Intelligent distribution transformer terminal of power distribution room based on internet of things perception

Abstract

The invention discloses an intelligent distribution transformer terminal of a power distribution room based on internet of things perception, and relates to the technical field of intelligent distribution transformer terminals. The intelligent distribution transformer terminal comprises a switch quantity input module, a switch quantity output module and an analog quantity collection module; the switch quantity input module, the switch quantity output module and the analog quantity collection module all are connected with a CPU via an AHB bus; the CPU extends eight paths of standard RS485 communication interfaces via an SPI module; the SPI module is connected with a serial port communication interface module; the CPU is connected with an MAC controller via an RII interface; and the CPU is connected with a 4G wireless communication module via the AHB bus. According to the intelligent distribution transformer terminal, by collecting information of an aftercurrent action protector, the detection on information such as an on-off state, an aftercurrent value, a voltage, a current and an event alarm of the aftercurrent action protector is implemented; and by collecting environmental temperature and humidity and configuring parameters in advance, the temperature-humidity adjustment to an electric transformer and distribution place is facilitated.
