BusLogic IO modul


BusLogic Input / Output moduleis a device used for analog and digital vehicle parameter reading. This device can read all the analogue data from all of the older vehicles (buses and trucks) about the current number of engine RPMs, fuel tank level status, engine temperature, vehicle door positions, position of trailers etc. In addition to analogue signals the device also supports digital readings over the CAN protocol. All information that BLIO module receives, either analogue or digital, are transmitted to the BLM module via GPRS that further transmits all stored data to a central server. Another function of this module is to remotely run certain events in a vehicle such as closing doors, powering on displays or monitors, etc. With the assistance of BLM, the BLIO module sends the information about a particular event that occurs inside the vehicle. One of the main features of this option is to change the status of transmission from economical driving to uneconomical when the vehicle is to climb a slope and vice versa, shift between urban or interregional drive which enables savings in fuel consumption while eliminating error of the human factor.

The BLIO module is very popular with bus transporters, because with the help of this device clients get the information of driving style per driver. Through generated reports, clients can actually see a chart for the driver, how long he drove and in which zone: green-economical or red uneconomical, and how many times he went into the red zone. In this way, the user of the system saves more fuel, thus reducing consumption and increasing profits. What is even more important, all this above extends the life expectancy of the vehicle and reduces the need for servicing. In addition to measuring engine’s RPMs, it is important to highlight measuring of the fuel level in the reservoir and device’s ability to alarm the user if there is a drastic fall in the level of fuel in the reservoir for a short time, usually caused by unauthorized extraction of fuel from the tank or a major vehicle malfunction – either requiring user’s attention. Also the I/O module can alert users via DLM when a vehicle engine is overheated, or if it has reached the critical temperature.
