[0060] Embodiment two

[0061] Figure 3 The flowchart of the control of the network video recorder in the embodiment two is optimized based on the above-mentioned embodiment. The optimization is as follows: if a control instruction of a second network video recorder is detected, a connection request is initiated to the second network video recorder, and a connection response of the second network video recorder is received, which comprises: in a window picture of a first network video recorder, if a viewing operation of a channel management interface is received, all network video recorders of a current monitoring system are queried to obtain a network video recorder list; a second network video recorder is determined in response to a selection operation in the network video recorder list; a connection request is initiated to the second network video recorder, and a connection response of the second network video recorder is received to establish a TCP connection with a service module of the second network video recorder.

[0062] As shown in Figure 3 The method of the embodiment specifically comprises the following steps:

[0063] S310, in a window picture of a first network video recorder, if a viewing operation of a channel management interface is received, all network video recorders of a current monitoring system are queried to obtain a network video recorder list.

[0064] The window picture can be a picture in which a staff member operates and views video monitoring content in real time. The channel management interface can be a function interface in the first network video recorder. The viewing operation can be an operation of viewing each network video recorder currently under the same network. The all network video recorders can be all network video recorders in the same network as the first network video recorder. The network video recorder list can include a list of parameter information of all network video recorder devices in the same network.

[0065] In the embodiment, when the channel management interface receives the viewing operation of the network video recorder currently under the same network, all network video recorders in the same network as the first network video recorder in the current monitoring system are queried, so that the parameter information of all network video recorder devices is obtained.

[0066] S320, in response to a selection operation in the network video recorder list, a second network video recorder is determined.

[0067] The selection operation can be selection of the second network video recorder in the network video recorder list. The selectable second network video recorder can be one or multiple, and only one second network video recorder can be selected each time. In the embodiment, the channel management interface is entered in the display interface of the first network video recorder to select the network video recorder list, so that the second network video recorder is determined.

[0068] S330, a connection request is initiated to the second network video recorder, and a connection response of the second network video recorder is received to establish a TCP connection with a service module of the second network video recorder.

[0069] The connection request can be initiated by the man-machine interaction module of the first network video recorder.

[0071] The first network video recorder adds a control mark to the human-computer interaction module to stop the human-computer interaction module from obtaining service data from the service module of the first network video recorder.

[0072] The control mark can be a control state flag CF. In this embodiment, after the service module of the second network video recorder receives the connection request and establishes a TCP connection with the human-computer interaction module of the first network video recorder, the human-computer interaction module of the first network video recorder enters the control state flag CF. After the human-computer interaction module of the first network video recorder enters the control state flag CF, the human-computer interaction module of the first network video recorder stops obtaining service data from the service module of the first network video recorder. In addition, when the human-computer interaction module of the first network video recorder is in the CF state, the CF state can be exited by, for example, right-clicking twice with a mouse, the human-computer interaction module of the first network video recorder disconnects from the second network video recorder, re-interacts with the service module of the first network video recorder, and returns to the display screen of the first network video recorder. In this embodiment, by adding the control mark, the source of the service data obtained by the human-computer interaction module of the first network video recorder can be switched, and the control operation is facilitated.

[0073] S340, a service data query request is initiated to the service module of the second network video recorder to obtain the service data of the second network video recorder.

[0074] The service data query request can be initiated by the human-computer interaction module of the first network video recorder. In this embodiment, the human-computer interaction module of the first network video recorder establishes a connection with the human-computer interaction module and the service module of the second network video recorder through the TCP protocol; the human-computer interaction module of the first network video recorder jumps to the main menu interface and initiates a service data query request to the service module of the second network video recorder to obtain the service data of the second network video recorder.

[0075] S350, the service data is parsed by the human-computer interaction module of the first network video recorder.

[0076] In this embodiment, the processing device on the display device connected to the first network video recorder further includes a data analysis module; the data analysis module can return the service data of the second network video recorder to the first network video recorder. Then the service data of the second network video recorder is parsed by the human-computer interaction module of the first network video recorder.

[0077] S360, receiving the service data of the second network video recorder, and displaying the human-computer interface of the second network video recorder.

[0078] S370, displaying the configuration data.

[0079] In this embodiment, the configuration data parsed by the human-computer interaction module of the first network video recorder is displayed on the human-computer control of the first network video recorder. At this time, the display device displays the same human-computer interface as the human-computer interaction module of the second network video recorder.

[0080] S380, obtaining updated configuration data in response to a configuration operation.

[0081] The configuration operation can be initiated by the human-computer interaction module of the first network video recorder and responded by the service data module of the second network video recorder. The configuration data can be configuration encoding parameters, alarms, networks, intelligence, storage, etc. In this embodiment, the staff can perform any configuration operation on the human-computer interaction module of the first network video recorder to obtain updated configuration data.

[0082] S390, sending the updated configuration data to the second network video recorder to control the second network video recorder.

[0083] In this embodiment, any configuration operation is performed on the human-computer interaction module of the first network video recorder. The configuration of the service data to be sent is sent by the human-computer interaction module of the first network video recorder to the service data module of the second network video recorder. The service data module of the second network video recorder is saved to the configuration area of the second network video recorder after corresponding data processing, thereby realizing the control of the second network video recorder.

[0084] For example, the interaction flow timing chart of the first network video recorder and the second network video recorder is shown in Figure 4 In this embodiment, the first network video recorder is taken as the monitoring device 1, and the second network video recorder is taken as the monitoring device 2. The human-computer interaction module of the first network video recorder is denoted as MMI1, and the service module of the second network video recorder is denoted as CORE2.

[0085] Step description:

[0086] F1: MMI1 selects the control device to enter the control state.

[0087] F2: MMI1 establishes a TCP connection with CORE2.

[0088] F3: CORE2 returns connection success.

[0089] F4: MMI1 queries service data.

[0090] F5: returns service data of CORE2.

[0091] F6: displays CORE2 data based on MMI1 man-machine interface.

[0092] F7: operates at MMI1 and sends configuration data.

[0093] F8: returns data reception success.

[0094] F9: disconnects.

[0095] F10: MMI1 exits control state and restores original man-machine interface.

[0096] The technical scheme provided by the embodiment of the application can, in a complex network video recorder networking environment, when it is necessary to modify the man-machine configuration of a network video recorder, freely switch control of any network video recorder in the network without needing to pass through each corresponding display device, but only using the network video recorder display device of one of the network video recorders, thereby greatly reducing the complexity of user operation configuration and improving the use efficiency of the network video recorder.

[0097] In the embodiment, the updated configuration data is optionally sent to the second network video recorder to control the second network video recorder, including:

[0098] The updated configuration data is sent to the second network video recorder for the second network video recorder to perform configuration update based on the updated configuration data.

[0099] The service data of the second network video recorder is refreshed to be displayed based on the configuration update result.

[0100] In the embodiment, the man-machine interaction module of the first network video recorder sends the updated configuration data to the service module of the second network video recorder, so that the second network video recorder is configured according to the updated configuration data. When the interface of the man-machine interaction module of the first network video recorder is switched, the interface display of the man-machine interaction module of the first network video recorder is refreshed; after the configuration of the second network video recorder is completed, the man-machine interaction module of the first network video recorder sends a configuration message to notify the man-machine interaction module of the second network video recorder to re-read the configuration data, and the service data of the second network video recorder is refreshed; then the configuration update result is displayed in the interface of the man-machine interaction module of the second network video recorder, and the data reception success is returned to the first network video recorder; then the man-machine interaction module of the first network video recorder disconnects the TCP connection, and exits the control state to restore the original man-machine interface. Exemplarily, the configuration message can be an AF message. In the embodiment, the updated configuration data of the first network video recorder can be sent to the second network video recorder and displayed, so that the control of the second network video recorder is realized, which is more convenient and fast.

[0101] In the embodiment, optionally, the parsing the service data comprises parsing video data in the service data.

[0102] Correspondingly, the method further comprises:
