Abstract
The invention discloses a method for locking a television regularly. In this invention, it makes a television can be locked at regular time through the controlling by the software program of a circuit chip microcontroller in the television to make TV can be used in a specific period of time, other than the time except the correct password can be input. This function can effectively control the unrestrained children watching television.
Description
Technical field
The present invention relates to a kind of new television set function, in particular, is to design a kind of method that viewing time can be realized timed locking machine that limits.
Background technology
At present, television set has become the indispensable article of each family.And, make television set that more and more important meaning be arranged in people's life along with increasing day by day of TV functions and becoming increasingly abundant of TV programme.But the TV functions that becomes increasingly abundant also can make the child of some the self-control differences TV of wallowing in, and has influence on study and physically and mentally healthy.Functions of child lock in the television set can only lock certain channel at present, can not reach the uncontrolled requirement of seeing TV of control child.And the enforceable child of forbidding sees that TV also makes it produce antagonistic psychology easily, is difficult for it and grows up healthy and sound.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, improves system for TV set mechanism is set, and a kind of method of timed locking machine for TV set is provided.
The method of timed locking machine for TV set of the present invention, the software program control by the singlechip chip in the TV set circuit comprises the steps:
1. carry out the timed locking machine Function detection after the start, judge whether the automatic lock machine function of television set starts, if not this function of tool or not startup, the television set normal condition is play; If start, carry out next step 2;
2. carry out time clock feature then and detect, judge whether the television set time clock feature starts, if do not have this function or not startup, then the television set normal condition is play, if this function starts, carries out next step 3;
3. time for reading parameter A from register (EEPROM);
4. bring in constant renewal in the current time, whether judge the current time, if normal play early than A then still if parameter current is later than or equals A then the locking television machine, is carried out next step 5 early than parameter A;
5. detect the key information input,, then carry out step 6 if do not detect key information; If detect key information, then carry out step 8;
6. time for reading B parameter from register (EEPROM);
7. whether detect the current time early than time parameter B, as early than, then keep lock-out state, constantly upgrade current time and B parameter comparison, be later than or equal B, if detect that the current time is later than or equate with B parameter up to the current time, then television set unlocks, and gets back to the normal play state;
8. from register (EEPROM), read parameter c;
9. judge that whether the key value receive conforms to parameter c in the register (EEPROM), if do not conform to, just carry out step 5; Conform to parameter c if detect key value, the function that then unlocks finally enters the normal play state.
Parameter of the present invention is A altogether, B, three of c.These three parameters are stored in the register (EEPROM), and the default setting when also starting shooting can manually be set before the 3rd step by the user.A lock machine time that to be the user be provided with by TV menu wherein, judge that the current time is later than or when equaling A, television set automatically locks; B is the release time that the user is provided with, when the judgement current time is later than or equals B, and the television set automatic unlocking; C is the 4 figure place passwords that the user inputs, and when judging that the input key assignments equals c, the television set lock-out state is removed.
Parameter A of the present invention and B parameter are the time parameter of 0 point-24, minute being minimum effective unit; Parameter c is 4 sequential numerals among the numerical key 0-9.
Running environment is the C51 single-chip microcomputer, and programming language is the C language.
Use method user of the present invention manually to be set the locking and the release time of television set by the option that provides in the TV menu.After the TV locking, tv state is: any channel all shows blank screen, and volume is a mute state, and except that inputing the operation and power-off operation of 4 bit digital passwords by correct order, television set does not respond other key value.
For guaranteeing enforcement of the present invention, this function must be carried out under the environment that television set is not cut off the electricity supply.
The invention has the beneficial effects as follows: the controlled function of expansion television set, according to the locking and unlocking time of user's setting, central processing unit (cpu) begins clock is monitored, and when the time met certain particular parameter value, central processing unit (cpu) carried out lock machine or unlocking operation.The particularly setting of cryptographic parameter is easier to the user and controls TV functions.The present invention rationally adopts software programming under the situation that does not change the hardware system setting, make it be easier to realize, and effectively guarantee the productivity of television set, stability, reliable in quality.
Description of drawings
Fig. 1 is a process principle figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
1. carry out the timed locking machine Function detection after the start, judge whether the automatic lock machine function of television set starts, if not this function of tool or not startup, the television set normal condition is play; If start, carry out next step 2;
2. carry out time clock feature then and detect, judge whether the television set time clock feature starts, if do not have this function or not startup, then the television set normal condition is play, if this function starts, carries out next step 3;
3. television set reads parameter A from memory (EEPROM), and parameter A is stored in the register (EEPROM), and the default setting when also starting shooting can manually be set before the 3rd step by the user;
4. bring in constant renewal in the current time, judge that whether the current time is early than parameter A, if normal play early than A then still, if parameter current is later than or equals A then the locking television machine, at this moment, central processor CPU sends instructions respectively to picture processing chip and sound process chip, and these two chips are received the instruction back and just carried out blank screen respectively, with quiet operation, realized the locking of television set.Carry out next step 5 then;
5. in the process that lock function is carried out, whether TV detects the key information input, if do not detect key information, then carry out step 6; If detect key information, then carry out step 8;
6. time for reading B parameter from register (EEPROM), B parameter is stored in the register (EEPROM), and the default setting when also starting shooting can manually be set before the 3rd step by the user;
7. whether detect the current time early than time parameter B, as early than, then keep lock-out state, constantly upgrade current time and B parameter comparison, be later than or equal B, if detect that the current time is later than or equate with B parameter up to the current time, then television set unlocks, and gets back to the normal play state;
8. read parameter c from register (EEPROM), parameter c is stored in the register (EEPROM), and the default setting when also starting shooting can manually be set before the 3rd step by the user;
9. judge that whether the key value receive conforms to parameter c in the register (EEPROM), if do not conform to, just carry out step 5; Conform to parameter c if detect key value, the function that then unlocks finally enters the normal play state.
