DETAILED DESCRIPTION
[0024] The present application is further described in conjunction with the following embodiments, but those skilled in the art will understand that the following examples are only used to illustrate the present application, and should not be regarded as limiting the scope of the present application. The specific conditions are not specified in the examples, and are carried out according to the conventional conditions or the conditions recommended by the manufacturer. The reagents or instruments used are not specified by the manufacturer, and are conventional products that can be obtained by commercial purchase; the specific embodiments described are only used to explain the principles of the present application, and are not used to limit the present application.
[0025] In order to overcome the pain points of unknown state, difficult positioning, missing operation record, weak safety management and the like in traditional mechanical room management, the embodiment provides a mechanical room railway relay intelligent inventory management system, which at least comprises Figure 1 、 2 The relay intelligent storage cabinet system comprises: a layer plate 1 of a storage cabinet for storing objects, a first UHF RFID reader 3 for sensing and reading a first RFID tag 2 on the stored object is fixed on the layer plate 1; at least one UHF RFID antenna is fixed on the layer plate 1 and covers the first RFID tag 2, so as to sense and read all relays attached with the first RFID tag 2 entering the sensing area thereof, and realize recording and storing of the relays. And a first RFID data acquisition module 4 fixed on the storage cabinet is used to receive the first RFID transmission signal of the first UHF RFID reader 3 and transmit it to the first central processor 5, store the first RFID transmission signal, and transmit it to the background management system, to complete the inventory of the stored objects such as relays.
[0026] As shown in Figure 1 It can be clearly seen that the bottom surface of the layer plate 1 and the bottom surface of the top plate 12 of the storage cabinet are both installed with the first UHF RFID reader 3. The purpose of such installation is to realize sensing and reading of the first RFID tag 2 on the top of the relay located below, and such installation is also conducive to laying of the antenna of the first UHF RFID reader 3. Figure 2 When the relay 20 attached with the first RFID tag 2 is placed on the layer plate 1 as shown in Figure 1The first RFID data acquisition module 4 on the first side plate 14 shown transmits the data to the first central processing unit 5 for storage, thereby completing the counting of the relays. Since the shelf plate 1 on which the relays are placed is within the coverage area of the antenna of the first UHF RFID reader 3, it is possible to sense and identify all relays that enter its sensing signal coverage area, and there will be no missed sweeping phenomenon that occurs with manual hand sweeping.
[0027] Furthermore, for ease of viewing, this embodiment also includes Figure 1 The first side panel 1 shown is equipped with a display 21, which allows staff to view the storage status of the relays on the corresponding storage cabinets, such as the retrieval and placement time, the number of retrievals and placements within a set time period, and the current number of relays. Of course, this information needs to be provided by the first central processing unit 5, which is responsible for data processing. The specific method of providing this information can be a mature data management system, which can be selected according to actual needs. For example, the storage cabinet provided in this embodiment can store a total of 160 items, the number of shelf boards (8), and the number of items on each shelf board (20). Based on these basic management configurations, a suitable control board or module can be selected. Alternatively, a Raspberry Pi microcomputer can be used as the host to implement all the functions of the first central processing unit 5. The first UHF RFID reader 3 can be connected to the Raspberry Pi microcomputer to realize data transmission, and the data can be displayed on the display 21. In addition, a network communication module (such as a LAN / WiFi / 4G communication module) is installed on the first side panel 14 to connect with the first central processing unit 5 and realize information interaction. This function can also be implemented by the Raspberry Pi microcomputer. Since these are all mature existing technologies and are not necessary technical contents for achieving the technical purpose of this embodiment, they will not be described in detail here.
[0028] Depend on Figure 1 , 2 As can be seen, there are at least two (actually more, usually eight) shelf panels 1 here, distributed vertically and fixed between the first side panel 14 and the second side panel 15 of the storage cabinet; while the top panel 12 is fixed between the top of the first side panel 14 and the second side panel 15.
[0029] To ensure the accuracy of the sensing signal and avoid interference with or erroneous sensing of relays on adjacent storage cabinets, this embodiment specifically installs the sensing antenna of the first UHF RFID reader 3 at the center position of the corresponding shelf plate 1, and... Figure 3The bottom surface of the shelf plate 1 is provided with a first signal shielding baffle 13 extending downward to the lower layer of the shelf plate, so as to surround the antenna of the first UHF RFID reader 3 between the shelf plate 1, the first signal shielding baffle 13, the first side plate 14 and the second side plate 15, thereby blocking the antenna signal of the first UHF RFID reader 3 from being transmitted to the projection area outside the shelf plate 1, and avoiding the induction and identification of the RFID electronic tags of the relays on the adjacent storage cabinets.
[0030] The bottom surface of the top plate 12 is provided with a second signal shielding baffle 16 extending vertically downward, so as to surround the antenna of the first UHF RFID reader 3 between the top plate 12, the second signal shielding baffle 16, the first side plate 14 and the second side plate 15, thereby blocking the antenna signal of the first UHF RFID reader 3 from being transmitted to the projection area outside the top plate 12, and avoiding the induction and identification of the RFID electronic tags of the relays on the adjacent storage cabinets.
[0031] In addition, in order not to interfere with the normal taking and placing of the relays, the first gap 17 for taking and placing the relays is left between the first signal shielding baffle 13 and the lower layer of the shelf plate, and the second gap 18 for taking and placing the relays is left between the second signal shielding baffle 16 and the top layer of the shelf plate.
[0032] In order to facilitate the operation and improve the safety of the operation, the first side plate 14, the second side plate 15, the shelf plate 1 or the top plate 12 (or a plurality of LED lamps can be laid according to the needs) are provided with a lamp strip; a matching infrared human body sensor is connected to the power supply through the lamp strip; and the infrared human body sensor is installed on the first side plate 14 or the second side plate 15 adjacent to the passage. In this way, the light can be turned on when a person comes and turned off after a delay when the person leaves. These can be purchased and selected according to the needs. For example, the infrared human body sensor can be an infrared pyroelectric sensor PIR, and the lamp strip can be an RGB adjustable light strip.
[0033] In order to realize the accuracy and reliability of the warehouse entry and exit, especially the safety, the embodiment further provides a door access system, which comprises Figure 4The second UHF RFID reader 6 is used for sensing and reading the first RFID tag 2 attached to the relay, and the second RFID data acquisition module 7 is matched, which is used for receiving the second RFID transmission signal of the second UHF RFID reader 6 and transmitting to the second central processor 8, storing the second RFID transmission signal, and transmitting to the background management system. The infrared laser sensor is equipped in the access control system, which is used for sensing the entrants and transmitting the alarm signal to the second central processor 8 to control the connection of the electric circuit of the sound and light alarm to issue the alarm sound and light and call the warehouse manager to inspect. Especially, the illegal intrusion warning is issued. In order to cooperate with it, the system also provides a matched turnover box, which is installed with Figure 5 The third UHF RFID reader 9, the third RFID data acquisition module 10 and the third central processor 11 are used for sensing and reading the first RFID tag 2 on the relay, and the third RFID data acquisition module 10 is used for receiving the third RFID transmission signal of the third UHF RFID reader 9 and transmitting the third RFID transmission signal to the third central processor 11, storing the third RFID transmission signal and transmitting to the background management system. Moreover, the turnover box is also attached with the second RFID tag read by the second UHF RFID reader 6 to be sensed and identified by the access control system to prevent the non-special turnover box from entering and leaving.
[0034] Finally, in order to more conveniently manage remotely, the mechanical room relay intelligent inventory management system for railway provided by the embodiment further comprises Figure 6 The local area network switch 19 is used for realizing the communication of the first central processor 5, the second central processor 8 and the third central processor 11 with the cloud server or the background management system via the router.
[0035] Of course, the handheld RFID reader or the RFID reader can also be equipped to facilitate personnel to randomly or regularly inspect and review.
[0036] Through the mechanical room relay intelligent inventory management system for railway provided by the above embodiment, when practicing the work, the newly purchased relay is pasted with the UHF RFID tag with global uniqueness by the staff before entering the warehouse. When the relay passes through the RFID channel door of the mechanical room door (access control system), the UHF RFID reader of the access control system automatically reads all the UHF RFID tag information in a batch and at a long distance without opening the box or scanning one by one. After entering the warehouse, the UHF RFID reader on the storage cabinet reads the UHF RFID tag information on the relay entering the antenna sensing area again to realize the secondary inventory, so that the recheck of the relay entering the warehouse or storage room is completed, and the accuracy and reliability of the entry into the warehouse are ensured.
[0037] In specific practice, the UHF RFID tag information can be set to include the relay model, serial number, purchase batch, access time point, access time period, and other information, to realize fine management. And matched with the background management system, digital archive management is realized, the storage time, quantity, storage location such as A row 3 shelf 2 layer are recorded, and the electronic storage single is automatically generated, completely without manual input.
[0038] When the storage is out, the second UHF RFID tag on the turnover box and the first second UHF RFID tag on the relay in the turnover box are read by the second UHF RFID reader 6 of the access control system, to realize the reading of all information of the out-of-storage, including the turnover box, the relay in the turnover box, and the reading information of the first UHF RFID reader 3 on the storage cabinet, to ensure the consistency and reliability of the out-of-storage information. When the reading information of the first UHF RFID reader 3 on the storage cabinet is inconsistent with the reading information of the second UHF RFID reader 6 of the access control system, the alarm can be sent through the sound and light alarm.
[0039] In addition, in practice, the data acquisition modules, central processors, and network communication functions mentioned in the above embodiments can be realized by Raspberry Pi microcomputers. The specific construction can be carried out according to the functions of the embodiments to build data paths, and the construction of data lines is mature existing technology, which will not be repeated here.
[0040] Finally, it needs to be specially pointed out that the relay intelligent storage cabinet, access control system and the like provided by the above embodiments can be configured with a multi-mode communication module to realize network communication functions such as LAN, WiFi, 4G, to facilitate flexible interaction or transmission or networking of data, such as realizing data interaction management of a single relay intelligent storage cabinet or multiple relay intelligent storage cabinets by the control center, greatly improving the flexibility and convenience of management. The turnover box can also be configured with a Windows platform-based intelligent touch system.
