Bus terminal controller, bus communication power supply system and communication power supply method thereof

Abstract

The invention relates to the technical field of bus communication, and particularly discloses a bus terminal controller, a bus communication power supply system and a communication power supply method thereof. The bus terminal controller comprises a circuit board (100), and a second MCU module (200), a DC-DC circuit module (300), an open circuit and short circuit detection module (400), a second driving circuit module (500) and an RX-TX circuit module, which are arranged on the circuit board, wherein the second driving circuit module, the open circuit and short circuit detection module and the RXTX circuit module (1400) are all connected with the second MCU module, and the DC-DC circuit module is connected with the RX-TX circuit module; the DC-DC circuit module is connected with a bus power supply communication circuit module (600); the second driving circuit module comprises a code receiving module (501) and a code sending module (502) which are connected with each other; and the code sending module and the code receiving module are both connected with the second MCU module. The device has the advantages that the size is small, signals cannot be interfered, and the monitoring accuracy cannot be affected.

Description

technical field [0001] The invention relates to the technical field of bus communication, in particular to a bus terminal controller, a bus communication power supply system and a communication power supply method thereof. Background technique [0002] Micro control unit MCU, also known as single-chip microcomputer or single-chip microcomputer, is to appropriately reduce the frequency and specifications of the central processing unit, and integrate peripheral interfaces such as memory, counter, USB, A / D conversion, UART, PLC, DMA, and even LCD. The drive circuits are integrated on a single chip to form a chip-level computer, which can be controlled in different combinations for different applications. At present, the MCU is mainly used for the control of mobile phones, PC peripherals, remote controls, automotive electronics, industrial stepping motors, robotic arms and fire monitoring systems. The fire monitoring system generally includes fire emergency lighting and evacuat...
