Description

Technical Field

[0001] The utility model relates to the technical field of data acquisition, and in particular to a multifunctional data acquisition terminal based on the Internet of Things. Background Art

[0002] An IoT data collection terminal is a device that connects the sensor network layer and the transmission network layer in the IoT, collecting data and sending it to the network layer. It is responsible for multiple functions such as data collection, preliminary processing, encryption, and transmission.

[0003] A Chinese patent with announcement number CN220965349U discloses an Internet of Things data acquisition terminal, including a terminal body, a waterproof wiring structure provided on the back of the terminal body, a number of fixed nodes symmetrically provided on both sides of the terminal body, a heat dissipation structure provided inside the terminal body and extending to the outside, the terminal body including a waterproof shell, a wiring terminal provided on the back of the waterproof shell, a sealing strip provided on the periphery of the wiring terminal near the back, a sealing threaded hole provided on the periphery of the sealing strip and in front of the sealing strip, a number of antenna terminals symmetrically provided on the front of the terminal body, a sealing cover provided on the periphery of the antenna terminal, a waterproof wiring structure including a waterproof cover, and a sealing fixing hole provided on the periphery of the waterproof cover corresponding to the sealing threaded hole.

[0004] The above-mentioned Internet of Things data acquisition terminal improves the waterproof performance of the Internet of Things data acquisition terminal by providing a waterproof wiring structure.

[0005] However, the above-mentioned Internet of Things data acquisition terminal still has some defects in actual use. When some sensors have been connected to the wiring terminals of the Internet of Things data acquisition terminal, when some collection sensors need to be added, the first step is to loosen the waterproof glands on the already connected sensors to prevent the connected sensors from being disconnected from the wiring terminals due to pulling during the removal of the waterproof cover. The second step is to remove the waterproof cover to expose the wiring terminals before connecting new sensors. The whole operation process is relatively cumbersome, and when the wiring terminals on the Internet of Things data acquisition terminal are not fully connected, external dust and water vapor may still enter the wiring terminals from the middle channel of the waterproof glands, and the dustproof and waterproof effects need to be improved.

[0006] To this end, we propose a multifunctional data acquisition terminal based on the Internet of Things. Utility Model Content

[0034] Please refer to Figures 1 to 6 As shown, this embodiment provides a multifunctional data acquisition terminal based on the Internet of Things, including a data acquisition terminal body and a protective shell 101. The data acquisition terminal body includes a shell 1, and a data acquisition circuit board 106 is fixedly installed inside the shell 1. A wiring port 103 electrically connected to the signal receiving port of the data acquisition circuit board 106 is provided on one side of the shell 1. There are multiple wiring ports 103. The protective shell 101 is fixedly connected to a side of the shell 1 close to the wiring port 103. The wiring port 103 is located on the inner side of the protective shell 101. The top of the protective shell 101 is open. The open end of the protective shell 101 is detachably installed with a cover plate 2. A waterproof gland 102 corresponding to the wiring port 103 is provided on one side of the wiring port 103.

[0035] By adopting the above technical solution, when it is necessary to add a sensor connected to the wiring port 103, it is only necessary to remove the cover 2, then pass the new sensor terminal through the corresponding waterproof gland 102 and connect it to the wiring port 103, and then install the cover 2 on the protective shell 101. The whole process is more convenient and quick to operate, and will not affect the connection of other sensors.

[0036] In this embodiment, in order to ensure the sealing of the connection between the cover plate 2 and the protective shell 101, a sealing groove 1013 is opened on the top of the protective shell 101, and a sealing ring 1014 is arranged in the sealing groove 1013. The sealing ring 1014 is arranged between the bottom of the cover plate 2 and the top of the protective shell 101.
