Access control card reader convenient to maintain

Abstract

The invention relates to the technical field of card readers, and provides an access control card reader convenient to maintain. The access control card reader convenient to maintain comprises a device body, wherein the upper end of the device body is provided with a reading panel, a frame is connected to the lower end of the device body and located right below the reading panel, an operation panel with keys is arranged at the lower end of the device body and located on the inner side of the frame, the outer end surface of the operation panel is connected with a film sheet, and the upper sideand the lower side of the right end of the film sheet are fixedly connected with clamping blocks. Through the arrangement of the frame, the clamping blocks, buffer springs and other structures, a worker can replace the film sheet conveniently, the replacement purpose can be achieved without disassembling the whole device body, and the collision bearing capacity of the access control card reader ishigher, so that the access control card reader can be effectively prevented from being collided and damaged. In conclusion, workers can maintain the device body conveniently, the access control cardreader can be used more safely, and the self-collision prevention and shock absorption capacity is improved.

Description

technical field [0001] The invention relates to the technical field of card readers, in particular to an access control card reader which is convenient for maintenance. Background technique [0002] The non-contact IC card (inductive IC card) card reader for access control is an important part of the access control system and the key equipment for signal input of the access control system, which is related to the stability of the entire access control system. Send out electromagnetic waves, when the proximity card enters the electromagnetic wave radiation range of the card reader, it will trigger the coil on the proximity card, generate current and trigger the antenna on the proximity card to send a signal to the card reader, and the card reader converts the level signal into The digital serial number is sent to the local controller, and the local controller uploads the information to the upper controller, and finally to the access control server, and the access control serv...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an access control card reader that is easy to maintain, which not only facilitates the replacement of the film, improves the replacement efficiency, facilitates maintenance, improves the safety of use, but also plays a better role. The advantages of anti-collision and shock absorption effect solve the problem that when the existing access control card reader is easy to maintain, the access control card reader needs to be used frequently, and the access control card reader is not only operated through the access control card, but also through the access control card reader. For a long time, you need to use the buttons on the access control card reader to open the door, and after the buttons are used for a long time, the film on the buttons will fade or even be damaged, so criminals can easily guess the access code, but the film is more difficult For replacement, most of the access control card readers need to be disassembled for replacement and maintenance, and even the film on the access control card reader cannot be replaced after being damaged, which leads to the problem that the use safety of the access control card reader is reduced
