Description

Industrial data center system and working method

Technical Field

The invention relates to the field of information communication, in particular to the fields of an industrial automation control system and an internet of things communication sub-field, and particularly relates to a ship internet of things and an automation system.

Background

The existing industrial data center system adopts standard rack-mounted servers and rack-mounted switches, and terminals adopt respective independent power supplies and wiring, so that the cost of the whole project is high, the volume is large, the wiring is complex, and the management is inconvenient in some specific industrial places. In some applications, it is often necessary to control, e.g. turn on, turn off and manage, some network terminals. Furthermore, some network terminals do not consume much power in practice, but also require a power supply arrangement. For example, in a ship application, the scale of a common ship control and application system is not large, and a branch line container ship is taken as an example, and the number of information points is usually between dozens and dozens; the power consumption of the network terminal equipment is also very small, usually between a few watts and a dozen of watts, especially for some cabins, and the power supply needs to be turned off at any time due to explosion prevention. It is seen that the conventional centralized control of the power supply or the information point on-site power supply is inconvenient.

The existing POE (Power Over Ethernet ) Power supply technology solves the multiplexing network cable Power supply technology, but cannot meet the requirements of special application scenarios because each path of Power supply cannot be flexibly closed and opened, and data such as current and voltage of each path of Power supply cannot be monitored in real time.

It can be seen that the deficiencies of the prior art are apparent, and are at least reflected in the following aspects:

1. each network terminal requires power and wiring and is not able to control and monitor the power.

2. The data center end adopts a cabinet type design, has a complex structure and a large volume, and is not beneficial to maintenance and management.

3. The integration level is low, the equipment redundancy is high, the cost is high, the power consumption is large, and the reliability is low.

Therefore, there is a need to tailor a dedicated industrial data center for these specific application scenarios.
