Today, industrial acoustic imaging technology is changing this reality. By capturing the sound field distribution through a microphone array and generating a real-time heat map of the sound source, acoustic cameras can pinpoint the location of the abnormal sound source, shortening troubleshooting times from hours to mere minutes.

常見旋轉機械故障及其聲學特徵

特徵噪聲是由早期故障產生的，通常表現為高頻聲信號和微振動。使用聲學攝影機，我們可以直觀地捕捉四種典型機械故障的噪音：

軸承損壞：通常表現為高頻摩擦或週期性敲擊。
葉片不平衡：風扇或泵浦中的質量分佈不均勻導致特定頻率的旋轉噪音。
葉片未對準：安裝偏差會導致運作期間週期性的氣動噪音或機械摩擦。
Roller Abnormality: Wear in conveyor belts or rolling mills leads to irregular friction and collision sounds.

超越表面：使用「峰度」和「波峰」進行早期預警Factor"

僅僅「看到」聲音是不夠深入的；真正的預測性維護。在的機械噪音診斷系統中，我們引入了兩個關鍵的統計指標：波峰因數 (CF) 和峰度。 (CF)：振幅比，告訴您最大脈衝有多大。 c13f49d3bdddca11705c77ea追蹤故障的聲學演進：

早期故障階段：峰度急劇上升並首先發出警報。 RMS（均方根）振動值顯示任何明顯變化之前，稀疏、尖銳的脈衝就會大大改變統計分佈。發展故障階段：隨著脈衝變得更強和更頻繁，兩個指標都會上升。 5599b8c13f49d3bdddca11705c77ea透過持續追蹤這些關鍵指標，工程師可以準確地確定設備的確切生命週期階段故障.245599b8c13f49d3b dddca11705c77ea標準化檢測工作流程：Hertzinno的最佳實踐

By continuously tracking these key indicators, engineers can accurately determine the exact lifecycle stage of the equipment fault.

Standardized Inspection Workflow: Hertzinno's Best Practices

To obtain the most accurate mechanical abnormal noise data in complex industrial sites, the Hertzinno team has summarized a standardized setup guide based on the new generation HA3 series (equipped with a 144-channel array and ultra-wideband capabilities):

Parameters: Set the detection band to 20 ~ 40kHz (M mode). This high-frequency range effectively filters out most low-frequency background noise in the workshop, accurately extracting the high-frequency characteristics of mechanical friction.
Mode Selection: Select the dedicated "Mechanical Noise" mode in the system.
Data Capture: Aim at the suspicious equipment and take at least 5 photo pictures or a 5s video to ensure the system captures enough comprehensive voiceprint data for subsequent CF and Kurtosis calculations.

Moving Towards 24/7: Online Voiceprint Monitoring Systems

For core assets where the cost of downtime is extremely high or the operating environment is hazardous, Hertzinno also offers an online voiceprint monitoring system.

This system can provide 24/7 monitoring of acoustic dimensions, track voice change trends, identify environmental sound characteristics, and deliver enhanced scenario adaptability for a fully automated predictive maintenance solution.

Conclusion Industrial acoustic imaging is not just a "camera that sees sound"; it is a sophisticated acoustic data analysis system. By capturing minute abnormal noises with a precision 144-channel array and combining deep quantitative analysis of Crest Factor and Kurtosis, Hertzinno is dedicated to making the "heartbeat" of every piece of rotating equipment clearly audible, making unplanned downtime a thing of the past.
