Magnetic lock
The embodiment of the invention discloses a magnetic lock which comprises an iron plate installed on a door plate, an electromagnet installed on a door frame and a pull plug installed in the iron plate, and the electromagnet is provided with a slot which is opened in the attraction face of the electromagnet and extends towards the bottom face of the electromagnet. The core shaft is inserted into the slot, the tail end of the core shaft is provided with a pressure sensor, the Hall sensor is arranged on the surface of the electromagnet, the control circuit is connected with the pressure sensor, the Hall sensor and the electromagnet, and the control circuit comprises a preprocessing circuit, an analog-to-digital conversion circuit and a single chip microcomputer. The magnetic lock can linearly read the current pressure, is high in precision, can automatically carry out zero clearing and resetting, guarantees the precision and repeatability (+/-1%), is simple in circuit, is good in working stability, is high in response speed, is high in precision, is moderate in cost, and is suitable for large-scale production.
本发明实施例公开了一种磁力锁，包括：安装于门板上的铁板、安装门框上的电磁铁、安装于铁板中的拉栓，电磁铁具有在其吸合面上开口并向其底面延伸的插槽，插槽中插有芯轴并且末端装有压力传感器、设置在电磁铁表面的霍尔传感器、以及与压力传感器、霍尔传感器、电磁铁连接的控制电路，其中，所述控制电路包括：预处理电路、模数转换电路及单片机。该磁力锁可线性读出当前的压力，精度高，可自动进行清零和重置，保证了精度和重复度(±1％)，此外，电路简洁，工作稳定性好，响应速度快，精度高，成本适中，适合大批量产。
