Abstract: From Data Acquisition, Network Transmission, The Technique Analyzes 3 Aspects Of Middle Management Automated

Abstract: From information acquisition, network transmission, the procedure analyzes three areas of Center management automatic fire alarm monitoring and manage network Technological innovation Software position, and further the long term of automated fire alarm monitoring and management network technologies developments. Major words: fire Probe; Alarm monitoring; networkingWith the progress of urban construction, fire hazards boosting probability of main fire upward trend. Presently installed in the constructing fire detection and fire alarm program installations, fire alarm within the early detection and prevention play a significant position within the fire, but while in the process of exposing the true use of the product good quality, tools management, alarm dealing with and also other concerns is now additional evident, serious influence on the fire detection and alarm products, the ordinary capabilities. Modern day Talk And network transmission technology produced around the foundation of automated fire alarm network monitoring technologies, can make certain that the fire detection and alarm methods and fire security facilities running and play its due function in fire detection and alarm technique via the transmission tools running information and alarm information and facts for Fire manage and fire rescue departments to provide powerful help to realize shorter warning time, speedy and exact fire fighting and rescue, increase the general amount of catastrophe prevention and mitigation technologies. 1 automated fire alarm network monitoring technological know-how for software statusAutomatic fire alarm network monitoring technological know-how in foreign nations and regions have applied before, our software of this technological know-how began inside the mid-nineties of last century, but fast advancement in recent years. Currently, there are plenty of investigation institutes and makers committed to R & D areas for the characteristics of our fire automatic fire alarm monitoring and manage network technologies and related products, established in some cities Fire Alarm Monitoring network system, fire management and fire rescue to play an essential part. Fire alarm monitoring network generally fire alarm monitoring terminal (also known as fire transmission tools, referred to as monitoring terminal) communications network alarm monitoring, alarm monitoring center of three parts. The automated fire alarm network monitoring technologies, info acquisition from the device, network transmission, and Program Center management analysis and discussion of three factors. one.one Tools Information Acquisition Manage terminal set inside the fire security in the general focus of the unit and user units connected to fire detection and alarm techniques, fire detection and alarm programs about the products running and working status in real-time monitoring, as a result of information collection, will run the data and alarm data transmitted through the communication network alarm monitoring to fire alarm monitoring middle. Current monitoring data collection terminal software form You will discover analog monitoring and serial info communication in two ways. Currently used in fire detection and alarm methods are generally used to indicate devices with working automatic fire fighting tools or manage the output contacts. Handle terminal is the utilization of these passive or active output contacts, by detecting current, voltage, or off from the method implementation of fire detection and alarm tools operation and alarm standing monitoring. Analog monitor mode because of its simple and effective, easy to implement, is presently widely used. The use of such methods, fire detection and alarm techniques can only understand a simple device working position (such as operating, fault, alarm, etc.) can not meet the current fire department's fire security regulatory requirements. Serial info communication (RS-232, RS-422, RS-485, etc.) for data collection can be a good way to make up for the shortcomings of analog monitor. Fire detection and alarm procedure using the external serial data communication interface, manage terminal can be connected with exchange of information, fire detection and alarm devices by analyzing the data communication protocol, can be obtained from the output data is a lot more accurate monitoring devices, alarm site, alarm type, technique position, fault facts, work records as well as other information. To determine the authenticity on the details fire, police positions to understand and master the specific operation of devices, a great convenience to shorten the warning time from the realization of precise fire fighting quickly deliver a reliable technical assist. However, fire detection and alarm procedure tools producers a large variety of models, their external information communication protocol there is no uniform standards, communication protocols to monitor the terminal complex applications for info collection serial communication has brought great inconvenience, which is a serious constraint automatic fire alarm monitoring and manage network methods promote the utilization of difficult problems.
