The concept of Chemical Subsystem of the Innovative System for Detecting Hidden People in Transport (CHS-ISDHPT) is one of three subsystems of the Mobile Operating Platform (MOP-ISDHPT). The MOP-ISDHPT will be used to increase the detection of illegal smuggling of people. The chemical subsystem will consist of: a transport platform, a sample conditioning system, a gas chromatograph coupled with an ion-mobility spectrometer (GC-IMS), and a data integrator. Two concepts of CHS-ISDHPT development are considered, differing in the location of the GC-IMS installation. Apart from the location of the GC-IMS, both concepts differ in the method of measurement, ease of use, detection limit, and exposure of the analytical equipment to environmental conditions.
The concept of the Innovative System for Detecting Hidden People in Transport (ISDHPT) is an attempt to create an innovative platform to increase the detection of illegal smuggling of people and unauthorized objects. For this purpose, various types of detectors will be integrated into the system: based on measurements in the terahertz band, the X-ray radiation band, and using a set of various chemical sensors. The proposed solution is a world-first that includes the fusion of data from terahertz cameras operating in different bands and different imaging modes, a set of different chemical sensors, and X-ray back-scatter sensors. The system will be used when carrying out checks on means of transport to detect people trying to cross the state border illegally. It is assumed that the system's implementation will improve the level of public safety by increasing the effectiveness of actions taken in the area of transport means control.
