It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, a multi-connected unit control method is provided, which can be applied in an application environment as shown in fig. 1 and implemented based on a multi-connected unit control system. The multi-connected machine group control system can be understood as a website deployed in a user computer, and the multi-connected machine group control method can be realized by installing the multi-connected machine group control system in the computer. It is understood that the multi-connected unit control method may also be implemented by other intelligent devices, as long as the skilled person in the art can realize the method. The multi-connected unit control method can be used for controlling multi-connected units, including but not limited to air conditioner multi-connected units and the like. Generally, a multi-connected unit includes a unit, a controller and an information forwarding device, where the information forwarding device includes a router or a switch, the unit includes more than two unit devices, one controller is connected to one or more unit devices, the number of the controllers is also more than two, each controller is used to obtain information of the connected device and send the information to the information forwarding device, and the information forwarding device can implement data transmission between the controller and devices such as an upper computer, and connect multiple controllers to the same local area network, for example, the information from the controller can be forwarded to the upper computer, and an instruction sent by the upper computer can be transmitted to the controller, so as to implement control of the unit devices. Referring to fig. 2, the multi-connected unit control method includes the following steps:
step S200: and acquiring schedule reservation information and target energy consumption of target equipment in the multi-connected unit.
Specifically, the schedule reservation information includes time information, and the time information may be time information, duration information, time period information, or the like. The schedule reservation information may further include target mode information and the like, and the target mode information is an operation mode of a desired multi-connected unit, such as cooling or refrigeration, and may further include a target temperature and the like. The target equipment in the multi-connected unit refers to equipment which needs to be controlled or monitored, generally speaking, the multi-connected unit comprises a plurality of pieces of equipment, and the target equipment can be part or all of the equipment in the multi-connected unit and is determined according to user requirements. The target energy consumption refers to the desired energy consumption, and may be a specific energy consumption value or range of energy consumption values.
The schedule reservation information, the target equipment and the target energy consumption can be set by a user, and the user can set the schedule reservation information, the target equipment and the target energy consumption which can meet the requirements for subsequent use. In this embodiment, a multi-connected unit control method is implemented based on a multi-connected unit control system, for example, an air conditioning unit, a user enters an intelligent reservation interface of the multi-connected unit control system, and sets a schedule according to actual conditions, and the multi-connected unit control system obtains schedule reservation information. For example: when the user 8: 30 on duty, 11:30 off duty, 8:20 air conditioner can be set to start, the mode is set to cool, the temperature is 27 ℃, and 11:20 air conditioner can be set to shut down. Then, the user can enter an energy-saving control function interface of the multi-connected cluster control system and can set the target energy consumption of the target equipment. For example: the power consumption of the air conditioners from room 101 to room 110 is set to be controlled within 500kw × h. Furthermore, a user can set the target energy consumption of the specified equipment in a fixed period, and the multi-connected group control system acquires the target energy consumption of the specified equipment in the fixed period, wherein the fixed period is not unique. For example, the power consumption of the air conditioners from room 101 to room 110 is controlled to be within 500kw · h on monday to friday.
Step S400: and distributing the target energy consumption to a time period corresponding to the schedule reservation information to obtain the target power consumption.
The time slot corresponding to the schedule reservation information may be an entire time slot, or may include two or more sub-time slots. When the time slot corresponding to the schedule reservation information is an overall time slot, the target energy consumption is the target power consumption of the overall time slot. And when the time period corresponding to the schedule appointment information comprises more than two sub-time periods, distributing the target energy consumption to each sub-time period to obtain the target energy consumption in each sub-time period. The distribution mode is not unique, the target energy consumption can be evenly distributed to each sub-time period, different energy consumption can be distributed to each sub-time period according to the use condition, the demand and the like, the target power consumption corresponding to each sub-time period can be the same, partially different and totally different, and the target power consumption can be specifically selected according to the actual situation, as long as the target power consumption can be realized by a person skilled in the art.
Step S600: and obtaining the simulated power consumption in the time period corresponding to the schedule appointment information according to the preset equipment parameters of the target equipment.
The preset device parameters are parameters which are configured or set in advance, and the preset device parameters are parameters which influence the power consumption. In this embodiment, the preset device parameters may include capacities of the indoor and outdoor units of the multi-connected unit, for example, capacities of the indoor and outdoor air conditioning devices, and may further include a duration, a mode, a temperature, and the like of a preset setting. Taking a multi-connected unit as an air conditioning unit as an example, parameters such as the refrigerating capacity of the air conditioner, the capacity of an outdoor unit, the power of a compressor, the set operation time, the operation mode, the set temperature and the like are obtained, and then the simulated energy consumption is calculated through thermodynamics, a refrigeration formula and the like. The simulated energy consumption may be used as a simulated power consumption.
Furthermore, the way of obtaining the simulated power consumption is different according to different time periods corresponding to the schedule reservation information. After the simulated energy consumption calculated according to the preset equipment parameters is obtained, the simulated energy consumption can be distributed to the time period corresponding to the schedule appointment information, and the simulated power consumption is obtained. The time slot corresponding to the schedule reservation information may be an entire time slot, or may include two or more sub-time slots. When the time period corresponding to the schedule reservation information is an integral time period, the simulated energy consumption is the simulated power consumption of the integral time period. And when the time period corresponding to the schedule appointment information comprises more than two sub-time periods, distributing the simulated energy consumption to each sub-time period to obtain the simulated energy consumption in each sub-time period. The distribution mode is not unique, the simulated energy consumption can be evenly distributed to each sub-time period, different energy consumption can be distributed to each sub-time period according to the use condition, the demand and the like, the simulated energy consumption corresponding to each sub-time period can be the same, partially different and totally different, and the simulated energy consumption can be specifically selected according to the actual situation, as long as the simulated energy consumption can be realized by the technical personnel in the field.
Step S800: when the target power consumption is larger than the simulated power consumption, more than two types of adjustable parameters are sent to the information prompting module for prompting, and after a user confirmation instruction is received, the adjustable parameters corresponding to the user confirmation instruction are adjusted to reduce the target power consumption.
In this embodiment, the target power consumption amount and the simulated power consumption amount may be both power consumption amounts corresponding to the time period corresponding to the schedule reservation information as a whole time period. When the target power consumption is larger than the simulated power consumption, the energy consumption required by the user is considered to exceed the energy consumption generated by the multi-connected unit under the working of the standard state, at the moment, more than two types of adjustable parameters are sent to the information prompting module for prompting, and various energy-saving schemes are provided for the user to select. The type of the information prompting module is not unique, and the corresponding prompting modes are different. In this embodiment, taking the information prompting module as an example of the display interface, the energy saving scheme including the adjustable parameters can be displayed in the form of a chart or characters, and the display content is accurate and intuitive. It is understood that in other embodiments, the information prompting module may be of other types, such as a voice prompting module with convenient prompting, and may be selected according to actual requirements.
After receiving the prompt message, the user selects an energy-saving scheme according to factors such as self requirements and the like, and sends a confirmation instruction. And after receiving the user confirmation instruction, the multi-connected machine group control system adjusts the adjustable parameters corresponding to the user confirmation instruction so as to reduce the target power consumption. In order to improve the energy-saving effect, the adjustable parameters can be adjusted for multiple times or long time by prompting for multiple times or for long time until the adjusted target power consumption is less than or equal to the simulated power consumption, so that the energy consumption of the unit is reduced, and the energy consumption waste is reduced. The adjustable parameters are parameters capable of influencing the energy consumption of the multi-connected unit, the types of the adjustable parameters are more than two, at least two energy-saving schemes can be provided for users, and the energy-saving effect can be achieved by adjusting any one of the parameters.
In this embodiment, taking the adjustable parameters including temperature, humidity, wind speed and air outlet direction as an example, when the target power consumption is greater than the simulated power consumption, the system customizes different energy-saving control schemes from multiple dimensions such as temperature, humidity, wind speed and air outlet direction. For example, when an air conditioner is used in an unsealed space and the difference between the set temperature and the outdoor temperature is large, the indoor environment temperature cannot reach the set temperature of the air conditioner, the lowest temperature which can be reached by the current environment can be found by the temperature, the humidity, the wind speed, the wind outlet direction and the like, and the set temperature is changed to reduce the running frequency of the compressor, so that the energy-saving effect is achieved. The multiple energy-saving schemes can meet different user use scenes, for example, the user needs to keep the temperature unchanged and can accept reduction of the environmental humidity, or the user needs to keep the environmental humidity and can reduce energy consumption by adjusting the set temperature, the set wind speed and the like, and the user can select the energy-saving schemes according to actual requirements. After the user selects the energy-saving scheme, the multi-connected machine group control system receives the user confirmation instruction, and the adjustable parameters in the energy-saving scheme are adjusted according to the energy-saving scheme corresponding to the user confirmation instruction, so that the target power consumption is reduced, and the purpose that the simulated power consumption meets the target power consumption is achieved.
In one embodiment, referring to fig. 3, after step S600, the multi-split air conditioning unit control method further includes step S710 and step S720.
Step S710: when the target power consumption is less than or equal to the simulated power consumption, the actual power consumption of the target device is obtained.
When the target power consumption is less than or equal to the simulated power consumption, the energy consumption of the multi-connected unit generated under the working of the standard state is considered to meet the energy consumption required by the user, the actual power consumption of the target equipment is obtained at the moment, and the actual power consumption of the equipment is monitored to achieve a better energy-saving effect. Specifically, the actual power consumption may be obtained by obtaining operating parameters of the target device, for example, by using the operating power, the operating duration, the operating mode, the set temperature, and the like of the compressor, and then calculating the actual power consumption of the target device according to the thermodynamics and the refrigeration formula, and the like.
Step S720: when the actual power consumption is larger than the target power consumption, more than two types of adjustable parameters are sent to the information prompting module for prompting, and after a user confirmation instruction is received, the adjustable parameters corresponding to the user confirmation instruction are adjusted, so that the actual power consumption is reduced.
When the actual power consumption is larger than the target power consumption, the current energy consumption of the target equipment is considered to be higher, and the energy is not saved during working. At the moment, more than two types of adjustable parameters are sent to the information prompting module for prompting, and various energy-saving schemes are provided for the user to select. After receiving the prompt message, the user selects an energy-saving scheme according to factors such as self requirements and the like, and sends a confirmation instruction. And after receiving the user confirmation instruction, the multi-connected machine group control system adjusts the adjustable parameters corresponding to the user confirmation instruction so as to reduce the actual power consumption. In order to improve the energy-saving effect, the prompt can be performed for multiple times or a long time, the adjustable parameters are adjusted for multiple times until the actual power consumption is less than or equal to the target power consumption after adjustment, so that the energy consumption of the unit is reduced, and the energy consumption waste is reduced. The adjustable parameters are parameters capable of influencing the energy consumption of the multi-connected unit, the types of the adjustable parameters are more than two, at least two energy-saving schemes can be provided for users, and the energy-saving effect can be achieved by adjusting any one of the parameters.
In an embodiment, referring to fig. 3, after step S710, the multi-connected unit control method further includes step S730.
Step S730: and sending the actual power consumption and the target power consumption to an information prompting module for prompting.
After the actual power consumption of target equipment is obtained, the actual power consumption and the target power consumption are sent to the information prompting module for prompting, so that a user can know the actual power consumption and the target power consumption in time, and when the actual power consumption or the target power consumption needs to be adjusted, the adjustment can be performed in time, and the use is convenient. Further, when the actual power consumption is less than or equal to the target power consumption, the actual power consumption and the target power consumption can be sent to the information prompting module for prompting. Because when actual power consumption is greater than target power consumption, can adjust actual power consumption, can temporarily not indicate or few actual power consumption of suggestion this moment to alleviate the work load of information suggestion module, simplify the suggestion content.
The type of the information prompting module is not unique, and the corresponding prompting modes are different. In this embodiment, taking the information prompting module as an example of the display interface, the energy saving scheme including the adjustable parameters can be displayed in the form of a chart or characters, and the display content is accurate and intuitive.

It is understood that in other embodiments, the information prompt module may be of other types, such as a voice prompt module, and may be selected according to actual requirements.
In one embodiment, referring to fig. 3, after step S600, the multi-connected unit control method further includes step S810.

When the target power consumption is larger than the simulated power consumption, the target power consumption can be adjusted, and at the moment, the target power consumption can be temporarily not prompted or less prompted, so that the workload of the information prompting module is reduced, and the prompting content is simplified.
The type of the information prompting module is not unique, and the corresponding prompting modes are different. In this embodiment, taking the information prompting module as an example of the display interface, the energy saving scheme including the adjustable parameters can be displayed in the form of a chart or characters, and the display content is accurate and intuitive.

Specifically, when the corresponding actual power consumption amount in the same sub-period is smaller than the target power consumption amount, it is considered that the power consumption amount actually consumed in the current sub-period is already a relatively energy-saving scheme. At the moment, the difference value between the target power consumption and the actual power consumption corresponding to the sub-time period is distributed to the target power consumption corresponding to other sub-time periods, so that the multi-connected unit in other sub-time periods is guaranteed to have sufficient target power consumption, and the working performance of the multi-connected unit is improved. The difference value can be a difference value, or the difference value minus an allowable floating value and the like, so that a certain margin is reserved for the actual power consumption, the condition of working fluctuation of the multi-connected unit can be better considered, and the working effect of the multi-connected unit is guaranteed. Further, when the difference value is allocated to the corresponding target power consumption amount in the other sub-time period, there are various allocation manners. For example, the difference value may be averagely allocated to the corresponding target power consumption in other sub-time periods, or different target power consumption may be added to each of the other sub-time periods according to the use situation, the demand, and the like, and the target power consumption added in each sub-time period may be the same, partially different, or completely different, and may be specifically selected according to the actual situation, as long as the implementation is considered by those skilled in the art.
In an embodiment, referring to fig. 4, before step S200, the multi-split air conditioning unit control method further includes step S100.
Step S100: and in the multi-connected unit, acquiring the target equipment with the established connection.
Specifically, after a user installs the software of the multi-connected machine group control system, the software of the multi-connected machine group control system is connected with an intelligent controller in the multi-connected machine group, target equipment which is connected with the multi-connected machine group is obtained in the multi-connected machine group, the multi-connected machine equipment is searched on a software interface, and the user can monitor the equipment state at the moment, so that subsequent operation is facilitated.
In one embodiment, the adjustable parameter includes at least one of temperature, humidity, wind speed, and vent direction.
Specifically, the adjustable parameters may include one, two, three, or all of temperature, humidity, wind speed, and air outlet direction, and the adjustable parameters may also include other types of parameters, and may be set according to actual requirements. In this embodiment, taking the adjustable parameters including temperature, humidity, wind speed and air outlet direction as an example, when the target power consumption is greater than the simulated power consumption, the system customizes different energy-saving control schemes from multiple dimensions such as temperature, humidity, wind speed and air outlet direction. For example, when an air conditioner is used in an unsealed space and the difference between the set temperature and the outdoor temperature is large, and the indoor environment temperature cannot reach the set temperature of the air conditioner, the lowest temperature which can be reached by the current environment can be found from the temperature, the humidity, the wind speed, the wind outlet direction and the like, and the set temperature is changed to reduce the running frequency of the compressor so as to achieve the effect of energy conservation.
For a better understanding of the above embodiments, the following detailed description is given in conjunction with a specific embodiment. In an embodiment, a multi-connected unit control method is implemented based on a multi-connected unit control system, and a multi-connected unit is an air conditioning unit, for example, please refer to fig. 5, where the multi-connected unit control method includes the following steps:
the first step is as follows: after a user installs the software of the multi-connected unit control system, the user is connected with the intelligent controller in the multi-connected unit to search the multi-connected equipment on a software interface, and at the moment, the user can monitor the equipment state. The multi-connected cluster control system can be understood as a website deployed in a user computer and can be used only when a user is installed in the computer. The multi-connected machine group control system is displayed by a user interface, and can be accessed into a plurality of controllers through a router to realize the monitoring of the machine group state.
The second step is that: and the user enters an intelligent appointment interface and sets schedule appointment according to actual conditions. (for example: 8: 30 on duty, 11:30 off duty, 8:20 air conditioner on, mode refrigeration, 27 degree temperature, 11:20 air conditioner off.)
The third step: and the user enters an energy-saving control function interface and can set the target energy consumption of the specified equipment in a fixed period. (for example: Monday to Friday, power consumption of air conditioners from room 101 to room 110 is controlled within 500kw h.)
The fourth step: the energy-saving control function distributes energy consumption to each schedule appointment time period according to schedule appointment setting parameters of a user, and particularly can distribute the energy consumption evenly according to target energy consumption and set air conditioning equipment. And acquiring the electricity consumption condition of the equipment every hour, if the electricity consumption condition is remained, equally dividing the remained electricity into other time periods, and if the electricity consumption condition is excessive, subtracting the excess part from the total energy consumption target and equally dividing the electricity again.
The fifth step: the system simulates the power consumption of each reservation according to the parameters of the air conditioning equipment (such as the capacity of the indoor and outdoor air conditioning equipment but not limited to capacity) and the parameters of the duration, the mode, the temperature and the like of the reservation setting. Specifically, the air conditioner refrigerating capacity, the outdoor unit capacity, the compressor power, the set operation time, the operation mode and the set temperature are obtained, and the power consumption is calculated through thermodynamics, a refrigeration formula and the like.
And a sixth step: the power consumption amount allocated to each reservation based on the target power consumption (simply referred to as allocated power consumption amount, corresponding to the target power consumption in the foregoing) and the power consumption amount simulated based on the actual parameter (simply referred to as simulated power consumption amount) are compared.
The seventh step: if the distributed power consumption can not meet the simulated power consumption, the system customizes different energy-saving control schemes from multiple dimensions such as temperature, humidity, wind speed, air outlet direction and the like. For example, when an air conditioner is used in an airtight space and the difference between the set temperature and the outdoor temperature is large, the indoor ambient temperature cannot reach the set temperature of the air conditioner, the lowest temperature which can be reached by the current environment can be found by the temperature, the humidity, the wind speed, the wind outlet direction and the like, and the set temperature is changed to reduce the operating frequency of the compressor, so that the energy-saving effect is achieved.
Eighth step: the multiple energy-saving schemes can meet different user use scenes (for example, a user needs to keep the temperature unchanged and can accept reduction of the environmental humidity, or the user needs to keep the environmental humidity and can reduce energy consumption by adjusting the set temperature, the set wind speed and the like), and the user can select the energy-saving schemes according to actual requirements.
The ninth step: the system adjusts the subscription setting parameters according to an energy saving scheme to achieve the goal of meeting the allocated power consumption.
The tenth step: if the distributed power consumption can meet the simulated power consumption, the system generates an energy consumption distribution graph and monitors the power consumption condition of the equipment in real time (comparing the actual energy consumption with the distributed energy consumption). The energy consumption distribution map can visually provide actual power consumption conditions for a user, and is used for analyzing reasonable conditions of schedule reservation and energy-saving control, and relevant parameters can be changed accordingly, so that parameter setting is more reasonable.
The eleventh step: if the actual power consumption exceeds the distributed power consumption during the actual use, the seventh step is executed.
The energy-saving control method and the energy-saving control system have the advantages that the schedule setting and the energy consumption target in a fixed period of a user are combined, a multi-dimensional energy-saving control scheme is set for the user from the temperature, the humidity, the wind speed and the like, the user can select the energy-saving control scheme according to actual conditions, the operation duration and the operation parameters of the unit are set according to parameters of an indoor unit and an outdoor unit and the schedule, an energy consumption distribution map is generated, and the energy consumption of the unit can be accurately controlled in real time. The energy-saving aim of the air conditioner is achieved by actively and regularly adjusting the set states of the air conditioning equipment such as temperature, humidity, wind speed, air outlet direction and the like. The display interface of the multi-connected machine group control system can see the predicted power consumption of each section of schedule and the distribution situation of the energy consumption of the machine group, and the target power consumption in a fixed period can be set in the energy-saving control function. The power consumption of the unit is controlled within the target energy consumption by observing the power consumption condition of the air conditioner and the running state of the air conditioner. The method comprises the steps of changing parameters set in original schedule appointment in the operation process of a unit, automatically adjusting the operation parameters of the air conditioner by a system for controlling energy consumption after the unit operates for a period of time (for example, the original air conditioner 1 is set to start at 9 to 11 am for refrigeration, the temperature is 27 ℃, the air speed is automatic, manually adjusting the temperature to 16 ℃ when the temperature is 09: 10, the air speed is strong wind, and the system automatically adjusts the set state parameters of the air conditioner for controlling the energy consumption of the air conditioner not to exceed the target energy consumption after a room where the air conditioner is located and doors and windows are opened to operate for a period of time).
The multi-connected unit control method comprises the steps of firstly obtaining schedule reservation information and target energy consumption of target equipment in a multi-connected unit, then distributing the target energy consumption to a time period corresponding to the schedule reservation information to obtain target power consumption, then obtaining simulated power consumption in the time period corresponding to the schedule reservation information according to preset equipment parameters of the target equipment, sending more than two types of adjustable parameters to an information prompt module for prompting when the target power consumption is larger than the simulated power consumption, and adjusting the adjustable parameters corresponding to a user confirmation instruction after receiving the user confirmation instruction to reduce the target power consumption. According to the scheme, the target power consumption is obtained according to schedule appointment and expected target energy consumption, then the simulation power consumption associated with the schedule is obtained by combining preset equipment parameters of the target equipment, when the target power consumption is larger than the simulation power consumption, more than two types of adjustable parameters are sent to the information prompt module for prompting, a multi-dimensional energy-saving control scheme is formulated for a user, the user can select the energy-saving control scheme according to actual conditions, after a user confirmation instruction is received, the adjustable parameters corresponding to the user confirmation instruction are adjusted, the target power consumption is reduced, different energy-saving schemes can be provided for different target equipment on the premise that user requirements are met, the energy-saving effect is good, and the working performance of the multi-connected unit is improved.
