A front‐end control system for composite insulators'image on‐line acquisition based on wireless communication was designed to improve the safety of the on‐line hydrophobicity detec‐tion of composite insulators .The system consisted of water spraying device ,image acquisition device ,wireless transceiver and computer , the water spraying device communicated with the wireless transceiver inserted in the computer through the 2 .4G wireless module and the image ac‐quisition device communicated with the computer through WiFi .When the water spraying device and the image acquisition device were installed on the top of the transmission tower ,they could be controlled to spray water and take a picture to store in the computer .Then the picture could be used to analyze the level of hydrophobicity of the composite insulators by the hydrophobicity a‐nalysis software .Test results showed that the system worked not only stably but also safely and had the capability of strong anti‐jamming .The package loss rate of wireless communication was less than 3 .5% .Besides ,when the battery was charged once ,the system could work continuous‐ly for 14 h .The image acquired is clear which is suitable for detecting the hydrophobicity of com‐posite insulators .
