Implementing Kalman filtering for detecting and tracking the position of objects based on MATLAB GUI. Detect the center and maximum radius of the car, and perform morphological processing on areas with significant differences from the background difference. Use bubble sort to rank the target areas from largest to smallest. The program has been debugged and … Read more
![Innovative Idea: Communicating Between PLCs Without RS485 or Ethernet for Multi-Data Transmission ~ [With Tutorial]](https://boardor.com/wp-content/uploads/2026/01/e9cefc15-1150-4fc8-8a56-6431bbbbcdf0.jpg)
Last night, unable to sleep, I had a sudden idea: how can PLC1 communicate with PLC2 without RS485 or Ethernet if we need to transmit multiple data? Thus, I came up with the following hypothesis and experiments: Idea: If PLC1 oscillates at a certain frequency AND outputs data 0/1, isn’t that a way to output … Read more
Douyin commands are a way to quickly access Douyin from other platforms. Many friends have complained: someone sent them a Douyin command on WeChat, but they clicked for a long time with no response. This is mostly not an issue with the command itself, but rather with how you are trying to open it. This … Read more

How do I set up an HTTP proxy in my browser? Looking at a bunch of parameters makes … Read more
Introduction After completing data analysis, how to quickly generate high-quality graphs suitable for SCI papers is a challenge many researchers face. Relying solely on manual parameter adjustments can lead to significant time wastage. This article shares a Python script that can generate 18 common research graphs with one click, primarily using the Matplotlib and Seaborn … Read more
Hello readers, in the previous article, we learned about conditional statements and loop statements in Python. In this article, we will explore mutable objects, immutable objects, and comprehensions in Python. 1.Mutable and Immutable Objects Mutable objects: After a variable is created, modifying its content does not change the identity of the object (identity remains unchanged, … Read more
