How to Store and Visualize CAN Bus Telematic Data with InfluxDB Cloud and Grafana

Download to read offline

CSS Electronics develop & manufacture professional-grade, simple-to-use CAN bus data loggers. Their plug-and-play CANedge2 logger records time-stamped raw CAN data to an extractable industrial SD card — and connects via WiFi/3G/4G access points to upload the data to the end user’s own servers. The CANedge2 is ideal for collecting automotive sensor metrics like speed, temperatures, state of charge, GPS and more. Learn how to create your own telematics dashboard built on InfluxDB in minutes by attending this webinar!

Join us as Martin Falch dives into:

CSS Electronics’ approach to improving R&D field testing, diagnostics, fleet management and predictive maintenance
The CANedge’s methodology for collecting IIoT data from cars, trucks and machines
How they process time series data from S3 via Python to store it in InfluxDB and visualize it with Grafana

  6. 6. what is CAN bus? ● Quick overview of the technology ● Where is CAN bus used? ● Raw vs decoded CAN bus data CAN Bus Explained CSS Electronics, CAN bus and the CANedge2
  7. 7. where is CAN bus used? CSS Electronics, CAN bus and the CANedge2
  8. 8. raw vs decoded CAN bus data CSS Electronics, CAN bus and the CANedge2
  9. 9. example: What challenge do we solve? Situation ● Forklift battery OEM needs to collect data from new prototype ● Data to be recorded across hundreds of units & multiple warehouses CSS Electronics, CAN bus and the CANedge2
  10. 10. example: What challenge do we solve? Complication ● Because this is a team of OEM engineers, they have very specific requirements to the product ○ Solution needs to be low cost due to scale ○ Needs to be plug & play to install + power-safe ○ Needs to be pro specs - e.g. 0.05 ms frequency ○ Needs to be configurable (filters, triggers, ...) ○ Need to auto-upload data to their own server ○ Needs to be able to securely upload via WiFi ○ Needs ‘zero loss’ - SD is required to buffer ○ Needs support for many different software tools ○ ... CSS Electronics, CAN bus and the CANedge2
  11. 11. example: What challenge do we solve? Solution ● The CANedge2 enables the OEM to achieve their required use case CSS Electronics, CAN bus and the CANedge2
  12. 12. about the CANedge2 ● bit.ly/canedge2 ● bit.ly/canedge-intro-video ● www.csselectronics.com ● contact@csselectronics.com ● +45 91 25 25 63 CANedge2 2x CAN/LIN Data Logger (SD + WiFi) The 2xCAN/LIN logger records timestamped CAN bus data (Classical/CAN FD) to the extractable 8 GB industrial SD card. The device connects via WiFi access points (e.g. WLAN or 3G/4G routers) to securely push data to your own server. Ideal for telematics, field tests, diagnostics, predictive maintenance. CSS Electronics, CAN bus and the CANedge2
  13. 13. how it works ● Set up your own S3 server (~5 min) ● Configure your CANedge2 with your server/WiFi details ● Connect it to your CAN bus application to start logging ● Data is auto-pushed to your server and can be processed via the free software/API tools and DBC files CSS Electronics, CAN bus and the CANedge2
  14. 14. example use cases CSS Electronics, CAN bus and the CANedge2
  15. 15. what makes our solution different? ● Cross-section between pro specs loggers and telematics ● Ease-of-use: Plug & play & highly configurable (without scripts) ● Low cost: 50-80% lower cost vs. comparable devices ● Interoperable: Utilize open standards to ease custom integration ○ JSON Schema (configuration) ○ S3 (server interface) ○ MF4 (standardized binary log file format) ● 100% free open source software (FOSS) ● We do not host anything (and charge no recurring fees) pro specs automotive data loggers vehicle telematics CSS Electronics, CAN bus and the CANedge2
  16. 16. Telematics dashboards via InfluxDB and Grafana
  17. 17. issue: We lacked browser data visualization The CANedge2 integrates with various software tools - but previously no dashboard solution: ● Configuration editor: Load & edit JSON config files ● MF4 converters: Convert log files to other file formats ● asammdf: View, edit, DBC decode, plot log files ● Python API: Load & DBC decode log files ● CANcloud: Manage CANedge2 devices & data Telematics dashboards via InfluxDB and Grafana
  18. 18. how to best create a dashboard integration? Challenge Our users wanted to visualize their CAN bus data in the browser - ala a classic telematics dashboard Complication Specific user requirements: ● Need intra-second frequency ● 100% panel customization required (with no coding) ● Setup has to be really easy ● Solution needs to be optionally 100% free & open ● Should scale for big data Solution Process log files via Python API, write decoded data to InfluxDB, visualize in Grafana (facilitated via step-by-step guide and plug & play scripts) Telematics dashboards via InfluxDB and Grafana
  19. 19. why Grafana and InfluxDB? Why Grafana? ● Very popular (41K+ github stars) ● Intuitive/easy front end customization ● 100% free and open source ● Optional cloud (incl. free starter) ● Many plugins incl. geo maps ● Easy support for variables, alerts Why InfluxDB? ● Very popular (21K+ github stars) ● Natively supported by Grafana ● 100% free and open source ● Optional cloud (incl. free starter) ● Grafana & Influx Cloud Starter = easy ● Simple-to-use Python write API ● Intuitive explorer functionality Telematics dashboards via InfluxDB and Grafana
  20. 20. how did we implement it? ● High level article to explain concept and possibilities ● Our users need to be able to set everything up themselves ● “Time-to-awesome” is key - start simple! (free starter cloud) ● Optimized step-by-step guide with sample data + DBC ● Each device = ‘measurement’, each parameter = ‘field’ alternative setup examples typical ‘proof of concept’ setup Telematics dashboards via InfluxDB and Grafana

  26. 26. pros & cons of the implementation Telematics dashboards via InfluxDB and Grafana Pros ● Easy to get started due to cloud starters and plug & play data/script ● 100% free & open source - or paid convenience via full/partial cloud ● Users can fully customize their solution - without being developers Cons ● Our devices push data to S3, so an “S3 data source” would be “cleaner” (avoid duplicate data storage) ● Periodic uploads can result in users needing to crunch several GB at once ● Flux support in Grafana still semi-new
