Π) The identification number (35) is made separately. The new model can also increase the mutual authentication mechanism and reduce the chance of misjudgment. The receiving/alarm circuit (36) in Figure 4 further includes a power switch (24) that is not disposed on the transmitting circuit (37) and is connected to the computer (13) via the USB connector (15) (JSB埠(14) Connect to get power. The RF signal transmission function of the portable dock (12) can be used to prevent the USB connection device (1〇) from being forgotten on the computer (〗 〖Magic USB 淳 (14). When Φ computer (13) When it is suddenly turned off, an alarm 06) is activated to remind the user to remove the USB connection device (1 〇). μ The power supply of the portable base (12) can be supplied by a direct current (DC) power supply (21). The DC power supply (21) can be a battery or a photovoltaic panel or a capacitor. As shown in Figure 4, when the portable base (12) is coupled to the signal device (11) and the USB connection device (1〇), The switch (24) can be turned on (power off) and immediately turned off (power on) when removed. Figure 4 further discloses that an alarm automatic switch (28) can be controlled by the receive/alarm control circuit (34) and It is activated by a signal return (38) of the RF signal (2〇). A manual alarm switch (25) as shown in Figure 1 can be used to turn off the alarm (π In Fig. 4, the alarm M4U3713 S) generated by the alarm generator (26) in the receiving/alarm circuit is dynamic, but can also be (iv) visual or observing alarm. The electricity is more mixed. The present invention uses the sound effect alert 13 as the mode source indication (10). Hong Bao (10) builds whip secret _ reduce money in low power = 3 shown transmission fine) or the receiving / alarm control circuit shown in the figure a selectable - timer (10). In the present invention, the addition of the timer (2) is mainly provided by the J·1·transmission circuit (17)-transmission interval (30). 2. Provide a delay (31) for the receive/alarm circuit (34) to avoid an alarm caused by a missed J (16) ° or when the automatic alarm switch (10) or switch (24) is not installed The USB connection device (10) on (13) is taken before the alarm (10) is started. Figure 5 shows that the transmission interval (10) and the alarm delay (31) delay delay (3) of the two radio signals (10) are longer than the transmission _(10)), and the resident (31) scale _ Separate (10) each, stand the device (23). The purpose of setting the transmission interval (30) is to avoid interference between the radios (10), especially when there are multiple inventions operating simultaneously in a common space. As shown in FIG. 5, two radio signals (10) each having a transmission _(10) of about two seconds have only a small chance of being interfered by the current radio signal (10) between the two tilt intervals (10). Causes signal reception errors. Therefore, the variation of the suggested transmission interval (30) can be controlled by the transmission control circuit (π). As shown in Fig. 5, a random number generator (29) is mounted on the transmission circuit (37). The transmission control circuit (17) can set a random number generated by a small number of random number generators (2) to distinguish the transmission interval (3〇), as in the example of Figure 5, from .75 to 2, 25 seconds. The radio signal (2G) feeds for about a millisecond, plus the transmission of the M403713 interval (30) to avoid collisions or interference between the radio signals (20). When the alarm delay (31) is greater than the transmission interval (30), the loss of the radio signal (20) due to the instantaneous blocking of the device will not cause an alarm. To avoid interference between the same device radio signals (2〇), the ID identification number (35) can be used to ensure that the radio frequency transmission device (18) radio signal (2〇) can only be associated with a specific radio frequency receiving device ( 19) Connect. As shown in Fig. 5, the transmission interval (30) is about 2 seconds, and the alarm delay (31) is about 10 seconds. The recommended optimal range for the alarm delay (31) is 5 to 15 seconds and has exceeded one-third or three seconds of the transmission interval (30). In order to allow the alarm delay (31) to be adjusted, it is recommended to add a manual delay selection device (32) to the portable base (12) as shown in FIG. The manual delay selection device (32) can be controlled by a single switch for a plurality of alarm delays (31) that do not exceed the transmission interval (30), that is, each time the switch is pressed and can be switched to the next time, The surface space of the portable base (12) can be effectively utilized. It is also suggested in Figure 1 to provide a manual alarm switch (25) on the portable base (12) that operates as described above, but only has two states, open or closed. The manual alarm switch (25) can also be used to activate the receive/alarm control circuit (34), but is preferably used to turn the alarm on/off (16). If it is intended to be used to activate the receive/alarm control circuit (34), it should be set to be the USB connection device (1〇), regardless of whether the signal device (11) is connected, and the portable base (12) is actually Connect, the switch (24) can be turned on to activate the receive/alarm control circuit (34) on the portable base (12). The aforementioned automatic alarm switch (28) can be used to release the alarm (16) when the radio signal (2〇) is received again.
