Accordingly, only the robot may operate in the robot working area without the participation of the worker. When some abnormal factors occur and need to be handled by workers in person, the workers can enter the working area of the robot to participate in the handling.

Taking a picking system in a warehouse logistics environment as an example, please refer to the system structure diagram of the cargo picking system shown in fig. 1, the cargo picking system 100 includes: the robot 10, the dispatching server 20, the shelf area 30 and the sorting station 40, the shelf area 30 is provided with a plurality of shelves 31, various goods are placed on the shelves 31, for example, as the shelves where various goods are placed are seen in supermarkets, and the shelves 31 are arranged in a shelf array form.

The whole robot working area can be covered by a Wireless Fidelity (WIFI) network, the dispatching server 20 and the robot 10 perform Wireless communication through the WIFI network, a worker enables the dispatching server 20 to work through the operation console 60, and the robot 10 executes a cargo carrying task under the control of the dispatching server 20. For example, the scheduling server 20 plans a movement path for the robot 10 in accordance with the transfer task, and the robot 10 travels along an empty space (a part of a passage through which the robot 10 passes) in the rack array in accordance with the movement path. In order to plan a moving path for the robot 10, a working area of the robot 10 (the working area includes at least the rack area 30 and the picking station 40) is divided into a plurality of sub-areas (i.e., cells), and the robot 10 moves from sub-area to form a moving track.

Referring to fig. 2, the robot 10 may include a driving mechanism 101 by which the robot 10 can move within the work space, and the robot 10 may further include a lifting mechanism 102 for carrying the racks, and the robot 10 may move below the target rack 31, lift the target rack 31 using the lifting mechanism 102, and carry to the assigned picking station 40. The entire target shelf 31 is lifted from the ground when the lifting mechanism 102 is lifted up, so that the robot 10 carries the target shelf 31, and the target shelf 31 is placed on the ground when the lifting mechanism 102 is lowered. The target recognition unit 103 on the robot 10 can effectively recognize the target shelf 31 when the robot 10 lifts the target shelf 31.

Therefore, how to control the robot to avoid the working personnel in all directions in real time is necessary to improve the safety of the working personnel in the working area of the robot.

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.

Example one

Fig. 3 is a flowchart of a human-machine cooperation control method according to an embodiment of the present invention, which is applicable to a situation where a robot is controlled to avoid a worker to travel so as to ensure safety of the worker. The method specifically comprises the following steps:

step 310, at least one of the scheduling server and the device to be positioned determines the location information of the device to be positioned according to the wireless communication signal strength between the device to be positioned and the auxiliary device and the location information of the auxiliary device.

In the specific embodiment of the invention, the equipment to be positioned is equipment which is configured on a worker, can move along with the movement of the worker and is used for positioning the worker. For example, the device to be positioned may be mounted on a helmet of a worker, or may be carried around by the worker, etc. The auxiliary device refers to a device configured in a work area for providing positioning assistance information. The position information of the auxiliary device is thus predetermined, in which the position information of the auxiliary device can be stored beforehand.

In this embodiment, the device to be positioned and the auxiliary device are both wireless communication devices, and the device to be positioned and the auxiliary device may be the same device, for example, both the device to be positioned and the auxiliary device may be low power consumption bluetooth devices, or may be different devices. One of the device to be positioned and the auxiliary device may be a signal transmitting device, and correspondingly, the other may be a signal receiving device. Wherein, in order to improve the accuracy to staff's location, auxiliary assembly can be a plurality ofly, can also set up in the working area with certain rule, for example fix the setting above the working area with latticed, be convenient for to the accurate and omnidirectional location of positioning equipment.

In this embodiment, wireless communication can be performed between the device to be positioned and the auxiliary device, so that the device to be positioned is positioned based on the position information of the auxiliary device through real-time interaction between the device to be positioned and the auxiliary device. The position information of the auxiliary equipment, the determined position information of the equipment to be positioned and the position information of the robot are all based on position coordinates in the same map coordinate system. For example, a two-dimensional coordinate system is created from a map of the robot work area projected onto the ground for locating the robot and the staff located in the work area.

In this embodiment, one of the devices to be positioned and the auxiliary device may be a wireless signal transmitting device, and correspondingly, the other device may be a wireless signal receiving device. One side of the wireless signal transmitting device can perform wireless signal broadcasting in real time, and one side of the wireless signal receiving device can perform wireless signal scanning in real time. Therefore, according to the scanning result of the wireless signals, the position information of the auxiliary equipment which is successfully communicated is used as one of the positioning bases of the equipment to be positioned.

Under the condition that normal operation of the equipment is ensured, along with the change of the distance between the equipment, the strength of the signals received between the equipment is changed. The wireless communication Signal Strength may be an RSSI (Received Signal Strength Indication) value. Therefore, according to the scanning result of the signals, the signal strength of the wireless signal transmitting equipment which is successfully communicated is used as one of the positioning bases of the equipment to be positioned.

Specifically, because the position information of the auxiliary device is known, when a worker enters a robot working area and the working area is within a wireless communication range of the auxiliary device, the device to be positioned carried by the worker can perform real-time signal interaction with the auxiliary device in the working area to obtain the position information of the auxiliary device with successful signal interaction and the scanned wireless communication signal strength, at least one of the server and the device to be positioned is scheduled according to different configuration modes of the devices in the working area, and the position information of the device to be positioned is calculated according to the position information of the auxiliary device and the wireless communication signal strength. The position information of the equipment to be positioned can be calculated by the equipment to be positioned and transmitted to the scheduling server, or the receiving end of the signal can send the position information of the auxiliary equipment and the strength of the wireless communication signal to the scheduling server, and the scheduling server calculates and obtains the position information of the auxiliary equipment and the strength information of the wireless communication signal according to the received position signal of the auxiliary equipment.

In addition, before calculating the location information of the device to be positioned, if the location information of a plurality of auxiliary devices exists, the plurality of auxiliary devices may be screened according to the wireless communication signal strength, so as to obtain the location signal of the auxiliary device with the strongest signal strength for positioning.

For example, if the device to be positioned is a wireless signal receiving device and the auxiliary device is a wireless signal transmitting device fixedly arranged in a working area, the auxiliary device may broadcast its own position information and ID information in real time or periodically, and the device to be positioned may scan wireless signals in real time or periodically. The ID may represent a device number or a preset unique identifier of the auxiliary device, and the auxiliary device to which the location information belongs may be distinguished at a later stage. The device to be positioned can calculate the position information of the device to be positioned according to the scanned position information of the auxiliary device and the strength of the wireless communication signal, and upload the position information of the device to be positioned to the scheduling server; or the device to be positioned can upload the scanned position information of the auxiliary device and the wireless communication signal strength to the scheduling server, and the scheduling server calculates the position information of the device to be positioned. In order to reduce the uploading amount of data, the belt positioning device can be adopted to calculate the position information.

For another example, if the device to be positioned is a wireless signal transmitting device and the auxiliary device is a wireless signal receiving device fixedly disposed in the working area, the device to be positioned may transmit wireless signals in real time or periodically, and the auxiliary device may scan wireless signals in real time or periodically. The auxiliary equipment which scans the wireless signal of the equipment to be positioned can upload the position information, ID, wireless communication signal strength and other information of the auxiliary equipment to the scheduling server, and the scheduling server calculates the position information of the equipment to be positioned.

In this embodiment, when the device to be positioned calculates the position information, and when only one piece of position information is calculated, the position information may be directly used as the position information of the device to be positioned. Alternatively, the distance between the device to be positioned and the auxiliary device may be calculated based on the wireless communication signal strength, and the position range of the device to be positioned may be determined according to the one position information and the distance between the device to be positioned and the auxiliary device. When the position information to be calculated is multiple, the calculation of the arithmetic mean value can be performed according to the multiple position information and the signal intensity related to the multiple position information to obtain the position information of the device to be positioned. A number threshold may be set, and if the number of the location information according to the calculation exceeds the number threshold, the location information is screened according to the signal strength.

For example, assuming that the number threshold is 3, three signal strength values with signal strengths ranked in the top three and their associated location information are selected for calculation, and the 3 location information according to which the calculation is based are (X1, Y1), (X2, Y2) and (X3, Y3), and the 3 location information has associated signal strengths RSSI1, RSSI2 and RSSI3, respectively. The position information (X, Y) of the device to be positioned can be calculated according to the following formula: x ═ X (X1 × RSSI1+ X2 × RSSI2+ X3 × RSSI3)/(RSSI1+ RSSI2+ RSSI3), Y ═ Y (Y1 × RSSI1+ Y2 × RSSI2+ Y3 × RSSI3)/(RSSI1+ RSSI2+ RSSI 3). Therefore, the coarse positioning of the device to be positioned can be realized through the interaction between the device to be positioned and the auxiliary device, the positioning accuracy is about 1 meter, and the safety control requirement is met.

And step 320, controlling the robot in the working area to avoid the working personnel carrying the equipment to be positioned to run by the scheduling server according to the position information of the equipment to be positioned.

In the embodiment of the invention, the robot can be controlled in real time according to the position information of the equipment to be positioned by the scheduling server in the robot working system. Specifically, through interaction between the device to be positioned and the auxiliary device, the position information of the device to be positioned may be calculated by the device to be positioned and transmitted to the scheduling server, or may be calculated by the scheduling server according to the received position signal of the auxiliary device and the received strength information of the wireless communication signal, and the scheduling server may finally receive or calculate the position information of the device to be positioned. Meanwhile, the dispatching server can acquire real-time position information of each robot in a working area in real time, so that the dispatching server can determine the relative position between a worker carrying the equipment to be positioned and each robot according to the position information of the equipment to be positioned and the real-time position information of each robot, and plan a real-time avoidance path of the robot according to the relative position. Meanwhile, the dispatching server can acquire real-time speed information of each robot in a working area in real time, so that the dispatching server can control the speed of the robot, such as speed reduction, stop or control within a certain safety range, according to the real-time speed information of each robot and the relative position of the worker and the robot, and can control the robot to recover to a normal working state when the robot is determined to be far away from the worker according to the real-time relative position information. It will be appreciated that the closer the distance between the robot and the worker, the lower the speed at which the robot is controlled to travel.

The safety range of the worker can be predetermined by taking the worker as a center, for example, the range with the radius of 2 meters by taking the worker as the center. Therefore, according to the relative positions of the staff and the robot, when the robot is detected to enter or be about to enter the safety range of the staff, the avoidance path and the speed can be re-planned.

In this embodiment, based on the position of the worker, the position of the robot, and the speed of the robot, the path and the speed of the robot can be re-planned, so that the scheduling server issues a control instruction to the corresponding robot according to the re-planned control information, so that the robot adjusts the motion state in time, and the safety of the worker is guaranteed.

For example, fig. 4 is a schematic diagram of a human-machine cooperative control system. As shown in fig. 4, the human-machine cooperation control system 400 may include at least a scheduling server 410, an auxiliary device 420, and a device to be positioned 430. A worker 441 carrying the device 430 to be positioned and at least one robot 442 may be included in the robot work area 440; at a certain height above the working area 440, e.g. 3 meters, the auxiliary devices 420 are arranged in a grid-like fixed arrangement, e.g. one auxiliary device is installed in one area every 5 x 5 meters. The entire work area is covered by a wireless network 450, such as a WIFI network, and accordingly, all of the robots 442, auxiliary devices 420, and devices 430 to be located may be connected to the dispatch server 410 via the wireless network 450. The auxiliary device 420 stores position information, an ID and the like, and the position information of the auxiliary device 420 is acquired and the wireless communication signal strength is detected through interaction between the device 430 to be positioned and the auxiliary device 420, so that the device 430 to be positioned or the scheduling server 410 can position the worker 441 carrying the device 430 to be positioned through calculation of the position information, and the scheduling server 410 can timely control the robot 442 to avoid the worker 441 to run according to the position information of the worker 441 and the position information and the speed information of the robot 442, and the safety of the worker 441 is guaranteed.

According to the technical scheme, auxiliary positioning equipment with known positions can be configured in the robot working area, a worker can configure equipment to be positioned, when the worker enters the robot working area, the equipment to be positioned and the auxiliary equipment are in wireless communication, the equipment to be positioned is positioned based on the position information of the auxiliary equipment, and therefore the robot in the working area is controlled to avoid the worker to drive according to the position information of the equipment to be positioned. The embodiment of the invention is based on the real-time interaction between the equipment to be positioned and the auxiliary equipment, realizes the omnibearing avoidance of the robot to surrounding workers by positioning the workers carrying the equipment to be positioned in real time and controlling the running state of the robot in real time, and improves the safety guarantee of the workers entering the working area of the robot.

Example two

The present embodiment provides a preferred implementation of the human-machine cooperation control method based on the first embodiment, and can control the robot to avoid the path and the speed. Fig. 5 is a flowchart of a human-machine cooperation control method according to a second embodiment of the present invention, wherein step 320 may further specifically include step 520 and step 540, as shown in fig. 5, the method specifically includes the following steps:

step 510, at least one of the scheduling server and the device to be positioned determines the location information of the device to be positioned according to the wireless communication signal strength between the device to be positioned and the auxiliary device and the location information of the auxiliary device.

Optionally, before determining the location information of the device to be positioned according to the strength of the wireless communication signal between the device to be positioned and the auxiliary device and the location information of the auxiliary device, the method further includes: and screening out target auxiliary equipment for positioning the equipment to be positioned according to the strength of the wireless communication signal between the equipment to be positioned and the auxiliary equipment.

In the embodiment of the invention, under the condition of ensuring the normal operation of the equipment, the strength of the received signals between the equipment is changed along with the change of the distance between the equipment. Therefore, when there is location information of multiple auxiliary devices, the multiple auxiliary devices can be screened according to the wireless communication signal strength, so as to reserve the location signal of the target auxiliary device with the strongest signal strength for positioning. A number threshold may be set, and if the number of the location information according to the calculation exceeds the number threshold, the location information is screened according to the signal strength. Therefore, the real-time position of the equipment to be positioned is calculated according to the screened position information of the target auxiliary equipment.

And step 520, the scheduling server determines an avoidance path of the robot in the working area according to the collected position information of the robot in the working area and the position information of the equipment to be positioned.

In the embodiment of the invention, the robot in the working area originally drives according to the path planned by the scheduling server according to the operation instructions of transportation and the like issued by the scheduling server. Meanwhile, the scheduling server can acquire real-time position information of each robot in the working area in real time. When the working personnel enter the working area of the robot, the running path of the robot needs to be changed in time according to the real-time position information of the robot and the working personnel, and the avoiding path of the running of the working personnel is avoided on the premise of ensuring the normal carrying and other operations of the robot. The present embodiment does not limit the manner of planning the avoidance path, and any manner capable of planning the avoidance path may be applied to the present embodiment. For example, the safety range of the worker is preset by taking the worker as a center, so that the avoidance path of the robot is generated based on the minimum path bypassing the safety range of the worker on the basis of the originally planned path of the robot. Therefore, the effect of avoiding the working personnel to ensure the safety of the working personnel and not influencing the normal work of the robot is achieved.

And step 530, the scheduling server determines the adjustment speed of the robot in the working area according to the acquired speed information of the robot in the working area and the relative position between the robot in the working area and the staff carrying the equipment to be positioned.

In the embodiment of the invention, the robot in the working area originally runs at the speed set by the dispatching server according to the operation instructions of transportation and the like given by the dispatching server. Meanwhile, the scheduling server can acquire real-time speed information of each robot in the working area in real time. When the working personnel enter the working area of the robot, the dispatching server can also control the running speed of the robot in time according to the real-time position information of the robot and the working personnel, and determine the adjusting speed of the robot in the working area. The present embodiment does not limit the control manner of the adjustment speed, and any manner capable of determining the adjustment speed may be applied to the present embodiment.
