Zhuang, L., 2019. Design of vibration signal data acquisition system for ship mechanical and electrical equipment. In: Hoang, A.T. and Aqeel Ashraf, M. (eds.), Research, Monitoring, and Engineering of Coastal, Port, and Marine Systems. Journal of Coastal Research, Special Issue No. 97, pp. 254–260.The acquisition and transmission of vibration signal data of ship electromechanical equipment is affected by the multi-path interference factors, which leads to the limited bandwidth of data acquisition and the poor continuous readout performance of data. In order to improve the stability of ship electromechanical equipment operating conditions, a design method of ship electromechanical equipment vibration signal data acquisition system based on wireless sensor network is proposed. The sensor distributed array design of remote data monitoring for ship electromechanical equipment is carried out by using wireless sensor network information acquisition technology, and the vibration signal data of ship electromechanical equipment collected by sensors are quantitatively integrated and processed. The vibration signal data acquisition of ship electromechanical equipment is carried out by using vibration sensor, the interface of vibration signal data acquisition channel of ship electromechanical equipment is designed with PCI global bus control technology, the human-computer interactive control of data acquisition is carried out by using SCSI bus controller, and the hardware integration design of vibration signal data acquisition system of ship electromechanical equipment is carried out. The test results show that the system can collect multi-channel monitoring data in real time and accurately, the fidelity of data output is high, the balance of acquisition and output channel is good, and the accurate detection and analysis ability of vibration signal data of ship electromechanical equipment is improved.
