[Industry Background]
Wireless data acquisition and transmission is an important collection and networking mode in industrial Internet data communication, which involves a wide range of industrial applications. In business equipment, industrial field such as environment, for example, there are many cable cannot reach the scene, using DTU wireless data unit can be dedicated to a serial port and IP data conversion between, and through the data transmission on the wireless network, widely used in electrical energy, industrial automation, automatic meter reading, the wisdom city, vehicular traffic, environmental monitoring, equipment monitoring, etc.
[Solution]
With the maturing of the Internet of things technology, various industries all kinds of urgent demand equipment connected to the Internet increases, witty cloud on the Internet industry launched commercial/industrial equipment life cycle management, operating the overall solution, through the most cost-effective hardware solution, precipitation and company for many years the leading iot cloud platform technology, providing the pipe end to enterprise integration products and services, Reduce the cost of product research and development for the combination of software and hardware, and help enterprises speed up operation and service.
01 Troubleshooting
Realize the industrial/commercial equipment life cycle of the whole process of the closed loop application, contains hardware scheme, basic links, user management, equipment sharing, equipment management, equipment monitoring, scene services, rules engine, news feeds, voice services, data services, equipment log, OTA upgrade, location map, forecast alarm APP, users, etc.
02 Advantages of the scheme
* Easy access: With years of accumulation of Internet of Things platforms, DTU has built a perfect commercial Internet of things communication mechanism. Users only need to realize the basic serial protocol to connect to the smart cloud platform. At the same time, the platform can also actively adapt to customer product agreements, and customer devices can connect to The Smart Cloud without any modification.
* Strong compatibility: support Wi-Fi, 2G, 4G, NB-iot, LoRa, Bluetooth Mesh, Zigbee, 485, 232, Modbus, KNX, wired and other communication modes, can docking mainstream industrial protocols. Connects to the service system.
* Wide application scenarios: industrial circuit board design, built-in lightning protection, anti-static design, can be used in harsh industrial environment.
* High safety factor: the hardware design adopts the chip SIM card design, with good earthquake resistance. Function with identity authentication and remote access security mechanism and data encryption.
* Intelligent cloud platform data communication and basic capabilities are safe and stable to achieve large-scale equipment development, control and big data services, which can help enterprises to achieve docking with business operation system and create data and operation closed loop for enterprises.
03 Implementation Objectives
* Cloud platform can realize remote access, data acquisition, real-time monitoring and fault alarm and other requirements, and through the background management system intuitive presentation.
* Operation management personnel can remotely monitor the operation of equipment in real time through mobile client (APP) and receive active fault alarm information from cloud to ensure the optimization of various operation indicators.
* Excellent security performance, providing telecom carrier-level stable and reliable, safe and reliable wireless network transmission channel, with identity authentication and remote access security mechanism and data encryption.
* Open apis can freely connect to edge computing services, third-party mobile payment platforms and other value-added services from third-party platforms that can be upgraded in the cloud.
