Further, the information that described microprocessor integrated treatment infrared detecting device and bluetooth positioning chip detect, provide the direct of travel of shopping cart, particularly as follows:
First determine the target location of this time walking according to the location information of bluetooth positioning chip gained, if two infrared detecting devices all do not measure object, front clear is described, it is possible to either directly through；If left infrared detecting device has measured barrier, right does not have, then a segment distance of should first walking to the right, until left infrared detecting device does not detect barrier, then walks towards target direction；If right infrared detecting device measures barrier, left does not measure and processes with same method；If two infrared detecting devices have all measured barrier, then the people in wait front of should stopping or thing are further continued for advancing after removing.
The present invention, compared with background technology, has the beneficial effect that
1, adopt deceleration direct-current motor to drive shopping cart, liberated client's both hands, allow client more flexibly, do shopping freely, supermarket installations hommization more can be made.
2, bluetooth 4.0 technological orientation is adopted to follow the tracks of, it is possible to accurately to mate location with the mobile phone of client, do not worry taking shopping cart or shopping cart by mistake with the problem lost.
Accompanying drawing explanation
The following drawings is only intended to, in the present invention being schematically illustrated and explaining, not delimit the scope of the invention.
Fig. 1 is the overall structure schematic diagram of the present invention；
Wherein: 1. shopping cart body, 2. power supply, 3. infrared detecting device, 4. reducing motor, 5. servomotor.
Detailed description of the invention
As it is shown in figure 1, the present invention includes shopping cart body 1, power supply 2, infrared detecting device 3, reducing motor 4, servomotor 5, control circuit；The left and right support of described shopping cart body 1 is equipped with infrared detecting device 3, for detecting the mankind of close together around and the positional information of goods；Described reducing motor 4 and servomotor 5 are installed on shopping cart body 1, and the output shaft of reducing motor 4 is connected with the trailing wheel of shopping cart body 1；The output shaft of described servomotor 5 is connected with the front-wheel of shopping cart body 1；Described infrared detecting device 3, reducing motor 4 are all connected with control circuit with servomotor 5；Described power supply 2 provides running voltage for whole device.
Described control circuit is made up of microprocessor, bluetooth positioning chip and motor drive ic；Described bluetooth positioning chip is all connected with microprocessor with motor drive ic；Described bluetooth positioning chip for the Bluetooth pairing on client's mobile phone, receive the positional information of client, and this positional information passed to microprocessor；Described reducing motor 4, servomotor 5 are all connected with motor drive ic.
Described microprocessor can adopt the product of Intel company's 80C52 model, but is not limited to this；Described bluetooth positioning chip can adopt the product of Texas Instruments's CC2541 model, but is not limited to this；Described motor drive ic can adopt the product of ST Microelectronics's L298N model, but is not limited to this.
Infrared detecting device 3 detection obtains the mankind of close together around and the positional information of goods, sends information to microprocessor；Meanwhile, bluetooth positioning chip receives the positional information of client, and this positional information is passed to microprocessor；The information that microprocessor integrated treatment infrared detecting device 3 and bluetooth positioning chip detect, first the target location of this time walking is determined according to the location information of bluetooth positioning chip gained, if two infrared detecting devices 3 all do not measure object, front clear is described, it is possible to either directly through；If left infrared detecting device 3 has measured barrier, right does not have, then a segment distance of should first walking to the right, until left infrared detecting device 3 does not detect barrier, then walks towards target direction；If right infrared detecting device 3 measures barrier, left does not measure and processes with same method；If two infrared detecting devices 3 have all measured barrier, then the people in wait front of should stopping or thing are further continued for advancing after removing.Microprocessor sends traveling scheme to motor drive ic, motor drive ic control reducing motor 4 and servomotor 5 and according to the walking of traveling scheme and turn to.
