This follow shopping cart based on ultrasonic wave and infrared induction, including the automobile body, power wheel and leading wheel are installed to the bottom of automobile body, and the leading wheel adopts the universal wheel, and the internally mounted of automobile body has detection drive arrangement, and the outside of detecting drive arrangement is covered with the collision avoidance shell. Detecting drive arrangement and including control chip, control chip is last to be linked has the bluetooth equipment, alarm devices, check out test set and motor drive equipment, and handheld bluetooth equipment, motor drive device driver step motor are connected to the bluetooth equipment. The check out test set includes ultrasonic sensor and infrared inductor, and wherein ultrasonic sensor is towards the rear of automobile body, and infrared inductor is towards the place ahead of automobile body.
Description
Technical field
This utility model relates to shopping cart technique field, is specifically related to a kind of follow shopping cart based on ultrasound wave and infrared induction.
Background technology
Along with the progress of scientific and technical development and human society, intellectualized technology is deepened day by day in daily life, brings great convenience to the life of people.When people remove supermarket shopping, particularly old people, shopping cart can be pulled at any time, when the commodity bought are more, common shopping cart will be very heavy when advancing, and affects people and uses, adds the burden of user, bring bigger inconvenience to the use of user.
Utility model content
The purpose of this utility model is to pull inconvenience for existing shopping cart, the deficiency of inconvenience greatly is brought to the use of user, propose one and pass through step motor drive, set, by the control chip weight according to the commodity inside shopping cart and road conditions, the speed control parameter automatically following shopping cart, follow shopping cart by detecting distance between equipment Inspection detection user and shopping cart a kind of based on ultrasound wave and infrared induction.
This utility model specifically adopts the following technical scheme that
A kind of follow shopping cart based on ultrasound wave and infrared induction, including car body, the bottom of described car body is provided with power wheel and directive wheel, the internally installed of described car body has detection driving device, described detection driving device includes control chip, being connected with bluetooth equipment, warning device, detection equipment and motor driving apparatus on described control chip, described bluetooth equipment connects hand-hold Bluetooth equipment, described motor driving apparatus drive stepping motor.
Preferably, described detection equipment includes ultrasonic sensor and infrared inductor.
Preferably, described ultrasonic sensor is towards the rear of car body, and described infrared inductor is towards the front of car body.
Preferably, the outside of described detection driving device is covered with Anti-bumping protection shell.
Preferably, described directive wheel adopts universal wheel.
This utility model has the beneficial effect that this following shopping cart and can automatically follow user in time and advance based on ultrasound wave and infrared induction, and can keep and the safe distance of user；When user turns left or turns right, the position of ultrasonic sensor by detecting can set the angle of rotation, the size of the anglec of rotation, it is possible to set PWM by control chip and realize motor differential, make shopping cart complete to turn；When user can not be detected, it is possible to send audible alarm in time, remind user to stop, search out the position at shopping cart place and return to the dead ahead of shopping cart, then automatically following shopping cart normal operation；Under emergency case or when road conditions are bad, it is possible to communicated by the control chip of hand-hold Bluetooth equipment Yu this shopping cart, send instruction in time, allow automatic shopping cart stop or to change mode of operation；The combination that can pass through ultrasonic sensor and infrared induction module uses, and applies corresponding control strategy, it is judged that the movement posture of user.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of detection driving device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed description of the invention of the present utility model is described further:
Shopping cart is followed based on ultrasound wave and infrared induction, including car body as it is shown in figure 1, a kind of; the bottom of car body is provided with power wheel and directive wheel; directive wheel adopts universal wheel, and the internally installed of car body has detection driving device, and the outside of detection driving device is covered with Anti-bumping protection shell.Detection driving device includes control chip, and control chip is connected with bluetooth equipment, warning device, detection equipment and motor driving apparatus, and bluetooth equipment connects hand-hold Bluetooth equipment, motor driving apparatus drive stepping motor.Detection equipment includes ultrasonic sensor and infrared inductor, and wherein ultrasonic sensor is towards the rear of car body, and infrared inductor is towards the front of car body.Before wherein infrared inductor is used for judging shopping cart, whether user exists；Motor driving apparatus is for drive stepping motor operating；Warning device is that control chip carries out early warning according to the signal of sensor acquisition and reminds user；Bluetooth equipment is used for communicating between hand-hold Bluetooth equipment.
Should be: under normal mode of operation that automatically following shopping cart can keep keeping straight on user, and control chip sends identical PWM to two-way drive motor, and keeps certain safe distance with user based on the operation principle following shopping cart of ultrasound wave and infrared induction；When the ultrasonic sensor at two ends detects that user turns, the PWM that control chip output two-way is different, make automatically to follow shopping cart two-way motor differential and travelled turning, the gap of two-way PWM depends on the amplitude that user's body rotates, and these can be obtained by the ultrasonic sensor range finding that diverse location is laid；When detection drive equipment Inspection less than the existence of user or user from the distance of shopping cart bigger time, automatically follow shopping cart and halt, control chip can enable alarm module and send audible alarm simultaneously, reminds user to return on tram；When running into emergency case or shopping cart load-carrying is heavier, road conditions have been not as, user can be communicated with control chip in time by hand-hold Bluetooth equipment, allow and automatically follow the mode of operation that shopping cart halts or changes shopping cart, it is ensured that cart security stably travels.
Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, the change made in essential scope of the present utility model of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
