Description
Technical field
The present invention relates to automobile technical field, espespecially a kind of detection method and detection device based on safety belt.
Background technology
Safety belt is to ensure a kind of safety device used in safety.Currently, safety belt is all used in automobile mostly,
Or on the vehicles such as aircraft, use also is on the devices such as working at height.
Currently, safety belt on the market is also varied, the conventional method whether detection safety belt is fastened is manually to examine
Survey whether passenger fastens seat belts.However, this safety belt detection mode there are the drawbacks of be:(1) it needs to spend a large amount of people
Power, and it is susceptible to under-enumeration;(2) it can not go out whether safety belt does not fasten completely by visual inspection, if safety belt is not
It fastens completely, safety belt loses its existing meaning.
In recent years, occurs the method whether automatic inspection safety belt is fastened on the market, and this safety belt checks automatically
Method is mainly used on copilot station;When detecting that safety belt does not fasten, prompt tone can be sent out, prompts user security band
In non-buckling state prompt tone is no longer sent out when safety belt is in buckling state.This safety belt automatic check method inspection
It can not check and carry out user whether not in safety belt, such as safety belt has fastened and when user is not in safety belt, it will not
Prompt user fastens seat belts;So in order to realize for the purpose for ensureing safety, safety belt is lost its presence
Meaning.
Therefore, in order to ensure the personal safety of passenger, the problem of the urgent need to resolve equipment safety device this aspect of this field.

It takes;Passenger sits on seat, fastens safety belt, and microprocessor passes through where monitoring safety belt male connector and safety belt female
Whether circuit forms closed circuit, when the circuit where safety belt male connector and safety belt female forms closed circuit, safety
It can occur to change accordingly with the level at male connector and safety belt female, so that it is determined that safety belt has fastened;Microprocessor
When not receiving the signal that the signal projector on backrest is sent out by detecting the signal receiver on safety belt again, determine
Passenger is in safety belt, and microprocessor judges that the safety belt of passenger has been fastened at this time.
For another example in passenger's no longer safety belt, signal projector is mounted on safety belt, and signal receiver is mounted on seat
By back;Passenger sits on the seat, fastens safety belt, and microprocessor detects where safety belt male connector and safety belt female
Circuit when forming closed circuit, the level at safety belt male connector and safety belt female can occur to change accordingly, to really
Determine safety belt to have fastened;Microprocessor receives the signal on backrest by detecting the signal receiver on safety belt again
When the signal that transmitter is sent out, passenger is determined not in safety belt, and microprocessor judges that the safety belt of passenger is not fastened at this time.
