[0002] A data logger is an electronic device used to collect, display, and record various industrial parameters such as temperature, pressure, current, and displacement. It is widely used in industrial settings including power, metallurgy, chemical, food processing, and environmental monitoring. Currently, most mainstream data loggers adopt a paperless design, displaying real-time data on an LCD screen and saving the collected data using USB flash drives or Flash storage media. These devices typically support multi-channel signal input, full signal type compatibility, curve history playback, report generation, and remote communication, meeting the diverse data acquisition and analysis needs of industrial sites.
[0003] However, existing data loggers still have certain limitations: the products adopt an integrated structure, which has a high degree of integration, but the modules cannot be disassembled, making maintenance difficult and subsequent upgrades inconvenient. More importantly, the heat generated by the main control chip during operation can interfere with the accuracy of data collected by the functional chips. Utility Model Content

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.
[0029] A data logger includes a human-computer interaction module and a functional module.
[0030] Regarding the human-computer interaction module, such as Figures 1 to 3 As shown, the human-computer interaction module includes an interaction housing 11, a touch screen 12, and a human-computer interaction circuit board 13: as Figures 1 to 3 As shown, the interactive housing 11 is composed of a front housing 111 and a rear housing 112 assembled together. The front housing 111 and the rear housing 112 can be assembled by snapping them together and then connecting them with screws, which is convenient and stable; as shown Figure 1 and Figure 3 As shown, the touchscreen 12 is installed on the front side of the front housing 111. The touchscreen 12 can be installed by snapping it into a slot on the front side of the front housing 111 and then adhesively fixing it in place. Figure 1 As shown, the human-computer interaction circuit board 13 is installed inside the interaction housing 11 and is electrically connected to the touch screen 12; as Figure 1 and Figure 2 As shown, the rear side of the outer shell 112 is provided with a power interface 117 and a communication interface 118 for the human-machine interface circuit board 13, as well as at least two insertion slots 113 for installing functional modules. The communication interface 118 of the human-machine interface circuit board 13 can be an RS485 interface. Figure 2As shown, a USB port 119 can also be provided on the rear side of the outer shell 112 to facilitate data import and export; as Figure 1 As shown, a snap-fit 114 for embedded installation can also be provided on the outer side of the front shell 111, and a rubber ring 115 for shock absorption during embedded installation can be provided on the interactive shell 11. This allows for quick embedding into a wall or bracket using the snap-fit 114 and shock absorption using the rubber ring 115. Figure 2 As shown, a heat dissipation groove 116 can also be provided in the corresponding area of the human-machine interaction circuit board 13 on the rear side of the outer shell 112. In this way, the heat dissipation groove 116 can be used to effectively dissipate the heat generated during operation, avoid local overheating, and keep the human-machine interaction circuit board 13 working within a stable temperature range.
[0031] Regarding functional modules, such as Figures 1 to 4 As shown, the functional module includes a functional housing 21 and a functional circuit board 22: Figure 1 and Figure 4 As shown, the functional housing 21 is composed of an upper shell 211 and a lower shell 212 assembled together. The upper shell 211 and the lower shell 212 can be assembled by snapping them together and then connecting them with screws, which is convenient and stable. Figure 1 As shown, the functional circuit board 22 is installed inside the functional housing 21; as Figures 1 to 4 As shown, the front end of the functional housing 21 is provided with a power interface 215 and a communication interface 216 for the functional circuit board 22. When the functional housing 21 is inserted into the insertion slot 113 in a guided manner, the power interface 215 and the communication interface 216 of the functional circuit board 22 are respectively inserted into the human-machine interface circuit board 13. The communication interface 216 of the functional circuit board 22 can be an I2C interface. The two sides of the functional housing 21 can slide and engage with the dovetail groove structures on both sides of the insertion slot 113 via dovetail-shaped slide rail structures 214, ensuring reliable guidance. Figures 1 to 4 As shown, stops 213 can also be provided on both sides of the rear end of the functional housing 21. After the functional housing 21 is inserted into the insertion slot 113, the stops 213 abut against the rear housing 112 to achieve positioning when in place. After the functional housing 21 is inserted into place, the stops 213 are screwed to the rear housing 112. This can not only play a positioning role, but also stabilize the connection.
[0032] In this application, the external structure and dimensions of each functional module and insertion slot 113 are identical and interchangeable. The specific number of functional modules and insertion slots 113, as well as the specific type of functional modules, can be set according to actual requirements. For example, in this embodiment: Figures 1 to 3 As shown, two insertion slots 113 and two functional modules are used; both functional modules are either data acquisition modules, either both are switch output modules, or either are a data acquisition module and a switch output module respectively.
[0033] In this embodiment, the power interface 215 and communication interface 216 of the functional circuit board 22 are connected to the human-machine interaction circuit board 13 through pin headers and female headers, and the connection is stable and reliable.
[0034] The instrument adopts a split structure, with each functional module and the functional modules and the human-machine interface module being independent yet detachably connected. Since power consumption and heat are mainly concentrated on the human-machine interface circuit board 13, the human-machine interface circuit board 13 can be spatially isolated from other functional circuit boards 22, thereby avoiding the heat generated by the human-machine interface circuit board 13 during operation from interfering with the accuracy of the data collected by the functional circuit board 22. The functional modules and insertion slots 113 in the instrument are interchangeable, and different functional modules can be replaced according to actual needs. Furthermore, it has at least two insertion slots 113, which can be expanded according to actual needs, providing good configurability and expandability. When the functional module is guided and inserted into the insertion slot 113 and is in place, the power interface 215 and communication interface 216 of the functional circuit board 22 are inserted into the human-machine interface circuit board 13. No additional wiring is required when assembling or replacing modules, making operation simple and easy to assemble and maintain.
