Be described in further detail below in conjunction with accompanying drawing illustrated embodiment.
The present invention proposes a kind of remote-control unlocking method, based on the wireless remote-control lock system comprising remote-control key and lock body.As shown in Figure 4, described method comprises the steps:
When setting the password word string for unblanking, M position password word string is stored in lock body, M > 2, randomly draws N position condition code simultaneously and is stored in remote-control key, 1 < N < M in this password word string;
When unblanking with remote-control key, described remote-control key performs following steps,
B. flow process 21 as shown in Figure 4, detects the word string whether having input;
C. flow process 21 as shown in Figure 4, if there is the word string of input, performs steps d, namely performs flow process 22;
If there is no the word string inputted, return step b;
D. flow process 22 as shown in Figure 4, detects in described word string whether there is all condition codes;
If there is all condition codes in the word string of input, perform step e, namely perform flow process 23 as shown in Figure 4;
If there is not all condition codes in the word string of input, perform step f;

C. whether identical with password word string flow process 12 as shown in Figure 4, detect described word string to be verified;
If described word string to be verified is identical with password word string, performs step D, namely perform flow process 13 as shown in Figure 4;
If described word string to be verified is not identical with password word string, perform step e;
D. unlocking action is completed;
E. return steps A, namely return flow process 11 as shown in Figure 4.
Described method all have employed verification mode for remote-control key and lock body, improves security of system by double verification.Described remote-control key adopts the mode of condition code checking instead of all password authentifications, prevents remote-control key once be stolen and cause password stolen in the lump.The quantity of described condition code is more, and the word string of the non-password word string shielded by remote-control key is more, but is more easily known complete password by other people faster by the mode of the key that snatches password.Described condition code quantity is fewer, and the security of system is lower.Therefore the condition code choosing proper quantity is needed.Following instance of the present invention with " 12345678 " for password word string, with " 3 ", " 6 " and " 8 " for condition code, namely above-mentioned M=8, N=3.When input word string is " 35918067 ", can be sent by remote-control key because this group word string has whole condition code, but not by the checking of lock body.When input word string is " 35918027 ", because this group word string only has two condition codes, instead of whole condition code, thus this group word string will be shielded by remote-control key.
Said method is from remote-control key and lock body data handling procedure statement separately, and the general data that the dotted portion in Fig. 4 and in Fig. 5 to Fig. 7 represents between remote-control key and lock body flows to.
For improving the shield effectiveness of remote-control key to bad password further, when setting the password word string for unblanking, M position password word string is stored in lock body, in this password word string, randomly draw N position condition code to be stored in remote-control key simultaneously, and the position in each for condition code comfortable cipher word string is also stored in remote-control key as condition code positional information.As shown in Figure 5, on process base shown in Fig. 4, increase the flow process of condition code positional information method of discrimination.
The steps d that so described remote-control key performs and e also comprise as follows step by step,
D1. flow process 221 as shown in Figure 5, stores described word string;
D2. flow process 222 as shown in Figure 5, detects in described word string whether there is the character code identical with all condition codes;
If there is the character code identical with all condition codes in described word string, perform steps d 3, namely perform flow process 223 as shown in Figure 5;
If there is not the character code identical with all condition codes in described word string, perform step f, namely flow process 21 as shown in Figure 5;
D3. flow process 223 as shown in Figure 5, detects the position of character code identical with all condition codes in described word string in this word string whether identical with described condition code positional information;
If identical, perform step e1 to e2, namely perform flow process 231 and 232 as shown in Figure 5;
If not identical, perform step f, namely flow process 21 as shown in Figure 5;
E1. flow process 231 as shown in Figure 5, sends the mode of described word string radio communication;
E2. flow process 232 as shown in Figure 5, deletes the described word string that d1 step by step stores, returns step b, namely return flow process 21 as shown in Figure 5.
Said method improves security of system further by checking condition code position.Example described above, the condition code " 3 " of password word string " 12345678 ", the condition code positional information of " 6 " and " 8 " are " 368 ".For when input word string is " 35918067 ", although this group word string has whole condition code, positional information of this group word string is " 175 ", different from condition code positional information, thus this group word string will be shielded by remote-control key.
In order to improve the security of lock body checking further, code error counting variable w=0 is set in lock body, the correct counting variable y=0 of password; And maximum permission code error number constant P is set, minimum input password positive exact figures constant Q, and standby dormancy time constant Z.As shown in Figure 6, the process base shown in Fig. 5 adds bad password to transfinite the flow process of method of discrimination, and namely flow process shown in Fig. 6 adds condition code positional information discrimination function and bad password on process base shown in Fig. 4 simultaneously transfinites discrimination function.Obviously, the flow process of the method for discrimination that also bad password can be transfinited only is added in the basic flow process shown in Fig. 4, thus in flow process basic shown in Fig. 4, only realizes bad password to transfinite discrimination function.
The step C that described lock body performs comprises as follows step by step,
C1. whether identical with password word string flow process 121 as shown in Figure 6, detect described word string to be verified;

If described word string to be verified is not identical with password word string, as shown in Figure 6 flow process 1271, the correct counting variable y of password resets, and returns step C4;
C7. flow process 128 as shown in Figure 6, the correct counting variable y=y+1 of password; ; Then following judgement is completed by flow process 129 as shown in Figure 6,
If password correct counting variable y currency equals Q, perform step D, i.e. flow process 13 as shown in Figure 6;
If password correct counting variable y currency is not equal to Q, return step C4.
The detecting of described method is by the situation of repeatedly input error password, the situation of namely different from password word string word strings to be verified, and force lock body to wait for that the mode of Z minute guarantees security of system when this situation occurs, described wait refers to the program stopping every operation and operation for Z minute, especially stops the step receiving word string to be verified.Described maximum permission code error number P can select five times; Described wait can be selected to be set to 30 minutes for Z minute.Further, system, after generation repeatedly receives the situation of the word string to be verified of non-password word string, must make System recover normal by the mode inputting proper password word string continuously.The positive exact figures Q of described minimum input password can be chosen as twice.
The present invention also also add the method for Modify password word string on described remote-control unlocking method basis, stored in Modify password request code in described remote-control key and lock body; Modify password input degree variables r=0 is set in described lock body, and the Modify password input number of times constant R of setting.As shown in Figure 7, process base shown in Fig. 6 adds bad password to transfinite the flow process of method of discrimination, namely flow process shown in Fig. 7 adds condition code positional information discrimination function on process base shown in Fig. 4 simultaneously, bad password transfinites discrimination function and Modify password word string function.Obviously, process base shown in Fig. 4 also can increase condition code positional information discrimination function, bad password transfinites discrimination function and any one function in Modify password word string function or any two kinds of functions.
