Accompanying drawing explanation
Fig. 1 is process flow diagram of the present invention;
Fig. 2 is schematic diagram of the present invention.
Embodiment
Fig. 1 is process flow diagram of the present invention.Realization of the present invention need to be through several steps once.
Step 1: in locking system, arrange 2 bluetooth modules simultaneously, 2 bluetooth modules as required, can freely select one for data transmission, another obtains for only carrying out signal intensity, in the situation that part is special, even can freely selectes 2 bluetooth modules and carry out data transmission.Two bluetooth modules are all powered by the electric power system of locking system, can be batteries, can be also the modes of external power supply.
The object that has certain electromagnetic wave obstructing capacity by layout in the middle of step 2:2 bluetooth module carries out signal to be stopped.If 2 bluetooth modules of simple layout, and the distance of 2 bluetooth modules is closer, can cause signal intensity between 2 to distinguish not obvious, then consider upper error, may cause the result that draws and actual result inconsistent.So carrying out signal, the object that needs layout to have certain electromagnetic wave obstructing capacity between 2 bluetooth modules stops.The object of this electromagnetic wave obstructing capacity, can be that producer oneself arranges, then together with locking system, installs, and also can producer not arrange, directly adopt natural object to exercise identical function, that is exactly door.Domestic antitheft door generally adopts iron and steel manufacture, itself has larger signal obstructing capacity.
Step 3:2 bluetooth module obtains the signal intensity of handheld device simultaneously.When user comes door around, in the time of need to unblanking, 2 bluetooth modules of locking system can obtain the signal intensity of this handheld device simultaneously, then each obtains the signal strength values of oneself, as preferably, what some scheme adopted is handheld device mode initiatively, so both can adopt mobile phone to search for the mode of the signal intensity of 2 bluetooth modules simultaneously, and obtains 2 signal strength values that bluetooth module is concrete.
Step 4: if the signal intensity that bluetooth module outdoors obtains surpasses the signal intensity that the bluetooth module in door obtains, carry out the flow process of unblanking, if the signal intensity that bluetooth module outdoors obtains is less than the signal intensity that the bluetooth module in door obtains, do not carry out the flow process of unblanking.In this step process, do not need signal intensity and distance to carry out a correspondence, if 2 bluetooth modules have all got the signal intensity of handheld device, automatically can obtain the value of a signal intensity, then according to the value of two signal intensities, distinguish which signal strong, a little less than which signal, if the signal intensity of the handheld device that the bluetooth module of outer side of door gets is better than the signal intensity of the handheld device that the bluetooth module of an inner side obtains, can obtain a result, handheld device is in the outside of door, next the process that need to carry out of can unblanking, vice versa.
It should be noted that, what some scheme may adopt is handheld device mode initiatively, it is the not externally search of bluetooth module of locking system itself, just wait until that handheld device searches for it, in this sample step, a little a little change, that is exactly the signal intensity that handheld device is carried out 2 bluetooth modules of active searching, by obtaining the signal strength values of 2 bluetooth modules, if the bluetooth module signal intensity of the bluetooth module signal intensity ratio door of outer side of door inner side is strong, the work of unblanking, if a little less than the bluetooth module signal intensity of the bluetooth module signal intensity ratio door of outer side of door inner side, judge that handheld device is now positioned at the inner side of door, the action of not unblanking.
In above-mentioned all mensuration of carrying out Bluetooth signal intensity level, because may existing the variation of various external environment conditions, signal intensity presents a small amount of fluctuation, so general, adopt the mode of averaging of repeatedly measuring.
Fig. 2 is schematic diagram of the present invention.In Fig. 2, be furnished with and intercept object 31, intercept object 31 and can adopt the various materials strong to electromagnetic wave obstructing capacity, generally directly use antitheft door as intercepting object, because electromagnetic penetrability, so intercept the very difficult realization of object 31, intercept electromagnetic wave completely, can only weaken to a certain extent electromagnetic signal intensity.In the inner side that intercepts object 31, there is a bluetooth module 11, in the outside that intercepts object 31, there is a bluetooth module 21, bluetooth module 11 and bluetooth module 21 are positioned at the both sides that intercept object, control circuit board 22 is generally positioned at the outside that intercepts object 31, but in part situation, also can be positioned at the inner side that intercepts object 31, according to the demand of mould, freely define, it should be noted that, do not mark in the diagram those metals of lock itself composition or the information such as shell of plastic material, but the people as the industry should be appreciated that, these building blocks are all outwardness.
The present invention can have 2 kinds of patterns, and a kind of pattern is locking system aggressive mode, i.e. locking system active searching handheld device; Another kind of pattern is handheld device active searching locking system.Two kinds of patterns are similar, difference is, in locking system situation initiatively, bluetooth module 11 and bluetooth module 21 all will be searched for handheld device around simultaneously, then by control circuit board 22, judge that handheld device is positioned at inner side or the outside of door, and in handheld device situation initiatively, be that handheld device is searched for equipment around, then judge it oneself is inner side or the outside for door.
The in the situation that of locking system active, because intercept the existence of object 31, add the impact of distance simultaneously, bluetooth module 11 and bluetooth module 21 search the signal intensity of handheld device 23 and affirm inconsistent, bluetooth module 11 is because signal is blocked and is distant, a little less than searching the signal intensity meeting of handheld device 23, and bluetooth module 21 is not because signal is blocked and close together, searching handheld device 23 signal intensities can be strong, both feed back to control circuit board 22 by the signal intensity searching separately simultaneously and process, the signal intensity of the handheld device 23 that control circuit board searches both contrasts, just nature can be judged the outside that handheld device 23 is now positioned at door, therefore can enter the flow performing unlocking action of unblanking.By same way, locking system also can be judged the inner side that hand hammer equipment 13 is positioned at door, and therefore refusal enters the flow process of unblanking.
The in the situation that of handheld device active, because intercept the existence of object 31, add the impact of distance simultaneously, the bluetooth module 11 that handheld device searches and the signal intensity of bluetooth module 21 are certainly inconsistent, bluetooth module 11 is because signal is blocked and is distant, so a little less than signal intensity meeting, and bluetooth module 21 is not because signal is blocked and close together, signal can be strong, handheld device 23 is according to the strong and weak situation of both signal intensities, just can naturally judge the outside that oneself is positioned at door, so enter the flow process of unblanking with locking system.Otherwise handheld device 13 also can judge the inner side that oneself is positioned at door, does not enter the flow process of unblanking.
