Description

The invention relates to a method for operating a lift system having the characteristics of the general concept of claim 1.

The contracting authority shall inform the contracting authority of the relevant contracting authority of the relevant contracting authority of the relevant contracting authority. the number of stops operated,the distance from one stop to the next,the number of persons to be operated at a stop,the number of lifts in the elevator system concerned,the type of elevator control and passenger interfaces,a passenger transport,for example with a number of calls per floor and random target floor movements selected depending on the number of persons to be operated at a stop,and per elevator: □ the type of lift (e.g. maximum speed, information on curves, e.g. by means of acceleration and jerking, or travel times between stops or certain routes);□ the type of cabin (e.g. number of decks, size, maximum load weight, maximum number of persons);□ the type of cabin doors (e.g. width, opening, holding and closing times).

Such specifications define the operating parameters of the lift, including physical conditions and constraints that influence and determine the operation and performance of a lift.

The customer places high demands on an elevator system, and various performance characteristics of an elevator system can be measured in a given passenger traffic according to the current state of the art or determined by simulation or other calculation methods, such as: the number of passengers served in a given period of time,per passenger: □ the time taken by the passenger to reach his destination by means of the elevator from his starting position (destination time);□ the time between the call he makes or his arrival at the elevator and the arrival of the elevator cabin serving him (waiting time);□ the number of stops during the journey from starting position to the final destination;

A set of such performance characteristics constitutes the target performance of the lift system, which is typically agreed with a customer several months before the construction of the system and negotiated in a technical and commercial sense.

The disadvantage is that the customer is often promised a target performance, the fulfilment of which is difficult to verify in the elevator system built.

The purpose of the invention is to improve a procedure for the operation of a lift system in such a way that the target performance, predetermined and specified before the construction of the lift system, can be verified in a clearly defined form after the construction of the lift system.

This task is solved by a procedure for operating a lift system with the characteristics of claim 1.

The subclaim is directed to the invention.

In the tendering process, the relevant performance characteristics are determined by simulating the operation of the elevator or by another calculation method, which is used for example technically for the dimensioning of the installation and on the marketing side in the consulting or sales reasoning.

In the method of operation of a lift, at least one operating parameter to achieve a target performance is first determined by simulation of the operation of the lift and/or by calculation and recorded with that target performance, or optionally in a log.

The log shall be the output of the simulation or calculation of the operation of the lift, generated in the form of an electronic file and/or document, summarising the determined, calculated and/or simulated operating parameters and the preset target performance of the lift.

After the elevator has been constructed, it is operated according to the specifications with the previously simulated operating parameters or passenger traffic, and the actual power generated by the elevator is measured and compared with the specified target power, which allows to clearly identify and verify whether the target power and the actual power really match, whether the elevator effectively meets the requirements of the construction project, and whether the simulations and/or calculations can correctly predict the operation of the elevator.

The intended performance is therefore composed of performance characteristics, here also referred to as guaranteed value, which are collected and preferably recorded in an electronic file and/or document, e.g. a guarantee certificate.

In any case, customer dissatisfaction and disputes are avoided because it is clear whether the contractual provisions have been complied with or not.

In a preferred embodiment, the simulation or calculation of operations is performed on a computer system, with a computer program loaded into a computer system memory, with a computer system processor executing the computer program, linking the target performance to the operating parameters and passenger traffic via a simulation and/or calculation rule, providing faster, more accurate and reproducible results from the simulation and/or calculation.

In another preferred embodiment, the protocol includes a tamper-proofing feature to prevent unnoticed changes to the operating parameters, specifications, passenger traffic and/or target performance; in another preferred embodiment, the protocol includes an expiration date, which ensures that claims derived from the protocol are only asserted for a limited period of time; in another preferred embodiment, parts of the operating parameters, such as passenger traffic or the protocol, are not or only partially disclosed, which allows, for example, the details of the control of the lift or information that is not important to the customer to be disclosed in a comprehensive manner.

An example of the invention is explained in detail below by means of the accompanying drawing, which shows: Figure 1 a schematic representation of the procedure for operating the lift system.

Figure 1 shows the sequence of steps for operating the lift system according to the invention.

Err1:Expecting ',' delimiter: line 1 column 971 (char 970)

In preferred mode, step 1 of the procedure involves the simulation and/or calculation of the operation of an elevator according to the specifications and of passenger traffic on a computer system, with a computer program loaded into a memory of the computer system, with a computer system processor executing the computer program, linking the simulated or calculated performance characteristics via a simulation and/or calculation with the operating parameters, specifications and passenger traffic, for example by iteratively changing at least one operating parameter to achieve a desired performance with the computer program. Preference is given to optimizing the operation until a number of options are used or only a few options are used to optimize the operation, if the desired performance is achieved.

For example, if the simulations show that three lifts per group do not meet the desired number of passengers served, another simulation with four lifts per group shall be performed; if this simulation again shows that four lifts per group do not meet the desired number of passengers served, another simulation shall be performed with another type of lift control, for example with a destination call control.

In step 2 of the procedure, when a corresponding function is called, a guarantee certificate shall be established by: □ guaranteed values for the performance characteristics of a system produced in accordance with the specifications are determined, e.g. by attenuating the specifications or the simulated or calculated values of the performance characteristics by a certain relative and/or absolute proportion (factor);

The protocol 2.1 may consist of several sets of operating parameters 2.2, i.e. specifications, passenger traffic, derived performance characteristics and guaranteed values, as shown in Figure 2.

The guarantee certificate is issued to the customer. e expiry date may only allow claims derived from the guarantee certificate for a limited period.

If the lift is built according to the specifications, the customer with the guarantee certificate can be verified.

In step 3 of the procedure, a set of operating parameters 3.1 is selected from Protocol 2.1 and characterised by a predefined passenger traffic.

The lift is then operated in a reference operation in step 3 with the operating parameters 3.1 and passenger traffic is the operational parameter. All passenger calls recorded in the corresponding passenger traffic are not entered directly into the controller via the keyboard in the cabin or floor, but from the log.

In step 4 of the procedure, the actual power 4.1 of the lifting system is measured.

The passenger calls and movements of cabins and doors are recorded in a measurement log, which can be monitored by the customer and independently recorded, and the measurement log is then evaluated, preferably by a log analyzer.

The protocol analyzer is a fixed procedure, most often described in the form of a computer program, which reads the measurement protocol and the guarantee certificate, checks, compares and finally provides information on whether the actual performance matches the intended performance.

Typically, the log analyzer reads the data and operating parameters contained in the measurement log, which are listed in a text file or Excel table and which have been effectively measured during the reference operation of the lift. The log analyzer first checks the consistency of these data and checks whether the operational and physical conditions for the operation of the lift have been effectively met. It then calculates from the measurement log the performance characteristics of the lift (standby times, target times, etc.). The log analyzer also reads the data and operating parameters contained in the guarantee certificate that correspond to the performance of the lift and compares these with the measurement logs.

The actual power 4.1 of the lifting system is compared with the target power 1.1 in procedure step 5 or the measured performance characteristics and measured values are compared with the warranty statements contained in the guarantee certificate.

The result of the comparison 5.1 shall allow a definitive, verifiable, reliable and unambiguous statement to be made as to whether the lifting system meets the specifications and requirements set out in the target performance.

Passenger traffic shall preferably be defined in such a way that high performance of the lifting system can be demonstrated, but not too high, so that deviations between simulation and realised system do not have too strong an impact on the performance characteristics values.

The guarantee statements shall be based on values obtained by simulation and/or calculation, for example concerning: minimum number of persons per 5 minutes,maximum average target time,maximum average waiting time or other measurable or predictable quantities and statistically derived values.

The risk of failure to comply with the simulated values in the plant being built requires the allocation of a safety margin (risk premium), which must not be too large to reduce the value of the guarantee certificate too much.

The degree of attenuation and the safety range of the best estimate values are dependent on the size under consideration and are determined on the basis of empirical values or statistical considerations and/or methods which take into account the possible differences between intended and actual performance or their causes in simulations or other calculation methods. For example, possible disturbances, e.g. slower cabin or door movements than foreseen in the operating parameters, can be simulated or their impact on performance characteristics calculated.Performance characteristics which vary more statistically are more weighted. This may also vary greatly depending on the operating parameters, e.g. the lifting rate.

The certificate of guarantee is given a preferable listing with a counterfeit protection, which ensures that it cannot be changed unnoticed. The protocol is therefore clearly verifiable for its authenticity by a publicly available procedure. This counterfeit protection is, for example, a character sequence calculated from one or more electronic documents, which is recorded in a written document. The method of calculating the character sequence has the preferable property of being generally known and that it is very difficult or impossible to achieve the same character sequence in different source documents. One such known method is, for example, the MD5 algorithm (RFC 1321).

The guarantee certificate is at least partially encrypted so that the customer does not know or need to know all the information about the performance of the lift system. This is interesting for the lift company because details of the operating parameters may concern operating secrets. The information disclosed is chosen in such a way 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 a written document, both of which are protected against counterfeiting, which also confirms their association.

Err1:Expecting ',' delimiter: line 1 column 212 (char 211)

The written document covers the same as the electronic file, but only a part of the passenger traffic, for example, 15 % of all elevator calls chosen at random.

For verification purposes, the electronic passenger traffic file, i.e. the elevator calls, is entered into the control of the elevator system and the behaviour of the system is recorded in a measurement log, which also describes the allocation of calls to cabins and the movements of cabins and doors.

The written documents are signed in duplicate as part of the purchase contract and exchanged between the lift company and the customer. Depending on the design of the counterfeit protection and/or encryption, the certificate of guarantee is checked for authenticity or integrity by a computer program.

The customer may not be able to access the entire log, but he will receive a list of all cabin and door movements and the cabin assignments of those calls corresponding to the part of the passenger traffic published in the log.

The lift company determines from the measurement protocol the performance characteristics described in the guarantee declarations for the entire passenger transport and for the part of it published in a document, the latter being verifiable by the customer, which can be supported by the lift company with appropriate tools, for example an Excel program.

The review agreement may, for example, provide that both the performance characteristics for total and partial traffic must be covered by the guarantee declarations, in which case the guarantee declarations are chosen in such a way that a corresponding partial traffic is also most likely to meet them.

The steps described are exemplary and do not preclude a similar or more general implementation of the subject matter.
