Embodiment 1

[0045] Such as figure 2As shown, to produce a certain equipment, n assembly lines are required, and each assembly line is equipped with m assembly and processing stations; The working hours Gj are specifically taken as follows:

[0046] Step 1: Obtain the first station, that is, the station at the first position of the n assembly lines, and obtain the time required for processing a single workpiece. The specific acquisition method is:

[0047] S1: Obtain the entry signal when the workpiece enters the first station and the departure signal when it leaves the first station through the station monitoring module;

[0048] S2: When the workpiece enters from the station, the timing starts when the entry signal is generated, and the timing stops when the workpiece leaves the station and the departure signal is generated. The time between the start of timing and the stop of timing is the processing time of a single workpiece;

[0049] S3: Acquire the processing time of a single wor...

Embodiment 2

[0055] The self-analysis unit is used for self-analysis and processing of the single man-hour group Gj of the data temporary storage unit, specifically:

[0056] SS1: Calculate the average value Pg of the single-piece man-hour group Gj,

[0057] SS2: After using the formula Calculate the stable value W;

[0058] SS3: Remove G1 to obtain a new single-piece man-hour group G g1 ;

[0059] SS4: Calculation of new unit hours group G g1 mean value of P g1 , And calculate the destabilization value W1,

[0060] SS5: Remove G2 to obtain a new unit-hour group G g2 , then repeat the principle of step SS4 to calculate the corresponding destabilizing value W2; remove G3~Gm in turn to obtain the destabilizing value group Wj composed of m destabilizing values, j=1, 2, 3, ..., m, m is a positive integer;

[0061] SS6: According to the analysis of destabilizing value Wj, stabilizing value W, unit working hours Gj, and average value Pg, cumbersome work stations are obtained; the ...

Embodiment 3

[0065] The way to obtain the entry signal and exit signal is:

[0066] Such as figure 2 As shown, the observation area is set at the specified distance before and after the station; specifically, as figure 2 As shown, the observation area A and the observation area B are set at the specified distance before and after the station C1, and the photos of the two observation areas are obtained through the station monitoring module, and are respectively marked as the front observation map T q and post-observation graph T h , after which the real-time photos of the front and rear observation areas are obtained every interval T1, and the obtained real-time photos are respectively compared with the corresponding front observation map T q and post-observation graph T h Compare and obtain the area of ​​the difference;

[0067] Current and previous observation graph T q When the difference area exceeds the preset value, an entry signal is generated;

[0068] When and after observi...

Abstract

The invention discloses a multi-station data acquisition and processing system of a flow assembly line, and relates to the technical field of data acquisition. The system comprises a station monitoring module, a data accumulation module, a data temporary storage unit, a self-analysis unit, a processor, a storage unit, a display unit, a suggestion generation unit and a management unit. The stationmonitoring module is used for monitoring a plurality of flow assembly lines with the same operation at the same time, and the self-analysis unit is used for carrying out self-analysis processing on asingle-piece man-hour group Gj of the data temporary storage unit to obtain tedious stations. According to the invention, inductive analysis is carried out on the condition of each station to obtain individual stations with relatively long occupied time, and the stations with relatively long occupied time are positioned and are suggested to be split so that the overall stations are reasonably planned, the condition of unreasonable station procedure arrangement is avoided, and intelligent management is realized; and the system is simple, effective, easy and practical.

Description

technical field [0001] The invention belongs to the technical field of data acquisition, and in particular relates to a multi-station data acquisition and processing system of an assembly line. Background technique [0002] Publication number is that the patent of CN107065793A discloses pipeline real-time monitoring management method and device. The assembly line (100) includes N stations arranged in sequence along the transport direction (D), where N is an integer greater than 1. The method includes: collecting the quantity of products respectively processed by the Nth station and the total working time of the assembly line (100), receiving the expected production beat of the assembly line (100); position and the number of semi-finished products between the n+1 station to judge the working state of the n station, wherein, n is an integer from 1 to N-1; calculate the efficiency of the assembly line (100) to judge the The working status of the Nth station; and output a data...
