Description

Technical Field

[0001] This application relates to the field of lubrication monitoring technology for gas separation production equipment, and in particular to an online intelligent oil monitoring device. Background Technology

[0002] Currently, the monitoring of lubricating oil in gas separation production equipment mainly relies on manual periodic sampling and laboratory analysis. This method is lagging and cannot reflect the lubricating oil status in real time.

[0003] With the development of industrial automation, some enterprises have begun to adopt centralized online monitoring systems. However, these systems typically employ a single sensor and central processing unit architecture, resulting in data transmission delays and low system reliability. To address these issues, an online intelligent monitoring device for oil products is proposed. Utility Model Content

[0004] The purpose of this application is to provide an online intelligent oil monitoring device that enables real-time online monitoring of lubricating oil status, improves the reliability and fault tolerance of the monitoring system, and solves the problems in the background technology.

[0005] The online intelligent monitoring device for oil products provided in this application adopts the following technical solution: An online intelligent monitoring device for oil products includes a sensor assembly, a local analysis assembly, a regional communication assembly, a monitoring center server, and a user terminal computer connected in sequence. The sensor assembly includes a mounting plate and a cylindrical base fixed to one side of the mounting plate. A viscosity sensor, an impurity sensor, and a temperature sensor are provided on the cylindrical base. An external port is provided at the end of the cylindrical base away from the mounting plate. The viscosity sensor, impurity sensor, and temperature sensor are all electrically connected to the external port.

[0006] The local analysis component includes a local oil analyzer body, which is equipped with a transmission interface adapted to an external port. The local oil analyzer body internally includes a signal conditioning module, a data processing unit, and a communication interface. The signal conditioning module is electrically connected to the transmission interface and the data processing unit, respectively, and the data processing unit is connected to the communication interface.

[0007] The regional communication component includes a regional communication host, which is equipped with a CAN bus interface adapted to the communication interface. The regional communication host has a data buffer module inside, and the CAN bus interface is electrically connected to the data buffer module. By adopting the above technical solution, the sensor component can collect multiple parameters of the lubricating oil in real time and transmit them to the local analysis component through the external port. After being conditioned by the signal conditioning module and processed by the data processing unit, the data is transmitted to the regional communication component through the communication interface and then temporarily stored through the data caching module, forming a distributed data transmission link. This avoids the problem of single point of failure in centralized systems and realizes real-time online monitoring of the lubricating oil status. At the same time, the hierarchical connection structure of each component improves the reliability and fault tolerance of the system.

[0008] Preferably, the mounting plate has multiple mounting holes, which are evenly distributed around the circumference of the mounting plate. The sensor assembly is detachably connected to the external device's lubricating oil test point through the mounting holes.

[0009] By adopting the above technical solution, the uniform distribution of multiple mounting holes can securely fix the sensor assembly to the external equipment's lubrication oil test point. The detachable connection design facilitates flexible installation and subsequent maintenance according to the test point location of different equipment, avoiding the problem that traditional fixing methods are difficult to adapt to different equipment and enhancing the system's versatility.

[0010] Preferably, one side of the mounting plate is provided with a limiting groove that matches the lubricating oil test point, and a low-temperature resistant sealing ring is provided at the opening of the limiting groove.

[0011] By adopting the above technical solutions, the limiting groove can be precisely matched with the structure of the lubricating oil test point, ensuring the accuracy of the sensor component installation position and avoiding displacement caused by equipment vibration; the low-temperature resistant sealing ring can enhance the sealing performance of the installation point, prevent lubricating oil leakage, and adapt to the low-temperature environment of gas production plants, avoiding sealing failure caused by low temperature, thus solving the problem of poor sealing performance of existing monitoring devices in low-temperature environments.

[0012] Preferably, the bottom of the local oil analyzer body is provided with a buffer pad, and positioning seats are fixedly connected to the four corners of the bottom surface of the local oil analyzer body.

[0013] By adopting the above technical solutions, the buffer pad can absorb the vibration generated by the operation of the equipment, reduce the impact of vibration on the internal signal conditioning module, data processing unit and other components of the local oil analyzer, and improve the stability of data processing; the positioning seat can make the local oil analyzer body firmly installed in the designated position, avoid displacement, and enhance the reliability of the device in the vibration environment.

[0014] Preferably, heat dissipation mesh plates are installed on both side walls of the local oil analyzer body, and a display is installed on the top surface of the local oil analyzer body, which is electrically connected to the data processing unit.

[0015] By adopting the above technical solution, the heat dissipation mesh can dissipate the heat generated by the internal components of the local oil analyzer in a timely manner, avoiding the impact of high temperature on the performance of the signal conditioning module and data processing unit; the display can display the monitoring results output by the data processing unit in real time, making it easy for on-site personnel to intuitively understand the lubricating oil status, solving the problem of traditional devices lacking on-site real-time viewing function, and improving the ease of operation.

[0016] Preferably, there are multiple CAN bus interfaces, and each CAN bus interface is connected to a communication interface of a local analysis component.

[0017] By adopting the above technical solution, multiple CAN bus interfaces can be connected to multiple local analysis components simultaneously, enabling the aggregation of multiple sets of sensor data and forming a distributed monitoring architecture. When a CAN bus interface fails, only the data transmission of the corresponding local analysis component is affected, avoiding the problem of the entire system being paralyzed due to a centralized interface failure, and improving the system's fault tolerance and scalability.

[0018] Preferably, the regional communication host is connected to the monitoring center server, and the monitoring center server is connected to the user terminal computer.

[0019] By adopting the above technical solution, the regional communication component can transmit the aggregated data to the monitoring center server for centralized processing, and then the monitoring center server will feed the results back to the user's computer, forming a complete "collection-processing-feedback" link. This ensures that the lubricating oil status data is transmitted to the user in real time, solves the problem of lag in traditional manual sampling, and realizes online real-time monitoring.

[0020] Preferably, the user terminal computer is connected to the monitoring center server via a network cable or wireless module, and the user terminal computer has an interface adapted to the monitoring center server on its casing.

[0021] By adopting the above technical solutions, the multiple connection methods of wired or wireless modules allow user computers to flexibly adapt to different network environments. The compatible interfaces ensure stable connections, making it easy for users to choose the appropriate connection method according to the network layout of the gas production plant. This avoids the problem that a single connection method is difficult to adapt to complex industrial environments and enhances the adaptability of the system.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This online intelligent oil monitoring device employs a distributed architecture formed by the hierarchical connection of sensor components, local analysis components, regional communication components, a monitoring center server, and user-end computers. Compared to existing technologies, it effectively solves the problems of lag in manual sampling and single-point failure in centralized systems.

The sensor assembly 1 includes a mounting plate 101 and a cylindrical base 102 fixed to one side of the mounting plate 101. A viscosity sensor 103, an impurity sensor 104, and a temperature sensor 105 are mounted on the cylindrical base 102. An external port 106 is located at the end of the cylindrical base 102 furthest from the mounting plate 101. The viscosity sensor 103, impurity sensor 104, and temperature sensor 105 are all electrically connected to the external port 106. The mounting plate 101 has multiple mounting holes 107 evenly distributed along its circumference. The sensor assembly 1 is detachably connected to the external device's lubricating oil measurement point through the mounting holes 107. The uniform distribution allows the sensor assembly 1 to be firmly fixed to the lubricating oil test point of the external equipment. The detachable connection design facilitates flexible installation and subsequent maintenance according to the test point location of different equipment, avoiding the problem of traditional fixing methods being difficult to adapt to different equipment, and enhancing the versatility of the system. One side of the mounting plate 101 has a limiting groove 108 adapted to the lubricating oil test point. The groove opening of the limiting groove 108 is provided with a low temperature resistant sealing ring 109. The limiting groove 108 can be precisely adapted to the structure of the lubricating oil test point, ensuring the accuracy of the installation position of the sensor assembly 1 and avoiding displacement caused by equipment vibration. The low temperature resistant sealing ring 109 can enhance the sealing performance of the installation point, prevent lubricating oil leakage, and adapt to the low temperature environment of the gas production plant, avoiding sealing failure caused by low temperature, thus solving the problem of poor sealing performance of existing monitoring devices in low temperature environments.

[0027] Reference Figure 1 , Figure 3 and Figure 4The local analysis component 2 includes a local oil analyzer body 201. The local oil analyzer body 201 is equipped with a transmission interface 202 adapted to the external port 106. Internally, the local oil analyzer body 201 houses a signal conditioning module 203, a data processing unit 204, and a communication interface 205. The signal conditioning module 203 is electrically connected to the transmission interface 202 and the data processing unit 204, respectively. The data processing unit 204 is connected to the communication interface 205. A buffer pad 207 is located at the bottom of the local oil analyzer body 201, and positioning seats 208 are fixedly connected to the four corners of the bottom surface of the local oil analyzer body 201. The buffer pad 207 absorbs vibrations generated during equipment operation, reducing the impact of vibrations on components such as the signal conditioning module 203 and the data processing unit 204 inside the local oil analyzer body 201. This design improves the stability of data processing. The positioning base 208 ensures that the local oil analyzer body 201 is stably installed in the designated position, preventing displacement and enhancing the reliability of the device in vibration environments. Both side walls of the local oil analyzer body 201 are equipped with heat dissipation mesh plates 209, and the top surface of the local oil analyzer body 201 is equipped with a display 206, which is electrically connected to the data processing unit 204. The heat dissipation mesh plates 209 can dissipate the heat generated by the internal components of the local oil analyzer body 201 in a timely manner, preventing high temperatures from affecting the performance of the signal conditioning module 203 and the data processing unit 204. The display 206 can display the monitoring results output by the data processing unit 204 in real time, making it easy for on-site personnel to intuitively understand the lubricating oil status, solving the problem of traditional devices lacking on-site real-time viewing functions, and improving the ease of operation.

[0028] Example 2: An online intelligent monitoring device for oil products, referring to... Figure 1 , Figure 2 and Figure 3Based on the same concept as Embodiment 1 above, this embodiment proposes a regional communication component 3 including a regional communication host 301. The regional communication host 301 is equipped with a CAN bus interface 302 adapted to the communication interface 205. The regional communication host 301 has a data cache module 303 inside. The CAN bus interface 302 is electrically connected to the data cache module 303. There are multiple CAN bus interfaces 302, and each CAN bus interface 302 is connected to a corresponding communication interface 205 of a local analysis component 2. Multiple CAN bus interfaces 302 can connect to multiple local analysis components 2 simultaneously, realizing the aggregation of multiple sets of sensor data and forming a distributed monitoring architecture. When the CAN bus interface 302 fails, it only affects the data transmission of the corresponding local analysis component 2, avoiding the problem of the entire system being paralyzed due to a centralized interface failure, and improving the fault tolerance and scalability of the system. The regional communication host 301 is communicatively connected to the monitoring center server 4. The monitoring center server 4 has an internal... The system includes a database module and a data analysis module for storing and processing all monitoring data. The monitoring center server 4 communicates with the user terminal computer 5. The regional communication component 3 transmits the aggregated data to the monitoring center server 4 for centralized processing, and then the monitoring center server 4 feeds the results back to the user terminal computer 5, forming a complete "collection-processing-feedback" link. This ensures that lubricating oil status data is transmitted to the user in real time, solving the problem of lag in traditional manual sampling and realizing online real-time monitoring. The user terminal computer 5 connects to the monitoring center server 4 via a network cable or wireless module. The user terminal computer 5 has an interface adapted to the monitoring center server 4 on its casing. The multiple connection methods of network cable or wireless module allow the user terminal computer 5 to flexibly adapt to different network environments. The adapted interface ensures a stable connection, allowing users to choose the appropriate connection method according to the network layout of the gas production plant. This avoids the problem that a single connection method is difficult to adapt to complex industrial environments and enhances the system's adaptability.

[0029] The implementation principle of this application embodiment is as follows: The sensor assembly 1 is fixed to the external device lubricating oil test point through the mounting hole 107 and the limiting groove 108 of the mounting plate 101. The viscosity sensor 103, impurity sensor 104, and temperature sensor 105 on the cylindrical base 102 are in direct contact with the lubricating oil and collect parameters such as viscosity, impurity content, and temperature of the lubricating oil in real time. These parameters are processed by the internal circuit of the sensor and output through the external port 106. At this time, the low temperature resistant sealing ring 109 ensures the sealing of the installation point and avoids lubricating oil leakage and the influence of low temperature environment. The parameter signal enters the local oil analyzer body 201 through the external port 106 and the transmission interface 202 of the local analysis component 2. The signal conditioning module 203 first filters and amplifies the raw signal to eliminate interference and ensure signal accuracy. The conditioned signal is then transmitted to the data processing unit 204 for analysis and processing, converting it into identifiable monitoring data. Simultaneously, the data processing unit 204 transmits the data to the display 206 for on-site viewing. The buffer pad 207 and positioning seat 208 reduce the impact of vibration on the processing, while the heat dissipation mesh 209 ensures stable operation of the internal components. The processed data is transmitted through the communication interface 205 to the CAN bus interface 302 of the regional communication component 3. Data from multiple local analysis components 2 are aggregated to the regional communication host 301 via their respective communication interfaces 205 and temporarily stored by the data cache module 303 to prevent data loss. Subsequently, the regional communication host 301 transmits the aggregated data to the monitoring center server 4 for in-depth analysis and storage. The final analysis results are then sent to the user terminal computer 5 via the communication link. Users can obtain lubricating oil status information in real time through the user terminal computer 5, realizing online monitoring of the entire process from parameter acquisition, processing, aggregation to result feedback.
