Description

Technical Field

[0001] The present invention relates to the technical field of engine monitoring, and more specifically, to an intelligent engine monitoring system. Background Art

[0002] The principle of engine status monitoring is to monitor and feedback key parameters through various sensors. These parameters include engine temperature, exhaust temperature, speed, load, oil pressure, oil volume and oxygen content. By detecting and analyzing these parameters, the system can detect abnormal engine status in time and conduct early warning processing.

[0003] The existing engine electronic control monitoring system measures parameters through a series of sensors and then sends them to the electronic control unit (ECU). The ECU monitors and adjusts the key parameters of the engine in real time to ensure that the engine runs in the best condition. After the engine leaves the factory, the parameters that need to be monitored are fixed, and due to the limited number of pins on the ECU, it is difficult to expand the parameters monitored by the ECU.

[0004] With the development of engine technology and the changing operating conditions, more and more parameters need to be monitored. When the traditional engine monitoring system expands the monitoring parameters, it needs to rewire and add ECU expansion modules, which is a lot of work and has poor stability. Summary of the invention

[0005] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art. The purpose of the present invention is to provide an engine intelligent monitoring system that can conveniently expand the parameters monitored by the ECU.

[0006] The technical solution of the present invention is: an engine intelligent monitoring system, including an engine electronic control monitoring system, and also including an external sensor monitoring system, a diagnostic management platform, and a mobile terminal. The external sensor monitoring system includes an independent power supply module, a wireless receiver, and a wireless intelligent sensor. The wireless receiver is installed next to the ECU of the engine and connected to the ECU through a bus. The independent power supply module supplies power to the wireless receiver and the wireless intelligent sensor. The detection data of the wireless intelligent sensor is transmitted to the ECU through the wireless receiver. The ECU uploads the monitored parameters to the diagnostic management platform, and the diagnostic management platform sends the monitored parameter information to the mobile terminal through wireless communication.

[0007] As a further improvement, the independent power supply module includes a small generator and a battery. The small generator is driven by an engine belt shaft or an engine output shaft. The small generator charges the battery, and the battery supplies power to the wireless receiver and the wireless intelligent sensor.

[0008] Furthermore, the independent power supply module is an independent battery independent of the vehicle-mounted battery and is charged by the vehicle-mounted generator.

[0009] Furthermore, the wireless intelligent sensor includes a coolant temperature sensor, a coolant pressure sensor, an engine oil quality sensor, and a fuel quality sensor, and the coolant temperature sensor, the coolant pressure sensor, the engine oil quality sensor, and the fuel quality sensor are respectively installed at designated detection positions.

[0010] Furthermore, the wireless receiver is connected to the OBD port of the ECU via a SAEJ1939 bus.

[0011] Furthermore, the mobile terminal is a mobile phone, and a mobile phone APP for communicating with the diagnosis management platform is installed in the mobile phone.

[0012] Furthermore, the diagnostic management platform monitors various parameters of the engine in real time, and sends an alarm message to the mobile terminal when a parameter exceeds a standard; and sends a maintenance reminder message to the mobile terminal when the engine needs maintenance.

[0013] Beneficial Effects

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The present invention can conveniently expand monitoring parameters by setting up an external sensor monitoring system without the need for rewiring. The installation location of the wireless sensor is not restricted, the flexibility is high, the expansion workload is small, the line is simple and the stability is good, and it is very easy to expand in a machine that is already in use or a machine that has left the factory. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a schematic diagram of the present invention. DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0018] See also Figure 1, an engine intelligent monitoring system, including an electronic control monitoring system of the engine, and also including an external sensor monitoring system, a diagnostic management platform, and a mobile terminal. The external sensor monitoring system includes an independent power module, a wireless receiver, and a wireless intelligent sensor. The wireless receiver is installed next to the engine's ECU and connected to the ECU through a bus, which can reduce the bus length and improve transmission stability. The independent power module supplies power to the wireless receiver and the wireless intelligent sensor. Of course, the wireless intelligent sensor can also have its own battery, which makes the installation more flexible and convenient. The detection data of the wireless intelligent sensor is transmitted to the ECU through the wireless receiver, and the ECU uploads the monitored parameters to the diagnostic management platform. The diagnostic management platform sends the monitored parameter information to the mobile terminal through wireless communication.

[0019] In one embodiment, the independent power supply module includes a small generator and a battery. The small generator is driven by an engine belt shaft or an engine output shaft. The small generator charges the battery, and the battery supplies power to the wireless receiver and the wireless intelligent sensor.

[0020] In one embodiment, the independent power module is an independent battery independent of the vehicle battery and is charged by the vehicle generator.

[0021] The independent power supply module can reduce the impact on the original vehicle battery, thereby reducing the impact on the stability of the original electronic control monitoring system.

[0022] The wireless intelligent sensor includes a coolant temperature sensor, a coolant pressure sensor, an oil quality sensor, and a fuel quality sensor, which are installed at designated detection locations. Of course, the wireless intelligent sensor can also include other sensors that need to expand the corresponding monitoring parameters.

[0023] The wireless receiver is connected to the OBD port of the ECU via the SAEJ1939 bus, and has good stability.

[0024] The mobile terminal is a mobile phone, which is installed with a mobile phone APP for communicating and connecting to the diagnosis management platform, so that the engine status can be checked anytime and anywhere.

[0025] The diagnostic management platform monitors various parameters of the engine in real time. When any parameter exceeds the standard, an alarm message is sent to the mobile terminal; when the engine needs maintenance, a maintenance reminder message is sent to the mobile terminal.

[0026] The present invention can conveniently expand monitoring parameters by setting up an external sensor monitoring system, and can be easily expanded in a machine that has been used or a machine that has left the factory.

[0027] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
