The construction equipment can also send the operation status of the equipment through the dry contact signal to communicate with the construction equipment monitoring system.
For example, the monitoring equipment and application software provided by the building intelligent engineering contractor may be a multi vendor, multi operating platform, multi system and multi application oriented architecture.
The chiller, heat pump unit and boiler equipment can provide the communication interface card, communication protocol and interface software of the equipment to connect with the building equipment monitoring system by communication.
For example, the installation of detectors on indoor hanging flat roof should be coordinated and positioned with building decoration and electromechanical engineering construction.
The models and specifications of equipment and materials shall meet the design requirements and national standards, and the equipment interfaces of each system must match.
(5) Imported equipment shall be provided with quality certificate, test report, installation, use, maintenance instructions and other documents (Chinese text or attached with Chinese translation), as well as certificate of origin and commodity inspection certificate.
(2) Before construction, the process handover shall be well done, and the coordination with building structure, building decoration, building water supply and drainage, building electrical, heating, ventilation, air conditioning, elevator and other projects shall be well done.
(2) For the communication of interface mode between the building equipment monitoring system and large-scale building equipment such as power transformation and distribution equipment, generator set, chiller, heat pump unit, boiler and electricity, the communication protocol must be agreed in advance.
It mainly defines the supply scope of equipment and materials for building equipment monitoring system and electromechanical engineering.
2) Interface test documents shall meet the design requirements; Interface test documents shall include test link construction, test instruments, test methods, test contents and test result evaluation, etc.

General construction procedures of building intelligent engineering: construction preparation and construction drawing deepening → equipment and material procurement → pipeline laying → equipment Component installation → system commissioning → system commissioning → system testing → system acceptance.
For example, during construction, it is necessary to determine the installation position of the control valve, the opening of the pipeline and the installation of detection elements, the laying position of the line, and the manpower, equipment and responsibilities and obligations invested by the construction related parties in the commissioning process, which are important guarantees for the normal progress of the project.
(1) The selection of building intelligent equipment should determine the overall structure of the system according to the characteristics of project management, monitoring requirements and monitoring distribution, and then select equipment products.
For example, the building equipment monitoring system can share some data of other systems through TCP / TP communication protocol or RS232 interface to realize the control and linkage of each system.
For example, each system has a conventional monitoring point limit and monitoring distance limit supported.
The contractor of monitoring system engineering shall provide temperature, flow, differential pressure and pressure sensor, differential pressure on-off and other equipment and corresponding application software.
Construction drawing deepening understand the basic situation of the building, the location of construction equipment, control mode, technical requirements and other data from other construction drawings, and then deepen the construction drawing for the intelligent project.
Building intelligent system should adopt unified communication protocol in order to solve the problems of communication between equipment or systems.
3.
1) Interface technical documents shall comply with contract requirements; Interface technical documents shall include interface overview, interface block diagram, interface location, interface type and quantity, interface communication protocol, data flow direction, interface responsibility boundary, etc.
(3) Determine the installation position of electromechanical equipment and pipelines involved in the building equipment monitoring system, the pipeline laying, threading and wiring of the monitoring system, equipment commissioning and mutual cooperation mode.
The modules required for the corresponding floor can be set in the junction box for future maintenance and adjustment..
2.
If the building equipment monitoring system and the control system of large equipment have the same communication protocol and standard interface, they can communicate directly.
For example, when the air conditioning contractor provides air conditioning equipment, it shall also provide communication and interface meeting the monitoring and control requirements.
For equipment and materials that do not meet the conditions for on-site testing, factory testing can be required and a test report can be issued.
The key of building intelligent system is to solve the problems of interconnection and interoperability between systems.
When non-standard communication protocol is adopted for equipment control, the equipment contractor is required to provide data format, which is converted by the contractor of building equipment monitoring system.
(3) The functional performance of equipment, materials, interfaces and software used in building intelligent engineering shall be measured according to the corresponding current national standards.
Pipeline laying (1) the cables output from the machine room are laid to each floor through the weak current shaft.
Several junction boxes are set in the weak current shaft on each floor.
When the conventional limit is exceeded, some equipment products can be expanded by adding equipment, but the system investment will increase or the system performance will decline; Some equipment products may be powerless.
(2) Factors to be considered in the selection of building intelligent equipment: brand and production place of equipment products, application practice, supply channel and supply cycle; System scale and monitoring distance supported by equipment products; Network performance and standardization degree of equipment products.
Procurement and acceptance of equipment and materials (1) the division of equipment supply interface between the contractor of intelligent system and the contractor of monitored equipment shall be clear in the procurement of equipment and materials.
1.
Products with special requirements from both the supplier and the demander can be manufactured according to the contract or design requirements.
(1) Before construction, the procurement and installation scope of intelligent monitoring equipment and monitored equipment shall be clarified to avoid wrangling and affecting the project progress in the construction process.
(4) The quality inspection of equipment shall focus on safety, reliability, electromagnetic compatibility and other items.
They need to be clarified before construction to avoid mutual shirking of responsibilities in case of problems in the monitoring system project.
The determination of the implementation interface of building intelligent project in construction preparation is implemented in the whole process of construction drawing deepening, equipment procurement, project construction, system commissioning, system commissioning, system testing and completion acceptance.
