【 Weak current College 】 go; determine floors control system in the project's success or failure of several factors

Now, a lot of party a while in a project are determined to do the building control, but many stakeholders do not know the control to be able to get on the floor of the building benefits from what, do not know the importance of property control, it is not clear what kind of property on the control system, mostly in response to the State energy conservation Office checks, and face problems as regards the upstairs control after things, such as: how to use a good floor control and how to maintain the interests of building control and how to improve management efficiency, receive benefits? many people these they will be ignored.
Then, on the floor-control system, in order to face the problem or stomach problems?

If it is to solve the problem, on the face of the building automation system, the building is the intelligent building, can meet the requirements of the national energy conservation and emission reduction, select floor control is easy, just look for the brand, even if later, you can blame to the well-known brands like: "so well-known brands are out of the question of building control, instead I choose the wrong problem", you can easily take over the losses of the national or enterprise with millions of investment, building control of meaning is not implemented.

Solve problems, stomach is true to select the right building control system, with a good building control system, so that the building control system can really improve the building's management, protection of equipment investment and achieve energy-saving purposes, I believe that all the stakeholders as to building control, all want to be able to achieve the above objectives, we focus on the building control industry for 10 years, participated in many projects, they hear a project looking at more, very few stairs control but do not want to use a good customer, rarely sold the building control system after the hope project failed companies, but it is undeniable that a lot of building up the stairs after the control has no use, out of this or that problem, didn't used to have many causes, and each project's needs and building control content are not the same,

So, how do you select the right floor control, with good building control? decide floor control system in the building on the success factors in the end what?

I. clear requirements:

Project from the project, the project party should explicitly demand — upstairs control system to let the building reached what features? need invest? plan within a few years back, these requirements should not be entrusted to the Institute to do, but these requirements specific to the Design Institute to design. Floor control system throughout the weak electricity system is a special one because the other systems have very specific functions, such as security systems to protect the personal and property security, network, is the phone and network traffic bridge, fire is fire prevention and building control, and so on, the function is contains the following three basic functions:

1. easy building of electromechanical equipment, protective devices and equipment fault early warning capabilities: in all buildings, the number and types of numerous mechanical and electrical equipment and distribution throughout various parts of the building, if there is no floor control system will these devices a unified centralized monitoring up, it will take many human 24 hours time monitoring, property management, resulting in great inconvenience, in addition, when the equipment is provided, the floor control will fail device location and fault content to watch, and building control system fault early warning mechanism will be established, building control be cumulative statistical device operating time, and in attaining the equipment normal life span, will issue a replacement information before they happen.

2, environmental regulation and control: in various types of construction, environmental requirements are not the same, in Office buildings, shopping malls, office buildings and other architectural types, environmental requirements are met and comfortable, in the environment requires high places and buildings, the dust concentration, air quality, temperature and humidity, air pressure, etc. will make very high demands on these are not achieved by virtue of manpower, and building control system to select the correct operating mode and correct sensing device, capable of precise control on the environment.

3. saving energy: renewable energy is not the State in the "eleventh five-year plan" explicitly put forward on building energy-saving, power saving topic is cliche, large power consumption of the building in the central air conditioning and lighting, no doubt, building control systems on both power-saving efficacy of large is very obvious, but, many buildings in the upstairs accused found did not achieve the purpose of saving power or electricity is rare, this is why? their reasons about the following aspects "

L central air-conditioning system design is not reasonable and selection is not correct, when the air conditioning system of the maximum load is not for building on refrigeration or heating needs, the air conditioning equipment every day is full-load operation, even on the floor, control, as the purpose of saving power;

L air conditioning systems in all aspects of the poor converge, air-conditioning system, including the host, all kinds of pumps, air handling units, air supply unit, blower, etc. equipment, many buildings in order to save money, but the air conditioning system part of the control instead of the entire air conditioning system into a whole control, creating a control, building control cannot correct analysis and consolidation of power management for each device, allowing the building control functions cannot play;

L air conditioning system in the frequency range is too small, chilled water system of transportation by water pump, water pump power consumption is very large, energy-saving pump with variable frequency is a very effective means, but because of the frequency converter of debugging and building control with debug up technically difficult, making some manufacturers willfully evading, and some projects are not aware of the frequency of the inverter and the price is more expensive, making the frequency in the project;

L lighting control, maximum will be building lighting control, is also an important means of saving power.

Project party expressly the demand, and will demand a firm into every step of the future is to protect the floor control successful fundamental first step.

Second, design coordination and liaison

Clear the demand, the project will be handed over to the design side needs to be designed, although most of the Design Institute has floor control designers, but to be honest they andNot professional, most of the time, designers will design, control of deepening allow ELV company to do, and most of the ELV company will give them the familiar or cooperation of manufacturers to make and influence manufacturers in accordance with their budgetary and ideas, to deepen the ultimate yilaierqu designed and implemented, will and earliest project requirements have had a deviation from the normal function of the building, but at this point because the project has started and the project has also started part subject to the Contracting Parties that want to back up the original demand was already too late, if forced to change can only increase investment, so that the project should control from the implementation of floor should be directly after the demand and vendor communication and design party three parties determine floors-controlled content and budget, from the project and design common supervision of several manufacturers at the same time deepening design, eventually choose the one that best project, best price/performance of manufacturers to cooperate in the implementation, can be taken over by the ELV-party to monitor the implementation and checkout, you can also directly by the project participants will be building control system separate from the power of direct supervision and settlement, both advantages and disadvantages.

III. construction coordination

Many building control system in the application project does not have a large reason normally depends on the construction of the complex, there are two factors:

1, construction management factors: now in most projects, building control system equipment, technical guidance, programming, debugging is available from the manufacturer, the installation and wiring is done by ELV, floor, the prosecution was belonging to ELV, manufacturers can give undertook to provide strong technical support, ELV party is properly understood manufacturer's technology, this is a problem; second, building control system in implementation need and many trades with: air conditioning, water, strong power, construction, light, decorate, etc, and these types of work and the total package belonging to another party, which tie in with the ELV party to coordinate, as long as there is no clear on the one hand, it will cause a building control system failure;

2. Fund management factors: building the prosecution from belonging to the ELV, ELV party and from belonging to the construction contracting party, the Contracting Party from belonging to the project, this is the most basic structure, therefore, even if the project will fund have already paid, but after so many subcontracting deduction and delay, the arrival floor, the prosecution in the hands of the funds will be significantly delayed and reduce the prosecution's failure to make timely and quantity to the capital, certainly not on schedule or reduce the final project amount, is affected by the loss of, or the project parties resulted in a building with no success.

4 project usessecurity and maintenance

Project was completed and put into use, building control systems generally have 1 ~ 2 years of free maintenance, but this time, no matter which vendor's equipment and systems are completely new, so in 1 ~ 2 years basically does not produce too much problem, but after this period of free maintenance period, no one can control of these devices, many manufacturers will not be at the core of the system such as software programming and use, etc. to teach project party project party project officer is not possible to fully understand how so many devices and systems and the maintenance and management, the device starts to slowly decay, overload, system maintenance, and ultimately no standstill is pervasive, of course, free maintenance period expires, the manufacturers and equipment providers have to find a project to provide paid maintenance for the system, but the General costs are more expensive, the project also unacceptable because of financial considerations, only their own maintenance by engineering staff reluctantly, but generally not achieve systems and equipment in the normal life span, but accepted the paid services, annual expenditure will be huge, building control can save energy and all consumption to this part of the manufacturer, this is the floor control system in use after success. The solution is: in the House, accused and free maintenance period, the project should require manufacturers to open programming tutorials and training out one or several of the project staff, free maintenance period is over, the project will no longer be any restraint and manufacturers can solve problems on their own.
