Problems solved by technology
The traditional speed measurement scheme usually adopts the opposite beam method, that is, a pair of optical transceiver sensors are installed on both sides of the channel, and the optical signal emitted by the optical transmitting sensor is received by the optical receiving sensor. When the optical receiving sensor does not receive the optical signal, it indicates that there is an object By recording the time, at least two pairs of optical transceiver sensors are used to calculate the moving speed of the object. However, since the optical transceiver sensors need to be installed on both sides of the channel through which the object passes, the separately designed structure consumes more hardware resources and costs more.

The invention discloses a projectile launching system (100) and method and a movable platform (001). The projectile launching system (100) comprises a launching speed detection module (11) and at least two detection modules (12), the lunching speed detection module (11) is respectively connected with the at least two detection modules (12); the detection module (12) comprises a pair of light emitting sensor (121) and light receiving sensor (122), and the light emitting sensor (121) and the light receiving sensor (122) are located on the same circuit board (123); the light emitting sensor (121)is used for emitting a light signal in a direction not facing the light receiving sensor (122); the light receiving sensor (122) is used for receiving a light signal reflected by the projectile and feeding back the light signal to the firing speed detection module (11); and the lunching speed detection module (11) is used for determining a time difference based on the time when the at least two light receiving sensors (122) receive the light signals respectively, and determining the lunching speed of the projectile according to the time difference and the distance between the detection modules (12) where the light receiving sensors (122) receiving the light signals are located respectively, so that a low-cost speed measurement process is realized.
Description
technical field [0001] The present application relates to the field of moving speed measurement, in particular to a projectile launching system, method and movable platform. Background technique [0002] In practice in life, we often encounter various occasions where it is necessary to measure the moving speed of an object. The traditional speed measurement scheme usually adopts the opposite beam method, that is, a pair of optical transceiver sensors are installed on both sides of the channel, and the optical signal emitted by the optical transmitting sensor is received by the optical receiving sensor. When the optical receiving sensor does not receive the optical signal, it indicates that there is an object By recording the time, at least two pairs of optical transceiver sensors are used to calculate the moving speed of the object. However, since the optical transceiver sensors need to be installed on both sides of the channel through which the object passes, the separately...
