The embodiment of the utility model provides an elevator system, which is popularized and applied in buildings (particularly high-rise buildings), can better improve the elevator using safety of passengers in the elevator taking process compared with the existing elevator system, and can prevent the potential safety hazard that the passengers or goods excessively leaning on an outer door assembly 30 fall down to be hurt when the doors are opened and the passengers or goods fall down to collide other passengers to be hurt when the elevator is opened particularly in the elevator door opening process during the operation of the elevator.

As shown in fig. 1, the elevator system includes a car 10, a door pocket 20, an outer door assembly 30, a control device (not shown), a detection device 40, and an alarm device 50, which are combined to form a complete elevator system capable of performing elevator safety detection and early warning. The car 10 is provided with a car door assembly 11, and the passenger space in the car 10 is opened or closed through the car door assembly 11, so that the passenger space is in a closed state in the process of running and lifting of the car 10, and the running safety is ensured. In the installation process, the door pocket 20 is used to be assembled in a floor wall to form a door passage 21 communicating with the elevator hoistway (the floor wall refers to a wall with doors of the elevator hoistway, and is a broad wall, that is, the wall of the elevator hoistway can be not only a load bearing wall, but also a general partition wall, and can be used for installing the door pocket 20), and the outer door assembly 30 is assembled in the door pocket 20 to open or close the door passage 21. The door pocket 20 can support the floor wall body provided with the door channel 21, and the safety factor is improved. The control device is used for controlling the car door assembly 11 and the outer door assembly 30 to be synchronously opened or closed when the car door assembly 11 and the outer door assembly 30 are opposite, namely, after the car 10 reaches a floor selected by a passenger and is stably stopped, the control device controls the car door assembly 11 and the outer door assembly 30 to be synchronously opened so that the passenger can walk out of the passenger space of the car 10 along the door passage 21 or enter the passenger space of the car 10 through the door passage 21, then the control device controls the car door assembly 11 and the outer door assembly 30 to be synchronously closed, and then the car 10 moves up and down in the elevator shaft to reach a destination floor selected by the passenger.

Generally, passengers can stably stand without moving positions freely after entering the passenger space of the car 10, and because of the increasing awareness of safety and the increasing popularity of elevator use knowledge, there are few passengers or goods in the car 10 leaning on the door assembly 11. When passengers and goods carried by the passengers wait for the elevator at a floor, the passengers lean against the outer door assembly 30 or the goods lean against the outer door assembly 30 due to improper arrangement, which causes potential safety hazards that people or objects fall down or the landing door is damaged when the outer door assembly 30 is opened. In order to solve, eliminate or even avoid the above-mentioned potential safety hazard problem, the elevator system uses the detection device 40 and the alarm device 50 to realize the detection and alarm reminding functions. Specifically, the detection device 40 is in communication connection with a control device, the detection device 40 is used for forming a detection area 401 on the side of the door panel of the outer door assembly 30 facing away from the elevator hoistway, the detection device 40 is used for sending a trigger signal to the control device when an object enters the detection area 401, the alarm device 50 is in communication connection with the control device, and the control device controls the alarm device 50 to give an alarm according to the trigger signal when the outer door assembly 30 is closed. In fact, the detection device 40 detects the detection area 401 at any time, and as long as a passenger or cargo enters the detection area 401, the detection device 40 sends a trigger signal to the control device, and then the control device receives the trigger signal sent by the detection device 40. Then, the control device determines the operation of the entire elevator system, and particularly determines whether the car door assembly 11 and the outer door assembly 30 are in the open state or the closed state. When the control device determines that the car door assembly 11 and the outer door assembly 30 are in the open state, the control device does not control the alarm device 50 to give an alarm even if the control device receives the trigger signal transmitted from the detection device 40; when the control device determines that the car door assembly 11 and the outer door assembly 30 are in the closed state, and the control device receives the trigger signal sent by the detection device 40, the control device immediately controls the alarm device 50 to give an alarm to remind the passenger waiting for the elevator to lean against the outer door assembly 30 or remind the passenger waiting for the elevator to lean against the goods carried by the passenger on the outer door assembly 30.

Thus, with the elevator system provided by the embodiment of the present invention, the detection device 40 detects whether a passenger or cargo enters the detection area 401 (i.e., the passenger or cargo leans against the outer door assembly 30) in real time while the passenger and the passenger carrying the cargo wait for the elevator, and when the detection device 40 detects that the passenger or cargo enters the detection area 401, the detection device 40 sends a trigger signal to the control device. When the control device receives the trigger signal and judges that the car door assembly 11 and the outer door assembly 30 are in the closed state, the control device controls the alarm device 50 to give an alarm to remind passengers waiting for the elevator to pay attention not to lean on the outer door assembly 30 or remind passengers waiting for the elevator to pay attention not to lean on goods carried by the passengers on the outer door assembly 30; when the control device determines that the car door assembly 11 and the outer door assembly 30 are in the open state, the control device does not control the alarm device 50 to give an alarm (at this time, the elevator system is in a normal safe operation state, and the car door assembly 11 and the outer door assembly 30 are opened for passengers to get on or off the elevator). Therefore, the problem of potential safety hazards caused by passengers leaning on the outer door assembly 30 or goods leaning on the outer door assembly 30 due to improper placement is solved, eliminated and even avoided, and personal safety of the passengers in the process of using the elevator is ensured.

In the present embodiment, the detecting device 40 includes a transmitter 41 and a receiver 42, the transmitter 41 is used for emitting a signal, and the receiver 42 is used for receiving the signal emitted by the transmitter 41, so that a detecting area 401 is formed between the transmitter 41 and the receiver 42. When the receiver 42 is able to receive the signal sent by the transmitter 41, which means that no passenger or cargo enters the detection area 401, the detection device 40 does not send a trigger signal to the control device; when the receiver 42 cannot receive the signal sent by the transmitter 41, which indicates that the space between the transmitter 41 and the receiver 42 is blocked by an object, that is, a passenger or cargo enters the detection area 401, the detection device 40 sends a trigger signal to the control device. In a specific installation, the transmitter 41 is mounted on one of the opposing door posts of the door pocket 20, and the receiver 42 is mounted on the other of the opposing door posts of the door pocket 20, such that a detection zone 401 is formed adjacent to the outer door assembly 30, and passengers or cargo entering the detection zone 401 (passengers or cargo may already lean on the outer door assembly 30, or passengers or cargo may not yet lean on the outer door assembly 30, but may be in close proximity to the outer door assembly 30, have a tendency to lean toward the outer door assembly 30, and thus present a safety hazard) are detected by the detection device 40. The transmitter 41 and/or the receiver 42 are electrically connected to the control device, and when a passenger or cargo enters the detection area 401, the detection device 40 detects the passenger or cargo and sends a trigger signal to the control device.

Preferably, the transmitter 41 of the present embodiment is an infrared light transmitter, and correspondingly, the receiver 42 is an infrared light receiver. In other possible embodiments, the transmitter 41 and the receiver 42 may also use other sensing devices for detecting obstacles, such as a CCD detecting Device (CCD: Charge coupled Device, which is called CCD image sensor), and so on, as long as it can detect whether an object leans against the outer door assembly 30 or has a tendency to lean against the outer door assembly 30, and thus it is not limited herein.

As shown in fig. 1, the warning device 50 includes an in-car alarm 51 and a plurality of floor alarms 52. An elevator system in which one elevator shaft is correspondingly equipped will be described as an example. This elevator shaft is equipped with a doorway 21 in each floor, and the doorway 21 of each floor is equipped with at least one floor warning indicator 52 (can be a floor warning indicator 52, also can be two or more floor warning indicators 52) correspondingly, and all floors of the whole building that this elevator shaft corresponds all are equipped with floor warning indicator 52. One car 10 is installed and used in one elevator shaft, and since the passenger space of the car 10 is limited, it is sufficient to use one in-car alarm 51 in the passenger space of the car 10 (of course, two or more in-car alarms 51 may be installed). In the installation, the in-car alarm 51 is installed on the inner wall of the car 10, at least one floor alarm 52 is installed on the door pocket 20 or the wall of the floor close to the door pocket 20, and when the detection device 40 at any floor detects that an object enters the detection area 401 and the car door assembly 11 and the outer door assembly 30 at the floor are closed, the control device controls the in-car alarm 51 and the floor alarm 52 at the floor to simultaneously give an alarm. In this way, not only passengers waiting for the elevator at a floor will notice themselves slightly away from the outer door assembly 30 or passengers will move goods near the outer door assembly 30 slightly away from the outer door assembly 30, but passengers in the car 10 traveling up and down and about to reach the corresponding floor will also notice themselves, thereby keeping themselves slightly away from the door assembly 11 with self-notice, ensuring self-safety.

Specifically, the alarm device 50 may employ a sound device, may employ a light-emitting device, or employ both a sound device and a light-emitting device. In the elevator system of the present embodiment, it is preferable that the alarm device 50 employs both a sound device and a light device, that is, the in-car alarm 51 and the floor alarm 52 have both a sound emitting function and a light emitting function.

In the present embodiment, in order to ensure effective detection, therefore, the detection depth of the detection area 401 is L, 0.3 m.ltoreq.L.ltoreq.0.7 m (explanation: the detection depth refers to the covering distance of the detection area 401 in the direction of the upper and lower cars 10 of the doorway 21, and the detection width of the detection area 401 is the distance between the jambs on both sides of the doorways 20, and the detection height of the detection area 401 is the height of the doorways 20). Preferably, the detection depth L is 0.5 m.

Further, the elevator system also comprises a general control platform, and property personnel or security personnel of the building can monitor the general control platform specially. The control device is in communication connection with the master control platform and is used for sending a notification signal to the master control platform when the time that the object stays in the detection area 401 exceeds the preset time. Generally, when a passenger leans on the outer door assembly 30 or goods carried by the passenger leans on the outer door assembly 30, the sensing device 40 senses and immediately sends a trigger signal to the control device, and the control device controls the alarm device 50 to give an alarm when it is judged that the outer door assembly 30 is in a closed state, thereby alerting the passenger waiting for the elevator to notice. However, if the detection device 40 still detects the presence of an object in the detection area 401 after the alarm device 50 has been alerted and a relatively long alarm has been alerted, the control device triggers a determination that the object leaning on the outer door assembly 30 is a passenger leaning on the outer door assembly 30 without waking up (getting drunk, dizzy or even getting dizzy), and the control device sends a signal to the general control platform to alert the person monitoring the general control platform. Therefore, monitoring personnel can monitor the floors or directly arrange the personnel to check in the past and process in time, and personal safety of passengers is ensured. And, the control device will control the arriving car 10 to slow down the door opening speed when opening the car door assembly 11 and the outer door assembly 30 while sending signals to the general control platform, so that the passenger in the car 10 can find the person leaning on the outer door assembly 30 in time, thereby applying the assistant to hold in time to prevent the passenger from falling down suddenly in the car 10 to cause the injury.

To further ensure the personal safety of passengers during boarding and waiting for the elevator, the elevator system further includes an in-car detection device 60, as shown in fig. 1, for detecting whether passengers or goods in the car 10 lean against the door assembly 11 by using the in-car detection device 60. Specifically, the in-car detection device 60 is in communication connection with the control device, the in-car detection device 60 is mounted on the inner wall of the car 10, the in-car detection device 60 is used for forming an in-car detection area 402 inside the car 10 and near the door panel of the car door assembly 11, and the control device controls the in-car alarm 51 and the floor alarm 52 of the floor to be reached to give an alarm when the car door assembly 11 is closed and an object enters the in-car detection area 402. Thus, when passengers or cargo of the car 10 lean against the door assembly 11, the in-car alarm 51 gives an alarm to warn passengers in the car to keep a certain distance from the door assembly 11, and the floor alarm 52 of the corresponding floor also reminds passengers waiting for the elevator to keep a certain distance from the oncoming car 10, thereby slightly keeping the distance from the outer door assembly 30, thereby ensuring safety.

In the present embodiment, the in-car detection device 60 and the detection device 40 have the same structure, that is, both the in-car detection device 60 and the detection device 40 preferably employ an infrared light emitter and an infrared light receiver.

As shown in fig. 1, the in-car detection area 402 is a detection plane parallel to the panel surface of the door panel of the door assembly 11, so that the internal space of the car 10 is saved as much as possible, and the space utilization of the car 10 is improved. In the embodiment, the distance between the detection plane and the plate surface of the door plate of the car door assembly 11 is H, wherein H is more than 0 and less than or equal to 10cm, and preferably, H is more than 3cm and less than or equal to 5 cm.

The above description is only for the purpose of illustrating the preferred embodiments of the present application and is not intended to limit the present application, and any modifications, equivalents and improvements made within the spirit and principle of the embodiments of the present application should be included in the scope of the present application.
