Example 1
Referring to fig. 1-7, the remote control transmitter 1 comprises a joystick 11, a display 12, an operation mode switch 13, an emergency stop button 17, a transmitting module 18, and a plurality of cruise path buttons (14-16). The course and the power of the unmanned ship are controlled by adopting double rockers; the display screen can display the speed and the position of the boat and the operation mode of the unmanned boat; an operation mode selector switch for selecting a remote operation or a control mode based on a portable terminal such as a computer; the panel of the remote controller emitter is provided with a plurality of cruise path keys, and the unmanned boat can realize autonomous cruise of a preset path through the keys in a remote control mode; the emergency stop key can force the unmanned boat to stop suddenly under emergency conditions, so that accidents are prevented; meanwhile, a plurality of keys are reserved on a panel of the remote controller emitter, and a user can train a path as required and store the path to an industrial personal computer to realize autonomous path planning. The remote controller receiver 2 is provided with a wireless receiving module 21 and a relay control board, when a corresponding key of the remote controller transmitter is pressed down, the corresponding relay 22 is closed after the receiver receives a signal, and the signal is output to the signal acquisition card.
The manual cruise of the unmanned ship is realized by using a remote controller rocker or an intelligent unmanned ship control system (RUB) interface as shown in figure 6, the course and the speed of the unmanned ship are in direct proportion to the push angle of the rocker in a remote control mode, a mouse is used for clicking a power button and a direction button under the control of the RUB to adjust, the time for pressing the button determines the running time of the unmanned ship, and the ship stops after the mouse is loosened, so that accidents caused by unstable communication can be prevented.
The autonomous cruise control modes of the unmanned ship are two, and are realized through a remote controller and a portable mobile terminal provided with an RUB, and the software architecture of an intelligent unmanned ship control system (RUB) adopts a hierarchical architecture idea; as shown in fig. 8, the layers communicate with each other via an interface. Similar to the physical model of the OSI7 layer, the device interface layer is equivalent to a hardware layer, the presentation layer is equivalent to an application layer, the service layer is equivalent to a server, and a plurality of hosts can commonly serve the presentation layer by adopting a cluster form; the presentation layer can not directly control the equipment interface layer, the service provided by the service layer is required to be called, the bottom protocol layer provides a protocol for the service layer, the lower layer provides service for the upper layer at the same level, and the presentation layer only needs to concern the logic details of the application program, but not the transmission activity of data in the network. The presentation layer and the three layers below it handle the real communication details. An unmanned ship intelligent control system (RUB) realizes the fusion of different operation system architectures through a shared bottom end protocol (mqtt, tcp), and realizes the multi-terminal synchronous control in the modes of web, APP, client and the like.
1. The autonomous cruise under the operation mode of the unmanned ship remote controller does not need any portable equipment or mobile phone to carry out complicated operation, simultaneously avoids the uncertainty of a cruise path, and enables users with lower cultural degree to operate; the control method comprises the following steps:
(1) A user trains under an RUB autonomous cruise mode according to actual application requirements to obtain an optimal cruise path, the optimal path is stored as a txt file, if a plurality of task scenes exist, a plurality of paths are trained, and corresponding path information is stored as files, such as cruise paths 1,2 and 3.
(2) And an operation mode switch of the remote controller emitter is switched to a remote control end, a corresponding cruise path is selected according to the cruise task, and a key corresponding to the path on a panel of the remote controller emitter is pressed. The key 1 corresponds to the cruise path 1, the key 2 corresponds to the cruise path 2, and so on.
(3) When the key 1 is pressed down, after the remote controller receiver receives a signal, the corresponding relay 1 on the relay control panel is closed, the closing signal is transmitted to a signal acquisition card of the shipborne industrial personal computer, the signal acquisition card is connected with the shipborne industrial personal computer or directly connected with the shipborne computer control panel through a 232 serial port, and an instruction of the signal acquisition card is sent to the industrial personal computer or the computer control panel.
(4) And after receiving the instruction, the intelligent unmanned ship control system on the industrial personal computer calls the cruise path 1, and further controls the unmanned ship to autonomously cruise according to the path 1 trained in advance. Similarly, when the cruise keys 2 and 3 are pressed, the unmanned boat travels along the cruise paths 2 and 3.
As shown in fig. 7, autonomous cruising of the unmanned ship in the mode of the portable mobile terminal based on the RUB includes two modes, namely a computer control mode and a main control panel control mode, wherein the computer control mode means that the portable mobile terminal provided with the RUB sends a cruising path to a shipborne industrial personal computer, and the industrial personal computer sends a control instruction to a computer control panel through a serial port 1 after receiving information, so as to control the unmanned ship to autonomously cruise according to the path set by the RUB; the control panel mode means that the computer control panel is directly connected and communicated with the portable mobile terminal provided with the RUB without passing through a shipborne industrial personal computer. The computer control mode is stable in communication, so this mode is preferred. The control method comprises the following steps:
(1) The RUB software interface of the portable computer control end is selected by computer control and mainboard control, and computer control is selected.
(2) During autonomous cruise, as shown in fig. 7, a navigation route is determined, the navigation route is split into a plurality of intermediate points (1,2,3,4,5 in fig. 7), the points are sequentially clicked on an RUB map by a mouse, specific longitude and latitude values can also be input to determine the points, after the points are clicked, a cruise adding button is sequentially clicked, a cruise point is added to a cruise list, and then cruise is clicked to realize autonomous cruise.
(3) In the autonomous cruise, a 'clear cruise' button needs to be clicked when a cruise point needs to be changed, deleted or added, at the moment, the ship stops, and the cruise path is set at the moment.
The control method can also be operated on a mobile phone, the specific operation method is the same as the operation mode of the RUB based on the computer, when automatic cruise is realized on the APP with the mobile phone, firstly, cruise route points are selected on a map, an optimal cruise route is obtained through a fitting algorithm, and the autonomous cruise can be started by clicking the cruise.
The control authorities of the mobile phone and the computer have an interlocking function, and when the unmanned boat is controlled by the RUB based on the computer, the mobile phone cannot control the unmanned boat; on the contrary, when the unmanned ship is under the control of the mobile phone APP, the computer RUB can only wait for the release permission of the mobile phone control end when the unmanned ship wants to acquire the control permission, so that the safety can be improved, and the occurrence of accidents caused by manual misoperation can be reduced.
Before the remote controller autonomously cruises, an optimal cruise path is trained in an RUB autonomous cruise mode, the path is saved as a txt file, and a plurality of paths and files such as cruise paths 1,2 and 3 can be saved. The path training method for autonomous cruising of the remote controller comprises the following steps:
firstly, planning a rough path according to the task requirement of an operation scene, selecting a cruise path point on an autonomous cruise map of a computer RUB or a mobile phone APP, clicking a cruise button, and issuing a cruise command to a shipborne industrial personal computer by a server. The cruise command format between the server and the industrial personal computer is as follows:
CRUISEx:(*DEV,dstID,srcID,CRUISEx；n；LAT1；LNG1；LAT2；LNG2；LAT3；LNG3...,CHK#)
wherein, n: the number of cruise points; x: a cruise path planning sequence number; LAT1; LNG1; the longitude and latitude of a first cruise point; LAT2; LNG2; the longitude and latitude of the second cruise point; … …
X =1,2,3 in CRUISEx respectively represents cruise route plan serial numbers. CRUISE1: a first cruise order number, a cruise path plan order number one; CRUISE2: a second cruise order number, cruise route plan order number two; CRUISE3: the third cruise order number, cruise route plan order number three.
The CRUISE commands CRUISE1, CRUISE2 and CRUISE3 correspond to three switching values of the remote controller, namely three CRUISE keys. After receiving CRUISE commands of CRUISE1, CRUISE2 and CRUISE3, the shipborne industrial personal computer stores or updates CRUISE points, analyzes the CRUISE commands and then sends control commands to the shipborne computer control main board to further control the unmanned ship to run according to the planned path
The operation and control of the unmanned ship under the remote controller mode comprise a remote controller, a signal acquisition card, an industrial personal computer, a computer control panel, a motor control panel and a motor, wherein the signal acquisition card can convert a high-level trigger switching value input signal into RS232/RS485 output, a communication protocol of the signal acquisition card and the shipborne industrial personal computer adopts a self-defined communication protocol, and the protocol format is as follows: 9600-N-8-1, the serial port baud rate is 9600, a check bit None, 8 data bits and 1 stop bit, and the hexadecimal representation is adopted. The communication command contains a total of 6 bytes, where 00 is the default address of the signal acquisition card. The shipborne industrial personal computer receives the command: AA5A 00 FC 0F FF, the control is not performed; receiving AA5A 00 FC xF FF, x =8, 4 and 2, which respectively represent that the cruise buttons 1,2 and 3 are pressed; the AA5A 00 FC 1F FF command indicates an emergency stop button press; the shipborne industrial personal computer sends a command: AA5A 00 FC 00 FF looks up the switching value status.
The signal acquisition card can report the switching value state actively, namely the signal acquisition card automatically uploads the switching value state to a shipborne industrial personal computer after detecting the switching value change, and the switching value is not uploaded as long as the change is realized no matter whether the high level of the switching value is detected to be changed to be low level or the low level is detected to be jumped to be high level. For example, when no key is pressed on the panel of the emitter of the remote controller, the switching value is not changed, and the signal acquisition card does not upload commands; when the emergency stop button on the panel of the remote controller emitter is dialed up to the upper part, the signal acquisition card actively sends a command: the AA5A 00 FC 1F FF is used for analyzing an emergency button press by the industrial personal computer according to a protocol analysis command, and then sending a command to the computer drive plate to control the unmanned ship to stop; when the emergency button is dialed to the original position, the signal acquisition card actively sends a command: AA5A 00 FC 0F FF, the industrial personal computer analyzes the emergency button according to the protocol and dials the emergency button to be suspended, the industrial personal computer does not issue instructions to the computer drive plate, and the unmanned ship maintains the original state.
The shipborne industrial personal computer can also actively inquire the switching value state, namely, an inquiry command is sent to the signal acquisition card: AA5A 00 FC 00 FF actively inquires the state of the switching value, and when the switching value is not closed, namely when a cruise key on a panel of a transmitter of the remote controller is not shifted, a relay corresponding to a receiver of the remote controller is switched off, the signal acquisition card returns to the shipborne industrial personal computer: AA5a 00 FC 0F FF, at which point the onboard industrial computer does not invoke the cruise path. When a cruise key 1 on a panel of a remote controller transmitter is pulled towards the X-axis direction, a remote controller receiver is closed corresponding to a relay 1, a high-level trigger switching value is input into a signal acquisition card, and the signal acquisition card sends a command to a shipborne industrial personal computer: and the AA5A 00 FC 8F FF, the shipborne industrial personal computer analyzes the received command according to the communication protocol and calls the cruise path 1, the command is sent to the computer drive board through serial port communication, and the unmanned ship is further controlled to autonomously cruise according to the path 1 trained in advance. Similarly, if the industrial personal computer receives a command: AA5A 00 FC 4F FF and AA5A 00 FC 2F FF indicate that the cruise keys 2 and 3 are pressed, and thus call the paths 2 and 3 to cruise. When the cruise keys 1,2 and 3 on the panel of the emitter of the remote controller are dialed to the original position, the signal acquisition card actively sends a command: and AA5A 00 FC 0F FF is sent to the shipborne industrial personal computer, the industrial personal computer does not issue instructions to a computer control board, the unmanned ship still cruises according to the previous path, and corresponding buttons are required to be shifted when the unmanned ship is stopped or the cruise route is changed.
