As above visible, monitoring camera provided by the utility model not only has for connecting the power supply adaptor interface of external power source, but also there is caulking groove in the battery that can embed battery simultaneously, and preferentially utilize the power supply of power supply adaptor interface to be input as the remaining chip power supply of monitoring camera and transferred to when the power supply input of power supply adaptor interface was lost efficacy and utilize the power supply input of caulking groove in battery to carry out the remaining chip power supply for monitoring camera by a power management chip.Like this, even if there is cracker to cut off in advance all power supplies in the monitoring place at monitoring camera place, also cause thus the external power source that monitoring camera is introduced from the power supply adaptor interface to lose efficacy, monitoring camera also can utilize and be embedded in the power supply input that the battery in caulking groove provides in its battery and realize self-powered and continue to maintain its supervisory function bit with this, thereby the illegal act of cracker in the monitoring place still can be monitored.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
The present embodiment for solve monitoring camera externally power supply by the problem lost efficacy after illegally disconnecting, be not devoted to the precautionary measures how to avoid external power source illegally to be disconnected, but proposed a kind of by the self-powered solution of monitoring camera.
Specifically refer to Fig. 1, at first the monitoring camera in the present embodiment comprises following conventional func parts:
Camera lens 11;
Be arranged in the image sensor chip 12 of the light path of camera lens 11;
Wherein, image sensor chip 12 has sensor array and is electrically connected to sensor array and for generation of the video output terminals of vision signal;
The main control chip 13 be electrically connected to image sensor chip 12;
Wherein, main control chip 13 has the video acquisition end and the video acquisition end is electrically connected to the video output terminals of image sensor chip 12, and main control chip 13 also has the code stream output of the code stream aforementioned Video signal encoding (can adopt H.264, any encryption algorithms such as MPEG4 or MJPEG) obtained for output and for exporting the storage end of aforementioned vision signal;
The net interface controller 14(be electrically connected to main control chip 13 can be wireless lan interfaces control chip and/or wired network interface control chip);
Wherein, net interface controller 14 has the code stream input and the code stream input is electrically connected to the code stream output of main control chip 13, and net interface controller 14 also has for the Internet Transmission end to the aforementioned code stream of Internet Transmission;
The storage chip 15 be electrically connected to main control chip 13; Wherein, storage chip 15 is electrically connected to (can pass through any interface bus such as SPI, SD, USB or SDIO interface bus realizes being electrically connected to) with the storage end of main control chip 13.
Please, again referring to Fig. 1, except above-mentioned conventional func parts, the monitoring camera in the present embodiment also comprises:
Power supply adaptor interface 21;
Caulking groove 22 in battery;
And, with the power management chip 20 that in power supply adaptor interface 21 and battery, caulking groove 22 is electrically connected to.
When power management chip 20 detects power supply adaptor interface 21 power supply input (being that power supply adaptor interface 21 now connects effective external power source) is arranged, no matter whether the interior caulking groove 22 of battery now has power supply input (being now whether to embed the enough batteries of electric weight in caulking groove 22 in battery), power supply input from power supply adaptor interface 21 all can preferentially be carried out voltage transitions and be dispensed to image sensor chip 12 by power management chip 20, main control chip 13, and the conventional func parts such as net interface controller 14 and storage chip 15, to utilize external power source, monitoring camera is realized to power supply,
When power management chip 20 detects power supply adaptor interface 21 non-transformers inputs (being that the effective external power source that power supply adaptor interface 21 connects now is disconnected) but when battery in, caulking groove 22 has power supply input (be in battery in caulking groove 22 now embedding the enough batteries of electric weight are arranged), power supply input from caulking groove in battery 22 is carried out voltage transitions and is dispensed to the conventional func parts such as image sensor chip 12, main control chip 13 and net interface controller 14 and storage chip 15 by power management chip 20, to realize the self-powered of monitoring camera.
And, alternatively, when power management chip 20 detects power supply adaptor interface 21 power supply input (being that power supply adaptor interface 21 now connects effective external power source) is arranged, power supply input from power supply adaptor interface 21 can also further be carried out voltage transitions and be dispensed to caulking groove 22 in battery by power management chip 20, like this, if in battery, caulking groove 22 now embeds battery is arranged, the charging to battery can be realized, to guarantee monitoring camera, the long as far as possible self-powered time can be maintained after switching to self-powered.
In practical application, power supply adaptor interface 21 can further be connected with the power cable with plug, and the battery that in battery, caulking groove 22 is embedded in can the preferred lithium battery.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
