摘要： PROBLEM TO BE SOLVED: To provide a railroad signal system and a railroad signal control method capable of stopping the train when the large external force generating damages or the like on a structure is applied.
SOLUTION: When the external force exceeding a predetermined value is applied to the damage detection place of the railroad structure, a second container in an external force response body 1 is broken, an inclusion body in it leaks and mixes, and electrolyte solution is generated. The red color lamp 62 of a ground signal 61 is turned on to display the stop signal by electrically short-circuiting two rails R1, R2 of the track circuit.

摘要： PROBLEM TO BE SOLVED: To provide a structure residual deformation measuring device having an easy execution method, and capable of measuring a residual deformation of a structure member of the structure, and provide a structure residual deformation measuring method.
SOLUTION: When detecting that an excessive external force exceeding a prescribed discrimination value is applied to the main reinforcing steel 206 of a cast-in-place concrete pile 203, the CPU 45 of a residual deformation measuring part 4 detects elapse of the first one hour after detection of the excessive external force from a timer output, and then closes a changeover switch 54, and performs conduction between an external force response member 1 and a capacitor 51, to thereby accumulate the residual charge in the external force response member 1 into the capacitor 51. Thereafter, the CPU closes a changeover switch 55, allows a voltmeter 52 to measure the voltage of the capacitor 51, operates the residual charge based thereon, and operates the value of the residual deformation based thereon.
