[0002] In the field of geotechnical safety monitoring, traditional data acquisition terminals generally suffer from insufficient protection, high dependence on power supply, and poor data transmission stability. Existing equipment mostly adopts a split structure with low waterproof and dustproof ratings, making it difficult to meet the long-term operational needs of complex outdoor environments such as dams, reservoirs, and bridges. They are prone to circuit failures due to rainwater infiltration, dust accumulation, or electromagnetic interference. Their power supply mainly relies on external power grids or disposable batteries, which cannot meet the monitoring needs of areas without power supply, and frequent battery replacements increase maintenance costs. Traditional terminals mostly employ a single wireless communication mode, which is prone to data transmission interruptions in areas with weak signals. Furthermore, their networking capabilities for multiple devices are limited, making it difficult to achieve efficient collaboration in large-scale distributed monitoring systems. To address these issues, there is an urgent need for a highly integrated wireless data acquisition terminal with excellent protection performance, self-sufficient power supply, and multi-mode communication capabilities to improve the reliability of monitoring data and the flexibility of system deployment.

The base 12 is sealed to the housing 2 by the sealing ring 7 installed on the side wall and fixed by screws, and the exhaust valve 11 is installed on the end face of the base 12.

[0024] It also includes a battery mounting backplate 5, which is disposed inside the housing 2 and is used to fix the battery 3.

[0025] In this embodiment, the housing 2 and the base 12 are encapsulated in a fully sealed, integrated manner. A sealing ring 7 is provided on the side wall of the base 12 and secured with screws. The sealing ring 7 is made of silicone rubber, which has high elasticity and weather resistance, effectively blocking rainwater, dust, and electromagnetic interference, ensuring stable operation of the internal circuitry in humid or dusty environments. An exhaust valve 11 is provided on the end face of the base 12 to expel air from inside the housing 2 during the encapsulation process, preventing internal pressure fluctuations caused by temperature changes and further improving sealing. This design enables the equipment to achieve an IP67 protection rating, meeting the long-term usage requirements of complex outdoor environments such as dams and reservoirs.

[0026] A solar panel 1 is tilted at the top of the housing 2, and its angle can be optimized according to the sunlight conditions of the installation area to maximize energy absorption efficiency. The solar panel 1 is electrically connected to the internal battery 3 via wires. The battery 3 is a lithium polymer battery with high energy density and long cycle life. The battery fixing backplate 5 securely fixes the battery 3 to the housing 2 with a snap-fit ​​structure to prevent the battery 3 from shifting during transportation or vibration and causing a short circuit. This design allows the equipment to operate continuously in environments without external power supply, reduces maintenance costs, and is suitable for monitoring scenarios in remote areas or without grid coverage.

[0027] Housing 2 is made of high-strength ABS engineering plastic with a UV-resistant coating, and has a temperature resistance range of -40℃ to +70℃. The fully sealed structure has passed IP67 protection testing, resisting immersion in water, sand, and acid / alkali corrosion. An internal temperature compensation module ensures the accuracy of sensor data under extreme temperatures. This design makes the equipment suitable for harsh environments such as high altitudes and coastal salt spray, guaranteeing long-term monitoring reliability.

[0028] Optionally, the base 12 has a plurality of aviation connectors 8 at its bottom for connecting external sensors and configuration devices. There are seven aviation connectors 8 in total, six of which are used to connect to a six-channel piezometer, and the other is used for charging and 485 configuration.

[0029] It should be noted that the base 12 has seven aviation connectors 8 at its bottom, six of which are used to connect the six-channel piezometer, and the other is used for charging and 485 configuration. The aviation connectors 8 use waterproof IP68 interfaces, and the plug-in structure is designed with a self-locking mechanism to ensure a secure connection and prevent accidental contact. The layout of the aviation connectors 8 distributes stress concentration, avoiding poor contact due to long-term use. This design supports quick sensor replacement and allows for remote parameter adjustment through an independent configuration interface, improving the flexibility and compatibility of the equipment.

[0030] Optionally, a magnetic switch is provided on the side of the housing 2, which is operated by an external magnet to restart the device.

[0031] It should be noted that a magnetic switch is located on the side of the casing. An external magnet is brought near the switch to activate it, enabling a soft restart of the device. The magnetic switch uses a reed switch structure, eliminating mechanical wear and providing high responsiveness, making it suitable for frequent operation scenarios. After restarting, the device automatically enables Wi-Fi, allowing users to remotely configure parameters via an app. This design simplifies the on-site debugging process, avoids the need to disassemble the casing in case of equipment malfunctions, and reduces maintenance difficulty.

[0032] Optionally, the communication control board 6 integrates 4G and LoRa wireless communication modules for wireless data transmission and wireless networking of multi-point devices.

[0033] It should be noted that the communication control board 6 integrates 4G and LoRa dual-mode wireless communication modules. The 4G module supports wide area network data backhaul, while the LoRa module enables short-range multi-point networking. The device can network with up to nine slave wireless devices via the LoRa protocol, forming a star network topology. A single host can collect 60 channels of seepage pressure data. This design meets the requirements for simultaneous push from multiple data centers and is suitable for distributed deployment in large-scale monitoring systems such as dams and bridges.

[0034] Optionally, it also includes an antenna base 10, which is disposed on the base 12 and is used to mount the antenna.

[0035] It should be noted that an antenna base 10 is mounted on the base 12 for installing a detachable antenna. The antenna base 10 employs a metal shielding structure to reduce external electromagnetic interference and supports antenna height adjustment, optimizing signal coverage. In areas with weak signals, an external high-gain antenna can be used to extend the transmission distance. This solves the signal attenuation problem in underground or metallic environments, ensuring reliable data transmission.

[0036] Optionally, the base 12 is provided with several fixing slots 9 for fixing the integrated wireless acquisition terminal.

[0037] It should be noted that multiple fixing slots 9 are formed on the surface of the base 12. The slots have a T-shaped cross-section, accommodating mounting brackets of different sizes. The distribution of the fixing slots 9 has been mechanically calculated to ensure stable fixation of the equipment in vibrating environments such as high slopes or bridges. This design supports various installation methods, including wall mounting and column mounting, adapting to complex terrain requirements and reducing on-site construction difficulty.

[0038] Optionally, the vibrating wire acquisition board 4 is configured to acquire data from multiple sensors and wirelessly transmit it to multiple data centers via the communication control board 6; The integrated wireless acquisition terminal is networked with up to 9 slave wireless devices through the communication control board 6, enabling the acquisition of up to 60 channels of seepage pressure data.

[0039] It should be noted that the vibrating string acquisition board 4 adopts multi-channel synchronous sampling technology, with a sampling frequency of ≥1kHz per channel, supporting parallel data acquisition from six piezometers. The acquired data is transmitted to the communication control board 6 via the SPI bus, encrypted by the 4G / LoRa module, and then uploaded to the cloud or local server. The device has a built-in low-power sleep mechanism that automatically enters power-saving mode during non-acquisition periods, extending the battery life of 3.

[0040] Instructions: First, install the device to the monitoring target location using the T-shaped fixing slot 9 at the bottom of the base 12, and secure it with mounting brackets or screws, ensuring the device is stable and the solar panel 1 faces the direction of sufficient sunlight. Then, connect the six piezometer sensors and the charging / 485 configuration interface via the seven aviation plugs 8 at the bottom. Six of the waterproof IP68 interfaces connect to the CH1-CH6 piezometers respectively, and the seventh interface is used for external power charging or configuring device parameters via the 485 protocol. After completing the hardware connection, the device defaults to low-power operation mode. Users can trigger a device restart by shaking the external magnet near the magnetic switch on the side of the housing 2. After restarting, the WIFI function is automatically activated, and a mobile phone or computer APP can connect to the device in real time for parameter adjustment and data visualization monitoring. During the data acquisition phase... The device simultaneously acquires six channels of seepage pressure data via the vibrating wire acquisition board 4. The data is then uploaded to the cloud server via the 4G module built into the communication control board 6. Simultaneously, it connects with up to nine slave devices via a LoRa module, forming a star network topology to achieve distributed acquisition of 60 channels of seepage pressure data and simultaneous push from multiple data centers. During operation, the solar panel 1 continuously charges the lithium polymer battery 3, and the battery mounting backplate 5 ensures stable power supply to the battery 3. If the ambient temperature is abnormal, the device's built-in temperature compensation module automatically calibrates the sensor data to ensure monitoring accuracy. The fully sealed IP67 protection structure can withstand immersion in water, dust, and electromagnetic interference, making it suitable for extreme environments ranging from -40℃ to +70℃. Users do not need frequent on-site intervention; they only need to periodically diagnose the device status remotely via the APP to optimize parameters or handle fault warnings.
