Abstract

The present invention discloses an on-line monitoring device and a monitoring method for the working state of a copper-aluminum composite connection terminal. The device comprises a microprocessor module. The microprocessor module is connected with a Beidou positioning module, an environmental temperature and humidity sensor, a temperature sensor and a current sensor, and is also connected with a monitoring terminal through a wireless communication module. The environmental temperature and humidity sensor is used for measuring the ambient temperature and the ambient humidity of the connection terminal. The temperature sensor is used for measuring the temperature at the connection terminal. The current sensor is used for measuring the current flowing through the connection terminal. According to the technical scheme of the invention, through the acquisition processes of the environmental temperature and humidity sensor, the temperature sensor and the current sensor, acquired data are transmitted to the monitoring terminal through the wireless communication module, so that the on-line real-time monitoring for the connection terminal is realized. The monitoring reliability is greatly improved. Meanwhile, based on the wireless transmission, no cable is adopted, and both the short-term monitoring and the long-term monitoring are realized. Moreover, through a positioning module, a fault point can be found out conveniently, so that a fault can be quickly found out. Therefore, the maintenance efficiency is greatly improved.

Description

technical field [0001] The invention relates to an online monitoring device and a monitoring method for the working state of a copper-aluminum transition connection terminal, belonging to a monitoring device for the working state of a copper-aluminum transition connection terminal. Background technique [0002] my country is rich in aluminum but poor in copper resources. As my country's second largest strategic material after oil, copper is 70% dependent on imports. At the end of 2013, the National Development and Reform Commission and the Ministry of Industry and Information Technology have determined the strategic direction of using aluminum to save copper, and using aluminum to save copper has become a hot spot in various industries. Because the aluminum alloy material not only has the high electrical conductivity and thermal conductivity of copper, but also has the advantages of low price, light weight, corrosion resistance, beautiful appearance, and economy. Therefore,...
