Embodiment Construction

[0059] The core idea of ​​the present invention is: send an alarm event subscription message to the PU through the CMS, so that the PU notifies the alarm event to the CU in real time through a specific multicast message and port, and notifies the CMS to archive the alarm event through a specific TCP message and port; According to the service authority level corresponding to the CU user and the service-related PU, the CMS determines the multicast group addresses corresponding to which alarm events of which PUs the user needs to subscribe to; if the service level of the user changes, the CMS needs the authority to receive alarms for the CU Make changes, send a notification message to the CU, and modify and update the multicast group address corresponding to the alarm event.

[0060] The present invention restructures the star network structure of the original video monitoring system into a full mesh structure for real-time alarm event multicast transmission and a star structure f...

Abstract

The invention discloses an alarming processing method and a device for a mixed structure, which is applied to a system including a central management server, a front terminal unit and a client terminal unit; the method comprises the following steps: the central management server collocates a corresponding relation between an alarming event and a multicast address; the central management server transmits alarming event subscription information to the front terminal unit; the subscription information carries the alarming event and the corresponding multicast address to lead the front terminal unit to generate the collected alarming event into a multicast message and transmit the message to the client terminal unit which is added into the multicast group of the multicast address. The alarming processing method and the device for the mixed structure reduce the alarming distribution pressure of CMS and guarantee the reliability of processing other monitoring services for one hand, and also reduce the distribution time of CMS as well as increase the timeliness of the alarming information and the reliability of the whole alarming system for the other hand.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to a method and equipment for alarm processing with a hybrid structure. Background technique [0002] The video surveillance system is the core component of the urban security system. The video surveillance system has experienced three stages: the analog video surveillance system, the digital-analog combined video surveillance system, and the all-digital remote networked video surveillance system. Disadvantages of traditional analog video surveillance systems are cumbersome maintenance, inability to access remotely, inability to integrate effectively with other security systems, and video quality degradation over time. The digital video surveillance system improves the user's ability to process video information, and makes it easier to search for alarm events and pre-event / post-event alarm information. From the perspective of development trend, large-scale video su...
