The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Example 1

[0025] Please refer to Figure 1 The structural diagram of a PC plant concrete delivery system provided by the present embodiment shown in the figure, the delivery system 1 comprises: a communication module 2 and a scheduling module 3; the delivery system can control a feeder 10;

[0026] The communication module 2 is used for signal connection with the concrete placing boom system 4, the central control system 5 and the mixing station system 6; the concrete placing boom system 4 and the central control system 5 are used to send concrete delivery task requirements to the conveying system 1; the mixing station system 6 is used to produce concrete; the concrete delivery task requirements at least include: feeding position, running distance, required time and required quantity;

[0027] The scheduling module 3 is used to receive the concrete delivery task requirements and sort them, and control the coordination between the mixing station system 6, the concrete placing machine system 4 and the feeder 10 according to the delivery task requirements.

[0028] Concrete is the main material and the most important material for PC components (prestressed concrete structures). In the current factory. After the concrete is produced by the mixing station system 6, the concrete is transported to the mixing station system 6 by a concrete transport truck, and then transported by the concrete transport truck to each distribution machine system 4 of each production line of the PC factory (a PC factory contains multiple production lines, and each production line may contain multiple distribution points). The current concrete transportation system in the industry is only controlled by the feeder 10 (for example, a concrete transport truck), and lacks intelligent coordinated operation control with the mixing station system 6 and the distribution machine system 4, resulting in low overall operation efficiency and increased costs. To this end, the transportation system proposed in this application can intelligently dispatch the production operation of the mixing station system 6 according to the concrete demand of each distribution machine in the PC production line distribution machine system 4, and intelligently control the feeder 10 to receive materials from the mixing station system 6 and transport them to the corresponding distribution machine.

[0029] Specifically, in this embodiment, the conveying system 1 includes: a communication module 2 and a scheduling module 3, and it can control the feeder 10 to move, receive materials, and unload materials. In addition, in order to achieve multi-party scheduling, the communication module 2 needs to achieve signal connection with the material placing machine system 4, the central control system 5 and the mixing station system 6;

[0030] First, if Figure 1As shown, the conveying system 1 uses sensor technology, frequency conversion control technology, field bus technology, industrial Ethernet technology, network technology, communication technology and intelligent control method to realize conveying control, which can be generally understood as intelligent conveying scheduling technology, intelligent material receiving control technology and intelligent unloading control technology. The system is designed with a scheduling module 3 (scheduling module 3 specifically includes a PLC controller with a high degree of integration) and an industrial Ethernet communication module, which is the communication module; in addition, it also includes a walking control unit 7, a material receiving control unit 8, a material discharging control unit 9 and required detection units, etc. The industrial Ethernet communication module in the system realizes data communication between the conveying system and the central control system, the batching machine system and the mixing station system; the concrete conveying system 1 receives the conveying task requirements from the central control system 5 or the batching machine system 6, performs intelligent optimal sorting of the conveying task requirements, intelligently coordinates the efficient operation of the mixing station equipment system and the batching machine system 6, and controls the intelligent, stable, reliable and efficient operation of the feeder 10 equipment.

[0031] In actual applications, the placing crane system 4 or the central control system 5 can be used to send concrete delivery task requirements to the conveying system 1; the mixing station system 6 is used to produce concrete on demand; in addition to the above-mentioned feeding position, running distance, required time and required quantity, the concrete delivery task requirements also include task priority, transportation time, etc. These parameters are the key to controlling the production and operation of the mixing station system 6; these are received and sorted by the scheduling module 3, and the coordination between the mixing station system 6, the placing crane system 4 and the feeder 10 is controlled according to the sorted delivery task requirements, thereby improving the comprehensive operation efficiency of the conveying system.

[0032] The scheduling module 3 can arrange the delivery task requirements by calculating the parameters and weights of the task priority, feeding position, running distance, transportation time, required time and demand in each of the concrete delivery task requirements, and sorting the multiple concrete delivery task requirements according to the calculation results. For example, the scheduling module 3 can assign weights to the demand parameters such as task priority, feeding position and running distance by constructing a Bayesian network, and then arrange the various concrete delivery task requirements in combination with the parameter size of the demand parameters themselves and the corresponding weights.

[0033] In summary, the conveying system 1 has intelligent conveying scheduling technology, which can intelligently analyze and select the best delivery plan for all conveying tasks in real time and dynamically, and schedule the execution, solving the problems of unscientific, inaccurate and inefficient manual scheduling, and realizing stable and efficient concrete transportation to meet the overall concrete transportation needs of the PC factory. In the actual application process, if there is a new task queue when the current conveying task is completed, each task in the current task queue is first read, and the priority, feeding position, running distance, transportation time, required time, demand and other information of each task are identified. At the same time, each task in the newly added task queue is read, and the priority, feeding position, running distance, transportation time, required time, demand and other information of the task are identified. Then, for each task, according to the priority, feeding position, running distance, transportation time, required time, demand and other parameters and their weights, the optimal conveying task queue is arranged according to the algorithm.

[0034] Furthermore, the scheduling module 3 needs to control the coordination among the mixing station system 6, the material placing machine system 4 and the feeder 10 according to the transportation task requirements.

[0035] The scheduling module 3 includes: a travel control unit 7, a material receiving control unit 8 and a material discharging control unit 9;

[0036] The travel control unit 7, the material receiving control unit 8 and the material discharging control unit 9 are respectively used to control the moving speed, material receiving and material feeding of the feeder 10 between the material placing machine system 4 and the mixing station system 6. In view of practical applications, the feeder 10 is mainly used to control the material receiving of the mixing station system 6 and send the material to the designated material placing machine in the material placing machine system 4.

[0037] In addition to controlling the movement, material receiving and material delivery of the feeder 10 , the above-mentioned units also need to coordinate and control the material placing machine system 4 and the mixing station system 6 .

[0038] Specifically, the material receiving control unit 8 is used to receive the concrete delivery task requirements, and send control instructions to the mixing station system 6 according to the concrete delivery task requirements, and the control instructions at least include: start, stop, and required concrete production; such a design can ensure that when the feeder 10 moves to the material receiving position at a calculated speed (calculated based on the required time and running distance), the mixing station system 6 has produced concrete; the material receiving position is located at the discharge port of the mixing station system 6, thereby improving the material receiving efficiency.

[0039] In summary, the conveying system 1 also has intelligent material receiving control technology, which can intelligently and efficiently schedule the production start-up, unloading, and production end of the concrete mixing station system 6 according to the conveying task, and call the travel control unit 7 to complete the efficient material receiving process of the conveying equipment (feeder 10). This technology realizes the efficient and stable operation of the material receiving process by calling the travel control unit 7; the operation time of the mixing station system 6 is determined in combination with the currently executed conveying task, ensuring that when the feeder 10 arrives at the material receiving position, the concrete of the mixing station system 6 is just completed, realizing energy saving and maximizing the overall operation efficiency.

[0040] Furthermore, after the mixing station system 6 finishes unloading, it will send information such as the completion of unloading, the weight of the unloaded materials, and the volume of the unloaded materials, and the feeder 10 will complete the material receiving process. This technology solves the problems of low efficiency, high consumption, and poor information flow caused by manual scheduling of mixing station operation and inability to identify concrete production information, and realizes energy-saving and efficient material receiving control.

[0041] Furthermore, the material discharging control unit 9 is also used to control the material receiving of the corresponding concrete placing machine in the concrete placing machine system 4, so as to realize the coordinated docking of the unloading start of the feeder 10 and the concrete placing machine system 4; the concrete placing machine system 4 is used to transport concrete to the next process.

[0042] The discharging control unit 9 is used to control the discharging speed of the feeder 10 according to the rotation angle of the feeder 10 and the remaining concrete.

[0043] In summary, the conveying system 1 also has intelligent unloading control technology, which intelligently controls the unloading process of the feeder 10 and the material receiving process of the material placing machine system 4, realizes the start of unloading, the unloading process and the intelligent coordination and docking of the material placing machine, and can also control and adjust the unloading speed, unloading angle, and material receiving state of the material placing machine equipment of the feeder 10 to realize fast and stable unloading throughout the whole process. This is because when the feeder 10 rotates to discharge the material, the concrete throwing point will change with the rotation angle and rotation speed. In order to prevent the material from being scattered and the material is discharged quickly, the unloading process will automatically adjust the discharge speed of the feeder 10 according to the parameters such as the rotation angle, the remaining material and the fine-tuning algorithm, and also coordinate with the material placing machine system 4 to realize stable and efficient unloading process.

[0044] In summary, combined with Figure 1 and Figure 2The present application provides a PC factory concrete delivery system, which mainly includes communication control technology, intelligent delivery scheduling technology, intelligent material receiving control technology, intelligent unloading control technology, etc., to realize the intelligent delivery of concrete by equipment. On the one hand, the present application coordinates the current PC factory concrete production, receiving, transportation, unloading and other processes through the communication module and the scheduling module. For example, when a distributor in the distributor system 4 sends a concrete delivery task demand, the scheduling module 3 sends a control instruction to the distributor system 4 and the mixing station system 6 through the corresponding data serial port according to the delivery task demand. The control instruction includes starting the mixing station system 6 to mix the concrete corresponding to the demand, and discharging the material according to the corresponding feeding position, etc. In addition, after the feeder 10 receives the concrete after mixing by the mixing station system 6, the scheduling module 3 receives the completion signal and sends a waiting instruction to the corresponding distributor in the distributor system 4. When the feeder 10 reaches the receiving position of the distributor, the distributor completes the unloading. The system improves the operating efficiency of the entire PC plant, reduces labor, and basically eliminates idling of concrete conveying-related equipment, achieving energy conservation, carbon reduction, and consumption reduction.
