deterministic scheduling
Vertaling van "deterministic scheduling" in Chinees
定性调度
An objective of an embodiment of the invention is to provide a detection method for industrial Ethernet data monitoring so as to solve the problem that role-equality-based deterministic scheduling in prior art cannot be detected due to communication faults such as data collision and disorder, caused by interferences of industrial fields, in an operational process.
本发明实施例的目的在于提供一种工业以太网数据监控的检测方法，以克服现有技术中基于角色平等的确定性调度由于受到工业现场的干扰而在运行过程中出现数据碰撞和乱序等通信故障而无法检测的问题。
Another objective of the embodiment of the invention is to provide a detection device for industrial Ethernet data monitoring so as to solve the problem that the role-equality-based deterministic scheduling in prior art cannot be detected as it is likely to go wrong.
本发明实施例的另一目的在于提供一种工业以太网数据监控的检测装置，以解决现有技术中基于角色平等的确定性调度容易发生故障而无法检测的问题。
By using the embodiments of the invention, fault detection may be performed on the industrial Ethernet of the role-equality-based deterministic scheduling.
应用本发明实施例可以对基于角色平等的确定性调度的工业以太网进行故障检测。
The industrial Ethernet of the role-equality-based deterministic scheduling is characterized in that real-time data and the non-real-time data are transmitted in different periods of time based on time synchronization of the industrial Ethernet apparatus.
基于角色平等确定性调度的工业以太网的特点在于，以工业以太网设备的时间同步为基础，实时性数据和非实时性数据分时间段进行发送。
The interferences may enable the industrial Ethernet apparatus during running not to execute tasks according to preset processes, thus causing malfunctioning of the role-equality-based deterministic scheduling of the industrial Ethernet easily.
这些干扰可能会使工业以太网设备在运行中出现不按照预先设定的流程执行任务的现象，这就容易造成工业以太网的基于角色平等的确定性调度发生故障。
Because there are defects in hardware and software of the industrial Ethernet apparatus, it is possible to result in malfunctioning of the role-equality-based deterministic scheduling of the industrial Ethernet.
由于工业以太网设备的硬件和软件设计之间存在缺陷，也容易引起工业以太网的基于角色平等的确定性调度存在发生故障的可能性。
The existing industrial Ethernet is role-equality-based deterministic scheduling.
现有的工业以太网是基于角色平等的确定性调度。
p, li {white-space: pre-wrap;} Batch Scheduling (Since Linux 2.6.16.) This policy is similar to Normal, except that this policy will cause the scheduler to always assume that the process is CPU-intensive. Consequently, the scheduler will apply a small scheduling penalty so that this process is mildly disfavored in scheduling decisions. This policy is useful for workloads that are non-interactive, but do not want to lower their nice value, and for workloads that want a deterministic scheduling policy without interactivity causing extra preemptions (between the workload's tasks).
p， li ｛white- space： pre- wrap；｝ 批处理调度 （自 Linux 2. 6. 16 以后） 和 普通 调度规则近似， 区别在于这种规则会假设进程都是 CPU 密集型的。 因此在这种方案下， 相应进程会在调度中受到一定的 CPU 等待时间惩罚， 但优先级不会低于 nice 设定值。 如果您需要一种固定的调度顺序， 并且不希望因交互式规则导致其它进程额外抢占过多的 CPU 时间， 这种规则会很有用 。
