The IDA system is a new product that Sinco has put on the market in recent years. IDA is an abbreviation for Intelligent Data Collection. The main components of the system are: sensors, multi-channel modules, interface repeaters, terminal boxes, I/R modules, power supplies, personal computers, sensing cables, buses, various lightning protectors, bus power controllers, overvoltages Protector, manual reading adapter and portable reading display, etc. The multi-channel module converts the sensor signal into a digital form and transmits it to the personal computer on site via the IDA bus. The PC will convert the data obtained from the engineering unit and save it to a floppy disk. If necessary, the PC can also analyze and compare the input data to preset alarm limits and issue alarms. Data can be printed, displayed, and can be repeatedly returned from the front PC to the rear PC for many times. The front PC is used for data recording and the rear is used for data analysis, and the data is transmitted by modem or floppy disk. The rear PC is responsible for data archiving, data analysis, drawing and report generation of the database. The Tennessee Engineering Administration (TVA) in the United States adopted IDAS in the monitoring of the Fontena Dam. The system works well and can also be used for the monitoring of landslides and tailings dams.

This year's Spring Festival, the snowstorm in the south is one of the topics of common concern. Faced with such a severe snowstorm situation, the landscape community also considered this incident. For China's landscape thinking, China's landscape environment, we need further integration.
Due to snowstorms in several provinces and cities in the south, on February 2, the General Office of the State Council issued an urgent notice to explicitly adopt coal-based electricity, electricity-specific, orderly use of electricity, and energy-saving measures to strictly control unreasonable electricity use. Strictly control the use of electricity for landscape lighting, limit the use of electricity in entertainment venues, and eliminate wasteful phenomena such as “lighting†projects. According to reports, Shanghai has closed all landscape lights to save energy and protect electricity. Beijing's entertainment venues (such as karaoke bars) have received notices of power cuts (February 3, "Beijing News").
In the face of natural disasters, the introduction of this emergency measure is naturally necessary. However, due to the frequent occurrence of the word "landscape" in the report, it reminds me of the work of the French thought home Guy Ernest Dobord "Landscape Society". As the founder of Situationist International, one of the most important things that Debord did in his life was to use "landscape" as the core concept to critically analyze the phenomena of Western consumer society. Debord is also worried about the threat posed by over-exploitation of resources. He said in an ironic tone: "Marine pollution and the destruction of the equatorial rainforest threaten the supply of oxygen; the Earth's ozone layer is threatened by industrial growth; nuclear radiation is irreversibly accumulating. The only conclusion that the landscape gives is that all of this The phenomenon is irrelevant.†Why is this happening? Debord’s answer is that people have formed a landscape thinking.
Although China has not fully entered the landscape society, the landscape thinking seems to have taken shape. For example, in order to show our boldness and spirit, we have built many iconic grand buildings; in order to make these buildings more landscape-like, a variety of landscape lights will slam. This kind of building is awkward during the day, either dark or white, and there is nothing to see, but in the evening, all of them become radiant and brilliant. Recalling the 1950s, the poet Liu faced the night of Shanghai and sang a song: "The canyon of lights, the river of lights, the mountains of lights / six million people wrote a magnificent poem / vertical and horizontal streets are poems / lights It is a punctuation." This kind of rhetoric seems to have predicted the direction of the landscape lights. If we can’t move today, it’s a bright light, maybe it’s a glorious tradition of the Lamp Hill.
But a snowstorm made us think of the exhaustion of the oil, and let us realize that the lamp was originally powered, and the electricity was originally made of coal. If the coal is not transported, it will not be sent out; if the electric hair does not come out, it will not light up. This kind of truth is actually very simple, but we usually don't think about it; it is only in an extraordinary period that we can think of common sense. Of course, we are still thinking about how to transport coal. In less than a very special period, we still can't think of how to use coal. More than a decade ago, for research, I used to enter the underground tunnel of a large coal mine in Shanxi. They told me at the time that the coal mine did not have much life expectancy because the coal was dug up. A few years later, the coal mine was shut down and the workers went to other places.
The reason why I raised this question is because for a long time, saving has always been our traditional virtue, but in recent years, saving guilt and spending rationality is becoming our main idea. Since we want to consume and even spend luxury, we need to develop more resources. The more resources we consume, the worse our ecological environment becomes. The worse the environment, the faster the pace of global warming; the faster the warming, the snowstorm The chances are probably more. The snowstorm is said to have been in the past 50 years, and it will not be known after three or five times. As early as more than 100 years ago, Engels said: "We should not be too fascinated by our human victory in nature. For every such victory, nature has retaliated against us." When we slammed the mountains to reclaim the dam When we say this, we can not believe it. But the problem is that we can not believe, but there is no way to stop the natural retaliation against us. Once retaliated, our “lighting project†immediately became dim, and the landscape society we are about to start will become extremely fragile.
I think that although the snowstorm is fierce, it is not terrible. The horrible thing is the greed that people are gradually expanding, and the social atmosphere of over-consumption. Therefore, in this extraordinary period, although “saving electricity†has finally been shouted out, after all the calm, this measure or slogan will continue to be effective, I doubt it. Our nation is very easy to forget, and we can't see it. In 2003, "SARS" was a trouble, and many people were vegetarians for a while. When the weather is fine, the rare birds and animals that run on the ground in the sky have become the appetizers of many foodies. This is not a long-term memory. What do you say is how good people are? It is said that the documentary "An In-convenientTruth" by former US Vice President Al Gore hides some secrets of the snowstorm. If the people know something from the roots, it is more likely to work than the temporary "saving electricity" measures.
