Technical Field

The invention relates to the technical field of product quality control, in particular to a method and a system for controlling agricultural products.

Quilt scenery technology

The quality guarantee period of various commodities is long, the quality guarantee period of agricultural products is long, and the quality and the safety of the products can be guaranteed only when the agricultural products are used in the quality guarantee period. However, the determination of shelf life usually refers to the longest storage time under ideal temperature environment, but in practice, the storage environment may change, for example, the product may go through several stages of picking, packaging, transporting, storing, exhibiting, and the like, and the environmental temperature of each stage may be different, even in the same stage, for example, the environmental temperature of the product may increase due to too long time during the transporting process. Variations in temperature can affect the actual shelf life of a product, and thus, currently, determining the remaining shelf life of a product based on shelf life in an ideal temperature environment is inaccurate. There are instances where the product has substantially deteriorated but is still within a calculated shelf life.

Disclosure of Invention

The invention aims to solve the problem that the residual quality guarantee time of a product is inaccurate in the prior art, and provides an agricultural product quality control method and system to improve the accuracy of the residual quality guarantee time of the product and further guarantee the use safety of the product.

In order to achieve the above object, the embodiments of the present invention provide the following technical solutions:

in one aspect, an embodiment of the present invention provides a method for controlling agricultural products, including the following steps:

collecting the storage environment temperature of the agricultural products in real time, and recording the corresponding relation between the temperature and the time;

based on the corresponding relation between the temperature and the time, calculating the storage time of the agricultural products according to a strategy that the timing step length changes along with the temperature change;

calculating a remaining shelf life of the agricultural product based on the storage time.

In the scheme, the storage environment temperature of the agricultural product is collected in real time, the timing step length is not fixed but changes along with the change of the temperature, for example, the step length is shortened when the temperature rises, namely the recorded storage time is smaller than the actual storage time, so that the recorded storage time corresponds to the deterioration speed of the product, the recorded storage time is more accurate, and the quality guarantee remaining time calculated based on the recorded storage time is more accurate, so that the use safety of the product can be guaranteed, and the condition that the product is actually deteriorated but the quality guarantee period is not reached is avoided.

In a further preferred embodiment, in the step of acquiring the storage environment temperature of the agricultural product in real time, an average temperature of a plurality of temperature sensors respectively disposed at different positions is obtained as the acquired temperature.

In the above scheme, a plurality of temperature sensors are arranged at different positions, and the average value of the temperature sensors is finally obtained, so that the temperature measurement result is more accurate, and the timing step length which changes based on the temperature change is more accurate.

The strategy of the timing step length changing along with the temperature change is as follows: when the temperature is less than the lower threshold, the timing step becomes longer as the temperature decreases, and when the temperature is greater than the upper threshold, the timing step becomes shorter as the temperature increases.

In general, the lower the temperature, the slower the product deteriorates, whereas the higher the temperature, the easier it deteriorates, so the strategy of timing step changes with temperature changes in the above scheme can further improve the accuracy of the recorded storage time.

In one embodiment, the lower threshold and the upper threshold are respectively a temperature value, and the timing step is T0+ T when the temperature is less than the lower threshold, T0 when the temperature is greater than or equal to the first threshold and less than or equal to the upper threshold, and T0-T' when the temperature is greater than the second threshold.

In another embodiment, the lower threshold and the upper threshold are two temperature values, the lower threshold includes a first threshold and a second threshold, the upper threshold includes a third threshold and a fourth threshold, when the temperature is less than the first threshold, the timing step is T0+ T1, and when the temperature is greater than or equal to the first threshold and less than the second threshold, the timing step is T0+ T2, T1 is not equal to T2; when the temperature is greater than or equal to the second threshold and less than or equal to the third threshold, the timing step is T0; when the temperature is greater than the third threshold and less than or equal to the fourth threshold, the timing step is T0-T3, and when the temperature is greater than the fourth threshold, the timing step is T0-T4, and T4 ≠ T3.

The former solution is relatively simpler to operate, and simplifies the algorithm while improving the accuracy of the storage time record. The latter solution is relatively more complex to operate, but the timing steps are more finely varied, which may further improve the accuracy of the time-of-reserve recording.

On the other hand, the present invention also provides an agricultural product quality control system for implementing the agricultural product quality control method according to any one of the embodiments of the present invention, including:

the temperature sensor is used for acquiring the storage environment temperature of the agricultural product in real time and recording the corresponding relation between the temperature and the time;

and the processing system is used for measuring and calculating the storage time of the agricultural products according to the corresponding relation between the temperature and the time and the strategy that the timing step length is changed along with the temperature change, and calculating the quality guarantee residual time of the agricultural products based on the storage time.

In another aspect, the present invention provides an agricultural product quality control system in another embodiment, including:

the electronic tag is arranged on the agricultural product and used for recording the identity information of the agricultural product;

the temperature sensor is used for acquiring the storage environment temperature of the agricultural products in real time;

the timer is used for measuring the storage time of the agricultural products, and the timing step length of the timer is changed along with the change of the temperature;

and the quality control device is used for calculating the remaining quality guarantee time of the agricultural product based on the storage time and establishing the corresponding relation between the identity information of the agricultural product and the remaining quality guarantee time.

In another aspect, the present invention further provides a method for controlling agricultural products, comprising the following steps:

constructing a corresponding relation that the quality guarantee duration of the agricultural products changes along with the temperature change through testing;

and acquiring the current storage environment temperature of the agricultural products in real time, and measuring and calculating the quality guarantee duration of the agricultural products based on the current storage environment temperature based on the corresponding relation that the quality guarantee duration changes along with the temperature change.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the present embodiment provides a method for controlling agricultural products, including the following steps:

and S10, collecting the storage environment temperature of the agricultural products in real time, and recording the corresponding relation between the temperature and the time.

The storage environment temperature is collected, one temperature sensor can be used, when the storage environment is wide or not based on cost, a plurality of temperature sensors are preferably adopted and are respectively arranged at different positions, so that the average value of the plurality of temperature sensors can be taken as the finally collected storage environment temperature value.

The temperature sensor adopted in the embodiment not only needs to have a temperature acquisition function, but also needs to have a timing function, so that the acquisition time can be recorded while the temperature is acquired, and the corresponding relation between the temperature and the time can be obtained. The product can be purchased directly from the market, and a timing module or a network module can be additionally arranged in a common temperature sensor to acquire time information through a network.

And S20, calculating the storage time of the agricultural products according to the corresponding relation between the temperature and the time and the strategy that the timing step changes along with the temperature change.

Generally, the deterioration of the product is accelerated with increasing temperature, and therefore, the strategy adopted in this step is: when the temperature is less than the lower threshold, the timing step becomes longer as the temperature decreases, and when the temperature is greater than the upper threshold, the timing step becomes shorter as the temperature increases.

That is, the time history is slower when the temperature is lower because the deterioration of the product is also slow or does not deteriorate, and the time history is faster when the temperature is higher, so the deterioration of the product is also faster. That is, by the strategy in this step, it is achieved that the recorded storage time changes synchronously (or tends to be synchronously) with the deterioration rate of the product, so that the recorded storage time and the deterioration time of the product tend to coincide.

And S30, calculating the shelf life of the agricultural product based on the storage time.

Here, the remaining shelf life is defined as t, t0 is an ideal shelf life, i.e., the longest storage time in an ideal temperature environment, t 'is a storage time, i.e., the storage time measured in step S20, and thus t is t 0-t'. For example, if the ideal shelf life is 180 days and the recorded storage time is 15 days (perhaps only 13 days in actual storage), the remaining shelf life is 180-15-165 days.

The invention utilizes the principle that the higher the temperature is, the more rapid the deterioration is, so that for the storage time of the product, the real storage time of the product is not recorded, namely the real time based on Beijing time, but the storage time is measured and calculated based on the change of the temperature along with the time, and then the estimation of the shelf life residual time based on the measured and calculated storage time is more reasonable and more accurate.

Since the solution requires the arrangement of a temperature sensor in the storage environment to detect the temperature of the storage environment, it is possible to perform the method only in some storage environments, such as the storage environment during transportation, if there are conditions lacking in some storage environments of the product (e.g. storage in the home environment, temperature sensors are not purchased due to cost considerations), since generally fixed storage environments are relatively suitable environments, but during transportation, especially in the case of relatively long transportation time, the storage temperature is not easily controlled and varies greatly, and therefore it is recommended that the method be preferably used for recording the storage time and calculating the remaining shelf life in the storage environment during transportation.

There are various ways to implement the timing step as a function of temperature, and two relatively suitable ways are listed herein.

The first method is as follows: the lower threshold and the upper threshold are respectively a temperature value, when the temperature is less than the lower threshold, the timing step is T0+ T, when the temperature is greater than or equal to the first threshold and less than or equal to the upper threshold, the timing step is T0, and when the temperature is greater than the second threshold, the timing step is T0-T'.

This is the simplest way, the temperature is roughly divided into 3 temperature intervals, T0 is the basic step length, T and T 'may be equal or unequal, the division values may be different based on different products or temperature intervals, and the specific values of T and T' need to be tested before implementing the present solution. For example, for a certain product, the shelf life of the product at different temperatures is tested through multiple tests, each test obtains a corresponding relation between the shelf life and the temperature, then the corresponding relation between the shelf life and the temperature is obtained through multiple fitting, a change curve of the temperature and the shelf life is obtained, for example, a curve of the shelf life changing along with the temperature is obtained by taking the temperature as an abscissa and the shelf life as an ordinate, the more times of the tests are, the more accurate the curve is obtained through the fitting, and for example, the obtained curve function is y ═ ax²+ bx + c, where a, b, c are constants respectively, and a is less than 0, y is the shelf life, and x is the temperature. Based on the curve function, T and T' can be determined. For example,x₀the ideal storage environment temperature is the corresponding temperature x when the time is counted according to the timing step T0₁Is a lower threshold value, x₂Is the upper threshold.

For example, the lower threshold is-5 deg.C, the upper threshold is 10 deg.C,i.e. every 1 second is timed asMinutes, then when the temperature is less than-5 c,i.e. every 1 second is timed asMinute, that is, the storage time is actually (based on Beijing time) 60 minutes, but the storage time is recordedThe storage time of the records isAnd (3) minutes. And when the temperature is more than 10 c,i.e. every 1 second is timed asMinute, i.e., 60 minutes of actual storage (based on Beijing time), but 90 minutes of storage time was recorded.

The second method comprises the following steps: the lower limit threshold and the upper limit threshold are two temperature values respectively, the lower limit threshold comprises a first threshold and a second threshold, the upper limit threshold comprises a third threshold and a fourth threshold, when the temperature is less than the first threshold, the timing step length is T0+ T1, when the temperature is greater than or equal to the first threshold and less than the second threshold, the timing step length is T0+ T2, and T1 is not equal to T2; when the temperature is greater than or equal to the second threshold and less than or equal to the third threshold, the timing step is T0; when the temperature is greater than the third threshold and less than or equal to the fourth threshold, the timing step is T0-T3, and when the temperature is greater than the fourth threshold, the timing step is T0-T4, and T4 ≠ T3.

Compared with the first mode and the second mode, the temperature range gradient is divided more finely, and the timing step gradient is also divided more finely. Generally, when T1/T2/T3/T4 are all positive integers, T2 < T1 and T3 < T4, because the deterioration is faster with increasing temperature. However, if one considers that for some products, too low a temperature would otherwise freeze the product out, then T2 may be greater than T1, but T3 is still less than T4.

On the basis of the second mode, it is easy to understand that the temperature range gradient can be set to be finer, and then the timing step gradient can be set to be finer.

As shown in fig. 2, the hardware system required for implementing the method includes:

and the temperature sensor is used for acquiring the storage environment temperature of the agricultural products in real time and recording the corresponding relation between the temperature and the time. The temperature sensor is preferably provided in plural numbers, and is provided at different positions in the storage environment.

And the processing system is used for measuring and calculating the storage time of the agricultural products according to the corresponding relation between the temperature and the time and the strategy that the timing step length is changed along with the temperature change, and calculating the quality guarantee residual time of the agricultural products based on the storage time.

As shown in fig. 3, based on the similar inventive concept of the method shown in fig. 1, the present embodiment provides another agricultural product quality control system, which includes:

the electronic tag is arranged on the agricultural product and used for recording the identity information of the agricultural product;

the temperature sensor is used for acquiring the storage environment temperature of the agricultural products in real time;

the timer is used for measuring the storage time of the agricultural products, and the timing step length of the timer is changed along with the change of the temperature;

and the quality control device is used for calculating the remaining quality guarantee time of the agricultural product based on the storage time and establishing the corresponding relation between the identity information of the agricultural product and the remaining quality guarantee time.

In the system, the temperature sensor only needs to have a temperature acquisition function, but the timer not only needs to have a timing function and work synchronously with the temperature sensor, but also needs to have a function that the timing step changes along with the temperature change, namely the timer is provided with a timing module and a processing module, the timing module executes timing operation, and the processing module executes the operation that the timing step changes along with the temperature change.

When the timer implements a function in which the timing step varies with a change in temperature, for example, when the temperature is less than the lower threshold, the timing step becomes longer as the temperature decreases, and when the temperature is greater than the upper threshold, the timing step becomes shorter as the temperature increases. For a specific implementation manner, reference may be made to the foregoing first or second exemplary implementation manners, or other implementation manners.

After the corresponding relation of the shelf life time of the product changing along with the temperature change is constructed through testing, not only can T and T' (and T1/T2/T3/T4) be determined, but also the shelf life time of the product at the current storage environment temperature can be determined based on the corresponding relation, namely after the current storage environment temperature of the agricultural product is acquired in real time, the shelf life time of the agricultural product based on the current storage environment temperature can be measured and calculated based on the corresponding relation of the shelf life time changing along with the temperature change. It can also be understood that, as shown in fig. 4, another agricultural product quality control method is provided in the present embodiment, including:

s100, constructing a corresponding relation that the quality guarantee duration of the agricultural products changes along with the temperature change through testing;

s200, collecting the current storage environment temperature of the agricultural product in real time, and calculating the quality guarantee duration of the agricultural product based on the current storage environment temperature based on the corresponding relation that the quality guarantee duration changes along with the temperature change.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
