Definitions

  • the invention relates to a sensor device for controlling the elevator door of an elevator depending on the detection of the passage to the elevator car and an anteroom in front of the elevator car.
  • the sensor device is a sensor device for an elevator with a car with an elevator door, which has a door movement space in the passage and which is preceded by an anteroom area on the floor in front of the door movement space.
  • the sensor device has a detection device which is designed for the separate detection of objects in the door movement space and in the anteroom area and for carrying out successive detection runs.
  • the sensor device has an evaluation device which has a memory. The sensor device is designed to at least temporarily store in the memory the information as to whether an object was detected during a detection run. It is irrelevant whether the object was detected in the door movement area or in the anteroom area.
  • the sensor device is designed to output an early closing signal for closing the elevator doors if no object is detected during a detection run and the information is stored in the memory for a previous, in particular for a specific previous, in particular for the immediately preceding detection run, that a object has been detected.
  • This sensor device can have the advantage that the elevator doors can be closed more quickly with the early closing signal. This means waiting times can be shortened and the elevator can be operated more effectively.
  • the early closing signal only occurs under certain conditions, namely when it is ensured that no person has previously been in the direct area of the elevator door, i.e. in the door movement space together with the anteroom area, for a sufficient period of time prevent people from being frightened by a surprising closing process.
  • the ease of use can therefore be increased.
  • An elevator door is generally a sliding door.
  • An elevator door can be a single-leaf or a double-leaf sliding door.
  • the sliding door can be solid or telescopic.
  • the door movement space is the space that the front edge of the elevator door or doors covers during the closing process.
  • Separate detection means that the detection of an object can be assigned to the door movement space or the anteroom area.
  • a memory means any possibility of accessing information from the past, although here generally only a temporary memory is sufficient to previously monitor a certain period of time.
  • This can be implemented electronically in any form, for example via a main memory, RAM, a register, but also, for example, a flip-flop circuit or another circuit with which information can be temporarily stored.
  • the evaluation device is preferably designed to output an opening signal for opening the elevator doors when an object is detected in the door movement space.
  • the evaluation device is preferably designed to output a conditional closing signal for conditionally closing the elevator doors if no object is detected in the door movement space.
  • Conditional closure means that the elevator doors should be closed when a certain amount of time has elapsed since an opening signal to open the doors.
  • the evaluation device preferably has a timer and is designed to start the timer when an object is detected in the door movement space and to output a closing signal to close the elevator doors if no object is detected in the door movement space and at the same time a certain time period of the timer has expired is.
  • conditional closing signal and the opening signal are inverse to each other, and in particular one of the two signals is given by the absence of the other signal and in particular the conditional closing signal is defined by the absence of the opening signal, or vice versa, and in particular the opening signal is the high state and the conditional closing signal of the low state on the same signal line.
  • conditional closing signal and the early closing signal are different from one another and, in particular, are neither equal to nor inverse to one another and, in particular, are transmitted via different signal lines.
  • the control system is a control system for an elevator with a car with an elevator door, which has a door movement space in the passage and which is preceded by an anteroom area on the floor in front of the door movement space.
  • the control system has a detection device which is used for the detection, in particular for the separate detection, of objects in the door movement space and in the anteroom area and for Carrying out successive detection runs is designed.
  • the control system has a system controller which is designed to open the elevator doors when an object is detected in the door movement space and to start a timer when the elevator doors are opened and to close the elevator doors when no object is detected in the door movement space and at the same time a certain period of time on the timer has expired.
  • the system control has a memory and is designed to at least temporarily store the information as to whether an object was detected during a detection run and to close the elevator doors if no object was detected during a detection run and at the same time in the memory for a previous one, in particular for The information that an object has been detected is stored in the immediately preceding detection run.
  • the control system according to the invention can contain the sensor device according to the invention.
  • the door movement space essentially corresponds to the plane between the cabin doors and the shaft doors and in particular to the detection plane of a conventional light grid.
  • the duration of the timer is preferably 5 seconds.
  • the object is a person.
  • the detection device is preferably arranged on the transom of the passage and/or surrounded by a housing, in particular together with the evaluation device.
  • the detection device comprises a 3D sensor, in particular a TOF 3D sensor, and in particular has a sensor matrix, with an area of the sensor matrix being used for detection in the door movement space and another area of the sensor matrix is assigned to detection in the anteroom area.
  • Fig. 1 shows a control system 10 according to the invention with a sensor device 10 and a door control 40 for an elevator.
  • the elevator has a car with one or two elevator doors.
  • the elevator doors move in a door movement space in the passage.
  • the door movement space is essentially the space between the opened passage from the floor to the interior of the elevator car, which is covered by the door edges when closing.
  • In front of the door movement room is a vestibule area on the floor.
  • the vestibule area is essentially a space area in front of the door movement space outside the cabin, which is defined by the detection device and which extends, for example, 2 meters in front of the door movement space.
  • the sensor device 20 is arranged on the elevator car in the area of the fighter.
  • the fighter is the upper, horizontal area of the doorway.
  • the door control 40 is arranged in the shaft or machine room and connected to the sensor device via a hanging cable from the elevator car.
  • the sensor device 20 sends either an opening signal 31 or a conditional closing signal 32 to the door control 40.
  • the conditional closing signal 32 is given by the absence of the opening signal 31.
  • the sensor device 20 can send an early closing signal 33 to the door control 40.
  • the sensor device 20 has a detection device 21. This is a 3D TOF sensor and consists of a sensor matrix, optics and IR lighting.
  • the detection device is designed to monitor two areas. The first area is the door movement space. The second area is the anteroom area.
  • the sensor device 20 comprises an evaluation device with a first discriminator 22, a memory 23, a second discriminator 24 and a third discriminator 25.
  • the sensor device 20 When the elevator car has arrived in a stopping position and the doors are at least partially opened, the sensor device 20, like a film camera, periodically undergoes detection runs in which it detects the two rooms and evaluates the detection in each case. In each detection run, the detection device 21 takes an image of the door movement space and the anteroom area.
  • the first discriminator 22 accepts the data from the detection device 21 via the data connection 21a, evaluates it and if an object was detected in the space between the doors, then it outputs an opening signal 31 and writes the detection of an object into the memory 23.
  • the second discriminator 24 evaluates the data from the detection device 21 and if an object was detected in the anteroom area, then it outputs a conditional closing signal 32 and writes the detection of an object into the memory 23.
  • This Conditional closing signal 32 is the absence of the opening signal.
  • the memory stores the fact whether an object was detected in the current detection run until the next detection run. If no object was detected in the anteroom area, the third discriminator 25 evaluates the memory 23 and also sends the conditional closing signal 32 if the memory does not contain the information that an object was detected in the previous detection run, or sends out an early closing signal , if the memory contains the information that an object was detected in the previous detection run.
  • the door control 40 receives either the opening signal 31, the conditional closing signal 32 or the early closing signal 33 from the sensor device 20.
  • the door control 40 receives the opening signal 31 via the connection 31a, then the door control causes the elevator door to open and starts a timer 42.
  • a discriminator 43 evaluates whether a certain amount of time has passed since the start of the timer 42 and outputs a closing signal 44 and closes the elevator doors if since the start of the Timer 42 the certain amount of time has passed.
  • the specific time period is 5 seconds, but can also be longer or shorter.
  • the connection 31a for the opening signal 31 and the connection 32a for the conditional closing signal 32 is the same signal line.
  • the conditional closing signal is the absence of the opening signal on the same signal line.
  • the door control 40 receives the early closing signal 33 via the connection 33a, then the door control 40 closes the elevator doors immediately.
  • the early closing signal 33 is transmitted via a different signal line than the opening signal 31 and the conditional closing signal 32.
