METHODS AND SYSTEMS FOR PREVENTING UNSAFE OPERATIONS

摘要

A system for preventing an unsafe operation of at least one machine communicatively coupled to a computing device. The system includes the computing device which includes a processor coupled to a memory. The memory contains processor-executable instructions that, when executed, cause the computing device to perform the steps of storing, in the memory, a first state of a first machine of the at least one machine, generating a first pending output to be issued to the first machine, determining whether an unsafe condition would result if the first pending output is issued to the first machine in the first state, and issuing the first pending output upon determining that issuing the first pending output would not result in an unsafe condition and blocking the first pending output from being issued upon determining that issuing the first pending output would result in an unsafe condition.

1. A system for preventing an unsafe operation of at least one machine communicatively coupled to a computing device, the system comprising said computing device, said computing device including a processor coupled to a memory, said memory containing processor-executable instructions that, when executed by said processor, cause said computing device to perform the steps of:
storing, in said memory, a first state of a first machine of the at least one machine; generating a first pending output to be issued to the first machine; determining whether an unsafe condition would result if the first pending output is issued to the first machine in the first state; and issuing the first pending output upon determining that issuing the first pending output would not result in an unsafe condition and blocking the first pending output from being issued upon determining that issuing the first pending output would result in an unsafe condition.
