Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a garage door opener based on distance sensing, which includes a signal transmitting device 1 disposed on a vehicle, where the signal transmitting device 1 includes a first signal transmitting device 101 and a second signal transmitting device 102, and the first signal transmitting device 101 and the second signal transmitting device 102 are respectively in communication connection with a mobile terminal 2 of a user and a signal receiving device 3 disposed at a garage door, where when the first signal transmitting device 101 and the second signal transmitting device 102 are in a wake-up state, the first signal transmitting device 101 transmits a wake-up signal to the signal receiving device 3, so that the signal receiving device 3 is woken up when a distance between the first signal transmitting device 101 and the signal receiving device 3 is less than or equal to a preset first distance D1, and when a distance between the second signal transmitting device 102 and the signal receiving device 3 is less than or equal to a preset second distance D2, triggering the signal receiving device 3 to send a garage door opening signal to the controller 4 for controlling the garage door to open the garage door, wherein the preset first distance D1 is the maximum communication distance between the first signal sending device 101 and the signal receiving device 3, the preset second distance D2 is the maximum communication distance between the second signal sending device 102 and the signal receiving device 3, D1 is much greater than D2, for example, D1 k D2 k >1, and preferably k has a value ranging from 5 to 15, for example, 10.
In the embodiment of the present invention, the automatic opening of the garage door may be achieved through information interaction between the signal transmission device 1 and the mobile terminal 2 and between the signal transmission device 1 and the signal reception device 3.
Specifically, in the embodiment of the present invention, the signal transmission apparatus 1 may determine whether or not it is in the sleep state based on the distance from the mobile terminal 2. Specifically, a specific APP may be set on the mobile terminal 2, and the signal strength between the signal transmission device 1 and the mobile terminal 2 is monitored at preset time intervals T1, so as to obtain whether the relative distance between the two is within a certain range. In an exemplary embodiment of the present invention, when the distance between the first signal sending device and the mobile terminal is less than the preset third distance D3, that is, the first signal sending device 101 can receive the signal sent by the mobile terminal 2 or the strength of the signal sent by the mobile terminal 2 exceeds a certain threshold, the first signal sending device 101 is awakened by the mobile terminal 2. On the contrary, if the distance between the first signal transmitting device 101 and the mobile terminal 2 exceeds the preset third distance D3, the first signal transmitting device 101 cannot receive the signal of the mobile terminal 2, or the received signal strength is lower than a certain threshold, and enters the sleep state. In another exemplary embodiment of the present invention, the first signal transmitting device 101 is awakened by the second signal transmitting device 102, wherein when the distance between the second signal transmitting device 102 and the mobile terminal is less than a preset fourth distance D4 (preferably, the fourth distance D4 and the second distance D2 are the same and are both distances at which the second signal transmitting device 102 can be triggered), for example, the mobile terminal can monitor the information of the second signal transmitting device 102, that is, the transmitted signal can be received by the second signal transmitting device 102, and the second signal transmitting device 102 returns a response signal, and the second signal transmitting device 102 is awakened by the mobile terminal 2 and the first signal transmitting device 101 is awakened after the awakening. In the embodiment of the present invention, the first signal transmitting device 101 may be an on-board sensor, and the second signal transmitting device 102 may be a passive RFID. The signal sending device 1 can be powered by the vehicle and/or the battery, and when the power supply mode is the vehicle power supply and the battery is powered, if the vehicle power supply stops and the vehicle can receive the signal of the mobile terminal, the signal sending device sends out the prompt sound of 'do not forget to carry the mobile phone' or the like.
Furthermore, in the embodiment of the present invention, when the first signal transmitting apparatus 101 in the wake-up state cannot communicate with the mobile terminal for a plurality of consecutive preset time intervals T1 (for example, 5), the first signal transmitting apparatus 101 enters the sleep state.
Further, in the embodiment of the present invention, the signal receiving device 3 may be a gated inductor of an RFID. When the first signal transmission device 101 is in the wake-up state (in this case, the second signal transmission device 102 is also in the wake-up state), the broadcast message is a broadcast wake-up signal. In the cache of the vehicle-mounted sensor of the first signal transmission device 101, gating identification information GID1,2, 3.. to.. K, which characterizes a unique identification of the identity of the signal reception device 3, of a plurality of signal reception devices that can be associated with the signal transmission device is stored. The gating identifiers of K signal receiving apparatuses are included in the broadcast message at the same time, i.e. the wake-up signal transmitted by the first signal transmitting apparatus 101 includes a unique identifier CID1 characterizing the identity of the first signal transmitting apparatus and a plurality of gating identifiers GID1,2, 3. In an exemplary embodiment, K is 2, that is, 2 gating identifiers are stored in the buffer of the first signal transmission device 101, including the gating identifiers of the home garage and the office garage. After receiving the broadcast message, a certain signal receiving device checks that its own gating identifier is in a plurality of gating identifiers, and switches from a sleep state to an awake state. When a signal receiving device monitors that a distance between the first signal transmitting device and itself (for example, the distance is determined by monitoring the signal strength of any signal transmitting device in the prior art) is less than or equal to a preset first distance D1, the signal receiving device is awakened by an awakening signal transmitted by the first signal transmitting device 101, specifically, when receiving the awakening signal, the signal receiving device checks whether a signal source is the first signal transmitting device, and if so, switches a sleep state to an awakening state; then, a corresponding response signal is sent to the first signal device, which indicates that the corresponding signal receiving device has been awakened.
In the embodiment of the present invention, the signal receiving device after being woken up monitors the signal strength of the first signal transmitting device 101, i.e., the vehicle-mounted sensor, and the signal of the second signal transmitting device 102, i.e., the passive RFID, at preset time intervals T2. In one example, if the signals transmitted by the first transmitting device 101 and the second transmitting device 102 are simultaneously received by the signal receiving device 3 within a preset short time interval, i.e., a very small time interval within an industrial error, that is, the signals transmitted by the first transmitting device 101 and the second transmitting device 102 are received by the signal receiving device 3, the controller 4 controlling the garage door transmits a garage door opening signal.
In another example, if the signal transmitted from the first transmitting device 101 received by the signal receiving device 3 is gradually increased and the signal transmitted from the second transmitting device 102 is received again within the preset time interval t, the garage door opening signal is transmitted to the controller 4 for controlling the garage door. Preferably, t is a (D1'-D2')/V, where D1 'and D2' are the maximum values of the plurality of D1 and the minimum values of the plurality of D2 obtained by the test between the plurality of sets of first signal transmitting devices 101 and the signal receiving devices 3, and V is the minimum average vehicle speed in the distance between the plurality of sets of pre-garage D1 'and D2'; a is an adjusting coefficient (the default value is 1) which can be set by a user; d1', D2' and V may be determined by a remote or cloud server so as to be downloaded into the signal receiving apparatus 3 when connected to the server.
Further, in an embodiment of the present invention, the controller opens the garage door upon determining that the garage door is in the no-car state upon receiving the garage door opener signal. A parking status indicating whether the garage door is parked with a car may be stored in the buffer memory of the signal receiving device 3, wherein the car-present status and the car-absent status may be represented by 0 and 1, respectively. Whether the garage door is parked or not can be determined according to a pressure sensor (wagon balance) arranged in the garage, if the value of the pressure sensor exceeds a threshold value, the garage door is parked, and if not, the garage door is not parked.
In the embodiment of the present invention, when the signal receiving apparatus 3 in the awake state cannot receive the signal transmitted by the first signal transmitting apparatus 101 for a plurality of consecutive preset time intervals T2, for example, a plurality of consecutive (for example, 5) time intervals, the signal receiving apparatus 3 enters the sleep state.
