Problems solved by technology

[0002] At present, there are few domestic researches on the smart follow-up system of suitcases, so there is no such follow-up suitcase sold in the market, and the domestic smart follow-up system is not mature enough, most of them still stay in the bluetooth control and use the camera to control the position. The machine captures some behaviors of different people to track specific targets, but these are not very practical in suitcases and cannot be put into normal applications in daily life

Embodiment 1

[0036] Example 1, such as Figure 1-5 As shown, a UWB-based automatic speed-adjusting follow-up and obstacle-avoiding suitcase includes a box body, including a control system installed in the box body and a drive device electrically connected to the control system, a UWB follow-up system and a power supply system; The driving device is installed on the universal wheel at the bottom of the box; the UWB following system includes a signal transmitting end composed of UWB tags placed on the human body and a signal receiving end composed of UWB base station groups installed on the box body; the power supply system is The driving device and UWB follow the system for power supply.

[0037] The UWB base station group includes two left and right UWB base stations side by side on the front of the box and one UWB base station on the back of the box. The three are at the same level as the signal receiving end and are distributed in an equilateral triangle. The distance between adjacent t...

Embodiment 2

[0051] Embodiment 2, the difference between this embodiment and Embodiment 1 is that, on the basis of Embodiment 1, it also includes a fingerprint unlocking module electrically connected to the control system, and the fingerprint unlocking module includes a fingerprint identification module installed on the box Module 13, fingerprint matching module and deceleration motor, the deceleration motor is connected with the combination lock 4 positioned at the side of the casing. The fingerprint identification module is placed at the top of the box at a distance of 5cm from the right side of the pull rod. The fingerprint information is received by the fingerprint identification module and sent to the control system. The control system makes a matching judgment through the fingerprint matching module. When the fingerprints are matched, the deceleration motor is controlled to rotate and open password.

Embodiment 3

[0052] Embodiment 3. The difference between this embodiment and Embodiment 1 is that, on the basis of Embodiment 1, it also includes an anti-theft alarm device electrically connected to the control system. The anti-theft alarm device includes an infrared detector installed at the bottom of the box. The distance module 17 and the buzzer installed on one side of the casing at a distance of 30 cm from the bottom of the suitcase, the infrared distance measuring module 17 is composed of an infrared signal transmitting end and an infrared signal receiving end.

[0053] The installation position of the infrared ranging module is 55mm away from the ground, the operating voltage is 3.3v-5.0v, and the detection distance is 10cm. It has a pair of infrared signal transmitters and infrared signal receivers, and the infrared signal transmitter emits infrared rays. When the detection direction encounters the reflective surface, the infrared ray is reflected back and received by the infrared s...

Abstract

The invention discloses an automatic-speed-regulation following obstacle-avoiding traveling case based on UWB (Ultra-wide Bandwidth), which comprises a case body, a control system arranged in the casebody, and a drive device, a UWB following system, an obstacle-avoiding system, a fingerprint unlocking module, a burglar alarm device and a bluetooth module electrically connected with the control system, and further comprises a power supply system for supplying power for various electrical apparatus elements. The device can be used for omni-directionally and accurately following a specific moving target within a 500m range. The invention also discloses a following algorithm of the traveling case. The device can be used for realizing intelligent obstacle avoiding according to feedback information of the obstacle-avoiding system, so that the traveling case is protected; the device can be used for regulating speed, and the following speed can be adjusted according to changes of the speed ofan owner, so that the practicability in intelligent following is higher; the device is provided with a double-protection system, which comprises a fingerprint recognition device arranged on the sideof the traveling case so as to be prevented from being opened by others, and an ultrasonic sensor arranged on the top end of the traveling case so as to avoid obstacles such as a human body and otherobjects.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a UWB-based suitcase with automatic speed regulation following and obstacle avoidance and a following algorithm. Background technique [0002] At present, there are few domestic researches on the intelligent follow-up system of suitcases, so there is no such follow-up suitcase sold in the market, and the domestic intelligent follow-up system is not mature enough, most of them still stay in the bluetooth control and use the camera to control the position. The machine captures some behaviors of different people to track specific targets, but these are not very practical in suitcases and cannot be put into normal applications in daily life. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned technologies, the present invention provides a suitcase and a following algorithm based on UWB-based automatic speed regulation follow an...
