Description

Technical Field

[0001] The present invention belongs to the technical field of industrial security monitoring, and in particular relates to a low-cost wired monitoring package system and an implementation method thereof. Background Art

[0002] In the field of industrial security monitoring in the existing technology, wired monitoring kits are a mature product solution. Figure 1 As shown in the figure, a general product is a back-end NVR with multiple front-end IPCs. IPC is responsible for image acquisition, encoding and transmission, and NVR receives image data from multiple IPCs through the network and saves it in the hard disk.

[0003] At present, in the system solutions of IPC and NVR, one main control chip is usually equipped with one FLASH chip. After power-on, the main control CPU loads the software from the FLASH chip. After the IPC and NVR are started, they will exchange data through Ethernet to complete related business functions. Figure 2 shown.

[0004] However, in the current monitoring package solution, there are some aspects that need to be further optimized, mainly the following four points:

[0005] 1) Heat generation and stability. In the current IPC solution, reducing power consumption and controlling heat generation are issues that need to be considered urgently. High heat generation will not only lead to overall system instability, but also cause poor image quality.

[0006] 2) Repair. In IPC solutions, FLASH damage is a common damage point. Therefore, among the IPC products that are repaired, a certain proportion is caused by FLASH.

[0007] 3) Hardware complexity. Currently, the PCBs of IPC solutions are relatively small and have a certain degree of hardware design complexity.

[0008] 4) Cost-effectiveness. Improving cost-effectiveness is an eternal topic for products.

[0009] In addition, the commonly used terms in the prior art include:

[0010] NVR: NVR, the full name of Network Video Recorder, is the storage and forwarding part of the network video surveillance system. NVR works with video encoders or network cameras to complete video recording, storage and forwarding functions.

[0011] IPC: IPC is the abbreviation of IP Camera, IP is Internet Protocol, Camera is camera, video camera, IPCamera is a network camera as the name suggests, it is a new generation of camera produced by combining traditional cameras with network technology.

[0012] FLASH: FLASH is a type of memory chip. The data inside can be modified through specific programs. It is often used in embedded systems as a storage medium.

[0013] PCB: PCB (Printed Circuit Board), Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, the support of electronic components, and the carrier for the electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.

[0014] MAC address: A MAC address or media access control address is a hardware identifier that helps you find your device on a local network. Every device connected to the Internet has one. CHIPID: CHIPIO means chip identification number. Each chip has a unique CHIPID that will not be repeated.

[0015] DDR: Double Data Rate refers to double data rate. DDR SDRAM refers to double data rate synchronous dynamic random access memory. Usually, DDR SDRAM is habitually referred to as DDR. Summary of the invention

[0016] In order to solve the above problems, the purpose of this application is to modify the existing wired monitoring package solution, save the FLASH chip, and use the network startup function of the main control CPU to realize startup loading. In this way, the product solution can be optimized in four aspects: heat generation and stability, rework, hardware complexity and cost performance. Including:

[0017] 1) The main control CPU can support network startup function.

[0018] 2) Network boot function, using the CPU's CHIPID to generate a MAC address.

[0019] 3) In the wired monitoring package solution, the FLASH chip of the IPC product is omitted.

[0020] Specifically, the present invention provides a low-cost wired monitoring package system, the system comprising:

[0021] Several (at least 2 or more) network cameras IPC and a network video recorder NVR, the IPC and NVR communicate with each other via Ethernet;

[0022] The NVR includes a main control CPU and a FLASH memory chip; the IPC includes a main control CPU, eliminating the FLASH memory chip in the prior art;

[0023] The firmware resources of the IPC are stored in the FLASH chip of the NVR, and when the NVR firmware resources are produced, the product firmware of the IPC is included;

[0024] The main control CPU of the IPC integrates the network startup function. The network startup function downloads the startup firmware from the NVR when the system starts. That is, after the IPC is powered on, the CPU downloads the startup firmware from the NVR product through Ethernet using the DHCP / TFTP protocol to realize its own system startup and business functions.

[0025] When the system starts, downloading the startup firmware from the NVR further includes:

[0026] When the IPC is powered on, the main control CPU of the IPC obtains the Ethernet IP address from the NVR through the Ethernet using the DHCP protocol. After that, the startup firmware is downloaded from the FLASH of the NVR product to the IPC's own DDR storage through the TFTP protocol. After the download is complete, the IPC starts from the DDR to realize the IPC's own system startup and business functions.

[0027] The network startup includes:

[0028] During the network startup process of the IPC, the Mac address of the data packet is obtained through the CHIP ID of the main control CPU, so that the MAC address is unique and non-conflicting, because the CHIP ID is a unique identification code stored in each chip in the IPC main control CPU.

[0029] The present application also relates to a method for implementing a low-cost wired monitoring package system, which is applied to any of the above-mentioned systems and includes the following steps:

[0030] S1, set the IPC to include only the main control CPU, the IPC firmware resources are stored in the FLASH storage chip of the NVR, and the main control CPU has an integrated network boot function;

[0031] S2, when the IPC is powered on, the IPC's main control CPU applies for an IP address from the NVR's main control CPU via Ethernet using the DHCP protocol;

[0032] S3, after the IPC obtains the IP address, it uses the TFTP protocol to send a request to the CPU of the NVR to download the boot firmware. The firmware is downloaded to the DDR storage of the IPC. After the download is completed, the system is started from the DDR storage.

[0033] Therefore, the advantages of this application are: eliminating the FLASH chip in the existing IPC products, and optimizing the product solution in four aspects: heat generation and stability, rework, hardware complexity and cost performance:

[0034] 1) In terms of heat generation and stability, this method eliminates the FLASH storage chip of the IPC product, which can reduce the system's operating power consumption, reduce heat generation, and improve stability.

[0035] 2) In terms of product repair, the FLASH chip is a point where the product is prone to failure during use. This method eliminates the FLASH storage chip, which naturally reduces product repairs.

[0036] 3) In terms of hardware complexity, the fewer materials used in the hardware design of the product, the higher the integration and the simpler the design. This method saves a FLASH chip material in the hardware, so it can reduce the hardware complexity.

[0037] 4) In terms of cost performance, the hardware material of the product is the direct cost of the product. Eliminating a FLASH chip can reduce the hardware cost of the product and improve the cost performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to more clearly understand the technical content and advantages of the present invention, the present invention is now further described in detail in conjunction with the accompanying drawings.

[0044] The present application embodiment relates to a method for implementing a low-cost wired monitoring package solution, such as Figure 3 As shown, the key point of the technical solution of the present invention is to save the FLASH chip of the IPC product. The firmware resources of the IPC product are stored in the FLASH of the NVR product. The network startup function is integrated into the main control CPU of the IPC. After the IPC is powered on, the CPU downloads the startup firmware from the NVR product through Ethernet and uses a private protocol to realize its own system startup and business functions. During the network startup process, the Mac address of the data packet can be obtained through the CHIPID of the main control CPU, so that the MAC address can be unique and prevent the problem of MAC conflict.

[0045] Specifically, a low-cost wired monitoring kit system is provided, and the system includes:

[0046] A number of network cameras IPCs and a network video recorder NVR. The IPCs communicate with the NVR via Ethernet for data communication. The NVR includes a main control CPU and a FLASH storage chip. The IPC includes a main control CPU, and the FLASH storage chip in the prior art is omitted. The firmware resources of the IPC are stored in the FLASH chip of the NVR, and when making the NVR firmware resources, the product firmware of the IPC is included.

[0047] The main control CPU inside the IPC integrates the function of network startup. The function of network startup is that when the system starts up, the startup firmware is downloaded from the NVR. That is, after the IPC is powered on, the CPU downloads the startup firmware from the NVR product via Ethernet using the DHCP / TFTP protocol to achieve its own system startup and service functions.

[0048] When the system starts up and downloads the startup firmware from the NVR, it further includes:

[0049] After the IPC is powered on, the main control CPU of the IPC obtains the Ethernet IP address from the NVR via Ethernet using the DHCP protocol. Then, the startup firmware is downloaded from the FLASH of the NVR product to the DDR storage of the IPC via the TFTP protocol. After the download is completed, the IPC starts from the DDR to achieve the startup of its own system and service functions.

[0050] The network startup includes:

[0051] During the network startup process of the IPC, the Mac address of the data packet is obtained through the CHIP ID of the main control CPU, and the MAC address can be made unique and non-conflicting because the CHIP ID is the unique identification code that is not repeated for each chip stored in the main control CPU of the IPC.

[0052] This application also provides a method for implementing a low-cost wired monitoring kit system. The method is applied to any of the above systems, as Figure 4 shown, and includes the following steps:

[0053] S1. Set the IPC to only include the main control CPU. The firmware resources of the IPC are stored in the FLASH storage chip of the NVR, and the main control CPU integrates the network startup function internally;

[0054] S2. After the IPC is powered on, the main control CPU of the IPC applies for an IP address from the main control CPU of the NVR via Ethernet using the DHCP protocol;

[0055] S3, after the IPC obtains the IP address, it uses the TFTP protocol to send a request to the CPU of the NVR to download the boot firmware. The firmware is downloaded to the DDR storage of the IPC. After the download is completed, the system is started from the DDR storage.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the embodiments of the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
