CONSTITUTION:Abnormality detecting action is normally performed in PID control part 20 based on a microcomputer. When an abnormality occurs in any of the central processing unit 29, temporary memory 32, fixed memory 31 and convertors 33, 34 and normal steering is hindered, a watch dog timer 35 promptly interrupts conduction to a relay coil to switch each central point of contact 39a, 40a of relay switches 39, 40. Accordingly, output signal voltage to a rudder driving part 21 comes to OV, and said part 21 sets a rudder 25 in the central direction and puts the hull in a straight sailing condition. On the other hand, an annunciator 43 not only blows a buzzer 41 but also lights a lamp 42 to give an alarm for the abnormality.,下面是Automatic steering gear专利的具体信息内容。
