PROBLEM TO BE SOLVED: To provide an accident point measurement device using electrical amount data before occurrence of an accident for finding a difference of sampling time between respective terminal devices and performing synchronous correction for easily complying with a multiple terminal system even if no reference signal is taken into the terminal devices. SOLUTION: Each of the terminal devices is provided with a data inputting means, a data storage means, and a data transmission means, while a central processing device is provided with a data acquisition means, a first computing means using the electrical amount data before occurrence of the accident received from the respective terminal devices for calculating a sampling timing difference between the respective terminal devices, a second computing means using the sampling timing difference between the respective terminal devices found by the first computing means for performing synchronous correction, and a third computing means using the electrical amount data of all of the terminals synchronously corrected by the second computing means for performing computing for determining the accident point.
