Click the blue text above 【AnTuTu】 to follow me Sharing technology hotspots every day! On March 2, Meizu not only launched the new version of Flyme 9 today but also surprisingly introduced the Flyme for Watch operating system. Regarding this Meizu smartwatch, it was officially announced last year that it would be released in Q4 … Read more
If you buy a new car today, it will almost certainly come with a “vehicle file” that records information throughout the car’s lifecycle. When a fault occurs, technicians can quickly identify the problem based on historical data. Many of us may not have as detailed a record of our own body’s “operational status” as we … Read more
I am Lao Wang, and I have been working in automation maintenance for 12 years in a factory. Today, I will show you how to use PLC to create something advanced—a vibration analysis early warning system. Although this sounds like a task for precision instruments, it can be effectively managed with a PLC. Last year, … Read more
Do you remember that project that kept me awake all night? A packaging production line, with the client pushing hard for results. I thought to myself, this is just a simple conveyor control, I can jump right in and write the program. But what happened? I spent three whole days debugging, with problems popping up … Read more
On the grand stage of modern industrial production, various automation devices resemble precision instruments, collectively playing a symphony of efficiency, accuracy, and safety. Core devices such as PLCs, sensors, encoders, inverters, and relays not only perform unique roles but also collaborate closely to ensure the smooth operation of the entire production process. Next, let us … Read more
Digital Twin technology, as one of the core technologies of the Industry 4.0 era, is profoundly changing the equipment debugging and operation and maintenance models in traditional manufacturing. For PLC engineers, Digital Twin technology provides a powerful tool that combines virtual and real environments, allowing them to complete debugging work in a virtual environment before … Read more
This depends on the specific model of the PLC. PLCs can be categorized into relay output, transistor output, and thyristor output. Relay-type PLCs can directly control contactors, while transistor and thyristor-type PLCs cannot directly control contactors. The maximum output current of relay-type PLCs is 2A, which can drive AC and DC loads. The allowable load … Read more
I still remember that hot summer three years ago when I received what seemed like a simple project—designing a constant pressure water supply system for an industrial park. At that time, I thought, isn’t it just a variable frequency drive paired with a few water pumps? Little did I know that this would take three … Read more
> At seven in the morning, the city awakens from its slumber. The traffic at the intersection flows like blood, and the traffic lights act as the “heart valves” controlling the flow. Have you ever wondered: why does the green light always turn red just after the vehicles pass? Why is there a continuous green … Read more
