As shown in fig. 2, an embodiment of the present invention provides a method for disinfecting a toilet, which is implemented by the toilet disinfecting system, and the method includes the following steps:
in step S1, the robot determines the location of the compartment when receiving the information that the infrared sensor in the compartment detects the user entering, and then starts the disinfection program after receiving the information that the user leaves. In the process of performing step S1, the infrared sensor judges the state where the user enters and leaves from the distance value it measures. The measurement value of the infrared sensor in the case of no-person use of the compartment is set to a prescribed value, and when the prescribed value is changed, it indicates that the user enters the compartment, and after the prescribed value is returned to normal, it indicates that the user leaves the compartment. In special cases, if the time interval from the occurrence of the change from the specified value to the return to normal is short, it can be assumed that no person is using the compartment and the robot does not start the disinfection program. When the user is detected to enter the compartment, the robot judges the position of the compartment through the identification code of the infrared sensor.
In step S2, the robot moves to the corresponding compartment and deploys the second robot arm forward, and then controls the second robot arm to rotate in the direction in which the compartment door is opened to push the compartment door open while advancing until the robot enters the compartment. It should be noted that, the public washroom described in the present invention takes a common partition manner as an example, and the partition manner has the following characteristics: the compartment door is generally pushed inwards, the outer side of the compartment door is not provided with a handle, the inner side of the compartment door is provided with a cylindrical handle, and the compartment door is locked by a rotary door bolt on the side, wherein the rotary door bolt is one of key disinfection objects.
In the process of executing step S2, since the environment of the toilet is simple, the robot carries inertial navigation enough to meet the requirement of autonomous movement, and compared with laser navigation, the cost is greatly reduced, and compared with visual navigation, there is no risk of revealing the privacy of the user. The forward deployment of the second robot arm means that the robot rotates the second upper arm 63 forward to be parallel to the ground and then rotates the second lower arm 64 to be perpendicular to the ground. Alternatively, the second mechanical arm may also be deployed forward in other ways, as long as the effect of pushing open the compartment door is achieved. After pushing the compartment door, the infrared sensor can detect the distance from the robot, and the distance can be used for judging whether the robot enters the compartment.
In step S3, the robot opens the camera 51 to detect the door bolt and the flush button and controls the nozzle 52 of the first lower arm 54 to perform spray disinfection. It should be noted that the robot does not deploy the first arm and does not open the camera 51 before entering the compartment, so that the user does not have to worry about privacy disclosure.
In the process of executing step S3, the method for the robot to open the camera 51 to detect the bolt and the flush button and perform sterilization includes: after the robot enters the compartment, the first upper arm 53 is lifted forward until it is parallel to the ground so that the camera 51 on the first lower arm 54 can detect the bolt backwards. It should be noted that the robot is in a standby state when not in operation; in the standby state, the first lower arm 54 and the second lower arm 64 of the robot are retracted upward in the direction of the back of the robot, so that the camera 51 located at the end of the first lower arm 54 can detect the back right after the robot lifts the first upper arm 53 forward. The robot changes the angles of the first upper arm 53 and the first lower arm 54 by the joint motor 55 and collects images while recognizing the keeper using template matching. After identifying the bolt, the robot continues to adjust the position of the camera 51 until the bolt is located in the central area of the image, and then starts the micro-pump 40, so that the spray head 52 sprays the disinfectant to finish the disinfection of the bolt. The robot then deploys the first lower arm 54 forward, continues to capture images and identify and disinfect the flush button using template matching. In the process of identifying the flushing button, the direction of the collected image of the robot can be planned in advance according to the operation environment so as to improve the identification efficiency. As an example of the abnormality processing, when the robot cannot recognize the keeper for a certain period of time, the robot turns to recognize the flush button, and if the robot cannot recognize the keeper for the same time, the process proceeds to step S4.
In step S4, the robot controls the first lower arm 54 to spray disinfectant according to the preset movement track to disinfect the air. In order to guarantee the disinfection quality, after the disinfection of the objects which can be directly touched by the user is finished, the air needs to be disinfected to eliminate the suspended viruses or bacteria. Alternatively, the preset motion trajectory may be a bow shape, a zigzag shape, or the like, without being particularly limited.
And step S5, the robot retracts the first mechanical arm and exits the compartment, then retracts the second mechanical arm, and simultaneously analyzes the use condition of the faucet through the information transmitted by the infrared sensor of the washbasin.
