Description

Intelligent production scheduling system of precast beam field

Technical Field

The invention relates to the technical field of precast beam production scheduling, in particular to an intelligent production scheduling system for a precast beam field.

Background

The precast beam is a beam which is transported to a construction site to be fixedly installed according to the position required by design after being precast in a precast beam field.

Introduction of a traditional precast beam field production process: the precast beam yard is an important component part for highway or railway construction. When the standardization degree of the bridge used on the line is high, and the number of bridges of the same type is large, a precast beam yard can be set to carry out unified processing and distribution on the bridge, a beam body needs to be transported to a beam erecting line site by using a beam transporting vehicle after being precast in the beam yard, and the whole process is completed by using a bridge erecting machine to hoist the precast beam to a preset position. Therefore, the precast beam yard has the characteristic of factory building batch processing, and needs a production area (namely a beam manufacturing area), a storehouse (namely a beam storage area and a raw material storage area). Meanwhile, the field beam erection needs to be considered, so that the preparation and storage frame plans which can be matched with each other need to be formulated.

The conventional production flow is as follows: 1. customizing, storing and erecting production plans according to initial factors such as the number of precast beams, the construction deadline of the whole line, the number of bridge erecting machines, the number of precast beam yard pedestals, the number of construction teams and the like, namely when each beam starts to be manufactured, which time period is stored on the layer of which beam storage pedestal, and which day is erected to a preset position; 2. distributing the tasks to various groups according to the production plan for implementation, storing the image data of each production process, and filling and reporting to relevant departments at the later stage; 3. the beam is manufactured in a beam yard and then needs to be placed on a beam storage area pedestal, the beam storage area pedestal can generally store two layers, and when the beam erecting condition of the beam (the construction of a lower part structure on the site is finished and a bridge erecting machine moves to a preset position) is met, the beam is moved to a beam transporting vehicle to be transported to a beam erecting site.

However, due to the tight production task, the factors disturbing the normal production of the precast beam in the whole production cycle are numerous, each link may cause the delay or advance of the production schedule, and there are some situations where the beam needs to be produced in advance or in the delay. With the continuous production, the deviation between the plan compiled in the early stage and the actual production progress is larger and larger, and the construction can not be guided.

If the beams stored in the lower layer are erected in advance than the beams stored on the upper layer in the beam storage area, the beams on the upper layer need to be moved away, and the beams on the upper layer are moved back to the beam storage pedestal after the beams on the lower layer are moved away, so that the problem of secondary beam moving is caused, the production efficiency is reduced, and the secondary carrying cost is increased.

The method is characterized in that the construction requirement degree is high at present, and higher requirements are provided for the production efficiency and the erection efficiency of the precast beam, so that the management problems of beam manufacturing and beam storage of a precast beam field are increasingly outstanding. Although there are many beam field management software and systems, there are problems of poor pertinence of actual requirements and management pain points, large system, redundant functions and the like, and the phenomenon of 'two layers of skins' generally exists in field application.

The existing management software of the precast beam field has the following defects: 1. in the production practice process, the precast beam field is managed roughly, the problem of abnormal beam stacking is serious, and the secondary carrying cost is greatly increased; 2. the field management machine account is not matched with the plan, the manager cannot implement the field management machine account according to the specified plan, and the production rhythm of the beam yard is difficult to pre-judge and control; 3. the filling of the precast beam quality tracing data increases the workload of field management personnel, and the quality tracing is in a form.

With the continuous development of the informatization technology, how to perform informatization intelligent transformation and transformation on the traditional extensive precast beam field management mode is more and more concerned.

The business logic diagram of the intelligent production scheduling tool is shown in fig. 2.

The function and principle of the individual panels will be described in detail below.

1. Plan management module

1) And (3) beam erecting plan: the system initially records a series of initial information such as beam erecting sequence of beams, beam erecting deadline of each beam, daily production capacity of the whole beam yard, beam manufacturing period of each beam and the like. The initial default of the system is that the girder erection stopping time of each girder is the actual girder erection time, an initial girder erection list is discharged according to the actual girder erection, a daily girder erection plan is calculated by combining the daily girder erection efficiency of the bridge girder erection machine, and the actual girder erection time is displayed in a calendar form.

When the actual production condition of a certain beam or a certain batch of beams is not in accordance with the plan, the actual beam erecting time of the selected beam can be modified in the beam erecting list, and the system automatically rearranges the beam erecting plan after modification.

2) Plan to build beams

According to the production capacity of a precast beam field, combining a beam erecting plan sequence to obtain a primary beam manufacturing sequence, simulating and deducing a beam storage plan table of each pedestal of a beam storage area according to the primary beam manufacturing sequence and the beam erecting plan, when the problem of secondary beam moving occurs during simulation deduction, exchanging the beam manufacturing sequences of two corresponding precast beams, avoiding the problem of secondary beam moving in advance, and obtaining a final beam manufacturing sequence table when the simulation deduction is completed.

The secondary beam moving problem refers to the condition that the beams stored at the lower layer are erected earlier than the beams stored above the beams, namely, the phenomenon of overlapping occurs.

The implementation steps of the plan management service logic in the embodiment of the invention are shown in fig. 3, and the implementation steps comprise the following specific steps:

s1, acquiring a beam erecting sequence in the beam erecting plan;

s2, generating a preliminary beam manufacturing sequence according to the beam erecting sequence;

s3, generating a beam storage plan according to the beam erecting sequence and the preliminary beam manufacturing sequence;

s4, judging whether a laminated beam problem exists in the beam storage plan or not by combining the pedestal state of the beam storage plan and the beam storage plan; if the problem of the laminated beams exists, adjusting the beam manufacturing sequence of the precast beams with the laminated beam problem to obtain a final beam manufacturing sequence table, and if the problem of the laminated beams does not exist, directly taking the preliminary beam manufacturing sequence as the final beam manufacturing sequence table;

and S5, updating the beam making sequence table and the beam storage schedule table in real time according to the production schedule. If the system user enters an adjustment to the beam sequence, then return is made to S2.

3) Real-time updated beam making and erecting plan

Due to the fact that the progress is advanced or lagged in the actual production process, even the shelf manufacturing time of some beams can be advanced or delayed due to field reasons, and the well-made production plan is difficult to match with the flexible and variable actual progress.

Therefore, a queuing concept is introduced into the intelligent production scheduling tool, the system and frame beam lists generated by the system are the queuing lists of the precast beams, only the sequence is shown, the system dispatches orders according to the queuing lists, and the planning time of the system and the frame beams is not considered. The system combines the on-site daily frame-making beam capacity according to the sequence in the frame-making list, allocates the precast beams in the frame-making and frame-making beam list to the subsequent days, and displays the precast beams in a calendar. When the production schedule is delayed or advanced, the distribution system and the girder construction plan only need to be recalculated according to the daily girder construction capacity on site. The system order is only related to the sequence of the system and girder erection list, and is not related to the date of the system and girder erection plan, and the date of the system and girder erection plan is calculated in real time on the basis of the system and girder erection list. Therefore, the system and the beam erecting plan displayed on the system can be ensured to change in real time along with the production progress.

The work order dispatching module is used as a core function of the production dispatching tool, and a receiving end user of the work order dispatching module is a member of each team, namely, each team uses a mobile phone end (APP/WeChat applet) to carry out order receiving and quality inspection operation on the beam-making task work orders dispatched by the system.

For the first production process of the precast beam, a proper pedestal needs to be manually selected on the platform for order dispatching, and after the order dispatching is clicked, the system dispatches the order according to the sequence in the beam making list. For example, when the number 1 team receives a long order, the system acquires the start time data of the process and updates the production state of the pedestal in real time. And when the working procedure is completed, the technicians of the No. 1 team are required to click on the mobile phone end to complete the working procedure.

After the previous procedure is completed, the team leader No. 2 clicks to receive orders, and then the technician of team No. 2 checks and approves the completion quality of the previous procedure at first, takes pictures and retains the image data. When the inspection result is unqualified, the system reassigns the work order to the No. 1 team for rework; and if the inspection result is qualified, the team No. 2 formally performs the construction of the process. And when the working procedure is completed, the technician in team No. 2 clicks the working procedure to be completed, and the system sends a list to the subsequent team to continue to carry out approval and construction operation until the construction of the last working procedure is qualified.
