With reference to fig. 1, an embodiment of the present disclosure provides a method for group control of air conditioners between trains, including:
s101, under the condition that a plurality of inter-train air conditioners are networked, a control end determines a group control mode of a networking unit according to an application scene.
And S102, controlling the air conditioners among the columns to execute a control strategy matched with the group control mode by the control end according to the current operating parameters and the target operating parameters.
Here, the control end refers to a control center that connects all air conditioners in the unit through a network and devices. Under different application scenes, the group control modes of the networking units are different. The group control mode is a mode of group control. As an example, the networking units are located in the same machine room, and the machine room is divided into different areas; the control requirements for each zone may be the same or different. The scene belongs to a main and standby scene, in the scene, the group control mode is that the air conditioners between each row operate independently, and the air conditioners between each row have the functions of duty cycle and backup. As another example, the networking unit is applied to a scenario where the thermal load is not uniform. The heat loads of all the areas are different in the scene, so that the air conditioners among the columns in the unit operate in different modes. If the area with low heat load, the corresponding inter-row air conditioner executes a heating mode; in a region with a high heat load, the corresponding inter-row air conditioners perform a cooling mode, which may cause competition among the inter-row air conditioners and waste of resources. Under the scene, the group control mode controls the air conditioners among the rows to avoid competition.
And then, based on the group control mode, determining and executing a control strategy matched with the group control mode by combining the current operating parameters and the target operating parameters of the air conditioners among the columns. As an example, in the foregoing active/standby scenario, the control strategy of the inter-train air conditioners is determined based on the current operating parameters and the target operating parameters. And if the current operating parameters and the target operating parameters indicate that the demand is refrigeration, the control strategy of the inter-row control is refrigeration control, and the inter-row air conditioner is controlled to execute refrigeration. As another example, in the foregoing scenario where the heat load is not uniform, in order to avoid competition among the inter-train air conditioners, a uniform control strategy needs to be determined, for example, the inter-train air conditioners in the unit all execute a heating mode. The cooling mode is prohibited from being performed by one or some of the inter-train air conditioners.
By adopting the method for the group control of the air conditioners among the trains provided by the embodiment of the disclosure, a plurality of air conditioners among the trains are networked to form a unit of a system; and different application scenes are combined, and the unit adopts different group control modes. And controlling the air conditioners among the columns in the unit to execute corresponding control strategies. Therefore, the air conditioners among the rows of the unit can be controlled in a unified mode, and the automatic control of the air conditioners among the rows of the unit can be achieved. Therefore, the control strategy of the air conditioners among the rows in the unit can be matched with the application scene, and better control is realized; thereby achieving better energy-saving effect.
Optionally, in step S101, the control end determines, according to the application scenario, a group control mode of the networking unit, where the group control mode includes:
and under the condition that the application scene is the main and standby scene, the control end determines that the group control mode of the networking unit is the common mode.
And under the condition that the application scene is a scene with uneven heat load, the control end determines that the group control mode of the networking unit is a competition prevention mode.
And under the condition that the application scene is a scene with uniform heat load, the control end determines that the group control mode of the networking unit is a stacked function mode.
In the embodiment of the disclosure, the application scenarios are mainly divided into a main/standby scenario, a scenario with uneven thermal load, and a scenario with even thermal load. Each scene corresponds to a different group control mode. The common mode refers to that inter-row air conditioners in the networking unit run independently. Specifically, each inter-row air conditioner determines a control mode according to an indoor environment parameter detected by itself. Thus, the area where each inter-row air conditioner is located is different, and the area environment is different. Therefore, the control modes of the air conditioners between the columns may be the same or different. Even competitive operation exists, wherein the competitive operation means that the control mode of some inter-row air conditioners is refrigeration, and the control mode of some inter-row air conditioners is heating.
The anti-competition mode means that the control modes of the air conditioners between the columns are consistent, or the air conditioners between the columns are prohibited from executing a certain control mode. For example, the environment of a certain location indicates that the whole environment needs to be cooled, but the ambient temperature of a certain area is relatively low. In this case, if the group control mode is the normal mode, the inter-train air conditioner in the area where the ambient temperature is relatively low performs heating control, and the other inter-train air conditioners perform cooling control. Thus, competition occurs between the inter-row air conditioners, and in order to avoid the competition, the control end issues a control command to prohibit the inter-row air conditioners from executing heating control. In addition, after the inter-train air conditioners perform a predetermined control mode in the anti-competition mode, the operation parameters are controlled based on the data detected by the inter-train air conditioners.
The laminated function mode means that the control modes of the air conditioners in all the rows are consistent, and the control requirements of the air conditioners in most rows are consistent. As an example, the environment of a site indicates that the overall environment requires cooling, and the amount of cooling required for the site is determined. The refrigeration demand is distributed according to a certain distribution principle, such as an average principle, or according to the maximum refrigeration capacity of the air conditioners between the trains. In addition, the distribution according to a certain distribution principle cannot ensure absolute average, so that the refrigerating demand of one inter-row air conditioner is in and out of other inter-row air conditioners.
With reference to fig. 2, another method for group control of air conditioners between trains is provided in an embodiment of the present disclosure, which includes:
s201, under the condition that a plurality of inter-train air conditioners are networked, a control end determines a group control mode of a networking unit according to an application scene.
S202, under the condition that the group control mode is a competition prevention mode or a stacking function mode, a control end selects any one inter-row air conditioner in the networking unit as a host machine, and other inter-row air conditioners are used as slave machines; determining the addresses of the host and the slave; wherein, the host computer is stored with target operation parameters.
And S203, the control end controls the air conditioners among the columns to execute a control strategy matched with the group control mode according to the current operating parameters and the target operating parameters.
In the embodiment of the disclosure, 32 inter-row air-conditioning networking can be supported maximally. Any inter-train air conditioner can be used as a master machine, but only one master machine can be arranged in the whole networking unit, and the rest of the inter-train air conditioners are all slave machines. The host computer and the slave computer are connected and communicated in a 485 bus mode. So that the master machine sends the control command to each slave machine. And when the group control mode of the networking unit is a competition prevention mode or a stacking function mode, the control end uniformly controls and manages the air conditioners among the columns in the networking unit. In this case, the master in the networking unit is responsible for receiving the control command and issuing the control command to each slave. The addresses of the master and the slave are determined for control. In addition, in the two group control modes, the target operation parameters are stored in the master machine, and the master machine shares the target operation parameters with the slave machines.
Optionally, the addresses of the air conditioners between the columns in the networking unit are continuous addresses.
Here, in order to ensure the control normalization and convenience, and simultaneously, in order to expand more inter-column air conditioners subsequently. And continuously coding the networked inter-column air conditioner addresses. Especially in the laminated function mode, the host can issue instructions to each unit according to the unit address coding sequence; the instruction can be prevented from being missed or repeatedly issued. As an example, 7 inter-train air conditioners are networked, and when the master address is 1, the remaining slave addresses are 2, 3, 4, 5, 6, and 7 in this order. Wherein the sequencing order of the slaves is randomly determined.
With reference to fig. 3, another method for group control of air conditioners between trains is provided in an embodiment of the present disclosure, which includes:
s301, under the condition that a plurality of inter-train air conditioners are networked, the control end determines a group control mode of a networking unit according to an application scene.
S302, under the condition that the group control mode is the anti-competition mode, the control end selects any one inter-row air conditioner in the networking unit as a host machine, and other inter-row air conditioners are used as slave machines; determining the addresses of the host and the slave; wherein, the host computer is stored with target operation parameters.
And S331, the control end determines a target operation mode of the networking unit according to the current operation parameters and the target operation parameters of all inter-row air conditioners in the networking unit.
And S332, judging whether the target operation mode is feasible or not by the control end according to the current operation parameters and the target operation parameters of the air conditioners between the rows.
And S333, controlling the inter-train air conditioner to execute the target operation mode by the control end under the condition that the target operation mode is feasible.
And S334, under the condition that the target operation mode is not feasible, the control end controls the inter-train air conditioner to be in standby.
In the embodiment of the disclosure, the target operation mode of the networking unit is determined according to the current operation parameters and the target operation parameters of all inter-row air conditioners in the networking unit. Wherein the operating parameters include one or more of return air parameters, environmental parameters, and the like. The target operation mode includes a cooling, heating, dehumidifying or humidifying mode, etc. For example, the current operation parameter includes a current ambient humidity, and the target operation mode is determined to be the dehumidification mode when the number of inter-train air conditioners of which the current ambient humidity is greater than the target humidity exceeds a preset number. And when the number of the inter-row air conditioners with the current environmental humidity smaller than the target humidity exceeds a preset number, determining that the target operation mode is the humidification mode. After the target operation mode of the networking unit is determined, the air conditioners between the columns judge whether the target operation mode is feasible or not according to the current operation parameters and the target operation parameters of the air conditioners between the columns. As previously described, after the target operation mode of the networking unit is determined, other operation modes are disabled. Although each inter-row air conditioner needs to execute the target operation mode, the control parameters of the inter-row air conditioner need to be determined by combining the self-detected operation parameters and the target operation parameters. At this time, there is a mismatch between the target operation mode and the current environmental demand for the individual inter-row air conditioner. In this case, the inter-row air conditioner performs the target operation mode, which causes competition to occur, thus standing by. And only when the current environmental requirement of the inter-train air conditioner is matched with the target operation mode, executing the target operation mode by the inter-train air conditioner, and otherwise, waiting. Therefore, competition of the inter-row air conditioners in the networking unit is avoided. Meanwhile, the scene requirement that the regional heat load may have difference is also met.
Optionally, in step S331, the control end determines a target operation mode of the networking unit according to current operation parameters and target operation parameters of all inter-row air conditioners in the networking unit, where the method includes:
and the control end acquires the current return air parameters of the air conditioners among the columns and calculates the average return air parameters of the current networking unit.
And the control end determines a target operation mode of the networking unit according to the average return air parameter and the target return air parameter.
In the embodiment of the disclosure, the current air return parameters detected by the air conditioners between the rows are obtained, and the average value of all the current air return parameters is calculated. And taking the average value as an average return air parameter of the networking unit. And then, determining a target operation mode of the networking unit based on the average return air parameter and the target return air parameter. Specifically, if the return air parameter includes the return air temperature, the target operating mode is determined to be the cooling mode when the average return air temperature is greater than the target return air temperature. And when the average return air temperature is lower than the target return air temperature, determining the target operation mode as the heating mode. And under the competition prevention mode, the target return air parameters in the networking unit are the same.
With reference to fig. 4, another method for group control of air conditioners between trains is provided in an embodiment of the present disclosure, which includes:
s401, under the condition that a plurality of inter-train air conditioners are networked, the control end determines a group control mode of a networking unit according to an application scene.
S402, under the condition that the group control mode of the networking unit is determined to be a stacking function mode, the control end selects any one inter-row air conditioner in the networking unit as a host and other inter-row air conditioners as slaves; determining the addresses of the host and the slave; wherein, the host computer is stored with target operation parameters.
And S431, the networking unit comprises a current networking unit and a standby networking unit, and the control end calculates the total control requirement according to the current operation parameters and the target operation parameters of all inter-column air conditioners in the current networking unit.
And S432, under the condition that the current networking unit can meet the total demand, the control end distributes the total demand to the available inter-row air conditioners in the current networking unit according to a preset principle, and controls the inter-row air conditioners to operate according to the distributed demand.
S433, the control end starts a standby networking unit under the condition that the current networking unit cannot meet the total requirement; and distributing the total demand to the available inter-train air conditioners in the current networking unit and the standby networking unit according to a preset principle, and controlling the inter-train air conditioners to operate according to the distributed demand.
In the embodiment of the disclosure, in the stacking function mode, the current operating parameters and the target operating parameters of all inter-column air conditioners in the current networking unit are obtained, and the total control requirement of the current networking unit is calculated. Specifically, the control demand of each inter-train air conditioner in the current networking unit can be calculated respectively, and the sum of the control demands of all the inter-train air conditioners is accumulated to serve as the total control demand. And if the current networking unit can meet the total control requirement, distributing the total control requirement to the available inter-train air conditioners in the current networking unit. And if the current networking unit cannot meet the total control requirement, starting the standby networking unit. And judging whether the current networking unit can meet the total control requirement or not by accumulating the sum of the maximum requirements of the available inter-row air conditioners in the current networking unit. Or, according to a preset distribution principle, for example, setting the required distribution amount X of the air conditioners between each row. The required number of inter-row air conditioners N is W/X, W being the total demand. And if N is larger than the number of the current networking unit, starting the standby unit. Meanwhile, the required amount may not be divisible. In this case, whether an air conditioner needs to be added or not can be determined according to the size of the remainder of the demand. If the demand remainder is greater than the demand threshold, the number of inter-row air conditioners is N + 1. Further, the control demand includes a cooling demand, a heating demand, a dehumidifying demand, and the like. The preset distribution principle can be an average principle, or preset demand distribution, or other principles.
In the group control mode, all inter-row spaces in the current networking unit are equivalent to a large inter-row air conditioner. Therefore, the uniform heat load of the region can be realized, and the resource waste caused by the competition of air conditioners between the columns in the unit is avoided. In addition, under the condition that the current networking unit can meet the total requirement, or the environmental parameters of the controlled target area meet the requirement, the standby networking unit carries out the standby mode. Specifically, when the total demand is issued to each inter-row air conditioner, the total demand is issued one by one according to the address of each inter-row air conditioner. The inter-row air conditioner of the standby networking unit does not participate in the calculation of the total control requirement, and the control is started in a delayed mode when the inter-row air conditioner is started.
Optionally, in step S431, the control end calculates a total control requirement according to the current operating parameters and the target operating parameters of all inter-train air conditioners in the current networking unit, including:
and the control end acquires the current return air parameters of the air conditioners among the columns in the current networking unit and calculates the average return air parameters.
And the control end calculates the total control requirement according to the average return air parameter, the target return air parameter and the number of the available inter-train air conditioners of the current networking unit.
