The preferred embodiments of the present application are described in detail as follows, however, the present application can have other embodiments in addition to these detailed descriptions.

[0035] The embodiment provides a traffic vehicle passenger identification system, which is applied to a traffic vehicle and used for identifying a passenger type of a vehicle passenger. Optionally, the traffic vehicle includes a vehicle, an aircraft or a ship, etc. Exemplarily, the passenger type includes a male, a female and a child.

[0036] The embodiment provides a traffic vehicle passenger identification system, which is applied to a traffic vehicle and used for identifying a passenger type of a vehicle passenger. Optionally, the traffic vehicle includes a vehicle, an aircraft or a ship, etc. Exemplarily, the passenger type includes a male, a female and a child. Figs. 1 to 3 As shown in the figure, the traffic vehicle passenger identification system includes: a support structure 1, used for supporting a vehicle passenger; a first pressure sensor component 2, arranged on a front surface of the support structure 1; a second pressure sensor component 3, arranged on a back surface of the support structure 1; and a data processing module 4, connected with the first pressure sensor component 2 and the second pressure sensor component 3, used for outputting a passenger type corresponding to the vehicle passenger when the first pressure sensor component 2 is triggered, or the first pressure sensor component 2 and the second pressure sensor component 3 are triggered.

[0037] As an example, the support structure 1 is used for contacting with the vehicle passenger and supporting the vehicle passenger. Exemplarily, the support structure 1 is arranged on a seat body of the traffic vehicle. Exemplarily, the front surface of the support structure 1 is a surface contacting with the vehicle passenger. The front surface of the support structure 1 is a surface contacting with the seat body of the traffic vehicle.

[0038] As an example, when the vehicle passenger is seated on the seat of the traffic vehicle, the support structure 1 contacts with the vehicle passenger and supports the vehicle passenger, and the first pressure sensor component 2 and the second pressure sensor component 3 detect the pressure of the vehicle passenger on the support structure 1. The first pressure sensor component 2 and the second pressure sensor component 3 have different pressure trigger thresholds respectively. Since the vehicle passengers of different passenger types have different weights, and further have different pressures on the support structure 1. In this example, by arranging the first pressure sensor component 2 on the front surface of the support structure 1 and arranging the second pressure sensor component 3 on the back surface of the support structure 1, the passenger type of the current vehicle passenger can be determined by the first pressure sensor component 2 and the second pressure sensor component 3 with different pressure trigger thresholds. Exemplarily, when the data processing module 4 detects that only the first pressure sensor component 2 is triggered, the passenger type corresponding to the vehicle passenger is output as a female or a child. When the data processing module 4 detects that the first pressure sensor component 2 and the second pressure sensor component 3 are both triggered, the passenger type corresponding to the vehicle passenger is output as a male.

[0039] In the embodiment, the traffic vehicle passenger identification system comprises a support structure 1 for supporting a vehicle passenger, a first pressure sensing assembly 2 arranged on the front of the support structure 1, a second pressure sensing assembly 3 arranged on the back of the support structure 1, and a data processing module 4 connected to the first pressure sensing assembly 2 and the second pressure sensing assembly 3, for outputting a passenger type corresponding to the vehicle passenger when the first pressure sensing assembly 2 is triggered, or the first pressure sensing assembly 2 and the second pressure sensing assembly 3 are triggered. By arranging the first pressure sensing assembly 2 and the second pressure sensing assembly 3 on the front and back of the support structure 1 respectively, the passenger type of the vehicle passenger can be classified according to the triggering conditions of the first pressure sensing assembly 2 and the second pressure sensing assembly 3, and the cost of the traffic vehicle passenger identification system can be reduced while ensuring the classification accuracy.

[0040] In an embodiment, the triggering pressure threshold of the first pressure sensing assembly 2 is smaller than the triggering pressure threshold of the second pressure sensing assembly 3.

[0041] As an example, the triggering pressure threshold of the first pressure sensing assembly 2 is 15 kg, and the triggering pressure threshold of the second pressure sensing assembly 3 is 50 kg.

[0042] When no one sits on the seat of the traffic vehicle, the first pressure sensing assembly 2 is not triggered, and the second pressure sensing assembly 3 is not triggered, and the data processing module 4 receives two signals that no one sits on the seat, and it is determined that no one sits on the seat.

[0043] When a person with light weight sits on the seat of the traffic vehicle, the first pressure sensing assembly 2 is triggered, and the second pressure sensing assembly 3 is not triggered, and the data processing module 4 receives a signal that someone sits on the seat through the first pressure sensing assembly 2, and receives a signal that no one sits on the seat through the first pressure sensing assembly 2, and it is determined that a child or a female sits on the seat.

[0044] When a person with heavy weight sits on the seat, the first pressure sensing assembly 2 is triggered, and the second pressure sensing assembly 3 is also triggered, and the data processing module receives a signal that someone sits on the seat through the first pressure sensing assembly 2, and receives a signal that someone sits on the seat through the second pressure sensing assembly 3, and it is determined that an adult male sits on the seat.

[0045] In the embodiment, the triggering pressure threshold of the first pressure sensing assembly 2 is smaller than the triggering pressure threshold of the second pressure sensing assembly 3, so that the first pressure sensing assembly 2 and the second pressure sensing assembly 3 can detect vehicle passengers with different weights, and the passenger type detection of the vehicle passenger can be realized while ensuring low cost.

[0046] In an embodiment, the projection of the central region of the first pressure sensing assembly 2 in the first direction at least partially overlaps the projection of the central region of the second pressure sensing assembly 3 in the first direction.

[0047] As an example, the first direction is the direction of gravity, or a direction that is preset angle with the direction of gravity. The preset angle can be set according to actual experience, which is not limited here.

[0048] In the embodiment, the projection of the central region of the first pressure sensing assembly 2 in the first direction at least partially overlaps with the projection of the central region of the second pressure sensing assembly 3 in the first direction, so that the first pressure sensing assembly 2 and the second pressure sensing assembly 3 can more accurately identify the pressure applied by the vehicle occupant in the first direction, and improve the accuracy of the vehicle occupant type.

[0049] In an embodiment, the first pressure sensing assembly 2 includes a connecting piece and a plurality of first pressure switch sensors; the connecting piece is arranged on the front surface of the support structure 1, and the connecting piece is provided with a first connecting end, a second connecting end and a series and / or parallel circuit; the first connecting end is used to connect the data processing module 4; the second connecting end is used to ground the series and / or parallel circuit for connecting the first connecting end and the second connecting end; and the plurality of first pressure switch sensors are arranged on the connecting piece and connected with the series and / or parallel circuit.

[0050] As an example, the plurality of first pressure switch sensors are connected with the series and / or parallel circuit. As an example, the plurality of first pressure switch sensors include pressure switches S1 to S6. The pressure switch S1, the pressure switch S3 and the pressure switch S5 are connected in parallel, the pressure switch S2, the pressure switch S4 and the pressure switch S6 are connected in parallel, and the parallel pressure switch S1, the pressure switch S3 and the pressure switch S5 and the parallel pressure switch S2, the pressure switch S4 and the pressure switch S6 are connected in series between the data processing module 4 and the ground. When any one of the pressure switch S1, the pressure switch S3 and the pressure switch S5 is triggered, and any one of the pressure switch S2, the pressure switch S4 and the pressure switch S6 is triggered, the data processing module 4 and the ground are conducted, so that the data processing module 4 judges that the first pressure sensing assembly 2 is triggered. It can be understood that when the pressure on the pressure switches S1 to S6 does not reach the trigger pressure threshold, the resistance of the pressure switches S1 to S6 is greater than 10k ohms, and when the pressure on the pressure switches S1 to S6 reaches the trigger pressure threshold, the resistance of the pressure switches S1 to S6 changes to 0-100 ohms.

[0051] In the embodiment, the first pressure sensing assembly 2 comprises a connecting piece and a plurality of first pressure switch sensors; the connecting piece is arranged on the front surface of the support structure 1, and the connecting piece is provided with a first connecting end, a second connecting end and a series and / or parallel circuit; the first connecting end is used for connecting the data processing module 4; the second connecting end is used for grounding the series and / or parallel circuit for connecting the first connecting end and the second connecting end; the plurality of first pressure switch sensors are arranged on the connecting piece and connected with the series and / or parallel circuit, so that the first pressure sensing assembly 2 can more accurately collect the pressure applied by the vehicle occupant on the support structure 1 by arranging a plurality of first pressure switch sensors.

[0052] Further, the connecting piece can be single type, H type or Wang type to ensure that the first pressure sensing assembly 2 has a suitable detection range.

[0053] In an embodiment, the connecting piece is H-shaped, and the plurality of first pressure switch sensors are arranged on the connecting piece at intervals.

[0054] As an example, the connecting piece is H-shaped to cover the H-point position on the seat of the vehicle, so that the vehicle occupant can be more accurately detected. In this example, the plurality of first pressure switch sensors are arranged on the connecting piece at intervals. For example, the plurality of first pressure switch sensors are uniformly distributed on both sides of the connecting piece, and the first pressure switch sensors on each side are arranged at intervals.

[0055] In the embodiment, the connecting piece is H-shaped, and the plurality of first pressure switch sensors are arranged on the connecting piece at intervals to conform to the human body model and the standard seat posture, so as to ensure the accuracy of detecting the pressure applied by the vehicle occupant on the support structure 1.

[0056] In an embodiment, the back surface of the support structure 1 is provided with a first assembly groove; the second pressure sensing assembly 3 comprises a shell and a second pressure switch sensor; the first side surface of the shell is provided with a fixed connecting part, the second side surface is provided with a third connecting end and a fourth connecting end, the shell is embedded in the first assembly groove, and the shell is connected with the support structure 1 through the fixed connecting part; the third connecting end is used for connecting the data processing module 4, and the fourth connecting end is used for grounding; the second pressure switch sensor is arranged in the shell and connected with the third connecting end and the fourth connecting end.

[0057] For example, the fixed connecting part adopts a sheet metal structure.

[0058] As an example, the second pressure switch sensor includes a pressure switch S7. The pressure switch S7 is arranged in series between the data processing module 4 and the ground. When the pressure switch S7 is triggered, the data processing module 4 and the ground are conducted, so that the data processing module 4 determines that the second pressure sensor assembly 3 is triggered. It can be understood that when the pressure on the pressure switch S7 does not reach the trigger pressure threshold, the resistance of the pressure switch S7 is greater than 10k ohms, and when the pressure on the pressure switch S7 does not reach the trigger pressure threshold, the resistance of the pressure switch S7 changes to 0-100 ohms.

[0059] As an example, when the weight of the vehicle occupant is too large, the pressure applied by the vehicle occupant to the support structure 1 is transmitted to the second pressure switch sensor on the back of the support structure 1 through the support structure 1, and when the pressure is greater than the trigger pressure threshold of the second pressure switch sensor, the pressure switch S7 is conducted, and the resistance of the pressure switch S7 changes to 0-100 ohms, so that the data processing module 4 determines that the second pressure sensor assembly 3 is triggered.

[0060] In this embodiment, the back of the support structure 1 is provided with a first assembly groove; the second pressure sensor assembly 3 includes a housing and a second pressure switch sensor; the first side of the housing is provided with a fixed connection part, the second side is provided with a third connection end and a fourth connection end, the housing is embedded in the first assembly groove, and the third connection end is used for connecting the data processing module 4 and the fourth connection end is used for grounding; the second pressure switch sensor is arranged in the housing and connected with the third connection end and the fourth connection end, which is simple in structure and reduces the cost of the second pressure sensor assembly 3.

[0061] In an embodiment, the housing is made of plastic or silica gel material. In this embodiment, the housing is made of plastic or silica gel material to ensure that the second pressure switch sensor in the second pressure sensor assembly 3 can be accurately triggered.

[0062] In an embodiment, the support structure 1 is made of foaming material. In this embodiment, the support structure 1 is made of foaming material to ensure that the vehicle occupant has a better riding experience, and at the same time has a better force transmission, so as to facilitate the second pressure sensor assembly 3 on the back of the support structure 1 to accurately detect the pressure applied by the vehicle occupant on the support structure 1.

[0063] The embodiment provides a traffic vehicle, which comprises a seat body and the traffic vehicle occupant identification system described above; the support structure 1 is arranged on the seat body.

[0064] In an embodiment, the second pressure sensing assembly 3 on the back of the support structure 1 is arranged opposite to the position of the H point on the seat body. In this embodiment, the second pressure sensing assembly 3 on the back of the support structure 1 is arranged opposite to the position of the H point on the seat body, so as to ensure that the first pressure sensing assembly 2 and the second pressure sensing assembly 3 are located at positions conforming to the human body model and the standard seat sitting posture, and the accuracy of detecting the pressure when the vehicle occupant applies the pressure to the support structure 1 is ensured.

[0065] Exemplarily, according to the position of the H point on the seat body, the first pressure sensing assembly 2 is arranged on the front of the seat foam (support structure 1), so as to ensure that the detection range thereof is +100 mm forward, +20 mm backward, +30 mm left and +30 mm right of the position of the H point. According to the position of the H point on the seat body, the second pressure sensing assembly 3 is arranged on the back of the seat foam (support structure 1) and is fixed by the sheet metal, so as to ensure that the detection range thereof is +100 mm forward, +20 mm backward, +30 mm left and +30 mm right of the position of the H point.
