In a further aspect, the present invention provides a method for computer-assisted furnishing of materials for elevator lift during at least two of the following discrete process stages: a0) order processing; al) production; a2) supply; a3) wholesale; a4) delivery; a5) mounting; and a6) maintenance, wherein the method comprises the steps of: - generating a checklist stored in a databank; - providing a component, a material, a package or a pallet with either a readable and writable data transmitter; -writing data with computer assistance from the checklist onto the data transmitter in at least one of the stages a0-a6; - reading the data with computer assistance from the data transmitter 2b in at least a different one of the stages a0-a6; and - checking the read data against the checklist.
The invention consists of a computer-assisted furnishing of materials in elevator construction, wherein materials are provided with a readable or writable data transmitter, these materials are furnished, data of the data transmitter are written or read with computer assistance and these data are checked with computer assistance.
Advantageously, individual materials or components thereof and/or packaging of materials and/or a pallet of assembled materials is or are provided with a data transmitter. Advantageously, the data transmitter is a contactless chip card with data which are stored in a data store and which are read or written by a read/write device.
Advantageously the data transmitter is an economically producible chip card in the form of a resilient film transponder which communicates on the basis of radio frequency (RF).
The data transmitter can be read or written with computer assistance at any place in the net product chain during elevator construction, i.e. in the order processing, manufacture, supply, wholesaling, delivery, mounting and servicing of the materials.
Advantageously, the data are, for computer-assisted checking, compared with at least one checklist stored in at least one databank. The data read by the read/write device are communicated to at least one evaluating unit and compared by the evaluating unit with the checklist in accordance with at least one computer program product.
The computer program product compares whether these data agree with corresponding details of the checklist. The evaluating unit issues a positive or negative response signal as the result of this checking.
With the invention the individual steps of the net product chain in elevator construction can be checked and quality can be increased at all stages of this net product chain. The details of the checklist stored in the databank lead to a transparency, which simplifies administrative structures.
The invention is explained in detail in the following on the basis of an exemplary embodiment according to Fig. 1. Fig. 1 shows a diagrammatic illustration of the method for computer-assisted furnishing of materials in lift construction. Fig. 1 shows a net product chain consisting of order processing 0, manufacture 1, supply 2, wholesaling 3, delivery 4, mounting 5 and maintenance 6 of materials.
The materials used in lift construction are of numerous kinds. Thus, materials such as guide rails, electric drives, cage components, cables, belts, control boxes, etc., are furnished. The materials are prepared at suppliers, supplied to wholesale warehouses, delivered from there to building sites and incorporated in lift installations.
Advantageously, the data transmitter is a contactless chip card with data which are stored in a data store and which are read or written with computer assistance by a read/write device. The data transmitter is, for example, a transponder with transponder antennae and a transmitter electronic system. The data transmitter is supplied with an operating voltage by induction by way of an electromagnetic field. Such an electromagnetic field is irradiated by the read/write device. As soon as the data transmitter is disposed in the vicinity of the read/write device, it is supplied with energy and transmits data, by way of radio frequency, to the read/write device. According to the respective card type, ranges of the communication are realised from a few centimetres up to one metre and more. The read/write device transmits or receives the data by way of an appropriately constructed transmitting and receiving antenna. The read/write device can be constructed to be portable or stationary. The reading/writing takes place in contactless manner, even through materials or packages.
The transponders can be divided into passive and active forms, wherein the passive forms obtain their energy exclusively by the electromagnetic field built up by the read/write device and the active forms have an own energy supply for amplification of the data transmitted back by radio frequency, and are also divided into read-only, i.e.
readable only, and into read/write i.e. readable and writable, variants. The different systems are moreover distinguished by the radio frequencies used, the constructional form ((adhesive) film, tube, plastic card or similar), the range in the write/read process and the reading speed. The basic information of a transporter is a programmable, worldwide specific numerical code; according to the respective embodiment, the transponders store further data; for example, in the case of read/write transponders, storage of date and time by the read/write device. Film transponders are particularly advantageous, since they are distinguished by low production costs, resilience of the film, simple application, insensitivity in handling and relatively high data transfer rates In particular, such film tags are largely insensitive relative to soiling and painting at the building site.
With knowledge of the present invention, any desired readable or writable data transmitters or read/write devices can be realised. Thus, data transmitters which communicate contactlessly on the basis of light with a read/write device such as a scanner are equally usable. Data transmitters in the form of magnetic cards, electronic chips, etc., which communicate with a read/write device by way of at least one intermediary contact, are also usable.
For the computer-assisted checking of the data, details are stored in a checklist of a databank. These details correspond with the data or these details and data are associated with one another. The databank is, for example, a relational databank.
An evaluating unit is provided for the computer-assisted reading/writing of the data or for the computer-assisted checking of the data. The evaluating unit is a commercially available computing unit with inputs and outputs for communication with a read/write device or with the databank. For example, the communication takes place in accordance with a known standard protocol such as the Internet protocol (TCP/IP) by radio and/or cable and/or telephone. The evaluating unit can be constructed to be portable or fixed.
Evaluating unit, databank and read/write device can be integrated in a single housing, but they can also be separately placed at different locations.
Advantageously, a computer program product is installed in the evaluating unit. With advantage, the computer program product operates in several modes such as configuration mode, production mode, storage mode, delivery mode, mounting mode and maintenance mode, which modes correspond with the stages of the net product chain. The computer program product thus has access to read information and to the details of the checklist. The computer program product compares read data with details of the checklist.
Advantageously, this comparison takes place in accordance with known logic gates such as AND, OR, NOT, etc.
Known and proven input and output means such as a display, a keyboard, a loudspeaker, etc, are integrated in the read/write device or in the evaluating unit. In the case of correct identification or in the case of non-agreement a positive or negative response signal is issued, for example, optically on a monitor or acoustically by way of a loudspeaker. The response signal can also consist in an output of the read data. The computer program product can undertake an interrogation. The issue of such an interrogation can take place optically on the monitor. The acknowledgement of the interrogation, for example by YES/NO, can be effected by way of a keyboard or a monitor with functional surfaces (touch screen).
In the case of the order processing 0, details with respect to the requisite materials, the delivery periods, the number or distribution of pallets, etc., are stored in the checklist. The io computer program product writes these details in a configuration mode into the checklist.
The materials are advantageously provided with a data transmitter in production 1. For example, the data transmitter is incorporated in the materials or applied to the materials.
The data transmitter comprises a data store with production-relevant data for specific association of the materials, such as production number, batch number, production date, production variant, etc. These data are used for production control and allow checking of the course of the production 1 of the materials. In particular, these data allow a quality control during the production 1 of the materials.
The materials are assembled from several components in the production 1.
Consequently, details are present in the checklist that a first component - which has a first production number - is to be combined with a second component - which has a second production number. In the production 1, the production numbers are read and communicated to the evaluating unit. The computer program product compares, in a production mode, the correct combination of the components to form materials. For this purpose the read production numbers are compared with the checklist. For example, the sequence of read production numbers is compared with a corresponding sequence of production numbers in the checklist.
Advantageously, the produced materials are packaged at the suppliers and the packages are provided with data transmitters. For example, the data transmitter is incorporated in the packages or applied to the packages. Supply-relevant data about the content of the packages is written into the data stores of the data transmitters of the packages. For example, data with respect to the content and number of the materials, the production members thereof, batch numbers, production dates, production variants, the envisaged supply date, the weight of the packages, etc., are stored.
In a supply 2 the packages are dispatched to the wholesale warehouse.
Advantageously, the data are read or written at the time of entry into the wholesale warehouses. These supply-relevant data are advantageously stored in the checklist. The data are able to be further processed. For example, the computer program product in a storage mode compares the materials that have entered with a corresponding acquisition order according to the checklist. This allows checking of the completeness of the received materials. In addition, the computer program product actualises the data stored in the data stores of the materials or packages. For example, data concerning the actual supply date as well as a storage number are written into the data stores of the data transmitters. Such actualised data are advantageously similarly stored as details in the checklist.
Advantageously, materials or unpacked materials are assembled at the wholesaler 3 from the wholesale stock in order to be delivered on pallets to a building site.
The pallets are advantageously provided with data transmitters. Logistics-relevant data are written into the data store of the data transmitter of a pallet. For example, data concerning the wholesale number, the point of distribution at a building site, etc., are stored. These logistics-relevant data can obviously also be stored in the data transmitters of the materials or packages of the products. Advantageously, the computer program product assembles the materials, which are to be delivered, in accordance with the checklist and stores these logistic-relevant data as details in the checklist.
In the delivery 4 to the building site the logistics-relevant data of the data stores of the data transmitters of the pallets are read and compared with the checklist. For example, five lift installations are installed at five distribution points at the building site and ten pallets are delivered for each lift installation. Through detection of the logistics-relevant data directly at the delivery, the fifty delivered pallets can be immediately placed at the intended distribution points and the completeness of the delivery checked i.e.
deficiencies in the wholesale stock queried. The logistics-relevant data are read and output. The computer program product compares, in a delivery mode, the read data with details of the checklist.
A reception report of the delivery 4 can - analogously to a radio report (SMS) or an Internet E-mail - take place in the delivery mode. Advantageously the computer program product executes an interrogation such as: Please confirm the completeness of the supplied materials. The interrogation is acknowledged.
For the mounting 5 of the lift installation, the materials delivered in the pallets are specifically identified on the basis of the information in the data stores of the data transmitters in the pallets. These data are used for control in the mounting and allow checking of the progress of mounting 5 of the lift installation. In particular, these data allow a quality control during the mounting 5 of the lift installation.
The lift installation is installed with use of several materials. In the checklist there are accordingly present details such as that a first material - which has a first production number - is to be combined with a second material - which has a second production number. In the mounting 5 the production numbers are read and communicated to the evaluating unit. The computer program product compares, in a production mode, the correct combination of the materials. For this purpose, the read production numbers are compared with the checklist. For example, the sequence of the read production numbers is compared with a corresponding sequence of production numbers in the checklist. It is possible through communication of the data to a central unit to monitor the construction progress and to actualise plans for deployment of personnel.
For the maintenance 6 of the lift installation the data in the data stores of the data transmitters of the incorporated materials are read and compared with the checklist.
Advantageously, all data important for the maintenance or the replacement and a reordering are written as maintenance-relevant data in the data store. For example, the production numbers, production dates and production variants of the materials are read.
The computer program product compares, in a maintenance mode, the read data with details of the checklist. Advantageously, the checklist contains an installation documentation or communicates with an installation documentation. Defective materials or components can thus be specifically identified and the correct replacement parts can be automatically reordered. Advantageously the reordering is carried out in the maintenance mode. The computer program executes, for example, an interrogation such as:
Will you reorder these materials identified as defective? The interrogation is acknowledged.

The computer program product compares, in a production mode, the correct combination of the components to form materials. For this purpose the read production numbers are compared with the checklist. For example, the sequence of read production numbers is compared with a corresponding sequence of production numbers in the checklist.
Advantageously, the produced materials are packaged at the suppliers and the packages are provided with data transmitters. For example, the data transmitter is incorporated in the packages or applied to the packages. Supply-relevant data about the content of the packages is written into the data stores of the data transmitters of the packages. For example, data with respect to the content and number of the materials, the production members thereof, batch numbers, production dates, production variants, the envisaged supply date, the weight of the packages, etc., are stored.
In a supply 2 the packages are dispatched to the wholesale warehouse.
Advantageously, the data are read or written at the time of entry into the wholesale warehouses. These supply-relevant data are advantageously stored in the checklist. The data are able to be further processed. For example, the computer program product in a storage mode compares the materials that have entered with a corresponding acquisition order according to the checklist. This allows checking of the completeness of the received materials. In addition, the computer program product actualises the data stored in the data stores of the materials or packages. For example, data concerning the actual supply date as well as a storage number are written into the data stores of the data transmitters. Such actualised data are advantageously similarly stored as details in the checklist.
Advantageously, materials or unpacked materials are assembled at the wholesaler 3 from the wholesale stock in order to be delivered on pallets to a building site.
The pallets are advantageously provided with data transmitters. Logistics-relevant data are written into the data store of the data transmitter of a pallet. For example, data concerning the wholesale number, the point of distribution at a building site, etc., are stored. These logistics-relevant data can obviously also be stored in the data transmitters of the materials or packages of the products. Advantageously, the computer program product assembles the materials, which are to be delivered, in accordance with the checklist and stores these logistic-relevant data as details in the checklist.
In the delivery 4 to the building site the logistics-relevant data of the data stores of the data transmitters of the pallets are read and compared with the checklist. For example, five lift installations are installed at five distribution points at the building site and ten pallets are delivered for each lift installation. Through detection of the logistics-relevant data directly at the delivery, the fifty delivered pallets can be immediately placed at the intended distribution points and the completeness of the delivery checked i.e.
deficiencies in the wholesale stock queried. The logistics-relevant data are read and output. The computer program product compares, in a delivery mode, the read data with details of the checklist.
A reception report of the delivery 4 can - analogously to a radio report (SMS) or an Internet E-mail - take place in the delivery mode. Advantageously the computer program product executes an interrogation such as: Please confirm the completeness of the supplied materials. The interrogation is acknowledged.
For the mounting 5 of the lift installation, the materials delivered in the pallets are specifically identified on the basis of the information in the data stores of the data transmitters in the pallets. These data are used for control in the mounting and allow checking of the progress of mounting 5 of the lift installation. In particular, these data allow a quality control during the mounting 5 of the lift installation.
The lift installation is installed with use of several materials. In the checklist there are accordingly present details such as that a first material - which has a first production number - is to be combined with a second material - which has a second production number. In the mounting 5 the production numbers are read and communicated to the evaluating unit. The computer program product compares, in a production mode, the correct combination of the materials. For this purpose, the read production numbers are compared with the checklist. For example, the sequence of the read production numbers is compared with a corresponding sequence of production numbers in the checklist. It is possible through communication of the data to a central unit to monitor the construction progress and to actualise plans for deployment of personnel.
For the maintenance 6 of the lift installation the data in the data stores of the data transmitters of the incorporated materials are read and compared with the checklist.
Advantageously, all data important for the maintenance or the replacement and a reordering are written as maintenance-relevant data in the data store. For example, the production numbers, production dates and production variants of the materials are read.
The computer program product compares, in a maintenance mode, the read data with details of the checklist. Advantageously, the checklist contains an installation documentation or communicates with an installation documentation. Defective materials or components can thus be specifically identified and the correct replacement parts can be automatically reordered. Advantageously the reordering is carried out in the maintenance mode. The computer program executes, for example, an interrogation such as:
Will you reorder these materials identified as defective? The interrogation is acknowledged.
