Through the structural and stress analysis of the trestle crane,the key stress-monitoring points affecting safety work are determined,upon the basis of which the general design principles and schemes for the stress-monitoring system based on wireless sensor network technology（WSN） are put forward in the paper.With the IRIS system made by the Crossbow Company as a wireless sensor network platform,the stress-monitoring node circuits and node programs are designed and the software under LABVIEW for the stress monitoring of the trestle crane are developed.The monitoring system may be used to perform real-time stress-monitoring for the structure of the trestle crane,send automatic alarm when the prescribed limits are exceeded,store historical data,process information,etc.
