[0052] Step S104, determining a current electricity price period corresponding to the current time, and controlling the operation of the cold storage system according to a second operating temperature corresponding to the current electricity price period.

[0053] The control method for the operation of a cold storage system disclosed in the present invention determines the operating electricity cost of the cold storage system, and determines the operating temperature corresponding to each electricity price period according to the operating electricity cost and the parameters corresponding to each electricity price period, so as to control the operation of the cold storage system; the operating temperature of the cold storage system in each electricity price period can be automatically set, and the situation that the operating temperature is set unreasonablely due to relying on manual experience to set the operating temperature, which causes the operating temperature to be lower than the actual required operating temperature, resulting in problems such as excessive cold supply in the cold storage; the operating temperature and electricity consumption of the cold storage system can be accurately controlled, thereby reducing the energy consumption of the cold storage system; the electricity cost can be accurately controlled, thereby reducing the operation and maintenance costs of the cold storage system.

[0054] In some embodiments, the power grid can be divided into multiple electricity price periods according to the load changes of the power grid, and the electricity price periods of the power grid can be obtained through various existing methods. The electricity price periods may include: peak electricity price periods, valley electricity price periods, flat electricity price periods, etc.; and the electricity prices corresponding to the peak electricity price periods, valley electricity price periods, flat electricity price periods, etc. are different.

[0055] The first operating temperature can be set by the user according to the items stored in the cold storage system to meet the storage requirements of the items. The first operating temperature includes the peak operating temperature corresponding to the peak electricity price period, the valley operating temperature corresponding to the valley electricity price period, and the flat operating temperature corresponding to the flat electricity price period; among them, the peak operating temperature (the highest operating temperature of the cold storage)> the flat operating temperature> the valley operating temperature (the lowest operating temperature of the cold storage).

The second operating temperature includes an operating temperature corresponding to a peak power price period, a valley power price period, a flat power price period, etc.

[0057] By determining the parameters corresponding to peak electricity price periods, trough electricity price periods, and flat electricity price periods, the operating temperature, electricity consumption, etc. of the cold storage system during the peak electricity price periods, trough electricity price periods, and flat electricity price periods can be accurately controlled.

[0058] Figure 2FIG. 1 is a flow chart of determining the power consumption coefficient in some embodiments of the control method for the operation of the cold storage system according to the present disclosure, such as Figure 2 As shown:

[0059] Step S201, determining a power consumption coefficient corresponding to the electricity price period according to a first operating temperature corresponding to the electricity price period, power consumption and power consumption duration corresponding to the first operating temperature, and volume information.

[0060] The power consumption coefficient is an indicator that characterizes the power consumption of the cold storage system. Different cold storage systems may have different power consumption coefficients. By determining the power consumption coefficient of the cold storage system, the energy efficiency of the cold storage system can be determined. Based on the power consumption coefficient, the operating electricity fee, operating temperature and other information can be accurately determined. The power consumption coefficient of the cold storage system can be displayed so that users can know the energy consumption indicators of the cold storage system.

[0061] There are many methods for determining the power consumption coefficient corresponding to the electricity price period. For example, a first product of the first operating temperature and the power consumption, and a second product of the power consumption time and the volume information are calculated; and the quotient of the first product and the second product is used as the power consumption coefficient corresponding to the electricity price period.

[0062] By taking the power consumption of the cold storage system at the first operating temperature, corresponding to unit time and unit volume, as the power consumption coefficient of the cold storage system, the energy consumption level of the cold storage system can be accurately determined, and information such as the operating electricity fee and operating temperature can be accurately determined.

[0063] In some embodiments, the cold storage system includes a plurality of input modules, and the operator can input the volume information of the cold storage system through the input modules as the volume , the stored item information is type A, the storage type of the item is fresh-keeping or refrigeration, etc. The power consumption coefficient can be calculated when receiving the calculation instruction, or it can be calculated and stored in advance.

[0064] The cold storage system can automatically set the first operating temperature according to the stored item type information, etc.; the first operating temperature can also be manually set by the user through the input module. The first operating temperature includes: the peak operating temperature corresponding to the peak electricity price period, the valley operating temperature corresponding to the valley electricity price period, the flat operating temperature corresponding to the flat electricity price period, etc.; the peak operating temperature can be the highest operating temperature of the cold storage system The trough operating temperature can be the lowest operating temperature of the cold storage system. The flat operating temperature can be the normal operating temperature of the cold storage system .

[0065] The power consumption and power consumption duration corresponding to the first operating temperature may be determined in real time or in advance. For example, the power consumption and power consumption duration of the cold storage system at the first operating temperature may be collected in real time or in advance through a variety of power equipment, the power consumption may be the cumulative power consumption, and the power consumption duration may be the cumulative power consumption duration.

[0066] Power consumption refers to power consumption, which includes the maximum operating temperature of the cold storage. Corresponding W1 and the lowest operating temperature of the cold storage Corresponding W2, and normal operating temperature of cold storage Corresponding W3. The power consumption time includes: Corresponding T1 and the lowest operating temperature of the cold storage Corresponding T2, and normal operating temperature of cold storage Corresponding T3.

[0067] The power consumption coefficient calculation can be started by timing setting, automatic or manual. The first product of the first operating temperature and the power consumption is calculated as , calculate the second product of power consumption time and volume information as , the quotient of the first product and the second product is used as the power consumption coefficient corresponding to the electricity price period.

[0068] The formula for calculating the power consumption coefficient is as follows:

[0069] = (Formula 1);

[0070] in, is the nth first operating temperature; Wn is the power usage or power consumption corresponding to the nth first operating temperature, Tn is the power usage time corresponding to the nth first operating temperature; n is 1, 2, 3; V1 is the capacity of the cold storage system.

[0071] Will Substituting W1, T1 into formula 1, we can determine K1, which is the peak power consumption coefficient K corresponding to the peak electricity price period. 波峰 ;Will Substituting W2, T2 into formula 1, we can determine K2, which is the valley power consumption coefficient K corresponding to the valley electricity price period. 波谷 ;Will Substituting W3, T3 into formula 1, we can determine K3, which is the flat power consumption coefficient K corresponding to the flat electricity price period. 波平 .

[0072] Figure 3 FIG. 1 is a flow chart of determining the first operation electricity fee in some embodiments of the control method for the operation of the cold storage system according to the present disclosure, such as Figure 3 As shown:

[0073] Step S301, determining the electricity fee calculation parameters for each electricity price period according to the operation time and electricity price corresponding to each electricity price period.

[0074] Step S302: determining the sum of the electricity fee calculation parameters for all electricity fee time periods according to the electricity fee calculation parameters for each electricity fee time period.

[0075] Step S303: determining the total running time according to the running time corresponding to each electricity price period.

[0076] Step S304, determining a first parameter according to the sum of the electricity fee calculation parameters and the sum of the operating time.

[0077] Step S305 , determining the second parameter of each electricity price period according to the first operating temperature and power consumption coefficient corresponding to each electricity price period, and the volume information.

[0078] Step S306, calculating the product of the first parameter and the second parameter in each electricity price period to determine a plurality of first operating electricity charges.

[0079] Through the parameters corresponding to each electricity price period and the cold storage capacity, multiple first operating electricity charges are determined. Based on the multiple first operating electricity charges, the second operating electricity charges of the cold storage system can be reasonably set to avoid abnormal operation of the cold storage system due to unreasonable setting of the freight and electricity charges of the cold storage. The operating electricity charges of the cold storage system can be controlled, and the operation and maintenance costs of the cold storage system can be reduced.

[0080] There are many methods for determining the first parameter. For example, the quotient of the sum of the electricity cost calculation parameters and the sum of the operating time is calculated to determine the first parameter. By taking the quotient of the sum of the electricity cost calculation parameters and the sum of the operating time as the first parameter, the first parameter can characterize the average power consumption information of the cold storage system operation, which can improve the accuracy of the operation electricity cost determination.

[0081] There are many methods for determining the second parameter of each electricity price period. For example, the product of the power consumption coefficient and the volume information corresponding to each electricity price period is calculated, and the quotient of this product and the corresponding first operating temperature is calculated to determine the second parameter of each electricity price period. By taking the quotient of the product of the power consumption coefficient and the volume information and the corresponding first operating temperature as the second parameter, the second parameter can characterize the operating power consumption parameters of the cold storage system in each electricity price period, which can improve the accuracy of determining the operating electricity fee.

[0082] In some embodiments, the cold storage system can obtain the electricity price corresponding to each electricity price period through a variety of existing methods; the electricity fee can be determined by calculating the product of the electricity price and the power consumption or power usage. The electricity price period includes: peak electricity price period, valley electricity price period, flat electricity price period, etc. The electricity price includes: peak electricity price E1 corresponding to the peak electricity price period, valley electricity price E2 corresponding to the valley electricity price period, and flat electricity price E3 corresponding to the flat electricity price period.

[0083] The operating time corresponding to each electricity price period can be determined for a set period such as one day, one month, or two months. The operating time includes peak operating time T1 corresponding to the peak electricity price period, trough operating time T2 corresponding to the trough electricity price period, and flat operating time T3 corresponding to the trough electricity price period.

[0084] According to the peak operation time T1 and the peak electricity price E1 corresponding to the peak electricity price period, the electricity fee calculation parameter for the peak electricity price period is determined to be E1*T1; according to the valley operation time T2 and the valley electricity price E2 corresponding to the valley electricity price period, the electricity fee calculation parameter for the valley electricity price period is determined to be E2*T2; according to the flat operation time T3 and the valley electricity price E3 corresponding to the flat electricity price period, the electricity fee calculation parameter for the flat electricity price period is determined to be E3*T3.

[0085] According to the electricity cost calculation parameters of each electricity price period, the sum of the electricity cost calculation parameters of all electricity price periods is determined to be: E1*T1+ E2*T2+ E3*T3. According to the operating time corresponding to each electricity price period, the sum of the operating time is determined to be: T1+ T2+T3. According to the sum of the electricity cost calculation parameters and the sum of the operating time, the first parameter is determined to be: (E1*T1+ E2*T2+ E3*T3) / (T1+T2+ T3).

[0086] According to the first operating temperature and power consumption coefficient corresponding to each electricity price period, and the volume information, the second parameter of each electricity price period is determined. For example, the second parameter of the peak electricity price period is: (K 波峰 *V1) / C1; the second parameter of the valley electricity price period is: (K 波谷 *V1) / C2; the second parameter of the valley electricity price period is: (K 波平 *V1) / C3.

[0087] The formula for calculating the first running electricity fee is as follows:

[0088] = (Formula 2);

[0089] = (Formula 3);

[0090] = (Formula 4);

[0091] There are many ways to set the second operating electricity fee of the cold storage system. For example, among multiple first operating electricity fees, determine the maximum operating electricity fee and the minimum operating electricity fee; set the second operating electricity fee, where the maximum operating electricity fee> the second operating electricity fee> the minimum operating electricity fee. The user can manually set the second operating fee based on multiple first operating electricity fees; or automatically set the second operating fee by setting rules, and the setting rules can be multiple rules, for example, setting the second operating fee to the average of the maximum operating electricity fee and the minimum operating electricity fee, etc.

[0092] By determining the lowest operating electricity charge of the cold storage system and the highest operating electricity charge of the cold storage system among multiple first operating electricity charges, the operating electricity charge of the cold storage system can be reasonably set based on the lowest operating electricity charge and the highest operating electricity charge, thereby avoiding abnormal operation of the cold storage system due to unreasonable setting of freight and electricity charges. The operating electricity charge of the cold storage system can be controlled, thereby reducing the operation and maintenance costs of the cold storage system.

[0093] In some embodiments, the following can be determined based on the calculation results of the three first operating electricity charges: < , that is, the minimum operating electricity cost of the cold storage system is , the maximum operating electricity cost of the cold storage system is , the intermediate operation electricity cost of the cold storage system is The second operating electricity fee of the cold storage system within a set period of one day, one month, two months, etc. can be set to F, where < < .

[0118] Step S501, obtaining the light intensity of the current environment.

[0119] Step S502: determining whether the power supply mode of the cold storage system is a grid power supply mode or a photovoltaic power supply mode according to the light intensity.

[0120] By providing two power supply modes for the cold storage system, namely photovoltaic power supply mode and grid power supply mode, and selecting the mode according to the light intensity, the cold storage system can achieve a more energy-saving effect, reduce the grid power consumption of the cold storage system, and reduce the operation and maintenance costs of the cold storage system.

[0121] The cold storage system can be equipped with a photovoltaic power generation system or an independent photovoltaic power generation system. The use of a photovoltaic power generation system for power supply can reduce the power consumption of the cold storage system. When the power supply mode of the cold storage system is the photovoltaic power supply mode, the cold storage operating temperature corresponding to the photovoltaic power supply mode is obtained; based on the cold storage operating temperature, the operation of the cold storage system is controlled.

[0122] By setting the cold storage operating temperature and controlling the cold storage system operation according to the cold storage operating temperature, using the electricity of the photovoltaic system can reduce the grid electricity consumption of the cold storage system, and can reduce the operation and maintenance costs of the cold storage system.

[0125] In some embodiments, the cold storage system can have two power supply modes. The light intensity of the environment in which the cold storage system is located is detected by an existing light intensity detection device. If the light intensity is greater than the light intensity threshold a, it means that the electric energy provided by the photovoltaic power generation system can meet the power demand of the cold storage, and the power supply mode of the cold storage system is determined to be the photovoltaic power supply mode. The user can be reminded whether to switch to the photovoltaic power supply mode; if the light intensity is less than or equal to the light intensity threshold a, the power supply mode of the cold storage system is determined to be the grid power supply mode.

[0126] When it is determined that the power supply mode of the cold storage system is the photovoltaic power supply mode, determine whether the photovoltaic power generation system is operating normally. If the photovoltaic power generation system is operating normally, switch to the photovoltaic power supply mode. If the photovoltaic power generation system cannot operate normally, it prompts that the photovoltaic power supply mode switching has failed.

[0127] When the power supply mode of the cold storage system is the photovoltaic power supply mode, the cold storage operation temperature Ca corresponding to the photovoltaic power supply mode is obtained, and the operation of the cold storage system is controlled based on the cold storage operation temperature Ca.
