gideonvos: GPS, IoT, Blockchain Integration to ERP
Источник: https://gideonvos.wordpress.com/2017...ration-to-erp/
==============

I’ve read a number of articles discussing how Blockchain could have a significant impact on Trade & Logistics, especially item tracking. Granted, Blockchain is not a requirement for shipment tracking, but it does deliver a number of benefits through being a shared, secure ledger that, depending on the network, could provide an automatic openness almost immediately. That is a vast improvement over building a custom customer and partner portal to query legacy backend systems.

Of course, there remains the problem of now having to integrate Blockchain into your legacy ERP system, a whole different level of headache. So, in this post I’m going to do a simple POC to simulate how easy, or hard, it would be to build an item tracking service using Ethereum Blockchain, add to that GPS tracking with temperature and humidity monitoring, and get that to your ERP system, in this case Microsoft Dynamics 365. I want to achieve that without modifying the ERP system in any way, by using Microsoft Flow, a PowerApp and Microsoft Common Data Service. The idea is that end users, customers or partners can use the PowerApp to monitor shipments and climate conditions in real-time. Supply-chain visibility every step of the way, basically.

To start, I built a simple IoT monitoring device around the Adafruit Huzzah. I’ll be using WiFi here, making a wild assumption that WiFi is available wherever this device goes. In the real world, GPRS or Loran might be more suitable, but I don’t have that available in my toolkit just yet and besides, this is an experiment only. I’ve added a low-cost GPS, DHT11 temperature and humidity sensor, and an LCD screen to show me what is happening without requiring connecting to my laptop via the serial interface. The basic IoT device is shown below, with GPS and DHT-11 working and transmitting data.



The C code for the IoT device is shown below. I do a POST to my Ethereum network of choice with hardcoded addresses, and embed the GPS coordinates and DHT11 state into the data portion of the Ethereum transaction. Addressing and data is entirely up to you; perhaps instead of hardcoding, this can all be read off an SD card.
