Description

Technical Field

[0001] The present invention relates to the technical field of warehouse management and scheduling, and in particular to an automatic feeding method, device, system and equipment for a metering instrument stereoscopic warehouse. Background Art

[0002] The measuring instrument high-bay warehouse is generally composed of shelves, aisles and stackers. The shelves are divided into many cargo spaces for storing measuring instruments. The stacker is responsible for taking out a stack of measuring instruments from the cargo space and placing it on the conveyor track (outbound), or storing a stack of measuring instruments on the track in the cargo space (inbound). Due to the design of multiple aisles and multiple stackers, the high-bay warehouse has the ability to handle multiple inbound and outbound tasks in parallel.

[0003] When multiple calibration tasks or delivery tasks are carried out at the same time, the maximum parallel delivery capacity of the vertical warehouse may be exceeded. At this time, the vertical warehouse cannot meet the material requirements of all calibration / delivery tasks at the same time. Therefore, the vertical warehouse delivery scheduling program needs to solve the problem of when the vertical warehouse should deliver which measuring instruments to which demand entity. In order to ensure that the material requirements of all demand entities can be maximized within the capacity of the vertical warehouse, a reasonable scheduling model needs to be designed to solve this problem.

[0004] The processing flow of the existing technology: Material application form generation program: regularly traverse all demand entities, obtain the current material demand of each entity, and generate a material application form based on the demand. Usually, one material application is generated for one unit of demand and placed in the material application queue; Material application form processing program: according to the concurrent outbound storage capacity of the vertical warehouse, regularly take out a fixed number of material application forms from the material application queue, generate outbound tasks, send them to the vertical warehouse, and the vertical warehouse is responsible for outbound storage. For demand entities with buffers, the current demand is equal to the number of available positions in the buffer; for demand entities without buffers, the current demand is a fixed value; The frequency of the scheduled execution of the material application form processing program should be adjusted according to the time consumption of outbound storage in the vertical warehouse, and try to ensure that outbound tasks are not accumulated in the vertical warehouse.

[0005] The existing technology feeds materials according to the demand of the demand subject, but cannot realize scheduling according to the urgency of the demand of the demand subject, resulting in some demand subjects not feeding materials in time for a period of time, resulting in idleness / idling problems, affecting the overall production efficiency. In addition, since the material application form processing program cannot sense when the vertical warehouse completes a certain outbound task, in extreme cases, too many outbound tasks will be sent to the vertical warehouse, resulting in accumulation.

[0029] It should be understood that the order of execution of the steps in the following embodiments does not imply a precedence of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0030] Measuring instruments are instruments or equipment specifically used to measure electrical quantities such as electrical energy, voltage, current, power, etc. in power systems. They are widely used in power plants, substations, transmission and distribution lines, user terminals, and other links to ensure accurate measurement, safe, reliable, and efficient operation of power supply.

[0031] Measuring instrument vertical warehouse (hereinafter referred to as vertical warehouse or vertical warehouse) refers to an automated storage system used to store, manage and automatically handle measuring instruments (such as electric energy meters, current transformers, voltage transformers, etc.). This type of warehouse uses advanced logistics technology and equipment to achieve efficient and accurate management of measuring instruments. It is suitable for power companies, metering centers and other occasions that require large-scale storage and frequent warehousing operations.

[0032] The measuring instrument high-bay warehouse is generally composed of shelves, aisles and stackers. The shelves are divided into many cargo spaces for storing measuring instruments. The stacker is responsible for taking out a stack of measuring instruments from the cargo space and placing it on the conveyor track (outbound), or storing a stack of measuring instruments on the track in the cargo space (inbound). Due to the design of multiple aisles and multiple stackers, the high-bay warehouse has the ability to handle multiple inbound and outbound tasks in parallel.

[0033] The calibration of measuring instruments is the responsibility of the calibration line. After the vertical warehouse takes out the measuring instruments (in stacks), the measuring instruments are transported to the calibration line through the conveyor track. The calibration line completes the calibration test of the measuring instruments. In order to improve the efficiency of the vertical warehouse feeding, the calibration line is generally designed with a buffer device to buffer (in stacks) the measuring instruments delivered.

[0034] For distribution outbound, after the vertical warehouse takes out the measuring instruments (in stacks), they are transferred to the corresponding platform via the conveyor track, and the loaders waiting at the platform load the measuring instruments onto the transport vehicle.

[0035] Since the vertical warehouse (warehouse management software) is only responsible for receiving outbound tasks and operating the stacker to deliver the measuring instruments specified in the outbound tasks to the specified demand entities (calibration lines or platforms), the vertical warehouse itself cannot decide which measuring instruments need to be delivered to which demand entities. These are achieved by the scheduling program.

[0036] The measuring instrument verification system is an industrial automation assembly line system composed of various types of automation equipment (including conveyor belts, various processing units and distribution equipment, etc.) and software systems for production control, which is used to complete the accuracy verification and calibration of measuring instruments (including electric energy meters, low-voltage current transformers, etc.). The system can automatically receive various types of measuring instruments from the storage system through the conveyor belt, and then complete the verification and calibration work, and finally transport the verified and calibrated measuring instruments to the storage system. The measuring instrument verification scheduling algorithm described in the present invention mainly solves the logistics buffer balance problem involving multiple sets of measuring instrument verification systems running simultaneously.

[0037] The measuring instrument storage system is a set of hardware systems consisting of various types of automated equipment (including three-dimensional shelves, aisle-type lifting loaders, and powered roller conveyors) and a storage and warehousing control software system. It is an industrial three-dimensional warehouse system used to complete the warehousing, storage, and outbound of measuring instruments. The system can complete the transportation of measuring instruments inside and outside the warehouse and between the measuring instrument calibration system through powered roller conveyors, and complete the transportation between the warehouse and shelves through aisle-type lifting loaders.

[0038] The consumer system takes out materials (consumes) from the material buffer and then performs verification and calibration. The main responsibility of the consumer system is to continuously consume materials and suspend consumption when the material buffer is empty until new materials are available. In the present invention, the consumer system mainly refers to multiple sets of measuring instrument verification systems.

[0039] The producer system continuously outputs materials (production) to the material buffer of the consumer system for consumption by these systems. In the present invention, in order to ensure the continuity and stability of material output and to ensure that there are enough materials in the buffer of each production system for the consumer system, the producer system needs to complete the relevant operations under the scheduling of the host system. The producer system in the present invention mainly refers to the metering instrument storage system.

[0040] The host system mainly refers to the software function module developed using the metrological instrument calibration scheduling algorithm described in the present invention. The main goal of the host system is to ensure that the material buffers of multiple consumer systems can meet their consumption needs. To achieve this goal, the host system needs to schedule the producer system (metrological instrument storage system) to transport the materials to the material buffers of different consumer systems (metrological instrument calibration systems) according to different materials, different cycles, and different quantities.

[0041] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0042] The first embodiment of the present invention provides an automatic feeding method for a metering instrument stereoscopic warehouse, which can be applied to Figure 1In the application environment, the client communicates with the server. The client includes but is not limited to PDAs, desktop computers, laptops, ultra-mobile personal computers (UMPCs), netbooks, cloud terminal devices, personal digital assistants (PDAs), and other terminal devices. The server can be implemented with an independent server or a server cluster consisting of multiple servers.

[0043] See also Figure 2 , is a flow chart of an automatic feeding method for a metering instrument stereoscopic warehouse provided by the first embodiment of the present invention. The automatic feeding method for a metering instrument stereoscopic warehouse can be applied to Figure 1 The client in the client, the terminal device corresponding to the client connects to the target database through the preset application programming interface (API). When the target data is driven to execute the corresponding task, the corresponding task log will be generated, and the above task log can be collected through the API. Figure 2 As shown, the automatic feeding method of the measuring instrument stereoscopic warehouse includes the following steps: S101: Circularly monitor the usage of the buffer corresponding to the material demand subject and calculate the buffer hunger degree; if the buffer hunger degree meets the set conditions, initiate a material demand application form and add it to the material application queue.

[0044] Each demand subject corresponds to a logical buffer. The logical buffer is a program that is responsible for cyclically monitoring the usage of the demand subject's buffer (physical buffer or virtual buffer) and calculating the buffer hunger degree. If the hunger degree is greater than 0, a demand application form is initiated to the material application queue. Otherwise, the cyclic monitoring continues until the demand subject completes the task.

[0045] S102: Obtain a material demand application form from the material application queue; apply for a token from the token center; if the token application is successful, generate a delivery task and send it to the three-dimensional warehouse; when the three-dimensional warehouse completes the delivery, release the token.

[0046] The token center initializes a fixed number of tokens (the total number of tokens is determined by the concurrent outbound capacity of the library). The material application form is obtained from the material application queue in a loop (acquired according to the real-time hunger degree), and then the token center is applied for a token. If the application is successful, the corresponding outbound task is generated and sent to the library, which is responsible for executing the outbound. After the library completes the outbound, it will notify the scheduler, which is responsible for releasing the token.

[0047] The automatic feeding method of the measuring instrument three-dimensional warehouse of the present embodiment monitors the usage of the buffer zone corresponding to the material demand subject in a loop and calculates the hunger degree of the buffer zone; if the hunger degree of the buffer zone meets the set conditions, a material demand application form is initiated and added to the material application queue; the material demand application form is obtained from the material application queue; a token is applied for from the token center; if the token application is successful, an outbound task is generated and sent to the three-dimensional warehouse; when the three-dimensional warehouse completes the outbound delivery, the token is released; thereby, the material demand quantity and demand urgency of the material demand subject are perceived and calculated in real time, and a material application is initiated, and the outbound delivery of the three-dimensional warehouse is scheduled according to the demand urgency, and the outbound delivery capacity of the three-dimensional warehouse is preferentially allocated to the demand subject with the current high urgency; the outbound delivery efficiency of the measuring instrument three-dimensional warehouse is improved, thereby improving the efficiency of the calibration, testing and distribution of the measuring instruments of the metrology and inspection center; so that the demand subject of each task can obtain the most sufficient material supply, thereby maximizing the time value.

[0048] The present invention completes the orderly supply of different measuring instruments (electricity meters, mutual inductors, etc.) from the measuring instrument storage system to the measuring instrument calibration system according to the actual execution process of the measuring instrument calibration business and the requirements of the production rhythm. The material transportation scheduling of different measuring instruments between different multiple calibration systems and storage systems is realized. Compared with the prior art, the present invention completes the transportation scheduling of materials between multiple calibration systems and a single storage system, and realizes the balanced allocation of materials between multiple systems.

[0049] The communication method between the host system and the consumer system of the present invention does not adopt communication based on the hardware level, but is based on the communication at the software level of both systems. This method is compatible with both active hunger information acquisition and passive hunger information acquisition methods. The active hunger information acquisition method is to initiate an active polling call to the consumer system to obtain its free material buffer. The passive hunger information acquisition is to initiate a free material buffer information feedback call initiated by the consumer system to the host system described in this patent when a relevant event of the consumer system is triggered. In the prior art, a common form is a method of obtaining hunger information based on the hardware level. That is, the hunger level is obtained by a physical sensor deployed in the consumer system, and then communicates with the host system through relevant channels, and the acquisition method is passive acquisition.

[0050] On the basis of the above embodiment, optionally, the automatic feeding method of the metering instrument stereoscopic warehouse calculates the hunger degree of the buffer zone through the following steps: S201, calculating the buffer hunger degree according to the buffer capacity, the number of applications and the number of uses; the number of applications is the number of materials that have been applied for but not received; the number of uses is the number of locations currently used in the buffer.

[0051] Assume that all material demand entities have buffers. For demand entities without physical buffers, we introduce virtual buffers (buffer capacity is 1, such as demand entity C (transport vehicle) in the design scheme flowchart).

[0052] Buffer capacity (cap): the total number of available positions in the buffer; Applied: The number of materials that have been applied for but not received. Used: The number of locations currently used by the buffer; hungerSpeed: 1 / time (in seconds) for the buffer hunger to change from 0 to 100.

[0053] The hunger level of the buffer is used to indicate the demand for materials by the demand subject, and its value is [0, 100]. When the hunger level is 0, it means that the demand subject does not need materials at this time. When the hunger level is 100, it means that materials must be obtained at present, otherwise the demand subject will be idle / idling. The calculation formula of the current hunger level of the buffer is as follows: hungerLevel = (cap - applied - used) *100 / cap Based on the above embodiment, optionally, obtaining a material demand application form from a material application queue in the automatic feeding method of a measuring instrument stereoscopic warehouse includes: S301, obtaining the material demand application form with the highest real-time hunger from the material application queue.

[0054] On the basis of the above embodiment, optionally, the step of calculating the real-time hunger degree in the automatic feeding method of the metering instrument stereoscopic warehouse includes: S401, calculating a first time difference according to the initiation time of the material application form and the current time.

[0055] S402, calculating a progressive hunger degree according to the first time difference and the hunger speed of the buffer zone.

[0056] S403, obtaining the real-time hunger degree of the material requisition form according to the progressive hunger degree and the hunger degree at the time of initiation.

[0057] Request subject ID (subjectId): Identifies the request subject that initiates the material application.

[0058] Start Time (startTime): The start time of the material application.

[0059] Current time (currentTime): The current time of the system.

[0060] StartHungerLevel: The hunger level of the main demand buffer at the time of initiation.

[0061] Buffer hunger speed (hungerSpeed): The hunger speed of the demand subject buffer.

[0062] The material application queue is a dynamic priority queue based on real-time hunger level, that is, each time the material application form with the highest real-time hunger level is obtained from the queue. The real-time hunger level (realtimeHungerLevel) is calculated as follows: realtimeHungerLevel = startHungerLevel + (currentTime - startTime)*hungerSpeed Among them, the first time difference is currentTime - startTime, and the progressive hunger degree is (currentTime -startTime) * hungerSpeed.

[0063] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0064] Corresponding to the method of the above embodiment, Figure 3 The structural block diagram of the automatic feeding device for a three-dimensional warehouse of measuring instruments provided by an embodiment of the present invention is shown. The automatic feeding device for a three-dimensional warehouse of measuring instruments is applied to a computer device, and the computer device is connected to a target database through a preset application program interface. When the target database is driven to execute a corresponding task, a corresponding task log is generated, and the task log can be collected through the API. For the convenience of explanation, only the part related to the embodiment of the present invention is shown.

[0066] The material outbound module 502 is used to obtain the material demand application form from the material application queue; apply for a token from the token center; if the token application is successful, generate an outbound task and send it to the three-dimensional warehouse; when the three-dimensional warehouse completes the outbound, release the token.

[0067] Optionally, the material demand application module in the above-mentioned measuring instrument stereoscopic warehouse automatic feeding device calculates the buffer hunger degree based on the buffer capacity, application number and usage number; the application number is the number of material applications that have been initiated but not received; the usage number is the number of positions currently used in the buffer.
