Problems solved by technology

[0004] The car rental industry is a special mobile industry with a complex personnel structure. However, the car rental industry has shown a downturn in recent years. One of the reasons is that the car rental industry has not been able to keep up with the development of society.
In the car rental industry, there are generally lagging vehicles and equipment, vehicles are still relatively old models, vehicle equipment has low technological content, equipment is not enough, and industry management costs are high.

Embodiment 1

[0051] The vehicle model of this embodiment is the Santana of the 2005 model;

[0052] The normal parameter intervals set by the management personnel are as follows:

[0053] Engine air intake: 2.0--4.0g / s;

[0054] Intake manifold vacuum: 64--71kPa;

[0055] Throttle opening: 2--5 degrees;

[0056] Engine speed: less than 3000rpm;

[0057] Oxygen content in tail gas: less than 2%;

[0058] Engine water temperature: less than 100°C;

[0059] Fuel tank oil volume: more than 20%;

[0060] The MCU module uploads various parameters obtained by the ECU to the cloud service platform through the NB-IOT module. If the uploaded parameter value is always within the normal parameter range defined by the manager, the cloud service platform determines that the parameter is normal and the vehicle is in normal condition. ; If the uploaded parameter value is outside the normal parameter range defined by the management personnel, the cloud service platform determines that the parameter i...

Embodiment 2

[0071] The vehicle model of this embodiment is the Camry of the 2004 model;

[0072] The normal parameter intervals set by the management personnel are as follows:

[0073] Engine air intake: 3.0--4.0g / s;

[0074] Intake manifold vacuum: 74--80kPa;

[0075] Throttle opening: 2.3-6.0 degrees;

[0076] Engine speed: less than 4000rpm;

[0077] Oxygen content in tail gas: less than 3%;

[0078] Engine water temperature: less than 96°C;

[0079] Fuel tank oil volume: more than 20%;

[0080] The MCU module uploads various parameters obtained by the ECU to the cloud service platform through the NB-IOT module. If the uploaded parameter value is always within the normal parameter range defined by the manager, the cloud service platform determines that the parameter is normal and the vehicle is in normal condition. ; If the uploaded parameter value is outside the normal parameter range defined by the management personnel, the cloud service platform determines that the parameter i...

Embodiment 3

[0091] The vehicle model of this embodiment is the Civic of the 2007 model;

[0092] The normal parameter intervals set by the management personnel are as follows:

[0093] Engine air intake: 3.0--4.0g / s;

[0094] Intake manifold vacuum: 74--82kPa;

[0095] Throttle opening: 2.3-6.0 degrees;

[0096] Engine speed: less than 4000rpm;

[0097] Oxygen content in tail gas: less than 3%;

[0098] Engine water temperature: less than 96°C;

[0099] Fuel tank oil volume: more than 20%;

[0100]The MCU module uploads various parameters obtained by the ECU to the cloud service platform through the NB-IOT module. If the uploaded parameter value is always within the normal parameter range defined by the manager, the cloud service platform determines that the parameter is normal and the vehicle is in normal condition. ; If the uploaded parameter value is outside the normal parameter range defined by the management personnel, the cloud service platform determines that the parameter is...

Abstract

A car rental management system based on the Internet of Things, including a vehicle sensor module, the vehicle sensor module includes an air flow sensor for detecting the intake air volume of the engine, the air flow sensor is arranged in the intake pipe of the automobile engine, and the air flow sensor passes through the signal line Connected to the ECU, the ECU can obtain engine air intake parameters; the present invention utilizes a 32-bit high-performance MCU to communicate with the automobile ECU through the OBDII interface protocol and obtain sensor data such as engine speed, air-fuel ratio, idle speed and other parameters, and the MCU module obtains After receiving the sensor data, data processing and data forwarding are performed. The data will be sent to the cloud service platform through the NB-IOT wireless network module. The cloud service platform can perform big data analysis on the data sent by the NB-IOT module, and the driver can view and analyze the data on the server through the mobile terminal device. Managers can manage vehicles, acquire real-time locations, and predict faults.

Description

technical field [0001] The invention relates to the field of vehicle management, in particular to a car rental management system based on the Internet of Things. Background technique [0002] The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc., which enables all ordinary physical objects that can be independently addressed to realize interconnection and intercommunication. The Internet of Things has become a necessary trend in the development of the industry. The Internet of Things is generally a wireless network. On the Internet of Things, everyone can use devices to connect to the Internet to realize information interaction. The central computer can centrally manage machines, equipment, and personnel, and can also perform remote operations on home equipment and cars, as well as various applications such as location acquisition and prevention of item theft. [0003] The Internet of Vehicles refers to the inte...
