Detailed Description
The utility model provides a distribution network operation and maintenance process image monitoring device, it includes monitored control system, outdoor passive image monitoring device, and outdoor passive image monitoring device refers to: distribution network equipment environmental monitoring camera-guangzhou si tai information technology limited company, reference: 1. design and implementation of a GPRS network-based power distribution network video monitoring system in No. 14 and No. 3 of the academy of science and technology of North China; 2. the technology of enterprises and the application research of the electricity-taking technology of the current transformer in the 8 th (total 350 th) year in 2013 in the intelligent distribution network) are realized.
The indoor active image monitoring device (360D 706 type infrared camera) is respectively connected with a network video server (Haokangwei video DS-6601 HF-SATA) through a 4G wireless network; the network video server is connected with the monitoring system through the Ethernet.
The monitoring system is connected with the mobile monitoring terminal through a 4G wireless network.
The outdoor passive image monitoring device and the indoor active image monitoring device are respectively connected with the camera device control unit; the camera control unit (SONY CCU-D50P) is connected with the network video server through a 4G wireless network.
Functional overview: the outdoor passive image monitoring device acquires images of key parts of important power distribution networks such as overhead lines, distribution areas and distribution transformers through the image acquisition unit, the images are uploaded to a background through the communication terminal, and the monitoring system judges abnormal conditions and gives an alarm. Various hidden dangers of the power distribution network are effectively avoided, the power supply reliability is improved, and the power distribution management level is improved. Outdoor passive image monitoring devices and monitoring devices such as overhead lines and transformer stations are mutually matched, the sensing capability of the power distribution network is greatly improved, and the operation and maintenance level of the power distribution network is improved.
Monitoring data: and (5) running images of the power distribution network.
The outdoor passive image monitoring device comprises an induction electricity taking module, an electricity storage module, a high-definition camera module, an infrared night vision module and a high-strength shell module, and can be used for taking pictures at a frequency of 1 time per hour, so that the requirement of long-time operation is met, and after the shooting is finished, the data is uploaded to realize an early warning function.
The indoor active image monitoring device adopts a conventional network camera (360D 706 type infrared camera), and generally comprises a lens, an image sensor, a sound sensor, an A/D converter, a controller network server, an external alarm, a control interface and the like.
The lens is a front end component of the network camera, and includes a fixed aperture, an auto zoom, and the like, and is similar to the analog camera.
The image sensor has two modes of CMOS and CCD. CMOS is a complementary metal oxide semiconductor, and CMOS is a semiconductor mainly made of two elements, i.e., silicon and germanium, and achieves basic functions through negatively and positively charged transistors on CMOS. The currents generated by these two complementary effects can be recorded and interpreted as images by the processing chip. The major advantage of CMOS for CCD is that it is very power efficient. Unlike CCD and CMOS circuits that consist of diodes, which have little static power dissipation. This makes CMOS consume only about 1/3 for a normal CCD, and a significant problem with CMOS is overheating due to too frequent current transitions when processing fast-switching images. The problem is not so great that the dark current suppression is good, and the occurrence of a noise is very likely if the suppression is not good.
The CCD image sensor is composed of photodiodes and transmission circuits thereof which are arranged on a monocrystalline silicon substrate in a two-dimensional manner. The photodiode converts light into electric charges, and the electric charges are transmitted and output through the conversion circuit.
The a/D converter functions to convert analog signals such as images and sounds into digital signals.
The camera control unit is the heart of the camera, which carries the management and control work for the camera. If the hardware compression coding is adopted, the control unit of the camera device is an independent component; if the software coding compression is adopted, the control unit of the camera shooting device is a DSP running the coding compression software, namely the two are combined into a whole.
The network video server provides the network function of the network camera, and adopts related network protocols such as RTP/RTCP, UDP, HTTP, TCP/IP and the like, so that a user is allowed to access the network camera from a personal computer by using a standard browser according to the IP address of the network camera, watch real-time images and control the lens and the pan-tilt of the camera.
The mobile monitoring terminal adopts a mobile phone, a tablet personal computer and the like and is connected with the monitoring system through a wireless Ethernet or a 4G wireless network; and remotely monitoring or controlling the site.
