Method for achieving transformer substation video monitoring system on basis of ONVIF protocol

Abstract

The invention discloses a method for achieving a transformer substation video monitoring system on basis of an ONVIF protocol. The method relates to an IP camera, a network switch, a video processing unit, a storage server, an administration client and a monitoring client, wherein the pan-tilt control signal input end, the OSD configuration signal input end and the equipment configuration control signal input end of the IP camera are connected with the pan-tilt control signal output end, the OSD configuration signal output end and the equipment configuration control signal output end of the video processing unit respectively. The ONVIF protocol is extended in the transformer substation video monitor station end system. OSD configuration provides the function that the clients can control and configure screen information of the IP camera, and according to the function, various types of OSD configuration parameters such as characters, data and time can be displayed on a screen. A shielding and detecting function can analyze whether a picture is shielded, and an ONVIF analysis module expression language can be used for describing configuration information of a shielding engine module, judging whether a detected area is shielded and determining whether a video shielding phenomenon occurs.

Description

technical field [0001] The invention relates to a substation video monitoring system, in particular to an implementation method of the substation video monitoring system based on the ONVIF protocol. Background technique [0002] With the rapid development of network technology, digital video surveillance technology has been rapidly improved, and video surveillance is in the era of IP network surveillance. In the power system, more and more departments hope to use the new means of "remote viewing" to improve the monitoring level of substations. At present, in the construction of digital video surveillance system, the communication between the video processing unit and the IP camera is mostly connected by way of SDK. With the system construction, the shortcomings of this method begin to become prominent, so the unified interface standard will reduce a lot of repetitive development work. Solve the problem of incompatibility between different devices. At present, there are no ...
