  • The application host also needs to be indicated to the DataLogger.
  • To configure this information, access the DataLogger using an external device with WiFi communication.
  • Fill in the required details and click on Submit for the device to restart and connect to WiFi if available.
• Host Application:
  • All data generated by the devices is sent to the database through the application’s web service.
  • The web service is a REST API developed in C# language in .NET Framework 4.6, and it uses Entity Framework 6 ORM for data persistence.
  • The project also contains a front-end developed in the Vue.Js framework, using Vuetify as a component library.
  • The Front-End is served together with the Back-End application.

Introduction

1. The DaVinci Datalogger IIoT system is designed to collect and record events from sensors. The main objective is to expand scanning coverage at assembly stations on production lines.
2. The hardware has a unique programming and interface for the integration of sensors according to demand, being managed through a web service for the distinction and selection of which sensors will be enabled, parameters of limits for collecting the log, as well as basic setup of identification as “local”, “line”, etc, by the device serial.
3. The operation of the system depends on the correct integration between the  Hardware (datalogger) and the Software (service). When the hardware starts up, it connects to the network via WiFi (2.4GHz) and searches the system’s API for the settings determined to continue its setup.
4. Each device has a serial (unique) in its memory, which operates as a relationship key in the databases, linking the logs to locations, assembly stations, areas, and a specific function.

Product Specifications

Installation Requirements

• Mains 127v~220v AC.
• WebService installed and configured.
• Access to WiFi 2.4Ghz with a minimum power of -77 dbm, on a network that has access to the application’s web service.

Electrical power cable

Cable in NBR 14136 standard for AC 120~230v connection.

1. Led Online
   • Indicates that it is connected to the 2.4GHz WiFi network according to the setup performed in AP mode. It will also light up if you have the AP mode enabled, but in that case the display will keep showing only the DaVinci logo.
2. Led Data
   • Flashes green whenever a record is successfully saved.
   • Note that the led will only flash when receiving the “200 – OK” or “204 – No Content” response from the server, indicating the event was registered, therefore it should not be used as an indicator of the existence or not of a signal in the IO ports.
3. Display
   • The display will show the basic information regarding the registration in the system for that device. Device identification information is critical to understanding the generated data, and each saved record has these values as well.
   • The first line of the display shows the SERIAL of the device. This value is the unique identification of a DataLogger.
   • The second line will bring LOCAL – POSTO – SIDE identification information registered in the web interface for the indicated serial. This way we can visually guarantee that the information is being registered according to the place where it is installed.
4. RFiD Connector
   • Connector for connecting a 13MHz RC522 antenna.
   • Simply connect the antenna leads to the ports indicated by the DataLogger legend.
   • It is necessary to initialize the device with the antenna properly connected. If it is necessary to remove and/or reconnect the antenna, the device must be rebooted.
   • Whenever the antenna recognizes the approach of a valid RFID tag, the
   • DataLogger will record the tag reading in HEX format.

First Setup

• The application setup must be done initially on the device to configure the WiFi credentials and the application host.
• In the sequence, the other parameters will be indicated directly in the web interface.

WiFi and Hostserver setup

• The DataLogger device stores the credentials of the WiFi network where it must connect for communication with the application host, which also needs to be indicated to the DataLogger.
• To configure this information, it will be necessary to use an external device with WiFi communication to access the DataLogger by proximity (a notebook, cell phone, tablet…).
• The DataLogger starts up immediately when powered, and if it cannot access the WiFi or the server host, the device becomes an Access Point that will provide the SSID “DaVinci – 00000” where the numbers “00000” are unique for each device.
• Using another device, access the network that was created by the DataLogger, and through a browser go to the address “ 192.168.4.1” to view the page below:
• On this screen, fill in the fields with the SSID/Password information for the available WiFi network.
• If you need to use a static IP, fill in the appropriate fields or leave it as 0.0.0.0 (IP and gateway) for operation in DHCP mode. In the BaseURL field, type the base address of the web service and its respective port in ServerPort.
• The local IT may request the MacAddress for authentication of the DataLogger on the network, and for that, it will be enough to provide the code indicated in the last line of the page.
• At the end of filling, just click on Submit for the device to restart and connect to WiFi if available.
• The entered credentials are saved in the DataLogger indefinitely, regardless of the power supply.
• After the device connects in the WiFi network, it allows the visualization of its status, by accessing its IP in a web browser. It shows information about the device’s location, number of logs collected, and other Infos

Host Application

• All data generated by the devices is sent to the database through the application’s web service.
• It is a REST API developed in C# language in .NET Framework 4.6 and makes use of Entity Framework 6 ORM for data persistence.
• In addition to the API, the project contains a Front-End developed in the
• Vue.Js framework, using Vuetify as a component library.
• This Front-End is served together with the Back-End application.
