Description

TECHNICAL FIELD

[0001] The utility model relates to power router monitoring technical field especially relates to a rack type power router monitoring device. BACKGROUND

[0002] With the increasing dependence of modern society on electronic devices and power systems, the stability and continuity of power supply become particularly important. In critical areas such as communication, medical treatment, monitoring, power interruption or fluctuation may cause catastrophic consequences, leading to equipment downtime, data loss and even personnel injury. Therefore, ensuring the stable operation of power equipment, especially in the event of power failure, has become an important problem to be solved in the field of power control and management.

[0003] Traditional power equipment control and management devices usually rely only on main power supply. Once the main power supply fails or is powered off, the device will not continue to run, affecting the reliability and stability of the system. In addition, the existing control devices generally have the following problems: on the one hand, most of the devices are complex in design, and the power management is not flexible enough to ensure the continuous operation of the device when the power is interrupted; on the other hand, many devices lack intelligent control and monitoring functions, resulting in delayed monitoring of power supply status and inability to provide effective fault warning and response. In addition, the existing system also faces problems such as poor compatibility between devices and non-uniform communication protocols, which makes it difficult to achieve efficient linkage and centralized management between different devices.

[0004] In order to improve the stability and reliability of power equipment, existing technologies gradually turn to the direction of intelligence and integration. Integrating multiple functional modules and managing them through a unified control platform has become a trend to solve the above problems. Through intelligent power management technology, the system can automatically switch to backup power supply when the main power supply fails, ensuring the continuity of the system. In addition, through high-precision voltage acquisition, real-time state detection, intelligent communication and other technologies, the system can monitor the power supply and equipment running status in real time and make corresponding adjustments and controls according to the actual situation, greatly improving the reliability and safety of the power system.

[0005] At present, as an important part of power control and management, rack-mounted power routers gradually develop towards integration and intelligence in their functional design. Traditional rack-mounted power routers often only have basic power transmission functions, while modern rack-mounted power routers not only can realize efficient routing of power, but also can integrate various power monitoring and management functions, such as intelligent management of power modules, voltage acquisition and analysis, multi-protocol support of communication modules, state detection and control, etc., to meet the needs of various complex power environments.

[0006] Therefore, the rack-mounted electric energy router monitoring device with integration, intelligence and easy maintenance can effectively solve the defects of the existing power equipment control management system, ensure the stability and continuity of power supply, improve the operation safety and reliability of the equipment, and has important technical value and application prospect. The design of the device not only can simplify the management and maintenance of the equipment, but also can realize the all-round monitoring and intelligent control of the power system, meet the increasingly complex and intelligent demand of the modern power system.
