Rope-type anti-theft device and alarm elimination method thereof

A rope-type anti-theft device, comprising:

• a device body, wherein a control module, a logic switch module, and a power module are provided in the device body;
• the power module is configured to supply power to the control module;
• the logic switch module comprises a first logic level switch circuit and a second logic level switch circuit;
• the first logic level switch circuit is electrically connected to a first input port of the chip in the control module, and the first logic level switch circuit is provided with a first switch;
• when the first switch is in a connected state, the first input port is at a low level;
• when the first switch is in a disconnected state, the first input port is at a high level;
• and the first switch is connected or disconnected by a button located on a housing of the device body;
• wherein the first switch serves as an unlocking switch in the device body;
• and is in the disconnected state when the rope-type anti-theft device is in an unlocked state;
• the second logic level switch circuit is electrically connected to a second input port of a chip in the control module, and the second logic level switch circuit is provided with a second switch;
• when the second switch is in a connected state, the second input port is at a low level;
• when the second switch is in a disconnected state, the second input port is at a high level;
• and the second switch is connected or disconnected by an anti-theft rope in the device body, causing an alarm to be set off by the anti-theft rope being cut in a unlocked state of the rope-type anti-theft device.
