Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning control, and in particular to a shutdown control method, device, computer equipment and storage medium for an air conditioning system. Background Art

[0002] Social development and technological progress have brought about a continuous improvement in the living standards of residents, but have also had a serious impact on the global climate. Therefore, air conditioners have become the preferred home appliance for most families across the country. The application of air conditioners is becoming more and more extensive, and the safety, reliability, comfort, and energy saving of air conditioners are becoming more and more the focus of air conditioner research and development and user experience. While ensuring comfort and energy saving, the safety, reliability and stability of the system must also be guaranteed. The wider the application of air conditioners, the higher the control requirements for air conditioners, among which the various protection control requirements for air conditioners are more obvious. When the operating status data of the air conditioning system, such as temperature, pressure, and current, exceeds the normal operating range for some reason and needs protection control, the system control software will control the air conditioning system to increase or decrease the fan speed, adjust the operating frequency of the compressor (variable frequency model), stop the compressor, etc. When the status data returns to normal, the system will enter normal operation again.

[0003] In order to better protect the air-conditioning system, improve safety and reliability, and extend the life cycle of the air-conditioning, the number of shutdowns for the above types of protection will be counted separately in the software control of exhaust temperature protection, current protection, high-voltage switch disconnection protection, and low-voltage switch disconnection protection. When a certain type of protection shutdown reaches a certain number of times within a certain period of time, this protection will be locked by the software. Even if the status data returns to normal, it will not automatically return to normal, and the air-conditioning system will no longer be able to operate. It can only be started again after power failure and then power on again.

[0004] However, in the current shutdown control method of the air-conditioning system, power-off protection is usually performed when the cumulative number of shutdowns within a fixed time period after the first protective shutdown reaches a preset number of times. When the cumulative number of shutdowns within the fixed time period does not reach the preset number of times, the number of shutdowns and the cumulative time are all reset to zero and counted and timed again. Therefore, there will be a problem of insufficient monitoring of the shutdown status of the air-conditioning system, resulting in defects in the safety and reliability of the air-conditioning system.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] Figure 1FIG. 1 is a flow chart of a shutdown control method for an air conditioning system provided by an embodiment of the present invention; Figure 1 As shown, the control method includes:

[0023] Step S101, obtaining the current cumulative number of shutdowns and the current cumulative shutdown duration according to the fault type of the current shutdown fault and the current shutdown time;

[0024] In this embodiment, the fault types include but are not limited to exhaust temperature faults, voltage and current faults, and switch status faults; the air-conditioning system includes an electronic control device for real-time collection of operating status parameters such as compressor schedule temperature, current value, and switch status, and using the operating status parameters as judgment conditions for air-conditioning system protection control; when a certain parameter reaches a certain threshold or a closed switch is disconnected, the air-conditioning system needs to shut down for protection, and different shutdown protections accumulate the number of shutdowns respectively; wherein the current accumulated shutdown duration starts with the first shutdown time in the current accumulated shutdown times and ends with the current shutdown time.

[0025] Step S102, if the current cumulative downtime duration is greater than the preset cumulative downtime duration, the segmented cumulative duration from each downtime moment to the current downtime moment is obtained according to the downtime moment corresponding to each downtime fault in the current cumulative downtime duration and the current downtime moment.

[0026] In this embodiment, if the current cumulative downtime duration is less than or equal to the preset cumulative duration, and the current cumulative number of downtimes is less than the preset cumulative number, the current cumulative number of downtimes is accumulated.

[0027] Optionally, when the cumulative duration of all segments is greater than the preset cumulative duration, the current downtime is used as the starting time for calculating the next cumulative downtime, and the current downtime is used as the starting number for calculating the next cumulative downtime. Optionally, when the current cumulative downtime is less than the preset cumulative number, and the current cumulative downtime is equal to the alarm fault number, the air conditioning system is controlled to send an alarm signal.

[0028] It should be noted that within a certain period of time T (T is a constant), the number of shutdowns for a certain protection is less than N (N is an integer constant). When the parameters or switch quantities of the air conditioner return to normal, the protection returns to normal and the air conditioning system can continue to operate. Within the T time, if the number of shutdowns for a certain protection reaches N times, the protection shutdown state is locked, and the air conditioner will not be able to continue to operate and can only be restarted after power failure.

[0029] If the current cumulative downtime duration is greater than the preset cumulative duration, calculate the segmented cumulative duration of the first downtime time and the current downtime time, the segmented cumulative duration of the second downtime time and the current downtime time, and so on, until the segmented cumulative duration of the last downtime time and the current downtime time is obtained.

[0030] Step S103, comparing all the segment cumulative durations with the preset cumulative duration respectively to obtain a target segment cumulative duration, wherein the target segment cumulative duration is the segment cumulative duration that is smaller than and closest to the preset cumulative duration among all the segment cumulative durations.

[0031] In this embodiment, a segmented cumulative duration that is less than and closest to the preset cumulative duration is selected from all segmented cumulative durations. For example, the preset cumulative duration is 30 minutes, the segmented cumulative duration from the first shutdown to the current shutdown in the current cumulative number of shutdowns is 40 minutes, the segmented cumulative duration from the second shutdown to the current shutdown is 35 minutes, the segmented cumulative duration from the third shutdown to the current shutdown is 28 minutes, and the segmented cumulative duration from the fourth shutdown to the current shutdown is 25 minutes. Since 28 minutes and 25 minutes are both less than the preset cumulative duration of 30 minutes, and 28 minutes is the closest to the preset cumulative duration, the segmented cumulative duration corresponding to the third shutdown is the target segmented cumulative duration.

[0032] Step S104, taking the target downtime time corresponding to the target segment cumulative duration as the starting time for calculating the next cumulative downtime duration, and taking the number of downtimes corresponding to the target downtime time as the starting number for calculating the next cumulative number of downtimes.

[0033] In this embodiment, the time between every two protection shutdowns is first dynamically recorded, that is: when a certain protection is shut down for the first time, the time variable T1 is used to start timing; when it is shut down for the second time, the time variable T2 is used to start timing, and T1 ends timing; when it is shut down for the third time, the time variable T3 is used to start timing, and T2 ends timing..., when it is shut down for the Kth time, the time variable TK is used to start timing, and TK-1 ends timing..., when it is shut down for the Lth time, the time variable TL is used to start timing, and TL-1 ends timing..., when it is shut down for the Nth time, TN-1 ends timing (K, L are positive integers, and 1≤K<L<N, the same below).

[0034] Secondly, dynamically adjust the cumulative time and cumulative number of protection shutdowns, that is, if T1+…+TK…+TL-1≥T when the Lth shutdown just happened, but TK…+TL-1<T, and TK-1+TK…+TL-1≥T, then the timing variable TK at the Kth shutdown is used as the first time value of a new round of cumulative timing, and the timing variable TL at the Lth shutdown starts timing. At this time, the cumulative number of shutdowns is (L-K+1); this protection shutdown state will not be locked. When the parameters or switch quantities of the air conditioner return to normal, the protection returns to normal and the air conditioner can continue to run; if T1+T2+T3…+TN-1<T when the Nth shutdown just happened, the protection shutdown state is locked, the air conditioner will not be able to continue to run, and can only be restarted after power failure.

[0035] It should be noted that, according to the above example, since the duration from the first shutdown and the second shutdown in the current cumulative number of shutdowns to the current shutdown is greater than the preset cumulative duration, it is necessary to clear the shutdown time and shutdown count related to the first shutdown and the second shutdown, and use the shutdown time of the third shutdown as the starting time of the next cumulative shutdown duration, and use the third shutdown as the first shutdown of the next cumulative number of shutdowns, so as to achieve the purpose of dynamically adjusting the cumulative shutdown duration and the cumulative number of shutdowns.

[0036] Compared with the prior art, the beneficial effects of this embodiment are:

[0037] This embodiment compares the cumulative downtime of all segments with the preset cumulative time, obtains the target segment cumulative time that is less than and closest to the preset cumulative time according to the comparison result, and then dynamically adjusts the cumulative downtime and the cumulative downtime of the next judgment cycle according to the start time and the number of shutdowns of the target segment cumulative time. Compared with the prior art of resetting all the counting and timing, the monitoring of the air conditioner shutdown status is more comprehensive, faults can be discovered in time and fast after-sales service can be obtained, the safety and reliability of the air-conditioning system is improved, and the life cycle of the air-conditioning product is extended.

[0038] Figure 2 FIG. 2 is a flow chart of another shutdown control method for an air conditioning system provided by an embodiment of the present invention; Figure 2As shown, suppose there is an air conditioning system whose electronic control system includes a low-voltage switch input, and the electronic control system of the air conditioner monitors the state of the low-voltage switch input in real time. If the low-voltage switch is closed, the state of this input is normal; if the low-voltage switch is disconnected, the state of this input is abnormal, and the low-voltage switch disconnection protection will be generated. The air conditioning system needs to shut down. The number of shutdowns and the cumulative time will be accumulated from the first low-voltage switch disconnection protection shutdown. If this protection shutdown occurs 3 times within 30 minutes, the software will lock this protection, and the air conditioning system needs to be powered off before it can be restarted. The electronic control system of the air conditioner monitors the state of the low-voltage switch input in real time, and the software sets the following variables: 1. Low-voltage switch disconnection protection, after the system shuts down, the cumulative number of system shutdowns variable C; 2. Low-voltage switch disconnection protection for the first time, after the system shuts down, the timing variable T1 starts; 3. Low-voltage switch disconnection protection for the second time, after the system shuts down, the timing variable T2 starts.

[0039] In this embodiment, Figure 2 As shown in FIG. 1 , the shutdown control process of the air conditioning system specifically includes the following steps:

[0040] 1. Is the number of shutdowns of the low-voltage switch disconnect protection system 1 (C == 1)? If yes, go to 2; if no, go to 4;

[0041] 2. Is T1 greater than or equal to 30 minutes? If so, go to step 3; otherwise, increment the variable T1 by 1 and exit;

[0042] 3. Clear C, clear T1, and exit;

[0043] 4. Is the number of shutdowns of the low-voltage switch disconnect protection system 2 (C == 2)? If yes, go to step 5; if no, go to step 7;

[0044] 5. Is T1+T2 greater than or equal to 30 minutes? If so, proceed to step 6; otherwise, increment the variable T2 by 1 and exit;

[0045] 6. C is assigned a value of 1, the current value of T2 is assigned to T1, T2 is cleared, the variable T1 is incremented by 1, and then exit;

[0046] 7. Is the number of shutdowns of the low-voltage switch disconnect protection system 3 (C == 3)? If yes, go to 8; if no, exit;

[0047] 8. Clear T1, clear T2, lock protection, and exit.

[0048] The above embodiments have been verified in existing products and are reasonable and reliable. The above method controls the air conditioning system after protection shutdown, which makes up for the defects of the previous control method, can better protect the air conditioning system, find faults in time to obtain fast after-sales service, improve the safety and reliability of the air conditioning system, and extend the life cycle of the air conditioning product.
