Logger eases mobile acquisition of operating data


IPEfms is a data logger for mobile acquisition of operating data in fleet testing and provides capabilities for collecting and storing a vehicle’s operating data and then transmitting it continuously to a data server via General Packet Radio Service (GPRS) and the Internet.

Besides the operating data prescribed in the Fleet Management Systems (FMS) interface standard, the on-board diagnostics (OBD2) data and digital tachograph (DTCO) data are also recorded.

In addition, the data logger from Ipetronik captures the vehicle’s route using Google Maps. The preview and further processing of the measurement results that are collected on the data server can be customized to meet specific requirements.

The data logger is equipped with two CAN bus inputs with baud rates of up to 1 MBit/s, two digital inputs, and a digital output. These features are joined by a GPRS modem (quad band) for transmitting data to the server, and by a Bluetooth 2.0 port with enhanced data rate (EDR) capabilities for transferring data within close range.

A GPS receiver is installed for positioning capabilities via satellite. It is possible to activate the data logger using a wake-on-CAN function. All parameters for data acquisition – such as the format, sampling rate, memory depth, etc. – are defined on a project-specific basis in the firmware. Users can access the information from their desk/workplace via a webserver.

This compact data logger is housed in a powder-coated aluminum enclosure with an IP30 protection rating and dimensions of 120 x 30 x 100 mm (W x H x D). The enclosure has no parts that move mechanically (such as a ventilator fan, hard drive, etc.). The logger operates in a temperature range from –40 °C to +85 °C at a relative humidity of 15 to 90 percent. The power supply is provided via the 12/24 V DC vehicle electrical system. The typical power consumption is 1.5 watts.
