[0002] Street lamps are an important part of urban infrastructure. They can not only provide lighting for public areas of roads, but also enhance the beauty of the city through the design of lights. Therefore, they are widely used in public areas such as roads, squares, and parks.

[0003] Existing street lamps are mostly installed outdoors in open spaces when in use, and the poles and lamp shades of street lamps are usually made of aluminum alloy or stainless steel. These metal materials have a high recycling value in the market, and existing street lamps usually do not have any anti-theft mechanisms. Therefore, these street lamps are very prone to theft.

At this time, a high-frequency signal input will be triggered, and the level of pin 12 of the U2 chip will change from the original high level to a low level, triggering pin 13 of U2 to output a corresponding signal to the alarm to control it to emit an alarm sound. After the trigger, all functions of the controller will be turned off, and the alarm will still continuously output the alarm sound. After the trigger, even if the switch of the controller is turned off (KJ is connected to pin 14 of U2 and forms a switch circuit with GND), the alarm will still continuously output the alarm sound, which can effectively prevent theft. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a schematic diagram of the circuit structure of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] In Figure 1Among them, an anti-theft device includes: an anti-theft device housing, an energy storage power supply, and a buzzer, and is characterized in that:

[0021] There is a circuit system inside the anti-theft device that will alarm when the angle is tilted;

[0022] The circuit system includes: a power module, an infrared receiving circuit, a charging part, an LED load output control, a power indicator module, a key, and an anti-theft control interface.

[0023] Power module

[0024] BAT+ and BAT- are the main battery power inputs: filtered by a large-capacity electrolytic capacitor EC1 to remove most of the ripple in the power supply and provide stable DC power for the entire circuit. Power the single-chip microcomputer: through a parallel voltage regulator circuit composed of R19, C1, C6, and ZD1 to prevent the power supply voltage of U2 from exceeding 5.1V and provide a stable operating voltage for U2 and some key circuits.

[0025] Infrared receiving circuit

[0026] The VCC of the infrared receiving head (IR) is connected to the R17 (470R) pin to the power supply, the GND pin is grounded, and the OUT pin is connected to the R18 (470R) to the 2nd pin of the chip U2. In the anti-theft system, it can be used to receive commands such as arming and disarming sent by the user through the infrared remote control, and can also receive commands for the controller.

[0027] Charging part

[0028] Charging protection circuit: composed of resistors and transistors such as Q1-Q6, R9, R10, R11, R13, and Q9 to form a charging protection circuit. SP+ and SP- are externally connected to the photovoltaic panel, and the voltage is divided by R12 and R13 to U2. When U2 detects that the charging voltage is higher than the internally set voltage, the 7th pin outputs a high level to turn on the charging function, and at the same time the 5th pin outputs a low level to turn off the LED load. The battery voltage detection is divided by R6, R7, and C2 to the 10th pin of U2. When the 10th pin of U2 detects that the battery voltage is greater than the fully charged battery voltage, the 7th pin outputs a low level to turn off Q1 to Q6 to stop the battery and achieve the full charge protection function.

[0029] The LED load output control is composed of R14, R15, Q7, and Q8, and the 5th pin of U2 outputs a duty cycle to drive Q7 and Q8 to adjust the brightness of the LED load.

[0030] Power indicator module

[0031] Pins 11, 14, and 15 of chip U2 are connected to resistors R1, R2, and R3, and output corresponding levels to drive the R (red), B (blue), and G (green) light-emitting diodes to display different charging states. When the red LED is on, it indicates that charging is in progress. When the green LED is on, it indicates that the battery is fully charged. The B (blue) LED is reserved and has no function for now.

[0032] Among the said buttons, KJ is connected to pin 14 of U2 and forms a switch circuit with GND, which is used to manually turn on or off all functions of the controller except the alarm.

[0033] Anti-theft control interface

[0034] PC control socket: Connects the induction device and the alarm. When the sensor detects an abnormality and there is a short circuit (once or multiple times) between pin 12 and pin 16 of U2 chip. (For example, when the solar lamp is moved by someone, 1. when the angle is greater than 100 degrees, the alarm is triggered; 2. various sensors such as switches, infrared, sound control, and light control can be equipped). A signal will be output and transmitted to pin 12 of U2. After being confirmed by the U2 program, pin 13 will output a corresponding signal to trigger the anti-theft alarm.

[0035] The anti-theft street lamp includes a lamp post and a lamp housing; the anti-theft device is arranged in the lamp housing.

[0036] Explanation of the circuit connection diagram of the induction device and the alarm

[0037] 1. Pins 12, 13, VCC, and GND of microcontroller U2 form the external sensor and alarm circuit, and the induction part is composed of R4 and GND;

[0038] For the induction device, when it detects that the solar lamp has an event (such as when the solar lamp is moved by someone, 1. when the angle is greater than 100 degrees, the alarm is triggered. 2. various sensors such as switches, infrared, sound control, and light control can be equipped) and is connected to pin 12 and GND (once or multiple times), a short circuit will occur, and a high-frequency signal input will be triggered. The level of pin 12 of U2 chip will change from the original high level to a low level, triggering pin 13 of U2 to output a corresponding signal to the alarm to control it to emit an alarm sound. After the trigger, all functions of the controller will be turned off, and the alarm will still continuously output the alarm sound. Even if the switch of the controller (KJ is connected to pin 14 of U2 and forms a switch circuit with GND) is turned off after the trigger, the alarm will still continuously output the alarm sound, which can effectively prevent theft.

[0039] The above anti-theft device can be used for solar street lamps, floodlights, and important electrical equipment. When the angle changes, an alarm signal can be issued to effectively prevent theft.
