Buy Meizhou BeiDou GPS Positioning System pne888kj First, the vehicle positioning system overview Vehicle positioning system using GSM communication technology generally consists of three parts: 1 vehicle unit; 2 monitoring center; 3GSM communication service system (1) vehicle unit vehicle terminal equipment includes: control Unit (CPU), display unit (optional), GPS receiver, GSM mobile phone (or other communication module: such as Siemens TC35 or MC35, but redesigned peripheral circuits based on cell phone module interface), burglar alarm (optional). The main functions are: (1) Anti-theft alarm function: When an emergency occurs, the user can trigger a hidden alarm button. The vehicle-mounted unit will automatically transmit the position data in the GPS receiver to the monitoring center through the short message function of the GSM mobile phone. Anti-theft activation function, when the vehicle encounters illegal intrusion, automatically sends alarm information to the control center; (2) Navigation function: GPS provides accurate data such as position, speed, and direction of the moving target. No differential positioning accuracy is about 10m, and the differential accuracy is 3-5m. The system can navigate through the dispatch center or store electronic maps on the terminal. (3) Calling function: Car GSM mobile phone can make a call. When the user leaves the car, the mobile phone can also be used normally. (4) Service: Provides a set of service buttons. When the car owner needs the service, he presses the corresponding button and the service center provides the service. (2) The GPS differential reference module in the monitoring center of the monitoring center is used to generate differential correction information and sent to the middle yang processor; the yang processor will manage the database and various scheduling, command information and differential correction information will be passed through the GSM communication module. Send to each vehicle unit, and send the information sent by each vehicle unit to the electronic map or database for storage; the electronic map of GIS module of GIS will accurately display the real-time position of all monitored vehicles; GSM communication module The function is to send the command and differential correction signal sent by the middle yang processor to each onboard unit and receive the GPS information and sensor information of the vehicle sent by each onboard unit. (3) GSM Communication Service System The GSM communication service system consists of a GSM communication module and a GSM communication network. Its function is mainly to transmit data between the on-board unit and the monitoring center to ensure vehicle GPS information and sensor information sent by each onboard unit. The instructions sent by the yang processor and the differential correction signals are transmitted stably between the on-board unit and the monitoring center. Communication software uses VC++ to achieve: COMM_SEVER and COMM_CLIENT communication using WINSOCK components. China has formed a basically complete Internet of things industry system, and certain areas have formed a certain market size. The technology and industry support capabilities of network communications are relatively small compared to foreign countries. Sensors, RFID, and other perceptual end manufacturing industries, high-end software and integration services, and foreign countries The gap is relatively large. Although the industries such as instrumentation, embedded systems, software, and integration services have already reached a relatively large scale, the equipment and services related to the Internet of Things are still in the beginning. If the Internet is connected to people, then the car network is to join the car, people can communicate with the car, the car can take the initiative to display information on its own. Domestically, car networking is a form of expression in the Internet of Things. It has been demonstrated by a domestic expert group and is estimated to invest 2,000 million yuan. It is considered by the domestic academic community to be the first practical Internet of Things system. The important application of the transportation industry is also one of the industries with better IoT applications. In foreign countries, the Internet of Vehicles may be the Internet of Vehicles, or the Vehicular Network. The development of European car networking is obviously faster than in North America. For example, several European (Netherlands, Sweden, Switzerland, Germany) government officials and car companies participate in projects such as Telematics, and universities have higher rates of online literature. The United States can find the Ministry of Communications' Connected Vehicle project. Car networking has a broad industry segmentation demand, but the development of various market segments is not balanced. As a whole, the development of China's car networking industry is still in its infancy, and technologies, standards, products, and markets are not mature. In terms of market segments, school buses, coaches, tankers, buses, logistics vehicles, medical vehicles, official vehicles, and even private cars will become the focus areas of the car networking market segment, but due to different market segments in the car network There are great differences in policy trends, technologies, market maturity, and market demand. The development of the segmented market for car-based internet of things is very different. Research shows that: "Policy first, technology-led, demand-driven" will become the main mode for the development of China's car networking industry. In the Internet of Things, for example when you go to the supermarket to buy food, the "label" of vegetables will show its health and freshness. This "tag" can be a chip or a sensor instead of the plain paper label we see now. Similarly, in the Internet of Vehicles, the vehicle mounted terminal mounted on the vehicle can obtain vehicle information in real time, and various parameters and health conditions of the vehicle can be known by the owner in some form in real time. How to obtain, transmit, utilize, and control such information, Shanghai Chenhan Electronics and many R&D and design companies that have worked in the car networking field for many years proposed the concept of a car networking gateway. The introduction of the car networking gateway has realized the separation of data services and car networking application development. In the following, CARMAN, a high-intelligent multi-functional vehicle-mounted terminal and vehicle networking gateway-integrated product developed and designed by Shanghai Chenhan Electronics for many years, is used to understand some of the design ideas, workflows, and functions of the entire vehicle networking gateway. CARMAN's design idea is based on the existing wireless communication methods (TD-SCDMA/TD-LTE, WCDMA, CDMA2000 (EVDO)) as a platform to integrate the Internet and mobile communication networks for terminal and enterprise applications, and even for government applications. Unified interface. What is "five-point anti-theft" and what problems can be solved? The concept of “quintuple anti-theft” explains the first: vibration sensing, when the thieves touch the vehicle, sound and light alarm, deter thieves, alert the owner, and text message to notify the owner of the mobile phone second weight: battery stolen alarm, when the vehicle battery is Excluded and sent a text message “External vehicle power was removed” to the owner’s mobile phone. The third weight: shift the alarm, when the vehicle is removed from the set area by the thief, automatically send a "possible stolen" message to the owner's mobile phone. The fourth: electronic fence alarm: the owner can draw an arbitrary shape of the electronic fence on the map. When the vehicle leaves the fence, it immediately alerts. Fifth, the vehicle position is tracked. After the vehicle is stolen, the owner queries the real-time location of the vehicle through the mobile phone and the Internet. The vehicle returns the location information and implements the pursuing. The concept of "quintuple anti-theft" is an exclusive product developed by An Jiexing. It applies to the concept of patented products for anti-theft and pursuing of motorcycles and electric vehicles. It can handle the theft of a vehicle, detect the occurrence of theft and notify it in a timely manner. The owner's mobile phone can be positioned and tracked after the vehicle is stolen, providing the best technical support for the theft. The Meizhou Beidou GPS positioning system was purchased. In fact, most of the common fault code information is of little significance to the owner, or is exemplified by the popular fault code. "P0001 stands for Fuel Regulator Control Circuit / Open Circuit, P025A stands for Fuel Pump. The module control circuit / open circuit, P0103 represents the air flow sensor A circuit is high ... "is not a bit dizzy? In general, it is to detect some common faults in the powertrain system, chassis system, communication system, and body system. This information does not have any influence on the safety of the vehicle. Instant failures are displayed on the instrument panel. Airbags, seat belts, and excessive water temperatures will all directly alert you. When these cold data can not drive the enthusiasm of the owners, in the same way as the chicken ribs, how can they talk about attracting Bao insurers? The bottleneck of cracking and renewing the private protocol may be to realize that the value of obtaining information from the public fault code is limited, so everyone has tried hard to seek a breakthrough in cracking the private agreement of the original Can-bus, and the instantaneous fuel consumption analysis and hydraulic pressure , door power, light detection, vehicle remote monitoring and anti-theft ... ... features a full range of features, a mountain is also higher than a mountain. Auto OBD manufacturers can decode multiple data and systems by purchasing professional car decoders, but they are faced with the inevitable bottlenecks of proprietary protocols: 1. Not all private cars can be cracked, for example, the Volkswagen car set is high. The shielded gateway, the original car bus data is basically blocked after the gateway, even if there is decoding it is difficult to read the seatbelt, door windows and other data; 2, the private agreement is constantly updated, break the PIN code of a specific car directly The OBD private agreement related to whether the developer can read a certain model. The PIN code set by the automobile manufacturer changes every year, so that the original decoding cannot read the updated content in time, resulting in inaccurate data. Some of the eye-catching people also saw the OBD part of the tricks involved in the relevant functions of the private agreement, some people have no mercy to point out that the Lobo box “transient fuel consumption analysis” data cheating - “You think we do not know that most cars have no fuel Does the sensor matter? The fuel consumption error calculated based on the parameters such as the vehicle speed and the intake air amount may not be generally large. Two common sources of error are: 1) The fuel consumption statistics for air conditioning or the use of onboard entertainment systems; 2) OBD The reader can only send one command at a time to get one parameter. How can the fuel consumption calculated by using parameters of different time be called instantaneous fuel consumption? The installation position is inconsistent, and the data calibration has errors. The OBD interface adopts the trapezoidal 16DLC type connector, the trapezoidal interface. It is anti-misinsertion design to prevent short circuit caused by wrong insertion or other conditions affecting the use of vehicles, some manufacturers also use colored connectors for easy identification.The interface position of OBD is generally in the interior panel under the steering wheel, close to the driver Place the equipment near the knee to use it, but this is just a good condition. Some models, the installation will not be easy.
