Dispatching method of annular propulsion timer

Abstract

The invention relates to a dispatching method of a timer, in particular to a dispatching method of an annular propulsion timer which carries out real-time communication protocol conversion, data collection and calculation in a secondary real-time monitoring device of an electric system. According to the requirements of the system, the dispatching method comprises the following steps: collecting an integral number; ensuring and establishing head pointers of W=2<m> timer queues; establishing an annular queue; establishing a global tickcount variable with initialization as 0; and scanning, adding and deleting the timer by the tickcount variable, and the like. The dispatching method uses space to exchange time, greatly increases the scanning efficiency by establishing W+1 global variables and circularly propelling the tickcount simultaneously and can quickly position through the tickcount because a large number of timers are dispersed in the W queues, thereby obviously increasing the adding and deleting efficiency.

Description

technical field [0001] The invention relates to a scheduling method of a timer, in particular to a scheduling method of a timer in which real-time communication protocol conversion, data collection and calculation are carried out circularly in a power system secondary real-time monitoring device. Background technique [0002] In the application of digital substations and digital grids, a large number of secondary side devices and equipment are required. These smart devices need to communicate with other smart devices in this compartment, smart devices in adjacent compartments, and upper and lower smart devices and systems. Exchanges, the protocols of these exchanges may be the same or different; at the same time, smart devices themselves need to perform high-density data collection and computing tasks. The start and completion of these tasks depend on the start, stop, query and other operations of the timer, and the efficiency of these operations of the timer seriously affec...

Problems solved by technology

[0010] The above-described timer scheduling method, when scheduling a large number of timers (such as tens of thousands), usually cannot simultaneously address the following issues: 1, the scanning efficiency of the timer; 2, the deletion and addition efficiency of the timer; 3, the timer 4. Types of timer durations. Currently, digital substations require more and more tasks such as communication, acquisition, and calculation, and the speed is getting faster and faster. There is an urgent need for a general and very efficient scheduling method for massive timers.
