Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of examples of specific embodiments. However, it should be understood by those skilled in the art that the present invention is not limited to the specific embodiments listed, and should be included within the scope of the present invention as long as the spirit of the present invention is met.
Fig. 1 shows a block diagram of a voice-controlled rescue position indicating device claimed in the present invention. The device includes a housing. The main control unit in the shell is connected with and controls the voice recognition module, the command set storage module, the GNSS positioning module and the like.
A voice control rescue position indicating device comprises a voice sensor, an amplifier, a comparator, an A/D converter, a voice recognition module, a command set storage module, a GNSS positioning module, a satellite communication module, an antenna and a main control unit.
The acoustic sensor is used for collecting voice signals input by a user, and can be realized by a microphone. The voice signal is amplified from the output end of the acoustic sensor through the amplifier, and then processed by the comparator. The comparator compares the amplified voice signal with a preset threshold value, and sends a wake-up signal to the main control unit when the amplitude of the voice signal is greater than the threshold value.
After the operation of waking up the device is executed, the device enters a standby state and waits for the user to input the voice command again.
After the voice instruction words input by the user are collected by the acoustic sensor, the voice instruction words are amplified by the amplifier, sent to the A/D converter for processing, converted into digital signals and then transmitted to the voice recognition module for semantic analysis. The voice recognition module matches the voice content recognized from the voice command with a preset command pre-stored in the command set storage module. If the matching is successful, informing the main control unit to execute a corresponding instruction; otherwise, the main control unit is informed to ignore the voice instruction.
The instruction content may include: location, whistling, etc.
When the voice instruction is positioning, the main control unit sends a positioning instruction to the GNSS positioning module, the GNSS positioning module is communicated with a satellite to obtain the GNSS position of the rescue position indicating device, and GNSS positioning information is sent to the main control unit. Furthermore, the main control unit can process the GNSS positioning information through the satellite communication module and send the processed GNSS positioning information to nearby or distant rescue personnel through the antenna.
The satellite communication module comprises an 12.68875MHz temperature compensation crystal oscillator, a phase modulator, a 406MHz phase-locked loop, a power amplifier and a band-pass filter which are sequentially connected, and is used for processing distress information in GNSS positioning information received from a satellite; the GNSS positioning system also comprises a 121.5MHz crystal oscillator, an ASK amplitude keying modulation circuit, a power amplifier and a band-pass filter which are connected in sequence and used for processing the sweep frequency tone carrying GNSS positioning information; the 12.68875MHz temperature compensation crystal oscillator and the 121.5MHz crystal oscillator are both connected to the main control unit and used for acquiring information to be processed from the main control unit; the band-pass filters are connected with the antenna; the antenna is used for sending the processed information to the GNSS network.
When the voice command is 'whistling', the preset audio is played by using the external sound playing ring.
The wake-up action can be triggered by voice control and can be realized by manual operation. A switch is arranged on a shell of the rescue position indicating device. Furthermore, a timer is arranged in the switch circuit, the time for pressing the switch is detected, and when the time for keeping the switch in a pressed state reaches a preset time length, the awakening action is executed. For example, it is set that when the on-off key is pressed for 3 seconds, the wake-up action is performed.
When the switch is used for awakening the equipment, the voice awakening process can be skipped, the instruction identification step is directly carried out, and the user is waited to input the voice instruction and identify the voice instruction.
The voice-controlled rescue position indicating device further comprises a recording storage module connected with the main control unit and used for storing all voices collected from the voice sensor in the recording storage module. The recording function is used for recording the situation of the scene of the distress really, so as to carry out accident investigation and restore the situation of the distress at the later stage, and can record the left message of the person in distress, thereby providing psychological comfort for the person in distress. And after the alarm function is triggered, the recording storage module starts to work. The recording storage module can detect environmental sounds, automatically start recording when voice is recognized, and pause recording when no voice signal exists in the environment. The sound recording storage module can also store the time stamp generated by the sound recording.
It should be noted that the above-mentioned embodiments illustrate rather than limit the utility model, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims. While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts.
