BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a schematic diagram of a specific implementation mode 1 of the present invention. DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0021] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0022] An intelligent vehicle-mounted drunk driving monitoring system, such as Figure 1As shown, it includes a data processing module, a pressure sensing module, an alcohol detection module, an alarm module, a GPS (English full name: Global Positioning System, Chinese full name: Global Positioning System) positioning module and a GPRS (English full name: General Packet Radio Service, Chinese full name: General Packet Radio Service Technology) communication module. The data processing module is a single-chip microcomputer, which is the core control element of the system and is electrically connected to the pressure sensing module, the alcohol detection module, the GPS positioning module and the GPRS wireless communication module. In this embodiment, the STM32 single-chip microcomputer is selected, which is a series of microcontrollers developed by STMicroelectronics Group and is designed for embedded applications requiring high performance, low cost and low power consumption, which just meets the design requirements and design principles of the vehicle-mounted alcohol detection system.

[0023] Specifically, the pressure sensing module is arranged under the main driver's seat of the vehicle, and is used to detect the pressure on the main driver's seat of the vehicle, and automatically compare it with the pressure threshold to determine whether the vehicle is driven. In this embodiment, the pressure sensing module includes a thin resistive pressure sensor. When the sensing film area is subjected to pressure, its resistivity changes accordingly. The pressure and resistivity are inversely proportional. It has a sensitive response and is suitable for pressure detection of the vehicle's driving seat to determine whether the vehicle is driven. Through a dual voltage comparator, the pressure value sensed by the pressure sensor can be compared with the pressure sensing threshold of the vehicle's driving seat. When the pressure exceeds the threshold, it can be determined that a driver is driving the vehicle. When the pressure on the main driver's seat of the vehicle is greater than the pressure threshold, the alcohol detection module will automatically start.

[0024] Specifically, the alcohol detection module is installed around the driving position of the vehicle, and is used to detect the alcohol content in the driver's exhaled gas, and automatically compare it with the alcohol threshold. The exhaled gas alcohol content detection method generally measures the alcohol concentration based on the change in the resistivity of the gas-sensitive element of the sensor in the alcohol-containing gas. Sensors are mainly divided into electrochemical type, semiconductor type and infrared type. Under the action of a specific catalyst, the alcohol gas in the electrochemical alcohol sensor undergoes an electrochemical reaction inside the sensor, performs energy conversion to generate electrical energy, and the alcohol concentration is determined by measuring the voltage by measuring the circuit; the gas-sensitive element made of semiconductor material in the semiconductor alcohol sensor has different resistivity in different concentration gases, and the exhaled gas alcohol concentration is measured according to the change in resistivity; the infrared alcohol sensor adopts the principle of infrared spectroscopy. When infrared rays are directed to the exhaled alcohol gas, the exhaled alcohol concentration is reflected according to the different degrees of infrared absorption. In this embodiment, the alcohol detection module uses a sensor made of semiconductor material tin dioxide, whose conductivity changes with the change of alcohol concentration, has high alcohol sensitivity, good resistance to external gas interference, and is small in size and low in cost. In some other examples, the system may also include a display module for displaying the alcohol content detected by the alcohol detection module and the warning issued by the alarm module.

[0025] Specifically, the alarm module is used to issue an early warning and make the car engine self-lock. When the alcohol content detected by the alcohol detection module is greater than the alcohol threshold, the alarm module will automatically issue an early warning, a voice alarm prohibits driving after drinking, and triggers the engine to self-lock, which is to prevent driving after drinking and avoid accidents caused by driving after drinking; of course, when the detected alcohol content is less than the alcohol threshold, the system can also issue a voice prompt to drive safely. The early warning issued by the alarm module includes at least a sound signal and a light signal, which reminds the driver auditorily and visually to stop driving after drinking.

[0026] Specifically, the GPS positioning module is used to obtain the vehicle's location information, which includes at least longitude and latitude. As GPS technology matures, the cost of GPS equipment is getting lower and lower, and GPS equipment is becoming more and more common. GPS equipment captures signals from a certain number of satellites and tracks their satellite movements, transforms and processes received satellite signals, parses navigation messages sent by GPS satellites, and calculates corresponding geographic location information, time information and other information.

[0027] Specifically, the GPRS communication module is used to establish a network connection for the system, and upload specific data to the cloud server through the MQTT communication protocol, and the cloud server sends the received specific data to the traffic control platform and the owner driving supervision platform, and the specific data at least includes the license plate information, location information, and alcohol content data of the driver of the vehicle. In the present embodiment, the GPRS communication module adopts the SIM800C communication module, and the SIM800C module is powerful, and it can send and receive GSM text messages, and it has a built-in TCP / IP (English full name: Transmission Control Protocol / InternetProtocol, Chinese full name: Transmission Control Protocol / Internet Protocol) protocol stack, and can realize data transmission through TCP / IP networking, and can also realize LBS (English full name: Location Based Services, Chinese full name: Based on location service) information positioning through the base station, and obtain the location of the base station to realize user positioning, and it works stably, has a mini shape, is cheap and affordable, and is suitable for equipment such as vehicle-mounted positioning.

[0028] GPRS is a packet-switched data carrying and transmission method developed on the basis of GSM (Global System for Mobile Communications). GPRS is an extension of GSM, which realizes the smooth transition from 2G to 3G and provides infrastructure. It breaks the traditional way of thinking that GSM network can only provide circuit switching. It realizes packet switching only by adding corresponding functional entities and partially updating the existing base station system. GPRS is transmitted in the form of data packets, realizing "pay as you use", thus reducing the cost of use. GPRS has fast transmission speed; it is always online, with short access time and no need to dial again to establish a connection; it is only charged according to data flow, changing the charging according to the Internet time, realizing the principle of pay-as-you-go, which greatly saves the cost of use; it supports TCP / IP connection and increases the coverage. TCP / IP protocol is a communication protocol for the Internet. It is an IP-based protocol cluster used for information transmission between different networks. It has established standards and methods for communication at various structural levels in the network. It is the core protocol of the Internet and the core protocol of most networks.

[0029] MQTT (Message Queuing Telemetry Transport) is a "lightweight" instant messaging protocol based on the publish / subscribe paradigm developed by IBM (International Business Machines Corporation). It is lightweight, simple, open and easy to implement. The protocol is built on the TCP / IP protocol and provides an ordered, lossless, two-way connection. It is widely used in the Internet of Things. The purpose of implementing the MQTT protocol is to connect users to servers for data transmission and communication. During the communication process, the MQTT protocol is mainly composed of clients and servers. Usually, clients can be publishers and subscribers, and the two can convert to each other. The server is mainly composed of servers to receive and send data, and it acts as an agent.

[0030] In this embodiment, the cloud server is an Alibaba Cloud server, and the data information of the system hardware and software is transmitted through the Alibaba Cloud server. At present, the Alibaba Cloud Internet of Things platform is already the largest Internet of Things platform in China. In the Internet of Things architecture, it can be roughly divided into four levels: application layer, platform layer, network layer and perception layer. The perception layer is the embedded system equipment, including STM32 single-chip microcomputer, sensor and chip system, etc.; the network layer is communication technology such as 4G, 5G and WIFI; the platform layer is the Internet of Things platform, which belongs to the middle structure layer and plays the role of connecting embedded devices and users. The embedded hardware system collects data through sensors and transmits it to the Internet of Things platform. The Alibaba Cloud Internet of Things platform provides one-stop equipment access, equipment management, monitoring and operation, data flow, data storage and other services. The system uses the MQTT protocol to connect the hardware system equipment to the Internet of Things platform, and creates a vehicle alcohol monitoring system product on the Alibaba Cloud Internet of Things platform.

[0031] In some other examples, the system may also include cloud computing technology for comprehensive processing and analysis of relevant penalties for drunk driving, which can improve the work efficiency of relevant law enforcement personnel; it may also include an Android mobile phone management platform for remotely receiving the specific data, realizing real-time data transmission, achieving real-time warning of drunk driving, realizing system intelligence and real-time, developing an Android mobile phone management platform, remotely receiving vehicle status information uploaded by the system hardware, realizing real-time data transmission, achieving real-time warning of drunk driving, reducing the law enforcement pressure of traffic law enforcement departments, and changing the traditional drunk driving detection method from passive to active. The Android mobile phone management platform realizes remote information interaction and realizes vehicle driver status monitoring. Whether it is the local traffic law enforcement department or the owner's family members, they can obtain the vehicle's drunk driving phenomenon through the Android mobile phone management platform, and prevent the occurrence of drunk driving behavior from the root. When the intelligent vehicle alcohol monitoring system hardware detects that the vehicle driver has drunk driving behavior and the alcohol concentration exceeds the standard, the hardware system uploads the owner information, vehicle location information, vehicle driver status and other information, and the Android mobile phone management platform will display the owner information, license plate number, vehicle location, and driver's alcohol concentration to the user through a visual interface.

[0032] The working principle of the system: the hardware equipment is designed using embedded technology. When the main driver's door is opened, the pressure sensing module is started to detect the pressure on the main driver's seat of the vehicle and compare it with the pressure threshold. When the pressure is greater than the pressure threshold, the alcohol detection module is started to detect the alcohol content exhaled by the driver and compare it with the alcohol threshold. When the detected alcohol content is greater than the threshold, an early warning is issued, the engine is triggered to lock itself, and the GPS positioning module is triggered to obtain the vehicle's location information. The GPRS communication technology is then used to report the vehicle's location and owner information to the cloud server, which is then forwarded to users and the traffic management platform through the cloud server to achieve an early warning of drunk driving behavior.

In addition, many modifications may be made to adapt specific situations to the teachings of the present invention without departing from the central concept of the present invention described herein.
