Description

Elevator installation with security mode

Generally speaking, this creation is related to the elevator installation. In particular, it concerns elevator installations with a security mode.

Of course, when unexpected disasters such as earthquakes or fires occur, elevators should be avoided to avoid danger. But in general, elevators are pretty safe. Especially the design and operation of elevator products are restricted and supervised by laws and regulations to ensure the safety of elevator structure and operation.

For example, when the elevator car runs to the leveling zone (the position where the floor of the elevator car and the floor of the floor are kept at the same level), the car door can be opened from the inside or outside of the elevator car to facilitate the entry and exit of passengers. But when the elevator car moves to the non-leveling area (i.e. a position outside the leveling area), in order to prevent passengers from falling into the elevator shaft, a simple safety measure is to lock the elevator car door. For this, please refer to the elevator standards of various countries, such as China's GB 7588-2003 Amendment No. 1 or the European Union's EN 81-20:2014.

In order to lock the elevator car door in the non-leveling area, a door lock can be installed on the elevator car in the prior art, especially a door knife with a lock can be used. For this, reference can be made to, for example, CN205772705U, CN105438941, CN105035921 and the like.

As mentioned above, except when an accident occurs, generally speaking, the safety of the elevator is high. Especially in order to avoid injuries caused by improper use of passengers, the structure of the elevator is also quite strong and difficult to break. bad.

<Elevator car as a security space>: In view of this, this case first realized that as long as the elevator car door is kept closed, it is not easy to leave from the inside of the elevator, or it is also very difficult to enter from the outside. Therefore, the elevator car can be used as a safe space when emergency evacuation (or called emergency avoidance) occurs, that is, in order to protect the life, body, freedom, and property of oneself or others, the elevator car can be used to connect passengers with the outside world. The threat hazard (such as an offender) can be temporarily isolated (so that the offender cannot enter the elevator car), or the threat can be confined to the elevator car (so that the offender cannot exit the elevator car).

This case further recognizes that, according to general elevator standards and regulations, when the elevator car runs to the leveling area, it is not particularly difficult to manually open the car door from the inside or the outside, so it cannot fully meet the threat and harm (such as criminals) ) for the purpose of isolation. Taking EN 81-20:2014 of the European Union as an example, it requires that when the elevator car reaches the leveling area, the car door (inner door) and landing door (outer door) of the elevator car can be manually opened with a force not exceeding 300N.

In contrast, when the elevator car runs to the non-leveling area, if a force of 1000N is applied, the door of the elevator car can only be opened by about 50mm, which is almost impossible for ordinary adults. Therefore, one of the characteristics of the elevator to be proposed in this case is a security mode. In this security mode, the elevator car will remain in the non-leveling area, making it difficult to open the elevator car door or make it difficult to enter and exit the elevator car, thereby preventing threat hazards (such as criminals) from entering the elevator car, or Temporarily prevents threat hazards from leaving the elevator car until security mode is lifted.

In detail, the present invention proposes an elevator device in an embodiment, comprising: an elevator car (car); a control module for controlling the operation of the elevator car; wherein the control module can be configured to activate A security mode. In the security mode, the control module controls the elevator car to move to the non-leveling area, and keeps the elevator car in the non-leveling area until a release instruction is received.

In other embodiments, the elevator device can have various detection or identity recognition modules, which can help determine whether to activate the security mode through various means such as image recognition or voice recognition.

In addition, in other embodiments, the elevator device can also be provided with a communication module, so that when the security mode is activated, the pre-designated object, such as the management room or service center, can be notified immediately according to the preset settings.

<Security Mode>

In particular, the control module 10 is configured to have a security mode. The following will be further described with reference to FIG. 2A and FIG. 2B .

Under normal circumstances, the control module 10 will first control the elevator car 1 to move to the leveling area for passengers to enter and exit the elevator car 1 , as shown in FIG. 2A . The elevator car 1 has a car door lock 30 which further has a door knife 32 . When the elevator car 1 was in the leveling area, the car door lock 30 was unlocked, and the door knife 32 stretched out and inserted the gate ball 34 to drive the landing door (outer door) to open. This part can refer to the existing door knife with lock, so it will not be repeated here.

In addition, the scale device 17 (shown in FIG. 1 ) can detect whether there are passengers in the elevator car 1 according to the carrying weight of the elevator car 1, and the detection result can be provided to the control module 10 as whether to activate the security mode One of the judgment parameters. In addition to the scale device 17, the elevator car 1 can also be photographed through the video camera 16 (shown in FIG. Shown in FIG. 1) is equipped with a highly sensitive microphone, which can also detect whether there are passengers in the elevator car 1 by detecting the sound of speaking or breathing.

If it is detected that there is a passenger in the elevator car 1 through the above method, the identity of the passenger can be further identified and compared with the pre-recorded white list or black list. The result of the identification can also be provided to the control module 10 as one of the parameters for judging whether to activate the security mode. The way of identity recognition can be through the camera 16 to shoot the face of the passengers in the elevator car 1, and provide the image to the control module 10 for image recognition, or through the microphone equipped in the walkie-talkie 15, obtain the face of the passenger in the elevator car 1. Passenger's voice, and provide the voice to the control module 10 for voiceprint recognition of the voice. not shown In the embodiment, the elevator car 1 can also be equipped with a fingerprint collection module, which can collect the fingerprints of passengers and provide them to the control module 10 for identification.

In addition to the above-mentioned judging parameters based on whether there are passengers in the elevator car 1 and the identity of the passengers, it can also be based on the time (for example, late at night) or the floor where the elevator car 1 stopped for the last time, for example. Or in another embodiment, in addition to providing the voice to the control module 10 for voiceprint recognition to identify the identity of the passenger, the microphone equipped in the walkie-talkie 15 also further detects the identity of the passenger. Whether the voice contains a specific word (such as "help") is used as a judgment parameter for whether to activate the security mode.

However, in another embodiment, for example, an escape handle (not shown) may also be provided in the elevator car 1 to connect with the control module 10, and when the escape handle is pulled down, the control module 10 immediately activates the security mode, without any judgment.

Once the security mode starts, as shown in Figure 2B, the control module 10 controls the elevator car 1 to move from the leveling area (it can be raised or lowered) to the non-leveling area, and keeps the elevator car 1 staying in the non-leveling area, that is Do not continue to move. At this time, the control module 10 ignores the command to call a car no matter it is sent from the boarding area or inside the elevator car 1 through the general elevator interface (such as a button), and continues to keep the elevator car 1 in the non-leveling area.

At the same time, when the elevator car 1 moves from the leveling area to the non-leveling area, the car door lock 30 will automatically lock the car door of the elevator car 1, that is, even if a force of 1000N is applied, only the car door of the elevator car 1 can be locked. is opened about 50mm.

On the other hand, when the security mode is activated, the control module 10 controls the communication module 11 to notify a pre-designated object of the security mode activation information, such as the service of the elevator device 100. Center or management office of a building, etc. After the service center or management room knows that the security mode is activated, it can connect with the control module 10 through the communication module 11, and can understand the situation in the elevator car 1 through the pictures taken by the camera 16, or through the intercom 15 Talk to the passengers in the elevator car 1 to provide suitable disposition measures. It is worth mentioning that, in order to let the service center or the management room understand the situation in the elevator car 1 and communicate with the elevator car 1, the walkie-talkie 15 and the camera 16 can be directly connected to the communication module 11 respectively, and no additional control is required. Module 10.

If the service center or the management room judges that the emergency situation has been resolved, it can issue a release command by remote control. The release command can be sent to the control module 10 through the communication module 11, and the control module 10 can complete the emergency after receiving the release command. Release the security mode to restore the normal operation of the elevator device 100 . In another embodiment, the control module 10 also allows the passenger to enter the password through the keyboard (not shown) in the elevator car 1, or speak the password or password to the walkie-talkie 15 to issue a release command to the control module 10. Disable security mode.

Two usage scenarios are provided below, and the invention can be described more specifically with reference to FIG. 2A and FIG. 2B .

<Use scenario 1>

The elevator device 100 is installed in a villa, and the owner goes out on vacation so that there is no one at home for many days. Before going out, the homeowner can set the activation condition of the security mode as "when a stranger uses the elevator during the holiday, the security mode will be activated". Therefore, when the owner is away on vacation, if a thief invades, and once the thief uses the elevator device 100, the control module 10 can judge that someone is using the elevator device 100 through the information of the load capacity detected by the scale device 17 (shown in FIG. 1 ). Use the elevator. At the same time, the camera 16 (shown in FIG. 1 ) can immediately take an image of the thief's face and send it to the control module 10 for identification.

In this example, the result of identification shows that the thief is not a member of the family, so the control module 10 can immediately start the security mode (or wait for about 5 seconds after the thief enters the elevator car 1 to avoid arousing the thief's vigilance. After the bell, or wait for the thief to press the floor button or close the door button and then start), the elevator car 1 is moved from the leveling area to the non-leveling area. And because elevator car 1 can be locked by car door lock 30 when elevator car 1 is in the non-leveling area, the thief is allowed to stay in elevator car 1 and can't leave temporarily by this, and inform the house owner or Management came to deal with it.

<Use scenario 2>

The elevator device 100 is also installed in a house in a remote area, and the house owner has only one person at home. The homeowner can set the activation condition of the security mode as "when the homeowner uses the elevator and shouts "Help", the security mode will be activated". Therefore, if a thief invades the house, the owner can flee to the elevator device 100 for refuge and shout "Help".

In this example, the control module 10 can obtain the voice signal through the microphone of the walkie-talkie 15 (shown in FIG. 1 ) for voiceprint recognition, and judge that the passenger is the owner of the house, and further judge that the voice signal contains "help". " words, so the control module 10 starts the security mode to move the elevator car 1 from the leveling area to the non-leveling area. And because the car door can be locked by the car door lock 30 when the elevator car 1 is in the non-leveling area, the house owner is allowed to stay in the elevator car 1 so that the thief cannot approach, and immediately inform the security unit or management personnel to come assist.
