Public security interrogation room monitoring system

Abstract

The invention relates to the technical field of monitoring systems, in particular to a police interrogation room monitoring system. The system comprises a central machine room and an interrogation room; the interrogation room is internally provided with a front-end monitor, an auxiliary monitor, an interrogation client and a head-mounted device, wherein the auxiliary monitoring device comprises anenvironment monitoring device and a physiology monitoring device, the environment monitoring device comprises a standard clock, a temperature sensor, a humidity sensor and a light intensity sensor, the physiology monitoring device comprises a photoelectric cardiotachometer and an eyeball tracking camera, and the light intensity sensor and the photoelectric cardiotachometer are both arranged in the head-mounted device. According to the invention, indoor environment time, temperature, humidity and illumination intensity are monitored and interrogated through the environment monitoring device, so as to prevent criminal convulsion; moreover, video evidence can be taken out to cope with the criminal convulsion when a suspect turns over, and the heart rate and eyeball movement of the suspect are detected through the physiological monitoring device, the photoelectric cardiotachometer and the eyeball tracking camera, so as to judge whether the suspect lies or not, thereby improving the interrogation efficiency.

[0002] In recent years, the cases of retraction of confessions in duty-related crimes have been on the rise, and many defendants choose to change or retract their confessions during the investigation stage at the trial stage; , causing embarrassment in the court trial and hindering the smooth trial of the case by the judiciary

In addition, some criminal suspects died unexpectedly while they were being held in a detention center or police station, and there was no audio or video material on the spot as evidence afterwards, which aroused strong concern from the society, and also caused serious damage to the image of the public security, procuratorate, court and other judicial departments. negative effect

[0003] Existing interrogation mainly relies on the experience of interrogators in handling cases, which cannot achieve intelligent interrogation, with low interrogation efficiency and high misjudgment rate

In addition, the existing public security interrogation room monitoring system cannot monitor the suspect's physical characteristics and micro-expressions, and it is not easy to break the deadlock in the interrogation, which is not conducive to the development of the interrogation
