Low-power standby GPS and Beidou satellite positioning anti-theft system

[0024] Example 1

[0025] see Figure 1 to Figure 4 as well as Figure 7 , a low-power standby GPS & Beidou satellite positioning anti-theft system, including a casing 1 and a casing cover 3, the casing 1 is rectangular, with four sides chamfered, a cavity is provided inside, and the top is hinged with the casing cover 3, which is convenient for relevant personnel. Open the shell cover 3 to repair and replace the internal parts; the shell cover 3 is installed with a locking mechanism, which is used to lock the shell cover 3 to prevent lawbreakers from easily opening it; the shell 1 is installed with a battery 12 and a Beidou locator. 11. The normally closed electromagnetic switch 14, the control module 17, the silent alarm module 19, the wireless transceiver module 18 and the power failure trigger mechanism, the battery 12, the Beidou locator 11 and the power failure trigger mechanism form a communication loop, that is, under normal conditions, The battery 12 only supplies powe

[0030] The difference between this embodiment 2 and the embodiment 1 is that, see Figure 5 to Figure 6 , the top of the shell cover 3 is provided with a first groove 6, the first groove 6 is provided with a second groove 7, the second groove 7 corresponds to the position of the latch 8, and the first groove 6 is also provided with a cover 4 , the rotating shaft 23 extends into the first groove 6, and the end is provided with a hand wheel 5. In order to facilitate subsequent personnel to restore the device to the initial state, by setting the first groove 6 and the second groove 7, after opening the cover 4, press the latch 8 to make it disengage from the slot 21, and rotate the handwheel 5 to drive the rotating shaft 23. The gear 22 is driven to rotate, so that the pin 8 is kept away from the slot 21 of the locking bar 20, and then the device is restored to the initial state, so that the linkage mechanism and the locking mechanism are disengaged from each oth

[0032]The difference between Embodiment 3 and Embodiment 1 lies in that locks are provided on both the shell cover 3 and the cover 4 . The lock is any type of lock in the prior art, which can be an ordinary key lock or a fingerprint lock. The first line of defense is formed by the set lock, and the second line of defense is formed by the set locking mechanism. So that criminals can not easily open the shell cover 3 and cover 4 .
