The customer can acquire the information of the articles in real time, know the delivery state of the articles, and improve the delivery speed and accuracy.

In one embodiment of the present invention, the arranging the RFID read-write device and disposing the RFID tag on the object to be sensed in the area to be sensed includes:

s11: obtaining a layout diagram of a region to be sensed, wherein the layout diagram comprises the size, the shape, the partition and a possible shielding object or interference source of the region to be sensed;

The working principle of the technical scheme is as follows: firstly, obtaining a layout diagram of a region needing to be perceived; the layout includes the size, shape, partition of the perceived area, and the possible presence of occlusions or sources of interference; RFID signal testing is performed using one or more RFID tags within the sensing region. Determining the transmission range and transmission quality of the RFID signal by testing the signal intensity and transmission distance of different positions; and determining the optimal mounting position of the RFID read-write equipment according to the result of the RFID signal test. Selecting those locations that provide the best signal coverage and transmission quality throughout the sensing region; and (5) according to the characteristics and the storage position of the article, making an installation plan of the RFID tag. Determining where to mount the RFID tag on the item to ensure a reliable signal, considering the size, material and manner of storage of the item; and associating the commodity information corresponding to the RFID tag with the RFID tag through the inventory management system. Each RFID tag corresponds to a unique commodity information, including commodity codes, names, specifications, quantity and the like; after the association is completed, the RFID tag is set according to the storage position of the commodity. The RFID tag is attached or affixed to the corresponding item. For example, assume that the warehouse is a rectangular space, divided into rows and columns, and that there are some columns and stacks of goods. Several key locations within the sensing area are selected for RFID signal testing. The center position of each partition or the midpoint position of each row or each column may be selected. RFID read-write devices are installed at these locations and several items are equipped with RFID tags, which items represent the type of goods that are common in warehouses. From the result of the RFID signal test, we can determine the best RFID reader mounting location. By analyzing the signal strength and coverage, we can determine which locations can most effectively perceive all RFID tagged items. It may be necessary to adjust the placement of the devices or increase the number of devices to ensure coverage of the entire perceived area. The hypothetical warehouse houses various types of goods, including electronic products, which are generally small and do not interfere with metal or electronic equipment. To ensure that the RFID tag can be effectively read, the tag may be mounted on a package of electronic products or on an inner foam protective layer. Therefore, normal use of goods is not affected, and the readability of the label can be ensured. For food products, hygienic and waterproof properties of the label need to be considered.

These signals may penetrate air and nonmetallic materials and propagate to surrounding areas. An antenna in the RFID tag receives electromagnetic wave signals sent by the RFID read-write equipment. The antenna transmits the received signal to circuitry in the RFID chip. And the circuit in the RFID chip analyzes the received signals and performs corresponding operation according to a preset rule. For read-only tags, the chip may return only the information stored in the tag. For read-write tags, the chip is capable of receiving and processing instructions from a read-write device, such as reading or writing data. After receiving the response signal of the RFID tag, the read-write equipment requests data from the tag by sending a read instruction. Circuitry in the read-write device converts the instructions into corresponding wireless signals. When the RFID tag receives the reading instruction, the response device starts, and the stored data information is sent back to the RFID reading and writing device through a wireless signal. Circuitry in the tag converts the data into a corresponding signal for transmission.

The wireless transmission mode does not need physical contact, and can realize rapid transmission and sharing of data in a certain range. In addition, the data in the tag can be stored for a long time, so that subsequent access and inquiry are convenient.

In one embodiment of the invention, the RFID read-write equipment decodes the received signal to obtain the data information stored in the RFID; the data information includes a unique identifier of the object and location information; comprising the following steps:

Before receiving the signal, the device first detects the preamble bit; the preamble bits are used to synchronize and identify a series of specific bits from which the signal begins; according to the RFID standard and protocol, the device converts the received signal into corresponding binary data. Including converting the wireless signal to a digital signal for subsequent parsing and processing; the device parses the frame structure of the RFID signal based on the decoded binary data. The frame structure includes a frame initiator, a data field, and a checksum.
