Abstract
Abstract An automatic operation recovery system for automatically removing an operational failure caused in an apparatus whose complete operation is controlled by actuators operated in a predetermined sequence, thereby recovering the apparatus to its normal operating condition, comprises an actuator driver for controllably driving the actuators in a sequence suitable for a type of operational failure so as to remove the operational failure, a memory for accumulatively storing data of a type of operational failure and a sequence taken to remove the type of operational failure through the actuator driver and an automatic recovery controller for, when an operational failure is detected, assigning an order of priority to sequences available for removing the same type of operational failure accumulatively stored in the memory and automatically actuating the actuator driver to operate the actuators in a sequence assigned the first order of priority.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
237 words
An automatic normal operation recovery system used in cooperation with a sequentially controlled apparatus having a plurality of actuators which are operated in a predetermined sequence to perform a sequential operation of said sequentially controlled apparatus for automatically removing an operational failure caused in said sequentially controlled apparatus by actuating said actuators, thereby recovering said sequentially controlled apparatus to its normal operating condition, said recovery system comprising; operational failure detecting means for detecting an occurrence and a type of an operational failure caused in said sequentially controlled apparatus; actuator operating means for operating said actuators in a sequence suitable for a type of operational failure detected by said operational failure detecting means so as to remove said type of operational failure, thereby recovering said sequentially controlled apparatus to its normal operating condition; memory means for accumulatively storing data of a type of operational failure detected by said operational failure detecting means and a sequence taken to remove said type of operational failure through said manual recovery means; and automatic recovery means for, when an operational failure is detected by said operational failure detecting means, assigning an order of priority to all sequences available for removing the same type of operational failure as said operational failure detected by said operational failure detecting means accumulatively stored in said memory and automatically actuating said actuator operating means to operate said actuators in a sequence assigned the first order of priority.
Claim 2
Dependent Claim

An automatic normal operation recovery system used in cooperation with a sequentially controlled apparatus having a plurality of actuators which are operated in a predetermined sequence to perform a sequential operation of said sequentially controlled apparatus for automatically removing an operational failure caused in said sequentially controlled apparatus by actuating said actuators, thereby recovering said sequentially controlled apparatus to its normal operating condition, said recovery system comprising; operational failure detecting means for detecting an occurrence and a type of an operational failure caused in said sequentially controlled apparatus; actuator operating means for operating said actuators in a sequence suitable for a type of operational failure detected by said operational failure detecting means so as to remove said type of operational failure, thereby recovering said sequentially controlled apparatus to its normal operating condition; memory means for accumulatively storing data of a type of operational failure detected by said operational failure detecting means and a sequence taken to remove said type of operational failure through said manual recovery means; and automatic recovery means for, when an operational failure is detected by said operational failure detecting means, assigning an order of priority to all sequences available for removing the same type of operational failure as said operational failure detected by said operational failure detecting means accumulatively stored in said memory and automatically actuating said actuator operating means to operate said actuators in a sequence assigned the first order of priority.
Claim 3
Dependent Claim
28 words
An automatic normal operation recovery system as defined in claim 1, wherein said actuator operating means is changed between a manual operating mode and an automatic operating mode.
Claim 4
Dependent Claim
58 words
An automatic normal operation recovery system as defined in claim 2, wherein said memory means accumlatively stores data of a sequence manually taken when said actuator operating means is in said manual operating mode, or automatically taken when said actuator operating means is in said manual operating mode, to rermove an operational failure through said manual recovery means.
Claim 5
Dependent Claim
37 words
An automatic normal operation recovery system as defined in claim 3, wherein said automatic recovery means repeats a predetermined number of times said automatic actuation of said actuator operating means unless an operational failure is not removed.

Claim 7
Dependent Claim
110 words
An automatic normal operation recovery system as defined in claim 1, wherein said automatic recovery means assigns each said sequence an order of priority based on at least one of parameters of a probability of recovery P which is a ratio of the number of successful removals of a same type of operational failure by each said sequence relative to the total number of trials of each said sequence for said same type of operational failure, a recovery time T which is a period of time needed to successfully remove said same type of operational failure by each said sequence, and the number of operations N for actuating said actuators.
Claim 8
Dependent Claim
93 words
