Single Board Computer in Portable Gas Analyzer

The computational and control system forms the core of a portable gas analyzer. This system is responsible for receiving sensor inputs, processing data, controlling device operations, displaying results, issuing alerts, and sharing data, among other functions. In other words, without this system, the analyzer would be unable to function properly. However, this system needs to possess powerful performance, exceptional stability, and abundant interfaces to fulfill its tasks. In reality, computing systems that possess these characteristics tend to be bulky and high-power, making them unsuitable for integration into portable devices. Therefore, a small-sized, high-performance single board computer (SBC) is exceptionally well-suited for portable gas analyzers.


In a portable gas analyzer, the single board computer (SBC) can play a significant role, including the following aspects:


Data Processing and Analysis: The primary function of the SBC is to serve as the core processing unit, executing all computational tasks. In a portable gas analyzer, the SBC receives various measurement data from sensors and processes, analyzes, and decodes them. The SBC then displays or transmits the interpreted information, such as gas type and concentration, to other devices. This process requires powerful computational capabilities and stable performance, particularly with high demands for real-time and accurate results.


Control and Configuration: In addition to data processing, the SBC is responsible for controlling various components of the analyzer, including sensor activation and deactivation, adjusting their operating status as required, managing power consumption, and more. Users can also configure the device using the SBC, such as calibrating sensor parameters and setting measurement thresholds.


Network Connectivity and Data Sharing: Modern portable gas analyzers often need to upload data in real-time to the cloud or other devices for data sharing and remote monitoring. The SBC typically integrates wireless network modules such as Wi-Fi or Bluetooth, allowing convenient data transmission to the network.


User Interaction: The SBC can be connected to various user interface devices such as LCD displays, LED indicators, touchscreens, etc., to visualize data and device status or receive user input. Some SBCs also support audio output through speakers, providing sound prompts and alarm functionalities for the device.


Therefore, the SBC plays a core role in portable gas analyzers, as its performance and expandability directly impact the device's efficiency and application range. When selecting an SBC for a portable gas analyzer, factors such as real-time data processing capabilities, size, expandability, network connectivity, and other considerations need to be taken into account.

Case Study - LattePanda 3 Delta in Intelligent Fire Alarm System


Fire gas analyzers are essential devices used for detecting fires by analyzing gases produced during combustion, such as smoke, carbon monoxide, and carbon dioxide. These analyzers promptly raise alarms, ensuring the safety of individuals and property.


Industry Challenges

Traditional fire detection methods, including smoke detectors, flame detectors, and temperature sensors, often sound alarms only after a fire has already occurred. However, these methods often fail to detect early signs of fires, resulting in significant property damage and human casualties. Therefore, there is a need for a portable device that can monitor gas concentrations in real-time and provide multiple dimensions of analysis to address this issue effectively.


Requirements for SBC Implementation

Simple microcontroller units (MCUs) are insufficient to support multiple sensor integration, high-performance sensor data processing, extended battery life, and robust system compatibility. A more powerful SBC is required to meet these demands.
