Description

Technical Field

[0001] The utility model belongs to the technical field of metal detection, and in particular relates to a large-scale distributed metal detection network. Background Art

[0002] Metal detectors usually include a transmitting metal detection coil (used to generate an electromagnetic field), a receiving metal detection coil (receiving the metal object's response to the electromagnetic field), a control unit and a display screen (controlling the generation and reception of the electromagnetic field, processing the received signal, and outputting it to the display screen). Alternating current generates a rapidly changing magnetic field through the transmitting metal detection coil, which induces eddy currents inside the metal object. The magnetic field generated by the eddy current affects the original magnetic field, causing the metal detector to send a signal. The detection depth of traditional metal detectors is usually between a few centimeters and tens of centimeters, which is suitable for metal detection in a small range or shallow layers. The detection range is relatively limited, especially for large areas or irregular areas. The detection efficiency is low. The accuracy of its detection is also limited by the performance of the detector and environmental factors. Traditional metal detectors are easily affected by external electromagnetic interference, especially in areas with complex electromagnetic environments, which may cause false alarms or missed alarms. Traditional metal detectors can usually only provide simple detection results, with limited data processing and storage capabilities, and it is difficult to process and analyze large amounts of data. And they need to be installed and debugged one by one, and expansion and maintenance are cumbersome. Its flexibility is also relatively low, and it is difficult to adapt to complex and changing environmental requirements. Utility Model Content

[0003] The utility model aims to provide a large-scale distributed metal detection network to solve the above-mentioned technical problems.

[0004] To achieve the above purpose, the specific technical solution of a large-scale distributed metal detection network of the utility model is as follows:

[0005] A large-scale distributed metal detection network includes a rope network, a small metal detection device and a metal detection coil. The rope network forms a criss-cross mesh structure. A small metal detection device is installed at each intersection. Metal detection coils are arranged within the range of each group of four adjacent intersections of the rope network. The metal detection coils form a square closed loop, and the beginning and end are connected to the small metal detection device. Each metal detection coil is independent of each other.

[0006] Furthermore, the small metal detection device includes a plastic round shell, a micro PCB circuit board, a small button battery, an LED indicator light and a vibration sensing element. The micro PCB circuit board, the small button battery, the LED indicator light and the vibration sensing element are all arranged in the plastic round shell. The small button battery, the LED indicator light and the vibration sensing element are electrically connected to the micro PCB circuit board. The small button battery is used to power the device, the LED indicator light is used to display the detection results, and the vibration sensing element is used to send a vibration signal; the micro PCB circuit board is the device processing center.

[0007] Furthermore, the plastic round shell is the size of a coke bottle cap and is placed on each intersection of the rope net.

[0008] Furthermore, the diameter of the micro PCB circuit board is about 3-4 cm.

[0009] Furthermore, the micro PCB circuit board includes a CPU circuit, a metal detection circuit, a signal sampling circuit, a buzzer circuit, an independent key circuit, a program download circuit, and a USB to serial port download circuit. The metal detection circuit is connected to the signal sampling circuit, the signal sampling circuit is connected to the CPU circuit, the buzzer circuit, the independent key circuit, the program download circuit, and the USB to serial port download circuit are connected to the CPU circuit, the metal detection circuit is connected to an external metal detection coil to receive the induction signal of the metal detection coil; the signal sampling circuit is used to collect the signal of the metal detection circuit and convert it; the buzzer circuit is used to emit a sound signal; the independent key circuit is used for resetting; the program download circuit is used to provide program download; and the USB to serial port download circuit is used to provide interface conversion.

[0010] Furthermore, the metal detection coil is externally connected to a micro PCB circuit board to generate and receive electromagnetic signals.

[0011] Furthermore, the brightness of the LED indicator light changes according to the strength of the metal detection signal.

[0012] Furthermore, when the vibration sensing element is vibrated, the vibration sensing element will trigger the small metal detection device to turn on; when there is no vibration sensing, the device enters a standby state.

[0013] The utility model of a large-scale distributed metal detection network has the following advantages:

[0014] Improve detection range and accuracy: By placing metal detection devices at each node of the network, the distributed metal detection network can cover a wider area and achieve all-round and multi-angle detection of metal objects. This layout can significantly improve the accuracy and reliability of detection and reduce the possibility of missed detection and false alarms. It has a wide range of applications and can be used in many fields such as metal mineral exploration, safety inspection, and scrap metal recycling.

[0015] Enhanced system flexibility: The design of the distributed metal detection network allows the location and number of detection nodes to be flexibly adjusted according to specific needs. This means that in different scenarios or environments, detection nodes can be increased or decreased as needed to meet different detection requirements. This flexibility enables the distributed metal detection network to better adapt to various complex application scenarios.

[0016] Improve system reliability and stability: Since the metal detection chip is distributed on multiple nodes, even if a node fails or is disturbed, other nodes can still continue to work. This distributed design improves the reliability and stability of the system and reduces the impact of single point failure on the entire system.

[0017] Reduced use and maintenance costs: The maintenance cost of the distributed metal detection network is relatively low. Since the detection nodes can work independently, it is only necessary to regularly check and maintain each node. It is highly intelligent and can automatically turn on and off, reducing energy consumption and extending service life. BRIEF DESCRIPTION OF THE DRAWINGS

The rope net 1 forms a criss-cross mesh structure, a small metal detection device 2 is installed at each intersection, and the metal detection coil 3 is arranged within the range of each group of four adjacent intersections of the rope net. The metal detection coil 3 forms a square closed loop, and the beginning and end are connected to the small metal detection device 2, and each metal detection coil 3 is independent of each other.

[0023] like Figure 2 As shown, the small metal detection device 2 includes a plastic round shell, a micro PCB circuit board, a small button battery, an LED indicator light, and a vibration sensing element. The micro PCB circuit board, the small button battery, the LED indicator light, and the vibration sensing element are all arranged in the plastic round shell. The small button battery, the LED indicator light, and the vibration sensing element are electrically connected to the micro PCB circuit board. The small button battery is used to power the device, the LED indicator light is used to display the detection result, and the vibration sensing element is used to send a vibration signal; the micro PCB circuit board is the device processing center. Through the triggering of the vibration sensing element and the display of the LED indicator light, the presence and strength of the metal substance can be easily judged. At the same time, the device also has a standby mode to reduce energy consumption.

[0024] The plastic round shell is about the size of a coke bottle cap and is placed at each intersection of the rope net 1. The entire small metal detection device 2 has the characteristics of small size, low power consumption, and easy installation and maintenance.

[0025] Micro PCB circuit board: The diameter is about 3-4cm, which is the core part of the device.
