[0035] This embodiment provides a communication interface component of a scanning device. Figure 1 is a structural block diagram of a communication interface component according to an embodiment of the present application, such as Figure 1 As shown, the communication interface assembly 10 includes a preset cable 12 and an interface slot 14 .

[0036] The interface slot 14 is provided with a first interface 141, and a communication switch circuit 142 is provided on the surface of the interface slot 14; the communication switch circuit 142 is used to switch the communication state of the communication interface assembly 10. The communication state of the communication interface assembly 10 may include a host mode state and a slave mode state.

[0037] The second interface 121 of the preset cable 12 is provided with a protrusion 122; it should be supplemented that the installation position of the protrusion 122 on the preset cable 12 needs to meet the following requirements: when the preset cable 12 is connected to the interface slot 14, the position of the protrusion 122 matches the position of the communication switch circuit 142 installed on the surface of the interface slot 14. Then, when the second interface 121 is connected to the interface slot 14 and connected to the first interface 141, the protrusion 122 is used to press the communication switch circuit 142 to close the communication switch circuit 142.

[0038] It should be noted that the communication interface assembly can be applied to a scanning device, that is, the interface slot is installed on the surface of the scanning device. Figure 2 , a protective shell 20 is provided on the surface of the interface slot, and the above-mentioned communication switch circuit 142 is installed on the protective shell 20, and the communication switch circuit 142 is located directly below the interface slot. Moreover, the communication switch circuit 142 is a push-type switch structure. A protrusion 122 is provided at one end of the above-mentioned preset cable 12 close to the second interface 121. When the second interface 121 of the preset cable 12 is connected to the interface slot to connect to the first interface, the installation position of the communication switch circuit 142 on the surface of the interface slot matches the installation position of the protrusion 122 on the surface of the second interface 121, so that the protrusion 122 can press the communication switch circuit 142 installed on the protective shell 20, so that the communication switch circuit 142 is closed; at this time, the above-mentioned scanning device can be connected to the external device through the communication interface component for wired connection. It is understandable that when the preset cable 12 is pulled out from the interface slot, the protrusion 122 is released from the communication switch circuit, and the communication switch circuit 142 is disconnected again, and the scanning device communicates wirelessly with the third-party device, thereby realizing automatic switching between wired and wireless.

[0039] In an optional embodiment, the protrusion is configured as a right-angle protrusion structure; see Figure 2 , a protrusion 122 with a right-angled protrusion structure is provided at the end of the second interface 121 of the preset cable 12; specifically, the protrusion 122 includes a first side and a second side, and the first side and the second side form a right-angle structure; the end of the first side relatively far from the second side is installed on the surface of the preset cable 12; the end of the second side relatively far from the first side can press the communication switch circuit to close it when the second interface 121 of the preset cable 12 is connected to the above-mentioned interface slot. It can be understood that the protrusion 122 can also be set to other structures, for example, the first side and the second side of the protrusion 122 can form a certain arc, etc., as long as it can ensure that the protrusion 122 can press the communication switch circuit 142 when the preset cable 12 is connected to the interface slot.

[0040] In the above-mentioned communication interface component, a specially customized preset cable is provided, and a protrusion is provided at the second interface of the preset cable, which is used to press the communication switch circuit on the surface of the interface slot when the second interface is connected to the interface slot and connected to the first interface in the slot, so that the communication switch can be automatically closed when the preset cable is inserted into the interface slot, thereby realizing automatic switching between wired communication mode and wireless communication mode, avoiding the problem of manually modifying the communication mode after plugging the cable into or out of the communication interface during the three-dimensional scanning process, resulting in the need to suspend the scanning process for a long time, making the three-dimensional scanning process too long, and effectively improving the efficiency of three-dimensional scanning and the convenience of operation.

[0041] In some embodiments, the communication interface assembly further includes an interface power module and a power switch circuit; the power switch circuit, when the communication switch circuit is closed, connects the communication interface assembly and the interface power module. The interface power module is used to provide external power supply for the USB device. Specifically, when the communication switch circuit is closed, the power switch circuit is turned off, and the USB device is powered by the external power supply; when the communication switch circuit is disconnected, the power switch circuit is turned on, and the USB device is powered by the internal power supply.

[0042] In some embodiments, the communication interface component also includes a signal transmission chip; wherein the signal transmission chip is connected to the first interface; the communication switch circuit is connected to the ID pin of the signal transmission chip, and the CPEN pin of the signal transmission chip is connected to the enable end of the power switch circuit; the output end of the power switch circuit is respectively connected to the VBUS end of the signal transmission chip and the VBUS end of the first interface.

[0043] Specifically, see Figure 3 ,Should Figure 3 The USB2.0 PHY chip in the device is the above-mentioned signal transmission chip; the USB2.0 PHY chip supports On-The-Go (OTG) mode, allowing USB devices to communicate directly with other USB devices without a host. The USB2.0 PHY is provided with an ID pin and a CPEN pin. Among them, the CPEN pin is directly connected to the EN pin of the power switch circuit, that is, the enable end, and then the input and output of the power VBUS signal can be controlled through the CPEN pin. The input terminal VIN of the power switch circuit is also connected to the above-mentioned interface power module to provide internal power supply. The output terminal VOUT of the power switch circuit is respectively connected to the VBUS terminal of the USB2.0 PHY chip and the VBUS terminal of the USB3.0 interface.

[0044] More specifically, when the ID pin on the USB2.0 PHY chip is at a high level, the CPEN pin outputs a low level, turning off the power switch circuit, the VBUS power supply is provided externally, and the USB is in slave mode; when the ID pin is at a low level, the CPEN pin outputs a high level, turning on the power switch circuit, the VBUS power supply is provided internally, and the USB is in host mode.

[0045] Furthermore, when a specially customized USB3.0 cable with a protrusion at the interface of the front side wall is inserted into the interface slot, the protrusion presses the communication switch circuit to close the communication switch circuit; when the communication switch circuit is closed, the ID pin level of the USB2.0 PHY chip is pulled high, and the USB device switches to the slave mode to achieve USB wired communication. When the above USB cable is unplugged, the protrusion is released to disconnect the communication switch circuit; when the communication switch circuit is disconnected, the ID pin level of the USB2.0 PHY chip is pulled low, and the USB device switches to the host mode to achieve wireless communication.

[0046] It should be noted that in actual use, when a USB wireless network or USB to Ethernet adapter is inserted, the above communication switch circuit is in the disconnected state by default. At this time, the ID pin is pulled low, and the USB device is in host mode to achieve wireless or Ethernet communication.

[0047] Through the above embodiment, by controlling the level of the ID pin on the signal transmission chip, the power supply direction of VBUS is controlled, thereby realizing wired and wireless switching of the power supply mode, further improving the flexibility of the device during the three-dimensional scanning process.

[0048] In some other embodiments, the above-mentioned communication switch circuit includes a first resistor, a second resistor and a preset switch; the first end of the first resistor is grounded, and the second end of the first resistor is connected to the first end of the preset switch; the first end of the second resistor is connected to the second end of the preset switch, and the second end of the second resistor is connected to the power switch circuit; the first end of the preset switch is also connected to the ID pin of the signal transmission chip.

[0049] Specifically, see Figure 3, the first end of the first resistor R1 is grounded, and the second end of the first resistor R1 is connected to the first end of the preset switch S1; the second end of the preset switch S1 is connected to the first end of the second resistor R2, and the second end of the second resistor R2 is connected to the power supply voltage VCC; the first end of the preset switch S1 is also connected to the ID pin of the USB2.0 PHY chip. It should be supplemented that the resistance values ​​of the first resistor R1 and the second resistor R2 can be set according to the actual application situation, and the resistance values ​​of the first resistor R1 and the second resistor R2 must meet the following conditions: the resistance values ​​of the two resistors should ensure that after the preset switch S1 is closed, the voltage division on the first resistor R1 is greater than the high level threshold of the ID pin on the chip, so that after the communication switch circuit is closed, the level on the chip ID pin can be pulled up.

[0050] Furthermore, the above-mentioned communication switch circuit also includes a protection circuit; in the present embodiment, the protection circuit can be realized by a transient voltage suppression diode; more specifically, the cathode of the transient voltage suppression diode TVS1 is connected to the first end of the first resistor R1, and the anode of the transient voltage suppression diode TVS1 is connected to the second end of the first resistor R1, that is, the transient voltage suppression diode TVS1 and the first resistor R1 are connected in parallel to protect the circuit from the impact of transient high-voltage spike pulses, thereby improving the safety and stability of the communication switch circuit.

[0051] Through the above embodiment, a communication switch circuit implementation method including at least two resistors and a preset switch is provided, and automatic switching of the communication mode is realized through the above simple circuit structure, ensuring a low-cost communication interface component implementation method.

[0052] This embodiment also provides a three-dimensional scanning system. Figure 4 is a structural block diagram of a three-dimensional scanning system according to an embodiment of the present application, such as Figure 4 As shown, the system includes: a scanning device 42, a terminal device 44 and a communication interface assembly 10 as described in any of the above embodiments; wherein the scanning device 42 is connected to the terminal device 44 through the communication interface assembly 10. The terminal device 44 refers to a third-party device that needs to communicate with the scanning device 42 during the scanning process. Specifically, when a preset cable is connected to the interface slot in the communication interface assembly 10, so that the protrusion provided on the preset cable presses the communication switch circuit installed on the surface of the interface slot, the communication switch circuit is closed, so that the communication mode between the scanning device 42 and the terminal device 44 is automatically switched to the wired communication mode.

[0053] Through the above-mentioned embodiment, a communication interface component that provides a specially customized preset cable is applied in the three-dimensional scanning system, which realizes the upgrade of the communication mode of the scanning device 42, so that it supports automatic switching between wired transmission and wireless transmission during the three-dimensional scanning process. The user can independently select the transmission mode according to the usage scenario, thereby effectively improving the scanning efficiency and operation convenience of the three-dimensional scanning system.

[0054] In some embodiments, the scanning device includes a main control chip; wherein the main control chip is connected to the signal transmission chip of the communication interface component and the first interface. Figure 3 The main control chip is a system on chip (SOC), which has a built-in USB2.0 ULPI interface and a USB3.0 PIPE3.0 interface. The USB2.0ULPI protocol is a protocol used for communication between USB controller and USB PHY, so the USB2.0ULPI interface in the main control chip also needs to be connected to an external USB2.0 PHY chip, which is used for the lowest level physical electrical signal conversion. The USB3.0 PIPE3.0 interface is directly responsible for USB3.0 communication. Among them, the USB2.0 PHY chip is the above-mentioned signal transmission chip, and the USB3.0 PIPE3.0 interface is the above-mentioned first interface.

[0055] Those skilled in the art should understand that the technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
