City Internet fire safety digital surveillance system design and implementation (1)

0 introduction

Fire as a modern urban security an integral part of the system, with the rapid development of the modern city has become increasingly shows its importance.

But the current market city building fire safety systems are mostly single, features simple alarm, alarm, and command, serious constraints on the building's fire safety protection, delayed combat rescue time. Through the various fire investigation of the causes of the accident and fire statistics, found mostly due to human factors causing fire information omitted, late reporting and alerting device not opening in a timely manner. To this end, the establishment of the digital city building fire safety systems, each building fire safety systems into an integrated network of great significance, network monitoring and management is also an inevitable trend of fire. The current urban fire work mainly to unit-based, stand-alone sui generis systems, this model in smaller cities or more suitable. However, with the expansion of the scale of the city, this decentralized system shows its limitations. First, the decentralized system is not easy centralized management. As a city fire managers must thoroughly each unit field fire protection work, leaky pipes out of control. Secondly, the information can not be timely feedback. For on-site inspection units, rectification cannot get information in a timely manner. Third, as the basic unit of fire, as hierarchy ragged, importance of different reasons, when disaster strikes or may not be able to discover that the spread of fire.

Realities require modern city fire must form a ubiquitous security network, it always watched every corner of the city, you can stay informed about the local scene, when a major exception occurs, immediately to the striking way to monitor reports.

At the same time it is also the repository for municipal fire protection status, you can query consisting of information, and record stores. The development of modern technology to this requirement provides full technical support. As Internet technology for the rapid development of the Internet and people's lives more and more closely linked. The Internet not only for people with a vast network of information resources, and become understood world window, and the Internet and existing work mode, give full play to the Internet quickly, information sharing, for improving the existing work efficiency enhanced functional management will play an important role.

1. system composition

Building cities Internet monitoring system is a system engineering.

As it relates to the various units of the city, the Fire Department and Internet technology provider, so it is a complex project. However once it revolve, bring social benefits is enormous, Figure 1 is the municipal fire network monitoring system diagram.

　　

As the Internet, the cornerstone of fire monitoring system is decentralized units and fire alarm monitoring room, it is fire information providers and beneficiaries.

Each unit is responsible for the information collection of fire, alarm system maintenance, and specific conditions of processing. This part is the most basic and most important. If this part of the alarm system is paralysed, information collection will talk about, let alone monitor monitoring. Only units of the alarm system is a real-time monitoring status, discover early fire risks, on the one hand you can promptly notify attendance for units, and on the other hand, even if the unit is on duty personnel negligence, but also to reflect the city monitor, the city's monitoring centre in a timely manner, so as not to mischief. This is in reality have important practical effects, can be said that this dual city fire insurance can prevent many fire danger, fire monitoring centres located in fire brigade, as fire before the last line of insurance, it is also very important. Because real life for various reasons not every organization will be able to fully implement the watch system, in this State one corner of the city is out of danger, once the danger often plague is inevitable. But if you build a city fire digital surveillance system, when on duty who found a exception, first notify local watch, but when the disaster has constantly upgraded to make the signs, notify the fire department rushed to the scene. In the usual here is the city's fire information resides, the historical situation in various sectors, focusing on sector information, information may be needed in a timely manner. As connection unit and city fire bridge between the monitoring center and the Internet generally will be the local telecom sector, with the popularization of modern networks and the ongoing technology upgrades such as broadband networks, optical fiber, the integrated information network, and information access will be increasingly difficult.
