Rotator utilizing RFID technology and provided with spring touch point and rotation duration measurement system and method

[0025] Example 1

[0026] In the embodiment provided by the present invention, the rotating body is a spinning top for sports or toys, such as figure 1 As shown, a gyro rotation duration measurement system with spring contacts using RFID technology includes: gyro body 1; rack 2; competition area base 3; computer terminal and/or mobile smart device APP 4.

[0027] exist Figure 2-4 , the structure of the top body is further disclosed. The top body 1 is composed of a top cover 11, an attack ring 12, a fission ring 13 and a top tip 14. The top cover 11, attack ring 12, fission ring 13 and top tip 14 are arranged from top to bottom connected in turn, in image 3 Among them, the gyro body 1 is provided with an RFID tag and an IC chip 15, and the RFID tag and the IC chip 15 have a ring-shaped antenna 16, and the antenna 16 is stuck between the attack ring 12 and the fission ring 13, and one end of the ring antenna 16 Connect with RFID tag and IC chip 15, the other end is connected with vibration switch 17, the side of vibration switch 17 is provided with the China Unicom contact that matches with RFID tag and IC chip 15, in Figure 4 Among them, the spring mouth of the gyro tip 14 is formed by engaging two symmetrical left and right covers 141, the upper part of the shaft column 142 is fixedly connected with the positioning piece bayonet 143 through the shaft center piece 148, the lower part is covered with a gear 144, and the bottom of the shaft column 142 From top to bottom, a bare body rotating part 145, a fixing cap 146 and a bottom vertebral body tip 147 are fixed by the shaft core part 148.

[0028] Figure 5 It shows the structure of the rack 2, which is composed of a handle and a pull bar. The handle is set on the top of the side of the pull bar, so that the rack as a whole is in the shape of a "T". The inner wall features matching protrusions.

[0029] Image 6 The structure of the competitive area base 3 is shown, the support 31 of the competitive area base is a triangular support, the center of the support 31 is the RFID tag reading area, and the RFID tag reading area is respectively stuck on the top of the support 31 and the lower cover 33 by a transparent material. The bottom forms a hollow area, and the induction antenna 34, PCBA assembly printed circuit board 35, RFID tag reader 36 and battery 37 are installed from top to bottom in the area, and the induction antenna 34, PCBA assembly printed circuit board 35, RFID tag reading The device 36 and the battery 37 are connected in turn.

[0030] The basic working principle of the present invention is that when the gyro is stationary, the vibration switch is disconnected, and the RFID tag is not fully connected with the IC chip and the antenna. At this time, the RFID tag will not be recognized by the RFID reader; Under the action of centrifugal force, the vibration switch is short-circuited, so that the RFID tag is connected with the IC chip and the antenna, and is recognized by the RFID tag reader. The RFID tag reader calculates the gyroscope from static to rotating or vibrating by timing the recognition time. Duration and or period between rotation or vibration cessation. The specific implementation is described as follows:

[0031] when working, such as Figure 1-6 As shown, press and hold the top cover 11 or attack ring 12 of the top body 1, insert the rack 2 into the spring opening of the top body 1, pull out the rack 2 and loosen the top cover 11 or attack ring 12 of the top body 1 at the same time , so that the gyroscope body 1 rotates on the RFID tag reading area of ​​the competition area base 3; since the RFID tag reader 36 is housed, the RFID tag reading area can simultaneously identify multiple RFID tags and IC chips 15 above;

[0032]At this time, because the RFID tag and the IC chip 15 (tag) (passive or active tag) are housed in the gyroscope body 1, each tag has a globally unique ID (GUID), and the tag has a storage function, which can be passed through The radio frequency technology reads and writes the tag; the relevant information of the gyro body 1 is stored on the Tag; the RFID tag reader 36 can identify the gyro body 1 by reading the relevant information of the tag, and transmit it to the computer terminal and, Or display on the mobile smart device APP4;

[0033] Judgment of gyro rotation time:

[0034] like image 3 As shown, when the gyroscope body 1 starts to rotate, because of the centrifugal force, the contact of the vibration switch 17 will be in contact with the RFID tag and the IC chip 15, so that the tag antenna 16 is connected, so it can be read by the RFID tag reader 36 at the bottom. It is recognized that timing starts at this time, and the starting time is ts;

[0035] When the gyroscope body 1 starts to reduce the rotating speed due to external factors, when it is about to stop, due to the loss of the support of centrifugal force, the contact of the vibration switch 17 is disengaged, and the tag antenna 16 is disconnected. At this time, the RFID tag reader 36 at the bottom will If the tag cannot be recognized, the timing ends at this time, and the end time is te. Then the rotation time of the gyroscope Tx=te-ts;

[0036] Bluetooth, infrared, WIFI and other wireless transmission technologies are used to realize data connection, so that the results are displayed on the computer terminal and/or mobile smart device APP 4.
