Detailed Description

Various embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Here, it is to be noted that, in the drawings, the same reference numerals are given to constituent parts having substantially the same or similar structures and functions, and repeated description thereof will be omitted. The term "sequentially comprising A, B, C, etc" merely indicates the order of the included elements A, B, C, etc. and does not exclude the possibility of including other elements between a and B and/or between B and C.

The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of respective portions and their mutual relationships.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to fig. 1 to 11.

The monitoring system according to the invention is used for monitoring people conveying equipment. In the following description, the monitoring system is described by way of example with an escalator, but it will be clear to a person skilled in the art that the monitoring system of the invention can also be applied to other people conveyor installations, such as travelators or the like.

The monitoring system comprises a support 1 arranged on the people conveyor, preferably between the guardrail and the outer edge of the people conveyor, and a detection device 2. The support has an overhanging portion 11 located above the step, and the detection means is disposed within the overhanging portion, as shown in figures 1 and 2.

The detection device 2 comprises a fixing member 21 mounted in the overhanging portion; a first camera 22 and a second camera 23, each pivotally mounted to the mount, able to pivot about the mount. The first camera 22 is pivotably mounted to the mount via a first mount 24 such that pivoting the first mount 24 about the mount causes the first camera 22 to pivot within a first predetermined angular range, which may be selected as desired, to adjust the viewing range of the first camera. Similarly, the second camera is pivotably mounted to the mount via a second mount 25, such that pivoting the second mount 25 about the mount causes the second camera 23 to pivot within a second predetermined angular range, which may be selected as desired, to adjust the viewing range of the second camera.

The first camera and the second camera may be arranged in the front-rear direction or in the left-right direction, which generally depends on the size of the cameras, and may be arranged in different ways for convenience of arranging the cameras of different sizes. In this context, "front-back direction" refers to a direction perpendicular to the longitudinal axis of the fixing member, and "left-right direction" refers to a direction parallel to the longitudinal axis of the fixing member.

The first camera and the second camera are arranged such that an optical axis of a lens of the first camera and an optical axis of a lens of the second camera are at an angle to each other such that the first camera and the second camera are arranged toward the front-rear direction, respectively. Preferably, the optical axis of the lens of the first camera and the optical axis of the lens of the second camera are located on both sides of a vertical axis, which may extend perpendicular to the overhanging portion, preferably symmetrical to each other.

Taking the mount as an example, as shown in fig. 5, the first camera and the second camera are arranged such that the optical axis O1 of the lens of the first camera and the optical axis O2 of the lens of the second camera are located on both sides of a vertical axis L 'perpendicular to the longitudinal axis L of the mount, and are each inclined with respect to the vertical axis L', so that the angle between the optical axis of the lens of the first camera and the optical axis of the lens of the second camera by pivoting of the first camera and the second camera varies within a predetermined range, for example, 30 degrees to 120 degrees. The "optical axis" is to be understood as the center line of all light beams passing through the center of the camera lens. That is, the angle between the optical axis of the lens of the first camera and the optical axis of the lens of the second camera is 120 degrees at the maximum (as shown in fig. 11) and 30 degrees at the minimum (as shown in fig. 10). In the case where other fixing parts are used without using a fixing member, those skilled in the art will appreciate that the arrangement of the first camera and the second camera may be changed as needed so that the optical axis of the lens of the first camera and the optical axis of the lens of the second camera can be arranged toward the front-rear direction, respectively.

The observation ranges of the first and second cameras partially overlap to form an overlap region S having a height in the vertical direction that is greater than the height of the observed object, as schematically shown in fig. 11.

Advantageously, as shown in fig. 3, the center line of the lens of the first camera and the center line of the lens of the second camera are both symmetrical to the center line of the steps in the running direction. Here, "center line" is understood to be a line passing through the center of the camera lens in a plan view.

The first mount 24 has a first portion 241 and a second portion 242, the first portion 241 being pivotably mounted to the fixture 21, e.g., the first portion having a first through-hole through which the fixture is configured to pass such that the first portion is pivotably mounted to the fixture. The first camera 22 is fixedly mounted to the second portion 242, the first portion being at a first angle α relative to a vertical axis L' perpendicular to the longitudinal axis L of the fixture, and the second portion being at a second angle β relative to the vertical axis perpendicular to the longitudinal axis L of the fixture, the first angle being greater than the second angle. That is, the second portion is "steeper" than the first portion.

In order to pivot the first portion (and thus the first camera) relative to the mount, a plurality of first grooves 211 are provided on the mount and the first resilient member 26 is provided in the first mount 24 such that the first resilient member 26 engages in one of the plurality of first grooves when the first mount is mounted to the mount. As such, when an external force is applied to pivot the first camera, the first elastic member 26 can be disengaged from one of the plurality of first grooves, which are spaced apart from each other by a predetermined angle (e.g., a range of 10 ° to 15 °), and then engaged in the other groove, so that the first mount can pivot within a first predetermined angle range. For example, the first resilient member 26 includes a first spring 261 and a first ball 262 configured to bias the first ball into abutment with one of the plurality of first grooves when the first mount is mounted to the fixture. The form of the first elastic member is not limited thereto as long as the purpose thereof can be achieved.

The manner in which the first portion is pivoted relative to the mount has been described above, and it will be understood by those skilled in the art that the present invention is not limited to the above manner, and is within the scope of the present invention, as long as it is possible to achieve pivoting of the first camera relative to the mount within a predetermined range.

Similarly, the second mount 25 has a third portion pivotally mounted to the fixture and a fourth portion, e.g., the third portion has a second through hole through which the fixture is configured to pass such that the third portion is pivotally mounted to the fixture. The second camera is fixedly mounted to a fourth portion, the third portion forming a third angle with respect to a vertical axis L' perpendicular to the longitudinal axis of the fixture, the fourth portion forming a fourth angle with respect to a vertical axis perpendicular to the longitudinal axis of the fixture, the third angle being greater than the fourth angle. That is, the fourth portion is "steeper" than the third portion.

Preferably, the third angle is the same as the first angle and the fourth angle is the same as the second angle. However, the third angle may be different from the first angle, and the fourth angle may be different from the second angle.

In order to pivot the third portion (and thus the second camera) relative to the mount, a plurality of second grooves are provided on the mount and a second resilient member is provided in the second mount such that the second resilient member engages in one of the plurality of second grooves when the second mount is mounted to the mount. As such, when an external force is applied to pivot the second camera, the second elastic member can be disengaged from one of the plurality of second grooves, which are spaced apart from each other by a predetermined angle (e.g., a range of 10 ° to 15 °), and then engaged in the other groove, so that the second mount can pivot within the predetermined angle range. For example, the second resilient member includes a second spring and a second ball, the second spring and the second ball configured to bias the second ball against one of the plurality of second grooves when the second mount is mounted to the stationary member.

The manner in which the third portion is pivoted relative to the stationary member has been described above, and it will be understood by those skilled in the art that the present invention is not limited to the above manner, and is within the scope of the present invention, so long as it is possible to achieve pivoting of the second camera relative to the stationary member within a predetermined range.

By having the second portion of the first mount "steeper" than the first portion and the fourth portion of the second mount "steeper" than the third portion, the minimum included angle (e.g., 30 degrees) formed when the first and second cameras pivot is less than the included angle (e.g., 85 degrees) formed when the mount is not so configured, thereby enabling a larger viewing angle scene.

In order to provide easy access to the first and second cameras for maintenance thereof, the overhanging portion of the support has a removable end cap 27 so that with the removable end cap removed, the first and second cameras can be accessed.

The above description is merely illustrative of the present invention, which is set forth to enable one of ordinary skill in the art to fully practice the present invention, and not to limit the present invention. The technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention, so as to achieve the purpose of the invention.
