Abstract

The method comprises: opening password theft-protection function; deciding if the user's operation is a counting command; if yes, then starting up the counter to start counting; otherwise, the electric appliance runs normally; deciding the cumulative number reaches a preset number; if yes, then inputting the password to start the counter 2; deciding if the password is correct; if yes, then resetting the counter 1; otherwise, entering the next step; deciding the times of inputting the password is over the preset times; if yes, then entering a limited state. The invention also reveals a electric appliance theft-protection system comprising a CPU, a memory and a counter.

Description

A kind of electric appliance anti-theft method

[technical field]

The present invention relates to electrical equipment, relate in particular to a kind of theft preventing method that is used for electrical equipment.

[background technology]

Along with the raising of people's living standard, use high-grade electrical equipment to become universal phenomenon.Yet the high-grade electrical equipment price on the market is very high now, but does not design anti-theft feature mostly; What have has an anti-theft feature, but needs to increase hardware cost, and easily is removed, and anti-theft feature is unreliable; Therefore this uses high-grade electrical equipment to bring a lot of unsafe factors to people, provides a kind of method that can improve or eradicate the insecurity of using high-grade electrical equipment necessary.

[summary of the invention]

It is high and do not increase the electric appliance anti-theft method of cost to the invention provides a kind of reliability.

In order to solve above technical matters, the invention provides a kind of electric appliance anti-theft method, comprise step:

A), open the cipher anti theft function;

B), judge whether user operation is the counting instruction, if, enabling counting device 1 and begin counting then; Otherwise electrical equipment normally moves;

C), judge whether the stored counts value reaches predetermined number: if then input password enabling counting simultaneously device 2 and judge whether the password of being inputed is identical with setting code; If then counter 1 zero clearing and electrical equipment normally move; Otherwise, enter step d);

D), judge whether the number of times of input password surpasses pre-determined number, if then enter the use constrained state.

Above-described electric appliance anti-theft method does not continue counting in the described step c) when the stored counts value reaches predetermined number and electrical equipment normally moves.

Above-described electric appliance anti-theft method is returned the input password in the step c) when input password number of times does not surpass predetermined times in the described step d).

Also comprise after the above-described electric appliance anti-theft method, described step a) password and storage are set.

Also comprise after the above-described electric appliance anti-theft method, described step b) counting instruction and storage are set.

Above-described electric appliance anti-theft method, the counting instruction in the described step b) according to operation setting commonly used, comprises the operation in start and other any normal course of operation by the user; Predetermined number in the described step c) can be set by the user; The pre-determined number of input password can be set by the user in the described step d).

In addition, the present invention also provides a kind of electric appliance anti-theft system, comprise CPU, storer, counter, described CPU is used for execution of program instructions and control total system operate as normal, described storer is used for storing password, counting instruction and count value, and described counter is used for the number of times that recording user operation is inputed password for the number of times and the user of counting instruction.

Electric appliance anti-theft method and system of the present invention are not needing to increase on the basis of hardware cost, only realize anti-theft feature by software, and cost is low, reliability height, high safety.

[description of drawings]

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

Fig. 1 is the process flow diagram of electric appliance anti-theft method and system embodiment 1 of the present invention.

[embodiment]

The invention provides a kind of electric appliance anti-theft method and system, its course of work is: after the user buys electrical equipment, open the cipher anti theft function, revise the new password of menu setting by the client, as owner's identification code; In user's use, electric system by gather operational example commonly used as start, change platform, regulate countings instruction enabling counting device 1 such as volume and begin to count, the stored count value deposits storer in, when accumulative total numerical value reaches present count, electrical equipment requires the user to import owner's identification code, if input is correct in the input password number of times that limits, then electrical equipment normally moves, the unison counter zero clearing; If input password mistake still when reaching the input password number of times of qualification, electrical equipment enters the use constrained state automatically so, no longer accepts any operation, has only former factory engineering teacher can recover normal condition.So electrical equipment can not continue normal use after stolen; Utilize this password burglary-preventing method and system to reduce so that eliminate the generation of the robbed or burgled phenomenon of electrical equipment.

In addition, in the present invention, institute's counting number instruction, predetermined number and password input number of times can be set by user oneself.

In electric appliance anti-theft method and system embodiment 1 of the present invention shown in Figure 1, a kind of electric appliance anti-theft method is provided, may further comprise the steps:

101. open the cipher anti theft function;

102. password and storage are set;

103. whether judge user operation is the counting instruction, if, then enabling counting device 1 and execution in step 104; Otherwise, execution in step 110;

104. counter 1 counting;

Whether reach predetermined number 105. judge accumulative total numerical value, if then execution in step 106; Otherwise, return step 104 execution in step 110 simultaneously;

106. the user inputs password enabling counting simultaneously device 2;

107. counter 2 countings;

108. whether the password of judging input with that password is set is identical, if execution in step 109 execution in step 110 simultaneously then, otherwise execution in step 111;

Whether surpass the input password number of times that limits 111. judge the number of times of input password, if, execution in step 112; Otherwise, return step 107;

112. use constrained state.

In addition, in the present embodiment, a kind of electric appliance anti-theft system also is provided, comprise CPU, storer, counter 1 sum counter 2, described CPU is used for execution of program instructions and control total system operate as normal, described storer is used for the count value etc. of count value sum counter 2 of stored count instruction, user identification code, counter 1, described counter 1 is used for recording user performed counting instruction number of times in once making the electrical appliance process, and described counter 2 is used for the number of times of recording user input password.

In addition, in the present embodiment, described electrical equipment can be televisor and other high-grade electrical equipment; Described reservation number can be 50, and the pre-determined number that described user inputs password can be 3.

Electric appliance anti-theft method and system of the present invention are not needing to increase on the basis of hardware cost, only realize anti-theft feature by software, and cost is low, reliability height, high safety; Can prevent effectively that high-grade electrical equipment is stolen.
