technical field

This application relates to the field of network device control. In particular, a plug-and-play method of device activation.

Background technique

There are two main types of plug-and-play solutions for traditional video surveillance equipment:

First, NVC devices can automatically discover NVT devices through protocols such as onvif, and then send requests to NVT devices through onvif protocols. In this solution, NVT devices do not require authentication or only use default passwords, so non-related personnel can easily log in And access the device, leaving security risks.

A plug-and-play device activation method provided by the present invention is applied between NVC devices and NVT devices. Here, NVT (full English name: NetworkVideoTransmitter) device refers to the network video transmission end, which is used to send video data to the client through the IP network. For example: webcam or encoding device. NVC (English full name: NetworkVideoClient) device refers to a network video client, which is used to receive video streams and control NVT devices. For example: network hard disk video recorder or video management server, etc. In this embodiment, a network video recorder and a network camera that interact based on the onvif protocol are taken as an example for illustration. It should be noted that the NVC device is not limited to the network video recorder, and the NVT is not limited to the network camera. The protocol is not limited to the onvif protocol either.

In conjunction with Fig. 1, it is specifically described that the present invention realizes embodiment one flow process as follows, at first when setting in the initial state, the network hard disk video recorder and the network camera are all in the limited working mode, and the network hard disk video recorder starts its own onvif equipment management module to search the network camera, and utilizes The security activation code obtained by itself sets the first activation code of the found network camera, activates the associated network camera, and makes the network camera in the normal working mode; after the network camera works normally, the network hard disk video recorder initiates a video service request to the network camera , the network camera sends back the video code stream to the network hard disk video recorder device.

It should be noted that when the network camera is in the limited working mode, its device management module for responding to the search and discovery of the network hard disk video recorder can work normally, so that the network hard disk video recorder can search and find the network camera. Its remote accessed module and business response module do not start. In the normal working mode of the network camera, in addition to the normal working of the aforementioned equipment management module, its remote accessed module and business response module can work normally. When the network hard disk video recorder is in the restricted working mode, its device management module and service request module used to search for network cameras are available; The business response modules all work normally.

In addition, although the step of the NVC device searching and discovering the NVT device through the device management module is located before the step of obtaining the security activation code in the first embodiment, it can also be located after the step. The sequence of steps in Figure 1 is only used as an implementation example.

It can be seen from this embodiment that in a networking environment, no matter whether the NVC device is in a normal or restricted working state, the NVT device can be activated and work normally, and the operation is simple and convenient. Before the NVT device is activated, its remote accessed module and business response module will not start, and the whole process can protect the security of the NVT device data to the greatest extent. After the NVC device uses its security activation code to automatically activate the NVT device, the NVT device sends video data to the NVC device, and on the basis of ensuring data security, the plug-and-play of the device is realized.

The following further explains how the NVC device obtains the security activation code to activate the NVT device. In this embodiment, a network hard disk video recorder and a network camera are still taken as examples for illustration.

(1) Obtained through the local man-machine interface of the network hard disk video recorder. What needs to be explained here is that the security activation code obtained through the local man-machine interface can be manually input by the user on the running wizard of the local man-machine interface. In this case, the security activation code is self-defined or preset; It can be a random password obtained by the device itself through a key algorithm. In this case, the generated random password will be displayed on the running wizard of the local HMI, and the user clicks OK, that is, the user defaults to the random password as a security activation code to activate the device.

In the above two methods, in the former method, the user can activate his own device and the related network camera device only by entering a password once, and the operation is simpler and more convenient than the prior art. In addition, the security activation code is set by the user, so it is easier to remember and has high stability and security. However, considering that in the case of some large-scale monitoring networks, such as the security deployment and control system of Ping An City, which contains multiple small-scale networks and most of them are cross-regional settings, if the local HMI is used to obtain the security activation code, the user It is still necessary to go to the equipment site, which is a waste of time and manpower, so there are still many inconveniences. In the latter method, the random password is generated by the device itself, and the random password is obtained through the key algorithm inside the device. Therefore, only the network hard disk video recorder itself and the relevant network camera know the password, and the security is high. However, under normal circumstances, randomly generated passwords are relatively complicated and inconvenient to remember.

Based on the above problems, the present invention also proposes (2) obtaining the security activation code through the input of the mobile phone bound with the device. In this case, it is required that the mobile phone registration module can work normally in the limited working mode of the network hard disk video recorder.

Specifically, the mobile phone registration module of the network hard disk video recorder initiates registration to the remote server with its own identity when registering, and the mobile phone logs in to the remote server. After login, the mobile phone scans the QR code of the network hard disk video When the two-dimensional code information of the mobile phone is consistent with the logo stored on the remote server, the network hard disk video recorder is bound to the mobile phone; after the mobile phone is bound, the user manually enters a custom or pre-defined password through the mobile phone interface as a security activation code. The method of activating the relevant network camera through the network hard disk video recorder is the same as the above-mentioned solution, and will not be repeated here. In this way, the operation is convenient, the safety is high, and the stability is also high.

The two methods of obtaining the security activation code mentioned here are only exemplary embodiments of the present invention, but are not limited to these two methods. Other methods of obtaining the security activation code that exist in the prior art or have the same effect are all included within the scope of the present invention.

It can be seen from Embodiment 1 of the present invention that no matter whether the NVC device is in the normal working mode, the associated network camera can be activated and in the normal working state, realizing the plug-and-play function of the device, which is convenient to operate and has high security.

However, it should be noted that when the NVT device is in the normal working mode and the NVC device is in the restricted working mode, the remote accessed module of the NVC device and some signaling ports and service sending ports are restricted and cannot work normally, so it is more applicable It is suitable for small-scale networking and within the range of the same LAN.

Therefore, the present invention further provides the second embodiment, referring to FIG. 2 , about how to make the NVC device also work in the normal working mode. Still taking the network hard disk video recorder and network camera as examples, specifically, the main difference from the first embodiment is that after the network hard disk video recorder in the first embodiment obtains the security activation code, it uses the security activation code as its own second activation code. code to activate its own device and put itself in normal working mode. When the network is in the normal working mode, the network hard disk video recorder and the associated network camera can perform normal signaling and video service interaction, and receive the management of the upper layer server when the network hard disk video recorder is in the normal working mode, such as the management of VM equipment . Here VM (English name: VideoManager) device is a video management device. Usually a management server. The status of the VM device in this embodiment is actually an upper management device that manages the NVC device. It can be seen from the second embodiment that after the NVC device is in the normal mode, it can perform normal signaling and video service interaction with the NVT device, and is managed by the upper management device, which is applicable to large-scale networking systems.

In the step of FIG. 2 , the NVC device searches and finds that the NVT device is located before obtaining the security activation code, which is only used as an example of an implementation of Embodiment 2 and does not play a limiting role. Similarly, the NVC device activates its own device by setting the security activation code as the second activation code, although it is located before activating the NVT device in FIG. 2 , which is only an exemplary step and not a limitation. Of course it can also be synchronized with the activation of the NVT device or after the activation of the NVT device.

The invention obtains a security activation code to activate the NVC device and activates the discovered NVT device through the NVC device, and realizes the plug-and-play function of the device in the networking system, which not only has high safety, but also is convenient to operate.

Corresponding to the foregoing embodiment of the method for activating a plug-and-play device, the present application also provides an embodiment of a system for activating a plug-and-play device.

In conjunction with FIG. 3, a plug-and-play device activation system of the present invention is further described, including NVC devices and NVT devices.

Preferably, in the limited working mode, the normal working module of the NVC device includes not only the device management module for searching for NVT devices, but also a mobile phone registration module for initiating registration to the remote server, the The normal working module of the NVT device includes a device management module for responding to search information when the NVC device searches for the NVT device.

Preferably, the NVC device includes a local man-machine interface for obtaining the security activation code. It also includes binding the NVC device to a mobile phone for obtaining a security activation code when the NVC device is in a restricted working mode;
