How to Define A DIY CNC Router

The definition of a DIY CNC router is bellow:  

A DIY CNC router can be defined as a router that is built and customized by users according to their personal needs and network environment by selecting, assembling and configuring corresponding hardware and software components.

This router not only meets user specific network requirements, such as higher network speed, stronger network coverage, more refined network management, but also provides a high degree of flexibility and customizability.

Users can deeply customize and optimize the router according to their own technical level and interests to achieve the best network performance and user experience.

DIY CNC routers emphasize user autonomy and creativity, allowing users to design and build the ideal network equipment according to their needs.

Applications＆Working Principles

Here are some basic knowledge of CNC Router which may lay a foundation for building a diy CNC Router:

Applications:

It is mainly concentrated in industrial and commercial environments where stable, efficient and reliable network connectivity is required.

1.Industrial equipment monitoring and control:

CNC routers are widely used in industrial sites to achieve remote monitoring and control of large industrial equipment such as CNC machine tools and cranes.

Through the 4G/5G network, the operating data of these devices can be uploaded to the data management center in real time, so that managers can keep abreast of the operating status of the equipment and make necessary adjustments and optimizations.

Once the device fails or is abnormal, the CNC router is able to quickly send an alert to the data management center for timely response and processing.

2.Intelligent parking Monitoring:

In the intelligent parking lot, the CNC router can connect the collector and other equipment to automatically collect the information of vehicles and the number of empty parking Spaces.

This information can be uploaded to the control center in real time through the CNC router, and synchronized to the cloud platform, so that users can query, reserve the remaining parking space and pay parking fees at any time through the mobile APP.

3.Cash register equipment monitoring:

In restaurants, retail and other places, CNC routers can be used as a backup of the wired network to ensure that the cash register equipment can still work normally when the network is unstable.

The stable network connection provided by the CNC router can ensure the smooth and efficient user payment process, reducing the case of payment delays or failures.

4.Medical Equipment Monitoring:

In medical places such as hospitals, CNC routers can be connected to medical equipment to transmit equipment operation data and patient information in real time.

Medical staff can check the operation of the equipment at any time through the computer, and adjust and optimize it as needed.

Working Principles:

The working principle of CNC routers can be summarized as the following key steps, which together ensure the efficient and accurate transmission of data in the network:

1.Receive data packets:

When a CNC router receives a packet from another network device, such as a computer, server, or other router, it first checks the header information of the packet.

The header information contains important information such as the destination IP address, which is crucial for the subsequent processing of the router.

2.Route lookup:

A CNC router has one or more Routing tables that record information about the best path to each destination in the network.

The router looks in the routing table based on the destination IP address in the packet to determine which exit Interface the packet should be forwarded through.

During the search, the router finds the record that best matches the destination IP address and determines the forward path.

3.Forward the packet:

Once the forward path and exit interface are determined, the router's Forwarding Engine forwards the packet from the input interface to the correct exit interface.

This process usually involves the encapsulation and de-encapsulation of the packet to ensure the integrity and security of the packet during transmission.

4.Update the routing table:

CNC routers update their routing tables periodically or according to network changes.

This can be done through static route configuration, dynamic routing protocols (such as RIP, OSPF, etc.), or other means.

Routing table updates ensure that routers are able to select the best path for packet forwarding, thereby improving network performance and efficiency.

5.Network isolation and access control:

CNC routers can also achieve network isolation and access control functions.

By configuring access control lists (ACLs) and other security policies, routers can restrict or allow communication between specific devices or networks.

This helps protect network security against unauthorized access and data breaches.

6.Data processing and forwarding decisions:

In the whole process, the CNC router will parse and process the packet according to the network protocol (such as IP, TCP/UDP, etc.).

It will make forwarding decisions based on protocol regulations and routing table information to ensure that the packet can accurately reach the destination.

7.Performance and stability optimization:

CNC routers typically employ a range of techniques and algorithms to optimize performance and stability.

This includes queue management, congestion control, load balancing and other mechanisms to ensure efficient data transmission and forwarding under high load and complex network environments.
