Detailed Description
As described above, in the prior art, when 3D printing is performed, a file to be printed is usually exported from a local computer to a usb disk, and then the usb disk is inserted into a 3D printer to perform a print job, however, the 3D printing is performed by adopting the 3D printing mode, and the operation process is complicated.
In the embodiment of the invention, the 3D printing device sends the identification information of the 3D printing device to the data processing device. And the data processing device sends a connection request to the 3D printing device after receiving the identification information of the 3D printing device. The 3D printing device can establish communication connection with the data processing device according to the received connection request so as to carry out subsequent data transmission, and the data processing device can directly send the file to be printed to the 3D printing device without transferring the file to be printed to the 3D printing device through the USB flash disk, so that the convenience of 3D printing operation can be improved.
In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the following detailed description of the embodiments of the present invention refers to the accompanying drawings.
Referring to fig. 1, a flowchart of a method for connecting a 3D printing device according to an embodiment of the present invention may specifically include the following steps.
And step 11, transmitting the identification information of the 3D printing device to a data processing device.
In a specific implementation, the identification information of the 3D printing device is sent to the data processing device when at least one of the following occurs.
In an embodiment of the present invention, after detecting that the 3D printing device is powered on, identification information of the 3D printing device is sent to the data processing device.
In another embodiment of the present invention, after receiving the identification information of the data processing apparatus transmitted by the data processing apparatus, the identification information of the 3D printing apparatus is transmitted to the data processing apparatus. And the data processing device is internally provided with three-dimensional data processing software, and when the three-dimensional data processing software is detected to be started, the identification information of the three-dimensional data processing device is sent to the 3D printing device.
In yet another embodiment of the present invention, the identification information of the 3D printing apparatus is transmitted to the data processing apparatus when a change in a protocol (Internet Protocol, IP) address of an interconnection between networks of the 3D printing apparatus is detected.
In a specific implementation, the identification information of the 3D printing device may be transmitted in various manners. For example, a first user datagram protocol (User Datagram Protocol, UDP) broadcast is sent to the data processing apparatus, in which first UDP broadcast identification information of the 3D printing apparatus is included.
UDP is a connectionless transport layer protocol in the open systems interconnection (Open System Interconnection, OSI) reference model that provides a transaction-oriented simple unreliable information transfer service.
UDP, which is used in networks to process data packets as the TCP protocol, is a connectionless protocol. In the OSI model, at the fourth transport layer, it is at the upper layer of the IP protocol. UDP does not provide for packet grouping, assembling, and not ordering packets. After the message is sent, whether the message arrives safely and completely cannot be known. UDP is used to support network applications that require data to be transferred between computers, and many client/server mode network applications, including web video conferencing systems, require the use of the UDP protocol. Like the well-known TCP (transmission control protocol) protocol, the UDP protocol is located directly at the top layer of the IP (internet protocol) protocol. According to the OSI (open systems interconnection) reference model, both UDP and TCP belong to the transport layer protocol. The main function of the UDP protocol is to compress network data traffic into packets. A typical packet is a unit of transmission of binary data. The first 8 bytes of each packet are used to contain header information, and the remaining bytes are used to contain specific transmission data.
In a specific implementation, the identification information of the 3D printing device includes: an IP address of the 3D printing device, a physical (MAC) address of the 3D printing device, a type of the 3D printing device. In practical application, according to the practical application scenario, the identification information of the 3D printing device may further include at least one of the following: the machine model of the 3D printing device, the machine code of the 3D printing device, the machine name of the 3D printing device, etc. For example, the identification information of the 3D printing apparatus includes: IP address, MAC address, 3D printing device, number 001.
When the IP address of the 3D printing device changes, even if the 3D printing device sends the identification information or other information of the 3D printing device through a new IP address, the data processing device can still determine whether the 3D printing device is the 3D printing device which is connected before according to the physical address in the identification information of the 3D printing device. The data processing apparatus may refresh the IP address of the device in the database to obtain the 3D printing apparatus having the new IP.
And step 12, receiving a connection request sent by the data processing device.
In a specific implementation, after receiving the identification information of the 3D printing device, the data processing device may analyze the obtained identification information of the 3D printing device, and confirm the identity of the 3D printing device. After the identity confirmation of the 3D printing apparatus passes, a connection request is generated. The IP address of the 3D printing device is acquired from the identification information of the 3D printing device. And the data processing device sends a connection request through a preset port after acquiring the IP address of the 3D printing device.
And step 13, establishing communication connection with the data processing device.
In a specific implementation, after receiving a connection request sent by the data processing device, a communication connection with the data processing device is established.
In one embodiment of the invention, a socket is used to establish a communication connection with a data processing device.
After the communication connection is established, data transmission with the data processing device is possible.
As is clear from the above, the identification information of the 3D printing apparatus is transmitted to the data processing apparatus. And the data processing device sends a connection request to the 3D printing device after receiving the identification information of the 3D printing device. The 3D printing device can establish communication connection with the data processing device according to the received connection request so as to perform data transmission, and the data processing device can directly send the file to be printed to the 3D printing device without transferring the file to be printed to the 3D printing device through the USB flash disk, so that the convenience of 3D printing operation can be improved.
In a specific implementation, in order to improve data security in a communication process, in an embodiment of the present invention, a packet may be set for a data processing apparatus that allows connection, and when identification information of the 3D printing apparatus is sent in a broadcast manner, a broadcast group is set, that is, the data processing apparatus and the 3D printing apparatus bind the same port number. The 3D printing device sends the identification information of the 3D printing device to the data processing devices in the same broadcasting group, and only the data processing devices in the same broadcasting group can receive the identification information of the 3D printing device.
In a specific implementation, in order to improve the security of the communication connection with the data processing device, in an embodiment of the present invention, the connection request includes authentication information, where the authentication information is used to authenticate the identity of the data processing device. After receiving a connection request sent by the data processing device, acquiring authentication information in the connection request, and establishing connection with the data processing device after confirming that the authentication information is correct. The authentication information is preset, can be in the form of an account number and a password, and can also be a key in other modes.
In a specific embodiment, the 3D printing device periodically sends a heartbeat packet to the data processing device after establishing a communication connection with the data processing device, so as to inform the data processing device of its own online status. The 3D printing apparatus may transmit the heartbeat packet to the data processing apparatus at a predetermined cycle, or may transmit the heartbeat packet to the data processing apparatus non-periodically according to the set transmission condition. When the heartbeat packet is periodically transmitted, the transmission period may be set according to actual needs.
The data processing device receives the heartbeat packet to learn the online condition of the connected 3D printing device. And when the data processing device does not receive the heartbeat packet within a preset first time period, the connection is considered to be wrong, and the connection with the 3D printing device is automatically disconnected so as to reestablish the connection with the 3D printing device, wherein the first time period is longer than the heartbeat packet sending period of the 3D printing device.
In a specific implementation, the steps of the connection method of the 3D printing device may be performed by the 3D printing device, or may be performed by a server component provided in the 3D printing device.
In order to facilitate better understanding and implementation of the embodiments of the present invention by those skilled in the art, the embodiments of the present invention further provide a control method of a data processing apparatus.
Referring to fig. 2, a flowchart of a control method of a data processing apparatus in an embodiment of the present invention is provided, and the method may specifically include the following steps.
And step 21, receiving the identification information of the 3D printing device sent by the 3D printing device.
In a specific implementation, the received identification information of the 3D printing device may be sent by the 3D printing device through a first UDP broadcast, or may be sent through other manners.
In the embodiment of the invention, the data processing device can also be provided with a broadcast shield, and the shielded broadcast can not be answered, so that the network resource overhead can be saved.
Step 22, obtaining the IP address of the 3D printing device from the identification information of the 3D printing device.
In a specific implementation, after receiving the identification information of the 3D printing device, the identification information of the 3D printing device is parsed, and the 3D printing device is confirmed. And confirming that the received identification information of the 3D printing device is sent by the legal 3D printing device, and acquiring the IP address of the 3D printing device from the identification information of the 3D printing device.
And step 23, according to the acquired IP address of the 3D printing device, sending a connection request to the 3D printing device so as to establish communication connection with the 3D printing device.
In a specific implementation, according to the acquired IP address of the 3D printing device, a connection request is sent to the 3D printing device. The connection request is generated after receiving the identification information of the 3D printing apparatus. When the 3D printing apparatus receives the connection request, the 3D printing apparatus and the data processing apparatus may establish a communication connection through a socket (socket).
In an embodiment of the present invention, in order to improve the security of communication with the 3D printing apparatus, the authentication information of the data processing apparatus is included in the connection request. The 3D printing apparatus may verify whether the data processing apparatus is a legitimate device according to the authentication information. In addition, because the identity verification information is sent to the 3D printing device along with the connection request, the communication safety with the 3D printing device is improved, the user does not need to input the identity verification information when connecting each time, the identity verification information is automatically sent to the 3D printing device along with the connection request, and the convenience and the speed of connection are improved when the 3D printing device is connected.
By adopting the scheme, after the identification information of the 3D printing device is received, the connection request is actively sent to the 3D printing device so as to establish communication connection with the 3D printing device, facilitate the follow-up data transmission of the file to be printed, and improve the convenience of printing operation.
In a specific implementation, before receiving the identification information of the 3D printing device sent by the 3D printing device, after detecting that the three-dimensional data processing software in the data processing device is started, the identification information of the data processing device is sent to the 3D printing device. After the three-dimensional data processing software is started, the identification information of the data processing device is sent to the 3D printing device, and the 3D printing device is informed of being started at present so as to automatically seek communication connection with the 3D printing device, so that the data processing device can automatically seek an online 3D printing device when the three-dimensional data processing software installed on the data processing device is started so as to facilitate the automatic connection of the next step.
In an embodiment of the present invention, when it is detected that the three-dimensional data processing software in the data processing apparatus is started, a second UDP broadcast is sent to the 3D printing apparatus, where the second UDP broadcast includes identification information of the data processing apparatus.
In an embodiment of the present invention, the identification information of the data processing apparatus may include at least one of the following: the IP address of the data processing device, the physical address of the data processing device, the type of data processing device, etc. According to the actual application scenario, the data processing device may further include: machine model number, machine code, machine name, etc. of the data processing apparatus.
In a specific implementation, after the data processing device establishes a communication connection with the 3D printing device, the heartbeat packet sent by the 3D printing device may also be received.
In an embodiment of the present invention, when the heartbeat packet is not received within a preset first duration, the communication connection with the 3D printing device is disconnected, and the communication connection with the 3D printing device is re-established.
For example, when the 3D printing apparatus transmits a heartbeat packet to the data processing apparatus at a cycle of 30 seconds. When the data processing apparatus does not receive the heartbeat packet within 1 minute, it is considered that the connection with the 3D printing apparatus has been made wrong. The data processing device actively disconnects the communication connection with the 3D printing device and seeks to establish a communication connection again with the 3D printing device by sending identification information or a connection request of the data processing device to the data processing device. If the communication connection with the 3D printing device is not successfully established, the method is tried again. If the number of times that the data processing device attempts to reestablish connection with the 3D printing device reaches the preset number of times, the data processing device fails to establish communication connection with the 3D printing device, and the data processing device thoroughly disconnects the connection with the 3D printing device.

And after the data processing device receives the identification information of the 3D printing device, analyzing the identification information to obtain the IP address of the 3D printing device, and after the identification information is determined to be the 3D printing device in the same broadcast group, sending a connection request to the 3D printing device by utilizing a preset port and authentication information, and establishing connection with the 3D printing device by using a socket.
And after the data processing device detects that the three-dimensional data processing software installed on the data processing device is started, transmitting a second UDP broadcast. If the 3D printing device receives the second UDP broadcast sent by the data processing device and confirms that the three-dimensional data processing software installed on the data processing device is started, the 3D printing device sends the first UDP broadcast to the data processing device and informs the data processing device of the identification information of the 3D printing device.
The 3D printing device sends out a heartbeat packet every 30 seconds, proving that the device is still online. In addition to normal network disconnection, communication connection disconnection caused by other conditions may be immediately notified by both the 3D printing apparatus and the data processing apparatus. In addition, when no heartbeat packet is received in the data processing device within 1 minute, the connection is considered to be wrong, the connection is actively disconnected first, then the automatic connection is carried out for a plurality of times, and if the connection is completely disconnected after a plurality of times of connection attempt failures.
Because the MAC address is unique, when the IP address changes, the data processing apparatus can still determine which 3D printing apparatus is the previous one through the MAC address in the packet sent by the new IP address, and refresh the IP address of the 3D printing apparatus in the database (e.g. using the sqllite database).
