Abstract
The invention discloses a kind of anti-error writing methods of RFID tag of air purifier strainer, including：Strainer and RFID tag are mounted on together in air purifier and are contacted with push switch；Strainer depresses push switch, and detection circuit transmits fixed level signal to MCU；Whether the more above-mentioned level signals of MCU are consistent with its predetermined level signal, can be read and write when the two is consistent；RFID read-write module postpones 500ms after the power is turned on, then reads the information of RFID tag record；The identity information that the identity information of this reading was read with last time is compared, can be written when the two is consistent.The present invention is by detecting whether RFID tag in normal condition controls the read-write of data, when strainer installation is not in place, MCU can detect that RFID tag is not on correct position, therefore RFID read-write module will not carry out reading and writing data to RFID tag, label substance will not be changed by mistake, and then ensure that the accuracy for the strainer information that RFID tag is recorded.
Description
Technical field
The present invention relates to air purifier technical fields, more particularly to a kind of RFID tag for air purifier strainer
Anti-error writing method.
Background technology
Currently, certain air purifiers record strainer model, design parameter, use using the strainer with RFID tag
Service life, using information such as durations, then its data is written and read by special equipment, to understand the working condition of strainer.But
Product research and development and find in actual use, when RFID tag plays pendulum, write-in data be possible to meeting
Cause data entanglement occur, and then affects the accuracy of record strainer information.
Invention content
In order to solve the above technical problems, writing control the invention discloses a kind of RFID tag of air purifier strainer is anti-error
Method includes mainly：
A, RFID tag is fixed on strainer first, then strainer is mounted in air purifier and is opened with a push type
Close contact, the MCU of the push switch and air purifier is connected by electric signal, RFID tag by RFID read-write module with
MCU electric signals connect；
B, screen location installation it is correct when, push switch can be depressed and connect detection circuit, at this time RFID tag to
MCU transmits fixed level signal；Conversely, if push switch is not depressed, illustrate that screen location installation is incorrect, inspection
The level signal that slowdown monitoring circuit is sent to MCU does not change；
C, RFID read-write module read-write RFID tag record information before, MCU level signals more above-mentioned first with
Whether its predetermined level signal is consistent, if the two is consistent, can read and write；If inconsistent, not read and write；
D, when that need not be read and write to RFID tag, MCU disconnects the power supply of RFID read-write module, prevents from accidentally writing in label
Hold；It when needing read-write, is just powered on to RFID read-write module, and postpone 500ms after the power is turned on, waits for that RFID read-write module is completed just
It is first resetted after beginningization, then reads the information of RFID tag record again；
E, the identity information that was read with last time of identity information of this reading is compared, it, can be with if the two is consistent
Write-in；If inconsistent, be not written, to prevent there is entanglement when write-in data.
The beneficial effects of the invention are as follows：
The present invention by detecting whether RFID tag in normal condition controls the read-write of data, when strainer installation less than
When position, MCU can detect that RFID tag is not on correct position, therefore RFID read-write module will not carry out RFID tag
Reading and writing data, label substance will not be changed by mistake, and then ensure that the accuracy for the strainer information that RFID tag is recorded.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.
The anti-error writing method of RFID tag of the air purifier strainer of the present embodiment includes mainly the following contents：
A, RFID tag is fixed on strainer first, then strainer is mounted in air purifier and is opened with a push type
Close contact, the MCU of the push switch and air purifier is connected by electric signal, RFID tag by RFID read-write module with
MCU electric signals connect.
Wherein, the installation fixed form of strainer and air purifier is ordinary skill in the art means, RFID tag
Position on strainer does not have particular/special requirement, and the mounting means of RFID read-write module is also without particular/special requirement, as long as can guarantee just
Often read-write RFID tag content.
B, the effect of push switch is that whether RFID tag is installed in place detection strainer in other words, when screen location is installed
When correct, push switch can be depressed and connect detection circuit, RFID tag transmits fixed level signal to MCU at this time；
Conversely, if push switch is not depressed, illustrate that screen location installs incorrect, the level that detection circuit is sent to MCU
Signal does not change.
C, RFID read-write module read-write RFID tag record information before, MCU level signals more above-mentioned first with
Whether its predetermined level signal is consistent, if the two is consistent, can read and write；If inconsistent, not read and write.
Predetermined level signal was determined at MCU circuit design initial stages, for example, when can be designed as push switch pressure
It is high level signal, is low level signal when not depressing；Or in turn, it is low level signal when pressure, when not depressing
It is high level signal, as long as the decision logic of program is consistent with circuit, has no effect on the judgement of final result.
D, when that need not be read and write to RFID tag, MCU disconnects the power supply of RFID read-write module, prevents from accidentally writing in label
Hold；It when needing read-write, is just powered on to RFID read-write module, and postpone 500ms after the power is turned on, waits for that RFID read-write module is completed just
It is first resetted after beginningization, then reads the information of RFID tag record again, can ensure occur when reading and writing data in this way
Entanglement.
E, it before data being written, needs first to be compared the identity information that the identity information of this reading was read with last time,
If the two is consistent, illustrates that normal steady state is not replaced and be in RFID tag, data can be written at this time；If differing
It causes, then illustrates that unsteady state has been replaced or be in RFID tag, data cannot be written at this time, asked to prevent there is data entanglement
Topic.
The present invention by detecting whether RFID tag in normal condition controls the read-write of data, when strainer installation less than
When position, MCU can detect that RFID tag is not on correct position, therefore RFID read-write module will not carry out RFID tag
Reading and writing data, label substance will not be changed by mistake, and then ensure that the accuracy for the strainer information that RFID tag is recorded.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
