Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
Fig. 1 is a first schematic flow chart of a method for identifying a filter screen state according to an embodiment of the present invention, as shown in fig. 1, the method for identifying a filter screen state includes the following steps:
step 101: and detecting the RFID label in the target area by using the RFID reading head module to obtain a detection result, wherein a filter screen is arranged in the target area, and a first RFID label is arranged on a filter screen film of the filter screen.
The technical scheme of the embodiment of the invention is applied to the purifier, and the components of the purifier mainly comprise: the wind current that produces by the fan effect passes the filter screen by the air intake and flows to the air outlet, like this, the wind that flows out at the air outlet is exactly the wind that has been purified by the filter screen. Of course, the purifier may have more components to achieve more abundant functions, for example, a high performance material and an activated carbon material for adsorbing fine particles and abnormal flavor macromolecules are disposed between the filter screen and the blower, and TiO for removing odor and smoke may be disposed2A layer and an ultraviolet lamp for removing odor and sterilizing, etc.
In the embodiment of the invention, the type of the filter screen of the purifier is not limited, and the filter screen can be a particulate filter screen or an organic filter screen. Wherein, the particle filter screens are divided into coarse filter screens and fine particle filter screens; the organic filter screens are classified into formaldehyde removal filter screens, deodorization filter screens, activated carbon filter screens, super-light mineralization filter screens and the like. The pollution sources mainly aimed at by each filter screen are different, and the filtering principle is also different.
When the filter screen leaves a factory, the filter screen is provided with a filter screen film for protecting the filter screen, and the shape of the filter screen film is consistent with that of the filter screen or slightly larger than the filter screen film, so that the purpose of protecting the filter screen is achieved. When using the clarifier, need tear the filter screen membrane on the filter screen, just can normally use the clarifier. For this purpose, it is necessary to identify whether the screen film on the screen has been torn off.
In the embodiment of the invention, the first RFID tag is arranged on the filter screen membrane, wherein the mechanism of the RFID tag is based on an RFID technology, the RFID technology is a non-contact automatic identification technology, the target object is automatically identified and relevant data is acquired through radio frequency signals, and manual intervention is not needed in the identification work. The RFID tags are composed of coupling elements and chips, each RFID tag has a unique electronic code and is attached to an object to identify a target object. RFID tags can be classified into: active tags, passive tags, semi-active semi-passive tags.
Taking a passive tag as an example, the process of detecting the RFID tag by the RFID reading head module is as follows: and after the RFID tag enters a magnetic field generated by the RFID reading head module, the RFID tag receives a radio frequency signal sent by the RFID reading head module, and tag information stored in the RFID tag is sent out by means of energy obtained by induced current.
Taking an active tag as an example, the process of detecting the RFID tag by the RFID reading head module is as follows: the RFID label actively sends a radio frequency signal with a certain frequency, and the RFID reading head module reads label information based on the radio frequency signal.
In the embodiment of the invention, the RFID reading head module is arranged at a certain fixed position in the purifier, the area where the RFID reading head module can detect the RFID label is called as a target area, and the range of the target area is smaller and generally does not exceed the space occupied by the purifier body. If the filter screen is provided with the filter screen film, the RFID reading head module can detect a first RFID label arranged on the filter screen film; if the filter screen membrane is torn from the filter screen, the first RFID tag disposed on the filter screen membrane is not detected by the RFID read head module. As can be seen, after the first RFID tag is provided on the filter membrane, the presence or absence of the first RFID tag in the target area can be identified by the RFID reader module. In an embodiment, the RFID tag may be a Near Field Communication (NFC) tag, and accordingly, the RFID reader module is an NFC reader module.
Step 102: determining that the filter screen membrane is disposed over the filter screen when the detection result indicates that the first RFID tag is detected within the target area.
In the embodiment of the invention, the main control board of the purifier is provided with the processing module, as shown in fig. 2, the processing module is in communication connection with the RFID reading head module through a circuit bus, and receives the detection result sent by the RFID reading head module based on the circuit bus. Here, the Circuit bus may be, but is not limited to, a two-wire serial bus (I2C). Then, the processing module judges the detection result, namely: and judging whether the first RFID label is detected.
In the embodiment of the invention, when the detection result shows that the first RFID tag is detected in the target area, the filter screen membrane is determined to be located in the target area, and then the filter screen membrane is determined not to be torn off, namely the filter screen membrane is still arranged on the filter screen. And when the filter screen film is determined to be arranged on the filter screen, outputting prompt information, wherein the prompt information is used for prompting that the filter screen film is arranged on the filter screen. Thus, the user can know that the filter membrane is not torn before the operation of the purifier, and thus can perform the operation of tearing the filter membrane to obtain a normal purifying effect.
In the embodiment of the invention, if the filter screen film is arranged on the filter screen, the wind speed of the air outlet can be influenced, and on the basis, whether the filter screen film is arranged on the filter screen can be further accurately judged according to the first RFID label and the wind speed difference value between the air inlet and the air outlet. Specifically, when the detection result shows that the first RFID tag is detected in the target area, a first wind speed value of the air inlet and a second wind speed value of the air outlet are obtained; calculating a difference between the first wind speed value and the second wind speed value; and when the difference value is larger than or equal to a preset threshold value, determining that the filter screen film is arranged on the filter screen. Here, the preset threshold value can be flexibly set.
Step 103: determining that the filter screen membrane is not disposed on the filter screen when the detection result indicates that the first RFID tag is not detected in the target area.
In the embodiment of the invention, when the detection result shows that the first RFID tag is not detected in the target area, the filter screen membrane is determined not to be in the target area, and the filter screen membrane is further determined to be torn off, namely the filter screen membrane is not arranged on the filter screen. Therefore, the user can know that the filter screen film is torn off before the purifier operates, and the normal purifying effect can be obtained by directly operating the purifier.
It should be understood by those skilled in the art that the steps 102 and 103 of the embodiment of the present invention do not limit the execution order.
