Principle and characteristics of system technology

1. Technical principle

When someone is hiding inside the vehicle, the heartbeat will vibrate and transmit to the outside of the vehicle. There is a fixed mode of vibration signal brought by human heartbeat, and its frequency is concentrated in a narrow frequency range. By using the vibration signal sensor with high sensitivity, the signal of this frequency can be identified and extracted, and the algorithm of signal processing and pattern recognition can be used to determine whether there are people inside the vehicle.

2. Technical characteristics

The inspection speed is fast, and the shortest inspection time is 15 seconds; the cabinet type overall shape is convenient for rapid movement and deployment at any time; it detects the vibration signal of human heartbeat and passive detection, which is completely harmless to personnel and equipment;

3. System structure and function

It is mainly composed of industrial control computer, signal acquisition and conditioning module, vehicle vibration sensor, ground environment sensor, wind environment sensor, industrial touch screen and mainframe frame.

4.System specific software interface

The main interface of system entry interface system special software consists of functional module area, signal acquisition dynamic display area, inspection result dynamic display area and inspection result final display area. It can display the current login user, the currently selected vehicle model, the currently collected signal waveform and the final result of inspection.

4.Vehicle inspection function

A standard process vehicle inspection can be realized by pressing one key only. The results of simple operation inspection will be displayed on the system interface immediately after the inspection is completed, accompanied by sound and light alarm or prompt for safety release corresponding green alarm light, intermittent sound alarm bell corresponding red alarm light, continuous sound alarm bell vehicles need safety inspection

4.Inspection record management function

Each inspection record is automatically stored in the system database;

The inspection time, operators, inspection results and additional information of all inspection records can be consulted;

The user can specify the time range for retrieving records;

The user can specify the operator to retrieve the record; the user can specify the inspection result (release or search) to retrieve the record.

4.User management function

According to different permissions, users are divided into administrator group and operator group

The administrator group has all permissions; the operator group can only perform normal scanning and inspection

The status of the system configuration user that cannot be changed can be divided into two types: activation and shutdown. The activated user can log in to the system,

Closed users cannot log in and use the system

Administrators can add, change, and delete users

Administrators can change the permissions and status of users

4.System configuration management function

When the system starts a check without complete information input, it can give a warning to the user. This function can be turned on or off by the administrator. It can turn on or off the system's release prompt tone and search alarm tone. The administrator can independently enable or disable any vehicle vibration sensor, ground environment sensor or wind environment sensor.

4.Vehicle calibration management function

The adminisrator can add, change or delete user-defined models for new special vehicles. For user-defined models, vehicle calibration can be carried out. The system automatically collects data and analyzes the standard process of comprehensively forming vehicle information calibration models for no more than 2 minutes (except for the time prepared manually).
