Embodiment Construction
[0024] The present invention discloses a self-propelled device and a sensor detection method thereof. The self-propelled device can be a robot, a lawn mower, a vacuum cleaner, a sweeper, etc., and the method can be applied to these self-propelled devices for setting Sensors on these self-propelled devices perform detection.
[0025] now refer to figure 1 , figure 1 It is the structural frame diagram of the automatic walking equipment. The autonomous running device includes a judging unit 110 , a timing unit 130 , a control unit 150 and a sensor 200 . The control unit 150 is used to control the judging unit 110 and the timing unit 130 . The judging unit 110 is connected to the sensor 200 and is used to acquire the output signal of the sensor 200 connected thereto. When the sensor 200 detects an external trigger event, it will output a corresponding trigger signal, and the judging unit 110 can judge that the sensor 200 is working normally after receiving the corresponding tr...

The invention relates to an automatic walking apparatus and a detection method for sensors thereof. The method comprises the steps of acquiring output signals of a sensor; starting an automatic detection period; if the sensor outputs a trigger signal in the automatic detection period, determining that the sensor is in a normal state; if the sensor never outputs a trigger signal in the automatic detection period, starting a manual detection period; if the sensor outputs a trigger signal in the manual detection period, determining that the sensor is in a normal state; if the sensor never outputs a trigger signal in the manual detection period, determining that the sensor is not in a normal state; if the sensor is in a normal state, starting the next automatic detection period. The method and a system judge whether a sensor is in a normal state according to whether the sensor is triggered to generate a corresponding signal in an automatic detection period; if the sensor is not triggered in the period, whether the sensor is in a normal state or not is judged through manual detection; through the combination of automatic detection and manual detection, whether a sensor is in a normal state can be detected effectively and the cost is low.
Description
technical field [0001] The invention relates to the field of walking equipment, in particular to an automatic walking equipment and a sensor detection method thereof. Background technique [0002] Intelligent automatic walking equipment is well known to people. Since automatic walking equipment can automatically perform preset related tasks without human operation and intervention, it is widely used in industrial applications and household products. Industrial applications such as robots that perform various functions, and household products such as lawn mowers, vacuum cleaners, sweepers, etc. These intelligent automatic walking equipment greatly save people's time and bring great benefits to both industrial production and home life. Great convenience came. During the use of these automatic walking equipment, in order to improve the safety performance, a number of corresponding sensors are set up to detect the state of the automatic walking equipment itself or the external ...
