Oil exploration wells are scattered and numerous in number
2023年03月13日
Oil exploration wells are scattered and numerous in number, and abnormal phenomena need to be dealt with in time. Manual inspection takes a long time and has poor timeliness; wired transmission has many shortcomings such as cumbersome wiring, high cost, and no mobile network coverage on site.
Now there is a need for a wireless transmission technology that supports a large number of access, wide coverage, efficient data transmission, MIMO Technology and has a data center that can aggregate data for data collection, and then connect the network at the center to synchronize the data to the platform server for related data push and display .
working principle
A dormant terminal device is installed at each wellhead and connected to the three-axis sensor at the wellhead as an alarm node to monitor the status of each wellhead. And arrange the router (coordinator) terminal equipment and gateway equipment in the appropriate place to complete the construction of the entire data network.
(1) When the three-axis sensor with the wellhead detects that the wellhead state is abnormal, the three-axis sensor will send the abnormal data to the corresponding dormant terminal equipment;
(2) The dormant terminal will wake itself up at the first time and report the received abnormal data together with the node ID and latitude and longitude coordinates of the wellhead;
(3) The data is received and forwarded to the gateway device via router devices at all levels;
(4) After receiving the data, the gateway device transmits the data to the platform server through the 4G network, and the platform server performs alarm push and data presentation.
System composition
The entire data network is composed of dormant terminal equipment, router (coordinator) terminal equipment, and gateway equipment.

The challenges posed by the current Internet of Things

The challenges posed by the current Internet of Things system have given birth to a new network structure system. Over the past many years, a large number of standardized frameworks have been designed to solve many challenges and problems faced by the Internet of Things at a large scale.
At present, these frameworks all have the same basic requirement, which is to support the functional requirements of data, processes and terminal devices for execution. Serial Communication
The most famous of these are the frameworks defined by oneM2M and the Internet of Things World Forum (IOTWF). Below I will give an in-depth introduction to the two frameworks.
oneM2M IoT standard framework. In the process of standardizing machine-to-machine communication, the European Telecommunications Standards Institute (ETSI) created an association of technical application committees on M2M in 2008. The association was created to create a standard framework to accelerate people's M2M applications and M2M devices. Later, due to the worldwide recognition of the framework, the scope was extended to the field of Internet of Things.
After the M2M Technical Committee established the framework, other organizations also began to lay out the framework of the Internet of Things. In this context, Wi-Fi HaLow it is indispensable to specify a common M2M standard. After realizing the needs of the market, in 2012, ETSI and its member institutions launched a global initiative to unify the M2M framework. This initiative unifies the global M2M standard, accelerates the development of the Internet of Things Communication efficiency in communication systems and the Internet of Things. The purpose of the initiative is to create a common service layer, which can be directly nested into the device facilities, enabling service communication between devices. These include power grid interconnection, automotive hardware interoperability, industrial equipment health monitoring, intelligent measurement and other equipment interoperability services.
The OneM2M architecture roughly divides the functions of the Internet of Things into three architectures: application layer, service layer and network layer. Although the architecture looks very simple in the literal sense, its performance is very diverse. It not only allows each device to interoperate with each other through calling the IT networking interface, but also supports a large number of new and old IoT devices. technology.
