What are the considerations for choosing the communication protocol between the fault recording device and the host computer?

The MQTT protocol, as a lightweight publish/subscribe model, is designed specifically for IoT scenarios and is suitable for low-bandwidth, high-latency networks.

How can hardware redundancy design be implemented in autonomous and controllable industrial computers?

Dual NIC bonding technology virtualizes two physical NICs as a single logical interface, automatically switching links when either NIC fails to ensure network continuity.

Does the time synchronization device have electromagnetic interference and lightning protection designs?

In modern power system operation, time synchronization devices are no longer auxiliary equipment; they serve as the "nerve center" supporting relay protection, fault recording, dispatching automation, and coordinated control of smart substations.

Are autonomous and controllable industrial computers highly reliable?

In modern industrial systems, industrial computers are not only the "brains" of automated control but also the core hub connecting production, monitoring, scheduling, and decision-making.

Why does the small current grounding line selection device effectively improve the identification of high-resistance ground faults?

The small current grounding line selection device fundamentally solves the difficulty of identifying high-resistance grounding faults by integrating steady-state and transient information, employing a fuzzy decision-making mechanism.

How does a small current grounding line selection device achieve multi-circuit synchronous monitoring and rapid fault location?

Communication and data management functions provide extended support for troubleshooting of small current grounding line selection devices.
