Embodiment 1

[0036] In the preferred embodiment 1 of the present invention, a laser charging protection method is provided, which can be directly applied to various laser charging devices, and can also be applied to other devices with partial functions of laser charging. Specifically, figure 1 An alternative flowchart showing the method, such as figure 1 As shown, the method includes the following steps S102-S106:

[0037] S102: Transmitting an ultrasonic detection signal, and receiving an ultrasonic reflection signal fed back after the ultrasonic detection signal encounters an object;

[0038] In the present invention, ultrasonic wave is used as the detection signal for detecting whether there is an object approaching the laser charging device. When detection is required, an ultrasonic detection signal is emitted to the surrounding area of ​​the laser charging device. When the ultrasonic detection signal encounters an object in the surrounding area of ​​the laser charging device, the ob...

Embodiment 2

[0051] Based on the laser charging protection method provided in the above-mentioned embodiment 1, a laser charging protection device is also provided in the preferred embodiment 2 of the present invention, specifically, image 3 shows an optional structural block diagram of the device, such as image 3 As shown, the device includes:

[0052] The detection module 302 is configured to transmit an ultrasonic detection signal, and receive an ultrasonic reflection signal fed back after the ultrasonic detection signal encounters an object;

[0053] Judgment module 304, connected with detection module 302, is used for judging whether the distance between the object and the laser charging area of ​​the laser charging device is in a shortening trend according to the ultrasonic detection signal and the ultrasonic reflection signal;

[0054] The control module 306 is connected with the judging module 304, and is configured to control the laser charging device to stop charging when it is ...

Embodiment 3

[0059] Another laser charging protection device is also provided in preferred embodiment 3 of the present invention, specifically, Figure 4 shows an optional structural block diagram of the device, such as Figure 4 As shown, the device includes:

[0060] Ultrasonic transmitting device (1), used for transmitting ultrasonic detection signal;

[0061] Ultrasonic receiving device (6), is used for receiving the ultrasonic reflection signal that the ultrasonic detection signal meets the object feedback;

[0062] In the present invention, ultrasonic wave is used as the detection signal for detecting whether there is an object approaching the laser charging device. like Figure 5 As shown, when the laser is charging, the laser emitting device emits a laser beam to the laser receiving device. At this time, the ultrasonic emitting device emits an ultrasonic beam (ultrasonic detection signal) to detect whether there is a foreign object close to the laser charging area. When the emi...

Abstract

The invention discloses a laser charging protection method and device. The method comprises the following steps of transmitting an ultrasonic detection signal, and receiving an ultrasonic reflected signal fed back after the ultrasonic detection signal encounters an object; judging whether a distance between the object and a laser charging area of a laser charging device is in a shortened trend ornot according to the ultrasonic detection signal and the ultrasonic reflected signal; and controlling the laser charging device to stop charging when the distance is determined to be in the shortenedtrend. According to the method and the device, a problem that the safety of the laser charging device is not high in the prior art is solved, and the safety of the laser charging device is improved.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a laser charging protection method and device. Background technique [0002] The current method of charging electrical equipment based on laser transmission energy has the characteristics of long transmission distance and small charging blind area, but the energy of laser is highly concentrated, and if there is no protection device, it will cause damage to other objects. [0003] The prior art provides a long-distance laser charging device with protective measures, but this protective measure only relies on a fixed laser beam to sense whether an object is approaching. The object is already in contact with the charging laser beam, rendering the protective measures ineffective. The existing laser charging protection device has a single protection mode, and its safety and reliability need to be improved. [0004] Aiming at the problem of low safety of the laser charging device in t...
