stations, etc.) or equipment providing the functioning of new communication channels, temporary test benches are mounted on specialized training grounds.

The disadvantage of the tests conducted at these stands is that the volume of tests of ACS NK in coastal conditions taking place on

current moment, does not provide verification and assessment of the whole variety of properties of ACS before its installation on the NK.

At the same time, the practice of testing the AKS has shown that the more thoroughly and comprehensively it is tested in coastal conditions, the fewer comments and shortcomings are revealed on its functioning during ship tests. Obviously, it is much cheaper and easier to carry out the elimination of observations in coastal conditions.

The purpose of the utility model is to expand functionality and increase reliability.

This goal is achieved by the fact that in the stand, consisting of a permanently mounted part, which includes a cable scheme; power supply network; instrumentation and simulators (information and controls) of the ACS channel equipment, in addition to the variable part of the stand, the equipment of the complex under test and its control system are included, and the constant part includes antenna-feeder devices, antenna equivalents, a system of antenna switches, amplifiers and splitters, a simulator interference and an operator loading simulator, while the system of antenna switches, amplifiers and splitters is connected in parallel with the AFU, AFU equivalents, ACS equipment, which The second one, in turn, is connected to the automated workstation of the communications officer (AWS DS), and is also connected to an interference simulator and an operator loading simulator, and the power supply system is connected to all elements of the stand.

In FIG. presents a block diagram of the device. It contains:

1 - antenna-feeder devices (AFU), which ensure the functioning of the ACS in real communication channels. The AFU includes transmitting, receiving and receiving-transmitting antennas of various wave ranges.

2 - AFF equivalents providing secretive tuning and operation of radio transmitting devices.

The program includes a set of modules that allow you to manage various types of hardware, as well as modules that implement various aspects of the user interface.

The composition of the complex and the composition of the user interface are changed without recompiling the program (until it is required to include support for new types of communication tools or new types of user service).

The load simulator and the interference simulator are controlled by the AWS DS via a network through which the AWS sends control commands directly.

Let us consider as an example the control procedure in the KB range. If it is necessary to control the N-th path, the one that includes the KB transmitter, the AWS DS computer makes a request for the status of this transmitter, fixes in its RAM the value of the indicator according to the tuning frequency, operation mode (class of transmitting radiation, transmission speed).

The next step is to send a command to configure the high-frequency path monitoring device in accordance with the indicators read from the RPU. Previously, the initial control signal level is set via the remote control circuit. In this case, the initial level of the control signal at the input of the RPU is in the range exceeding the nominal sensitivity in the corresponding mode by 5-10 times. For KB RPU this level is 5-10 μV.

After the above operations are completed, the control message is transmitted, compared with the sample and the results of the control are displayed on the computer of the AWS DS computer and recorded in the computer's memory (date, time, mode, device reading).

If the path check result is unsatisfactory, the control signal level increases by 20 dB and the control operation is repeated. If the result is positive, the channel is considered conditionally usable, but requiring additional work on

3 - simulator of the work of the operator of the AKS, allowing you to simulate different degrees of load, based on various conditions of the communication environment.

4 - an interference simulator, which allows testing under conditions of intentional interference and, thereby, assessing the noise immunity of the ACS, as well as providing training on the work of operators in interference conditions.

5 - a system of antenna switches, amplifiers and splitters, used for switching, amplifying signals and forking them from the AFU to the receiving means of the ACS.

6 - AKS NK equipment, which is tested at the bench.

7 - an automated workstation for a communications officer (AW DS), which is a combination of hardware and software that provides centralized management of technical equipment included in the communications complex, with the aim of checking them, maintaining them in working condition, and implementing the formation (decomposition) of communication channels and their control.

8 - power supply system is used to provide power to all elements of the stand.

The work of the stand is as follows.

All AWS equipment is checked with AWP DS. For this, the radiowp program is developed, which is an implementation of AWP-DS. It represents the operator, i.e. the duty officer for communication on the possibility of managing and verifying ACS facilities connected to the complex’s control network directly or through transition devices - subscriber access modules.

The text of the program is written in C ++ and is based on libraries. The program at the source level can be ported to any hardware and software platform that supports C ++ and a system API compatible with POSIX or Win 32.

maintenance of equipment included in the path (switches, amplifiers, splitters).

If the result is negative, the channel is considered to be defective.

The proposed stand provides verification of almost all the properties of the purpose of the ACS (timeliness, reliability, communication security, bandwidth, noise immunity, etc.) and allows you to take measures to fulfill the requirements set for them even before installing the complex on the ship, as well as provide complete statistics for calculation of the numerical values of the performance indicators of ACS NK.
