The Functions and Applications of M2M Modem

The English name of M2M modem is Data Transfer unit, which literally translates as data transmission terminal. It realizes the function of data pipeline transmission in the Internet of Things system, and realizes the two-way data transmission between the local serial port data and the network server.

M2M Modem means that the local serial port data uses the 4G network of TD-LTE or FDD-LTE to realize wireless long-distance data transmission and data interaction with the remote public network server. It is mainly used for remote data acquisition and remote control projects.

M2m Modem Manufacturer's Brand and Model Selection

PUSR is a professional industrial M2M Modem manufacturer. The products have been strictly tested and passed the IS09001 quality management system certification, and the products have a number of global international certifications.

Advantages of M2M Modem over GPRS/3G Modem

• The amount of communication data is large

The 4G network has a maximum downlink rate of 100Mbps and a maximum uplink rate of 50Mbps. It provides customers with high-speed Internet access and wireless data connection, and is suitable for applications with large data transmission, such as serial camera image transmission.

• The communication speed is fast

Compared with the 2G/3G module, the M2m Modem has a lower ping value, and the time from the module sending a data packet to receiving a response from the server is shorter, so it is suitable for applications that require high response speed, such as remote alarm.

• Good compatibility

In addition to supporting FDD LTE/TD-LTE, M2M Modem is also downward compatible with 2G/3G and supports TD-SCDMA/WCDMA/EDGE/GPRS/GSM/CDMA1X/EVDO and other modes.

• Functions of M2M Modem

(1) Embedded standard TCP/IP protocol stack, 5 centers for transparent synchronous data transmission

M2m Modem is designed with standard TCP/IP protocol stack, and the transparent data transmission is simple and efficient. With the multi-center sending mechanism, the data can be sent to up to five centers at the same time, and the multi-level data display is more intuitive, which is convenient for the management of the data center. Support TCP server function and access to data center based on domain name and IP address.

(2) Standardized interface design, supporting RS232/RS485/TLL, I/O interface

Industrial terminal interface, suitable for industrial applications, RS232 or RS485 (or RS422) interface, can be customized TTL level serial port; Two-way analog, three-way switch design, can customize pulse output, pulse count and analog input function.

• Highly stable design for unattended environment

A three-level watchdog detection mechanism is adopt, and is composed of a watchdog design of a CPU, a hardware circuit watchdog design, a software watchdog design and other three-level multiple detection mechanism, so that running faults are self-repaired to ensure that that equipment never crash; TCP heartbeat link detection mechanism, disconnection reconnection and data reissue are adopted to ensure that the equipment is always online; It adopts the dual-channel design of short message and network.The network channel and the short message channel can be switched to each other. When TCP/UDP is disconnected, data can be sent by short message.

• More humanized design, more in line with the actual deployment needs of the site

Combined with 10+ years of delivery experience, the industrial standard installation pendant and industrial terminal wiring mode are adopted to facilitate on-site installation and construction. The M2m Modem configuration tool with humanized design integrates M2m Modem configuration tool, debugging tool and upgrade tool, and is more suitable for engineers to configure, upgrade and debug the equipment, so that the M2m Modem is simpler to use and more convenient to install.

• High standard industrial grade design, ideal for harsh industrial environments

Industrial standard selection devices, using industrial communication modules equipped with 32-bit ARM high-speed processors, all devices 100% meet the industrial application standards, super moisture-proof, lightning protection, anti-electromagnetic interference capabilities; Ultra-low power consumption design, communication state power consumption < 1W, sleep state power consumption < 0.1W, more suitable for industrial sites with difficult power supply; Wide voltage design, 5-35V (voltage can be customized),Wider working temperature, wider power supply voltage, adapt to more power supply sites.

It is easy to realize remote monitoring and management of equipment and save more manpower and material resources.

M2m Modem supports multiple online and offline trigger modes such as SMS, telephone ringing, serial port data, etc.; Support remote configuration and upgrade via TCP/IP channel, and support parameter configuration and data receiving and sending via SMS; Wireless transmission equipment supports remote firmware upgrade and remote troubleshooting, which can easily realize remote monitoring and management of equipment and save more manpower and material resources. Support the DTU management platform,Easy centralized device management and deployment

M2m Modem application field

The M2M Modem is suitable for use in an environment where networking is not convenient to realize the transmission of a large amount of data.

Such as: urban air quality monitoring, sewage treatment detection, intelligent transportation, agricultural intelligent irrigation, industrial Internet of Things, intelligent manufacturing, online monitoring of transmission lines, logistics vehicle scheduling management, water level detection, water source well monitoring, pipe network pressure detection, gas pipe network wireless remote monitoring, oil field remote monitoring.
