Method for scheduling meter reading task of electric power collection terminal

Abstract

A method for scheduling a meter reading task of an electric power collection terminal comprises the following steps: S1, respectively creating service containers by taking a meter reading port number of the electric power collection terminal as a unit, realizing a scheduling event list by the service containers through a bidirectional circular linked list, and enabling each node of the scheduling event list to correspond to task scheduling of one port, each port independently manages own tasks; and S2, when a certain port obtains the scheduling opportunity, the service container quotes the operation method of the corresponding service to operate according to the service type. The service container realizes real-time scheduling processing of different ports through access of a double linked list, and realizes parallel execution of the different ports by using least resources; the abstract service enables the meter reading system to be irrelevant to a specific protocol and a user use scene, and the meter reading system starts to execute task scheduling after loading a task; the asynchronous notification is detected through the message queue, so that the real-time task can be preferentially processed.

Description

technical field [0001] The invention relates to a power collection system, in particular to a method for dispatching a meter reading task of a power collection terminal. Background technique [0002] The power collection terminal is a terminal device for power data collection. Its main function is to perform the collection task specified by the user, and collect and store the data corresponding to the task within the specified time. [0003] Due to the complex on-site environment where the collection terminal operates, the types and types of services that need to be executed are complex and diverse. In the implementation of the existing technology, most of the collection terminals can only execute the meter reading in series. When there are multiple meter reading tasks, they can only be executed sequentially according to the priority, which is inefficient; it is helpless and difficult to change different communication protocols. To cope with the needs of users who may be co...

Problems solved by technology

In the implementation of the existing technology, most of the collection terminals can only execute serially when performing meter reading. When there are multiple meter reading tasks, they can only be executed sequentially according to the priority, which is inefficient; it is helpless to change different communication protocols, and it is difficult To meet the needs of users who may be constantly updated
