What aspects does weak current maintenance include?

Weak current is mainly about control loop and system maintenance. The specific work depends on the type of enterprise you work for. Mainly after-sales technical maintenance, mainly engineering installation, debugging and transportation guarantee. 1, organize the blue prints.the design of weak current to discuss and review the construction design and construction scheme; 2. Prepare the technical specification documents for strong and weak electricity bidding, and be responsible for summarizing the review opinions of various departments; 3. Coordinate and review the preliminary weak current construction scheme and construction drawing design, and provide technical support for weak current engineering or equipment bidding; 4. Manage the strong and weak current projects at the project site, including the control and management of progress, quality, safety, investment and completion delivery; 9. Participate in the review of completion data and the preliminary inspection and completion acceptance of the unit project. 5. Background music system (sometimes with fire protection system * * *, * it should be noted that fire protection is an independent weak current system) 6. Communication system (voice exchange or private branch exchange, which Party A requires operators to provide for most projects) 7. Fire fighting system (fire smoke exhaust, alarm, water spraying and other systems, heptafluoropropane gas fire fighting may occur in the engineering room) 8. CATV system (CATV wiring system involving two-way transmission in the building, satellite reception and front-end modulation may occur) 9. Conference system (some buildings will have large conference rooms, which need audio and video design) * 13, three-meter reading system (mainly used for remote meter reading in residential buildings, and many office buildings are also in use at present) * 14, building intercom system (visible and invisible, this system generally only appears in residential projects. Less in office buildings) * 15, weak current pipeline system (including weak current pipeline and bridge) * 17, property management system (appearing in office buildings or residential areas for property management, generally integrated into office automation system) * 19, video-on-demand system (generally as an optional part of hotel projects, it also exists in individual residential areas and parks). Weak current engineering includes TV engineering, communication engineering, fire engineering, security engineering, image engineering, etc. And the integrated wiring project for the above projects. Intelligent weak current projects: automatic control system of building equipment (water supply and drainage, power distribution, heating and ventilation), automatic fire alarm and fire control system, safety monitoring system (access control system, parking lot control system), satellite TV and broadcasting system, intelligent system of residential quarters, etc.
