RFID Cable Tags Ldeal For Safety Inspections

RFID cable tags revolutionize power cable monitoring with wireless, real-time temperature tracking. Overcome traditional limitations with passive, multi-point sensing (±1°C accuracy) for joints, tunnels & harsh environments. Enhance grid safety, prevent faults & optimize maintenance with smart RFID temperature measurement technology.

1.RFID temperature measurement technology principle

RFID (radio frequency identification technology) based on radio frequency signals to achieve non-contact information interaction in order to reach recognition. In the cable temperature measurement system, it is mainly composed of RFID reader, temperature measurement tags and data processing systems. The reader transmits radio frequency signals, temperature measurement tags into its working range, the tag antenna sensing signals into electrical energy, power supply for the internal circuit. Temperature sensor real-time sensing temperature, the data is converted into electrical signals, coded and modulated to RF signal back. After receiving the signal, the reader demodulates, decodes and transmits the temperature data to the data processing system. The system analyzes, stores and displays the data, and alarms immediately when the temperature exceeds the threshold.

2.RFID temperature measurement technology advantages

Passive wireless features: RFID temperature measurement tags do not require external power supply, relying on the reader RF signals to take energy, complete temperature measurement and data transmission. This design makes the tag easy to install, free of wiring troubles, suitable for high insulation requirements, wiring difficult underground cables, cable tunnels and other scenes. Passive design avoids the interruption of monitoring caused by the exhaustion of battery power, and improves the reliability and stability of the system.

High-precision measurement: The accuracy of RFID temperature measurement technology can reach ±1℃, which can keenly capture the subtle changes in cable temperature, accurately determine the operating status, and provide reliable data for early warning of faults.

Strong anti-interference: the power environment is complex electromagnetic interference, RFID system through the optimization of antenna design, selection of appropriate frequency bands, the use of coding and modulation technology, and other means, stable operation in the strong electromagnetic noise, to ensure accurate and reliable temperature data.

Real-time data transmission: The system can collect the cable temperature in real time and quickly transmit it to the processing system. The operation and maintenance personnel can check the temperature changes in real time with the help of monitoring terminals, detect abnormalities and take measures in time to effectively prevent accidents.

Multi-target identification: A single RFID reader can simultaneously identify multiple temperature measurement tags, synchronized monitoring of multiple temperature measurement points on the same cable line, significantly improving the monitoring efficiency and reducing costs, suitable for large-scale cable networks.

Good environmental adaptability: RFID temperature measurement tags are specially encapsulated to work stably in harsh environments such as high temperature, high pressure, humidity, corrosion, etc. Whether it is an outdoor substation or an underground cable trench, it can ensure the continuity and accuracy of temperature monitoring.

Cable key parts monitoring

1. cable joints: as a high failure point, RFID temperature measurement tags are arranged in the conductor connection part, insulation surface and shielding layer to monitor the temperature in all directions. 2. cable body: according to the cable length, load and operating environment, temperature measurement points are set every 100-200 meters for long cables.

2. cable body: according to the cable length, load and operating environment, long distance cable every 100-200 meters to set up temperature measurement points; load or harsh environment section of the appropriate encryption.

3. cross interconnection box: in the box cable connection parts, switch contacts and box shell arrangement of temperature measurement tags, monitoring temperature anomalies.

System Architecture

1. Sensing Layer: RFID temperature measurement tags of snap type, tie type and inlay type are used to collect temperature data according to the installation location and environment selection. 2.

2. Transmission layer: composed of RFID reader and communication network. The reader reads the data and transmits it to the data processing system through wired (fiber optic, Ethernet) or wireless network, and selects the communication mode according to the scene.

3. data processing layer: data processing system analyzes, stores and processes temperature data, predicts temperature trends; monitoring platform visually displays data, status and alarm information, and supports multi-terminal access.

System function realization

1. real-time monitoring: real-time temperature collection, presenting figures and charts on the monitoring platform to show the overall temperature distribution. 2. alarm function: the user can set the alarm function.

2. alarm function: the user sets the alarm threshold, the system sends out sound and light and SMS alarms when the threshold is exceeded, and records the alarm information.

3. Historical data processing: automatically store not less than 1 year of historical data, support query and analysis, such as drawing trend curves, statistics, the number of anomalies.

4. Fault diagnosis and prediction: use algorithms to diagnose faults by combining operating parameters and ambient temperature, and predict abnormalities through historical data modeling for early warning.
