Abstract
The invention discloses a system and a method for locking and unlocking a keyboard. The system comprises a button scanning device, an information determining device, a keyboard state changing device and a keyboard state detection device. The method comprises the following steps of: scanning button information from a matrix by using the button scanning device, and if determining that the button information is from specific buttons by using the information determining device, sending determined information to the keyboard state changing device, so that the keyboard state changing device locks or unlocks the keyboard; and if determining that the button information is not from the specific buttons, starting the keyboard state detection device to detect whether the keyboard is in the locking state or not, and judging whether a key code is sent to a host or not according to a detection result. In the method, the keyboard is locked or unlocked by setting the at least two specific buttons to prevent other people from stealing information by the misoperation of the keyboard or malicious operation.
Description
Technical field
The present invention relates to a kind of system and method for keyboard being realized locking and release.
Background technology
Along with constantly popularizing of computer technology, the peripheral hardware keyboard of computing machine also is widely used in various occasions, but because the operation of fortuitous event or malicious operation mouse-keyboard etc. can cause bad consequence, for example, in routine duties, the user need carry out the sassafras examination to keyboard, direct control causes maloperation easily and influences the operation of present procedure, if pull out keyboard plug, then use inconvenient, or after the main frame unlatching, the machine main cause be busy leave the position after, some privacies on the main frame or important content are seen after may being opened by other people malicious operation, are caused harmful effect, also might cause the deleted or modification of some data message in addition, the keyboard that perhaps is used for Medical Devices at some, other people maloperation or malicious operation cause the Medical Devices fault, when serious, can cause the generation of malpractice, this just exists certain inconvenience.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, a kind of system and method for keyboard being realized locking and release is provided, this system and method is realized locking or release to keyboard by at least two specific buttons setting, prevents that maloperation influences the operation or the malicious operation steal information of program to main frame by keyboard for other people.
The technical solution adopted in the present invention is: the invention provides and a kind of keyboard is realized the system of locking and release, realize locking and release to keyboard by at least two specific buttons setting, this system comprises:
The key scan device is used to scan the key information from all buttons on the keyboard;
The information discriminating gear is used to judge that whether the key information that scans is from specific button;
Keyboard state change device is used to receive the judgement information that described information discriminating gear is sent, and carries out locking or release then;
The keyboard state pick-up unit is used to receive the judgement information that described information discriminating gear is sent, and the detection keyboard is in the lock state still released state;
Described key scan device scanning is from the key information of matrix, described information discriminating gear is if judge that this key information comes from specific button, then judgement information is sent to keyboard state change device, described keyboard state change device is carried out locking or release to keyboard; If judge that this key information is not to come from specific button, then start described keyboard state pick-up unit detection keyboard and whether be in the lock state,, then do not send key to main frame if be in the lock state, if keyboard is a released state, then transmission and the corresponding key of key information are to main frame.
The invention provides and a kind of keyboard is realized the method for locking and release, realize may further comprise the steps locking and release to keyboard by at least two specific buttons setting:
(1) scanning of key scan device is from the key information of all buttons on the keyboard;
(2) the information discriminating gear judges that whether the described key information scan is the key information from above-mentioned specific keys, if not the key information of above-mentioned specific keys, then transfer step (3) to, if the key information of above-mentioned specific keys is then carried out locking or release to keyboard;
(3) the keyboard state pick-up unit detects whether keyboard is lock-out state, if keyboard is a lock-out state, does not then send key to main frame, if keyboard is a released state, then transmission and the corresponding key of key information are to main frame.
The invention has the beneficial effects as follows: the system and method for locking provided by the invention and release, only need simple code just can realize only keyboard being realized locking or release by specific button, prevent other people to influence the operation or the malicious operation steal information of program by the maloperation of keyboard main frame, operating process is convenient, simple.
Description of drawings
Fig. 1 is a functional block diagram of the present invention;
Fig. 2 is the process flow diagram of locking of the present invention and release keyboard.
Embodiment
As shown in Figure 1, functional block diagram for system of the present invention, comprise key scan device 1, information discriminating gear 2, keyboard state change device 3, keyboard state pick-up unit 4, wherein, described information discriminating gear 2 is if judge that this key information comes from specific button, then judgement information is sent to described keyboard state change device 3,3 pairs of keyboards of described keyboard state change device are carried out locking or release; If judge that this key information is not to come from specific button, then start described keyboard state pick-up unit 4 detection keyboards and whether be in the lock state, judge whether to send key to main frame according to testing result again.
The workflow of the method for the locking and unlocking keyboard provided by the invention as shown in Figure 2: keyboard and main frame are connected and initialization by interface, step 10; In the course of work, the described key scan device scanning of system specifically, is the matrix data of scanning button below matrix circuit from the information of all buttons on the keyboard, step 20; Then the key information that scans is passed to described information discriminating gear, described information discriminating gear judges whether the key information that scans is specific button, step 30; If not specific key information, then information is passed to described keyboard state pick-up unit, step 40; Whether described keyboard state pick-up unit detects keyboard and locks, if lock, does not then send key, if be in released state, then sends corresponding key to main frame, step 50; If specific key information then passes to described keyboard state change device to information, described keyboard state change device is changed the state of keyboard, if keyboard is in the lock state, then unlocks, if be in released state, then carries out lock step 60.
