[0028] To address the problems mentioned in the background art, this application proposes a monitoring subsystem for pipeline instruments. Figure 1A schematic diagram of the composition of a pipeline instrumentation monitoring subsystem provided in this embodiment of the present invention is shown below. Figure 1 The pipeline instrumentation monitoring subsystem 100 includes an environmental sensing module 101, a pipeline sensing module 102, a communication module 103, a server 104, and a monitoring workstation 105. The environmental sensing module 101 includes various environmental sensors 106, which are installed in the production environment. The pipeline sensing module 102 includes various pipeline status sensors 107, which are installed in the production equipment and / or production pipeline system. The server 104 is communicatively connected to the environmental sensors 106 and the pipeline status sensors 107 via the communication module 103. The monitoring workstation 105 is communicatively connected to the server 104.

[0029] Specifically, the environmental sensing module 101 is a crucial component for real-time sensing and acquisition of relevant parameters of the factory environment. It includes multiple environmental sensors 106 installed throughout the production environment. The environmental sensors 106 can perform real-time measurement and data acquisition of various physical and chemical environmental parameters in the factory environment, providing foundational data for subsequent analysis and decision-making. For example, the environmental parameters acquired by the environmental sensors 106 may include target gas concentration, temperature, humidity, air pressure, light intensity, air quality (including harmful gas concentrations), and noise levels. The environmental sensors 106 may include at least one of the following: a nitrogen concentration sensor, an oxygen concentration sensor, a humidity transmitter, a temperature transmitter, and a pressure sensor.

[0030] The pipeline status sensing module is a key component for real-time monitoring and acquisition of pipeline operating conditions. It includes multiple pipeline status sensors 107 installed at various locations on the production equipment or pipeline.

For example, the communication module 103 may include a serial port server and a switch.

[0032] Monitoring workstation 105 refers to a collection of devices used to monitor the factory's production environment, production equipment, and production pipeline system.

[0033] Server 104 is the core component of the pipeline instrumentation monitoring subsystem 100, undertaking key tasks such as data processing, storage, management, forwarding, and coordination between modules. For example, during the operation of the pipeline instrumentation monitoring subsystem 100, various modules generate a large amount of data, such as equipment operating parameters, environmental monitoring data, and production process data. Server 104 can be equipped with a large-capacity data storage device configured as a non-volatile storage device for real-time monitoring data and historical data.

Server 104 can also be equipped with multiple network interfaces to receive data from various sensor modules in real time and forward it to the monitoring workstation 105. The high-speed processor also performs data parsing, filtering, and calculations, such as calibrating and normalizing the raw data collected by various sensors, making it meaningful and usable information. It should be noted that the management algorithms, data processing methods and other software methods involved in server 104 in this application are all prior art. This application only protects the components of the system and the connection relationships between the components.

[0034] The pipeline instrumentation monitoring subsystem provided in this embodiment includes an environmental sensing module, a pipeline sensing module, a communication module, a server, and a monitoring workstation. The environmental sensing module includes multiple environmental sensors installed in the production environment. The pipeline sensing module includes multiple pipeline status sensors installed in the production equipment and / or production pipeline system.

[0035] Optionally, Figure 2 This is a schematic diagram of another pipeline instrumentation monitoring subsystem provided in an embodiment of the present invention. Based on the foregoing embodiments, refer to... Figure 2 The communication module 103 includes a serial port server 201 and a data acquisition gateway 202 corresponding to the serial port server 201. The serial port server 201 is connected to its corresponding environmental sensor 106 and / or its corresponding pipeline sensing module 102 via an RS485 serial bus; the serial port server 201 is also connected to its corresponding data acquisition gateway 202 via an Ethernet communication connection. The data acquisition gateway 202 is connected to the server 104 via a message queue telemetry transmission protocol (also known as the MQTT protocol).

[0036] Specifically, the serial port server 201 is a network device that converts the RS485 signal of a serial port device into an Ethernet signal, enabling the serial port device to connect to a downstream Ethernet network. This allows for remote management of the serial port device and bidirectional data transmission between the serial port device and the server 104. The serial port device in this application includes at least an environmental sensor 106, a pipeline sensor, and a controller for the production equipment. When there are a large number of environmental sensors 106 and pipeline status sensors 107, multiple serial port servers 201 can be configured. One serial port server 201 corresponds to at least one environmental sensor 106 and / or at least one pipeline status sensor 107. For example, two serial port servers 201 can be configured: one serial port server 201 connected to each of the environmental sensors 106, and the other serial port server 201 connected to each of the pipeline status sensors 107.

[0037] The data acquisition gateway 202 is a device used for acquiring, processing, and transmitting data. It can collect data from environmental sensors 106, pipeline sensors, and the controller of production equipment, convert this data into a standard format, and transmit it to the server 104 for further analysis and processing. When there are a large number of environmental sensors 106 and pipeline status sensors 107, multiple data acquisition gateways 202 can be configured, with each data acquisition gateway 202 connected to at least one serial port server 201.

[0038] The pipeline instrumentation monitoring subsystem provided in this embodiment includes a communication module comprising a serial port server and a corresponding data acquisition gateway. The serial port server is connected to its corresponding environmental sensors and / or their corresponding pipeline sensing modules via an RS485 serial bus; it is also connected to its corresponding data acquisition gateway via Ethernet. The data acquisition gateway and server are connected via a message queue telemetry transmission protocol, enabling communication between the server and sensors. This results in fast data transmission speeds, facilitating remote management of the factory environment and production equipment, and improving factory safety and monitoring efficiency.

[0039] Optionally, Figure 3 This is a schematic diagram illustrating the composition of another pipeline instrumentation monitoring subsystem provided in this embodiment of the present invention. Based on the foregoing embodiments, referencing... Figure 3 The pipeline instrumentation monitoring subsystem 100 also includes an early warning module 301, which includes a mobile early warning terminal 303 and an audible and visual alarm 302. The mobile early warning terminal 303 is wirelessly connected to the server 104; the audible and visual alarm 302 is located in the production environment and / or at the monitoring workstation 105 and is wirelessly or wiredly connected to the server 104. The monitoring workstation 105 includes at least one of a handheld computer and a display screen.

[0040] Specifically, the early warning module 301 is a key functional component used to monitor various parameters in the pipeline system in real time and issue timely alarms when abnormalities or potential risks are detected, preventing equipment damage, production interruptions, or safety accidents. The mobile early warning terminal 303 is wirelessly connected to the server 104, and this wireless communication connection can be via Wi-Fi, Bluetooth, 4G, 5G, or cellular network. The mobile early warning terminal 303 can alert the user to abnormal environmental or status parameters based on early warning signals such as SMS messages, application software push notifications, or emails sent by the server 104. For example, the mobile early warning terminal 303 may include a mobile phone, tablet, or laptop. The audible and visual alarm 302 is installed at the production site and communicates with the server 104. It can alert on-duty personnel to abnormal environmental or status parameters by emitting alarm sounds and alarms. For example, the audible and visual alarm 302 includes a string of flashing lights and a speaker. The audible and visual alarm 302 may also include at least three-color warning lights, such as red, yellow, and blue warning lights. The audible and visual alarm 302 can be configured to illuminate different colored warning lights according to the fault probability or severity classification of the monitoring points of the production pipeline system to provide indicative warnings to on-duty personnel.

[0041] The monitoring workstation 105 is a computer workstation used to monitor the factory's production environment, production equipment, and related pipelines. It is equipped with a high-performance computer or processor, as well as dedicated monitoring software, for real-time display, storage, and processing of sampled data from sensors, cameras, and instruments at the production site. For example, the monitoring workstation 105 may include information receiving and processing devices such as computers, and may also include data display devices such as projectors and displays.

[0042] For example, firstly, sensor deployment. Based on the layout of the factory's piping and instrumentation equipment, the location and type of various sensors are determined, such as temperature transmitters, nitrogen concentration sensors, oxygen concentration sensors, flow meter sensors, and liquid level / pressure sensors. Each sensor is connected to a serial port server 201 via a 485 interface. One serial port server 201 can connect to multiple sensor devices, and multiple serial port servers 201 can be placed in different areas. Secondly, data acquisition and network connection. Data acquisition gateway 202 connects to serial port server 201 via TCP / IP Ethernet to perform data acquisition from the piping and instrumentation equipment. The network connection layer can deploy multiple data acquisition gateways 202 to connect to serial port server 201, reducing the data acquisition load on a single gateway and achieving balanced data acquisition workload. Thirdly, big data processing. The network connection layer has already implemented the data acquisition function. The raw data collected by the data acquisition gateway 202 is pushed to the big data processing platform mounted on server 104 via the MQTT protocol. In this embodiment, the big data processing platform can be Hadoop. Server 104 cleans, classifies, and analyzes the collected raw data, storing it in a data storage device in both real-time and historical data formats. The data storage device employs a dual-machine hot standby method to ensure data security. When anomalies occur during data analysis, such as temperature or pressure approaching alarm thresholds, server 104 pushes the anomaly information to the early warning module 301. Firstly, when an alarm occurs, the early warning module 301 can alert staff via audible and visual alarms at the factory production site or push notifications from a mobile application, allowing for rapid location of the alarm fault and its cause, thus preventing further alarms. Secondly, it provides visualized monitoring. Monitoring workstation 105 uses a large visual screen to display the real-time operating status of various pipeline instruments and equipment within the factory, and provides historical data retrieval functions for analyzing the causes of fault alarms. Finally, all the aforementioned data and work logs can be uploaded to a network cloud platform to ensure efficient and stable system operation.

[0043] The pipeline instrumentation monitoring subsystem provided in this embodiment is equipped with an early warning module, which includes a mobile early warning terminal and an audible and visual alarm. The mobile early warning terminal is wirelessly connected to the server; the audible and visual alarm is installed in the production environment and / or monitoring workstation and is wirelessly or wiredly connected to the server; the audible and visual alarm can illuminate indicator lights of corresponding colors according to the probability or severity of the fault. A blue indicator light indicates a low probability or low severity alarm that does not require action; yellow indicates a medium probability or medium severity alarm that requires action; and red indicates a high probability or high severity alarm that requires emergency action. Workers can determine the level of fault based on the color of the indicator light and perform corresponding fault handling work, realizing real-time early warning of environmental and status parameters, shortening the response time of workers, and further improving production safety.
