Description

Technical Field

[0001] The present invention belongs to the technical field of file management, and particularly relates to an intelligent compact shelf obstacle determination device and a determination method. Background Art

[0002] The value of files refers to the usefulness of files to the country, social organizations or individuals. The value of files is a relationship category between the subject (file users and their utilization needs) and the object (files of various types, carriers and contents generated in different eras). Files can only generate or exhibit value when they are related to the needs of the subject. The value of files is not unilaterally determined, but the product of mutual interaction, that is, it depends on the unity of the object attributes of files and the needs of the subject, and neither of them can be missing.

[0003] Files are an important social resource, and their value is mainly reflected in their usefulness to the country, social organizations or individuals. With more and more enterprises and institutions attaching importance to the storage and utilization of files, intelligent compact shelves have been widely used in file warehouses due to their automatic opening and closing functions. The intelligent opening and closing of the shelves improves the utilization efficiency of files, but at the same time, some potential safety hazards have emerged. For example, when a person has not left the aisle of the compact shelf or the file cart and file ladder have not been removed from the aisle of the compact shelf, if the compact shelf closes the shelf body, it will cause personal injury or the compact shelf will tip over or be damaged due to the items not being removed. Similar incidents occur from time to time.

[0004] Therefore, there is an urgent need for a technology to effectively determine whether there are people or obstacles in the aisle of the compact shelf to solve the potential safety hazards in the operation of intelligent compact shelves. Summary of the Invention

[0005] Aiming at the problems raised in the above background art, the purpose of the present invention is to provide an intelligent compact shelf obstacle determination device and a determination method. By deploying this system, it is possible to accurately detect whether there are obstacles in the opened aisle of the compact shelf.

[0006] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0050] A determination method for an obstacle determination device of an intelligent compact rack includes the following steps:

[0051] S1: Set the compact rack control system to collect the working status of the compact rack 110 in real time.

[0052] S2: Turn on the first detection system 105, the second detection system 106, and the third detection system 107 to perform obstacle detection and make obstacle determination.

[0053] S3: If there is an obstacle, the compact rack control system outputs "there is an obstacle"; if there is no obstacle, the compact rack control system outputs "no status".

[0054] S4: When the compact rack control system receives "there is an obstacle", it outputs a switching signal; if there is no obstacle, it continues to operate normally.

[0055] S5: Set an indication system to prompt the staff whether there are obstacles in the compact rack passage. After receiving the switching signal, the indication system issues a voice and light alarm.

[0056] When this solution is installed, the multi-beam transmitter 101 and the multi-beam receiver 102 of the first detection system 105 are respectively installed at a height of 15 cm from the ground, at the entrance and the end of the opening and closing passage of the compact shelves; the multi-beam transmitters 101 and the multi-beam receivers 102 of the second detection system 106 and the third detection system 107 are respectively installed at a height of 100 cm from the ground. By installing the first detection system 105, the second detection system 106 and the third detection system 107, an infrared coverage range without dead angles is formed in the compact shelf passage.

[0057] When in use, for the pre-judgment in the process of sending the switch command of the compact shelves by the compact shelf control system, the system of this solution includes the detection systems, namely the first detection system 105, the second detection system 106 and the third detection system 107, the indication system including voice, lighting and the control system. The indication system uses voice and lighting to remind whether there are obstacles in the compact shelf passage. An opening and closing passage is formed between the moving column 108 and the fixed column 109 of the compact shelves 110. The detection system deploys three groups of infrared light barriers on both sides of the opening and closing passage to determine whether there are obstacles in the compact shelves 110. When the compact shelves 110 are working, the compact shelf control system first obtains whether there are obstacles in the passage through the detection system. If there are obstacles, the compact shelf control system outputs "there are obstacles"; if there are no obstacles, the compact shelf control system outputs "no status". When the compact shelf control system receives "there are obstacles", it outputs a on-off signal; if there are no obstacles, it continues to run normally. After receiving the on-off signal, the indication system issues a voice and lighting alarm.

[0058] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
