note: in fig. 1, the solid line connection represents the power supply connection, and the dotted line connection represents the CAN line connection.
Detailed Description
As shown in fig. 1 and 2, the utility model discloses a vehicle detection system that paddles, it includes awakens up module, controller, communication module, external terminal and three detection module of group.
The detection module is used for detecting the water level condition of the current vehicle parking position, and the ultrasonic sensor is selected in the scheme, is not influenced by light factors, and is high in detection speed and high in precision. Three detection modules are respectively arranged at the left rear-view mirror, the right rear-view mirror and the air inlet pipe of the vehicle, so that the detection of the wading condition around the vehicle can be basically realized, and the detection reliability is ensured.
The detection module is connected with the controller through a wire, the detection module is used for taking electricity from a DO end (a digital output end) of the controller, and meanwhile, a signal output end of the detection module is connected with an AI end (an analog input end) of the controller. After the controller is awakened, the detection module is awakened and sends a detection instruction, the detection module immediately carries out primary water level detection, and a detection result is fed back to the controller. In this case, the wake-up means to be powered on or to be switched from a standby state to an operating state.
The communication module, the awakening module and the controller are connected through CAN lines in pairs, and the awakening module is also connected with the communication module and the controller power supply respectively, namely the communication module and the controller take power from the awakening module. The awakening module is connected with a storage battery wire of the vehicle, and can be regarded as a power supply control master brake of the whole system (vehicle-mounted part). The communication module is in wireless communication connection with an external terminal and used for information interaction and receiving of control instructions. Because the external terminal sends the control command with uncertainty, in order to guarantee that the communication module can receive the control command in time, the awakening module continuously calls the communication module to supply power. Certainly, also awaken the module and can awaken communication module regularly, for example awaken communication module once every three minutes at intervals, and communication module awakens the time at every turn and keeps 20 seconds, through the mode of awakening regularly to reduce the loss of electric energy, avoid the battery insufficient voltage of vehicle.
The wake-up module wakes up the controller regularly, or the communication module receives the control signal sent by the external terminal and controls the wake-up module to wake up the controller according to the control signal, the two are compatible, the wake-up is controlled by the communication module to be prior, of course, if the interval between the timed wake-up and the wake-up controlled by the communication module is short, for example, within 10 seconds, the execution can be only executed once by default. The external terminal comprises a user terminal and a car factory server, the user terminal is a mobile phone APP, the user can issue instructions at any time and any place to carry out water level detection and receive water level information, and the user can master the wading condition of the loved car at any time. And the car factory server can carry out analysis and judgment according to weather forecast to assign control command according to extreme weather such as the condition of rainstorm and carry out water level detection, the car factory server can carry out wading control to the vehicle in the maintenance period, in time reminds the car owner, reduces after sale.
And the detection result fed back by the detection module is sent to an external terminal through the controller and the communication module. And after receiving the detection result, the controller calculates to obtain the next automatic wake-up time according to the water level information and sends the wake-up module, and the wake-up module receives the next automatic wake-up time and automatically adjusts the next automatic wake-up time. After confirming that the wakeup module receives the next automatic wakeup time and the external terminal receives the detection result (water level information), the wakeup module drives the controller to sleep to wait for the next wakeup. In this case, sleep means to cut off power or to change from an operating state to a standby state.
The adjustment of the auto-wake-up time can be referred to as follows:
detecting water level of 0-15cm, and automatically waking up for 5min;
detecting the water level to be 16-30cm, and automatically waking up for 2min next time;
detecting the water level to be 31-60cm, and automatically waking up for the next time to be 50s;
the detection water level is 61-80cm, and the next automatic wake-up time is 30s.
The utility model discloses a key lies in, awakens up the controller through awakening up the control signal that the module initiative was regularly awaken up the controller or was received external terminal passively, and the controller awakens up the water level condition that back control detection module detected current vehicle to give external terminal with water level information feedback, the user can guarantee the safety of vehicle to the wading condition real time monitoring of vehicle. The wake-up module is used as a power supply brake of the whole system, functional parts except the wake-up module can sleep in a non-detection time period, so that the electric loss of the whole system is very low, and the condition that the vehicle cannot be started due to power shortage is guaranteed. In addition, the controller can set the next automatic wake-up time according to the water level information, adjust the period of water level detection according to the real-time wading condition of the vehicle, avoid careless mistakes caused by fixing the detection period under extreme conditions, and have strong reliability of wading detection.
The above description is only an embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
