Description
Technical field
The present invention relates to bank electricity field of video monitoring, particularly a kind of bank electricity wireless video monitoring system based on the WI-FI technology.
Background technology
Along with comprehensive speed-raising of China's port construction and greatly developing of boats and ships industry, it is to rely on to develop the economy that increasing port city all begins with the harbour.But because expanding port construction brings the berth to increase, thing followed pollutant emission and Diesel Generator Noise have been brought also for the harbor district environment and are had a strong impact on.For air pollution and the noise pollution that reduces harbor district and near zone thereof, increasing harbour uses the electricity substituted marine diesel generating of bank to the power supply of mooring a boat, and promptly adopts the land power supply to be the ship power supply that pulls in to shore, and this electric power system is called for short the bank electric system.
The bank power technology is through the mobile power-on box that is equipped with at harbour boats and ships to be supplied power at present; But because it is far away apart from the port dispatching Control Room to move power-on box; Dispatcher in the control room can't grasp in the wings promptly and accurately move the power-on box state, therefore adopts video monitoring can realize moving power-on box telemonitoring of bank electromigration and unattended operation preferably.But have mobility because of moving the junction box, so adopt the cable video monitoring can bring the problem of difficult wiring, and adopt wireless video monitoring can reduce the puzzlement of wiring, that the wireless technology of using at present has is infrared, bluetooth, GPRS etc.
Summary of the invention
The dispatcher promptly and accurately grasps the ruuning situation of the moving power-on box of bank electromigration in the dispatching and monitoring chamber for ease, the invention provides a kind of bank electricity wireless video monitoring system based on WI-FI.
To achieve these goals, technical scheme of the present invention is following:
A kind of bank electricity wireless video monitoring system is characterized in that, comprises
Be located at the IP Camera that moves on the power-on box,
The video monitoring client terminal that can show the video pictures that said IP Camera is gathered in real time,
The WI-FI radio transmitting device,
Said IP Camera is through said WI-FI radio transmitting device and the said video monitoring client terminal data interaction that is located at the dispatching and monitoring chamber.
Said WI-FI radio transmitting device comprises the WI-FI wireless network card.
Said WI-FI radio transmitting device is built in the said IP Camera, can be transferred to wireless network to the IP packet after the IP Camera encapsulation through wireless mode.
IP Camera comprises:
Video acquisition module is transformed into analog electrical signal through CCD with light signal, converts analog electrical signal to digital signal through the A/D conversion chip again;
Video encoding module; The uncoded digital signal of video acquisition module output is carried out the MPG4 coding, original video data is carried out source encoding, the data volume of compression original video; MPG4 coding versatility is better, and a lot of free devices all support to play the video file of MPG4 coding;
Storage inside module, IP Camera have the function of local stored video data, are used for storing the video data through the video encoding module coding into the SD card with the form of AVI;
Ftp client, if select the FTP mode to store data, the inner ftp client of IP Camera can store the video data of having encoded on the ftp server of dispatching and monitoring chamber appointment through the FTP mode, as historical video data backup;
The video server module is used for the video data of having encoded to the request of sending and the transmission of the video monitoring client terminal through authentication; When the video server module is received the monitor client sent request, carry out authentication earlier, authentication through after begin the video data of having encoded to monitor client transmission, the video server module can be provided with maximum number of connections;
The image recognition alarm module when bigger variation takes place the video pictures of monitoring, produces warning information and uploads to the dispatching and monitoring chamber;
The message response module is used for handling the message that produces when video monitoring client terminal issues request command or configuration order, and handles the IP Camera inside story.
Video monitoring client terminal comprises:
The video decode module is decoded to the video data stream of having encoded that transmits from IP Camera;
Video display module is used for the video pictures that the IP Camera monitoring of IP address has been imported in real-time demonstration;
Network conf iotag. module is used for the IP address of Configuration Online IP Camera, subnet mask, gateway information;
The stored configuration module is used to be provided with the memory location of the video data of having encoded, and the video data in storage a certain period can also be set.Can specify the video data that moves the power-on box duration of work to carry out real-time storage.
The memory location of the video data of having encoded comprises the SD card that IP Camera is inner, perhaps ftp server.Whether the data that are provided with behind the coding by the stored configuration module exist on the inner SD card of camera, perhaps store on the long-range ftp server through the FTP mode.
Video monitoring client terminal also comprises ftp server, be used for that the remote storage IP Camera gathers video data, said ftp server or be configured on same the PC, or use independently a PC as ftp server with video monitoring client terminal.
The image recognition alarm module interlock of the video display module of video monitoring client terminal and IP Camera.When IP Camera image recognition alarm module produced warning information, the real-time pictures of video display module can be glimmered automatically, reminded the dispatcher to note the generation of abnormal conditions.
The beneficial effect that the present invention produced:
Bank electricity wireless video monitoring system of the present invention uses the WI-FI technology, can satisfy the network bandwidth of HD video, and network delay is little; And can satisfy based on the wireless network of WI-FI technology and to move the wireless transmission distance of power-on box to the control room; WI-FI uses the free frequency range of 2.4GHz, therefore need pay extra-pay to operator unlike GPRS.The broadband that WI-FI has, wait characteristic in real time, reliably, cheaply; Therefore adopt based on the bank electricity wireless video monitoring system of WI-FI technology the moving power-on box of bank electromigration that harbour is equipped with is monitored in real time and alarmed; Make the dispatcher's grasp in the wings promptly and accurately in the port dispatching Control Room move the power-on box state; Guarantee to move power-on box boats and ships are supplied power, realize moving power-on box telemonitoring of bank electromigration and unattended operation.Avoided cable video in the port and pier difficult wiring, can satisfy the requirement of high definition IP Camera to the network bandwidth, real-time simultaneously, networking cost is lower.
Because what bank electricity wireless video monitoring adopted is that multiple spot is monitored simultaneously, and automatic alarm is provided, the video data that therefore need handle is bigger.The present invention accomplishes the processing and the analysis distribution of video data to each camera, the digital picture identification in the video monitoring is handled all and accomplished by the inner embedded system of IP Camera, has alleviated the burden of dispatching and monitoring chamber monitor client greatly.
Description of drawings
