The ultrasonic wave in the ultrasonic sensor is a sound wave in a certain frequency range, and the propagation efficiency of an ultrasonic signal with the frequency of 40kHz in the air is optimal. The wave velocity is typically taken (332, 335) as a function of temperature. (ii) a The common ultrasonic sensor with the center frequency of 40kHz and the ranging range within 5m is selected. The sensor transmitting probe and the sensor receiving probe are preferably arranged right in front of the garbage can, when the system works, accurate 40kHz transmitting pulses are generated through a P3.7 port through an assembler, a group of pulses are transmitted every 25ms, the number of the pulses in each group is 6-10, and therefore the transmitting waves are guaranteed to have good spreading performance and reflectivity. The transmitted wave meets the obstacle and is reflected back, the transmitted wave is received by the receiver and is converted into electric signal pulse, the signal is amplified, filtered, compared, shaped and the like and then is sent into an external fracture INT 1 of the single chip microcomputer, the external interruption of the single chip microcomputer is triggered, an interruption processing program is started, the time interval when the transmitted wave is sent to the reflected wave is obtained, namely the distance measuring time, and therefore the distance of the obstacle can be calculated according to the ultrasonic distance measuring principle. The minimum distance from the garbage can to the obstacle in the moving process is set in the main program, and when the measured distance is smaller than the minimum distance, the controller sends an obstacle avoidance instruction to the driving system to avoid the obstacle. In the design, the misoperation caused by crosstalk is removed by software delay, namely, after the transmitted wave is sent for a period of time, the external interruption is opened, so that the phenomenon that the transmitted wave is directly received by a receiver without being reflected to cause false interruption is avoided.

When the system works, a control signal output by the port P1 of the singlechip is input into a motor driving chip L298N through a driver chip 74HC245 to control the motor to act. When the speed is required to be adjusted, the duty ratio of PWM waves (generated by ports P1.3 and P1.6 of the singlechip in the design) is only required to be changed, and 256-level speed adjustment can be realized theoretically.

After the structure is adopted in the utility model, whole box can automatic receiving intelligent terminal's infrared signal to carry the garbage bin and advance towards intelligent terminal direction. The infrared reflection type sensor on the box body can automatically measure the distance between the infrared reflection type sensor and the intelligent terminal, and the ultrasonic sensor on the mobile trolley can automatically avoid obstacles, so that the mobile trolley can smoothly move to the direction of the intelligent terminal and further approach a user; when a user delivers garbage, the user operates corresponding software through an intelligent terminal to select a required garbage can, an upper computer sends a lifting command to a control main board through a communication module, the control main board processes data and then sends the lifting command to corresponding first electric push rod and second electric push rod relays to be attracted, and the first electric push rod and the second electric push rod extend out to lift the garbage can; then through the corresponding software of intelligent terminal operation, the host computer sends through communication module and deflects and or rotatory order to the control mainboard, and after control mainboard processing data, send and deflect and or rotatory order to corresponding deflection motor driver and or rotating electrical machines driver and get electric, drive this dustbin and deflect and or rotatory for the face is thrown towards the user in throwing of this dustbin, and the angle of being close to user and better throwing rubbish that can be more nearly, the person of facilitating the use throws rubbish.

Compared with the prior art, the utility model provides a pair of intelligent garbage can, whole box can automatic receiving intelligent terminal's infrared signal to carry the garbage bin and advance towards the intelligent terminal direction.
