The present invention aims to solve at least one of the technical problems existing in the prior art; therefore, the invention provides a medical consumable cold chain transportation monitoring method based on the Internet of things, which is used for solving the technical problems that the prior art cannot monitor the whole process of medical consumable cold chain transportation, and the medical consumable using effect is affected because the medical consumable cold chain transportation is difficult to discover and trace in time aiming at irregular operation.
To achieve the above object, a first aspect of the present invention provides a medical consumable cold chain transportation monitoring method based on the internet of things, including: determining a transportation route, identifying the transportation route and sequentially extracting a plurality of key links; sequentially matching qualified operators for a plurality of key links, and carrying out hash calculation on the key links and the personnel identifications of the operators to obtain a basic hash value; identifying the current key link and marking the current key link as a target link; verifying an operator of the target link, performing whole-course monitoring on the temperature and humidity of the target link after the verification is passed to obtain an environment monitoring coefficient, performing analysis and correlation on a personnel verification result of the target link and the environment monitoring coefficient, and performing hash calculation to obtain a link hash value; integrating and splicing the basic hash value and the acquired link hash value to acquire a transportation hash value; and the transportation hash value is timely expanded in the subsequent transportation process, and meanwhile, the transportation hash value is stored in a uplink manner.
At present, in the cold chain transportation process of medical consumables, only main transportation links are generally monitored, for example, the temperature and humidity of a warehouse are monitored when the medical consumables are in the warehouse, and the temperature and humidity in a refrigerator car are monitored when the medical consumables are on the refrigerator car; the monitoring of some secondary transportation links of medical consumables in the cold chain transportation process is omitted, such as the monitoring is rarely performed in the medical consumable transportation process. Medical consumables need to last and strict assurance humiture requirement in cold chain transportation, otherwise can cause medical consumables's unusual, influence result in use.
The invention has the main contribution that the transportation route is subdivided, the whole process of monitoring is carried out on the transit link, the transportation link and the warehouse-in and warehouse-out link in the transportation route, and the monitoring results of all key links in the transportation route are stored in a chain way. The invention not only realizes the whole-process monitoring of the cold chain transportation of medical consumables, but also can ensure the safety of monitoring data and is beneficial to the later-stage tracing.
The key links in the invention comprise a transfer link, a transportation link, a warehouse-in and warehouse-out link and the like. The transfer link can be understood as a transfer link of medical consumables; if the transportation route is longer, medical consumables need to be transported in a warehouse, and the transportation process involves a transportation link and staff. The transportation link can be understood as a transportation link in which medical consumables are in a cold chain car. The ex-warehouse link can be the link of ex-warehouse transportation and warehouse storage of medical consumables immediately. The transit link and the transportation link are inserted between the access link and the warehouse-in link to form a complete medical consumable cold chain transportation route, so that the whole-process monitoring is completed.
The method mainly monitors the temperature and the humidity in the cold chain transportation of medical consumables, and judges that the whole cold chain transportation process meets the requirements when the temperature and the humidity are in a qualified state all the time; otherwise, early warning is carried out on unqualified key links, and whether medical consumables are damaged or not needs to be detected after early warning. In other preferred embodiments, other environmental factors besides temperature and humidity may also be monitored.
Many data can be obtained in the cold chain transportation process of medical consumables, and a large amount of storage space can be occupied if the data are directly stored in a uplink mode, and comparison difficulty can be increased during comparison.

One of the transportation routes is selected as a final cold chain transportation route, and the main basis of the selection is transportation characteristics including the number of times of transfer, the transportation distance, the transportation time effect and the like, for example, the smaller the number of times of transfer, the shorter the transportation distance, the transportation time effect meets the transportation requirement, and the corresponding transportation route is optimal.
After the transport route is determined, the cold chain transport process of the medical consumable is simulated, and whether the medical consumable needs to change the transport environment or transport equipment is judged. If the process transferred from the transport device A to the transport device B belongs to the change of the transport process, the process belongs to the transfer link; the process of transporting from the transport device B to the destination warehouse belongs to the terminal of the transport process, which belongs to the warehousing link. Therefore, the transportation route can be divided into a plurality of key links, and the key links are marked with numbers in turn to be used as link identifiers thereof.
Preferably, the matching of the qualified operators for the key links sequentially performs hash calculation on the key links and the personnel identifiers of the operators to obtain a basic hash value, including: sequentially extracting key links, and matching at least one qualified operator for the key links; taking the biological characteristics of the matched operators as personnel identifications; link identifiers of key links are associated and integrated with personnel identifiers, and link association characteristics are obtained; and after link association features of the transportation route corresponding to a plurality of key links are spliced in sequence, calculating and obtaining a basic hash value.
After each key link is determined, if the key link needs staff assistance, qualified staff is matched for the key link. Qualified staff means staff trained in cold chain transportation profession and the training result reaches the standard, so that influences of non-professional behaviors of the staff on the transportation process are avoided. After matching the staff, the biological characteristics of the staff need to be extracted; biometric features are generated based on the facial image or fingerprint image of the operator, such as facial features in the facial image or fingerprint features in the fingerprint image, if authorized; the facial features and fingerprint features are digitized and then used as personnel identification.

Therefore, the two are compared to obtain the environmental monitoring coefficient.

If the transportation link is stable and the duration time is long, the sampling period can be relatively set larger; the transfer link lasts for a period of time and the working environment is unstable, and the adoption period can be relatively small.
Preferably, the comparing the temperature and humidity in the first environmental data and the second environmental data, and calculating to obtain an environmental monitoring coefficient according to the temperature and humidity comparison result of the target link includes: calculating a temperature difference absolute value WCJ and a humidity difference absolute value SCJ in the environmental data I and the environmental data II; obtaining an environment monitoring coefficient HJX through the calculation of the formula HJX=alpha 1×| WCJ-BWCJ|+alpha 2×|SCJ-BSCJ|; where α1 and α2 are empirically set weight coefficients, α1+α2=1, bvcj and BSCJ are the temperature and humidity of a standard transportation environment, respectively.
Preferably, the step of analyzing and correlating the personnel verification result and the environment monitoring coefficient of the target link and performing hash calculation to obtain a link hash value includes: setting a personnel verification identifier for a personnel verification result of the target link, and setting an environment monitoring identifier when an environment monitoring coefficient of the target link is smaller than an environment monitoring threshold value; and performing association splicing on the personnel verification mark and the environment monitoring mark and the link mark of the target link, and obtaining a hash value of a splicing result through hash calculation, and marking the hash value as the link hash value.
The method comprises the steps of firstly verifying staff in a target link, and setting a staff verification mark according to a verification result, wherein if the staff verification mark is 1, the staff verification mark indicates that verification is passed, and if the staff verification mark is 0, the staff verification mark indicates that verification is not passed. When the target link comprises a plurality of environment monitoring coefficients, calculating the average value of the environment monitoring coefficients, and when the average value of the environment monitoring coefficients is smaller than an environment monitoring threshold value, setting the environment monitoring identifier to be 1, otherwise, setting the environment monitoring identifier to be 0.

After the transportation route and the staff member in the invention are determined, the basic hash value is not changed. However, the link hash value is continuously increased along with the continuous monitoring, so that the transportation hash value is also continuously expanded along with the continuous monitoring process. Finally, the transport hash value is stored in a uplink mode, and the completion of cold chain transport of medical consumables is indicated.

And if the transportation distances of the three transportation routes are consistent, the number of times of transfer is small, and the transportation time efficiency meets the transportation requirement, the transportation route [2, 100, 20] is optimal, and the transportation route is marked as a route A.
Taking the route A as an example, the corresponding key links are a delivery link, a transportation link 1, a transfer link 1, a transportation link 2, a transfer link 2, a transportation link 3 and a warehouse-in link, that is, six key links exist in total. Each key link is correspondingly matched with at least one qualified worker; if the warehouse-out link and the warehouse-in link can be configured with two qualified staff, the transportation link 1 and the transportation link 2 can be matched with a qualified cold chain transportation driver.

According to the calculation formula of the environment monitoring coefficients, two environment monitoring coefficients corresponding to the target link can be calculated, and the average value of the two environment monitoring coefficients can be used as the final environment monitoring coefficient. When the environment monitoring coefficient is smaller than the environment monitoring threshold value, marking the environment monitoring mark as 1, otherwise marking as 0; and setting the personnel verification identification to 1 when the personnel verification passes, and setting to 0 otherwise. And if both the two are in accordance with the requirements, the link hash value of the target link can be obtained by the calculation of [3,1 ].
The third step of this embodiment is to integrate and splice the basic hash value and the obtained link hash value to obtain a transport hash value; and the transportation hash value is timely expanded in the subsequent transportation process, and meanwhile, the transportation hash value is stored in a uplink manner.
And expanding the transportation hash value once every time a link hash value is obtained. After medical consumables are put in storage, the whole cold chain transportation flow is completed, the transportation hash value is not changed, and the medical consumables are stored in a chain. Any suitable method can grasp the state of the medical consumable transportation flow through the transportation hash value.
The partial data in the formula are all obtained by removing dimension and taking the numerical value for calculation, and the formula is a formula closest to the real situation obtained by simulating a large amount of collected data through software; the preset parameters and the preset threshold values in the formula are set by those skilled in the art according to actual conditions or are obtained through mass data simulation.
