Description

Technical Field

[0001] This application belongs to the field of industrial control and relates to a multi-parameter online monitoring system and method for equipment mounting. Background Technology

[0002] Large, high-speed rotating equipment is a key component of industrial production systems, and its long-term stable operation significantly impacts the safety, continuity, and efficiency of the production line. This type of equipment is typically mounted on dedicated racks or support structures and equipped with power supply, cooling, monitoring, and protection devices. Because the equipment operates at high speeds for extended periods, the rack structure, power supply connections, cooling pipes, and the equipment itself can all be affected by factors such as vibration, temperature rise, leakage, and poor contact, potentially leading to operational hazards.

[0003] Currently, existing equipment mounting systems rely heavily on existing protection devices for condition monitoring. These devices have relatively limited functions, typically monitoring only basic parameters such as equipment speed and vibration amplitude. Comprehensive assessment of equipment operating status still largely depends on manual inspections or post-maintenance procedures. As production lines expand and the requirements for continuous equipment operation increase, single-parameter monitoring methods are no longer sufficient to promptly reflect early abnormal conditions and cannot adequately meet the needs of equipment health prediction, early fault warning, and refined operation and maintenance management.

[0004] Specifically, the existing technology mainly has the following problems: First, insufficient vibration monitoring capabilities make it difficult to detect early equipment deterioration in a timely manner. Large rotating equipment may experience abnormal vibrations during long-term operation due to rotor wear, installation deviations, loose fasteners, deformation of support structures, or fluctuations in operating conditions. In the early stages of anomalies, the equipment speed may not yet show significant changes, making it difficult for traditional protection devices to promptly identify trends in equipment deterioration. Failure to detect anomalies early through changes in vibration characteristics and to take intervention measures may result in missed optimal maintenance opportunities, impacting equipment lifespan and production continuity.

[0005] Secondly, the lack of automatic monitoring for cooling water pipe leaks poses a safety hazard. To ensure the long-term stable operation of equipment, cooling water pipes and multiple pipe joints are typically arranged around the mounting frame. Due to factors such as mechanical vibration, aging of seals, installation misalignment, or long-term operational fatigue, minor leaks may occur at pipe joints or connections. Minor leaks can lead to equipment corrosion, decreased insulation performance, or deterioration of the local environment; in severe cases, they may affect the safety of electrical components or even cause equipment shutdown. Current leak detection methods mostly rely on manual inspections, which are inefficient and easily affected by inspection cycles, available space, and personnel experience, posing a risk of missed detections.

[0006] Third, the lack of real-time temperature monitoring at power supply connections poses a risk of overheating. Power busbars or connections within the equipment rack supply power to the equipment, and during long-term operation, localized overheating may occur due to contact aging, loose connections, increased contact resistance, or component defects. If temperature changes cannot be monitored in real-time and alarms are not triggered promptly, it could lead to insulation aging, electrical faults, or even fire risks. Currently, temperature monitoring at power supply connections typically relies on manual measurement or periodic inspections, making continuous, real-time, and automated monitoring difficult.

[0007] In summary, existing protection methods that primarily monitor rotational speed or single vibration amplitude, along with operation and maintenance modes reliant on manual inspections, are insufficient to meet the requirements of high reliability, continuous operation, and intelligent operation of large industrial equipment. Therefore, it is necessary to propose an online monitoring system capable of real-time acquisition, comprehensive judgment, and remote alarm for multiple parameters, including power supply connection temperature, cooling water leakage, equipment vibration, and equipment rotational speed, to improve equipment operational safety and achieve a shift from reactive maintenance to predictive maintenance. Summary of the Invention

[0017] Optionally, the microcontroller has a built-in diagnostic algorithm for making a comprehensive judgment based on at least two parameters among temperature, water droplet state, and vibration amplitude to obtain the operational health status of the equipment rack.

[0018] Optionally, when the microcontroller determines that any monitoring parameter exceeds a preset safety threshold or exhibits an abnormal trend, it generates a corresponding alarm signal and identifies the type of monitoring parameter that is abnormal.

Detailed Implementation

[0026] To enable those skilled in the art to better understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only a part of the embodiments of this application, and not all of them. Based on the embodiments described in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a multi-parameter online monitoring system for equipment racks, applied to an equipment rack 7 including a power busbar 1 and cooling water pipes 4. The system includes a temperature sensor 2, a water droplet sensor 3, a measuring box 5, a vibration sensor 6, and an upper-level monitoring system 14. The temperature sensor 2, water droplet sensor 3, and vibration sensor 6 are respectively arranged at different monitoring positions on the equipment rack 7 and connected to the measuring box 5 via cables; the measuring box 5 is used for centralized processing, analysis, judgment, and data uploading of the signals collected by each sensor.

[0028] In one specific embodiment, the temperature sensor 2 is disposed at the power busbar 1 of the equipment mounting bracket 7, preferably at or near the wiring bolt of the power busbar 1. Since the connection point of the power busbar 1 may experience local temperature rise due to poor contact, loose connection, or increased contact resistance during long-term operation, placing the temperature sensor 2 at the above-mentioned location allows for direct acquisition of the temperature signal near the connection point of the power busbar 1, thereby facilitating timely detection of abnormal temperature rise in the power supply connection area.

[0029] In one specific embodiment, the temperature sensor 2 is a contact-type resistance temperature detector (RTD) sensor, such as a platinum RTD sensor. The detection end of the temperature sensor 2 is in contact with or adjacent to the part to be measured on the power bus 1, and its output end is connected to the first signal conversion circuit 8 inside the measuring box 5. The first signal conversion circuit 8 is used to convert, amplify, and filter the resistance signal output by the temperature sensor 2 to form a signal suitable for acquisition by the acquisition circuit 11.

[0030] In one specific embodiment, the water droplet sensor 3 is disposed near the joint, pipe connection, pipe support joint, or other easily leaking location of the cooling water pipe 4. The water droplet sensor 3 is preferably a contact-type water droplet sensor. When its detection surface comes into contact with liquid water, the resistance value of the detection surface changes, and the water droplet sensor 3 outputs an electrical signal indicating the dripping state. This electrical signal is sent to the second signal conversion circuit 9 within the measuring box 5, where it is converted, amplified, and filtered to obtain a monitoring signal characterizing the cooling water dripping state.

[0031] In one specific embodiment, the vibration sensor 6 is installed on the steel beam body, support structure, or key vibration measurement location of the equipment mounting 7. The vibration sensor 6 is used to sense the mechanical vibration transmitted to the equipment mounting 7 during equipment operation and convert the mechanical vibration signal into an electrical signal. Preferably, the electrical signal output by the vibration sensor 6 is a sine wave signal. This sine wave signal is input to the third signal conversion circuit 10 in the measurement box 5. The third signal conversion circuit 10 filters, amplifies, and shapes the sine wave signal, and converts it into a square wave signal or other signals suitable for digital acquisition before sending it to the acquisition circuit 11.

[0032] like Figure 1As shown, the measuring box 5 includes a first signal conversion circuit 8, a second signal conversion circuit 9, a third signal conversion circuit 10, a data acquisition circuit 11, a microcontroller 12, and an RS-485 communication circuit 13. The first signal conversion circuit 8 is connected to the temperature sensor 2, the second signal conversion circuit 9 is connected to the water droplet sensor 3, and the third signal conversion circuit 10 is connected to the vibration sensor 6. The data acquisition circuit 11 is connected to the first signal conversion circuit 8, the second signal conversion circuit 9, and the third signal conversion circuit 10, respectively, and is used to receive the conditioned temperature signal, water droplet signal, and vibration signal, and convert these signals into digital signals.

[0033] In one specific embodiment, the acquisition circuit 11 includes an analog-to-digital converter (ADC). The signal processed by the first signal conversion circuit 8, the second signal conversion circuit 9, and the third signal conversion circuit 10 is input to the ADC, converted into a digital quantity, and then transmitted to the microcontroller 12. The microcontroller 12 serves as the control and computation core of the measuring box 5, receiving temperature data, water droplet state data, and vibration data, and performing a comprehensive judgment on the aforementioned multi-parameter data based on a built-in diagnostic algorithm.

[0034] In one specific embodiment, the measuring box 5 also receives the rotational speed signal of the equipment. This rotational speed signal can be directly connected to the measuring box 5 from the equipment side, and the measuring box 5 collects, processes, or participates in comprehensive judgment. The microcontroller 12 can perform fusion analysis based on at least two parameters among temperature, water droplet state, vibration amplitude, and rotational speed to obtain the operational health status of the equipment rack 7. When any monitored parameter exceeds a preset safety threshold, or when multiple parameters show an abnormal trend, the microcontroller 12 generates a corresponding alarm signal and identifies the type of abnormal monitored parameter.

[0035] In one specific embodiment, the RS-485 communication circuit 13 is connected to the microcontroller 12 and is used to upload the data output by the microcontroller 12 to the upper-level monitoring system 14. The upper-level monitoring system 14 can be a DCS system, a PLC system, or other industrial monitoring system. The data uploaded by the measuring box 5 through the RS-485 communication circuit 13 includes, but is not limited to, temperature measurement values, water droplet status, vibration data, rotational speed data, trend information, alarm signals, and abnormal parameter location information. After receiving the above data, the upper-level monitoring system 14 can perform centralized display, recording, alarm prompts, or linkage control.

[0036] In one specific embodiment, multiple temperature sensors 2, water droplet sensors 3, and vibration sensors 6 can be configured. Multiple temperature sensors 2 are respectively installed at multiple wiring positions on the power busbar 1; multiple water droplet sensors 3 are respectively installed at joints or leak-prone locations on multiple cooling water pipes 4; and multiple vibration sensors 6 are respectively installed at one or more key vibration measurement positions on the equipment mounting 7. Through the distributed arrangement of multiple sensors, the monitoring coverage can be expanded, and the accuracy of anomaly location can be improved.

[0037] This embodiment also provides a multi-parameter online monitoring method for equipment mounting. After the system is powered on, the measuring box 5, temperature sensor 2, water droplet sensor 3, vibration sensor 6, and RS-485 communication circuit 13 are first initialized. After initialization, temperature sensor 2 collects the temperature signal of power bus 1, water droplet sensor 3 collects the dripping signal of cooling water pipe 4, vibration sensor 6 collects the vibration signal of equipment mounting 7, and measuring box 5 synchronously receives the above-mentioned multi-parameter monitoring signals.

[0038] Subsequently, the measuring box 5 conditions the temperature signal, water droplet signal, and vibration signal through the first signal conversion circuit 8, the second signal conversion circuit 9, and the third signal conversion circuit 10, respectively, and performs analog-to-digital conversion through the acquisition circuit 11. The converted digital signal is transmitted to the microcontroller 12, which performs comprehensive analysis on the temperature data, vibration data, water droplet state data, and optional rotation speed data.

[0039] When the microcontroller 12 determines that all monitoring data do not exceed the preset safety threshold and there is no abnormal trend, the system records the collected data and uploads the real-time monitoring data to the upper-level monitoring system 14 via the RS-485 communication circuit 13. When the microcontroller 12 determines that any monitoring parameter exceeds the preset safety threshold or determines that there is an abnormal trend, the microcontroller 12 generates an alarm signal and locates the type of abnormal parameter; subsequently, the real-time monitoring data, alarm signal, and abnormal parameter location information are uploaded to the upper-level monitoring system 14 via the RS-485 communication circuit 13 to prompt operation and maintenance personnel to handle the situation promptly.

[0040] After completing one data acquisition, judgment, and upload process, the system determines whether to continue monitoring. If the system is in continuous monitoring mode, it returns to the multi-parameter synchronous acquisition step and repeatedly executes the signal acquisition, signal conditioning, data judgment, and data upload process; if a stop command is received or the system is powered off, the monitoring process ends.

[0041] The present application has been described in detail above with reference to the accompanying drawings and embodiments. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application. All content not described in detail in this application can be derived from existing technology.
