The turn-around time of the ultrasonic signal, and the comparison circuit 1〇4 electrically connects the sensing unit driving circuit 102, the ultrasonic sensing receiving circuit and the central control unit 30, respectively, and calculates the body 1 according to the folding time of the ultrasonic signal. The distance between the carriers 40 and the central control unit 3 通知 is notified when the distance between the body 丨 and the carrier 4 开始 begins to change. The ultrasonic sensing unit 101 can be disposed on the bottom surface of the body , so that when the body 1 is placed on a carrier 4 (eg, a table), the ultrasonic sensing unit 101 can face the carrier 4, but The carrier 4 emits a supersonic signal. However, the position defined by the ultrasonic sensing unit 1〇1 is not limited to the bottom surface of the body 1. In another embodiment of the present invention, the complex ultrasonic sensing unit 1G1 may also be tilted. Located on the side of the body 1 week®, the ultrasonic sensing unit 1〇1 can still face the carrier 4〇 by a suitable angle, or a reference object of the surrounding environment of the body i (such as desktop or desktop) The water cup), as such, when the body 1 leaves the carrier 4G, it is bound to increase or decrease the distance from the reference object. __ The alarm module 2G includes an alarm unit 2G1 (alann) and an alarm unit. The driver circuit 202' alarm unit 2〇1 is disposed at a position where the body i can issue an alarm 200921452, such as provided on the bottom surface of the body 1. The bottom surface of the bottom is facing the bee, and the rib is electrically connected by the body 1 202 to invite a single alarm sound and the alarm unit drives the circuit unit 3. The second circuit of the comparison circuit 1〇4: when the “control” can command the alarm unit to drive the circuit to move, so that the bundle secretary drives the alarm early 201. The entry-the second chapter is placed on the carrier 40, And the central control in the post-boot mode, please refer to the figure in the figure, the fourth figure shows the flow chart of the anti-theft method with the device. The body unit 3 is processed in the following manner: (401) Normal use of the operating system; Step (4〇2) to determine whether to log out of the operating system: The main body 1 is often logged out of the operating system in two cases, and the other is the main body] is actively operated by the user and logged out as an operating system. Secondly, the main body 1 is logged out of the operating system in the idle 4 rushing into the protection mode. If the main body 1 is connected, the central control unit 30 performs the step (4〇3). Otherwise, the central control unit 30 Go back to the step (4〇ι); Step (403) to activate the ultrasonic sensor module and the alarm module; the central control unit 3G (4) the above-mentioned ultrasonic sensor module (7) and: 2G and its components 'So, the induction sensor of the ultrasonic sensor module The circuit 1G2 then continuously generates a plurality of ultrasonic signals: and sequentially issued by the ultrasonic sensing unit i〇i, each of the ultrasonic signals is sent to the carrier 4 placed on the body i, and then respectively received. 40 bounces back, the ultrasonic signals after the bounce are sequentially received by the ultrasonic sensing early HM, and the signal receiving _ 1 () 3 receives the ultrasonic signal transmitted by the ultrasonic sensing 200921452 single 101. After processing, the turn-around time of the ultrasonic signal is obtained; step (404) obtains the distance between the body 1 and the carrier 4: the signal receiving circuit 103 transmits the turn-back time of the ultrasonic signal to the ratio = circuit 1G4' comparison circuit 1G4. The turnaround time spent by each ultrasonic signal sequentially calculates the distance that the ultrasonic signal reaches the farthest distance, which is the distance between the body 1 and the carrier 40; Step (405) determines the body! and the placed carrier 4 Whether the distance of 〇 changes: The comparison circuit 1〇4 also compares the distance reached by the latest ultrasonic signal with the distance reached by the previous ultrasonic signal, when the comparison circuit 104 finds the latest supersonic When the distance reached by the signal does not match the distance reached by the upper-speaking ultrasonic signal, the comparison circuit ι〇4 will send a notification signal (such as high or low potential voltage) to the central control unit, and the central control unit 30 will Step (4〇6) is performed, otherwise, the central control unit 30 returns to step (402); step (406) activates the alarm unit 2〇丨 to emit an external alarm: / the central control unit 30 is connected to the comparison circuit 104.
