Definitions

  • the invention relates to a system for central administration, regional inspection and for the local monitoring of decentralized elevator systems, which in a modular structure at the administration level has an administration center with means and methods for electronic data processing, which has at least one with means and methods via a telecommunication connection at regional level to guarantee the maintenance of the plant is subordinate to the regional center to which at least one building with computer means for diagnosing plant activities of at least one plant is connected at a local level via a telecommunication connection.
  • Such facilities enable a rationalization of maintenance, a reduction in maintenance costs and an improved range of services in the area of elevator systems.
  • a device is known from US Pat. No. 3,973,648 which monitors elevator groups by means of a central computer via a modem connection.
  • An elevator group selected by the central computer sends data relating to operating, fault and alarm events in serial, digital form to the central computer.
  • a hardware interface with monitoring and transmission functions serves as the link between the elevator group and the central computer.
  • the disadvantage of the known device is that the data is passed on without being evaluated.
  • the central computer must evaluate the data received and decide whether a service call is indicated based on the evaluation.
  • the transmission of all current system data to the central computer requires a long occupancy of the leased lines and takes up a lot of computer time.
  • Another disadvantage of the known device is that the central computer calls the elevator groups to be monitored. As a result, the relevant system data is not recorded when it is created, but with a delay caused by the query cycle. In addition, at least at low traffic frequencies, there are inquiries for which there are no significant changes to the system data.
  • a device which comprises means for remote monitoring of elevator systems.
  • the data points of an elevator system to be monitored are connected to an auxiliary computer subordinate to a main computer.
  • an intelligent on-site main computer takes over the data from the auxiliary computers as well as the data from the elevator group control. These are processed by the main computer and forwarded to the central computer via a modem connection.
  • the central computer creates maintenance lists based on the data and transmits them to the responsible service center.
  • the disadvantage of the known device is that all data of an elevator group are processed and transmitted by means of a main computer. In the event of a malfunction or if the main computer needs maintenance (software maintenance etc.), remote monitoring of the entire elevator group fails.
  • Another disadvantage of the known device is that a modem connection to the central computer is required for each main computer. In buildings with several elevator groups, several postal lines up to the main computers located in the machine room must therefore be installed and rented.
  • a device is known from US Pat. No. 4,568,909 which comprises means for local and central remote monitoring of elevator systems.
  • One main computer per building records the data points of several using auxiliary units Elevator systems.
  • the main computer evaluates the data and decides whether there are new operating, fault and alarm events. It transmits them to a local service center via a modem connection.
  • Several service points are connected to a higher-level central computer.
  • the disadvantage of the known device is that the computer intelligence for an entire building is concentrated in a main computer. Only the connection of auxiliary units with the main computer result in a functioning monitoring system. Such a monitoring system proves to be less flexible in terms of configuration, hardware and software in terms of structure as complicated and costly as complex.
  • the invention aims to provide a device for the remote management of elevator systems. With the facility mentioned, new services for the customer are realized with the aim of simplifying the maintenance of elevator systems by means of central administration, planning and rationalization.

  • the system for remote administration of elevator systems shown in FIG. 1 can be divided hierarchically and functionally into four levels: administration level, regional level, building level and process level.
  • the modular structure of the system allows the individual levels to be largely independent. Each subordinate level can also function without its superordinate level. Without the administrative center 1, the system still works as a remote inspection system. Without regional center 3, the trunk system remains fully functional as an inspection system for the processes connected across the building. Without building control center 6, each individual process 11 can be monitored by means of peripherals 10 and maintenance case 15.

  • the operator of a regional center 3 has the possibility of making direct contact with persons involved in a process 11 on a speech channel which is separated in frequency from the data channel.
  • the operator of a house control center or the on-site service technician can claim verbal support in solving system problems from the regional control center 3.
  • Sending and receiving means are on the elevator side installed directly in the cabin. This enables people in need to report their predicament directly to the building or regional headquarters.
  • the regional center 3 allows an insight into all of its subordinate processes 11. By sending a telegram with control and address data of the peripherals 10 to be selected, the regional center 3 receives direct access to the process data, if required. Normally, however, as mentioned below, the data exchange will take place in the opposite direction.
  • the regional center 3 calls a communication module 7 only if a certain time has passed without contact. Function tests can be carried out in individual processes 11 from the regional center 3, and actions to remedy the fault condition can be initiated in the event of a fault. For these reasons, the modem 2 provided must be both self-selecting and self-answering. In addition, it must meet the requirements of telearm 5. With an additional circuit placed in the regional center 3 and not mentioned in the figures, voice connections can be established in a comparable manner with the above-mentioned data channels to the central building 6 or the individual peripherals 10.
  • the dialing unit 7.5 separates the data traffic from voice traffic into incoming and outgoing Direction.
  • the dialing unit 7.5 divides the telephone network-side information channel into the speech channel 12 and the data channel 13.
  • the modem 2 converts the data into a transferable two-frequency signal by means of frequency shift keying. In the incoming direction, it converts the frequency-modulated signals back into computer-compatible one-zero signals.

  • the communication computer 7.1 takes over the data from the connected processes 11 via the bus module 8 / building bus 9 explained below and stores them in the data buffer 7.2. It is not just a question of data. Every time you contact us With the peripheral modules 10, these are checked by the communication computer 7.1 for malfunctions.
  • Messages about disturbed peripheral modules 10 are also stored in the data buffer 7.2 and periodically forwarded to the regional center 3 together with the collected process data.
  • the communication module 7 does not decide whether process data is relevant for transmission or not. It merely takes over the above-mentioned data traffic between the on-site periphery 10 and the regional center 3. Process messages are processed exclusively by the peripheral modules 10 into process data relevant to transmission and forwarded to the communication module 7.
  • the processes 11 of a building can be inspected from the building control center 6.

  • the device shown in FIGS. 4 and 6 has a network bus 14 as a variant of the building bus 9.
  • a separately routed two-wire cable serves as the building bus 9 instead of the intrinsically-free network bus 14.
  • the network bus 14 is a serial bus using the high-voltage electrical installation available throughout the building. It does not require its own line network and enables signals to be fed in or received at any point in the power network that is accessible via sockets. For reasons of telecommunications authority, this means of transmitting information regarding range, transmission power and channel frequencies is restricted depending on the postal regulations.
  • the range is normally limited to your own property, the transmission power is in the range of a few milliwatts and the permissible frequency band has to be below the long-wave band.
