It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0020] Embodiment 1 Figure 1 FIG. 1 is a block diagram of a material storage management system provided by an embodiment of the present invention. Figure 1As shown, this embodiment provides a material storage management system, wherein the materials are stored in a material warehouse, wherein a plurality of shelves in a multi-layer structure are deployed in the material warehouse, and a plurality of materials are placed on each layer of each shelf; the system comprises: a management terminal, a plurality of identification tags, a plurality of location tags and an inventory counting instrument; wherein the identification tags and the location tags are both RFID (Radio-Frequency Identification) tags; the management terminal may be a PC computer deployed in each department, and the PC computer may be connected to the inventory counting instrument in communication so as to issue an inventory counting task to the inventory counting instrument; Each identification tag contains basic information of a material, and each identification tag can be detachably connected to the surface of the corresponding material, for example, clamped on the surface of the material or adsorbed on the surface of the material; At least two position tags are installed on each layer of the shelf, and the position tags are used to record the location information of the shelf, and the location information of the shelf includes: the shelf number and the number of layers on the shelf; The inventory counting instrument 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, and 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; 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.

[0021] In this embodiment, a detachable identification tag is installed on each piece of material, and the identification tag can record the basic information of the material, such as batch number, expiration date and other information; when it is necessary to take inventory of the materials in the material warehouse, the inventory counting instrument is started, and the inventory counting instrument automatically reads the basic information in the identification tags on multiple materials on the shelf during movement, which can effectively improve the efficiency and accuracy of the inventory counting; and at least two position tags are installed on each layer of the shelf, and the position tags are used to record the location information of the shelf, such as the shelf number and the number of layers on the shelf, and then the location information of the shelf is obtained; finally, the management terminal is used to determine the materials stored on each layer of the shelf; at this time, not only the distribution of materials in the entire material warehouse can be counted, but also the materials stored on each layer of each shelf can be counted, which improves the practicality of the material inventory and enables medical staff to have a clearer understanding of the distribution of materials in the material warehouse.

[0022] As a further optimization of this embodiment, the inventory counting instrument includes: a mobile platform, on which is mounted an identifier for reading basic information of materials in each identification tag and location information of the shelf in each location tag.

[0023] In this embodiment, the mobile platform adopts a four-wheel mobile platform. The mobile platform has its own driving mechanism, which can drive the mobile platform to move automatically. The identifier is an RFID identifier. The identifier can establish a communication connection with the RFID tag, and can read the basic information of the materials in the identification tag and the location information of the shelf in the location tag. In this embodiment, when the distance between the identification tag or the location tag and the identifier is closer, the strength of the radio frequency signal read by the identifier is greater, and when the distance between the identification tag or the location tag and the identifier is farther, the strength 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 shelf, the distance between the identifier and the identification tag on each material placed on each layer of the shelf needs to be different; then the height of the identifier is less than or equal to the height of the location tag on the bottom layer of the shelf, or the height of the identifier is greater than or equal to the height of the location tag on the highest layer of the shelf.

[0024] As a further optimization of this embodiment, navigation route markings are provided on the ground between the shelves, and the mobile platform is also equipped with a route identification device, which is used to identify the navigation route markings so that the mobile platform moves along the navigation route markings.

[0025] In this embodiment, the shelves are deployed on one side or both sides of the navigation route markings, and the route identification device can be a high-definition camera, etc., to identify the navigation route markings on the ground to control the mobile platform to move along the navigation route markings; when the mobile platform has traveled along the navigation route markings, it can pass through all the shelves and complete the scanning of the materials on all the shelves.

[0026] Embodiment 2 Figure 2 FIG. 1 is a flow chart of a material storage management method provided by an embodiment of the present invention. Figure 2 As shown, this embodiment provides a material warehouse management method, which is implemented based on the material warehouse management system in Embodiment 1. The method is referenced on a management terminal, and the method includes: Step S10: Obtain a material warehouse management request, and generate a medical material inventory task according to the material warehouse management request.

[0027] In this embodiment, the material warehousing management request can be generated directly on the management terminal, or 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, and the material warehousing management request generated on the user is uploaded to the management terminal. The management terminal then generates a medical material inventory task based on the material warehousing management request.

[0028] Step S20: Send the medical supplies inventory task to the inventory counter. When responding to the medical supplies inventory task, the inventory counter moves along a preset path, and during the movement, scans and samples the identification labels on the supplies on the shelves and the location labels on each shelf at a preset sampling frequency to obtain the basic information of the supplies stored on each shelf and the location information of the shelf; and calculates the first signal strength of each location label and the second signal strength of each identification label; wherein the location information of the shelf includes: the shelf number and the number of layers on the shelf.

[0029] In this embodiment, the inventory counting instrument is deployed in a material warehouse, and is used to scan the identification labels on the materials on each shelf and the location labels 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, and calculate the first signal strength of each location label and the second signal strength of each identification label, 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 label and the second signal strength of each identification label to the management terminal; wherein, the inventory counting instrument includes: a mobile platform, on which an identifier is mounted, and the identifier is used to read the basic information of the materials in each identification label and the location information of the shelf in each location label.

[0030] In this embodiment, the preset path movement is a navigation route mark set on the ground between the shelves. The shelves are located on one side or both sides of the navigation route mark. The mobile platform is equipped with a route identification device, such as a high-definition camera. The high-definition camera is used to identify the navigation route mark on the ground to control the mobile platform to move along the navigation route mark. When the mobile platform has traveled along the navigation route mark, it can pass through all the shelves and complete the scanning of the materials on all the shelves.

[0031] In this embodiment, after completing the scanning and collection of materials on the shelves of the entire material warehouse, the remaining quantity of each material in the entire material warehouse can be counted, but at this time it is impossible to determine which shelf each material is placed on, and whether the position of the material on the shelf is accurate; therefore, it is necessary to determine the position of each material on the shelf.

[0032] Step S30: Determine the materials belonging to the same shelf and the layer number of the materials on the same shelf according to the location information of the shelf, the first signal strength and the second signal strength.

[0033] In this embodiment, when the basic information of the materials is entered into the identification tag, the shelf number and the number of layers where the materials are to be stored are also entered into the identification tag. When the identifier reads the information in the identification tag, the shelf number and the number of layers of the materials can be directly obtained. However, the method will reduce the flexibility of the storage location of the materials in actual application, and the materials need to be accurately stored on the designated shelves; if the medical staff puts the materials in the wrong storage location when entering the warehouse, it will cause errors in the inventory of the actual location of the materials, and it will be difficult to find. In order to solve the above problems, at least two location tags are installed on each layer of each shelf. The location tags are also RFID tags. Only the shelf number and the number of layers are entered in the location tags. By reading the information in the location tags, the shelf number and the number of layers can be directly obtained; in this embodiment, it is preferred to arrange two location tags on each layer of the shelf.

[0034] In order to accurately determine the location of each material on the shelf, the materials belonging to the same shelf and the number of layers of the materials on the same shelf are determined according to the location information of the shelf, the first signal strength and the second signal strength, including: Step S301: Filter out the maximum value of the first signal strength of each location tag at the same side endpoint of each layer on the same shelf, and determine the entry and departure times of the inventory counting instrument passing through the shelf according to the maximum value of the first signal strength of each location tag at the same side endpoint of each layer on the same shelf; in this embodiment, the identifier of the inventory counting instrument uses 0.01s~0.1s as the scanning period (that is, the preset sampling frequency), and the mobile platform travels at a constant speed of 0.2m / s~0.5m / s to scan the location tags and identification tags on the shelves, so as to read the information in the location tags and identification tags, and at the same time, the strength of the radio frequency signal when the identification tags of each material are read, that is, the first signal strength, and the strength of the radio frequency signal when the location tag is read, that is, the second signal strength.

[0035] During the driving process of the mobile platform, when the identifier is located directly in front of the location tag or the identification tag, the collected RF signal strength of the location tag is the largest or the RF signal strength of the identification tag is the largest; when the collected RF signal strength of the location tag is the largest, it means that the mobile platform has moved to the front of one side of a shelf, this position is the starting position of the shelf, and this moment is the entry moment.

[0036] Step S302: At the time of driving in, extract the first signal strength of each position tag 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 tag at the two side endpoints of each layer of the shelf.

[0037] After the mobile platform reaches the starting position of a shelf, the second signal strengths of all the position tags on the shelf are extracted. At this time, the second signal strengths of all the position tags on the shelf can constitute a signal strength range, that is, the strength range of the shelf. When the second signal strength of any identification tag falls into the strength range of the shelf, it means that the materials corresponding to the identification tag are on the shelf; if it does not fall into the strength range of the shelf, it means that the materials corresponding to the identification tag are not on the shelf, but are materials on other shelves. After executing step S303, all the materials on a shelf can be obtained.

[0038] Step S303: Determine whether the second signal strength of each identification tag falls within the strength range of the shelf. If so, the material corresponding to the identification tag is marked as belonging to the shelf; if not, the material corresponding to the identification tag is marked as not belonging to the shelf. After taking inventory of all the materials on a shelf, it can only be proved that a certain material is on this shelf, but the specific number of layers is unclear. Therefore, it is necessary to determine the number of layers of each material on the shelf, such as the first layer, the second layer, and the third layer.

[0039] Step S304: Construct the intensity range of each layer of the shelf according to the maximum value of the first signal strength of each location tag at the end point on the same side of each layer on the shelf; in the present embodiment, the intensity range of the first layer of the shelf is constituted by the maximum value of the second signal strength of the location tags of the first layer and the maximum value of the second signal strength of the location tags of the second layer, and the intensity range of the second layer of the shelf is constituted by the maximum value of the second signal strength of the location tags of the second layer and the maximum value of the second signal strength of the location tags of the third layer; the intensity range of the top layer of the shelf is constituted by the maximum value of the second signal strength of the location tags greater than that of the top layer.

[0040] Step S305: between the time when the inventory counter enters and leaves the shelf, extract the maximum signal strength of the first signal strengths corresponding to the materials on the shelf at multiple sampling times; wherein the sampling time is determined by a preset sampling frequency.

[0041] 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 entry time and the departure time, the identification tag on a material will collect multiple radio frequency signals. When the identifier on the mobile platform moves to the front of the material, the intensity of the radio frequency signal is the largest, and the radio frequency signal is extracted as the maximum signal intensity among the first signal intensities corresponding to the material at multiple sampling times. 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 the 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 of the first layer at multiple sampling times is greater than or equal to the maximum value of the second signal intensity of the position tag of the first layer, and is 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 means that the material is on the first layer of the shelf.

[0042] Step S306: Determine the layer number of each material belonging to the shelf according to the maximum signal strength among the first signal strengths corresponding to each material belonging to the shelf at multiple sampling moments and the strength range of each layer; through this step, the materials on each layer of the shelf can be counted, that is, the layer number of each material belonging to the shelf.

[0043] Step S40: According to the number of layers of materials on the same shelf, take inventory of the materials stored on each layer of each shelf to obtain the inventory result, which includes the total quantity of each material in the entire material warehouse, the distribution of each material on each shelf, and the number of layers of each material on the shelf; the inventory result is displayed on the management terminal, or the inventory result is sent to the user terminal of the medical staff responsible for the management of the material warehouse, and the medical staff and other users can directly view the inventory result.

[0044] As a further optimization of this embodiment, the method further includes: Step a10: Obtaining the initial position of each material on the shelf, the initial position includes: the initial shelf number and the initial number of layers on the shelf, the initial position is recorded when entering the warehouse; Step a10: Based on the initial position of each material on the shelf, determine whether there is any storage abnormality in the materials stored on each layer of each shelf. If so, generate an abnormal label.

[0045] In this embodiment, if materials belonging to shelf A are mistakenly placed on shelf B due to negligence of the staff, the actual shelf number and layer number of each material can be determined after each inventory, so that it can be directly judged that the material is placed in the wrong place, and the material can be marked and displayed on the management terminal to inform the medical staff, so that the medical staff can quickly find the misplaced materials and avoid the materials being left out on shelf B for a long time.

[0046] The present invention installs a detachable identification label on each material, and the identification label can record the basic information of the material, such as batch number, expiration date and other information; when it is necessary to take inventory of the materials in the material warehouse, the inventory counting instrument is started, and the inventory counting instrument automatically reads the basic information in the identification labels on multiple materials on the shelf during movement, which can effectively improve the efficiency and accuracy of the inventory counting; and at least two position labels are installed on each layer of the shelf, and the position labels are used to record the position information of the shelf, such as the shelf number and the number of layers on the shelf, and then the position information of the shelf is obtained; finally, the materials stored on each layer of the shelf are determined by using the management terminal; at this time, not only the distribution of materials in the entire material warehouse can be counted, but also the materials stored on each layer of each shelf can be counted, thereby improving the practicability of the material inventory and enabling medical staff to more clearly understand the distribution of materials in the material warehouse.
