In the related technology for detecting the communication error rate of the frequency converter, the communication error rate is usually counted by using other external equipment, so that the load cannot follow the change of the actual condition to monitor the error rate in real time, and the real-time performance and the authenticity of data are influenced. In order to solve all or part of the above problems, an embodiment of the present application provides a method for controlling a load based on an error rate of a frequency converter, as shown in fig. 1, the method includes:
and S101, acquiring the error rate of an external machine and the error rate of an internal machine of the frequency converter.

The inverter (an inverter in an air conditioner) may enter an operation state according to a user's control. The inverter may include an inner unit and an outer unit. After the frequency converter enters the running state, the internal machine and the external machine carry out data interaction in a communication mode, and the internal machine or the external machine can actively initiate an error rate monitoring request to the opposite side. Alternatively, an external unit may be used as a master for initiating the bit error rate monitoring request. And after the error rate monitoring is finished, the air conditioner frequency converter acquires the error rate of the external machine and the error rate of the internal machine.
And S102, taking the larger code rate of the outer machine error rate and the inner machine error rate as the reference error rate of logic intervention.
After the error rate of the external machine and the error rate of the internal machine are obtained, the two values can be compared, and the larger value is used as the reference error rate of logic intervention.
And step S103, determining an error rate interval where the reference error rate is located, and executing logic intervention matched with the error rate interval on load operation logic of the external unit.
And obtaining the bit error rate interval in which the currently determined reference bit error rate is positioned according to the determined reference bit error rate. In the embodiment of the application, a plurality of error rate intervals can be set according to the error rate value obtained through past empirical calculation, then the error rate interval in which the current reference error rate value falls is determined, and finally, logic intervention of preset matching is performed on the load operation logic execution interval of the external unit.
In the embodiment of the application, no external equipment is needed, in the running process, the air-conditioning frequency converter monitors the error rate of the internal unit and the error rate of the external unit in real time, the reference error rate of logic intervention is determined according to the monitored error rate of the internal unit and the monitored error rate of the external unit, and then the intervention control is dynamically carried out on the load according to the monitoring result of the error rate interval in which the reference error rate is located, so that the error code caused by load interference can be eliminated, and the reliability, the safety and the accuracy of load action are improved.
Based on the content of the above embodiments, as an alternative embodiment: determining an error rate interval in which the reference error rate is positioned, and performing logic intervention matched with the error rate interval on load operation logic of the external unit, wherein the logic intervention comprises the following steps:
under the condition that the reference error rate is smaller than or equal to the first numerical value of the error rate interval, controlling the external unit to continue to execute according to the load operation logic;
after the external machine is continuously detected for the preset times, if the reference error rate is between the first numerical value and the third numerical value of the error rate interval, performing corresponding logic intervention of frequency reduction or shutdown on the frequency converter according to a preset scheme;
and after the external machine is continuously detected for the preset times, if the reference error rate is greater than or equal to a third numerical value of the error rate interval, the frequency converter enters a shutdown state.
In this embodiment, the bit error rate interval may be divided into a plurality of sub-intervals by setting a plurality of values, where the values may be: a first value, a second value, and a third value. And under the condition that the reference error rate is less than or equal to the first value of the error rate interval, controlling the external unit to continue to operate logically according to the load, namely when Er is less than or equal to e11, controlling the error rate to be within a normal error range and not performing logic intervention. Er is a reference bit error rate, e11 is a first value, and optionally e11 is 5%.
After the external machine is subjected to N1 times of error rate detection continuously, if the reference error rate is between the first value and the third value of the error rate interval, corresponding down-conversion or shutdown logic intervention can be performed on the frequency converter according to a preset scheme, optionally, when e11 is greater than Er and less than or equal to e13, the reference error rate of N1 times of error rate detection continuously is still between the first value and the third value of the error rate interval, and the compressor of the frequency converter can be subjected to down-conversion at a certain speed; and entering a frequency reduction interference prognosis, continuously detecting the error rate for N1 times, and if the reference error rate is still between the first value and the third value of the error rate interval, entering a shutdown state of the frequency converter. e13 is a third value, optionally e13 ═ 10%.
Alternatively, as in fig. 2, a second value e12 may be set between the first value e11 and the third value e13, optionally e12 being 8%; therefore, when e11 is larger than Er which is smaller than or equal to e12, N1 times of error rate detection are carried out continuously, the reference error rate is still between the first value and the second value of the error rate interval, the frequency of the compressor enters the frequency limit, the frequency is controlled to be the current frequency, and the frequency can be controlled to be within a certain range, such as the frequency value is 20-25. After entering frequency-limiting intervention, if the error rate detection is performed for N1 times continuously, and the reference error rate is still between the first value and the second value of the error rate interval, the compressor may be down-converted at a certain speed, where the down-conversion may be to reduce the frequency to a certain value. And entering a frequency reduction interference prognosis, continuously detecting the error rate for N1 times, and if the reference error rate is still between the first value and the second value of the error rate interval, entering a shutdown state of the frequency converter.
When e12 < Er < e13, if the error rate is detected for N1 times continuously, the reference error rate is still between the second value and the third value of the error rate interval, and the compressor can reduce the frequency at a certain speed; entering the frequency reduction interference prognosis, if the error rate reference is still between the second value and the third value of the error rate interval for N1 times of error rate detection, the frequency converter can enter a shutdown state.
And when Er is more than or equal to e13, if the reference error rate is still more than or equal to the third value after N1 times of error rate detection, the error rate is considered to be overlarge, and the machine is directly stopped.
It should be noted that the preset scheme in the embodiment of the present application refers to a logical intervention operation performed by the external unit according to the interval where the Er value is located, where the logical intervention includes frequency limiting, frequency reducing, and shutdown; e11, e12 and e13 are preset error rate interval values, wherein e11 is more than e12 is more than e 13.
In the embodiment of the application, the error rate is continuously detected for multiple times, so that the obtained reference error code value is more accurate, and the reliability, the safety and the accuracy of the load action of the frequency converter can be better improved by executing the logic intervention operation of frequency limitation, frequency reduction or shutdown on the frequency converter according to the currently obtained reference error code value.
Based on the content of the above embodiments, as an alternative embodiment: before determining the bit error rate interval in which the reference bit error rate is located, the method further includes:
acquiring a ratio of error communication data of the frequency converter to total communication data within a preset time, and determining at least one error rate;
and arranging the at least one bit error rate according to the sequence of the numerical values from small to large to generate at least one bit error rate interval.
A preset time may be set according to the historical development experience of the technician. A plurality of error rates can be set according to the ratio of error communication data to total communication data in the data interaction process of the frequency converter within the preset time, and then the error rates are arranged according to the sequence of numerical values from small to large to generate at least one error rate interval. For example, the error rate is three, which is 5%, 8%, and 10%, respectively, then the error rate interval may be set to "≦ 5%" for the first interval, "(5%, 8% ]" for the second interval, "(8% -10%)" for the third interval, and "≧ 10%" for the fourth interval.
In the embodiment of the application, a plurality of error rate values are obtained according to the historical research and development experience of technicians, a plurality of error rate intervals are further set, corresponding logic intervention is executed after the error rate intervals with the reference error rates falling into the error rate intervals are determined, the accuracy of the external unit for regulating and controlling the load of the air conditioner can be improved, and the safety of products is improved through intervention control.
