Detailed Description

The technical solution of the present invention will be clear and fully described with reference to the accompanying drawings.

As shown in fig. 1, the upper part 1 of the strop hook is the friction part of the hook and the strop; the lower part 4 of the sliding rope hook is used for bolting safety equipment on a tourist, the strong magnet 3 is arranged at the sliding end 2 of the hook and can slide up and down, and the Hall element 5 is arranged at the fixed end of the hook close to the magnet. When the sliding end 2 slides up and down, the hall element detects the position of the magnet, which represents the opening and closing of the hook. The Hall element is connected to the control box through a thin cable, a signal is subjected to a conditioning circuit to obtain a switching value, and the switching value is used for detecting the state of the hook for the MCU.

As shown in fig. 2, the upper and lower control boxes are respectively provided with two keys and a speaker, and the two control boxes communicate through LoRa communication. The keys on device 1 are used to wake up the lower device (key a) and cancel the operation (key B), and the keys on device 2 are used to answer the upper device (key C) and cancel the operation (D). The four keys are keys with electromagnet control, and if the four keys do not accord with the following operation sequence and logic, the corresponding keys cannot be pressed. The loudspeaker is used for voice prompt operation process.

The logic for the four keys in normal operation is as follows:

firstly, an operator above the strop presses a 'wakeup' button A, and equipment above the strop plays 'waiting for equipment below to answer'. When the device below the sliding rope receives the wake-up signal sent by the device above, the voice reports that the tourist above slides down and is ready.

And secondly, pressing a response button C by a worker below the strop, and playing a response by equipment below the strop and waiting for an upper response. And the equipment above the sliding rope receives a response signal sent by the equipment below, and then voice broadcasting is performed to 'the staff below is ready', and at the moment, the staff above the sliding rope starts to wear the safety equipment for the tourists.

And thirdly, the safety equipment is worn completely, when the worker above the safety equipment is separated from the hook, the upper equipment sends a gliding signal to the lower equipment, and meanwhile, the upper equipment broadcasts that the tourist has glided. Meanwhile, the lower device broadcasts the voice that the tourists on the upper side slide down and please prepare. If the top equipment does not receive the response signal of the second step, in the moment that the staff of top breaks away from the couple, then the top equipment constantly reports "below staff does not make preparation, does not slide", plays the warning effect, only closes the couple again, and voice broadcast just stops.

The logic of the four keys in abnormal operation is as follows:

(1) if the upper staff member has pressed the button a but the guest temporarily cancels the play, the upper staff member presses the "cancel" button B, and the operation cycle is cancelled. Simultaneously, the upper device and the lower device simultaneously broadcast the 'tourist temporarily cancel sliding' through voice, and the hook cannot be released.

(2) If the top staff pressed button A, the below staff also pressed button C and responded, but the below staff leaves in a hurried moment temporarily, then the below staff pressed "cancellation" button D, then the continuous voice broadcast of top equipment "below staff did not target in place, did not slide down", until the top staff pressed button B, and the couple can't be disengaged.

To sum up, the utility model discloses can effectively avoid the visitor be injured, improve the communication efficiency of standing on and standing off, standardize staff's operation. The magnetic device and the magnet arranged on the hook can effectively detect whether the hook is opened or closed. Both the upper station and the lower station are provided with a control box and a voice broadcasting device. The wireless communication is realized through stable loRa communication with the lower station in the upper station, realizes the interlock control of four buttons. The scheme has the advantages of simple structure, stability, reliability and easiness in installation, and can stably detect the operation state and send out voice prompt to ensure the safety and the standard of the sliding cable operation.

The foregoing is merely a preferred embodiment of the invention and various changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined by the appended claims.
