Sd, and after a preset time, for example, after 3 minutes, the wireless transmission interface 22 is set to enter the power saving mode. Before the second=material signal Sd, the wireless transmission interface 22〇 is set to the power saving mode, and the power consumption of the GPS receiving device can be set. Then, the signal receiving unit 210 in the step coffee towel is sent (10) the data signal s back to step 310, and continues to set the wireless transmission interface to be in a power saving state. The signal receiving unit 210 will transmit the G 杈 type. The right signal receiving unit 21G uses the d'_step, and the interface 22 〇 enters the continuous working mode switching signal Sw to control the wireless communication device 230. Finally, in 1 / Yun (10) Bayesian signal Sd to no * no transmission is completed, if not, then; in H mode to transmit GPS f material _ m === 350' set wireless transmission interface 22 〇 restore to The second electrical mode can also be the same as the power saving mode before transmitting the GPS data. In the above-mentioned step 330, the signal receiving unit 2 uses the mode switching signal ^ to control the wireless transmission switching operation, 'the following two examples are used for explanation', but the present invention is 8 1286899

- Sanda number: TW2704PA is here. First Example Referring to Figure 4, it is shown that the operation timing chart is switched in accordance with the operation mode of the present face 220. - The example wireless transmission is transmitted at a fixed period, for example, the above-mentioned _屮 and "PS data signal%" is a period of a second of the data signal Sd. : ―: owed: Figure 4 is the transmission and reception unit 21 〇 transmission GPS data signal Sd brother ^ shown in the signal and the ancient cage one, 隹 from T to switch the signal Sw; power saving " A low level, at this time, the wireless transmission interface 220 is at the power mode. When the signal receiving unit adds the Gp -21〇s:^S„d 3 U to the second level L2 (for example, the high level), that is, the rising edge (R position) To control the wireless transmission interface 22::=, then transmit the GPS data (10). Therefore, the transmission signal is opened. The time tl will be later than the signal Sw switching time point τι. Later, When the wireless transmission interface 220 is in the continuous working mode, the working die changer Sd is maintained at the second level L2. After the signal receiving unit 2 (7) transmits the GPS data signal Sd at the intermediate point t2, the signal receiving unit (4) Convenient to switch the signal Sw from the second level L2 to the first level, ie, the Falling Edge method is used to control the wireless transmission interface to the power saving mode. The timing switch point T2 of the signal Sw is later than the end time point t2 of the special number S d. This ensures that the wireless transfer interface 220 can transmit the gpS data signal sd to the wireless communication device 230 in the continuous operation mode. Avoid the problem of transmission errors. 9 1286899
