Description
Technical field
The present invention relates to a kind of car of investigating on the spot, refer in particular to the method for investigating on the spot and device thereof that the evidence at the scene information of using a kind of criminal spot is investigated car on the spot.
Background technology
Present criminal usefulness is investigated car on the spot, major function is to carry relevant prospecting equipment with car, in time prospecting is searched in criminal spot, extract necessary material evidence, can not Site Detection to the material evidence that extracts, material evidence detects or will get back to control laboratory carries out, and affects the on-the-spot promptness of judging of explorer.If find in detecting that new problem also will drive up to the spot and collect evidence, this has just affected working quality of case handling and efficient.
In addition, existing Prospecting vehicle mostly is the form of the subsidiary common intense light source of surveying box, and along with the development of science and technology, the latent trace that the suspect stays has the characteristics of diversity, complicacy, the search of common intense light source all can be restricted when being equipped in search and evidence obtaining, especially difficult to the search of latent trace (human eye is poor to the visuality of latent trace), the obvious existing requirement that car can not satisfy site inspection and material evidence technical development of investigating on the spot.
Summary of the invention
The objective of the invention is in order to overcome the problem of prior art existence, provide a kind of scope to the search of criminal spot wide, it is with strong points to collect evidence, can carry out fast full spectrograph to the material evidence that extracts onboard simultaneously, the material evidence information of obtaining is uploaded comparison fast, and gather, pass judgment on by controller, obtain the suspect information relevant with case, and a kind of evidence at the scene information of in time this information being uploaded is investigated the method for investigating on the spot and the device thereof of car on the spot.
An object of the present invention is to be achieved through the following technical solutions:
A kind of evidence at the scene information is investigated the method for investigating on the spot of car on the spot, comprising following steps:
