Definitions
- the invention relates to a device for monitoring an operating state of a
- Control device of a passenger conveyor system a method for monitoring a
- a device is known from JP2002197215 which taps the state of an elevator system from the system by means of a device in order to subsequently transmit this state to a remote unit.
- the object is achieved by a device for monitoring an operating state
- Control device of a passenger conveyor system a method for monitoring a
- the device for monitoring an operating state comprises a
- Control device of a passenger transportation system a detection unit for generating a first electrical variable as a function of a signaled state of the control device.
- the device further comprises an evaluation unit for analyzing the first electrical variable in relation to the operating state of the control device.
- the device also includes an interface for transmitting a second electrical signal, which is dependent on the analysis and is generated in the evaluation unit.
- the detection unit is a conversion device for converting an optical signal of at least one optical indicator of the control device into the first electrical signal.
- the passenger transportation system is preferably an elevator or escalator system.
- the evaluation unit is a voltage source with a fixed output voltage.
- the conversion device is a photoelectric element, for example a phototransistor, preferably a photoresistor, which is connected to the voltage source (evaluation device).
- the photoelectric element has a different state (for example a different resistance).
- the resistance of the photoelectric element is the first electrical quantity in this embodiment. The current that flows through the photoelectric element due to the
- Output voltage results, changes depending on the state of the optical identifier. This current is the second electrical quantity.
- the interface for transmitting a second electrical variable, which is dependent on the analysis and is generated in the evaluation unit, can be in the previously described embodiment of the
- Evaluation unit can be designed as two terminals for leading the current mentioned (second electrical variable). An analog transmission of the second electrical variable takes place via cables which are connected to the terminals. The second electrical variable can then be further analyzed and processed outside the device.
- Such a device makes it possible to digitize a state of the control device without having to tap an electrical signal from the device. It just becomes an optical one Signal (or more), which is indicated in the control device, for example by an LED (or more), detected by the conversion device. The information from the optical indicator is thus converted into one (or more) electrical quantity, which can then be easily evaluated. There is no need to intervene in the existing control device, which, among other things, makes it impossible to damage the control device.
- the device thus enables a simple and non-intrusive possibility to digitize status information from old control devices.
- digital services can also be offered in a simple manner for already existing passenger transport systems, which is otherwise only possible for new systems with specially provided interfaces.
- the use of service technicians can be better planned by digitizing the optical status information.
- the service technician can get a first picture of the system based on the digitized status information transmitted in this digital form. This is done in the same way as on-site overview, when the service technician quickly uses the optical indicators to determine where the potential problem could be. Thanks to the device, the service technician can do this remotely. Based on the visual status indicators, it can be concluded what kind of disturbance it could be. In this way, the service technician can already plan his deployment in the service center and organize any material that may be required, so that an efficient service deployment is then possible.
- the detection unit is designed as a photoelectric element, which generates an analog electrical signal as a function of the detected optical indicator, and an analog / digital converter, which converts the analog signal into a digital value.
- the first electrical variable is this digital value.
- the evaluation unit is a microprocessor, which processes the digital value and prepares it for transmission. The processed value is in this
- Embodiment the second electrical quantity. It is transmitted via the interface for transmission, which is designed, for example, as a communication unit. This can be done via the Internet, for example, so that the second electrical variable is available at a location remote from the device.
- the processing of the converted optical signal can therefore take place almost exclusively outside the device (first-mentioned embodiment) or almost exclusively within the device (second-mentioned embodiment). Any gradation is possible.
- the conversion device comprises a photoresistor and / or a camera. In a preferred embodiment, the conversion device is in one
- Controller housing attachable.
- the conversion device is designed in such a way that a plurality of optical indicators can be monitored in the control device housing.
- a camera enables the detection of a wide field of view and, through image processing, the recognition of all conceivable optical indicators and their
- Photo resistors and one or more cameras thus enable the detection of a large number of optical indicators. For example, there may be a photoresistor for each of the classic optical indicators, that is to say in almost every control device. Each of these
- Photoresistors are used to detect a specific optical indicator. Besides these
- Photoresistors can be provided with a camera which is oriented relative to the photoresistors such that all other optical indicators not detected by a photoresistor, for example indicators specific to the control device, are recorded by the camera.
- a flexible conversion device is thus provided, with which a large number of different control devices can be reliably detected.
- the conversion device has a plug-in device which can be plugged onto at least one optical indicator of the control device.
- the plug-in device which in the plugged-on state faces the optical indicator to which the plug-in device is plugged, has a photoelectric element for monitoring this indicator.
- the conversion device can thus be ensured that the conversion device is correctly positioned with respect to the optical indicator (or more). In particular, it can thus be ensured that the conversion device is placed at a distance from the optical indicator, in which the reliable detection of the optical indicator is possible without any problems. It can be further guaranteed that the photosensitive surface of the photoelectric element faces the optical indicator.
- the plug-in device of the conversion device is designed such that the photoelectric element (or more) comes to lie directly on the corresponding optical indicator, for example an LED. This ensures that the photoelectric element can detect the respective optical indicator easily and without interference from other optical indicators.
- a plurality of photoresistors are used, the
- Photo resistors are designed for different frequency ranges. For example, there may be a photoresistor for the detection of red LEDs and a photoresistor for the detection of green LEDs.
- the conversion device is designed as a plurality of photoelectric elements that can be plugged onto LEDs.
- the plug-in device has, on a second side, which, when plugged in, faces away from the optical indicator to which the plug-in device is plugged, a camera for monitoring at least one further optical indicator.
- optical indicators present at other locations can also be monitored through the wide field of view of the camera.
- a method for monitoring an operating state of a control device of a passenger transportation system also leads to the achievement of the object.
- the process includes the steps
- Optical monitoring preferably continuous optical monitoring, of at least one optical indicator of the control device.
- control device states without the need for electrical intervention in the control device.
- the method thus enables the condition of existing systems to be recorded subsequently in a simple and cost-effective manner.
- the electrical quantity corresponds to the optical indicator and therefore provides information about the state of the control device.
- the detection of a change in state of the optical indicator comprises the detection of changes in color and / or pattern of changes in state. The detection can in particular recognize the on-off pattern and / or
- the detection can also include the detection of a single switch-off and / or switch-on.
- the detection includes the detection of all common changes in state of optical indicators.
- the evaluation of the detected state changes serves to define states of the control device in a learning phase of the method.
- the method can be applied to any control device without having previously studied the control device and its optical indicators.
- the method learns on the basis of predominantly prevailing states and possibly data from further sensors of the passenger transport system, which indicator represents which operating state in which state.
- the learning phase can be supplemented, in particular, by data from a central server and the large number of patterns available as a result.
- the evaluation of the detected state changes serves to identify fault states of the
- Passenger conveyance system allows without having to tap electrical signals from the control device.
- the method further comprises the step of transmitting the detected changes in state to an entity outside the passenger transportation system.
- the method further includes the step of resetting the control device upon detection of a specific fault condition of the control device.
- a method for retrofitting an existing passenger transport system also includes the step to solve the problem:
- Control device of the passenger transportation system so that optical indicators of the
- Control device can be detected.
- the device is preferably a device as described above and below.
