[0031] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0032] Figure 1 The first circuit composition schematic diagram of the outboard engine instrument provided by the embodiments of the present application is shown in Figure 1 The outboard engine instrument includes a controller 10, an hour meter 27, a K bus transceiver circuit 15, a state indicator lamp driving circuit 23 and a maintenance indicator lamp 24. The hour meter 27 is electrically connected with the controller 10, and the hour meter 27 is used to start recording the working hours of the outboard engine under a preset condition. The controller 10 is electrically connected with the K bus transceiver circuit 15. The controller 10 is configured to output a control signal for limiting the torque and the speed of the outboard engine to the outboard engine through the K bus transceiver circuit 15 when the working hours of the current maintenance period exceed the preset maintenance period. The state indicator lamp driving circuit 23 is electrically connected with the maintenance indicator lamp 24 and the controller 10, and the state indicator lamp driving circuit 23 drives the maintenance indicator lamp 24 to send a reminder signal according to the working hours of the current maintenance period and the preset maintenance period.

[0033] Exemplarily, the first maintenance time of the outboard engine instrument is t1 hours, the cumulative working time of the outboard engine instrument reaches (t1-1) hours, and the state indicator lamp driving circuit 23 drives the maintenance indicator lamp 24 to send a reminder signal. The reminder signal sent by the maintenance indicator lamp 24, that is, the maintenance symbol flashes, reminding the user that the outboard engine instrument needs to be maintained.

[0034] The outboard engine instrument provided by the embodiment of the utility model, according to the working hours of the current maintenance period and the preset maintenance period, reminds the user to maintain the outboard engine through the maintenance indicating lamp 24 before the working hours of the current maintenance period reach the preset maintenance period.When the working hours of the current maintenance period exceed the preset maintenance period, the control signal of the limiting torque and rotating speed is outputted to the outboard engine through the K bus transceiver circuit 15, so as to limit the torque and rotating speed of the outboard engine, prevent the outboard engine from malfunctioning or cumulative damage due to large torque and high rotating speed operation without timely maintenance, protect the outboard engine, and further remind the user to maintain the outboard engine as soon as possible, prolong the service life of the outboard engine.

[0035] Meanwhile, the existing outboard engine instrument mainly adopts the K bus protocol, and when upgrading the firmware, a special computer needs to be equipped, and the operation is complex and difficult to carry.

[0036] Figure 2 The second outboard engine instrument circuit composition schematic diagram provided by the embodiment of the utility model is provided with reference to Figure 2 The K bus transceiver circuit 15 further comprises a reserved interface. The reserved interface is used for connecting the preset OBD module 25, acquiring external firmware upgrade data, and providing the outboard engine instrument for firmware upgrade.

[0037] Exemplarily, the OBD module 25 comprises a Bluetooth module, the OBD module 25 communicates with the external equipment (for example, a mobile phone) through the Bluetooth module, and receives the external firmware upgrade signal transmitted by the external equipment. The K bus transceiver circuit 15 is connected with the controller 10, and when the outboard engine instrument needs to be upgraded, only an OBD module 25 needs to be connected outside the K bus transceiver circuit 15. A special APP of the mobile phone is opened, for example, the Bluetooth module of the mobile phone communicates with the Bluetooth module in the OBD module 25, and the firmware of the outboard engine instrument is upgraded, which is convenient to operate, simple in steps, and ensures the long-term normal work of the outboard engine instrument.

[0038] Exemplarily, with reference to Figure 2 The outboard engine instrument further comprises a memory 14, the memory 14 is electrically connected with the controller 10, and the memory 14 stores a driver program. The firmware upgrade of the outboard engine instrument means that the driver program stored in the memory 14 is upgraded.

[0039] In addition, the existing outboard engine instrument has a key limitation in the aspect of outboard engine maintenance, that is, the working time of the outboard engine cannot be accurately recorded.

[0040] Optionally, the memory 14 is configured to store the working hours written by the controller 10 at a preset time interval.

[0041] Optionally, the preset time interval is less than or equal to 6 seconds. In the related art, the data of the working hours is written into the memory 14 once every 6 minutes. In the embodiment of the utility model, the hour meter 27 starts timing, and the controller 10 writes the data of the working hours into the memory 14 for storage every 6 seconds, shortens the storage interval, and writes the data of the working hours into the memory 14 once before the instrument power of the outboard engine instrument is turned off after the outboard engine is turned off. The timing error of the hour meter 27 is reduced.

[0042] Optionally, the controller 10 is configured to generate a check byte in a preset manner according to the working hours. The memory 14 is configured to store the working hours and the check byte at a preset address. The controller 10 is further configured to check the check byte when reading the working hours from the preset address.

[0043] Illustratively, the controller 10 writes the working hours into different addresses of the memory 14 respectively, and each address is subjected to CRC16 check. If the outboard engine instrument malfunctions and the data stored in the memory 14 is modified, the controller 10 can determine the modified backup data by relying on the check byte, overwrite it with the correct backup data, complete data recovery, reduce the timing error, and prevent data loss.

[0044] Optionally, with reference to Figure 2 The hour meter 27 is further used to end recording the working hours when the speed of the outboard engine is 0 and the oil pressure low switch signal is valid. After the outboard engine is turned off, the hour meter 27 stops timing and saves the working hours.

[0045] Illustratively, the preset condition under which the hour meter 27 starts recording the working hours of the outboard engine is that the speed of the outboard engine is greater than 500 r / min after the outboard engine is started, and the oil pressure low switch is turned off, at which time it is confirmed that the outboard engine is in a normal working state.

[0046] Illustratively, when the oil pressure of the outboard engine is insufficient, the oil pressure low switch is turned on, the controller 10 controls the speed signal conditioning circuit 22 to limit the torque and speed of the outboard engine connected to the outboard engine instrument, and protects the outboard engine.

[0047] Furthermore, the existing outboard engine instrument uses the ACC power supply of the ignition switch for power supply, and after the outboard engine instrument is powered off, the pointer cannot be reset to zero, and the hour meter cannot record data in time, which also leads to a large timing error and even data loss.

[0048] Optionally, with reference to Figure 2The instrument power supply of the outboard engine instrument includes a storage battery 26 of the ship. The outboard engine instrument further includes an ACC detection and low-power processing circuit 16, which is electrically connected with the controller 10 and the storage battery 26. The ACC detection and low-power processing circuit 16 is used for detecting an ACC signal of the ship and controlling the on or off of the instrument power supply according to the detection result of the ACC signal.

[0049] The outboard engine instrument of the present application is powered by connecting the storage battery 26 of the ship or yacht. By arranging the ACC detection and low-power processing circuit 16, the instrument power supply can be kept on for a preset maintenance time after the ignition switch is turned off, so that the power-off zero of the outboard engine instrument can be completed during the period, the working hours of the outboard engine instrument are saved, the timing error is reduced, and data loss is prevented. After the maintenance time ends, the instrument power supply is turned off, so that the uA level ultra-low power consumption of the instrument is realized.

[0050] For example, after the ignition switch is turned on, the ACC detection and low-power processing circuit 16 can detect the ACC signal and turn on the instrument power supply. After the ignition switch is turned off, the ACC detection and low-power processing circuit 16 detects that the ACC signal disappears, and the instrument power supply is kept on for a maintenance time, and the instrument power supply is turned off after the maintenance time ends.

[0051] Optionally, referring to Figure 2 The outboard engine instrument further includes a stepping motor 13 and a pointer, and the stepping motor 13 is electrically connected with the controller 10. The stepping motor 13 is used for controlling the position of the pointer, and controls the pointer to zero during the maintenance time after the ACC signal disappears and before the instrument power supply is turned off. The stepping motor 13 controls the position of the pointer of the outboard engine instrument, and improves the data display accuracy of the outboard engine instrument.

[0052] For example, after the ignition switch is turned off and the controller 10 detects that the ACC signal disappears through the ACC detection and low-power processing circuit 16, the stepping motor 13 receives the instruction of the controller 10 and performs zero processing on the instrument pointer.

[0053] Optionally, referring to Figure 2 The outboard engine instrument further includes a memory 14. The memory 14 is electrically connected with the controller 10, and the memory 14 is configured to write the working hours once during the maintenance time after the ACC signal disappears and before the instrument power supply is turned off. In the embodiment of the present application, the data of the working hours once is written to the memory 14 before the instrument power supply of the outboard engine instrument is turned off after the outboard engine is turned off, and the timing error of the hour meter 27 is reduced.

[0055] Exemplarily, the controller 10 controls the display screen 11 to display information, so as to facilitate the user to view.

[0056] As an example, the display screen 11 can be a 128*64 dot matrix LCD, and the memory 14 is an EEPROM memory 14, and the type of the display screen 11 and the memory 14 is not limited in the utility model.

[0057] Exemplarily, referring to Figure 3 The outboard engine instrument further comprises a balance sensor signal conditioning circuit 17, which is connected with the controller 10 and used for acquiring the balance sensor signal. The existing balance sensor is a horizontal sliding rheostat, which changes the resistance value according to the change of the angle to detect the balance condition; the precision is low, and the balance table pointer cannot be accurately indicated at the zero scale when installed. The balance sensor signal conditioning circuit 17 can be used to calibrate the balance sensor; when the balance sensor is calibrated, the sensor can be adjusted at the lowest, vertical and highest positions, the balance sensor signal conditioning circuit 17 detects the resistance value of the balance sensor at the three positions and confirms with the corresponding scale, completes the calibration of the two end values and 0 value of the balance sensor, and thus improves the detection precision of the balance sensor.

[0058] Exemplarily, referring to Figure 3 The outboard engine instrument further comprises a first filter and protection circuit 18, which is connected with the K bus transceiver circuit 15 and used for filtering the noise entering the K bus transceiver circuit 15. The first filter and protection circuit 18 processes the signal entering the K bus transceiver circuit 15, removes the noise, and ensures the normal work of the K bus transceiver circuit 15.

[0059] Exemplarily, referring to Figure 3 The outboard engine instrument further comprises a second filter and protection circuit 19, which is connected with the controller 10 and used for filtering the noise entering the controller 10. The second filter and protection circuit 19 processes the signal entering the controller 10, removes the noise, and ensures the normal work of the controller 10.
