A device for control of location of lifting vessel relates to the means of receiving information about displacement and location of moving objects and can be used in the systems of control of conveying machinery and protection thereof. The device contains a unit of reception of information and unit of transmission of information which consists of two proximity sensors located on the vertical wall of the lifting vessel. In the unit of reception of information two registers, a commutation switch, two digital indicators, a microcontroller, a diode, the first switch, a stabilitron, a condenser, receiver of radio signals and two buttons are introduced. In the unit of transmission of information a transmitter of radio signals, the second switch, a sparkproof electric power source and an element OR are additionally introduced. The device ensures widening functional possibilities by means of control of movement direction, speed and location of lifting vessel that enlarges field of application and also decreases costs of installation and operation. |
