Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The present invention is described in further detail below with reference to specific examples, which are not to be construed as limiting the scope of the invention as claimed.
The method, the device and the computer equipment for determining the cold storage remaining use time period according to the embodiment of the invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for determining a remaining usage time period of cold storage according to an embodiment of the present invention, as shown in fig. 1, the method includes the steps of:
and S1, acquiring the total cooling capacity of the cold storage box at the initial moment.
The initial time may be a certain time when the cold storage tank is in a cold release stage. The total cold quantity at the initial moment is a known value, for example, when the cold storage box just starts to enter a cold release (heat preservation) stage, no cold quantity loss is generated, and the total cold quantity at the moment is the latent heat value of the cold storage material of the cold storage box. Of course, the initial time may be a certain time after the cold storage box releases the cold for a certain period of time, and the total cold amount at the initial time is the latent heat value minus the cold amount already released.
And S2, acquiring the released cold of the cold storage box at the current moment.
As shown in fig. 2, the method for acquiring the released cold amount of the cold storage box at the current moment specifically includes the following steps:
and S21, acquiring the temperature difference between the inside and the outside of the cold storage box at the current moment.
Thermometers are respectively arranged inside and outside the cold storage box. The thermometer arranged in the cold storage box is used for detecting the internal temperature of the cold storage box, and the thermometer arranged outside the cold storage box is used for detecting the external temperature of the cold storage box. One or more thermometers may be provided. When a plurality of thermometers are provided, the internal temperature or the external temperature of the cold storage tank is an average value of the plurality of thermometers. The position where the thermometer is disposed is not limited.
After the internal temperature and the external temperature of the cold storage box at the current moment are obtained through detection, the temperature difference value between the inside and the outside of the cold storage box at the current moment can be obtained through calculation.
And S22, acquiring the initial time and the current time of cold charging of the cold storage box.
And S23, acquiring the cold release coefficient of the cold storage box.
Wherein, the cold release coefficient is related to at least one of the heat exchange area, the material heat conductivity coefficient and the box body thickness of the cold storage box.
And S24, determining the released cold quantity according to the cold releasing quantity in unit time, the temperature difference between the inside and the outside of the cold storage box, the initial time, the current time and the cold releasing coefficient.
The unit time cold release amount is the unit time cold release amount per degree centigrade and is an empirical value obtained through multiple measurements or experiments.
In one embodiment of the invention, the released cold amount of the cold storage box at the current moment can be obtained based on the formula I.
The formula I is as follows: the cold-releasing quantity of the cold-storage box at the current moment is (the current moment-the initial moment) and the temperature difference between the inside and the outside of the cold-storage box at the current moment is the cold-releasing quantity per unit time and the cold-releasing coefficient
And S3, acquiring the environmental coefficient corresponding to the cold storage box.
The environment coefficient corresponding to the cold storage box is related to at least one of season information, altitude information and motion state.
And S4, determining the residual cold capacity of the cold storage box according to the total cold capacity, the released cold capacity and the environmental coefficient.
In one embodiment of the invention, the residual cold capacity of the cold storage box can be obtained by calculation based on the formula two.
The formula II is as follows: the residual cold quantity of the cold storage box is the total cold quantity-released cold quantity and the environmental coefficient
And S5, acquiring the unit time cold release amount of the cold storage box.
The unit time cold release amount is the unit time cold release amount per degree centigrade and is an empirical value obtained through multiple measurements or experimental calculations.
And S6, determining the cold accumulation residual service time according to the residual cold quantity and the unit time cold release quantity.
Specifically, the cold storage remaining use time period can be obtained based on the formula three calculation.
The cold accumulation residual service time is equal to the residual cold quantity/unit time cold release quantity.
After the remaining service life is calculated, the time when the remaining cold energy is used up can be known, the cold storage box can be charged and cooled in time, and the phenomena that the transported goods are deteriorated due to the fact that the cold energy in the cold storage box is used up are avoided.
According to the method for determining the cold accumulation remaining use time of the embodiment of the invention, the cold accumulation is intelligently managed by acquiring the total cold amount of the cold accumulation box at the initial time, acquiring the released cold amount of the cold accumulation box at the current time, acquiring the environment coefficient corresponding to the cold accumulation box, determining the remaining cold amount of the cold accumulation box according to the total cold amount and the released cold amount, then acquiring the unit time cold release amount of the cold accumulation box, and finally determining the cold accumulation remaining use time according to the remaining cold amount and the unit time cold release amount.
In addition, in another embodiment of the present invention, as shown in fig. 3, the acquiring of the cold release coefficient of the cold storage tank may include the steps of:
and S25, judging whether the residual cold of the cold storage box is larger than a preset value.
Wherein the predetermined value may be a specific value, such as 500; may also be present, such as 50%.
Before the cold release coefficient of the cold storage box is obtained, whether the residual cold quantity of the cold storage box is larger than a preset value or not is judged. And selecting different cooling coefficients according to the judgment result.
And S26, if the residual cold capacity of the cold storage box is larger than the preset value, taking the first cold release coefficient as the cold release coefficient.
And S27, if the residual cold quantity of the cold storage box is smaller than the preset value, taking the second cold release coefficient as the cold release coefficient.
The data of a plurality of experiments show that the residual cold quantity of the cold storage box is gradually released, and the cold release coefficient of the cold storage box changes when the residual cold quantity is smaller than a certain value. In one embodiment of the invention, in order to improve the calculation accuracy, when the residual cold capacity of the cold storage box is greater than a preset value, a first cold release coefficient can be selected as the cold release coefficient; when the residual cold quantity of the cold storage box is smaller than a preset value, the second cold release coefficient can be selected as the cold release coefficient. By the method, the released cold quantity of the cold storage box at the current moment can be acquired more accurately, and the accuracy of determining the remaining cold storage use duration is further improved.
