In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, control is illustrated below The specific implementation mode of the present invention.It should be evident that drawings in the following description are only some embodiments of the invention, for For those of ordinary skill in the art, without creative efforts, other are can also be obtained according to these attached drawings Attached drawing, and obtain other embodiments.
To make simplified form, part related to the present invention is only schematically shown in each figure, they are not represented Its practical structures as product.In addition, so that simplified form is easy to understand, there is identical structure or function in some figures Component only symbolically depicts one of those, or has only marked one of those.Herein, "one" is not only indicated " only this ", can also indicate the situation of " more than one ".
According to one embodiment provided by the invention, as shown in Figure 1, a kind of detection method of safety belt, including step:
Whether safety belt male connector and safety belt female on S100 detection seats are in buckling state;
S200 detects safety belt or backrest when detecting that safety belt male connector and safety belt female are in buckling state On signal receiver whether receive the detection signal that signal projector is sent out;The signal projector is arranged in the seat On backrest or safety belt;
When the signal receiver is arranged on the safety belt, the transmitter is arranged on the backrest; When the signal receiver is arranged on backrest, the signal projector is arranged on the safety belt.The letter Number transmitter includes pinger, light wave transmitter;The signal receiver includes acoustic receiver, Lightwave receiver.
S300 detects to be in when the signal receiver does not receive the detection signal that the signal projector is sent out The safety belt of buckling state is located on seat before the body of passenger, and the safety belt on the seat has been fastened;
S400 is detected when the signal receiver receives the detection signal that the signal projector is sent out in button The safety belt of conjunction state is not located on seat before the body of passenger, and the safety belt on the seat is not fastened.
Specifically, passenger sits on seat, whether microprocessor detection safety belt male connector and safety belt female fasten, then examine Passenger is looked into whether in the safety belt in buckling state, is detecting that safety belt is in buckling state and detects on seat Passenger is in safety belt, then microprocessor judges that passenger has fastened seat belts, and otherwise, microprocessor then judges safety belt not It fastens.
For example, passenger is outside safety belt;On the seat, by safety belt fastening, microprocessor detects at safety belt passenger In buckling state, passenger is outside safety belt at this time, then microprocessor judges that the passenger does not fasten seat belts;For another example passenger exists In safety belt, on the seat, by safety belt fastening, microprocessor detects that safety belt is in buckling state to passenger, at this time passenger In safety belt, then microprocessor judges that the passenger has fastened seat belts.
According to another embodiment provided by the invention, as shown in Fig. 2, a kind of detection method of safety belt, including step:
Whether the metal deck in sheet metal and safety belt female on S101 detection seats in safety belt male connector is clamped, and makes Whether the circuit where obtaining the sheet metal, metal deck forms closed circuit;
S102 is when the circuit where the sheet metal and the metal deck forms closed circuit, the peace on the seat Full band male connector and safety belt female are in buckling state;
S103 is not when the circuit where the sheet metal and the metal deck forms closed circuit, on the seat Safety belt male connector and safety belt female are in non-buckling state.
It is provided with the power supply being electrically connected with the sheet metal in the safety belt male connector, is arranged in the safety belt female There are the resistance being electrically connected with the metal deck, the resistance to be also grounded;Or;Be provided in the safety belt female with it is described The power supply of sheet metal electrical connection, is provided with the resistance being electrically connected with the metal deck, the resistance in the safety belt male connector Also it is grounded.
S200 detects safety belt or backrest when detecting that safety belt male connector and safety belt female are in buckling state On signal receiver whether receive the detection signal that signal projector is sent out;The signal projector is arranged in the seat On backrest or safety belt;
When the signal receiver is arranged on the safety belt, the transmitter is arranged on the backrest; When the signal receiver is arranged on backrest, the signal projector is arranged on the safety belt.The letter Number transmitter includes pinger, light wave transmitter;The signal receiver includes acoustic receiver, Lightwave receiver.

When level of the S1013 at the sheet metal or at the metal deck does not change, the safety is detected It is not clamped with the metal deck in the sheet metal and safety belt female in male connector so where the sheet metal, metal deck Circuit forms closed circuit.
S102 is when the circuit where the sheet metal and the metal deck forms closed circuit, the peace on the seat Full band male connector and safety belt female are in buckling state;
S103 is not when the circuit where the sheet metal and the metal deck forms closed circuit, on the seat Safety belt male connector and safety belt female are in non-buckling state.
It is provided with the power supply being electrically connected with the sheet metal in the safety belt male connector, is arranged in the safety belt female There are the resistance being electrically connected with the metal deck, the resistance to be also grounded;Or;Be provided in the safety belt female with it is described The power supply of sheet metal electrical connection, is provided with the resistance being electrically connected with the metal deck, the resistance in the safety belt male connector Also it is grounded.
S200 detects safety belt or backrest when detecting that safety belt male connector and safety belt female are in buckling state On signal receiver whether receive the detection signal that signal projector is sent out;The signal projector is arranged in the seat On backrest or safety belt;
When the signal receiver is arranged on the safety belt, the transmitter is arranged on the backrest; When the signal receiver is arranged on backrest, the signal projector is arranged on the safety belt.The letter Number transmitter includes pinger, light wave transmitter;The signal receiver includes acoustic receiver, Lightwave receiver.
S300 detects to be in when the signal receiver does not receive the detection signal that the signal projector is sent out The safety belt of buckling state is located on seat before the body of passenger, and the safety belt on the seat has been fastened;
S400 is detected when the signal receiver receives the detection signal that the signal projector is sent out in button The safety belt of conjunction state is not located on seat before the body of passenger, and the safety belt on the seat is not fastened.
Specifically, microprocessor is also electrically connected with metal deck in the safety belt male connector inner metal sheets or safety belt female It connects;On the seat, by safety belt fastening, microprocessor detects safety belt male connector inner metal sheets, gold in safety belt female to passenger The circuit that category deck, resistance are constituted has formed a circuit, and microprocessor detects at safety belt male connector inner metal sheets or peace Changed entirely with the level in female at metal deck, determines that passenger is by safety belt fastening at this time;Microprocessor is again Determine that passenger is fastening in the safety belt completed, microprocessor judges that the safety belt of passenger has been fastened at this time.
For another example passenger does not fasten seat belts, passenger is in safety belt;Microprocessor detects metal in safety belt male connector The circuit that metal deck, resistance are constituted in piece, safety belt female detects safety belt public affairs without forming a circuit, microprocessor Level at head inner metal sheets or in safety belt female at metal deck does not change, determines that passenger is without by safety belt at this time It fastens;Microprocessor judges that the safety belt of passenger is not fastened at this time.
