Problems solved by technology

[0002] The demand for graphic information broadcasting is very large, and the demand is varied. For each individual demand, it is necessary to program and write codes to achieve specific functions. The workload is heavy, and the program is not easy to modify and maintain.
[0003] The current method of controlling tasks is only start and stop, and tasks can only be controlled, and tasks cannot control each other
In the process of automatically broadcasting information in this way, some needs cannot be met

example 1

[0036] like image 3 As shown, a variety of different information are broadcast on one screen at the same time. In area 1, the K-line chart of each stock in the Shanghai stock market is flipped and broadcast, and in area 2, the K-line chart of each stock in the Shenzhen stock market is flipped. It is required that the content in area 1 and area 2 be scrolled at the same time. In order to achieve the above requirements, the following three tasks are required:

[0037] Task 1 (Shanghai stock market): Responsible for the broadcast of all Shanghai stock K-line charts, set to not automatically turn the screen;

[0038] Task 2 (Shenzhen): Responsible for the broadcasting of all Shenzhen stock K-line charts, set to not automatically scroll;

[0039] Task 3 (script): responsible for controlling when the first two tasks start broadcasting, when they stop broadcasting, and when they turn the screen.

[0040] For task 1 and task 2, make the following settings: When the command is re...

example 2

[0045] exist image 3 Area five of the shown screen broadcasts the stock prices of the Shanghai stock market and the Shenzhen stock market. It is required to turn the screen to broadcast all Shanghai stock prices first, then broadcast all Shenzhen stock prices, and then broadcast all Shanghai stock prices again, and so on.

[0046] In order to achieve the above requirements, the following three tasks are required:

[0047] Task 1 (Shanghai Stock Market), Task 2 (Shenzhen Stock Market): Set it to automatically turn the screen every 2000 seconds, and set it to automatically stop after playing all the data once, and send a command to the script task. Task 3 (script) is set as Figure 5 shown.

[0048] The workflow of the playbook is as follows:

[0049] Start , then suspend execution until triggered;

[0050] was set to stop automatically, after the broadcast was over, it stopped automatically and sent a command to the script;

[0051] After the script re...

Abstract

The invention relates to a method and a system for intercommunication between tasks. A source task transmits remote control commands to a remote control command receiver via a transmitting module, the remote control commands comprises target task names and task executing manners which include initiating, stopping and triggering. The remote control command receiver transmits the remote control commands to a task manager in a pushing manner. The task manager transmits the remote control commands to a target task according to the target task names in the remote control commands, the target task receives the remote control commands via a receiving module, executes the remote control commands according to the task executing manners, and returns the executing results to the source task. By the aid of the method for intercommunication between the tasks, the intercommunication between the tasks is realized according to the remote control commands.

Description

technical field [0001] The invention relates to a method and system for mutual communication between tasks, which is suitable for occasions such as television stations, airports, stock exchanges and the like that require automatic broadcasting of information. Background technique [0002] The demand for graphic information broadcasting is very large, and the demand is varied. For each individual demand, it is necessary to program and write codes to realize specific functions. The workload is heavy, and the program is not easy to modify and maintain. [0003] At present, the only way to control tasks is to start and stop, and tasks can only be controlled, and tasks cannot control each other. In the process of automatically broadcasting information in this way, some requirements cannot be met. For example, precise control over the simultaneous operation of two tasks. If tasks are allowed to communicate with each other, functions such as synchronous operation of two tasks can...
