Description

Purpose. The stand-tablet is intended for carrying out a set of theoretical works to study the design and operating principle of the KAMAZ engine starting aid systems of PZD and EFU trucks, the principles of their functioning and operating modes, as well as the formation of initial skills in vehicle maintenance and repair in the courses “Design automotive equipment”, “Operation of automotive equipment”, “Design and calculation of automotive equipment”.
Description. The stand-tablet should be a frame structure, on the front panel of which there is a schematic diagram of the systems for facilitating the starting of the KAMAZ engine of PZD and EFU trucks. The design on the front panel must be protected from damage when using the stand using the lamination method. The tablet stand must include: frame structure (PVC profile no more than 90 mm wide, HDF no more than 3 mm thick, PVC film with a full-color image of the diagram and elements of the KAMAZ engine start-up assistance systems of PZD and EFU trucks, with a resolution of at least 1400 dpi, a set of suspensions, an electronic logic device — an ADCS-P-4 controller, magnetic sensors, a complex of LED indications of fluid flows, electricity and components of the PZD and EFU systems); remote magnetic signal supply device. To implement educational goals for studying the design and principle of operation of the diesel internal combustion engine systems of a truck, the stand must be equipped with magnetically controlled contacts located under the front panel in the area of ​​​​each device (device), as well as under the image of the stand menu buttons. The exact location of the magnetically controlled contacts is determined by the colored circle marked on each device of the battery injection system. LED indicators should be placed on the front panel in the area depicting the flow of liquid, electricity and the components of the PZD and EFU systems, as well as in the places where magnetically controlled contacts are installed on the front panel. The operating algorithm of the stand must be implemented by a control module on a PIC controller. The electrical circuit of the stand must be powered by a standard switching power supply. The power cord connector and power supply switch must be installed on the side panel of the stand. At the bottom of the front panel, in order to implement the training and control function, there should be an image of the stand menu buttons and light banners “CORRECT” and “INCORRECT”.
