Embodiment 1
[0093] Such as figure 1 As shown, this embodiment provides an intelligent anti-theft method. The intelligent anti-theft method comprises the following steps:
[0094] Step S1, the scanning signal transmitter continuously scans a certain area, and the smart anti-theft lock intermittently sends broadcast data packets.
[0095] Outside the door of a supermarket or shopping mall, free areas, alarm areas and restricted areas can be set. The trolley can be pushed arbitrarily in the free area, and the ground in the free area can be painted green; the trolley will give an alarm (sound and / or vibration) in the alarm area. ), the ground in the alarm area can be painted yellow; the trolley will be locked in the restricted area, and the ground in the restricted area can be painted red.
[0096] The scanning signal transmitter adopts a Bluetooth transmitter or a Wifi transmitter; among them, the Bluetooth transmitter covers an effective area of about 20 meters, and the Wifi transmitter...
Embodiment 2
[0114] Such as figure 2 As shown, this embodiment provides an intelligent anti-theft lock. The intelligent anti-theft lock includes a lock 1, a driver 2, a controller 3 and a scanning signal transmitter 4. The driver 2 drives the corresponding lock 1 to lock or unlock, and the controller 3 is used to control the action of the corresponding driver 2. The scanning signal transmitter 4 adopts but is not limited to a Bluetooth transmitter or a Wifi transmitter. The driver 2 adopts but is not limited to a servo motor. It should be noted that the scan signal transmitter 4 can send instructions to multiple controllers 3 at the same time.
[0115] Such as image 3 As shown, each controller includes a drive control circuit 31 , an alarm circuit 32 , a communication circuit 33 and a processor 34 , and the drive control circuit 31 , alarm circuit 32 and communication circuit 33 are electrically connected to the processor 34 . in,
[0116] The processor 34 is configured to intermitt...
Embodiment 3
[0173] Such as Figure 9 As shown, the WIFI circuit of the processor and communication circuit provided by this embodiment includes a first chip U1, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a first capacitor C1, the second capacitor C2 and the first diode D1; wherein,
[0174] The first chip U1 is a chip with a model number of MT7681.
[0175] The first end of the first resistor R1 is grounded, and the second end of the first resistor R1 is electrically connected to the first end of the second resistor R2 and the first end of the third resistor R3;
[0176] The second end of the second resistor R2 is electrically connected to the power supply;
[0177] The second end of the third resistor R3 is electrically connected to the twentieth pin of the chip and the first end of the first diode D1;
[0178] The first end of the fourth resistor R4 is electrically connected to the fifteenth pin of the chip, and the seco...
