PURPOSE:To detect the angle of a bank and generate a warning when there is the possiblity of fall down by providing an acceleration sensor consisting of the 1st sliding resistor and the 2nd sliding resistor, an analog digital converter, etc. CONSTITUTION:The acceleration sensor 5 consists of the 1st sliding resistor 51 which consists of a sliding contact 51d and a sliding resistance 51c while supported pivotally on a support shaft 51a and the 2nd sliding resistor 53 which consists of a sliding resistance 53b and a sliding contact 53a freely oscillating in the axial direction of said support shaft 51a by a weight 54 and a spring 52. Then, the values of the 1st sliding resistor 51 and the 2nd sliding resistor 53 are converted into digital signals by the analog-digital converter of the 1st interface 7a. Those digital signals are inputted to the input port of a CPU8 to calculate the angle theta (degree) of the bank, generating a warning when there is the possibility of falling down. |
