[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 2 As shown, this utility model provides a remote local cable anti-theft alarm device, including a housing 1. Four electrical conduits 2 are connected inside the housing 1. The other end of the first electrical conduit 2 is connected to a foot switch 4. A cable storage frame 6 is placed on the top of the foot switch 4 to store cables 5. Cables 5 are placed inside the cable storage frame 6. A human body induction switch 7 is fixedly installed at the other end of the third electrical conduit 2. The human body induction switch 7 is positioned vertically above the cables 5 to detect passing people.

[0019] Specifically, a diffuse reflection photoelectric switch 3 is fixedly installed at the other end of the second conduit 2, and the diffuse reflection photoelectric switch 3 is close to the outside of the cable storage frame 6. The diffuse reflection photoelectric switch 3 is linked with the cable, and when the cable leaves its monitoring range, it immediately responds and issues an alarm message.

[0020] Furthermore, a remote alarm receiver 8 is installed at the other end of the fourth conduit 2, and the remote alarm receiver 8 is placed inside the electrical box, which is placed on the ground. The remote alarm receiver 8 is used to receive signals.

[0021] Furthermore, the human body sensor switch 7 has red positive and black negative input wires, and red positive and white negative output wires.

[0022] It is worth noting that the voltage and current of the diffuse reflection photoelectric switch 3 are 6-24V, and it has brown positive, blue negative and black outputs.

[0023] It is worth noting that the dimensions of foot switch 4 are 1000*400*2mm.

[0024] Working principle: The device will immediately sound an alarm when the following conditions are met.

[0025] 1. When a person approaches within 1m of cable 5 and the power supply to cable 5 is cut off, the human body induction switch 7 and the power failure protection device will immediately respond and issue an alarm signal (simultaneously remotely and locally).

[0026] 2. When a person moves cable 5 to a certain distance (the distance can be set according to the requirements), the diffuse reflection switch 3 will immediately respond and send an alarm signal (both remote and local).

[0027] 3. When a person moves the cable 5 to a certain distance (the distance can be set according to the requirements), the foot switch 4 will immediately respond and send an alarm signal (both remote and local).

[0028] The device consists of: a housing, a power supply, a detection device, and an alarm device.

[0029] 1. Outer casing 1: i.e. electrical box, where the required electrical components are fixedly arranged and combined according to the required positions.

[0030] 2. Power supply: It consists of mains power, backup power (lithium battery), AC voltage regulator circuit, automatic switching circuit between mains power and backup power, and lithium battery charger (considering that backup power will be used to provide power after the mains power fails, to ensure the normal operation of the alarm). The switching power supply is a stable power supply with a power of 50W and a DC voltage of 12V.

[0031] 3. Detection Device: Composed of an all-weather human body induction switch 7, a diffuse reflection photoelectric switch 3, and a foot switch 4. Human body induction switch 7: Due to its wide sensitivity range, a circular black cylinder with an inner diameter of 30-50mm and a length of 50mm is placed on the induction probe to adjust the sensing range. Diffuse reflection photoelectric switch 3 is linked to the cable; when the cable leaves its monitoring range, it immediately responds and issues an alarm.

[0032] 4. Foot switch 4: Placed below the cable, it will immediately respond and issue an alarm message if there is insufficient weight above or if the object is moved.

[0033] Installation of alarm devices

[0034] The outer casing 1, human body induction switch 7, diffuse reflection photoelectric switch 3, and foot switch 4 are installed in concealed locations, making them difficult to detect. The remote alarm device is a modified remote control. The transmitter is installed inside the outer casing 1, and the receiver is installed at the alarm prompt location (such as an office area or security room). Due to signal transmission issues between the transmitter and receiver, the size of the remote control can be selected according to the environment.
