20 years, the progress of China's earthquake observation techniques and recent developments humble opinion
And workstation systems and various auxiliary equipment package, the choice of wireless or wired communication channel can be observed to satisfy different mission requirements of the various types of digital telemetry seismic network. China Seismological Bureau, generation, in this century, with modern advanced digital seismic observation system replacement is still used outdated analog seismic observation system, seismic technology to make our leap into the world advanced level in one fell swoop, for the next century, seismology and earthquake prediction and earthquake relief work to provide high-quality observational data base and make new contributions. The world has entered the information age, a large number of high-tech is emerging to the fore, can almost be said every day the world heard a variety of new products, a number of related technologies as an integrated form of seismic technology, as future development will also The pace of the times, made new achievements now it is difficult to predict. In this, I can only grasp some of the personal current meager knowledge, combined with the domestic situation, the future development of this branch of technology,
Hogan sito, prospects, and colleagues made a few comments questionable, inappropriate, please let me know. At present, many foreign manufacturers of packaging size,
Hogan sito ufficiale, low power consumption, power can control a variety of new integrated circuit logic and special components have in the domestic market. Using these components and the recent launch of the embedded operating system supports 16-bit and 32-bit embedded central processing unit with the GPS signal receiver and other necessary auxiliary equipment, heavy energy than the rechargeable lithium-ion battery. In a variety of self-developed application software support, you can develop a set of small size, light weight, low power consumption, high reliability and low maintenance, with new solar-powered data logger. Output signal is available in several communications systems currently used for transmission if the use of environment has been available for near-earth orbit satellite systems (such as the Iridium system) to transmit, the common communication system that the device will be relatively large as the size of the phone replaced by the transceiver, and the choice of observation points provides a very free space. Indeed, for long-term continuous use of such systems, it is quite expensive and almost impossible to bear the charges. But it can be used to trigger data compression and transmission technologies, such as mobile phones transmit the required information in a short time as the method to resolve. I might create conditions intended to make some pre-research and test work. And I think this is a global commercial communications through the system, over time there will not be long before the world of millions of users,
a buon mercato Hogan scarpe, the tariff will be on the decline. If the trial is successful, according to need long-term continuous use of such systems will become reality. Some foreign manufacturers to produce integrated circuits, micro-payment processing (micromachine) and integrated circuit manufacturing technology, small size and prestige has been manufacturing low-cost single-and dual-axis integrated accelerometer. Although the dynamic range of such products is relatively small. But in the record 0.0lcm / s acceleration stag value. Still higher signal to noise ratio. Therefore, if with low power consumption, fast operation, with more than 5 sheets rustic Lin: 2n years, China's earthquake-ship Chau technological progress and recent developments in the humble opinion of the microcontroller ADC 13 Road and to study and prepare a set of acceleration data using real-time record can immediately calculate the intensity value of the software. Can be developed into a low-cost intensity meter. If a selected region of interest to run a number of observation points such intensity meter, while among the earthquake and the seismic waves crossing the region, will be able to promptly calculate the intensity value of each observation point, control the distribution of intensity in the region. If using a temporary means of communication will be promptly transmitted to the intensity values of leadership and management,
Ed Hardy Summer intraseasonal oscillation of the m, can be pre-programmed according to the area of earthquake damage prediction maps, determine the distribution of disaster, so that authorities can make a timely and targeted emergency relief program. Contribute to reduce disaster losses. In addition, this system is in place to carry out a certain distance of the earthquake early warning is also quite useful.
