It should be understood that this application is not limited to the exemplary embodiments described herein.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more," meaning that in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be construed as a limitation on the quantity. "Multiple" means two or more.

[0026] While ordinal numbers such as "first," "second," etc., will be used to describe various components, there is no limitation on which components are used herein. The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form also includes the plural form, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0028] An illustrative example of a laser control method based on wireless communication: Figures 1 to 5 As shown, a laser control method based on wireless communication according to an embodiment of this application is illustrated. This method provides a novel wireless communication mode, enabling platforms such as mobile phones or tablets to control the laser, solving the problem that traditional laser debugging schemes generally require carrying a computer. This allows lasers to have more options for integration into smart factory systems, facilitating laser debugging and possessing practical application value. The wireless communication-based laser control method is suitable for communication between mobile phones and devices equipped with lasers. That is, operators can communicate with devices equipped with lasers, and thus with the lasers themselves, via their mobile phones.

[0029] Specifically, such as Figure 1 As shown, the laser control method based on wireless communication includes: S110, configuring a network for a first controller, the first controller including at least one serial peripheral interface; S120, uploading the network configuration data of the first controller through a laser client; S130, determining whether the first controller is wirelessly connected to the laser; S140, in response to the first controller being wirelessly connected to the laser, activating the wireless access point; and S150, in response to the mobile phone successfully pairing with the Bluetooth corresponding to the laser, transmitting the laser data to the mobile phone through the first controller.

[0030] In step S110, the first controller is configured with a network. Specifically, the first controller is used to configure the network for the laser and further serves as a bridge for wireless communication between the laser and the mobile phone, enabling wireless communication between the laser and the mobile phone.

[0031] In this embodiment, the first controller is an ESP32 chip, which has multiple SPI interfaces. Bluetooth is used for network configuration of the first controller. It should be understood that the first controller can also be other types of chips with Wi-Fi and Bluetooth functionality, such as an STM32 chip.

[0032] Subsequently, the wireless network corresponding to the first controller can be modified via Bluetooth, that is, the name and password of the Wi-Fi can be changed, and the first controller can also be restarted.

[0033] Accordingly, in some embodiments of this application, the laser control method based on wireless communication further includes: modifying the Wi-Fi name and / or Wi-Fi password corresponding to the first controller via a mobile phone. The laser control method based on wireless communication also includes: restarting the first controller via a mobile phone.

[0034] It's worth noting that in some scenarios, multiple lasers may exist in an area, each equipped with a primary controller. The mobile phone then needs to identify the laser it intends to connect to. Therefore, each primary controller corresponding to a laser needs to be configured with its own network. Furthermore, the networks corresponding to multiple lasers can be distinguished by their Wi-Fi names.

[0035] In step S140, in response to the first controller wirelessly connecting to the laser, the wireless access point is activated. It is also worth mentioning that the ESP32 chip may fail to connect to the mobile phone's wireless access point (AP) in complex environments. Therefore, the ESP32 chip can actively activate the wireless access point to allow the mobile phone to connect to the ESP32 chip.

[0036] Accordingly, in some embodiments of this application, step S140 includes: in response to the first controller wirelessly connecting with the laser, the first controller controls the activation of the wireless access point.

[0037] In step S150, in response to successful Bluetooth pairing between the mobile phone and the laser, the data of the laser is transmitted to the mobile phone via the first controller. Specifically, the laser is connected to a second controller, and the second controller is connected to the first controller. In some embodiments of this application, the second controller is a W5500 chip.

[0038] The W5500 chip connects to the SPI interface of the ESP32 chip, enabling communication between them. The W5500 chip connects to the laser via an RJ45 port to read laser data. The ESP32 chip decodes the data and sends it to the mobile phone. This allows the phone to display real-time laser data.

[0039] Accordingly, step S150 includes: reading the laser data through the second controller; transmitting the laser data read by the second controller to the first controller through the second controller; decoding the laser data transmitted by the second controller through the first controller; and transmitting the decoded laser data to the mobile phone through the first controller.

[0040] In some embodiments of this application, the laser control method based on wireless communication further includes: adjusting the laser via the mobile phone based on data transmitted to the mobile phone.

[0041] If the laser needs to be remotely managed, it can also be connected to the public network via a router, so that it can be remotely debugged and upgraded via OTA by mobile phones or other devices.

[0042] It is worth mentioning that, since this application uses wireless data transmission and reception, the laser can be debugged simply by bringing a mobile phone or other debugging equipment close to it. No wiring is required for data transmission.

[0043] In summary, a laser control method based on wireless communication based on the embodiments of this application has been clarified. The laser control method based on wireless communication provides a solution for wireless communication with the laser, which solves the problem that traditional laser debugging solutions basically require carrying a computer, thus providing convenience for laser debugging and having practical application value.

[0044] The present application and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present application. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the spirit of the present application, such design should fall within the protection scope of the present application.
