Definitions

  • the present invention relates to an apparatus for changing the operational mode of an elevator, as defined in the introductory part of claim 1.
  • Key switches mounted in the signal devices require more installation depth than pushbuttons and direction arrows. This causes difficulties especially in the case of surface-mounted devices, i.e. devices mounted directly on a wall surface without making a cut-out in the wall.
  • the installation of key switches involves extra work because they require separate mounting boxes.
  • the object of the present invention is to eliminate the drawbacks mentioned above and to achieve a simple and reliable apparatus for changing the operational mode of an elevator. This is accomplished by means of the characteristic features defined in the characterization part of claim 1. Other preferred embodiments of the invention are presented in the subclaims.
  • keys that are physically identical and fit the same "key-holes".
  • the keyhole does not require any physical depth, permitting the use of surface-mounted devices requiring no mounting boxes embedded in the wall.
  • the keys can be coded either during production or in connection with installation in the field, and the coding can be renewed when necessary. In the panels on the landing walls and elevator cars, only one key interface is needed, thus reducing the need for physical equipment.
  • the key tells the operational mode itself, thus eliminating the need for configuration work on the signal devices and car panels with regard to the key switches.
  • the use of key switches can also be easily extended to cover e.g. landing calls and equivalent.
  • the code key can also be applied in time/access control, in which case it is possible to record the time of usage of each key.
  • the code data of the key can be changed. This can also be done from the user interface of the elevator controller. If a key is lost, the right to use it can be eliminated separately for each key. In this way, the rest of the code keys associated with the system remain valid without safety risks.
  • the elevator controller 1 gives control signals to the elevator drive system (not shown), which comprises a motor which moves the elevator car and counterweight by means of a traction sheave and a hoisting rope.
  • the elevator controller 1 is connected by means of connecting cables to the shaft wiring 3, over which the data needed by the elevator system is transmitted in serial form.
  • Connected to the elevator controller 1 is also a specific user interface 2, by means of which the operation of the elevator can be controlled and tested e.g. during maintenance.
  • the shaft wiring 3 is connected to the control interfaces on each floor and in the car.
  • the figure shows one of these interfaces in the form of a call button box 4.
  • the box is located on a landing wall and is provided with push buttons 5 for up and down calls, the corresponding signals being transmitted by serial communication along the shaft wiring 3 to the elevator controller 1.
  • the surface-mounted box 4 Fitted in the surface-mounted box 4 are three short-circuit protected contact surfaces 6 connected to the serial communication bus.
  • the boxes on the other landings and in the elevator car are provided with corresponding contact surfaces.
  • the user interface 2 connected to the elevator controller 1 is also provided with contact surfaces like this.
  • the code key 7 is provided with elements 8 corresponding to the contact surfaces 6, onto which they can be fitted.
  • the code key has an electrically programmable memory in which the data corresponding to the operational modes of the elevator is stored.
  • the memory can be implemented using different memory elements, such as EEPROM or NVRAM circuits.
  • the communication between the key and the user interface can also be implemented using wireless techniques, as is well known from similar control devices. For example, by storing calls to certain floors in the key, the range of its application can be further extended.
