Description

The invention relates to a method for communication with eggs elevator system according to the preamble of patent claim 1.

The font EP1415947A1 describes a device and a method for the remote maintenance of an elevator installation, which device is installed on the elevator installation and receives first signals from an elevator control and / or from a sensor. The device evaluates received first signals according to an activated remote maintenance function and forwards the result of this evaluation as second signals via a telecommunication network to a remote maintenance center.

The present invention has as its object to further develop this device and this method.

This object is achieved by the invention according to the characterizing part of patent claim 1.

The invention relates to a method for communication between at least one elevator installation and at least one remote control center; wherein for this communication at least one communicative connection is established in at least one communication network; wherein at least a first signal of the elevator installation is received by at least one communication device of the elevator system via at least one signal network, and at least one second signal is transmitted from the communication device in the communication network to at least one computer device of the remote center. The communicative connection is permanently maintained.

This has the advantage that communication is not required to establish a connection, which increases the quality and availability of the communication. Whereas a subscriber dials in at a Plain Old Telephone Service (POTS) and requires about 30 seconds to set up an exclusive temporary connection, the inventive communicative connection is permanently maintained and highly available in fractions of a second. Especially in emergencies, where help is requested from the elevator installation at the remote control center and emergency measures are initiated at the elevator installation from the remote control center, the time saved with the highly available communicative connection is of safety-relevant importance in an emergency.

Advantageous developments of the invention will become apparent from the features indicated in the dependent claims.

Advantageously, the communicative connection is established by the communication device.

This has the advantage that the communication device establishes the communicative connection and therefore does not require a fixed address in the communication network, which is also of security relevance, since the communication device is thus known to third parties in the communication network. The address of the communication device in the communication network is known only to the remote center, which is an effective preventative measure against attacks by viruses or Trojans.

Advantageously, at least one signaling channel of the established communicative connection is transmitted continuously in at least one physical channel.

This has the advantage that the communicative connection is maintained by continuously transmitting in a signaling channel. In the telephone radio network according to Global System for Mobile Communications (GSM), for example, communication takes place in Time Division Multiplex Access (TDMA) time slots of 577μsec duration. The signaling channel always sends at maximum power so that the communication device, depending on the currently available bandwidth of the communication network, can select the most to be received signaling channel for a secure communication link.

Advantageously, the communicative connection is established by the communication device; During the communicative connection, a second signal is transmitted by the communication device, and signal reception is prevented by at least one firewall of the communication device.

This has the advantage that the communication device establishes the communicative connection and a firewall of the communication device only allows the transmission of a second signal from the communication device, but no signal reception by the communication device, which in turn forms a security-relevant measure against attacks by viruses or Trojans.

Advantageously, a virtual private network (VPN) is used as the communication network as a communication link.

This has the advantage that the communication device and the remote center are in a private, i. individually configurable communication network takes place. Only the communication device knows the private address of the remote center in the communication network and only the remote center knows the private address of the communication device in the communication network.

Advantageously, a virtual private network (VPN) with tunnel technology is used as the communication network as the communication network. Advantageously, a second signal is transmitted encrypted by the communication device. This has the advantage that the communication network is based on tunneling technology, in which the second signal to be communicated is embedded in a communication protocol, which is enclosed by a shell that obscures the actual content for third parties. The second signal to be communicated is thus encrypted before the communication, for example as a secure sockets layer (SSL) and decrypted accordingly after successful communication.

Advantageously, a wireless wide area network (WWAN) without Internet access is used as the communicative connection.

This has the advantage that no public and thus in principle unsecured communication network such as the Internet is used. The communicative connection thus takes place under exclusion of the public, which further increases the security of the communication.

Advantageously, a LAN with Internet access is used as the communicative connection.

This has the advantage that a cost-effective communicative connection takes place in a public communication network. In order to ensure sufficient security against third parties, an encrypted communicative connection takes place. In addition, at the communication device and the remote central firewalls are installed, which determine firewalls based on at least one predefined rule, whether a signal reception is prevented or not.

Advantageously, a telephone radio network is used as the communication network. Advantageously, a radio network is used as the communication network.

This has the advantage that the communication network is a well-known and proven telephone radio network such as GSM, General Radio Packet Services (GPRS), Enhanced Data Rate for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), High Speed Download Packet Access (HSDPA), etc. is used, which ensures high availability and thus security of the communicative connection.

Advantageously, a telephone landline is used as the communication network. Advantageously, a network is used as the communication network.

This has the advantage that a known and proven telephone landline network such as Integrated Services Digital Network (ISDN), Asymetric Digital Subscriber Line (ADSL), Very High Data Rate Digital Subscriber Line (VDSL), etc., is used as the communication network, which guarantees a high availability and thus security of the communicative connection.

Advantageously, at least one voice signal is transmitted as the first signal from at least one elevator car telephone in the signal network to the communication device; and at least one data signal is transmitted as the first signal from the elevator car telephone in the signal network to the communication device.

This has the advantage that both a voice signal and a data signal of an elevator car telephone in the signal network are transmitted to the communication device.

Advantageously, the transmitted data signal is converted by the communication device into at least a second signal; and the second signal is transmitted by the communication device via the communicative link at a transmission rate of at least 4.8kBit / sec.

This has the advantage that the data signal is converted into a second signal for the purposes of the communication, which second signal can be reliably and reliably communicated at a transmission rate of at least 4.8 kbit / sec. Just in a GSM communication network, when the communication network is saturated, the transmission rate may drop drastically, degrading the transmission quality of the second signal. If, in an emergency, a second signal of the communication device can not be reliably read by the remote center due to poor transmission quality, this is of safety significance. Here, a transmission rate of at least 4.8 kbit / sec ensures that the communicative connection is sufficiently robust for reliable reading of a transmitted second signal.

Advantageously, the transmitted data signal is converted by the communication device into at least one Cellular Text Modem (CTM) signal as a second signal.

This has the advantage that the data signal is converted into a CTM signal as a second signal for the purpose of the communication, which CTM signal can be communicated safely and reliably.

Advantageously, at least one dual-tone multi-frequency (DTMF) signal is transmitted as the first signal from at least one elevator car telephone in the signal network to the communication device; and the transmitted DTMF signal is converted by the communication device into at least one CTM signal as a second signal.

This has the advantage that a known from analog telephone technology DTMF signal is converted for the purposes of communication in second signals, which are safe and reliable communication. The DTMF signal is a multi-frequency signal with dissonances, which can be distorted when the bandwidth of the communication network is saturated and thus can no longer be clearly identified with high reliability.

Advantageously, the CTM signal is sent from the communication device to the remote via the communicative link

Central transmitted. Advantageously, the transmitted CTM signal is converted by the remote center into at least one data signal. Advantageously, the transmitted CTM signal is converted by the remote center into at least one DTMF signal.

This has the advantage that the remote center converts a transmitted CTM signal into a DTMF signal. Especially in an emergency, where a communicated by the communication device data signal must be read reliably from the remote control center, this is of security importance.

Advantageously, at least one sensor transmits at least one sensor signal as the first signal in the signal network to the communication device. Advantageously, the sensor signal indicates at least one status information of the elevator installation, such as an indication of at least one operational readiness and / or at least one error log and / or at least one load per unit time. Advantageously, at least one elevator control of the elevator installation transmits at least one data signal as the first signal in the signal network to the communication apparatus. Advantageously, at least one escalator control of the elevator installation transmits at least one data signal as the first signal in the signal network to the communication apparatus. Advantageously, at least one call signal of the elevator installation transmits at least one data signal as the first signal in the signal network to the communication apparatus. Advantageously, at least one status information of the elevator control and / or escalator control and / or call control, such as an indication of at least one readiness for operation and / or at least one error log and / or at least one load per unit time, is indicated with the data signal.

This has the advantage of not only an elevator car telephone, but also of a sensor, of an elevator control and a call control transmits a first signal to the communication device.

Advantageously, a first signal is converted by the communication device into a second signal; the second signal is transmitted from the communication device in the communication network to the remote center computer; a transmitted second signal is converted by the computer device into a first signal; and from the computer device, the converted first signal is evaluated.

This has the advantage that the communication device converts the first signal into a second signal and transmits the second signal safely and reliably to the remote center.

• Das Kommunikations-Netz 14 kann ein Telefon-Funknetz 14 wie Global Systems for Mobile Communications (GSM), General Radio Packet Services (GPRS), Enhanced Data Rate for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), High Speed Download Packet Access (HSDPA), usw. sein. Die vom Telefon-Funknetz 14 verwendeten Frequenzen liegen bei GSM und GPRS in Bändern bei 800 bis 900MHz und 1800MHz bis 1900MHz, sowie bei UMTS und HSDPA bei 700 bis 900MHz und 1700MHz bis 2700MHz. Eine kommunikative Verbindung des Telefon-Funknetzes 14 erfolgt über mindestens einen logischen Kanal bestehend aus mindestens einem Signalisierungskanal und einem Nutzkanal. Der Signalisierungskanal dient der Übermittlung von netzwerkspezifischen Parametern, Frequenzkorrekturen, zeitlichen Aufsynchronisierung, usw. der kommunikativen Verbindung. Der Signalisierungskanal kann auch Sprache und/oder Daten übermitteln. Der Nutzkanal dient der ausschliesslichen Übermittlung von Sprache und/oder Daten. Der logische Kanal wird auf mindestens einen physikalischen Kanal abgebildet. Ein physikalischer Kanal wird durch Zeit- und Frequenzmultiplexing oder Time Division Multiplex Access (TDMA) gebildet. Somit erfolgt eine Kommunikation im Telefon-Funknetz 14 in TDMA-Zeitschlitzen von 577µsec Dauer. Acht aufeinanderfolgende TDMA-Zeitschlitze bilden einen TDMA-Rahmen. Dieselben TDMA-Zeitschlitze in aufeinanderfolgenden TDMA-Rahmen bilden einen physikalischen Kanal. Aufbau und Aufrechterhaltung einer kommunikativen Verbindung im Telefon-Funknetz 14 ist also durch Belegung mindestens eines TDMA-Zeitschlitzes pro TDMA-Rahmen gekennzeichnet. Dabei sendet der Signalisierungskanal kontinuierlich im zugeteilten physikalischen Kanal, während der Nutzkanal bei Sprachpausen oder Datenpausen in einem diskontinuierlichen Betrieb (Discontinuous Transmission oder DTX) das Senden unterbrechen kann. Die Übermittlung über den Nutzkanal kann sowohl leitungsvermittelt als auch paketvermittelt sein. Der Nutzkanal kann unterschiedliche Übertragungsraten von 13kBit/sec, 6.5kBit/sec, usw. aufweisen. Bei GSM beträgt die maximale als auch die effektiv nutzbare Übertragungsrate 9.6kBit/sec. Bei GPRS beträgt die maximale Übertragungsrate 80kBit/sec, effektiv nutzbar sind oft jedoch nur 50kBit/sec, da die Übertragungskapazität auf alle Teilnehmer einer Funkzelle aufgeteilt wird. Bei EDGE beträgt die maximale Übertragungsrate 256kBit/sec, aufgrund der Aufteilung der Übertragungskapazität auf alle Teilnehmer einer Funkzelle sind aber effektiv nur 150kBit/sec nutzbar. Aus den gleichen Gründen beträgt bei UMTS beträgt die maximale Übertragungsrate 384kBit/sec, wovon aber effektiv nur 128kBit/sec nutzbar sind. Bei HSDPA schliesslich beträgt die maximale Übertragungsrate 3.6MBit/sec, wovon effektiv nur 1MBit/sec nutzbar sind. Für eine effiziente Ausnutzung des Nutzkanals wird Sprache vor der Übermittlung beim Sender von einem Sprachkompressor komprimiert und nach der Übermittlung beim Empfänger von einem Sprachexpander expandiert.
• Das Kommunikations-Netz 14' kann ein Telefon-Festnetz 14' wie Public Switched Telecommunication Network (PSTN) sein. Das Telefon-Festnetz 14' kann analog und/oder digital ausgestaltet sein. Bei einem analogen Telefon-Festnetz 14' werden analoge Tonsignale übermittelt. Die Bandbreite ist dabei auf den Frequenzbereich von 300Hz bis 3400Hz begrenzt. Neben einem Sprachsignal werden weitere Signale wie ein Wählsignal, ein Rufsignal, usw. übermittelt. Ein digitales Telefon-Festnetz 14' ist als Integrated Services Digital Network (ISDN), Asymetric Digital Subscriber Line (ADSL), Very High Data Rate Digital Subscriber Line (VDSL), usw. bekannt. Beim ISDN stehen zwei Nutzkanäle mit je 64kBit/sec Übertragungsrate und eine Teilnehmerschnittstelle S₀ mit 16kBit/sec Übertragungsrate zur Verfügung. Beim ADSL wird ein wesentlich grösserer Frequenzbereich von 200Hz bis 1.1MHz ausgenutzt, wobei die Bandbreite bis 3400Hz für die Übermittlung von Sprachsignalen verwendet wird, während die Bandbreite von 30kHz bis 1.1MHz für die Übermittlung von Datensignalen verwendet wird. Die Übertragungsrate zum Endgerät beträgt bei ADSL bis zu 8MBit/sec während sie bei VDSL über 200MBit/sec betragen kann.
• Das Kommunikations-Netz 14" kann ein Netzwerk 14" wie Ethernet, ARCNET, usw. mit mindestens einer elektrischen- bzw. optischen Signalleitung sein. Gemäss Fig. 2 und 3 sind ein Netzwerkanschluss 13.12 der Kommunikationsvorrichtung 13 und ein Netzwerkanschluss 15.12 der Rechnereinrichtung 15 über ein Netzwerk 14" miteinander verbunden. Das Netzwerk 14" erlaubt eine bidirektionale Kommunikation gemäss bekannten und bewährten Netzwerk-Protokollen wie das Transmission Control Protocol / Internet-Protocol (TCP/IP), Internet Packet Exchange (IPX), usw..

At least one communication network 14 to 14 " enables a transmission of signals between the communication device 13 of the elevator installation A and at least one computer device 15 of at least one remote center Z. Exemplary embodiments of the communication network 14 to 14" are explained below:

• The communication network 14 may include a telephone radio network 14 such as Global Systems for Mobile Communications (GSM), General Radio Packet Services (GPRS), Enhanced Data Rate for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), High Speed Download Packet Access (HSDPA), etc. The frequencies used by the telephone network 14 are in GSM and GPRS in bands at 800 to 900MHz and 1800MHz to 1900MHz, and in UMTS and HSDPA at 700 to 900MHz and 1700MHz to 2700MHz. A communicative connection of the telephone radio network 14 occurs via at least one logical channel consisting of at least one signaling channel and a traffic channel. The signaling channel is used to transmit network-specific parameters, frequency corrections, time synchronization, etc. of the communicative connection. The signaling channel can also transmit voice and / or data. The traffic channel is used exclusively for the transmission of voice and / or data. The logical channel is mapped to at least one physical channel. A physical channel is formed by Time and Frequency Division Multiplexing or Time Division Multiplex Access (TDMA). Thus, a communication takes place in the telephone radio network 14 in TDMA time slots of 577μsec duration. Eight consecutive TDMA time slots form a TDMA frame. The same TDMA time slots in consecutive TDMA frames form a physical channel. Establishment and maintenance of a communicative connection in the telephone radio network 14 is thus characterized by occupying at least one TDMA time slot per TDMA frame. In this case, the signaling channel transmits continuously in the allocated physical channel, while the user channel can interrupt the transmission in the case of speech pauses or data pauses in discontinuous operation (discontinuous transmission or DTX). The transmission over the traffic channel can be both circuit-switched and packet-switched. The traffic channel can have different transmission rates of 13kBit / sec, 6.5kBit / sec, and so on. With GSM the maximum as well as the effectively usable transfer rate is 9.6kBit / sec. With GPRS, the maximum transmission rate is 80kBit / sec, but often only 50kBit / sec can be used effectively, as the transmission capacity is shared among all nodes of a radio cell. With EDGE, the maximum transmission rate is 256kBit / sec, but due to the distribution of the transmission capacity to all subscribers of a radio cell, only 150kBit / sec can effectively be used. For the same reasons, the maximum transmission rate for UMTS is 384kBit / sec, but effectively only 128kBit / sec can be used. Finally, with HSDPA, the maximum transmission rate is 3.6MBit / sec, of which effectively only 1MBit / sec can be used. For efficient utilization of the payload channel, voice is compressed by a voice compressor prior to transmission at the transmitter and expanded by a voice expander after being transmitted to the receiver.
• The communication network 14 'may be a telephone landline 14' such as Public Switched Telecommunication Network (PSTN). The telephone landline 14 'may be configured analog and / or digital. In an analog telephone landline 14 'analog audio signals are transmitted. The bandwidth is limited to the frequency range of 300Hz to 3400Hz. In addition to a voice signal further signals such as a dial signal, a call signal, etc. are transmitted. A fixed telephone digital network 14 'is known as Integrated Services Digital Network (ISDN), Asymmetric Digital Subscriber Line (ADSL), Very High Data Rate Digital Subscriber Line (VDSL), etc. In ISDN, two user channels with 64kBit / sec transmission rate each and a subscriber interface S ₀ with 16kBit / sec transmission rate are available. The ADSL utilizes a much wider frequency range from 200Hz to 1.1MHz, with bandwidth up to 3400Hz being used to transmit voice signals, while the bandwidth from 30kHz to 1.1MHz is used to transmit data signals. The transmission rate to the terminal with ADSL is up to 8MBit / sec while at VDSL it can be over 200MBit / sec.
