Description

Technical Field

[0001] This invention relates to the field of remote monitoring technology, specifically to a wireless pressure parameter remote monitoring system compatible with multiple terminals. Background Technology

[0002] In oil, gas, chemical and general industrial sites, the internal pressure of pipelines or containers is a core parameter for judging whether the process is abnormal and whether the equipment is reliable. Once the pressure suddenly rises or falls, the operators must make decisions such as stopping the pump, closing the valve or adjusting the medium parameters within minutes. Otherwise, it may cause leakage, explosion or environmental accidents. Therefore, continuously and accurately obtaining pressure data is a basic prerequisite for ensuring production safety and protecting personnel, equipment and the environment.

[0003] Traditionally, hundreds of meters of cable are laid between the pressure measurement point and the control room to send the analog signal from the pressure transmitter to a fixed secondary instrument. The duty personnel manually record the data on paper every two hours. In case of night, rain, snow, or muddy weather, it is easy to miss or misrecord the data. When the equipment is relocated, the cable needs to be disassembled, coiled, and reconnected repeatedly, which increases the relocation time and adds procedures to the tight preparation work. At the same time, if the management personnel want to view the data, they must go to the control room in person, which makes it impossible to monitor the operating conditions in real time. Historical records are piled up in cardboard boxes for a long time, and tracing them often requires searching through paper tapes for a long time, which is inefficient and easy to lose. Therefore, in view of the above problems, a wireless pressure parameter remote monitoring system compatible with multiple terminals is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a wireless pressure parameter remote monitoring system that is compatible with multiple terminals, so as to solve the problems of slow relocation, difficult viewing, and easy data loss of traditional wired solutions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-terminal compatible wireless pressure parameter remote monitoring system includes an external detection subsystem and an observation subsystem. The external detection subsystem consists of a remote transmission detection unit, a data acquisition and transmission assembly, and a mobile power supply. The remote transmission detection unit is a remote vibration-resistant pressure gauge, used to install on the equipment requiring pressure measurement, and converts the pressure into a standard electrical signal. The data acquisition and transmission assembly has a built-in transmitting antenna, which is connected to the remote transmission detection unit via a data cable. It performs analog-to-digital conversion on the received electrical signal, encapsulates it, and transmits it outward through the transmitting antenna. The mobile power supply is a replaceable lithium battery pack, used to power the data acquisition and transmission assembly via a power cable. The observation subsystem consists of a data receiving and conversion assembly, a digital display recording cloud transmission assembly, and well site mains power. The data receiving and conversion assembly has a built-in receiving antenna for receiving wireless signals emitted by the data acquisition and transmission assembly of the external detection subsystem and demodulating them into data frames. The digital display recording cloud transmission assembly is connected to the data receiving and conversion assembly via a data cable. It performs engineering quantity conversion, alarm judgment, curve buffering, and local storage on the data frames, and simultaneously pushes the data to the cloud via a 4G / 5G network, enabling real-time viewing and historical tracing for multiple user terminals. The well site mains power continuously supplies power to the data receiving and conversion assembly and the digital display recording cloud transmission assembly via a power cable, ensuring uninterrupted 24-hour operation of the observation terminal.

[0006] Preferably, the digital display recording cloud transmission assembly consists of a functional application display layer, function buttons, and infrastructure. The functional application display layer includes a digital display interface, a cyclic display interface, a real-time curve interface, and a function query interface. The digital display interface supports multi-channel simultaneous display in columns, with each column listing the real-time engineering quantity value of the corresponding remote transmission detection unit in large font, allowing for a comprehensive overview of the pressure at each point on-site. It also supports one-click switching to display or hide the original signal value. The cyclic display interface automatically rotates the real-time data of each channel at a set time interval, and the rotation can be manually started and stopped. The real-time curve interface supports multi-channel simultaneous scrolling, that is, synchronously refreshing and scrolling the real-time pressure curves of multiple remote transmission detection units within the same time coordinate. It has zoom, pan, curve hiding, and cursor reading functions, presenting the pressure change trend in real time. The function query interface serves as a menu entry point, allowing access to the historical curve interface, power failure record interface, alarm record interface, operation log interface, data transfer interface, and configuration login interface.

[0007] Preferably, the historical curve interface is used to retrieve and display multi-channel pressure curves for any time period, supporting zooming, recalling, cursor reading, and curve hiding, facilitating post-event analysis and fault tracing. The power failure record interface is used to save and view up to 256 instrument power failure events, recording the power failure time, power-on time, and power failure duration, which cannot be manually modified, providing a time basis for accident accountability. The alarm record interface is used to save and view up to 256 alarm events, including alarm channel, type, status, and start and end time, supporting browsing one by one and quick page turning, facilitating fault statistics. The operation log interface is used to save and view up to 256 key operation records, including operation time and operation events, ensuring that setting changes are traceable. The data transfer interface can automatically pop up after inserting a USB flash drive, allowing for full data transfer, firmware upgrades, and USB flash drive formatting. The configuration login interface is used to enter a password to access the configuration settings interface, with an initial password of 0000, preventing unauthorized personnel from modifying the instrument's core configuration.

[0008] Preferably, the configuration login interface can access the system interface, input interface, alarm interface, communication interface, transmitter interface, and printing interface. The system interface is used to set the date and time, language, login password, recording interval, cold junction compensation, and factory reset parameters. The input interface is used to configure parameters such as channel tag number, signal type, range, decimal point, filtering, disconnection handling, and small signal cutoff. The alarm interface is used to set the upper and lower limits, upper upper limit, lower lower limit alarm values, hysteresis, delay, and relay delay for each channel. The communication interface is used to set the address, baud rate, checksum, and floating-point byte exchange order. The transmitter interface is used to specify the source channel of the transmitter output channel. The printing interface is used to set the printing interval, printing direction, and printing format.

[0009] Preferably, the function keys include a left key, a right key, an up key, a down key, a C key, and an Ent key, used to control the function application display layer. The left and right keys are used to switch the display screen, switch parameters, or modify data. The up and down keys are used to switch menu items. The Ent key is used to confirm the operation, edit data, or input text. The C key is used to return to or cancel the current operation and can start or stop printing.

[0010] Preferably, the infrastructure includes a data receiving unit, a data processing unit, a recording and storage unit, a display unit, and a data transmitting unit. The data receiving unit receives data frames from the data receiving and conversion assembly via a data cable and performs frame verification and caching. The data processing unit performs engineering quantity conversion, alarm discrimination, curve interpolation, and Modbus register mapping on the verified data frames to generate standardized data that can be displayed, stored, and uploaded. The recording and storage unit stores the standardized data, forming a timestamped historical file that supports data retention even when power is off and cyclic storage. The display unit is a display screen that, in conjunction with the functional application display layer, displays the standardized data. The data transmitting unit encrypts and pushes the standardized data to the cloud via a 4G / 5G mobile network, enabling simultaneous access by multiple user terminals, including computers and mobile phones.

[0011] Compared with the prior art, the beneficial effects of the present invention are: In this invention, through the establishment of external detection subsystems and observation subsystems, the external detection subsystem can wirelessly transmit the pressure signal of the pressure-tested equipment to the observation subsystem in the duty room, eliminating the need for laying long-distance cables. This shortens relocation and installation time, reduces cable costs and maintenance workload. The observation subsystem can centrally complete data parsing, local storage, cloud push, and multi-terminal display, achieving wireless real-time synchronization of data at three levels: pressure testing point, duty room, and user terminal, improving anomaly response speed. The dual-power zoned power supply mode ensures flexible movement of the detection end and continuous online operation of the observation end. Combined with large-capacity local storage and encrypted cloud transmission, it ensures that data is not lost during network interruption and is uninterrupted after recovery. This constructs a multi-terminal wireless remote pressure monitoring system with simple wiring, stable operation, and convenient viewing, solving the problems of slow relocation, difficult viewing, and easy data loss in traditional wired solutions.

Detailed Implementation

[0013] Please see Figure 1-18 The present invention provides a technical solution: A multi-terminal compatible wireless pressure parameter remote monitoring system includes an external detection subsystem and an observation subsystem. The external detection subsystem consists of a remote transmission detection unit, a data acquisition and transmission assembly, and a mobile power supply. The remote transmission detection unit is a remote vibration-resistant pressure gauge, installed on the equipment requiring pressure measurement, and converts the pressure into a standard electrical signal. The data acquisition and transmission assembly has a built-in transmitting antenna, connects to the remote transmission detection unit via a data cable, performs analog-to-digital conversion on the received electrical signal, encapsulates it, and transmits it outward through the transmitting antenna. The mobile power supply is a replaceable lithium battery pack, used to power the data acquisition and transmission assembly via a power cable. The observation subsystem consists of a data receiving and conversion assembly, a digital display recording cloud transmission assembly, and well site mains power. The data receiving and conversion assembly has a built-in receiving antenna to receive wireless signals emitted by the data acquisition and transmission assembly of the external detection subsystem and demodulate them into data frames. The digital display recording cloud transmission assembly is connected to the data receiving and conversion assembly via a data cable. It performs engineering quantity conversion, alarm judgment, curve buffering, and local storage on the data frames. At the same time, it pushes the data to the cloud via a 4G / 5G network, enabling real-time viewing and historical tracing for multiple user terminals. The well site mains power continuously supplies power to the data receiving and conversion assembly and the digital display recording cloud transmission assembly via a power cable, ensuring uninterrupted 24-hour operation of the observation terminal.

[0014] The digital display recording cloud transmission assembly consists of a functional application display layer, function buttons, and infrastructure. The functional application display layer includes a digital display interface, a cyclic display interface, a real-time curve interface, and a function query interface. The digital display interface supports multi-channel simultaneous display in columns, with each column listing the real-time engineering quantity values ​​of the corresponding remote transmission detection unit in large font. This allows for a comprehensive overview of the pressure at each point on-site, and supports one-click switching to display or hide the original signal values. The cyclic display interface automatically rotates the real-time data of each channel at set time intervals, and the rotation can be manually started and stopped. The real-time curve interface supports multi-channel simultaneous scrolling, meaning it synchronously refreshes and scrolls the real-time pressure curves of multiple remote transmission detection units within the same time coordinate. It features zoom, pan, curve hiding, and cursor reading functions, presenting real-time pressure change trends. The query interface serves as a menu entry point, providing access to the historical curve interface, power failure record interface, alarm record interface, operation log interface, data transfer interface, and configuration login interface. This setting allows the functional application display layer to showcase "single-point values, multi-point rotation, dynamic curves, and menu entry points" through display units, enabling on-site personnel to quickly grasp the pressure of all measuring points. One-click switching, zooming readings, and cursor tracking can be directly performed via function keys, eliminating the need for an external keyboard or complex commands. This improves inspection efficiency, reduces learning costs, and achieves a simple "what you see is what you get" human-machine interaction. It provides a unified entry point for subsequent data export, alarm tracing, and parameter configuration, making the overall machine operation logic clear, fast, and less prone to misoperation. The historical curve interface is used to recall and... Displays multi-channel pressure curves for any time period, supporting zooming, rewinding, cursor reading, and curve hiding for convenient post-event analysis and fault tracing. The power failure log interface saves and views up to 256 instrument power failure events, recording power failure time, power-on time, and power failure duration. This data cannot be manually modified, providing a temporal basis for accident investigation. The alarm log interface saves and views up to 256 alarm events, including alarm channel, type, status, and start and end times, supporting sequential browsing and quick page turning for easy fault statistics. The operation log interface saves and views up to 256 key operation records, including operation time and events, ensuring traceability of setting changes. The data transfer interface automatically pops up after inserting a USB drive, allowing for full data transfer and firmware upgrades. The USB flash drive is formatted, and the configuration login interface is used to enter a password to access the configuration settings interface. The initial password is 0000 to prevent unauthorized personnel from modifying the core instrument configuration. This setting enables the four interfaces of historical curves, power failure records, alarm records, and operation logs to form a complete "black box" traceability chain. Any pressure abnormality, power interruption, or parameter modification leaves a timestamped electronic evidence that cannot be tampered with. The USB flash drive is plug-and-play, allowing data forensics or firmware upgrades to be completed on-site without a computer, shortening accident analysis time. The configuration login adds an access control to the above functions, preventing misoperation or malicious modification. Thus, from recording, exporting, to permissions, it achieves "post-event traceability, data forensics, and controllable operation," comprehensively improving equipment security and operation and maintenance efficiency.The configuration login interface can access the system interface, input interface, alarm interface, communication interface, transmitter interface, and printing interface. The system interface is used to set the date and time, language, login password, recording interval, cold junction compensation, and restore factory settings. The input interface is used to configure parameters such as channel tag number, signal type, range, decimal point, filtering, disconnection handling, and small signal cutoff. The alarm interface is used to set the upper and lower limits, upper upper limit, and lower lower limit alarm values ​​for each channel, as well as hysteresis, delay, and relay delay. The communication interface is used to set the address, baud rate, parity, and floating-point byte exchange order. The transmitter interface is used to specify the source channel for the transmitter output channel. The printing interface is used to set the printing interval, printing direction, and printing format. This configuration allows the login interface to manage six major categories of parameters—system, input, alarm, communication, transmission, and printing—all under a single key. A single login allows for complete setting of all rules from sampling to output, avoiding omissions caused by scattered menus. Each interface is independent yet logically connected, ensuring that critical information such as range, alarm, communication, and transmission is configured correctly in one go, reducing the time spent on repeated logins and confirmations. Access control prevents unauthorized personnel from arbitrarily modifying core parameters, improving configuration efficiency and ensuring operational security, achieving a rapid configuration experience of "login once, set globally, lock securely." Function keys include left, right, up, down, C, and Ent keys for... The function application is controlled via a display layer. The left and right arrow keys switch between display screens, change parameters, or modify data; the up and down arrow keys switch menu items; the Enter key confirms operations, edits data, or inputs text; and the C key returns to or cancels the current operation and can start or stop printing. This setup arranges the function keys in a six-key layout (left, right, up, down, C, Enter), forming a complete "browse-confirm-exit" loop: the left and right arrow keys allow for quick navigation between interfaces and cursor movement; the up and down arrow keys select menu items and increment / decrement values; the Enter key confirms, enters editing mode, and initiates text input; and the C key returns to the previous level or cancels the current action. No external keyboard or mouse is required. Even with gloves on, on-site personnel can complete all display calls, parameter modifications, and data printing with one hand, significantly reducing learning costs and the probability of misoperation. The infrastructure includes a data receiving unit, a data processing unit, a recording and storage unit, a display unit, and a data transmitting unit. The data receiving unit receives data frames from the data receiving and conversion assembly via a data cable and performs frame verification and caching. The data processing unit performs engineering quantity conversion, alarm discrimination, curve interpolation, and Modbus register mapping on the verified data frames to generate standardized data that can be displayed, stored, and uploaded. The recording and storage unit stores the standardized data, forming a timestamped historical file that supports data retention without loss and cyclic storage.The display unit is a screen that, in conjunction with the functional application display layer, displays standardized data. The data transmission unit is used to encrypt and push standardized data to the cloud via 4G / 5G mobile networks, enabling simultaneous access by multiple user terminals, including computers and mobile phones. This setup allows the infrastructure to complete the entire data lifecycle management in one go through a five-level pipeline of "receiving-processing-storage-displaying-transmitting." The data receiving unit ensures reliable data sources, the data processing unit transforms data frames into usable engineering quantities and simultaneously generates standardized data, the storage unit stores standardized data instantly and ensures it is not lost even when power is off, the display unit visualizes the standardized data locally for inspection personnel to interpret, and the encrypted data transmission unit uploads it to the cloud for real-time access by remote terminals.

[0015] Workflow: The operation of the multi-terminal compatible wireless pressure parameter remote monitoring system is as follows: First, vertically install the remote transmission detection unit (i.e., the remote transmission anti-vibration pressure gauge) at the inlet of the pressure-measuring equipment, and connect its output electrical signal to the data acquisition and transmission assembly via a data cable; then, vertically fix the transmitting antenna of the data acquisition and transmission assembly, power it with a mobile power supply, start the equipment to start sampling, analog-to-digital conversion, and data encapsulation at a 1-second cycle, and transmit wireless signals outward through the transmitting antenna; simultaneously, at the duty room end, raise the receiving antenna of the data receiving and conversion assembly and align it with the direction of the external detection subsystem. After the antenna receives the wireless signal, the data receiving and conversion assembly demodulates it into data frames, and then sends the data frames to the digital display recording cloud transmission assembly via a data cable; pre-connect the well site mains power to power on the entire observation subsystem. After the system is powered on, the data receiving unit of the digital display recording cloud transmission assembly first receives the data frames from the data receiving and conversion assembly, and completes frame verification and buffering; then... The data processing unit performs engineering quantity conversion, alarm discrimination, curve interpolation, and Modbus register mapping on the verified data frames to generate standardized data that can be displayed, stored, and uploaded. Subsequently, the storage unit stores the standardized data, forming a time-stamped historical file. At the same time, the display unit, i.e., the display screen, works with the functional application display layer to display the standardized data in real time, realizing the display of digital data, curves, alarms, and human-machine interaction screens. During this process, the data transmission unit encrypts and pushes the standardized data to the cloud through the built-in 4G / 5G mobile network, enabling multiple user terminals such as computers and mobile phones to access it simultaneously. Users do not need to go to the wellhead; they only need to log in to the cloud platform through a computer browser or a WeChat mini-program on their mobile phones to view pressure curves in real time, receive over-limit alarm pushes, and download historical data files. When the network is interrupted, the data is automatically resumed locally, and the interruption is resumed after the network is restored, ensuring complete and uninterrupted records, thereby realizing three-level wireless synchronous monitoring of pressure measurement points, duty rooms, and user terminals.
