The KPP-2 on-board computer

The KPP-2 on-board computer was designed to integrate the information display controller with a vehicle operating parameter recorder. The work of an experienced team of designers resulted in the creation of a technologically advanced central unit that manages all elements of the passenger information system and records various events transmitted by the vehicle’s electronics.

One of the primary functions of the KPP-2 computer is to control electronic information displays, ticket validators, and ticket machines. The device also enables counting passenger flows, controlling mobile video and audio recorders, emitting voice announcements, and locating vehicle positions. Another important feature of the KPP-2 computer is the execution of journeys based on timetables planned by the carrier. Schedules for the entire fleet are created using dedicated software and delivered to the device via radio. From the user’s perspective, all that’s required is to create a single data packet, which is then distributed to the entire fleet.

The KPP-2 also allows for reading and recording all types of information about the vehicle’s status. The device is equipped with a range of interfaces that communicate with the vehicle’s electronics via a CAN bus and digital, time-of-day, pulse, and analog signals.

These solutions enable the recording of user-selected parameters, such as fuel consumption, energy use, rapid acceleration and braking, distance traveled, speeding, door opening time, and many others. All collected information is saved in the computer’s internal memory (Compact Flash card) as a specially formatted file. These messages can be read using dedicated software that processes files downloaded from the KPP-2 and presents them in reports. This ensures that all data contained in the controller is secured and accessible only to authorized users. Files are delivered from the KPP-2 to the user’s computer automatically via appropriate software and hardware.

The KPP-2 on-board computer is also a crucial link in the Dynamic Passenger Information System. It provides essential information about the vehicle’s current location and the time it will take to reach a specific stop. This information is used to update arrival and departure times on electronic bus stop displays.

A similar situation occurs when traffic light priorities are determined, also known as the “Green Wave.” An additional advantage of the device is its compact design. Unlike many devices available on the market, the computer we present here is designed as a single unit. The KPP-2’s small size allows it to be integrated into the vehicle’s dashboard, allowing all cables to be connected in one place.
