Embodiment 1

[0048] A specific embodiment of the present invention discloses a unified scheduling method for hardware resources in a control system, such as figure 1 shown, including the following steps:

[0049] S1. Establish a communication link between the business logic layer and the hardware resource management layer in the control system, and store all topic subscription information initiated by the business logic layer;

[0050] S2. The hardware resource management layer waits in a loop to receive the message sent by the business logic layer. After receiving the message, it analyzes the content of the message, determines the control type, and performs corresponding communication, AD or IO operations according to the control type. ;

[0051] S3. The hardware resource management layer waits in a loop to receive the data generated by the hardware resource port. When the data is received, data matching is performed according to the stored topic subscription information according to the...

Embodiment 2

[0056] To improve on the basis of Example 1, the step S1 further includes the following steps:

[0057] S11. Establish a business logic layer and a hardware resource management layer in the control system;

[0058] S12. The hardware resource management layer receives the registration application initiated by the business logic layer, and establishes a Socket communication link with the business logic layer; specifically, after the resource management layer receives the registration application, it obtains the information in the registration application Store the name of the device where the business logic layer is located and the local Socket, and establish a Socket communication link between the business logic layer and the resource management layer;

[0059] S13. Through the Socket communication link, the hardware resource management layer receives and stores all topic subscription information initiated by the business logic layer.

[0060] Preferably, step S1 further inclu...

Abstract

The invention, which belongs to the technical field of hardware resource scheduling, relates to a unified scheduling method of hardware resources in a control system, thereby problems that much attention needs to be paid to the hardware resource management, the designed system is complicated, the maintenance and upgrading can not be realized conveniently and communication information filtering cannot be realized. The method comprises: establishing a communication link between a service logic layer and a hardware resource management layer in a control system and storing all topic subscriptioninformation initiated by the service logic layer; cyclically waiting for receiving of messages sent by the service logic layer by the hardware resource management layer, parsing the message contents after message receiving, determining control types, and performing corresponding communication, AD or IO operation according to the control types; and cyclically waiting for receiving of data generatedby a hardware resource port by the hardware resource management layer, carrying out data matching based on the stored topic subscription information according to a preset subscription mode, and packaging the data and then sending the data packet to the corresponding service logic layer under the condition of consistent matching.

Description

technical field [0001] The invention relates to the technical field of hardware resource scheduling, in particular to a method for unified scheduling of hardware resources in a control system. Background technique [0002] In the control system, information interaction of hardware resources is essential. At present, there are many kinds of hardware resources, and each hardware resource has an independent management interface. Existing control systems independently operate hardware resources according to business logic requirements, and process various communication information separately. Under this kind of control system, business logic and hardware management are intertwined. The two do not have a unified interface, and they cannot selectively receive and process communication information. Therefore, it is necessary to pay too much attention to the management of hardware resources in the design of the control system. The system is relatively complex, not easy to maintain ...
