As a highly integrated and comprehensive application of the new generation of information technology, the Internet of Things is one of the strategic emerging industries that the country has fostered. In recent years, the province's Internet of Things technology has developed rapidly and has comparative advantages in UHF RFID, core control chips, and short-range wireless communication technologies. A number of scientific research units and enterprises such as the National University of Defense Technology, Hunan University, and the China Electronics 48 Institute also undertake research and development of a number of national major issues and projects in the field of the Internet of Things.
According to preliminary statistics, as of the year 2010, there were 249 companies in the province engaged in R&D, production, and service of the Internet of Things, and the annual sales revenue of the Internet of Things industry exceeded 17 billion yuan. It covers most aspects of the internet of things industry, including sensors, chip design, electronic tags and read/write devices, smart terminals, application software, system integration, and operations services. In areas such as intelligent high-speed train control, smart metering, mobile mobile payment, financial tax control equipment, and remote control of small and medium-sized hydropower stations, the technology innovation and market share of some enterprises in our province are in a dominant domestic position. Among them, Godson's information security products of “China Kebohua†are recommended by the Ministry of Industry and Information Technology and entered the Central Government Procurement Catalogue, and are widely used in many important industries such as education, health, and social security.

Strive to 2015, the province's Internet of Things industry output value reached 80 billion yuan.
Drilling BOP And Control System
During oil drilling, it is installed on the wellhead casing head to control high-pressure oil, gas, and water blowout devices. When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (shut down). When the heavy mud is pressed into the drill pipe, there is a four-way under the ram, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the ejection of high-pressure oil and gas.
Its types are divided into ordinary blowout preventer, universal blowout preventer and rotary blowout preventer. The universal blowout preventer can be activated in emergency situations to deal with any size of drilling tools and empty wells; the rotary blowout preventer can realize the blowout and drilling operation. In deep well drilling, in addition to two ordinary blowout preventers, universal blowout preventers and rotary blowout preventers are often added, so that three or four combinations are installed at the wellhead.
Annular Blow-out Preventer Annular Blow-out Preventer is usually equipped with a large gate with a ram-type blowout preventer. During operation, a sealed annular space is formed between the pipe string and the wellbore. When there is a pipe string in the well, it can also be separated The well is closed, but it will not work after several times of use, and long-term shut-in use is not allowed.
