Patent number: 11453570Abstract: Conventionally, elevator communications have been implemented using travelling cables. This is particularly the case when safety related data transmitted from an elevator car has to fulfil real-time restrictions often set by regulators so that the receiving of the information may not be delayed. Typically, this cannot be guaranteed when wireless transmission technologies are used. The reliability can be increased by using a second to supplement the wireless transmission.Type: GrantFiled: October 26, 2018Date of Patent: September 27, 2022Assignee: KONE CORPORATIONInventors: Ari Kattainen, Antti Hovi

Publication number: 20220297977Abstract: An elevator safety system includes an electronic safety controller running a software including a monitoring mode for monitoring the position of an elevator car within a hoistway. The system includes a position measurement device for measuring the elevator car position. There are limit position identification markers being installed in the hoistway for defining a starting point of a final movement zone in which the car is still allowed to run in a direction to the outermost ends of the hoistway. However, as soon as the end of the final limit zone is reached by the car, an emergency stop is triggered. The position data for the final limit zone are laid down in a memory of the safety controller as parametrized data for being able to adjust them if so needed. Therewith, it can be avoided that the hardware components in the shaft have to be replaced.Type: ApplicationFiled: June 7, 2022Publication date: September 22, 2022Applicant: KONE CorporationInventors: Ari JUSSILA, Atso KOSKINEN, Tommi VAINIO, Toni HIRVONEN
