A battery 109 is mounted on the top of the second support frame 107 through a fixing frame, a bracket 110 is mounted on the top of the second support frame 107, the first support frame 106, the second support frame 107 and the bracket 110 are all inside the housing 102, a mounting plate 111 is mounted on one side of the bracket 110, a speech recognition module 112 and a language processing module 113 are mounted on one side of the mounting plate 111, a display screen 114 is mounted on the housing 102, and a display end of the display screen 114 is movably connected to the housing 102. Inside the hole, a shell 115 is installed on the top of the shell 102, and two symmetrical voice collection modules 116 are movably penetrated through the inner wall of the shell 115. A connecting plate 117 is installed between the opposite sides of the two voice collection modules 116, and the connecting plate 117 is located inside the shell 115. A camera 118 is installed on the inner wall of the shell 115, and the detection end of the camera 118 is movably sleeved inside the circular hole of the shell 115. A porous plate 119 is installed at the inspection port of the shell 102, and a distance sensor 120 is installed on the top of the bottom plate 103. The detection end of the distance sensor 120 is located at the opening of the base 101. A power module 121 and a button switch 122 are installed on the base 101. The electric wheel assembly 104, the battery 109, the voice recognition module 112, the language processing module 113, the display screen 114, the two voice collection modules 116, the camera 118, the distance sensor 120, the power module 121 and the button switch 122 are all electrically connected to the control board 108.

[0040] In this embodiment, when the service robot needs to be used, the service robot is started by using the battery 109 and the button switch 122 (the control board 108 is powered on and starts to be loaded and used, and the components connected to the control board 108 are also powered on and loaded and used). When the service robot is started, the control board 108 controls the electric wheel assembly 104 to start. At this time, the started electric wheel assembly 104 will drive the entire service robot to move from the charging area to the service area according to a pre-set route with the cooperation of the two auxiliary wheels 105. At the same time, when the service robot moves, the camera 118 and the distance sensor 120 will also collect image data and distance data at all times. The control board 108 will collect image data and distance data each time in the form of electrical signals, and then the control board 108 will analyze and compare the received image data and distance data with the distance threshold value set in advance by the control board 108 and the image data stored in advance by the control board 108. When the image data received by the control board 108 detects an obstacle and the distance between the obstacle and the robot is less than the distance threshold value set in advance by the control board 108, the control board 108 will first pause the electric wheel assembly 104, then adjust the roller on the electric wheel assembly 104, and then start the electric wheel assembly 104, so that the service robot can bypass the obstacle and continue to move towards the service area. When the service robot arrives at the service area, the control panel 108 will pause the electric wheel assembly 104, turn off the camera 118 and the distance sensor 120, and let the service robot stop in the service area. When someone stands in front of the service robot and asks a question, the voice collection module 116 of the service robot will collect the voice of the consultant and convert it into an electrical signal to transmit to the control panel 108. Then the control panel 108 will analyze and process the collected language (recognize the vocabulary, grammar and semantics therein) through the cooperation of the voice recognition module 112, and convert the data obtained after the analysis into text information. Then the control panel 108 will use the language processing module 112 to collect the voice of the consultant and convert it into text information. The control board 108 will query the answer to the corresponding question based on the intention and demand obtained after the analysis and processing by the language processing module 113, and then transmit the answer to the question to the display screen 114 in the form of an electrical signal, and then display it on the screen of the display screen 114 for the consultant to view. When it is necessary to charge the battery 109, the power module 121, the prepared charging cable and the external power supply can be directly used to charge the battery 109.

[0041] The effect and working principle of the whole mechanism are as follows: when the service robot is needed, the control panel 108 is first turned on by using an external power supply, and then the use program, distance threshold (the shortest distance to obstacles) are set, and image data (used to detect whether there are obstacles in front of the service robot), moving route (the route of the service robot from the charging area to the service area), disinfection route (the place where the service area needs to be disinfected) and the valve opening and closing angle of the electric regulating valve 207 are stored in the storage of the control panel 108. When everything is ready, the service robot is started by using the cooperation of the battery 109 and the button switch 122 (at this time, the control panel 108 is powered on and starts to load and use, and the components connected to the control panel 108 are also powered on and added). When the service robot is started, the control board 108 will control the electric wheel assembly 104 to start. At this time, the started electric wheel assembly 104 will drive the entire service robot to move from the charging area to the service area according to a preset route with the cooperation of the two auxiliary wheels 105. At the same time, when the service robot moves, the camera 118 and the distance sensor 120 will also collect image data and distance data at all times, and transmit the image data and distance data collected each time to the control board 108 in the form of electrical signals. Subsequently, the control board 108 will analyze and compare the received image data and distance data with the distance threshold value set in advance by the control board 108 and the image data stored in advance by the control board 108. When the control board 108 receives When the received image data detects an obstacle and the distance between the obstacle and the robot is less than the distance threshold set in advance by the control panel 108, the control panel 108 will first pause the electric wheel assembly 104, then adjust the roller on the electric wheel assembly 104, and then start the electric wheel assembly 104 to allow the service robot to bypass the obstacle and continue to move toward the service area. When the service robot arrives at the service area, the control panel 108 will pause the electric wheel assembly 104, turn off the camera 118 and the distance sensor 120, and let the service robot stop in the service area. When someone stands in front of the service robot and asks a question, the voice collection module 116 of the service robot will collect the voice of the consultant and convert it into an electrical signal for transmission to the control panel. The control board 108 will then analyze and process the collected language (identify the vocabulary, grammar and semantics therein) through the cooperation of the speech recognition module 112, and convert the data obtained after the analysis and processing into text information. Then the control board 108 will analyze and process the text output by the speech recognition module 112 through the cooperation of the language processing module 113 (determine the user's intention and needs through operations such as part-of-speech tagging, named entity recognition, and semantic analysis). Then the control board 108 will query the answer to the corresponding question based on the intention and needs obtained after the analysis and processing by the language processing module 113, and then transmit the answer to the question to the display screen 114 in the form of an electrical signal, and then it will be displayed on the screen of the display screen 114.For the consultant to view, when the battery 109 needs to be charged, the power module 121, the prepared charging line and the external power supply can be directly used to charge the battery 109. When the service area needs to be disinfected, the staff can use voice to let the service robot understand the service command. When the service robot receives the instruction that the service area needs to be disinfected, the control panel 108 will move the service robot to the place where disinfection is required through the electric wheel assembly 104, the two auxiliary wheels 105 and the disinfection route pre-set by the control panel 108. When the service robot moves to a place that needs to be disinfected, the control panel 108 will pause first. The electric wheel assembly 104 stops the service robot from moving, and then the control board 108 starts the electric push rod 203. At this time, the started electric push rod 203 will drive the fixed ring 204 to move with the cooperation of the two stable seats 202 and the corresponding rectangular ring 201 connected thereto, and the moving fixed ring 204 will drive the electric regulating valve 207 and the atomizing nozzle 206 to move at the same time through the cooperation of the liquid outlet pipe 205. When the atomizing nozzle 206 moves to a suitable position, the control board 108 will pause the electric push rod 203, and then open the electric regulating valve 207 and the centrifugal pump 210. At this time, the started centrifugal pump 210 will extract the disinfectant in the liquid storage tank 209 with the cooperation of the liquid inlet pipe 211 connected thereto. Then it is transported to the inside of the first hose 208, and then to the inside of the opened electric regulating valve 207, and then to the inside of the liquid outlet pipe 205, and then to the inside of the atomizing nozzle 206, and finally, through the cooperation of the atomizing nozzle 206, it is atomized and sprayed on the place that needs to be disinfected, that is, the atomized disinfectant is used to disinfect the object. When the service robot completes a disinfection operation, the control board 108 will reset the atomizing nozzle 206 through the cooperation of the electric push rod 203, and at the same time close the electric regulating valve 207 and the centrifugal pump 210, and then move to the next place to be disinfected, and then repeat the above steps to disinfect the object again, and repeat this way to disinfect the place that needs to be disinfected. Operation, at the same time, with the cooperation of the second hose 212, the three-way pipe 213, the pipe cover 216, the one-way valve 214 and the filter 215, it can be ensured that the disinfectant in the liquid storage tank 209 is normally drawn out. When the service robot returns to the charging area and new disinfectant needs to be injected into the liquid storage tank 209, the staff needs to first remove the L-shaped block 4 from the hollow block 3.
