  • Publication number: 20170042399
    Abstract: A self-moving sweeping device comprises a device body and at least two movement wheels and a direction change wheel located at the bottom of the device body. The direction change wheel includes a magnetic element which is turnable therewith and has a first magnetic pole and a second magnetic pole that are repulsive against each other in magnetism. The device body includes a magnetic induction unit faced the direction change wheel. During movement of the device body the magnetic induction unit detects in normal conditions whether the first magnetic pole has generated a detection signal sent to a behavior control module which determines whether the self-moving sweeping device moves abnormally based on whether the detection signal has been continuously received within a monitor time; if positive, judges the self-moving sweeping device moves normally; otherwise, abnormally.

  • Patent number: 9138116
    Abstract: A movement operation system for autonomous moving cleaning apparatus comprises a virtual wall apparatus and an autonomous moving cleaning apparatus. The virtual wall apparatus includes an infrared ray emitter. The autonomous moving cleaning apparatus includes an infrared ray receiver and a microcontroller unit. The infrared ray emitter emits at least one encrypted infrared signal within an emission zone. When the autonomous moving cleaning apparatus enters the emission zone and the infrared ray receiver receives the encrypted infrared signal, the microcontroller unit controls the autonomous moving cleaning apparatus to move away from the virtual wall apparatus. The encrypted infrared signal can be encrypted in different codes or operating frequencies to prevent the autonomous moving cleaning apparatus from being interfered by external lights or other infrared rays so that it can operate steadily.

  • Patent number: 8744662
    Abstract: A method for operating an autonomous moving cleaning apparatus includes the steps of: a microcontroller unit (MCU) processes a digital signal through an encoding technique to form an encrypted encoding data set; the MCU continuously sends out the encrypted encoding data set; data values in the encrypted encoding data set are converted to high or low voltages to activate a light emission member to generate flicker light; a light receiving member continuously receives a string of reflective light corresponding to the flicker light to form a corresponding high or low voltage which is converted to a corresponding digital signal sent to the MCU to be compared with the encrypted coding data set for decoding; and the MCU controls operations of a servomotor based on decoding correctness and the detected corresponding digital signal. Thus the autonomous moving cleaning apparatus can function steadily without being interfered by external lights.
