Description

Technical Field

[0001] The present invention relates to the technical field of power grid material storage and network access material quality management, and in particular to an integrated power material storage and inspection system and method. Background Art

[0002] In recent years, large-scale livelihood power projects such as urban and rural distribution network upgrade and transformation projects, coal-to-electricity projects, and Xiong'an New Area high-reliability distribution network construction have been widely promoted across the country. The task of supplying and guaranteeing engineering materials is very heavy, and the quality management of power materials entering the grid is unprecedentedly difficult. In order to ensure the quality of power grid projects, power grid construction management units conduct random inspections on the quality of newly purchased power materials entering the grid.

[0003] At present, most provinces have built central warehouses for storing power materials. After the materials arrive and enter the warehouse, the material management unit samples the materials in the warehouse on a periodic basis and sends the samples to the testing agency to conduct quality inspection of the materials entering the network. At this stage, due to the geographical separation of the central warehouse and the testing agency, there are risks such as long testing cycle and sample replacement during the sampling and sending process when sending samples to the testing agency for quality inspection. The central warehouse cannot grasp the progress of material inspection in real time, which has buried certain hidden dangers for ensuring the timely supply of materials and the quality of materials entering the network. In addition, the central warehouse and the testing agency are separated in geographical location, and the materials for sampling inspection need to be transported back and forth between the central warehouse and the testing agency, which indirectly increases the cost of sampling inspection and is not conducive to improving the quality and efficiency of enterprises.

[0004] At present, there are systems and methods for material warehousing management. "CN 107512515 A Unmanned Intelligent Dense Warehousing Management Method and Warehousing System" discloses an unmanned intelligent dense warehousing management method, including a warehousing method and a warehousing method, as well as an unmanned intelligent dense warehousing system, which can realize the operation of stacking and warehousing, destacking and warehousing by industrial robots, and realize the functions of anthropomorphic sorting, distribution of goods, picking and returning to the warehouse. By using PLC detection and analysis technology, the shuttle robot and freight elevator can change floors up and down to realize the flexible warehousing and warehousing process of goods. The shelves are modularly assembled and can realize multi-layer stereoscopic warehouses. However, this invention is only used for warehousing management and does not involve material sampling. Upon investigation, no public technical solutions related to the integration of storage and inspection of power materials have been found. Summary of the invention

[0029] Furthermore, material transportation equipment is installed in the corridor.

[0030] An integrated method for storage and inspection of electric power materials comprises the following steps:

[0031] S1: Generate material sampling and testing plan: After the warehouse management system generates a material sampling plan according to the material supply plan, it pushes the sampling plan to the central control system of the material quality inspection unit. The central control system generates a testing plan and feeds the testing plan back to the warehouse management system.

[0032] S2: Confirmation and warehousing of arrived materials: After the materials arrive at the central warehouse, the RFID tag information of the materials is read and sent to the warehouse management system for confirmation of the arrived materials information. After the materials are confirmed, the warehouse management system sends the warehouse location information and the material warehousing command to the warehouse control system based on the material information obtained by scanning;

[0033] The warehouse control system receives and decomposes the warehousing order, and issues instructions to the AGV unmanned forklift, automatic conveyor line, palletizer, and stacker to transport the materials to the designated warehouse. After the materials enter the warehouse, the warehouse control system sends a signal that the materials have been warehousing completed to the warehouse management system.

[0034] S3: Material sampling: After all the materials have been put into storage, the warehouse management system determines whether the newly arrived materials need to be sampled according to the material sampling plan. If sampling is required, the warehouse management system freezes the warehouse for the newly arrived materials. The warehouse management system sends a sampling command to the automatic conveying unit according to the inspection and test plan. The automatic conveying unit transports the sampled materials to the blind sample making unit for blind sample making;

[0035] S4: Blind sample preparation of materials to be inspected: After the sampled materials arrive at the blind sample preparation unit, the blind sample preparation device and the label stripping machine cooperate to remove and label the materials;

[0036] S5: Blind sample inspection: After the blind sample is made, the warehouse management unit sends a logistics signal to the material quality inspection unit, and the automatic conveying unit transports the materials to be inspected to the docking position of the material quality inspection unit through the corridor; after receiving the logistics signal from the warehouse management unit, the material quality inspection unit generates a logistics dispatch instruction according to the type of materials to be inspected and the status of the test and inspection station, and issues it to the AGV transport vehicle. The AGV transport vehicle goes to the docking position to dock the materials to be inspected according to the instruction, and transports the materials to the test and inspection station;

[0037] S6: Testing of materials to be inspected: The testing station conducts testing of materials to be inspected according to the testing plan. After the test is completed, the material quality inspection unit sends a test completion signal to the warehouse management unit and feedbacks the test results;

[0038] S7: The inspected materials are returned to the warehouse: After receiving the signal that the test of the inspected materials is completed, the warehouse management unit issues a logistics command to the automatic conveying unit. The automatic conveying unit transports the inspected materials from the material quality inspection unit to the original storage location of the warehouse management unit according to the command; the warehouse management system changes the location status according to the test results of the inspected materials: if the test results are qualified, the location is unfrozen and the materials are ready for shipment; if the test results are unqualified, the location remains frozen, waiting for the return of the materials.

[0039] The positive effects of the present invention are:

[0040] 1. Effectively shorten the sampling inspection cycle of central warehouse materials and improve the turnover rate of central warehouse materials. For critical engineering materials, they can be inspected upon arrival, qualified upon entry into the warehouse, and usable upon exiting the warehouse, responding to engineering construction needs at the fastest speed and improving the central warehouse's material supply guarantee capabilities.

[0041] 2. The whole process of warehousing and testing of materials, i.e. arrival of goods into warehouse - sampling - inspection - testing and inspection - storage in warehouse, can be realized without human operation, thus effectively avoiding the risks brought by manual sampling and manual blind sample preparation. External factors have little influence on the random inspection of materials, thus ensuring the confidentiality and reliability of the random inspection work to the greatest extent.

[0042] 3. All links of warehousing and testing are seamlessly connected, and there is no transportation link between the storage warehouse and the testing agency, which effectively saves the cost of material sampling inspection.

[0043] 4. The data and information of each link of warehousing and testing are connected throughout the entire process, realizing the visualization and transparency of the status of materials in the warehouse.

[0044] 5. The warehouse management unit can automatically generate a sampling plan for central warehouse materials, which greatly improves the efficiency, accuracy and pertinence of plan preparation compared to manual methods.

[0045] 6. The inspection progress and results of the materials to be inspected are updated dynamically. The warehouse management unit can track and grasp the inspection progress of the materials to be inspected in real time, effectively solving the problem of uncontrollable inspection progress of the materials to be inspected.

[0046] 7. Combined with large-scale logistics and distribution enterprises, the present invention has the advantages of intensive operation of unified storage, centralized sampling, and on-demand distribution of power materials, that is, it is expanded into an integrated "storage, inspection and distribution" system, which can effectively guarantee the supply demand of key projects and critical projects.

[0059] As attached Figure 1-6 As shown, the present invention mainly includes a warehouse management unit, an automatic transportation unit, a blind sample making unit, a material quality inspection unit and a corridor, which are used to realize the automatic operation of "arrival warehousing-sampling-inspection-testing-warehousing" of power materials, that is, integrated warehousing and inspection.

[0060] After the arrival of materials, the warehousing management unit performs warehousing operations and the materials enter the warehouse for storage; the warehousing management unit determines whether the arrived materials need to be sampled and inspected based on the material inspection and test plan. If inspection is required, a sampling command is issued to the automatic transportation unit; the automatic transportation unit takes samples according to the sampling command and transports the sampled materials to the blind sample production unit; after the blind sample production unit completes the blind sample production, the automatic transportation unit transports the inspected materials through the corridor to the material quality inspection unit for testing; after the inspection is completed, the material quality inspection unit feeds back the inspection results to the warehousing management unit, and the warehousing management unit issues logistics instructions to the automatic transportation unit, which transports the inspected materials from the material quality inspection unit back to the warehouse for storage in accordance with the instructions, thereby realizing integrated automatic operation of material warehousing and inspection.

[0061] The warehouse management unit consists of a warehouse management system, a three-dimensional warehouse area, and a beam-type shelf area, and is used for storage functions such as power material storage, warehousing and inventory counting.

[0062] The warehouse management system includes warehouse business management such as material in and out of the warehouse, information flow, material information, inventory counting, warehouse management, quality inspection management, etc. Material in and out of the warehouse, information flow, material information, inventory counting, warehouse management, etc. are all existing mature technologies and will not be repeated here.

[0063] The warehouse management system is also used for information exchange between the warehouse management unit and the automatic conveying unit and the material quality inspection unit, thereby achieving coordinated interaction among warehousing, logistics and inspection services.

[0064] Quality inspection management is used for the quality and random inspection management of materials in the central warehouse, including historical database module, random inspection plan generation module and sampling module. It automatically generates random inspection plans for materials in the central warehouse and generates material sampling commands based on the inspection test plan fed back by the material quality inspection unit.

[0065] The historical database is used to store historical supply plans, historical sampling plans, historical sampling results (unqualified sampling records) and other information as benchmark data for the preparation of sampling plans.

[0066] The sampling inspection plan generation module analyzes and compares the central warehouse material supply plan with the historical database, automatically screens out the material items that need to be sampled, automatically generates a material sampling inspection plan according to the sampling inspection coverage rules and historical sampling inspection results, and sends the sampling inspection plan to the material quality inspection unit.

[0067] The sampling module samples materials according to the test plan fed back by the material quality inspection unit, using a random sampling algorithm combined with physical ID technology, determines the location of the sampled materials, and generates a sampling command.

[0068] The random sampling algorithm is a simple random non-repetitive sampling algorithm, that is, the probability of a single material meeting the sampling conditions being selected is equal.

[0069] The physical ID technology is the RFID tag and its reading device and technology, which are all existing technologies and will not be described in detail.

[0070] The material sampling inspection coverage rule means that the material sampling inspection must cover all equipment categories, all suppliers, and all supply batches. Depending on the type of materials, each type of material has different sampling quotas and coverage requirements. For example, the distribution transformer sampling inspection coverage rule is: covering all suppliers of the current year, with each supplier being sampled at least twice a year on average; the sampling ratio is 5% of the annual arrival volume or 600 units.

[0071] The three-dimensional warehouse area is used to store single equipment materials or materials that are conducive to stacking. The warehouse area is divided into heavy-duty three-dimensional shelf area and light-duty three-dimensional shelf area according to the weight characteristics of the stored materials.

[0072] like Figure 2 As shown, the heavy-duty three-dimensional shelf area consists of a group of three-dimensional shelves 1 arranged in opposite directions, which are mainly used to store materials such as 10kV distribution transformers, pole-mounted switchgear, JP cabinets, 1kV-10kV cable terminals, and 400V cable branch boxes.

[0073] The height of each layer of the three-dimensional shelf is 2000mm, and there are 4 layers in total. The shelf storage space size is W2200mm×D1300mm×H1950mm. The storage space is matched with W2000mm*D1400mm*H170mm steel pallets for material storage, and the load capacity of a single storage space is 3T.

[0074] The light three-dimensional shelf area consists of a group of three-dimensional shelves 2 arranged in opposite directions, which are mainly used to store materials such as 35kV and below current transformers, 35kV and below electromagnetic voltage transformers, 35kV and below lightning arresters, 10kV cable intermediate joints, intelligent distribution terminals, and communication ONU terminals.

[0075] The height of each layer of the three-dimensional shelf is 1550mm, there are 5 layers in total, the shelf storage space size is W1350mm×D1100mm×H1500mm, the storage space is matched with W1200mm*D1200mm*H170mm steel pallets for material storage, and the load capacity of a single storage space is 1T.

[0076] The beam-type shelf area consists of two groups of beam-type shelves 3 arranged opposite to each other, which are used to store scattered metal materials such as hardware, tower accessories, etc. When there is no vacant space in the three-dimensional warehouse area, the beam-type shelf area can also be used to store 400V cable branch boxes, JP cabinets, column switch equipment, intelligent distribution terminals, communication ONU terminals and other materials.

[0077] The height of each layer of the beam-type shelf 3 is 2000mm. There are 4 layers in total. The shelf space size is W2200mm×D1300mm×H1950mm. The space matches the W2000*D1400*H170mm pallet for material storage. The load capacity of a single space is 2T. Connecting rods are installed between two adjacent rows of shelves to connect and fix the shelves and improve the stability of the shelves. A mesh anti-skid plate is installed between the bottom beams of the space to prevent the materials in the warehouse from sliding horizontally. The mesh anti-skid plate is welded from galvanized steel bars with a diameter of 1 mm. The structure shape is as follows: Figure 3 shown.

[0078] The automatic conveying unit is composed of a warehouse control system (WCS system), a stacker 4, an AGV unmanned forklift 5, an automatic conveying line 6, and a palletizer 7. The automatic conveying unit is mainly used for material transportation within the warehouse management unit, between the warehouse management unit and the blind sample making unit, and between the material quality inspection unit, including material entry and exit, sampling of sampled materials, transportation of materials to be inspected between the warehouse management unit and the blind sample making unit, and transportation of materials to be inspected between the warehouse management unit and the material quality inspection unit through the corridor.

[0079] The AGV unmanned forklift 5 is used for transporting materials weighing less than 2 tons between the beam-type rack 3 and the conveyor line, and for transporting materials between the warehouse management unit and the material quality inspection unit.

[0080] like Figure 4As shown, the automatic conveyor line 6 is composed of a chain conveyor line 601 and a roller conveyor line 602. The chain conveyor line 601 is used for horizontal material transportation operations, and the roller conveyor line 602 is used for vertical material transportation. The horizontal direction refers to the direction parallel to the shelf, and the vertical direction refers to the direction perpendicular to the shelf. There are at least two chain conveyor lines 601 and roller conveyor lines 602, which are cross-arranged to form a closed-loop transportation of materials, so that materials can flow between various conveyor lines. One end of the chain conveyor line 601 is a material entrance 608.

[0081] On one side of the roller conveyor line 602 close to the three-dimensional storage area or the beam-type shelf area, a three-dimensional storage area docking position and a beam-type shelf area docking position 611 for the entry and exit of materials are provided. The three-dimensional storage area docking positions include a heavy-duty three-dimensional shelf area entrance docking position 609, a light-duty three-dimensional shelf area entrance docking position 610, a heavy-duty three-dimensional shelf area exit docking position 612 and a light-duty three-dimensional shelf area exit docking position 613.

[0082] The automatic conveyor line 6 is used to convey the incoming materials to the heavy-duty three-dimensional shelf area entrance docking position 609, the light-duty three-dimensional shelf area entrance docking position 610, and the beam shelf area docking position 611. The material entrance 608 of the automatic conveyor line 6 is equipped with an RFID radio frequency scanning device 604 for reading material category information.

[0083] like Figure 4 As shown, the pallet depalletizer 7 is used to place the empty pallet on the automatic conveyor line 6, and transport the empty pallet to the material entrance 608 of the automatic conveyor line 6 through the conveyor line.

[0084] The stacker 4 moves back and forth in the channel of the three-dimensional shelf. Figure 4 As shown, it is responsible for storing the materials located at the entrance docking position 609 of the heavy-duty three-dimensional shelf area and the entrance docking position 610 of the light-duty three-dimensional shelf area into the shelf positions, or taking out the materials from the shelf positions and transporting them to the exit docking position 612 of the heavy-duty three-dimensional shelf area and the exit docking position 613 of the light-duty three-dimensional shelf area.

[0085] The AGV unmanned forklift 5, automatic conveyor line 6, pallet dismantling and stacking machine 7, and stacker 4 are all existing technologies, and their structural mechanisms are not described here in detail.

[0086] The WCS system is used to coordinate and control the operation of logistics equipment such as AGV unmanned forklift 5, chain conveyor line 601, roller conveyor line 602, palletizer 7, stacker 4, etc. The WCS system exchanges information with the warehouse management unit, decomposes the warehouse management unit instructions and issues them to the designated logistics equipment respectively, and the logistics equipment completes the material transportation according to the instructions.

[0087] like Figure 4As shown, the blind sample making unit is composed of a blind sample making device 605, an air compressor 606, a label peeling machine 607, etc., and is used to realize the fully automatic blind sample making of power materials such as distribution transformers, JP cabinets, cable branch boxes, current transformers, electromagnetic voltage transformers, and pole-mounted switchgear.

[0088] The blind sample making device 605 is used for nameplate identification and positioning of materials to be inspected, label removal and labeling operations, the air compressor 606 is used for adjusting the air pressure of the label removal and labeling components of the blind sample making device, and the label peeling machine 607 is used for carrying labels.

[0089] As attached Figure 8 As shown, the blind sample making device 605 includes a blind sample making station 6001, a label picking and labeling device 6002, a moving carrier 6003, a nameplate identification device 6004 and a control cabinet 6005. The nameplate identification device 6004 obtains the nameplate information of the distribution transformer, the control cabinet 6005 issues an operation instruction, and the moving carrier 6003 carries the label picking and labeling device 6002 to complete the label picking and labeling operations. The main body of the blind sample making station 6001 is a hollow cylindrical tray, which is driven by a motor and can be rotated to realize the horizontal 360° rotation of the materials on the station, and its load is 3 tons. Since the blind sample making device 605 needs to be located on one side of the chain conveyor line 601, it can realize the blind sample making of materials during transportation. Therefore, the chain conveyor line 601 at the position corresponding to the blind sample making device 605 is disconnected, and the blind sample making station 6001 is located at the disconnected position of the chain conveyor line 601. A conveyor chain is arranged on the pallet, and when the pallet rotates to a certain position, the two ends of the conveyor chain are opposite to the two ends of the disconnected chain conveyor line 601, so that the materials can pass through the blind sample making work 6001 smoothly.

[0090] The moving carrier 3 adopts a flexible six-axis robotic arm, which is arranged on one side of the blind sample making station 6001. The label picking and labeling device 6002 and the nameplate identification device 6004 are both arranged at the end of the flexible six-axis robotic arm. The flexible six-axis robotic arm drives the label picking and labeling device 6002 and the nameplate identification device 6004 to realize multi-degree-of-freedom movement, thereby performing nameplate identification and label picking and labeling actions.

[0091] The control cabinet 6005 is the signal processing terminal of the blind sample making device, which is used for receiving signals and issuing operation commands. After receiving the material in place signal, the control cabinet 6005 issues instructions to the designated components to control the blind sample making station 6001, the moving carrier 6003, the labeling device 6002, the nameplate identification device 6004 and other components to perform the blind sample making operation.

[0092] The flexible six-axis robot arm receives the signal from the control cabinet and is equipped with a label picking and labeling device 6002 and a nameplate recognition device 6004 to complete the nameplate recognition, label picking and labeling actions.

[0093] As attached Figure 9-12 As shown, the labeling device 6002 includes a sponge suction cup 205 connected to an air compressor 606, which is used to absorb the label and attach the label to the material. The air compressor is used to generate negative pressure in the cavity of the sponge suction cup 205, so that the sponge suction cup completes the labeling operation through the air pressure difference principle. The sponge suction cup 205 is provided with a negative pressure sensor 207 for monitoring the air pressure state inside the sponge suction cup 205, and the air pressure of the labeling process is monitored. At the same time, a throttle valve for adjusting the air pressure inside the sponge suction cup 205 is also provided on the pipeline between the sponge suction cup 205 and the air compressor, and the air pressure inside the sponge suction cup 205 is controlled to allow the label to be absorbed.

[0094] There are three hole structures on the left and right sides of the sponge suction cup 205 (i.e., the narrow surface of the sponge suction cup 205) respectively. Among the three holes on one side, one is the installation hole of the negative pressure sensor 207, and two are exhaust holes; among the three holes on the other side, one is the throttle valve connecting hole 206, and two are exhaust holes.

[0095] As a further improvement, the labeling device 6002 further includes a housing 203 and a pressure sensor 202 disposed on the bottom plate of the housing 203. The bottom plate of the sponge suction cup 205 is connected to the upper end of the connecting rod 204, and the lower end of the connecting rod 204 is disposed on the pressure sensor 202 through a pressure sensing platform. A six-axis flange 201 is disposed on the outer side of the bottom of the housing 203 for connecting to the end of the flexible six-axis robot arm.

[0096] The pressure sensing platform includes a connecting plate 212, a top plate 208, a sleeve 213 and a support rod 214. The top plate 208 is located above the connecting plate 212 and a plurality of sleeves 213 are evenly arranged between the two. Bolts are inserted into the sleeves 213 to achieve the fixation between the connecting plate 212 and the top plate 208. There are two support rods 214, which are symmetrically arranged below the connecting plate 212. There are also two corresponding pressure sensors 202, which are symmetrically arranged below the support rods 214. The bottom ends of the support rods 214 are mounted on the corresponding pressure sensors 202. The lower ends of the connecting rods 204 pass through the top plate 208 and are fixedly connected to the connecting plate 212.

[0097] The pressure sensing platform is used to fix the connecting rod 204 and transmit the force from the connecting rod 204 to the two pressure sensors 202. When the forces on the two pressure sensors 202 are inconsistent, the robot arm adjusts the state of the labeling device to make the connecting rod 204 perpendicular to the sponge suction cup bottom plate so that the label is evenly attached to the nameplate.

[0098] As attached Fig.10 and 11As shown, the top of the connecting rod 204 is movably connected to the sponge suction cup 205, so that the sponge suction cup 205 can rotate on the connecting rod 204. In order to limit the sponge suction cup 205 to a certain extent, a spring 209 is installed between the four sides of the sponge suction cup 205 and the top plate 208, so that the sponge suction cup 205 can form a certain angle with the connecting rod 204 when subjected to force, and when not subjected to external force, under the action of the spring 209, it returns to the initial position, that is, the position where the connecting rod 204 and the sponge suction cup 205 are perpendicular.

[0099] As attached Fig.11 , 12 As shown, in order to make the sponge suction cup 205 movably connected to the connecting rod 204, a concave connecting block 210 adapted to the top of the connecting rod 204 is provided at the bottom of the sponge suction cup 205, the top of the connecting rod 204 is inserted into the concave connecting block 210, and then the two are connected by a pin shaft, so that the sponge suction cup 205 can realize 180° rotation on the connecting rod 204.

[0100] As for those skilled in the art, they should know that when the sponge suction cup 205 needs to move more freely, the connection structure can be changed to a universal ball head, so that the sponge suction cup 205 can be rotated in multiple directions.

[0101] The housing 203 is a square structure, welded from T2 stainless steel plates, with a smooth surface, and is used to protect the pressure sensor 202, ensuring that the pressure sensing result is not disturbed and preventing the pressure sensor result from being affected by external factors. A circular hole is opened on the side plate of the housing 203 for leading out the power line of the pressure sensor 202, and the position of the hole is determined according to the layout of the power line. Fig.10 As shown, the nameplate recognition device 4 is used to identify and locate the nameplate information of the distribution transformer, including a laser rangefinder 401 and an industrial camera 402 arranged on one side of the housing 203. After the distribution transformer is in place, the laser rangefinder 401 emits a laser signal to obtain the vertical distance information of the nameplate, that is, the Z-axis coordinate; the industrial camera 402 scans the plane where the nameplate is located to obtain the plane position information of the nameplate, that is, the X-axis and Y-axis coordinates, and the three-dimensional coordinate information of the nameplate is transmitted to the control cabinet 5 through PLC communication.

[0102] When in use, the moving carrier 6003 carries the nameplate recognition device 6004 to scan the distribution transformer and obtain the nameplate position information. The laser rangefinder 401 emits a laser signal to obtain the vertical distance information of the nameplate, i.e., the Z-axis coordinate. The industrial camera 402 scans the plane where the nameplate is located to obtain the plane position information of the nameplate, i.e., the X-axis and Y-axis coordinates.

[0103] The robotic arm is equipped with a label picking and labeling device 6002 to complete label picking: the front end of the robotic arm is connected to the label picking and labeling device 6002 through a six-axis flange to form a linkage mechanism; the robotic arm is equipped with a label picking and labeling device 6002, which rotates to a fixed label picking position, and the label picking and labeling device 6002 contacts the label to form a temporary enclosed space, and the air in the enclosed space is pumped out through a pneumatic pipeline to form an air pressure difference, so that the label and the sponge suction cup 205 are squeezed together to complete the label picking action. Because the negative pressure in the sponge suction cup 205 will change before and after the label is sucked, the negative pressure monitoring condition of the negative pressure sensor 207 is used to determine whether the label is sucked.

[0104] After the nameplate recognition device 6004 obtains the nameplate position information, the label picking and labeling device 6002 absorbs the label, and the robotic arm carrying the label picking and labeling device 6002 moves to the center of mass of the nameplate, so that the label on the sponge suction cup 205 contacts the nameplate, and the air compressor breaks the negative pressure to make the label attached to the nameplate of the distribution transformer; according to the monitoring value of the negative pressure sensor 207, it is determined whether the label attachment is completed; if the value shows that it is completed, the blind sample making device is reset, if the value shows that it is not completed, the labeling action is repeated until the labeling action is determined to be completed.

[0105] After the materials for inspection arrive at the blind sample making unit, the blind sample making device identifies the nameplate. After obtaining the nameplate location information, the blind sample making device 605, the air compressor 606, and the label peeling machine 607 cooperate to perform label removal and labeling operations. After the blind sample making is completed, the blind sample making device control cabinet sends a completion signal to the automatic conveying unit, and the automatic conveying unit conveys the materials for inspection that have completed the blind sample making to the material quality inspection unit through the corridor.

[0106] The material quality inspection unit is used to carry out testing of materials to be inspected. The unit is mainly composed of a testing system, a transportation system, a security system, and a central control system. The testing system is used to carry out testing of materials to be inspected, the transportation system is used for the internal logistics transportation of materials to be inspected in the material quality inspection unit, the security system is used for safety protection during the testing of the testing system, and the central control system is used for the coordination, management and control of the subsystems of the entire material quality inspection unit and between the subsystems, as well as the information exchange between the material quality inspection unit and the storage management unit.

[0107] The test and inspection system consists of inspection stations, which are built according to the types of materials to be inspected, such as Figure 5As shown, a single inspection station is mainly composed of a human-machine interaction terminal 4 and a test device. The test device highly integrates all the equipment and functions required for the test, such as test power supply, control circuit, display, measurement, etc., and is divided into intelligent measurement module, test power supply module, power distribution module, and automatic switching line module according to modular design management. The human-machine interaction terminal is a touch screen, which is used to view and display test conditions such as test wiring, test items and progress, test duration, etc., and can also be used for manual emergency stop test.

[0108] The intelligent testing device has good functional expandability and can expand testing capabilities by adding or changing modules.

[0109] When the materials to be inspected arrive at the testing station and the test wiring is completed correctly, the test detection system can realize one-click automatic detection according to the test plan, that is, automatically generate the test plan, automatically control the process, automatically switch the test wiring, and automatically test the test. After the inspection is completed, the test report is automatically generated. Compared with the traditional manual inspection method, there is no need to manually select test items, adjust the test wiring, replace the test equipment, and prepare the test report. It has the characteristics of intelligence and automation, and the inspection efficiency is greatly improved.

[0110] The transportation system is mainly composed of AGV transport vehicles, charging facilities, and tracking navigation lines. The tracking navigation lines, AGV transport vehicles, and charging facilities are all existing technologies and will not be described in detail here.

Safety doors and safety gate control 12 are installed on the inlet and outlet passage 10 and the material inlet and outlet passage 9. The safety gate control 12 includes a gate control sensor and an audible and visual warning light.

[0112] The intelligent safety fence 8 is informationally interconnected with the test and detection system and the transportation system to achieve functional linkage. The system automatically opens and closes the safety door when the AGV transport vehicle enters and exits the detection station. During the test at the detection station, the safety fence 8 is in a fully enclosed state. When someone breaks through the safety fence 8, the power supply of the detection station can be quickly disconnected, the sound and light warning lights alarm, and the abnormal situation is automatically reported to the central control system.

[0113] The video monitoring system adopts an IP digital monitoring system and uses the existing TCP / IP network technology to conduct remote image monitoring of public pedestrian passage areas, test and inspection areas, central control room and other areas within the material inspection unit.

[0114] The intelligent voice system is a public broadcasting system with a partition broadcasting function. It can intelligently play the inspection station status information, test prompts, completion status, and fault information according to the operating conditions of each inspection station.

[0115] The central control system is mainly composed of a central console, display screen, data processor, UPS power supply, laser printer and other equipment, all of which are existing technologies and will not be described in detail here. The central control system includes test and inspection management module, logistics turnover control module, data collection and monitoring module, data analysis and processing module, task planning management and other functional modules. Through the integrated platform control method, it realizes the refined management of each subsystem of the material quality inspection unit, as well as the coordinated management and control between each subsystem.

[0116] The test and inspection management module is used for test plan and progress management, test report management, and historical data query. This module is used to exchange data information with the warehouse management unit and the test and inspection system. This module is used to receive the material sampling plan sent by the warehouse management unit, convert the sampling plan into a material quality inspection unit test plan and issue it to the test and inspection system. The data collection and monitoring module is used to collect the test progress information of each inspection station, and provide real-time feedback on the execution of the sampling plan to the warehouse management unit, including the number and details of the completed plan, the number and details of the plan under inspection, the number and details of the plan that has not been implemented, the test results of the completed plan, and the test progress of a single ongoing plan.

[0117] The logistics turnover control module generates logistics dispatch instructions based on the inspection test plan and the status of the inspection station and issues them to the AGV transport vehicle to realize the logistics turnover of the inspected materials within the material quality inspection unit.

[0118] The data acquisition and monitoring module is used to collect the test progress information of each testing station and the environmental temperature, humidity, and atmospheric pressure data, and to monitor the execution of the testing tasks and the environmental conditions in real time.

[0119] The data analysis and processing module is used for test and inspection data analysis and statistical analysis of the distribution of qualified rates of different equipment types and different test items, and automatically generates reports.

[0120] like Figure 6 As shown, the corridor is a dedicated logistics channel between the storage management unit and the material quality inspection unit. The corridor is a fully enclosed structure that can avoid the impact of weather factors on logistics operations. Automatic conveyor lines, automatic elevators and other transportation equipment can be installed inside the corridor to realize material transportation; AGV unmanned forklifts 5 can also carry the materials to be inspected and transport them to the material quality inspection unit through the corridor.

[0121] As attached Figure 7 The integrated method for storage and inspection of electric power materials shown in the figure comprises the following steps:

[0122] S1: Generate material sampling test plan: After the central warehouse material procurement contract is signed, the material supply plan is generated. After the warehouse management system generates the material sampling plan based on the material supply plan, the sampling plan is pushed to the central control system of the material quality inspection unit. The central control system generates the inspection test plan and feeds the inspection test plan back to the warehouse management system.

[0123] After the material supplier completes the material production preparation according to the material supply plan and meets the delivery conditions, he / she shall submit the material warehousing appointment application to the warehouse management unit. The warehouse management unit shall review the warehousing appointment application and feedback the specific warehousing time to the material supplier after the review is passed. The supplier shall deliver the goods according to the date.

[0124] S2: Confirmation and warehousing of arrived materials: After the materials arrive at the central warehouse, the delivery vehicle passes through a channel equipped with a radio frequency scanning device, reads the RFID tag information of the materials and sends it to the warehouse management system to confirm the arrived material information. The material information includes equipment type, basic information, and quantity. After the materials are confirmed, the warehouse management system sends the warehouse location information to the WCS system and sends the material warehousing instruction to the WCS system based on the material information obtained by scanning.

[0125] The WCS system receives and decomposes the warehousing command, and issues instructions to the AGV unmanned forklift 5, the automatic conveyor line 6, the palletizer 7, and the stacker 4 to transport the materials to the designated warehouse. After the materials enter the warehouse, the WCS system sends a signal that the materials are completed.

[0126] S3: Material sampling: After all the incoming materials are put into storage, the warehouse management system determines whether the new incoming materials need to be sampled according to the material sampling plan. If the incoming materials need to be sampled, the warehouse management system freezes and locks the new incoming warehouse. The warehouse management system sends a sampling command to the automatic conveying unit according to the inspection and test plan, and the automatic conveying unit transports the sampled materials to the blind sample making station for blind sample making.

[0127] S4: Blind sample preparation of materials to be inspected: After the materials to be inspected arrive at the blind sample preparation station, the blind sample preparation device scans and obtains the nameplate location of the materials to be inspected. After obtaining the nameplate location information, the blind sample preparation device, the air compressor 606, and the label peeling machine 607 work together to perform label removal and labeling operations.

[0128] S5: Blind sample inspection: After the blind sample production of the materials to be inspected is completed, the warehouse management unit sends a logistics signal to the material quality inspection unit, and the automatic conveying unit transports the materials to be inspected to the docking position of the material quality inspection unit through the corridor; after the material quality inspection unit receives the logistics signal from the warehouse management unit, it generates a logistics dispatch instruction and issues it to the AGV transport vehicle according to the type of materials to be inspected and the status of the test and inspection station. The AGV transport vehicle goes to the docking position to dock the materials to be inspected according to the instruction, and transports the materials to the test and inspection station.

[0129] S6: Testing of materials submitted for inspection: The testing station conducts testing of materials submitted for inspection according to the testing plan. After the test is completed, the material quality inspection unit sends a test completion signal to the warehouse management unit and feeds back the test results.

[0130] S7: The inspected materials are returned to the warehouse: After receiving the signal that the inspection materials have been tested, the warehouse management unit issues a logistics command to the automatic conveying unit, which transports the inspected materials from the material quality inspection unit to the original storage location of the warehouse management unit according to the command. The warehouse management system changes the location status according to the test results of the inspected materials: if the test results are qualified, the location is unfrozen and the materials are ready for shipment; if the test results are unqualified, the location remains frozen and the materials are waiting for return or exchange.

The stacker 4 conveys the distribution transformer to the designated storage location. After the distribution transformer enters the storage location, the WCS system sends a distribution transformer storage completion signal to the warehouse management system. After all the arrived distribution transformers are stored, the warehouse management system freezes and locks the storage location of the newly arrived distribution transformer. The warehouse management system determines whether the newly arrived distribution transformer needs to be sampled according to the material sampling plan. If the arrived distribution transformer does not need to be sampled, the storage location of the newly arrived distribution transformer is unfrozen and waits for delivery.

After the test is completed, the material quality inspection unit sends a test completion signal to the warehouse management unit and feedbacks the test situation. After receiving the distribution transformer test completion signal, the warehouse management unit issues a logistics command to the automatic conveying unit. The automatic conveying unit transports the distribution transformer from the material quality inspection unit back to the original storage position of the warehouse management unit according to the command. The warehouse management unit changes the position status according to the test results of the distribution transformer: if the test results are qualified, the position of the distribution transformers arriving in the same batch is unfrozen and waits for delivery; if the test results are unqualified, the position of the distribution transformers arriving in the same batch is still frozen and waits for the supplier to return or exchange the goods.
