All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, fig. 2 and fig. 3, in one embodiment, the present invention provides an intelligent management system for an electric energy metering secondary warehouse, including:
the RFID system comprises a transmission device 1, an RFID reader-writer 2 and a central control machine 3 which are connected with each other;
the transmission device 1 is used for driving the electric energy equipment to pass through a read-write area of the RFID reader-writer 2;
the RFID reader-writer 2 is used for reading an RFID label arranged on the electric energy equipment and sending a reading result to the central control machine 3, and is also used for writing in and out warehouse data into the RFID label under the control of the central control machine 3;

Wherein, the electric energy equipment is packaged in the turnover box 9, which is convenient for batch transfer.
The RFID (Radio Frequency Identification) tag stores therein various pieces of information of the electric energy device, such as a device type, an in-out state, and the like.
For example, when a certain electric energy device is ready to be put into a warehouse, the electric energy device is placed on the conveying device 1, and the conveying device 1 drives the electric energy device to pass through the read-write area of the RFID reader-writer 2 in the warehouse; in the process of passing through the read-write area, the RFID label on the electric energy equipment is electrified by using the radio frequency signal sent by the RFID reader-writer 2 and sends various information stored by the RFID label; under the control of the central control machine 3, the RFID reader-writer 2 sends the warehousing time and the warehousing state after receiving the information sent by the RFID label; the RFID tag receives and stores the warehousing time and the warehousing status sent by the RFID reader-writer 2. The warehousing state comprises purchasing warehousing, delivering warehousing, returning to the factory and warehousing, returning to the warehouse and warehousing, inventory warehousing, transferring warehousing and the like.
For example, when a certain electric energy device is ready to be taken out of a warehouse, the electric energy device is placed on the conveying device 1, and the conveying device 1 drives the electric energy device to pass through the read-write area of the RFID reader-writer 2 towards the outside of the warehouse; in the process of passing through the read-write area, the RFID label on the electric energy equipment is electrified by using the radio frequency signal sent by the RFID reader-writer 2 and sends various information stored by the RFID label; under the control of the central control machine 3, the RFID reader-writer 2 sends the ex-warehouse time, the ex-warehouse state and the information of the retriever after receiving the information sent by the RFID label; the RFID tag receives and stores the outbound time and the outbound state transmitted from the RFID reader/writer 2. The ex-warehouse state comprises material receiving ex-warehouse, factory returning ex-warehouse, allocation ex-warehouse, inventory shortage ex-warehouse and meter borrowing ex-warehouse.
The central control machine 3 identifies the ID number of the RFID tag and then inquires the traceability condition of the ID number in a corresponding database, so as to determine the in-out state of the RFID tag; for example, when warehousing, when querying that the ID number does not have any traceability condition, it is determined that the electronic device corresponding to the RFID tag is newly purchased, and finally it is determined that the warehousing state is purchasing warehousing. Certainly, in other embodiments, when the tracing condition of the ID number can be queried, the information sent by the RFID tag after being powered on necessarily includes the in-out state, for example, the sent in-out state is a purchasing in-storage, and when going out of the storage, the corresponding out-of-storage state can be directly determined as a material receiving out-of-storage.
The central control machine 3 not only controls the RFID reader/writer 2 to complete corresponding reading and writing operations, but also updates the database according to the reading result, such as inventory updating.
Through the intelligent management system of the electric energy metering secondary storehouse, the RFID system is adopted to record the in and out of the electric energy equipment, the labor is not needed, the labor cost is reduced, and related paper consumables are saved. The accuracy of electric energy equipment record is improved, and asset loss is avoided. The overall efficiency of electrical energy equipment storehouse management is improved.
