Abstract

The invention discloses an Internet of Things terminal supporting relay protection service. The Internet of Things terminal comprises an Internet of Things characteristic CPU, a real-time CPU, an Ethernet communication interface, a serial communication interface, a remote wireless communication module, a Beidou / GPS module, a local wireless communication module, a switching value input circuit, a switching value output circuit, an alternating current analog quantity input circuit and a communication bus between the Internet of Things characteristic CPU and the real-time CPU. The internet of things terminal not only has a function module of a conventional internet of things terminal, but also expands functions of the internet of things terminal, supports real-time acquisition of switching value input, switching value output and alternating current analog quantity input, identifies short-circuit faults occurring in transformers, lines and the like in real time, isolates fault parts, prevents fault range expansion, and prevents damage to further power equipment. Through function expansion of a conventional Internet of Things terminal, the value of the Internet of Things terminal is improved, and the application scene of the Internet of Things terminal is expanded.

Description

technical field [0001] The invention relates to the technical field of electric power internet of things, in particular to an IoT terminal supporting relay protection services. Background technique [0002] The construction of the power Internet of Things involves the infrastructure construction of the power grid for power transmission and the communication network for information transmission. The Internet of Things and cloud computing technology can provide important technical support for the construction, operation and management of smart grids from the environment of end users' electrical equipment, equipment operation status, and massive data security. [0003] During the construction of the power Internet of Things, a large number of IoT terminals need to be equipped. Conventional IoT terminals have uplink communication function modules and local communication function modules; the uplink communication function module collects the status information of IoT terminals in...
