The EST527 car networking module is a car-level car network standard module OBDII protocol data analysis product, supporting the physical layer of ISO9141-2, ISO14230 (KWP), ISO15765 (CANBUS) and other protocols, through the OBD-16 standard interface Most of the existing ECUs perform diagnostic communication; the module converts the sensor values ​​of the automotive electronic control system into UART format data for output, and the user products are quickly connected with the car through the EST527_MINI module, and the secondary development of the vehicle networking product is easily realized. It also supports the standard OBDII car fault diagnosis function, supports DTC diagnostic request, fault code output, and fault code clear.
Module features: standard OBDII interface support; cover all major automotive protocols, dual MCU; processing speed is 5 times that of ELM327; the host computer does not need to perform any calculation, all data is returned numerically; accurate mileage algorithm, accuracy 99.5 %; support instantaneous fuel consumption, average fuel consumption and fuel consumption data; support vehicle fault code diagnosis, two commands can complete the reading and clearing of fault codes; modular design, high integration; vehicle-level anti-interference design; The hole and pin dual interface design meets all applications; the AT command set is simple and easy to use; it greatly improves the secondary development efficiency and shortens the development cycle.
The car network OBD module uses stamp/pin two different ways to connect various in-vehicle devices through UART, and obtain various data of OBD. It still uses dual-core processing, one MCU is responsible for decoding, one is responsible for calculation, and all data is already Analyze the good data, adopt the program without knowing any knowledge about the car protocol, and make the interface OK by circuit connection.
Principle analysis: EST527 car network OBD module, collecting and recording starting time, end time, total fuel consumption (idle fuel consumption, running fuel consumption) single driving mileage, idle fuel consumption, driving fuel consumption, current fuel cost, current average Vehicle speed, current maximum speed, maximum speed and other driving behaviors and other data, commonly used speed, speed, water temperature, voltage, OBD fault code information, the data will be transmitted to the background through GPRS, will open the Chinese OBD fault code library for partners free of charge The API port of the APP application can query 12000 ($6.1277) multiple car OBD fault code information in real time.
GPS navigation application: This scheme combines the new generation of real-time road navigation, subverts the traditional navigation equipment, adopts EST527 module, directly displays the fuel consumption trajectory, and the fuel consumption of a certain section is clear at a glance, and timely feedbacks the corresponding speed map trajectory. Based on the EST527 module development software, the road conditions support most of the country's high-speed road condition information. When you look at the map when traffic jams, you will know your congestion location and road condition interface. It is the best helper for road traffic information.
Cloud recorder application: We will capture the data collected by OBD according to the speed and speed of the vehicle, in case of collision, lock the data and send the car data and video data to the background in time. Combined with the big data medical rescue system, timely analyze the reasonable rescue plan. Reduce mortality.
Cloud GPS Locator: car chain tracking and intelligent anti-theft system, locking the car position and driving trajectory, can transmit information to mobile phone or computer through electronic fence, track car condition and geographical location information.
Internet of Vehicles Big Data: Integrate OBD+GPS+GPRS/CDMA/3G/4G, get car data, geographical location information, driving behavior habit data, automotive OBD intelligent fault diagnosis, CRM system, platform interaction and sharing, change driver's driving habits Enjoy life and entertainment information, provide maintenance, insurance services, set up repair stations on key road sections, gas stations, living places, rest stops, etc.
