Embodiment
Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of video monitoring system for substation, is made up of video acquisition device, data transmission device, alarm device, Surveillance center, induction installation and remote control center.
Video acquisition device by data transmission device by video data transmission to Surveillance center, the sensed data of transformer station inside is transferred to Surveillance center by induction installation, Surveillance center is by storing sensed data, video data, remote control center obtains sensed data, the video data of Surveillance center by network, judge by analyzing, when abnormal conditions appear in data, control Surveillance center and start alarm device and notify maintenance personal's on-call maintenance.
Video acquisition device comprises IP network video camera, for the video data of acquisition monitoring transformer station.IP network shooting function more simply realizes monitoring particularly remote monitoring, more simply constructs and safeguard, better support audio frequency, better support alarm linkage, to record a video storage, the video effect of the selection of abundanter product, more high definition and more perfect monitoring management more flexibly.In addition, IPC supports that WIFI wireless access, 3G access, POE powers and intelligent acess.IP network video camera is the digitizer of transmission Network Based, and IP network video camera, except having common composite video signal output interface BNC, also has networking output interface, can directly by IP network video camera access local area network.
Induction installation comprises temperature sensor, humidity sensor, water sensor, Smoke Sensor, pressure sensor, SF6 transducer and dust sensor etc., be respectively used to detect the environmental data such as temperature, humidity, immersion, smog, pressure, sulphur hexafluoride, dust in transformer station, and these data are sent to Surveillance center by data transmission device.Temperature sensor adopts non-contact temperature sensor, measures the upper limit not by the restriction of temperature-sensing element heatproof degree, does not thus limit in principle the highest observable temperature.For more than 1800 DEG C high temperature, main employing non-contact temperature measuring method.Along with the development of infrared technique, radiation temperature measurement is expanded to infrared ray by visible ray gradually, less than 700 DEG C until normal temperature adopts all, and resolution is very high.Water sensor adopts non-contact type water soaked transducer, utilizes the refraction of light in different medium cross section and principle of reflection to detect.Smoke Sensor ion type smog transducer, has the advantages that working stability is reliable, highly sensitive.
