Abstract

The method for operating of a lift system entails recording at least one operating parameter (1.2) to determine a nominal output (1.1) through simulation of the operation of the lift system and/or through calculation. The lift system is operated by the operating parameter, and at least one actual output (4.1) produced by the lift system is measured and then compared with the nominal output. The operating parameter and nominal output are recorded in a log (2.1) in the form of an electronic file and/or hard copy, and a guaranteed value of the nominal output of the lift system is determined. Independent claims are also included for the following: (a) a log for the operating of a lift system; and (b) a guaranteed value for the nominal output of the operation of a lift system.

  • the number of stops during the journey from start to finish,
• Statistically derived values (e.g. mean values) of the above-mentioned quantities.

A set of such performance characteristics forms the target performance of the Elevator system, which typically takes several months before the system is built with a Customers agreed and negotiated in a technical and commercial sense becomes.

The disadvantage is that the customer is often promised a target service, the Compliance in the built elevator system is difficult to check.

The object of the invention is to provide a method for operating an elevator installation to improve that the predetermined and specified before the construction of the elevator system Target performance in a clearly defined form after the elevator system has been built becomes verifiable.

This object is achieved with a method for operating an elevator system the features of claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

When tendering an elevator system, the operation is simulated Elevator system or by another calculation method the corresponding Performance characteristics determined, for example, technically for the Dimensioning of the system and marketing side in the consulting or Sales argument can be used. Several commercially available software programs for the simulation or otherwise calculated images of the operation of Elevator systems are known.

In the method according to the invention for operating an elevator system, at least one operating parameter to achieve a target performance Simulation of the operation of the elevator system and / or determined by a calculation and recorded with this target performance. This is optionally done in a protocol.

The protocol is in the form of an electronic file and / or a document generated output of the simulation or calculation of the operation of the elevator systems, the the defined, calculated and / or simulated operating parameters and the summarizes predetermined target power of the elevator systems.

After its construction, the elevator system is equipped with the previously simulated operating parameters or passenger traffic operated and the Actual power generated by the elevator system is measured and with the predetermined Target performance compared. This makes it possible to clearly identify and check whether The target output and the actual output really match whether the elevator system has the Requirements of the construction project effectively met, whether the simulations and / or Calculations can correctly predict the operation of the elevator system.

The target performance consists of performance characteristics, here also guaranteed Called value, which is collected and preferably in an electronic file and / or in a document, e.g. B. in a guarantee certificate.

Dissatisfaction and disputes on the part of customers will definitely be avoided because it becomes clear whether the contractual provisions have been complied with have been or not.

In a preferred embodiment, the simulation or calculation of the Operating on a computer system performed with a computer program that is loaded into a memory of the computer system, with a processor of the computer system, who executes the computer program, the target power over a Simulation and / or calculation rule with the operating parameters and the Passenger traffic is linked. As a result, the simulation and / or Delivered results faster and with greater accuracy and calculation Reproducibility provided.

In a further preferred embodiment, the protocol comprises one Counterfeit protection, to prevent the operating parameters, the specifications, the Passenger traffic and / or the target performance can be changed unnoticed. In a In another preferred embodiment, the log contains an expiry date, which ensures that claims derived from the protocol can only be used during a limited period of time. In another preferred Embodiments are parts of the operating parameters such as the passenger traffic or the protocol is not or only partially disclosed; in this way it becomes e.g. allows details of the control of the elevator system to remain secret or for unimportant information to customers does not have to be presented in full.

An embodiment of the invention is explained below with reference to the accompanying drawings. It shows:

Fig. 1

Fig. 2

1 shows the sequence of the method steps for the operation of the elevator installation according to the invention.

In process step 1, the necessary specifications of the elevator installation initially recorded and a passenger traffic determined. This can be simulation or another calculation method can be used. The operating parameters 1.2 to Achieve a target performance 1.1 by simulating the operation of the Elevator system can be determined. The determination is preferably made by iterative Steps. Start operating parameters and specifications of the elevator system fixed and the corresponding performance of the elevator system is simulated calculated. If this power corresponds to the target power of the elevator system, the operating parameters 1.2 for achieving a target output 1.1 have already been found Service. Otherwise, other startup operating parameters and specifications of the Elevator system is fixed and the corresponding performance of the elevator system again calculated by simulations. This trial and error procedure continues until the requirements of the target performance are met.

In a preferred embodiment, the simulation and / or Calculation of the operation of an elevator system according to the specifications and the Passenger traffic carried out on a computer system, using a computer program, which is loaded into a memory of the computer system, with a Processor of the computer system that executes the computer program, the simulated or calculated performance characteristics via a simulation and / or Calculation rule with the operating parameters, the specifications and the Passenger traffic can be linked. For example, there is an iterative change of at least one operating parameter in order to achieve a desired target power with the Reach computer program. An optimization is preferably carried out in which a variety of options only one or a few preferred ones, e.g. according to predetermined target criteria, the best possible changed operating parameters become. This optimization is repeated until the operating parameters meet the requirement meet the target performance.

If, for example, the simulations show that three lifts per group are not A further simulation will be sufficient if the desired number of passengers is served with four lifts per group. If this simulation reveals that four elevators per group not the desired number of passengers a further simulation with a different type of Elevator control carried out, for example with a destination call control.

• garantierte Werte für die Leistungs-Charakteristika einer entsprechend den Spezifikationen erstellten Anlage bestimmt werden, z.B. indem die Spezifikationen oder die simulierten bzw. berechneten Werte der Leistungs-Charakteristika um einen bestimmten relativen und/oder absoluten Anteil (Faktor) abgeschwächt werden
• eine oder mehrere Dateien in Form eines Protokolls 2.1 erstellt werden, welche die Spezifikationen, den Passagier-Verkehr, die abgeleiteten Leistungs-Charakteristika sowie die garantierten Werte umfassen.

In method step 2, when a corresponding function is called up, a guarantee certificate is created, based on the specifications, the passenger traffic and the simulated or calculated performance:

• guaranteed values for the performance characteristics of a system created in accordance with the specifications are determined, for example by weakening the specifications or the simulated or calculated values of the performance characteristics by a certain relative and / or absolute proportion (factor)
• one or more files are created in the form of a protocol 2.1, which include the specifications, the passenger traffic, the derived performance characteristics and the guaranteed values.

The protocol 2.1 can consist of several sets of operating parameters 2.2, i.e. Specifications, passenger traffic, derived performance characteristics as well guaranteed values exist, as explained in FIG. 2.

The guarantee certificate is given to the customer. An expiry date can be found on the Allow warranty certificate derived claims only for a limited time.

If the elevator system is implemented according to the specifications, the Customers can be verified with the guarantee certificate.

In step 3, protocol 2.1 becomes a set of operating parameters 3.1 selected, which is characterized by a predetermined passenger traffic.

The elevator installation is then in step 3 with the operating parameters 3.1 in operated a reference company. Passenger traffic is an operating parameter previously known. All passenger calls recorded in the corresponding passenger traffic are not from the keyboard in the cabin or on the floor, but from the Protocol entered directly into the controller.

In method step 4, the actual power 4.1 of the elevator installation is measured.

The passenger calls and movements of cabins and doors are all in one Measurement log recorded. The movements of cabins and doors can at the same time observed by the customer and logged independently. The The measurement protocol is then evaluated, preferably using a protocol analyzer.

The protocol analyzer is one of the most in the form of a computer program circumscribed fixed procedure, the measurement protocol and the Guarantee certificate reads, checks, compares and finally provides the information, whether the actual performance matches the target performance.

Typically, the protocol analyzer reads those contained in the measurement protocol Data and operating parameters in the form of a list in a text file or in a Excel table is available and that during the reference operation of the elevator system have been measured effectively. The protocol analyzer first checks the Consistency of this data and controls whether the operational and physical Conditions for the operation of the elevator system have been effectively observed. He then calculates the performance characteristics of the Elevator system (waiting times, target times, etc.). The log analyzer also reads the Data and operating parameters contained in the guarantee certificate, which correspond to the target performance correspond to the elevator system and compare these values with those from the Measurement protocol derived values. Finally, it provides a summary of the results and confirms whether the actual performance of the elevator system meets the target performance specified conditions met.

The actual power 4.1 of the elevator system is in step 5 with the target power 1.1 compared or the measured performance characteristics and the Measured values are included in the guarantee declarations contained in the guarantee certificate compared.

The result of comparison 5.1 enables definitive, verifiable, safe and Clear statement to formulate whether the elevator system is in the target performance provided specifications and requirements are met.

The passenger traffic is preferably set so that high performance of the Elevator system can be shown, but not too high, so deviations between simulation and implemented system not too strong effects on the Have values of performance characteristics. This could be done through an appropriate Simulation and / or calculation methods are supported, which are based on the Specifications generates a corresponding meaningful passenger traffic.

• minimaler Anzahl bedienter Personen pro 5 Minuten,
• maximaler durchschnittlicher Zielzeit,
• maximaler durchschnittlicher Wartezeit

oder anderer messbarer oder berechenbarer Grössen und davon statistisch abgeleiteter Werte.The guarantee declarations are based on the values determined by means of simulation and / or calculation, for example regarding:

• minimum number of people served per 5 minutes,
• maximum average target time,
• maximum average waiting time

or other measurable or calculable quantities and statistically derived values.

Because of the risk, the simulated values are not in the implemented system to be able to adhere to admit a security area (risk surcharge). This Security area should not be too large to choose the value of the guarantee certificate not to lower too much. The values determined by means of simulation are considered the best Estimate given and somewhat weakened values are guaranteed.

The degree of attenuation and the breadth of the security range of the values of the The best estimate depends on the size under consideration and is based on Empirical values or statistical considerations and / or methods determined, which the possible differences between target and actual performance or their Consider causes in simulations or other calculation methods. For example, possible disturbances, e.g. slower cabin or Door movements as provided in the operating parameters, simulated or their Effects on performance characteristics are calculated. Performance characteristics, which vary more statistically are weakened more. This can also be very different depending on the operating parameters, e.g. depending on the elevator control.

The guarantee certificate comes in a preferred version with a counterfeit protection which ensures that it cannot be changed unnoticed. The protocol is therefore clearly open using a publicly accessible procedure its authenticity can be checked. This counterfeit protection is, for example, one of one or several electronic documents calculated string, which in one written document is recorded. The procedure for calculating the String preferably the property that it is well known and that it is very difficult or impossible to use the same string with different ones Achieve source documents. A known such method is, for example the MD5 algorithm (RFC 1321).

The guarantee certificate is at least partially encrypted so that the customer does not knows or needs to know all information about the behavior of the elevator system. This is interesting for the elevator company because details of the Operating parameters can affect trade secrets. The disclosed Information is chosen so that the verifiability of the guaranteed performance is sufficiently guaranteed.

A preferred solution to the problem is as follows.

The guarantee certificate consists of an electronic file and one written document, both of which have counterfeit protection, which also confirmed their togetherness.

The electronic file includes the specifications, the guarantee declarations as well the passenger traffic as a list of elevator calls per time and type, for example "Destination call at start stop x with destination stop y at time T" in a destination call controller. The Allocations of calls to cabins and the cabin / door movements are in the File not saved.

The written document is the same as the electronic file, but only one Part of the passenger traffic, for example randomly selected 15% of all elevator calls.

For the verification, the passenger traffic, i.e. the elevator calls, entered into the control of the elevator system. The behavior of the System is recorded in a measurement protocol, which also includes the allocation of Calling to cabins and describing the movements of cabins and doors.

The written documents are e.g. as part of the purchase contract in duplicate signed and exchanged between the elevator company and the customer. Depending on The design of counterfeit protection and / or encryption will Guarantee certificate with a computer program for its authenticity or Checked for integrity. Under certain circumstances, such Verification program or parts thereof can be left to the customer so that this itself can determine the authenticity or integrity at any time without the customer it can reveal the encrypted parts.

The measurement protocol may not be fully accessible to the customer. This receives the list of all cabin and door movements as well as the Cabin assignments of those calls that correspond to the part of the document published in the document Correspond to passenger traffic. The customer himself has the option of Observe movements of cabins and doors.

The elevator company uses the measurement protocol to determine the warranty statements described performance characteristics for all passenger traffic as well as for the part of it published in the document. The latter can Customer himself verify what, for example, by the elevator company with appropriate Tools, for example an Excel program, can be supported.

The review agreement can, for example, provide that both the Performance characteristics with regard to total traffic such as partial traffic within the guarantee declarations must lie. In this case, the guarantee declarations will be like this chosen that a corresponding partial traffic has the highest probability, to fulfill these.

The process steps described are exemplary and are intended to be similar or a more general implementation of the described subject cannot be excluded.
