[0037] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0038] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0039] Because the scanning control system cannot directly connect to the scanning execution device, various types of scanning control systems cannot directly control the scanning execution device. During the use of the scanning device, if it cannot match the signal types transmitted by various control terminals, the compatibility of the scanning device may be limited.

[0040] Based on this, the present application proposes a connection device, which includes a control module, a network interface module, a bus interface module, and a digital signal interface module. The network interface module, the bus interface module, and the digital signal interface module are respectively connected to the control module. The control module is used to convert the signal received by the network interface module into a signal received by the bus interface module or a signal that can be sent by the digital interface module, and convert the signal received by the bus interface module or the signal received by the digital interface module into a signal sent by the network interface module. Through the above connection, the connection device can quickly realize the connection between control terminals of various signal transmission types and scanning devices, meet the application requirements of different automation control systems with strong adaptability, greatly reduce the application difficulty of automation integration, and thus save costs.

[0041] Next, the connection device will be described in detail. Figure 1 It is a structural schematic diagram of a connection device provided in an embodiment of the present application.

[0042] Optionally, the connecting device includes: a control module, a network interface module, a bus interface module and a digital signal interface module.

[0043] Optionally, one end of the network interface module is used to connect to the scanning device, and the other end of the network interface module is connected to the control module.

[0044] Specifically, the network interface module and the scanning device can be connected via a shielded Category 6 network cable, and the control interaction commands sent by the scanning device can be transmitted via a communication protocol.

[0045] Optionally, one end of the bus interface module and one end of the digital signal interface module are respectively used to connect to the control terminal, and the other end of the bus interface module and the other end of the digital signal interface module are respectively connected to the control module.

[0046] The control terminal may be equipped with various types of automated control systems to send control signals to the scanning device, so that the scanning device performs scanning and other actions according to the control signals. The scanning device may be a three-dimensional scanner, a two-dimensional scanner, or the like.

[0047] Specifically, the bus interface module is connected to the control terminal via a bus, while the digital signal interface module is connected to the control terminal using a signal cable. The bus interface module can transmit control interaction commands sent by the control terminal through a communication protocol, while the digital signal interface module can transmit interaction command signals by switching on and off electrical signals.

[0048] Optionally, the control module is used to convert signals received by the bus interface module and the digital signal interface module into signals transmittable by the network interface module, and convert signals received by the network interface into signals transmittable by the bus interface module and the digital signal interface module.

[0049] Optionally, the control module is used to convert signals between the network interface module, the bus interface module, and the digital interface module. Specifically, the control module can use a pre-set software program to perform signal conversion.

[0050] It is worth noting that in Figure 1 The same scanning device can only be controlled by one control terminal. When the control terminal needs to be replaced, the bus interface module and digital signal interface module in the connection device need to be disconnected from other control terminals and reconnected to the replaced control terminal.

[0051] In this embodiment, the connecting device includes a control module, a network interface module, a bus interface module and a digital signal interface module. The network interface module, the bus interface module and the digital signal interface module are respectively connected to the control module. The control module is used to convert the signals connected between the network interface module, the bus interface module and the digital interface module, so as to quickly realize the connection between the control terminals of various signal transmission types and the scanning device, meet the application requirements of different automation control systems with strong adaptability, greatly reduce the application difficulty of automation integration, and thus save costs.

[0052] As an optional implementation manner, the signal accessed by the network interface module is a signal supporting transmission control / network protocol.

[0053] Optionally, different types of control terminals can send various types of control signals to the connecting device, and the connecting device can convert the control signals into signals supporting Transmission Control Protocol / Internet Protocol (TCP / IP) and send them to the scanning device.

[0054] As an optional implementation, the signal accessed by the bus interface module is a signal supporting the ModbusTCP protocol, EtherCAT protocol, PROFINET protocol and EtherNet / IP protocol.

[0055] ModbusTCP is a serial communication protocol, EtherCAT is a real-time Ethernet technology optimized for process data, and PROFINET and EtherNet / IP are Ethernet-based industrial communication protocols. These four protocols are applicable to information exchange and data transmission between different control terminals.

[0056] It is worth noting that the signals supported for conversion by the connection device include not only signals supporting ModbusTCP protocol, EtherCAT protocol, PROFINET protocol and EtherNet / IP protocol, but also signals of other scanning devices.

[0057] As an optional implementation manner, the digital signal interface module is connected to the control terminal via a signal cable.

[0058] The digital signal interface module can connect input and output (IO) digital signals.

[0059] In this embodiment, the signal accessed through the network interface module is a signal that supports the TCP / IP protocol, the signal accessed by the bus interface module is a signal that supports the ModbusTCP protocol, EtherCAT protocol, PROFINET protocol and EtherNet / IP protocol, and the digital signal interface module is connected to the scanning device through a signal cable, so that the connecting device can be connected to various scanning devices and control terminals, thereby supporting more and richer control commands sent by control terminals.

[0060] For example, the scanning device can only communicate via signals supporting the TCP / IP protocol, control terminal A can only communicate via signals supporting the Modbus TCP protocol, and control terminal B can only communicate via signals supporting the EtherNet / IP protocol. After control terminal A uses the connection device to control the scanning device to perform a scan, it can directly disconnect from control terminal A and connect to control terminal B to control the scanning device to perform the scan.

[0061] Optionally, Figure 2 This is a schematic diagram of the structure of another connection device provided in an embodiment of the present application. Figure 2 As shown, the connecting device further includes: a power module, which includes a power button and a power interface.

[0062] Optionally, the power button is connected to a first end of the power interface, and a second end of the power button is connected to the control module.

[0063] Optionally, the second end of the power interface is connected to an external power source.

[0064] The second end of the power interface is connected to an external power source via a power line. The external power source can be 220 volts AC.

[0065] Optionally, after the power button is triggered, the power interface and the control module are connected or disconnected.

[0066] As an optional embodiment, when a user begins using the connected device, they trigger the power button, which in turn triggers the control module to connect to the external power source via the power interface. While the power interface is connected to the control module, the current power on status is displayed according to a preset power display format. When the user stops using the connected device, they trigger the power button, which in turn triggers the control module to disconnect from the external power source via the power interface. While the external power source is disconnected, the power interface displays the current power off status according to a preset power display format.

[0067] Optionally, the power interface may include an indicator light for displaying the current power status in a preset power display format.

[0068] For example, when the power is on, the power display is preset to be green, and when the power is off, the power display is preset to be red.

[0069] As an optional implementation, the power button enters or exits the self-locking state when triggered.

[0070] Optionally, when the user begins using the connected device, the power button is triggered, and the power button enters a self-locking state, so that the power interface remains powered on, the connected device is powered on, and initialization configuration is completed. When the user stops using the connected device, the power button is triggered, and the power button exits the self-locking state, so that the power interface remains powered off.

[0071] In this embodiment, the connection device further includes a power module for controlling the power on and off of the connection device, thereby controlling the connection device.

[0072] As an optional implementation, Figure 2 As shown, the connecting device further includes: a reset module.

[0073] Optionally, the reset module is connected to the control module, and the reset module and the power module are triggered to trigger the control module to reset the configuration parameters.

[0074] Specifically, the reset module further includes: a reset button and a delay unit.

[0075] One end of the delay unit is connected to the reset button, and the other end of the delay unit is connected to the control module.

[0076] Optionally, the delay unit is used to determine whether the duration of triggering the reset button is greater than a preset reset duration.

[0077] Specifically, when the user needs to reset the parameters in the control module, the user can trigger the reset button and hold it for a certain period of time, which is longer than the preset reset time, then release the reset button, trigger the power button to disconnect the power of the connection device, and trigger the power button again to turn on the power of the connection device, thereby completing the reset of the configuration parameters of the control module.

[0078] It is worth mentioning that the delay unit can be implemented in software or hardware form to implement the delay function. Specifically, a program with a delay function can be set in the control module to perform the delay action, or the delay action can be performed in hardware form such as a timer.

[0079] As an optional implementation, Figure 3 This is a schematic diagram of an interface of a connection device provided in an embodiment of the present application. Figure 3As shown, the connection device is an aluminum alloy box structure, with a network interface module, bus interface module, digital signal interface module, power interface, reset button, and power button on the back. The digital signal interface module is above the network interface module and bus interface module, which are arranged side by side. The power interface, reset button, and power button are arranged side by side in that order at the bottom layer of the back of the connection device.

[0080] In this embodiment, the configuration parameters of the control module are reset by setting the reset module, thereby ensuring the normal use of the connection module.

[0081] As an optional implementation, the connecting device further includes: a display module, which includes: an interface status display unit, a power display unit, and an operation status display unit.

[0082] Optionally, the display module is connected to the control module.

[0083] Optionally, the interface status display unit is used to display the connection status of the network interface module, the bus interface module and the digital signal interface module.

[0084] Among them, the control module can use a pre-set software program to detect the connection status of the display network interface module, bus interface module and digital signal interface module, and control the display module to display the connection status of each interface according to the connection status of the display network interface module, bus interface module and digital signal interface module.

[0085] Specifically, the interface status display unit can display the connection status of the network interface module, the bus interface module and the digital signal interface module through multiple status indicator lights. A variety of different status display forms can be set to display the current status of each interface module.

[0086] As an optional embodiment, the interface status display unit includes 30 status display lights. When one of the 1st to 5th display lights is on, it indicates that the digital signal interface module is in the state of input signal, and the order of the display lights is the same as the order of the access signal in the digital signal interface module. For example, if the second access signal is in the digital signal interface module, the second display light is on. Similarly, when one of the 5th to 10th display lights is on, it indicates that the digital signal interface module is in the state of output signal. When one of the 10th to 15th display lights is on, it indicates that the network interface module is in the state of input signal, and when one of the 15th to 20th display lights is on, it indicates that the network interface module is in the state of output signal. When one of the 20th to 25th display lights is on, it indicates that the bus interface module is in the state of input signal, and when one of the 25th to 30th display lights is on, it indicates that the bus interface module is in the state of output signal.

[0087] As another optional embodiment, the interface status display unit includes 36 status display lights. When one of the 1st to 16th display lights is on, it indicates that the digital signal interface module is in the input signal state. When one of the 16th to 32nd display lights is on, it indicates that the digital signal interface module is in the output signal state. When the 33rd display light is on, it indicates that the network interface module is in the input signal state. When the 34th display light is on, it indicates that the network interface module is in the output signal state. When the 35th display light is on, it indicates that the bus interface module is in the input signal state. When the 36th display light is on, it indicates that the bus interface module is in the output signal state.

[0088] It is worth noting that the configuration of each status display light in the interface status display unit is pre-set, and the staff can set the status display form of each interface module according to actual needs.

[0089] Optionally, the power display unit is used to display whether the connection device is powered on.

[0090] Exemplarily, the power display unit may be a display light. When the connection device is powered on, the display light is on, and when the connection device is powered off, the display light is off.

[0091] Optionally, the operating status display unit is used to display the operating status.

[0092] Exemplarily, the operation status display unit may be a display light. When an error occurs during operation of the connection device, the display light turns on. When the connection device is freed from the fault state, the display light turns off.

[0093] In this embodiment, the connection status of the network interface module, the bus interface module and the digital signal interface module, whether the connection device is powered on and the operation status of the connection device are respectively displayed through the interface status display unit, the power supply display unit and the operation status display unit, thereby prompting the staff of the current status of the connection device so that the staff can perform corresponding operations according to the display content of each display unit.
