The priority of the network dimming mode is set higher than the current dimming mode. When the main clock receives the comprehensive dimming information of the unified dimming device in the cab through the CAN network interface, the main clock on the driving console is directly converted to the network dimming mode under the control of the core processing module to adjust the light of the main clock on the driving console;

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

[0027] The present invention provides a ship main clock system, including a main clock on a driving console, a main clock on a centralized control console and a main clock on a standby centralized control console, which are connected to each other via a CAN network for information exchange. The hardware and software structures of the main clocks are the same, and all include a core processing module, an interface module, a clock handle, a gear transmission device, a potentiometer, a clock light board and a buzzer. System location nodes can be set to make them suitable for any operating location in the driving console, the centralized control console or the standby centralized control console, so as to realize the universal interchange of the corresponding main clocks between the three operating locations. In this way, the main car clocks of different operating positions (such as the driving console, centralized control console or backup centralized control console) can be used interchangeably, and the operator can choose the most suitable operating position to work according to the actual situation, which increases the flexibility and adaptability of the system; if a problem occurs in one console, the operation can be quickly transferred to another available console without the need for a complicated reconfiguration process, which helps to ensure that the system can be maintained even in the event of a failure, thereby improving the reliability and safety of the system; universal interchangeability means that no specific parts are required when repairing or replacing components, and any node that meets the standards 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 duplication of investment; the universal interchangeable design allows faster conversion from one operating position to another, thereby speeding up the response to emergencies.

[0028] After receiving the gear specification setting message, the CAN network interface transmits it to the core processing module. The core processing module sets the gear specification state of the main car clock according to the gear specification setting message, and then replaces the corresponding light board mask and step positioning component under the gear specification. The core processing module then collects and processes the potentiometer value of the gear position of the car clock handle where the step positioning component has been replaced, and outputs the gear car command current signal to the remote control system. When changing the gear, it is only necessary to replace the light board mask and the step positioning component of the car clock handle corresponding to the gear position, without re-customizing the entire set of car clock handle hardware and writing adaptation software. The car clock handle that has been replaced with the step positioning component drives the gear transmission device to make corresponding changes. The potentiometer converts the change of the gear transmission device into a potentiometer value and inputs it into the interface module, that is, the core processing module collects and processes the potentiometer value of the gear position of the car clock handle where the step positioning component has been replaced, and according to the potentiometer value and car command current mapping table, the potentiometer value obtained from the interface module is converted into a car command current and output to the remote control system to control the gear change of the mechanical component. For example, two types of potentiometer values ​​and vehicle command current mapping tables can be provided in the main car clock system. The first type of potentiometer value and vehicle command current mapping table matches the first gear specification (such as five forward and three backward), and the second type of potentiometer value and vehicle command current mapping table matches the second gear specification (such as ten forward and five backward). When the main car clock needs to be changed from the first gear specification to the second gear specification for use, first replace the car clock light board mask and the stepped positioning component that meet the second gear specification, and then use the CAN setting software 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, it uses the second type of potentiometer value and vehicle command current mapping table to process the conversion between the potentiometer value and the vehicle command current. In this way, the problem of needing to re-customize the entire car clock handle hardware and write the adaptation software when the main car clock changes the gear specification is solved. The present application only needs to replace the car clock light board mask and the stepped positioning component that are adapted to the gear specification, and then send a command, which is simple and efficient to operate.

[0029] When the control part of the remote control system is switched between the driving console, the centralized control console and the standby centralized control console, the car order communication of the main car clock of each operating part is carried out through the CAN network interface, and the core processing module of each main car clock determines the car order indication and buzzer state of the indicator light of the replaced light panel mask according to the driving console, the centralized control console and the standby centralized control console as the current controlled operating part and the effective return order part according to the judgment and processing rules of whether the potentiometer is disconnected and whether the handshake communication is normal, and then sends the car order signal to the remote control system. In this way, the present invention provides an efficient data transmission and processing method, so that the control signal can be quickly transmitted between various operating parts, ensuring the timeliness and accuracy of the response, and the core processing module of each main car clock can make a decision quickly according to the current operating part and the effective return order part (for example, the current control part is the driving console, the current effective return order part is the centralized control console; or the current control part is the driving console, the current effective return order part is the standby centralized control console; or the current control part is the centralized control console, or the current control part is the standby centralized control console, etc.), to ensure the correct transmission of the command. When switching the control position, the core processing module will confirm the validity of the new control source according to a series of judgment rules, avoiding illegal or unsafe control sources from taking over the system. This mechanism adds an extra layer of safety, especially in critical applications such as ship equipment. And the logic processing of the main clocks in different operating positions when switching the control position is taken into account, so that universality and interchangeability can be achieved during fault debugging or equipment replacement, and the number of spare parts can also be reduced.

[0030] The ship main clock system provided by the present invention can be applicable to a driving console, a centralized control console and a backup centralized control console, and the system part node setting is realized through a CAN network interface or a USB interface. The USB interface needs to complete the enabling setting, and the CAN network interface does not need to enable the setting. The main clock system receives clock part setting messages, clock part query messages, system node setting messages, system node query messages, and general management setting messages through the CAN network interface, and receives USB enable and clock part query messages, USB enable and clock part setting messages, system node setting messages, system node query messages, and general management setting messages through the USB interface. By setting the application part information and node information of the master car clock at different operating parts, the master car clock can identify its own operating part, and when the master car clocks at different operating parts communicate with each other, the source of the message can be identified through the application part name and node information carried in the communication message, so as to make corresponding processing. At the same time, the remote control system carries the application part information and node information of the master car clock when sending messages to each master car clock, so that the master car clock that receives the message can judge the part to be operated by the remote control system based on the application part information and node information of the master car clock. At the same time, since the hardware and software (i.e., the working processing logic of the core processing module) of the master car clocks at these three operating parts are the same, the master car clocks at the three operating parts of the driving console, the centralized control console, and the standby centralized control console have universality and interchangeability.

[0031] The ship main engine clock system of the present invention can provide interfaces and information for the computer to record the handle operations of each main engine clock in real time and meet the unified dimming requirements of the ship system for the relevant equipment in the cab. In addition, the main engine clock system is designed with an easy-to-operate online calibration function and a module-level fault alarm function, which is convenient for debugging service personnel and users to use and diagnose faults.

[0032] The present invention sends the vehicle command value and the operating status information of the main vehicle clock to the computer at regular intervals, so that the computer can record the handle operation of the main vehicle clock and the operating status information of the main vehicle clock. In this way, the vehicle command value of the ship and the operating status information of the main vehicle clock can be recorded in time, and the information loss due to manual recording can be prevented, which is more convenient for later viewing and maintenance.

[0033] The present invention provides two lighting adjustment modes, network dimming and current dimming, and sets priority, switching between network dimming and current dimming, and dimming calculation logic, so that when one dimming mode fails, the other dimming mode can provide dimming function support in time.

[0034] The present invention provides an online calibration function, which can complete the calibration of the potentiometer input, the vehicle command current output, and the dimming current input during the normal operation of the ship. In this way, when the gear position recognition is inaccurate, the vehicle command signal is abnormal, and the light adjustment is abnormal, the data calibration can be completed in time to ensure that the gear position recognition, vehicle command signal, and light adjustment are normal.

[0035] The present invention provides a fault query function, and the remote control system can query whether the main car clock system has a fault by sending a message information to the main car clock system. In this way, the user can actively and timely check the status of the main car clock system when needed.

[0036] The present invention also provides a fault alarm function. The main car clock system sends fault feedback messages to the computer at regular intervals, and sends different fault feedback message contents under different judgment logics, including under what circumstances to send CAN communication fault status, USB communication fault status, potentiometer disconnection fault status and comprehensive fault status. In this way, the computer can timely record the CAN communication fault status and potentiometer disconnection fault status of the main car clock system, and provide support for subsequent fault query and diagnosis.

The core processing module then collects and processes the potentiometer value of the gear position of the car clock handle where the step positioning component has been replaced, outputs the gear car command current signal to the remote control system, and sends the car command information CAN message for the main car clock of other operating parts to use. Each main car clock receives the car command information CAN message sent by the main car clock of other operating parts that is paired with it according to the system part node setting, and each core processing module judges the communication status according to the message reception situation. In this way, the problem of needing to re-customize the entire car clock handle hardware and write the adaptation software when the main car clock changes the gear specification is solved. The present application only needs to replace the car clock light board mask and step positioning component that are adapted to the gear specification, and then send a command, which is simple and efficient to operate.

[0051] Specifically, the core processing module samples and filters the potentiometer value of the gear position of the car bell handle, and the filtering process includes median filtering, arithmetic mean filtering, etc. The core processing module judges the fault of the potentiometer disconnection and the gear position of the car bell handle according to the gear position specification and the potentiometer input calibration parameters, calculates the car command value corresponding to the gear position, and uses the car command value and the car command current output calibration parameters for calculation, and outputs the gear position car command current signal to the remote control system.

[0052] In the embodiment of the present application, each main clock can send a clock signal including a clock value and operating status information of the main clock parts to a computer at a regular interval (such as 200 milliseconds, 300 milliseconds or 400 milliseconds, etc.) to record the clock handle operation of each main clock. In this way, the ship's clock value and the operating status information of the main clock can be recorded in time to prevent information loss due to manual recording, which is more convenient for later viewing and maintenance.

[0053] When the gear position is changed in the embodiment of the present application, the car clock handle drives the gear transmission device to make corresponding changes, and the potentiometer converts the change of the gear transmission device into a potentiometer value and inputs it into the interface module, that is, the core processing module collects and processes the potentiometer value of the gear position of the car clock handle where the stepped positioning component has been replaced, and converts the potentiometer value obtained from the interface module into a car command current according to the potentiometer value and the car command current mapping table and outputs it to the remote control system to control the gear position change of the mechanical component. At the same time, the car command information is synchronized to the main car clock of other operating parts through the CAN communication interface, so that it can make corresponding processing. Two types of potentiometer value and car command current mapping tables can be provided in the main car clock system. The first type of potentiometer value and car command current mapping table matches the first gear position specification (such as five forward and three backward), and the second type of potentiometer value and car command current mapping table matches the second gear position specification (such as ten forward and five backward). When the main car clock needs to be changed from the first gear specification to the second gear specification for use, first replace the car clock light panel mask and the stepped positioning component that meet the second gear specification, and then use the CAN setting software 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, it uses the second potentiometer value and vehicle command current mapping table to process the conversion between the potentiometer value and the vehicle command current. At the same time, the embodiment of the present application can also provide a gear specification query function. When the main car clock receives the gear specification query message, it sends a feedback message of the gear specification status according to the currently used gear specification.

[0054] Preferably, the main car clock of the driving console in the embodiment of the present application has a dimming function, and is provided with two modes, namely, network dimming and current dimming. The priority of the network dimming mode is set higher than that of the current dimming mode. When one dimming mode fails, the other dimming mode can provide dimming function support in time. When the main car clock receives the comprehensive dimming information of the unified dimming device in the cab through the CAN network interface, the main car clock of the driving console directly switches to the network dimming mode under the control of the core processing module to adjust the light of the main car clock of the driving console; when the main car clock does not receive the comprehensive dimming information of the unified dimming device in the cab for more than a preset time threshold (such as 6 seconds, 7 seconds or 8 seconds, etc.), and the received dimming current signal input changes more than a preset current threshold (such as 28%, 30% or 32%, etc.), the main car clock of the driving console switches to the current dimming mode under the control of the core processing module to adjust the light of the main car clock of the driving console. When the main car clock of the driving console is in the network dimming mode, its core processing module makes corresponding adjustments according to the contents of the dimming mode switching message, the mode brightness synchronization message within the partition, the device mode and brightness inquiry message within the partition, the unified brightness increment adjustment message of the partition, and the test light message sent by the unified dimming device in the cab; among them, the main car clock of the driving console receives the dimming mode switching message, and adjusts the lights in the cab to the corresponding preset lighting effects according to the content of the message; the main car clock of the driving console receives the mode brightness synchronization message within the partition, and determines the dimming output level according to the content of the message, and dims the designated area; the main car clock of the driving console receives the device mode and brightness inquiry message within the partition, and sends a dimming feedback message, the content of which includes brightness level, brightness change direction and brightness change level, etc.; the main car clock of the driving console receives the unified brightness increment adjustment message of the partition The message determines the dimming output level according to the direction and level of brightness change, and sends the dimming feedback message according to the sending frequency requirement (such as 0.5 Hz, 1 Hz or 2 Hz, etc.), the content of which includes brightness level, brightness change direction and brightness change level, etc.; the main car clock on the driving console receives the test light message, enters the test light mode, displays the vehicle command indicator lights of all gears in flat light, and automatically exits the test light mode after a certain period of time (such as 6 seconds, 7 seconds or 8 seconds, etc.), and restores the display of the vehicle command indicator lights of the corresponding gears; when the main car clock on the driving console is in the current dimming mode, the core processing module makes corresponding adjustments according to the dimming current input, uses the dimming current input calibration parameters for calculation, and determines the dimming output level; the core processing module of the main car clock on the driving console uses the dimming output level and the dimming curve segmentation parameters for calculation, and outputs the dimming signal.

[0055] Preferably, the preset lighting effects can be set according to the usage scenario. The embodiment of the present application does not limit the value of the preset time threshold, for example, it can be a day mode, a twilight mode or a night mode.

[0056] Preferably, the dimming curve segmentation parameter may be a corresponding relationship parameter between the dimming input level and the dimming 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 main car clock completes the parameter calibration of each main 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 potentiometer input parameter calibration, car command current output parameter calibration and dimming current input parameter calibration.

[0059] Among them, the potentiometer input parameter calibration: the main car 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 car clock receives the potentiometer input upper limit record message, the potentiometer value when the car clock handle is pushed to the maximum gear position (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 car clock receives the potentiometer input lower limit record message, the potentiometer value when the car clock handle is pushed to the minimum gear position (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 car clock receives the potentiometer input record reading message, the calibration of the potentiometer input parameters is completed according to the recorded maximum potentiometer value and the minimum potentiometer value and the gear specification currently used.

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

[0061] Exemplarily, in the embodiment of the present application, the multimeter can be adjusted to the current measurement gear, and the main car clock car command current output interface is connected to the multimeter according to the electrical wiring diagram, and then the car command current output survey message is sent to the main car clock using the CAN setting software or the remote control system, 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 car command current output survey messages containing different calibration data multiple times, and the measured values ​​of the multimeter are observed, and the calibration data corresponding to the car command current output survey message when the measured values ​​of the multimeter are the first current (such as 4 mA) and the second current (such as 20 mA) are recorded respectively. Subsequently, the car command current output survey end message is sent to the main car clock using the CAN setting software or the remote control system, and the main car clock exits the car command current output survey mode. Finally, the main 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 according to 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 main 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] Exemplarily, the embodiment of the present application adjusts the signal generator to the current output mode, and connects the main vehicle clock dimming current input interface 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 embodiment of the present application provides an online calibration function, which can complete the calibration of the potentiometer input, the vehicle command current output, the dimming current input, etc. during the normal operation of the ship. In this way, when the gear position recognition is inaccurate, the vehicle command signal is abnormal, and the light adjustment is abnormal, the data calibration can be completed in time to ensure that the gear position recognition, vehicle command signal and light adjustment are normal.

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

[0066] Preferably, the main car clock periodically sends a fault feedback message (USB fault feedback message) to the computer, wherein the content of the fault feedback message includes a comprehensive fault state, a CAN communication fault state, and a potentiometer disconnection fault state. Specifically, the core processing module makes a judgment based on the CAN heartbeat message, the vehicle command information CAN message, and the CAN feedback message sending state of the main car clock. If there is an abnormal message sending state, the fault feedback message sent includes the CAN communication fault state; the core processing module makes a judgment based on the potentiometer connection state. If the potentiometer is disconnected, the fault feedback message sent includes the potentiometer disconnection fault state; the core processing module makes a comprehensive judgment based on other fault states in the message, and sends a fault feedback message including the comprehensive fault state. In this way, the computer can timely record the CAN communication fault state, the potentiometer disconnection fault state, etc. of the main car clock system, and provide support for subsequent fault query and diagnosis.

[0067] The ship main clock system of the embodiment of the present application can be configured in two ways, one is a two-clock mode, and the other is a three-clock mode. The two-clock mode includes the main clock on the driving console (the sending position) and the main clock on the centralized control console (the return position), and the three-clock mode includes the main clock on the driving console (the sending position), the main clock on the centralized control console (the return position 1), and the backup main clock on the centralized control console (the return position 2).

[0068] The control part of the remote control system can be switched between the driving control room, the centralized control console and the standby centralized control console. The remote control system can send system control information messages to the main car clock for remote operation. The message content includes the current control part of the system and the buzzer control command. The main car clock can drive the buzzer according to the buzzer control command (including the remote control buzzer control command and the car clock buzzer control command). When the control part of the remote control system is switched between the driving control console, the centralized control console and the standby centralized control console, the car command communication of the main car clock of each operating part is carried out through the CAN network interface, and the core processing module of each main car clock determines the car command indication (sound and light indication) and buzzer status (sound or not) of the indicator light of the replaced light board mask according to the driving control console, the centralized control console and the standby centralized control console as the current control operation part and the effective return command part according to the judgment and processing rules of whether the potentiometer is disconnected and whether the handshake communication is normal. When the main clock potentiometer is normal and the car order changes when the car clock handle is pushed, a car order information CAN message is sent for use by the main clocks of other operating parts. Each main clock receives the car order information CAN message sent by the main clocks of other operating parts that are paired with it according to the system part node setting, and each core processing module judges the communication status according to the message reception situation. The present invention provides an efficient data transmission and processing method, so that the control signal can be quickly transmitted between various operating parts, ensuring the timeliness and accuracy of the response. The core processing module of each main clock can make a decision quickly according to the current operating part and the effective return command part to ensure the correct transmission of the instruction. When switching the control part, the core processing module will confirm the validity of the new control source according to a series of judgment rules, avoiding illegal or unsafe control sources from taking over the system. This mechanism adds an extra layer of security, especially in key applications such as ship equipment. It is particularly important. And the logic processing of the main clocks of different operating parts when switching the control part is taken into account, so that universality and interchangeability can be achieved during fault debugging or equipment replacement, and the number of spare parts can also be reduced.

[0069] Among them, the core processing module of each main car clock determines several car command indications and buzzer states of the indicator light of the replaced light board mask according to several situations in which the driving console, the centralized control console and the spare centralized control console are respectively used as the current controlled operation position and the effective return command position, combined with the judgment and processing rules of whether its own potentiometer is disconnected and whether the handshake communication is normal, and lists the judgment and processing rules under several situations and states as shown in the following Tables 1-4.
