After receiving the appliance receiving request, the material management terminal 104 acquires the corresponding target appliance according to the appliance receiving request, and acquires the target radio frequency signal corresponding to the target appliance, which is acquired by the terminal 102.

In an embodiment, as shown in fig. 2, a radio frequency signal acquiring method is provided, which is described by taking the application of the method to the terminal 102 in fig. 1 as an example, and includes the following steps:

s201: and transmitting the first radio frequency signal according to a preset power range.

The Radio Frequency signal is a Radio wave modulated and having a certain transmission Frequency, and can be identified by a Radio Frequency Identification (RFID) device, and the working principle of the RFID is to perform non-contact data communication between a reader and a tag, thereby achieving the purpose of identifying a target. The complete RFID is mainly composed of three parts, including: tags, readers, and antennas. The tag comprises a transceiving antenna, an AC/DC circuit, a demodulation circuit, a logic control circuit, a memory and a modulation circuit; the reader is a device for reading out the information in the tag or writing the information required to be stored in the tag into the tag; the antenna is used for sending radio frequency signals to the label and receiving response signals and label information returned by the label. In practical applications, in order to ensure that the first rf signal is transmitted only to the target range, the transmission power of the rf signal needs to be controlled, that is, the first rf signal is transmitted according to a certain power range.

S202: and scanning to obtain a second radio frequency signal.

The second radio frequency signal is obtained by reflecting the first radio frequency signal through a radio frequency tag, the radio frequency tag refers to an RFID electronic tag, and the electronic tag and the reader are coupled in space (without contact) through a coupling element; and in the coupling channel, energy transfer and data exchange are realized according to the time sequence relation. Therefore, when the radio frequency tag is scanned, the first radio frequency signal is emitted, and then the second radio frequency signal reflected by the radio frequency tag from the first radio frequency signal is received by the RFID device, which is equivalent to reading the data in the electronic tag by the reader.

S203: and filtering the second radio frequency signal based on the signal attribute of the second radio frequency signal to obtain a target radio frequency signal.

In practical applications, when a first rf signal is transmitted, all rf tags located in an area where the power range of the first rf signal can be transmitted will reflect a corresponding second rf signal, so that the obtained second rf signal needs to be filtered to screen out a target signal corresponding to a target to be identified. Specifically, the signal attribute includes at least one of signal strength, scanning duration, type of the radio frequency signal, number of the radio frequency signals, target data corresponding to the radio frequency signal, code attribute, and matching information of the radio frequency signal.

The signal strength is used for representing the signal strength of the radio frequency signal, and the scanning duration refers to the duration of completely receiving the second radio frequency signal. In practical application, the radio frequency tags can be of various types corresponding to different types of data information, so that the types of the obtained radio frequency signals are also different, and the radio frequency signals different from the target radio frequency signals can be screened out according to the types of the radio frequency signals and the number of the corresponding radio frequency signals. The target data corresponding to the rf signal refers to data related to an identification target corresponding to the rf signal, for example, if the rf signal is a signal of an article to be received, the target data corresponding to the rf signal is used to indicate related information of the article to be received, such as a receiving range. The code attribute refers to a size attribute of a code corresponding to the radio frequency signal, and specifically, if there are multiple types of radio frequency signals corresponding to the target to be identified, the code attributes of the radio frequency signals obtained by the same target to be identified should be the same. The matching information of the radio frequency signals refers to the incidence relation between the radio frequency signals corresponding to the target to be identified, and if the incidence relation corresponding to the second radio frequency signal obtained by code scanning is inconsistent with the incidence relation in the data information of the target to be identified, the radio frequency signals are not the target radio frequency signals.

According to the radio-frequency signal obtaining method, the first radio-frequency signal is transmitted according to the preset power range, the second radio-frequency signal is obtained through scanning, accordingly, the second radio-frequency signal is filtered based on the signal attribute of the second radio-frequency signal to obtain the target radio-frequency signal, errors of the radio-frequency signal caused by environmental factors can be avoided, and the safety of the signal is guaranteed.

In an embodiment, the filtering the second rf signal to obtain the target rf signal based on the signal property of the second rf signal includes at least one of: filtering the second radio frequency signal according to the signal intensity of the second radio frequency signal to obtain a target radio frequency signal; or filtering the second radio frequency signal according to the scanning duration of the second radio frequency signal to obtain a target radio frequency signal; or filtering the second radio frequency signal to obtain a target radio frequency signal based on the type of each radio frequency signal in the group of radio frequency signals and the number of the radio frequency signals; or receiving target data corresponding to the transmitted radio frequency signal; filtering the second radio frequency signal according to the target data to obtain a target radio frequency signal; or acquiring a code attribute corresponding to the target data; filtering the second radio frequency signal to obtain a target radio frequency signal; or acquiring matching information of the target radio frequency signal; and filtering the second radio frequency signal to obtain a target radio frequency signal.

Specifically, the second radio frequency signal is filtered according to the signal intensity of the second radio frequency signal to obtain a target radio frequency signal, which indicates that the signal intensity of the target radio frequency signal is greater than a certain intensity threshold, in practical application, the greater the signal intensity of the second radio frequency signal reflected by the radio frequency tag, the closer the corresponding radio frequency tag is to the scanning device is, and therefore, the target radio frequency tag can be identified, and the corresponding radio frequency signal is the target radio frequency signal.

According to the scanning time length of the second radio-frequency signal, the second radio-frequency signal is filtered to obtain a target radio-frequency signal, the scanning time length of the target radio-frequency signal is larger than a certain time length threshold value, in practical application, the stronger the signal intensity of the radio-frequency signal is, the longer the scanning time length of the radio-frequency signal is, therefore, for the radio-frequency signal of which the scanning time length is larger than the certain time length threshold value, the corresponding radio-frequency tag is represented to be closer to the scanning device, the radio-frequency tag can be regarded as the target radio-frequency tag, and the corresponding radio-frequency signal is the target radio-frequency signal.

The second radio frequency signals are filtered based on the types of the radio frequency signals in the group of radio frequency signals and the number of the radio frequency signals to obtain target radio frequency signals, which means that the number of the signal types in the target radio frequency signals meets a certain requirement, for example, in logistics receiving, trays of receiving devices and transporting devices are different in coding rules, formed radio frequency tags are different, so that the signal types of the corresponding radio frequency signals are different, if the group of signals is required to include the signal types corresponding to the trays of the receiving devices and the transporting devices, the scanned second radio frequency signals only contain the radio frequency signals of the signal types corresponding to the receiving devices or only contain the signal types corresponding to the trays of the transporting devices, the requirements are not met, and only the radio frequency signals of the signal types corresponding to the trays simultaneously containing the receiving devices and the transporting devices are determined to be the target radio frequency signals.

And receiving target data corresponding to the issued radio frequency signal, and filtering a second radio frequency signal according to the target data to obtain a target radio frequency signal, wherein the target radio frequency signal refers to coded data obtained according to a coding rule of the radio frequency tag, and the coded data is used for indicating whether the radio frequency tag corresponding to the second radio frequency signal is a tag needing to be scanned or not. Taking logistics receiving as an example, the encoded data may represent a label of the goods, and only the label within a certain range is the goods that need to be received, so that the radio frequency signal corresponding to the current encoded data is the target radio frequency signal.

And acquiring a code attribute corresponding to the target data, and filtering the second radio frequency signal to obtain a target radio frequency signal, wherein the code attribute refers to a coding attribute of the radio frequency tag, specifically, the coding attribute can be divided into a capital attribute and a small-case attribute, and the coding attributes of the same object should be the same, so that if the code attributes are different, the corresponding radio frequency signal is invalid.

Acquiring matching information of a target radio frequency signal, and filtering a second radio frequency signal to obtain the target radio frequency signal, wherein the matching information refers to a correlation relationship between a group of radio frequency signals, taking logistics receiving as an example, the radio frequency signal corresponding to the goods to be received and the radio frequency signal corresponding to the tray of the carrying appliance are correlated, and if no correlation exists between the radio frequency signal corresponding to the goods to be received and the radio frequency signal corresponding to the tray of the carrying appliance in the scanned second radio frequency signal, it indicates that the current radio frequency signal is invalid.

In the above embodiment, the second radio frequency signal is filtered based on the signal attribute of the second radio frequency signal to obtain the target radio frequency signal, so that an error signal caused by an environmental factor can be eliminated, and the accuracy of the target radio frequency signal is ensured.
