Description

Remote control of elevator installations Description The invention relates to a system and method for controlling the operation of elevator installations according to the generic concept of claim 1.

For the control of the operation, each installation of elevators is assigned a control device with which sensors and actors are connected, such as, for example, control, drive and regulation elements of the installation. A microprocessor of the local control device reads the input signals and distributes the output signals according to the control program provided. The processing of the signals and of the data stored in the control, which describe the installation of elevators, such as number of floors, type of drive, etc., takes place in a microprocessor placed in situ in the elevator installation.

By the patents EP 0 252 266 Bl and US 5,450,478, elevator installation systems are known, elevators that are equipped, in addition to a conventional control device, with a modem for remote control. The control device of each elevator installation communicates in each case with this remote control, under certain conditions and through a modem via the public telephone network, with a central maintenance or service post. The data exchange provided here refers, first of all, to previously defined diagnostic data regarding operational status, failure events and alarms of all elevator installations connected to the central maintenance or service station.

Depending on the configuration and operating mode, a data exchange procedure has been pre-connected to the exchange of data specific to the installation itself, which, on the one hand, structures the communication path and, on the other hand, regulates access or authorization to access elevator control data.

Although these systems of elevator installations equipped with an individual control system for each elevator, including the extension with a modem and a central maintenance and service station, have given good results, due to their constructive and functional characteristics explained, they are expensive systems in terms of equipment and only a very small selection of previously defined messages can be transferred to the central maintenance and service station. The maintenance and maintenance of the elevator installations, connected in the global system with the maintenance and service center, and which, at times, are physically far apart, entails a high cost. In case of faults in the operation of an elevator installation or an elevator, there are long waiting times until the cause is determined and the fault is rectified in situ.

Therefore, the object of the invention consists in an installation system of the type mentioned above that makes it possible to reduce the service means, reduces maintenance and conservation and extends the service provision.

The objective is achieved, according to the invention, with a system of the features indicated in claim 1. The subclaims contain advantageous developments of the invention from the point of view of the equipment and process.

The essence of the invention consists of a remote control of elevators. For this purpose, a central control device is connected to all the elevators of a system through a data transmission device. The control data and the parameters are communicated between each installation of elevators and the central control station, the latter becoming the state of the sensors in a control signal.

The resulting advantages are that only one central control device is required for all. the elevators of a complete system and in which two traditional controls of the elevators are suppressed. This reduces the cost of equipment and also the space required for the construction of the elevator installation in regard to the building.

By transmitting all the data and parameters of the installation to the central control device of the complete system, centralized maintenance of this technique becomes possible. Time adjustments and on-site adaptations are eliminated in the elevators with a high labor cost. By modifying the software of the central control device, the functions of the elevators are influenced, both for individual elevators and for several elevators. In addition, it is possible to generate a complete real state of the elevator installation in the plant and to centrally correct data concerning user rights, travel destinations, etc.

Furthermore, in the elevator installation system according to the invention, completely new forms of control of the installation and preventive maintenance and maintenance are possible. In addition to the control algorithms, a separate evaluation of the transmitters can be carried out for an analysis of wear and faults. Each constructive group can be analyzed in a preventive way and evaluated statistically. The customer can obtain information about the installation in any way (for example, internet pages through the PC).

An exemplary embodiment of the invention is described in more detail below with reference to the drawings. These show: - Figure 1, a schematic representation of a lift installation with remote control. - Figure 2, a block diagram of a system, r elevator facilities according to the invention. - Figure 3, a flow chart to represent the processing of control information in the installation of elevators. - Figure 4, a flow diagram to represent the processing of the command information in the control center.

The installation of elevators 1 can consist in this exemplary embodiment in a single elevator 20 but also it can be an installation with several elevators 20 connected to each other forming a group for the technical control in a building. The elevator car 3 is suspended by cables 4 which are driven over a drive pulley 5. The drive pulley 5 is set in motion by means of the drive machine 6 which is supplied with electrical energy by means of a control system. drive 7. To control the movement of the drive pulley 5 and, therefore, the position of the elevator car 3 in the recess 2, a sensor whose signal is transmitted to an input / output device 9 is provided.

The elevator car 3 is closed with car doors 10 that drive parallel floor doors not shown. To record the weight of the persons or objects in the elevator car 3, a load measuring device 11 is provided, for example a load measuring floor.
