Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the synchronization efficiency of the monitoring data, embodiments of the present invention provide a data synchronization system and method, which are described in detail below.
Fig. 1 is a schematic structural diagram of a data synchronization system according to an embodiment of the present invention, and as shown in fig. 1, the system according to the embodiment of the present invention includes a front-end individual device and a back-end network hard disk recorder.
And the individual equipment 110 is used for collecting monitoring data.
The monitoring data collected by the individual device may include, but is not limited to, a monitoring video, a monitoring picture, alarm information, log information, and the like.
And the network hard disk video recorder 120 is used for establishing connection with the individual soldier equipment, adding the individual soldier equipment as a data channel, and acquiring monitoring data acquired by the individual soldier equipment by using the data channel.
During specific implementation, the network video recorder can be connected with a plurality of individual soldier devices, so that an operator can inquire monitoring data collected by the individual soldier devices by operating one network video recorder. The individual equipment is added into the data channel of the network video recorder, so that the individual equipment is managed on the network video recorder in an equipment form, the network video recorder can directly realize management functions of data acquisition, data query, video recording and the like of the individual equipment through the data channel, and other additional complex platforms are not needed for supporting data transmission. And the network hard disk video recorder and the individual soldier equipment are matched for use, so that synchronous data can be realized, the local storage space of the individual soldier equipment is saved, and the network bandwidth occupation is reduced.
The data synchronization system provided by the embodiment of the invention comprises individual soldier equipment at the front end and a network hard disk video recorder at the rear end; the individual equipment is used for collecting monitoring data; and the network hard disk video recorder is used for establishing connection with the individual soldier equipment, adding the individual soldier equipment as a data channel, and acquiring monitoring data acquired by the individual soldier equipment by using the data channel. The individual soldier equipment is added into the data channel of the network video recorder, so that the individual soldier equipment is managed on the network video recorder in an equipment form, the network video recorder can directly realize management functions of data acquisition, data query, video recording and the like of the individual soldier equipment through the data channel, the structure of the system is simplified, and the synchronization efficiency of monitoring data is improved.
As a way that can be realized, when the individual soldier device executes the "collecting monitoring data" in the above embodiment, the monitoring data can be collected for the individual soldier device offline; when the network hard disk video recorder executes the 'connection with the individual soldier equipment and adds the individual soldier equipment as a data channel' in the embodiment, the network hard disk video recorder can establish wired connection with the individual soldier equipment and add the individual soldier equipment as the data channel when the individual soldier equipment is added to the same local area network with the network hard disk video recorder. For example, the individual soldier device and the network hard disk video recorder are added to the same local area network, and after the individual soldier device is added to the network hard disk video recorder as a data channel, the data synchronization function of the data channel is started. Suppose that after an operator goes out for a while with the individual device (i.e., the individual device leaves the local area network environment before the individual device leaves), a large amount of monitoring data such as videos and pictures are recorded by the individual device. When the operator returns to the office with the individual device (i.e., the individual device returns to the previous local area network environment) and reconnects to the previous local area network, the network hard disk video recorder automatically searches the monitoring data recorded by the individual device, so as to perform data synchronization.
As a way that can be realized, the individual device is not in wired connection with the network hard disk video recorder, if the individual device is in a 4G network with a better network environment or in the same WIFI environment as the network hard disk video recorder, the individual device can obtain a wide area network IP (Internet Protocol Address) Address of the network hard disk video recorder, and send a connection request to the network hard disk video recorder based on the wide area network IP Address; at this time, the network hard disk video recorder executes the steps of establishing connection with the individual soldier equipment and adding the individual soldier equipment as a data channel in the embodiment, and can establish wireless connection with the individual soldier equipment according to the connection request for the network hard disk video recorder and add the individual soldier equipment as the data channel. For example, if the network environment where the operator carries the individual soldier device to go out for office is good, the network hard disk video recorder can provide a wide area network IP address, the operator can manually register the network hard disk video recorder (the operator manually configures the wide area network IP address of the network hard disk video recorder on the individual soldier device) on the individual soldier device by using a GB28181 (a standard for security video monitoring networking system information transmission, exchange and control) protocol, and the network hard disk video recorder adds the individual soldier device as a data channel.
As a way to be realized, when the network hard disk recorder utilizes the data channel to acquire the monitoring data acquired by the individual soldier's equipment, specifically, when the data synchronization function of the data channel is turned on, the monitoring data acquired by the individual soldier's equipment is acquired. Of course, when the individual device is added as a data channel of the network hard disk video recorder, the data synchronization function can be automatically started, and the monitoring data can be synchronized to the network hard disk video recorder as long as the individual device acquires the monitoring data.
As one implementation manner, the network hard disk recorder may include a channel management unit that performs a data channel addition method. Fig. 2 is a schematic flow chart of a data channel adding method according to an embodiment of the present invention, and as shown in fig. 2, the data channel adding method includes:
s201, the channel management unit logs in the individual soldier equipment through a preset protocol.
The preset protocol may be the GB28181 protocol mentioned above, or may be a proprietary protocol.
S202, the channel management unit obtains configuration parameters of the individual soldier equipment.
The configuration parameters of the individual device can comprise two parts: software capabilities and hardware capabilities of individual devices. The software capability of the individual equipment can comprise code stream parameters, a synchronous data function, an alarm processing function and the like; the hardware capabilities of the individual devices may include multiple channels, connectivity network functions, etc.
S203, when the configuration parameters meet the preset data synchronization conditions, the channel management unit selects the appointed shooting channel of the individual soldier equipment to be added as the data channel of the network video recorder.
When the individual soldier equipment has the data synchronization function, the network hard disk video recorder can perform data synchronization with the individual soldier equipment. Specifically, the individual device may include different cameras (shooting channels) at a plurality of angles, and the network hard disk camera may select a plurality of designated shooting channels of the individual device to be added as data channels.
As a possible implementation manner, on the basis of the channel adding method, the channel management unit may further store configuration information of a data channel. The configuration information of the data channel here may include information specifying a shooting channel, for example, the individual soldier device includes a camera 1, a camera 2, a camera 3 and a camera 4, and the network hard disk camera may select the camera 1 and the camera 2 of the individual soldier device to be added as the data channel and store the relevant information of the camera 1 and the camera 2.
Therefore, by applying the embodiment of the invention, when the configuration parameters meet the preset data synchronization conditions, the appointed shooting channel of the individual soldier equipment is selected to be added as the data channel of the network video recorder, so that after the network video recorder is restarted, the appointed shooting channel can be directly added as the data channel of the network video recorder, and the monitoring data acquired by the individual soldier equipment can be rapidly acquired by utilizing the data channel.
As an implementation manner, the network hard disk recorder may include a timing unit, and the timing unit performs the data channel timing method. Fig. 3 is a schematic flow chart of a data channel timing method according to an embodiment of the present invention, and as shown in fig. 3, the data channel timing method includes:
and S301, the time correcting unit sends the current time of the network hard disk video recorder to the individual soldier equipment.
S302, when the individual soldier equipment receives the current time of the network video recorder, if the current time of the network video recorder is inconsistent with the local current time of the individual soldier equipment, the local current time is updated to be the current time of the network video recorder.
Therefore, by judging whether the current time of the network hard disk video recorder is consistent with the local current time of the individual equipment or not, if not, the local current time is updated to be the current time of the network hard disk video recorder, so that the current time of the network hard disk video recorder is consistent with the current time of the individual equipment, the data synchronization time of the network hard disk video recorder is consistent with the data synchronization time of the individual equipment, and the accuracy of monitoring data synchronization is improved.
As one way of implementation, the network hard disk recorder described above may include a data synchronization unit that performs the data synchronization method. Fig. 4 is a schematic flowchart of a data synchronization method according to an embodiment of the present invention, and as shown in fig. 4, the data synchronization method includes:
s401, the data synchronization unit judges whether the state of the data channel is on-line.
If not, execute 402; if yes, executing S403;
s402, the data synchronization unit records the offline time period.
The period of the data channel which is not on-line refers to the moment that the individual soldier equipment is not on-line from the beginning to the moment that the individual soldier equipment is on-line again. In particular implementations, the off-line time period of the data channel may have multiple segments.
And S403, the data synchronization unit receives real-time monitoring data sent by the individual soldier equipment, sends the recorded offline time period to the individual soldier equipment, and receives monitoring data corresponding to the offline time period sent by the individual soldier equipment.
The following describes the data synchronization method with a specific example: in the time period of 9 o 'clock-10 o' clock of 11.20.2019, the state of the individual soldier equipment is off-line, so the network hard disk video recorder cannot acquire the monitoring data acquired by the individual soldier equipment in the time period. The network hard disk video recorder can record the offline time period of the individual soldier equipment of 9 o 'clock-10 o' clock in 11 months and 20 days in 2019, and after the individual soldier equipment is online again, the network hard disk video recorder sends the offline time period of the individual soldier equipment to the individual soldier equipment, and the individual soldier equipment sends monitoring data corresponding to the offline time period of 9 o 'clock-10 o' clock in 11 months and 20 days in 2019 to the network hard disk video recorder based on the received time period.
Therefore, by applying the embodiment of the invention, the state information of the data channel is obtained; if the state of the data channel is offline, recording an offline time period; if the state of the data channel is on-line, the real-time monitoring data sent by the individual soldier equipment is received, the recorded off-line time period is sent to the individual soldier equipment, the monitoring data corresponding to the off-line time period sent by the individual soldier equipment is received, the monitoring data of the individual soldier equipment can be ensured to be consistent with the monitoring data obtained by the network hard disk video recorder, and therefore the synchronization accuracy of the monitoring data is improved.
As one way of implementation, the network hard disk recorder may include an intelligent analysis unit that performs the data analysis method. Fig. 5 is a schematic flow chart of a data analysis method according to an embodiment of the present invention, and as shown in fig. 5, the data analysis method includes:
s501, the intelligent analysis unit acquires type information for performing data analysis in advance.
S502, the intelligent analysis unit analyzes the monitoring data by using the analysis rule corresponding to the type information to obtain a data analysis result.
In a specific implementation, the data analysis method may be as follows: the network video recorder can have three types of information, namely face recognition, feature analysis and data structuring, and after an operator selects one type from the three types, the intelligent analysis unit analyzes the monitoring data by using an analysis rule corresponding to the type.
For example, the type information subjected to data analysis is face recognition, a face of a target person can be detected from monitoring data obtained by individual soldier equipment, a face model of the target person is generated, the face model of the target person is matched with a face model in a face database of criminals, and if the similarity between the face model of the target person and a certain face model in the face database is greater than a preset threshold value, the target person is determined to be the criminal; or if the absolute value of the difference value between the interpupillary distance of the target person and the interpupillary distance of a person in the face database is smaller than a preset interpupillary distance threshold value, determining that the target person is a criminal.
The data analysis may be a process of continuously looping analysis until the operator turns off the analysis task or there is no new data to analyze, and the data analysis is stopped.
Therefore, by applying the embodiment of the invention, the type information of the data analysis to be performed is obtained through the intelligent analysis unit; the monitoring data are analyzed by using the analysis rule corresponding to the type information to obtain a data analysis result, so that the data analysis efficiency is improved.
As a possible implementation manner, after the data analysis result is obtained in the data analysis method executed by the intelligent analysis unit, the network hard disk recorder may further include an alarm processing unit, and the alarm processing unit executes the alarm processing method. Fig. 6 is a schematic flow chart of an alarm processing method according to an embodiment of the present invention, and as shown in fig. 6, the alarm processing method includes:
s601, the alarm processing unit processes the data analysis result according to the preset alarm processing rule to obtain an alarm processing result.
S602, the alarm processing unit records the alarm processing result.
And S603, generating alarm information by the alarm processing unit according to the alarm processing result, and sending the alarm information to the individual soldier equipment.
During specific implementation, the requirement of a pre-configured alarm processing rule is met by processing a data analysis result. For example, the preconfigured alarm processing rule may be a linked local output popup frame of the network video recorder, and then the network video recorder needs to process the data analysis result, and after the alarm processing result is obtained, the network video recorder may generate alarm information according to the alarm processing result, and send the alarm information to the individual soldier device. The pre-configured alarm processing rules can also be used for adding information for updating monitoring data, generating summary information of monitoring videos and the like. Meanwhile, the alarm processing unit can also locally record the alarm processing result, so that an operator can perform back check or backtrack the alarm processing process and the like on the event.
As one way of implementation, the network hard disk recorder may include an intelligent retrieval unit that performs a data retrieval method. Fig. 7 is a schematic flowchart of a data retrieval method according to an embodiment of the present invention, and as shown in fig. 7, the data retrieval method includes:
s701, the intelligent retrieval unit receives the retrieval filtering conditions and searches data meeting the retrieval filtering conditions from the network video recorder.
S702, the intelligent retrieval unit feeds back the searched data.
The data searched by the intelligent retrieval unit can be a data analysis result, an alarm processing result, a data analysis result and an alarm processing result. In a specific implementation, the network hard disk recorder may store related data of multiple types and multiple events, such as picture data, log data, video, alarm information, and the like, and the search filtering condition may be, for example, alarm information, log information, picture information, video summary, and the like. If the retrieval filtering condition input by the operator is an alarm processing result, the intelligent retrieval unit feeds back the searched data from the network video recorder, wherein the searched data can be alarm time, alarm video, alarm pictures and the like.
A specific implementation manner is taken as an example to describe the data synchronization system provided in the embodiment of the present invention, fig. 8 is a schematic structural diagram of another data synchronization system provided in the embodiment of the present invention, as shown in fig. 8, the system of the embodiment of the present invention includes a front-end individual device and a back-end network hard disk recorder, where the individual device includes a first alarm processing unit 810 and a first data synchronization unit 820; the network hard disk recorder includes a second alarm processing unit 830, a second data synchronization unit 840, a channel management unit 850, an intelligent analysis unit 860, and an intelligent retrieval unit 870.
