Hello everyone, I am your old friend— Sister Fang , a senior author focused on PLC programming and industrial automation teaching!
Today, let’s talk about a particularly “high-end” topic: The application scenarios of PLC combined with artificial intelligence technology DeepSeek in the chemical industry .
Don’t worry, Sister Fang will use simple and easy-to-understand language to make this seemingly complex technology simple and interesting, so you can easily understand it!

Why combine PLC and DeepSeek?
First, let me ask everyone a question: What is the most troublesome thing in chemical production? The answers may vary, but they generally include the following points:
- Equipment failures often catch people off guard, leading to long downtime and significant losses.
- Production efficiency is difficult to improve, relying on experience for process optimization, with limited efficiency gains.
- Product quality is hard to stabilize, and occasionally there are defective products or even accidents.
While traditional PLCs (Programmable Logic Controllers) can solve some of these problems, their limited logical control and computational capabilities often fall short in the complex chemical production environment.
So, DeepSeek has arrived!
This domestic AI model, with its powerful algorithmic and data analysis capabilities, can enhance PLCs, making chemical production smarter and more efficient.
Today, Sister Fang will show you what this combination can actually do!

DeepSeek empowering PLC: What has changed?
Traditional PLCs excel at logical control, such as “if the equipment temperature exceeds 60℃, then start the cooling system.”
However, when faced with complex environments, such as predicting whether equipment is about to fail or optimizing production processes, PLCs can seem “rigid”.
DeepSeek can enable PLCs to have “thinking” capabilities through data learning and intelligent analysis .
In simple terms, it’s like giving PLCs a smart “external brain”.
Next, let’s look at how DeepSeek changes the performance of PLCs through three key capabilities:
1. Equipment failure prediction and diagnosis
Chemical equipment often encounters issues, such as abnormal pump vibrations or valve blockages.
Traditional PLCs can only issue alarm signals after a failure occurs, leading to untimely repairs and production stoppages.With DeepSeek’s addition : By collecting a large amount of historical and real-time operational data, DeepSeek can analyze “early signals” of equipment failure, such as the pump’s vibration amplitude gradually exceeding the normal range, predicting possible failures in advance.
This allows maintenance personnel to prepare in advance, greatly reducing equipment downtime.
For example : In a chemical plant’s reactor, DeepSeek can analyze slight changes in temperature and pressure to determine whether the catalyst is failing, prompting operators to replace the catalyst in advance to avoid production accidents.
2. Production efficiency optimization
In chemical production, coordination between equipment often relies on human experience, such as how to adjust the conveyor belt speed to match the reaction speed, or how to optimize the heating furnace temperature to improve reaction efficiency.With DeepSeek’s addition : It can analyze production data to find the best operating parameters.
For instance, if the optimal reaction temperature range for a chemical device is 200-220℃, DeepSeek can continuously adjust the temperature based on real-time data to keep the reaction efficiency at its highest value.
For example : In a multi-stage distillation tower of a chemical plant, DeepSeek optimized the distillation process by analyzing feed flow rates and temperature distributions within the tower, improving purity while saving energy costs.
3. Product quality control
The quality of chemical products is often affected by various factors, such as temperature and raw material ratios.
Traditional PLCs can only perform simple monitoring and alarming, making dynamic adjustments difficult.With DeepSeek’s addition : It can monitor production indicators in real-time, such as liquid concentration and product purity.
When deviations are detected, it can automatically adjust equipment parameters to keep the production process within high-quality ranges.
For example : In the production of food additives, DeepSeek can monitor the concentration and purity of each batch of products in real-time, automatically adjusting the ingredient ratios to reduce defect rates and improve product stability.

Exploring application scenarios: The combination of PLC and DeepSeek in the chemical industry
1. Intelligent energy consumption management
In chemical plants, energy costs are a significant expenditure.
DeepSeek can analyze equipment operation data and production loads to dynamically adjust equipment power, avoiding energy waste.
For example, during the operation of a heating furnace, DeepSeek can adjust the heating power according to the production rhythm to reduce energy consumption.
2. Optimized control of complex processes
Chemical production processes are often very complex, such as multiple reactors working in coordination.
DeepSeek can analyze production data to find the best collaboration methods for each piece of equipment.
For example, in an ethylene cracking unit, DeepSeek can optimize the operating parameters of the cracker to increase yield while reducing by-products.
3. Data-driven safety assurance
Safety in chemical production is very important.
DeepSeek can monitor equipment operating status in real-time to detect safety hazards in advance.
For example, when detecting abnormal vibration amplitudes in a certain piece of equipment, DeepSeek can immediately issue a warning, helping operators take timely measures to avoid accidents.

Learning direction for beginners: How to get started?
If you are a beginner in PLC programming and want to learn how to combine AI technologies like DeepSeek with PLCs, Sister Fang offers the following suggestions:
- Master the basic programming languages of PLCs : such as Ladder Diagram (LD) or Structured Text (ST).
- Understand the basics of AI : Learn simple machine learning algorithms and data analysis methods.
- Learn industrial communication protocols : such as Modbus and OPC UA, which are the bridges for communication between PLCs and DeepSeek.
- Practice hands-on : Work on small projects, such as using DeepSeek to optimize a simple temperature control system.

Debugging and considerations
In practical applications, the combination of PLC and DeepSeek may encounter some issues, such as data communication delays or inaccurate model predictions. During debugging, Sister Fang suggests:
- Start with small-scale testing : First simulate tests in a laboratory environment to verify DeepSeek’s predictive capabilities.
- Monitor model outputs : Ensure that DeepSeek’s predictions align with actual conditions to avoid “model hallucinations” (i.e., predictions deviating from reality).
- Optimize data collection : Ensure sensor data is accurate and reliable to prevent erroneous data from affecting model judgments.

Summary and outlook
Today, Sister Fang explored the application scenarios of PLC combined with DeepSeek in the chemical industry with everyone.
We learned that this combination can not only improve production efficiency and reduce energy consumption but also significantly enhance product quality and safety.
Although this technology is still developing, it has already opened new pathways for the intelligent upgrade of the chemical industry.
Sister Fang’s message : Learning PLC and industrial automation is not difficult; the key is to maintain curiosity, practice more, and engage in hands-on activities.
I hope everyone can gain a deeper understanding of this cutting-edge technology through today’s sharing and feel confident about future learning!
