“Source Control”, the building control technology with China’s independent intellectual property rights, the control system based on PLC subverts the traditional DDC technical route, truly creates a comfortable and healthy indoor environment, and realizes a new height of energy conservation.
With the rapid development of China’s economy, super high-rise buildings continue to emerge, in order to achieve a balance point between comfortable environment, normal management and operation and efficient energy saving, it is inseparable from the building automation system.
MPS105-2302448 However, for a long time, China’s building automation technology and products have been monopolized by foreign enterprises for a long time, they provide the market not only large-scale standardized production of hardware, and the software is also standardized fixed, that is, the use of DDC(direct digital controller) method to control, to reduce the cost of building control. Since the 1990s, almost all large-scale high-rise office projects have adopted this controller, and DDC controllers once became the only choice for building control.
However, the building automatic control system with DDC controller as the core has highlighted its drawbacks in recent years: because the software has been solidified, it cannot be modified, and once there is a hardware or software problem, it is necessary to invite foreign brand engineers to the site to repair. High maintenance costs, long waiting period, and DDC controller does not have the openness and variability of software, so that when there is a problem in the building control system, domestic property companies often turn off the automatic operation of the control system and replace it with manual control.
There’s an automatic control system in place, but it’s a dummy. The DDC automatic control system that has been put into use often returns to manual control in 2 to 5 years, and only 7% of high-rise buildings achieve global optimization operation. This uncomfortable reality is becoming an increasingly common phenomenon.
This unhealthy market performance has caused more and more MPS105-2302448 concerns and concerns in the industry. Mr. Hu Baiju, who has been concerned about the development of building control industry for a long time, wrote a special article “Domestic goods should be self-improvement – Development and Prospects of China’s Building automatic control System”, in which he issued a striking exclamation: “Why does China not have its own building control technology?”
To change the situation of relying on people, we must have core technology. “Yuanbrand Automation”, as one of the forces that want to change the status quo of building automation, has carried out many years of thinking and practice on China’s building control technology. They start from the field of automatic control, search for the root, with the source of DDC – PLC(Programmable controller) to write building control system.
PLC technology in the field of industrial control has been very mature, MPS105-2302448 and has flexible programming ability, with the lack of DDC openness and variability, can be written according to the characteristics of the specific project control system, in order to achieve the best control effect, break the DDC building control system “does not have openness and variability” the deepest pain.
In 2009, the “Source brand automatic control” technology in the world’s greenest skyscraper – Guangzhou Zhujiang City building for the first time large-scale integrated application, the building since the operation not only indoor health environment first-class, but also per square meter of use area of the annual electricity consumption is only 86 KWH! The indoor air environment is first-class, the energy consumption is the lowest in Guangzhou, and the green Pearl River City is speaking with data.
At the end of 2019, the tallest building in Beijing, CITIC Tower (formerly known as China Zun), with a height of 528 meters, successfully passed the completion acceptance. As the Chinese model of super tall buildings, she has created eleven of the world’s best. The “Source Brand Automatic control” after ten years of research helps the building achieve the best in the control of indoor temperature, humidity, cleanliness, fresh air quality and other environmental indicators.
“Source brand automation”, this hardware reliable, software open, quality service of China’s building automation technology, from the people are not known, to the North, Guangzhou, Shenzhen and Hangzhou first-tier cities such as landmark buildings to achieve a successful demonstration, its success has changed the basic status quo of China’s building automatic control repeatedly failed.
