Description

Technical Field

[0001] This utility model belongs to the field of DCS power system monitoring technology, and specifically relates to an online monitoring and early warning system for DCS power systems. Background Technology

[0002] As the core of the unit's control system, the DCS (Distributed Control System) is an important guarantee for the safe and stable operation of the unit. When the DCS controller experiences a power failure alarm, the DCS power failure emergency plan should be activated in a timely manner to find out the cause as soon as possible, eliminate the defect, avoid prolonged operation of a single power supply, and prevent the unit from being unmonitored due to a power failure of the DCS system, which could lead to unpredictable and serious consequences.

[0003] Currently, in actual operation, due to reasons such as untimely inspections, DCS system shutdowns still occur due to power outages. Furthermore, because staff can only periodically check the DCS power supply, it is difficult to monitor the power status of the DCS system in real time, and alarms cannot be issued promptly, leading to abnormal power supply or safety malfunctions. Utility Model Content

[0004] The purpose of this invention is to provide an online monitoring and early warning system for DCS power systems, thereby overcoming the aforementioned shortcomings. The specific technical solution is as follows: A DCS power system online monitoring and early warning system includes a DCS logic unit, a switching monitoring unit, a power node monitoring unit, a cabinet monitoring unit, and an early warning unit. The power node monitoring unit is used to monitor the power failure status of the main power node and the backup power node, and send the power failure signal to the DCS logic unit. The switching monitoring unit is used to monitor the switching status between the main power node and the backup power node, and send the switching signal to the DCS logic unit. The cabinet monitoring unit is used to monitor the fire situation inside the cabinet and send the status inside the cabinet to the DCS logic unit in real time. The early warning unit is used to receive instructions sent by the DCS logic unit to issue an alarm.

[0005] Preferably, the power node monitoring unit includes a power failure monitoring unit; The power failure monitoring unit is used to receive a power failure signal sent by the power node monitoring unit. When the main power node fails and loses power, the main power node sends a first power supply command to the backup power node so that the backup power node supplies power according to the first power supply command; and sends a first power failure status signal to the DCS logic unit. When the backup power node fails and loses power, the backup power node sends a second power supply command to the main power node so that the main power node group supplies power according to the second power supply command; and sends a second power failure status signal to the DCS logic unit.

[0006] Preferably, the power failure monitoring unit includes a voltage sensor, a current sensor, and a power monitoring sensor.

[0007] Preferably, the cabinet monitoring unit includes a temperature sensor, a smoke detector, and a camera. The temperature sensor is used to acquire the temperature of the cabinet, the smoke detector measures the early fire situation, and the camera acquires the fire situation inside the cabinet and sends the acquired information to the DCS logic unit.

[0008] Preferably, the early warning unit is an audible and visual alarm.

[0009] Preferably, the switching monitoring unit includes a switching time monitoring unit, which is used to monitor the switching time between the main power node and the backup power node.

[0010] Preferably, it also includes an isolation module, which is installed in each of the main power node and the backup power node. The isolation module is used to isolate the power supply in the event of a power failure.

[0011] Preferably, it also includes a power failure data display module, which is connected to the DCS logic unit and is used to display the power failure status of the main power node and the backup power node.

[0012] Compared with existing technologies, this utility model has the following beneficial effects: 1. In this utility model, the power monitoring unit can monitor the main power node and the backup power node in real time. When one of them is found to be in a power failure state, an early warning is issued in time, and the system switches between the main power node and the backup power node to ensure the safety of power supply.

[0013] 2. In this utility model, the switching monitoring module can monitor the switching status of the switching device in real time. When the switching device malfunctions, it can be detected in time and an early warning can be issued. At the same time, when it is found that the switching time is too long and affects the power supply quality, an early warning can also be issued in time to notify the staff to carry out maintenance in a timely manner.

[0014] 3. In addition to providing early warning of power failure status of the main power node and the backup power, this utility model can also perform real-time monitoring of the fire status of the cabinet. When a safety hazard is detected in one of them, the power supply can be isolated in time, thereby improving the safety of the entire system. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0021] Example 1 like Figure 1 As shown, an online monitoring and early warning system for DCS power systems includes a DCS logic unit, a switching monitoring unit, a power node monitoring unit, a cabinet monitoring unit, and an early warning unit. The power node monitoring unit is used to monitor the power failure status of the main power node and the backup power node, and send the power failure signal to the DCS logic unit. The switching monitoring unit is used to monitor the switching status between the main power node and the backup power node, and send the switching signal to the DCS logic unit. The cabinet monitoring unit is used to monitor the fire situation inside the cabinet and send the status inside the cabinet to the DCS logic unit in real time. The early warning unit is used to receive instructions sent by the DCS logic unit to issue an alarm.

[0022] In the above scheme, the power node monitoring unit is used to monitor the power failure status of the main power node or the backup power node and send it to the DCS logic unit to promptly detect whether the main power and backup power are in a power failure state. If a power failure state is detected, an early warning report is issued through the early warning unit, and a switching device is used to switch to ensure the normal power supply of the power supply system. At the same time, when a fire occurs in the cabinet, the cabinet monitoring unit can quickly detect and issue an early warning, such as taking measures such as power supply isolation to avoid a larger safety accident.

[0023] As a further embodiment, the power node monitoring unit includes a power failure monitoring unit; The power failure monitoring unit is used to receive a power failure signal sent by the power node monitoring unit. When the main power node fails and loses power, the main power node sends a first power supply command to the backup power node so that the backup power node supplies power according to the first power supply command; and sends a first power failure status signal to the DCS logic unit. When the backup power node fails and loses power, the backup power node sends a second power supply command to the main power node so that the main power node group supplies power according to the second power supply command; and sends a second power failure status signal to the DCS logic unit.

[0024] As a further embodiment, the power failure monitoring unit includes a voltage sensor, a current sensor, and a power monitoring sensor.

[0025] It is understandable that voltage sensors, current sensors, and highway detection sensors can monitor the voltage, current, and power of the main power supply node and the backup power supply node in real time. When an abnormality occurs, they can promptly detect the power supply failure and issue an early warning.

[0026] As a further embodiment, the cabinet monitoring unit includes a temperature sensor, a smoke detector, and a camera. The temperature sensor is used to acquire the temperature of the cabinet, the smoke detector measures the early fire situation, and the camera acquires the fire situation inside the cabinet and sends the acquired information to the DCS logic unit.

[0027] It's understandable that overheating of the server rack can be detected using temperature sensors, while early-stage minor combustion within the rack can be detected by smoke detectors. Combined with images captured by cameras within the rack, this information can be processed using a YOLO neural network for image recognition, offering high efficiency and accuracy. This method can process large amounts of image data quickly and accurately identify flames. Upon detecting a flame, the system immediately triggers an alarm to alert people to evacuate as quickly as possible.

[0028] As a further embodiment, the early warning unit employs an audible and visual alarm.

[0029] As a further embodiment, the switching monitoring unit includes a switching time monitoring unit, which is used to monitor the switching time between the main power node and the backup power node.

[0030] It is understandable that the switching time between the main power node and the backup power node may also cause power supply abnormalities. When the switching time is too long, the DCS logic unit sends a command to the early warning unit to issue an early warning message and carry out maintenance on the switching node to ensure that the power supply switching action is completed within the specified time and to ensure the quality of power supply.

[0031] As a further embodiment, an isolation module is also included, wherein each of the main power node and the backup power node is equipped with the isolation module, which is used to isolate the power supply in the event of a power failure.

[0032] It is understandable that during power supply, when the main power node or the backup power node loses power, the corresponding power supply is isolated, or in the event of a fire in the cabinet, the power supply is isolated to improve the safety of the power supply system.

[0033] As a further embodiment, a power failure data display module is also included. This module is connected to the DCS logic unit and is used to display the power failure status of the main power node and the backup power node. It can be understood that the power failure data display module is used to display real-time data for each power supply and the server rack.

[0034] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. The purpose of selecting and describing exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art, after reading this specification, can make modifications, substitutions, variations, and various choices and changes to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, variations, and choices and changes are within the scope of the claims of the present invention and are protected by patent law.
