Development of automated monitoring safety system of the forklift DP 3510

Abstract

In this article, the problem of ensuring the safe operation of the forklift truck is analyzed, as well as the development of an automated monitoring system for preventing the occurrence of accidents in the territory of warehouses, enterprises and organizations using special transportation equipment. A model of the DLE system has been developed: Truck loader driver (D), Auto-loader (L), Environment (E). Hazard sources during loading operations are identified. Based on the analysis of the necessary and sufficient conditions for the transition of system states, an instrumental security assessment model has been developed that is used in the synthesis of a finite state machine. A ladder circuit and a forklift driver's console have been developed, implemented on the Omron software and hardware system. The developed onboard computer for the forklift truck takes into account the load of the mechanisms when lifting the load and, if it is necessary, generates an alarm or blocking mechanisms in a dangerous situation.
