Description

Technical Field

[0001] The present invention belongs to the technical field of quality control, and in particular relates to a smart furniture quality management method based on MEMS sensors. Background Art

[0002] In order to solve the quality inspection and management problems of furniture, the invention patent CN202310002552.5 "A quality management method, system, computer equipment and storage medium" actively replenishes or repairs panels with quality problems during the cleaning process, and records them through a replacement application form, which facilitates the statistics and tracing of the replacement applications that have occurred. However, there are the following technical problems:

[0003] The existing technical solutions lack the ability to determine the installation quality of different furniture based on sensors, etc., and to generate differentiated quality control measures based on the installation quality of different furniture. The existing quality control method often generates quality control measures through quality inspection data within the factory, but the specific quality problems of furniture can often only be truly displayed and processed in actual use. The deformation under different pressures and the stable state of the connecting locks will have a certain degree of difference. Therefore, if quality control measures cannot be generated through real quality inspection data from sensors, the production quality and installation quality of the furniture cannot be guaranteed.

[0004] In response to the above technical problems, the present invention provides a smart furniture quality management method based on MEMS sensors. Summary of the invention

[0005] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0006] According to one aspect of the present invention, a smart furniture quality management method based on MEMS sensors is provided.

[0007] A smart furniture quality management method based on MEMS sensors, characterized by comprising:

[0008] S1: installing a MEMS sensor to a connection lock position and a support frame of the assembled furniture, and determining connection pressures of different connection lock positions and support pressures of the support frame based on the MEMS sensor;

[0009] S2: determining the rated support pressure of the assembled furniture according to the model of the assembled furniture, and evaluating the problem amount of the connection lock position of the assembled furniture and determining the problem connection lock position based on the connection pressure of the connection lock position of the assembled furniture under different support pressures and the rated support pressure of the assembled furniture;

[0010] S3 determines the problem evaluation amounts of different problematic connection lock positions of different assembled furniture based on different problematic connection lock positions, and determines the comprehensive problem evaluation amounts of different problematic connection lock positions in combination with the number of assembled furniture with problems at the different problematic connection lock positions and the time when the problems occurred;

[0011] S4 performs furniture problem assessment quantities for different assembled furniture and determines problematic assembled furniture according to the number of problematic connecting lock positions and the problem assessment quantities of the connecting lock positions, determines the comprehensive quality assessment value of the assembled furniture in combination with the comprehensive problem assessment quantities of the problematic connecting lock positions, and outputs quality control measures for the assembled furniture based on the comprehensive quality assessment value.

[0012] The beneficial effects of the present invention are:

[0013] 1. By evaluating the problem quantity of the connection lock positions of assembled furniture and determining the positions of problematic connection locks, it is possible to screen out problematic connection locks according to the actual pressure conditions of the connection lock positions under different supporting pressures, thus avoiding the technical problem of low quality control accuracy caused by relying solely on the factory's quality inspection measures.

[0014] 2. The comprehensive problem assessment quantity of different problematic connection and lock positions is determined by combining the number of assembled furniture with problems at the problematic connection and lock positions and the time when the problem occurred. This not only takes into account the problem situation of a single problematic connection and lock position of a certain assembled furniture, but also further combines the number of assembled furniture with similar problematic connection and lock positions within a certain area, thereby achieving an accurate assessment of the severity of the problem at the problematic connection and lock position.

[0015] 3. The comprehensive quality assessment value of assembled furniture is determined by combining the comprehensive problem assessment of problematic assembled furniture and problematic connection lock positions. This enables the quality of assembled furniture to be assessed from two perspectives, including the number of problematic assembled furniture and the severity of the problems, as well as the severity of the problems with the connection locks. This also lays the foundation for further targeted quality control of assembled furniture.

[0016] A further technical solution is that the MEMS sensor includes one or more of a silicon piezoresistive pressure sensor and a capacitive pressure sensor.

[0017] A further technical solution is that the number of MEMS sensors arranged at the support frame is determined according to the area of ​​the support frame. Specifically, the larger the area of ​​the support frame is, the more MEMS sensors are arranged.

[0018] A further technical solution is that the problematic connection lock position is determined based on a problem evaluation amount of the connection lock position of the assembled furniture. Specifically, when the problem evaluation amount of the connection lock position of the assembled furniture is greater than a preset problem threshold, the connection lock position is determined to be a problematic connection lock position.

[0019] In a second aspect, the present invention provides a smart furniture quality management terminal based on a MEMS sensor, which adopts the above-mentioned smart furniture quality management method based on a MEMS sensor, and is characterized in that it specifically includes:

[0020] Pressure acquisition module, problem determination module, lock evaluation module, quality management module;

[0021] The pressure acquisition module is responsible for installing the MEMS sensor at the connection lock position and the support frame of the assembled furniture, and determining the connection pressure of different connection lock positions and the support pressure at the support frame based on the MEMS sensor;

[0022] The problem determination module is responsible for determining the rated support pressure of the assembled furniture according to the model of the assembled furniture, and performing a problem evaluation amount of the connection lock position of the assembled furniture and determining the problematic connection lock position based on the connection pressure of the connection lock position of the assembled furniture under different support pressures and the rated support pressure of the assembled furniture;

[0023] The lock evaluation module is responsible for determining the problem evaluation amounts of different problematic connection lock positions of different assembled furniture based on different problematic connection lock positions, and determining the comprehensive problem evaluation amounts of different problematic connection lock positions in combination with the number of assembled furniture with problems at the different problematic connection lock positions and the time when the problems occurred;

[0024] The quality management module is responsible for determining the furniture problem evaluation amount of different assembled furniture and the problematic assembled furniture according to the number of problematic connection lock positions of different assembled furniture and the problem evaluation amount of the connection lock positions, and determining the comprehensive quality evaluation value of the assembled furniture in combination with the comprehensive problem evaluation amount of the problematic connection lock positions, and outputting the quality control measures of the assembled furniture according to the comprehensive quality evaluation value.

[0025] On the other hand, the present invention provides a computer system, comprising: a memory and a processor connected in communication, and a computer program stored in the memory and capable of running on the processor, characterized in that: when the processor runs the computer program, it executes the above-mentioned smart furniture quality management method based on MEMS sensors.

[0032] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0033] The applicant has found that the quality control of existing smart furniture is often determined based on the test results in the factory, but often the problems of the lock connection of smart furniture are only discovered after a certain period of use. Therefore, if the quality problems cannot be discovered according to the actual usage of different users, accurate and targeted quality control cannot be achieved. The installation of sensors referred to in this application must be done with the consent and knowledge of the user.

[0034] Example 1

[0035] To solve the above problems, according to one aspect of the present invention, Figure 1 As shown, a smart furniture quality management method based on MEMS sensors is provided, which is characterized by specifically including:

[0036] S1: installing a MEMS sensor to a connection lock position and a support frame of the assembled furniture, and determining connection pressures of different connection lock positions and support pressures of the support frame based on the MEMS sensor;

[0037] Specifically, the MEMS sensor includes one or more of a silicon piezoresistive pressure sensor and a capacitive pressure sensor.

[0038] It can be understood that the number of MEMS sensors arranged on the support frame is determined according to the area of ​​the support frame. Specifically, the larger the area of ​​the support frame is, the more MEMS sensors are arranged.

[0039] S2: determining the rated support pressure of the assembled furniture according to the model of the assembled furniture, and evaluating the problem amount of the connection lock position of the assembled furniture and determining the problem connection lock position based on the connection pressure of the connection lock position of the assembled furniture under different support pressures and the rated support pressure of the assembled furniture;

[0040] In one possible embodiment, Figure 2 As shown, the method for determining the problem evaluation amount of the connection lock position of the assembled furniture in the above step S2 is:

[0041] S11 determines the problematic connection pressure of the connection lock position by the connection pressure of the connection lock position of the assembled furniture under different supporting pressures, and judges whether there is problematic connection pressure of the connection lock position under different supporting pressures. If yes, proceed to the next step; if not, determine the problematic evaluation amount of the connection lock position of the assembled furniture by the deviation amount between the connection pressure of the assembled furniture under the rated supporting pressure and the boundary pressure within the preset pressure range;

[0042] S12: using the support pressure corresponding to the problematic connection pressure at the connection lock position as the problematic support pressure, and determining whether the connection lock position is abnormal according to the connection pressure threshold under the problematic support pressure and the deviation amount of the problematic connection pressure, if yes, proceeding to step S14, if no, proceeding to step S13;

[0043] S13: taking the support pressure corresponding to the problematic connection pressure at the connection lock position as the problematic support pressure, and determining the problematic support pressure deviation amount according to the problematic support pressure and the deviation amount of the rated support pressure, and determining whether the connection lock position is abnormal based on the maximum value of the problematic support pressure deviation amount, if yes, proceeding to step S14, if no, determining the problematic evaluation amount of the connection lock position of the assembled furniture according to the maximum value of the problematic support pressure deviation amount;

[0044] S14 determines the severity of the problem under different problem support pressures according to the problem connection pressure under the problem support pressure, and determines the corrected problem severity under different problem support pressures in combination with the problem support pressure and the deviation of the rated support pressure, and determines the problem evaluation amount of the connection lock position of the assembled furniture through the corrected problem severity under different problem support pressures, the maximum value of the problem support pressure deviation and the number of problem support pressures.

[0045] It can be understood that the problematic connection lock position is determined based on the problem evaluation amount of the connection lock position of the assembled furniture. Specifically, when the problem evaluation amount of the connection lock position of the assembled furniture is greater than a preset problem threshold, the connection lock position is determined to be a problematic connection lock position.

[0046] In this embodiment, by evaluating the problem quantity of the connection lock positions of assembled furniture and determining the problematic connection lock positions, it is possible to screen out the problematic connection locks according to the actual pressure conditions of the connection lock positions under different supporting pressures, thereby avoiding the original technical problem of low quality control accuracy caused by relying solely on factory quality inspection measures.

[0047] S3 determines the problem evaluation amounts of different problematic connection lock positions of different assembled furniture based on different problematic connection lock positions, and determines the comprehensive problem evaluation amounts of different problematic connection lock positions in combination with the number of assembled furniture with problems at the different problematic connection lock positions and the time when the problems occurred;

[0048] In one possible embodiment, the method for determining the comprehensive problem evaluation amount of the problematic connection lock position in step S3 is:

[0049] S21 determines the number of assembled furniture having problems with the problematic connection lock position based on the problematic connection lock position, and determines whether there is a problem with the connection state of the problematic connection lock position in combination with the total number of assembled furniture, if yes, proceeds to step S23, if no, proceeds to step S22;

[0050] S22 regards the assembled furniture with the problem connection lock position as the corresponding problem assembled furniture, and determines whether there is a problem with the connection state of the problem connection lock position according to the maximum value of the problem evaluation amount of the problem connection lock position of the corresponding problem assembled furniture. If yes, proceed to step S23; if not, determine the comprehensive problem evaluation amount of the problem connection lock position based on the proportion of the corresponding problem assembled furniture in the number of assembled furniture;

[0051] S23: determining a problem evaluation amount of a problem connection lock position of the corresponding problematic assembled furniture based on the corresponding problematic assembled furniture, determining a problem correction amount of different corresponding problematic assembled furniture in combination with different problem occurrence times of the corresponding problematic assembled furniture, and determining the seriously problematic assembled furniture and the generally problematic assembled furniture based on the problem correction amount;

[0052] S24 determines the comprehensive problem correction amount of the problematic connection locking position by combining the number of assembled furniture with serious problems and the problem correction amount of the problematic connection locking position, the number of assembled furniture with general problems and the problem correction amount of the problematic connection locking position, and determines the comprehensive problem evaluation amount of the problematic connection locking position in combination with the total number of assembled furniture and the problem evaluation amount of the problematic connection locking position.

[0053] Specifically, determining whether there is a problem with the connection state of the problematic connection lock position according to the maximum value of the problem evaluation amount of the problematic connection lock position of the corresponding problematic assembled furniture specifically includes:

[0054] When the maximum value of the problem evaluation amount of the problematic connection lock position corresponding to the problematic assembled furniture is not within the preset interval, it is determined that there is a problem with the connection state of the problematic connection lock position.

[0055] In another possible embodiment, the method for determining the comprehensive problem evaluation amount of the problematic connection lock position in the above step S3 is:

[0056] The assembled furniture with problems at the problematic connection lock position is taken as the corresponding problematic assembled furniture, and the problem assessment amount of the problematic connection lock position of the corresponding problematic assembled furniture is determined based on the corresponding problematic assembled furniture, and different problem correction amounts of the corresponding problematic assembled furniture are determined in combination with different problem occurrence times of the corresponding problematic assembled furniture, and the assembled furniture with serious problems and the assembled furniture with general problems are determined based on the problem correction amounts;

[0057] When it is determined based on the total number of assembled furniture that the number of the seriously problematic assembled furniture and the number of the generally problematic assembled furniture meet the requirements:

[0058] Determine the comprehensive problem evaluation amount of the problematic connection lock position by using the proportion of the number of the seriously problematic assembled furniture and the proportion of the number of the generally problematic assembled furniture;

[0059] When any one of the quantity of the assembled furniture with serious problems and the quantity of the assembled furniture with general problems determined based on the total quantity of the assembled furniture fails to meet the requirement:

[0060] Determine the comprehensive problem correction amount of the problematic connection lock position by using the number of the seriously problematic assembled furniture and the problem correction amount of the problematic connection lock position, and the number of the generally problematic assembled furniture and the problem correction amount of the problematic connection lock position;

[0061] The problem correction amounts of the problematic connection locking positions of different assembled furniture are determined based on the problem occurrence times and the problem evaluation amounts of the problematic connection locking positions, and the basic problem evaluation amounts of the problematic connection locking positions are determined in combination with the total number of the assembled furniture. The comprehensive problem evaluation amount is determined through the comprehensive problem correction amount of the problematic connection locking positions and the basic problem evaluation amount of the problematic connection locking positions.

[0062] In this embodiment, the comprehensive problem evaluation amount of different problematic connection locking positions is determined by combining the number of assembled furniture with problems at the problematic connection locking positions and the time when the problems occurred. This not only takes into account the problem situation of a single problematic connection locking position of a certain assembled furniture, but also further combines the number of assembled furniture with similar problematic connection locking positions within a certain area, thereby achieving an accurate assessment of the severity of the problem at the problematic connection locking position.

[0063] S4 performs furniture problem assessment quantities for different assembled furniture and determines problematic assembled furniture according to the number of problematic connecting lock positions and the problem assessment quantities of the connecting lock positions, determines the comprehensive quality assessment value of the assembled furniture in combination with the comprehensive problem assessment quantities of the problematic connecting lock positions, and outputs quality control measures for the assembled furniture based on the comprehensive quality assessment value.

[0064] In one possible embodiment, the method for determining the furniture problem evaluation amount of the assembled furniture in the above step S4 is:

[0065] S31 determines whether the assembled furniture is problematic assembled furniture based on the number of problematic interlocking lock positions of the assembled furniture. If so, determines that the assembled furniture is problematic assembled furniture, and determines the furniture problem assessment amount of the assembled furniture according to the number of problematic interlocking lock positions of the assembled furniture. If not, proceeds to the next step.

[0066] S32 obtains the problem evaluation amount of the connection lock position of the assembled furniture, and determines whether the maximum value of the problem evaluation amount of the connection lock position of the assembled furniture meets the requirements. If so, it is determined that the assembled furniture does not belong to the problem assembled furniture, and the furniture problem evaluation amount of the assembled furniture is determined according to the maximum value of the problem evaluation amount of the connection lock position of the assembled furniture. If not, proceed to the next step;

[0067] S33 determines the number of problematic connection lock positions of the assembled furniture and the ratio of the interlocking lock positions of the assembled furniture through the problematic connection lock positions of the assembled furniture, and determines the problem quantity of the problematic connection locks of the assembled furniture in combination with the number and the average value of the problem evaluation quantities of the problematic connection lock positions of the assembled furniture, and judges whether the problem quantity of the problematic connection locks of the assembled furniture meets the requirements. If so, it is determined that the assembled furniture does not belong to problematic assembled furniture, and the furniture problem evaluation quantity of the assembled furniture is determined according to the problem quantity of the problematic connection locks of the assembled furniture. If not, proceed to the next step;

[0068] S34 obtains the average value of the problem evaluation amount of the connection lock positions of the assembled furniture and the number of connection lock positions whose problem evaluation amount is greater than the problem limit value, and determines the furniture problem evaluation amount of the assembled furniture in combination with the problem amount of the problematic connection locks of the assembled furniture.

[0069] Specifically, the method for determining the furniture problem evaluation amount of the assembled furniture in the above step S3 is:

[0070] The number of problematic connection lock positions of the assembled furniture and the ratio of the interlocking lock positions of the assembled furniture are determined through the problematic connection lock positions of the assembled furniture, and the number of problem evaluation quantities of the problematic connection lock positions of the assembled furniture and the average value of the problem evaluation quantities are combined to determine the problem quantity of the problematic connection locks of the assembled furniture;

[0071] When the problem quantity of the connection lock of the assembled furniture meets the requirements:

[0072] Obtain the number of connection lock positions where the problem evaluation amount of the assembled furniture is greater than the problem limit value, and when the number of connection lock positions where the problem evaluation amount of the assembled furniture is greater than the problem limit value is not greater than the preset number of locks:

[0073] Using the problematic connection and lock problem quantity of the assembled furniture as the furniture problem evaluation quantity of the assembled furniture;

[0074] When the problem evaluation quantity of assembling furniture is greater than the problem limit value, the number of connection lock positions is greater than the preset number of locks, or the problem quantity of connection locks of assembling furniture does not meet the requirements:

[0075] The connection lock positions of the assembled furniture whose problem evaluation amount is greater than the problem limit value are used as screening lock positions, and the screening furniture problem evaluation amount of the assembled furniture is determined according to the number of the screening lock positions, the weights of the problem evaluation amounts, and the average value of the problem evaluation amounts of the screening lock positions;

[0076] The average value of the problem evaluation amount of the connection lock positions of the assembled furniture and the number of connection lock positions are obtained, and the furniture problem evaluation amount of the assembled furniture is determined in combination with the screening furniture problem evaluation amount of the assembled furniture and the problem amount of the problematic connection locks of the assembled furniture.

[0077] In one possible embodiment, the method for determining the comprehensive quality evaluation value of the assembled furniture in step S4 is:

[0078] S41 determines the basic quality assessment value of the assembled furniture by setting the average value of the furniture problem assessment amounts of all assembled furniture in the area, the proportion of the problematic assembled furniture, and the number of furniture problem assessment amounts of the problematic assembled furniture;

[0079] S42 determines the problem connection lock positions whose comprehensive problem evaluation amount does not meet the requirement by setting the comprehensive problem evaluation amount of all the problem connection lock positions of the assembled furniture in the area, and uses the problem connection lock positions whose comprehensive problem evaluation amount does not meet the requirement as the screening problem lock positions, and judges whether the number of the screening problem lock positions meets the requirement, if yes, proceeds to the next step, if not, proceeds to step S44;

[0080] S43 determines the maximum value of the comprehensive problem evaluation amount of the screening problem lock position based on the screening problem lock position, and determines the screening problem lock evaluation amount of the assembled furniture in combination with the number of screening problem lock positions and the average value of the comprehensive problem evaluation amount, and judges whether the screening problem lock evaluation amount meets the requirements. If so, the basic quality evaluation value of the assembled furniture is used as the comprehensive quality evaluation value of the assembled furniture. If not, proceed to step S44;

[0081] S44 obtains the number of problematic connection lock positions and a comprehensive problem evaluation amount of the assembled furniture, determines the quality correction amount in combination with the screening problem lock evaluation amount of the assembled furniture, and determines the comprehensive quality evaluation value of the assembled furniture in combination with the basic quality evaluation value of the assembled furniture.

[0082] In this embodiment, the comprehensive quality assessment value of the assembled furniture is determined by combining the comprehensive problem assessment amounts of the problematic assembled furniture and the problematic connecting lock positions, thereby achieving an assessment of the quality of the assembled furniture from two perspectives, namely the number of problematic assembled furniture and the severity of the problems, as well as the severity of the problems with the connecting locks. This also lays a foundation for further achieving targeted quality control of assembled furniture.
