Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.
An embodiment of the present invention provides a method for controlling power consumption of an air conditioner, and is a flowchart of a preferred embodiment of the method for controlling power consumption of an air conditioner, shown in fig. 1, and the method includes steps S11 to S13:
s11, grouping a plurality of relays in the air conditioner in a mode that M relays are taken as a group to obtain N relay control groups; wherein M is more than or equal to 1 and less than or equal to 2, and N is more than 0;
step S12, allocating a first driving time to each relay in each relay control group, and controlling each relay to be closed in the corresponding first driving time according to a preset first driving signal; the first driving time corresponding to each relay is not overlapped;
step S13, after the first driving time passes, distributing second driving time to each relay in each relay control group according to a preset time period, and controlling each relay to be closed or opened in the corresponding second driving time according to a preset second driving signal; the second driving time comprises power-on time and power-off time, and the power-on time corresponding to the relays in the same relay control group is not overlapped; the duty ratio of each relay is less than 1, and when M is 2, the sum of the duty ratios of 2 relays in the same relay control group is 1;
specifically, with reference to fig. 2 and the above-mentioned embodiment, a plurality of relays in the air conditioner are grouped by grouping two relays into one group, when the grouping is performed by grouping that two relays are not enough, one relay is grouped into one group to obtain N relay control groups, taking relay control group 1 as an example, according to a first driving signal, the first relay RY1 is controlled to be closed within a corresponding first driving time, according to the first driving signal, the second relay RY2 is controlled to be closed within a corresponding first driving time, and the first driving time corresponding to the first relay RY1 is not overlapped with the first driving time corresponding to the second relay RY2, so that only one relay enters a pull-in state within each driving time, the impact of an initial current is reduced, and the probability of damage to the power supply line is further reduced; secondly, after the first driving time passes, distributing second driving time for each relay in a preset time period, controlling each relay to be closed in corresponding power-on time according to a preset second driving signal, and controlling each relay to be opened in corresponding power-off time, wherein the power-on time corresponding to the relays in the same relay control group is not overlapped; it should be noted that the attraction state refers to the opening process from the disconnection to the attraction of the relay; the non-overlapping of the first driving time means that there is only one first driving time in the same time period, and as can be seen from fig. 2, there is no overlapping time period between the first driving time corresponding to the first relay RY1 and the first driving time corresponding to the second relay RY 2.
In a further preferred embodiment, the duty ratio of each relay is 50%, and the duty ratio corresponds to a PWM carrier frequency between 5K and 20K; wherein, the duty ratio of the relay refers to the duty ratio of a PWM driving signal (i.e., a second driving signal) that controls the relay to be closed or opened; it should be noted that, in the process of implementing the present invention, the inventor finds that the relay maintaining voltage is at least 40% to 50% of the rated voltage, and the excessively low PWM duty ratio is not favorable for the relay to maintain the pull-in state, so that the pull-in maintaining duty ratio of each relay of the embodiment is 50% which is favorable for ensuring the reliability of the relay, so that the relay can stably operate.
In a further preferred embodiment, the supply voltage corresponding to the first driving signal is greater than the supply voltage corresponding to the second driving signal; it should be noted that, because the initial pull-in stage of the relay usually requires more than 75% of the rated working voltage, and the pull-in maintaining stage after the initial pull-in only requires 40% of the rated voltage, the power supply voltage corresponding to the second driving signal of the present invention is lower than the power supply voltage corresponding to the first driving signal, and it is not necessary to keep more than 75% of the rated working voltage all the time, so as to further reduce the power consumption of the power supply.
In a further preferred embodiment, the first driving time corresponding to each relay is the same; wherein the first driving time ranges from 200ms to 800 ms.
In another preferred embodiment, controlling each relay to be closed or opened within a corresponding second driving time according to a preset second driving signal specifically includes:
distributing corresponding power-on time and power-off time for each relay according to each second driving time and the duty ratio of each relay in the relay control group corresponding to each second driving time; and controlling each relay to be closed within corresponding power-on time and to be opened within corresponding power-off time according to the second driving signal.
Specifically, with reference to fig. 2 and the above-described embodiment, according to the duty ratios of the first relay RY1 and the second relay RY2 being both 50%, the energization time and the deenergization time of the first relay RY1 and the second relay RY2 are the same, since only one relay can be controlled to be closed per energization time, when the first relay RY1 is energized, the power supply to the second relay RY2 is stopped, in other words, when the first relay RY1 is in the high-level output state, the second relay RY2 is in the low-level output state; when the first relay RY1 is in the low level output state, the second relay RY2 is in the high level output state; note that the time period in fig. 2 is the same as the second driving time.
In yet another preferred embodiment, the method further comprises:
after the first driving time passes, judging whether the actual power-off time of each relay in each relay control group is greater than a preset time threshold value;
if the actual power-off time of at least one relay is larger than a preset time threshold, the relay is removed from the corresponding relay control group;
and if the actual power-off time of each relay in each relay control group is not greater than the preset time threshold, each relay still remains in the corresponding relay control group.
Through carrying out real-time supervision to each relay in the relay control group, when the actual outage time of relay is greater than predetermined time threshold, show that the relay is in unoperated state in a certain time, reject the relay that is in unoperated state from the relay control group that corresponds to reduce the operation subassembly, and then improve the distribution efficiency of resource.
In yet another preferred embodiment, the method further comprises:
judging whether each relay control group is provided with two relays or not;
if only one relay exists in the K1 th relay control group and the K2 th relay control group, the relays in the K2 th relay control group are combined into the K1 th relay control group; wherein, K1 is more than or equal to 1 and K2 is more than or equal to N;
if there are two relays in each relay control group, it is not necessary to combine the relay control groups.
Specifically, with reference to fig. 3 and the above-mentioned embodiment, there is only one first relay RY1 in the relay control group 1, and there is only one third relay RY3 in the relay control group 2, and according to the numbering sequence of the relay control groups, the third relays RY3 in the relay control group 2 are combined into the relay control group 1, and when combined, the third relays RY3 are kept in a continuous energization state, in other words, a high level state. It should be noted that the time for keeping the high level state is not shorter than the PWM duty cycle of the relay, and the duty cycle of the third relay RY3 in this embodiment is 50%, so the time for keeping the high level state is not lower than 50%; when the first relay RY1 is converted from low level to high level, the third relay RY3 is converted from high level to low level, so that only one relay in each power-on time of the combined relay control group is in a closed state, power consumption of the power supply is reduced, and electric energy is saved. The combination of the relay control groups is beneficial to reducing the number of the relay control groups, is easy to manage and distribute control resources, and improves the distribution efficiency of the resources. Correspondingly, when no relay exists in the relay control group, the relay control group can be directly removed from the system, and the number of the relay control groups is reduced. Correspondingly, when a relay needing to be controlled is newly added in the air conditioner, the relay is preferentially combined into a relay control group with only one relay, and a new relay control group is not required to be reestablished, so that the number of the relay control groups is reduced, and the management and the distribution of control resources are easy. It should be noted that, after the relays in the relay control group 2 have been merged into the relay control group 1, the relay control groups are reordered, for example, the original relay control group 3 is changed to the relay control group 2, the original relay control group 4 is changed to the relay control group 3, and so on.
