Abstract

The invention discloses a Wi-Fi intelligent line aging monitoring device which comprises a monitoring device body, the monitoring device body comprises a monitoring system, and the monitoring system comprises a main controller module, and a current constant current output module, a voltage acquisition system, an OLED display screen module and a Wi-Fi module which are in signal connection with the main controller module. The current constant current output module is used for inputting constant current to a detected line; and the voltage acquisition system is used for acquiring voltages at two ends of a measured line and transmitting a monitored voltage value to the main controller module. The device is reasonable in design, convenient to use, low in power consumption, high in detection accuracy and suitable for long-time operation, can effectively avoid the fire phenomenon caused by line aging, and is beneficial to market-oriented popularization and application.

Description

technical field [0001] The invention relates to the technical field of fire early warning, in particular to a Wi-Fi intelligent line aging monitoring device. Background technique [0002] With the continuous development of the social economy, people's living standards continue to improve, the degree of electrification is getting higher and higher, and the scope of use of electrical equipment is expanding. High-power appliances such as air conditioners and water heaters are used in the home. In the early years, the line aging is very serious, and the cables are generally buried inside the wall, and people cannot directly observe the aging of the cables with the naked eye. Long-term operation of high-power electrical appliances can easily lead to overheating of cables, burning out the insulation layer of wires, and causing electrical fires. [0003] Traditional line aging monitoring devices generally use infrared thermometers to detect the temperature of cables in the wall, a...
