Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and more specifically, to a sorting method and a sorting device for HPLC modules. Background Art

[0002] With the development of the power industry, electric meters are installed in every household, so the traditional manual meter reading has caused great cost and work efficiency pressure on power companies. In order to solve this technical problem, the power data in the meter is read through the HPLC (low voltage power line high speed carrier communication) module and uploaded to the main control center of the power company. The power data is summarized and managed by the main control center, thereby reducing costs and improving work efficiency.

[0003] However, since the service life of the electric meter is limited, usually 3-5 years, it needs to be replaced, and the HPLC module is often configured together with the electric meter, so it is also discarded in large quantities, but the HPLC module may be in normal working condition, thus causing great waste. However, if the HPLC is directly recycled, the damaged module will cause troubles in subsequent use, and it is impossible to perform corresponding recycling configuration according to actual needs.

[0080] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

In addition, it should be understood that in the description of the embodiments of the present invention, the words "first", "second", etc. are only used to distinguish the purpose of description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0082] The present invention provides a method for sorting HPLC modules, such as Figure 1 As shown, the sorting method of the HPLC module includes:

[0083] S10) performing a functional test on the HPLC module and generating a test result;

[0084] S20) determining the normal function of the HPLC module based on the test results;

[0085] S30) performing classification processing on the HPLC modules based on normal functions to obtain classification information;

[0086] S40) performing a sorting operation on the HPLC module based on the classification information.

[0087] In an embodiment of the present invention, the sorting method provided by the embodiment of the present invention is applied to a sorting device of an HPLC module, wherein the HPLC module can be a single-phase HPLC module, a three-phase HPLC module or a concentrator HPLC module, and the sorting device is provided with an HPLC slot matching the aforementioned types of HPLC modules, and various types of HPLC modules can be inserted into the matching slots. The sorting device is also provided with a display screen, and three signal lights are provided on the display screen, namely, a detection signal light, a fault signal light and a normal signal light. When a technician in this field inserts the HPLC module into the corresponding slot, the power of the sorting device is turned on, and the device starts to detect the HPLC module, then the detection signal light is on, and after the detection is completed, the corresponding signal light is lit according to the detection result, for example, if the detection result is normal, the normal signal light is lit, and if the detection result is a fault, the fault signal light is lit.

[0088] In the prior art, when sorting HPLC modules, the sorting device checks their necessary functions. If the necessary functions are normal, they are classified as normal HPLC modules and sorted out for reuse. However, in actual application, only checking the necessary functions and ignoring other functions may underestimate their value, thereby damaging the interests of enterprises.

[0089] In order to sort them more accurately and improve the recycling value of the enterprise, in the embodiments provided by the present invention, Figure 2 As shown, the sorting device also includes a testing unit, a determining unit, a grading unit and a sorting unit. When a technician in this field inserts the HPLC module into the corresponding slot, the testing unit of the sorting device is used to test the HPLC module and generate a test result, such as testing its data interaction function, testing its data transmission function and testing its data storage function, so that the sorting device can perform subsequent sorting work on the HPLC module; for example, when the HPLC module is inserted into the corresponding slot, the main control module of the testing unit sends the analog meter data to the HPLC module through the serial port and the network port, and then the HPLC module sends a carrier signal and returns the data to the main control module, thereby realizing a closed communication loop, and by parsing the feedback data, it is possible to determine whether there is a fault in the function of the HPLC module, and generate a test result of whether there is a fault.

[0090] Specifically, the HPLC module includes multiple functions, and the inspection unit of the sorting device can detect all functions of the HPLC module. For example, the main control module of the inspection unit can send analog data to the HPLC module according to a preset communication protocol to check whether its data interaction function is faulty; after receiving the analog data, the HPLC module performs carrier processing on it and feeds back the data to the main control module through a power line (such as a 220V power line) to check whether its data transmission function is faulty; in this process, whether the indicator light function is faulty is identified by whether the indicator light on the HPLC module is lit; the main control module can also simulate a concentrator to send a table search instruction to the HPLC module, and the HPLC module feeds back the corresponding table search result to check whether its table search function is faulty; and the main control module can also suddenly power off the HPLC module to check whether its power outage active reporting function is faulty; through the above inspections, the inspection results of each function of the HPLC module are finally obtained.

[0091] In addition, after obtaining the test results, the determination unit in the sorting device determines which normal functions of the HPLC module are based on the test results. For example, in the test results obtained: the data interaction function has no faults, the data transmission function has no faults, the indicator light function, the table search function, the power outage active reporting function and other functions are all faulty, then it is determined that the normal functions of the HPLC module are: data interaction function and data transmission function.

[0092] In addition, after determining which functions are normal, the grading unit of the sorting device grades the HPLC modules based on the normal functions and obtains grading information; because the HPLC module includes multiple functions, the HPLC modules can be graded according to the normal functions and grading information can be obtained. For example, if the normal function of a certain HPLC module is the data interaction function, and the other functions are all faulty, then the HPLC module is graded as a recyclable module, and recyclable grading information is obtained; if the normal functions of a certain HPLC module are the data transmission function, the indicator light function, and the table search function, then the HPLC module is graded as a recyclable module, and recyclable grading information is obtained; if all functions of a certain HPLC module are faulty, then the HPLC module is graded as a discarded module, and discarded grading information is obtained; that is, if the HPLC module has normal functions, it is graded as a recyclable module, and if the HPLC module does not have normal functions, it is graded as a discarded module. After obtaining the above-mentioned grading information, the sorting unit of the sorting device performs a sorting operation on the HPLC module based on the grading information. For example, if the grading information is recyclable, the sorting device sorts the corresponding HPLC module into the recyclable category; if the grading information is discarded, the sorting device sorts the corresponding HPLC module into the discarded category.

[0093] Through the HPLC module sorting method provided in this embodiment, the sorting device detects each function of the HPLC module and obtains the detection result, and divides the HPLC module into two categories: recyclable and discarded based on the detection result, so that at least one function of the HPLC module in the recyclable category is normal, and the modules without normal function can be directly discarded, so that the HPLC has an obvious classification on whether the function is faulty, and the modules without normal function are themselves modules with no use value, which can be directly eliminated.

[0094] In actual operation, HPLC modules are mainly recycled for reuse. During use, the functional integrity and aesthetic appearance of HPLC have a greater impact on secondary users. If the sorting device is classified according to the above-mentioned sorting method, there will be incomplete functions in the recyclable HPLC modules, or there will be appearance defects that are too serious to affect normal use. On the other hand, the functional integrity and aesthetic appearance of HPLC have a direct impact on its recycling price during secondary use. Therefore, in order to further reduce the functional impact and increase its recycling value, it is classified and managed so that technicians can make corresponding recycling configurations based on actual needs.

[0095] In order to solve the above technical problems, the present invention provides a sorting method of HPLC module, such as Figure 3 As shown, the HPLC module is graded based on the normal functions to obtain the grading information, including: determining the key functions; judging whether the normal functions include all the key functions; if not including all the key functions, determining the HPLC module as a faulty module; if including all the key functions, judging whether the normal functions include non-key functions; if including non-key functions, judging whether the appearance of the HPLC meets the preset qualified conditions; if meeting the preset qualified conditions, determining the HPLC as the first grade; if not meeting the preset qualified conditions, determining the HPLC as the second grade; if not including non-key functions, determining the HPLC module as the third grade.

[0096] In a possible embodiment, the technicians in this field determine the necessary functions in the HPLC module as key functions, and the remaining functions are determined as non-key functions. For example, the technicians in this field determine the data interaction function and the data transmission function as key functions, and determine the remaining functions (such as the indicator light function, the table search function, the power failure active reporting function, etc.) as non-key functions. The grading unit of the sorting device needs to determine whether the normal function includes the data interaction function and the data transmission function. If the judgment result is that the data interaction function and the data transmission function are not included, the grading unit determines the corresponding HPLC module as a faulty module. For example, the judgment result of the grading unit is that there is only the data interaction function or only the data transmission function in the normal function, or the judgment result is that there is no data transmission function and data interaction function in the normal function. The HPLC modules corresponding to the above judgment results are all determined as faulty modules by the grading unit.

[0097] In an embodiment of the present invention, if the judgment result is that the normal function includes the data transmission function and the data interaction function, that is, the data transmission function and the data interaction function of the HPLC module are normal, then for the HPLC modules corresponding to the judgment result, the classification unit needs to further judge whether the normal functions of these modules include non-critical functions. If non-critical functions are not included, for example, a certain HPLC module is judged by the classification unit to have only the data transmission function and the data interaction function in the normal function, then this HPLC module is determined by the classification unit as a third-level module; if non-critical functions are included, for example, another certain HPLC module is judged by the classification unit to have not only the data transmission function and the data interaction function but also the indicator light function in the normal function, then it belongs to the case of including non-critical functions. In this case, the classification unit needs to further judge whether the appearance state of this HPLC module meets the preset qualified conditions. The preset qualified conditions can be the appearance conditions determined by those skilled in the art that do not affect normal use. For example, if the appearance state of a module does not affect the normal use of this module, it meets the preset qualified conditions, and the module is determined by the classification unit as a first-level module. If the appearance state of the module affects the normal use of this module, it does not meet the preset qualified conditions, and the module is determined by the classification unit as a second-level module.

[0098] Through the sorting method of HPLC modules provided in this embodiment, multiple HPLC modules are divided into first-level modules, second-level modules, third-level modules, and faulty modules according to levels from high to low by judging whether key functions are normal, whether non-key functions are normal, and whether the appearance status affects the normal use of the modules. Such classification makes it possible for the HPLC modules to have a higher level after recycling, and the higher the level, the higher the corresponding recycling economic value. In addition, technicians in this field can also clearly understand what functions the modules at each level have, and classify and manage these HPLC modules, so that when recycling and using, technicians in this field can select the corresponding type of recycled HPLC modules for secondary use according to the actual situation of the user, and can make full use of the recycled HPLC modules to reduce the operating costs of the enterprise.

[0099] In the actual operation process, for different enterprises, the HPLC module may have some non-essential functions in actual use that are also very important for the personalized needs of the enterprise. For example, the table lookup function may bring great convenience in management to some enterprises. Therefore, they are more inclined to recycle HPLC modules with normal table lookup function at a higher price. In the sorting method provided in this embodiment, the technicians in this field only regard the necessary functions of the HPLC module (such as data interaction function and data transmission function) as key functions, which will omit very important non-essential functions in the personalized needs of the enterprise, making the recycled and graded HPLC modules unable to adapt to the personalized needs of the enterprise, and the economic value of recycling is not high.

[0100] In order to solve the above technical problems, the embodiments of the present invention further perform personalized configuration on the selection of key functions. Specifically, determining the key functions includes: obtaining necessary functions; obtaining value assessment parameters of non-essential functions; judging whether the value assessment parameters meet preset premium conditions; if the preset premium conditions are met, determining the necessary functions and non-essential functions as key functions; if the preset premium conditions are not met, determining the necessary functions as key functions.

[0101] In a possible embodiment, before preparing to classify the HPLC modules, technicians in this field first determine the accurate key functions of the HPLC modules, and first obtain the necessary functions of the HPLC modules. The necessary functions are the functions that the module must have, such as the data interaction function and the data transmission function of the module. Only with these two functions can the HPLC module work normally, so the data interaction function and the data transmission function are necessary functions; among all the functions of the module, except for the data interaction function and the data transmission function, other functions (such as the indicator light function, the table search function, the power outage active reporting function, etc.) are all non-essential functions. Then, technicians in this field obtain the value assessment parameters corresponding to the non-essential functions by analyzing the historical usage data and current data of the HPLC modules. This value assessment parameter can be the frequency of use of the function, the remaining service life of the function, the number of failures of the function, etc., in order to evaluate the economic value of the use of the function and the recovery of the economic value. The selection of parameters is adjusted according to the personalized actual needs of the enterprise.

[0102] In an embodiment of the present invention, when a technician in the field obtains that the value assessment parameter of a certain HPLC module is the frequency of use of a function, the preset frequency of use is 100 times. If the frequency of use of the table search function of a module reaches 200 times, the actual frequency of use of the function far exceeds the preset frequency of use, and the preset premium condition is met, then the data interaction function, data transmission function, and table search function of the module are together determined as accurate key functions; when the value assessment parameter is the remaining service life of the function, the preset remaining service life is 0.5 years. If the remaining service life of the power outage active reporting function of a module is 1.5 years, the actual remaining service life of the function is far greater than the preset remaining service life, If the preset premium conditions are met, the data interaction function, data transmission function, and power outage active reporting function of the module are determined as accurate key functions; when the value assessment parameter is the number of function failures, the preset number of failures is 6. If the number of failures of the indicator light function of a module is 1, and the actual number of failures of the function is much smaller than the preset number of failures, the preset premium conditions are met, and the data interaction function, data transmission function, and indicator light function of the module are determined as accurate key functions; on the contrary, if the value assessment parameters of the non-essential functions of a module do not meet the preset premium conditions, the data interaction function and data transmission function of the module are determined as accurate key functions. After determining the accurate key functions according to the personalized needs of the enterprise, the sorting device uses the accurate key functions as indicators to classify the HPLC modules into new first-level modules, new second-level modules, new third-level modules, and fault modules.

[0103] Through the sorting method provided by this embodiment, the personalized needs of the enterprise are analyzed, and when sorting the HPLC modules, the key functions of the HPLC modules are more accurately determined and the HPLC modules are newly classified according to the personalized needs through the sorting device, so as to obtain HPLC modules that better meet the actual needs of the enterprise, and at the same time, a greater recycling value return can be obtained, thereby greatly improving the recycling economic value of the HPLC modules.

[0104] In actual operation, when judging whether the appearance of the HPLC module is qualified, if the appearance of the module is identified entirely by human eyes, it will cause huge manpower costs for the recycling company, which will not meet the actual needs of the company, and the identification results will also have individual deviations.

[0105] In order to solve the above technical problems, an embodiment of the present invention provides a sorting method for HPLC modules, which determines whether the appearance of HPLC meets preset qualified conditions, including: obtaining six views of the HPLC module; performing defect identification on the six views in turn to obtain defect identification results; judging whether the damaged area of ​​the HPLC module reaches a preset proportion of the total area based on the defect identification results; if the preset proportion is reached, determining that the appearance of the HPLC module does not meet the preset qualified conditions; if the preset proportion is not reached, judging whether the HPLC module has usability damage, which affects actual use; if there is usability damage, determining that the appearance of the HPLC module does not meet the preset qualified conditions; if there is no usability damage, determining that the appearance of the HPLC module meets the preset qualified conditions.

[0106] In a possible embodiment, the sorting device pre-stores the six views (up, down, left, right, front, and back views) of the current HPLC module before it is used or when the module just leaves the factory. Then, in the subsequent sorting process, the sorting device collects the current six views of the module. Then, the sorting device sequentially identifies the defect type between the original six views and the current six views. The defect type is, for example, damage in the blank. When it is identified that the current six views have damage in the blank, the damage area is further obtained. When the damage area reaches 20% of the total area, the appearance state of the module does not meet the preset qualified conditions. When the damage area does not reach 20% of the total area, the sorting device continues to judge the module. Whether the module has any usability damage, which may be damage that affects the actual use of the module, such as text obstruction or unclear text. For example, in one embodiment, the display screen of the module is partially obstructed or damaged, resulting in the text being obstructed or unable to be displayed normally. The sorting device determines that the appearance of the module does not meet the preset qualification conditions. When there is no text obstruction in the module, the sorting device determines that the appearance of the module meets the qualification conditions, that is, the appearance of the module is qualified. Finally, the sorting device performs the operation of grading the module into a first-level module or a new first-level module based on the result that the appearance is qualified.

[0107] Through the sorting method provided in this embodiment, image recognition replaces manual recognition, which greatly improves the recognition efficiency and greatly reduces the recognition cost. At the same time, it can also effectively avoid the individual deviation caused by manual recognition and improve the accuracy of appearance status recognition.

[0108] In actual application, due to the differences in product quality of HPLC modules from different manufacturers and the differences in product quality of different batches from the same manufacturer, there may be HPLC modules with low recovery rates. For such modules, their recycling costs are close to or even exceed the social and economic value they generate, so they are not meaningful for recycling, which reduces the company's recycling efficiency and wastes the company's recycling resources.

[0109] In order to solve the above technical problems, an embodiment of the present invention provides a sorting method for HPLC modules, which also includes: obtaining the detection quantity of the HPLC module and the recovery quantity of each classification; determining the detection cost based on the detection quantity; determining the recovery economic value of the HPLC module based on the recovery quantity of each classification; judging whether the HPLC module has recovery value based on the detection cost and the recovery economic value, and generating a judgment result; obtaining the hardware information of the HPLC module, and feeding back the judgment result and the hardware information.

[0110] In a possible embodiment, for the HPLC modules recovered from the A1 batch of manufacturer A, the sorting device obtains the total number of HPLC modules detected in the batch, for example, the total number is 5000, and also obtains the number of recovered modules corresponding to each level after the sorting is completed, for example, the first classification module is 300, the second classification module is 1000, and the third classification module is 1200. The recovery cost of each module is calculated according to the calculation rules pre-set by those skilled in the art based on labor costs, storage costs, transportation costs, and other costs (electricity, factory rent, etc.). For example, the recycling freight is 1000 yuan, and the recycling transportation fee of each module is 0.2 yuan. The manpower required to complete the detection of all modules is 1000 yuan. The labor cost is 10,000 yuan, that is, the labor cost of recycling and testing each module is 2 yuan... After calculation, the recycling cost of each module is 6 yuan, and the total recycling cost of this batch is 30,000 yuan; further, the economic value that can be generated by the first-level module is pre-set to 20 yuan, the second-level module is 10 yuan, and the third-level module is 5 yuan, then the total economic value generated by the recycling modules in this batch of modules is 22,000, and the total economic value generated by the recycling is lower than the total recycling cost, that is, this recycling has no recycling value. At this time, the sorting device obtains the hardware information of the batch, such as manufacturer information, batch information, etc., and the sorting device feeds back the hardware information corresponding to the batch and the recycling value result to the central control unit.

[0111] The central control unit notifies the management personnel of the above information in the form of text prompts, pop-up prompts, SMS notifications, etc. During the subsequent recycling process of the HPLC modules, the management personnel directly identify the HPLC modules of this batch from this manufacturer as scrapped modules, and no longer transport them back to the warehouse for sorting operations, thereby effectively avoiding the waste of recycled resources, effectively improving the recycling effectiveness and efficiency of HPLC, and improving the operating benefits of the enterprise.

[0112] Through the sorting method provided in this embodiment, after the sorting device completes the sorting, the recovery economic value of the HPLC modules of this batch can be calculated, and the recovery rate of each level of modules in the batch of modules can also be calculated. By comparing the recovery economic value with the total recovery cost, it can be concluded whether the recovery of the modules of this batch has recovery value. The enterprise can obtain the hardware information of this batch as a reference to avoid some manufacturers with production quality deviations in the future procurement of HPLC modules. At the same time, if the modules of the same batch have repeatedly had low recovery rates or no recovery value, the remaining unsorted modules of the batch can be directly considered for scrapping, thereby saving the enterprise's recycling resources and improving recycling efficiency.
