The Industrial Internet of Things (iot) is a scenario with high requirements for availability, reliability and robustness.

Iot devices are typically deployed in unattended or industrial rigors in complex environments. For example, underground mine pipes, rooftops, lampposts, suburbs, etc., on-site maintenance and repair is not so convenient, and the daily rain shower equipment is easy to age or be damaged by external accidental factors. If there is no redundant design, the centralized control center will need a lot of daily maintenance and repair. It will bring a very large workload and a very large responsibility safety hazard to the operation and maintenance personnel. If it is an entrepreneurial project, it may even lead to the complete failure of operation in the later stage of the project.

Therefore, the Internet of Things networking should consider the extreme cases of equipment damage and line damage. In general, there should be active and standby networks and active and standby devices. In case of failure, another set of Plan B can also be started.

The high availability of the industrial Internet of Things system requires redundant design, topology structure of the ring fiber communication network, multi-channel communication interface, wired + wireless Internet transmission and so on are all the priority objects in the equipment selection. It is a very important factor to consider whether the device of the Internet of Things supports the acquisition of active and standby devices, communication of active and standby systems, and intelligent active and standby switchover. The integrator of the Internet of Things system should also consider supporting redundant design and main and standby network design in the networking design, so as to avoid the trouble of maintenance and repair, such as not receiving complaints in time and requiring more labor costs in timely repair. Two communication solutions for two devices, active and standby, can make operations more secure and Internet of Things systems more reliable.

Highly reliable, robust, and stable Internet of Things system integration scheme is a must for various scenarios such as smart digital factory, smart transportation, smart rail transit, smart municipal, smart tap water, smart underground pipeline, smart prison, smart city emergency, smart police, smart security, smart industrial control, etc.

The Internet of Things is a new digital infrastructure, therefore, we must have the responsibility to invest in public infrastructure to do the physical networking system project, not a shoddy project, can be used, the subsequent harm is endless, even bring public safety risks, imagine a public water table security monitoring system failure, who can be responsible?

The Internet of Things is a core element of the new infrastructure

For example, monitoring the safety and health status of public infrastructure -- preventive maintenance of bridge collapses -- requires the use of iot sensors to collect large amounts of data that can be used to drive artificial intelligence and machine learning. Building managers have to perform predictive maintenance on a large number of urban facilities, and measure various professional data to correct the data, and finally use these data to predict the building will have problems. This allows the person in charge to identify the problem early and proactively and maintain it. By installing iot sensors on buildings, the comfort of all buildings can be monitored 24/7. If there is a crack or a local deformation, the sensor will send an alert to the person in charge, reducing the risk of an accident.

For example, during a pandemic, sanitation issues, by monitoring problems such as garbage collection and pest infections, iot devices allow government officials to see where problems exist in a city and how to solve them. Iot devices can also analyze a pool's temperature, pH, and more.

As an important part of modern new information infrastructure, the Internet of Things is an important direction and driving force for a new round of industrial reform, supporting the development of social and economic digital transformation, and ultimately building a digital twin society of comprehensive perception and ubiquitous connectivity.
