Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Present embodiments provide the intelligent alarm system that a kind of analog video camera and DVR form, intelligent alarm system comprises analog video camera and DVR, wherein, analog video camera can be connected with DVR is long-range by circuit, DVR and DigitalVideoRecorder(DVR).
And, as shown in Figure 1, the camera lens of analog video camera is fixedly installed image sensor, photoresistance and pir sensor, pir sensor and human body infrared acquisition sensor, analog video camera inside is also provided with mainboard and the main process chip of the ISP for superposing intelligent signal, wherein, pir sensor is directly connected with mainboard, and be connected with the main process chip of ISP by mainboard, the main process chip of ISP is also connected with imageing sensor, the image information that imageing sensor collection is taken also sends to the main process chip of ISP, the main process core of ISP is for being provided with image processing engine module, cmos image sensor interface, TV scrambler, the main process chip of ISP of D/A converter.
Such as: main process chip can adopt high-performance CMOS image signal processing chip NVP2431H to be ISP, the connecting circuit figure of NVP2431H chip as shown in Figure 2, the powerful image processing engine of NVP2431H built-in chip type, cmos image sensor interface, TV scrambler, D/A converter, provides NTSC/PAL video frequency output, have low in energy consumption, resolution is high, flexible configuration, customization degree high.U.S. person of outstanding talent prestige (OV) company CIS (CMOS Image Sensor) OV9712 1/4 imageing sensor of the ultralow photograph of configuration high-performance.Image, picture valid pixel can reach 1280x720P.Further, main process chip provides clock frequency by FLASH/EEPRO/ crystal oscillator.
Further, main process chip is also connected with DVR, and the signal sent by receiving the main process chip of ISP judges the duty of current pir sensor, and by the display of DVR, the intelligent alarm realized containing picture pushes, Automated condtrol and intelligent monitoring.
Its principle of work is: as shown in Figure 2, the monitoring simulation camera 101 of human body infrared induction is housed operationally, when detecting human body infrared induction by photoresistance 103, the human mobile signal sensed can be coupled in digital intelligent integrated circuit (IC) chip by very high-impedance differential input circuit by pir sensor 102, signal is changed into ADC digital signal by digital intelligent integrated circuit, the REL level just having time delay when PIR signal exceedes selected digital threshold values exports, pass through processing of circuit, be given on a GPIO interface that the main process chip of ISP defined, by the software operation of inside, an intelligent signal can be superposed in the video output signals of the main process chip of ISP, wherein, intelligent signal can be various alerting signal, such as, dialog box alarm indication, or sound alert ring intelligent signal etc., and by Signal transmissions to the DVR of rear end, DVR judges the duty of current PIR by the signal received, by being superimposed upon the intelligent signal on video output signals, the intelligent alarm realized containing picture pushes, Automated condtrol and intelligent monitoring, greatly improve the power resolving ability of infrared alarm, also be that the use of traditional security protection camera is reformed simultaneously.
