This data is crucial for assessing the actual demand for supplies and optimizing inventory allocation. The lack of in-depth analysis of this data affects the efficiency of medical supply use and management. Summary of the Invention

[0026] Obtain the usage value of medical supplies and compare it with the usage threshold of medical supplies;

[0027] If the usage value of medical supplies exceeds the medical supply usage threshold, a high usage signal is generated.

[0028] As a further aspect of the present invention: the process for obtaining the resource utilization ratio is as follows:

[0029] Perform timed inspections on the EPC area, and mark the time intervals as inspection periods;

[0030] Get the resource usage of the EPC area at the end of the detection period, and get the maximum resource capacity of the EPC area. The maximum resource capacity is the maximum amount of resources that the EPC area can support.

[0031] The resource usage ratio is obtained by comparing the resource usage of the EPC area at the end of the detection period with the maximum resource usage.

[0032] As a further aspect of the present invention: the process for obtaining the CPU utilization ratio is as follows:

[0033] Obtain the total CPU usage time within the detection period, and then calculate the ratio between the total CPU usage time within the detection period and the total time of the detection period to obtain the CPU usage ratio.

[0034] As a further aspect of the present invention: the process of obtaining the judgment value is as follows:

[0035] Resource utilization ratio and CPU utilization ratio;

[0036] Substituting into the formula PD=s1*ZY+s2*PC, the usage judgment value PD is calculated, where ZY represents the resource utilization ratio, PC represents the CPU utilization ratio, and s1 and s2 are preset ratio coefficients.

[0037] As a further aspect of the present invention: the process of generating the high utilization signal is as follows:

[0038] Obtain the usage judgment value and compare it with the usage judgment threshold;

[0039] If the judgment value is greater than the judgment threshold, a high usage signal is generated.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Example 1:

[0058] Please see Figure 1 and Figure 2 As shown in the embodiment of the present invention, a method for allocating the EPC field space of RFID electronic tags for medical supplies comprises the following steps:

[0059] Step 1: Obtain the usage frequency and duration values ​​of medical supplies from historical data, process them, and calculate the medical supply usage data;

[0060] The data on material usage includes frequency representation values ​​and duration representation values;

[0061] In some embodiments, a preset monitoring period is provided, and the monitoring period can be set to include, but is not limited to, one day, one week, or one month.

[0062] Obtain the usage frequency and duration values ​​of medical supplies from multiple monitoring periods in historical data;

[0063] It should be noted that medical supplies include, but are not limited to: medicines, medical devices, and consumables;

[0064] For example, the process of obtaining frequency representation values ​​is as follows:

[0065] The obtained usage frequency values ​​are compared with the usage frequency threshold, which is a critical value used to determine the level of usage frequency. It is set by those skilled in the art based on historical experimental data.

[0066] If the usage frequency value is less than or equal to the usage frequency threshold, it indicates that the usage frequency of medical supplies is not high during the monitoring period, and a low usage frequency signal is generated.

[0067] If the usage frequency value is greater than the usage frequency threshold, it indicates that the medical supplies are used more frequently during the monitoring period, generating a high usage frequency signal.

[0068] The monitoring period for generating and using high-frequency signals is identified and marked as a high-frequency monitoring period.

[0069] The number of high-frequency monitoring cycles is obtained, and the ratio of the number of high-frequency monitoring cycles to the total number of monitoring cycles is processed to obtain the high-frequency proportion value.

[0070] Obtain the usage frequency value of the high-frequency monitoring cycle, calculate the difference between the usage frequency value of the high-frequency monitoring cycle and the usage frequency threshold to obtain the usage frequency deviation value, sum the usage frequency deviation values ​​of all high-frequency monitoring cycles to obtain the total usage frequency deviation value, and calculate the ratio of the total usage frequency deviation value to the usage frequency threshold to obtain the high frequency level value.

[0071] The frequency characterization value is obtained by multiplying the high frequency proportion value and the high frequency degree value.

[0072] It needs to be explained that the frequency characterization value reflects the following meaning: the frequency characterization value is calculated from the high frequency proportion value and the high frequency degree value. That is, the larger the high frequency proportion value, the more monitoring cycles corresponding to the high frequency signal are used, the larger the frequency characterization value, and the higher the frequency of use of medical supplies. That is, the larger the high frequency degree value, the larger the difference between the usage frequency value corresponding to the high frequency monitoring cycle and the usage frequency threshold, that is, the greater the frequency deviation, and the higher the frequency of use of medical supplies.

[0073] For example, the process of obtaining the duration representation value is as follows:

[0074] The obtained usage duration values ​​are compared with the usage duration threshold, where the usage threshold is a critical value used to determine the length of usage duration. It is set by those skilled in the art based on historical experimental data.

[0075] If the usage duration value is less than or equal to the usage duration threshold, it indicates that the usage duration of medical supplies is short within the monitoring period, and a short usage duration signal is generated.

[0076] If the usage duration value is greater than the usage duration threshold, it indicates that the medical supplies have been used for a longer period of time during the monitoring period, and a signal indicating a longer usage duration is generated.

[0077] The monitoring period for generating signals with longer usage time is obtained and marked as a high-duration monitoring period;

[0078] Obtain the number of high-duration monitoring periods, and then calculate the ratio of the number of high-duration monitoring periods to the total number of monitoring periods to obtain the high-duration percentage.

[0079] Obtain the usage duration value of the high-duration monitoring period, calculate the difference between the usage duration value of the high-duration monitoring period and the usage duration threshold to obtain the usage duration deviation value, sum the usage duration deviation values ​​of all high-duration monitoring periods to obtain the total usage duration deviation value, and calculate the ratio of the total usage duration deviation value to the usage duration threshold to obtain the high duration level value;

[0080] The duration representation value is obtained by multiplying the high duration percentage value with the high duration severity value.

[0081] It should be explained that the meaning reflected by this duration representation value is as follows: the duration representation value is calculated from the high duration proportion value and the high duration degree value. That is, the larger the high duration proportion value, the more monitoring cycles corresponding to the longer signal usage time, and the larger the duration representation value. In other words, the larger the high duration degree value, the higher the frequency of use of medical supplies. That is, the larger the duration degree value, the larger the difference between the usage value corresponding to the high duration monitoring cycle and the usage duration threshold, that is, the greater the duration deviation, and the higher the frequency of use of medical supplies.

[0082] Step 2: Obtain medical supply usage data, calculate medical supply usage value, and assess the degree of medical supply usage;

[0083] In some embodiments, frequency and duration characterization values ​​of medical supplies are obtained;

[0084] Substitute into the formula The medical supplies usage value SY is calculated, where PL represents the frequency characterization value, SC represents the duration characterization value, and a1 and a2 are preset proportional coefficients.

[0085] The value of medical supplies usage is compared with the threshold for medical supplies usage, wherein the threshold for medical supplies usage is set by a person skilled in the art based on historical experimental data.

[0086] If the value of medical supplies usage is less than or equal to the threshold for medical supplies usage, it indicates that the degree of medical supplies usage is not high, and a low-to-high usage signal is generated.

[0087] If the value of medical supplies usage is greater than the threshold for medical supplies usage, it indicates that the degree of medical supplies usage is relatively high, generating a high degree of usage signal;

[0088] The technical solution of this invention mainly involves: acquiring the usage frequency and usage duration values ​​of medical supplies from historical data; calculating usage frequency representation values ​​and usage duration representation values ​​based on the acquired usage frequency and usage duration values; calculating the medical supply usage value; comparing the medical supply usage value with the medical supply usage threshold; and generating a high usage signal or a low usage signal. This allows for the judgment of the usage degree of medical supplies based on historical data, and further allows for more reasonable allocation based on the judgment results, thereby improving the efficiency and management level of medical supply use.

[0089] Example 2:

[0090] Based on Example 1, the method for allocating the EPC field space of RFID electronic tags for medical supplies according to this embodiment of the invention further includes the following steps:

[0091] Step 3: Based on the generated high-usage signals, set the EPC zone and user zone for the RFID electronic tags of medical supplies;

[0092] In some embodiments, medical supplies that generate high usage signals are acquired and marked as high-usage medical supplies.

[0093] For example, the process of setting up the EPC area is as follows:

[0094] EPC codes are set for medical supplies with high usage. The coding structure that EPC codes can support includes, but is not limited to, batch information, serial number, and manufacturer code.

[0095] For example, the user area setup process is as follows:

[0096] Obtain the total amount of additional storage information for medical supplies, including but not limited to: protection information, usage records, expiration dates, storage conditions, and other specific information;

[0097] The total amount of additional stored information is compared with the threshold for the total amount of additional stored information, wherein the threshold for the total amount of additional stored information is set by those skilled in the art based on historical experimental data;

[0098] If the total amount of additional storage information is less than or equal to the additional storage information threshold, the EPC area may already be sufficient to store all the necessary information, and the user area setting can be cancelled;

[0099] If the total amount of additional storage information exceeds the threshold for additional storage information, then a user area is set.

[0100] It should be noted that the size of the user area needs to be set according to the total amount of additional storage information;

[0101] Step 4: Obtain usage data for the EPC area, process it, calculate the usage judgment value, and compare it with the usage judgment threshold to determine the usage level of the EPC area;

[0102] The usage data includes resource utilization ratio and CPU utilization ratio;

[0103] In some embodiments, the EPC area is periodically inspected, wherein the inspection period (i.e., the time interval) is set by those skilled in the art based on historical experience;

[0104] Get the resource usage of the EPC area at the end of the detection period, and get the maximum resource capacity of the EPC area. The maximum resource capacity is the maximum amount of resources that the EPC area can support.

[0105] The resource utilization ratio is obtained by comparing the resource usage of the EPC area at the end of the detection period with the maximum resource usage.

[0106] Obtain the total CPU usage time within the detection period, and then calculate the ratio of the total CPU usage time within the detection period to the total time of the detection period to obtain the CPU usage ratio.

[0107] Substituting into the formula PD=s1*ZY+s2*PC, the usage judgment value PD is calculated, where ZY represents the resource utilization ratio, PC represents the CPU utilization ratio, and s1 and s2 are preset ratio coefficients;

[0108] It needs to be explained that the meaning reflected by the judgment value is: the judgment value is calculated from the resource utilization ratio and the CPU utilization ratio. That is, the larger the resource utilization ratio, the larger the judgment value, and the higher the resource utilization rate. In other words, the larger the CPU resource ratio, the larger the judgment value, the higher the system is under high load and the higher the utilization rate.

[0109] The judgment value is compared with the judgment threshold, wherein the judgment threshold is set by a person skilled in the art based on historical experimental data.

[0110] If the judgment value is less than or equal to the judgment threshold, a low usage signal is generated;

[0111] If the judgment value is greater than the judgment threshold, a high usage signal is generated;

[0112] Optimization and adjustments are made based on the generated high-frequency signals;

[0113] The optimization and adjustment measures include, but are not limited to:

[0114] Dynamically adjust the size of the EPC area and the user area: free up more space for the EPC area by reducing the size of the user area or completely eliminating the user area;

[0115] Optimize data processing flow: Reduce the CPU load when handling EPC area related operations, for example by optimizing algorithms, increasing cache, or parallel processing;

[0116] The main technical solution of this invention is as follows: by setting detailed EPC codes for high-use medical supplies, including batch information, serial number and manufacturer code, these supplies can be quickly identified and tracked, improving the efficiency of inventory management and logistics operations. A user area is set up to store additional maintenance information, usage records, expiration dates, storage conditions, etc., so that managers can quickly obtain comprehensive information about the supplies, which is convenient for daily management and maintenance.

[0117] Meanwhile, by periodically monitoring the usage data of the EPC area and calculating the usage judgment value based on the acquired usage data, the utilization rate is evaluated, and a high utilization rate signal or a low utilization rate signal is generated. When a high utilization rate signal is generated, timely adjustments are made, thereby effectively monitoring the usage of the EPC area, optimizing resource allocation when the utilization rate is high, and ensuring the normal operation of the system.

[0123] EPC Area Usage Determination Module: Acquires and processes usage data of the EPC area, calculates a usage determination value, and compares it with a usage determination threshold to determine the usage level of the EPC area.
