In the aviation information filing method of the present invention, the focus arrangement section manages the presence or absence of filing for each content of a plurality of aviation information as a bitmap, and the key section registers the serial number of the plurality of aviation information as a key. The section registers a plurality of pieces of aviation information by content, and the aviation information updating means registers the serial number of the aviation information as a key in the key section when registering the aviation information, stores the aviation information itself in the data section, and adjusts the focus alignment. The bit position corresponding to the serial number of the relevant aviation information and the content of the relevant aviation information in the part is turned on, and the aviation information extraction means extracts the logical operation result of the row corresponding to the content to be extracted in the bit array part when extracting the aviation information. Based on the key part, the serial number of the corresponding aviation information is obtained, and the aviation information is extracted from the data part according to this serial number.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an aviation information filing system according to an embodiment of the present invention. The aviation information filing method of this embodiment includes: a bit array section 1 that manages the presence or absence of filing for each content of a plurality of aviation information as a bitmap; a key section 2 that registers a serial number of a plurality of aviation information as a key; a data section 3 for registering a plurality of pieces of aviation information by content; an aviation information updating means 4 for registering, adding, changing, and deleting aviation information; and an aviation information extraction means 5 for extracting aviation information in response to an extraction request. It is composed of:

As shown in FIG. 2, for example, the content of aviation information (for example, airport, airspace) registered in the data section 3.

It is assumed that there are a maximum of m (positive integer) types of radio stations, runways, etc., and the maximum number of aeronautical information registered in the data section 3 is nnn.
Assuming that there are n (n is a positive integer) bit array part l is secured as a two-dimensional array with m rows and nnnn columns. Each row of the bit array section 1 corresponds to each content of aviation information, and each column corresponds to a serial number of the aviation information. Note that in the initial state of the bit array unit 1, all bit positions are initialized to off (0), which indicates that no aviation information is registered. Further, the key section 2 is secured as a one-dimensional array having nnnn entries.

Next, the operation of the aviation information filing system of this embodiment configured as described above will be explained.

First, when registering aviation information, the aviation information updating means 4:
The serial number of the aviation information is registered as a key in the key section 2, and the aviation information itself is stored in the data section 3 according to its contents,
The bit position in the column corresponding to the serial number of the aviation information in the row corresponding to the content of the aviation information in the bit array section 1 is turned on (1).

If there are multiple contents of the aviation information to be registered, turn on (1) the bit position of the column corresponding to the serial number of the aviation information in the multiple rows corresponding to the contents of the aviation information in the bit array section 1. do.

Furthermore, in the case of adding aviation information (adding new content to already registered aviation information), the aviation information updating means 4 not only stores aviation information by content in the data section 3; , the bit position in the column corresponding to the serial number of the aviation information in the row corresponding to the content of the aviation information in the bit array section 1 is turned on (1).

Furthermore, in the case of changing the aviation information (changing the contents of already registered aviation information), the aviation information updating means 4 only changes the contents of the aviation information to the data section 3.

Furthermore, the aviation information updating means 4 deletes aviation information (
In the case of deleting part or all of the content of already registered aviation information), not only do you delete each content of aviation information from the data section 3 (this does not actually have to be done), but also delete the key section. Delete the serial number of the relevant aviation information from 2 (this is not done in the case of deleting part of the contents of the already registered aviation information), and delete the serial number of the relevant aviation information from The bit position in the column corresponding to the serial number of the aviation information is set to off (0).

On the other hand, when extracting aviation information, the aviation information extraction means 5:
Perform logical operations (logical product, logical sum, etc.) on the rows of bit array part 1 corresponding to the content specified by the complex content extraction request, and select the column whose result is on (1) as the key part. 2 is converted into a serial number, and the corresponding aviation report is extracted from the data section 3 according to this serial number. The valid (registered) content of the extracted aviation information is determined by whether the bit information in the column corresponding to the serial number of the aviation information in bit array section 1 is on (1) or off (0). This can be determined by checking whether

As described above, according to the aviation information filing method of this embodiment, the bit array part is set up as a bitmap in which the rows correspond to the contents of the aviation information and the columns correspond to the serial numbers of the aviation information, and the aviation information is registered. By turning on the corresponding bit position, all aircraft to be extracted can be retrieved by simply performing a simple logical operation on the row corresponding to each content in the bit array section in response to a complex content extraction request. The serial number of information can be easily obtained.

〔Effect of the invention〕

As explained above, the present invention manages the serial number of aviation information and the presence/absence of filing of aviation information for each aviation information content as a bit map in the bit array section. The serial number of the aviation information to be extracted can be easily obtained by the logical operation of the row corresponding to the row, which has the effect of simplifying the aviation information extraction process and significantly shortening the aviation information search time.
