It is worth mentioning that there are different ways of detecting the number of passengers for different public transportation means, for example, for a subway line, the number of passengers on the same route can be determined according to the number of passengers arriving at the station and the number of passengers leaving the station. Therefore, for the metro vehicle, the extension or retraction of the seat on the metro vehicle can be controlled according to the passenger flow volume of the route to which the metro vehicle belongs, and in this case, the predetermined information can be sent to the electric control driving device by the server in the traffic system according to the passenger flow volume. The embodiments of the present disclosure do not list all possible implementations, and other implementations that can be conceived by one of ordinary skill in the art according to the contents of the embodiments of the present disclosure are within the protection scope of the present disclosure.
The manual control mode and the automatic control mode of the telescopic device 12 are respectively described above. In particular, the two modes can be combined to implement. For example, in the case that the telescopic device 12 includes an electronic control driving module and a second telescopic assembly connected between the seat 10 and the seat accommodating chamber 11, the telescopic device 12 may further include a second operating portion, which is configured to generate an electrical signal by manual operation so as to trigger the electronic control driving module to generate a driving instruction for driving the second telescopic assembly to perform a telescopic action. And a mapping relation exists between each electric signal generated by the second operation part and each driving instruction generated by the electronic control driving module, namely different manual operations can generate different driving instructions.
For example, the second operation portion may be a button for being pressed by a passenger, and when the button is pressed, a high level signal is generated for triggering the electric control driving module to generate and drive the second telescopic rod to retract the seat to the storage position, and when the button is reset, a low level signal is generated for triggering the electric control driving module to generate and drive the second telescopic rod to extend the seat 10 to the extending position.
As still another example, the second operation portion may be, for example, a knob for the passenger to rotate. In a specific embodiment, the rotation amount of the knob with respect to the initial position is positively correlated with the protruding amount of the retractor 12, and for example, when the rotation amount is zero, the protruding amount of the retractor 12 is also zero (corresponding to a state where the seat 10 is completely retracted into the seat storage cavity 11, that is, the storage position of the seat 10). In this case, the occupant can manually control the retraction and extension of the seat 10, and can flexibly adjust the height at which the seat 10 is extended.
Here, the button or knob may be provided on the seat 10, for example, the seat back 102 of the seat 10, or may be provided on the vehicle body, corresponding to the seat 10.
The disclosed embodiment also provides a method for a seat lifting system, which can be applied to the seat lifting system, as shown in fig. 4, and the method includes:
s41, in response to a first event that the number of vehicle occupants is greater than a preset occupant count threshold, controlling the telescoping device 12 to retract the seat 10 to the stowed position such that the seat 10 is located within the seat-stowing cavity 11 to expand the occupant space within the vehicle;
s42, in response to a second event that the number of vehicle occupants is less than or equal to the preset occupant count threshold, controlling the telescoping device 12 to extend the seat 10 out of the seat cavity 11 to the extended position.
By adopting the method, the seat 10 is retracted into the seat accommodating cavity 11, the space of passengers in the vehicle can be enlarged for more passengers to stand, the vehicle transportation capacity is increased, the crowding is relieved, the seat 10 extends out of the seat accommodating cavity 11 for the passengers to take, the taking experience of the passengers can be guaranteed, and therefore the taking experience of the passengers and the relief of the crowding degree of public transport means are effectively considered.
Specifically, in one possible implementation, the seat 10 may include a seat bottom 101 and a seat back 102, and the seat back 102 may be secured to a vehicle body, such as a sidewall of the vehicle body. In this case, the extending and retracting of the seat 10 referred to in steps S41 and S42 specifically means extending and retracting the seat bottom 101, that is, the seat back 102 is always kept at the side wall of the vehicle, so that when the seat bottom 101 is retracted into the seat accommodating chamber 11, the seat back 102 can still serve as an armrest to assist the passenger to stand up, ensuring that the passenger can safely use the passenger space enlarged by the seat bottom 101 being retracted into the seat accommodating chamber 11.
In another possible implementation, the seat lifting system may further include a cover plate 14, where the cover plate 14 is used to close or expose the open end of the seat receiving cavity 11, in which case the method further includes: when information indicating that the seat 10 is located in the seat accommodating chamber 11 is acquired, driving the cover plate 14 to close the open end of the seat accommodating chamber 11; and when information indicating that the seat 10 needs to be extended out of the seat accommodating chamber 11 by the retractor 12 is acquired, the cover plate 14 is driven to expose the open end of the seat accommodating chamber 11.
Further, the first event comprises one or more of acquiring first information representing that the number of passengers riding the vehicle is greater than a preset threshold value and acquiring third information representing that the current time is in a preset passenger flow peak time period;
the second event comprises one or more of the acquisition of second information representing that the number of passengers boarding the vehicle is smaller than the preset threshold value and the acquisition of fourth information representing that the current time is in a preset passenger flow volume low peak time period.
The peak time period and the low peak time period of the passenger flow can be determined according to historical traffic information of the vehicle, and the historical traffic information comprises the number of passengers of the vehicle in a plurality of historical time periods. It is therefore possible to take as the peak passenger flow time period the future time period contemporaneous with the historical time period in which the number of passengers is greater than the preset passenger volume threshold value, and to take as the low passenger flow time period the future time period contemporaneous with the historical time period in which the number of passengers is less than or equal to the preset passenger volume threshold value.
Further, the method further comprises: detecting the number of passengers riding the vehicle to determine whether the first preset event or the second preset event occurs by:
detecting the bearing weight of the vehicle, and determining the number of passengers riding the vehicle according to the bearing weight; and/or the presence of a gas in the gas,
and carrying out portrait recognition on the picture of the interior of the vehicle shot by the camera so as to obtain the number of passengers riding on the vehicle.
It is worth mentioning that the detection of the number of passengers may be specifically performed by the electrically controlled driving device in the seat lifting system. Moreover, for different public transport means, different modes for detecting the number of passengers can be provided, for example, for a subway line, the passenger volume on the same route can be determined according to the number of passengers entering the subway line and the number of passengers leaving the subway line, so that for a subway vehicle, the extension or retraction of the seats on the subway vehicle can be controlled according to the passenger volume of the route to which the subway vehicle belongs.
