Purpose

Software-Hardware Complex «Atlant» (further — the Complex) is a complex of devices which allow to create the equipment sets and systems (further — the equipment set) of different structure and purpose. There have been already some the equipment sets on the base of SHC «Atlant» that are available to solve such tasks:

• a technological control;
• a control of the radiation situation at facilities which connect with obtainment, processing, use and disposal of radioactive materials;
• an execution of functions of the automated radiation safety monitoring and automated radiation situation monitoring system at the radiation-hazardous facilities;
• the researches in the scientific-research and higher educational establishments on the various accelerators and reactors;
• to control the radiation doses of patients and staff in the health facilities.

An integration of the climate sensors and flow meters in the composition of measuring devices of SHC «Atlant» was allowed to use software-hardware complex in the animal husbandry and agriculture.

Architecture

Software and Hardware Complex has a four-level architecture — Lower, Middle, Upper and User level. A logical scheme of such system is shown at Figure 1.

Figure 1. A logical scheme of complex «Atlant»

Lower level

A lower level of complex consists of the primary measuring devices (matching devices, radiation detectors), sensors, alarm systems — OSS-02, UIM-Т1, consoles of lower level — USR-03, USR-04 and etc. The devices of lower level are connected by an information highway.
A full list of lower-level devices is shown below. The detailed composition and image of these devices can be found in the document Software-Hardware Complex «Atlant». Information about the consoles USR-03 and USR-04 is given in «General information about the console USR-04».

Middle level

A middle level of Complex consists of a central console which is controlled by the software «Atlant».
The following can be used as the central console:

• a central panel unit CPU-103;
• a central panel unit CPU-104 in the base of personal computer.

The central console is intended:

• to poll of lower-level devices;
• to display of measuring information and messages about the status of devices;
• to transfer of operational information to a database server.

Note. Availability of the central console isn't compulsory. In case of absence of such device the console of lower level (USR-03 or USR-04) executes partially its functions (displaying information and polling lower-level devices)

Upper level

The servers create the upper level of the equipment set:

• WEB-server and Internet server;
• a database server with an installed software «Atlant-Protocol».

The software «Atlant-Protocol» provides the controlled access of authorized users to the information of a database server.

User level

The User Level consists of some quantity of users of individual workstations registered in the «Atlant-Protocol» and having access to the database server via the local network or the Internet.

Note. As the software of User Level can be used any Internet-browser installed on the user's PC.

Information highway of Complex

A data exchange in the information highway provides:

• at the software level — by DiBUS protocol;
• at hardware level — by RS-422 (RS-485) with using of the cable communication lines.

Figure 2. Branching of IH by means of a junction box

IH connects in the central console and lower-level devices in the unified system. The following technical solutions are used for branching IH, connecting remote devices to the system:

• branching of IH with using of the junction boxes (КК-1, КК-2, КК-2-6) (Figure 2). Outputs of IH can optionally be used to branch of IH, or connect of lower-level devices;
• elongation of IH at the distance more 1200 m with using of a network translator (ТС-01) (Figure 3);
  
  Figure 3. Elongation of IH at the distance more 1200 m

• multiple elongation of IH (Figure 4);

Design of the the equipment sets

Possible types of lower-level devices

Almost all measuring devices produced by SPE «TETRA» Ltd can be used as the lower-level devices:

• which measure the characterises of radiation fields;
• which control movement and detection of sources of ionizing radiation;
• radioisotope density meters, level gauges, gamma relays.

The equipment set may include devices that use information from standard sensors:

• climate control — temperature, humidity, pressure, wind speed and direction;
• flowmeters.

The use of various matching devices makes it possible to include measuring devices of third-party organizations in the equipment sets «Аtlant».

The equipment set options

Hardware consolidation of upper-level servers is acceptable in case of small the equipment sets (with no more than fifty lower-level devices).
A smaller number of serviceable devices of the equipment set allows the hardware integration of the central control unit with the servers of the upper level.
The simplest the equipment sets may consist of only lower and middle level devices.

Integration of the equipment set «Аtlant» into existing systems

The equipment set «Аtlant» is easily configured to work with the database server of an already existing «foreign» system.
With a given frequency and reference to a single system time, the central control panel generates informational messages received by relational DBMS (such as MySQL, PostgreSQL, Oracle, InterBase, Firebird, MSSQL, SQLite ...)
Thus, it is possible to access the «foreign» system to the data of the equipment set «Аtlant».

Construction of own the equipment sets based on lower-level devices of SHC «Аtlant»

Our company provides information support to consumers and customers who intend to create their own systems and the equipment sets using the devices of the SHC «Аtlant».
The site contains the following documents containing comprehensive information for the developer:

• the description of the exchange protocol;
• the lists of registers of each «intelligent» device of SHC «Аtlant»;
• a set of free technological software.

Integration of devices of other developers into SHC «Аtlant»

A well-established method of introducing «foreign» intelligent devices into the SHC «Аtlant» software and hardware complex is the manufacture of an auxiliary intermediate device called a matching unit of protocols (BSP-xx, where xx — the execution number).
