Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present invention, and the embodiments can be mutually combined and referred to without contradiction.
A first embodiment of the invention relates to an elevator foreign matter monitoring method. The specific flow is shown in figure 1.
And 101, setting a monitoring area of a visual light curtain according to the track change condition of the elevator door, wherein the length of the monitoring area is the length of an area where the elevator door is not closed, the width of the monitoring area is the width of a maximum monitoring area obtained by pre-calculation, and when the elevator door is completely opened, the monitoring area is the maximum monitoring area.
In the embodiment, the visual light curtain comprises a camera and a visual algorithm processor, wherein the camera is arranged at the middle position above the inner door lintel in the car; the visual light curtain is connected with the elevator controller through a communication bus; the elevator controller is connected with the door machine controller through a communication bus; the door operator controller controls the door operator as shown in fig. 2.
After the visual light curtain is installed, the elevator controller sends an instruction to the door machine through the door machine controller to control the elevator to keep the elevator door in a fully-opened state, and the visual light curtain processor records the state of the elevator door at the moment.
The elevator controller then performs a closing operation on the control elevator door via the door operator controller and at the same time informs the vision light curtain that this action is being performed. At the moment, the section of the landing door and the section of the car door are gradually increased, the track change condition is recorded by the visual light curtain, and the section of the effective monitoring area is formed through the track change. That is, the changed area is the boundary of the area to be monitored, and the vision algorithm processor forms a complete monitoring area, namely an effective monitoring area, according to the track change.
When the elevator door is in a fully opened state, the monitoring area is the largest, namely the largest monitoring area, and the monitoring area at the moment comprises the whole area of the elevator landing door, the clearance area between the elevator landing door and the elevator car door and the whole area of the elevator car door.
It should be noted that, there may be a small degree of asynchronism between the elevator landing door and the elevator car door during the door closing process, i.e. the door closing speeds of the elevator landing door and the elevator car door are not consistent. Two situations are distinguished:
first, the elevator car door is faster than the elevator landing door. The visual light curtain takes the change of the elevator car door as a main reference system, records the change track of the length and the width of the elevator car door in the process of closing the elevator door, and records the change track of the width of the elevator landing door in the dynamic process that the elevator car door is not completely closed; when the elevator car door is fully closed, the visual light curtain elevator door is informed that the elevator door is in a closed state. The visual light curtain automatically generates an effective monitoring area according to track changes of the elevator car door and the elevator landing door, wherein the middle clearance area between the elevator car door and the elevator landing door is not required to be independently recorded through dynamic tracks of the landing door and the elevator car door, and the visual light curtain is automatically supplemented by a visual light curtain algorithm. Specifically, the cross-sectional area of the effective monitoring area is the sum of the area of the entire area of the elevator car door (i.e., the length of the elevator car door track change) and the length of the elevator car door track change and the automatically generated gap area.
And secondly, the elevator landing door is faster than the elevator car door. The visual light curtain takes the change of the elevator landing door as a main reference system, records the change track of the length and the width of the elevator landing door in the process of closing the elevator landing door, and records the change track of the width of the elevator car door in the dynamic process that the elevator landing door is not completely closed; when the elevator landing door is fully closed, the visual light curtain is informed that the elevator door is already in a closed state. The visual light curtain automatically generates an effective monitoring area according to track changes of the elevator car door and the elevator landing door, wherein the middle clearance area between the elevator car door and the elevator landing door is not required to be independently recorded through dynamic tracks of the landing door and the elevator car door, and the visual light curtain is automatically supplemented by a visual light curtain algorithm. Specifically, the cross-sectional area of the effective monitoring area is the sum of the area of the elevator landing door in the whole area (namely the length of the elevator landing door change track is the width), the length of the elevator landing door track change is the width of the elevator car door track change and the automatically generated middle gap area.
The maximum monitoring area is obtained through the method.
When the elevator is in a door opening and closing state, the monitoring area of the foreign matters changes according to the track change condition of the elevator door, namely the length of the monitoring area is the length of the area where the elevator door is not closed, and the width of the monitoring area is the width of the maximum monitoring area obtained by pre-calculation.
When the elevator is in a fully opened state, the monitoring area is the maximum monitoring area.
It should be noted that there may be a case where the movement speeds of the elevator landing door and the elevator car door are not uniform. The length of the area which is not closed and has the faster moving speed of the elevator landing door and the elevator car door is taken as the length of the monitoring area.
Specifically, the following two cases are classified:
first, the elevator car door is faster than the elevator landing door. The visual light curtain takes the change of the elevator car door as a main reference system, and the visual light curtain synchronously narrows the effective defense area along with the gradual closing of the elevator car door, the length of the narrowing section depends on the length of the area which is not closed, and the width of the narrowing section is the width of the maximum monitoring area.
And secondly, the elevator landing door is faster than the elevator car door. The visual light curtain takes the change of the elevator landing door as a main reference system, and the visual light curtain synchronously narrows the effective defense area along with the gradual closing of the elevator landing door, the length of the narrowing section depends on the length of the area which is not closed, and the width of the narrowing section is the width of the maximum monitoring area.
And 102, when foreign matters enter the monitoring area, controlling the elevator door to be opened.
And monitoring the obtained monitoring area, and when the foreign matters enter the monitoring area, sending a message to the elevator controller by the visual light curtain, and then sending a door opening instruction to the door machine controller by the elevator controller so as to control the elevator door to be opened.
When no foreign matter exists in the monitoring area, the visual light curtain sends a message to the elevator controller, and the elevator controller sends a door closing instruction to the door machine controller, so that the elevator door is controlled to be closed.
The foreign matter can be a person or an article, and the vision algorithm processor automatically identifies the type of the foreign matter and determines that the foreign matter needs to be subjected to door opening operation.
Compared with the related art, the embodiment of the invention dynamically adjusts the monitoring area according to the track change of the elevator door, so that the demarcation range of the monitoring area can be changed along with the change of the elevator door, and the setting of the monitoring area is more accurate. Meanwhile, the maximum monitoring area is obtained through precalculation based on the change of the maximum monitoring area, so that the setting of the maximum monitoring area is more accurate, and the setting of the monitoring area based on the change of the maximum monitoring area is further more accurate.
A second embodiment of the invention relates to an elevator foreign matter monitoring method. In the present embodiment, taking a top view of the visual light curtain system car shown in fig. 3 as an example, A1 and A2 are left and right door cross-sectional areas of an elevator landing door; a3, elevator landing sill blank area; b is a gap area between an elevator landing door and an elevator car door; c1 and C2 are left and right door section areas of the elevator car door, and C3 is a sill blank area of the elevator car door; d is a foreign matter.
After the visual light curtain is installed, the elevator controller sends an instruction to the door machine through the door machine controller to control the elevator to keep the elevator door in a fully-opened state, the areas of A1, A2, C1 and C2 are all 0 at the moment, and the visual light curtain processor records the state of the elevator door at the moment.
The elevator controller then performs a closing operation on the control elevator door via the door operator controller and at the same time informs the vision light curtain that this action is being performed. At this time, landing door sections A1 and A2 and car door sections C1 and C2 are gradually increased, the track change is recorded by the visual light curtain, and an effective monitoring area section is formed by the track change. That is, the changed area is the boundary of the area to be monitored, and the vision algorithm processor forms a complete monitoring area, namely an effective monitoring area, according to the track change.
The monitoring area is the largest, i.e. the largest monitoring area when the elevator door is in the fully open state, the monitoring area at this time comprising a1+a2+a3, B and c1+c2+c3.
It should be noted that, there may be a small degree of asynchronism between the elevator landing door and the elevator car door during the door closing process, i.e. the door closing speeds of the elevator landing door and the elevator car door are not consistent. Two situations are distinguished:
first, the elevator doors C1, C2 are faster than the elevator landing doors A1, A2. The visual light curtain takes the changes of C1 and C2 as a main reference system, records the change tracks of the length and the width of C1 and C2 in the process of closing the elevator door, and records the change tracks of A1 and A2 in the dynamic process of not completely closing the elevator car door; when c3=0, the visual light curtain elevator door is informed that it is already in a closed state. The visual light curtain automatically generates an effective monitoring area according to track changes of the elevator car door and the elevator landing door, wherein the area B is not required to be independently recorded through dynamic tracks of the landing door and the car door, and is automatically supplemented by a visual light curtain algorithm. Specifically, the cross-sectional area of the effective monitoring area is the sum of the lengths of the c1+c2+c3, C1, and C2 track changes, the widths of the A1 and A2 track changes, and the area of the automatically generated B area.
Secondly, the elevator landing doors A1, A2 are faster than the elevator car doors C1, C2. The visual light curtain takes the changes of A1 and A2 as a main reference system, records the change tracks of the length and the width of A1 and A2 in the process of closing the elevator door, and records the change tracks of C1 and C2 in the dynamic process of not completely closing the elevator car door; when a3=0, the visual light curtain elevator door is informed that it is already in a closed state. The visual light curtain automatically generates an effective monitoring area according to track changes of the elevator car door and the elevator landing door, wherein the area B is not required to be independently recorded through dynamic tracks of the landing door and the car door, and is automatically supplemented by a visual light curtain algorithm. Specifically, the cross-sectional area of the effective monitoring area is the sum of the widths of the a1+a2+a3, A1, and A2 track changes and the automatically generated B area.
The maximum monitoring area is obtained through the method.
When the elevator is in a door opening and closing state, the monitoring area of the foreign matters changes according to the track change condition of the elevator door, namely the length of the monitoring area is the length of the area where the elevator door is not closed, and the width of the monitoring area is the width of the maximum monitoring area obtained by pre-calculation.
When the elevator is in a fully opened state, the monitoring area is the maximum monitoring area.
It should be noted that there may be a case where the movement speeds of the elevator landing door and the elevator car door are not uniform. The length of the area which is not closed and has the faster moving speed of the elevator landing door and the elevator car door is taken as the length of the monitoring area.
Specifically, the following two cases are classified:
first, the elevator doors C1, C2 are faster than the elevator landing doors A1, A2. The visual light curtain takes the changes of C1 and C2 as a main reference system, and the visual light curtain synchronously narrows the effective defense arrangement area along with the gradual increase of the sections of the car doors C1 and C2, the length of the narrowed section depends on the length of C3, and the width of the narrowed section is the width of the maximum monitoring area.
Secondly, the elevator landing doors A1, A2 are faster than the elevator car doors C1, C2. The visual light curtain takes the change of A1 and A2 as a main reference system, and the visual light curtain synchronously narrows the effective defense arrangement area along with the gradual increase of the sections of the landing doors A1 and A2, the length of the narrowed section depends on the length of A3, and the width of the narrowed section is the width of the maximum monitoring area.
Compared with the related art, the embodiment of the invention dynamically adjusts the monitoring area according to the track change of the elevator door, so that the demarcation range of the monitoring area can be changed along with the change of the elevator door, and the setting of the monitoring area is more accurate. Meanwhile, the maximum monitoring area is obtained through precalculation based on the change of the maximum monitoring area, so that the setting of the maximum monitoring area is more accurate, and the setting of the monitoring area based on the change of the maximum monitoring area is further more accurate.
