4.5 Рекомендации по защите пользователей от излучений эвм

При подборе вычислительной техники следует отдавать предпочтение мониторам с низкими уровнями излучений, отвечающим шведским стандартам MPR 1990:8, MPR 1990:10, ТСО 91 и повышенными визуальными характеристиками.

На мониторы рекомендуется устанавливать защитные фильтры класса полной защиты (Total shield), обеспечивающие практически полную защиту от всех вредных воздействий монитора в электромагнитном спектре и позволяющие уменьшить блик от электронно-лучевой трубки, а также повысить читаемость символов.

4.6. Выводы

Используемые методы и способы по защите от воздействия опасных и вредных факторов и соблюдение эргономических требований обеспечивают безопасность разработчика и пользователей.

Заключение

В соответствии с техническим заданием был дан общий обзор области, к которой относится тема дипломной работы, рассмотрены и проанализированы альтернативы для реализации поставленной задачи. Программный комплекс OMNET++ и симулятор Castalia, по результатам анализа, признаны отвечающими поставленным требованиям.

Был дан обзор возможностей и функционала беспроводных сенсорных сетей на базе стандарта 802.15.4. Приведены расчеты эффективной скорости передачи данных, энергопотребления и времени работы при заявленной и рассчитанной скорости.

В ходе выполнения дипломного проектирования была построена событийно-имитационная модель беспроводной сенсорной сети, на ее основе сымитирована работа и определено максимальное время работы сети (130 часов).

В технологической части изложен процесс установки, настройки и проверки работоспособности программного комплекса OMNET++ и симулятора Castalia.

В разделе «Экономическая часть» был проведен анализ экономической эффективности данного дипломного проекта.

В разделе «Охрана труда» приведены обзор и рекомендации по защите здоровья от вредных и опасных факторов, возникающих при работе с ЭВМ, таких как: поражение электрическим током и влияние излучение монитора на здоровье человека.
