the condition that no battery is arranged at the battery cell of the battery replacing cabinet is as follows:
S n > 0 and B n 0 and M n 0 and P n ≤P Threshold value N is the serial number of the battery cell of the battery changing cabinet, and if the conditions are met, X is equal to X-1;
in the service state, the number of the batteries in the power exchange cabinet is still monitored, and the method comprises the following steps:
s1: before the battery replacement service is started, the number of batteries of the battery grid is calculated;
s2: an operator opens an empty cell or a full cell;
s3: judging whether the battery is put in or taken out by detecting the state information of the battery cell;
s4: and after the battery replacement is finished, the number of the batteries in the battery grid is calculated.
5. The method for preventing battery theft of a battery replacement cabinet based on the Internet of things as claimed in claim 4, wherein: suppose the time stamp of the battery number of the battery grid is t before the service of the power change cabinet is started 1 (ii) a The time stamp of opening an empty grid or a full grid is t 2 (ii) a The battery put-in or take-out time stamp is t 3 (ii) a The state judgment and detection timestamp of the battery grid door is t 4 (ii) a The detection time stamp of the opening information of the battery grid opening is t 5 (ii) a After the battery replacement service is finished, the timestamp for calculating the number of the grid batteries is t 6 ；
Obtaining the information acquisition time sequence of the whole battery replacement process as
C＝{t 1 ，t 2 ，t 3 ，t 4 ，t 5 ，t 6 }；
Wherein:
t 1 the trigger condition is S Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power ＞0；
t 2 The trigger condition is (S) Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power > 0) and ((S) n 0 and B n 0 and M n 0 and P n ＞P Threshold value ) Or (S) n 0 and B n Greater than 0 and 0 < M n ≤M Threshold value And P is n ＞P Threshold value ))；
t 3 Triggering conditions are as follows: put into a battery to be (S) Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power > 0) and (S) n 0 and B n Greater than 0 and 0 < M n ≤M Threshold value And P is n ＞P Threshold value ) Taken out ofThe battery is (S) Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power > 0) and (S) n 0 and B n 0 and M n 0 and P n ＞P Threshold value )；
t 4 Triggering conditions are as follows: put into a battery to be (S) Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power > 0) and (S) n > 0 and B n Greater than 0 and 0 < M n ≤M Threshold value And P is n ＞P Threshold value ) The battery is taken out as (S) Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power > 0) and (S) n > 0 and B n 0 and M n Is equal to 0 and P n ＞P Threshold value )；
t 5 Triggering conditions are as follows: put into a battery to be (S) Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power > 0) and (S) n > 0 and B n Greater than 0 and 0 < M n ≤M Threshold value And P is n ≤P Threshold value ) The battery is taken out as (S) Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power > 0) and (S) n > 0 and B n 0 and M n 0 and P n ≤P Threshold value )；
t 6 The trigger condition is(s) Drawing (A) > 0 and G Electric power ≤G Threshold value And X Electric power > 0) and the order has been generated;
