Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Please refer to fig. 1-2;

the hand-held light spot indicator can be any remote controller which can emit light spots to control the movement of equipment;

the laser generator 2 installed in the casing can be a light source for LED light condensation, also can be a punctiform laser module, when using, provide the energy to the control module 3 through the power module 4, the controller 31 in the control module 3 sends a signal to the laser generator 2, but because the level detection switch 5 is between the controller 31 and the laser generator 2, when the indicator body 1 is in the horizontal state or the head of the laser generator 2 is placed upwards, the level detection switch 5 is in the closed state, at this moment, the controller 31 can not transmit the signal to the laser generator 2, the laser generator 2 can not be lighted, thus can effectively avoid the damage caused by the light spot directly irradiating the eyes of people due to misoperation, when the head of the laser generator 2 faces downwards, namely, the level detection switch 5 can be switched on to trigger the laser generator 2 only by making the whole downward inclination of the indicator body 1 form a negative angle, a light spot generated at this time is formed on the ground, and a mobile device such as a cleaning robot moves in the direction of the light spot by acquiring diffuse reflection laser light by diffuse reflection laser light formed by irradiating the light spot on the ground;

in this embodiment, the level detecting switch 5 is a mercury switch, also called a tilt switch, which is a small container with electrodes, and stores a small drop of mercury, most of the mercury is vacuum or injected with inert gas, and the mercury drops will flow to the lower part of the container through the action of gravity, if two electrodes are contacted at the same time, the switch will close the circuit, open the switch, and trigger the subsequent circuit operation.

In this embodiment, the horizontal detection switch 5 is an electronic angle sensor, and the embodiment is the same as that described above, but the electronic angle sensor may be configured with the controller 31 to set a conduction angle, so as to further ensure the safety, for example, when the downward inclination angle of the laser generator 2 is greater than 15 °, the electronic angle sensor is turned on;

it should be noted that the controller 31 used in the present invention is a 51-series single chip microcomputer with a programming function, but theoretically, all single chip microcomputers with a programming function can be applied in the present invention, and therefore, the type of the single chip microcomputer used should not be limited.

In this embodiment, the control button 32 electrically connected to the controller 31 is added, when in use, even if the indicator body 1 forms a negative angle, the controller 31 does not send a trigger signal to the laser generator 2 before the control button 32 is not pressed, or the control button 32 is pressed, but the laser generator 2 is not lighted when the head of the laser generator 2 is upward, and the laser generator 2 can be triggered as long as the requirement that the control button 32 and the indicator body 1 are pressed to form a negative angle is met, so that the safety is further improved;

the control button 32 can also be used in combination with the time delay 33, and the trigger signal can be continuously sent to the controller 31 within a set time by pressing the control button 32 through the time delay 33, so that people are not required to continuously press the control button 32, and the use is convenient for people, wherein the set time excludes special requirements, generally does not exceed 30 seconds, for example: 5 seconds or 10 seconds, and is factory set.

In this embodiment, the wireless communication module 6 is provided to communicate with the mobile device such as the cleaning robot, when the orientation of the mobile device such as the cleaning robot needs to be manually controlled, the control button 32 is pressed to transmit an instruction to the controller 31, so that the controller 31 triggers the laser generator 2, and at the same time, the controller 31 sends an instruction to the wireless communication module 6, and the wireless communication module 6 is wirelessly connected with the mobile device such as the cleaning robot to obtain a control right, and then the mobile device such as the cleaning robot moves toward the light spot direction sent by the laser generator 2 according to the description of the above embodiment.
