[0024] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.

[0025] Example. An electronic fence system with enhanced protection capability, such as Figure 1 、 10 As shown in Figure 11, the system is based on a core chip and integrates multiple functional modules. The core chip is Kanzhi K210; the functional modules include a visual perception module, an auditory perception module, a network access module, a warning-alarm module and a communication module.

[0026] The Kanzhi K210 chip adopts the RISC-V processor architecture and has three major features: integrated audio and video, independent IP core and strong programmability. It supports multimodal recognition of machine vision and machine hearing, and is widely used in scenarios such as smart homes, smart parks, smart energy consumption and smart agriculture.

[0027] The visual perception module is connected to the external finished product GC0328 dual camera module (2 million pixels) through the onboard FPC connector (25P, P = 0.3mm). The principle is as shown in the attached figure. Figure 2 , through the DVI communication port of the K210 chip to achieve communication and complete the collection of video image data;

[0028] After the chip collects video image data, it will automatically perform real-time calculations to realize the functions of operator face recognition and distance measurement. The recognition result will serve as one of the bases for whether the system will activate the alarm system.

[0029] At the same time, in order to ensure the reliability and accuracy of recognition, the Anxinke Rd-03D millimeter wave radar module (24GHz, the maximum sensing distance can reach 8m) is additionally used on the basis of the visual solution. The principle is as follows Figure 3 By communicating with the K210 chip through the UART serial port, it can sense in real time whether there are multiple moving or slightly moving human bodies in the area, and obtain the real-time distance to the target. The recognition result is also one of the bases for the system to activate the alarm system, but its priority is higher than the pure visual distance measurement solution to ensure the stability and reliability of the system in different environments.

[0030] The auditory perception module is connected to the external digital microphone array module through the onboard FPC connector (8P, P=0.3mm) and communicates with K210 through the I2S protocol;

[0031] Principle Figure 4The digital microphone array module is composed of 6 digital microphones (MSM261S4030H0R) to form a microphone array, which can locate the sound source within a 360° range with a 60° recognition interval; the digital microphone at the center of the module is used for natural language recognition, on-site environmental sound perception and on-site sound recording.

[0032] The network access module includes access to the Internet (or internal LAN) through an RJ45 network port and an external WiFi module, and interacts with other network devices on the network;

[0033] The wired Ethernet connection used by the RJ45 network port uses the W5500 chip and the K210 SPI bus to achieve two-way communication. The principle is as follows Figure 5 The video image data can be processed in real time and transmitted to the network in the form of RTMP video streaming protocol. Other network devices can interact with the system in real time through Socket or WebSocket protocol connection, view corresponding alarm information records, personnel operation records and other log information, and can also modify some non-sensitive settings of the system.

[0034] The same function can be achieved through the WiFi wireless data transmission module. The UART serial port of K210 is connected to the W600 WiFi module through a 2.54mm female header. The principle is as follows Figure 6 , so that the device can access the network;

[0035] Due to the use of the universal RTMP video streaming protocol, this system can be used as a real-time camera in video security monitoring and can be directly connected to most monitoring systems on the market to display real-time video images on site;

[0036] At the same time, the images from other cameras in the existing monitoring system can also be connected to the system in the reverse direction through the RTMP video streaming protocol, acting as additional video acquisition devices (cameras); as more cameras are connected to the system, the system's early warning range and effect are improved, enabling active protection in multiple angles, dimensions, and regions.

[0037] The warning-alarm module includes a relay, a laser projection lamp, an alarm and an LED strobe warning light; the relay controls the switch of the 220V laser projection lamp, the high-decibel alarm and the LED strobe warning light. Figure 7 ;

[0038] After activation, the laser projection light will display a safety warning area and safety warning text on the ground. If someone mistakenly enters the warning area or an unauthorized person attempts to operate, the laser projection light will flash intermittently and an audible and visual alarm will be activated simultaneously. The background will record the current illegal intrusion information as a basis for subsequent investigation and analysis.

[0039] The built-in speaker is controlled via the K210's I2S bus. The onboard MAX98357A converts the I2S bus signal into the analog audio signal required by the speaker, enabling it to cooperate with the auditory perception system to enable the system to act as a vote-caller to operate the vote counting or implement remote shouting functions through the monitoring system, as well as broadcast more alarm content.

[0040] This application supports RS485 and RS232 communication protocols commonly used in industrial systems, and is connected to the UART serial port of K210 through the onboard MAX3160 chip (RS-232 / RS-485 / RS-422 multi-protocol transceiver). The principle is as follows Figure 8 , the system can realize 2TX / 2RX RS-232 communication mode through pin programming, and also enable the system to be used as a single RS-485 / 422 transceiver; thus, the system can be connected to most existing industrial process control, intelligent security / arming systems on the market, and provide more comprehensive sensing capabilities for the above systems as an external sensor; and realize active protection on the upper level process control. If it is found that someone accidentally enters the work danger zone, the production line will automatically stop to protect the safety of personnel;

[0041] The system's own CAN bus is implemented through the SN65HVD230 chip. The principle is as follows Figure 9 , which can realize cascading between multiple identical devices, so that each device can realize computing power sharing, camera video picture sharing, video surveillance area combination, system configuration synchronization and other functions that facilitate later maintenance and improve user experience

[0042] An external light strip is also provided; the external light strip is associated with the electronic operation ticket to realize the path planning and guidance function for on-site personnel, guiding personnel to the corresponding area for operation.
