It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0050] In this embodiment, a method for controlling the power consumption of a refrigeration device is provided. This embodiment uses the application of this method to a computer device as an example for illustration. It can be understood that this method can also be applied to a server, and can also be applied to a system including a computer device and a server, and can be implemented through the interaction between the computer device and the server.

[0051] Figure 1 This is a flowchart illustrating the power control method for refrigeration equipment provided in an embodiment of this application. This method is applied to computer equipment or servers. In one embodiment, such as... Figure 1 As shown, it includes the following steps:

[0052] S101, obtain historical electricity consumption data for multiple historical unit periods in the target area.

[0053] The target area refers to the region where the power consumption of the refrigeration equipment needs to be controlled; for example, the target area could be a city or a country. The unit cycle is a preset unit time period, typically 24 hours per day.

[0054] S102, analyze historical electricity consumption data for different periods in multiple historical unit cycles to determine the electricity consumption level for different periods within a unit cycle.

[0055] A unit cycle can be divided into multiple different time periods, such as one hour per time period. Electricity consumption level is a parameter reflecting the amount of electricity consumed in different time periods within a unit cycle. In some embodiments, electricity consumption level can be divided into peak periods, off-peak periods, and valley periods. Peak periods correspond to the highest electricity consumption, followed by off-peak periods, then valley periods, and finally valley periods.

[0056] S103, sort the electricity consumption degrees of different time periods, and select a plurality of first target time periods from all time periods according to the electricity consumption degrees from low to high.

[0057] In the embodiment, the time period with a low electricity consumption degree is selected as the first target time period, the electricity peak can be avoided, the power failure caused by insufficient electricity can be avoided, and the start of the refrigeration equipment can be affected.

[0058] S104, determine the required start duration of the refrigeration equipment in a unit period according to the required space refrigeration temperature of the refrigeration space provided by the refrigeration equipment, and the refrigeration equipment is in the target region.

[0059] The refrigeration equipment is a device for refrigeration, and the refrigeration equipment includes a compressor, an air conditioner, a refrigerator, and a fan. The refrigeration space is a space that needs to be refrigerated, and the refrigeration space includes a refrigerated warehouse, a freezer, and a space in a refrigerator.

[0060] In order to make the refrigeration space reach the required space refrigeration temperature or maintain a certain space temperature, the refrigeration equipment does not need to be started all the time, the required start duration of the refrigeration equipment in a unit period is obtained, and the waste of energy can be avoided.

[0061] S105, determine whether the required start duration is greater than the accumulated duration corresponding to the plurality of first target time periods, and in the case of being greater, all the first target time periods are removed from all the time periods, and the second target time period is determined from the time periods remaining after the removal.

[0062] In the embodiment, the required start duration is greater than the accumulated duration corresponding to the plurality of first target time periods, at this time, the refrigeration equipment is controlled to be started only according to the plurality of first target time periods, the refrigeration space cannot be guaranteed to reach the required space refrigeration temperature, the goods stored in the refrigeration space may be deteriorated or damaged, and economic losses may be caused.

[0063] In one embodiment, in the case of being not greater, the electricity cost data of each first target time period is obtained; the electricity cost data of different first target time periods is sorted, and the first target time period is removed from all the first target time periods according to the electricity cost data from high to low; and the refrigeration equipment is controlled to be started according to the first target time period remaining after the removal.

[0064] The size of the electricity cost data corresponds to the high and low of the electricity consumption degree, and the corresponding relationship is that the higher the electricity consumption degree, the larger the electricity cost data; the lower the electricity consumption degree, the smaller the electricity cost data.

[0065] In the embodiment, the time period with low electricity cost data is selected as the first target time period, and the refrigeration equipment is controlled to be started according to the first target time period, so that the electricity cost and the electricity consumption loss can be reduced.

[0066] S106, controlling the refrigeration equipment to start according to the first target time period and the second target time period.

[0067] The method for controlling power consumption of the refrigeration equipment provided in the embodiment comprises the following steps: obtaining historical power consumption data of a plurality of historical unit periods in a target region where the refrigeration equipment is located; analyzing the historical power consumption data of different time periods in the plurality of historical unit periods to determine power consumption degrees of different time periods in a unit period; determining a plurality of first target time periods according to the power consumption degrees of different time periods; determining a required starting duration of the refrigeration equipment in the unit period according to a required space refrigeration temperature of a refrigeration space provided by the refrigeration equipment; in a case where the required starting duration is greater than an accumulated duration corresponding to the plurality of first target time periods, eliminating all the first target time periods from all time periods, and determining a second target time period from time periods remaining after the elimination; and controlling the refrigeration equipment to start according to the first target time period and the second target time period. Compared with the traditional technology of controlling the temperature in the refrigeration space by artificially controlling the start and stop of the refrigeration equipment, the application analyzes the historical power consumption data of the target region where the refrigeration equipment is located to determine the power consumption degrees of different time periods, and then determines the plurality of first target time periods according to the power consumption degrees of different time periods. In a case where the required starting duration of the refrigeration equipment is greater than the accumulated duration corresponding to the plurality of first target time periods, the second target time period is determined from the time periods remaining after the elimination of all the first target time periods from all time periods. The refrigeration equipment is controlled to start according to the first target time period and the second target time period, so that the refrigeration space can reach the required space refrigeration temperature, the power consumption loss is reduced, and the energy utilization rate is improved.

[0068] In one embodiment, the process of analyzing the historical power consumption data of different time periods in the plurality of historical unit periods to determine the power consumption degrees of different time periods in a unit period comprises the following steps: Figure 2 as shown in FIG. 1, comprising the following steps:

[0069] S201, determining power consumption curves corresponding to each historical unit period according to the historical power consumption data of different time periods in each historical unit period.

[0070] In some embodiments, the power consumption curves corresponding to each historical unit period are drawn by using the historical power consumption data of different time periods in each historical unit period.

[0071] In some other embodiments, the historical power consumption data of different time periods in each historical unit period is filtered by principal component analysis, and the power consumption curves corresponding to each historical unit period are drawn by using the filtered historical power consumption data.

[0072] S202, fitting each power consumption curve to obtain a target power consumption curve, and taking the power consumption data of different time periods on the target power consumption curve as the power consumption degrees of different time periods in a unit period.

[0073] In the embodiment, the least square method is used to fit each power consumption curve to obtain the target power consumption curve. According to the target power consumption curve, the power consumption degree of different time periods in a unit period is determined, which can improve the accuracy of the determined power consumption degree of different time periods.

[0074] In one embodiment, in a unit period, the refrigeration space is brought to or maintained at the required space refrigeration temperature by the refrigeration equipment, and the required starting time of the refrigeration equipment is determined. The flowchart of the determination method is shown in FIG. 1, which includes the following contents: Figure 3

[0075] S301, the historical initial temperature of the refrigeration space provided by the refrigeration equipment before starting is integrated to obtain a target historical initial temperature.

[0076] The way of integrating the historical initial temperature of the refrigeration space provided by the refrigeration equipment before starting to obtain a target historical initial temperature can be to obtain the historical initial temperature of the refrigeration space before the refrigeration equipment starts, and to take the average of a plurality of historical initial temperatures as the target historical initial temperature. Alternatively, the historical initial temperature of the refrigeration space before the refrigeration equipment starts can be obtained, and the historical initial temperatures corresponding to different unit periods are weighted and summed to obtain the target historical initial temperature.

[0077] S302, the target power consumption of the refrigeration equipment to bring the refrigeration space from the target historical initial temperature to the space refrigeration temperature is obtained, and the required starting time of the refrigeration equipment in a unit period is determined according to the target power consumption.

[0078] The historical power consumption of the refrigeration equipment to bring the refrigeration space from the target historical initial temperature to the space refrigeration temperature and the corresponding historical starting time of the refrigeration equipment are obtained, and the target power consumption is determined according to the power consumption cost data corresponding to the historical power consumption. The way of determining the target power consumption according to the power consumption cost data corresponding to the historical power consumption is to sort the power consumption cost data corresponding to the historical power consumption, and to select the historical power consumption corresponding to the power consumption cost data in the middle as the target power consumption. The historical starting time of the refrigeration equipment corresponding to the target power consumption is obtained as the required starting time of the refrigeration equipment in a unit period.

[0079] In the embodiment, the required starting time of the refrigeration equipment in a unit period is determined, which can improve the energy utilization rate and reduce the power consumption loss.

[0080] In one embodiment, the unit period includes a power consumption limit period. The flowchart of determining a second target period from the remaining period after elimination is shown in FIG. 2, which includes: Figure 4

[0081] ​​S401, again eliminate the electricity limit period from the period left after elimination, and obtain the electricity cost data of each period left after again eliminating.

[0082] The electricity limit period is a period in which the electricity consumption is required to be reduced.

[0083] S402, sort the electricity cost data of each period left after again eliminating, and determine the second target period in all periods left after again eliminating according to the electricity cost data from low to high.

[0084] In this embodiment, the period corresponding to the low electricity cost data is selected as the second target period, which can reduce the electricity cost.

[0085] In one embodiment, the refrigeration equipment is monitored to avoid the refrigeration space from not reaching the required space refrigeration temperature due to the failure of the refrigeration equipment. The flowchart for controlling the refrigeration equipment to start when the refrigeration equipment fails is shown in Figure 5 , which includes the following steps:

[0086] S501, during the operation of the refrigeration equipment, obtain the operation parameters of the refrigeration equipment and the environmental parameters of the refrigeration space.

[0087] The operation parameters are related parameters generated when the refrigeration equipment is running. The operation parameters include current, voltage, power and electricity consumption. The environmental parameters are related parameters in the refrigeration space where the refrigeration equipment is running. The environmental parameters include temperature, humidity and carbon dioxide content.

[0088] S502, determine whether the operation parameters are greater than the set operation parameter threshold and whether the environmental parameters are greater than the set environmental parameter threshold.

[0089] In some embodiments, it is determined whether the obtained current of the refrigeration equipment is greater than the set current threshold and whether the obtained humidity of the refrigeration space is greater than the set humidity threshold.

[0090] S503, in the case of both being greater, determine that the refrigeration equipment fails.

[0091] When the real-time obtained operation parameters and environmental parameters are greater than the set parameter threshold, the refrigeration equipment is likely to fail. To avoid the refrigeration equipment from being completely damaged, the refrigeration equipment should be controlled to stop running and be repaired.

[0092] S504, control the refrigeration equipment to stop running, eliminate the first target period and the second target period from all periods, and determine a supplementary period from the periods left after elimination, and control the refrigeration equipment to start according to the supplementary period.

[0093] In the embodiment, the way of determining the supplementary time period from the time period left after the elimination can also be that the power consumption cost data of the time period left after the elimination is obtained, the supplementary time period is determined in the time period left after the elimination from low to high according to the power consumption cost data, the power consumption cost is reduced, and the power consumption loss is reduced.

[0094] Based on the power consumption control method of the refrigeration equipment provided in the above embodiments, a refrigeration equipment power consumption control system is provided in the embodiment, and a structural block diagram of the refrigeration equipment power consumption control system is shown in Figure 6 The refrigeration equipment power consumption control system includes a parameter acquisition module, a data transmission module and a control module. The parameter acquisition module is used to acquire the operating parameters of the refrigeration equipment and the environmental parameters of the refrigeration space; the data transmission module is used to receive the operating parameters of the refrigeration equipment and the environmental parameters of the refrigeration space and transmit them to the control module; and the control module is used to process the operating parameters of the refrigeration equipment and the environmental parameters of the refrigeration space to obtain a control instruction for controlling the refrigeration equipment to be turned on, and send the control instruction to the refrigeration equipment controller, so as to control the opening and closing of the refrigeration equipment.

[0095] The parameter acquisition module includes a current transformer, a multifunctional electric meter and a plurality of sensor probes. The current transformer senses the current generated in the refrigeration equipment, the multifunctional electric meter obtains the current value according to the current sensed by the current transformer, and the multifunctional electric meter can also obtain the voltage value, the power value and the power consumption value. The plurality of sensors include a temperature sensor, a humidity sensor and a carbon dioxide concentration sensor. The current transformer is provided to avoid damage to the multifunctional electric meter caused by excessive current generated in the refrigeration equipment.

[0096] The data transmission module includes an intelligent gateway, a PLC module and an Internet of Things platform. The PLC module receives the parameters and transmits them to the intelligent gateway, which transmits the parameters to the Internet of Things platform. The Internet of Things platform transmits the parameters to the control module.

[0097] The process of processing the operation parameters of the refrigeration equipment and the environmental parameters of the refrigeration space in the control module is as follows: obtaining the initial temperature of the refrigeration space and determining the required space refrigeration temperature of the refrigeration space in a unit period, and determining the required starting duration for the refrigeration equipment to make the refrigeration space reach the required space refrigeration temperature. The electricity consumption degree of different time periods in the unit period is determined according to the historical electricity consumption data, and a time period with low electricity consumption degree is selected as a first target time period. In the case where the required starting duration is not greater than the cumulative duration corresponding to the plurality of first target time periods, electricity cost data of each first target time period is obtained. The electricity cost data of different first target time periods is sorted, and the first target time period is removed from all first target time periods according to the electricity cost data from high to low. The refrigeration equipment is controlled to start according to the first target time period remaining after the removal. In the case where the required starting duration is greater than the cumulative duration corresponding to the plurality of first target time periods, all first target time periods are removed from all time periods, and a second target time period is determined from the time periods remaining after the removal. If the unit period contains a power consumption limit period, the power consumption limit period is removed again from the time periods remaining after the removal. Electricity cost data of each time period remaining after the removal is obtained, and the electricity cost data of each time period remaining after the removal is sorted. The second target time period is determined in all time periods remaining after the removal according to the electricity cost data from low to high. The refrigeration equipment is controlled to start according to the first target time period and the second target time period. In the case where the obtained operation parameters of the refrigeration equipment and the environmental parameters of the refrigeration space are all greater than the set parameter threshold, the refrigeration equipment is controlled to stop running, the first target time period and the second target time period are removed from all time periods, and a supplementary time period is determined from the time periods remaining after the removal. The refrigeration equipment is controlled to start according to the supplementary time period.

[0098] The refrigeration equipment electricity control system provided by the embodiment can determine the electricity consumption degree of different time periods by analyzing the historical electricity consumption data of the target region where the refrigeration equipment is located, and then determine a plurality of first target time periods according to the electricity consumption degree of different time periods. In the case where the required starting duration of the refrigeration equipment is greater than the cumulative duration corresponding to the plurality of first target time periods, and in the case where the required starting duration of the refrigeration equipment is not greater than the cumulative duration corresponding to the plurality of first target time periods, two ways of controlling the refrigeration equipment to start are provided, which can ensure that the refrigeration space can reach the required space refrigeration temperature, reduce electricity consumption loss, and improve energy utilization rate.
