Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a procedure for supplying and modifying the data required in the control system of an elevator and for producing the instructions needed for installation, maintenance and adjustment on a display comprised in the control system.

2. Description of Related Art

Modern elevator control systems make it possible to realize numerous different applications designed to take into account the requirements imposed by the users and purchasers of an apparatus or by its operating process and environment. For example, in door control systems, the operation of signalling devices or the rights of operation can be altered by suitably modifying the elevator control data.

In previously known technology, the changes referred to have been made by changing the circuit card in the control unit which determines the function in question. For this reason, it has been necessary to design special circuits for each application. Similarly, the updating of programs and parameters has required the replacement of memory circuits. Especially during installation and testing, changes have to be made several times.

When carrying out installation, maintenance and repair operations, installers need instructions stored in the memory of the control unit. The extent and degree of detail of the instructions are determined on the basis of the installers' requirements, experience and knowledge. The control unit must be equipped with corresponding memory circuits for each elevator.

When servicing an elevator, the installation personnel often need to make modifications in the programming because of the user's requirements and equivalent reasons. This is generally done via an operator interface fitted in conjunction with the control unit of the elevator. The operator is guided in his actions by instructions given via a display unit fitted in the operator interface. The operation of the operator interface as well as the manner of presentation and extent of the information presented through the display can be modified to suit each operator.

When the elevator belongs to an elevator group certain parameters are common to all elevators of the group. Every elevator in the group has the same group parameters, which must be installed manually to every elevator.

When the control system of an elevator is being installed, the elevator-specific configuration and parameter data are transferred to the elevator control system. Most of this data effects to many different parts of the elevator system. The system needs to know in which floor there is a door, i.e. the allowed landing floors, e.g., in elevator control, in motor control or in door control. After a break in the power supply the elevator must know this data. Some of this elevator-specific configuration may also change after installing.

When constructing a new building the elevators function in a different way as in the normal situation. Many parameters must be changed for construction time use and later to the normal use.

SUMMARY OF THE INVENTION

The object of the invention is to eliminate the problems referred to above and at the same time to achieve a system permitting an installer-friendly implementation of modifications and providing appropriate installer guidance. According to the invention, the program and parameter data of the control system and the instructions for each person carrying out maintenance work are stored in a separate storage unit. When installation, modification or maintenance work is being carried out, a communication link is established between the storage unit and the data storage means of a control unit comprised in the control system, the data stored in the storage unit is read and saved in the control unit and the modifications and actions required by the information read from the storage unit are carried out in the control unit.

In the procedure of the invention, the parameters and configuration of each elevator are set in connection with installation via an operator interface comprised in the control system, using a storage card delivered separately. Similarly, when modifications are made, the corresponding information is supplied to the control system by means of a storage card. In a control system employing serial communication, program and parameter updates are performed using a storage card. The components can be manufactured as standard parts, allowing large production series and simpler and faster testing. The storage card can be used as a means of data storage and transfer when information relating to particular elevator installations is transferred to a service center. Updating this information no longer requires the replacement of memory circuits.

Parameters that are common to all or several elevators of the group are dated simultaneously and in a concentrated way. The operator interface checks which parameters are common to several elevators and takes care that they are all installed automatically to all elevators in the group. Thus it is ensured that every group parameter has the same value in each elevator.

In a decentralized elevator control system the elevator-specific configuration and parameter data are transferred to the elevator control system during the start-up drive. The function of the system can be changed later by changing this data. This information is stored into a non-volatile memory in the operator interface. This memory works as a certain kind of master copy and the other components can read the data from the memory whenever required.

The parameters used during the construction time of the building can be easily installed by the operator interface. Respectively the normal parameters can be installed after the construction has been finished.

The storage card contains failure message texts and the instructions for fault location are loaded in memory, making it easy to produce the fault location instructions relating to each failure message on the operator interface display unit. The instructions can be displayed in the language chosen by the serviceman, and this choice is stored on his storage card. In this application, too, the storage card functions as a means of data storage and transfer when the serviceman gives feedback on the operation, failure density and fault types of an elevator.

According to an embodiment of the procedure, when the operator interface is used without a storage card, it works with basic functions and indicates the associated screens in one language, e.g. English or standard codes. Using a storage card, the language can be selected and the right of operation extended according to the degree of authority of the serviceman.

BRIEF DESCRIPTION OF THE DRAWINGS

In the following, the invention is described in detail by the aid of one of its embodiments by referring to the attached drawings, in which

FIG. 1 illustrates the connections of an operator interface in an elevator control system, and

FIG. 2 represents a terminal used in the operator interface of an elevator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 presents a diagram of the functional connections of an operator interface 3 and an elevator control system 2 contained in an elevator control unit 1. The elevator control system 2 controls the operation of the elevator drive 4, doors 5 and indicators 6. Connected to the elevator control system are also the landing and car call buttons 7 and 8. Placed in the elevator control unit is an operator interface terminal 11, by means of which the functions of the elevator can be tested and monitored. The configuration and the parameters can be changed by means of the operator interface terminal 11. The operator interface observes when the parameter concerns the whole elevator group. When a group parameter is changed, the control unit checks that parameters are changed in every elevator control unit of the group. The operation can also be monitored and controlled from outside the elevator control unit by means of a separate terminal 9 or a modem 10. The elevator control unit may also incorporate a group control system controlling the operation of a group of several elevators. In the operational hierarchy, the group control system is above the elevator control system.

As shown in FIG. 2, the operator interface terminal 11 is provided with a keypad 12 which can be used to give functional commands to the various units of the elevator. The instructions given by the elevator control system and the operator commands can be read in the display 13. The terminal also contains indicator units showing the operation and status of the elevator and its parts, e.g. indicators showing the car calls 14, door operation 15 and car position. According to the invention, the terminal 11 is provided with a connector 16 for the connection of a storage card 17 to the terminal. The connector 16 is linked with the internal address and data bus of the terminal.

When the control system of an elevator is being installed, the elevator-specific configuration and parameter data are transferred to the elevator control system by means of a storage card 17. Thus, the elevator components can be supplied separately and even from a different production unit. The elevator-specific information can be easily transferred to a service center by means of a storage card.

Parameters that are common to all or several elevators of the group are dated simultaneously and in a concentrated way. The operator interface checks which parameters are common to several elevators and takes care that they are all installed automatically to all elevators in the group. Thus it is ensured that every group parameter has the same value in each elevator.

In a decentralized elevator control system the elevator-specific configuration and parameter data are transferred to the elevator control system during the start-up drive. The function of the system can be changed later by changing this data. This information is stored into a non-volatile memory in the operator interface. This memory works as a certain kind of master copy and the other components can read the data from the memory whenever required.

When constructing a new building the elevators function in a different way as in the normal situation. Many parameters, such as door closing times, acceleration, deceleration and driving velocity of the elevator car must be changed for construction time use.

When a serviceman starts his work, he will first insert his storage card 17 into the connector 16 provided in the operator interface terminal 11. A processor in the control unit reads the information from the storage card 17. This information has been drawn up for the particular service task and/or is personal according to the degree of authority of the person in question.

The storage card 17 contains the data for the verification of the operator's right of operation, the passwords and the extent of operations permissible to the operator. The storage card 17 determines the language of the texts to be displayed as well as the extent and degree of detail of the instructions to be given to the operator. In this way, each operator is given instructions specifically adapted to the person in question. A person's authorization can also be easily updated by altering the information stored on the personal storage card.

In the case of changed needs, some of the elevator-specific parameter data have to be modified. By using a storage card 17, the new data can be transferred and the updating carried out without removing the memory circuits in the control unit. Updating becomes simpler and more reliable because the update can be tested beforehand. Along with the updated data, the storage card also carries the programs and instructions needed in the updating process.

The storage card 17 intended for the serviceman contains the failure message texts and the instructions for fault location. The instructions are always available and relate to the situation at hand. The instructions are tailored according to the installer's requirements and wishes. The storage card also serves as a means of transferring feedback data from the operator to the service center and production process for further development of activities.

The functions mentioned above can be placed on one or more storage cards, depending on the need and the operator's degree of authority.

The invention has been described above by the aid of one of its embodiments. However, the presentation is not to be regarded as limiting the invention, but instead the embodiments of the invention may vary within the limits defined by the following claims.
