1) A first mode of operation (object finding mode).
The article searching device 20 enters a first working mode after receiving the first selection instruction, and in the first working mode, the processor 22 is configured to generate a first adjustment instruction after receiving the query instruction, and send the first adjustment instruction to the reader/writer 21, so that the reader/writer 21 adjusts the power of the reader/writer 21 to a first preset power, that is, in an initial state of the first working mode, the reader/writer 21 performs a large-scale search with a higher power; then, when the distance between the object-searching device 20 and the target object is less than or equal to the preset distance, a second adjustment instruction is generated, and the second adjustment instruction is sent to the reader/writer 21, so that the reader/writer 21 adjusts the power of the reader/writer 21 to a second preset power, and the object within the preset range is scanned, so as to find the target object from the objects within the preset range, wherein the preset range is a range in which the distance between the preset range and the end point position is less than the preset distance.
For example: when a user wants to search the "near-current surrogates of china" in a library, a first selection instruction is input into the article-searching device 20, the article-searching device 20 is set to a first working mode, meanwhile, an inquiry instruction for searching the "near-current surrogates of china" is input into the article-searching device 20, in the first working mode, the processor 22 generates a first adjustment instruction after receiving the inquiry instruction, so that the power of the reader/writer 21 is adjusted to a first preset power (i.e. high power), and then the reader/writer performs remote communication with a second electronic tag in the library to obtain the current position information of the article-searching device 20, and then the user is guided to the position where the "near-current surrogates of china", i.e. the bookshelf corresponding to the "near-current surrogates of china", by combining with the navigation information and the current running direction, when the user reaches the corresponding bookshelf, i.e. when the distance between the article-searching device 20 and the target object is less than the preset distance, a second adjustment instruction is generated to adjust the power of the reader/writer 21 to a second preset power (i.e., low power), and then the reader/writer performs close-range communication (e.g., 0.1 meter) with the first electronic tag of the book, and scans the book within a preset range (i.e., the range of the bookshelf), thereby finding the "recent passage history of china" in the bookshelf.
2) A second mode of operation (management mode).
The article searching device 20 may enter a second working mode after receiving the second selection instruction, and in the second working mode, the processor 22 is configured to generate a third adjustment instruction and send the third adjustment instruction to the reader/writer 21, so that the reader/writer 21 adjusts the power of the reader/writer 21 to the first preset power, that is, in an initial state of the second working mode, the reader/writer 21 performs large-scale scanning with a higher power; the article searching device 20 is further configured to scan the first electronic tag to obtain the first identification data sent by the first electronic tag, so as to detect whether the object in the preset object library is lost based on the first identification data.
For example: when a library administrator manages books in a library, a second selection instruction can be input into the article searching device 20, a management password is input into the article searching device 20, the article searching device 20 is adjusted to be in a second working mode, the reader-writer 21 is automatically adjusted to be at a first preset power (namely high power), the administrator can use the article searching device 20 to scan each bookshelf at a long distance (for example, 2 meters), so as to directly acquire first identification data sent by first electronic tags on all books on the bookshelf, the information of all books on the bookshelf can be summarized by remotely scanning in front of each bookshelf for 3 seconds, then the acquired first identification data corresponding to the first electronic tags of all books are compared with a book database prestored in the article searching device 20, so that whether the books are lost or not can be detected in time, and the lost book can be specifically acquired at the same time, the management of the books in the library is more convenient and effective, and the counting time of managers is greatly saved.
It is understood that, in other embodiments, the article searching device 20 in the second operating mode may also plan a navigation route for the administrator to optimize the scanning path of the administrator, and at the same time, when there are many shelves, the administrator is prevented from missing shelves, thereby improving the management efficiency.
3) A third mode of operation (browsing mode).
The article searching device 20 can generate a recommendation table according to the number of times that the article in the preset range is searched, and when the distance between the article searching device 20 and the first electronic tag is smaller than the preset distance, the recommendation table is displayed and comprises related information of at least one article; it can be understood that the article searching device 20 may enter the third operating mode after receiving the third selection instruction, and may also automatically enter the third operating mode when the user does not input any selection instruction, and in the third operating mode, the processor 22 generates the fourth adjustment instruction, sends the fourth adjustment instruction to the reader/writer 21, and adjusts the power of the reader/writer 21 to the first preset power (i.e., high power), thereby implementing the remote communication with the electronic tag.
