By monitoring and controlling temperature and stress of concrete in the process of mass concrete casting

temperature crack can be reduced effectively. Aiming at problems of traditional temperature and strain monitoring method

a new kind of distributed temperature and strain wireless monitoring system based on Zig Bee is proposed. Coordinator node and sensor nodes are designed based on Zig Bee protocol

to realize parameters transmission of temperature and strain of concrete. Through GPRS network and Internet

remote data monitoring center receives data packets of temperature and strain of transmitted by coordinator and real-time display acquire parameters by upper PC software programmed by LabVIEW. The experimental result shows that the temperature acquisition value and standard temperature error are within the permitted range（ less than 1 ℃） and the system is stable

reliable

it meets the needs of construction monitoring.
