Detailed Description
The following detailed description of specific embodiments of the invention refers to the accompanying drawings.
Referring to fig. 1-2, it can be seen from the drawings that the active detection system for vehicle water inflow of the present invention comprises a vehicle window controller 2 and a vehicle control unit, and is characterized in that: the automobile water inlet sensor is characterized by further comprising a water sensor 1 arranged on the automobile, wherein the arrangement position of the water sensor 1 on the automobile is lower than that of the automobile window controller 2 so as to sense external water inlet, and the water sensor 1 is electrically connected with the automobile window controller 2 so as to transmit the detected water inlet information to the automobile window controller 2; the vehicle window controller and the vehicle control unit are connected in a bidirectional mode to send water inlet information to the vehicle control unit, the vehicle control unit controls the vehicle window controller to close the vehicle window after receiving the water inlet information, and control of the vehicle window controller on the vehicle window is immediately cut off after the vehicle window is closed.
In practical design, as shown in fig. 2, the water sensor 1 is buried between the floor metal plate 3 and the carpet in the vehicle, and the position of the water sensor 1 can be adjusted without being affected by the arrangement position of the window controller 2, and the water sensor 1 is slightly lower than the window controller 2 as a whole.
Fig. 3 is a schematic diagram of the operating circuit of the water sensor of the present invention.
In order to facilitate a user to know the abnormal condition of the vehicle in time, the vehicle control unit is connected with a specified receiving terminal (a user mobile phone) through the cloud service terminal so as to send prompt information to the specified receiving terminal through the cloud service terminal.
The present invention also provides a method for actively detecting water ingress in a vehicle, as follows, with simultaneous reference to figure 4,
1) embedding a water sensor between a floor metal plate and a carpet in a vehicle in advance, wherein the water sensor is connected with a vehicle window controller, and the vehicle window controller is connected with a vehicle control unit;
2) when a detection circuit between the water sensor and the vehicle window sensor is conducted, the water sensor is indicated to be in water inflow position, the vehicle window sensor knows that the vehicle is in water inflow, and the vehicle window controller sends the vehicle water inflow to the vehicle control unit in a signal mode;
3) the vehicle control unit judges whether the vehicle window is closed, if the vehicle window is not closed, the vehicle window is closed through the vehicle window controller, and the control of the vehicle window controller on the vehicle window is immediately cut off after the vehicle window is closed; if the window is closed, the control of the window by the window controller is directly cut off.
And 3) when the vehicle control unit cuts off the control of the vehicle window controller on the vehicle window, the water inlet information of the vehicle is sent to a specified receiving terminal, and the receiving terminal is usually a mobile phone of a user, so that the user can directly receive active prompts such as a short message and an APP (application), and the water inlet condition of the vehicle can be immediately processed.
Specifically, the information of the vehicle water intake is sent to the designated receiving terminal through a cloud end to a receiving terminal APP or through a short message to the receiving terminal.
The vehicle window controller (or the vehicle body controller) is arranged between a floor metal plate and a carpet in a vehicle, the vehicle window controller is provided with the water sensor, and the arrangement position of the water sensor is about 10mm lower than that of the vehicle window controller in the implementation design. When the water sensor detects that water enters, a circuit (a water detection circuit) shown by a dotted line in fig. 2 is conducted, the circuit voltage of the window controller 2 changes, and the vehicle is judged to enter water and a signal is fed back to the vehicle control unit 4. At this time, the whole vehicle software logic judges that the vehicle window is not allowed to descend (but the physical switch for operating the vehicle window can descend), and if the vehicle window is opened, the vehicle window needs to be closed through the vehicle window controller. And after the window is closed, the control of the window by the window controller is cut off. Simultaneously, through vehicle control unit, the condition that will the vehicle intake at this moment sends user's cell-phone APP or reminds the user through the cell-phone SMS through the high in the clouds to the user can in time know the situation and in time take measures.
Finally, it should be noted that the above-mentioned examples of the present invention are only examples for illustrating the present invention, and are not intended to limit the embodiments of the present invention.
