Early detection and notification system for collapse / collapse

摘要

To provide a land collapse / collapse early detection notification system useful for evacuation and safety measures.A detection notification system body and a fixing pile are constituted. The detection and reporting system main body includes a housing BX, a detection sensor unit S, a calculation control unit C, a power supply unit BS, and a transmitting / receiving antenna A, and includes a detection sensor unit S, a calculation control unit C, a power supply unit BS, Is housed in the housing BX and the detection sensor section S, the calculation control section C, and the power supply apparatus BS are electrically connected to each other, and the acceleration due to the collapse / collapse and / or the left and right inclination , The information of the measured acceleration VA (i) and the measured inclination VI (j) is transmitted to the calculation control unit C by the detection sensor unit S, and the calculation control unit C transmits the measured acceleration VA (i ), And when the measured inclination VI (j) becomes equal to or larger than the acceleration threshold CA (i) and the inclination threshold CI (j) set in advance, the time tc at that time is measured. Here, i = 1 to 3, j = 1 to 2.(FIG.
