The control method provided by the application is mainly applied to a parking air conditioner, wherein the control method provided by the application can be applied to a server and also can be applied to a system formed by mutually matching the server and terminal equipment. Accordingly, the respective parts involved in the control method, for example, the respective units, sub-units, modules, and sub-modules, may be all disposed in the server, or may be disposed in the server and the terminal device, respectively.
Further, the server may be hardware or software. When the server is hardware, the server may be implemented as a distributed server cluster formed by a plurality of servers, or may be implemented as a single server. When the server is software, it may be implemented as a plurality of software or software modules, for example, software or software modules for providing a distributed server, or may be implemented as a single software or software module, which is not specifically limited herein. In some possible implementations, the control method of the embodiments of the present application may be implemented by a processor invoking computer readable instructions stored in a memory.
The control method provided by the application is mainly applied to control refrigerating equipment based on power supply of a storage battery and the like of the parking air conditioner, and the operating frequency of the compressor of the air conditioner is adjusted in real time based on the operating voltage and the operating effect of the parking air conditioner, namely the temperature change of the air conditioner operating environment, by periodically identifying the operating voltage of the compressor battery of the parking air conditioner, so that the operating frequency of the compressor is adjusted according to the voltage of the storage battery.
The current control to the parking air conditioner mainly adjusts the frequency of the compressor to a fixed gear through the manual operation of a driver, and the parking air conditioner cannot adopt full-frequency-band variable frequency like a household variable frequency air conditioner. And when the voltage of the storage battery is lower, the high frequency of the operation of the compressor can lead to the rapid decrease of the electric quantity of the battery, and the feeding phenomenon occurs. Based on the above, the application provides a control method of a parking air conditioner, and the following describes the technical scheme adopted by the application in detail.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic flow chart of a first embodiment of a control method provided by the present application, and fig. 2 is a schematic flow chart of an application control method in a parking air conditioner provided by the present application.
Step 11: and respectively acquiring voltage information of the compressor and in-vehicle environment temperature information.
Specifically, the voltage information of the compressor includes: the current voltage and the shutdown voltage of the compressor, and the in-vehicle environment temperature information comprises: sampling temperature and target temperature.
Specifically, after the parking air conditioner receives a starting instruction sent by a user, the compressor is started, and the current running voltage Us of the compressor and the shutdown voltage Ut of the parking air conditioner for protecting the battery are obtained. The shutdown voltage may be determined according to the capacity of the storage battery used in the parking air conditioner, which is not limited herein.
Specifically, after the parking air conditioner collects the current running voltage Us and the shutdown voltage Ut of the compressor, the sampling temperature Ta of the working environment of the current parking air conditioner and the target temperature Ts set by the user are also obtained.
Step 12: the operating frequency of the compressor is calculated based on the voltage information and the in-vehicle environment temperature information.
Alternatively, the present embodiment may implement step 12 by a method as shown in fig. 3, and fig. 3 is a schematic flow chart of an embodiment of step 12 in the embodiment of fig. 1 in the control method provided by the present application. Specifically, the method of the present embodiment includes steps 31 to 32.
Step 31: and obtaining a voltage difference value between the current voltage and the shutdown voltage.
Specifically, the voltage difference U is the difference between the voltage Us at which the compressor is currently operating and the shutdown voltage Ut of the parking air conditioner itself for protecting the battery, i.e., us-Ut.
Step 32: a first average value of the difference between the sampling temperature and the target temperature in the current time period and a second average value of the difference between the sampling temperature and the target temperature in the previous time period are obtained.
Specifically, the parking air conditioner acquires the current in-vehicle temperature Tb after the compressor operation time interval N. When the operation mode of the parking air conditioner is refrigeration, the first average value is the average value of the difference value between the current temperature in the vehicle and the target temperature Ts set by the user, namely Tb-Ts. The second average value is the average value of the difference between the temperature Ta in the vehicle acquired in the previous time period and the target temperature set by the user, namely Ta-Ts. When the operation mode of the parking air conditioner is heating, the first average value T1 is Ts-Tb, and the second average value T2 is Ts-Ta.
Step 33: the operating frequency of the compressor is calculated based on the voltage difference and the first and second averages.
In an embodiment of the present application, the parking air conditioner may calculate the operating frequency of the compressor by converting the voltage difference and the first and second average values into the voltage coefficient, the temperature difference coefficient, and the temperature difference change rate coefficient.
Alternatively, the method shown in fig. 4 may be used to implement step 33 in this embodiment, and fig. 4 is a schematic flow chart of an embodiment of step 33 in the embodiment of fig. 3 in the control method provided by the present application, where the method in this embodiment specifically includes steps 41 to 43.
Step 41: the voltage difference is converted to a voltage coefficient and the first average is converted to a temperature difference coefficient.
In an embodiment of the present application, the parking air conditioner may perform coefficient conversion on the voltage difference and the first average value through the conversion diagrams of fig. 5 and 6. Referring to fig. 5 and fig. 6, fig. 5 is a schematic diagram illustrating an embodiment of converting a voltage difference into a voltage coefficient in the control method according to the present application, and fig. 6 is a schematic diagram illustrating an embodiment of converting a first average value into a temperature difference coefficient in the control method according to the present application.
Specifically, the parking air conditioner may convert the voltage difference value into a voltage coefficient according to the correspondence relationship between the voltage difference value and the voltage coefficient in fig. 5. As shown in fig. 5, the voltage coefficient a has a value in the range of 0,1, and can be set according to the capacity of the battery in the vehicle. When the voltage difference U is between 0 and 1, the voltage coefficient A is 0, and the voltage difference U is between 1 and 2, the voltage coefficient is 0.2. Similarly, when the voltage difference is equal to or greater than 5, the voltage coefficient A is 1.
Specifically, the parking air conditioner may convert the first average value into the temperature difference coefficient according to the correspondence relationship between the first average value and the temperature difference coefficient in fig. 6. As shown in fig. 6, the range of the temperature difference coefficient B may be set according to the size of the cab space different from the refrigerating system. When the temperature difference T is between-0.5 and 0.5, the temperature coefficient B takes a value of 0; when the temperature difference T is greater than 0.5-1, the temperature coefficient B takes a value of 1, and the like, and when the temperature difference T is greater than 2, the temperature coefficient B takes a value of 4.
Step 42: and calculating a temperature difference value between the first average value and the second average value, and converting the temperature difference value into a temperature difference change rate coefficient.
Specifically, the temperature difference, i.e., the temperature difference change rate, tc, is derived from the difference between the temperature difference, fatn, in the current period N and the temperature difference, fatt (N-1), in the previous period N-1. After calculating the temperature difference fattc between the first average value fatt 1 and the second average value fattc, the parking air conditioner also converts the temperature difference value into a temperature difference change rate coefficient. Referring to fig. 7, fig. 7 is a schematic diagram illustrating an embodiment of converting a temperature difference into a temperature difference change rate coefficient in the control method according to the present application.
Specifically, the parking air conditioner may convert the temperature difference value into the temperature difference change rate coefficient according to the correspondence relationship between the temperature difference value and the temperature difference change rate coefficient in fig. 7. As shown in fig. 7, the range of the temperature difference change rate coefficient may be set according to the size of the cab space different from the refrigerating system. When the temperature difference is between-0.5 and 0.5, the temperature difference change rate coefficient C takes a value of 0, and when the temperature difference is between 0.5 and 1, the temperature difference change rate coefficient C takes a value of 0.5. When the Tc of the temperature difference value is larger than 2, the coefficient C of the temperature difference change rate takes a value of 2; when the temperature difference is equal to-0.5 to-1, the temperature difference change rate coefficient C takes the value of 1, and when the temperature difference is smaller than-2, the temperature difference change rate coefficient C takes the value of 4.
Step 43: and obtaining the operating frequency of the compressor according to the voltage coefficient, the temperature difference coefficient and the temperature difference change rate coefficient.
Alternatively, the present embodiment may implement step S43 by using a method as shown in fig. 8, where fig. 8 is a schematic flow chart of an embodiment of the specific implementation of step 43 in the embodiment of fig. 4 in the control method provided by the present application. In this embodiment, the parking air conditioner may further perform validity judgment on the voltage coefficient, so as to obtain a more accurate operating frequency to control the compressor.
Step 81: it is determined whether the voltage coefficient is valid.
Specifically, the parking air conditioner calculates a first product value of a first average value and a temperature difference coefficient and a second product value of a temperature difference change rate coefficient and a temperature difference value; and calculating the sum of the first product value and the second product value to obtain a judgment coefficient. I.e. the determination factor f= the father t+b+father Tc. And the parking air conditioner responds to the fact that the judging coefficient is larger than zero, namely, the father T+B+father Tc is larger than or equal to 0, the voltage coefficient A is determined to be effective, and if the judging coefficient is larger than or equal to zero, namely, the father T+B+father Tc is smaller than or equal to 0, the voltage coefficient A is determined to be ineffective. If the voltage coefficient a is valid, the process proceeds to step 82, and otherwise proceeds to step 83.
Step 82: and obtaining the compensation frequency based on the voltage coefficient, the temperature difference change rate coefficient and the temperature difference value and the first average value.
Specifically, the parking air conditioner calculates a first product value of a first mean value and a temperature difference coefficient and a second product value of a temperature difference change rate coefficient and a temperature difference value, calculates a sum of the first product value and the second product value after the first product value and the second product value are obtained, and multiplies the sum by a voltage coefficient to obtain a compensation frequency.
Step 83: the compensation frequency is obtained based on the temperature difference coefficient, the temperature difference change rate coefficient, the temperature difference value and the first average value.
Specifically, if the voltage coefficient is invalid, the parking air conditioner responds to the invalid voltage coefficient, and the compensation frequency is obtained based on the temperature difference coefficient, the temperature difference change rate coefficient, the temperature difference value and the first average value.
The parking air conditioner calculates a first product value of a first average value and a temperature difference coefficient and a second product value of a temperature difference change rate coefficient and a temperature difference value; and calculating the sum of the first product value and the second product value to obtain the compensation frequency.
Specifically, when the voltage coefficient is valid, the compensation frequency f= (+tjb+tc+c) a, and when the voltage coefficient is invalid, the compensation frequency f= tjb+tc+c.
Step 84: the sum of the current operating frequency and the compensation frequency of the compressor is determined as the operating frequency of the compressor.
Specifically, after the parking air conditioner determines that the sum of the current operating frequency and the compensation frequency of the compressor is the operating frequency of the compressor, the air conditioner compressor is also controlled to operate at the operating frequency.
Step 13: the compressor is controlled to operate at an operating frequency.
Alternatively, the parking air conditioner may periodically acquire the battery voltage of the air conditioner compressor at time intervals N, thereby realizing periodic adjustment of the operating frequency of the air conditioner compressor based on the battery voltage. The parking air conditioner in the control method according to the present application may be any refrigerating device powered by a storage battery, such as a car air conditioner, an electric air conditioner of an engineering car, etc., which is not limited herein.
The control method provided by the present application is described in the following in a complete embodiment. A parking air conditioner is arranged in a truck, when the parking air conditioner starts to operate, the current temperature in the truck is 30 ℃, and the operating voltage of the compressor is 25V. The driver turns on the air conditioner and sets the target temperature in the cooling mode to 24 degrees. The protection voltage set by the corresponding battery software of the compressor is 21.5V, and the current running frequency of the compressor is 50Hz. The temperature in the vehicle after one period N has elapsed is 29 degrees.
Calculating the voltage difference U=25-21.5=3.5V, which is 3-4, and taking a voltage coefficient A of 0.6 according to the corresponding relation in FIG. 4; calculating a first average value T1=29-24=5 and a second average value T2=30-24=6 corresponding to the initial temperature after one period N to obtain a first average value T1= 5>2, wherein according to the corresponding relation in fig. 5, T= T1=5, and the temperature difference coefficient B is 4; the temperature difference tc= fatter T1 fatter T2=5-6= -1 is obtained, and the temperature difference change rate coefficient C takes a value of 2 according to the corresponding relation in fig. 6.
Calculating the judgment coefficient f= T1 b+ (+t1- +t2) c= 5*4+ (-1) 2=18, and if F is greater than 0, the voltage coefficient a is valid, and the compensation frequency=fa=18×0.6=10.8 is rounded to 11. Compressor operating frequency=current frequency+offset frequency=50+11=61, so after one period N, the compressor is operated at 61Hz.
