Embodiment 1
[0049] S1, the user sends a parameter setting command through the interface provided by the main process of the client to set the parameter of a certain video device, and the main process receives the parameter setting command;
[0050] S2, the main process detects whether the sub-process corresponding to the video device has been started, and if not started, then starts the sub-process;
[0051] S3, if the corresponding sub-process has been started, the main process sends a parameter setting instruction to the sub-process;
[0052] After S3, the child process may not respond to the parameter setting command normally. The possible reasons include: the SDK provided by the video device manufacturer is poorly compatible, error-prone, frequent calls to the child process in a short period of time, a large number of concurrent operations, and video The equipment runs for a long time, and so on.
[0053] S4, if the sub-process cannot normally respond to the parameter setting instruc...
Embodiment 2
[0056] S'1, the user sends a monitoring device command through the interface provided by the main process of the client to receive the alarm information of a certain video device, and the main process receives the monitoring device command;
[0057] S'2, the main process detects whether the sub-process corresponding to the video device has been started, and if not started, then starts the sub-process;
[0058] S'3, if the corresponding sub-process has been started, the main process sends a monitoring device command to the sub-process;
[0059] S'4, after the child process receives the monitoring device instruction, it automatically monitors the information reported by the device to see if there is an alarm message to be reported, and sends normal information to the main process;
[0060] S'5, if the reported information is not received normally for a period of time, the child process sends an abnormal message to the main process;
[0061] S'6, the main process receives an abn...

Abstract
The invention is applied to the field of video monitors and particularly relates to a method, a device and a system for achieving compatibility among multiple video monitor equipment. When the method, the device and the system for achieving the compatibility among the multiple video monitor equipment are carried out, the method includes that operating orders sent by users are received, the operating orders are sent to sub-processes corresponding to the video monitor equipment through a uniform interface of a host process according to equipment types which are corresponding to the operating orders, the sub-processes are provided with interfaces corresponding with the uniform interface, and when the sub-processes do not normally respond to the operating orders, the sub-processes are reset to continue to send the operating orders to the sub-progresses. The method guaranteed the stability of a video monitor system when a software development kit (SDK) provided by a manufacturer producing the video monitor is abnormal. Due to the fact that each sub-process corresponding to each monitor device is provided with the interface corresponding to the uniform interface, when another monitor device is added, only the SDK is needed to be added with a corresponding sub-process, and therefore strong independency and good expansibility of the video monitor system are guaranteed.
Description
technical field [0001] The invention belongs to the field of video monitoring, and in particular relates to a method, device and system for realizing the compatibility of various video monitoring equipment. Background technique [0002] The video surveillance system is a comprehensive system with strong preventive capabilities, and it is also an important part of the security system. Video surveillance system is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, as the domestic demand for video surveillance continues to increase, video equipment manufacturers have also continued to grow. However, due to the relatively short development time of the security industry, a complete industry standard has not yet been formed. Various video equipment manufacturers have formulated their own corresponding enterprise standards according to the development of their respective enterprises, and thus formed different...
