Problems solved by technology

[0004] For the control method combining centralized and distributed, all connections with the controlled equipment are maintained by the centralized PTZ control node, which occupies a large amount of resources of the centralized PTZ control node, making the centralized cloud The operation efficiency of the platform control node is low, which is not conducive to the timely progress of the platform control work

Embodiment Construction

[0019] In a centralized and distributed PTZ management system, the centralized PTZ control node needs to maintain more connections. If a persistent connection is maintained for each controlled device, more system resources will be occupied, especially when a controlled device does not need to be controlled, or is controlled for a small number of times, resulting in a waste of system resources. If only a short connection is maintained, that is, whenever a distributed PTZ control node initiates a control request for a controlled device, the centralized PTZ control node establishes a connection with the corresponding controlled device, and releases the connection after the control ends . This method will cause that when a controlled device is frequently controlled, the centralized PTZ control node needs to repeatedly establish a connection with the controlled device, and the establishment and release of the connection need to consume more system resources and time, resulting in ...

Abstract

The invention discloses a pan-tilt control method, system and centralized pan-tilt control node. In the centralized and distributed pan-tilt control system, the centralized pan-tilt control node optimizes the connection with the controlled equipment, If there is no distributed PTZ control node to initiate control to a controlled device within the predetermined time, it means that the controlled device has a low degree of attention, then release the connection with the controlled device; if there is a distributed control node within the predetermined time When a controlled device initiates control, the connection with the controlled device is maintained and the predetermined time is extended. In this way, the number of connections required to be maintained by the centralized PTZ control node is reduced, sufficient resources are reserved for frequently controlled devices, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of camera monitoring, in particular to a pan-tilt control method, system and centralized pan-tilt control node. Background technique [0002] In industries that need to be monitored, such as transportation and finance, multiple cameras are often used to monitor different areas. For the convenience of use, a camera that can be controlled by a pan-tilt is generally used, so different pan-tilt control methods are derived. The current mainstream PTZ control methods include centralized PTZ control methods, distributed PTZ control methods and control methods combining the two. The corresponding systems are introduced as follows. [0003] Centralized PTZ control system, such as figure 1 As shown, all controlled devices are controlled by a centralized PTZ control node. Distributed PTZ control system, such as figure 2 As shown, all controlled devices are controlled by multiple distributed PTZ control nodes, and ...
