[0056] 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.

[0057] Embodiment 1:

[0058] See also Figure 1 and Figure 2 As shown, the method for allocating EPC field space of an RFID electronic tag of medical supplies according to an embodiment of the present invention comprises the following steps:

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

[0060] Among them, the material usage value data includes frequency representation value and duration representation value;

[0061] In some embodiments, a monitoring period is preset, and the settings of the monitoring period include but are not limited to: one day, one week, one month;

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

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

[0064] Exemplarily, the process of obtaining the frequency characterization value is as follows:

[0065] The obtained usage frequency values ​​are compared with the usage frequency thresholds, where the usage frequency threshold is a critical value used to judge the high or low usage frequency, and is set by those skilled in the art based on the historical experimental data.

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

[0067] If the usage frequency value is greater than the usage frequency threshold, it means that the usage frequency of medical supplies is high during the monitoring period, and a high usage frequency signal is generated;

[0068] Obtain the monitoring period that generates the high-frequency signal and mark it as the high-frequency monitoring period;

[0069] Obtain the number of high-frequency monitoring cycles, perform ratio processing on the number of high-frequency monitoring cycles and the total number of monitoring cycles to obtain the high-frequency ratio value;

[0070] Obtain the usage frequency value of the high-frequency monitoring period, perform difference calculation between the usage frequency value of the high-frequency monitoring period and the usage frequency threshold value respectively to obtain the usage frequency deviation value, sum the usage frequency deviation values ​​of all high-frequency monitoring periods to obtain the total usage frequency deviation value, perform ratio calculation between the total usage frequency deviation value and the usage frequency threshold value to obtain the high frequency degree value;

[0071] The high frequency proportion value is multiplied by the high frequency degree value to obtain the frequency representation value;

[0072] It needs to be explained that the meaning reflected by the frequency characterization value is: the frequency characterization value is calculated by the high frequency proportion value and the high frequency degree value, that is, the larger the high frequency proportion value is, the more monitoring cycles corresponding to the signals with high usage frequency are, the larger the frequency characterization value is, the higher the usage frequency of medical supplies is, that is, the larger the high frequency degree value is, the larger the difference between the usage frequency value corresponding to the high frequency monitoring cycle and the usage frequency threshold is, that is, the larger the frequency deviation is, the higher the usage frequency of medical supplies is;

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

[0074] The obtained usage time values ​​are compared with the usage time thresholds respectively, wherein the usage threshold is a critical value used to judge the length of the usage time, and is summarized and set by those skilled in the art based on historical multiple experimental data;

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

[0076] If the usage duration value is greater than the usage duration threshold, it means that the usage duration of the medical supplies during the monitoring period is long, and a long usage duration signal is generated;

[0077] Obtain the monitoring period that generates the signal with a longer usage duration, and mark it as a high-duration monitoring period;

[0078] Obtain the number of high-duration monitoring cycles, perform ratio processing on the number of high-duration monitoring cycles and the total number of monitoring cycles to obtain the high-duration ratio;

[0079] Obtain the usage duration value of the high duration monitoring period, perform difference calculation between the usage duration value of the high duration monitoring period and the usage duration threshold value respectively 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, perform ratio calculation between the total usage duration deviation value and the usage duration threshold value to obtain the high duration degree value;

[0080] The high duration ratio value is multiplied by the high duration degree value to obtain the duration representation value;

[0081] It should be explained that the duration characterization value reflects the following meaning: the duration characterization value is calculated by the high duration ratio value and the high duration degree value, that is, the larger the high duration ratio value is, the more monitoring cycles corresponding to the signal with a longer duration are used, and the larger the duration characterization value is, that is, the larger the high duration degree value is, the higher the frequency of use of medical supplies is, that is, the larger the time degree value is, the larger the difference between the usage value corresponding to the high duration monitoring cycle and the usage duration threshold is, that is, the larger the time deviation degree is, the higher the frequency of use of medical supplies is;

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

[0083] In some embodiments, obtaining a frequency representation value and a duration representation value of a medical supply;

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

[0085] Compare the medical material usage value with the medical material usage threshold, wherein the medical material usage threshold is set by a technician in this field based on historical experimental data;

[0086] If the medical supplies usage value is less than or equal to the medical supplies usage threshold, it means that the medical supplies are not used at a high level, and a low-high usage signal is generated;

[0087] If the medical supplies usage value is greater than the medical supplies usage threshold, it means that the medical supplies are used at a high level, and a high usage signal is generated;

[0088] The technical solution of the embodiment of the present invention is mainly as follows: by obtaining the usage frequency value and usage duration value of medical supplies from historical data, calculating the usage frequency characterization value and usage duration characterization value based on the obtained usage frequency value and usage duration value, and then calculating the medical supply usage value, comparing the medical substance usage value with the medical substance usage threshold, and generating a high usage signal or a low usage signal, so that the usage degree of medical supplies can be judged based on historical data, and then more reasonably allocated based on the judgment result of the usage degree of medical supplies, thereby improving the utilization efficiency and management level of medical supplies.

[0094] Set EPC codes for high-use medical supplies. The coding structure that EPC codes can support includes but is not limited to batch information, serial number, and manufacturer code;

[0095] Exemplarily, the process of setting the user area is as follows:

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

[0097] Comparing the total amount of additional stored information with a threshold value of the total amount of additional stored information, wherein the threshold value of the total amount of additional stored information is set by a person skilled in the art based on a summary of multiple 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 be sufficient to store all necessary information, and the setting of the user area is canceled;

[0099] If the total amount of additional storage information is greater than the additional storage information threshold, the 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 the usage data of the EPC area, process it, calculate the usage judgment value, and compare it with the usage judgment threshold to determine the usage degree of the EPC area;

[0102] Among them, the usage data includes resource usage ratio and CPU usage ratio;

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

[0104] Obtain the resource usage of the EPC area at the end time of the detection period, and obtain the maximum resource capacity of the EPC area, where the maximum resource capacity is the maximum amount of resources that the EPC area can support;

[0105] The resource usage of the EPC area at the end of the detection period is compared with the maximum resource amount to obtain the resource usage ratio;

[0106] Obtain the total CPU usage time during the detection period, and perform ratio processing on the total CPU usage time during the detection period and the total time of the detection period to obtain the CPU usage ratio;

[0107] Substitute into the formula PD=s1*ZY+s2*PC to calculate the usage judgment value PD, where ZY represents the resource usage ratio, PC represents the CPU usage ratio, and s1 and s2 are preset proportional coefficients;

[0108] It should be explained that the usage judgment value reflects the following meaning: the usage judgment value is calculated by the resource usage ratio and the CPU usage ratio, that is, the larger the resource usage ratio, the larger the usage judgment value, and the higher the resource usage rate; that is, the larger the CPU resource ratio, the larger the usage judgment value, the higher the system load, and the higher the usage rate;

[0109] Compare the usage judgment value with the usage judgment threshold, wherein the usage judgment threshold is set by a person skilled in the art based on a summary of multiple historical experimental data;

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

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

[0112] Based on the generated high-frequency signals, optimization adjustments are made;

[0113] Optimization and adjustment measures include but are not limited to:

[0114] Dynamically adjust the size of the EPC area and the user area: Make 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 processing EPC area related operations, such as by optimizing algorithms, increasing cache or parallel processing;

[0116] The technical solution of the embodiment of the present invention is mainly as follows: by setting detailed EPC codes for medical supplies with high usage, including batch information, serial numbers and manufacturer codes, these supplies can be quickly identified and tracked, improving the efficiency of inventory management and logistics operations, and setting user areas to store additional maintenance information, usage records, validity periods, storage conditions, etc., so that managers can quickly obtain comprehensive information about the supplies, facilitating daily management and maintenance;

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