Definitions
- the present invention relates to a mobile control device and a method for remote control of an elevator installation in its inspection operation or an elevator installation which can be controlled by such a mobile control device or method.
- An elevator system is used to transport people through an elevator car within buildings, namely between different floors.
- the elevator system In order to be able to guarantee the safety of passengers or service personnel, the elevator system must be regularly or periodically inspected and maintained.
- an elevator system For maintenance or for carrying out inspection and maintenance work, an elevator system must be put into an inspection or maintenance mode in which the elevator car is only allowed to travel by manual control at walking speed and, under certain circumstances, only between certain positions within the elevator shaft.
- a service technician normally first has to get into the elevator shaft via a shaft door or maintenance hatch, since a control device, e.g. an operating device, is located in the shaft and is available to manually control the elevator car during maintenance work to be controlled.
- a control device e.g. an operating device
- This control device is to be switched on or off by a toggle switch, usually called an inspection switch. After a maintenance work has ended, the inspection maintenance mode can be ended by deactivating this control device.
- a control device is arranged as a fixed inspection operating device in accordance with the EN81-20 standard on the roof of the elevator car and in the shaft pit of an elevator system, the mobility of the technician during inspection / maintenance work is limited only within the shaft, either on the roof of the Elevator car or in the shaft pit.
- the safety chain is also referred to as a safety circuit. It is the entirety of the electrical safety devices connected in series, such as the door contacts, bolt contacts or contacts of the Safety gear. If one of these safety switches is interrupted, the entire chain is considered interrupted and the elevator is not allowed to move.
- the elevator control can only move the elevator car in the elevator shaft when the safety chain is closed as a whole. After maintenance / inspection work, the elevator system can be switched back to regular ferry operation (normal operation) by switching the control device in the shaft to normal mode and closing or locking the shaft door, as well as by closing the safety chain.
- a technician can set an elevator system into the inspection mode only if he has entered the elevator shaft through a shaft door and has reached the control device.
- the elevator car could suddenly move in spite of the presence of the technician.
- a so-called emergency stop switch is therefore arranged in the shaft next to the shaft door, but mostly only on the ground floor.
- An emergency stop switch is used to immediately bring an elevator system to a standstill in the event of danger or to avert danger.
- One aspect of the present invention can be seen in ensuring the work safety of an elevator installation, in particular in maintenance / inspection work.
- a mobile control device for remote control of an elevator system in an inspection operation
- the elevator system being an elevator car
- the elevator control can, for example, be a central main control of the elevator system, which processes a request signal from an operating panel (COP: car operation panel or LOP: lobby operation panel) and controls the movement of the elevator car accordingly, or it can be a subordinate special control.
- the elevator control can therefore automatically control the elevator car for moving in normal operation of the elevator installation when the safety circuit is electrically closed.
- the safety circuit is electrically interrupted, the elevator car will be blocked for movement.
- the mobile control device can be connected to the elevator system to control the elevator system in such a way that the mobile control device can switch the elevator system to normal operation and / or inspection mode, and that in inspection mode the elevator car can be manually controlled for movement by the mobile control device.
- Automatic control of the elevator car means that the elevator control executes an algorithm or a program after a triggered start signal, which can be a signal generated externally or internally, and thus to carry out one or more process operations of the elevator car.
- Manual control is understood here to mean that the elevator system only reacts to current handling by a person using a switch (e.g. button or button), which directly causes the elevator car to move after handling (after releasing the button or button) the reaction of the elevator system or the movement of the elevator car also ends.
- a switch e.g. button or button
- an elevator car travels under an automatic control at a higher travel speed or a greater acceleration, while under a manual control only at a low travel speed or a lower acceleration.
- a technician can then manually control the elevator car for movement in the inspection operation of the elevator system by operating the mobile control device.
- the mobile operating device can be separated from the elevator system. It is then no longer necessary for an inspection operating device to be available on the roof of the elevator car and / or in the shaft pit.
- the inspection control device or devices can be replaced by the mobile control device become.
- the mobile operating device can be used functionally instead of a local inspection operating device. It is thus possible to switch an elevator system into its inspection mode without a technician having to go into the shaft of the elevator system in particular. Even if a local inspection control unit has already been installed in the shaft of an elevator system, it does not need to be dismantled.
- the mobile control device can also take over the responsibility of the existing inspection control device, namely the control of the elevator system in the inspection mode. If the local inspection control device has an emergency stop switch or an emergency pull-out function, this switch or this shut-off function can, however, continue to function alongside the mobile control device. Such a takeover can take place automatically if, for example, a higher priority is given to the mobile operating device than the inspection operating device. Alternatively, you can start this takeover by the mobile control device manually if you first set up a communication link between the mobile control device and the elevator control. For safety reasons, an emergency stop switch can be left on the roof of the elevator car and / or in the chess pit instead of an inspection control device, even if the inspection control device is no longer required there. If the mobile control device fails or causes an error, the emergency stop switch can be used to interrupt the drive of the elevator system or the movement of the elevator car.
- the safety circuit can be designed as an electrical series circuit which consists of at least one safety element of the elevator system in order to be able to block movement of the elevator car when the series circuit is electrically interrupted.
- the mobile operating device can be assigned to the safety circuit as an additional safety element. If a current flow or current path through the safety circuit is electrically interrupted, a control of the mobile operating device on the elevator system is also broken.
- the safety element is, for example, a car / shaft door contact, bolt contact or contact of a safety catch.
- the mobile control device is also connected electrically in series with the other safety element or elements of the safety circuit.
- a real-time system is created from this, with the mobile operating device communicating with the safety circuit in real time can.
- the mobile operating device can simulate a relay contact, for example, by means of a button on its own or a dedicated software module (dedicated module or apps).
- the safety circuit can be formed by a bus system, such as a wired or wireless bus system, in particular a CAN bus system, wherein the mobile operating device can be assigned to the safety circuit as a bus node.
- the connection can be implemented, for example, using a software module.
- a real-time system for controlling the elevator system in inspection operation is also created via the bus system.
- the elevator control can monitor a switching state of the safety circuit or the mobile control device. If the switching state indicates an error or an unsafe situation, the elevator control can prevent the elevator car from moving.
- the safety circuit and / or the mobile control device for data communication with the elevator control can also be connected in a wired, wireless manner or via the bus system. In this way, a technician in the shaft can always communicate with the elevator system in real time using the latest information.
- the position of the mobile operating device can be determined by the elevator control.
- the mobile control device can be positioned using near field communication (NFC) such as RFID (Radio Frequency Identification) or Bluetooth communication, with the mobile control device possibly using other components or sensors in the elevator system or via communicate with the elevator control via the bus system if the distance between the elevator control and the mobile control device is too far for direct communication.

- a service technician can receive or download all the necessary documentation or information on site at an elevator system.
- he can send recorded data or a prepared test report to a remote control center. This could be helpful for remote diagnosis of the elevator system.
- the mobile control device can be provided with a display for displaying, for example, the downloaded information. For this purpose, other information that is determined by the elevator control or the safety circuit can also be displayed.
- the mobile control device can comprise a switching means for switching the elevator system between normal operation and inspection operation, the switching means being an electromechanical means and / or a software function (e.g. an app or a menu item).
- An electromechanical means is, for example, a simple rotary switch.
- a combined rotary / pressure switch, pressure switch or toggle switch, which are connected in series, are also possible.
- the display of the mobile operating device is a touchscreen, a representation of a button that corresponds to the switching means is provided on the touchscreen.
- the mobile control device can be provided with an emergency shut-off device. This emergency shut-off device can be configured just like the switching device of the mobile control device. Thus, a technician can always take a safety measure during his higher mobility in the shaft.
- a method for controlling an elevator system in which the elevator system has an elevator control and an elevator car and a safety circuit.
- the elevator system in normal operation is automatically controlled by the elevator control when the safety circuit is electrically closed. If the safety circuit is electrically interrupted, the elevator car is blocked from moving.
- the mobile operating device is used to control the elevator system in this way with the elevator system connected that the elevator system is switched by the mobile control device between normal operation and / or the inspection mode, the elevator car being manually controlled for moving by the mobile control device in the inspection mode of the elevator system.
- an elevator system with at least one elevator control and an elevator car and a safety circuit

- the shaft door 12 can be opened or closed alone or together with the car door.
- a door switch 13 is provided on each of the shaft doors 12 and on the car door; with the aid of such door switches 13 it can be monitored whether the respective shaft or car door 12 is currently correctly closed or opened.
- An inspection control panel 10 is available to a technician (not shown) in the shaft 9 for inspection / maintenance work, with which the technician can switch the elevator system 1 to an inspection mode and then manually control the elevator car 3 via the electric motor 8 for movement. For example, a switching position "1" is used for inspection mode and a switching position "0" is used for normal operation.
- a switching position "1" is used for inspection mode and a switching position "0" is used for normal operation.
- two inspection control panels 10 can each be arranged on the roof of the elevator car 3 and in the shaft pit 9a.
- At least one emergency stop switch 11 is provided in the shaft 9, which is located, for example, on an inner wall of the shaft 9 - often close to a shaft door 12 on the ground floor - or on the roof of the elevator car 3 in order to immediately interrupt the operation of the elevator system and consequently the To lock elevator car 3 to move.
- the door switches 13 of the shaft door and car door 12, the emergency stop switch 11 are connected in series as safety elements 5a, whereby a safety circuit 5 formed as a safety chain is only closed as a whole if all door switches 13 are closed and the emergency stop switch 11 is not released. Since all of the safety elements 5a are coupled to the safety chain 5, when one of the safety elements 5a is opened, the elevator car 3 is blocked from moving. If a door switch 13 is open, the movement of the elevator car 3 is considered to be unsafe and is shut down by the controller 4.
