Abstract

The invention relates to the technical field of physical evidence investigation and extraction devices, and particularly relates to an intelligent field investigation device. The device comprises an industrial tablet computer, wherein the industrial tablet computer is connected with a zero-distortion CCD and a high-pass ultraviolet CCD, a change-over switch is arranged between the zero-distortionCCD and the high-pass ultraviolet CCD and the industrial tablet computer, a first light source is arranged on the zero-distortion CCD, and a second light source is arranged on the high-pass ultraviolet CCD. According to the scheme of the invention, by replacing different light sources on different CCDs, the purpose of investigating and extracting different types of physical evidences can be achieved, the disadvantages that a large number of field investigation equipment exists, each equipment has poor compatibility, and the like can be well solved, and the device has the functions of acquiringfield base station information and other basic information, rapidly producing an investigation record in the field, carrying out rapid on-site mapping and rapidly making a roll at the scene of a case.

Description

technical field [0001] The invention relates to the technical field of physical evidence investigation and extraction devices, in particular to an intelligent on-site investigation device. Background technique [0002] At present, in the field of on-site investigation of criminal technical cases, different equipment needs to be carried to find and extract different physical evidence. Each equipment is independent and has poor compatibility. A case scene needs to carry several or even a dozen equipment to the scene. There are many equipments, which seriously affects the investigation. efficiency. For example: the discovery of on-site fingerprints requires a UV camera system, the discovery of on-site biological evidence requires a biological evidence discovery instrument, a bloodstain discovery instrument, etc., and the on-site footprint discovery requires a directional reflection camera device, etc. Carry fast copy of hard disk, etc., and infrared camera system / ink sequenc...
