The worm 1421 is connected to the driving unit 141, and the driving unit 141 is used for driving the worm 1421 to rotate.

The transmission 142 may be an existing transmission 142, such as a belt drive or a worm 1421 drive. The driving unit 141 drives the pointer 13 to rotate on the display member 12 by the transmission 142.

In order to control the degree of rotation of the worm 1421 and thus the number of N values of the counter, a micro control module 155 is provided. Since the energy storage management module 154 converts the wireless waves into energy and supplies the energy to the driving unit module 153, the micro control module 155 controls the energy storage management module 154 to control the current value (i.e. the current between the M-a and M-B electrodes in fig. 3) output from the energy storage management module 154 to the driving unit 141. The current value output to the control driving unit 141 can be customized through the capacitance type selection of the related circuits of the energy storage management module 154, so as to control the rotation degree of the driving unit 141. The value of the current output to the drive unit 141, in turn, controls the degree of rotation (the angle of rotation g) of the worm 1421, and thus the count of the rotation (the angle of rotation c) of the hand 13. Where c ═ G × L/G (L ═ the number of teeth of the worm wheel 1422, and G ═ the number of teeth of the worm 1421). The number N of the counter is 360 °/c. This deduces the value of c, which is a value that can be controlled by controlling the current value output to the driving means 141, thereby controlling the number of N values and realizing the number of N values of the reconfiguration counter.

Specifically, as shown in fig. 2, a counter with N-16 is taken as an example, wherein the periphery of the display member 12 displays 1-16, and each increment of 1 count indicates that the needle rotates by an angle c of 360 °/16 of 22.5 °. If a drive unit 141 with L/G of 5 is selected, the worm 1421 need only be rotated by G of 4.5 ° each time. Therefore, the corresponding driving unit 141 can be set in advance according to system requirements, the value of the L/G can be customized, and the current value output to the driving unit 141 is controlled by the micro-control module 155, so that the angle of G is controlled, the angle of c is controlled, the N value is controlled finally, and the N value of the reconstructed counter is realized.

As shown in fig. 6, the user confirms the identity and the authority on the app or applet of the mobile phone 2, transmits corresponding information to the NFC control module 15 through the NFC wireless communication, and then the energy storage management module 154 of the NFC control module 15 converts the signal into the energy storage current to the driving unit module 153. At the same time, the current value transmitted to the driving unit 141 is controlled by the micro control module 155. Thereafter, the pointer 13 is driven by the driving unit 141 to rotate on the display member 12, starting counting. In addition, the desired number of counter N values may be set by the app or applet of the mobile phone.

In practical use, taking the entrance guard flow rate statistic as an example, the user inputs a password on the app of the mobile phone 2 or uses the existing authority in the applet, and when the mobile phone 2 scans and opens the door by using NFC wireless communication, the NFC control module 15 of the counter is started.
