Founded in 1988, SGF is based in Peru and serves as a supplier of fleet management systems. At a time when the embedded electronics industry was embryonic, SGF developed the first on-board computer. SGF is now configured as a hardware manufacturer and develops motherboards for transportation and automation applications. A customerin the city of Lima was looking for an SI to implement a fleet management solution that would facilitate the city’s garbage truck fleet monitoring and waste management operations. They needed an in-vehicle solution that could monitor vehicle movements, diagnostics, and, crucially, driver behavior. After consulting numerous vendors, they elected to partner with Advantech. This is because Advantech offers a comprehensive range of flexible solutions that can be rapidly customized according to specific needs with support from their team of expert engineers.
SGF adopted Advantech’s TREK-723 mobile data terminal (MDT) for managing moving fleet assetsand driver behavior. Equipped with built-in GPS and CDMA/GPRS/HSPA+, TREK- 723 MDT enables drivers and dispatchers to maintain constant communication, and can be used to monitor data ranging from mileage, routing, speed, and acceleration, to braking, oil Application Story pressure, and fuel consumption. An important additional function the customer required was the ability to log driver behavior and routes to ensure compliance with city safety regulations. Advantech’s MDT was integrated with a reading device specifically developed by SGF to reduce tedious manual logging and tracking for more informed management that enhances waste management safety and efficiency.
To achieve real-time fleet management, a vehicle-mounted system with several specific features is required. In this case, the required features were WWAN communication, GPS, and a unique SGF-designed CAN bus-based reading module for reading vehicle data. Additionally, the system’s power supply, shock resistance, and core temperature range should be suitable for operation in harsh environments. In-vehicle computers should conform to several special requirements. For example, older trucks tend to have an unstable power supply, excessive noise, and insufficient voltage, which hinder system activation. When connected to peripheral devices, a sudden voltage surge can damage the motherboard, and bumpy roads may cause power outages or computer failures. Moreover, systems without a wide operating temperature range cannot perform consistently in extremely hot or cold weather. All these factors can lead to system fails, and, in worse-case scenarios, necessitate sending the system to the factory for repair.
