摘要
A method and apparatus for wireless measurement of the temperature in curing concrete is characterized by the use of a plurality of surface acoustic wave temperature sensors embedded in the concrete. An interrogation signal from an external transceiver system is modified by the sensors in accordance with the temperature of the concrete adjacent to the sensors. The return signals from the sensors are processed in a correlation device to identify each signal as originating from a specific sensor. A microprocessor calculates the maturity of the concrete based on the data received from the sensors as well as data input corresponding to the type of concrete. The maturity data is used to analyze the strength and integrity of the concrete structure being built.
