<p>CENTO is a multifunctional software platform for data collection, processing, and display. It can be used to build various automated systems, including dispatching, electricity and energy resource metering, emergency event registration, power quality control, monitoring, and diagnostics.</p>

148

<p>This document describes the CENTO structure and lists all CENTO components, each with a brief description.</p>

<p>The general structure of CENTO is shown in Fig. 2.1. CENTO consists of two main blocks:</p>

153

154

<li><strong>Web part</strong> — provides data to users and contains system configuration tools. Information is delivered via a web browser.</li>

155

<li><strong>Core of the system</strong> — a set of applications running all CENTO components, responsible for collecting, transmitting, processing, and storing data.</li>

</ul>

<p>The CENTO web interface is built on the <strong>nginx</strong> web server, web application modules (PHP and executable services), and a web browser on the client side. Key infrastructure components:</p>

167

168

<li><strong>MongoDB</strong> — NoSQL database storing system configuration, event logs, mimic diagrams, and their components.</li>

169

<li><strong>InfluxDB</strong> — NoSQL time-series database storing data collected by the system.</li>

170

<li><strong>NATS</strong> — message broker for inter-component data exchange.</li>

174

<p>The core consists of polling and data transmission services, processing services, and auxiliary services.</p>

175

176

<p><strong>Polling and data transmission services</strong> collect data from information sources and transmit it to external systems via the message broker. Certain polling services include binary files <code>sed_metrology_XXX.bin</code> — the metrologically significant part containing data extraction mechanisms and register configurations for the polled devices.</p>

177

178

179

<div class="note-body">When metrologically significant files change, their checksum changes. Checksums are shown on the <strong>Services</strong> tab of <strong>System Information</strong> (Settings → System Information) and are calculated using the MD5 algorithm. Click <strong>Update Information</strong> to refresh.</div>

</div>

<p class="fig-cap">Fig. 3.1 – Updating checksums of metrologically significant files</p>

184

</div>

185

186

<p><strong>Data processing services</strong> receive data from the message broker, process it, and write it to the database. Processing services include metrologically significant files <code>sed_metrology_YYY.bin</code> containing algorithms for calculating measured values. The <code>sed_calc_arch</code> service additionally has <code>sed_metrology_formulas.bin</code> for custom pre-calculation formulas marked as metrologically significant.</p>

187

<p><strong>Auxiliary services</strong> ensure the main CENTO services can perform their functions (license management, watchdog, scheduling, backup, replication, etc.).</p>

188

<p>The composition of CENTO services for a given installation depends on its configuration and is shown on the <strong>System Information</strong> tab.</p>
