[0021] Reference Figure 1 - Figure 3The intelligent engine based on the high-precision Beidou positioning system of the present invention includes an engine body for providing power for a motorcycle and a monitoring device for monitoring the state of the engine body and diagnosing faults. The monitoring device includes an ECU module 21 arranged in the engine body for obtaining state information of the engine body, a Beidou GPS dual-mode positioning module 22 for positioning the engine body, and a main control module 23 for overall management. The ECU module 21 and the Beidou GPS dual-mode positioning module 22 respectively exchange data with the main control module 23. Specifically, the ECU module 21 can obtain the status information of the engine body in real time, and the main control module 23 exchanges data with the ECU module 21, so the main control module 23 can obtain the status information about the engine body sent by the ECU module 21. Therefore, the manufacturer, user or maintenance personnel can quickly and accurately realize real-time monitoring of the engine status by obtaining the status information of the engine body in the main control module 23; because the status information of the engine body includes different status values ​​such as injector voltage, injection pulse width, ignition angle, intake pressure, engine speed, cylinder temperature, intake temperature, oxygen sensor value, throttle opening, etc., and these status values ​​have their own range values ​​for normal operation, so by detecting and judging the status information of the engine body, if the status value exceeds the range value applicable to the work, it can be judged that the engine body is abnormal. At this time, the main control module 23 can issue an alarm to remind the manufacturer, user or maintenance personnel that the current engine body is in an abnormal state. Therefore, by receiving the status information about the engine body sent by the ECU module 21 through the main control module 23, functions such as fast and accurate engine status monitoring, fault diagnosis, and fault alarm can be realized, so that manufacturers, users, and maintenance personnel can understand the status of the engine in a timely manner, reducing the difficulty of engine fault diagnosis and maintenance. In addition, the Beidou GPS dual-mode positioning module 22 can accurately obtain the location of the engine body, thereby realizing accurate positioning of the motorcycle.

[0022] Among them, refer to Figure 1 - Figure 3The monitoring device also includes a start-stop control mechanism for controlling the engine body to start and stop according to the state information of the engine body. The start-stop control mechanism includes a start control module 31 for starting the engine body and a flameout control module 32 for shutting down the engine body. The start control module 31 and the flameout control module 32 are respectively connected to the main control module 23. Specifically, when the main control module 23 receives a brake signal sent by the ECU module 21 and the vehicle speed is zero, the main control module 23 will start the flameout control module 32, thereby stopping the operation of the engine body and saving energy. When the brake signal received by the main control module 23 is invalid, the main control module 23 will automatically start the start control module 31, thereby starting the operation of the engine body. In addition, when the engine body stops running, the main control module 23 will automatically enter a dormant state, and will send an offline signal to the ECU module 21 to put the ECU module 21 in an offline state.

[0023] Among them, refer to Figure 1 - Figure 3 The monitoring device also includes an acceleration sensor 4 for detecting continuous vibration of the engine body, and the acceleration sensor 4 is connected to the main control module 23. Specifically, when the intelligent engine of the present invention is in a dormant state, if the acceleration sensor 4 detects continuous vibration, the acceleration sensor 4 will send a trigger signal to the main control module 23, thereby waking up the main control module 23, so that the main control module 23 locates the current position according to the Beidou GPS dual-mode positioning module 22, so that the user can understand the position of the vehicle in real time.

[0024] Among them, refer to Figure 1 - Figure 3 The monitoring device further includes a communication interface module 5 for providing a data transmission channel between the ECU module 21 and the main control module 23, and the communication interface module 5 includes a UART bus and / or a CAN bus. In addition, the intelligent engine of the present invention further includes a storage module 6 for storing the state information of the engine body detected by the ECU module 21, and the storage module 6 is connected to the main control module 23. Specifically, the interior of the engine body is provided with various sensors for respectively detecting status values ​​such as injector voltage, injection pulse width, ignition angle, intake pressure, engine speed, cylinder temperature, intake temperature, oxygen sensor value, throttle opening, etc., and these sensors are all connected to the ECU module 21. Therefore, when the engine body is working, the main control module 23 will obtain various status values ​​of the engine body from the ECU module 21 through the communication interface module 5 in real time, such as injector voltage, injection pulse width, ignition angle, intake pressure, engine speed, cylinder temperature, intake temperature, oxygen sensor value, throttle opening, etc., and the main control module 23 will save these status values ​​in the storage module 6 so that the user can view them at any time, thereby realizing functions such as fast and accurate engine status monitoring and fault diagnosis.

[0025] Among them, refer to Figure 1 - Figure 3 The intelligent engine of the present invention also includes a rechargeable power module 7 for providing a working power supply and a solar energy conversion module 8 for solar charging the rechargeable power module 7. The detection pin of the rechargeable power module 7 is connected to the main control module 23, and the solar energy conversion module 8 is connected to the rechargeable power module 7. Specifically, the main control module 23 can detect the power level of the rechargeable power module 7 in real time through the detection pin of the rechargeable power module 7, and can perform corresponding operation processing according to the real-time power level of the rechargeable power module 7. For example, when the power level of the rechargeable power module 7 is less than 12V, the main control module 23 will turn on the Beidou GPS dual-mode positioning module 22 for real-time positioning, and at the same time, a low voltage alarm will be issued. In addition, when the surrounding environment is sunny, the solar energy conversion module 8 will automatically work, thereby using solar energy to power the intelligent engine of the present invention, and at the same time charging and storing energy for the rechargeable power module 7.

[0026] Among them, refer to Figure 1 - Figure 3The startup control module 31 includes a first N-channel field effect transistor Q19, a second N-channel field effect transistor Q18, a first P-channel field effect transistor Q17, a first diode D16 and a second diode D17; the gate of the first N-channel field effect transistor Q19 and the gate of the second N-channel field effect transistor Q18 are respectively connected to the positive startup pin STR+EN and the negative startup pin STR-EN of the main control module 23; the drain of the first N-channel field effect transistor Q19 is connected to the gate of the first P-channel field effect transistor Q17 through the first voltage-dividing resistor R71, and the source and The source of the second N-channel field effect transistor Q18 is connected to the reference ground; the source and drain of the first P-channel field effect transistor Q17 are respectively connected to the working power supply and the positive electrode of the first diode D16, and the source and gate of the first P-channel field effect transistor Q17 are connected through the second voltage-dividing resistor R70; the cathode of the first diode D16 and the cathode of the second diode D17 are connected and connected to the positive drive end STR+OUT of the engine body, and the drain of the second N-channel field effect transistor Q18 is respectively connected to the anode of the second diode D17 and the negative drive end STR-OUT of the engine body. Specifically, when the main control module 23 turns on the start control module 31, the positive start pin STR+EN and the negative start pin STR-EN of the main control module 23 respectively turn on the first N-channel field effect transistor Q19 and the second N-channel field effect transistor Q18. At this time, there is a voltage difference between the gate and the source of the first P-channel field effect transistor Q17, so the first P-channel field effect transistor Q17 will be turned on. Therefore, the working power supply can form a power supply circuit through the positive drive terminal STR+OUT and the negative drive terminal STR-OUT of the engine body, thereby driving the engine body to operate.

[0027] Among them, refer to Figure 1 - Figure 3 , the flameout control module 32 includes a first transistor Q23 and a relay K1, the base and emitter of the first transistor Q23 are respectively connected to the flameout control pin FAO_EN of the main control module 23 and the reference ground, the input end and the output end of the relay K1 are respectively connected to the working power supply and the collector of the first transistor Q23, and the fixed contact and the moving contact of the relay K1 are respectively connected to the flameout terminal FLAMEIN of the engine body and the reference ground. Specifically, when the main control module 23 starts the flameout control module 32, the flameout control pin FAO_EN of the main control module 23 will turn on the first transistor Q23. At this time, the working power flows through the input end and the output end of the relay K1 and flows back to the reference ground through the first transistor Q23, so the moving contact of the relay K1 will be closed, so that the flameout terminal FLAMEIN of the engine body is connected to the reference ground, thereby shutting down the operation of the engine body.

[0028] Among them, refer to Figure 1 - Figure 3The intelligent engine of the present invention also includes a service cloud platform 10 for processing the status information of the engine body, and the monitoring device also includes an Internet of Things communication module 9 for data interaction with the service cloud platform 10, and the Internet of Things communication module 9 is connected to the main control module 23. Specifically, the Internet of Things communication module 9 includes one or more of a GSM module, a LoRA module, and a NB-LoT module. Therefore, according to different application environments, the respective characteristics of the GSM module, the LoRA module, and the NB-LoT module can be combined for corresponding selection and use. In addition, when the engine body is working, the main control module 23 will turn on the Internet of Things communication module 9 and the Beidou GPS dual-mode positioning module 22, obtain the location-related information of the engine body through the Beidou GPS dual-mode positioning module 22, and upload it to the service cloud platform 10 through the Internet of Things communication module 9 together with various status information of the engine body temporarily stored in the storage module 6. The main control module 23 monitors the various status values ​​of the engine body in real time, and uploads the abnormal information to the service cloud platform 10 when an abnormality is found. If the abnormality will cause further failure of the engine body, the main control module 23 will stop the operation of the engine body through the flameout control module 32 to prevent the failure from further deteriorating, thereby protecting the engine body.

[0029] Specifically, the Beidou GPS dual-mode positioning module 22 has two working modes: autonomous positioning and positioning in cooperation with the service cloud platform 10. When the Beidou GPS dual-mode positioning module 22 performs autonomous positioning, the Beidou GPS dual-mode positioning module 22 automatically receives navigation messages from Beidou and GPS satellites and performs position calculations on them. When the main control module 23 needs it, the Beidou GPS dual-mode positioning module 22 provides the latitude and longitude coordinates of the current intelligent engine to it. When the Beidou GPS dual-mode positioning module 22 cooperates with the service cloud platform 10 for positioning, the Beidou GPS dual-mode positioning module 22 first obtains the original data of pseudorange and carrier phase through Beidou and GPS satellites, and then sends the original data to the main control module 23, and the main control module 23 uploads the original data to the service cloud platform 10 through the Internet of Things communication module 9. The service cloud platform 10 processes the original data and finally outputs the high-precision position information of the intelligent engine.

[0030] In addition, refer to Figure 1 and Figure 4The intelligent engine of the present invention also includes an on-board electrical appliance control module for starting the on-board electrical appliances, and the on-board electrical appliance control module is connected to the main control module 23. Specifically, the on-board electrical appliance control module includes a second P-channel field effect transistor Q16, a third P-channel field effect transistor Q15, and a second triode Q24. The base and emitter of the second triode Q24 are respectively connected to the on-board electrical appliance control pin ACC_EN of the main control module 23 and the reference ground. The collector of the second triode Q24 is respectively connected to the gate of the second P-channel field effect transistor Q16 and the gate of the third P-channel field effect transistor Q15 through a third voltage-dividing resistor R58. The second P-channel field effect transistor Q16 is connected to the gate of the second P-channel field effect transistor Q16 and the gate of the third P-channel field effect transistor Q15. The source of the transistor Q16 and the source of the third P-channel field effect transistor Q15 are connected to the gate of the second P-channel field effect transistor Q16 and the gate of the third P-channel field effect transistor Q15 through the fourth voltage-dividing resistor R49, respectively. In addition, the source of the second P-channel field effect transistor Q16 and the source of the third P-channel field effect transistor Q15 are both connected to the working power supply, and the drain of the second P-channel field effect transistor Q16 and the drain of the third P-channel field effect transistor Q15 are both connected to the vehicle electrical power supply ACC. When the vehicle electrical control module is working, the vehicle electrical control pin ACC_EN of the main control module 23 turns on the second triode Q24. At this time, there is a voltage difference between the source and the gate of the second P-channel field effect transistor Q16 and the third P-channel field effect transistor Q15, so the second P-channel field effect transistor Q16 and the third P-channel field effect transistor Q15 are both turned on, so the vehicle electrical power supply ACC can make various electrical appliances on the vehicle work normally.

[0031] In summary, the main control module 23 communicates with the ECU module 21 through the communication interface module 5, reads the state information of the engine body, and then uploads the state information to the service cloud platform 10 in real time through the Internet of Things communication module 9. The service cloud platform 10 combines the big data analysis and processing technology with the collected state information of the engine body to realize functions such as driving behavior analysis and engine tuning parameter optimization. The service cloud platform 10 will count and rank the real-time fuel consumption information of all vehicles, analyze the engine data, vehicle speed, brake and other state data of vehicles with fuel consumption exceeding the average value, and remind the driver to improve the driving behavior for the problem of high fuel consumption caused by the driver, such as frequent sudden acceleration, sudden braking, long-term idling and parking; at the same time, various characteristic curves of the engine body are generated according to the state data of the engine body, such as speed characteristic curve, external characteristic curve, load characteristic curve, etc., and then analyze the rationality of the parameters such as ignition angle, injection pulse width, throttle opening of the engine body under various working conditions according to the characteristic curve, and analyze the optimization scheme in combination with the use environment in different regions.

[0032] Therefore, the intelligent engine of the present invention has the following advantages:

[0033] Intelligence: It can perform fault diagnosis based on the real-time monitoring of the engine status, help maintenance personnel quickly locate the fault, and promptly and proactively notify relevant personnel when deviations in engine status parameters are found, and take appropriate measures to ensure that the fault does not deteriorate further;

[0034] Environmental protection: Through the realization of the start-stop function of the start-stop control mechanism, the fuel consumption of idling in situ can be reduced, thereby further saving energy, reducing emissions and protecting the environment;

[0035] Big data analysis: Through all-round real-time data collection and storage of the engine body, big data analysis can provide strong data support for manufacturers to optimize their products.
