Embodiment Construction

[0032] see figure 1 , figure 1 It is a schematic diagram of an application aspect of an electronic device 10 according to an embodiment of the present invention. The electronic device 10 can be a driving recorder, which uses the technology of video recording and recording to save the driving information of the vehicle. Therefore, the electronic device 10 is installed on a transmission source 12 (i.e. the vehicle). The transmission source 12 can include There is a processor 121, and the processor 121 detects a moving speed V of the emission source 12 at any time 12 , and the electronic device 10 can be electrically connected to the processor 121 to obtain its moving speed V 12 value. In addition to the existing video recording and recording technology, the electronic device 10 of the present invention also has the ability to use the Doppler effect to measure a moving velocity V of an external object 14 around the emission source 12. 14 The function can detect the driving sp...

Abstract

A method of detecting a vehicle speed is disclosed in the present invention. The method includes outputting a detecting wave, receiving a reflecting wave from an external object when the external object passes through a covering range of the detecting wave, calculating a variation between the detecting wave and the reflecting wave, and reading a table for executing an application program according to information of the table.

Description

technical field [0001] The present invention relates to a speed measuring method and its related electronic device, in particular to a speed measuring method and its related electronic device which are arranged on an active emission source to measure the moving speed of an external object. Background technique [0002] Vehicles on the market, such as passenger cars, freight container trucks, and large tour buses, are mostly equipped with driving recorders, which can record the surrounding environment information of the vehicle in the form of video and audio recording at any time. When a car accident occurs, it can be According to the recorded content of the driving recorder, the attribution of responsibility for the accident is judged. However, the traditional driving recorder can only use the recorded images to clarify the cause of the accident after the accident, and cannot prevent the accident in advance. Therefore, if the function of the traditional driving recorder can...
