This is done via the <code>add_attention_data<\/code> function, which simply puts <code>attention_features<\/code> into the queue. In a normal operational mode, external components would call this function to provide visualization data. In demo mode, synthetic data generated by <code>generate_demo_data<\/code> is periodically added to this queue.<\/li>\n\n\n\n<li><strong>Queuing Mechanism<\/strong>: The <code>attention_queue<\/code> acts as a buffer, storing incoming attention data until it can be processed and sent to clients.<\/li>\n\n\n\n<li><strong>Producer Handler<\/strong>: For each connected client, a <code>producer_task<\/code> runs a <code>producer_handler<\/code> asynchronously. This handler is responsible for sending attention data to the specific client&#8217;s WebSocket.\n<ul class=\"wp-block-list\">\n<li>The <code>producer_handler<\/code> <strong>continuously checks the <code>attention_queue<\/code><\/strong> for new data, specifically every 100 milliseconds using <code>asyncio.sleep(0.1)<\/code>.<\/li>\n\n\n\n<li>When new <code>attention_data<\/code> is available in the queue (i.e., <code>while not attention_queue.empty():<\/code>), it retrieves the data using <code>attention_queue.get()<\/code>.<\/li>\n\n\n\n<li>The retrieved <code>attention_data<\/code> is then processed by an instance of <code>SignalAttentionVisualizer<\/code> to <strong><code>generate_radar_sweep_data<\/code><\/strong>. This suggests the raw attention data is transformed into a format suitable for visualization, perhaps for a radar-like display.<\/li>\n\n\n\n<li>The processed <code>radar_data<\/code> is then <strong>converted into a JSON string<\/strong> (<code>json.dumps(radar_data)<\/code>).<\/li>\n\n\n\n<li>Finally, this JSON message is <strong>sent directly to the connected client<\/strong> via <code>await websocket.send(message)<\/code>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Client Connection Management<\/strong>:\n<ul class=\"wp-block-list\">\n<li>When a new client connects, the server&#8217;s <code>handler<\/code> function calls <code>register<\/code> to add the client&#8217;s WebSocket to a set of connected clients, and logs the new connection.<\/li>\n\n\n\n<li>If a client disconnects or an error occurs (like <code>websockets.exceptions.ConnectionClosed<\/code>), the <code>unregister<\/code> method is called to remove the client from the set.<\/li>\n\n\n\n<li>While the <code>producer_handler<\/code> sends data to individual clients, the server also has a <code>broadcast<\/code> method that can send a message to <em>all<\/em> connected clients simultaneously, although the attention data flow specifically uses the <code>producer_handler<\/code> for each client.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Server Operation<\/strong>: The <code>AttentionVisualizerServer<\/code> initializes with a <code>SignalAttentionVisualizer<\/code> instance. The server can be started in a <strong>background thread<\/strong> using <code>start_background_server<\/code>, which runs the <code>start_server<\/code> method using <code>asyncio.run<\/code>. This setup ensures the server continuously listens for new connections and manages data flow.<\/li>\n<\/ul>\n\n\n\n<p>In essence, incoming attention data is queued, and multiple &#8220;producer&#8221; tasks, one for each connected client, pull from this shared queue, transform the data, and send it in real-time over individual WebSocket connections.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>PODCAST: explore the RF_QUANTUM_SCYTHE Signal Attention Visualizer Server, a WebSocket server designed to display real-time signal attention maps.
