“…The cleanrooms with FFU (Fan Filter Unit) systems have been broadly used in many applications to fulfill the cleanliness requirement during the fabrication process in a variety of high-precision industries [1][2].With the cleanrooms' technology development,the fans and filters can be combined together to form self-powered purification FFU equipment as a cleaner works has been widely used in a variety of purification projects [3]. For the large clean projects, which often use multi-cleanrooms,which have thousands of FFU motors.These need have remote mointoring system with high efficiency to achieve the FFU motors remote mointoring , while the traditional mointoring control existence some defects,such as complex wiring, cabling problems, high cost,control network complexity, poor reliability, anti-interference ability and so on, which is difficult to meet the needs of modern purification projects.…”

In view of the advantage of low voltage power line carrier technique and general packet radio service(GPRS), a solution of fan filter unit(FFU) motor remote mointoring system based on GPRS and low voltage power line communication is introduced. This system combines a framework of low voltage power line communication and GPRS network with host computer monitoring center, which changes the traditional FFU motor control mode, and realize FFU motor remote real-time on-line automatic monitoring.The system implementation methods were described in detail, and the hardware and sofware design were given.The test and practice showed that the proposed has higher efficient and stronger anti-interference capability, which met the requirements of networkization and intelligentization, and a better way for the FFU motor control. The designed system has good application value.
