Specifically, before the detection personnel starts to detect the outdoor power supply, the model information, rated parameters (including, but not limited to, rated voltage, rated current, rated resistance, rated power), test type and test time (i.e. charging time or discharging time) of the outdoor power supply are recorded.
When it is determined that the test type is a charge test or a discharge test (hereinafter, charge test or discharge test will be simply referred to as charge-discharge test for the sake of understanding), step S2 is performed. When it is determined that the test type is not the charge-discharge test, the execution of step S2 is stopped.
More specifically, when a inspector starts up and inspects the outdoor power supply, the test type of the outdoor power supply is obtained, and if the test type is determined to be a charging test or a discharging test, relevant parameters of the outdoor power supply are obtained.
In the case where the outdoor power supply is subjected to the charge and discharge test for the first time, since there is no history test data, the rated parameters of the outdoor power supply of the model can be acquired as a reference object. When the outdoor power supply of the model is subjected to the charge and discharge test before, the historical parameters in the historical test record can be used as reference objects, so that the follow-up judgment of whether the outdoor power supply of the model has abnormal heating or not can be facilitated.

In one possible implementation, when the nominal parameter is obtained in step S2, step S3 specifically includes: based on the rated parameter, the rated heating value of the outdoor power supply associated with the model information is calculated, and the rated heating value is a heating model.
Specifically, the heating value=the square of the rated current×the rated resistance.
For example: the rated current of the outdoor power supply is 2A, and the rated resistance is 8Ω, and then the rated heating value q=2ζ8Ω=32w of the outdoor power supply.
In another possible embodiment, referring to fig. 3, in case the model of outdoor power source has a history of tests, the following steps are performed:
a1, analyzing the historical parameters based on the historical parameters to obtain a plurality of groups of historical heating values and a plurality of groups of historical charging and discharging time. Each set of historical heating values was set to Q in watts. Each group of historical charge and discharge time is set as t, and the unit is min.
A2, fitting a binomial formula, wherein the binomial formula is Q=at 2 +bt+c, a, b, c are parameters in the binomial formula.
The binomial formula is adopted as a heating model to simulate the heating trend, so that the heating process of the outdoor power supply in the test process can be accurately described by using a simple mathematical expression. In addition, the binomial formula can also effectively reflect complex heating characteristics, such as heating speed, heating time, etc., and can effectively simulate actual heating conditions.
And A3, calculating a parameter a, a parameter b and a parameter c in a binomial formula based on the historical heating value and the historical charge-discharge time.
Specifically, step A3 includes:
a31, marking the historical charge and discharge time as a variable t, and calculating a time average value t_ave of a plurality of groups of variables t.
The specific calculation formula is as follows:
for example: t1=1, t2=2, t3=3, t4=4.
A32, marking the historical heating value as a variable Q, and calculating the heating value average value Q_ave of a plurality of groups of variables Q.
The specific calculation formula is as follows: q_ave=1/n (q1+q2+q3+, +qn), (n > 0) for example: q1=1, q2=3, q3=5, q4=7.
A33, calculating standard deviation t_s of a plurality of groups of variables t based on the time average value t_ave.
The calculation formula of the standard deviation t_s is as follows:
when t_ave is 2.5, t1=1, t2=2, t3=3, t4=4, then:
standard deviation of
A34, calculating standard deviation Q_s of a plurality of groups of variables Q based on the heating value average value Q_ave.
The calculation formula of the standard deviation Q_s is:
a35, calculating covariance of the variable Q and the variable t based on the standard deviation t_s and the standard deviation Q_s.
The covariance of the variable Q and the variable t (Cov (t, Q)) is calculated as:
a36, calculating a correlation coefficient r of the variable t and the variable Q based on covariance.
The correlation coefficient r is used to represent the relationship between the heat generation amount Q and the charging time t.
The calculation formula of the correlation coefficient r is as follows:
wherein the variance of q= (q_s) 2 Variance of t= (t_s) 2 Then
The calculation formula of the correlation coefficient r is as follows:
a37, calculating a parameter a, a parameter b and a parameter c based on the time average value t_ave, the heating value average value Q_ave, the standard deviation t_s, the standard deviation Q_s, the covariance and the correlation coefficient r.
Specifically, the values of the parameter a, the parameter b, and the parameter c are calculated by the least square method from the calculated time average value t_ave, the calorific value average value q_ave, the standard deviation t_s, the standard deviation q_s, the covariance, and the correlation coefficient r.
A4, determining a heating model based on the parameter a, the parameter b and the parameter c.
For example: when the parameters a=0.859, b= -1.393, c=7.875 are calculated in step A3, the heating model is: q=0.859 t 2 -1.393t+7.875
S4, acquiring actual parameter information associated with the outdoor power supply in real time. The parameter information includes an actual voltage value, an actual resistance value, an actual current value, and test time information.
S5, calculating actual heating information related to the outdoor power supply based on the actual parameter information, wherein the actual heating information comprises actual heating value and actual test time;
in the process of charging and discharging test of the outdoor power supply, the actual parameter information of the outdoor power supply is obtained in real time, so that the actual heating value of the outdoor power supply is calculated in real time, and a mapping relation is established between the actual heating value and the corresponding test time.
Specifically, the actual test time is calculated from the time node at which the test is started, for example: the charge and discharge test is started from the standard time of 10:00:00, and the heating value Q1 of the outdoor power supply is obtained at the moment of 10:00:01, so that the corresponding test time is 1 second and is approximately equal to 0.0167min.
Also for example: the charge and discharge test is to start the test from the standard time of 10:00:00, and obtain the heating value Q2 of the outdoor power supply at the moment of 10:01:00, and the corresponding test time is 1min.
The mapping relationship between the actual heating value and the actual test time of the outdoor power source can be exemplified by the following table:
| actual test time (min) | 0 | 1 | 2 | 3 |
| Actual heating value (Tile) | 0 | 0.01 | 0.01 | 0.02 |
S6, comparing the heating value in the actual heating information with the heating value associated with the test time information in the heating model.
Specifically, the actual test time in the actual heating information is substituted into the heating model, the heating value associated with the test time is calculated, and then the actual heating value in the actual heating information is compared with the heating value calculated by the heating model.
And S7, when the heat quantity in the actual heat generation information is higher than the heat quantity associated with the test time information in the heat generation model, reducing the input current of the outdoor power supply or reducing the output current of the outdoor power supply and sending out alarm information.
Specifically, when it is determined that the actual heat generation amount is higher than the heat generation amount calculated through the heat generation model, the input power source or the input power source of the outdoor power source is reduced, so that the heat generation amount continuously generated by the outdoor power source is reduced, and meanwhile, an alarm is sent out to remind a worker of timely checking whether the outdoor power source expands or not.
When the actual heating value is determined to be lower than the heating value calculated by the heating model, the step S2 is directly skipped to continuously monitor whether the outdoor power supply generates heat in the charge-discharge test process, the operation of reducing the input current or the output current is not performed, and an alarm is not sent out.
In some possible embodiments, the actual heat generation information is marked as an abnormal data packet when the heat generation amount in the actual heat generation information is higher than the heat generation amount associated with the test time information in the heat generation model. In the process of establishing the heating model in the next round, abnormal heating data can be distinguished from normal heating data when historical parameters are searched, and meanwhile, workers can conveniently provide relevant data for detection and analysis of an outdoor power supply.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
The embodiment of the application also discloses an outdoor power supply charge-discharge control system, which corresponds to the outdoor power supply charge-discharge control method in the embodiment one by one.
