Research on active safety monitoring and early warning system for lithium ion battery energy storage power stations based on wireless sensor networks

“…(1) Power supply voltage: 3.0V-5.5V, another power supply method is powered by data cable; (2) Single line interface mode, enabling bidirectional communication with microprocessors using only one line; (3) Support multi-point networking. Multiple DS18B20 can be used in parallel to achieve multi-point electrical measurement; (4) No peripheral devices are required during operation, and all sensor components and conversion circuits are integrated internally; (5) The measured electrical range is -55 ℃~+125 ℃, with an accuracy of up to ± 0.5 ℃; (6) The resolution is 9-12 bits, achieving high-precision electrical measurement; (7) The resolution determines the conversion rate, and the electrical can be converted into numbers within a maximum of 750ms; (8) Negative pressure characteristic: When the power line is connected in reverse, it will not cause damage to the chip, but it cannot work properly. The electrical parameters collected mainly include three-phase voltage, three-phase current, frequency, power, phase angle, power factor, etc.…”

“…The power system frequency modulation signal is decomposed into high-frequency and low-frequency components, and the electrochemical energy storage system bears the high-frequency component [4]. the research on knowledge learning based health monitoring and warning for energy storage power plants aims [5][6] to design a health monitoring and warning system based on kernel density estimation and Long Short Term Memory (LSTM) model for the individual health problems of energy storage power plant systems in operation. The system consists of two parts, one is a health assessment module based on kernel density estimation [7], This module can conduct periodic inspections of all energy storage batteries inside the energy storage station.…”
