PURPOSE:To detect the angle of an object on a traveling body in both the traveling and the stop of the body by a method wherein information on an angular velocity is leak-integrated while the body is stopped, it is ordinarily integrated while the body is traveling and the angle of the object is output. CONSTITUTION:A signal processor receives a traveling signal, indicating that a traveling body (a crane) is traveling, from the outside by a traveling-signal detection part 4. An average processing circuit 41 outputs the mean value of angular velocities which are output from a rate sensor 1 while the body is stopped, and it outputs an angular velocity before the start of traveling while the body is traveling. A subtraction processing circuit 31 subtracts a mean value found by the average processing circuit 41 from the angular velocity which is output by the rate sensor 1, and it finds information on an angular velocity. Then, the information, on the angular velocity, which is obtained form the subtraction processing circuit 31 is leak-integrated 5 while the body is stopped, and the information, on the angular velocity, which is obtained from the subtraction processing circuit 31 is ordinarily integrated 10 while the body is traveling. Thereby, the angle of an object is output. |
