Of course, other scenarios may also be applied.
Referring to fig. 1 to 4, the structure of the sunroof turning control system will be described:
the skylight turnover control system provided by the embodiment of the invention comprises: the main control unit 401, with main control unit 401 electric connection's data acquisition unit 403 and to the skylight turning device that easy ignition set up, wherein, this skylight turning device includes: the skylight locking mechanism 102 and the skylight driving unit 103 are both electrically connected with the main control unit 401, the skylight locking mechanism 102 locks and releases the skylight 101 under the control of the main control unit 401, and the skylight driving unit 103 drives the skylight 101 under the control of the main control unit 401, so that the skylight 101 is turned over under the drive of the skylight driving unit 103; the data acquisition unit 403 acquires ignition data of the ignition prone point and feeds the ignition data back to the main control unit 401, and the data acquisition unit may be connected in a wired or wireless manner, so that the main control unit 401 can control the automatic turning of the skylight 101 according to the ignition data.
In practical implementation, one data acquisition unit 403 and one skylight turnover device may be provided for each ignition prone point, or one data acquisition unit 403 and one skylight turnover device may be provided for a plurality of adjacent ignition prone points, or even a plurality of data acquisition units 403 and a plurality of skylight turnover devices may be provided near one ignition prone point.
It should be noted that the main control unit 401 in the embodiment of the present invention may control the sunroof locking mechanism 102 and the sunroof driving unit 103, which are disposed corresponding to one sunroof 101, only according to the data acquisition unit 403 corresponding to the sunroof 101, so as to control the sunroof 101 to turn over. Referring to fig. 4, the main control unit may also simultaneously control the sunroof locking mechanisms 102 and the sunroof driving units 103, which are disposed corresponding to different skylights 101, according to the data acquisition units 403 corresponding to the multiple skylights 101, so as to simultaneously control the turning of the multiple skylights 101:
in the embodiment of the present invention, the data acquisition unit 403 is configured to acquire ignition data corresponding to an easy ignition point; the main control unit 401 is configured to control the sunroof locking mechanism 102 corresponding to the sunroof turning device to open according to the ignition data fed back by the at least one data acquisition unit 403, and control the sunroof driving unit 103 corresponding to the sunroof turning device to turn the sunroof 101, so that the opening angle of the sunroof 101 faces the ignition point where fire is currently generated.
The main control unit 401 is configured to control the corresponding sunroof driving unit 103, and drive the sunroof 101 to turn in at least one of the following turning manners:
in the first mode, the skylight 101 is fixed after being turned over to a state that the opening angle faces to a current ignition point with fire;
in the second mode, the skylight 101 is turned over in a reciprocating mode within a preset reciprocating angle facing to an easily-ignited point of the current fire; specifically, the frequency of the reciprocal turning is 3 s/time to 8 s/time, and the frequency of the reciprocal turning can be set according to different use requirements, for example, 9 s/time to 18 s/time, 1 s/time to 2 s/time, and the like.
It should be noted that, in an actual situation, the skylight 101 may be turned in any one of the above turning manners, and the skylight 101 may be turned in one turning manner all the time, or two or more turning manners may be provided for each skylight 101 in advance, and the corresponding turning manner is selected according to the difference of the firing data. The multiple turning modes comprise multiple reciprocating turning modes and a first mode with different frequencies, and the two turning modes comprise reciprocating turning and a first mode with single frequency.
In an optional implementation manner, the sunroof turning control system according to an embodiment of the present invention further includes a storage unit (not shown) electrically connected to the main control unit 401 for storing various turning manners preset for each sunroof turning device corresponding to different ignition data.
Specifically, different opening angles and turning modes can be set according to the difference of the distance between the easy ignition point and the easy ignition point where fire occurs:
for example, the turning mode and the opening angle corresponding to each skylight 101 are preset for the easy ignition point a: the opening angle of the skylight 101 facing the easy ignition point A is 60 degrees, the turning mode is a mode one, the opening angle of the skylight 101 away from the easy ignition point A in a first distance range is 45 degrees, the turning mode is a mode one, the opening angle of the skylight 101 away from the easy ignition point A in a second distance range is 45 degrees, the turning mode is a reciprocating turning mode with a reciprocating angle of 10-45 degrees, and the lower limit of the second distance range is larger than or equal to the upper limit of the first distance range. The specific opening angle and the turning mode are only used for reference, and can be set according to actual requirements.
Specifically, different turning modes may be set for each louver 101 in advance according to the difference in fire intensity: for example, the turning manner of each louver 101 is preset to be a reciprocal turning at a reciprocal angle of 10 ° to 45 ° corresponding to the first intensity fire, and the turning manner of each louver 101 is preset to be a first manner corresponding to the second intensity fire. The second intensity fire is greater than the first intensity fire.
Therefore, the turning mode of the skylight 101 can be changed according to the change of the fire intensity to align the fire position with larger fire.
It should be noted that: along with the change of fire intensity, the skylight 101 can be changed from being fixed in an opening angle state to being turned over in a reciprocating mode in a preset reciprocating angle state, and also from being turned over in a reciprocating mode in a preset reciprocating angle state to being fixed in an opening angle state, and each easy ignition point is preset with a corresponding turning mode, and the turning modes are stored in the storage unit, when a fire happens to the easy ignition point, the main control unit 401 can rapidly respond and control the corresponding skylight driving unit 103 to drive the skylight 101 to turn over by reading the turning mode corresponding to the easy ignition point.
As an optional implementation manner, in order to ensure the safety of the skylight 101 during the turning process, the skylight turning control system further includes a distance measuring unit 104 electrically connected to the main control unit 401.
The distance measuring unit 104 is disposed on the skylight 101 and is used for monitoring an actual distance between the skylight 101 and an obstacle. Specifically, the distance measuring unit 104 is fixed to the outer surface or edge of the sunroof 101.
Specifically, the distance measuring unit 104 may be a distance sensor, a hall sensor, or the like. If a distance sensor is adopted, the distance sensor monitors the actual distance between the skylight 101 and the obstacle by measuring the distance between the distance sensor and the obstacle; it should be noted that the distance sensor cannot be disposed near the rotating shaft of the skylight 101 and on the extension line of the rotating shaft of the skylight 101, otherwise the altitude of the ranging unit 104 is not changed significantly or even not changed; if the Hall sensor is adopted, the Hall sensor can be arranged at the rotating shaft of the skylight 101, an angle is formed between the skylight 101 and the support when the skylight 101 is turned over, the potential of the Hall sensor can be changed by the change of the angle, the turning angle of the skylight can be obtained by utilizing the potential change of the Hall sensor, and the actual distance between the skylight 101 and the obstacle can be obtained by calculation.
Although the distance between the frame of the skylight 101 and the obstacle can be monitored by the distance measuring unit 104, for the purpose of protecting the skylight 101 and the obstacle, it is also necessary to control the skylight driving unit 103 to drive the skylight 101 to turn over by the main control unit 401, so that the actual distance between the skylight 101 and the obstacle is greater than the preset safe distance in the process of controlling the skylight driving unit 103 to drive the skylight 101 to turn over, the value of the preset safe distance is related to the installation position of the distance measuring unit 104, and if the distance measuring unit 104 is arranged at the edge far away from the rotating shaft of the skylight 101, the preset safe distance is relatively small. For example, it may be: 5 mm-10 mm, 10 mm-15 mm to guarantee skylight 101 and barrier can not collide each other, avoid causing skylight 101's damage.
As an optional embodiment, the skylight driving unit 103 includes a stepping motor, a rotating shaft of the stepping motor is provided with an anti-slip groove, and the rotating shaft is matched with a damping rubber ring, wherein the stepping motor is in contact with the skylight 101 through the damping rubber ring; the main control unit 401 is specifically configured to control a rotating shaft of the stepping motor to rotate so as to drive the skylight 101 to turn over.
The pivot cooperation has the shock attenuation rubber ring, avoids the motor to produce the noise or skid at the rotation in-process, and skylight drive unit 103 also can be the bigger hydraulic motor of moment of torsion certainly, and a recess can be made to the cross section of its pivot to an inner circle of assembly has corresponding bellied gear, prevents that pivot and gear from skidding, is used for transmitting moment better.
