As the Internet of Things gradually invested in modern life, many communication technologies have emerged. The following is knowledge of M2M technology.
What is M2M technology?
Machine-to-machine (M2M) communication technology is used for automated data transmission and measurement between mechanical or electronic devices.
M2M is effective to control the device through mobile communications, thereby significantly expanding or creating a more efficient business in the traditional way or creating a new service that is completely different from traditional methods.
The M2M is transmitted from one terminal to another, which is the concept of information exchange between the machine and the machine, transmitting the communication with the link through the network and machine device to meet the concept of information sharing.
What is M2M composition?
M2M involves five important technical parts: machine of M2M, M2M hardware, M2M communication network, M2M middleware, M2M application.
What is an M2M machine?
The first step in achieving M2M is to obtain data from the machine, and then send them through the network. Enable the machine “Talk”, let the machine have information awareness, information processing (computing power), wireless communication capabilities.
There are two basic methods for “speaking” capabilities: embedding M2M hardware when producing equipment; modifying the existing machines, enable communication and networking capabilities.
What is M2M hardware?
M2M hardware is a component that allows the machine to get remote communication and networking capabilities. Mainly for information, acquiring data from various machines/devices, and transmitting it to the communication network.
The current M2M hardware is divided into five: embedded hardware, capable hardware, modem, sensor, and identification tags.
Embedded hardware:
The hardware is embedded into the machine to enable it to have network communication capabilities. Common products are wireless embedded data modules that support GSM / GPRS or CDMA wireless mobile communication networks.
Can be assembled:
In M2M industrial applications, manufacturers have a large number of equipment instruments that do not have M2M communications and networking capabilities, which can be modified to meet the network communication capabilities of these machines.
The implementation form is also different, including the I/O device of the data from the sensor; Completing the protocol conversion function, and sending data to the connection terminal of the communication network; some M2M hardware also has an upload Function. Typical products include Nokia 30/31 for GSM connection terminals.
Modem:
The embedded module is mentioned in the mobile communication network. When it is up, it is the function of the modem. If you want to send data through a public telephone network or Ethernet, you need a corresponding modem.
Sensor:
The sensor can be divided into two types normal sensors and intelligent sensors. Intelligent sensors refer to micro-sensors with perceived ability, computing power, and communication capabilities. The sensor network consisting of intelligent sensors is an important part of M2M technology.
A group of intelligent sensors with communication capabilities constitute a wireless network, collaborate awareness, acquisition, and handle information in a geographic area of the network, and publish it to the observer; Can also pass the information through the GSM network or satellite communication network. Give a distant IT system.
Location tags:
Identify the identity of each machine, and the ID card of each item, enabling the machine to identify and distinguish between each other. Commonly used techniques such as barcode technology, RF identification card RFID technology, etc. Identification technology has been widely used in commercial inventory and supply chain management.
What is M2M communication network?
Network technology has completely changed our lifestyle and survival, and we live in a network society. Today, the emergence of M2M technology makes the connotation of the network society have new content.
In addition to the original person, computer, and IT equipment, members of the network society, are to join in. With the development of M2M technology, the number of new members and their data exchange will increase rapidly.
Communication networks are in a core status throughout the M2M technology framework, including WAN (wireless mobile communication network, satellite communication network, internet, public telephone network), LAN (Ethernet, Wireless LAN WLAN, Bluetooth), Domain Network (Zigbee, Sensor Networks).
In the communication network in the M2M technology framework, there are two major participants, they are network operators and network integrators. In particular, mobile communication network operators play a crucial role in driving M2M applications, they are the main promoters of M2M technology applications.
In addition to providing voice services, and third-generation mobile communication technologies, the development of data service services is the focus of its development. With the evolution of mobile communication technology to 3G, it is certain to bring M2M applications to a new realm.
What is M2M middleware?
The middleware includes two parts: M2M gateway, and data collection / integrated components.
The M2M gateway is a “translator” in the M2M system, which acquires data from the communication network and transmits the data to the information processing system. The main function is to complete the conversion between different communication protocols.
Data collection / integrated components are to turn data into valuable information. Different processing and processing for raw data, and presented the results to observers and decision-makers that need this information.
These middleware include data analysis and business intelligence components, abnormal conditions reports, and workflow components, data warehouses, and storage components.
What is M2M application?
Data collection/integrated components are to turn data into valuable information. Different processing and processing for raw data, and presented the results to observers and decision-makers that need this information.
These middlemen include data analysis and business intelligence components, abnormal circumstances reports, and workflow components, data warehouses, and storage components.
What is M2M application field?
M2M technology provides integrated solutions integrated with integrated data in all walks of life and implements business processes, and industrial processes have become automated.
The main applications include transportation, logistics management, (positioning navigation), power field (remote meter reading and load monitoring); agricultural sector (greenhouse monitoring, animal traceability); urban management (elevator monitoring, street light control); security field (city And enterprise security); environmentally friendly field (pollution monitoring, soil testing); enterprise (production monitoring and equipment management); and home (old man and child care, intelligent security), etc.
As can be seen above, M2M is a networked application and service with the intelligent intersection of machine terminals. With the development of science and technology, more and more equipment have communication and networking ability, and the network has gradually become reality.
