Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a data queue management system in an information transmission device.

(Prior Art) In data transmission, it is important to increase the efficiency of data transmission without increasing the size of the device. For example, in the field of information transmission, when a telemeter slave station that relays data to a grandchild station relays data to a master station, it is necessary to efficiently and appropriately relay and transmit its own station's data and grandchild station data in the order of reception. be.

FIG. 3 is an explanatory diagram of a conventional data queue management system.

First, in FIG. 3a, there is only one queue management area, and the data is managed by unifying the format to the one with the largest amount of information. That is,
In Figure 3a, information A is also information B, which has a large amount of information.
Data was managed in a unified format.

In FIG. 3b, each piece of information has its own queue management area and is managed individually. That is, information A is queue A management area 2-
1. Information B has a queue management area 2-2 and a separate queue management area for each piece of information.

(Problem to be Solved by the Invention) However, in the data queue management method shown in FIG. In some cases, there was a problem in that the management area became vacant and wasted, resulting in the management area becoming larger.

Further, in the data queue management method shown in FIG. 3B, each data has its own separate management area, so there is a problem in that the order in which information of different types is generated becomes unclear.

SUMMARY OF THE INVENTION The present invention aims to eliminate the above-mentioned problems, clarify the order of generated information, eliminate waste of management area, and provide a different type of queue management method that enables appropriate information transmission. do.

(Means for Solving the Problems) In order to solve the above problems, the present invention, in a queue management system of different types, attaches an identification code to each type of data of different types, and uses the identification code. A primary queue management area that stores the data in the order of occurrence and a plurality of secondary queue management areas that store the contents of the data for each model are provided, and when each data is input, the data is stored in the order of occurrence. An identification code is created and stored in the primary queue management area, and data contents are stored in the secondary queue management area according to the type expressed in the identification code, and when the data is processed, the data is stored in the primary queue management area. The identification code is retrieved from the primary queue management area in accordance with the order of reception in the queue management area, and the content of the required data is retrieved from the secondary queue management area corresponding to the identification code and data processing is performed. This is what I did.

(Function) According to the present invention, as shown in FIG. 1, in a queue management system of different types, identification codes are attached to each type of data of different types, and the identification codes are stored in the order of occurrence. A next queue management area 11 and a plurality of secondary queue management areas 12 for storing the contents of the data for each type are provided. Therefore, when the data is input, an identification code is created from the data according to the order of occurrence,
While storing it in the primary queue management area 11,
The content of the data is stored in the secondary queue management area 12 according to the type expressed in the identification code, and the data is stored in the primary queue management area 11 according to the order received in the primary queue management area at the time of processing the data. The identification code is extracted from the identification code, and the required data contents are extracted from the secondary queue management area 12 according to the identification code and data processing is performed. Therefore,
Data files can be stored in the primary queue management area 11 in the order in which the data is generated, so that the order in which the pieces of information are generated does not become unclear. Furthermore, since the data is stored for each type in the plurality of secondary queue management areas 12, no management area is wasted.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of different types of queue management systems showing one embodiment of the present invention.

As shown in this figure, in the present invention,
Identification codes are assigned to various data of different types to be transmitted, and a primary queue management area (primary buffer) 11 is provided to store the identification codes in the order in which they occur, thereby ordering the data. Furthermore, a plurality of secondary queue management areas (secondary buffers) 12 are provided which are determined by the contents of the data. In other words, the secondary queue management area 12 is provided with a plurality of queue management areas a, b, . . . for each type.

FIG. 2 is a flowchart of different types of queue management of the present invention.

The operation of different types of queue management according to the present invention will now be described.

(1) Data is generated (step).

That is, as shown in FIG. 1, a plurality of pieces of information a, information b, . . . , information n of different types are generated asynchronously.

(2) Add an identification code to the data to display the model number (step). An identification code indicating this type is assigned depending on the location where the data is generated.

(3) Identification codes are set in the primary queue area 11 in the order of data generation, and data contents are set for each type in a plurality of secondary queue areas 12 of different types (step).

That is, as shown in FIG. 1, identification codes representing each model are set in the primary queue management area 11 in the order of occurrence, and each of information a, information b, ..., information n is Dedicated (for each model) 2
The data contents are set in the next queue management air 12.

(4) Take out the identification code from the primary queue area 11 (step).

(5) Retrieve the contents of the required data corresponding to the identification code from the secondary queue area 12 (step) and process the data.

Note that step and step indicate the taking of data into the queue, and step and step indicate the taking out of data from the queue.

By providing the primary queue management area 11 in this way, the order of occurrence of the generated information becomes unclear, unlike in the conventional data queue management system shown in FIG. 3b. There is no
Able to perform appropriate data processing. Also, 2
By providing the next queue management area 12, it is possible to eliminate the problem of wasting the management area as in the conventional data queue management system shown in FIG. 3a.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

(Effects of the Invention) As described above in detail, according to the present invention,
A primary queue management area for ordering data and a plurality of secondary queue management areas for storing the contents of the data are provided, and various types of data with different formats are assigned identification codes to display their respective formats. The identification codes are stored in the primary queue management area in the order of occurrence, and the contents of the data are stored in the secondary queue management area according to the model expressed by the identification code, and the data is processed. At that point, the identification code is retrieved from the primary queue management area in accordance with the order of reception in the primary queue management area, and the required data is retrieved from the secondary queue management area according to the identification code. Enable data processing. In other words, by providing a primary queue management area for overall management, data files can be stored in the primary queue management area in the order in which they occur, and the order in which information is generated is not unclear. . Moreover, by providing a dedicated secondary queue management area for each data type, no management area is wasted.

Therefore, for example, in the field of information transmission, when a telemeter slave station that relays data from a grandchild station relays data to a master station, it is possible to efficiently and appropriately relay the own station's data and the data from the grandchild station in the order of reception. can be transmitted.
