determining a second updating parameter corresponding to the first updating parameter according to the first updating parameter, the first feedback information and the parameter condition;
and taking the second updating parameter, the first feedback information and the failure record as a third starting record.
In the embodiment of the invention, when first feedback information is received in a first time range, failure records used for representing the starting failure of the compressor are generated, if the number of the failure records is larger than a preset threshold value, a failure result used for representing the incapability of starting the compressor is generated and displayed, otherwise, a second updating parameter corresponding to the first updating parameter is determined according to the first feedback information and a preset parameter condition and is recorded in the starting record of the starting. According to the method, on one hand, when the number of the failure records does not exceed the preset threshold value, each start adopts the new start parameters generated in the last start and failure, so that the success rate of the start of the compressor can be improved, and the repair rate of the compressor is reduced; on the other hand, the number threshold value of the failure records is set, so that the compressor can be prevented from being started for unlimited times, and the starting efficiency of the compressor is improved.
Based on the compressor start-up control method shown in fig. 1, in one embodiment of the present invention,

the first type includes:
wherein, I1For characterizing the value of the first starting current in the second starting record, I2For characterizing the second start-up recordN is used for representing the starting times of the compressor;
when the first feedback information includes the third factor, step 106 determines a second update parameter according to the first update parameter, the first feedback information, and a preset parameter condition, including:

wherein, I3For characterizing the value of the first starting current in the second starting record, I4The third starting current value corresponding to the first starting current value in the second starting record is represented, and n is used for representing the starting times of the compressor;

the third firing current, the second firing frequency value, and the second firing ramp rate are included in the second update parameter.
In the embodiment of the invention, when the first feedback information comprises the first factor, the early warning information is generated and displayed, so that when the compressor fails to start due to other reasons except the second factor and the third factor, a user can timely make adjustment according to the first updating parameter and the first feedback information in the early warning information, thereby further improving the success rate of starting the compressor. When the parameter condition includes a second factor, a second startup current value is generated from the first startup current value and the first pattern in the second startup record and included in the second updated parameter. And when the parameter condition comprises a third factor, generating a third starting current value according to the first starting current value and a second equation in the second starting record, determining a second starting frequency value and a second starting rising rate according to a first starting frequency value and a first starting rising rate in the first updating parameter and a preset adjusting range, and including the third starting current, the second starting frequency value and the second starting rising rate in the second updating parameter. Therefore, the second updating parameter is obtained by adjusting the first updating parameter according to the parameter condition and the first feedback information, and the success rate of starting the compressor can be improved by starting the compressor by adopting the second updating parameter.
It is understood that, in the embodiment of the present invention, when the first feedback information includes the first factor, the generated warning information may be recorded in the currently activated start-up record.
Based on the compressor start control method shown in fig. 1, in an embodiment of the present invention, after determining whether the first start record exists in the pre-created database in step 101, the method may further include the following steps:
step A1: if the first starting record does not exist in the database, acquiring a first starting parameter which is stored in advance so as to enable the compressor to be started by adopting the first starting parameter;
step A2: judging whether second feedback information from the compressor is received within a first time range, if so, executing step A3, wherein the second feedback information comprises a reason for representing the failed starting of the compressor by using the starting parameters;

step A5: and generating and displaying a failure result.
In the embodiment of the invention, when a first starting record does not exist in the database, namely the compressor is started for the first time during the power-on period during the starting, the prestored first starting parameter is obtained, so that the compressor is started by adopting the first starting parameter, the failure record is generated when the starting fails, and if the number of the failure records does not exceed the preset threshold value, the first starting parameter is adjusted according to the second feedback information and the parameter condition to obtain a third updating parameter, and the third updating parameter is recorded in the starting record for storage; and if the number of the failure records exceeds a preset threshold value, generating a failure result and displaying the failure result. Therefore, when the first start of the compressor fails during the current power-on period, the first start parameter is adjusted to obtain a third update parameter so as to enable the compressor to be used for the next start.
Based on the compressor start-up control method shown in fig. 1, in an embodiment of the present invention, after determining whether the first feedback information from the compressor is received within the preset first time range in step 105, the following steps may be further included:
if the first feedback information is not received within the first time range, judging whether third feedback information used for representing the successful start of the compressor is received within a preset second time range;
if so, generating a success record for representing the successful start of the compressor, and storing the success record, the first updating parameter, the third feedback information and the identification information as a fifth start record;
and if not, reading the first updating parameter in the second starting record so as to enable the compressor to start by adopting the first updating parameter.
In the embodiment of the invention, when the first feedback information is not received in the first time range, if the third feedback information is not received in the preset second time range, the first updating parameter in the second starting record is read again, so that the compressor is started by adopting the first updating parameter, otherwise, a successful record for representing the successful start of the compressor is generated, and the successful record, the first updating parameter, the third feedback information and the identification information are stored as a fifth starting record. Therefore, on one hand, the first updating parameter is read again when the third feedback information is not received, so that the compressor is started by adopting the first updating parameter, negative effects caused by failure in reading the first updating parameter and the like are avoided, and the starting efficiency of the compressor is improved; on the other hand, the starting parameters adopted when the compressor is started successfully are recorded in the starting record, so that the compressor can be used for the next starting, and the success rate of starting the compressor is further improved.
It should be noted that, after the success record for indicating the successful start of the compressor is generated, the number of the current failure records is cleared. For example, during the current power-on period of the compressor, if all the previous 3 starts fail, the number of the failure records is 3, and after the fourth start succeeds, the number of the current failure records is recorded as 0. If the 5 th startup fails, the number of current failure records is 1.
Based on the compressor start control method shown in fig. 1, in an embodiment of the present invention, after determining whether the identification information for indicating successful start of the compressor exists in the second start record in step 103, the following steps may be further included:
and if the identification information exists in the second starting record, reading the second starting parameter in the second starting record so as to enable the compressor to start by adopting the second starting parameter.
In the embodiment of the invention, if the identification information exists in the second starting record, the second starting parameter in the second starting record is read, so that the compressor is started by adopting the second starting parameter. Therefore, the starting parameters used when the starting is successful and the last starting are adopted, so that the starting success rate of the compressor can be improved.
In order to more clearly illustrate the technical solution and advantages of the present invention, a detailed description is provided below of a compressor start-up control method provided by an embodiment of the present invention, as shown in fig. 2, the method may include the following steps:
step 201: and judging whether a first starting record exists in a pre-established database in a preset period, if not, executing step 202, otherwise, executing step 203.
In this step, each time the compressor is started, a corresponding start record is generated and stored in the pre-created database, that is, the number of the start records is the number of start times of the compressor after the power-on. The first start record is generated according to the first start of the external compressor after the external compressor is powered on, so whether the first start record is the first start of the compressor after the external compressor is powered on can be judged through whether the first start record exists in the database.
Step 202: and acquiring a first pre-stored starting parameter so as to start the compressor by adopting the first starting parameter, and executing step 207.
Step 203: and acquiring a second starting record with the shortest time interval with the current time point from the database.
In this step, the second start record is one of all start records of the compressor during the current power-on period, which has the shortest time interval with the current time, that is, the latest start record in the date.
For example, when 6 start records generated during the current power-on period are stored in the database, when the compressor is started for the 5 th time, the start record generated during the 4 th time is the second start record of the current start.
For another example, when 1 start record generated during the current power-on period is stored in the database, and when the compressor is started for the 2 nd time, the start record is the second start record.
Step 204: and judging whether identification information for representing successful starting of the compressor exists in the second starting record, if so, executing the step 205, otherwise, executing the step 206.
Specifically, the identification information may be, for example, a startup success flag set to 1.
Step 205: and reading the second starting parameter in the second starting record so as to start the compressor by using the second starting parameter, and executing step 207.
For example, if the second start record is generated by starting the compressor for the 5 th time during the current power-on period, when the starting for the 5 th time is successful, the second start record includes the starting parameter used by the starting for the 5 th time, a successful record for representing the success of the starting for the 5 th time of the compressor, the feedback information for representing the success of the starting using the starting parameter, and the identification information for representing the successful starting of the compressor, where the second starting parameter is the starting parameter used by the starting for the 5 th time.
Step 206: and reading the first updating parameter in the second starting record so as to enable the compressor to start by adopting the first updating parameter.
For example, if the second start record is generated by starting the compressor for the 5 th time during the current power-on period, when the 5 th time fails to start, the second start record includes a failure record for representing the start failure of the compressor, feedback information for representing the start failure using the start parameter, and a new start parameter generated after adjustment according to the start parameter, where the first update parameter is the new start parameter.
Step 207: and judging whether failure feedback information from the compressor is received within a preset first time range, if so, executing step 208, otherwise, executing step 214.
In this step, the failure feedback information includes causes for characterizing the start failure of the compressor, such as a cause of step loss, a speed estimation lower limit cause, a cause of overpower, a cause of overcurrent matching the cause of step loss, a cause of overcurrent not matching the cause of step loss, and other causes besides the above.
Specifically, in step 202, the failure feedback information is used to represent the reason for the failed start of the compressor using the first start parameter, and is recorded as feedback information 1.
Specifically, in step 205, the failure feedback information is used to represent the reason for the failed start of the compressor using the second start parameter, and is recorded as feedback information 2.
Specifically, in step 206, the failure feedback information is used to represent the reason for the failed start-up of the compressor using the first update parameter, and is denoted as feedback information 3.
Step 208: and generating failure records for representing the starting failure of the compressor, judging whether the number of the failure records is greater than a preset threshold value, if so, executing the step 209, and otherwise, executing the step 210.
Step 209: and generating and displaying a failure result for representing that the compressor cannot be started, and ending the current process.
