As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

Example one

In one or more embodiments, disclosed is an intelligent robot system based on elevator communication, as shown in fig. 1, including: a first control unit MCU1 arranged on the elevator, an RFID (radio frequency electronic tag) transmitting device arranged on an intelligent robot (EIR for short) and a second control unit MCU2 for receiving and processing related data signals; the first control unit MCU1 is communicated with the control system of the elevator, and can be communicated in a wired mode or a wireless mode; in the embodiment, a master-slave distributed serial architecture is adopted, and an elevator control system is a master control unit and is in serial communication with a slave MCU1 and a slave MCU2 through an RS485 bus. Of course, those skilled in the art can select other communication modes according to actual needs.

The second control unit MCU2 and the first control unit MCU1 are in wireless communication, the wireless communication modes are various, such as Bluetooth, a WiFi network, infrared signals and the like, and a person skilled in the art can select a proper communication mode according to the specific working scene of the inspection robot; in this embodiment, the second control unit MCU2 and the first control unit MCU1 communicate with each other through a Wifi adaptor.

In this embodiment, the first control unit MCU1 includes a Si44XX rf chip + M051X serial communication interface chip + package function chip + storage unit.

The first control unit MCU1 can acquire the running state of the elevator, and sends an operation command for controlling the running of the elevator to the elevator control system according to the received position information of the intelligent robot or the addressing task command;

the second control unit MCU2 can send intelligent robot position information to the first control unit MCU 1; receiving a command of a first control unit MCU1, and controlling the intelligent robot to run to an addressing task instruction position;

in order to realize the horizontal addressing location of the EIR, an RFID receiving chip is arranged at a preset position point (hereinafter referred to as a room door area n) of a flat layer, when the EIR walks to the room door area n, the MCU2 receives a signal of the RFID, and if an instruction (such as a parking service instruction) is given in advance, the EIR can park to finish preset services (such as auditory signal and visual signal transmission, response, delivery, alarm and the like), so that the information linkage, data acquisition and storage of the vertical service of the elevator and the horizontal service of the intelligent robot are realized, and the information integration is realized.

It should be noted that the position points in the horizontal layer refer to position points in the horizontal space in each floor in the building; for example, room 1 and room 2 of the 2-storied building belong to different position points in a flat floor; room 1 and room 2 of floor 3 belong to different location points of another flat floor.

EIR addressing positioning is realized by distance self-learning and memorizing the ID address subcodes of the room door regions n through an elevator communication system:

as is known, the RFID has a unique ID code, and a RFID tag is provided at each corresponding n-position of the room door zone, and the tag is identified by a signal having a unique address code. When the EIR receives the instruction to walk through the signal identifications, the RFID reads and writes for response, the received signals can be recorded by the second control unit MCU2 one by one, the signals are sent through the wireless switching device and stored in the first control unit MCU1, and according to a specified coding rule, each ID address code is identified according to the floor and the room door area n where the ID address code is located and represents a unique address. E.g., ID/Fn-01, ID/Fn-02, ID/Fn-n. Since the distance between the room door zones n in the building is completely constant, the ID address code obtained by the EIR by first walking is the addressed parking position at which the EIR will perform the task in the future.

The system sets a process that EIR confirms the position of a room door zone n through an RFID response device for the first time and defines and stores an ID address code signal according to a preset rule, which is called as follows: distance self-learning.

Through distance self-learning, each ID code signal is stored in the MCU1 and is in contact with an elevator communication system, and when an elevator or other wireless modes send an addressing service instruction to the EIR, the EIR can automatically call the elevator to complete door opening, entering, up and down, door opening, exiting, addressing, parking and returning actions. For example, the EIR is given an ID/F10-02 command, the EIR can enter the elevator to 10F, the elevator opens the door, the EIR automatically leaves the elevator, addresses to the ID/F10-02 position, stops, and completes the predetermined action or service.

Referring to fig. 2, an RFID tag is provided in the room door zone n of each floor, and the EIR "self-learns" from the distance between the elevator and the room door zone n from a predetermined initial position: self-learning is performed according to a distance principle, such as: distance mm from F1-01 to F1-02, and so on. Responding and reading and writing the RFID electronic tags arranged in the room door zones n of all the preset service floors until the learning of the ID address codes of all the preset floors is completed; the running track of the intelligent robot reaching each set position point in the horizon can be obtained through distance self-learning.

It should be noted that the EIR addressing task instruction can be sent to the EIR through the elevator, and can also be sent to the elevator remotely through the building internet of things system.

When the elevator is used for sending, a calling device is arranged in the elevator, for example, an operation button can be arranged in the elevator, so that the operation is convenient, the calling device is in contact with an EIR through a communication system of the elevator, the calling device sends an addressing task instruction to a first control unit MCU1 through an elevator main controller, and a first control unit MCU1 sends an addressing task instruction to a second control unit MCU2 through a wireless switching device; the second control unit MCU2 receives the signal and controls the EIR to reach the appointed floor according to the instruction, then the EIR leaves the elevator to move horizontally according to the appointed route to the preset RFID answering position, the EIR addressing is completed, the elevator stops, the preset service is completed, the next preset service is continued to the end, and if no other instruction exists, the elevator automatically returns to the appointed position to stop for standby.

Or appointed personnel can remotely send a task instruction to the elevator in the management control room through a building internet of things system, and the elevator control system controls the EIR according to the communication method after receiving the remote control instruction.

In other embodiments, an automatic recall unit is added on the basis of the disclosed intelligent robot system based on elevator communication, the automatic recall unit can send an automatic recall instruction, and after receiving the automatic recall instruction, the current position information of the intelligent robot is determined according to an ID address code acquired by the intelligent robot; controlling the elevator to reach the floor where the intelligent robot is located according to the position information; and simultaneously, controlling the intelligent robot to return to the elevator taking position and the elevator to return to the preset initial position.
