Intelligent safety protection management host

Abstract

The invention discloses an intelligent safety protection management host which comprises a display module, a control module, an alarm output module, a heat dissipation module, a data processing module, an analog input module, a digital input module, a video input module, a power module, a network communication module and a protocol conversion module. Modularized customization is adopted, two ARM9processors are configured, and faults of a main processor are automatically switched; the specified point location data transmission rate can be adjusted according to the point location polling frequency requirement; a plurality of devices in the same local area network can allocate network bandwidths according to the number of point locations and polling frequency requirements, and intelligent and cooperative work is realized; and the intelligent safety protection management host supports digital signals, analog data and monitoring video input and RS-232, RS-485 and CAN bus communication, canautomatically retrieve nearby monitoring pictures when an alarm signal is received, supports data wireless and wired transmission and support flexible check of the data through a management computerand a mobile terminal, and is widely applied to building safety protection system engineering.

Description

technical field [0001] The invention discloses an intelligent safety protection management host, which belongs to the field of intelligent buildings. Background technique [0002] China's intelligent building industry has experienced a long development process from scratch, from small to large, from complete dependence on imports to independent research and development of products and even overseas sales. The intelligent building industry has undergone earth-shaking changes. Compared with European and American countries, the popularity of building intelligence in my country is still relatively low, and there is a broad market for development. In the future, with the accelerated pace of modernization in my country and the gradual advancement of the construction industry, it will greatly drive the vigorous development of building intelligence. [0003] For multi-storey buildings or high-rise buildings, the security management system includes anti-theft alarm system, automatic...

AI Technical Summary

Problems solved by technology

[0003] For multi-storey buildings or high-rise buildings, the security management system includes anti-theft alarm system, automatic fire alarm system, computer room environment monitoring system, closed-circuit television monitoring system and building structure safety monitoring system. Each system operates independently and the servers are deployed separately. The investment is huge. The operating cost is high, and there is a lack of necessary linkage between the various systems, and the level of intelligence is low; the security system needs to select control boxes of different specifications according to the number of points connected, the type of protocol and the number of data lines, and there are air switches inside. , switching power supply, network controller, direct digital controller, magnetic latching relay, serial port module and terminal block, not only the wiring workload is large, but also the equipment box needs to occupy a large space, and the customization is poor; the equipment installation in the control box The tightness, large instantaneous current, insufficient cable diameter or flame retardancy may cause excessive temperature of the equipment, and may even cause serious accidents such as short circuit or fire; the communication protocols used by intelligent equipment are not the same, and the various subsystems of the security management system The system requires frequent design, which is cumbersome, and the compatibility of existing equipment is insufficient; most control boxes are not equipped with LCD display screens, and point status parameters cannot be queried; the alarm output currently requires an external sound and light alarm, SMS modem, telephone modem, printer, The investment is large, and the initial configuration workload is relatively large; most security management hosts rely on wired network communication and are configured with a single processor. Once the network is interrupted or the processor fails, the system will be paralyzed; when the existing security management host is working, it cannot The data transmission rate of each alarm input interface is collected, and polling at different frequencies cannot be realized; when multiple security management hosts are connected to the same LAN and work at the same time, the processor cannot intelligently allocate network bandwidth according to the number of points and polling frequency requirements , it is prone to slow data transmission rate of some security management hosts
