Embodiment
For making that architectural feature of the present invention and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation.
Embodiment 1
Referring to Fig. 1 and Fig. 2, as shown in the figure, a kind of mobile monitor alarm method, comprises the steps:
(1) watch-dog obtains live audio, video, by audio signal and video signal transmission to DVR; Described watch-dog comprises video camera, pick-up, burglar alarm, microphone.
Wherein, the quantity of video camera is 1-4 platform, also can need to increase adjustment according to scene, video camera obtains live video, by video signal transmission, to DVR, pick-up, microphone, burglar alarm are used for obtaining live audio, and by audio transmission to DVR.
(2) DVR is understood audio signal and vision signal, and storage output audio signal and vision signal are to local monitor equipment and server end; Described server is provided with network with DVR and is connected;
Local monitor equipment receives AV signal, realizes local monitor, and monitor staff judges according to monitored picture whether monitored scene has extremely.Described DVR can be under the operational environment without external power supply continuous operation 2-3 days.Described DVR is warned for monitoring site provides background music, broadcast prompting or warning.
(3) client realizes remote mobile by server end and monitors; Described client is directly connected with server or is connected with server end by the Internet or 3G network or wireless network;
Described server end, by Network Capture Remote Acquisitioning AV signal, is realized the remote transmission of AV signal.Client, by access services device, is obtained audio frequency and video, realizes remote mobile monitoring.To realize local and remote monitoring simultaneously.
(4) according to monitoring, judge whether monitored scene exists extremely, if existed extremely, DVR is sent alarm signal, if there is no abnormal, continues monitoring.
Embodiment 2
The present embodiment provides a kind of mobile monitor warning device, comprising: watch-dog 1, electric power system 2, DVR 3, server 4; Described watch-dog 1, DVR 3 and electric power system 2 are located in a mobile tank; Described server is provided with network communication with DVR and is connected.
Described watch-dog 1 comprises video camera 11, pick-up 12, burglar alarm 13, microphone 14, sound equipment 15, described watch-dog obtain and transmission of audio signal and vision signal to DVR; Described video camera 11, pick-up 12, sound equipment 15 are located in removable draw-bar box, can move and obtain Audio and Video.
Described electric power system 2 comprises storage battery 21 and transformer 22, be used to DVR to provide without external power supply power supply or external power supply power supply, transformer 22 has alternating current-direct current bumpless transfer function, built-in large capacity battery, can be under the operational environment without external power supply continuous operation 2-3 days.For example, having in external power supply situation, exchange AC220V external power supply is DVR power supply after direct current DC12V transformer transformation, and to the charging of direct current DC12V storage battery, in without external power supply situation, by direct current DC12V storage battery, is that DVR is powered.
Described DVR 3 comprises input/output module, data memory module, network connecting module, alarm module, broadcast system, global positioning system; Described input/output module is for the input and output of audio frequency and video or alarm signal, and described network connecting module is used for realizing wireless network connection, 3G network connects or the Internet connects, and described alarm module is for the output of alarm signal; Described broadcast system, for the audio frequency that comprises background music, broadcast prompting or warning warning is provided, publicizes, dredges and warn monitoring site; Described global positioning system is for realizing location, monitoring or the navigation of described mobile monitor warning device; Described data memory module has digital video audio coding decoding and adverse circumstances Large Volume Data hard-disc storage function.
The course of work of described mobile monitor warning device is as follows:
1, removable draw-bar box is placed in to monitoring site, uses storage battery or external power supply to power for DVR.
2, start watch-dog, video camera and pick-up obtain live video audio frequency, and AV signal is flowed to DVR, and broadcast system is warned for scene provides background music, broadcast prompting or warning.
3, DVR obtain, parsing, storing audio vision signal, audio and video information is transferred to local monitor and is transferred to server by network system.
