安防监控工程系统施工中的隐蔽工程，主要是埋地管线等的施工。为了保证施工质量，在施工过程中，对于地面沟槽的开挖、管线的埋设等，都必须严格按照设计施工图纸进行，确保沟槽开挖的深度、标高、方向等均符合设计要求，所用到的管线能够满足施工的相关标准。在对管线进行安装时，要做好施工控制，避免出现接头外露或者线路扭曲等质量问题，同时确保线缆总截面面积在线管截面面积的 40%以上，并在管口位置设置防护圈，避免线缆在管道中的随意移动。如果是对墙内管线进行敷设，需要充分考虑墙体的美观性和牢固性，将管线敷设在非承重墙中，同时尽量缩短管线距离，避免管线的频繁弯曲。另外，要做好管线的接地施工和搭接施工，将墙面与管路的净距离控制在 15mm 以上。 安防监控系统的管线，应该尽量与其他管道一起，布置在吊顶内，并对管线进行处理，避免出现杂乱交叉的现象，以保证施工质量。
Building weak current engineering and security monitoring engineering system
In the application of electric power in security monitoring engineering, according to the power transmission strength, it can be divided into two categories: weak current and strong current. Generally speaking, the weak electricity in the building mainly includes the safety voltage grade stipulated by the state, the control voltage and other low voltage electric energy, such as the control power supply, emergency lighting standby power supply, and the information source containing voice, image and data, such as telephone, television, computer information. In the field of AI intelligent building, the application degree of weak current technology directly determines the intellectualization level of the building. The project of weak current project includes telephone, broadband, catv, fire alarm to wait, technical content is good, construction is complex, and construction cycle is longer, need the sufficient attention of construction personnel.
Security monitoring engineering system, mainly to maintain social public safety, for the purpose of the use of security products and other related products of intrusion alarm systems, video security monitoring system, such as explosion-proof safety inspection system, or is made up of these systems or in building weak current engineering, applied to security system construction, and needs to take corresponding measures, in order to ensure the effective role in the security system.
1. Construction of security monitoring project
The construction of security system includes the following two aspects:
(1) concealed construction
Concealed works in the construction of security monitoring engineering system are mainly the construction of buried pipelines. In order to ensure the construction quality, during the construction process, the excavation of the ground trench and the burial of pipelines must be carried out in strict accordance with the design and construction drawings, so as to ensure that the depth, elevation and direction of trench excavation are in line with the design requirements, and the pipelines used can meet the relevant construction standards. During the installation of pipelines, construction control should be done to avoid joint exposure or line distortion and other quality problems. Meanwhile, more than 40% of the total section area of cables should be ensured, and protective rings should be set at the position of the pipe mouth to avoid the random movement of cables in the pipeline. If laying the pipelines inside the wall, the aesthetics and firmness of the wall should be fully considered, the pipelines should be laid in the non-load-bearing wall, and the distance of pipelines should be shortened as far as possible to avoid frequent bending of pipelines. In addition, grounding and lapping of pipelines should be done well, and the net distance between walls and pipelines should be controlled above 15mm. Security monitoring system pipeline, should as far as possible with other pipelines together, arranged in the ceiling, and the pipeline to deal with, avoid the phenomenon of intersections in disorder, in order to ensure the quality of construction.
(2) installation of security monitoring equipment
After the completion of civil engineering construction, the installation and construction of security monitoring equipment can be carried out. Before the installation of the equipment, it is necessary to conduct a comprehensive inspection to ensure that the equipment is in normal working condition. Then, according to the characteristics and functions of the equipment, the installation location should be reasonably selected. Take the camera as an example, under normal circumstances, the camera is installed fixed on the ground bracket, and the role of part of the camera is to patrol a larger range, should be installed on the head, at the same time to ensure that the field of vision is open, avoid communication lines and other shielding to the camera. At the same time, the console and cabinet should be installed in accordance with relevant specifications and design requirements to ensure the accuracy and solidity of installation, and facilitate management and maintenance to ensure the normal play of security system functions.
2. Construction management and acceptance
The construction of security monitoring project involves many majors, and its content is also very complex. Therefore, before the construction, the construction personnel should be fully familiar with the construction process and construction process, understand the key and difficult points of the construction, and do a good job in the coordination between the majors.
At the same time, in the process of construction, should often check the construction drawings, timely find the existing problems, reduce the rework phenomenon. After the completion of the construction, the acceptance of the project should be done, and the construction quality of the project should be controlled to ensure the reliability and practicability of the security system. Once the equipment quality problems or performance problems are found in the acceptance, timely analysis and treatment should be carried out to eliminate the potential quality problems in the security system as far as possible.
In a word, the application of security monitoring system in building weak current project can effectively improve the building's intelligence level and automation level, and ensure the use of the building safety. For engineering design and construction personnel, to pay full attention to, do a good job of security system equipment selection, testing and installation construction, do a good job of security system management and acceptance, to ensure the construction quality of the project, to provide users with a safer and more comfortable working and living environment.
