Abstract in Chinese: During the testing process of fault injection at the system level of an aircraft using the 1553B bus, common engineering issues are often encountered, such as difficulties in ensuring the real-time transmission of signals during the 1553B injection process, challenges in obtaining or frequently changing bus interface protocols, and onboard software that … Read more
Hello everyone, today we will discuss the principles of RS485 communication, why matching resistors need to be added when the communication line is long, how to add them, how to adjust the value of the matching resistors, their impact on the output waveform, and why matching resistors should be added at both ends, among other … Read more
01 HC-12 Communication Module 1. Introduction These are two HC-12 wireless communication modules just assembled. The LED can display the number of bytes received. Now let’s go outside to the square to check the communication distance. Its communication baud rate is 9600, let’s see what the corresponding communication distance is in this case. 2. Measurement … Read more

01 Output Forms of Sensors 1. Digital Output Type Digital output primarily includes three forms: RS232, RS485, and wireless transmission. The specific digital output type is chosen based on the actual communication distance and the complexity of the terrain. RS232 output is generally suitable for short-distance transmission within 15 meters and has weak electromagnetic interference … Read more
