[0002] The elevator floor door lock is installed on the elevator floor door of the elevator station. It is used to open the floor door to rescue trapped passengers or perform maintenance when the elevator fails or is under maintenance. The floor door lock device is a mechanical structure that can be opened with a special elevator key. However, in reality, accidents such as falling into the elevator shaft after unlocking the door due to illegal operation or negligence are often heard. Therefore, the existing floor door unlocking has the following problems: (1) The special elevator key is difficult to control. The key is a common standard part that can be purchased at will in the market and is compatible with the keys of other related equipment. Therefore, it is very easy to be abused and cause accidents; (2) Floor door unlocking is a professional behavior. Technical standards and regulations require that non-professionals and non-emergency rescue or maintenance behaviors shall not open the floor door at will.

[0022] The above-mentioned elevator floor door lock is provided with a reading module, which reads the information of the authorized personnel and sends the information to the processing module. The processing module identifies the information, and after successful identification, sends an electrical signal to the power-on structure 4 to enable it to be powered and finally unlocked, thereby solving the problem that the elevator unlocking behavior is uncontrollable, resulting in frequent falling and injuring accidents at the elevator floor door; by providing the power-on structure 4, the power-on structure 4 uses its own power-on and power-off state to control the telescopic movement of the push rod 3, so that the push rod 3 can reciprocate and abut and lift the boom 1, and then the lock hook 11 on the boom 1 can reciprocate and engage the lock body 2, thereby realizing the control of the locking state of the floor door lock.

In this way, the fingerprint or digital password input by the authorized person can be identified to prevent unauthorized persons from opening the door at will.

[0024] Furthermore, the reading module also includes an NFC submodule, and can also be identified through the input NFC.

[0025] In one embodiment, the processing module includes an identification submodule and a control submodule that is communicatively connected to the identification submodule, the identification submodule is communicatively connected to the fingerprint submodule and the password submodule respectively and is used to identify the authorized personnel information, and the control submodule is used to control the power-on and power-off state of the power-on structure 4. In this way, after the information is correctly identified, the control submodule can control the power-on structure 4 to be powered on.

[0026] In one embodiment, the identification submodule is preferably a processing chip FH8896.

[0027] In one embodiment, the control unit further includes a positioning module and a power module, the power module is electrically connected to the identification submodule, one end of the positioning module is communicatively connected to the identification submodule, and the other end of the positioning module is communicatively connected to the elevator management platform. The positioning module sends unlocking information to the elevator management platform, including time, location, authorized person code, etc.

[0028] In one embodiment, the energized structure 4 is an electromagnet.

[0031] Working principle:

[0032] The information of the authorized personnel (including fingerprints, digital passwords, etc.) is pre-written into the control submodule. When the floor door lock needs to be opened for emergency rescue or maintenance, the authorized personnel contacts the identification submodule and is identified. The control submodule records the time, location, and information of the authorized person. When the control submodule recognizes that the information is correct, it sends a command to the power-on structure 4 to energize the electromagnet, and the iron core 41 is magnetized. Under the action of the magnetic force, the top rod 3 in the iron core 41 extends, driving the boom 1 to lift, so that the lock hook 11 on the boom 1 is separated from the lock body 2, and the elevator floor door is unlocked. In addition, the electromagnet is energized with a delay. When the preset delay ends, the electromagnet loses power, the top rod 3 resets and retracts, the lock hook 11 on the boom 1 resets and engages the lock body 2, and the elevator floor door is locked. This unlocking action ends, and the next cycle begins, waiting for a new unlocking command.
