As shown in fig. 1, a first embodiment of the present invention provides an RFID-based information reading and writing method, which can be executed by an RFID-based information reading and writing device (hereinafter referred to as a device), and at least includes the following steps:
s101, when receiving a call request of an application, reading a main data value of a main storage area recorded in the RFID label and a standby data value of a standby storage area recorded in the RFID label; the main storage area and the standby storage area are two independent storage areas in the RFID tag, and the main data value and the standby data value are sequentially written in a serial mode.
In this embodiment, the device may be a terminal device having an RFID read/write module, such as an RFID reader, a scanner, a communicator, etc., and performs bidirectional data transmission with the RFID tag by using a radio frequency method, such as reading data recorded in the RFID tag or writing data into the RFID tag.
The storage area in the RFID tag has a plurality of separate physical sectors that can be used to store data predefined by the user. The main storage area and the spare storage area are respectively arranged on different physical sectors, and information to be stored can be sequentially written in a serial mode to obtain a main data value and a spare data value.
In this embodiment, the application may be a wired or wireless network application that initiates a data invocation request to the device and performs a predefined action based on the data value returned from the device.
S102, when the main data value is different from the standby data value, comparing the main data value with the standby data value with a preset reasonable interval respectively to obtain a comparison result.
In this embodiment, in the information storage process, the data that is normally written into the primary storage area and the spare storage area sequentially in a serial manner is the same. However, a certain time is required for writing information into the RFID tag, abnormal situations such as power failure are likely to occur during writing, since only one storage area is performing writing operation when a power failure occurs, the written information of the storage area is erroneous, and the other storage area is normally written after being powered on, so the written information is correct. The primary data value and the alternate data value are different indicating a loss or exception to the read data value.
In the process of reading and writing the non-contact information by adopting the RFID radio frequency mode, data errors are easy to occur due to power failure, and the main data value and the standby data value need to be compared with a preset reasonable interval so as to judge whether the corresponding storage area is powered down or not.
S103, returning a correct data value to the application initiating the data call according to the comparison result, and rewriting the RFID label according to the correct data value.
In this embodiment, the storage area in which the write operation is being executed when the power failure occurs can be determined by comparing the results, so as to obtain the storage area in which the correct data value is located and return the data value in the storage area to the application.
Particularly, after the correct data value is obtained, the RFID tag is rewritten according to the correct data value, so that the correct data value is written into the two storage areas, and the data can be conveniently and normally read next time.
In one particular embodiment: when one of the main data value and the standby data value is not in the reasonable interval, acquiring a correct data value and an incorrect data value, and returning the correct data value to an application initiating data calling; and writing the correct data value into the storage area corresponding to the incorrect data value. Wherein the correct data value is a data value in the reasonable interval; the incorrect data value is a data value which is not in the reasonable interval;
in the above embodiment, when one of the main data value and the spare data value is not in the reasonable interval, it indicates that an abnormal condition occurs in the writing process for the data value that is not in the reasonable interval, and the data value should be discarded. And returning the data value in the reasonable interval as a correct data value to the application and writing the data value into a storage area where the incorrect data value is located.
In another specific embodiment: when the main data value and the standby data value are both in the reasonable interval, returning the main data value to the application initiating data calling; writing the primary data value to the spare storage area.
In the above embodiment, when both the main data value and the spare data value are in the reasonable interval, it indicates that no power failure occurs in the writing process, and at this time, the main data value written first is returned to the application as a correct data value and the data value is written into the spare storage area.
It should be noted that, the situation that neither the main data value nor the spare data value is in the reasonable interval is unlikely to occur. This is because in the information writing process, if the power failure does not occur, both the main data value and the spare data value are normal and are necessarily in the reasonable interval. In the event of a power loss, since data is written in a serial manner, it is inevitable that only one memory region is performing a write operation: for example, when a power failure occurs, a main data value is being written into the main storage area, the main data value is continuously written after power-on, and then a spare data value is written into the spare storage area, where the main data value is abnormal and the spare data value is normal, that is, the spare data value is in the reasonable interval and the main data value is not in the reasonable interval. For another example, when a power failure occurs, a spare data value is being written into the spare storage area, the spare data value continues to be written after power is turned on, and since the main data value is written into the main storage area before the power failure occurs, the spare data value is abnormal and the main data value is normal, that is, the main data value is in the reasonable interval, and the spare data value is not in the reasonable interval.
In the embodiment, the information to be stored is sequentially written into the two independent storage areas in the RFID tag in a serial mode, so that when the writing operation is performed, the next partition can be written only after the writing operation of one partition is completed, and thus, the situation that when the writing operation is performed, data of only one storage area is abnormal and the other storage area retains correct information no matter abnormal conditions such as power failure occur at any time can be ensured. Therefore, backup protection of the written information is realized, and the loss of effectiveness of the RFID caused by abnormal data loss or even complete data loss due to power failure is prevented. By comparing the main data value and the standby data value with the preset reasonable interval respectively, the correct data value stored before power failure can be obtained, and abnormal information in the RFID tag is rewritten, so that the next time of information reading is facilitated, and normal identification and use of application are guaranteed.
Referring to fig. 2, on the basis of the foregoing embodiment, in a preferred embodiment, when the main data value and the spare data value are the same, it indicates that no power failure occurs during information reading and writing, and no misrecognition and data error occur, and then the main data value is returned to the application initiating the data call.
Referring to fig. 3, fig. 3 is a flowchart of an RFID-based information reading and writing method according to a second embodiment of the present invention, where the method is described from the writing side, and includes the following steps:
s201, obtaining information to be stored;
s202, writing the information into a main storage area in the RFID tag to obtain a main data value;
and S203, after the information is written in the main storage area, writing the information into a standby storage area in the RFID label to obtain a standby data value.
In this embodiment, after writing the information into the main storage area in the RFID tag and obtaining the main data value, the method further includes: the primary data value in the primary storage area is checked. Error codes and conflicts can be prevented through verification, the read-write reliability and stability of data are improved, and the accuracy is ensured. Of course, after the spare data value is obtained, the spare data value may be further verified, which are all within the scope of the present invention.
In the embodiment, the information to be stored is sequentially written in the two independent storage areas in the RFID tag in a serial mode, so that when the writing operation is performed, the next partition is written only after the writing operation of one partition is completed, and thus, it can be ensured that when the writing operation is performed, only the data of one storage area is abnormal under the abnormal conditions such as power failure at any time, and the other storage area retains correct information. Therefore, backup protection of the written information is realized, and the condition that the validity of the RFID label is lost due to abnormal data or even complete data loss caused by power failure is prevented.
