Description
Technical Field
[0001] This application belongs to the technical field of rail transit, and specifically relates to a subway platform screen door test bench. Background Art
[0002] A subway platform screen door is a device installed at the edge of a subway platform, used to isolate the platform area from the track area, ensuring passenger safety and optimizing the waiting environment.
[0003] For each subway line equipped with subway platform screen doors, a set of sample doors needs to be provided. First, the sample doors are used to provide technical training for employees on the control system and mechanical system of the subway platform screen doors. Second, the most important function of the subway platform screen doors is to ensure passenger safety. Therefore, the safety requirements for subway platform screen doors are extremely high. Therefore, before the electrical equipment such as PEDC and DCU and mechanical components in the control system supplied by the supplier are put into operation, they need to complete the function and quality tests of the control system and mechanical components through the sample doors in advance. Third, during the long-term use process, the control system of the subway platform screen doors will inevitably malfunction. Generally, the fault location cannot be eliminated on-site. Usually, the electrical and mechanical components of the control system that may have problems are disassembled and simulated tests are carried out through the sample doors for fault review to find out the causes of the faults and reduce the fault occurrence rate.
[0004] Generally, the sample doors include a set of control system, door machine system, fixed doors, sliding doors, and emergency doors. Taking the full-height platform screen doors as an example, the sliding doors on the door machine system are 2m high and 1m wide. Therefore, the net width of the two sliding doors is 2m and the height is 2m; plus the door machine part, the overall height is about 3m and the width is at least 5m; the weight of a single sliding door is about 110kg. Therefore, it is impossible to move the sample doors to the office for training, mechanical system and control system testing, and fault review.
[0005] Therefore, a subway platform screen door test bench is provided to simulate the door machine system of the sample doors. Summary of the Invention

[0027] By means of the above technical solutions, the invention of the present application has at least the following beneficial effects:
[0028] An embodiment of the present application provides a subway platform screen door test bench. The drive transmission system provides a power source for the entire system, and the control system is used to control the drive transmission system and the electromagnetic lock. The first situation: Before the door opens, the left traction suspension device and the right traction suspension device are in a closed and locked state with the electromagnetic lock. At this time, the left traction suspension device and the right traction suspension device are located at the initial position; the upper traction suspension device and the right traction suspension device are linked by a belt, and their movement directions are opposite. Therefore, the upper traction suspension device is located at the initial position, and the follower device is also located at the initial position; the left traction suspension device has a tendency to move in the first direction under the pulling force of the tension spring. Since the follower device and the left traction suspension device are linked by a pull rod, the follower device also has a tendency to move in the first direction; therefore, under the action of the tension spring, the follower device is in close contact with the upper traction suspension device; when the door opens, the electromagnetic lock is first unlocked, and the drive transmission system drives the right traction suspension device to move from the initial position in the second direction. Since the upper traction suspension device and the right traction suspension device are linked by a belt and their movement directions are opposite, the upper traction suspension device is simultaneously driven to move from the initial position in the first direction; at this time, under the pulling force of the tension spring, the left traction suspension device moves from the initial position in the first direction. At this time, under the action of the pull rod, the follower device moves synchronously with the left traction suspension device. When the left traction suspension device moves 40 mm in the first direction and stops moving at the target position, the follower device also reaches the target position. The upper traction suspension device continues to move 960 mm in the first direction until the right traction suspension device moves 1000 mm to the target position, and at this time, the upper traction suspension device also reaches the target position. The closing action is opposite to the opening action. Before closing the door, the left traction suspension device, the right traction suspension device, the upper traction suspension device, and the follower device are all located at the target position; when closing the door, the electromagnetic lock is still in the unlocked state, and the drive transmission system drives the right traction suspension device to move from the target position in the first direction, and at the same time, the upper traction suspension device moves from the target position in the second direction; when the upper traction suspension device moves 960 mm in the second direction and contacts the follower device, and pushes the follower device to move from the target position in the second direction. Under the action of the pull rod, the left traction suspension device moves 40 mm from the target position to the initial position and closes and locks with the electromagnetic lock. At this time, the right traction suspension device moves 1000 mm in the first direction to the initial position and closes and locks with the electromagnetic lock.
[0029] The second case: The difference between the second case and the first case is that the tension spring is replaced by an electromagnet. Before closing the door, the left traction suspension device, the right traction suspension device, the upper traction suspension device and the follow-up device are all in the target position. When closing the door, the drive transmission system drives the right traction suspension device to move from the target position in the first direction, and at the same time drives the upper traction suspension device to move from the target position in the second direction. When the upper traction suspension device moves 960 mm and triggers the first optoelectronic switch, the coil of the electromagnet is de-energized. At this time, the upper traction suspension device contacts the follow-up device and pushes the follow-up device to move from the target position in the second direction. Under the action of the pull rod, the left traction suspension device is pushed to move 40 mm from the target position in the second direction to the initial position and closes and locks with the electromagnetic lock. At the same time, the right traction suspension device moves 1000 mm in the first direction to close and lock with the electromagnetic lock. At the last moment of closing the door, when the upper traction suspension device triggers the second optoelectronic switch, the trigger control circuit is maintained and the coil of the electromagnet is energized to prepare for opening the door. Before opening the door, the left traction suspension device, the right traction suspension device, the upper traction suspension device and the follow-up device are all in the initial position. When opening the door, since the electromagnet coil is in the energized state, the follow-up device is attracted to the upper traction suspension device at this time. The electromagnetic lock is unlocked first. The drive transmission system drives the right traction suspension device to move from the initial position in the second direction, and at the same time drives the upper traction suspension device to move from the initial position in the first direction. The electromagnet generates magnetic force to pull the follow-up device to move in the first direction from the initial position along with the upper traction suspension device. Under the action of the pull rod, the follow-up device pushes the left traction suspension device to move in the first direction from the initial position. When the upper traction suspension device triggers the first optoelectronic switch, the trigger control circuit makes the coil voltage on the electromagnet zero. At this time, the electromagnetic attraction force is zero and the follow-up device stops moving. At this time, both the left traction suspension device and the follow-up device have moved 40 mm and remain in the target position. The upper traction suspension device continues to move 960 mm in the first direction to reach the target position, and at the same time the right traction suspension device moves 1000 mm in the second direction to the target position.
[0030] The subway platform screen door test bench of this application is lighter in weight and smaller in size than the sample door; at the same time, it has functions such as employee training, mechanical system and control system testing, and fault review of the mechanical parts of the control system electrical.

[0063] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0064] Refer to Figures 1 to 13 As shown, according to Embodiment 1 of the present application, a subway platform screen door test bench is provided, including a support system, a left traction suspension device 2, a right traction suspension device 3, an electromagnetic lock 4, a follow-up device 5, an upper traction suspension device 6, a pull rod 7, a spring 801, a drive transmission system, and a control system;
[0065] The support system includes a bench assembly 11 and a base assembly 12. The bench assembly 11 is detachably arranged on the base assembly 12. The left traction suspension device 2 is arranged on the bench assembly 11 and slides relative to the bench assembly 11. The right traction suspension device 3 is arranged on the bench assembly 11 and slides relative to the bench assembly 11. The electromagnetic lock 4 is installed on the bench assembly 11 and is located on one side of the bench assembly 11. The left traction suspension device 2 and the right traction suspension device 3 are arranged on both sides of the electromagnetic lock 4. The follow-up device 5 is arranged on the bench assembly 11 and is located on the other side of the bench assembly 11. The follow-up device 5 slides relative to the bench assembly 11. The upper traction suspension device 6 is arranged on the bench assembly 11 and slides relative to the bench assembly 11. When the left traction suspension device 2 and the right traction suspension device 3 are closed and locked with the electromagnetic lock 4, the upper traction suspension device 6 abuts against the follow-up device 5. The pull rod 7 includes a first end and a second end. The left traction suspension device 2 is connected to the first end of the pull rod 7, and the follow-up device 5 is connected to the second end of the pull rod 7. When the left traction suspension device 2 is pulled by the tension spring 801, one end of the tension spring 801 is connected to the left traction suspension device 2, and the other end is connected to the base assembly 12. The drive transmission system is arranged on the bench assembly 11. The right traction suspension device 3 and the upper traction suspension device 6 are connected to the drive transmission system. The drive transmission system is used to drive the right traction suspension device 3 and the upper traction suspension device 6 to slide along the bench assembly 11. The drive transmission system and the electromagnetic lock 4 are electrically connected to the control system. The control system is used to control the opening and closing of the drive transmission system and the electromagnetic lock 4.
[0066] The subway platform screen door test bench of this application is lighter in weight and smaller in size compared to the sample door. At the same time, it has functions such as employee training, mechanical system and control system testing, and fault review of the mechanical components of the control system electrical.
[0067] Among them, the detachable connection is a bolt connection in this embodiment. In other embodiments, it can be adjusted according to the specific assembly situation and can be a snap connection, a plug connection, etc.
[0068] Among them, the support system includes a bench assembly 11 and a base assembly 12. The bench assembly 11 is detachably arranged on the base assembly 12. Here, the support system further includes a base connecting plate 13. The base system 12 is used to support the upper structure. The bench assembly 11 is vertically arranged relative to the base assembly 12, and the ends of the two are tightened through the base connecting plate 13 and bolts to fix the bench assembly 11 on the base assembly 12.
[0069] Specifically, the base connecting plate 13 is a T-shaped structural plate. The base connecting plate 13 includes a bottom plate and a vertical plate. The bottom plate is connected to the end of the base assembly 12 by bolts, and the vertical plate is connected to the end of the bench assembly 11 by bolts to realize the connection between the bench assembly 11 and the base assembly 12. That is to say, the bench assembly 11 and the base assembly 12 are of a split structure. On the one hand, since the bench assembly 11 is vertically arranged on the base assembly 12 and the two form an inverted T-shaped structure, if they are connected by welding, the parts are prone to deformation during the welding process, and it is very difficult to ensure the geometric tolerance and dimensional tolerance. Therefore, the bench assembly 11 and the base assembly 12 are connected in a split manner. On the other hand, the bench assembly 11 and the base assembly 12 are of a split type, which has strong versatility and is convenient for handling.
[0070] Specifically, the base assembly 12 includes a quadrilateral frame 1201 and a cushion block 1202. The cushion block 1202 is arranged at the top of the short side of the quadrilateral frame 1201. During installation, the end of the bench assembly 11 is seated on the cushion block 1202, and it is ensured that the ends of the bench assembly 11 and the base assembly 12 are flush, which is convenient for subsequent tightening and fixing at the ends. At the same time, by setting the cushion block 1202, a height difference is formed between the bench assembly 11 and the base assembly 12, so as to facilitate the installation of other components on the bench assembly 11.
[0071] Specifically, the base assembly 12 further includes anchor bolts 1203. The anchor bolts 1203 are symmetrically installed on the long sides of the quadrilateral frame 1201. By adjusting the height of the anchor bolts 1203, the quadrilateral frame 1201 is made horizontal, that is to say, the subway platform screen door test bench is made horizontal.
[0072] Among them, the left traction suspension device 2 slides relative to the bench assembly 11; the right traction suspension device 3 is arranged on the bench assembly 11 and slides relative to the bench assembly 11; the electromagnetic lock 4 is installed on the bench assembly 11 and is located on one side of the bench assembly 11; the left traction suspension device 2 and the right traction suspension device 3 are arranged on both sides of the electromagnetic lock 4; here, the right traction suspension device 3 is arranged on the bench assembly 11 and slides relative to the bench assembly 11; that is to say, the opening and closing actions of the two sliding doors of the sample door are simulated through the right traction suspension device 3 and the left traction suspension device 2. Here, the stroke of the right traction suspension device 3 is large and the stroke of the left traction suspension device 2 is small by means of overtravel. Therefore, the size of the subway platform screen door test bench is much smaller than that of the sample door, so that the work of employee training, mechanical system and control system testing, and fault review of the mechanical parts of the control system electrical can be carried out in the laboratory; the left traction suspension device 2 and the right traction suspension device 3 are arranged on both sides of the electromagnetic lock 4, that is to say, the left traction suspension device 2 and the right traction suspension device 3 are simultaneously closed and locked by the electromagnetic lock 4, or the left traction suspension device 2 and the right traction suspension device 3 are simultaneously unlocked on the electromagnetic lock 4.
[0073] Among them, the follow-up device 5 is arranged on the bench assembly 11 and is located on the other side of the bench assembly 11; the follow-up device 5 slides relative to the bench assembly 11; the pull rod 7 includes a first end and a second end. The left traction suspension device 2 is connected to the first end of the pull rod 7, and the follow-up device 5 is connected to the second end of the pull rod 7. Here, the follow-up device 5 is located at the top of the bench assembly 11 and slides relative to the bench assembly 11. That is to say, the follow-up device 5 only has a sliding degree of freedom relative to the bench assembly 11; the follow-up device 5 and the left traction suspension device 2 are connected through the pull rod 7. That is to say, when opening the door, the left traction suspension device 2 moves in the first direction, and at the same time, the follow-up device 5 is pulled along the first direction through the pull rod 7 to open the door; when closing the door, the upper traction suspension device 6 moves in the first direction to push the follow-up device 5 to move along the second direction together. At this time, under the traction of the pull rod 7, the left traction suspension device 2 also moves along the second direction together to close the door. Therefore, the synchronous movement of the left traction suspension device 2 and the follow-up device 5 is realized through the pull rod 7.
[0074] Among them, the upper traction suspension device 6 is arranged on the bench assembly 11 and slides relative to the bench assembly 11; here, the upper traction suspension device 6 is arranged closer to the electromagnetic lock 4 than the follow-up device 5. When closing and opening the door, the upper traction suspension device 6 and the right traction suspension device 3 are both driven by the same power source to realize the synchronous movement of the two.
[0075] Among them, when the left traction suspension device 2 is pulled by the tension spring 801, one end of the tension spring 801 is connected to the left traction suspension device 2, and the other end is connected to the base assembly 12; the tension spring 801 is used to pull the left traction suspension device 2 to move.
[0076] Specifically, when the left traction suspension device 2 is pulled by the tension spring 801, at this time, a first angle bracket is installed on the inner side wall of the wide side of the base assembly 12, that is to say, the first angle bracket is opposite to the base connecting plate 13. At this time, the first angle bracket and the base connecting plate 13 share the same bolt connection.

[0119] When the left traction suspension device 2 is pulled by the tension spring 801, before the door is opened, the left traction suspension device 2 and the right traction suspension device 3 are in a closed and locked state with the electromagnetic lock 4. At this time, the left traction suspension device 2 and the right traction suspension device 3 are located at the initial positions; the upper traction suspension device 6 and the right traction suspension device 3 are linked by a belt 901, and their moving directions are opposite. Therefore, the upper traction suspension device 6 is located at the initial position, and similarly, the follower device 5 is also located at the initial position; the left traction suspension device 2 has a tendency to move in the first direction under the pulling force of the tension spring 801. Since the follower device 5 and the left traction suspension device 2 are linked by a pull rod 7, the follower device 5 also has a tendency to move in the first direction; therefore, under the action of the tension spring 801, the follower device 5 is in close contact with the upper traction suspension device 6; when the door is opened, the controller of the control system controls the electromagnetic lock 4 to be powered on and unlocked, and then powered off; the controller of the control system controls the driving motor 909 to start. The belt 901 moves counterclockwise under the drive of the driving motor 909, driving the right traction suspension device 3 to move from the initial position in the second direction. Since the upper traction suspension device 6 and the right traction suspension device 3 are linked by the belt 901 and their moving directions are opposite, the upper traction suspension device 6 is simultaneously driven to move from the initial position in the first direction; at this time, under the pulling force of the tension spring 801, the left traction suspension device 2 moves from the initial position in the first direction. At this time, under the action of the pull rod 7, the follower device 5 moves synchronously with the left traction suspension device 2. When the left traction suspension device 2 moves 40 mm in the first direction and stops moving at the target position, the follower device 5 also reaches the target position at this time. The upper traction suspension device 6 continues to move 960 mm in the first direction until the right traction suspension device 3 moves 1000 mm to the target position. At this time, the upper traction suspension device 6 also reaches the target position. The closing action is opposite to the opening action.
[0120] Embodiment 2
[0121] The difference between Embodiment 2 and Embodiment 1 is that the left traction suspension device 2 is pulled by an electromagnet 802.
[0122] Referring to Figures 14 to 19 As shown, according to Embodiment 2 of the present application, a subway platform screen door test bench is provided, including a support system, a left traction suspension device 2, a right traction suspension device 3, an electromagnetic lock 4, a follower device 5, an upper traction suspension device 6, a pull rod 7, an electromagnet 802, a drive transmission system, and a control system;
[0123] The support system includes a bench assembly 11 and a base assembly 12. The bench assembly 11 is detachably arranged on the base assembly 12; a left traction suspension device 2 is arranged on the bench assembly 11 and slides relative to the bench assembly 11; a right traction suspension device 3 is arranged on the bench assembly 11 and slides relative to the bench assembly 11; an electromagnetic lock 4 is installed on the bench assembly 11 and is located on one side of the bench assembly 11; the left traction suspension device 2 and the right traction suspension device 3 are arranged on both sides of the electromagnetic lock 4; a follow-up device 5 is arranged on the bench assembly 11 and is located on the other side of the bench assembly 11; the follow-up device 5 slides relative to the bench assembly 11; an upper traction suspension device 6 is arranged on the bench assembly 11 and slides relative to the bench assembly 11; when the left traction suspension device 2 and the right traction suspension device 3 are closed and locked with the electromagnetic lock 4, the upper traction suspension device 6 abuts against the follow-up device 5; the pull rod 7 includes a first end and a second end. The left traction suspension device 2 is connected to the first end of the pull rod 7, and the follow-up device 5 is connected to the second end of the pull rod 7; when the left traction suspension device 2 is pulled by an electromagnet 802, the electromagnet 802 is arranged on the top of the follow-up device 5; the electromagnet 802 is used to pull the left traction suspension device 2 to move; a drive transmission system is arranged on the bench assembly 11. The right traction suspension device 3 and the upper traction suspension device 6 are connected to the drive transmission system. The drive transmission system is used to drive the right traction suspension device 3 and the upper traction suspension device 6 to slide along the bench assembly 11; the drive transmission system and the electromagnetic lock 4 are electrically connected to a control system. The control system is used to control the opening and closing of the drive transmission system and the electromagnetic lock 4.
[0124] Specifically, when the left traction suspension device 2 is pulled by the electromagnet 802, at this time, the electromagnet 802 is installed on the side wall of the follow-up device 5. In order to ensure the stable attraction between the follow-up device 5 and the upper traction suspension device 6 under the action of magnetic force, a soft iron component 803 needs to be installed at one end of the upper traction suspension device 6 facing the follow-up device 5. The electromagnet 802 is energized to generate magnetic force and attracts the soft iron component 803, so that the follow-up device 5 is attracted to the upper traction suspension device 6; at the same time, a photoelectric switch is installed on the top side wall of the bench assembly 11, and a light shielding plate is installed on the side of the upper traction suspension device 6 facing the photoelectric switch. The photoelectric switch is triggered by the light shielding plate to control the power on and off of the electromagnet 802.
[0125] When using the electromagnet 802, it can overcome the problem that the resistance of the driving part of the drive transmission system itself increases when using a tension spring 801.
[0126] More specifically, there are two photoelectric switches, namely a first photoelectric switch 804 and a second photoelectric switch 805, and the first photoelectric switch 804 is arranged farther away from the follow-up device 5 than the second photoelectric switch 805.
[0127] At the last moment of closing the door, the light shield on the upper traction suspension device 6 triggers the second photoelectric switch 805, and the electromagnet 802 is energized to prepare for opening the door; when opening the door, since the coil of the electromagnet 802 is in the energized state, at this time the follower device 5 is attracted to the upper traction suspension device 6; the electromagnetic lock 4 is first unlocked, and the drive transmission system drives the right traction suspension device 3 to move along the second direction from the initial position, and at the same time drives the upper traction suspension device 6 to move along the first direction from the initial position. The electromagnet 802 generates a magnetic force to pull the follower device 5 to move along the first direction from the initial position together with the upper traction suspension device 6. Under the action of the pull rod 7, the follower device 5 pushes the left traction suspension device 2 to move along the first direction from the initial position. When the upper traction suspension device 6 triggers the first photoelectric switch 804, the control circuit is triggered to make the coil voltage on the electromagnet 802 zero. At this time, the suction force of the electromagnet 802 is zero, and the follower device 5 stops moving. At this time, both the left traction suspension device 2 and the follower device 5 have moved 40 mm and remain at the target position; while the upper traction suspension device 6 continues to move 960 mm along the first direction to reach the target position, and at the same time the right traction suspension device 3 moves 1000 mm along the second direction to the target position.
[0128] Among them, the drive transmission system and the electromagnetic lock 4 are electrically connected to the control system, and the control system is used to control the opening and closing of the drive transmission system and the electromagnetic lock 4. The control system includes a controller and a power supply. The controller is the core component of the entire control system and is used to send and receive control signals to adjust the start and stop of the drive rotation system and to adjust the locking and unlocking of the electromagnetic lock 4; the power supply is used to supply power to the entire control system, the drive transmission system, and the electromagnetic lock 4.
[0129] A more specific working process is as follows:
[0130] Before closing the door, the left traction suspension device 2, the right traction suspension device 3, the upper traction suspension device 6, and the follower device 5 are all at the target position; when closing the door, the electromagnetic lock 4 is still in the unlocked state, and the belt 901 rotates clockwise under the drive of the drive motor 909, driving the right traction suspension device 3 to move along the first direction from the target position, and at the same time the upper traction suspension device 6 moves along the second direction from the target position; when the upper traction suspension device 6 moves 960 mm along the second direction and contacts the follower device 5, and pushes the follower device 5 to move along the second direction from the target position. Under the action of the pull rod 7, the left traction suspension device 2 moves 40 mm from the target position to the initial position and closes and locks with the electromagnetic lock 4. At this time, the right traction suspension device 3 moves 1000 mm in the first direction to the initial position and closes and locks with the electromagnetic lock 4.
[0131] When the left traction suspension device 2 is pulled by the electromagnet 802, before closing the door, the left traction suspension device 2, the right traction suspension device 3, the upper traction suspension device 6 and the follower device 5 are all in the target positions; when closing the door, the belt 901 moves clockwise under the drive of the drive motor 909, driving the right traction suspension device 3 to move from the target position in the first direction, and at the same time driving the upper traction suspension device 6 to move from the target position in the second direction. When the upper traction suspension device 6 moves 960 mm and triggers the first optoelectronic switch 804, the coil of the electromagnet 802 is de-energized. At this time, the upper traction suspension device 6 contacts the follower device 5 and pushes the follower device 5 to move from the target position in the second direction. Under the action of the pull rod 7, the left traction suspension device 2 is pushed to move 40 mm from the target position in the second direction to the initial position and is closed and locked with the electromagnetic lock 4. At the same time, the right traction suspension device 3 moves 1000 mm in the first direction to be closed and locked with the electromagnetic lock 4; at the last moment of closing the door, when the upper traction suspension device 6 triggers the second optoelectronic switch 805, the trigger control circuit is maintained and the coil of the electromagnet 802 is energized to prepare for opening the door; before opening the door, the left traction suspension device 2, the right traction suspension device 3, the upper traction suspension device 6 and the follower device 5 are all in the initial positions; when opening the door, since the coil of the electromagnet 802 is in the energized state, at this time the follower device 5 is attracted to the upper traction suspension device 6; the controller of the control system controls the electromagnetic lock 4 to be unlocked by energization; the drive system controller controls the drive motor 909 to drive the belt to move counterclockwise, driving the right traction suspension device 3 to move from the initial position in the second direction, and at the same time driving the upper traction suspension device 6 to move from the initial position in the first direction. The electromagnet 802 generates a magnetic force to pull the follower device 5 to move in the first direction together with the upper traction suspension device 6 from the initial position. Under the action of the pull rod 7, the follower device 5 pushes the left traction suspension device 2 to move from the initial position in the first direction. When the upper traction suspension device 6 triggers the first optoelectronic switch 804, the trigger control circuit makes the coil voltage on the electromagnet 802 zero. At this time, the suction force of the electromagnet 802 is zero and the follower device 5 stops moving. At this time, both the left traction suspension device 2 and the follower device 5 have moved 40 mm and remain in the target positions; while the upper traction suspension device 6 continues to move 960 mm in the first direction to reach the target position, and at the same time the right traction suspension device 3 moves 1000 mm in the second direction to the target position.
[0132] Here, the initial position is the position where the left traction suspension device 2, the right traction suspension device 3, the upper traction suspension device 6 and the follower device 5 are located in the closed door state; the target position is the position where the left traction suspension device 2, the right traction suspension device 3, the upper traction suspension device 6 and the follower device 5 are located in the open door state.
