Description
Technical field
A kind of gate control system, espespecially using active contactless card moving direction is judged, to make active contactless card direction main
When machine direction is moved, accelerate the control signal transmission speed of active contactless card, to avoid active contactless card from waiting main frame to hold
The gate control system of row control signal.
Background technology
Press, current most of gate control systems are with intermittent mode to send control using the active contactless card entrained by user
Signal is sent to main frame execution, and therefore, after user is close to main frame, main frame will perform control signal automatically, quite facilitates, but
Such a way easily causes the excessive unnecessary control signal of host process, therefore the inventor of this case develops a kind of tool control then
The Remote control device for door of region setting processed, it mainly uses the signal strength values set by main frame to define effective first and connect
Scope is received, to avoid the excessive unnecessary control signal of host process, or the control signal that active contactless card is sent is same
When performed by multiple host.But, because active contactless card is to send control signal with intermittent mode, often make active
Contactless card enters after effective first range of receiving of main frame just sends control signal for a period of time, causes main frame to perform control signal
Time deficiency allow user to wait.
Therefore the problem of how solving above-mentioned known and missing, are the problem place that related dealer desires most ardently research and development.
The content of the invention
It is a primary object of the present invention to compare the moving direction of active contactless card using main frame, to allow active sense
When should be stuck in towards close to the movement of the direction of main frame, main frame first sends change signal when allowing active contactless card with shorter interval
Between it is intermittent send control signal, with avoid waiting for main frame perform control signal time.
For up to above-mentioned purpose, gate control system of the invention has main frame and active contactless card, main frame has defined one
One first effective range is defined in one range of receiving, and the first range of receiving, active contactless card is with the first interval time
The intermittent control signal that sends is to main frame, when active contactless card sends control signal positioned at the first range of receiving, main frame
The moving direction of active contactless card can be judged, if active contactless card towards main frame close to when, main frame sends change signal
To active contactless card, allow active contactless card with the second interval time it is intermittent send control signal, and during the second interval
Between be shorter than for the first interval time.

Enclose 3 and define one first effective range 4, and the first range of receiving 3 is more than the first effective range 4.
The active contactless card 2 is provided with the second microprocessor 21, the second microprocessor 21 be connected with secondary signal receive/
Emitter 22, the second microprocessor 21 is set with the first interval time 211 and the second interval time 212, and during the first interval
Between 211 be longer than for the second interval time 212, and active contactless card 2 connects secondary signal according to the first interval time 211 transmits/receives
Injection device 22 sends control signal with interval mode.
The first signal reception/emitter 12 of foregoing main frame 1 can be omni-directional or directive property, and the first signal receive/
The range of receiving of first signal reception/emitter 12 is defined first and connect by the first receiving sensitivity 121 of emitter 12
Scope 3 is received, for example：When first receiving sensitivity 121 is -96DBM, the first signal reception/emitter 12 can only receive signal
Intensity is more than -96DBM signal, because secondary signal reception/emitter 22 of active contactless card 2 sends control signal
Afterwards, control signal can produce strength retrogression because of distance and the external environment influence of transmission, if therefore the distance of active contactless card 2
Main frame 1 too far, when the control signal for being sent active contactless card 2 is sent to main frame 1, control signal strength retrogression to-
Below 96DBM, the first signal reception/emitter 12 can not receive this control signal, and active contactless card 2 must more be connect
Nearly main frame 1 reduces the decay of control signal, when the control signal is sent to the first signal reception/emitter 12, control
Signal intensity is reached more than -96DBM, and control signal could be allowed to be received by the first signal reception/emitter 12；Furthermore, by

Degree, represents active contactless card 2 and is moved towards main frame 1, that is, active contactless card 2 is ready to pass through the gateway in parking lot 5
51, then main frame 1, which is sent, changes signal to active contactless card 2, makes active contactless card 2 intermittent with the second interval time 212
Send control signal, to accelerate the interval transmission speed of control signal, allow active contactless card 2 enter the first effective range
When 4, control signal can be sent out in real time and allows main frame 1 to perform.
Furthermore, after main frame 1 receives the control signal that active contactless card 2 is sent, during the last period of meeting and setting
In (such as set first 5 days) receive the control signal that the active contactless card 2 sent and be compared, by multiple letter
Number strength ratio pair, more correctly to judge whether active contactless card 2 moves towards main frame 1.
Refer to shown in Fig. 1 and Fig. 5, it can be clearly seen from the figure that, when active contactless card 2 is in the first range of receiving 3
