The embodiment of the invention discloses a control method for a robot to enter an elevator, which is used for controlling the robot to execute an elevator riding task, can be executed by a sweeping robot and realizes walking among floors to carry out cleaning operation. As shown in fig. 1, the control method includes: step S101, controlling the mobile robot to move to a waiting position of the current floor according to a pre-scanned floor map, and then, entering step S102. It can be understood that when the mobile robot enters a new working scene, it needs to scan the map of the scene and then execute corresponding tasks according to the position of the mobile robot in the map for automatic working. When the mobile robot performs cleaning operation in the current floor, the relevant sensors can scan the floor environment to construct a map, identify the positions of various areas in the floor map, such as room positions, elevator positions, import and export positions and the like, store the scanned floor map in the mobile robot, and the mobile robot, the terminal device and/or the server can be connected through wired and/or wireless communication so as to guide the mobile robot to move. The wireless network communication connection includes, but is not limited to, wireless communication modes such as WiFi, Bluetooth (Bluetooth), Zigbee (Zigbee), narrowband Band Internet of Things (NB-Iot), and the like. Specifically, when the map is scanned, the contour of the elevator can be scanned completely, the scanned map is edited in the relevant application of the terminal device, and the contour of the elevator is drawn in the floor map, for example, a polygon is drawn to fit the contour of the elevator as much as possible to identify the position of the elevator door. In this manner, in step S101, the elevator position and the waiting position point of the corresponding floor can be specified from the previously scanned floor map. Then the mobile robot moves to the position right in front of the elevator door and a certain distance to the direction of the elevator door according to a set instruction, and the position is marked as an elevator waiting position point.
And S102, controlling the mobile robot to move from a waiting position to enter the elevator according to the change condition of the distance measurement data of the laser distance measurement sensor in the direction just opposite to the elevator door. In this embodiment, the inner wall of the elevator door or the elevator car reflects and blocks the laser emitted from the laser ranging sensor, and then the laser reflected from the elevator door is received by the same laser ranging sensor, so that the laser ranging sensor can be used to measure the ranging data of the laser ranging sensor in the direction opposite to the elevator door, and the ranging data can be used to calculate the distance between the elevator door and the mobile robot when the elevator does not reach and the elevator door is closed, and also can be used to calculate the distance between the inner wall of the elevator car and the mobile robot when the elevator reaches and the elevator door is opened, so that the ranging data of the laser ranging sensor in the direction opposite to the elevator door changes before and after the elevator door is opened, and thus, when the ranging data in the direction opposite to the elevator door changes in a certain range, the mobile robot is started to move into the elevator from the waiting, wherein, the variable distance measurement data accurately shows that the elevator door is changed from closed to open, or kept closed within a certain error floating interval. In this embodiment, this elevator waiting position point is closer to the elevator door, but it needs to ensure that the direction control accuracy of the mobile robot entering the elevator is reliable but the passenger is not blocked to wait for the elevator.
Compared with the prior art, the robot is controlled to execute the elevator taking task according to the change condition of the distance measurement data of the laser distance measurement sensor before and after the elevator door is opened and closed, the elevator waiting at the elevator waiting position and entering into the elevator from the elevator waiting position are included, so that the robot can accurately and flexibly enter and exit the elevator, and the experience of the robot and passengers taking the elevator is guaranteed. The unfinished work of the laser robot can be processed without going downstairs by a user, the operation is simple, the working efficiency is improved, and the labor cost is reduced.
As a specific example, as shown in fig. 2, a control method for a robot to enter an elevator includes:
step S201, controlling the mobile robot to move to a waiting position of the current floor according to the pre-scanned floor map, and then, entering step S202. The specific implementation of step S201 and step S101 are the same, and are not described herein again.
Step S202, at the moment that the mobile robot moves to the elevator waiting position point, judging whether the distance measurement data detected by the laser distance measurement sensor in the direction opposite to the elevator door is a second distance measurement distance, if so, entering step S205, otherwise, entering step S203. And the second distance measurement distance is distance measurement data of the elevator door obtained by measuring the opening time of the elevator door at the position of the elevator waiting position by the laser distance measurement sensor on the premise of no shielding of other obstacles.
Before the mobile robot moves to the elevator waiting position point, the laser emission direction of the laser ranging sensor needs to be adjusted to form a preset angle with the ground, so that a line segment corresponding to the horizontal distance from the elevator waiting position point to the front surface of the elevator door is positioned on the same vertical plane with laser emitted by the laser ranging sensor, wherein the laser emission direction of the laser ranging sensor of the mobile robot positioned at the elevator waiting position point is opposite to the elevator door. As shown in fig. 4, a position a is the elevator waiting position point, a line segment MN is AN elevator door, P is a laser ranging sensor on the mobile robot, a line segment PC is laser emitted by the laser ranging sensor, a laser emitting direction PC of the laser ranging sensor forms a preset angle b with a ground horizontal line QE, a line segment AN corresponding to a horizontal distance from the elevator waiting position point a to the front surface of the elevator door MN is on the same vertical plane as the laser PC emitted by the laser ranging sensor P, the laser emitting direction PC of the laser ranging sensor P of the mobile robot located at the elevator waiting position point a is opposite to the elevator door MN, the laser PC is emitted at a position C on the surface of the elevator door MN before the elevator door is not opened, the laser PC is emitted at a position D on the inner wall surface of the elevator after the elevator door is opened, and then the length of the line segment PD is the second ranging distance. According to the embodiment, the problem of accurately distinguishing the opening and closing of the elevator door is solved by adjusting the emitting direction of the laser on the vertical plane just opposite to the elevator door and measuring the distance. Preferably, b is greater than 30 degrees but less than 40 degrees, so that the phenomenon that a part of line segments CE forming the elevator calculated based on the line segments AN are infinitely long and do not accord with the actual size of the elevator is avoided; the horizontal distance from the elevator waiting position A to the front surface of the elevator door MN is 0.6 m, so that the elevator entering point is closer to the elevator door, the mobile robot can accurately master the position of the elevator door according to the appointed elevator entering point, and the mobile robot can safely and accurately enter the elevator along a straight line from the elevator entering point.
It should be noted that the obtaining of the distance measurement data by the mobile robot through the laser distance measurement sensor at the elevator waiting position point includes: the laser emission direction of the laser ranging sensor of the mobile robot positioned at the position of the elevator waiting position is adjusted to be just opposite to the elevator door, the distance can be measured by adopting the laser ranging principle after the laser emission direction of the laser ranging sensor positioned at the position of the elevator waiting position is adjusted, the laser ranging sensor emits laser forming a preset angle with the ground plane, the laser is received by the laser ranging sensor after being reflected by the elevator door or the wall surface inside the elevator car body, and the ranging distance E of the laser is as follows: e = c × t2/2, where c is the speed of light, t2 is the measurement duration of the laser beam with the distance E, the mobile robot may configure a timing clock, determine the time t2 by the timing clock, and further calculate the distance E of the laser.
Step S203, determining whether the product of the difference between the ranging distance detected by the laser ranging sensor later and the ranging data detected earlier and the cosine value of the preset angle is within a preset width range value, if so, entering step S205, otherwise, entering step S204, where the ranging data detected later is delayed from the ranging data detected earlier in time, and the ranging data detected earlier may be the ranging data detected at the moment when the robot just moved to the elevator waiting position or the ranging data detected at a certain moment after the robot just moved to the elevator waiting position. Said predetermined width range value is greater than the first predetermined width value and less than a second predetermined width value associated with the width dimension of the elevator, which may be equal to the width of the car of the elevator, i.e. the length of the line segment FN of fig. 4 that constitutes the elevator. And the first preset width value is smaller than the second preset width value by 0.2 meter, so that a preset width range value is formed, wherein the preset angle is an included angle formed by the laser emission direction of the laser ranging sensor and the ground, and when the mobile robot moves to the elevator waiting position point, a line segment corresponding to the horizontal distance from the elevator waiting position point to the front surface of the elevator door is positioned on the same vertical plane with the laser emitted by the laser ranging sensor.
And S205, controlling the mobile robot to enter the elevator from the elevator waiting position point along a horizontal projection line of a laser emission direction, wherein the laser emission direction of a laser ranging sensor of the mobile robot at the elevator waiting position point is just opposite to the elevator door. The mobile robot can accurately grasp the position of the elevator door according to the elevator entering direction appointed by the horizontal projection line along the laser emission direction, so that the mobile robot smoothly enters the elevator along a straight line from the elevator entering point.
Step S204, detecting whether the repeated judgment time of step S203 reaches the second preset time, if yes, entering step S206, otherwise, returning to step S203. In the embodiment, the distance measurement data of the laser distance measurement sensor is utilized to continuously judge the obstacle or passenger flow condition between the elevator waiting position point and the elevator door within the second preset time, because the distance measurement data of the laser distance measurement sensor can be changed due to the shielding effect of the obstacle under the condition that the elevator door is opened, the misjudgment is caused, and the time for triggering the robot is unstable. In some embodiments, the second predetermined time may be 1 minute. That is to say, when the mobile robot continuously judges that the product of the difference value between the ranging data detected by the laser ranging sensor later and the ranging data detected earlier and the cosine value of the preset angle does not fall within the preset width range value within 1 minute, it indicates that the interior of the elevator is full or the elevator accommodation amount is insufficient, and only the mobile robot can be controlled to stay at the elevator waiting position, and the mobile robot is determined to fail in the current elevator taking task. The embodiment monitors the elevator entering state of the mobile robot in a preset time through the change condition of the ranging data, realizes the control of the mobile robot on the elevator accurately and smoothly, and simultaneously avoids the influence on the normal operation of the elevator caused by the overlong elevator entering time of the robot. Of course, in other embodiments, the second predetermined time may be flexibly configured according to actual needs, and is not specifically limited herein.
And step S206, the mobile robot is not controlled to enter the elevator.
The embodiment described in the foregoing steps S201 to S206 first determines whether the robot directly and stably enters the elevator, and then under the condition that the robot cannot directly and stably enter the elevator, converts the difference value of the ranging data of the laser ranging sensor at the elevator waiting position point into the horizontal distance variation value from the elevator waiting position point to the elevator door and the inner wall of the elevator car, and then sets the predetermined width range value to accurately control the robot to enter the elevator, thereby overcoming the influence of environmental factors on the ranging parameters, and further avoiding that the robot cannot reach the elevator due to being blocked by passengers or other objects near the elevator waiting position point.
As another specific embodiment, in the step S202, at the time when the mobile robot moves to the elevator waiting position, it is detected that the distance measurement data of the laser distance measurement sensor in the direction facing the elevator door is a first distance measurement distance, where the first distance measurement distance is the distance measurement data of the laser distance measurement sensor when the elevator door is closed, which is measured at the elevator waiting position by the laser distance measurement sensor on the premise that no other obstacle is blocked.
Then, judging whether the product of the difference value between the ranging distance detected by the laser ranging sensor after the laser ranging sensor and the first ranging distance and the cosine value of the preset angle is within the preset width range value, if so, entering the step S205, otherwise, entering the step S204, wherein the ranging data detected by the laser ranging sensor after the laser ranging sensor is: after the laser ranging sensor detects and acquires the first ranging distance, ranging data detected in the direction opposite to the elevator door has a delay relation in detection time relative to the first ranging distance detected in advance; the preset width range value is greater than a first preset width value and less than a second preset width value, the first preset width value is less than the second preset width value, the second preset width value is associated with the width dimension of the elevator, the second preset width value can be equal to the width of the elevator compartment, namely the length of a line segment FN of the elevator composed by the graph 4, and the first preset width value is less than the second preset width value by 0.2 meter, so that the preset width range value is formed, wherein the preset angle is an included angle formed by the laser emission direction of the laser ranging sensor and the ground, so that when the mobile robot moves to the elevator waiting position point, a line segment corresponding to the horizontal distance from the elevator waiting position point to the front surface of the elevator door is on the same vertical plane as the laser emitted by the laser ranging sensor. When the elevator door is not opened, the difference value between the ranging distance detected by the laser ranging sensor and the first ranging distance is 0, and obviously is not within a preset width range value, wherein the ranging data (equivalent to the ranging distance) detected by the laser ranging sensor is the length of a line segment PC and is also equivalent to the first ranging distance; when the elevator door is opened, as shown in fig. 4, the distance measurement data detected by the laser distance measurement sensor is the length of the line segment PD, which is recorded as the second distance measurement distance, and the distance measurement data is changed from the first distance measurement distance to the second distance measurement distance, the difference between the second distance measurement distance and the first distance measurement distance is the length of the line segment DC, and then the product of the difference between the second distance measurement distance and the first distance measurement distance and the cosine value of the preset angle b is the line segment QE, which is equal to the length of the line segment FN and is equal to the car width of the elevator, but because the passenger blocks the influence of the environmental factors such as interference, obstacle contour interference, etc., the product of the difference between the distance measurement distance detected by the laser distance measurement sensor and the first distance measurement distance after the elevator door is opened and the cosine value of the preset angle is not fixed, so that the aforesaid product is determined to be within the, the robot can be triggered to enter the elevator. In this embodiment, in order to avoid the influence of environmental factors such as contour interference of passengers and obstacles on distance measurement data, which may cause inaccuracy of the distance measurement result of the robot, in practical application, optionally, a position parameter floating interval corresponding to a product of a difference between the distance measurement distance detected by the laser distance measurement sensor and the first distance measurement distance and a cosine value of the preset angle, that is, a compartment size parameter floating interval of the elevator, may be determined based on a certain strategy, so that when the cosine value of the distance measurement data change value of the robot at the elevator waiting position point is located in the floating interval, it may be considered that it indicates that the elevator door is open and the barrier effect of the obstacle on the route from the elevator waiting position point to the outside of the elevator is limited, and the robot may be accurately triggered to enter the elevator from the elevator waiting position point. According to the step, the elevator waiting position point is detected, so that the safety accident caused by the fact that the robot enters the elevator under the condition that the robot is blocked by passengers or other objects nearby the elevator waiting position point and cannot reach the elevator waiting position point is avoided, and the accuracy of judging the opening of the elevator by the robot is improved.
