[0026] The beneficial effects of the present application are:

[0027] The present application provides a ship master clock system, which includes a driver console master clock, a central console master clock and a backup central console master clock connected through a CAN network for information interaction, the hardware and software structures of each master clock are the same, and each master clock includes a core processing module, an interface module, a clock handle, a gear transmission device, a potentiometer, a clock lamp plate and a buzzer, and each master clock can set the system part node, so that it is suitable for any operating part in the driver console, the central console or the backup central console, to realize the universal interchange of the corresponding master clock between the three operating parts. In this way, the master clocks of different operating parts (such as the driver console, the central console or the backup central console) can be used interchangeably, and the operator can choose the most suitable operating position according to the actual situation, which increases the flexibility and adaptability of the system; if a console has a problem, the operation can be quickly transferred to another available console without the need for complex reconfiguration process, which helps to ensure that the system can maintain operation even in fault conditions, improves the reliability and safety of the system; universal interchangeability means that no specific parts are needed when repairing or replacing components, and any standard node can be used for replacement, which reduces maintenance costs and shortens repair time; it can also allocate resources more effectively, optimize resource utilization and avoid unnecessary repeated investment; the universal interchange design allows faster switching from one operating part to another, thereby speeding up the response to emergencies.

[0028] The CAN network interface receives the gear specification setting message and transmits it to the core processing module. The core processing module sets the main clock gear specification state according to the gear specification setting message, and then replaces the corresponding lamp plate mask and step positioning component under the gear specification. The core processing module collects and processes the potentiometer value of the gear where the clock handle with the replaced step positioning component is located, and outputs the gear order current signal to the remote control system. When changing gears, only the lamp plate mask and the step positioning component corresponding to the gear need to be replaced, without the need to customize a complete set of clock handle hardware and write adaptive software. The clock handle with the replaced step positioning component drives the gear transmission device to make corresponding changes, and the potentiometer converts the changes of the gear transmission device into a potentiometer value input to the interface module, i.e. the core processing module collects and processes the potentiometer value of the gear where the clock handle with the replaced step positioning component is located. According to the potentiometer value and the order current mapping table, the potentiometer value obtained from the interface module is converted into the order current and output to the remote control system to control the gear change of the mechanical components. For example, two potentiometer value and order current mapping tables can be provided in the main clock system. The first potentiometer value and order current mapping table matches the first gear specification (e.g. five forward and three backward), and the second potentiometer value and order current mapping table matches the second gear specification (e.g. ten forward and five backward). When the main clock needs to change from the first gear specification to the second gear specification, the clock lamp plate mask and the step positioning component that meet the second gear specification are replaced first, and then the CAN setting software is used to send the gear specification setting message to the interface module. After the core processing module receives the gear specification setting message from the interface module, the second potentiometer value and order current mapping table is used to process the conversion between the potentiometer value and the order current. In this way, the problem of needing to customize a complete set of clock handle hardware and write adaptive software when the main clock changes gear specifications is solved. The application only needs to replace the clock lamp plate mask and the step positioning component that match the gear specification, and then send a command, which is simple and efficient.

[0029] When the control part of the remote control system is switched among the pilot console, the central console and the backup central console, the orders are communicated through the CAN network interface, and the core processing module of each master clock determines the light-emitting orders of the indicator light and the buzzer state according to the judgment processing rules of whether the potentiometer is disconnected and whether the handshaking communication is normal, and then sends the order signal to the remote control system. Thus, the application provides an efficient data transmission and processing method, so that the control signal can be quickly transmitted between each operating part, ensuring the timeliness and accuracy of the response, and the core processing module of each master clock can make decisions according to the current operating part and the effective response part (such as the current control part being the pilot console, the current effective response part being the central console; or the current control part being the pilot console, the current effective response part being the backup central console; or the current control part being the central console, or the current control part being the backup central console, etc.), ensuring the correct transmission of the order. When switching the control part, the core processing module will confirm the effectiveness of the new control source according to a series of judgment rules, avoiding illegal or unsafe control sources taking over the system. This mechanism adds an additional safety layer, which is particularly important in critical applications such as ship equipment. And the logic processing of the master clock of different operating parts when switching the control part is considered, so that the universality and interchangeability can be achieved when debugging or replacing equipment, and the number of spare parts can be reduced.

[0030] The ship master bell system provided by the application can be applied to the driving console, the centralized console and the standby centralized console, and system part node setting is realized through a CAN network interface or a USB interface. The USB interface needs to complete enabling setting, and the CAN network interface does not need to complete enabling setting. The master bell system receives bell part setting messages, bell part query messages, system node setting messages, system node query messages and general management setting messages through the CAN network interface, and receives USB enabling, bell part query messages, USB enabling and bell part setting messages, system node setting messages, system node query messages and general management setting messages through the USB interface. Through application part information and node information setting of the master bell of different operation parts, the master bell can identify its operation part, and when the master bells of different operation parts communicate with each other, the application part name and node information carried in the communication message can be used to identify the source of the message, so that corresponding processing can be performed. Meanwhile, the master bell application part information and node information are carried when the remote control system sends messages to each master bell, so that the master bell receiving the message can judge the part to be operated by the remote control system based on the master bell application part information and node information. Meanwhile, the master bells of the three operation parts have universality and interchangeability because the hardware and software (i.e. the working processing logic of the core processing module) of the master bells of the three operation parts are the same.

[0031] The ship master bell system can provide interfaces and information for a computer to record handle operation of each master bell and meet the unified light adjustment requirement of the ship system on the bridge related equipment. In addition, the master bell system designs online calibration functions and module level fault alarm functions for easy operation, which facilitates the use and fault diagnosis of debugging service personnel and users.

[0032] The application sends the bell value and the running state information of the master bell to the computer at a fixed time, so that the computer can record the handle operation of the master bell and the running state information of the master bell. In this way, the bell value and the running state information of the master bell of the ship can be recorded in time, information loss caused by manual recording is prevented, and later viewing and maintenance are more convenient.

[0033] The application provides two light adjustment modes of network light adjustment and current light adjustment, and sets priorities, switching of network light adjustment and current light adjustment and light adjustment calculation logic. In this way, when one light adjustment mode fails, the other light adjustment mode can provide light adjustment function support in time.

[0034] The application provides online calibration functions, which can complete calibration of a potentiometer input, calibration of a bell current output and calibration of a light adjustment current input during normal operation of the ship. In this way, data calibration can be completed in time when gear recognition is inaccurate, a bell signal is abnormal and light adjustment is abnormal, so that gear recognition, a bell signal and light adjustment are not abnormal.

[0035] The application provides a fault query function, and the remote control system can send a message to the master clock system to query whether the master clock system has a fault.

[0036] The application also provides a fault alarm function, and the master clock system sends a fault feedback message to the computer at regular time intervals, and sends different fault feedback message contents under different judgment logics, including sending a CAN communication fault state, a USB communication fault state, a potentiometer disconnection fault state and a comprehensive fault state under different conditions. In this way, the computer can record the CAN communication fault state and the potentiometer disconnection fault state of the master clock system in time, and provide support for subsequent fault query diagnosis.

Through the application part information and node information setting of the main clock of different operating parts, the main clock can identify its operating part, and when the main clocks of different operating parts communicate with each other, the application part name and node information carried in the communication message can be used to identify the source of the message, so as to make corresponding processing. At the same time, the remote control system carries the main clock application part information and node information when sending messages to each main clock, so that the main clock receiving the message can judge the part to be operated by the remote control system based on the main clock application part information and node information. Among them, the USB interface needs to complete the enablement setting, and the CAN network interface does not need to complete the enablement setting.

Two kinds of potentiometer value and order current mapping tables can be provided in the main bell system. The first kind of potentiometer value and order current mapping table matches the first kind of gear specification (such as advancing five and retreating three), and the second kind of potentiometer value and order current mapping table matches the second kind of gear specification (such as advancing ten and retreating five). When the main bell needs to change from the first kind of gear specification to the second kind of gear specification for use, the bell lamp panel mask and the step positioning component conforming to the second kind of gear specification are replaced first, and then the CAN setting software is used to send the gear specification setting message to the interface module. After the core processing module receives the gear specification setting message from the interface module, the second kind of potentiometer value and order current mapping table is used to process the conversion between the potentiometer value and the order current. At the same time, the embodiment of the application can also provide a gear specification query function. After the main bell receives the gear specification query message, a feedback message of the gear specification state is sent according to the currently used gear specification.

[0054] Preferably, the console main clock of the embodiment has a light adjusting function, and is provided with two modes of network light adjusting and current light adjusting, and the priority of the network light adjusting mode is higher than that of the current light adjusting mode, so that when one light adjusting mode fails, the other light adjusting mode can provide light adjusting function support in time. When the main clock receives comprehensive light adjusting information of the unified light adjusting device of the cab through the CAN network interface, the console main clock directly converts into the network light adjusting mode to adjust the light of the console main clock under the control of the core processing module; when the main clock does not receive the comprehensive light adjusting information of the unified light adjusting device of the cab for more than a preset time threshold (for example, 6 seconds, 7 seconds or 8 seconds, etc.), and the change of the received light adjusting current signal input exceeds a preset current threshold (for example, 28%, 30% or 32%, etc.), the console main clock converts into the current light adjusting mode to adjust the light of the console main clock under the control of the core processing module. When the console main clock is in the network light adjusting mode, the core processing module thereof adjusts according to the contents of the light adjusting mode switching message, the intra-zone mode and brightness synchronization message, the intra-zone device mode and brightness inquiry message, the zone unified brightness increment adjusting message and the test light message sent by the unified light adjusting device of the cab; wherein the console main clock receives the light adjusting mode switching message, and adjusts the light of the cab to the corresponding preset light effect according to the content of the message; the console main clock receives the intra-zone mode and brightness synchronization message, and determines the light adjusting output level according to the content of the message to adjust the light of the specified area; the console main clock receives the intra-zone device mode and brightness inquiry message, and sends the light adjusting feedback message, the content of which includes the brightness level, the brightness change direction and the brightness change level, etc.; the console main clock receives the zone unified brightness increment adjusting message, determines the light adjusting output level according to the brightness change direction and the brightness change level, and sends the light adjusting feedback message according to the sending frequency requirement (for example, 0.5 Hz, 1 Hz or 2 Hz, etc.), the content of which includes the brightness level, the brightness change direction and the brightness change level, etc.; the console main clock receives the test light message, enters the test light mode, displays all gear order indicator lights, and automatically exits the test light mode after a certain time (for example, 6 seconds, 7 seconds or 8 seconds, etc.) to restore the display of the order indicator light of the corresponding gear; when the console main clock is in the current light adjusting mode, the core processing module thereof adjusts according to the light adjusting current input, calculates by using the light adjusting current input calibration parameter to determine the light adjusting output level; and the core processing module of the console main clock calculates by using the light adjusting output level and the light adjusting curve segment parameter to output the light adjusting signal.

[0055] Preferably, the preset light effect can be set according to the use scene, and the value of the preset time threshold is not limited in the embodiment, for example, it can be a daytime mode, a dawn and dusk mode or a night mode, etc.

[0056] Preferably, the light adjusting curve segment parameter can be the corresponding relationship parameter of the light adjusting input level and the light adjusting signal.

[0057] Preferably, the dimming current input calibration parameter may be a comparison table of dimming current input and dimming output level.

[0058] Preferably, the master car clock completes the parameter calibration of each master car clock through the CAN network interface (which can be a calibration message sent by the CAN setting software or the remote control system), including the potentiometer input parameter calibration, the vehicle command current output parameter calibration and the dimming current input parameter calibration.

[0059] Among them, the potentiometer input parameter calibration: the main vehicle clock receives the potentiometer input upper limit record message, the potentiometer input lower limit record message, and the potentiometer input record reading message. When the main vehicle clock receives the potentiometer input upper limit record message, the potentiometer value when the vehicle clock handle is pushed to the maximum gear (such as "advance five" or "advance ten", etc.) is recorded to obtain the maximum potentiometer value (that is, the potentiometer value corresponding to the maximum gear); when the main vehicle clock receives the potentiometer input lower limit record message, the potentiometer value when the vehicle clock handle is pushed to the minimum gear (such as "backward three" or "backward five", etc.) is recorded to obtain the minimum potentiometer value (that is, the potentiometer value corresponding to the minimum gear); after the main vehicle clock receives the potentiometer input record reading message, the potentiometer input parameter calibration is completed according to the recorded maximum potentiometer value and the minimum potentiometer value and the gear specification currently in use.

[0060] Calibration of vehicle current output parameters: The main vehicle clock receives the vehicle current output survey message and the vehicle current output survey completion message, and uses the content data corresponding to the vehicle current output survey message corresponding to different vehicle currents measured by a multimeter to complete the calibration of the vehicle current output parameters.

[0061] For example, in the embodiment of the present application, the multimeter can be adjusted to the current measurement position, and the main car clock car command current output interface is connected to the multimeter according to the electrical wiring diagram, and then the CAN setting software or remote control system is used to send the car command current output survey message to the main car clock, and the main car clock enters the car command current output survey mode. The car command current output signal of the main car clock is adjusted by sending the car command current output survey message containing different calibration data multiple times, and the measured value of the multimeter is observed, and the calibration data corresponding to the car command current output survey message when the measured value of the multimeter is the first current (such as 4 mA) and the second current (such as 20 mA) are recorded respectively. Subsequently, the CAN setting software or remote control system is used to send the car command current output survey end message to the main car clock, and the main car clock exits the car command current output survey mode. Finally, the master car clock receives the car command current output calibration message sent by the CAN setting software or the remote control system, indicating that the calibration data recorded above is used for calibration, and completes the calibration of the car command current output parameters based on the calibration data corresponding to the minimum input current first current and the calibration data corresponding to the maximum input current second current.

[0062] Dimming current input parameter calibration: The master car clock receives different dimming current input calibration messages, uses a signal generator for signal input, and completes the dimming current input parameter calibration.

[0063] For example, in the embodiment of the present application, the signal generator is adjusted to the current output mode, and the main vehicle clock dimming current input interface is connected to the signal generator in accordance with the electrical wiring diagram. The signal generator is used to transmit a third current (such as 4 mA) dimming current signal to the main vehicle clock, and at the same time, a dimming current third current input calibration message (which can be a dimming current 4 mA input calibration message) is sent to the main vehicle clock, and the calibration data corresponding to the third current dimming current signal is recorded; the signal generator is used to transmit a fourth current (such as 20 mA) dimming current signal to the main vehicle clock, and at the same time, a dimming current fourth current input calibration message (which can be a dimming current 20 mA input calibration message) is sent to the main vehicle clock, and the calibration data corresponding to the fourth current dimming current signal is recorded; finally, the main vehicle clock completes the calibration of the dimming current input parameters based on the calibration data corresponding to the third current dimming current and the calibration data corresponding to the fourth current dimming current.

[0064] The present embodiment provides an online calibration function that can complete the calibration of potentiometer input, vehicle command current output, and dimming current input during normal ship operation. This allows timely data calibration when gear position recognition is inaccurate, vehicle command signals are abnormal, or lighting adjustment is abnormal, ensuring that gear position recognition, vehicle command signals, and lighting adjustment are correct.

[0065] Preferably, the master car clock receives a fault query message (CAN fault request message) sent by the remote control system or CAN setting software, and the core processing module sends a fault feedback message (CAN fault feedback message) to the remote control system or CAN setting software based on the status of each master car clock. The content of the fault feedback message includes CAN communication fault status, USB communication fault status, potentiometer disconnection fault status, and comprehensive fault status. Specifically, the core processing module makes a judgment based on the master car clock's CAN heartbeat message, vehicle command information CAN message, and CAN feedback message transmission status. If there is an abnormal message transmission status, the fault feedback message sent includes the CAN communication fault status. The core processing module makes a judgment based on the USB connection status and USB message reception status. If there is an abnormal communication status, the fault feedback message sent includes the USB communication fault status. The core processing module makes a judgment based on the potentiometer connection status. If the potentiometer is disconnected, the fault feedback message sent includes the potentiometer disconnection fault status. The core processing module makes a comprehensive judgment based on other fault statuses in the message and sends a fault feedback message including the comprehensive fault status.

[0066] Preferably, the master clock timing sends a fault feedback message (USB fault feedback message) to the computer, wherein the content of the fault feedback message includes the integrated fault state, the CAN communication fault state, and the potentiometer disconnection fault state. Specifically, the core processing module judges according to the CAN heartbeat message, the order information CAN message, and the CAN feedback message sending state of the master clock. If there is an abnormal message sending state, the CAN communication fault state is included in the fault feedback message. The core processing module judges according to the potentiometer connection state. If the potentiometer is disconnected, the potentiometer disconnection fault state is included in the fault feedback message. The core processing module comprehensively judges according to other fault states in the message and sends the integrated fault state included in the fault feedback message. In this way, the computer can record the CAN communication fault state, the potentiometer disconnection fault state, etc. of the master clock system in time, and provide support for subsequent fault query and diagnosis.

[0067] The configuration mode of the ship master clock system of the embodiment of the present application can have two modes, one is a two-clock mode, and the other is a three-clock mode. The two-clock mode includes a driver console master clock (order issuing part) and a control console master clock (order receiving part). The three-clock mode includes a driver console master clock (order issuing part), a control console master clock (order receiving part 1), and a standby control console master clock (order receiving part 2).

[0068] The control part of the remote control system can be switched among the driving control room, the central control console and the standby central control console. The remote control system can send system control information messages to the main telegraph for remote operation. The message content includes the current control part of the system, the buzzer control instruction. The main telegraph can drive the buzzer according to the buzzer control instruction (including the remote control buzzer control instruction and the telegraph buzzer control instruction). When the control part of the remote control system is switched among the driving control room, the central control console and the standby central control console, the car order communication of the main telegraph of each operating part is carried out through the CAN network interface. The core processing module of each main telegraph determines the car order indication (acoustic and optical indication) and the buzzer state (ringing or not) of the indicator light with the replaced lamp panel mask according to the judgment processing rules of the several conditions of the driving control room, the central control console and the standby central control console as the current control operating part and the effective return order part, the state of whether the potentiometer is disconnected and whether the handshaking communication is normal. When the main telegraph potentiometer is normal and the car order changes when the telegraph handle is pushed, the car order information CAN message is sent once for the main telegraph of other operating parts. Each main telegraph receives the car order information CAN message sent by the main telegraph of other operating parts according to the system part node setting, and the communication state is judged by the core processing module according to the message receiving condition. The present application provides an efficient data transmission and processing mode, so that the control signal can be quickly transmitted between each operating part, ensuring the timeliness and accuracy of the response. The core processing module of each main telegraph can quickly make a decision according to the current operating part and the effective return order part, ensuring the correct transmission of the order. When the control part is switched, the core processing module will confirm the effectiveness of the new control source according to a series of judgment rules, avoiding illegal or unsafe control source taking over the system. This mechanism adds an additional safety layer, which is particularly important in critical applications such as ship equipment. And the logic processing of the main telegraph of different operating parts when the control part is switched is considered, so that universality and interchangeability can be achieved when debugging or replacing equipment, and the number of spare parts can be reduced.

[0069] Among them, the core processing module of each main telegraph determines the car order indication and buzzer state of the indicator light with the replaced lamp panel mask according to the judgment processing rules of the several conditions of the driving control room, the central control console and the standby central control console as the current control operating part and the effective return order part, the state of whether the potentiometer is disconnected and whether the handshaking communication is normal. The judgment processing rules in the following tables 1-4 are listed as follows.

[0070] For example, as shown in Table 1, the driving control room-central control console car order processing table, when the current control part of the remote control system is in the driving control room (the order part is the driving control room) and the current effective return order part is in the central control console, the car order processing is as follows:
