System design of digital front-end equipment trial monitoring command system structure see Figure 2. Install the camera in the interrogation room, interrogation rooms, generally every three cameras were used to ingest suspects, investigators and panoramic picture interrogation room, where suspects and investigators through the PIP overlay image will be two-way video signal synthesis a picture, every interrogation room with Road video signal sent to the audio and video matrix and DVR, in real-time displays in the control room monitoring and archiving information. By installing professional sound pickup pickup interrogation room, and achieve high-fidelity results. Real-time display on the monitor screen, the date, time, temperature and humidity information (temperature and humidity environmental monitors through the interrogation room to get). Front of the control center through audio and video matrix video information transmitted to the TV on the wall, commanding officers can watch the screen and through the interrogation room in front of the interrogators voice guidance to observe the progress of each case. Commanding officers can use Bluetooth headsets and other devices and interrogators in real time voice, text, video exchange, guidance throughout the trial. Compared with other trial monitoring systems, remote interrogation of the digital control system has the following characteristics: 1. High-definition audio and video sync audio and video recording system, an image processing system using the latest technology, video and audio compression card, MPEG4 image compression format, maximum image resolution reach D1, equivalent to DVD quality. And the network bandwidth is very low. Interrogators and the synthetic image regardless of the trial's real-time monitoring or video file playback, dual-screen display can be switched freely. Professional speech processing systems used pickup device, so that the sound capture high sensitivity, low distortion, reached a clear voice, pure and high requirements. (2) real-time backup system discs produced during the trial recording video data is saved to a DVD disc in real time, while the trial edge preservation. The system supports up to four DVD drive while burning, and can be selected according to the number of different interrogation room burning strategies, each strategy has advantages. Strategy One, an interrogation room, a CD-ROM drive strategy, the system supports up to four interrogation room to burn, engraved after the disc is ejected into another late burn again, this approach allows each interrogation room data are handled separately burning, conducive to different data kept separate dossier, this method is applicable to the interrogation room of more. Strategy II, an interrogation room two burners, two burners simultaneously burn, reaching double burn backups. This method is particularly important for data situation. Strategy 3 loop recording, by a plurality of burners on the same information to the interrogation room to burn, the first one finished a late burner carved automatically go to the second burner to burn, followed by cycle, this method is suitable for prolonged interrogation, which eliminates the tedious replacement disc. These burn strategy not only supports the centralized server side to save the data, but also support the end of the trial, investigators may need to backup data interrogation, without going through the server, investigators can choose engraved and not engraved, the investigators provided convenient. 3 Powerful file management system for the trial monitoring system, the integrity of data storage and query statistics crucial dossier management system responsible for managing all information dossier relating to the trial, to facilitate Procuratorate investigators. The system provides a powerful query statistics and backup features, such as: press dossier query, you can find out all about the case with the person questioned and record video information data; using the person's name being questioned as a query, you can check out of all the person's information and record video data, query results can be automatically generated folder and back up to removable hard disk, optical disk and other storage devices, thus facilitating the collation of data and transfer, especially in the remote interrogation time, which greatly facilitates a copy of the dossier information prosecutors. 4 conductor terminal end and interrogation video, text, use of real-time communication capabilities commanding officers commanding the client computer, click into the interrogation room, and on the same screen monitor, monitor real-time video of the room picture and sound. Progress under interrogation, commanding officers and interrogators for voice, text and video chat, real-time issue various commands, adjust interrogation strategy and direction, is conducive to fast break case. 5 suspects authentic signature confirmation feature a full course of the trial, including the trial from beginning to suspect signatures, but generally only during the trial of the suspect's signature in the form of a text file records and preserved, the system not only able to suspect authentic signature in the form of WORD saved to the computer, but also the suspect's authentic to the video image is saved to ensure the integrity of the suspect information, avoids the previous literature preservation easily lost phenomenon. At the end of the trial, the suspect took the authentic pen sign the record, the system will automatically save the suspect's signature to the live video image and generates a "suspect synchronous recording registration form" to record the entire trial processes and suspects authentic, the document is automatically saved to your computer, and supports preview, print, this function so that the entire trial process digitization, full of. 6.GPS time synchronization generally required when the trial record time for the hearing, and the need to maintain temporal consistency, the feature server-centric, all clients and the server time consistent, if the time difference of one second above, when the school system and the server will automatically be consistent, the use of GPS tracking satellites, strict and Beijing reached unanimously. 7 interrogation room environmental monitoring functions during the trial, the need for the entire interrogation room temperature and humidity for real-time detection, and depending on the temperature and humidity of the system will automatically turn on and turn off air conditioning equipment, etc., making the handling environmental control digital and humane.
