1、精选优质文档-倾情为你奉上毕业设计说明书外文文献原文及译文信息与通信工程学生姓名: 学号: 通信工程系 别: 王晨光专 业: 指导教师: 2009年 6 月 The Fire Auto-alarm System DesignAlong with the our country economic development rapid development, the lives of the people level unceasing enhancement, the city uses to be day by day anxious, urges the building to face t
2、he direction is developing. This kind of high level civil construction repair needed materials and the way also more hasten the diversification, and along with uses electricity the load and coal gas consumption quantity enlarging, proposed to the fire auto-alarm system design is higher, a stricter r
3、equest. In order to guarantee the people life and property the security, the fire auto-alarm system design has become in the high level civil construction design one of most important design contents. Presently based on the author fire of auto-alarm system design overseeing work in the high level ci
4、vil building experience, proposed in present national related standard and standard unclear true detail shallow opinion, by for the colleagues to discuss and to point out mistakes.First, design basisThe fire auto-alarm system design is a specialized very strong technology work, at the same time also
5、 has the very strong policy-type. Therefore, first should be clear about the following design basis:1st, must grasp the architectural design fire protection standard, the system design standard, the equipment manufacture standard, the installment construction approval standard and the administration
6、 laws and regulations and so on five big aspects fire laws and regulations, and in practical understanding present country related standard and standard positive word: Must, be supposed, to be suitable, may and the reverse side word: Strictly prohibits, should not, not have, not to be suitable the m
7、eaning.2nd, must aim at high level civil building function, use and the protection object fire protection rank, earnestly carries out the present national related standard and the standard, earnestly treats the public security fire prevention surveillance department the examination and approval opin
8、ion.Second, fire auto-alarm system equipment establishmentFire detector establishmentOpens wide either the seal or the stair hall should alone divide the search coverage, and each 2 3 establish a fire detector.The first room (including guards against in front of smoke stair hall in front of room, fi
9、re elevator room, fire elevator with guards against the front room which smoke stair hall comes in handy) and the aisle should distinguish alone to divide the search coverage, specially front the room and the lift well, the scattered stair hall and the aisle are interlinked, has time the fire haze t
10、o be easier to gather or to flow, is the personnel disperses which saves goal with the fire prevention, therefore should install the fire detector. Regarding common elevator in front of room although is not the personnel disperses , but this front room and the lift well are interlinked, has time the
11、 fire haze to be also easy to gather or to flow, suitably alone divides the search coverage and installs the fire detector.The electric cable shaft therefore is easy to form pulls out the smoke inflammation the channel; Has when the fire the fire intensity not easily extends along the electric cable
12、 burns, for this, the high level civil construction design fire protection standard and the civil construction electricity design standard separately proposes the detailed specific stipulation in the construction and in the electric wire or on the electric cable shaping. But considered implements sp
13、ecifically the difficulty and the present situation, the electric cable shaft installs the fire detector is extremely essential, and coordinates the shaft the fire protection separation request, each 2 3 or each level installs.The elevator machine room should install the fire detector, its elevator
14、is the important vertical transportation vehicle; Its two elevator machine room has has the fire risk; Its three lift well existence essential opens the hole, like the level gate opens between the hole, the air vent, the between permanence opens the hole with the elevator machine room or the pulley
15、and so on; Its four when has the fire, the lift well often becomes the fire intensity spread the channel, is easy to threaten the elevator machine room the facility. Therefore, the elevator machine room establishes the fire detector is necessary, crown of also suitable establishment fire detector li
16、ft well.2nd, the manual fire reports to the police the button establishment(Including guards against in front of smoke stair hall in view of various floors front room in front of room, fire elevator room, fire elevator with guards against which smoke stair hall to come in handy the front room) is ha
17、s when the fire the personnel to disperse which saves goal with fire prevention, should report to the police the button first choice spot as the establishment manual fire. In addition, the room also should establish the manual fire to the common elevator in front of to report to the police the butto
18、n.In the public active place (including hall, hall, dining room, multi-purpose hall and so on) and the main thoroughfare and so on place, the personnel very is all centralized, and mainly disperses the channel. Therefore should report to the police the button in these public active places main acces
19、s establishment manual fires; The manual fire establishes which in the main thoroughfare reports to the police the button to guarantee to a manual fire which most is close to reports to the police the button distance from a fire protection district any position not to be supposed to be bigger than 3
20、0 meters.3rd, the fire emergency broadcasts the speaker the establishmentThe aisle, the hall, the dining room and so on the public place personnel very are all centralized, and mainly disperses the channel. Therefore should press in these public places to a recent speaker distance is not bigger than
