Description

Technical Field

[0001] The present invention relates to the technical field of vertical warehouses, and in particular to a multi-storage location detection method for vertical warehouses. Background Art

[0002] In modern logistics systems, stereoscopic warehouses (vertical warehouses) are widely used in various industrial and commercial fields as an efficient and automated warehousing solution. It significantly improves storage density and material handling efficiency through the use of vertical space. However, with the increase in the types of stored items and the improvement of storage environment requirements, how to effectively manage and control the environmental conditions of each storage location in the vertical warehouse has become a key issue. Large vertical warehouses will have hundreds or thousands of storage locations. If a distributed system is used to collect data signals, there will be a large control cost.

[0003] The invention patent with application number 201910692058.X discloses a storage location detection system, which can scan multiple storage locations at a limited cost. However, due to the power consumption of sensors and PLC inputs, the invention can only detect a large number of storage locations by increasing the number of output points when there are many storage locations. In addition, this method will increase the number of output points, which will increase the storage location scanning time and waste a lot of electricity. Summary of the invention

[0004] The purpose of the present invention is to provide a method for detecting multiple storage locations in a vertical warehouse to solve the following technical problems:

[0005] In the case of low cost, due to the limited PLC input interface, it is impossible to detect the presence or absence of material information in hundreds to thousands of storage locations.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A method for detecting multiple storage locations in a vertical warehouse comprises the following steps:

[0008] The environmental indicators of each storage location in the vertical warehouse are collected through sensors, and the matrix-specified scanning mode is adopted. The designated scanning is performed when the vertical warehouse is initialized, when the corresponding storage location of the vertical warehouse is used, and when the host computer needs to obtain the information of a certain storage location;

[0009] Obtain the types of items to be stored in the warehouse and the appropriate range of environmental indicators corresponding to each item type, determine whether there is an intersection between the appropriate ranges of environmental indicators of different items, place the items with intersections in adjacent storage locations, mark them as storage location groups, centrally control the environmental indicators of the storage location groups, and mark the intersection as the environmental indicator setting range of the storage location group;

[0010] For items that do not have an intersection, each item is placed in a separate storage location, and the appropriate range of environmental indicators for each item is set to the environmental indicator setting range of the storage location;

[0011] The real-time environmental index of each storage location is detected every unit period; the real-time environmental index is compared with the environmental index setting interval of the storage location, and when the real-time environmental index exceeds the interval, the corresponding environmental index type is adjusted.

[0012] As a further solution of the present invention: the PLC is driven by an external intermediate relay, and the intermediate relay is placed near the library sensor.

[0013] As a further solution of the present invention: the single-line scanning time of the vertical library is set to 1 second, of which 0.6 seconds is used to start the relay and scan, and 0.4 seconds is used to close the relay for system discharge.

[0014] As a further solution of the present invention: when the vertical warehouse is initialized, all storage locations of the entire vertical warehouse are scanned, and the scanning time is n*1 second, which is the number of PLC output points corresponding to the vertical warehouse.

[0015] As a further solution of the present invention: when the stacker or robot needs to store or retrieve materials at a certain storage location, the vertical warehouse scans the corresponding storage location separately; when the host computer needs to obtain information about a certain storage location, the vertical warehouse scans the corresponding storage location separately. When the vertical warehouse does not perform storage location material detection, the vertical warehouse is in standby mode.

[0016] As a further solution of the present invention: the environmental indicators include but are not limited to temperature, humidity and illumination, and the sensors include but are not limited to temperature sensors, humidity sensors and photoelectric sensors.

[0017] As a further solution of the present invention: for any pair of different types of items to be stored, obtain the environmental indicator suitable interval A and environmental indicator suitable interval B of the corresponding multiple indicators, perform intersection operation on the single suitable interval of the single indicator respectively, obtain several sub-intersections, and use the set of sub-intersections as the environmental indicator setting interval for the items to be stored.

[0018] As a further solution of the present invention: the PLC is also used to receive environmental indicator data collected by sensors. When any real-time environmental indicator exceeds a set range, the PLC controls the corresponding indicator actuator to make adjustments so that the environmental indicator returns to an appropriate range.

[0019] As a further solution of the present invention: the types of items stored in each storage location are collected and assigned corresponding weights, and the corresponding environmental indicator detection cycle is set according to the value of the weight.

[0020] As a further solution of the present invention: the opening and closing status, storage status and real-time environmental indicators of the storage location are displayed through a human-computer interaction page. When the environmental indicators exceed the preset range or the storage location fails to open or close, an alarm signal is immediately issued to remind the operator to take corresponding measures.

[0021] Beneficial effects of the present invention:

[0022] The present invention ensures that different items are stored in the most suitable environment through precise environmental control and classified storage of items, thereby reducing the risk of item damage. Centralized control of item storage locations with similar environmental requirements reduces energy waste and achieves efficient use of resources. The design of matrix-specified scanning mode and intermediate relay-driven PLC shortens the scanning time and improves the response speed of the system. Utilizing sensor data and PLC control, automatic adjustment of environmental indicators is achieved, reducing the burden of manual operation. According to the importance and sensitivity of the items, the detection cycle is dynamically adjusted to ensure stricter environmental monitoring of key items. The human-computer interaction page provides intuitive information display and alarm functions, which are convenient for operators to monitor and manage. The flexibility of the design of the present invention allows the method to be easily integrated with other logistics management systems, while supporting future technology upgrades and expansions. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 As shown, the present invention is a method for detecting multiple storage locations in a vertical warehouse, comprising the following steps:

[0027] 1. Sensor deployment and data collection:

[0028] Install multiple sensors at each storage location, such as temperature, humidity, light, air quality, etc., to monitor environmental conditions in real time.

[0029] Using Internet of Things (IoT) technology, sensor data is transmitted to a central control system in real time.

[0030] 2. Matrix specified scanning mode:

[0031] Based on intelligent scanning algorithms, key storage locations are scanned first according to the storage frequency and importance of items.

[0032] When the warehouse is initialized, a comprehensive scan is performed to create an initial environmental status file for each storage location.

[0033] When a storage location is used, an immediate scan is triggered to update the environmental data.

[0034] When the host computer requests specific storage location information, a directional scan is performed and the latest data is provided.

[0035] 3. Matching of item type and environmental indicators:

[0036] Establish a database to record the suitable range of environmental indicators for different types of items.

[0037] Analyze the intersection of environmental requirements between items to determine whether they can be stored together.

[0038] For items that can be stored together, assign them to the same storage location group and set unified environmental control parameters.

[0039] 4. Environmental control strategy:

[0040] For storage location groups, implement centralized environmental control, such as unified adjustment of temperature and humidity.

[0041] For items stored separately, independent control is performed according to their specific environmental requirements.

[0042] Use intelligent algorithms to predict environmental change trends and adjust device settings in advance to maintain a stable environment.

[0043] 5. Periodic testing and adjustment:

[0044] Set a fixed detection period to automatically compare real-time environmental indicators with the set interval.

[0045] When an abnormality is detected, the system automatically triggers an alarm and adjusts related equipment (such as turning on dehumidifiers, air conditioners, etc.) according to preset rules.

[0046] Record each adjustment operation and results to optimize future control strategies.

[0047] 6. Data analysis and optimization:

[0048] Collect long-term environmental data and use machine learning algorithms to analyze the optimal environmental conditions for storing items.

[0049] Adjust the storage strategy and environmental control parameters of items based on the analysis results.

[0050] Generate reports regularly and provide them to management for decision support.

[0051] The present invention ensures that different items are stored in the most suitable environment through precise environmental control and classified storage of items, thereby reducing the risk of item damage. Centralized control of item storage groups with similar environmental requirements reduces energy waste and achieves efficient use of resources. The design of using matrix-specified scanning mode and intermediate relay-driven PLC shortens the scanning time and improves the response speed of the system.

[0052] In another preferred embodiment of the present invention, the PLC is driven by an external intermediate relay, and the intermediate relay is placed near the library sensor.

[0053] In another preferred embodiment of the present invention, the single-line scanning time of the vertical library is set to 1 second, of which 0.6 seconds is used to start the relay and scan, and 0.4 seconds is used to close the relay for system discharge.

[0054] This design significantly improves the system's response speed and efficiency by optimizing relay operation and scanning time allocation. Specifically, quickly starting the relay and completing the scan quickly ensures the real-time and accuracy of the data; while a reasonable discharge time helps protect the equipment and extend its service life. Such time configuration not only improves the overall performance of the warehouse management system, but also enhances its reliability and stability, thereby better meeting the needs of modern logistics warehousing.

[0055] In another preferred embodiment of the present invention, when the vertical warehouse is initialized, all storage locations of the entire vertical warehouse are scanned, and the scanning time is n*1 second, which is the number of PLC output points corresponding to the vertical warehouse.

[0056] In another preferred embodiment of the present invention, when a stacker or a robot needs to store or retrieve materials at a certain storage location, the vertical warehouse scans the corresponding storage location individually; when the host computer needs to obtain information about a certain storage location, the vertical warehouse scans the corresponding storage location individually, and when the vertical warehouse does not perform storage location material detection, the vertical warehouse is in standby mode.

[0057] This design enables the system to flexibly scan storage locations according to actual needs, avoiding unnecessary energy waste and equipment wear. At the same time, by precisely controlling the scanning timing, the real-time and accuracy of the data is ensured, and the response speed and work efficiency of the system are improved. In addition, when the vertical warehouse is in standby mode, energy consumption can be further reduced and the life of the equipment can be extended. This intelligent management mode not only optimizes resource allocation, but also improves the overall performance and reliability of the vertical warehouse management system.

[0058] In another preferred embodiment of the present invention, the environmental indicators include but are not limited to temperature, humidity and illumination, and the sensors include but are not limited to temperature sensors, humidity sensors and photoelectric sensors.

[0059] In another preferred situation of the present embodiment, for any pair of different types of items to be stored, the environmental indicator suitable intervals A and environmental indicator suitable intervals B of the corresponding multiple indicators are obtained, and the single suitable intervals of the single indicators are respectively subjected to intersection operations to obtain several sub-intersections, and the set of the sub-intersections is used as the environmental indicator setting interval for the items to be stored.

[0060] By obtaining the environmental indicator suitable intervals A and B of multiple indicators corresponding to any pair of different types of items to be stored, and performing intersection operations on a single indicator to obtain several sub-intersections, these sub-intersection sets are finally used as the environmental indicator setting intervals for the items to be stored. This method can accurately determine the optimal environmental conditions when different types of items coexist, thereby optimizing the efficiency of storage space use and ensuring that each item is stored in the most suitable environment, reducing the risk of item damage. In addition, this method based on intersection operations improves the flexibility and intelligence of the system, enabling it to dynamically adapt to changes in environmental requirements for different items, further improving the overall performance and reliability of the vertical warehouse management system.

[0061] In another preferred embodiment of the present invention, the PLC is also used to receive environmental indicator data collected by sensors. When any real-time environmental indicator exceeds a set range, the PLC controls the corresponding indicator actuator to make adjustments so that the environmental indicator returns to an appropriate range.

[0062] By using sensor data and PLC control, we can automatically adjust environmental indicators and reduce the burden of manual operation. According to the importance and sensitivity of the items, we can dynamically adjust the detection cycle to ensure stricter environmental monitoring of key items.

[0063] In another preferred embodiment of the present invention, the type of items stored in each storage location is collected and assigned a corresponding weight, and the corresponding environmental indicator detection cycle is set according to the value of the weight.

[0064] In another preferred embodiment of the present invention, the opening and closing status, storage status and real-time environmental indicators of the storage location are displayed through a human-computer interaction page. When the environmental indicators exceed the preset range or the storage location fails to open or close, an alarm signal is immediately issued to remind the operator to take corresponding measures.

[0065] The human-machine interaction page provides intuitive information display and alarm functions to facilitate operator monitoring and management.

[0066] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
