[0017] This utility model has the following beneficial effects:
[0018] 1. This utility model, through the setting of modular interfaces and processor motherboards, features a modular multi-sensor data acquisition integration box with a compact structure, diverse functions, and strong compatibility. Through standardized interfaces and multi-protocol adaptation mechanisms, it enables rapid access and efficient data acquisition from various sensors, improving the flexibility, scalability, and environmental adaptability of the equipment. It meets the needs of multiple scenarios such as meteorological monitoring, urban sensing, and agricultural IoT, and solves the problem that existing multi-sensor data acquisition devices usually adopt a fixed design, with each sensor interface and communication protocol bound together, making it difficult to flexibly replace or expand. While some portable acquisition terminals are small in size, they have obvious shortcomings in multi-protocol adaptation, edge computing capabilities, and remote communication, which limits their applicability in complex environments.
[0019] 2. This utility model, by setting up a protective limiting component, allows the sealing gasket to seal the modular interface, providing dust and water protection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1
[0029] Please see Figures 1 to 4 This utility model is a modular multi-sensor data acquisition integration box, including a lower shell 100 and an upper shell 101 mounted on top of it by screws. A modular interface 200 is arrayed on one side wall of the upper shell 101 from front to back. A processor motherboard 300 is mounted inside the lower shell 100 by screws.
[0030] Specifically, a charging port 101a is provided at the center of the other side wall of the upper shell 101, and a display panel 101b is provided at the center of the top of the upper shell 101; a mounting bracket 102 is installed inside the top of the upper shell 101 by screws, and a lithium battery 102a is installed inside the mounting bracket 102; a multi-protocol communication module 301 is provided on one end of the surface of the processor motherboard 300, and the multi-protocol communication module 301 is electrically connected to the adjacent modular interface 200.
[0031] Furthermore, the outer casing assembly consists of a lower shell 100 and an upper shell 101, made of lightweight engineering plastic or aluminum alloy, with dimensions of 155mm × 90mm × 43mm, and an IP65 protection rating. The main control unit is the processor motherboard 300, equipped with a high-performance embedded processor (such as ARM). The Cortex-M3 processor is responsible for data acquisition, processing, and scheduling. The modular interface 200 has multiple built-in standard slots or connectors, supporting users to connect various sensor modules such as temperature and humidity, air pressure, wind speed, and PM2.5 as needed. The multi-protocol communication module 301 integrates physical interfaces such as RS485, I2C, SPI, and CAN, and supports communication protocols such as Modbus, MQTT, HTTP, and CoAP. It can automatically identify or manually configure protocol parameters according to the sensor type. The processor motherboard 300 has a wireless communication unit that includes multiple communication methods such as 4G / 5G, Wi-Fi, and NB-IoT, supporting data upload to the cloud or local server. The power management system supports external power supply, solar panel power supply, and 102a lithium battery power supply modes, and has a low-power sleep mechanism. The software platform has a built-in edge computing engine, supporting functions such as data filtering, anomaly detection, and alarm threshold setting. It can be configured and debugged via Bluetooth / Wi-Fi connection to a mobile app or PC.
[0032] The operation process of this embodiment is as follows: The integrated box is only 1 / 10 of that of a conventional weather station device, weighs less than 400g, is easy to carry and deploy quickly, supports more than 20 common sensor protocols, has a wide range of compatibility, a data acquisition frequency of up to 1kHz, fast response speed, and a battery life of more than 7 days in typical application scenarios. It can operate stably in environments from 0℃ to +60℃, adapts to complex outdoor conditions, supports OTA remote upgrades and parameter configuration, is easy to maintain, and its modular design allows users to flexibly replace or add sensor modules as needed, improving the equipment reuse rate. Example 2
[0033] Please see Figure 2 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is that a protective limiting component 400 is provided. The protective limiting component 400 includes a pressure plate 401 disposed on the outside of the modular interface 200, and a clamping plate 403 fixed at the bottom center of the pressure plate 401. This solves the problem that the external interface of the existing multi-sensor data acquisition equipment lacks dustproof and waterproof measures, which can easily affect the normal use of the interface. At the same time, the external sensor connector lacks limiting measures, which affects the stability of the connector.
[0034] Specifically, a sealing gasket 402 is arrayed and bonded to one side wall of the pressure plate 401 from front to back, and a slot 403a is provided on the bottom of the clamping plate 403 from front to back; sliders 404 are fixedly provided at the bottom of both the front and rear ends of the pressure plate 401, and the sliding holes in the sliders 404 are slidably installed on the outer wall of the guide rod 405. A first spring 405a is sleeved on the outer wall of the guide rod 405; the two ends of the guide rod 405 are fixed on the inner wall of the connecting frame 406, and the first spring 405a is located between the upper surface of the slider 404 and the inner wall of the connecting frame 406; a telescopic rod 407 is installed in the middle of one side wall of the connecting frame 406, and the other end of the telescopic rod 407 is installed on the outer wall of the upper shell 101. A second spring 407a is sleeved on the outer wall of the telescopic rod 407.
[0035] Furthermore, the sealing gasket 402 will be placed on the outer wall of the modular interface 200 to seal against dust and water. The slider 404 can slide up and down along the outer wall of the guide rod 405. When it moves up, it will compress the first spring 405a. The telescopic rod 407 will limit the second spring 407a. The second spring 407a mainly plays a stretching role when the connecting frame 406 moves.
[0036] The operation process of this embodiment is as follows: When the integrated box is not in use, the pressure plate 401 is pressed against the outside of the modular interface 200. The sealing gasket 402 is located on the outside of the modular interface 200 to prevent dust and water. When it is necessary to connect an external sensor, the pressure plate 401 is pulled outward first. The pressure plate 401 is subjected to force and moves the connecting frame 406 outward through the slider 404, and stretches the telescopic rod 407 and the second spring 407a. Then, the pressure plate 401 is pulled upward. The pressure plate 401 is subjected to force and moves upward under the action of the slider 404 and the guide rod 405, and squeezes the first spring 405a. At this time, the pressure plate 401 can be moved out of the outside of the modular interface 200. Then, the sensor connector can be inserted into the modular interface 200. Then, the force applied to the pressure plate 401 is stopped, so that the slot 403a on the card plate 403 is locked on the outer wall of the sensor connector, which plays a limiting role and ensures the stability of the sensor connector.
