Detailed description of the invention
Below in conjunction with the accompanying drawings and example, this utility model is described further.
In the present embodiment, as shown in Figure 1 and Figure 2, this on-keyboard coding lock system is from hardware
Cipher input equipment and two parts of password identification equipment can be divided into.
Cipher input equipment is alternatively referred to as wireless key, this wireless key has button and (also may be used
With other input modules such as touch screens), input equipment generating laser, low-power consumption micro single-chip microcomputer
(the present embodiment uses STM32F407 main control chip) and input equipment wireless communication module.
When user's hand-hold wireless key pushes button, the internal Single-chip Controlling input equipment of wireless key without
Line communication module sends a signal to password identification equipment, and user can pass through wireless key subsequently
Upper input equipment generating laser carries out Password Input on password identification equipment.
Password identification equipment is this system master controller, and its performance is directly connected to a whole set of function series
System realizes.After wireless key push button signalling is identified equipment reception, identification equipment is opened identification and is set
Standby laser coordinate system, produces 3 hot spots in the plane, forms a plane right-angle coordinate,
Wireless key need to be used when user unlocks to input password in this coordinate system.System is opened laser and is sat
After mark system, can enter solution latching mode, hereafter (wireless key is in location for the every moving cursor of user
The hot spot of projection in coordinate system), the input of a password value is represented by wireless push next time.With
After family inputs each password value, the image capture module camera collection on identification equipment comprises sharp
Light right angle location coordinate and the image of vernier, and send it to microprocessor.Micro-process
Device uses image recognition algorithm process view data and analyze, the image after processing
Data show on display module LCD display, finally according to right angle location coordinate and vernier
Relative position obtain a password value.Repeat single password value input process and can complete multiple
Password value inputs.
For strengthening system safety, preventing from illegally opening and cracking, this utility model is provided with
Multiple-enciphered protection system.
1. wireless key protection system.After wireless key needs and identifies device talk success, know
Other equipment just opens location coordinate can enter releasing process.In order to prevent wireless key to be stolen
Replicating, this utility model uses the mode of password poll to be encrypted radio communication, will identify
Equipment is bound with wireless key, and identification equipment only receives matched wireless key
Spoon signal just can enter solution latching mode.Password polling mode is as follows: set wireless key and identification
The password string that in standby microprocessor memory space, writing complex degree is high, wireless during each wireless telecommunications
Key sends the value in a password string, and microprocessor compares inner cipher string, if this value and nothing
The value that line communication receives is identical, and microprocessor returns a pass signal, nothing to wireless key
Line key and microprocessor internal count value all add 1, and communication next time is by under in password comparison string
One value.Can effectively protect the safety of wireless key in this way, prevent other people from adopting
With technological means monitoring wireless signal, reach the purpose of imitated wireless key.
2. Password Input protection.In order to protect cipher safety to prevent other people from stealing, first this is
Password Input number of times is limited by system, if input error password number of times reaches the upper limit continuously,
System will be locked, be simultaneously emitted by alarm signal, remind user cipher hidden danger occur safely.Its
Secondary, employ the self-defined setting of keyboard, what the identification of password value actually identified is that vernier is relative
In the position of right angle location coordinate, change each password value position therewith in location coordinate,
Can reach the effect upset by code keypad, so can prevent other people from using monitoring device for shooting
Family Password Input process illegally obtains system password.
Additionally, the design has reserved developer's protection interface, this interface is that a serial communication connects
Mouthful, limit or the system urgent need that goes wrong is opened when user cipher input error number of times exceedes system
During equipment, this serial line interface can be used to carry out checking and to unblank.This interface security grade is high, if
Authentication error, direct locked built-in system, system loses all functions.If needing system recovery to make
With, it is necessary to contact developer again updates software for hardware, effectively protects whole system peace
Quan Xing.
Fig. 3 show native system flow chart, first module initialization each to system when equipment works,
Gather ambient light subsequently carry out light intensity calibration and wait, if now user presses wireless key, be
System enters and solves latching mode.Entering after solving latching mode, it is raw that password identification equipment opens generating laser
Become laser coordinate system to input password value for user, each coordinate position is positioned simultaneously, obtain
Coordinate system is relative to image origin coordinate.A password is represented when user presses wireless key
Input, now camera collection Password Input image, by obtaining a password after algorithm process
Value, if Password Input completes, judges that password is the most correct, otherwise continues with password.When close
System misregistration number of times during code input error, if input error number of times is less than three times continuously,
Can re-enter password, otherwise system is locked.System unlocking signal when Password Input is correct,
And can be by carrying out password value change.
The present embodiment uses the mode of image recognition technology combining wireless key to be unlocked.First,
Wireless key heavily protects as first, and only unique wireless key just can be recognized by the system, from
And enter solution latching mode.Secondly, utilize the feature that keypad lock number of password is abundant, use image to know
Other technology fictionalizes keyboard in plane, user by wireless key at planar movement laser spot,
This plane picture information of camera collection, microprocessor is known by the way of binding positions password value
Judge that password is the most correct the most afterwards, thus reach unlocking pin effect.
Above-mentioned vernier is not limited to be formed by the hot spot of input equipment laser transmitter projects, also
Other unlocking manners such as gesture can be used to obtain.
This utility model parts are few, simple in construction, unlock in conjunction with image and the advantage of keyboard unblock
Make stable and reliable in work, adapt to the Password Input under various environment, solve physical keyboard close
The problem that code lock is easily stolen and environment limits.It addition, use image to unlock improve equipment peace
Quan Xing, it is simple to the characteristic of upgrading also makes unlocking manner have more selection (such as gesture unblock etc.).
