Fig. 2 shows a flowchart of a method for setting up a WiFi hotspot by a multi-working robot networking according to an embodiment of the present invention, which specifically includes the following steps:
s201, a user generates a networking instruction based on an APP client on a first user terminal;
s202, the first user terminal sends a networking instruction to the first industrial robot by adopting a BLE technology;
s203, after the first industrial robot identifies the networking command, starting a first WiFi module on the first industrial robot to establish a WiFi hotspot;
and S204, after the first industrial robot establishes the WiFi hotspot, feeding back a WiFi hotspot success message to the first user terminal based on a BLE technology.
The system architecture based on networking of the multiplex robots firstly needs to complete a networking process based on the multiplex robots, so that coverage of WiFi hot spots is achieved, data receiving and sending among the multiplex robots are achieved, and the like.
Because the first industrial robot can set a specific WiFi hotspot, in the specific implementation process, the name or password of the WiFi hotspot can be changed according to the scene needs, the name or password modification is basically completed by the user operating on the first user terminal based on the APP client, then the first user terminal sends a hotspot rename instruction to the first industrial robot based on the BLE technology, the first industrial robot receives the hotspot rename instruction initiated by the first user terminal, the hotspot rename instruction is generated by the user of the first user terminal based on the APP client interface, and the hotspot rename instruction comprises modifying a network name and/or modifying a network password; after the first industrial robot identifies the hotspot correction instruction, starting a WiFi module on the first game terminal to rename the WiFi hotspot; and after the successful renaming of the WiFi hotspots, broadcasting WiFi signals outwards based on the first WiFi hotspot after renaming.
In a specific implementation process, the first industrial robot may further receive a hotspot closing instruction initiated by the first user terminal, where the hotspot closing instruction is generated by a user of the first user terminal based on the APP client interface; after the first industrial robot identifies the hotspot closing instruction, a WiFi module on the first game terminal is started to close the WiFi hotspot.
Fig. 3 shows a flowchart of a method for adding a WiFi hotspot by a multi-working robot networking according to an embodiment of the present invention, which specifically includes the following steps:
s301, the user generates a WiFi hotspot adding instruction based on an APP client on a second user terminal;

s303, starting a WiFi module on the second industrial robot by the second industrial robot based on a WiFi adding instruction to search WiFi hotspots;
and S304, the WiFi module on the second industrial robot searches the corresponding WiFi hotspot based on the network name and joins based on the network password.
In a specific implementation process, in the process of searching for the WiFi hotspot, a WiFi module of a second industrial robot judges whether a first network name is the same as a second network name, and if the first network name is the same as the second network name, the first WiFi hotspot initiated by the first industrial robot is judged to be a WiFi hotspot needing to be added; and after the first WiFi hotspot initiated by the first industrial robot is judged to be the WiFi hotspot needing to be added, adding the first WiFi hotspot based on the second network password.
In a specific implementation process, if the second network password is the same as the first network password, the WiFi module of the second industrial robot acquires a WiFi hotspot joining success message and feeds the joining success message back to the APP where the second user terminal is located on the basis of the BLE technology; if the second network password is different from the first network password, the WiFi module on the second industrial robot acquires a WiFi hotspot joining failure message, and feeds the joining failure message back to the APP where the second user terminal is located on the basis of the BLE technology.
Based on the system shown in fig. 1, when there are multiple industrial robot devices to be networked (such as multiple industrial robots to participate in a cooperative mode or a shared mode), an initiator (assumed to be a user on a first user terminal) first performs "network creation" through an APP on the user terminal, and the network creation usually needs to specify a "name" and a "password" of the network. For authentication when other industrial robots join the network. The command of the "network creation" and the "name" and "password" of the network are transmitted to the industrial robot corresponding to the initiator by means of BLE. And after receiving the instruction, the WiFi module on the industrial robot starts a WiFi hotspot consistent with the name by using the received name. And the password of the WiFi hotspot is the received password value. After the creation is successful, the WiFi module can feed back the APP of the creator through BLE. After the APP receives the prompt of successful creation of the AP hotspot, the creator can tell the name and the password of the network created by other users, so that other users can conveniently join the AP hotspot. When the user on the other user terminal wants to join the network, the user directly inputs the network 'name' and 'password' notified by the creator through the APP interface, and clicks the 'join' button. The command can be transmitted to the corresponding industrial robot through BLE, the WiFi module of the industrial robot can start WiFi hotspot scanning after receiving the command, received network name and password are used for retrieving WiFi hotspots existing around, and if WiFi hotspots with the same names exist, the command is tried to be added through the password. And after the network is successfully added, feeding back to the corresponding APP through BLE to indicate that the network is successfully added.
After a plurality of industrial robots form networking communication based on WiFi hotspots, the communication process between user terminal equipment and the communication process between the industrial robot equipment and the industrial robot equipment can be established, so that the sharing of user information and industrial robot information under the same networking mode can be realized, the running data of each industrial robot collected by each industrial robot based on a processor can be broadcasted in time, the user reference on each user terminal in a group can be provided, the operation of users is facilitated, and a corresponding decision basis is provided for a follow-up cooperative operation mode.
Therefore, near field communication is achieved between the industrial robot and the user terminal based on the BLE technology, the WiFi module on the industrial robot is controlled based on the user terminal, and the WiFi hotspot is started, so that networking processes of multiple robots in a certain area are achieved, the possibility of interconnection and intercommunication among all industrial robots under WiFi coverage is achieved, and follow-up networking based on the WiFi technology, adding of new equipment and information interaction among all industrial robots based on the WiFi technology are guaranteed.
BLE, Bluetooth Low Technology is a Low power consumption Bluetooth Technology developed from conventional Bluetooth, and is a relatively common near field communication method due to its fast connection speed, Low power consumption for transmission/reception, small data transmission amount, and moderate communication distance, and is widely used in smart phones.
BLE devices can be generally divided into a central device (Center) and a Peripheral device (Peripheral), wherein the former plays a role as a host in the connection process of the devices, and generally the role is a user terminal device such as a mobile terminal; the latter plays the role of a slave during the connection of the device, typically a BLE device with certain special functions, such as a BLE bracelet, a BLE sensor, etc.
The data communication mode of BLE is divided into two types, namely connection-based communication and non-connection-based communication, wherein the former scenario is that after connection is established between BLE master equipment and BLE slave equipment, the communication between the BLE master equipment and the BLE slave equipment is connection-based communication; the latter occurs in a scenario where BLE sends broadcast information out from the device actively, and the broadcast information usually carries some extra information of the device, such as the name of the device or some data structure customized by the developer.
Adopt BLE's mode to carry out communication connection between user terminal and the industrial robot, when user terminal launches group communication or the collaborative work between the multi-device, transmit industrial robot for through BLE's mode, industrial robot sends away the instruction that user terminal sent based on WIFI technique broadcast or point-to-point. BLE is as a short distance (within 20 m), low-speed, low-power consumption's communication mode, accords with wireless control requirement very much, therefore, joins BLE device at industrial robot end for communicate with user's user terminal, make the user realize through BLE equipment that control actual equipment carries out the interactive action between industrial robot equipment, for example the operating mode information of each industrial robot, the update information that each equipment joined. When a first user and a second user are present, the first user controls the first industrial robot through the first user terminal, and the second user controls the second industrial robot through the second user terminal. The user terminal and the industrial robot are communicated in a BLE mode (the user terminal serves as a BLE master device, and the device end serves as a BLE slave device). When a first user wants to know the state of each industrial robot device, the user sends state acquisition information through man-machine interaction of an APP interface of a first user terminal, and the instruction is transmitted to the first industrial robot through BLE in a wireless mode. After receiving the instruction from the BLE, the first industrial robot encodes the instruction into WIFI information and sends the WIFI information. If the WIFI module of the second industrial robot receives the WiFI information sent by the first industrial robot, the second industrial robot extracts effective data from the WiFi information and sends the effective data to the second user terminal through BLE, and after the second user terminal receives the effective data, the effective data can be displayed, reminded or specially-effective on APP. Such a procedure enables a first industrial robot of a first user to visually see data information on a first industrial robot after sending the information to a second industrial robot of a second user.
Near field communication is realized between industrial robot and user terminal based on BLE technique, then generates corresponding wiFi information broadcast or one-way transmission out based on user terminal to realized the data sharing between each industrial robot and the possibility of information propagation under the networking mode, richened the variety that industrial robot controlled. After being analyzed by the user terminal, effective information in the WiFi information can be timely broadcasted to the user terminal where each industrial robot is located, so that each user under networking can know the running state, parameter performance and user behavior of the industrial robot related to the condition of each user, and corresponding decision and basis can be provided for the user terminal. Correspondingly, in the embodiment of the present invention, a User Datagram Protocol (UDP) packet with a special instruction is constructed based on a WiFi technology, when a User (for example, a first User) wants a multidirectional cooperative work instruction, the User sends the multidirectional cooperative work instruction to the communicated industrial robot through BLE of a User terminal, and after receiving the instruction, the industrial robot broadcasts a UDP broadcast packet through the WiFi technology and sends the UDP broadcast packet to all WiFi-connected industrial robots. When one of the industrial robots (such as the second industrial robot to the Nth industrial robot) receives the broadcast packet, that is, the broadcast packet indicates that the industrial robot is subjected to the multi-directional cooperative work instruction, and completes the corresponding controlled process based on the cooperative work instruction,
fig. 4 shows a flowchart of a method for collaborative work under a networking of a plurality of industrial robots in an embodiment of the present invention, which specifically includes the following steps:
s401, a user generates a user operation instruction based on an APP client on a first user terminal;
s402, the first user terminal sends a user operation instruction to the first industrial robot by adopting a BLE technology;
s403, the first industrial robot analyzes the user operation instruction, analyzes the instruction type of the user operation instruction, and generates a corresponding WiFi data packet based on the instruction type;
in a specific implementation process, when the user operation instruction is analyzed to be a one-way cooperative operation instruction, acquiring an IP address corresponding to the one-way cooperative operation instruction based on the equipment information list, and sending the one-way cooperative operation instruction to a corresponding second industrial robot by adopting a set port and the IP address; when the analyzed user operation instruction is a multi-direction cooperative operation instruction, the multi-direction cooperative operation instruction is generated into a UDP broadcast packet which can be broadcast by a WIFI technology, and the UDP broadcast packet is sent to a plurality of industrial robots needing cooperative operation based on the WiFi modules corresponding to the first industrial robots.
In a specific implementation process, the user operation instruction is packaged with: industrial robot ID and collaborative work orders. The cooperative operation instruction can be realized by user operation behaviors, such as a plurality of robot controlled user operation instructions to complete group magic dancing, or trigger a time sequence pipeline operation process, or perform group controllable test behaviors, and the like.
In a specific implementation process, after the first industrial robot receives a UDP unicast or broadcast equipment information list sent by a WiFi hotspot, the first industrial robot caches the equipment information list; or after the first industrial robot receives the equipment information list sent by the WiFi hotspot next time in a UDP unicast or broadcast mode, the first industrial robot refreshes the equipment information list. The device information list includes: connecting to all industrial robot IDs under the WiFi hotspot and connecting to the industrial robot IP addresses under the WiFi hotspot.
