Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] figure 1 It is the curve chart of the temperature drop of the corpse, such as figure 1 Shown: The inference of the early death time is mostly based on the law of the temperature drop of the corpse. The principle is: when the victim just died, the heat energy in the body first conducts to the body surface, and then dissipates from the body...

Abstract

The invention provides a corpse temperature real-time measurement recording analyzer and a death time analysis method. The corpse temperature real-time measurement recording analyzer comprises a hostand at least one temperature probe, the host integrates a processing unit, a storage unit, a display screen and an environment temperature and humidity sensor. A temperature probe is in a round bar shape and is connected to a first signal acquisition end of the processing unit through a signal line. The output end of the environment temperature and humidity sensor is connected to a second signal acquisition end of the processing unit. The display screen is used for displaying the current environment temperature T1, the environment humidity, the corpse temperature T2 obtained by the current temperature probe and the calculated death time X. Compared with the prior art, the method has the advantages that the corpse temperature, the environment temperature and other influence factors are integrated, and the reliable death time is quickly and automatically calculated.

Description

technical field [0001] The invention belongs to the field of corpse temperature measurement and analysis, and in particular relates to a corpse temperature real-time measurement record analyzer and a death time analysis method. Background technique [0002] The time of death, also known as the elapsed time of death (forensic science term), refers to the time elapsed from the death to the forensic examination. The inference of the time of death is the first problem to be solved in forensic identification. The time of death is of great significance to determine the time of the incident, identify and exclude criminal suspects, and delineate the scope of investigation. Especially when the case involves multiple criminal suspects, it is particularly important to accurately determine the time of death. [0003] At present, the commonly used methods for inferring the time of death include: rigor, cadaver spots, degree of corneal opacity, stomach contents, cold corpse and other ind...
