Background
In recent years, artificial intelligence has been rapidly developed, and a distribution service robot has been developed. At present, in hotels in some cities, it is not easy to see that running delivery service robots are used for delivering objects for guests instead of people, which is a typical application scene of the delivery service robots. When the distribution service robot operates in the typical indoor application scenario, one of the necessary requirements is to go upstairs and downstairs by the elevator car. When the distribution service robot is outside the elevator and needs to take the elevator, the distribution service robot needs to call the elevator outside the elevator like a person, and the person calls the elevator by pressing a call key of the current floor. Accordingly, the robot is used to "tell" the elevator controller about its own elevator riding request by wireless communication technology, so that the elevator can make corresponding actions. Because the dispatch service robot calls the elevator outside the elevator, actually, the dispatch service robot requests the elevator controller, the elevator controller is positioned at the top of the elevator car, and the current floor of the car is possibly far away from the floor of the robot, a wireless communication technology for calling the elevator outside must select a technology supporting a long distance, such as 4G, loRa, which is also a technology commonly used in the industry. However, in the industry, 4G or LoRa is generally used singly, and due to the limitation of the technology, when 4G or LoRa is used singly, each technology inevitably has some short boards, which directly reflects that stable and effective communication cannot be maintained all the time, for example, in some specific scenes, 4G signals are unstable or no 4G signals exist at all, and packet loss exists in LoRa communication.

In the existing elevator control method, when the distribution service robot calls an elevator outside an elevator car, a single wireless communication technology (such as 4G, loRa) is used, but the stable and effective communication quality cannot be always maintained due to the limitation of each wireless communication technology, so that the distribution service robot is overtime in distribution tasks and even fails in distribution tasks.
Based on the above, in the elevator control method of the present invention, when the distribution service robot is outside the elevator car, the distribution service robot can communicate with the elevator controller through the 4G communication link and the LoRa communication link, thereby making up the technical problem that the stable and effective communication quality cannot be always maintained due to the limitation of each wireless communication technology under the condition of only 4G means or only LoRa means.

And step S104, when the distribution service robot is in the elevator car, establishing Bluetooth connection with the elevator controller to realize the communication between the distribution service robot and the elevator controller in a Bluetooth communication link mode.
Bluetooth is an open global specification for wireless data and voice communications, and is a special short-range wireless technology connection that establishes a communication environment for fixed and mobile devices based on a low-cost short-range wireless connection.
Specifically, the bluetooth communication may be a communication that runs to which floor, and the bluetooth communication is not particularly limited in the embodiment of the present invention.
In an embodiment of the present invention, there is provided a method of elevator control for a delivery service robot, the method including: when the distribution service robot is outside the elevator cage, the distribution service robot communicates with the elevator controller through a 4G communication link and a LoRa communication link to call the distribution service robot into the elevator cage; when the distribution service robot is in the elevator car, a bluetooth connection is established with the elevator controller to enable communication of the distribution service robot with the elevator controller by means of a bluetooth communication link. It can be known from the above description that in the elevator control method of the present invention, when the distribution service robot is outside the elevator car, the distribution service robot can communicate with the elevator controller through the 4G communication link and the LoRa communication link, thereby making up for the technical problem that the stable and effective communication quality cannot be maintained all the time due to the limitation of each wireless communication technology in the 4G approach only or the LoRa approach only.
The foregoing has outlined the method of elevator control of the present invention and the details thereof are set forth in the detailed description that follows.
In an alternative embodiment of the present invention, referring to fig. 2, the step S102, which communicates with the elevator controller through the 4G communication link and the LoRa communication link, specifically includes the following steps:
step S201, elevator call requests are sent to an elevator controller through a 4G communication link and a LoRa communication link respectively, so that after the elevator controller receives the elevator call requests, elevator call responses are sent to a distribution service robot through the 4G communication link and the LoRa communication link respectively, and an elevator is controlled to execute corresponding actions according to the elevator call requests, wherein the elevator call requests carry unique call numbers, and the elevator call responses carry the same call numbers as the corresponding elevator call requests;
specifically, when the service logic of the delivery service robot judges that the service logic of the delivery service robot needs to call an elevator, an elevator call request is generated, and the elevator call request is constructed into two specific data packets, one for transmission on the 4G communication link and one for transmission on the LoRa communication link, wherein the two data packets have the same call number. And simultaneously initiating the transmission of the two data packets on the 4G communication link and the LoRa communication link, and further realizing the transmission of the elevator call request to the elevator controller through the 4G communication link and the LoRa communication link respectively.
After receiving the elevator call request, the elevator controller sends an elevator call response to the distribution service robot through a 4G communication link and a LoRa communication link respectively, and controls the elevator to execute corresponding actions according to the elevator call request, specifically:
(1) If the elevator controller receives the elevator call request of the 4G communication link, the elevator call request of the 4G communication link is processed, the elevator call request of the LoRa communication link, which is the same as the call number of the elevator call request of the 4G communication link, is discarded, an elevator call response (the elevator call response corresponding to the elevator call request) is sent to the distribution service robot through the 4G communication link and the LoRa communication link, and the elevator is controlled to execute corresponding actions (such as moving to a specified floor) according to the processing result of the elevator call request;
(2) If the elevator controller receives the elevator call request of the LoRa communication link, the elevator call request of the LoRa communication link is processed, the elevator call request of the 4G communication link, which is the same as the call number of the elevator call request of the LoRa communication link, is discarded, an elevator call response (the elevator call response corresponding to the elevator call request) is sent to the distribution service robot through the 4G communication link and the LoRa communication link respectively, and the elevator is controlled to execute corresponding action (such as moving to a specified floor) according to the processing result of the elevator call request;
(3) If the elevator controller receives the elevator call request of the 4G communication link and the elevator call request of the LoRa communication link at the same time, the elevator call request of the 4G communication link is processed, the elevator call request of the LoRa communication link, which has the same call number as the elevator call request of the 4G communication link, is discarded, an elevator call response (the elevator call response corresponding to the elevator call request) is sent to the distribution service robot through the 4G communication link and the LoRa communication link respectively, and the elevator is controlled to execute corresponding action (such as moving to a specified floor) according to the processing result of the elevator call request.
Step S202, if an elevator call response sent by an elevator controller is obtained within a preset time, waiting for obtaining elevator in-place requests sent by the elevator controller through a 4G communication link and a LoRa communication link respectively, wherein the elevator in-place requests carry unique in-place numbers;
specifically, the delivery service robot waits for an elevator call response from the elevator controller all the time, when the elevator call response sent by the elevator controller is received within 100 milliseconds (that is, within a preset time, the embodiment of the present invention does not specifically limit the preset time), which indicates that the delivery service robot successfully requests elevator resources, when the elevator car moves to the floor where the delivery service robot is located, the elevator controller actively sends an elevator in-place request to the delivery service robot (the sending method is similar to the sending method of the elevator call request sent by the delivery service robot, except that the main body of the earlier-sent request is the elevator controller), and the delivery service robot waits for the elevator in-place request sent by the elevator controller through the 4G communication link and the LoRa communication link, respectively.
Step S203, after an elevator in-place request sent by an elevator controller is obtained, an elevator in-place response is sent to the elevator controller through a 4G communication link and a LoRa communication link respectively, wherein the elevator in-place response carries the same in-place number as the corresponding elevator in-place request;
specifically, after the distribution service robot acquires an elevator in-place request sent by the elevator controller, the in-place request is processed in a manner similar to the manner of processing an elevator call request by the elevator controller. Specifically, the distribution service robot only processes the data packet of the first arriving elevator in-place request, and only processes the data packet of the elevator in-place request of the 4G communication link if two data packets arrive at the same time, and discards the data packet of the other elevator in-place request with the same in-place number. The dispatch service robot codes the response to the current elevator in-place request (i.e., the elevator in-place response) with the same in-place number as the current elevator in-place request and sends it to the elevator controller over the two communication links.
Step S204, after sending the elevator in-place response, sending an elevator door opening request to an elevator controller through a 4G communication link and a LoRa communication link respectively, so that after receiving the elevator door opening request, the elevator controller sends the elevator door opening response to a distribution service robot through the 4G communication link and the LoRa communication link respectively, and controls the elevator to execute door opening action according to the elevator door opening request, wherein the door opening number carried by the elevator door opening request is larger than the calling number by a preset value, and the elevator door opening response carries the same door opening number as the corresponding elevator door opening request;
specifically, after the delivery service robot answers the elevator in-place request of the elevator controller, the delivery service robot sends an elevator door opening request to the elevator controller through the 4G communication link and the LoRa communication link respectively (the sending mode is similar to the flow and the elevator call request), and the elevator controller processes the elevator door opening request in a manner similar to the elevator call request processing mode.
And after receiving the elevator door opening request, the elevator controller sends an elevator door opening response to the distribution service robot through the 4G communication link and the LoRa communication link respectively, and controls the elevator to execute door opening according to the elevator door opening request.
Specifically, the elevator controller only processes the data packet of the first arriving elevator door opening request, and only processes the data packet of the elevator door opening request of the 4G communication link if two data packets arrive at the same time, and discards the data packet of the other elevator door opening request with the same door opening number. The elevator controller codes the response of the current elevator door opening request (namely the elevator door opening response) with the same door opening number as the current elevator door opening request, sends the response to the distribution service robot through two communication links, and controls the elevator to execute the door opening action according to the elevator door opening request.
Specifically, the preset value may be 1, and the preset value is not specifically limited in the embodiment of the present invention.
The problem of the numbering of the communication packets according to the invention is explained below as follows: 1. each request is the same as the number of the corresponding response; 2. the numbers of the request sent from the distribution service robot and the request sent from the elevator controller are independent, for example, after the elevator controller sends an elevator in-place request with the in-place number 3, the distribution service robot can also send an elevator door opening request with the door opening number 3, and in the current system, the two bodies of the distribution service robot and the elevator controller obviously do not confuse the two requests; 3. the numbers of the requests sent by the distribution service robot are different, for example, the door opening number of the elevator door opening request is different from the call number of the elevator call request; the numbering differs between the requests issued by the elevator controller.
And S205, acquiring an elevator door opening response sent by the elevator controller, and then entering the elevator cage.
Specifically, after the elevator door is opened, the distribution service robot enters the elevator cage.
In an optional embodiment of the invention, the method further comprises:
and if the elevator call response sent by the elevator controller is not obtained within the preset time, returning to the step of sending the elevator call request to the elevator controller through the 4G communication link and the LoRa communication link respectively until the elevator call response sent by the elevator controller is obtained within the preset time.
Specifically, if the elevator call response of the elevator controller is not received within 100 ms (i.e., within the preset time), the distribution service robot performs step S201 again with the same call number. After receiving the repeated elevator call request, the elevator controller sends the elevator call response sent in the first time again. If the distribution service robot receives the elevator call response of the elevator controller within 100 milliseconds again, the elevator call request session is judged to be ended, otherwise, the previous retransmission process is continued until the elevator call response of the elevator controller is received.
The interaction between the dispatch service robot and the elevator controller is shown in fig. 3 by way of a signaling diagram.
The structure of the communication link is described below:
referring to fig. 4,4G a device of a communication link includes: the system comprises a 4G terminal arranged on an elevator controller, the Internet and a 4G terminal arranged on a delivery service robot;
the device of LoRa communication link includes: the system comprises an LoRa communication node device arranged on an elevator controller and an LoRa communication node device arranged on a delivery service robot;
the device of the bluetooth communication link comprises: the Bluetooth slave device is arranged on the elevator controller, and the Bluetooth master device is arranged on the distribution service robot.
In the implementation, when the distribution service robot needs to take the elevator, the distribution service robot moves outside the elevator to the elevator door, and the elevator call request is independently sent to the elevator controller on the elevator car through the two communication links of 4G, loRa. The elevator controller opens two independent threads to process the communication of the two communication links respectively, and does not know the existence of the other communication link. Symmetrically, the distribution service robot body is also provided with two independent threads for respectively processing the communication of the 4G link and the LoRa link.
The communication mode of the distribution service robot and the elevator controller is as follows: the distribution service robot sends an elevator call request once, and the elevator controller responds to the elevator call request after receiving the elevator call request. Each elevator call request is programmed with a different identification number (i.e. call number) and the response to each elevator call request is programmed with the same call number (i.e. identification number) as the corresponding elevator call request. Each elevator call request is issued simultaneously over two communication links, but the specific request loads of both links have the same identification number. An elevator call request arriving first at the elevator controller is accepted and an elevator call request arriving later at another communication link with the same identification number is discarded. After processing the elevator call request, the elevator controller symmetrically codes the response of the elevator call request (i.e. the elevator call response) with the same identification number as the elevator call request, and then sends the response to the delivery service robot independently by dividing into two links of 4G, loRa. The dispatch service robot handles the elevator call response in a similar manner as the elevator controller handles the elevator call request. After the elevator controller has sent the response of the current elevator call request, it immediately executes the action accordingly according to the processing result for the elevator call request.
The two bodies of the present invention comprise: a distribution service robot and an elevator controller. The internet is simply the communication medium between the dispatch service robot and the elevator controller. Data exchange is carried out between the distribution service robot and the elevator controller through three communication links, and the 4G communication link and the LoRa communication link are used for calling an elevator outside the distribution service robot; the bluetooth communication link is used for data exchange between the service robot and the elevator controller in the elevator car and is connected with bluetooth.
In the invention, the distribution service robot and the elevator controller are both provided with 4G terminals (namely terminal equipment of a 4G mobile network), and the distribution service robot and the elevator controller form a communication link through the Internet. While the distribution service robot and the elevator controller are each provided with a LoRa communication node device, the two nodes exchange data by transmitting electromagnetic wave signals to each other point-to-point without an infrastructure such as a base station. Ideally, only the two communication node devices are needed to complete the establishment of the LoRa communication link, and if necessary, an LoRa signal relay node device may be installed at a suitable position in the room to prevent the attenuation of the LoRa signal (i.e., the LoRa communication link includes an LoRa communication node device installed at the elevator controller, an LoRa communication node device installed at the delivery service robot, and an LoRa signal relay node device installed in the room).
In addition to this we note that the dispatch service robot and the elevator controller also take the role of bluetooth master and slave, respectively. The master and slave devices are used to establish a bluetooth communication connection between the dispatch service robot and the elevator controller.
