[0038] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0039] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a method and system for fully automatic storage in a raw material yard.

[0040] Example 1

[0041] The present invention discloses a fully automatic method for adding material to a raw material warehouse. Raw materials from outside the factory are transported to the warehouse by car or train. A stacker stacks the materials in a fixed grid or pile in an orderly manner according to the material type. If the raw material warehouse needs to be added, a reclaimer in the warehouse will drive to the corresponding material location, pick up the material onto a belt, and transport it to the feeder at the top of the raw material warehouse via the belt. Finally, the feeder adds the material to the raw material warehouse, completing the replenishment of the raw material warehouse.

[0042] In this embodiment, if Figure 1 A method for fully automatic loading of raw materials in a raw material yard, comprising:

[0043] S100. Obtain real-time status information of the material yard equipment through a variety of sensors; specifically, the real-time status information of the material yard equipment includes at least the position information of the reclaimer, the working status information of the reclaimer, the position information of the feeder, the working status information of the feeder, the belt information, the silo material weight information, and the silo working status information. Among them, the position information of the reclaimer and the feeder can be obtained through GPS or Beidou positioning modules, and their working status, such as whether they are running or faulty, can be obtained using vibration sensors, temperature sensors, or current monitoring sensors. Belt information involves the running speed and load conditions of the conveyor belt, which requires an encoder to measure the speed, and a pressure sensor or infrared sensor to monitor the material distribution. The silo material weight information can be obtained using a weighing sensor, such as a resistance strain gauge sensor, and the working status of the silo, such as whether it is full or empty, may require an ultrasonic sensor or radar sensor to measure the material level.

[0044] In this embodiment, intelligent devices such as the reclaimer, feeder, belt and sensor need to be connected to the PLC controller. The PLC controller collects and processes various data during the raw material silo addition process, such as material flow, silo level, equipment operating status, etc., and uploads this data to the central server system to facilitate operators to monitor and manage the production process in real time.

[0045] S200. By analyzing the real-time status information of the material field equipment, an actual operation task plan is generated;

[0046] In S200 of this embodiment, the actual operation task plan is generated by analyzing the real-time status information of the material field equipment, such as Figure 2 Specific methods include:

[0047] Obtain the weight information of each raw material bin and transmit it to the central server, which calculates the remaining time of each raw material bin;

[0048] After calculating the remaining time of each raw material bin, sort the bins by the one with the shortest remaining time. If the bin with the shortest remaining time is within the set safety threshold and is not being restocked, the bin with the shortest remaining time is selected for restocking.

[0049] According to the location of the raw material warehouse, the available material line numbers, i.e., paths, are matched. The corresponding reclaimer, belt, and feeder information of each path is obtained, and the time consumed in adding materials to each path is calculated. The path with the shortest time consumption is used as the actual task plan.

[0050] In some preferred embodiments, the remaining time is calculated as follows:

[0051] TL i =Weight i / (OutV i )

[0052] Among them, represents the remaining time of the i-th warehouse, represents the current inventory of the i-th warehouse, and represents the discharge speed of the i-th warehouse.

[0053] In some preferred embodiments, the information of the reclaimer, belt, and feeder corresponding to each path is obtained, and the time consumption for adding material to each path is calculated. The time consumption is calculated as follows:

[0054] Time=PickCarMoveTime+AddCarMoveTime+LineChangeTime

[0055] Among them, PickCarMoveTime represents the movement time of the material picker, AddCarMoveTime represents the movement time of the material feeder, and LineChangeTime represents the material line switching time.

[0056] S200 disclosed in this embodiment generates an actual work task plan by analyzing the real-time information of the material yard equipment. The first step of this step is to calculate the remaining time of the material in each silo in the material yard, and sort all the materials to be added to the silo in the material yard from small to large according to the remaining time. The second step is to select the material with the shortest remaining time as the target material, and record its silo number. The third step is to enumerate various possible silo addition paths, and calculate the preparation time of each path. The preparation time is composed of the moving time of the material reclaimer, the moving time of the feeder, and the start and switching time of the belt. Finally, the path with the shortest preparation time is selected as the silo addition plan. Through the above process, we can make full use of the real-time status information of the material yard equipment to generate an efficient and feasible work task plan, thereby improving the operational efficiency and benefits of the material yard.

[0057] S300. Convert the operation task plan into specific equipment control commands, execute the specific equipment control commands, and realize fully automatic loading of the raw material yard. The specific equipment control commands at least include a reclaimer movement command, a belt start command, and a feeder movement command.

[0058] In S300 of this embodiment, the specific equipment control command is executed, which specifically includes three stages: equipment preparation, starting to reclaim materials, and ending to reclaim materials. Equipment preparation includes reclaimer preparation, feeder preparation, and material line preparation, and the three types of equipment can operate simultaneously.

[0059] In S300 of this embodiment, the raw material yard is fully automatically loaded, and the specific method includes: after the material reclaimer receives the action command, it will move to the target material reclaiming grid; after the material feeder receives the action command, it will move to the target material feeding bin; after the material line receives the action command, each belt on the material line will start running; after the material reclaimer receives the material reclaiming command, it starts to reclaim the material and transfers the material to the material feeding trolley through the belt, and finally adds the material to the silo through the material feeding trolley; after the weight of the material in the silo reaches a certain threshold, the material reclaimer and the material feeder will receive a stop command, and the material reclaimer and the material feeder will immediately stop feeding, and the loading is completed.

[0060] This embodiment discloses a method for fully automatic stocking of raw materials, comprising: obtaining real-time status information of the material yard equipment through a variety of sensors; generating an actual operation task plan by analyzing the real-time status information of the material yard equipment; converting the operation task plan into a specific equipment control command, and executing the specific equipment control command to achieve fully automatic stocking of the raw materials. The present invention implements an automatic stocking system for the raw materials yard. The automatic stocking system can monitor the material status in real time, generate a stocking plan based on demand, and automatically schedule equipment to retrieve materials, thereby ensuring the continuous and stable operation of the production line. This reduces the frequency of manual intervention, improves the degree of automation of the production line, and thus improves overall production efficiency.
