An embodiment of the technical solution based on the present invention will now be described with reference to Figs. 3A to 3E, wherein Figs. 3A to 3E show schematic views of a remote controller according to an embodiment of the present invention.

As shown, an infrared sensor 306 can be provided on the remote control 300. The infrared sensor 306 includes at least one set of launch tubes 306A and a receiving tube 306B, which will transmit tubes 306A and receive The tube 306B is correspondingly disposed on the frame 308 of the operation panel 302. For example, the infrared sensor 306 is disposed on the upper and lower sides of the frame 308, or the infrared sensor 306 is disposed on the left and right sides of the frame 308 to ensure that the infrared rays from the transmitting tube 306A can be received by the receiving tube 306B. To be of course, the infrared sensor 306 can also be disposed at the same time, up and down, left and right, etc., and when the setting is completed, the infrared ray can be interwoven into a coverage surface to cover the operation panel 302, so that when the user needs to operate the handle 304 or other components, etc. At this time, it is inevitably passed through a face made of infrared rays. Therefore, if the receiving tube 306B does not receive the signal of the transmitting tube 306A, it indicates that there is an object in the area between the transmitting tube 306A and the receiving tube 306B. Of course, a time threshold may also be set, for example, 3 seconds. When the continuous blocking time exceeds 3 seconds, it is judged that the user is going to operate, otherwise it is considered that a malfunction has occurred, and it is not necessary to perform an operation. When it is determined that the user is about to perform an operation, the remote controller 300 is allowed to receive an external operation command; when the receiving tube 306B can receive the signal of the transmitting tube 306A, it is determined that there is no object in the area between the transmitting tube 306 A and the receiving tube 306B. Existence, a time threshold can be set at this time. For example, if the infrared light is received for more than 10 seconds, it is determined that the user has left, and the protection state of the remote controller 100 will be activated. In this state, the key operation of the remote controller 300 Parts can not be operated, and some such as emergency stop are still retained, to avoid the malfunction caused by unexpected conditions such as falling, collision, etc. of the remote control 300, of course, it is also obvious that all functions can be locked. In addition, in the protection state, or after a longer time, such as 5 minutes, some key components such as a display, a hard disk, and the like can be powered off, thereby reducing damage to the remote controller 300 caused by an unexpected situation.

In order to improve the anti-interference ability of the infrared sensor 306, a filter 310 may be disposed between the transmitting tube 306A and the receiving tube 306B so that only electromagnetic waves having a wavelength close to the infrared ray emitted by the infrared sensor 306 can pass. It is also possible to further improve the anti-interference ability of the infrared sensor 306 by staggering the transmitting tube 306A and the receiving tube 306B.

Of course, infrared sensor 306 is used as an embodiment here, and for others, for example. Laser sensors and the like are obviously also usable in the present invention.

In addition, the human body sensor 312 may be disposed on the remote controller 300 to detect whether a human body exists in a certain sensing range 314. When the detection result is that no human body exists, the remote controller 300 is not allowed even if an object exists in the operating area. The external operation command is received to make the determination result more accurate. When there is a human body in the sensing range 314, it is determined whether to activate the protection state of the remote controller 300 according to the judgment of the operation area.

The monitoring method of the human body sensor 312 may be to collect images from the surroundings. When the acquired image is inconsistent with the preset image, it is determined that there is a human body; or the parameters of the surrounding environment may be monitored, such as temperature, light, When the parameter changes to the preset standard, it is judged that there is a human body in the monitored range.

Further, in some cases, the user is required to operate the remote controller 300 on the body, and therefore, it can be judged based on whether or not the remote controller 300 is picked up by the user. Specifically, the present invention includes: a strap buckle 316 is disposed on the frame 308 of the remote controller 300, and a force sensor 318 is disposed at the strap buckle 316. When the value of the force sensed by the force sensor 318 reaches a preset threshold, the user is determined to be present. , and cancel the protection status, receive the normal operation of the user, otherwise enter the protection state.

In addition, an LED lamp 320 can be provided on the remote controller 300 for illumination during nighttime operation, which makes the use of the remote controller 300 more convenient and reduces the risk of accidents.

In summary, by detecting the operation area, it is judged whether someone is operating the remote controller, and when there is no one, starting the protection state of the remote controller can prevent the occurrence of malfunction and the safety hazard caused by the malfunction; The area around the remote control can be detected to determine whether there is someone nearby. When there is no one, only other objects in the operation area exist, and the protection state of the remote controller is not released, thereby improving the accuracy of the judgment, and better Preventing the occurrence of malfunctions; In addition, the protection status of the remote controller may include not only rejecting the external operation command of the remote controller, but also including de-energizing the designated components of the remote controller, which not only prevents the remote control The malfunction of the controller can also better protect the electronic components inside the remote control.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention. Industrial applicability

When there is no one, only other objects in the operation area exist, and the protection status of the remote controller is not released, and the accuracy of the judgment is improved. In addition, the protection status of the remote controller can not only include the rejection of the external operation command of the remote controller, but also includes the power-off processing of the designated components of the remote controller, which can not only prevent the remote controller from being operated. Malfunctions can also better protect the electronic components inside the remote control. Therefore, the present invention has industrial applicability.
