Based on the industrial scenarios previously focused on regarding the selection, adaptation, and installation of digital interfaces for hot runners, the core challenges of real-time data acquisition from hot runner sensors are concentrated in the following aspects:
Strong Electromagnetic Interference Challenge: High-power heating coils around the hot runner generate strong electromagnetic radiation, which easily interferes with the weak signal transmission of sensors, causing temperature data jumps, packet loss, and a significant decrease in acquisition accuracy.
High-Temperature Operating Condition Limitations: The ambient temperature in the hot runner environment can reach over 80℃. Ordinary acquisition modules are prone to temperature drift during long-term operation, leading to data deviations and even direct hardware failure.
Multi-Node Synchronization Challenges: Multi-loop hot runners can contain dozens of sensors. Achieving millisecond-level synchronous acquisition of temperature data places extremely high demands on the bandwidth and scheduling capabilities of the acquisition system, making data asynchrony issues highly likely.
Waving Space Constraints: The internal space of the hot runner control cabinet is compact, making the arrangement of numerous sensor signal lines difficult and prone to cross-interference, further increasing the difficulty of stable data acquisition. These challenges require targeted anti-interference and high-temperature resistance designs to ensure the real-time performance and accuracy of data acquisition.
