What are the basic precautions for access control coil?
Information from:internet Published on:2022-03-02
At present, enterprises need to swipe their cards to get in and out of work, and they can only enter when they hear the sound of "drop", which is controlled by the induction coil of access control. Access control induction coil is divided into receiving coil and transmitting coil. Our ID card and IC card are receiving coils, and our access control system machine is transmitting coils. The transmitting coil of the access control system sends out a signal and receives the IC and ID card. One sending and one receiving is the completion of one work. So what should be paid attention to in the induction coil of access control? (1) The device orientation of the access control induction coil shall meet the planning requirements The device orientation of the coil and the relative orientation of the chip element should conform to the planning rules, otherwise the normal operation of the access control system will be affected. (2) The appearance of the induction coil of access control shall be checked before the installation Before use, check whether the structure of the induction coil is solid, whether the wire turns are loose and loose, whether the lead contact is loose, whether the magnetic core rotation is sensitive, whether there are sliding buckles, etc. After these aspects are checked to be qualified, the coil can be installed. (3) If the access control induction coil needs to be fine tuned in the application process, the fine-tuning method should be considered Some launch coils need to be fine tuned in the application process. It is inconvenient to rely on changing the number of coil turns and the flat coil. Therefore, the method of fine tuning should be considered when selecting. (4) When using access control induction coil, pay attention to the inductance of the original induction coil Do not change the shape of the induction coil when using it. Size and spacing between coils, otherwise it will affect the original transmitting and receiving inductance of access control induction coil. (5) The device of access control induction coil shall be easy to adjust The access control induction coil shall be installed in the position where the ID, IC card and access control system are easy to adjust, so as to adjust the inductance of the access control induction coil to achieve the best operation state.
