Abstract: A safety monitoring device of an elevator system having a shaft extending over at least two floors has a safety circuit with door contact switches being closed or opened accordingly when a respective shaft door is closed or opened. The door switches form an electrical series circuit that is electrically broken to block the elevator car from moving when any of the door switches is opened. The monitoring apparatus has at least one bypass switch that actuates a first door switch for a first shaft door on a first floor such that, when the elevator car reaches the first floor, the bypass switch bypasses the first door switch to switch the safety circuit independently of the first door switch. A monitoring means of the monitoring apparatus monitors the switching state of the safety circuit and/or of a second door switch for a second shaft door on a second floor.

Abstract: An elevator car load measurement system for determining a load of an elevator car includes a plurality of at least two force sensors that are daisy-chained and connected to a controller for determining the load. Each force sensor measures a force exerted by the elevator car on the respective force sensor and generates a frequency signal with a square-wave form, wherein the frequency signal is proportional to the respective measured force. At least one of the force sensors adds a first frequency signal received from the previous force sensor along the daisy chain a second frequency signal generated by the at least one force sensor to generate a frequency sum signal, the last of the force sensors in the daisy chain forwards the frequency sum signal to the controller.

Abstract: A control device controls an elevator system in inspection mode, the elevator system having a safety circuit with at least one safety contact that is open in inspection mode and an inspection path for bridging the safety contact. The control device includes first and second operating elements for controlling the inspection mode and first and second switching units connected in parallel and each having a contact associated with a delay means. The switching units close and open their contacts in response to actuation and release of the first and second operating elements respectively. The contacts are series connected in the inspection path. The first and second delay means delay opening of the associated contacts by defined delay times after the release of the first and operating element respectively.

Abstract: An elevator system has a central control unit for generating control signals and/or processing sensor signals and controlling functions of the system, a plurality of field devices distributed inside a structure accommodating the system, preferably along an elevator shaft, and a field bus system for interchanging the signals between the control unit and the field devices. Each field device outputs sensor signals generated by a sensor and/or receives control signals to be implemented by an actuator. Data packets including the signals are interchanged in a serial manner between the control unit and all field devices in a summation frame method using a closed ring topology. Each field device has a driver to insert the sensor signals into the data packet or to remove the control signals from the data packet. Data and signal transmission is thereby carried out quickly and safely in a safety circuit of the elevator system.

Abstract: A method for controlling a maintenance mode of an elevator system includes: recognizing a machine-detectable feature in an automated manner using a portable computer-controlled device of a technician and, subsequently, outputting a maintenance completion signal, the machine-detectable feature being within the elevator system such that it can only be detected by the computer-controlled device located outside an elevator shaft of the elevator system and wherein the machine-detectable feature is uniquely assigned to the elevator system; receiving the maintenance completion signal by an elevator controller controlling the maintenance mode and, subsequently, completing the maintenance mode. The method and an elevator control arrangement configured to carry out the method enables a maintenance mode to be completed by the technician in the elevator system in a simple, intuitive, and safe manner without the need for significant additional hardware.

Abstract: An elevator control cabinet used in an elevator system includes a voice communication apparatus having a microphone, an electronic control arrangement, an evaluation unit, and a cabinet housing having at least one cabinet door. The voice communication apparatus is used to execute a service or emergency call or establish a communication between the elevator and a public communication network. The microphone detects a surrounding noise in the control cabinet. The evaluation unit converts the detected noise into a noise pattern and then compares this noise pattern with a reference sound pattern that is predetermined for a surrounding noise in the cabinet housing with the open or closed cabinet door. This reference sound pattern is saved in a storage unit of the control arrangement. In dependence on a result of the comparison, the evaluation unit will recognize whether the cabinet door is open or closed.

Abstract: An elevator system inspection control system and method for switching between normal and inspection operating modes includes a safety chain series circuit having at least one shaft or door contact switch and an operating device in an elevator shaft. The operating device includes a changeover switch for switching between modes. The safety chain is closed to drive an elevator car by establishing a current path between an electrical power source and a motor. When interrupted, the safety chain interrupts the current path thereby stopping the car. The control system includes a manual switch outside the shaft and a control element. The safety chain is closed or interrupted by activating or deactivating the control element while the current path to the motor remains permanently interrupted until the manual switch is actuated when the changeover switch switches the elevator system from the inspection operating mode to the normal operating mode.

In inspection mode, car is manually controlled by operating device via electric motor, wherein elevator system is switched to normal mode or inspection mode by switch of operating device. Inspection control system also includes: detection device for detecting open and/or closed shaft door, alarm generator, operating switch for activating and/or blocking electric motor, control unit that monitors switching state and actuation sequence of switch and emergency stop switch and compares both with reference switching state and reference sequence with regard to detected state of shaft door.

Abstract: A position-determining system and a method for ascertaining a car position of an elevator car use a code tape mounted next to the elevator car in parallel with a movement direction and that includes a code-mark pattern of individual code marks, a detection apparatus mounted on the elevator car that detects the code marks, and an evaluation unit that determines the car position on the basis of the detected code marks. Here, n successive code marks of the code-mark pattern form a position mark, the position marks are unambiguously arranged in an n-digit pseudorandom sequence of various position marks, the position marks form a single-track code-mark pattern, and a discrete car position is assigned to each position mark. A detection region of the detection apparatus has a detection length in the movement direction that is shorter than a position-mark length of a position mark in the movement direction.
