[0002] Medical supplies are consumable medical devices with a limited number of uses approved by the drug regulatory department, including disposable and reusable medical consumables, such as infusion sets, syringes, dressings, catheters, guide wires, stents, and other consumables dedicated to clinical departments.

[0003] Currently, medical supplies are usually stored in one or more warehouses dedicated to storing materials. These warehouses are usually divided into different areas for storing different types of materials, such as drugs, medical devices, consumables, office supplies, etc.

[0004] Usually, after medical supplies are warehoused or out of stock, it is necessary to regularly inventory the materials in the warehouse. Traditional inventory methods often use manual inventory. Staff use tools such as counters, barcode scanners, and inventory forms to check each material one by one, record information such as quantity, batch number, and expiration date, and compare the inventory results with the data in the inventory management system to determine the usage and inventory status of the materials in the warehouse.

[0005] However, in the actual application process of this method, it is easy to miss counting, resulting in a low accuracy rate of the inventory results, and the efficiency of the method of checking one by one is also low. Summary of the Invention

[0006] The purpose of the present invention is to provide a material warehousing management system, method, device, and storage medium to solve the problems that in the actual application process of the existing inventory method, it is easy to miss counting, resulting in a low accuracy rate of the inventory results, and the efficiency of the method of checking one by one is also low.

Obviously, the following description of the structures of the accompanying drawings is only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other accompanying drawings can be obtained based on these drawings. It should be noted here that the description of these embodiment modes is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0042] Embodiment 1

[0043] Figure 1 is a block diagram of a material warehousing management system provided by an embodiment of the present invention. As Figure 1 shown, this embodiment provides a material warehousing management system. The materials are stored in a material warehouse, and several multi-layer shelves are deployed in the material warehouse. Each layer of each shelf is placed with several materials. The system includes: a management terminal, several identification tags, several location tags, and an inventory scanner. Among them, both the identification tags and the location tags are RFID (Radio-Frequency Identification) tags. The management terminal can be a PC computer deployed in each department, and the PC computer can be communicatively connected to the inventory scanner to issue an inventory task to the inventory scanner;

[0044] The basic information of one material is entered into each identification tag, and each identification tag is detachably connected to the surface of the corresponding material, such as being clamped on the surface of the material or adsorbed on the surface of the material;

[0045] At least two location tags are installed on each layer of the shelf. The location tags are used to record the location information of the shelf. The location information of the shelf includes: the shelf number and the number of layers on the shelf;

[0046] The inventory scanner is deployed in the material warehouse and is used to scan the identification tags on the materials on each shelf and the location tags on each shelf during movement, so as to obtain the basic information of the materials stored on each shelf and the location information of the shelf, calculate the first signal strength of each location tag and the second signal strength of each identification tag, and upload the obtained basic information of the materials stored on each shelf, the location information of the shelf, and the calculated first signal strength of each location tag and the second signal strength of each identification tag to the management terminal;

[0047] The management terminal is used to: count the materials stored on each layer of each shelf according to the basic information of the materials stored on each shelf, the location information of the shelf, the first signal strength of each location tag, and the second signal strength of each identification tag.

[0048] In this embodiment, by installing a detachable identification tag on each piece of material, the identification tag can record the basic information of the material, such as batch number, expiration date, etc.; when it is necessary to take an inventory of the materials in the material warehouse, the inventory scanner is started. During the movement of the inventory scanner, it automatically reads the basic information in the identification tags on multiple pieces of materials on the shelf, which can effectively improve the efficiency and accuracy of the inventory; and by installing at least two location tags on each layer of the shelf, the location tags are used to record the location information of the shelf, such as shelf number and the number of layers on the shelf, and then obtain the location information of the shelf; finally, the management terminal is used to determine the materials stored on each layer of the shelf; at this time, not only can the distribution of the materials in the entire material warehouse be counted, but also the materials stored on each layer of each shelf can be counted, improving the practicability of the material inventory and enabling medical staff to more clearly understand the distribution of the materials in the material warehouse.

[0049] As a further optimization of this embodiment, the inventory scanner includes: a mobile platform, and an identifier is mounted on the mobile platform. The identifier is used to read the basic information of the materials in each identification tag and the location information of the shelf in each location tag.

[0050] In this embodiment, the mobile platform adopts a four-wheel mobile platform. The mobile platform is equipped with a driving mechanism that can drive the mobile platform to move automatically. The identifier is an RFID identifier, which can establish a communication connection with the RFID tag and can read the basic information of the materials in the identification tag and the position information of the shelves in the position tag. In this embodiment, when the identification tag or the position tag is closer to the identifier, the intensity of the radio frequency signal read by the identifier is greater; when the identification tag or the position tag is farther from the identifier, the intensity of the radio frequency signal read by the identifier is smaller. Therefore, in order to accurately determine the materials placed on each layer of the storage shelf, the distances between the identifier and the identification tags on each material placed on each layer of the storage shelf need to be different. Then the height of the identifier is less than or equal to the height of the position tag on the bottom layer of the storage shelf, or the height of the identifier is greater than or equal to the height of the position tag on the top layer of the storage shelf.

[0051] As a further optimization of this embodiment, navigation line identifiers are provided on the ground between the storage shelves, and a line identification device is also mounted on the mobile platform. The line identification device is used to identify the navigation line identifiers so that the mobile platform moves along the navigation line identifiers.

[0052] In this embodiment, the storage shelves are deployed on one side or both sides of the navigation line identifiers. The line identification device can be a high-definition camera or the like to identify the navigation line identifiers on the ground to control the mobile platform to move along the navigation line identifiers. After the mobile platform finishes traveling along the navigation line identifiers, it can pass by all the storage shelves and complete the scanning of the materials on all the storage shelves.

[0053] Embodiment 2

[0054] Figure 2 It is a flowchart of a method for managing materials in a warehouse provided by an embodiment of the present invention. As Figure 2 shown, this embodiment provides a method for managing materials in a warehouse. The method is implemented based on the materials warehouse management system in Embodiment 1. This method is applied to the management terminal. The method includes:

[0055] Step S10: Obtain a materials warehouse management request and generate a medical materials inventory task according to the materials warehouse management request.

[0056] In this embodiment, the materials warehouse management request can be directly generated on the management terminal, or generated on the user terminal of the medical staff (such as a smart phone). The user terminal can establish a communication connection with the management terminal through the Internet. The materials warehouse management request generated on the user is uploaded to the management terminal, and the management terminal then generates a medical materials inventory task according to the materials warehouse management request.

[0057] Step S20: Send the medical supplies inventory task to the inventory device. When the inventory device responds to the medical supplies inventory task, it moves along a preset path and, during the movement, scans and samples the identification tags on the supplies on the shelves and the position tags on each shelf at a preset sampling frequency to obtain the basic information of the supplies stored on each shelf and the position information of the shelves; and calculates the first signal strength of each position tag and the second signal strength of each identification tag. Among them, the position information of the shelf includes: shelf number and the number of layers on the shelf.

[0058] In this embodiment, the inventory device is deployed in the supplies warehouse. The inventory device is used to scan the identification tags on the supplies on each shelf and the position tags on each shelf during the movement to obtain the basic information of the supplies stored on each shelf and the position information of the shelves, calculate the first signal strength of each position tag and the second signal strength of each identification tag, and upload the basic information of the supplies stored on each shelf, the position information of the shelves, and the calculated first signal strength of each position tag and the second signal strength of each identification tag to the management terminal. Among them, the inventory device includes: a mobile platform, and an identifier is mounted on the mobile platform. The identifier is used to read the basic information of the supplies in each identification tag and the position information of the shelves in each position tag.

[0059] In this embodiment, the preset path movement is a navigation line identifier set on the ground between the shelves. The shelves are located on one side or both sides of the navigation line identifier. A line recognition device, such as a high-definition camera, is mounted on the mobile platform. The high-definition camera is used to recognize the navigation line identifier on the ground to control the mobile platform to move along the navigation line identifier. When the mobile platform finishes traveling along the navigation line identifier, it can pass by all the shelves and complete the scanning of the supplies on all the shelves.

[0060] In this embodiment, after completing the scanning and collection of the supplies on the shelves in the entire supplies warehouse, the remaining quantity of each supply in the entire supplies warehouse can be inventoried, but at this time, it is impossible to determine on which shelf each supply is placed and whether the position of the supply on the shelf is accurate. Therefore, it is necessary to determine the position of each supply on the shelf.

[0061] Step S30: Determine the supplies belonging to the same shelf and the layer where the supplies on the same shelf are located according to the position information of the shelf, the first signal strength, and the second signal strength.

[0062] In this embodiment, when entering the basic information of the supplies into the identification label, the shelf number and the layer number where the supplies are to be stored can be entered into the identification label at the same time. When the identifier reads the information in the identification label, the shelf number and the layer number of the supplies can be directly obtained. However, this method will reduce the flexibility of the storage location of the supplies in actual application, and the supplies need to be accurately stored on the designated shelf; if the medical staff misplace the storage location of the supplies during warehousing, it will lead to errors in the actual location inventory of the supplies and it is difficult to discover. To solve the above problems, at least two position labels are installed on each layer of each shelf. The position labels are also RFID labels, and only the shelf number and the layer number are entered in the position labels. By reading the information in the position labels, the shelf number and the layer number can be directly obtained; in this embodiment, it is preferably to arrange two position labels on each layer of the shelf.

[0063] In order to accurately determine the positions of the supplies on the shelf, according to the position information of the shelf, the first signal strength, and the second signal strength, the supplies belonging to the same shelf and the layer where the supplies on the same shelf are located are determined, including:

[0064] Step S301: Screen out the maximum value of the first signal strength of each position label at the same-side endpoints of each layer on the same shelf. According to the maximum value of the first signal strength of each position label at the same-side endpoints of each layer on the same shelf, determine the entry time and the departure time when the inventory instrument passes through the shelf; in this embodiment, the identifier of the inventory instrument uses a scanning period of 0.01s to 0.1s (i.e., the preset sampling frequency), and the mobile platform travels at a constant speed of 0.2m / s to 0.5m / s, scans the position labels and identification labels on the shelf, can read the information in the position labels and identification labels, and can also calculate the intensity of the radio frequency signal when reading the identification label of each supply, that is, the first signal strength, and the intensity of the radio frequency signal when reading the position label, that is, the second signal strength.

[0065] During the travel of the mobile platform, when the identifier is directly in front of the position label or the identification label, the radio frequency signal strength of the position label or the radio frequency signal strength of the identification label collected at this time is the largest; when the radio frequency signal strength of the position label collected is the largest, it means that the mobile platform has moved to the front of one side of a shelf, and this position is the starting position of the shelf, and this moment is the entry time.

[0066] Step S302: At the entry time, extract the first signal strength of each position label at the two-side endpoints of each layer of the shelf, and construct the intensity range to which the shelf belongs according to the first signal strength of each position label at the two-side endpoints of each layer of the shelf.

[0067] After the mobile platform reaches the starting position of a shelf, extract the second signal strength of all position tags on this shelf. At this time, the second signal strengths of all position tags on this shelf can form a signal strength range, that is, the strength range to which the shelf belongs. When the second signal strength of any identification tag falls within the strength range to which the shelf belongs, it indicates that the material corresponding to this identification tag is on this shelf; if it does not fall within the strength range to which the shelf belongs, it indicates that the material corresponding to this identification tag is not on this shelf but is a material on other shelves. After step S303 is executed, all materials on a shelf can be obtained.

[0068] Step S303: Determine whether the second signal strength of each identification tag falls within the strength range to which the shelf belongs. If so, mark the material corresponding to this identification tag as belonging to this shelf; if not, mark the material corresponding to this identification tag as not belonging to this shelf. After inventorying all materials on a shelf, it can only prove that a certain material is on this shelf, but the specific layer is not clear. Therefore, it is also necessary to determine the layer of each material on the shelf, such as the first layer, the second layer, and the third layer, etc.

[0069] Step S304: Construct the strength range to which each layer of the shelf belongs based on the maximum value of the first signal strength of the position tags at the same-side endpoints of each layer on this shelf; in this embodiment, the maximum value of the second signal strength of the position tags of the first layer and the maximum value of the second signal strength of the position tags of the second layer are used to form the strength range to which the first layer of the shelf belongs, and the maximum value of the second signal strength of the position tags of the second layer and the maximum value of the second signal strength of the position tags of the third layer are used to form the strength range to which the second layer of the shelf belongs; the maximum value greater than the maximum value of the second signal strength of the position tags of the top layer is used to form the strength range to which the top layer of the shelf belongs.

[0070] Step S305: Extract the maximum signal strength among the first signal strengths corresponding to multiple sampling moments of the materials belonging to this shelf between the moment when the inventory instrument enters this shelf and the moment when it leaves. Among them, the sampling moments are determined by a preset sampling frequency.

[0071] In this embodiment, the moving direction of the mobile platform in front of the shelf is parallel to the length direction of the shelf. Between the driving-in moment and the driving-out moment, an identification tag on a material will collect multiple radio frequency signals. When the identifier on the mobile platform moves to directly in front of this material, the intensity of the radio frequency signal is the maximum. This radio frequency signal is extracted as the maximum signal intensity among the first signal intensities corresponding to the material at multiple sampling moments. Taking the first layer of the shelf in this embodiment as an example, the position tag of the first layer is at the bottom of this layer. The height of the identification tag on the material is usually greater than the height of the position tag of the first layer and lower than the height of the position tag of the second layer. That is, the identification tag of the material on the first layer is in the area between the position tag of the first layer and the position tag of the second layer. Then, the maximum signal intensity among the first signal intensities corresponding to the material on the first layer at multiple sampling moments is greater than or equal to the maximum value of the second signal intensity of the position tag of the first layer and less than the maximum value of the second signal intensity of the position tag of the second layer. When the maximum signal intensity of the first signal intensity corresponding to any material is between the maximum value of the second signal intensity of the position tag of the first layer and the maximum value of the second signal intensity of the position tag of the second layer, it indicates that this material is on the first layer of the shelf.

[0072] Step S306: Determine the layers where each material belonging to the shelf is located according to the maximum signal intensity among the first signal intensities corresponding to each material belonging to the shelf at multiple sampling moments and the belonging intensity range of each layer; through this step, the materials on each layer of the shelf can be inventoried, that is, the layers where each material belonging to the shelf is located.

[0073] Step S40: Inventory the materials stored on each layer of each shelf according to the layers where the materials on the same shelf are located to obtain an inventory result. The inventory result includes information such as the total quantity of each material in the entire material warehouse, the distribution of each material on each shelf, and the layer number of each material on the shelf; display the inventory result on the management terminal, or send the inventory result to the user terminal of the medical staff responsible for the management of this material warehouse. Users such as medical staff can directly view the inventory result.

[0074] As a further optimization of this embodiment, the method further includes:

[0075] Step a10: Obtain the initial positions of each material on the shelf. The initial positions include: the initial shelf number and the initial layer number on the shelf, and the initial positions are recorded during warehousing;

[0076] Step a10: Based on the initial positions of each material on the shelf, determine whether there are abnormal storage situations for the materials stored on each layer of each shelf. If so, generate an abnormal label.

[0077] In this embodiment, if due to the negligence of the staff, the supplies belonging to Shelf A are accidentally placed on Shelf B, after each inventory, the actual shelf number and layer number of each supply can be determined, and it can be directly judged that this supply is placed in the wrong place. Then, this supply is marked and displayed on the management terminal to inform the medical staff, which can facilitate the medical staff to quickly find the supplies placed in the wrong position and avoid this supply being left on Shelf B for a long time.

[0078] In the present invention, a detachable identification label is installed on each supply. The identification label can record the basic information of the supply, such as batch number, expiration date, etc. When it is necessary to take an inventory of the supplies in the supply warehouse, the inventory instrument is started. During the moving process of the inventory instrument, it automatically reads the basic information in the identification labels on multiple supplies on the shelf, which can effectively improve the efficiency and accuracy of the inventory. And by installing at least two position labels on each layer of the shelf, the position labels are used to record the position information of the shelf, such as the shelf number and the layer number on the shelf, and then the position information of the shelf is obtained. Finally, the management terminal is used to determine the supplies stored on each layer of the shelf. At this time, not only can the distribution of the supplies in the entire supply warehouse be counted, but also it can be counted which supplies are stored on each layer of each shelf, improving the practicality of the supply inventory and enabling the medical staff to more clearly understand the distribution of the supplies in the supply warehouse.
