Description
Technical field
A kind of gate control system, espespecially utilize and judge active contactless card moving direction, when moving towards main frame direction to allow active contactless card, accelerate the control signal transmission speed of active contactless card, wait for that to avoid active contactless card main frame performs the gate control system of control signal.
Background technology
Press, current most of gate control system utilizes the active contactless card entrained by user to send control signal with intermittent mode to be sent to main frame execution, therefore, after user is close to main frame, main frame will automatically perform control signal, quite convenient, but this kind of way easily causes the control signal that host process is too much unnecessary, therefore the inventor of this case develops the Remote control device for door of a kind of tool control area setting then, it mainly utilizes the signal strength values set by main frame to define effective first range of receiving, to avoid the control signal that host process is too much unnecessary, or the control signal that active contactless card sends is simultaneously performed by multiple host.But because active contactless card sends control signal with intermittent mode, after often making active contactless card enter effective first range of receiving of main frame, a period of time just sends control signal, the deficiency of time causing main frame to perform control signal allows user wait for.
Therefore above-mentioned known problem and disappearance how will be solved, be relevant dealer desire most ardently the problem place of research and development.
Summary of the invention
Fundamental purpose of the present invention is, utilize the moving direction of the active contactless card of main frame comparison, to allow active contactless card when moving towards the direction near main frame, main frame first sends and changes signal and allow active contactless card intermittently to send control signal shorter interval time, to avoid waiting for that main frame performs the time of control signal.
For reaching above-mentioned purpose, gate control system of the present invention has main frame and active contactless card, main frame defines one first range of receiving, and in the first range of receiving, define one first effective range, active contactless card controls signal to main frame with intermittent sending the first interval time, when active contactless card be positioned at the first range of receiving send control signal time, main frame can judge the moving direction of active contactless card, if active contactless card towards main frame near time, then main frame sends and changes signal to active contactless card, allow active contactless card intermittently to send control signal the second interval time, and the second interval time was shorter than for the first interval time.
