Description
Technical field
It a kind of sets the present invention relates to security inspection field more particularly to for checking whether vehicle has concealed the inspection of personnel
Standby and method.
Background technique
To vehicle whether the personnel of concealing check be safety inspection one of content, and generally use microseism at present
Examined effect.The principle of microseism Examined effect is, if vehicle conceals someone, the shake that the heartbeat bring blood flow of people generates
Dynamic signal can be transferred out by the body and vehicle structure of people come.Due to vehicle nobody when the background vibration signal and vehicle that generate
Power level of the vibration signal generated when someone within the scope of certain frequency is strong and weak different, therefore, using being attracted to vehicle
Shock sensor on body or compartment receives the vibration signal of vehicle, then by the vibration signal of actual measurement and preset vibration signal
Threshold value is compared, so that it may judge whether conceal someone in vehicle.
It whether there is in abiotic removable frame for example, United States Patent (USP) US4415979A discloses one kind for checking
There are the method and apparatus of inanimate object, by the vibration signal of first acquisition vehicle, then analyzes the function of acquired vibration signal
Rate is horizontal, and compares with preset threshold value, to judge whether conceal someone in vehicle.For another example United States Patent (USP) US
6873921 B1 disclose a kind of method and apparatus for checking hiding people in vehicle, it first acquires the vibration signal of vehicle, into
Row wavelet transformation simultaneously extracts the signal power within the scope of certain resonance energy, then compares with preset threshold value, to judge vehicle
Inside whether conceal someone.
But in general, related (such as the United States Patent (USP) of the intensity of vehicle vibration signal and the structure of vehicle
Preferred embodiment description in US6370481B1), this makes the vibration signal intensity threshold of different vehicle will be different.Example
Such as, the decision threshold in the decision threshold in United States Patent (USP) US4415979A (MIN.PWR numerical value) and 6873921 B1 of US
(MINIMUM and THRESHOLD numerical value) needs the influence decision threshold from external input, United States Patent (USP) US US6370481B1
Parameter (MASS numerical value) be also required to by keyboard from external manual input.Therefore, existing microseism checks system, such as the U.S.
The Micro Search of the ENSCO company and DF110 of Taiwan Da Hua Internaional, Inc is pre-stored with various vibration letter
Number threshold value, and vibration signal threshold value is rule of thumb selected by operator when checking, to pass through the vibration signal that will be surveyed and institute
The vibration signal threshold value of selection is compared, to improve the accuracy of inspection result as possible.
However, operator is possible to select wrong vibration signal threshold due to various differences such as viewing angle, operation experiences
Value, to cause inspection result mistake.For example, be easy to causeing someone to be mistaken for nobody if large car is falsely dropped into compact car, make
At failing to report；And if compact car is falsely dropped into large car, be easy to cause nobody to be mistaken for someone, cause to report by mistake.
On the other hand, due in microseism checking process vehicle must be in halted state, when someone is concealed at vehicle bottom, he can be with
Body is detached from microseism checking process or half is detached from body construction, so that the vibration signal for generating heartbeat greatly reduces and is
To disappearance, checked with escaping.
