Without security technology, society will appear unstable, and the progress and development of world science and technology will be affected.

[0004] The popularization and application of Internet of Things technology has made the city's security evolve from a simple security protection system in the past to an integrated urban system. The city's security projects cover many fields, including street communities, buildings, banks and post offices, road monitoring, motor vehicles, police officers, mobile objects, ships, etc. Especially for important places, such as airports, docks, water and electricity plants, bridges and dams, rivers, subways, etc., the introduction of Internet of Things technology can establish a full range of three-dimensional protection through wireless movement, tracking and positioning. It takes into account the overall city management system, environmental monitoring system, traffic management system, emergency command system and other applications.

[0005] The common intelligent security integrated machines on the market, such as face recognition integrated machines, intelligent gate integrated machines, intelligent access control terminals, intelligent NVRs, etc., although fully functional in a certain field, have limited applicability in complex security scenarios. Small and medium-sized scenarios (such as old residential areas, supermarkets, schools, etc.) usually require the use of multiple security devices, such as NVRs (network video recorders), servers, decoders and other devices, which leads to increased network wiring, energy consumption, management, learning and maintenance costs.

[0007] The present invention solves the technical problem by adopting the following technical solutions:

[0030] The present invention is further described in detail below with reference to the accompanying drawings.

[0031] A dual-system intelligent security integrated machine, such as Figure 1 As shown, it includes an X86 system module, an NVR system module, a KVM switching module and a single-chip microcomputer module, wherein the X86 system module is connected to the NVR system module via Ethernet, and the X86 system module and the NVR system module are connected to the HDMI interface, the rear panel and the front panel indicator lights via the KVM switching module, wherein the X86 system module cooperates with the upper-layer software for video surveillance, face application, electronic map, access control management, vehicle management, attendance management, visitor management and patrol management; the NVR system module provides local decoding performance, supports single-screen 100-screen simultaneous video preview for decoding, recording, alarm, audio input and output and port forwarding; the KVM switching module is used for the user's keyboard and mouse control and display switching between the two systems, and a single operation of a certain system will not affect the function of the other system; the single-chip microcomputer module is used to complete the overall power on / off control, reset logic implementation, fan heat dissipation adjustment and system status monitoring.

[0032] The X86 system module includes a VRM multi-phase power supply module, memory, system disk, display output interface and high-speed and low-speed interfaces. The X86 system module uses a 3+2+1+1 phase power supply mode to ensure power supply stability under high load conditions; the DP to HDMI interface in the high-speed and low-speed interfaces provides a display interface for the KVM switching part, and the PCIE high-speed interface in the high-speed and low-speed interfaces is divided into two parts, one part is converted to Ethernet, cooperating with a high-speed Gigabit Ethernet PHY chip, and the other part is used as a host to connect to the NVR system module; the USB part 3.0 interface in the high-speed and low-speed interfaces is used as an external high-speed storage module, and the USB2.0 part in the high-speed and low-speed interfaces is connected to the extender to complete the KVM (virtual display keyboard and mouse control) switching of the X86 system module.

[0033] The NVR system module uses a 3+2+1+1 phase power supply mode and an automatic voltage regulation function, and is equipped with a large-capacity LPDDR4 memory to achieve up to 100 channels of video storage, playback, and forwarding; the NVR system module includes two native output HDMI interfaces, and is equipped with a USB expander to complete the KVM switching of the NVR part; the native SATA port included in the NVR system module is expanded to support up to 8 hard disk storage; the audio part of the NVR system module supports dual-channel microphone input and headphone output, supports 2-channel RS-485 and 1-channel RS-232 communications, as well as local 16-channel level alarm input and 4-channel alarm output.

[0034] The KVM switching module includes an HDMI multiplexer and a USB switch; the HDMI multiplexer uses LT8631, which is enabled through the IIC control on the NVR side. Each channel has separate EDID information and will not conflict. The keyboard and mouse display part of the KVM is implemented through the USB switch, and the expansion is completed through the USB-HUB chip. There are a total of 4 groups of USB2.0 interfaces, which are judged by the GPIO level reserved between the X86 and NVR chips.

[0035] like Figure 2 As shown, the KVM switch module of the present invention is based on USB / IP, is an open source project, has been integrated into the Kernel, and can remotely share USB devices by using USB / IP in a Linux environment.

[0036] Among them, USB Client: Use the USB terminal to mount the USB device shared by the server to the local

[0037] USB Server: Share local USB devices to remote devices.

[0038] The overall switching solution of the KVM switching module based on the USBIP mechanism is: use two groups of GPIO for simple information interaction, control HDMI switching, avoid the use of network protocols, and simplify development; enable two processes separately, control USB switching according to the IO status, and avoid coupling with the business.

[0039] In terms of hardware connection, HDMI switching is controlled by the NVR end, and io is reserved to control USB switching. This time, software is used to share USB without hardware switching. USB is connected to X86 by default. X86 and NVR have two sets of IO direct connections (X86's io1 is connected to NVR's io1, and X86's io2 is connected to NVR's io2). The software can be used at will.

[0040] Two sets of GPIO usage:

[0041] IO1: The HDMI control chip 8361 is controlled at the NVR end. When switching HDMI, the IO1 of the NVR is synchronously controlled to be pulled high or low. The X86 end can know the HDMI status by reading the IO1 status (IO1 high: X86, IO1 low: NVR end).

[0042] IO2: X86 side controls IO2 to pull high or low, and NVR reads IO2 status to control HDMI to switch to NVR side.

[0043] How to switch between X86 and NVR:

[0044] When the X86 screen switches to the NVR, the X86 service calls the driver interface to pull down IO2. After the NVR detects that IO2 is pulled down, it switches HDMI to the NVR (IO1 will be pulled down at this time). When X86 reads that IO1 is pulled down, it knows that it has switched to the NVR, pulls up IO2, and the switch is complete. When the NVR screen switches to X86, the NVR service directly calls the hardware library interface to switch HDMI to X86.

[0045] USB switching method:

[0046] The X86 end starts a process to poll the IO1 status. If the IO1 status is high, all mice and keyboards are unbound and connected to the X86 device. When the IO1 status is low, all mice and keyboards are bound for connection by the USB clint end.

[0047] The NVR starts a process to poll the IO1 status. When the IO1 status is low, it connects all devices shared by the USBIP server. When the IO1 status is high, it executes the USBIP detach process to disconnect all USB devices.

[0048] like Figure 3 The following is a timing diagram of the overall switching process: the X86 platform software is displayed by default when the computer is turned on. The X86-IO driver continuously monitors the status of the two IOs. When the user operates the mouse and keyboard to switch the display interface, the X86 service end issues a call command to notify the switch of HDMI and obtain the status of IO1. The NVR end IO2 generates an interrupt to switch the display to the NVR. The monitoring process of NVR-USB keeps polling USBipserver. As long as there is a shared device, it is connected to complete the switching of the USB device. The process of switching back to the X86 end is the same.

[0049] like Figure 4 The figure shows the matrix driving process: the switching of the video matrix first initializes the LT8631 chip, and IO1 is given a default high level. After the user triggers the call instruction on the business end, the X86 end pulls up IO1, and the NVR end continuously polls the IO2 status. After IO1 and IO2 have confirmed that the levels are correct, the entire switching process is completed.

[0050] like Figure 5 The following is the process flow of USB switching on the NVR side: Since the X86 side and the NVR side have their own independent IP, the ping operation can be used to determine whether the KVM switching can be completed. If the ping is successful, all keyboard and mouse devices are connected. If the ping is unsuccessful or the number of errors continues to increase over a period of time, the device connection status is disconnected. At the same time, IO1 is used to determine whether the usbip thread is working continuously.

[0051] like Figure 6 The figure shows the USB switching process flow on the X86 side: first start monitoring the USB hot plug time process and heartbeat thread to determine whether the switching operation can be performed. If it can be pinged and the bit error does not increase, bind all devices. At the same time, after confirming that the level is correct through IO1 and IO2, the entire switching process is completed.

[0052] like Figure 7 The following is the IO interaction timing diagram: X86-IO driver and NVR-IO driver run at the same time, IO2 of X86 is high by default when it is turned on, HDMI is displayed on X86, upper-layer business software calls the interface, and IO1 and IO2 are used as the basis for selection and monitoring respectively, and IIC of NVR controls LT8631 to switch which channel to select.

[0053] KVM exception handling:

[0054] The NVR chip detects that io2 is continuously pulled down for 500ms before switching. If it is less than 500ms, it is considered to be level interference caused by factors such as static electricity.

[0055] 2. LT8631 displays inconsistent detection processing method:

[0056] HDMI switching is controlled by two LT8631 chips. Normally, they should either be switched to X86 or NVR. The driver starts a thread or timer for timing detection. If inconsistency occurs, it needs to be configured correctly according to the io1 status.

[0057] How to handle abnormal restart of X86 or NVR:

[0058] Abnormal restart of the NVR: The X86 KVM process needs to keep pinging the NVR. If it fails for 10 seconds, it is considered that the NVR is abnormal, and then the usbip unbind operation is performed.

[0059] X86 abnormal restart: The KVM process on the NVR side needs to keep pinging the X86 side. If it fails for 10 seconds, it is considered that the X86 side is abnormal, and then the usbip unbind operation is performed.

[0060] How to handle abnormal process exit:

[0061] Both the X86 and NVR sides need to implement a daemon to ensure that they can restart after an abnormal exit.

[0062] The MCU module is connected to the X86 system module and the NVR system module through the serial port and GPIO respectively to complete the overall power on / off control, reset logic implementation, fan heat dissipation adjustment, system status monitoring and other functions.

[0063] like Figure 8 As shown in the figure, the serial ports of X86 and NVR are connected to the MCU. The power on and off control of NVR is controlled by the MOS tube controlled by the MCU IO. The hard reset part is controlled by the voltage detection chip and the MCU IO. The default restoration part uses the built-in function pins. The MCU is powered by the 5V_SB output of the power supply, and is connected to the PS_ON pin of the ATX to control the power on and off of the whole machine.

[0064] Power on / off function logic:

[0065] Short press to start or normal power-on to automatically start: The MCU directly controls the power-on of all parts. The X86 end is expected to start up in 2 minutes, and the NVR end is expected to start up in 1 minute.

[0066] Long press to shut down: The MCU serial port receives the shutdown request from X86, and the X86 network notifies the NVR to shut down. After all the software is ready, the NVR notifies the MCU to shut down. The X86 controls the VRM rectifier module to power off, and the NVR also executes the software shutdown operation. Finally, the MCU controls the PS_ON pin of the ATX power supply to power off the whole machine.

[0067] Timeout shutdown: If X86 receives a shutdown request and the MCU does not receive a response within 10 seconds, it will shut down and power off automatically. The NVR supports power failure detection, and when it detects that the 12V power fails to below 10V, a reset operation is triggered.

[0068] Hard reset function logic:

[0069] The network heartbeat between X86 and NVR is lost, X86 sends instructions to the MCU to hard reset the NVR through IMP811.

[0070] Hard reset function logic:

[0071] After pressing and holding the restore default button for 3 seconds, the restore default command is sent to the X86 and NVR ends at the same time. The NVR end also supports restoring the defaults separately without affecting the X86 end.

[0072] A working method of a dual-system intelligent security integrated machine comprises the following steps:

[0073] Step 1: During the startup phase, the X86 system module and the NVR system module are started simultaneously.

[0074] After the X86 system module is started in the south bridge, it immediately sends a power-on signal to the VRM power supply module of the memory and CPU, and reads the information in the BIOS to complete the power-on; then the monitoring management platform software in the hard disk is started, and the HDMI output screen.

[0075] Step 2: The X86 system module and the NVR system module conduct network communication negotiation. After the negotiation is successful, the IP proxy process is carried out and the time calibration function is started.

[0076] Step 3: After receiving the heartbeat signal through the serial port, the MCU module continuously monitors the hardware status. If a hardware freeze occurs, it directly controls the hardware to reset the hardware. At the same time, it monitors the temperature and other information, controls the fan for heat dissipation, and completes the system startup.

[0077] Step 4: The user operates the system and switches the display through the KVM switching module, relying on the IIC bus and GPIO pins of the NVR system module to perform the dual-interface switching control function.

[0078] Step 5. The user implements functions such as electronic map, personnel management, vehicle management, access control management, attendance management, visitor management, passenger flow statistics and intelligent patrol through the X86 system module; and implements functions such as video encoding and decoding, video channel management, surveillance recording, face recognition and video analysis through the NVR system module.

[0079] According to the above-mentioned dual-system intelligent security integrated machine and its working method, the effect of the present invention has been verified by building the same system and conducting tests.

[0080] The embodiment is implemented by using the low-power processor of the X86 Celeron platform in combination with a dedicated intelligent security SOC. With the ultra-low power consumption, powerful performance and rich peripheral interfaces of the X86 Celeron platform, combined with the self-developed embedded multi-functional security monitoring software, the performance of the chip is maximized.

[0081] The NVR uses a dedicated smart security chip, which is a new generation of professional high-end SoC chip developed for multi-channel HD / UHD (1080p / 4M / 5M / 4K) smart NVR product applications. The chip integrates the ARM Cortex-A55 octa-core processor and a powerful image analysis tool processor, supports a variety of intelligent algorithm applications, as well as 24-channel 1080p multi-protocol decoding and 4-channel 1080p H.265 / H.264 encoding, and also supports dual HDMI 4K display capabilities and fisheye correction, dynamic contrast enhancement and other image processing functions. Combined with a wealth of peripherals and high-speed interfaces, it can realize a smart security all-in-one machine with low power consumption + large-capacity storage + high network bandwidth + image analysis and recognition algorithm functions in small and medium-sized scenes.

[0082] The system constructed by the present invention is simple: it avoids unnecessary networking configuration, relies on the CPU+NPU design, and both data storage and AI image processing are performed synchronously inside the server-in-one machine, thus avoiding the troubles caused by network congestion.

[0083] The system of the present invention is flexible and efficient: due to the dedicated NVR chip for encoding and decoding, recording, alarm, audio input and output, port forwarding and other functions, it can give full play to the high-performance file processing capability of X86 CPU, analyze the parsed video, carry dedicated platform management software, log in to the web page for management, and have business functions such as video monitoring, face application, electronic map, TV wall, access control management, vehicle management, attendance management, visitor management, patrol management, etc.

[0084] Compared with the prior art, the present invention can reduce costs: compared with the networking configuration of a general storage server + a network hard disk recorder + a multi-channel decoder, it saves costs, can achieve a single unit instead of two units, and saves computer room space.

[0085] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
