Quantitative detection device and detection method for spontaneous activity of living body

Abstract

The invention discloses a living body spontaneous activity quantitative detection device which comprises a box body structure with an upper layer and a lower layer, wherein the upper layer is a sensor layer which comprises infrared geminate transistors arranged in a 16*8 matrix, spacing between every two adjacent infrared geminate transistors is 3cm, infrared ray transmitting tubes and infrared ray receiving tubes of the infrared geminate transistors are arranged in parallel, a transparent plate is arranged above the infrared geminate transistors, the lower layer is a control plate layer which comprises a scanning circuit and a control circuit, the scanning circuit and the control circuit are electronically connected, the scanning circuit comprises 18 pieces of CD4051, the control circuit mainly comprises an ATMEGA16 processor chip, the infrared geminate transistors is connected with the scanning circuit through a transmission line, and the control circuit is connected with a display module outside the box body structure. The invention further discloses a detection method with the device used. According to the method, automatic detection of the whole process of the activity of a mouse can be achieved comprehensively and accurately with a simple method, accurate reflection and continuous detection of the process of the activity of the mouse are achieved, and accurate quantitative description of activity in two-dimensional space is achieved.

Description

technical field [0001] The invention relates to a quantitative detection device and detection method for the spontaneous activity of a living body, which realizes positioning, tracking and detection of the whole process of living body activities. For example, the determination of spontaneous behavior in mice. Background technique [0002] At present, the spontaneous activity experiment in vivo belongs to the research category of animal behavior, and has good applications in the research of neurophysiology, safety pharmacology, nutrition and other fields. Animals are affected by drugs, poisons and external factors, whether their nervous system and various activity parameters are affected and changed, which requires the detection of spontaneous activities of animals, and changes in their activity can often evaluate the efficacy of drugs and external influences . In addition, the detection of spontaneous activity behavior is also an important physiological indicator to reflec...

AI Technical Summary

Problems solved by technology

However, computer image and video technology is affected by many factors such as external light source, camera angle and distance, transparency and occlusion, which cause changes in pixel values ​​to cause image changes, thereby affecting the accuracy of recognition and easily causing wrong judgments.

When the living body is partially or completely blocked, detection and analysis cannot be performed

And the application of computer image and video technology equipment is complicated, the cost is high, and it is not easy to operate

Therefore, in order to simply and accurately detect the data of various spontaneous activities of animals, it is still inconvenient to use computer image and video technology.
