Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a side sectional view of a low-power consumption intelligent tree nail applied to tree theft prevention according to an embodiment of the present invention, which includes an outer shell and an internal structure. The shell is made of waterproof and anti-extrusion materials, is shaped like a cone, is thick and thin by a little finger and is about 3 cm high. The inner structure includes antenna layer, battery layer and circuit board layer, and the antenna layer includes NB antenna and bluetooth antenna, is located the nail top, and the centre is separated insulating bubble cotton and is reduced mutual interference. The battery layer is arranged in the middle, and 2 CR2450 button batteries are connected in parallel to form a battery pack to supply power to the circuit, so that the stability of voltage is ensured, and sufficient electric quantity is also provided. The circuit board module of the circuit board layer takes a Bluetooth chip with an infinite awakening function as a main control chip and is connected with an NB-IOT module, an eSIM card module, a triaxial sensor module, a radio frequency switch, an external crystal oscillator and an antenna interface module.
Fig. 2 is an electronic structure diagram of a low-power consumption intelligent tree nail applied to tree theft prevention according to an embodiment of the present invention, in which a main control chip employs an ATM2202 having a wireless wake-up function and is externally connected with 16MHZ and 32KHZ crystal oscillators to adjust frequency. The NB-IOT module is connected with the eSim module and used for the NB to position and track the stolen position of the tree. The three-axis acceleration sensor module measures the change of the inclination angle of the tree, the radio frequency switch module can control whether to start communication, and the battery module is connected with the button battery pack for power supply.
This embodiment a be applied to low-power consumption intelligence nail of trees theftproof, install in the tree hole of main branch of tree, the tree hole is repaired to the involution materials involution such as the tree clay that makes with special epoxy, cement and fine sand ratio, repair the surface and scribble the pigment close with the bark, can not be perceived by the thief, mainly use bluetooth communication to carry out the mode configuration, change according to the angle of sensor and displacement change carry out stolen early warning, and utilize NB location technique to track the position of stolen trees.
The intelligent tree nail has 6 working modes, namely a sleep mode, a configuration mode, an installation mode, an anti-theft mode, a stolen mode and a felling mode.
