Embodiment 1

[0018] Such as figure 1 As shown, the night vision monitoring system without red light of the present invention includes a lens, and the lens adopts infrared diode illumination with a central wavelength of 940nm to collect reflected light from the subject and emit it in the CCD chip module; the CCD chip module is based on the intensity of light. The corresponding charge is weakly accumulated, and after periodic discharge, an electrical signal is generated and sent to the pre-intermediate discharge circuit. The pre-intermediate discharge circuit receives the electrical signal and controls the gain of the AGC module, and sends it to the digital information good DSP module. The DSP module The clock signal is generated by the crystal oscillator circuit, and then the image is processed by DSP and sent to the controller. When working: the central wavelength of the infrared diode used for night vision is 940nm, which is invisible to the human eye.

Embodiment 2

[0020] Such as figure 1 As shown, the night vision monitoring system without red light of the present invention includes a lens, and the lens adopts infrared diode illumination with a central wavelength of 940nm to collect reflected light from the subject and emit it in the CCD chip module; the CCD chip module is based on the intensity of light. The corresponding charge is weakly accumulated, and after periodic discharge, an electrical signal is generated and sent to the pre-intermediate discharge circuit. The pre-intermediate discharge circuit receives the electrical signal and controls the gain of the AGC module, and sends it to the digital information good DSP module. The DSP module The clock signal is generated by the crystal oscillator circuit, and then the image is processed by DSP and sent to the controller. The controller is a single-chip microcomputer controller. The CCD chip module includes a linear array CCD, a three-line array CCD, an area array CCD and an interle...

Abstract

The invention discloses a night monitor system without red light. The night monitor system without red light comprises a camera, wherein the camera adopts an infrared diode with a center wavelength of940nm for illumination, collects light reflected by a shot object and emits the light onto a CCD chip module; the CCD chip module accumulates corresponding charge according to strength of the light,discharges periodically so as to generate an electric signal and sends the electric signal to an IFAMP, the IFAMP receives the electric signal and sends the electric signal to a DSP module through anAGC module, the DSP module generates a clock signal through a crystal oscillator, the DSP performs image processing, and then the signal is sent to a controller. The controller is a single-chip microcomputer controller, the CCD chip module comprises a linear array CCD, a three-line CCD, an area array CCD and an interweaving transmission CCD. Sensors used by the camera comprise a CCD and a CMOS. The infrared diode for night monitor has the center wavelength of 940nm and the light of the infrared diode cannot be seen by human, and the signal is amplified by the IFAMP and is controlled by the AGCmodule.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a night vision monitoring system without red light. Background technique [0002] The full name of anti-theft door is "anti-theft safety door". It has both anti-theft and safety performance. According to the "General Technical Conditions for Anti-theft Safety Doors", a qualified anti-theft door cannot be pried open by ordinary hand tools such as chisels, screwdrivers, crowbars, and portable electric tools such as electric hand drills within 15 minutes or a 615 square millimeter hole can be opened on the door leaf. opening, or a 38 mm2 opening within a semicircle of 150 mm2 at the locking point. And the lock used on the security door must be the special lock for the security door with anti-drilling function after passing the test by the Testing Center of the Ministry of Public Security. Anti-theft doors can be made of different materials, but only those doors that have passed the standard...
