Description

Wireless video monitoring system and video monitoring method thereof

technical field

The present invention relates to the technical field of video monitoring, in particular to a wireless video monitoring system, a video monitoring method of the wireless video monitoring system, a video monitor and a server for wireless video monitoring. the

Background technique

Video surveillance is an important part of the security system, and it is a comprehensive system with strong prevention capabilities. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, video surveillance technology has also made great progress. Since 2004, with the improvement of network bandwidth and cost reduction, the increase of hard disk capacity and the reduction of central storage costs, and the emergence of various practical video processing technologies, video surveillance has entered a fully digital network era. the

With the continuous development of video surveillance technology, its application is becoming more and more extensive, and users' requirements for video surveillance are getting higher and higher. At present, more and more users hope to use video surveillance system to realize remote monitoring, so as to understand in real time Conditions of the monitored place. the

Existing video monitoring systems are generally implemented using a C/S (client/server) structure, and are usually provided with: a monitoring front end (video capture device, such as a video camera, camera, etc.), a monitoring center server (usually a streaming media server) and a monitoring terminal (client). By placing one or more monitoring front-ends in the monitoring place to collect video images on site, and then transmit the video signal to the designated monitoring center server through a certain transmission network, such as cable, optical fiber or Ethernet, and then transmit the video data The video data is stored in the storage device of the server, and the video data is sent to the monitoring terminal by the server. the

First of all, this method of uniformly storing video data on the server side will lead to a large number of video data read and write operations in practical applications. Due to the complexity of video data processing, a large number of read and write operations will inevitably cause data errors and loss. Occurs frequently, which makes the existing video surveillance system have great data security risks. the

Furthermore, in the existing video surveillance system, most of the monitoring front-end and the monitoring terminal have a one-to-one relationship, that is, one monitoring front-end can only be used to be viewed by one monitoring terminal, so the number of monitoring front-ends and monitoring terminals is quite large. of. If there are many users, the load of the monitoring center server to process video signals will be too large. Moreover, since the video surveillance system is aimed at the processing of video data, involving a series of operations such as algorithm call, compression, transmission, and large-capacity storage, the requirements for the performance of the server itself are very high, which will become a bottleneck for improving efficiency. However, if the one-to-one configuration of the monitoring front-end and the monitoring terminal is not adopted, and the communication interface between one monitoring front-end and multiple monitoring terminals is opened, although the load on some servers can be relatively reduced, there will be a greater security risk. the

In short, a technical problem that needs to be urgently solved by those skilled in the art is: how to propose a wireless video surveillance solution to improve data security, reduce server requirements, reduce server load, and effectively improve system and communication. security. the

Specifically, the authentication server of the present invention can be connected with the video monitor and the monitoring terminal through the wireless Internet, and the video monitor and the monitoring terminal authenticated by the authentication server can communicate point-to-point through the wireless communication network. the

Of course, it is easy for those skilled in the art to think that the authentication server of the present invention can also be connected to the video monitor and monitoring terminal through the wired Internet, and the video monitor and monitoring terminal authenticated by the authentication server can also be connected through wired communication The network communicates point-to-point. The video monitoring system of the present invention is preferably implemented based on a wireless communication network, such as a 2G network, a 3G network, etc. Therefore, in the embodiments of the present invention, the wireless communication network is used for illustration. the

To apply the present invention, it is first necessary to associate the video monitor with the monitoring terminal, so as to ensure the connection and communication between the two in the subsequent process. The association operation is mainly realized by the association module of the video monitor. In a preferred embodiment of the present invention, the association module may include the following submodules:

The code pairing sub-module is used to trigger the code pairing mode, and receive the code pairing operation initiated by the monitoring terminal in the code pairing mode;

The information acquisition sub-module is used to establish the association relationship between the current video monitor and the code monitoring terminal when the code matching operation is successful;

The registration submission sub-module is used to send the network address information of the current video monitor, and the identification information of the current video monitor and the identification information of the associated monitoring terminal to the authentication server. the

The above-mentioned code pairing operation is a commonly used method for associating different devices in practice. In order to make those skilled in the art understand the present invention better, a kind of example of code operation is provided below:

Assuming that the video monitor is configured with a SIM card, and is set with a code (function start/exit) key; the monitoring terminal is a mobile phone (also equipped with a SIM card), then press the code key once to enter the code state, enter the code pairing After the code state, use the mobile phone to dial the SIM card number of the video monitor to start the code pairing operation. If the prompt tone heard on the mobile phone is that the call is in progress, it means the code pairing operation is successful; otherwise, it is unsuccessful. After entering the code pairing state, multiple code pairing operations can be performed continuously (for example, it supports up to 1 video monitor and 10 mobile phone numbers for code pairing), and finally press the code pairing key again to realize the code pairing operation of multiple mobile phones at one time . the

As an example of a specific application, the identification information of the video monitor involved in the association information may be a SIM card number, the network address information of the video monitor may be a temporary IP address, and the identification information of the monitoring terminal may be Identify SIM card number for user identity. the

Specifically, when the video monitor is connected to the wireless Internet through a wireless communication network (such as 2G network or 3G network), it will obtain a temporary IP address of the public network, and the video monitor will immediately assign the temporary IP address to its own The SIM card number and the monitoring terminal SIM card number successfully registered with the code are registered in the authentication server. The record module of the authentication server will write this registration information into the database (such as mysql database). the

A main application of the present invention lies in the realization of the remote alarm function. In order to realize this function, in the embodiment of the present invention, it is necessary to pre-configure the alarm monitoring information through the alarm configuration module in the monitoring terminal, and the alarm monitoring information includes the associated video monitor information; The device is placed in the active state. In practice, the alarm sensing device of the video monitor may include an infrared sensing device and/or a sensing device, such as a temperature sensor, a photosensitive sensor, a magnetic door sensor, a smoke detector, a gas sensor, an infrared sensing probe, etc., Alarm parameters or alarm conditions are generally set in the alarm sensing device, once the parameters are exceeded or the conditions are reached, an alarm signal will be automatically generated. For example, for a door magnetic sensor installed on a door, if someone touches the door when it is activated, an alarm signal will be generated; When entering from the window, an alarm signal will be generated; or, for example, for a place using a gas sensor alarm, when the gas leakage reaches a certain concentration, an alarm signal will be generated. the

For a system provided with multiple alarm sensing devices, the alarm signal may further include alarm source information to help the user determine where the abnormality occurs. the

In a specific application, the alarm sensing device can be arranged inside the video monitor, or outside the video monitor, or both inside and outside the video monitor. This is not limited. the

In order to improve the security of the data, reduce the requirement to the server, and reduce the load of the server, in the embodiment of the present invention, a large-capacity memory card, such as an SD card, is arranged in the video monitor. When the video monitor receives the When an alarm signal is generated by the alarm sensing device, the recording operation of the video data during the alarm is triggered by the memory card recording module, and the recorded alarm video data is stored in the memory card; for example, the video data at the time when the alarm signal is generated is recorded in D1 format video files and write them to the SD card. the

Due to the multi-device compatibility, pluggability and portability of the memory card itself, as an example of practical application, the video files in the memory card can be read and played back on different devices, so that users can Use video files anywhere. For example, on other computers, mobile phones. In this case, the wireless video monitoring system of the present invention (not necessarily at the video monitor end, can also be configured additionally, such as a PC connected to the monitor, so it is not limited to the video monitor, and the yellow part indicates Its application situation.) It can also include the following modules:

For example, when an alarm signal is received, the video monitor rings the coded mobile phone, and if the mobile phone hangs up after receiving the ringing, it means that the user has received the notification, and the video monitor notifies successfully; otherwise, the video monitor considers the notification unsuccessful. When the first code-pairing mobile phone cannot be successfully called through, it will initiate ringing to other code-pairing mobile phones associated one by one until a certain code-pairing mobile phone is successfully called through. If all associated code mobile phones can't be called through, then send a short message prompt to one or more code mobile phones in a certain place. the

When the monitoring terminal receives the alarm notification from the associated video monitor, it will start the monitoring mode through the startup module, such as the operation of hanging up the phone in the above example; in the monitoring mode, the user can submit a point-to-point communication request for the associated video monitor, After the request is processed by the authentication module of the authentication server, the connection between the current monitoring terminal and the corresponding video monitor can be realized. After the connection is completed, the monitoring terminal can realize point-to-point communication with the video monitor, for example, to perform video data transmission, control operations, and the like. the

In practice, the monitoring terminal can be a mobile phone, a notebook computer, a desktop computer that can be connected to a wired network, or a desktop computer equipped with a wireless network card, that is, the authentication server can support multiple login methods such as mobile phones, notebook computers, or PCs. connect. When the user submits the request for connecting the video monitor to the authentication server, the authentication server will use the information of the current monitoring terminal (such as the SIM card number on the mobile phone) and the information of the video monitor requesting connection (such as the SIM card number on the video monitor) card number) to query its database, if there is no record of the corresponding video monitor information, the result information of authentication failure will be returned; if there is corresponding video monitor information (such as temporary IP or domain name), then the authentication success message will be returned to the monitoring terminal result information. When the monitoring terminal receives the successful authentication result information from the authentication server, it can directly access the video monitor, and transmit image signals and control instructions in a point-to-point manner. the

As a preferred application mode for realizing the alarm function of the present invention, the operation request initiated by the monitoring terminal to the video monitor can be an alarm screen viewing request, and the following modules can also be set in the video monitor of the present invention:

The storage module is used to save the video data within the preset time range before and after the alarm signal is generated as the alarm picture information to the storage device;

For example, the video data of 5 seconds before and after the alarm signal is generated is stored in the storage device. In practical applications, the storage device may be a flash memory (FLASH). the

In this case, the response module may specifically include the following submodules:

Extraction sub-module, used to extract corresponding alarm screen information according to the alarm screen viewing request;

The transmission sub-module is used to transmit the alarm picture information to the monitoring terminal via the wireless communication network;

A processing sub-module is used to extract and compress corresponding video data according to the real-time video data acquisition request;

The transmission sub-module is used to transmit the compressed video data to the monitoring terminal via the wireless communication network;

In a specific implementation, the user can switch to the viewing state of the alarm screen as needed when viewing the real-time video, and automatically return to the viewing state of the real-time video after the alarm video is played. the

As an example of practical application, the video monitor can also be provided with a local alarm output module, which is used to connect an alarm to generate a local alarm signal. That is, the video monitor can be connected with sound, light, and electricity alarms inside or outside. When the alarm signal is received, it will not only alarm the user remotely, but also alarm locally. the

In order for those skilled in the art to better understand the present invention, the following uses the wireless video surveillance system of the present invention to perform a video surveillance process with an alarm as an example for illustration. the
