Description

Technical Field

[0001] This utility model relates to the field of industrial automation, and in particular to an environmental monitoring system for thermal power plants based on SIS wireless transmission. Background Technology

[0002] In the field of environmental monitoring data transmission in thermal power plants, transmission methods have evolved from wired fiber optics and 4G to wireless transmission modules. While early wired fiber optic transmission offered advantages such as stable data transmission, high speed, and strong anti-interference capabilities, infrastructure construction required laying optical cables and pipelines, resulting in high costs. Furthermore, it was constrained by spatial factors such as complex plant terrain and equipment mobility requirements, leading to extremely poor flexibility. 4G card transmission, while overcoming spatial limitations and enabling data transmission from mobile devices or dispersed locations with relatively flexible deployment, required long-term data usage fees, resulting in high operating costs. In areas with poor signal coverage, transmission instability could also occur. The currently used wireless transmission module, through channel and rate matching between devices A and B, allows device A to broadcast data, which is received by device B and transmitted to a computer via a serial port. After data processing, the data is entered into a database and ultimately used to analyze the impact of meteorological factors on particulate matter concentration, improving monitoring accuracy. This method is not only highly flexible and suitable for deployment at dispersed monitoring points, but also reduces the costs of wired infrastructure and 4G data usage, supports data tracking and multi-factor analysis, and effectively improves the effectiveness, accuracy, and stability of predictions. However, wireless transmission modules also have significant shortcomings: numerous buildings, equipment, pipelines, and other obstructions within the power plant area can hinder wireless signal propagation, leading to data transmission delays, interruptions, and increased packet loss rates; the signal strength of power frequency antennas is relatively weak, making it difficult to cover dense spaces such as workshops and multi-story buildings, easily resulting in data transmission "blind spots"; and the exposed wireless transmission antennas are susceptible to damage from lightning strikes during thunderstorms, affecting transmission continuity and increasing maintenance costs. To address these issues, high-gain directional antennas or the use of mesh networks can improve signal penetration and coverage; adding relay equipment in dense spaces can reduce the impact of obstructions; installing lightning protection devices on antennas, optimizing installation locations, and selecting wireless frequency bands with stronger anti-interference capabilities can reduce packet loss rates; and combining wired / wireless hybrid modes or adding retransmission mechanisms to wireless transmission can ensure no data loss, thereby further leveraging the flexibility of wireless transmission modules and more reliably supporting the accurate monitoring of air quality in power plants.
