The embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. As for the methods, products and the like disclosed by the embodiments, the description is simple because the methods correspond to the method parts disclosed by the embodiments, and the related parts can be referred to the method parts for description.
As shown in FIG. 1, the present invention provides a feedback control method for bad information of stations, which mainly comprises the following steps: s101, acquiring bad information of the station, wherein the bad information at least comprises bad types, bad times and bad degrees; s102, extracting station adverse conditions corresponding to adverse information types from a database according to adverse types, wherein the station adverse conditions at least comprise an adverse frequency threshold value and one or more adverse degree conditions; s103, when the number of times of failure is smaller than the threshold value of the number of times of failure and the degree of failure matches one or more of the bad degree conditions of the station bad conditions, calling a preset station bad processing scheme. The feedback control method can combine preset poor station judgment conditions according to the actual poor station problems and timely and effectively call the corresponding processing scheme, and compared with the conventional manual inspection mode, the feedback control method can automatically complete the processing flow of the poor station problems, reduce the delay influence of production and sales caused by the poor station problems and ensure the stable and orderly operation of the production and sales process.
In an embodiment, the bad information of different workstations obtained in step S101 can be classified into one or more bad types, for example, taking a production assembly line of air conditioning products as an example, for a production workstation, the bad types covered by the production workstation include but are not limited to: the failure types can be divided into a plurality of sub-failure types according to specific situations, for example, the allocation amount of the parts is not proper, the allocation amount of the parts is too much, the allocation amount of the parts is too little, and the like, and therefore, in the embodiment, the obtained failure times can be the sum of the sub-failure types belonging to the same failure type or the number of the single sub-failure type.
In an embodiment, the number of bad questions may be the number of times the same type of bad questions occurred within a set period of time, or the number of times the same type of bad questions occurred cumulatively.
In the above embodiment, the bad degree may be divided into a plurality of grades, such as light, general and heavy, according to the severity of the bad information, and different bad degrees of each bad type or sub-bad type correspond to the preset station bad scheme, so that when a bad problem occurs in different stations, corresponding processing may be performed according to the preset optimal station bad scheme, thereby improving the processing efficiency of the bad problem.
In one embodiment, the fault in the station fault conditions related to step S102 corresponds to the fault degrees in different levels, which is different from the way that the fault frequency threshold corresponds to the fault degree in the previous embodiment, and the present embodiment determines the actual fault degree by the fault of the fault problem occurring at a single time, for example, by taking the fault type with improper component distribution amount as an example, the fault conditions of the station fault conditions stored in the database can be classified into the fault degree levels which exceed the basic component distribution amount by 10%, 30% and 50%, respectively correspond to the slight degree, the general degree and the significant degree, and when the improper component distribution amount of a certain station reaches the above fault condition, the fault problem corresponding to the fault degree can be determined to occur in the station.
In another embodiment, the failure frequency threshold in the station failure conditions related to step S102 corresponds to the failure degrees of different levels, for example, taking the failure type with improper component distribution amount as an example, the failure frequency threshold of the station failure conditions stored in the database is divided into 3 times/day, 5 times/day, and 8 times/day, which correspond to the failure degree levels of a slight degree, a general degree, and a significant degree, respectively, and when the occurrence frequency of improper component distribution amount of a certain station reaches the failure frequency threshold, it can be determined that the station has a failure problem corresponding to the failure degree of the level.
Therefore, in the above embodiment of the present invention, the feedback control method further includes: and calling a preset station bad processing scheme when the bad times are larger than the bad time threshold value.
In another embodiment, the failure frequency threshold and the failure condition may be combined to determine the failure degree of the failure problem occurring at the workstation, and the failure degree of the failure problem may be determined when at least one of the failure frequency threshold and the failure condition is satisfied, specifically, the failure condition of the workstation is determined according to the manner in the two embodiments.
In the embodiment shown in fig. 2, the step S103 of invoking the preset workstation bad processing scheme includes the steps of: s201, determining one or more production and sales lines where stations are located; s202, determining other stations of bad information of the associated stations on each production sales line of one or more production sales lines; s203, controlling the stations and other stations on each production and sales line to stop the production and sales line.
Taking an assembly line for air conditioner production as an example, parts to be assembled by an air conditioner include A, B, C, D, E and the like, and since the parts do not need to be assembled in a fixed order, a plurality of assembly lines can be assembled in a plurality of assembly orders for the air conditioner, for example, the assembly order of assembly line No. 1 is a → B → C → D → E, the assembly order of assembly line No. 2 is a → C → D → B → E, the assembly order of assembly line No. 3 is a → C → B → D → E, each part of the above-mentioned 3 assembly lines corresponds to a station, and when a problem occurs in the station corresponding to the B part, step S201 determines all the 3 assembly lines as the associated assembly lines.
Meanwhile, when a problem occurs in the station corresponding to the part B, the other associated stations determined in step S202 are: c, D of the No. 1 assembly line and a station corresponding to the E part, E part of the No. 2 assembly line and D and E parts of the No. 3 assembly line; thus, in step S203, the stations that control the line shut-down include the B part control station and the other stations associated with each production and sales line described above.
In the above embodiment, the problem of the failure of the B part at the station is taken as an example, and since the parts of the plurality of assembly lines are supplied in a unified manner, when the B part of the No. 1 assembly line is broken, the B parts of the No. 2 and No. 3 assembly lines may be broken, and therefore, in step S201, two other assembly lines other than the No. 1 assembly line are associated. In other embodiments, for example, when the B parts of assembly line No. 1 have a bad problem of improper part distribution, since the number of parts of each assembly line is independently distributed, the other two assembly lines may not have the problem, and thus the stations of the other two assembly lines are not related in step S201.
Compared with the mode of stopping the production line totally in the conventional production line process, the control method refines the specific control process, and can reduce the interference influence on other production sales lines or other stations of the same production sales line when a certain station has a bad problem.
In the embodiment shown in fig. 3, the specific flow of invoking the preset workstation bad processing scheme related to step S103 includes: s301, determining one or more production and sales lines where stations are located; s302, determining other stations of bad information of the associated stations on each production sales line of one or more production sales lines; s302, determining the station bad processing flow of the station and each other station, and pushing the station bad processing flow to the corresponding station and other stations.
In this embodiment, the specific processes of step S301 and step S302 may refer to the embodiment of fig. 2, which is not described in detail herein; in step S302, when a problem occurs in a certain station, it may adversely affect other stations associated subsequently, and therefore, the other stations also perform corresponding station bad processing operations after receiving the pushed station bad processing flow, for example, when a problem of part breakage occurs in a certain station, part of the assembled product may have the broken part therein, and therefore the station bad processing flow received by the station includes, but is not limited to: stopping assembling the broken parts; while the station bad processing flows received by other stations subsequently associated include, but are not limited to: and stopping assembling the parts, sending the products to be assembled to inspectors for inspection and the like. Therefore, the station poor treatment process pushed by the invention comprises a first station poor treatment process of a station with a poor problem and a second station poor treatment process of other associated stations, and different stations simultaneously carry out poor problem treatment according to the corresponding station poor treatment processes, so that the treatment efficiency of the poor problem can be accelerated, and the time for recovering normal production and sales is shortened.
