Description

A Modular Local Area Network Monitoring System Applied to 3D Printing Equipment

technical field

The utility model relates to the technical field of communication systems, in particular to a modularized local area network monitoring system applied to 3D printing equipment.

Background technique

3D printing refers to the manufacturing method of directly manufacturing parts driven by the three-dimensional data of parts based on the discrete-accumulation principle. It has the advantages of simplifying the processing procedure, the processing cycle has nothing to do with the complexity of the structure, the assembly of the finished product is free, and the complexity of the structure is unlimited. It is an important development direction of future manufacturing technology. At the same time, it meets the manufacturing needs of personalized, customized and small-quantity products. It is foreseeable that this technology will be further popularized in application fields such as personal families, large organizations and technical research.

The working method of the 3D printing equipment is as follows: the host computer uses slicing software to convert the STL model into machine codes, and then the host computer control software uses certain rules to send these machine codes to the 3D printing equipment one by one, when the 3D printing equipment converts all the machine codes one by one After execution, the manufacturing process ends.

However, in some scenarios, there are still many inconveniences in using 3D printing equipment, which hinders the popularization of 3D printing technology.

For individual home users, due to the limitations of price, required precision and difficulty of use, the 3D printing equipment they choose is often a desktop-level melt extrusion molding equipment (ie FDM3D printer). But this kind of equipment is slow to manufacture, noisy and smelly (when using ABS material). Therefore, the equipment is not suitable to be placed on the user's work and study desk, but is more suitable to be placed in a ventilated corner of the house, and the user can monitor the equipment through remote communication. Moreover, the working effect of desktop-level melt extrusion molding equipment is greatly affected by the environment (such as temperature, humidity, and wind speed). Individual home users often cannot adjust the manufacturing parameter settings according to the environmental data, and the performance of the equipment cannot be further developed.

For large organization users, the number of 3D printing equipment owned by enterprises or governments will be large. Therefore, centralized management of these devices is required.

Therefore, local area network monitoring and manufacturing parameter setting suggestions are the functions that 3D printing technology needs to truly popularize.

Detailed ways

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto.

As shown in Fig. 1, a modularized LAN monitoring system applied to 3D printing equipment includes a sequentially connected LAN monitor, a data transfer network, and a host computer, and the LAN monitor is connected to the 3D printing equipment.

As shown in Figure 2, the LAN monitor includes an environmental data acquisition module connected in sequence, a data processing board 2 and a serial port communication module 4, wherein the data processing board 2 is connected to the 3D printing device 9 through the serial port 1 and the interface 8, and the serial port communication module 4 connected to the data transfer network; the environmental data acquisition module includes a camera 10, a temperature and humidity sensor and a wind speed sensor 7; the environmental data acquisition module is used to record the environmental data where the 3D printing device 9 is located, and transmit it to the data processing board 2 The data processing board 2 is connected to the 3D printing device 9 through the serial port 1, and at the same time connected to the data transfer network through the serial port communication module 4; depending on the amount of data to be processed, the architecture of the data processing board 2 can be AVR, ARM or X86, etc.; The data processing board 2 is responsible for transmitting the environmental data and the instructions issued by the 3D printing equipment to the serial communication module 4 through the serial port signal, and accepts the instructions from the host computer from the serial port communication module 4, and sends the machine code in the instruction (directly command 3D The code of the printing device) is passed to the 3D printing device 9 through the serial port connection; the serial port communication module 4 is connected to the data processing board 2 through the serial port 3, and connected to the data transfer network through other signal transmission protocols 5 (which can be WIFI or wired network); the serial port The function of the communication module 4 is to transmit the instruction from the host computer to the data processing board 2, and the data uploaded by the data processing board 2 is transmitted to the host computer; the camera 10 is connected with the data processing board 2 through the interface 6.

The data transfer network includes sequentially connected routers, modems, and local area networks;

Described host computer is a kind of in computer, mobile phone, single-chip microcomputer;

The functions of the upper computer function software are virtual serial port, display of environmental data and data extraction and analysis. When the device is connected to the host computer through a serial port cable, the host computer will assign a serial port number (such as COM3) to the device, and the host computer control software will connect to the device by connecting the serial port number. If this system is used, the device is not directly connected to the host computer through the serial port, so the host computer function software is required to virtualize the non-serial port connection mode as a serial port connection, and let the host computer assign a serial port number, and the host computer control software can communicate with the serial port number through this serial port number. Device docking. Environmental data acquisition modules such as cameras and temperature and humidity sensors are not available in the original 3D printing equipment. The upper computer does not have a window to display the corresponding data, so the upper computer functional software needs to have an interface to display the corresponding environmental data. The data extraction analysis is to extract the environmental data and setting data stored in the server, and provide the user with recommended manufacturing parameters by analyzing the environmental data or help the user understand the relationship between the manufacturing setting parameters and the printing effect through the comparison between the environmental data and the setting data. contact. In addition, the upper computer can be a computer, mobile phone or even a single-chip microcomputer, and the form of functional software on different platforms may be different.

As shown in Figure 5, the environmental data is the data that neither the host computer nor the 3D printer originally generated. The environmental data is generated by the environmental data acquisition module on the monitoring manager, and the data processing board of the monitoring manager analyzes and arranges it after receiving it, and the serial port communication module converts the format of the data from the serial port to the TCP protocol, and transmits it to the host computer.

As shown in Figure 6, the printer status information is generated by the printer and originally transmitted directly to the host computer. However, the utility model transmits the status information to the upper computer through the local area network. The monitoring manager reads the status information, and the serial port communication module converts the data format into the TCP protocol, and finally reaches the host computer.

As shown in Figure 7, the machine code is the command code generated by the host computer, which was originally sent directly to the 3D printer by the host computer. And the utility model is to send the machine code from the upper computer to the 3D printer through the local area network. The serial port communication module converts the TCP data format into a serial port, and the monitoring manager sends the machine code to the printer.

Specifically:

The data transfer network is a data transmission network using the TCP/IP protocol, which is a very mature part of the technology directly used by this system. Figure 3 shows a schematic diagram of a typical data transfer network when individual home users use the system. If the signal "converted data protocol A" released by the leftmost router is WIFI, then you only need to configure the LAN monitor to connect to the home WIFI, and the host computer can automatically address and find the LAN monitor.

The internal structure and connection mode of the LAN monitor are shown in Figure 2. The serial port 8 of the 3D printing device is originally connected to the host computer through the USB interface. When using the system, you only need to insert the USB plug into the serial communication interface A1 of the data processing board. Then configure the monitoring manager to connect to the data transfer network through the converted data protocol A5 (such as WIFI, Ethernet, etc.).

The interface of the upper computer function software is shown in Figure 4. The function software is associated with the control software of the upper computer. When using it, you only need to open the function software of the upper computer to open the control software of the upper computer synchronously. Then the interface frame of the functional software will be automatically locked with the interface frame of the control software, thus providing the user with an integrated upper computer software environment. In one of the host computer function software interface designs, the software is divided into three functions, namely real-time video monitoring, presentation of environmental data, suggestions for manufacturing parameter settings, and extraction and analysis of historical data.

The following are two typical examples of the application of the utility model system.

For individual home users, they can purchase this system when they feel necessary after using the 3D printing equipment. For these users, using this system requires: purchase a LAN monitor (including an environmental data acquisition module, a data processing board, and a serial port communication module), configure it to connect to home WIFI, and connect the serial cable of the 3D printing equipment LAN monitor to Go to the 3D printing device and install the host computer function software. When in use, the user can place the 3D printing device in a ventilated corner of the house so that it will not disturb the user when working. Users can completely monitor the operation of the equipment on any host computer that can access the Internet, and obtain the recommended process parameter settings under the current equipment environment. Users can initiate printing remotely in the office or school and monitor it at any time. After the processing is completed, the user can remove the finished product from the device.

For enterprises, governments and other users who have a large number of 3D printing equipment, they can introduce this system when they need to manage these equipment in a unified manner. The use of the system requires: purchase a LAN monitor corresponding to the number of devices, and connect similarly to the above-mentioned personal family situation. When used, people within an organization can uniformly manage 3D printing equipment. In addition, users can upgrade, add, transfer or uninstall system modules at any time according to their own needs, which greatly reduces the cost of equipment or system upgrades.
