Detailed Description

The following is a detailed description of the present invention with reference to the drawings of the remote control device.

A remote control device comprises a remote control transmitting device and a remote control receiving device;

the remote control transmitting device is used for transmitting a remote control signal, and the remote control receiving device is used for receiving the remote control signal; the remote control transmitting device and the remote control receiving device are in communication connection through a medium transmission communication module; the method is characterized in that:

the remote control receiving device is provided with a near field communication module which is used for being in communication connection with the near field communication module arranged on the carrier for execution.

In practice, the carrier is also loaded with an execution control module (for controlling the execution module (e.g. ignition and eventually working by chemical force) or an execution mechanism (e.g. a mechanical manipulator working by mechanical force; also e.g. a sea-bottom buoy or underwater Robot (ROV); also e.g. an underwater vehicle)), which is in communication connection with a near field communication module mounted on the carrier.

It will be appreciated by those skilled in the art that the remote control receiving device of the above described remote control device is located within a distance from the carrier that the near field communication module is able to communicate with before being assembled for use.

Compared with the prior art, the remote control device has the advantages that:

firstly, smooth completion of underwater operation can be better ensured

The remote control receiving device and the carrier are in communication connection through the near field communication module, so that the carrier can transmit control signals to corresponding actuating mechanisms on the remote control receiving device (for example, the actuating mechanisms are releasing mechanisms for releasing buoys (which float on the water surface to play a role in prompting or receiving and sending aerial radio signals), or the actuating mechanisms are self-checking prompting mechanisms (which are used for ensuring the respective states of the remote control receiving device and the carrier and whether the communication between the remote control receiving device and the carrier is normal)) -visible, the remote control device can easily realize rich functions (for example, the carrier triggers the self-checking of the remote control receiving device, and the remote control receiving device sends self-checking indication signals), thereby ensuring the reliability of the states and the executing functions of each device and ensuring the successful and reliable completion of underwater operation.

Therefore, the remote control device adopting the technical scheme can preferentially send a control signal by the carrier to control the action of the corresponding executing mechanism on the remote control receiving device and serve as the basis of subsequent remote control; meanwhile, whether the near field communication module of the carrier and the near field communication module of the remote control receiving device are normal or not is judged, and the fact that subsequent remote control signals can be reliably sent to the carrier by the remote control transmitting device is guaranteed.

Secondly, the operation is more convenient and safer to use and can be more timely, efficient and safer

In the prior art, a carrier adopts a wired cable, and the wired cable is easy to limit the arrangement mode and the arrangement distance of the carrier; and the carrier cloth and the carrier are usually not the same person (or object), so that timely, efficient and safe underwater operation is difficult to implement.

According to the technical scheme, rapid underwater cloth can be directly carried by an operator (diver) with the remote control device and the carrier, and cloth points and cloth distances are more independent and flexible. After the carrier is arranged in place, an operator is far away from the carrier and reaches a certain safe distance, and the carrier can be controlled in time through the remote control transmitting device, so that the carrier is more convenient, efficient and safe to use.

And the carrier is in communication connection (wireless connection) with the remote control receiving device through the near field communication module, so that the remote control receiving device is conveniently and safely and rapidly detached from the carrier (the wired cable is difficult to detach in the conventional wired cable mode), the carrier is prevented from being started accidentally, and the safety of operation is effectively ensured.

The near field communication module is any one of a Bluetooth module, an NFC module or an optical communication module.

The frequency range of the NFC module is 300 kHz-300 GHz, wherein signals of several MHz frequency bands have better environmental noise influence resistance and higher information transmission rate underwater, and the reliability of near field communication can be ensured.

The Bluetooth module is an underwater Bluetooth module (English of the underwater Bluetooth module is seatoth, and the underwater Bluetooth module is not described in detail in the prior art), the propagation speed of the underwater Bluetooth module in water is 100kbps, and the maximum communication distance can reach 10 m.

The optical communication module is an underwater optical communication module, the underwater optical communication module performs underwater communication by using optical signals with blue-green wavelength, and if bidirectional communication is to be realized between the underwater optical communication modules, each underwater optical communication module comprises an optical transmitter and an optical receiver 31. The underwater optical communication module is the prior art and is not described herein.

The near field communication module can realize underwater communication, and can ensure smooth realization of a remote control function.

Wherein the medium transmission communication module is a radio communication module; the remote control receiving device comprises a receiver 31 and a buoy provided with an antenna, and the receiver 31 and the antenna of the buoy form wired communication connection through a communication cable; the buoy is connected to the receiver 31 by a controllable release mechanism.

The radio communication module transmits signals through an air medium; the radio communication technology is mature and reliable, and is more beneficial to design, manufacture and use.

The remote control method of the remote control device comprises the following steps:

firstly, an execution control module in a carrier sends a release signal and transmits the release signal to a receiver 31 of a remote control receiving device through a near field communication module, and the receiver 31 of the remote control receiving device controls a release mechanism to release the buoy;

then, after the buoy floats to the water surface, a remote control signal sent by the remote control transmitting device is received through an antenna, and the remote control signal is transmitted to the remote control receiving device through a cable;

and finally, the remote control receiving device transmits a remote control signal to an execution control module in the carrier through the near field communication module.

The remote control method of the remote control device has the advantages of better ensuring the safety and reliability of operation, and specifically comprises the following steps:

firstly, the buoy can be released only after a carrier and a remote control receiving device are installed at a preset underwater position; after the buoy floats to the water surface, the wireless remote control signal transmitted by the air medium can be received (wherein, the release signal can be sent by an operator [ diver ] touching a control switch on the carrier, or the release signal is triggered by a timer or a water depth sensor on the carrier).

Secondly, only after the buoy floats to the water surface and the operator carries the remote control transmitting device to the water surface, the radio remote control signal can be transmitted to the antenna on the buoy through the remote control transmitting device (by using an air medium), and then the remote control signal can be transmitted to the remote control receiving device through the cable after the buoy receives the signal.

In conclusion, an operator cannot start the execution control module by misoperation in water, and the carrier cannot be controlled by an underwater interference signal before receiving no remote control signal; and then can be better guarantee that operating personnel keeps away from the carrier and just can remote control after the safe distance to ensure underwater operation's security.

According to the technical scheme, the operation and control time is determined by the operator, and compared with the scheme that the operation and control time is determined by other people, the operation and control method is safer for the operator.
