With the development of electrification and informatization, the electromagnetic environment is becoming more and more complex, which has a profound impact on human life and health. In order to ensure the health and safety of electromagnetic environment, on-line monitoring of electromagnetic environment is becoming more and more important. Let's discuss the significance, technical means, application scenarios, advantages and future development trends of online monitoring of electromagnetic environment.
1.The significance of electromagnetic environment online monitoring
The electromagnetic environment online monitoring can monitor the electromagnetic radiation intensity, spectrum distribution and other parameters in the electromagnetic environment in real time, find the electromagnetic environment pollution and abnormal situation in time, and ensure the public health and property safety. In addition, through the online monitoring of the electromagnetic environment, the characteristics and laws of the electromagnetic environment can be better understood, which provides a scientific basis for the further research and expansion of the application of electromagnetic environmental protection and governance and the extension of protection technology.
2.The technical means of electromagnetic environment online monitoring
The on-line monitoring of electromagnetic environment mainly depends on the equipment and technology such as sensor and data acquisition system. The sensor can sense the intensity, frequency and even polarization of the electromagnetic signal in the electromagnetic environment, and the data acquisition system can collect, process and analyze the data obtained by the sensor. With the development of the Internet of Things and cloud computing technology, online monitoring of the electromagnetic environment can achieve real-time remote monitoring and data sharing, improving the efficiency and accuracy of monitoring.
3. The application scenario of electromagnetic environment online monitoring
On-line monitoring of electromagnetic environment is widely used in environmental protection, industry, scientific research, medical treatment, testing and other fields. In the industrial field, high-voltage transmission lines, transformers and other equipment can be monitored in real time to prevent electrical accidents; In the field of scientific research, electromagnetic wave sources and electromagnetic radiation effects can be deeply studied; In the medical field, the effects of electromagnetic radiation on the human body can be assessed and monitored.
4.The advantages of electromagnetic environment online monitoring
The automatic working system of on-line monitoring of electromagnetic environment has the advantages of high accuracy, strong real-time and easy maintenance. Through real-time monitoring and data sharing, abnormal situations can be detected in time, response speed and accuracy can be improved, and emergency mechanisms can be arranged in advance. At the same time, online monitoring can be automated and intelligent, reducing the cost of manual extensive testing and maintenance.
5. Some typical cases from other countries and regions
Greece: The Hellenic National Electromagnetic Field Observatory is organized as a network platform consisting of 500 fixed (480 broadband and 20 selective frequency) and 13 mobile (on-board selective frequency) measuring stations throughout Greece, continuously monitoring electromagnetic field levels from various antenna stations in the frequency range of 100kHz - 7GHz.
Romania: Measurements using portable devices and online monitoring devices via Bucharest and 103 other regions of the country (located in educational institutions, hospitals, public areas of institutions, gathering areas (such as train stations, markets, etc.) or public areas where there are concentrations of electromagnetic field sources nearby.
Paraguay: Provides real-time results of the National Telecommunications Commission (CONATEL) electromagnetic field intensity measurements through 31 fixed monitoring sensors installed in the city center.
Serbia: The selection of monitoring points is mostly educational institutions, hospitals, public areas of institutions, gathering areas (such as railway stations, markets, etc.) or nearby public areas where electromagnetic field sources gather. In addition to the Protection against Non-Ionizing Radiation Act, secondary legislation also provides for more detailed regulation of the modalities of examination in the field of emerging markets.
6. Future development trend
With the continuous progress of science and technology, electromagnetic environment online monitoring will develop in the direction of intelligence, networking and mobility. Intellectualization can achieve more accurate monitoring and data analysis, networking can achieve more extensive data sharing and remote monitoring, and mobility can realize monitoring and emergency response anytime and anywhere. In addition, the future online monitoring of the electromagnetic environment will be more applied to environmental protection, public safety, smart cities and other fields, and make greater contributions to the development of human society.
In short, on-line monitoring of electromagnetic environment is of great significance to ensure the health and safety of electromagnetic environment. With the continuous progress of technology and the expansion of application scenarios, online monitoring of electromagnetic environment will play a more important role and provide strong support for the sustainable development of human society.
