Embodiment
Now by reference to the accompanying drawings, the utility model embodiment is described in detail in detail:
As shown in Figure 1 and Figure 2, a kind of utilize mobile device to realize wrist-watch that Self-regulation track pointer realizes time calibration in network, includes pointer 1, button 2, table mirror 4, watchcase 5, PCB 6, battery 9, bottom 11; Watchcase 5 and bottom 11 are interlockingly connected formation one cavity, and PCB 6 is located in cavity; Table mirror 4 is located on watchcase 5; Pointer 1 is connected with the pointer quartz movement in PCB 6, and button 2 is located on watchcase 5, and is connected with PCB 6; The below of PCB 6 is located at by battery 9, and is connected with PCB 6; PCB 6 is provided with bluetooth module 8, and bluetooth module 8 is connected with PCB 6; Institute's watchcase 5 is provided with water proof ring 10 with the junction of bottom 11.
As shown in Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, the utility model PCB 6 comprises MCU circuit A, key circuit B, clock circuit C, reset circuit D, pointer motor drive circuit F, bluetooth module circuit G, key information is sent to MCU circuit A by key circuit B, clock circuit C transmission clock signal is to MCU circuit A, reset circuit D transmits reset signal to MCU circuit A, and MCU circuit A transmission signal drives pointer 1 displaying time to pointer motor drive circuit F; MCU circuit A transmission signal communicates with the bluetooth on mobile device to bluetooth module circuit G.
MCU circuit A: according to various input signal, carries out arithmetic, logical operation, Machining Analysis, outputs signal to pointer 1 instruction time, bluetooth module transmission or reception data.
Key circuit B: input various user instruction to MCU circuit A.
Clock circuit C: provide stable clock signal to MCU circuit A.
Reset circuit D: provide reliable reset signal to MCU circuit A.
Pointer motor drive circuit F: accept MCU circuit a-signal, drives pointer 1 instruction time.
Bluetooth module circuit G: accept MCU circuit a-signal, transmits or receives data.
At normal state, each element circuit is in sleep state, reaches energy-conservation object.MCU circuit A retention time function, MCU circuit A sends temporal information to pointer motor drive circuit F information instruction time; Pointer motor drive circuit F shows current time.
Send correction point instruction when MCU circuit A receives key circuit B, MCU circuit A sends instruction to pointer motor drive circuit F, and pointer motor drive circuit F stops taking the needle, and waits for school pin.MCU circuit A starts the communication between bluetooth module circuit G immediately, and send a command signal to bluetooth module circuit G, bluetooth module circuit G is activated, the current pointer clock position that the bluetooth module circuit G bluetooth be used on reception mobile device sends over, minute position, second hand position, if receive successfully or time-out failure, bluetooth module circuit G return message is to MCU circuit A, MCU circuit A, according to returning results, sends school pin signal and corrects pointer to pointer motor drive circuit F.MCU circuit A sends instruction to bluetooth module circuit G simultaneously, allows it get back to sleep state.
Time calibration in network instruction is sent when MCU circuit A receives key circuit B, MCU circuit A starts the communication between bluetooth module circuit G immediately, and send a command signal to bluetooth module circuit G, bluetooth module circuit G is activated, the current network time that the bluetooth module circuit G bluetooth be used on reception mobile device sends over, if receive successfully or time-out failure, bluetooth module circuit G return message is to MCU circuit A, MCU circuit A, according to returning results, sends time signal to pointer motor drive circuit F information instruction time; MCU circuit A sends instruction to bluetooth module circuit G simultaneously, allows it get back to sleep state.
