DTU和IoT网关之间的区别

What is the difference between DTU and IoT gateway

The data transfer unit DTU (Data Transfer unit) is a wireless terminal device specially used to convert serial data to IP data or convert IP data to serial data to be transmitted through a wireless communication network. The entire Netcom DTU covers the entire network, and the Internet of Things gateway is also Can carry out data transmission, so what is the difference between Netcom DTU and IoT gateway?

　　 1. DTU is a long connection, which consumes system resources. If the remote terminal exceeds 500, it usually uses multiple server groups to manage it. Usually, it is necessary to purchase a professional cloud server, and the cost is more than 100,000 yuan per year. What we collect is UDP or HTTP for push, and the cost is about one-fifth of the former.

　　2. DTU has a short life cycle, because DTU has a single function, which is to perform data transparent transmission. The user's function is ever-changing. When the demand cannot be met, it may need to be replaced. The cycle is usually 1 to 2 years. The expansion of the gateway is good, the development of different plug-ins to achieve different functions, using the remote management function, you can change the business requirements at any time, and it can exist with the existence of the mobile network.

　　 Comparison of other advantages and disadvantages between DTU and IoT gateway

　　 The DTU gateway can only transmit transparently, and the protocol library is rich. It can analyze various protocols and protocol access without network interruption. The data is cached on the disk, and after the network is restored, it can be transmitted to the server. The data is always coherent. Remote management capabilities without built-in VPN, remote management, remote upgrades, remote modification of the transmission cycle, remote adjustment of the inverter operating parameters, how much traffic is used, built-in optimization algorithm, the use of change transmission services is not strong, and can be added at any time Services, such as adding a power collection function.

　　 What are the types of DTU?

　　 According to different DTU data transmission methods, DTU has GPRS DTU, WIFI DTU, CAN DTU, 4G DTU, GPRS-DTU.

　　DTU application field introduction

　　DTU has been widely used in power, environmental protection, LED information release, logistics, hydrology, meteorology and other industries. Although the applied industries are different, the principles of application are the same. Most of the DTUs are connected to industrial equipment, such as PLCs, microcontrollers and other automation products, and then establish a wireless communication connection with the background. Today, with the increasing development of the Internet, DTU is used more and more widely. It provides help for various industries and the integration of information and industries among various industries. It has gradually developed into the core technology of IoT applications.
