(III) physical connection
Because the video monitoring system and the automatic control system management host both support the Ethernet, in the embodiment of the invention, the physical connection between the video monitoring system and the automatic control system is designed to be connected in an Ethernet mode, the video encoder and the automatic control system management host are accessed into the same Ethernet, the IP addresses of the video encoder and the automatic control system management host are ensured to be in the same network segment, the video encoder and the automatic control system management host are configured with the same mask and gateway addresses, the network can adopt a public network address or a private network address, and in order to ensure the corresponding relation of the automatic control management host and the video encoder, the video encoder and the automatic control management host can be configured into fixed IP addresses (namely static IP addresses).
In the specific implementation process, the automatic control management configuration software may be installed in a PC in advance, and then the corresponding relationship between the monitoring and control point location of the automatic control system and the video encoder is configured, including: configuring unique identification such as IP address and channel ID of the coding device, and configuration items such as real-time data type to be transmitted to the video monitoring system, after the automatic control management host computer is started, actively initiating the establishment of TCP long connection to the associated video monitoring coding device, keeping heartbeat (namely keeping alive), and regularly checking the working states (on-line or off-line) of the video encoder and the management host computer.
According to an embodiment of the present invention, a management method of an automatic control system is provided.
Fig. 1 is a process flow chart of a management method of an automatic control system according to an embodiment of the present invention, and as shown in fig. 1, the management method of an automatic control system according to an embodiment of the present invention mainly includes the following processes (step S101 to step S103):
step S101: the video monitoring system receives an image shooting request from the automatic control system and shoots an image, wherein the image shooting request carries key information of the automatic control system;
step S103: and the video monitoring system overlaps the key information carried in the image shooting request with the shot image data, and stores the image data obtained after overlapping in a correlation manner with the key information.
The details of each of the above-described processes are further described below.
Step S101
In a specific implementation process, the processing of step S101 may be triggered by the following method: the automatic control management host of the automatic control system judges whether the data exceeds the standard or not according to the data received from the field controller, namely judges whether the data is abnormal or not at present, and sends an image shooting request to a video encoder under the condition that the data is judged to be abnormal, and the image shooting request carries key information of the automatic control system, such as fault information, position information of a monitoring or control point, time information, equipment information, alarm level, information type and the like.
And after receiving the image shooting request, the video encoder controls an imaging device in the video control system to shoot or record the image. In the implementation process, the number of continuous snapshots and the time interval can be set.
The above-mentioned judging whether the abnormality occurs currently includes the following two aspects:
various sensing elements hung below a field controller of the automatic control system collect various information, such as analog quantity information of current, voltage, temperature, humidity and the like and switching value information of switching state, liquid level height and the like. And the field controller of the automatic control system judges whether the acquired data is normal or not, whether the equipment state is normal or not or whether the acquired data does not exceed the standard or not according to a preset threshold value, if not, alarm information is generated, detailed information related to the alarm information and all real-time data are uploaded to a management host of the automatic control system, and the management host determines that the abnormality occurs currently according to the judgment result.
And (II) judging that the abnormality occurs in the currently acquired real-time data, but the statistical value or the average value of the real-time data in a period of time exceeds the standard. Specifically, the field controller of the automatic control system uploads all real-time data to the management host of the automatic control system, the management host carries out statistics, analysis, processing and storage on the data, the management host of the automatic control system judges whether the statistical data are normal or not in preset time, and if the accumulated data exceed the standard, the current abnormity is determined.
In addition, in order to ensure time consistency between the digital video monitoring system and the automatic control system, time synchronization needs to be performed on the automatic control system and the video monitoring system.
In a specific implementation process, when the automatic control system management host and a video encoder of the video control system perform keep-alive check, time synchronization information may be periodically sent to the video monitoring system, so as to implement time synchronization between the automatic control system management host and the video control system, and specifically, the method may include the following steps:
step 1: the method comprises the steps that an automatic control system management host periodically sends time synchronization information to a video monitoring system, wherein the time synchronization information carries a current time mark of the automatic control system;
step 2: the video monitoring system judges whether the time of the video monitoring system is consistent with that of the automatic control system or not according to the time mark, and returns the current time of the video monitoring system to the automatic control system under the condition that the judgment result is negative;
and step 3: and the automatic control system management host adjusts the local time according to the current time returned by the video control system.
And the video monitoring system is connected with the Internet network, and a video monitoring system platform can be set to actively synchronize with a time server on the Internet network so as to ensure the uniformity and accuracy of the clock of the whole integrated system.
(II) step S103
The video encoder superimposes the key information acquired from the image shooting request onto the picture or video captured by the imaging device, and stores the image data obtained after superimposition in association with the key information, and during the specific implementation process, the image data and the key information associated therewith may be stored in the form of a relational database, for example, the relational data table shown in fig. 1 may be stored.
TABLE 1 Association of image data and Key information
| Serial number | Position of control point | Time of day | ...... | Picture frame | Video recording |
| 1 | 00121 | 2008.10.153:25pm | ...... | 001.jpg002.jpg | 001.wma |
| ....... | ....... | ...... | ...... | ...... | ...... |
| n | 00415 | 2008.10.1910:26am | 012.jpg | 002.wma |
In a specific implementation, the video encoder may upload the association relationship to a server (i.e., the mass storage device) for storage.
After the content is stored in association, the stored image data can be searched according to the key information, specifically, after the query type is selected, the client of the video monitoring system inputs the key information such as position information and time of the control point, and searches the image data corresponding to the input key information, namely, the captured image or video.
