Embodiment Construction

[0020] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a distributed type task scheduling system. A task middle layer module is used for receiving input task configuration information through an interface and configuring the task configuration information into a dispatching server, and meanwhile stores and provides tasks with task serial numbers for at least two task work nodes. The dispatching server is used for selecting one of the task work nodes according to a stored execution time table for task configuration when the configuration time in the execution time table is due, builds a distributive queue task and sends the task serial number to the selected task work node; the task work node is used for receiving the task serial number sent by the dispatching server, then searching for the stored task number the same as the task serial number sent by the dispatching sever from the task middle layer module, and searching for and executing the corresponding task for execution from the task middle layer module according to the task serial number. The distributed type task scheduling system realizes management on the scheduled tasks in the server, can monitor the execution state of the scheduled tasks in real time and can reasonably handle the corresponding scheduled tasks when the task fails.

Description

technical field [0001] The present application relates to the field of distributed data collection terminals, and more specifically, to a distributed task scheduling system. Background technique [0002] In the prior art, it is usually necessary to execute some planned tasks on a Unix-like server, and the existing solutions basically use the crontab command to execute the tasks periodically. [0003] The current crontab configuration is written separately on the corresponding server. As online services are split into smaller and smaller pieces, the number of service planning tasks and the number of servers to be managed will increase exponentially, and the management of scheduled tasks will change. It is becoming more and more complicated; there is no reasonable monitoring mechanism for the running scheduled tasks; when the server goes down or the power fails, the original tasks cannot be transferred to other servers for completion. [0004] Therefore, how to solve the mana...
