In low-temperature rain, snow, and freezing weather, the accumulation of ice on transmission lines and roads is like a hidden "safety killer", constantly threatening power supply, smooth traffic, and public safety. The FT-JB1H ice thickness sensor launched by Fengtu Technology, with its precise measurement capability, strong environmental adaptability, and wide application scenarios, has become a "technological weapon" to solve the problem of ice prevention, playing a key role in transportation, electricity, meteorology, and other fields.

Core technology: Microwave detection technology, accurately capturing ice accumulation information

The FT-JB1H ice thickness sensor adopts advanced microwave detection technology, which is the core of its precise measurement. When microwave signals penetrate different substances such as ice, water, and air, they will produce reflection signals of different intensities due to differences in the characteristics of the medium. Sensors can accurately calculate the thickness of ice by analyzing the strength and frequency changes of these reflected signals, combined with the ice distribution information in sensitive areas. The measurement accuracy can reach ± 0.1mm, and the maximum measurement thickness is 50mm. At the same time, this technology can effectively distinguish different states such as ice, water, and frost, avoiding false triggering of anti icing measures due to misjudgment (such as mistaking accumulated water as ice), and providing reliable data support for anti icing work.

Compared with traditional manual inspection or infrared temperature measurement indirect judgment methods, microwave detection technology has significant advantages. Manual inspection is not only inefficient and has limited coverage, but also difficult for personnel to reach all monitoring points in adverse weather conditions, and poses safety risks. Infrared temperature measurement is susceptible to interference from environmental factors such as temperature and humidity, resulting in inaccurate measurement results. Microwave detection technology enables non-contact measurement, eliminating the need for direct contact with icy surfaces and avoiding interference with facilities such as electrical wires and road surfaces; Strong environmental adaptability, not affected by severe weather conditions such as rain, snow, thick fog, and low temperatures (-40 ℃ -85 ℃). Even in heavy snowfall and freezing weather, stable data collection can still be achieved; Fast response speed, from detecting ice to outputting data in just a few seconds, can capture the dynamic changes in ice thickness in real time, providing technical support for rapid warning.

　　In the field of electricity: safeguarding the safety of the power grid and preventing icing accidents

In the field of electricity, ice accumulation on transmission lines is an important factor threatening the safe operation of the power grid. When the thickness of ice accumulation exceeds the designed carrying capacity of the line, it may cause serious accidents such as wire breakage, tower collapse, and line tripping, affecting the normal supply of electricity. For example, in the cold northern winter or rare "freezing rain" weather in the south, the problem of ice accumulation on transmission lines is particularly prominent, which brings chain effects to industrial production, residential life, transportation and communication fields, and even triggers regional public safety risks.

The FT-JB1H ice thickness sensor provides a technical means of "real-time perception and precise monitoring" for power grid operation and maintenance. It is usually installed on power towers, and by measuring its own ice accumulation, it can effectively infer the current ice accumulation status of power lines near the power tower. When the icing reaches a certain level, the sensor will trigger an alarm to remind the power department to take timely de icing measures, such as thermal de icing, mechanical de icing, etc., to prevent accidents such as pole collapse and wire breakage caused by icing and ensure the stability and safety of power transmission.

In addition, long-term monitoring data can provide important basis for power grid planning and operation optimization. By accumulating ice accumulation data from different regions, seasons, and weather conditions, the operation and maintenance department can analyze the patterns of ice accumulation on transmission lines. For example, in a certain region, the period from December to February of the following year is a high incidence of ice accumulation, and the thickness of ice accumulation is positively correlated with the duration of low temperatures and rainfall. Based on this, targeted prevention and control plans can be developed in advance, such as deploying sensors in areas with high ice accumulation rates, conducting early maintenance of ice melting equipment, and storing emergency supplies; At the same time, these data can also provide reference for the design of new transmission lines, such as selecting anti icing towers in areas with severe ice accumulation, increasing the cross-sectional area of conductors, and improving the anti icing ability of the lines themselves.

　Transportation sector: Ensure smooth roads and reduce accident risks

Road icing is a major safety hazard for winter traffic. The friction coefficient of icy roads drops significantly by 60% to 80%, which can easily lead to traffic accidents, especially sudden accidents caused by "black ice" (transparent thin ice). During periods of poor visibility and high accident rates such as night or early morning, it poses a serious threat to drivers. According to data from the European Road Safety Association, monitoring and warning of road icing can reduce accident rates such as skidding and rear end collisions by over 30%.

The application of FT-JB1H ice thickness sensor in the field of transportation provides a safeguard for road safety. It can be installed on the roadside poles or bridge guardrails of key road sections such as highways, urban roads, and cross river bridges, to monitor the ice thickness of the road surface and bridge deck in real time. By combining meteorological data such as temperature, precipitation, and wind speed collected by meteorological monitoring stations, it is possible to effectively predict the risk of road icing and issue warning information in advance. These information can be timely pushed to the public through linked traffic guidance screens, navigation software (such as Amap/Amap), broadcasts, etc., reminding drivers to drive cautiously; At the same time, the maintenance department is automatically notified to initiate de icing operations, such as spreading vehicles, snow melting agent spraying, etc., to respond quickly and reduce the impact of icing on traffic.

In some high-risk road sections, such as bridges, tunnel entrances, steep slopes, bends, etc., due to their own structural or topographical characteristics, icing is more likely to occur. Encrypt and deploy FT-JB1H ice thickness sensors in these areas to promptly detect icing conditions and take corresponding traffic control measures, such as speed limits and closed road sections, to ensure traffic safety. In addition, the sensor also supports linkage control of intelligent de icing equipment, deploying remotely controllable snow melting agent spraying devices or electric heating road surface systems on key road sections to achieve automated de icing and improve de icing efficiency.

Meteorological field: Enhancing early warning capabilities to assist scientific decision-making

Meteorological conditions have a significant impact on road icing and power line icing. In the field of meteorological monitoring, the FT-JB1H ice thickness sensor can be used as a supplementary monitoring equipment for meteorological stations, deployed in weak meteorological observation areas such as mountainous areas and plateaus, to collect real-time ice data. These data provide practical basis for meteorological departments to issue "road icing warning" and "wire icing warning", which helps to improve the accuracy and pertinence of meteorological warnings.

By analyzing a large amount of historical ice accumulation data, meteorological departments can establish ice accumulation prediction models, combine meteorological forecast information, and predict the occurrence time, location, and degree of ice accumulation in advance, providing scientific reference for relevant departments to formulate anti icing measures. For example, when low-temperature rain and snow weather is expected to occur, the meteorological department can use the ice accumulation prediction model to notify the power department in advance to strengthen monitoring and protection of transmission lines, and notify the transportation department to prepare for road de icing, thereby effectively reducing the losses caused by ice accumulation disasters.

Easy installation, strong adaptability, meeting diverse needs

The FT-JB1H ice thickness sensor is designed to balance practicality and adaptability. It has a small size, light weight, and simple installation process. For power facilities, it can be directly fixed on the power tower. By measuring the ice accumulation of the sensor itself, the ice accumulation status of nearby power lines can be judged equally, without the need to be directly installed on the power line, avoiding affecting the operation of the line; For roads and bridges, they can be installed on roadside poles and bridge guardrails to monitor the icing situation on the road surface and bridge deck.

Fengtu Technology FT-JB1H ice thickness sensor plays an important role in transportation, power, meteorology and other fields with its advanced microwave detection technology, accurate measurement capability, wide application scenarios and strong environmental adaptability. It not only provides scientific data support for anti icing work, effectively prevents accidents caused by ice accumulation, ensures the production and living order of society, but also promotes the development of related industries towards intelligence and refinement. With the continuous advancement of technology, the FT-JB1H ice thickness sensor is expected to be applied in more fields, making greater contributions to ensuring public safety and promoting social development.
