Accordingly, based on the above-mentioned linkage digital intelligent Longjing tea refining device, as shown in fig. 2, the digital intelligent Longjing tea refining auxiliary system disclosed in this embodiment includes:
the tag pool 600 is composed of electronic tags, each electronic tag is provided with at least three LED indicator lamps, wherein the color emitted by the first indicator lamp is in the color gamut range of the first color selection material, the color emitted by the second indicator lamp is in the color gamut range of the second color selection material, and the color emitted by the third indicator lamp is in the color gamut range of the fifth color selection material; the attribute of each electronic tag at least comprises a size and a planned path, and the size of the distributed size in the tag pool at least comprises:
a first size between the first screen material and the second screen material.
And a second size within a size range corresponding to the third sieve material.
And a third size within a size range corresponding to the sixth sieve material.
In other words, in this embodiment, the first size, the second size and the third size correspond to three different parallel output channels of the first round screen respectively, and the difference between the three different sizes should be reasonably set so as to facilitate the screening of the first round screen. Further, in order to facilitate observation of the branch state of the second automatic storage hopper that the second round screen machine directly enters without passing through the second air separator, a fourth size within the fourth screening size range and outside the sixth screening size range may be additionally provided.
A reader-writer cluster including a first reader-writer 100 located between the first rotary screen and the first color sorter, a second reader-writer 200 located between the output end of the first color sorter and the input end of the roll cutter, a third reader-writer 300 located between the vibrating tank and the first air separator, a fourth reader-writer 400 located between the second rotary screen and the second air separator, and a fifth reader-writer 500 located between the electrostatic cleaner and the second color sorter.
The connection between each reader/writer in the reader/writer cluster and the control host 160 is used for the control host to execute the following control:
the first reader is instructed to illuminate a first indicator light when an odd number of times a first size of electronic tag is detected, and to illuminate a second indicator light when an even number of times the first size of electronic tag is detected.
And when the second reader is instructed to detect the electronic tag with the first size, calculating the time for the electronic tag with the first size to pass through the roll cutter, and controlling the roll cutter to pause the cutting process when the electronic tag with the first size passes through. After the electronic tag of the first size passes (if necessary, the electronic tag can be detected by the first reader and then the electronic tag can be confirmed to pass safely), the normal processing of the roll cutter can be restored.
And a third indication lamp is lightened when the third reader-writer is instructed to detect the electronic tag with the second size.
And a third indicator lamp is lightened when the fourth reader-writer is instructed to detect the electronic tag with the third size.

Similarly, when the electronic tags with the second size and the third size are detected, checking and ensuring that the third indicator lamp is currently lighted; therefore, the electronic label with the third size is prevented from entering the second automatic storage hopper directly from the second round screen machine without passing through the second winnowing machine, so that the second color sorter makes erroneous judgment and enters the fourth color sorter, and the situation that the corresponding electronic label makes erroneous judgment in the color sorter link of the second color sorter and enters the fourth color sorter due to the fact that the previous readers are not careless can be further avoided. Similarly, if the fourth size exists, the fifth reader/writer needs to perform verification and ensure that the third indicator lamp is currently turned on when detecting the electronic tag of the fourth size.
And indicating the first to fifth readers and writers to record the elapsed time of each electronic tag when the electronic tag of each size is identified.
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, and generates and outputs a first alarm if the actual path of each electronic tag is inconsistent with the planned path. Therefore, the corresponding fault analysis and processing can be conveniently and rapidly executed based on the first alarm. For example: when the actual path corresponding to the electronic tag of the first size is consistent with the planned path corresponding to the electronic tag of the second size or the third size, judging that the screen mesh of the first round screen machine is damaged; or, when the section returned to the roll cutter by the first color sorter is omitted from the actual path corresponding to the electronic tag with the first size, the first color sorter can be judged to have a fault and the like. Preferably, in the process of 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 judging process and the corresponding processing steps can be realized automatically or in a manual intervention mode based on a machine; this is obvious to those skilled in the art based on the disclosure, and will not be described in detail.
In this embodiment, in the first indicator light, the second indicator light and the third indicator light, at most only one indicator light can be in a lighting state at the same time (the initial state may be that each indicator light is in a completely-off state), and the lighting or the off state of each indicator light corresponding to the corresponding electronic tag is controlled through the read-write operation of the reader-writer, so that the shell of each electronic tag is made of a light-transmitting material and is matched with the corresponding electronic tag, so that the color sorter can execute corresponding sorting processing conveniently. The "color gamut range" described in the present embodiment refers to a color range of the corresponding indicator lamp that emits light in the lighted state, and is generally related to the frequency of the light and the color of the lampshade; for example: the first indicator light may be set to a grey color to correspond to the tea leaves of the growth period having a larger size, the second indicator light may be set to a light green color to correspond to the tea leaves of the tender size, and the third indicator light may be set to a yellow or red color similar to the sundries. Furthermore, it is worth mentioning that: because the weight of the electronic tag is usually far greater than that of a single tea, the electronic tag cannot be abandoned as sundries in the air separation process.
In this embodiment, the communication and the read-write operation between the reader-writer and the electronic tag follow the basic working principle of the RFID technology, which is a well-known technology of those skilled in the art, and will not be described in detail.
Preferably, the control host machine of the present embodiment is further configured to calculate a traveling speed of each section of each electronic tag on the actual path, determine whether the traveling speed is within a preset range, and if not, generate a second alarm and output the second alarm. Therefore, the optimization adjustment of parameters related to the running speed of corresponding equipment can be conveniently carried out in time.
Therefore, based on the scheme of the embodiment, after various electronic tags in the tag pool are put into the inclined conveyor along with the tea materials in batches until all the materials are recovered from the fifth color selection, the comprehensive diagnosis of the digital intelligent Longjing tea refining device can be completed; preferably, the diagnosis may be performed only in the initialized state of the digital intelligent Longjing tea refining device, or may be performed on an irregular basis as required.

Based on the reasonable setting, the final outlet of each electronic tag is uniformly treated as a fifth color material by the second color selector, so that the electronic tag is convenient to recycle and reutilize (when the attribute of each electronic tag is set during reutilization, the initial states of the first indicator lamp, the second indicator lamp and the third indicator lamp in each electronic tag are all set to be in an extinction state, and based on convenience, the initial state setting of each electronic tag can be operated based on a handheld mobile reader-writer). Therefore, if the number of the labels recovered by the fifth color selection material is inconsistent with the number of the electronic labels counted by the fifth reader, the abnormal operation state of the second color selection machine can be judged.
7. In the present invention, different sizes substantially correspond to different planned paths. The first reader-writer lights up the first indicator light when the first-size electronic tag is detected for odd times, and lights up the first indicator light and lights up the second indicator light when the first-size electronic tag is detected for even times; therefore, the planning path corresponding to the electronic tag with the first size can be sequentially routed to the two output paths of the first color sorter, the complexity of the system is reduced, and the utilization rate of resources is improved.
8. In the invention, the readers and writers divide and cooperate according to the shunt characteristics of the corresponding electronic tag planning paths, thereby ensuring the stability and reliability of an auxiliary system (for example, the execution omission of the processing functions born by the readers and writers can be greatly reduced), and being convenient for expanding the capacity of a tag pool.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
