Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The method for dispatching the concrete mixing equipment to the material can be applied to the application environment shown in figure 1. The terminal 102 communicates with the distribution equipment 104, the concrete mixing equipment 106 and the concrete conveying equipment 108 through a network. The terminal 102 receives material requiring instructions of at least two production line material distribution devices; acquiring production task information of distribution equipment of each production line and a corresponding production line priority sequence; determining the priority sequence of each material requiring instruction according to the production task information and the production line priority sequence of each production line material distributing device; based on the priority sequences, sequentially sending a first feeding instruction to the concrete mixing equipment; the first feeding instructions are used for controlling the concrete stirring equipment and the concrete conveying equipment to complete feeding scheduling for the production line material distribution equipment according to the stirring formula corresponding to each first feeding instruction. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, and tablet computers.

In one embodiment, as shown in fig. 2, there is provided a method for scheduling material feeding of a concrete mixing plant, which is exemplified by the application of the method to the terminal in fig. 1, and includes the following steps:

step 202, the control unit receives a material requiring instruction of at least two production line material distribution devices.

The material requiring instruction is generated according to a real-time concrete weight value and a material requiring weight threshold value in production line material distribution equipment corresponding to each concrete prefabricated part, namely when the real-time concrete weight value in the production line material distribution equipment is smaller than the material requiring weight threshold value, the production line material distribution equipment sends the material requiring instruction to a terminal, wherein the terminal comprises a material requiring scheduling control unit (PLC) and a production informatization control unit; the material weight threshold is obtained by converting a time threshold determined by combining the material preparation time of the concrete stirring equipment and the single transportation time of the concrete conveying equipment according to the concrete consumption speed of the distribution equipment of each production line. The concrete prefabricated part is produced by conveying the material stirred by the concrete stirring equipment to the distribution equipment of each production line through the concrete conveying equipment; the two production line distributing devices correspond to different production lines respectively.

Different concrete prefabricated parts need different production line distribution equipment to be produced, and the different production line distribution equipment has corresponding production lines; the proportions of various concrete materials of different precast concrete components can be different or the same, for example, the proportions of the materials in the precast concrete component A are "mud: sand: stone: the proportion of water, the proportion of materials in the B concrete prefabricated part is' mud: sand: stone: water: the glass fiber' and the concrete C prefabricated part are prepared from the following materials: sand: stone: water: lime is used.

Specifically, when the real-time concrete weight value in the production line material distribution equipment is smaller than the material requiring weight threshold value, the production line material distribution equipment sends a material requiring instruction to the terminal, and when the terminal receives the material requiring instructions of at least two production line material distribution equipment at the same time, the production task information and the corresponding production line priority order of each production line material distribution equipment are obtained.

And 204, the control unit acquires the production task information of the distribution equipment of each production line and the production line priority of the production line in which the distribution equipment of each production line is located.

The production task information comprises unfinished concrete prefabricated part production tasks of distribution equipment of each production line and/or new task requirements of concrete prefabricated part production of the production line. The production line priority order refers to the importance degree of the feeding of the concrete prefabricated parts produced by each production line, and is determined according to the demand characteristics of the produced concrete prefabricated parts and the distribution equipment of the production line.

For example, the process for producing the concrete prefabricated part of the fabricated building comprises three production line distribution devices of a circulating die table distributor, a long die table distributor and a group formwork erection distributor; the long platform line for conveying the concrete material to the long-platform distributing machine is very long (for example, 150 meters), the concrete material is solidified when the concrete material stops stirring, and if the concrete material is solidified before vibration compaction, air bubbles can be generated in the member, so that the quality of the prefabricated member can be influenced; in addition, if the concrete transportation and the feeding of the same component are delayed due to conflict, the time difference between the front and the rear material distribution is long, and the quality and the yield of products are further influenced. The principle of the grouped vertical die distributing machine is the same as that of the long die table distributing machine, and components produced by the grouped vertical die distributing machine can vibrate in a layered mode, so that the feeding priority of the grouped vertical die distributing machine is slightly lower than that of the long die table distributing machine. The cloth production of circulation mould platform cloth machine has certain law, so the material loading priority of circulation mould platform cloth machine is less than the material loading priority of long mould platform cloth machine and group's upright mould cloth machine, can confirm that the material loading priority of circulation mould platform cloth machine, long mould platform cloth machine and group's upright mould cloth machine is: long die table distributing machine, group vertical die distributing machine and circulating die table distributing machine.

Specifically, a control unit of the material requiring scheduling in the terminal acquires production task information and a corresponding production line priority of each production line material distribution device from a server corresponding to the production information control unit.

And step 206, determining the priority order of the material requiring instructions according to the production task information of the material distributing equipment of each production line and the priority order of each production line.

The priority order is the priority of the effective material requiring instruction determined according to the production task information of each production line material distributing device.

Specifically, whether a corresponding material requiring instruction is effective is detected according to production task information of each production line material distribution device, and an effective material requiring instruction sequence is determined; and sequencing the effective material command sequences according to the production line priority sequence of the production line material distribution equipment to obtain the priority sequence of each effective material command in the effective material command sequences. For example, when the terminal receives a material requiring instruction sent by a material distributing device of a production line, the production task information of the material distributing device of the production line a is acquired, if an unfinished concrete prefabricated part production task does not exist in the material distributing device of the production line a, the material requiring instruction sent by the material distributing device of the production line a received by the terminal is an invalid instruction, the material requiring instruction sent by the material distributing device of the production line a is deleted from the received material requiring instruction, and the priority of the remaining valid material requiring instructions is updated.

Step 208, sequentially sending a first feeding instruction to the concrete mixing equipment based on the priority order; the first feeding instructions are used for triggering the control unit and controlling the concrete mixing equipment to complete feeding and mixing for production line material distribution equipment according to mixing formulas corresponding to the first feeding instructions.

The concrete mixing equipment is used for mixing materials of the material distribution equipment of the production line, the concrete mixing equipment can be but is not limited to a mixing station, and the corresponding monitoring control unit exists in the concrete mixing equipment and is used for monitoring the mixing formula, the mixing duration and the like of the concrete mixing equipment.

Specifically, the feeding instructions are sequenced based on the priority sequences, first feeding instructions are sent to the concrete mixing equipment in sequence, the concrete mixing equipment obtains a corresponding mixing formula according to the received first feeding instructions, and feeding and mixing are completed for production line material distribution equipment according to the mixing formula.

Optionally, in the feeding and stirring process of the concrete mixing equipment, the currently received material requiring instruction is locked until the next material requiring instruction is executed when the concrete mixing equipment completes feeding, and the currently received material requiring instruction is locked, so that the problem that the material requiring scheduling sequence is disordered due to repeated material requiring of the current production line material distribution equipment in the feeding process is avoided, and the generation efficiency and yield of the concrete prefabricated part are reduced. As shown in fig. 3, which is a schematic diagram of locking and switching the material demanding instructions in the feeding process in one embodiment, the process for producing the concrete prefabricated parts of the prefabricated building includes three production line distributing devices, namely a circulating die table distributing machine, a long die table distributing machine and a group vertical die distributing machine, and the feeding priorities of the circulating die table distributing machine, the long die table distributing machine and the group vertical die distributing machine are as follows: the long-formwork-table distributing machine, the group vertical-formwork distributing machine and the circulating-formwork-table distributing machine sequentially lock a currently received material-requiring instruction in the feeding and stirring process of the concrete mixing equipment until the next material-requiring instruction is executed when the concrete mixing equipment completes feeding.

And step 210, when detecting that the concrete mixing equipment completes mixing, triggering the concrete conveying equipment to convey the mixed materials to corresponding production line material distribution equipment, and completing material scheduling.

The concrete conveying equipment is used for conveying the stirred materials to the corresponding production line distributing equipment, wherein corresponding relations exist between the concrete conveying equipment and the production line distributing equipment, for example, the concrete conveying equipment A is responsible for concrete material transportation of the production line distributing equipment A, and the concrete conveying equipment B is responsible for concrete material transportation of the production line distributing equipment B.

Specifically, when the concrete mixing equipment is detected to finish mixing, a blanking instruction is generated; triggering concrete conveying equipment to reach a specified discharge port through the blanking instruction based on the discharge port corresponding to each production line material distribution equipment; when a completion signal that the concrete mixing equipment completes blanking is detected, the concrete conveying equipment is triggered to reach the corresponding production line distributing equipment, the stirred materials are conveyed to the corresponding production line distributing equipment, and the material scheduling of each production line distributing equipment is completed.

In the material requiring scheduling method of the concrete mixing equipment, the material requiring instructions of at least two production line material distributing equipment are received; acquiring production task information of distribution equipment of each production line and a corresponding production line priority sequence; determining the priority sequence of each effective material requiring instruction according to the production task information and the production line priority sequence of each production line material distributing device; based on the priority sequences, sequentially sending a first feeding instruction to the concrete mixing equipment; the first feeding instructions are used for controlling the concrete stirring equipment and the concrete conveying equipment to complete feeding scheduling for the production line material distribution equipment according to the stirring formula corresponding to each first feeding instruction. The priority order of the effective material requiring instructions is determined according to the priority of the material distributing equipment of each production line and the production task information, the material requiring scheduling of the concrete stirring equipment is realized based on the priority order of the effective material requiring instructions, the automation degree of the concrete conveying equipment is improved, and further the production efficiency of the concrete prefabricated part is improved.

In an embodiment, as shown in fig. 4, there is provided a step of generating a feeding instruction, which is described by taking the method as an example of being applied to the terminal in fig. 1, and includes the following steps:

step 402, obtaining the total time length from feeding to stirring completion of the concrete stirring equipment.

And step 404, acquiring the single transportation time, the distribution completion time, the real-time concrete weight value and the total concrete weight value of the production line distribution equipment corresponding to each concrete prefabricated part.

Wherein, it is long for concrete transportation equipment to produce line cloth equipment's that corresponds length of time with concrete transportation from the discharge gate during the time of single transportation, and the length is different during the single transportation of concrete transportation equipment on the different production lines. Different production lines are provided with corresponding concrete transportation equipment, and the concrete transportation equipment can be but not limited to a torpedo tank.

And 406, determining a corresponding material weight threshold according to the total time length of the material distribution equipment of each production line, the single transportation time length, the material distribution completion time length and the total weight value of the concrete.

Specifically, determining a time length threshold value of each production line material distribution device according to the total time length, the single transportation time length and the material distribution completion time length; and determining a corresponding material weight threshold according to each time length threshold and the total weight value of the concrete of each production line material distribution device. The method comprises the steps of taking the material preparation and mixing time of a concrete mixing plant, the feeding time of a torpedo tank and the feeding time of a mixing plant as the material requiring time in advance, determining the time length threshold of each production line according to the material completing time length and the material requiring time in advance, determining the time length ratio of each time length threshold to the corresponding material completing time length, determining the time length ratio of each production line according to the time length threshold and the material completing time length, and determining the corresponding material requiring weight threshold according to the product of the time length ratio and the total concrete weight value.

In one embodiment, as shown in fig. 5, the concrete feeding schedule includes three production lines of a long wire distributor, a circulation wire distributor and a group wire distributor, the concrete mixing equipment has two discharge ports, an a discharge port and a B discharge port, and the three PC production lines are supplied with concrete respectively; wherein, the time length of single transportation of the torpedo cars on the long platform line is t1, the time length of single transportation of the torpedo cars on the circulating line is t2, and the time length of single transportation of the torpedo cars on the grouped line is t 3. Taking a long platform line as an example, T1 represents the distribution completion time of a long platform line distribution machine, then T1- (T0+ T1) is the threshold time of the long platform line, when the long platform line reaches the distribution time T1- (T0+ T1), the long platform line is required to be charged, the weight of the remaining concrete is converted into the required material weight threshold, the required material weight threshold is the product of the time ratio and the total weight value of the concrete in the storage bin, the time ratio T1- (T0+ T1)/T1 is the total weight value of the concrete in the storage bin is Q1, and the required material threshold is (T1- (T0+ T1)/T1) × Q1. T2 represents the distribution completion time of the circulation line distributor, and Q2 represents the total weight value of the concrete in the storage bin of the circulation line distributor; t3 represents the completion time of distribution by the gang distributor, and Q3 represents the total weight of the silo concrete by the gang distributor. In the same way, the feeding threshold value of the recycle line distributing machine is (T2- (T0+ T2)/T2) × Q2, and the feeding threshold value of the strand-grouping distributing machine is (T3- (T0+ T3)/T3) × Q3.

And step 408, when the real-time concrete weight value is less than or equal to the material requiring weight threshold value, generating a material requiring instruction corresponding to the material distributing equipment of the production line.

Optionally, in an embodiment, when the real-time concrete weight value is less than or equal to the material demanding weight threshold and the real-time concrete weight value is less than the set concrete weight value, a material demanding instruction corresponding to the material distributing equipment of the production line is generated; the concrete weight value is set for ensuring production of the precast concrete member to be completed. Whether the material requiring instruction is generated or not is determined according to the material requiring weight threshold and the set concrete weight value, generation of an invalid material requiring instruction is avoided, and the processing efficiency of the material requiring scheduling control unit is improved.

In the material demanding instruction generating step, the corresponding material demanding weight threshold value is determined according to the total time length of the concrete mixing equipment from feeding to stirring completion and the single transportation time length of the concrete mixing equipment on each production line material distributing equipment, the time length of material distributing completion and the total concrete weight value, and the concrete weight value is obtained in real time.

In another embodiment, as shown in fig. 6, there is provided a method for scheduling material to be mixed in a concrete mixing plant, which is exemplified by the application of the method to the terminal in fig. 1, and includes the following steps:

step 602, obtaining the total time length from feeding to stirring completion of the concrete stirring equipment.

Step 604, acquiring the single transportation time, the distribution completion time, the real-time concrete weight value and the total concrete weight value of the production line distribution equipment corresponding to each concrete prefabricated part.

And 606, determining a corresponding material weight threshold according to the total time length of the material distribution equipment of each production line, the single transportation time length, the material distribution completion time length and the total weight value of the concrete.

And 608, when the real-time concrete weight value is smaller than or equal to the material requiring weight threshold value and the real-time concrete weight value is smaller than the set concrete weight value, generating a material requiring instruction corresponding to the material distributing equipment of the production line.

Wherein the set concrete weight value is used to ensure production of the precast concrete component to be completed.

Specifically, when the real-time concrete weight value is detected to be smaller than or equal to the material requiring weight threshold value, if the fact that the remaining concrete in the material distributing equipment of the production line is enough to produce the remaining components is determined, the material requiring instruction is not generated; if the concrete left in the material distribution equipment of the production line is enough to produce the left components, the material is required, namely, a material requirement instruction is generated.

Step 610, receiving a material requiring instruction of at least two production line material distribution devices.

Optionally, in an embodiment, the material scheduling control unit of the terminal may obtain the automatically generated material feeding instruction and the manually input material feeding instruction at the same time.

Step 612, acquiring production task information of each production line material distribution device and a production line priority order of a production line in which each production line material distribution device is located.

And 614, determining an effective material requiring instruction sequence by detecting whether the corresponding material requiring instruction is effective according to the production task information of each production line material distributing device.

And 616, sequencing the effective material command sequences according to the production line priority sequence of the production line material distribution equipment to obtain the priority sequence of each effective material command in the effective material command sequences.

Step 618, sequentially sending a first feeding instruction to the concrete mixing equipment based on the priority order; the first feeding instructions are used for triggering the control unit to control the concrete mixing equipment to complete feeding and mixing for production line material distribution equipment according to the mixing formula corresponding to each first feeding instruction.

And step 620, when detecting that the concrete mixing equipment completes mixing, sending a second feeding instruction to each production line material distribution equipment.

Optionally, in an embodiment, the scheduling control unit in the terminal determines a current production line material distribution device to be loaded, sets a material demanding instruction corresponding to the current production line material distribution device as an invalid material demanding instruction, and feeds back a feedback signal indicating that the material demanding instruction is successfully received to the corresponding production line material distribution device until the discharging instruction of the concrete mixing device and the loading instruction of the material distribution line device are generated when it is detected that the concrete mixing device completes mixing.

And 622, based on the discharge ports corresponding to the distributing devices of the production lines, triggering the control unit through the second loading instruction to control the concrete conveying device to convey the stirred materials to the corresponding distributing devices of the production lines, and finishing material scheduling.

Specifically, when the concrete mixing equipment is detected to finish mixing, a blanking instruction of the concrete mixing equipment is generated, and when the concrete conveying equipment reaches a discharge port corresponding to each production line distributing equipment, blanking is finished based on the blanking instruction of the concrete mixing equipment; when the control unit receives a feedback signal of the concrete stirring equipment after blanking is completed, the control unit controls the concrete conveying equipment to convey the material to the corresponding production line material distribution equipment; when an arrival signal reaching the material distribution equipment of the production line is received, a blanking instruction of the concrete conveying equipment is generated; based on the feeding port of the production line distributing equipment to which the blanking instruction is sent, the second feeding instruction triggers the control unit to control the concrete conveying equipment to convey the stirred material to the corresponding production line distributing equipment, and the material scheduling of the production line distributing equipment is completed.
