Monitoring system based on power supply bus information

Abstract

The invention discloses a monitoring system based on power supply bus information. The monitoring system comprises a power supply conversion circuit which is used for converting the inputted power supply into voltage of different volt values to be supplied to normal working of the corresponding circuits in the monitoring system; a bus power output circuit which is used for outputting and enhancing the working power of bus signals; a communication isolation circuit which is used for isolating the signals of an interference source and the part liable to be interfered; a fault monitoring circuit which is used for monitoring the fault of communication signals and power supply signals transmitted in the system; and a communication control circuit which is used for controlling the power supply conversion circuit to output different levels of voltage values to be supplied to the monitoring system, controlling the output power of the bus signals in the bus power output circuit and monitoring the output power in real time, controlling and actuating the communication isolation circuit to realize isolation of the related signals and the corresponding power supply signals and further controlling the fault monitoring circuit to complete fault monitoring of the data communication transmission signals and the power supply signals so as to realize fault emergency processing.

Description

technical field [0001] The invention relates to the field of information monitoring, in particular to a monitoring system based on power bus information. Background technique [0002] This technology is applied to the fire door monitoring system. Through the main station control circuit of the power bus (PowerBus) bus, the two-wire bus technology that can supply power is used to realize the power supply of the fire door monitor host to the fire door terminal actuator, as well as the main, Data transfer function between slave devices. [0003] With the rapid development of my country's economy, the construction industry has shown a steady upward trend. With the gradual comprehensive development of buildings, the high risk of fire in large enterprises and various high-rise buildings has become increasingly prominent, especially in high-rise buildings and large public buildings. The traffic routes are intricate and complex, and there are many fire hazards. At present, the coun...

Problems solved by technology

Most of these systems use DC 24V power supply equipment. The communication bus generally adopts RS485 and CAN bus. The field wiring generally adopts a four-wire system (two power supply lines and two communication lines). Large, it is inconvenient to troubleshoot line problems, and it also increases the difficulty and cost of maintenance
