Detailed Description

The present application will be described in further detail with reference to examples and drawings, but the embodiments of the present application are not limited thereto.

A consumable intelligent management method based on gravity sensing, as shown in figure 1, comprises the following steps:

s100, establishing and storing user identity information and corresponding borrowing list information in an associated mode;

s200, corresponding storage space 6 and recovery space 7 are allocated for various consumable materials, and starting permission is set;

s300, acquiring consumable information to be acquired, which is input by a user, confirming the user' S receiving authority according to the current borrowing list information, unlocking the corresponding storage space 6 according to the confirmation result, updating the borrowing list information, or maintaining the locking state of the storage space 6;

s400, acquiring consumable information to be returned, which is input by a user, confirming the user returning authority according to the current borrowing list information, unlocking the corresponding recovery space 7 according to the confirmation result, updating the borrowing list information, or maintaining the locking state of the recovery space 7;

wherein, each storage space 6 and recovery space 7 is provided with a weight detection device for detecting the real-time storage state of the consumable part, and the borrowing list information is updated based on the weight detection signals.

It should be noted that the order of the steps described above may be alternated in practice, as the order between S100 and S200 is not strictly limited and is only a preferred embodiment in the present description.

In detail, referring to fig. 2, in step S100, user identity information and corresponding borrowed list information thereof are established and stored in association, where the user identity information includes a user name and related verification information thereof, such as ID information registered when the user logs into the system. The borrowing list information comprises consumable category information, consumable quantity information, acquisition time information and the like which are borrowed by the user. After the user creates ID information in the system, the system automatically binds a borrowing list information for the user and associates and stores the borrowing list information with the user identity information.

The related verification information comprises one or more of RFID verification recognition, fingerprint verification recognition and password verification recognition. In practical application, other biometric identification methods can be used to verify the user identity information, such as iris identification. Correspondingly, the identity verification information of the user is stored in the management system in advance, and the identity verification information, such as fingerprint information, is usually input when the user registers.

In the step S200, in order to facilitate the management of various types of consumables, the corresponding storage space 6 and recovery space 7 are allocated for various types of consumables, and the storage space 6 and recovery space 7 are specifically configured in practice as drawer-shaped storage grids in the consumable cabinet body 1, and the whole storage grids adopt a grid-shaped layout mode. Each storage grid department all is provided with the cabinet door and the locking device that are used for locking storage grid. In order to determine the storage state of the consumable in each storage grid, a weight detection device for weighing is provided at the bottom of each storage grid, preferably by a high-precision pressure sensor, and outputs a weight detection signal when the weight in the storage space 6 or the recovery space 7 changes. In order to facilitate the management of consumable materials, the disorder of the receiving and returning operations of the consumable materials is avoided, and the locking devices of the storage grids are provided with starting authorities.

In detail, the enabling rights of the storage space 6 and the recovery space 7 include user login rights and consumable receiving rights (including consumable returning rights). Correspondingly, in the process of picking up or returning the consumable, user login permission verification and consumable picking-up permission verification are required. Checking user login permission: collecting and identifying user identity information, and outputting first authority information; and (5) checking consumable receiving permission: retrieving borrowing list information corresponding to a user based on the acquired user identity information, judging the operation authority of the consumable to be retrieved or returned by the user based on the list information, and outputting second authority information; comprehensive rights management: and receiving the first authority information and the second authority information, analyzing and judging whether the storage space 6 or the recovery space 7 is started.

Above-mentioned technical scheme, the user wants to obtain the consumptive material, not only needs to verify self identity information, still needs to verify borrow list information under the user name, can avoid other people borrow the nominal of user to get or return the consumptive material from this, cause management confusion, can also standardize the operation of getting and returning of consumptive material, only can get new consumptive material after the consumptive material that the user returned the earlier stage and get, convenient management also avoids the consumptive material to be abused and privately occupy.

Referring to fig. 2, in step S300, when the user needs to retrieve new consumables, the system obtains the consumable information to be retrieved by the user and compares the consumable information with the borrowing list information, if the borrowing list information shows that the user has the consumable of the same category but has not returned, the system will not give the user new consumable retrieval authority, and only after the user returns the consumable of the same category previously retrieved, the system will only control the relevant storage grid to be opened. In the same way, in step S400, the authority of returning the consumable by the user is also confirmed, and only when the unreturned consumable information is stored in the borrowing list information associated with the user identity information, the system gives the authority of returning the consumable to the user, thereby avoiding confusion of consumable management.

In the above method steps, the system only records and manages the receiving of the consumable, and does not analyze the actual use condition of the consumable, so as to fully utilize the configuration of the system to achieve the effect of realizing the complex function by using the simple hardware configuration, in the embodiment of the present application, as shown in fig. 3, the method further includes:

a100, collecting and storing initial weight values of various consumable materials and recycling weight values after use;

a200, calculating and generating a recovery weight value according to the to-be-recovered consumable information input by the user and the recovery weight value corresponding to the consumable;

a300, acquiring an actual weight value of the consumable to be returned from the user to the recovery space 7, and calculating a difference value between the actual weight value and the receivable weight value;

a310, if the difference value is in the set range, updating borrowing list information according to consumable information to be returned, which is input by a user;

and A311, if the difference exceeds the set range, outputting alarm information and/or outputting alarm information and marking and updating the alarm information into the borrowing list information.

Because each class consumptive material can change when comparing when getting up in the later stage of use self weight, for example the emery wheel can become light before the use after the weight to the weight that becomes light closely correlates with the circumstances of emery wheel self use, and the emery wheel after the abundant use can be in a relatively fixed numerical value, above-mentioned recovery weight value. Through monitoring the change of the weight, the type of the consumable can be judged and identified during recycling, and the service condition of the consumable can be recorded so as to facilitate later analysis. Therefore, through the technical scheme, the use condition of each consumable can be recorded, if the use rate of the consumable meets the requirement, the returned consumable can be checked, when the returned material is inconsistent with the previously borrowed consumable, the system sends out alarm information, the consumable category return error caused by carelessness of a user is avoided, and the consumable management and the consumable use condition tracking in the later period are also facilitated. The alarm information can be transmitted to a user through a voice player on the field consumable cabinet so as to remind the user to confirm whether returned consumables are consistent with the consumables recorded in the borrowing list.

Based on the inventive concept, the method in the embodiment of the present application further comprises:

a320, dividing the difference between the weight value to be received and the actual weight value into a plurality of difference intervals and assigning weight values to the difference intervals;

a321, calculating a difference value between the receivable weight value and the actual weight value, and endowing the consumable recovery action with a corresponding weight value according to a difference value interval where the difference value is located;

a322, storing the weight value and the user identity information in an associated mode, and calculating the sum of the weight values associated with the user identity information;

a323, if the weight value corresponding to the user identity information exceeds the set value, outputting alarm information.

According to the scheme, the use habit of each user on various consumables can be known by means of the alarm information, the supervision effect is realized on the irregular retrieval and return operation of the user, and the user identity information is given a weight value by each retrieval and return operation, so that a system administrator can call the data of each user at any time to analyze the use condition of the consumables, the consumables and the users can be managed in a refined mode, and the use rate of the consumables is improved.

Because only the weight detection device is adopted in the whole system to confirm the retrieval or return operation of the consumable, in order to reduce the probability that the user confuses the consumable class and returns the consumable by mistake when returning the consumable, and improve the identification precision of the consumable class, in the embodiment of the application, after the information of the consumable to be retrieved, which is input by the user, is acquired, as shown in fig. 4, the method further comprises:

b100, analyzing the consumable information to be returned input by the user, and obtaining the number of consumable items of each type;

b200, if the number of consumable materials in the same category exceeds 1, sequentially acquiring the actual weight value of the consumable materials to be returned in the recovery space 7 returned by the user;

b300, successively calculating the difference value between the actual weight value and the receivable weight value of the consumable material returned to the recycling space 7;

b310, if the difference values are in the set range, updating the borrowing list information;

and B320, if the difference value exceeds the set range at least once, updating the borrowing list information and storing an alarm message in an associated mode.

The scheme can avoid statistical errors caused by the fact that a plurality of consumables of the same type are placed in the recovery space 7 at one time by a user, and reduces the probability of confusion when consumable materials of different weights of different types return. In step B200, the system may take the weight change collected by the weight detecting device in the storage grid as a weighing result, and take the difference value before and after each change as the weight value of the consumable returned at the present time, so that the weight of each returned consumable can be counted rapidly.

In order to reduce the probability of confusion during consumable returning, and output an alarm when the weight of the consumable to be returned is abnormal, the consumable receiving and returning process is conveniently traced in the later period, and in the embodiment of the application, the method further comprises the following steps of:

c100, judging whether the number of consumable materials in the same category is a plurality of consumable materials according to the acquired consumable material information to be returned by the user;

if the number of the consumable supplies in the same category to be returned is a plurality of consumable supplies, dividing the consumable supplies into at least two groups according to a set algorithm, dividing the number of consumable supplies required to be returned in each group, and outputting and displaying; if the number of consumable supplies in the same category is not more than 2, the recycling operation is performed according to the step B200.

C300, calculating and generating the recovery weight value of each group of consumable parts to be recovered based on the recovery weight value of each type of consumable parts, and comparing the recovery weight value with the obtained actual weight value of the consumable parts to be recovered in the recovery space 7 by the user to obtain a difference value;

c310, if the difference values are all in the set range, updating the borrowing list information;

and C320, if the difference value exceeds the set range, updating the borrowing list information and storing an alarm message in an associated mode.

In the scheme, the same type of consumable to be returned is divided into a plurality of parts by the system, each part of consumable to be returned forms a special weight, if the number of consumable to be returned is 6, the recycling weight value of a single consumable is 0.5Kg, the allowable error range is 0.02Kg, the 6 consumable to be returned can be divided into three groups, namely a first group of 0.5Kg, a second group of 2 1.0Kg and a third group of 3 1.5Kg, a complete or other set value is formed, the weight value is not easy to be tampered or obtained by using other types of spliced consumable, and therefore, once the actual weight value of the consumable to be returned exceeds the set range, the fact that the consumable to be returned is inconsistent with the consumable selected to be returned by a user can be judged, an alarm is timely output, and the management of the consumable is convenient.

Because different technologies and procedures in the production process can correspondingly use different types of consumables, in order to monitor the overall use condition of the consumables, in the embodiment of the application, the method further comprises the following steps:

d100, calculating and storing theoretical association relations among consumable consumption of each category based on a product production process;

d200, acquiring borrowing list information of each user, summarizing and analyzing the borrowing list information, generating consumption of consumables of each class and actual association relation and storing the consumption;

and D300, selecting standard consumable materials from the consumable materials of each class, taking the standard consumable materials as a reference, identifying the consumable material class with abnormal consumption based on a setting algorithm, and retrieving and outputting associated borrowing list information.

In the step D100, the consumption relationships between consumables are stored in association, for example, when grinding and polishing are performed on the same product, the consumption of grinding wheels or sand papers with different meshes has a positive correlation, that is, when the consumption of consumables in the previous process increases, the consumption of consumables corresponding to the subsequent process should correspondingly increase, and the increased value can be calculated theoretically. Therefore, after collecting and analyzing the borrowing list information of each user, whether the consumption of the consumable is abnormal or not can be judged, if the consumption is abnormal, the associated borrowing list information is timely output, so that a manager can determine the reason of the abnormal consumption of the consumable, and the targeted improvement of the production process or the consumable management method is facilitated.

In the embodiment of the application, the alarm information comprises consumable return time data, consumable category data and consumable weight data during return. The data can track and record irregular picking up or returning of the consumable or abnormal use of the consumable, and is helpful for improving the use and management method of the consumable in the later period.

Compared with the consumable management method in the prior art, the method fully utilizes the weight detection device in the storage space 6 to monitor the access state of the consumable, and simultaneously enables the user to get and restore the consumable to be completely recorded based on the borrowing list information, and only when the consumable which is taken before is restored, new consumable can be taken, so that the consumable is convenient for fine management, the consumable is prevented from being abused, meanwhile, the constitution of the whole system is simplified, and the system construction and operation and maintenance cost is reduced. And, through the change to weight before and after the consumptive material uses, trace the evaluation to the service behavior of consumptive material, help the use management of consumptive material, because the weight difference is different around all kinds of consumptive materials use, therefore can realize the class discernment when the consumptive material returns by weight difference, take place to confuse when avoiding returning the consumptive material, promote the accuracy of consumptive material management.

In order to realize the above-mentioned consumable intelligent management method based on gravity sensing, the application also provides a consumable intelligent management system based on gravity sensing, as shown in fig. 6 and 7, mainly comprising a cabinet body 1, a weight detection module 2, a first authority verification module 3, a second authority verification module 4 and a control module 5.

The locking device is in control connection with the control module 5.

The weight detection module 2 is disposed in each of the storage space 6 and the recovery space 7, and is configured to detect a consumable storage state and a weight change in each of the storage space 6 and the recovery space 7, and output a weight detection signal. In practical application, the weight detecting module 2 includes pressure sensors disposed in each storage grid, i.e. the storage or recovery space 7, and the pressure sensors can detect and output the weight of the consumable after the consumable is placed in the storage grid.

The first authority checking module 3 is configured to collect and identify user identity information, and output first authority information. The user identity information includes, but is not limited to, fingerprint information, password information, RFID data information. The fingerprint acquisition identifier, the password input identifier and the RFID identifier on site can acquire and identify the identity information of the user, and the first authority information is output after the identification is successful.

The second permission checking module 4 is configured to obtain user identity information and retrieve borrowing list information corresponding to the user, and generate second permission information for reflecting the current retrievable and returned consumables of the user. In practical application, the user can only retrieve the new consumable of the same category after returning the corresponding consumable, the second permission checking module 4 is actually a data comparison algorithm, receives and analyzes the consumable information to be retrieved or returned input by the user, and then compares the consumable information with the borrowed list information in the memory to output the second permission information.

The control module 5 is configured to be in control connection with a plurality of locking devices, receive the first authority information and the second authority information, analyze the first authority information and the second authority information, determine whether to enable the storage space 6 or the recovery space 7, and output a control signal to control the locking state of each locking device.
