The "green" of "green building" does not refer to three-dimensional greening and rooftop gardens in the general sense but represents a concept or symbol that means the building is environmentally friendly and can make full use of the natural resources of the environment. A kind of building built under the condition of ecological balance can also be called as sustainable development building, ecological building, returning to nature building, energy saving and environmental protection building. There are six types of green building evaluation system indicators, divided into high-low Samsung, two stars and one star. Today, this article will give you a detailed explanation of the status quo of China's green building technology application research, the specific content see below. First, an overview of the concepts related to green buildings (A) the concept of green building Now, some construction companies name their green buildings and introduce some concepts of landscape architecture. In fact, this is a market speculation. In fact, this approach will make people misunderstood the meaning of green building. People will think that planting flowers and grass is a green building. In fact, The concept is wrong. Since green building is still a new thing in our country and most people do not know much about it, what is green building? Our country's Ministry of Construction currently defines green building as: "Green buildings are primarily designed to give people a healthy and comfortable environment and have some space for simple activities, while requiring architects to work in the entire building The use of resources, including energy conservation, water conservation and material saving, is realized within the life cycle of the object. Architects need to minimize the negative impact on the environment. This is a green building. (B) the characteristics of green buildings Green building mainly has the following characteristics: 1. The goal of green building is to reduce the consumption of building energy to a reasonable range. Therefore, in the process of construction, we must try our best to make use of a series of natural resources such as solar energy and wind energy and some renewable resources Therefore, making full use of energy-saving technologies can effectively prevent the enterprises from being polluted. In our survey, our survey shows that green buildings can save 70% -75% of energy compared with the old buildings in the past Consumption 2. The production of green buildings can effectively protect the environment and can better benefit our future generations. The most important thing is that we can use the land more reasonably and avoid the waste of land. In the process of construction, we use non-polluting and environment-friendly materials , At the same time the construction of domestic waste in a reasonable digestion, so that you can form and the biological chain of the same virtuous circle. 3. Green buildings in our country now show a strong geographical, because our country's green buildings have been emphasizing the use of our local raw materials, not only that, but also to respect the human and natural conditions in various places, not to undermine the environment Therefore, the style of green building should be localized throughout the entire building. Therefore, according to this standard, the building we produce is a healthy living environment, not the same as in the past Commercialized products, in the past, standardized architecture so that our architectural styles around the country are more or less the same. Green building not only has a healthy and rational structure, such as orientation, shape, etc. More importantly, houses built according to this green building standard should have good lighting, good ventilation, and comfortable natural Environment, to be able to climate change will be automatically adjusted. Application and Development of Green Building Technology in China Building energy efficiency in our country started from the 80s of last century. With the rise of our country's real estate industry, the concept of green building has gradually become familiar to everyone. According to statistics, there are more than 740 green building evaluation marking projects in China The total area of ​​nearly 7600 square meters. Green building technology is slow in our country at present. The main reasons are as follows: First, many people may not fully understand the essential meaning of green building. One-sidedly think of green building as just around and inside buildings Greening. The green building industry is currently undergoing rapid improvements. Today's Green Building It is a long-term benefit building. We know from its long-term cost that in the long term it is a truly energy-efficient building. Now it's part of it Fully draws on our country's traditional architectural design, the other part of our country's traditional architectural art innovation, therefore, it not only draws on our country's traditional building energy efficiency, but more importantly, reflects the local elements in the construction materials and Construction aspects of independent innovation. Second, the differences between green buildings will be relatively large. At present, most of the research focuses on first-tier cities. However, there is a lack of systematic research on township and village enterprises. Most of the scholars started from the general architectural design when they studied. System research of green building design. In our country, the architect community now publishes a lot of articles on green building, but many articles are now stuck in the theoretical framework of green building design, design principles and some research and theoretical knowledge of foreign architecture. However, these researches all lack our country Therefore, there are really no reference examples for the architects in our country. Therefore, some architects lack uniform consideration in their work. In many cases, only after the construction is completed Consideration of greening, energy saving, etc. is applied. If we only consider energy saving and greening around, this will not improve the overall performance of the building. Problems in the Development of Green Building Technology in China At present, the green building technology in our country is still not widely used now, and many problems still exist in many aspects: 1. The whole society environmental protection, energy conservation awareness is not strong Our country put forward the standard of green building, indicating that the government has enough recognition, but from the perspective of the entire society, the awareness of green is not very strong, compared with the developed countries in the west, some of the construction industry for energy saving The importance of platoon is not yet given special attention. There is still a big gap between this strong awareness of environmental crisis and western countries. 2. The level of building industrialization needs to be improved
The sensor of the loader is divided into: temperature sensor, fuel sensor, Cummins Oil Pressure Sensor 4921517 4921497, Liugong Water in fuel sensor 08C4388, speed sensor, Pressure Sensor Switch 30B1067, pressure switch, these sensor components can at any time monitor the engine and loader each part of the oil pressure, hydraulic oil pressure, electrical, fuel, valve phase and other operating information, to facilitate the driver to control the vehicle.
The role of the loader pressure sensor
Loader pressure sensor is the most widely used sensor, it is the detection of gas, liquid, solid and other substances between the influence of the energy of the general name. There are many kinds of high sensitive sensors. The traditional measurement method is to use the deformation and displacement of elastic elements to express the maintenance of the EFI engine, but its volume is large, clumsy, and the output is nonlinear. With the growth of microelectronics technology, the application of semiconductor materials piezoresistive effect and excellent elasticity, developed semiconductor high sensitive sensor, the important silicon piezoresistive and capacitive two, they have small size, light weight, high sensitivity advantages, is widely used semiconductor force sensor. When stress is applied to a crystal of a semiconductor, its resistivity changes. The relationship between conductor resistivity change and stress is called semiconductor piezoresistive effect, and the mechanical quantity sensor made of this effect is called piezoresistive force sensor. It has two types. One is the sensor made of semiconductor strain gauge pasted on the elastic element, which is called pasted piezoresistive sensor. The other is the diffusion resistance made of integrated circuit technology on the semiconductor material substrate, so that the strain gauge and silicon substrate form the same whole sensor, called the diffusion piezoresistive sensor. High sensitivity, high precision, small volume, light weight, high working frequency, simple structure, reliable work, long life and so on.
