By this, based on the intelligent dragon well tea refining device of digit of above-mentioned linkage, as shown in fig. 2, the intelligent dragon well tea refining auxiliary system that this embodiment discloses includes:
a label pool 600 composed of electronic labels, each electronic label having at least three LED indicator lamps, wherein the color emitted by the first indicator lamp is in the color gamut of the first color material, the color emitted by the second indicator lamp is in the color gamut of the second color material, and the color emitted by the third indicator lamp is in the color gamut of the fifth color material; the attributes of each electronic tag at least comprise a size and a planned path, and the sizes distributed in the tag pool at least comprise:
a first size between the first screen material and the second screen material.
A second size within a size range corresponding to the third sifting material.
A third size within a size range corresponding to the sixth screening material.
In other words, in this embodiment, the first size, the second size, and the third size respectively correspond to three different parallel output channels of the first circular screen machine, and the difference between the three different sizes should be set reasonably so as to facilitate the first circular screen machine to perform screening. Furthermore, in order to facilitate observation of the state of the branch of the second round sifter directly entering the second automatic storage hopper without passing through the second winnowing machine, a fourth size within the range of the fourth sifting size and outside the range of the sixth sifting size may be additionally provided.
The reader-writer cluster comprises a first reader-writer 100 positioned between a first rotary screen machine and a first color selector, a second reader-writer 200 positioned between the output end of the first color selector and the input end of a roll cutting machine, a third reader-writer 300 positioned between a vibration groove and a first air classifier, a fourth reader-writer 400 positioned between a second rotary screen machine and a second air classifier, and a fifth reader-writer 500 positioned between an electrostatic impurity remover and the second color selector.
The connection between each reader and the control host 160 in the reader cluster is used for the control host to execute the following control:
and indicating the first reader-writer to light the first indicator light when the electronic tag of the first size is detected for the odd times, and to turn off the first indicator light and light the second indicator light when the electronic tag of the first size is detected for the even times.
And instructing the second reader-writer to calculate the time when the electronic tag of the first size passes through the roll cutting machine when the electronic tag of the first size is detected, and controlling the roll cutting machine to pause the cutting processing when the electronic tag of the first size passes through. After the electronic tag of the first size passes through (if necessary, the electronic tag can be confirmed to pass through safely after the electronic tag is detected again by the first reader-writer), normal processing of the roll cutting machine can be resumed.
And the third indicator lamp is lightened when the third reader-writer is instructed to detect the electronic tag with the second size.
And the fourth reader-writer is instructed to light the third indicator lamp when detecting the electronic tag with the third size.
When the fifth reader-writer is instructed to detect the electronic tag with the first size, the current indicator lamp (usually, the second indicator lamp is turned off, and if the first color selector fails or the first reader-writer fails, the first indicator lamp may be the first indicator lamp corresponding to the current indicator lamp) is turned on, and the third indicator lamp is turned on; so as to prevent the electronic tag with the first size from entering the fourth color sorting machine due to the misjudgment of the second color sorting machine. Similarly, when the electronic tags of the second size and the third size are detected, the third indicator light is checked and ensured to be lighted currently; therefore, the electronic tags with the third size are prevented from directly entering the second automatic storage hopper from the second circular screen without passing through the second air separator, so that the electronic tags enter the fourth color sorting machine due to the fact that the second color sorting machine makes a wrong judgment, and the electronic tags can be further prevented from entering the fourth color sorting machine due to the fact that the corresponding electronic tags make a wrong judgment in the color sorting link of the second color sorting machine due to careless mistakes of the previous reader-writers. Similarly, if the fourth size exists, when the electronic tag of the fourth size is detected, the fifth reader-writer needs to perform verification and ensure that the currently lighted third indicator light is operated.
And indicating the first to fifth readers to record the time of each electronic tag when the electronic tags of all sizes are identified.
And the control host acquires the elapsed time of each electronic tag from the first reader-writer to the fifth reader-writer, analyzes the actual path of each electronic tag, judges whether the actual path of each electronic tag is consistent with the planned path or not, and generates a first alarm and outputs the first alarm if the actual path of each electronic tag is not consistent with the planned path. Therefore, corresponding fault analysis and processing can be conveniently and rapidly executed on the basis of the first alarm. For example: when the actual path corresponding to the electronic tag with the first size is consistent with the planned path corresponding to the electronic tag with the second size or the third size, the screen of the first circular screen machine can be judged to be damaged; or, when the segment returned to the roller cutting machine by the first color selector is omitted from the actual path corresponding to the electronic tag with the first size, it can be determined that the first color selector has a fault or the like. Preferably, during the analysis and processing, the size and the actual path of the corresponding electronic tag and the actual state switching process of the first, second and third indicator lamps need to be comprehensively judged. The comprehensive judgment process and the corresponding processing steps can be automatically realized based on a machine or manually intervened; this is obvious to a person skilled in the art based on the disclosure and will not be described in detail.
In this embodiment, at most one of the first indicator light, the second indicator light, and the third indicator light may be in a turned-on state (an initial state may be that each indicator light is in a fully-off state) at the same time, and the turned-on or turned-off state of each indicator light corresponding to the corresponding electronic tag is controlled by the read-write operation of the reader. The color gamut described in the present embodiment refers to the color gamut of the corresponding indicator light in the on state, and generally relates to the frequency of light and the color of the lamp shade; for example: the color of the first indicator light can be set to be slightly gray to correspond to tea leaves with slightly longer and larger sizes in the growing period, the second indicator light can be set to be slightly green to correspond to tea leaves with slightly smaller sizes, and the third indicator light can be set to be slightly yellow or slightly red and similar to sundries. It is also worth mentioning that: since the weight of the electronic tag of the invention is usually much larger than that of a single tea leaf, the electronic tag is not discarded as impurities in the winnowing process.
In this embodiment, the communication and read-write operation between the reader and the electronic tag follow the basic working principle of the RFID technology, and are well known to those skilled in the art and will not be described in detail.
Preferably, the control host of this embodiment is further configured to calculate a traveling speed of each segment of each electronic tag on the actual path, determine whether the traveling speed is within a preset range, and generate and output a second alarm if the traveling speed is not within the preset range. Therefore, the parameters of the corresponding equipment related to the running speed can be conveniently and timely optimized and adjusted.
Therefore, based on the scheme of the embodiment, the comprehensive diagnosis of the digital intelligent Longjing tea refining device can be completed by putting various electronic tags in the tag pool together with tea materials into the inclined conveyor in batches until all the electronic tags are recovered from the fifth color material selection; preferably, the diagnosis can be implemented only in the initialization state of the digital intelligent dragon well tea refining device, or can be implemented on an irregular basis as needed.

4. Similarly, whether the running states of the first color selector and the second color selector are normal or not can be quickly detected by judging whether the actual path of the corresponding electronic tag is consistent with the planned path or not.
5. The invention reduces the cost and the complexity of the system by only arranging the reader-writer on the critical path. For example: the reader-writer can be omitted from being arranged on a direct connection branch between the second rotary screen machine and the second automatic discharging hopper. Therefore, for the electronic tag with the fourth size, the control host can determine through logic: when the second material is not passing through the fourth reader-writer, the second material can be judged to be the seventh, eighth or ninth screening material to enter the second automatic storage hopper.
6. Based on the reasonable setting, the final outlet of each electronic tag is uniformly regarded as a fifth color material by the second color sorter, so that the electronic tags are convenient to recycle and reuse (when in secondary utilization, the initial states of the first indicator light, the second indicator light and the third indicator light in each electronic tag are all set to be in a turned-off state when the attribute of each electronic tag is set, and the initial state setting of each electronic tag can be operated based on a handheld mobile reader-writer based on convenience consideration). Therefore, if the number of the tags recovered through the fifth color sorting is not consistent with the number of the electronic tags counted by the fifth reader, it can be determined that the operating state of the second color sorter is abnormal.
7. In the present invention, different dimensions substantially correspond to different planned paths. The first reader-writer lights a first indicator lamp when detecting the electronic tag of the first size for odd times, and lights the first indicator lamp and lights a second indicator lamp when detecting the electronic tag of the first size for even times; therefore, the planned path corresponding to the electronic tag with the first size can successively pass through the two output paths of the first color selector, the complexity of the system is reduced, and the utilization rate of resources is improved.
8. In the invention, the readers perform division and cooperation according to the distribution characteristics of the planned paths of the corresponding electronic tags, so that the stability and reliability of the auxiliary system are ensured (for example, the execution omission of processing functions undertaken by the readers can be greatly reduced), and the capacity of the tag pool is conveniently expanded.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
