Case Study: Deployment of Bluetooth Components for Airpufying Equipment Management

I. Introduction

A. Background

The customer, a production company for food ingredients, had a key production facility with multiple airpufying equipment. The company was looking for a solution to manage the equipment, including the ability to preset parameters, save different sets of settings, check filters, trigger maintenance alarms, and produce usage and air quality reports.

B. Objectives

The objective of the project was to deploy Bluetooth components into the equipment and design a Server-Based System with a Web Interface and a Mobile Interface (PWA) to meet the customer's requirements. The solution needed to be user-friendly, scalable, and robust, allowing engineers to easily manage the equipment from anywhere.

C. Scope of Work

The scope of work included the design and implementation of the Server-Based System, the Web Interface, and the Mobile Interface (PWA). The solution needed to provide the following functionality:

  1. Preset parameters to turn the equipment on and off
  2. Save different sets of settings to cater to different situations
  3. Check the filters and trigger maintenance alarms
  4. Produce weekly and monthly usage reports
  5. Produce air quality reports
  6. View power consumption information

II. Solution Design

A. Server-Based System

  1. Architecture Overview

    The Server-Based System was designed to be the central repository of all data and information related to the airpufying equipment. The system was built using a robust and scalable architecture, allowing it to handle a large volume of data and concurrent users.

  2. Database Design

    The database was designed to store information such as equipment settings, filter status, usage reports, air quality reports, power consumption, and maintenance alarms. The following tables were created:

a. Equipment Information Table The Equipment Information Table stored information about each piece of equipment, including its unique identifier, location, and status.

b. Usage Report Table The Usage Report Table stored information about the usage of each piece of equipment, including the dates and times of usage and the duration of usage.

c. Air Quality Report Table The Air Quality Report Table stored information about the air quality in the production facility, including the air quality readings and the dates and times of the readings.

d. Power Consumption Table The Power Consumption Table stored information about the power consumption of each piece of equipment, including the power consumption readings and the dates and times of the readings.

e. Maintenance Alarm Table The Maintenance Alarm Table stored information about maintenance alarms triggered for each piece of equipment, including the date and time of the alarm and the type of maintenance required.

  1. Software Architecture

    The software architecture was designed to provide the following functionality:

a. Modules Overview The software was divided into modules, including a module for equipment management, a module for report generation, and a module for maintenance management.

b. Communication Protocols The system was designed to use Bluetooth for communication between the equipment and the server. The communication protocol used was based on the Bluetooth Low Energy (BLE) standard.

B. Web Interface

  1. User Interface Design The Web Interface was designed to be user-friendly and intuitive, allowing engineers to easily access and manage the equipment information.

  2. Functionality Overview The Web Interface provided the following functionality:

  1. Preset parameters to turn the equipment on and off
  2. Save different sets of settings to cater to different situations
  3. Check the filters and trigger maintenance alarms
  4. Produce weekly and monthly usage reports
  5. Produce air quality reports
  6. View power consumption information

C. Mobile Interface (PWA)

  1. User Interface

    Design The Mobile Interface was designed as a Progressive Web Application (PWA), allowing engineers to access the system from their mobile devices. The user interface was designed to be fast and responsive, providing a seamless user experience on mobile devices.

  2. Functionality Overview

    The Mobile Interface provided the same functionality as the Web Interface, allowing engineers to manage the equipment on the go.

III. Implementation Details

A. Server Environment

  1. Hardware Requirements

    The server was implemented using a high-performance server with enough storage and RAM to handle the expected volume of data.

  2. Network Environment

    The server was connected to the network using a reliable and fast network connection, ensuring that the data could be transmitted quickly and efficiently.

  3. Server Configuration

    The server was configured to ensure maximum security and performance, including the implementation of firewalls and other security measures.

B. Bluetooth IOT Device Management

  1. Coding Sample in C#

    The following is a sample of the code used to manage the Bluetooth IOT devices:

a. Connection Establishment

private async void ConnectToDevice(BluetoothLEDevice device)
{
    if (device == null)
        return;

    var result = await device.ConnectAsync();
    if (result == BluetoothError.Success)
    {
        var services = await device.GetGattServicesAsync();
        foreach (var service in services.Services)
        {
            var characteristics = await service.GetCharacteristicsAsync();
            foreach (var characteristic in characteristics.Characteristics)
            {
                // Do something with the characteristic
            }
        }
    }
}

b. Data Collection

private async void ReadDataFromCharacteristic(GattCharacteristic characteristic)
{
    if (characteristic == null)
        return;

    var result = await characteristic.ReadValueAsync();
    if (result.Status == GattCommunicationStatus.Success)
    {
        var value = result.Value;
        // Do something with the value
    }
}

c. Data Synchronization with Server

private async void SynchronizeDataWithServer(byte[] data)
{
    using (var client = new HttpClient())
    {
        var content = new ByteArrayContent(data);
        var result = await client.PostAsync("http://server/api/data", content);
        if (result.IsSuccessStatusCode)
        {
            // Data synchronized successfully
        }
    }
}

IV. Conclusion
