Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 As shown, the cable bodies 1 and 3 and the cable intermediate connector 2 are embedded with a wireless temperature collector 4 . The host 5 has the capability of electromagnetic emission and bluetooth communication, and sends electromagnetic waves to the intermediate joint 2 of the cable. The wireless temperature collector 4 sealed on the metal layer of the cable intermediate joint obtains electric energy to provide power to its own system through the principle of electromagnetic resonance, and then the internal temperature sensor chip collects the temperature and sends the real-time temperature value to the host 5 through the paired Bluetooth. The host 5 provides a serial port to connect to the network module and processes the data into a standard protocol and sends it to the server to realize the online monitoring function of ...

Abstract

The invention relates to a cable intermediate joint wireless temperature sensing device based on electromagnetic resonance. A host possesses wireless power supply and Bluetooth communication capabilities, launches electromagnetic waves to the passive wireless communication temperature sensor in a cable intermediate joint, and organizes temperature data to be standard rules when receiving Bluetooth signals from the passive wireless communication temperature sensor, the standard rules being sent to an Internet network and finally arriving at a server, thereby realizing the management of intelligent on-line monitoring equipment. The cable intermediate joint wireless temperature sensing device employs an electromagnetic resonance principle and a Bluetooth data communication form to realize sensor passive power supply and wireless data acquisition, and makes installation more convenient and faster; the cable intermediate joint is safer in an on-line monitoring process, and collects data more efficiently.

Description

technical field [0001] The invention belongs to the technical field of electric power online monitoring, and relates to a wireless temperature sensing device for a cable intermediate joint based on electromagnetic resonance. Background technique [0002] The existing common electric power on-line monitoring equipment and sensor modules adopt wired power supply and communication bus mode. Since wired transmission is not suitable for fully sealed individual installation conditions. The external host cannot use a wired connection to measure the temperature inside the cable intermediate joint; therefore, the limitation of the wired connection in the measurement work is more obvious in the case of a sealed individual. Contents of the invention [0003] The present invention mainly solves the problem that the original on-line monitoring host equipment cannot directly measure the temperature of the metal layer of the cable intermediate joint. The invention adopts the form of el...
