SELF-CONTAINED HOISTING MACHINE PARAMETRE RECORDER Russian patent published in 2010 - IPC B66C13/18 

FIELD: transport.

SUBSTANCE: invention relates to self-contained hoisting machine parametre recorder. Proposed recorder comprises operating parametres, transducer, microcontroller-based digital computer and real time counter incorporated with said microcontroller or made as a separate circuitry connected to real-time counter power supply output terminals. It comprises also memory device connected to digital computer or incorporated therewith. Note that said operating parametres transducers are connected to microcontroller either directly or via extra matching device. Said microcontroller can receive and process signals of said operating parametres transducers and enter them into aforesaid memory as well as real-time-counter signals. Recorder can transmit data from said memory to external read-off device and/or display said data on monitor. It incorporates also self-contained power supply voltage control device made either independent or incorporated with aforesaid microcontroller. Digital computer can process signals coming from self-contained power supply voltage control device and record appropriate attribute of voltage drop in memory or microcontroller memory to read off said attribute by external read-off device. Supply lines of all components of proposed recorder are connected to self-contained power supply.

EFFECT: continuous recording of machine operating parametres irrespective of availability of voltage in elevator onboard circuit.
