0. Introduction In this article, we will introduce the encryption and decryption in .NET Core. In web applications, user passwords are stored as MD5 hashes. In other cases, encryption and decryption functionalities are also used. Common encryption algorithms are divided into symmetric and asymmetric encryption. Symmetric encryption means that the encryption key and the decryption … Read more

Introduction In the field of automation, there are devices that cannot be operated manually, such as high-pressure gates and corrosive liquid valves. Typically, we use computer software to control these devices through a combination of PC-based host software and a microcontroller. Project Requirements Design a controller with four relays that can be controlled via software … Read more
Expand Infinite Possibilities Alabi Company is a pioneer in the automotive OTA field. Currently, most automotive companies’ OTA platforms are either developed by Alabi or modeled after it. The reason for this phenomenon is still due to the previously discussed vehicle technology principle of “winner takes all” and “advanced one year, reaps once,” which can … Read more
1 What is MQTT? MQTT (Message Queuing Telemetry Transport) is an instant messaging protocol developed by IBM, which could become an important part of the Internet of Things (IoT). MQTT is a messaging protocol based on a binary message publish/subscribe programming model, and has now become an OASIS standard. Due to its simplicity, it is … Read more
1. RW6The robot can only jog in manual mode using the teach pendant (or through Webservice1.0 to jog the robot, but the teach pendant must be manually enabled continuously) 2. RW6If you want to jog the robot from the PC, you typically writeMoveL commands in RAPID and control the variables from the PC for pseudo … Read more

Introduction: MQTT is an instant messaging protocol developed by IBM. MQTT is a connection protocol aimed at M2M and the Internet of Things, utilizing a lightweight publish and subscribe message transmission mechanism. You can directly download the source code of the MQQT service from GitHub, source code address: https://github.com/mqtt/mqtt.github.io/wiki/libraries Main Content: Official Document Translation: The … Read more
The previous two articles discussed the basic decomposition process of the MQTT protocol. This chapter mainly discusses the implementation of specific messages. Since the message handling specifications are quite similar, we will introduce the Connect and Publish messages, which are relatively complex in the MQTT protocol. Understanding the protocol analysis of these two messages will … Read more
In industrial production, precise temperature control often directly relates to product quality and production efficiency. As an engineer with 15 years of experience in industrial automation control, I understand the importance of temperature control systems. Today, I will share how to build a high-precision real-time temperature control feedback system. System Components and Features Before implementing … Read more
