Principle and Application of SZMID-VSCS Prison Special Vehicle Security System

The SZMID-VSCS Prison Special Vehicle Inspection System ( Microseismic Life Detector ) produced by Beijing Shenzhou Mingda High-tech Co., Ltd. is based on the important directives issued by the Ministry of Justice such as “Strengthened by Science and Technology” and “ Policing Force by Science and Technology” to make full use of existing High-tech means to strengthen the construction of security technology prevention systems or equipment in the prison supervision system.

SZMID-VSCS micro - seismic life detector is a patented technology product developed by Beijing Shenzhou Mingda High-tech Co., Ltd. independently. It consists of IPC, control panel, touch screen, cabinet, cable shaft, air conditioner, sensor and data cable. Whether it is a small car, a truck full of goods, or a large trailer, as long as 4 sensors are placed on the cross beam of the vehicle, it can be determined whether there is a person in the vehicle or in the cargo, and it is not necessary to unload the cargo to perform a full vehicle inspection. The system detects and analyzes the rhythmic heartbeat vibration transmitted by the measured object through the sensor, and only takes 8 to 40 seconds to judge whether the vehicle can be released or requires further search.

When someone hides inside the vehicle, the stasher's heart will have a rhythmic beating. This vibration will be transmitted to the suspension of the vehicle, the bottom of the carriage, etc. The vibration will be collected and passed through the data line by connecting the sensor and the vehicle under test. The cable is passed back to the data analysis equipment and analyzed by the analysis software. The range of analysis software operation is precisely concentrated in the frequency range of the heart beat. Based on this vibration analysis, it can be clearly displayed on the display terminal whether or not there is a person, and accompany sound alarm.

At present, the system has been widely used in prisons, docks and border ports in the countries of the Americas, Europe and other countries.
