[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0036] It should be noted that although functional modules are divided in the system diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0037] refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the system connection structure of an air curtain machine with multiple communication methods. Figure 2 This is a schematic diagram of the circuit structure of the first wired module. Figure 3This is a schematic diagram of the circuit structure of the second wired module.

[0038] The purpose of this invention is to provide an air curtain machine that offers multiple communication options, facilitating future networking of air curtain machines.

[0039] Therefore, this application provides an air curtain machine with multiple communication methods, including: a control module, a first wired module, a second wired module, a wireless module, and a configuration module.

[0040] The control module provides an interface for communication with the first wired module, the second wired module, and the wireless module. The configuration module provides physical buttons, allowing the user to select the appropriate communication method and inform the control module of that method.

[0041] The control module is connected to the first wired module, the second wired module, the wireless module, and the configuration module, respectively. In some further preferred embodiments, the control module is a microcontroller-based control module. Because microcontrollers have good versatility and intelligence, a control module based on a microcontroller can realize the control functions of the air curtain machine.

[0042] To facilitate easier configuration by users, the configuration module comprises two DIP switches: a first DIP switch and a second DIP switch. One end of the first DIP switch is connected to the first general-purpose I / O port of the control module, and one end of the second DIP switch is connected to the second general-purpose I / O port of the control module.

[0043] In order for the DIP switches to generate signals through DIP switching, two DIP switches are connected to a high-level node. Specifically, the other end of the first DIP switch is connected to the high-level node, and the other end of the second DIP switch is connected to the high-level node. The high-level node can provide a high-level signal.

[0044] In this way, by selecting whether to connect to a high-level node via the first DIP switch, a low-level signal or a high-level signal is generated in the first general-purpose I / O port of the control module. When the first DIP switch is selected to connect to a high-level node, a high-level signal is generated in the first general-purpose I / O port of the control module. When the first DIP switch is selected not to connect to a high-level node, a low-level signal is generated in the first general-purpose I / O port of the control module.

[0045] Similarly, the second DIP switch selects whether to connect to a high-level node, thereby generating a low-level or high-level signal in the second general-purpose I / O port of the control module. When the second DIP switch is selected to connect to a high-level node, a high-level signal is generated in the second general-purpose I / O port of the control module. When the second DIP switch is selected not to connect to a high-level node, a low-level signal is generated in the second general-purpose I / O port of the control module.

[0046] In the control module, the combination of high and low levels of its first and second general-purpose I / O ports forms the configuration signal.

[0047] The control module selects a wireless module, a first wired module, or a second wired module as the communication module for communication based on the configuration signal.

[0048] For example, when environmental constraints necessitate wireless communication, the first DIP switch can be connected to a high-level node, while the second DIP switch is not connected to a high-level node. This sets the configuration signal to 10. Upon receiving this configuration signal, the control module can then use the wireless module as a communication module for future network deployments.

[0049] When environmental constraints necessitate wired communication, the first DIP switch and the second DIP switch can be connected to a high-level node, thus setting the configuration signal to 11. Upon receiving this configuration signal, the control module can then use the first wired module as the communication module for future network deployment.

[0050] When environmental constraints necessitate wired communication, the first DIP switch can be disconnected from the high-level node, while the second DIP switch is connected to the high-level node. This sets the configuration signal to 01. Upon receiving this configuration signal, the control module can then use the second wired module as the communication module for future network deployments.

[0051] This invention improves the ease of installation and networking of the air curtain machine by incorporating different communication methods within the air curtain unit and utilizing a configuration module with DIP switches for easy selection of the appropriate communication method by installers.
