以下将分别进行详细说明。The details will be described respectively below.
第一实施例first embodiment
在本实施例中,将从基于终端的测速装置的角度进行描述,该基于终端的测速装置具体可以集成在终端上,该终端可以是手机、平板电脑等具有存储单元并安装有微处理器而具有运算能力的终端机。In this embodiment, it will be described from the perspective of a terminal-based speed measuring device, which can be specifically integrated on a terminal, which can be a mobile phone, a tablet computer, etc., which have a storage unit and a microprocessor installed.

一种基于终端的测速方法,包括:当终端接收到测速触发指令时,根据该测速触发指令,控制启动设置于终端上的预设测距传感器;通过预设测距传感器向待测速物体发送第一发射信号;当终端接收到测速停止指令时,通过预设测距传感器向待测速物体发送第二发射信号;基于第一发射信号和第二发射信号,对待测速物体的移动速度进行测量。A speed measurement method based on a terminal, including: when the terminal receives a speed measurement trigger instruction, according to the speed measurement trigger instruction, control and start a preset distance measuring sensor arranged on the terminal; A transmission signal; when the terminal receives a speed measurement stop instruction, the terminal sends a second transmission signal to the object to be measured through the preset range sensor; based on the first transmission signal and the second transmission signal, the moving speed of the object to be measured is measured.
请参阅图1,图1是本发明第一实施例提供的基于终端的测速方法的流程示意图。所述方法包括:Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a terminal-based speed measurement method provided by a first embodiment of the present invention. The methods include:
在步骤S101中,当终端接收到测速触发指令时,根据该测速触发指令,控制启动设置于终端上的预设测距传感器。In step S101, when the terminal receives a speed measurement trigger instruction, according to the speed measurement trigger instruction, it controls to activate a preset distance measuring sensor provided on the terminal.
在步骤S102中,通过预设测距传感器向待测速物体发送第一发射信号。In step S102, a first transmission signal is sent to the object to be measured through a preset distance measuring sensor.
在步骤S103中,当终端接收到测速停止指令时,通过预设测距传感器向待测速物体发送第二发射信号。In step S103, when the terminal receives the instruction to stop the speed measurement, the terminal sends a second transmission signal to the object to be measured through the preset range sensor.
其中,所述步骤S101至步骤S103可具体为:Wherein, the steps S101 to S103 may specifically be:
在本发明实施例中,终端可以具体是手机、平板电脑等具有存储单元并安装有微处理器而具有运算能力的终端机;其中,该终端上设置有测距传感器,用于对待测速物体移动的距离进行检测。In the embodiment of the present invention, the terminal can specifically be a mobile phone, a tablet computer, etc., which has a storage unit and is installed with a microprocessor and has computing capabilities; wherein, the terminal is provided with a ranging sensor for moving the object to be measured. distance to detect.
可以理解的是,该预设测距传感器可以具体是光波传感器(如激光传感器、红外传感器)以及超声波传感器等等,此处不作具体限定。It can be understood that the preset ranging sensor may specifically be a light wave sensor (such as a laser sensor, an infrared sensor) and an ultrasonic sensor, etc., which are not specifically limited here.
可具体的,比如,在终端接收到测速触发指令,即用户通过终端触发开启测距传感器时,向该测距传感器发送第一控制信号,以控制通过预设测距传感器向待测速物体发送第一发射信号。Specifically, for example, when the terminal receives the speed measurement trigger instruction, that is, when the user triggers the distance measurement sensor to be turned on through the terminal, it sends the first control signal to the distance measurement sensor, so as to control the preset distance measurement sensor to send the first control signal to the object to be measured. A signal is transmitted.
进一步的,在通过预设测距传感器向待测速物体发送第一发射信号之后,还可以包括:Further, after the first transmission signal is sent to the object to be measured by the preset distance measuring sensor, it may also include:
步骤S1021、获取该第一发射信号发送至待测速物体后返回的第一反射信号。Step S1021. Obtain a first reflected signal returned after the first transmitted signal is sent to the object to be measured.
步骤S1022、基于该第一发射信号和该第一反射信号,确定第一时间信息。Step S1022. Based on the first transmitted signal and the first reflected signal, determine first time information.
也就是说,测距传感器向待测速物体发送第一发射信号,第一发射信号遇到待测速物体后会接收返回的第一反射信号,从而可以根据第一发射信号和第一反射信号,确定出第一时间信息。That is to say, the distance measuring sensor sends the first transmission signal to the object to be measured, and the first transmission signal will receive the returned first reflection signal after encountering the object to be measured, so that it can be determined according to the first transmission signal and the first reflection signal Out of the first time information.
可以理解的是,在待测速物体在移动的过程中,当在终端接收到测速停止指令,比如,用户通过终端关闭测距传感器时,向该测距传感器发送第二控制信号,以控制通过预设测距传感器向待测速物体发送第二发射信号;又比如,按照预定的时间间隔,向测距传感器发送第二控制信号,以控制通过预设测距传感器向待测速物体发送第二发射信号,从而可以根据两次发射信号检测速度。It can be understood that, during the moving process of the object to be measured, when the terminal receives a speed measurement stop instruction, for example, when the user turns off the distance measuring sensor through the terminal, a second control signal is sent to the distance measuring sensor to control the speed measurement through the It is assumed that the distance measuring sensor sends a second transmission signal to the object to be measured; for another example, according to a predetermined time interval, a second control signal is sent to the distance measurement sensor to control the transmission of the second transmission signal to the object to be measured by the preset distance measurement sensor , so that the speed can be detected from the two emission signals.
更进一步的,通过预设测距传感器向待测速物体发送第二发射信号之后,还可以包括:Furthermore, after the second transmission signal is sent to the object to be measured by the preset distance measuring sensor, it may also include:
步骤S1031、获取该第二发射信号发送至待测速物体后返回的第二反射信号;Step S1031, acquiring a second reflected signal returned after the second transmitted signal is sent to the object to be measured;
步骤S1032、基于该第二发射信号和该第二反射信号,确定第二时间信息。Step S1032: Determine second time information based on the second transmitted signal and the second reflected signal.
也就是说,测距传感器向待测速物体发送第二发射信号,第二发射信号遇到待测速物体后会接收返回的第二反射信号,从而可以根据第二发射信号和第二反射信号,确定出第二时间信息。That is to say, the distance measuring sensor sends a second transmission signal to the object to be measured, and the second transmission signal will receive the returned second reflection signal after encountering the object to be measured, so that it can be determined according to the second transmission signal and the second reflection signal Out of the second time information.
容易想到的是,本发明实施例中的“第一”、“第二”仅为了区别说明,不构成对本发明实施的限定。It is easy to think that "first" and "second" in the embodiments of the present invention are only for distinction and description, and do not constitute a limitation to the implementation of the present invention.
在步骤S104中,基于第一发射信号和第二发射信号,对待测速物体的移动速度进行测量。In step S104, based on the first transmission signal and the second transmission signal, the moving speed of the object to be measured is measured.
可以理解的是,在基于第一发射信号和第二发射信号,对待测速物体的移动速度进行测量之前,还可以包括:It can be understood that, before measuring the moving speed of the object to be measured based on the first transmitted signal and the second transmitted signal, it may further include:
记录向待测速物体发送第一发射信号以及向待测速物体发送第二发射信号的时间差。The time difference between sending the first transmission signal to the object to be measured and the time difference between sending the second transmission signal to the object to be measured is recorded.
比如,在终端发送第一发射信号时,记录当前时间为T1,在终端发送第二发射信号时,记录当前时间为T2,从而根据T1和T2计算出时间差,其中该时间差可以认为是终端移动的时间。For example, when the terminal sends the first transmission signal, record the current time as T1, and when the terminal sends the second transmission signal, record the current time as T2, so as to calculate the time difference based on T1 and T2, where the time difference can be considered as the time of terminal movement time.
在某些实施方式中,也可以根据终端接收返回的第一反射信号以及第二反射信号的时间信息,来确定时间差。In some implementation manners, the time difference may also be determined according to time information of the first reflected signal and the returned second reflected signal received by the terminal.
在本实施例中,基于第一发射信号和第二发射信号,对待测速物体的移动速度进行测量可以具体包括:In this embodiment, based on the first transmission signal and the second transmission signal, measuring the moving speed of the object to be measured may specifically include:
步骤S1041、基于该第一时间信息与该第二时间信息,确定待测速物体的移动距离。Step S1041, based on the first time information and the second time information, determine the moving distance of the object to be measured.
步骤S1042、根据移动距离与时间差,对待测速物体的移动速度进行测量。Step S1042, measure the moving speed of the object to be measured according to the moving distance and the time difference.
比如,预设测速传感器可以具体为光波传感器,由于是光波传输,因此可以根据光速、第一时间信息以及第二时间信息,确定出待测速物体的移动距离。For example, the preset speed sensor may specifically be a light wave sensor. Since it is light wave transmission, the moving distance of the object to be measured can be determined according to the speed of light, the first time information and the second time information.
进一步的,可以根据移动距离与时间差,估算出待测速物体的平均移动速度,显然,时间差的时间越小,可以使计算出的待测速物体的瞬时速度更加准确。Further, the average moving speed of the object to be measured can be estimated according to the moving distance and the time difference. Obviously, the smaller the time difference, the more accurate the calculated instantaneous speed of the object to be measured can be.
另外,优选的,在终端接收到测速停止指令时,可以根据该测速停止指令,控制及时关闭预设测距传感器,从而可以使终端达到续航的效果。In addition, preferably, when the terminal receives the speed measurement stop instruction, it can control to turn off the preset distance measuring sensor in time according to the speed measurement stop instruction, so that the terminal can achieve the effect of battery life.
由上述可知,本实施例提供的基于终端的测速方法,首先,在终端接收到测速触发指令时,控制启动设置于终端上的预设测距传感器,并通过该测距传感器向待测速物体发送第一发射信号;然后,在终端进行移动的过程中,在终端接收到测速停止指令时,通过该测距传感器向待测速物体发送第二发射信号,最后结合第一发射信号和第二发射信号,对待测速物体的移动速度进行测量;即本发明实施例直接在终端上设置测距传感器,在物体开始移动和停止移动时,分别通过该测距传感器发送发射信号来定位,从而在终端静止时,也可以对终端之外的移动物体进行速度测量,提高了测速操作的灵活性和便利性。It can be seen from the above that, in the terminal-based speed measurement method provided by this embodiment, first, when the terminal receives a speed measurement trigger command, it controls to start the preset distance measuring sensor installed on the terminal, and sends a message to the object to be measured through the distance measurement sensor. The first transmission signal; then, when the terminal receives the speed measurement stop command during the movement of the terminal, the second transmission signal is sent to the object to be measured through the distance measuring sensor, and finally the first transmission signal and the second transmission signal are combined , to measure the moving speed of the object to be measured; that is, in the embodiment of the present invention, a distance measuring sensor is directly set on the terminal, and when the object starts to move and stops moving, the distance measuring sensor is used to send a transmission signal for positioning, so that when the terminal is stationary , It can also measure the speed of moving objects other than the terminal, which improves the flexibility and convenience of the speed measurement operation.
第二实施例second embodiment
根据第一实施例所描述的方法,以下将举例作进一步详细说明。According to the method described in the first embodiment, an example will be given below for further detailed description.
请参阅图2a,图2a为本发明第二实施例提供的基于终端的测速方法的流程示意图。该实施例中,以终端是手机为例,提供手机对移动物体进行测速的方法,其中,该方法步骤包括:Please refer to FIG. 2a. FIG. 2a is a schematic flowchart of a terminal-based speed measurement method provided by a second embodiment of the present invention. In this embodiment, taking the terminal as a mobile phone as an example, a method for measuring the speed of a moving object by a mobile phone is provided, wherein the method steps include:
在步骤S201中,手机接收到测速触发指令时,控制启动设置于手机上的激光传感器。In step S201, when the mobile phone receives a speed measurement trigger command, it controls to activate the laser sensor provided on the mobile phone.
可以理解的是,随着半导体技术的发展,激光传感器的方案也越来越多的应用于电子产品中,其中较成熟的是砷化镓激光器,特点是效率高、体积小、重量轻、结构简单、输出功率较小等,因此本发明测距传感器可以优选为砷化镓激光器。It is understandable that with the development of semiconductor technology, more and more laser sensor solutions are used in electronic products, among which gallium arsenide lasers are more mature, which are characterized by high efficiency, small size, light weight, and structure Simple, low output power, etc., so the ranging sensor of the present invention can preferably be a gallium arsenide laser.
优选的,本实施例考虑到手机测距的场景,将激光发射器端设计在电池后盖面或者侧边(依据不同的需求),可一并参考图2b,为手机上的激光传感器的设置示意图,如,可以在手机电池后盖上端设置激光开孔区域,这样人们在对物体运动速度进行测试时可以方便操作。Preferably, this embodiment considers the scene of mobile phone distance measurement, and designs the laser transmitter end on the battery back cover or side (according to different requirements), and can refer to Figure 2b together, which is the setting of the laser sensor on the mobile phone Schematic diagram, for example, a laser opening area can be set on the upper end of the battery back cover of the mobile phone, so that people can easily operate when testing the speed of the object.
在步骤S202中,手机通过该激光传感器向待测速物体发射第一脉冲。In step S202, the mobile phone transmits a first pulse to the object to be measured through the laser sensor.
在步骤S203中,手机接收第一脉冲的反射激光,并记录时间为t1。In step S203, the mobile phone receives the first pulse of reflected laser light, and records the time as t1.
在步骤S204中,经过预设时间Δt,手机通过该激光传感器向待测速物体发射第二脉冲。In step S204, after a preset time Δt, the mobile phone transmits a second pulse to the object to be measured through the laser sensor.
在步骤S205中,手机接收第二脉冲的反射激光,并记录时间为t2。In step S205, the mobile phone receives the second pulse of reflected laser light, and records the time as t2.
在步骤S206中,手机根据t1和t2,确定对应的距离S。In step S206, the mobile phone determines the corresponding distance S according to t1 and t2.
在步骤S207中,手机根据预设时间Δt以及距离S,对待测速物体的速度进行测量。In step S207, the mobile phone measures the speed of the object to be measured according to the preset time Δt and the distance S.
其中,所述步骤S202至步骤S207可具体为:Wherein, the steps S202 to S207 may specifically be:
比如,激光传感器工作时,先由激光发射二极管对准目标物体(即待测速物体)发射激光脉冲,激光脉冲遇到目标物体时会返回到激光传感器接收端,此时激光传感器会计算出激光从发射到接收回来的时间。由于光速非常快,光速约为c=3*10^8m/s,因此可以实时测试出目标物体相对测试点的距离。For example, when the laser sensor is working, the laser emitting diode is aimed at the target object (that is, the object to be measured) to emit laser pulses. When the laser pulse encounters the target object, it will return to the receiving end of the laser sensor. At this time, the laser sensor will calculate the laser from the emission to the time it is received. Since the speed of light is very fast, the speed of light is about c=3*10^8m/s, so the distance between the target object and the test point can be tested in real time.
进一步的,速度计算方法可以具体如下:Further, the speed calculation method can be specifically as follows:
(1)当开始测试速度时,激光传感器发射第一次脉冲(即第一脉冲),当激光传感器接收到反射激光后,记录时间为t1;(1) When starting to test the speed, the laser sensor emits the first pulse (that is, the first pulse), and when the laser sensor receives the reflected laser light, the recording time is t1;
(2)经过时间Δt(如1s等),激光传感器发射第二次脉冲(即第二脉冲),当激光传感器接收到反射激光后,记录时间为t2;(2) After the time Δt (such as 1s, etc.), the laser sensor emits the second pulse (ie the second pulse), when the laser sensor receives the reflected laser light, the recording time is t2;
(3)由于光速传播,加上记录的两次时间为t1,t2,因此即可得知两次时间对应的距离S=(c*t2-c*t1)/2,同时得知这段距离的时间差为Δt,因此可以得知Δt时间内的平均速度。(3) Due to the speed of light propagation, plus the two recorded times are t1 and t2, the distance corresponding to the two times can be known as S=(c*t2-c*t1)/2, and this distance can be known at the same time The time difference is Δt, so the average speed within Δt time can be known.
可以理解的是,本实施例中,假设Δt时间越小,则计算的到的速度(即瞬时速度)越准确;在该实施例中,Δt可以进行预先设置,从而根据两次发射的脉冲信号计算得到移动速度,在某些实施例中,发射的脉冲信号也可以由用户进行设定,即在开始移动以及停止移动时,分别控制激光传感器发射脉冲信号,同样的,根据两次发射的脉冲信号计算得到移动速度。It can be understood that in this embodiment, assuming that the Δt time is smaller, the calculated speed (ie, instantaneous speed) is more accurate; in this embodiment, Δt can be preset, so that according to the pulse signal transmitted twice The moving speed is calculated. In some embodiments, the emitted pulse signal can also be set by the user, that is, when starting to move and stopping moving, the laser sensor is respectively controlled to emit a pulse signal. Similarly, according to the two emitted pulses The signal is calculated to get the movement speed.
另外容易想到的是,本发明实施例中,激光传感器也可以为其他类型的传感器,若为红外等其他光波传感器,则可以按照上述计算方法进行计算,若为超声波等声波传感器,则可以根据声波的传输速度计算出移动距离,从而计算出速度等,此处不作具体限定。In addition, it is easy to imagine that in the embodiment of the present invention, the laser sensor can also be other types of sensors. If it is another light wave sensor such as infrared, it can be calculated according to the above calculation method; The transmission speed is used to calculate the moving distance, thereby calculating the speed, etc., which are not specifically limited here.
由上述可知,本实施例提供的基于终端的测速方法,首先,在终端接收到测速触发指令时,控制启动设置于终端上的预设测距传感器,并通过该测距传感器向待测速物体发送第一发射信号;然后,在终端进行移动的过程中,在终端接收到测速停止指令时,通过该测距传感器向待测速物体发送第二发射信号,最后结合第一发射信号和第二发射信号,对待测速物体的移动速度进行测量;即本发明实施例直接在终端上设置测距传感器,在物体开始移动和停止移动时,分别通过该测距传感器发送发射信号来定位,从而在终端静止时,也可以对终端之外的移动物体进行速度测量,提高了测速操作的灵活性和便利性。It can be seen from the above that, in the terminal-based speed measurement method provided by this embodiment, first, when the terminal receives a speed measurement trigger command, it controls to start the preset distance measuring sensor installed on the terminal, and sends a message to the object to be measured through the distance measurement sensor. The first transmission signal; then, when the terminal receives the speed measurement stop command during the movement of the terminal, the second transmission signal is sent to the object to be measured through the distance measuring sensor, and finally the first transmission signal and the second transmission signal are combined , to measure the moving speed of the object to be measured; that is, in the embodiment of the present invention, a distance measuring sensor is directly set on the terminal, and when the object starts to move and stops moving, the distance measuring sensor is used to send a transmission signal for positioning, so that when the terminal is stationary , It can also measure the speed of moving objects other than the terminal, which improves the flexibility and convenience of the speed measurement operation.

可具体的,比如,在终端接收到测速触发指令,即用户通过终端触发开启测距传感器时,向该测距传感器发送第一控制信号,以控制通过预设测距传感器向待测速物体发送第一发射信号。Specifically, for example, when the terminal receives the speed measurement trigger instruction, that is, when the user triggers the distance measurement sensor to be turned on through the terminal, it sends the first control signal to the distance measurement sensor, so as to control the preset distance measurement sensor to send the first control signal to the object to be measured. A signal is transmitted.
进一步的,可一并参考图3b,为本发明第三实施例提供的基于终端的测速装置的另一结构示意图,其中该基于终端的测速装置还可以包括:Further, reference can be made to FIG. 3b, which is another structural schematic diagram of a terminal-based speed measuring device provided in the third embodiment of the present invention, wherein the terminal-based speed measuring device may further include:
第一获取单元305,用于获取所述第一发射信号发送至待测速物体后返回的第一反射信号;第一确定单元306,用于基于所述第一发射信号和所述第一反射信号,确定第一时间信息。The first acquiring unit 305 is configured to acquire the first reflected signal returned after the first transmitted signal is sent to the object to be measured; the first determining unit 306 is configured to based on the first transmitted signal and the first reflected signal , to determine the first time information.
也就是说,测距传感器向待测速物体发送第一发射信号,第一发射信号遇到待测速物体后会接收返回的第一反射信号,从而可以根据第一发射信号和第一反射信号,确定出第一时间信息。That is to say, the distance measuring sensor sends the first transmission signal to the object to be measured, and the first transmission signal will receive the returned first reflection signal after encountering the object to be measured, so that it can be determined according to the first transmission signal and the first reflection signal Out of the first time information.
可以理解的是,在待测速物体在移动的过程中,当在终端接收到测速停止指令,即用户通过终端关闭测距传感器时,向该测距传感器发送第二控制信号,以控制通过预设测距传感器向待测速物体发送第二发射信号。It can be understood that, during the moving process of the object to be measured, when the terminal receives a speed measurement stop command, that is, when the user turns off the distance measuring sensor through the terminal, a second control signal is sent to the distance measuring sensor to control the distance through the preset The distance measuring sensor sends a second transmission signal to the object to be measured.

容易想到的是,本发明实施例中的“第一”、“第二”仅为了区别说明,不构成对本发明实施的限定。It is easy to think that "first" and "second" in the embodiments of the present invention are only for distinction and description, and do not constitute a limitation to the implementation of the present invention.
可以理解的是,所述基于终端的测速装置还可以包括:It can be understood that the terminal-based speed measurement device may also include:
记录单元309,用于记录向待测速物体发送第一发射信号以及向待测速物体发送第二发射信号的时间差。The recording unit 309 is configured to record the time difference between sending the first transmission signal to the object to be measured and the time difference between sending the second transmission signal to the object to be measured.
比如,在终端发送第一发射信号时,记录当前时间为T1,在终端发送第二发射信号时,记录当前时间为T2,从而根据T1和T2计算出时间差,其中该时间差可以认为是终端移动的时间。For example, when the terminal sends the first transmission signal, record the current time as T1, and when the terminal sends the second transmission signal, record the current time as T2, so as to calculate the time difference based on T1 and T2, where the time difference can be considered as the time of terminal movement time.

比如,预设测速传感器可以具体为光波传感器,由于是光波传输,因此可以根据光速、第一时间信息以及第二时间信息,确定出待测速物体的移动距离。For example, the preset speed sensor may specifically be a light wave sensor. Since it is light wave transmission, the moving distance of the object to be measured can be determined according to the speed of light, the first time information and the second time information.
进一步的,可以根据移动距离与时间差,估算出待测速物体的平均移动速度,显然,时间差的时间越小,可以使计算出的待测速物体的瞬时速度更加准确。Further, the average moving speed of the object to be measured can be estimated according to the moving distance and the time difference. Obviously, the smaller the time difference, the more accurate the calculated instantaneous speed of the object to be measured can be.
