In order to verify the feasibility of the application of wireless sensor network and its architecture in vibration testing of marine cabin electromechanical equipment,this paper improves the existing wireless sensor vibration monitoring nodes by analyzing the advantages of wireless sensor network. A high sampling frequency wireless sensor node and its vibration monitoring system are designed for ship cabin. The sensor system architecture,monitoring node and software design are discussed in combination with the developed wireless sensor network monitoring system. Taking the wired monitoring equipment as the test object,through the field test,the paper compares and studies the wireless sensor monitoring equipment and the wired monitoring equipment in the system structure,data acquisition,and data acquisition. The performance of transmission,data precision and so on,verifies the feasibility of wireless sensor monitoring node in the vibration monitoring of marine cabin electromechanical equipment.
