The method for detecting the foreign matter in the elevator door clamp provided by the invention can be applied to the application scene shown in fig. 1, and fig. 1 is an application scene diagram of the method for detecting the foreign matter in the elevator door clamp in one embodiment, wherein an elevator 102 communicates with an elevator monitoring center 104 through a network. The elevator 102 may control the elevator door panel closing via an elevator door motor therein.
As shown in fig. 2, fig. 2 is a schematic structural diagram of normal closing of an elevator in the method for detecting the foreign matter in the elevator door clamp in one embodiment. The elevator door panels 302 can be devices which are arranged on four sides of an elevator car and used for enabling the elevator to be in an open or closed state, and the elevator door panels 302 can be hung on a guide rail frame of the elevator and are dragged by an elevator door motor to open and close the elevator door. The guide rail frame may be a member for supporting and fixing the guide rail, which may be installed on the wall of the hoistway or the cross member. It fixes the spatial position of the guide rail and takes up various actions from the guide rail. The elevator door motor may be a device that controls the opening and closing operation of the elevator door panel 302 and includes an encoder therein.
After the elevator 102 can control the elevator door panel 302 to be closed through the elevator door panel 302, the door closing moment of the elevator door motor can be cancelled after the elevator door panel 302 is closed, so that the elevator door panel 302 rebounds, the rebounding distance after rebounding and the rebounding speed in the rebounding process are obtained, whether the elevator door panel 302 clamps the foreign matter 404 or not is determined according to the rebounding distance and/or the rebounding speed, and meanwhile, the elevator door panel can also communicate with the elevator monitoring center 104 through a network to inform related personnel to check the elevator.
The elevator 102 may be, but is not limited to, various passenger elevators, freight elevators, medical elevators, sundry elevators, sightseeing elevators, vehicle elevators, ship elevators, building construction elevators, and the like, the elevator monitoring center 104 may be a terminal device, such as a PC, and the like, and the elevator monitoring center 104 may also be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, a method for detecting a foreign object in an elevator door clamp is provided, referring to fig. 4, fig. 4 is a schematic flow chart of the method for detecting a foreign object in an elevator door clamp in an embodiment, which is described by taking the method as an example applied to the elevator in fig. 1, and the method for detecting a foreign object in an elevator door clamp may include the following steps:
in step S201, when it is detected that the elevator door panel 302 is fully closed, the door closing torque of the elevator door motor is cancelled, so that the elevator door panel 302 rebounds.
In the present embodiment, as shown in fig. 3, fig. 3 is a schematic structural view of a method for detecting a foreign object caught in an elevator door in one embodiment, in which the foreign object is caught when the elevator is closed. The elevator door motor may control the door of the elevator door panel 302 to close by applying a moment to the elevator door panel 302 in the door closing direction. The magnitude of the moment of closing the door is not limited. The normal door closing condition of an elevator can be as shown in fig. 2, with the elevator door motor controlling the elevator door panel 302 to fully close. The elevator can confirm that the elevator door panel 302 is completely closed after the car door lock is locked through the car door lock arranged in the elevator. However, when the elevator door panel 302 has a foreign object 404 trapped therein, the elevator door panel 302 cannot be completely closed. For example, as shown in fig. 3, when the elevator door motor is installed at the upper part of the elevator, and the elevator door panel 302 is clamped with the foreign object 404 in the closing process of the elevator door panel 302, the elevator door panel 302 can still be closed, but the foreign object 404 is still arranged at the lower part of the elevator door panel 302 at this time, and the elevator door panel 302 can be in an "a" shape at this time; when the elevator door motor is installed at the lower part of the elevator, and the elevator door panel 302 clamps the foreign matter 404 in the closing process of the elevator, the elevator door panel 302 can be in a V shape at the moment. Because the elevator car door lock installed on the elevator door panel 302 can be closed, the elevator at this time meets the operating conditions, however, if the elevator is operated at this time, the potential safety hazard of the elevator can be caused.
The door closing torque of the elevator door motor is cancelled, allowing the elevator door panel 302 to rebound. The spring back may be a movement of the elevator door panel 302 in a direction opposite to the direction of the door closing after the door closing moment is lost. When no foreign matter 404 is clamped between the elevator door panels 302, the elevator door panels 302 can rebound after the door closing moment of an elevator door motor is cancelled, and the rebound distance and/or rebound speed are/is smaller; when a foreign object 404 is interposed between the elevator door panels 302, the elevator door panels 302 may also rebound after the door closing torque of the elevator door motor is cancelled, and the rebound distance and/or rebound speed at this time is large.
In step S202, the rebound distance and the rebound velocity of the elevator door panel 302 are obtained.
As shown in fig. 5, fig. 5 is a schematic structural diagram of an elevator after rebounding in the method for detecting a foreign object in an elevator door clamp according to one embodiment. The elevator door panel 302 generates a spring back distance and a spring back velocity upon spring back. Wherein the spring back distance may be the distance between the elevator door panel 302 from a position where the elevator door panel 302 is closed to a position where the spring back is at rest after the spring back is over. The spring back velocity may be the velocity that occurs during the period of time that the elevator door panel 302 moves to a position at rest after the end of spring back during spring back. The rebound velocity may be a maximum velocity, an average velocity, or an instantaneous velocity at a certain time during the rebound process, and the specific manner is not limited. As shown in fig. 5, the elevator door panels 302 are stationary after the door rebounds are completed, and a foreign object 404 is interposed between the elevator door panels 302, so that the elevator door panels 302 move in the door opening direction after the door closing moment is removed, and the vertical state, i.e., the door rebounds, is restored. The elevator door motor can record the rebound distance and rebound speed through an encoder arranged in the elevator door motor. The number and structure of the encoders are not limited.
In step S203, it is determined whether the elevator door panel 302 has a foreign object 404 according to the rebound distance and/or the rebound speed.
As shown in fig. 5, fig. 5 shows a state after the end of the rebound of the elevator door panels 302, and the elevator door panels 302 cannot be completely closed because a foreign object 404 is interposed between the elevator door panels 302. The elevator door motor can record the rebound distance and the rebound speed of the elevator door panel 302 by using an encoder arranged inside the elevator door motor, and because the rebound distance and/or the rebound speed of the elevator door panel 302 when the foreign matter 404 is not clamped is smaller and the rebound distance and/or the rebound speed when the foreign matter 404 is clamped is larger, whether the elevator door panel 302 clamps the foreign matter 404 can be determined according to any one or two of the rebound distance and the rebound speed.
In one embodiment, determining whether the elevator door panel 302 contains a foreign object 404 based on the spring back distance and/or the spring back velocity comprises: if the spring back distance reaches a first threshold value, and/or if the spring back speed reaches a second threshold value, it is determined whether the elevator door panel 302 has a foreign object 404 trapped therein.
In this embodiment, the encoder in the elevator door machine can be compared resilience distance and the first threshold value of settlement, compare resilience speed and the second threshold value of settlement, whether the encoder in the elevator door machine can be greater than first threshold value according to resilience distance, perhaps whether resilience speed is greater than the second threshold value and judges whether to accompany foreign matter 404 between elevator door plant 302, in addition, the encoder in the elevator door machine can also be through judging whether to accompany foreign matter 404 between elevator door plant 302 with corresponding threshold value comparison together with resilience distance and resilience speed, judge together combining resilience distance and resilience speed, can judge whether to accompany foreign matter 404 between elevator door plant 302 more accurately. When the elevator door panels 302 are normal and do not clamp the foreign matter 404, the rebound distance and the rebound speed are small, and when the foreign matter 404 is clamped between the elevator door panels 302, the rebound distance and the rebound speed are large due to large stress. If either the rebound velocity or the rebound distance exceeds the corresponding threshold, it can be determined whether the elevator door panel 302 has a foreign object 404 trapped therein. The first threshold may be a threshold of the rebound distance, the second threshold may be a threshold of the rebound speed, and the size of the threshold may be set according to an actual situation. The present embodiment can more accurately determine that a foreign object 404 is trapped between the elevator door panels 302 when one or both of the rebound distance or the rebound velocity exceeds the respective threshold by setting the respective distance threshold and velocity threshold and comparing the corresponding rebound distance and rebound velocity.
In one embodiment, before canceling the door closing torque of the elevator door motor to rebound the elevator door panel 302 when the elevator door panel 302 is detected to be fully closed, the method further comprises: sending a door closing signal to the elevator door motor to cause the elevator door motor to control the elevator door panel 302 to close; when the loop closure signal of the elevator car door lock is detected, it is determined that the elevator door panel 302 is fully closed.
In this embodiment, the door closing signal may be a signal for controlling the elevator door panel 302 to close the door by the elevator door controller, and the elevator door controller may control the elevator door panel 302 to close after receiving the signal. The elevator car door lock may be a door lock disposed on an elevator door panel 302. After elevator door plant 302 closed, the mechanical latch hook meshing of lock, the safety circuit of elevator is closed this moment, when elevator door plant 302 was opened, the value of encoder can be a value of setting for, when elevator door plant 302 was closed, the value of encoder can be another value of setting for, elevator door machine can judge whether elevator door plant 302 is closed completely through the value of encoder this moment, and can send elevator door complete closure signal to elevator master control when judging for complete closure, elevator master control can judge that elevator door plant 302 is complete closure state this moment, just can start the operation, can guarantee that the elevator operation is safer.
The present embodiment may also perform the step of canceling the door-closing moment after determining that the elevator is in the closed state, to check whether the foreign object 404 is caught on the lower portion of the elevator door panel 302 even though the elevator may be normally closed.
In one embodiment, obtaining the spring back distance and spring back velocity of the elevator door panel 302 comprises: first position information of a preset point of the elevator door panel 302 when the elevator door panel 302 rebounds to stop; determining a spring back velocity of the elevator door panel 302 from the second position to the first position; the second position information is the position information of a preset point when the elevator door panel 302 is completely closed; and obtaining the rebound distance of the elevator door panel 302 according to the first position information and the second position information.
In this embodiment, as shown in fig. 6, fig. 6 is a timing diagram illustrating an elevator rebounding process of the method for detecting a foreign object in an elevator door jam in one embodiment. The first position P1 information may be the position information of a preset point when the elevator door panel 302 returns to a vertical position during a rebound of the elevator. The second position P2 information may be the position information for a pre-set point when the elevator door motor has fully closed the elevator door panel 302 by applying a torque F1.
The rebound velocity can be obtained by recording the velocity of the preset point from the second position P2 to the first position P1 using an encoder in the elevator door. Wherein the preset point can be set on the elevator door panel 302, the rebound speed can be the highest speed between the second position P2 and the first position P1, or the average speed between the second position P2 and the first position P1, or the instantaneous speed at a certain moment between the second position P2 and the first position P1, and the specific mode can be set according to the actual situation.
The rebounding distance can be obtained by recording the distance from the second position P2 to the first position P1 by using an encoder in the elevator door machine, and it should be noted that, since the elevator door panel 302 may sway after reaching the first position P1 due to inertia during rebounding, the elevator door panel 302 may pass through the first position P1 multiple times during rebounding, and the first position P1 in this embodiment may be the position information when the preset point reaches the first position P1 for the first time.
In this embodiment, the elevator door panel 302 is closed by the elevator under the action of the moment F1, and at time t0, it can be determined that the elevator door panel 302 is closed, and at this time, the second position P2 information can be recorded. At time t0, i.e., the time when the elevator door panel 302 is fully closed, the elevator door motor can cancel the moment F1, so that the elevator door panel 302 rebounds, at time t1, the rebounding of the elevator door panel 302 is completed, and at this time, the encoder in the elevator door motor can record the first position P1 information. During rebound, the rebound velocity recorded by the encoder can be indicated by the segment 602, and the specific numerical form of the rebound velocity can be determined in any form in the segment 602. The rebound distance can be determined from the distance between the second position P2 and the first position P1 according to the preset point recorded by the encoder described above. Through this embodiment, above-mentioned encoder can confirm specific rebound velocity and rebound distance according to presetting some speed variation and the position change at the resilience in-process, can acquire rebound velocity and rebound distance more accurately for the encoder can judge more accurately whether elevator door plant 302 presss from both sides foreign matter 404.

Generally, the elevator door motor can be disposed at the upper part of the elevator, and thus, the device for detecting the preset point is also installed at the upper part of the elevator along with the elevator door motor, and at this time, the device can detect the position change of the upper part and the middle part of the elevator door panel 302, and thus, the preset point can be disposed at the upper part and/or the middle part of the elevator door panel 302. In some embodiments, the elevator door motor may be located at the bottom of the elevator, where the above-described device is also installed with the elevator door motor at the bottom of the elevator, where the device may detect a change in position at the bottom and/or middle of the elevator door panel 302, and thus the preset point may be located at the bottom and/or middle of the elevator door panel 302. The number of preset points is not limited.
In one embodiment, further comprising: if the elevator door panel 302 is determined to contain the foreign matter 404, an operation stop signal is sent to the elevator master control to stop the operation of the elevator.
