Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) switch technology, specifically to a multi-channel switch based on the Internet of Things. Background Technology

[0002] Laboratory power supply is typically designed and arranged by relevant designers or engineers based on the experimental tasks undertaken by the laboratory. This involves multiple electrical appliances and their corresponding power on / off requirements. Existing switches are usually single-contact switches that can only manually switch one circuit at a time, and cannot simultaneously and automatically control the on / off of multiple circuits, resulting in low operational efficiency. When there are many electrical appliances to be connected, multiple switches are required, which are more complex in structure, resulting in a larger structure size, occupying more space, increasing the difficulty of installation and use, and causing messy wiring in the laboratory that is difficult to organize, and may even adversely affect experimental operations. Furthermore, when the circuit structure is too complex, the switches are prone to mutual interference, affecting normal use. Summary of the Invention

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please refer to Figures 1-5. The present invention provides a technical solution: a multi-way switch based on the Internet of Things, including a switch unit 2, a mounting strip 1 and a mounting buckle 3. Multiple switch units 2 are detachably snapped onto the mounting strip 1 by the mounting buckle 3 fixed at their bottom to form a multi-way switch group. The number of switch units 2 can be increased or decreased according to actual needs, making it more flexible in use. The mounting strip 1 consists of a fixing plate 11 and two raised clamping wing plates 12 on both sides. The fixing plate 11 has fixing holes 13 arranged at equal intervals, which makes it easy to fix it to the wall, table or distribution box wall with screws. The raised clamping wing plates 12 make it easy to snap onto the mounting buckle 3 on the switch unit 2. The mounting clip 3 includes a base plate 31, which is fixed to the bottom of the switch unit 2. The base plate 31 has a fixed limiting strip 32 and an elastic limiting strip 33 on each side. To engage, first push the clamping wing plate 12 into the limiting groove of the fixed limiting strip 32, then press firmly. The other clamping wing plate 12 then engages along the wedge-shaped surface of the elastic limiting strip 33, causing the elastic limiting strip 33 to deform. Finally, the clamping wing plate 12 is engaged into the limiting groove of the elastic limiting strip 33, and the elastic limiting strip 33 returns to its original shape, completing the installation. To disassemble, pry the elastic limiting strip 33 outwards to deform it. Once the clamping wing plate 12 disengages from the limiting groove of the elastic limiting strip 33, it can be removed. The switching unit 2 includes a bottom shell 21 and a top cover 22. The top cover 22 is connected to the bottom shell 21 by screws through mounting holes 213 inside the bottom shell 21. A wire tube 26 is fixed in the middle of the bottom shell 21. An excitation coil 28 is wound around the outside of the guide tube 24.

A connecting plate 211 is provided at the position, and a support block 212 is provided inside the bottom shell 21 to support the elastic connecting plate 211 in order to increase its stability. The end of the connecting plate 211 is a terminal 24, which is located at the edge of the bottom shell 21. The excitation connection terminal 25 is electrically connected to an external IoT controller. By energizing the excitation coil 28, a magnetic field is generated inside the guide cylinder 26. This magnetic field attracts or repels the magnetic strip 27 inside, thereby driving the conductive plate 29. By moving the conductive plate 29, the connecting gate 211 is made to contact or disconnect from the connecting block 210, which plays a role in controlling the current flow. This structure does not require external power input when it is in the connected or disconnected state, and has good stability. The connecting plate 211 is made of an elastic conductive material, with one end bent into a U-shaped groove, the bottom width of which is greater than the opening width. The connecting block 210 has a teardrop-shaped cross-section, with the end width greater than the root width. When connected, the connecting block 210 is inserted into the U-shaped groove of the connecting plate 211. The slight deformation of the U-shaped groove holds the connecting block 210... Lock to ensure connection stability; The conductive plate 29 is provided with a manual pull ring 23. The manual pull ring 23 is made of insulating material and its other end passes through the bottom shell 21 and is located outside it. It is used to indicate whether the switch unit 2 is in the connected or disconnected state. It can also be manually pulled to make the switch unit 2 in the connected or disconnected state.

[0017] The IoT controller includes an AC-to-DC power supply circuit, a touchscreen, a relay control circuit, and CAT1. Wireless control and communication module. It features an efficient human-machine interface, relay on / off control, and wireless communication capabilities, with functions such as remote switching and timed switching.

[0018] The AC to DC power supply circuit on the control circuit board is used to convert AC220V into DC5V and DC3.3V. The touchscreen is used to control switches, set remote switches, and set timer switches. The relay control circuit uses the IO pins of the CAT1 wireless control communication module to control the relay switch. The relay controls the excitation coil 28 to be energized or de-energized, which can realize the control of a large current switch by a small control current signal. The relay control circuit consists of several groups, which is consistent with the number of multiplexers. The CAT1 wireless control communication module is responsible for reading the switching status of the control relay and transmitting the current parameters to the dedicated cloud through IoT standard protocols (LW2M, MQTT); Based on the above hardware environment, functions such as remote switching, timed switching, standby detection, and self-operating status analysis can be realized.
