Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
The embodiment discloses a control signal generating method based on a UWB positioning system, the UWB positioning system includes a UWB base station installed at one end of a controlled device and a UWB tag installed at one end of a mobile device, as shown in fig. 1, the control signal generating method includes:
s1: the UWB base station detects a positioning signal sent by the UWB tag in real time;
s2: calculating the space position of the mobile equipment according to the positioning signal, and calculating the motion track of the mobile equipment according to the continuous change of the positioning signal;
s3: and generating a control signal for the controlled equipment according to the spatial position and/or the motion trail of the mobile equipment.
In this embodiment, the UWB tag is installed on the mobile device, and the spatial position and the motion trajectory of the mobile device are detected by locating the UWB tag in real time, so as to achieve the purpose of perceiving and recognizing the gesture signal of the user. When a user needs to control the controlled device through some gesture signals, the user only needs to hold the mobile device to make corresponding actions, for example, make the mobile device close to the controlled device or draw some gesture tracks in space. Because the UWB positioning system has better space positioning capability, the controlled equipment can be accurately positioned to the action of the mobile equipment, namely, the gesture signal is more accurately identified.
Specifically, as shown in fig. 2, the controlled device is a motor vehicle, and the mobile device may be any one of a mobile phone, a bracelet, an electronic watch, and the like. The controlled device broadcasts the control signals generated by the positioning of the UWB tag into the bus system (CAN system) of the motor vehicle, from which the respective functional systems on the motor vehicle execute the respective actions by reading the respective control signals.
More specifically, when the mobile device is detected as being located inside the motor vehicle, the control signal includes a first control signal that manipulates a current interface of a center console of the motor vehicle. For example, when the current interface of the console is an entertainment interface and the mobile device with the UWB tag approaches the console for a certain distance (5cm), the console will automatically log in the account corresponding to the UWB tag according to the first control signal; when the current interface of the central console is a Bluetooth connection interface and the mobile equipment with the UWB tag is close to the central console for a certain distance, the central console can automatically complete Bluetooth pairing and connection of the mobile equipment and the motor vehicle according to the first control signal. In addition, in each application interface, corresponding operation is performed by holding the mobile device with the UWB tag to perform corresponding action, for example, in a song listening interface, songs can be switched by sliding the mobile device left and right.
Further, the control signal comprises a second control signal for operating a light and/or a door lock of the motor vehicle when the mobile device is detected to be located outside the motor vehicle. For example, when the mobile device is detected to be located outside the vehicle, through detection of the motion track of the mobile device, if the UWB tag recognizes that the mobile device is performing a circling motion, the vehicle lighting system may give a corresponding response through lighting (flashing, color, brightness, etc.), and if the UWB tag recognizes that the mobile device slides from front to back at the vehicle door, the vehicle door lock system may be automatically unlocked according to the second control signal.
The invention also discloses a control signal generating system based on the UWB positioning system, which comprises a UWB base station, a UWB tag, a processing module and a signal generating module.
The UWB base station is arranged at one end of the controlled equipment, the UWB tag is arranged at one end of the mobile equipment, and the UWB base station is used for detecting a positioning signal sent by the UWB tag in real time;
the processing module is used for calculating the spatial position of the mobile equipment according to the positioning signal and calculating the motion track of the mobile equipment according to the continuous change of the positioning signal;
and the signal generation module is used for generating a control signal for the controlled equipment according to the spatial position and/or the motion trail of the mobile equipment fed back by the processing module.
Preferably, the controlled device is a motor vehicle, and the signal generation module is in communication connection with a bus system of the motor vehicle.
For the working principle and the execution process of the control signal generation system in this embodiment, please refer to the above control signal generation method, which is not described herein again.
The invention also discloses a control signal generation system based on a UWB positioning system, comprising one or more processors, a memory and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, and the program comprises instructions for executing the control signal generation method based on a UWB positioning system as described above.
