Abstract
An apparatus includes an acquisition means for acquiring the displacement quantity in a time-series manner, the displacement quantity being generated at a measurement part of a structure by the weight of a vehicle that travels on the structure, a detection means for detecting the position and the clock time of the vehicle that travels a pre-passage area of the measurement part, an estimation means for estimating the arrival time that the vehicle arrives at the measurement part, from the position of the measurement part and the position and the clock time of the vehicle, and a control means for controlling the acquisition means on the basis of the estimated arrival time.
Claims14
A displacement measurement apparatus for a structure, the apparatus comprising:
- a memory containing program instructions;
- and
- a processor coupled to the memory, wherein the processor is configured to execute the program instructions to:
- acquire displacement quantity in a time-series manner, the displacement quantity being generated at a measurement part of the structure by weight of a vehicle that travels on the structure;
- detect a position and clock time of the vehicle that travels a pre-passage area of the measurement part;
- estimate arrival time that the vehicle arrives at the measurement part, from a position of the measurement part and the position and the clock time of the vehicle;
- and
- control the acquisition on a basis of the estimated arrival time.
A displacement measurement method for a structure, the method comprising:
- acquiring displacement quantity in a time-series manner, the displacement quantity being generated at a measurement part of the structure by weight of a vehicle that travels on the structure;
- detecting a position and clock time of the vehicle that travels a pre-passage area of the measurement part;
- estimating arrival time that the vehicle arrives at the measurement part, from a position of the measurement part and the position and the clock time of the vehicle;
- and
- controlling the acquiring on a basis of the estimated arrival time.
A non-transitory computer-readable storage medium storing therein a program comprising instructions for causing a computer to perform processing of:
- acquiring displacement quantity in a time-series manner, the displacement quantity being generated at a measurement part of the structure by weight of a vehicle that travels on the structure;
- detecting a position and clock time of the vehicle that travels a pre-passage area of the measurement part;
- estimating arrival time that the vehicle arrives at the measurement part, from a position of the measurement part and the position and the clock time of the vehicle;
- and controlling the acquiring on a basis of the estimated arrival time.
