| Abstract: | Oxidation- Reduction Potential (ORP) is an important parameter in the process of wastewater treatment. It directly influ- ences the quality and efficiency of the wastewater treating. This paper introduces a new portable ORP measurement instrument based on ARM9 (S3C2410A). The instrument can achieve the function for display, storage and playback of the datum. By using the network of ARM9, the instrument can fulfill network measurement in the distance. It has CAN and RS- 485 interfaces so that it can be used as subordinate system in a normal industrial control system. The software adopts the Multi- sensor data fusion to enhance the mea- surement precision. The system is of high performance- to- price ratio. |
