Definitions

  • the invention relates to a device for inputting travel commands for an elevator, with storey call memories and storey call buttons, with car call stores and car call buttons, with a scanning device which scans the car and storey call stores for the purpose of determining stored calls, a first and a second signal sequence being generated, which contain the stored calls, and with a control device into which a car call or floor call can be transmitted only when the elevator car is at a standstill, and which direction and stop signals are generated for direct travel to selected floors.
  • CH-PS 622 226 discloses a device for the transmission of control signals in which a car or floor call can only be entered on a floor while the elevator car is stationary and can be transmitted to a control device.
  • the logic of the floor call buttons is interrupted by means of a logic circuit, so that their actuation remains ineffective.
  • the cabin and floor call buttons are connected in series to the power supply, so that the simultaneous entry of several calls is prevented.
  • No memories assigned to the floors are provided for storing the floor and car calls. When a call is entered, it is coded using a diode matrix and transferred to a memory in the control device.
  • the call is compared with the cabin position transmitted in coded form during the journey, and direction of travel and stop signals are generated for the purpose of direct travel to selected floors. Since, because of the series connection of the floor call buttons, only the call that is entered via a floor call button that is closest to the entry point can be transmitted, with this device the calls cannot be served in the order in which they were entered, so that for some people the Passengers waiting on floors can experience relatively long waiting times.
  • the floor calls entered are summarized in chronologically consecutive call groups, which are operated during consecutive operating stages.
  • the floor calls are stored in floor call memories, which are scanned by means of a scanning device, a signal sequence containing the stored floor calls being generated.
  • the scanning device controls a blocking and a releasing device in such a way that the floor calls that form a call group and are entered during a running operating stage are blocked and released for operation in the subsequent operating stage after the current operating stage has ended.
  • the floor calls of the released call group are processed in the order of the scanning. An operation of the floor calls corresponding exactly to the chronological order of the call inputs is therefore not possible with this device either.
  • the scanning device has a counter which, for the purpose of scanning the floor call memory, generates addresses assigned to the floors. If a floor call occurs in a second signal sequence generated during scanning, the associated address is entered in shift registers, an input circuit monitoring the assignment of the shift registers only releasing the input when the first shift register memories are empty. After the address stored in the last shift register memories has been transferred to the control device, an erase circuit deletes the last shift register memories and causes further addresses stored in the shift registers to be shifted on.
  • the advantages achieved by the invention are that, with a sufficiently high sampling frequency, at most one call per sampling cycle occurs in the second signal sequence generated by the scanning device, so that the floor calls can be transmitted to the control device in the chronological order of the input via the shift register and the waiting times of all passengers are reduced to a minimum.
  • 1, 1 denotes an elevator shaft in which an elevator car 2 is guided.
