This is also an important guarantee for the safe use of buildings and plays a role for various scientific and technological systems and auxiliary equipment. The role of escort.
How to do a good job of intelligent construction weak construction technology and quality management?
Therefore, before implementing the intelligent construction weak current project, we must strictly abide by the three elements of weak current system design, product technical standards, construction quality management and project quality management, and closely follow the above three factors to implement and manage the intelligent project to ensure Intelligent buildings can operate safely, efficiently, comfortably, and economically.
Prerequisites for Construction of Intelligent Building Weak Electricity Project
1) Overall design plan for weak current engineering system. The first step is to conduct in-depth analysis of the functional requirements for building use, conduct detailed technical discussions with technical personnel, master the design criteria of the project and the functional orientation of the system, and determine the overall from the consideration of the comprehensive factors of applicability, advancement, and economy. Design.
2) The choice of a premium system integrator (primary contractor). At present, the operation mode of the intelligent building weak current project in China is basically coordinated, managed and controlled by the system integrator or the owner, among which the selection system integrator accounts for the main part. Therefore, choosing a competent system integrator is the key to the success or failure of the entire weak current project, because it is an organic "integration" of technical implementation capabilities, project quality management, and coordination of organizational capabilities.
3) System maintenance and management of weak current projects. The normal operation after the implementation of the weak current project is a sign of the successful implementation of the project, but the safety, efficiency, comfort, and economy are the ultimate goals of the intelligent construction weak current project. Therefore, professional operation training for building management personnel is also required during project acceptance. Enhance system maintenance and management levels, and ongoing system maintenance and management are the basic guarantees for achieving the ultimate goal of intelligent buildings.
Technical Management Points of Intelligent Building Weak Electricity Engineering
1) Technical management of weak current engineering interface. In the early stage of the project, it needs to be determined according to the requirements of technical design and the terms of the contract:
1 Engineering interface between each system in the weak current and between each subsystem and the electromechanical equipment, civil engineering and decoration major;
2 Project scope and responsibility interface between product suppliers, work contractors and construction units;
3 Modify, adjust and reconfirm the above mentioned interface during the implementation process. This is one of the key difficulties in technical management in weak current projects. Before construction, review and confirm the drawings, materials, technical process and construction design mentioned above to ensure that the equipment list, monitoring point table and construction drawing in the contract are consistent to ensure the integrity of the system on the hardware equipment. And meet the requirements of various technical parameters, so as to ensure the duration, quality and reduce rework.
2) Construction management coordinated by various subsystems. Weak electricity engineering is a cooperative job that requires the professional close cooperation and coordination of various subsystems. Valves, water pipe temperature, sensors, flowmeters and flow switches and their installation, hole location, boss welding, and the coordination of dampers and actuators must all be coordinated with the corresponding work. Therefore, after each type of work is completed, registration of construction records must be carried out to form a complete set of engineering technical files, and project engineering acceptance should be carried out according to the acceptance criteria of the type of work and design drawings.
The main contents of the acceptance of intelligent building weak current project
At present, there is no standard completion acceptance system for intelligent building weak current projects in the country, but the acceptance standards for various localities have been gradually introduced. Shanghai Municipality issued the "Intelligent Building Construction and Acceptance Specifications (DG/TJ08-601-2001)" as the current acceptance criteria for weak current projects, and strict implementation of this specification is required in the future. This specification contains six subsystem acceptance criteria for smart building weak current projects:
1) Acceptance of electrical wiring and grounding systems. The detailed provisions are made on the common parts of laying and grounding systems involved in the sub-systems of weak current projects. For example, different systems, different voltages, different currents of the line tube sub-slots, in charge of laying; pipe and pipe, the connection between the pipe and the box; pressure ring, lightning down lead, lightning protection welding quality; strong, weak The construction safety of the system grounding line and other types of work are the basis for ensuring the safe operation of the weak current system. Each site must be carefully inspected to ensure construction quality. Acceptance should be carried out in accordance with the corresponding acceptance criteria. If the subsystem has special requirements, then make corresponding provisions.
2) Acceptance of construction equipment monitoring system. It is the centralized monitoring, control and management of the application equipment in the building, and detailed provisions for the commissioning and acceptance of monitoring system equipment, input equipment, and output equipment.
