Description

Technical Field

[0001] This utility model relates to the field of industrial automation testing technology, specifically to a remote pressure monitoring terminal. Background Technology

[0002] In key sectors such as municipal water supply, petrochemicals, and energy management, long-term and continuous monitoring of pipeline pressure is a core requirement for ensuring the stable operation of the system. Traditional pressure monitoring methods mainly rely on manual on-site reading of mechanical pressure gauges, which is not only inefficient and unable to achieve real-time data acquisition and abnormal alarms, but also requires a large investment of manpower, making it difficult to meet the needs of modern monitoring.

[0003] However, existing remote pressure monitoring terminals suffer from low integration, with pressure sensing modules, communication modules, and power supply modules often being separate designs. This results in bulky equipment, cumbersome installation, significantly reduced system reliability, and high power consumption. They generally use 2G or conventional 4G communication modules, which consume a lot of energy and make it difficult to achieve long-term stable operation in battery-powered mode. Furthermore, their functions are limited, lacking local data display, convenient Bluetooth debugging, and remote upgrade capabilities, causing great inconvenience to equipment maintenance and operation. Therefore, we propose a remote pressure monitoring terminal. Utility Model Content

[0004] In view of the problems existing in the above-mentioned remote pressure monitoring terminals, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a remote pressure monitoring terminal, which solves the problems of existing remote pressure monitoring terminals, such as low integration, pressure sensing module, communication module, power supply module, etc., which are mostly designed separately, resulting in large device size, cumbersome installation, and significantly reduced system reliability. In addition, the power consumption is relatively high, generally using 2G or conventional 4G communication modules, which consume a lot of energy and are difficult to achieve long-term stable operation in battery power mode. At the same time, the functions are limited, lacking local data display, convenient Bluetooth debugging and remote upgrade capabilities, which brings great inconvenience to equipment maintenance and operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A remote pressure monitoring terminal includes a terminal housing, a power supply battery, and a pressure sensor. The terminal housing contains a measurement board, a communication board, and a display control board. A pressure sensor is fixedly mounted on the bottom of the terminal housing and electrically connected to the measurement board. The communication board includes a low-power wide-area network module, and the display control board includes a Bluetooth debugging module. The display control board is electrically connected to both the measurement board and the communication board. A sealing joint is fixedly mounted on the bottom of the terminal housing, and the detection end of the pressure sensor extends out of the terminal housing through the sealing joint. A power supply battery is fixedly mounted inside the terminal housing.

[0007] Preferably, a sealing plug is fixedly installed on the top of the terminal housing, and a gain antenna is provided inside the sealing plug. The gain antenna is electrically connected to the low-power wide area network module.

[0008] Preferably, the surface of the terminal housing is provided with a display screen, and a data storage module is fixedly installed inside the terminal housing. Both the display screen and the data storage module are electrically connected to the display control board.

[0009] Preferably, the terminal housing is a high-strength, weather-resistant engineering plastic housing, the power supply battery is a lithium thionyl chloride battery, and the power supply battery is electrically connected to the display control board.

[0010] Preferably, an alarm indicator icon is provided on one side inside the display screen, and the alarm indicator icon is electrically connected to the display control board.

[0011] Preferably, the seams of the terminal housing are provided with silicone rubber sealing rings and anaerobic sealant.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention integrates the measuring board, communication board, and display control board into the main body of the terminal, and encapsulates them together with the pressure sensor and power supply battery in a single terminal shell, replacing the traditional split design. This effectively solves the problems of large size and complicated installation. The integrated structure reduces the number of connection nodes between modules, significantly reducing signal interference and failure risk, and significantly improving the reliability of system operation. At the same time, the communication board adopts a low-power wide area network module, paired with a high-capacity lithium thionyl chloride battery to power the entire device. Compared with traditional modules, energy consumption is greatly reduced. This design can meet the long-term stable operation requirements in battery-powered mode, avoiding frequent battery replacements. It is especially suitable for monitoring scenarios in uninhabited areas and without external power sources, reducing operation and maintenance costs.

[0013] This invention features a display screen for local visualization of pressure data, a Bluetooth debugging module for convenient local parameter configuration, a data storage module for storing monitoring data, and a low-power wide-area network module for remote pressure data transmission and device management. This solves the problems of lacking local display, Bluetooth debugging, and remote upgrade capabilities, significantly simplifying maintenance processes. Furthermore, the terminal casing is made of high-strength, weather-resistant engineering plastic, with double sealing at the seams using silicone rubber sealing rings and anaerobic sealant. Combined with the top sealing plug design, it effectively prevents dust and moisture intrusion, ensuring stable operation of the equipment in outdoor, humid, or dusty environments such as municipal water supply and petrochemical industries, thus improving environmental adaptability.

The terminal housing 1 contains a measuring board 5, a communication board 6, and a display control board 7. The pressure sensor 3 is fixedly installed at the bottom of the terminal housing 1 and is electrically connected to the measuring board 5. The communication board 6 includes a low-power wide-area network module 8, and the display control board 7 includes a Bluetooth debugging module 9. The display control board 7 is electrically connected to both the measuring board 5 and the communication board 6. A sealing connector 10 is fixedly installed at the bottom of the terminal housing 1, and the detection end of the pressure sensor 3 extends out of the terminal housing 1 through the sealing connector 10. The power supply battery 2 is fixedly installed inside the terminal housing 1.

[0020] This utility model discloses a remote pressure monitoring terminal. A sealing plug 11 is fixedly installed on the top of the terminal housing 1. A gain antenna 12 is provided inside the sealing plug 11. The gain antenna 12 is electrically connected to a low-power wide area network module 8.

[0021] This utility model discloses a remote pressure monitoring terminal. The surface of the terminal housing 1 is provided with a display screen 13, and a data storage module 14 is fixedly installed inside the terminal housing 1. Both the display screen 13 and the data storage module 14 are electrically connected to the display control board 7.

[0022] This utility model discloses a remote pressure monitoring terminal.

[0024] This utility model discloses a remote pressure monitoring terminal, wherein the seam of the terminal housing 1 is provided with a silicone rubber sealing ring 16 and an anaerobic sealant 17.

[0025] In use, the pressure sensor 3 at the bottom of the terminal housing 1 extends out of the housing through the sealing connector 10, directly contacting the fluid in the pipeline network. It collects the physical pressure signal in the pipeline network in real time and converts it into a transmittable electrical signal, which is then transmitted to the measuring board 5.

Then, it transmits the processed digital pressure data to the display control board 7. Upon receiving the data, the display control board 7 simultaneously completes three operations: transmitting the data to the display screen 13 on the surface of the terminal housing 1 for local visualization of pressure data and equipment status; storing the data in the internal data storage module 14 to retain historical monitoring records and prevent data loss; and determining whether the pressure data exceeds a preset threshold. Normally, the alarm indicator icon 15 on the top is triggered, and then the remote data transmission and local debugging display control board 7 transmits the processed pressure data to the communication board 6. The low-power wide area network module 8 of the communication board 6 transmits the data remotely to the monitoring platform through the gain antenna 12 inside the top sealed plug 11, realizing real-time remote monitoring and management of pressure data. When local debugging of the equipment is required, the staff can pair the mobile terminal with the Bluetooth debugging module 9 of the display control board 7 to easily configure the equipment parameters.
