Aiming at the demerit of current intelligent sensor network with large size,high power and low quality,an embed-ded network smart sensor system with the upper computer in the on-chip ROM integration CANopen LPC11C24 low power microprocessor of the drive and QT is designed with the characteristic of small size,low power.The sensor network with CANopen standard-based offers multiple API interface and integrates LPC11C24 into the embedded network application. Based on the QT design PC interface can complete the CAN bus network management and configuration of multiple point sensor.The testing results show that the sensor network accomplishes the design goal of small size,low power,cost-effec-tive principle,expandability and speeds up the development and application of intelligent sensor.
