Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An outdoor unit emergency control method and an apparatus thereof according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of an emergency control method for an outdoor unit according to an embodiment of the present invention. The outdoor unit emergency control method can be used in a multi-split air conditioning system.
As shown in fig. 1, the emergency control method of the outdoor unit includes the following steps:
step 101, collecting state information of a first temperature sensor in an outdoor unit.
An environment temperature sensor, a coil temperature sensor, a compressor temperature sensor and the like are often arranged on the outdoor unit, and in the embodiment of the invention, any one of the environment temperature sensor, the coil temperature sensor and the compressor temperature sensor can be called as a first temperature sensor.
In the embodiment of the invention, the first temperature sensor in the outdoor unit can be monitored in real time to determine whether the first temperature sensor is in a normal state. Specifically, when the first temperature sensor is in the normal state, the acquired current temperature should be within a temperature range, and exceeding the temperature range may indicate that the first temperature sensor is in the abnormal state. Accordingly, first temperature sensor temperature information may be collected.
For example, when the first temperature sensor is an ambient temperature sensor, the ambient temperature of the first temperature ambient sensor may be collected as the state information.
As an example, when the first temperature sensor is in a normal state, the voltage or resistance value of the first temperature sensor should be stable within a certain range. Thus, the voltage and/or resistance of the first temperature sensor may be collected as state information of the first temperature sensor.
Therefore, in the embodiment of the present invention, the state information of the first temperature sensor includes temperature information, voltage information, resistance information, and/or the like.
In this embodiment, in order to ensure normal operation of each outdoor unit in the multi-split air conditioning system, state information of the first temperature sensor in the outdoor unit may be periodically collected. It is understood that, in order to find the first temperature sensor in an abnormal state in time, the acquisition period should not be set too long, and optionally, T of the acquisition period is marked, and then T may be 4min, for example.
And 102, judging whether the first temperature sensor is in an abnormal state or not according to the state information.
In this embodiment, when the acquired state information is different, the determination process of whether the first temperature sensor is in the abnormal state is different.
As a possible implementation manner of the embodiment of the present invention, when the state information is the resistance of the first temperature sensor, it can be understood that, when the first temperature sensor is in the normal state, the resistance value of the first temperature sensor should be within a preset resistance range, and optionally, the preset resistance range is marked as [ R [l,Rh]. Therefore, in this embodiment, the collected resistance and the preset resistance range [ R ] can be comparedl,Rh]Comparing, when the resistance is in the resistance range [ R ]l,Rh]When the resistance is within the range of R, the first temperature sensor is in normal statel,Rh]When the first temperature sensor is in the abnormal state, the first temperature sensor is judged to be in the abnormal state.
As another possible implementation manner of the embodiment of the present invention, when the state information is the voltage of the first temperature sensor, it can be understood that when the first temperature sensor senses the state informationWhen the device is in a normal state, the resistance value and therefore the voltage across the device should be within a predetermined range, for example, marking a predetermined voltage range as [ V ]l,Vh]. Therefore, in this embodiment, the collected voltage can be compared with the preset voltage range [ V ]l,Vh]Comparing, when the collected voltage is in the voltage range [ V ]l,Vh]When the voltage is not in the voltage range [ V ], the first temperature sensor is in a normal statel,Vh]When the first temperature sensor is in the abnormal state, the first temperature sensor is judged to be in the abnormal state.
As another possible implementation manner of the embodiment of the present invention, when the state information is temperature information of the first temperature sensor, it can be understood that, when the first temperature sensor is in a normal state, its temperature should be within a preset temperature range within a certain time period, and optionally, the preset temperature range is marked as [ T [, ]l,Th]. Therefore, in this embodiment, the temperature of the first temperature sensor may be acquired within a preset first time period, and then the maximum temperature and the minimum temperature within the first time period may be determined, for example, the minimum temperature is marked as TminMaximum temperature of Tmax。
It is understood that when the first temperature sensor is in a normal state, the amount or rate of change of the acquired temperature should not exceed a preset temperature deviation, and optionally the preset temperature deviation is marked as Δ T. Therefore, in this embodiment, the maximum temperature T may be setmaxAnd a minimum temperature TminTaking a difference, and obtaining a relative difference value between the two as | Tmax-TminThen, the relative difference | T may be comparedmax-TminComparing | T with a preset temperature deviation Delta T, and when | T is greater thanmax-Tmin|>At, it is determined that the first temperature sensor is in an abnormal state, and when Tmax-TminAnd when | ≦ Δ T, determining that the first temperature sensor is in a normal state.
Alternatively, the maximum temperature T may be setmaxAnd a temperature range of [ Tl,Th]By comparison, when the maximum temperature TmaxUpper limit value T of temperature rangehWhen the difference between the first and second values exceeds a preset first threshold, it may be determined that the first temperature sensor is in an abnormal state. Alternatively, the minimum temperature T may be setminAnd a temperature range of [ Tl,Th]By comparison, when the minimum temperature T isminWith a lower limit value T of the temperature rangelWhen the difference between the first and second values exceeds a preset second threshold value, it may be determined that the first temperature sensor is in an abnormal state.
And 103, if the first temperature sensor is judged to be in an abnormal state, correcting the first temperature information of the first temperature sensor by using the second temperature information of the second temperature sensor in the candidate outdoor unit so as to maintain the continuous operation of the multi-split air conditioning system.
The candidate outdoor units are outdoor units of which the second temperature sensors are not abnormal in the multi-split air-conditioning system; the second temperature sensor is the same type of temperature sensor as the first temperature sensor.
Optionally, when it is determined that the first temperature sensor is in an abnormal state, the first temperature information of the first temperature sensor may be corrected by using the second temperature information in the candidate outdoor unit, so as to maintain the multi-split air conditioning system to continue to operate.
As a possible implementation manner of the embodiment of the present invention, one of all candidate machines may be randomly selected as the target outdoor unit, or one of all candidate machines may be randomly selected as the target outdoor unit according to a certain rule. And then collecting second temperature information of a second temperature sensor in the target outdoor unit, and further replacing the first temperature information with the second temperature information.
According to the outdoor unit emergency control method, the state information of the first temperature sensor in the outdoor unit is collected, whether the first temperature sensor is in an abnormal state or not is judged according to the state information, and when the first temperature sensor is judged to be in the abnormal state, the first temperature information of the first temperature sensor is corrected by using the second temperature information of the second temperature sensor in the candidate outdoor unit, so that the multi-split air conditioning system is maintained to continue to operate. Therefore, when a first temperature sensor in the multi-split air-conditioning system breaks down, the first temperature information of the first temperature sensor can be corrected by using the temperature information of a second temperature sensor in the outdoor unit which is not in an abnormal state, so that the dynamic maintenance of the outdoor unit is realized, the normal operation of the multi-split air-conditioning system is ensured, and the use experience of a user is improved.
Further, in order to notify the relevant maintenance personnel of removing the fault, in this embodiment, alarm information may be sent when the first temperature sensor is in an abnormal state.
In the embodiment of the invention, in order to ensure the normal operation of each outdoor unit in the multi-split air-conditioning system, after the multi-split air-conditioning system is maintained to continue to operate, whether the time for the multi-split air-conditioning system to continue to operate reaches a preset second time period or not can be detected, whether the abnormality of the abnormal outdoor unit in the multi-split air-conditioning system is relieved or not can be detected, if so, the outdoor unit is continuously monitored, so that when the first temperature sensor in the abnormal state is found, the first temperature information of the first temperature sensor can be corrected in time by using the temperature information of the second temperature sensor in the outdoor unit which is not in the abnormal state, and the continuous operation of the multi-split air-conditioning system can be maintained. The above process is described in detail below with reference to fig. 2.

And step 204, judging whether an outdoor unit which is not in an abnormal state exists in the multi-split air conditioning system, if so, executing step 205, otherwise, executing step 203.
Step 205, determining whether the number of outdoor units not in an abnormal state in the multi-split air conditioning system is greater than or equal to 2, if so, executing step 207, otherwise, executing step 206.
And step 206, correcting the first temperature information of the first temperature sensor by using the second temperature information of the second temperature sensor in the outdoor unit which is not in the fault state, so as to maintain the multi-split air conditioning system to continue to operate.
Alternatively, when there is only one outdoor unit that is not in the failure state, the second temperature information of the second temperature sensor in the only outdoor unit that is in the normal state may be used to correct the first temperature information of the first temperature sensor, so as to maintain the multi-split air conditioning system to continue to operate.

Then, one of the candidate outdoor units can be selected in sequence to serve as a target outdoor unit, second temperature information of a second temperature sensor in the target outdoor unit can be collected, and the first temperature information can be replaced by the second temperature information.
As a third possible implementation manner of the embodiment of the present invention, the first temperature information may be replaced with an average value of the second temperature information of the second temperature sensors in all the candidate outdoor units. Specifically, the second temperature information of the second temperature sensors in all the candidate outdoor units may be collected, and then all the second temperature information may be averaged to obtain the target temperature information, so that the target temperature information is used to replace the first temperature information.
Alternatively, the first temperature information of the first temperature sensor may be corrected by another method, which is not limited thereto.
And step 208, detecting whether the time for the multi-split air conditioning system to continue to operate reaches a preset second time period or whether the abnormality of the abnormal outdoor unit is removed, if so, executing step 209, otherwise, executing step 206 or 207.
In the embodiment of the present invention, after the multi-split air conditioning system is maintained to continue operating, it may be further detected whether the time for the multi-split air conditioning system to continue operating reaches a preset second time period, if the time does not reach the second time period, the second temperature information of the second temperature sensor in the outdoor unit that is not in the failure state may be continuously used to correct the first temperature information of the first temperature sensor, and if the time reaches the second time period, step 209 may be triggered.
In the embodiment of the present invention, after the multi-split air conditioning system is maintained to continue operating, it may be further detected whether the abnormality of the outdoor unit in the multi-split air conditioning system is resolved, when it is detected that the abnormality is not resolved, the first temperature information of the first temperature sensor may be continuously corrected by using the second temperature information of the second temperature sensor in the candidate outdoor unit, and when it is detected that the abnormality is resolved, step 209 may be triggered.

Or, after the abnormality of the outdoor unit in the multi-split air conditioning system is resolved, the first temperature sensor may continue to operate normally, in this embodiment, the outdoor unit may also continue to be monitored, so that when the first temperature sensor in the abnormal state is found, the first temperature information of the first temperature sensor may be corrected in time by using the temperature information of the second temperature sensor in the outdoor unit not in the abnormal state, so as to maintain the continuous operation of the multi-split air conditioning system, and improve the user experience.
