Definitions

  • the present invention relates to a method and arrangement for remotely monitoring and/or controlling the operation status of an industrial lighting fixture.
  • the invention is especially suitable for use in connection with lighting fixtures, such as industrial lighting fixtures, located on the ceiling of high industrial buildings, or in connection with other lighting fixtures that are not easily accessible, such as street lamps.
  • the term industrial lighting fixture is used to describe, in addition to lighting fixtures used in industrial buildings, also lighting fixtures used in warehouses, buildings for commercial purposes, hospitals and other large buildings as well as street lamps and, more generally, lighting fixtures that are not easily accessible.
  • Patent application GB-2176640 discloses an apparatus for determining the operational status of equipment, especially a street lamp.
  • the apparatus comprises a control unit having a plurality of sensors. Each sensor senses a faulty operational state of the equipment. Further the apparatus comprises transmitter, receiver and interrogator. The transmitter transmits a signal to the receiver in the remote interrogator. The signal indicates the operational status of the equipment and identity of the sensors.
  • the receiver is preferably a part of interrogator into which the received information, i.e. the identity indicator and the information concerning the operational state of the respective item of equipment, is stored.
  • the interrogator is preferably a hand-held unit having a control panel and a display to display the status of an item of equipment under interrogation. Further the interrogator can communicate with a computer, which may read the memory of the interrogator and analyze the information obtained.
  • a drawback is that the apparatus is a complicated analyzing system.
  • the object of the present invention is to facilitate a method and arrangement for avoiding the problems and deficiencies of the prior art systems and to simultaneously facilitate an improved method and arrangement for remotely monitoring and/or controlling the operation of an industrial lighting fixture.
  • Another object of the invention is to facilitate a systematic and documentable - and thereby a statistically valid - system for monitoring the condition of industrial lighting fixtures and servicing them.
  • the invention is based on the idea that in order to remotely monitor the operation status of an industrial lighting fixture suitable transducers are used for identifying the factors affecting at least two different operation statuses of a single industrial lighting fixture, such as various components causing a fault condition and/or factors or components affecting or disturbing the optimal operation status and that the fault condition with its cause is indicated wirelessly by means of suitable transmitters using electromagnetic signals, such as LEDs, extra bright LEDs or infrared transmitters etc.
  • the reduction of time required for performing service work is one advantageous feature of our invention. Utilizing the invention will cause an improved flow of information for service work, thus also improving safety during maintenance.
  • the need to actually physically go to the lighting fixture will be reduced, because in a fault condition the lighting fixture need only be accessed once, and only the component to be replaced must be taken along.
  • the invention eliminates the need for the service person to first go and verify the faulty component, then to order the part and to actually repair the problem only after all this.
  • the invention uses the idea that the condition of an industrial lighting fixture can be monitored by means of durable transmitters or indicators, such as LEDs. Using such a durable indicator will solve the problem of unreliable indicators.
  • a failure in the operation of a lighting fixture located on the ceiling of an industrial building and its cause can be identified from the floor, whereby the service person can prepare for repairing the lighting fixture without the need to access the device for identifying the problem.
  • the invention will greatly reduce, for example, the amount of necessary service work, because the device will indicate the problem.
  • Sometimes the normal operation in an industrial building will have to be ceased for the duration of servicing the lighting fixtures.
  • the present invention will reduce the time needed for servicing the lighting fixtures, whereby the time available for the actual work in the hall is increased.
  • One of the advantages of the present invention is the ability to perform pre-emptive maintenance.
  • the service person When the service person is near the ceiling of the building to repair a faulty lighting fixture, another lighting fixture might be nearby for which it is reasonable to change a component, even if there has so far not been an actual fault. If the still operational component that would have to be replaced soon in any case, can be identified in time and replaced together with other maintenance work, the number of service accesses can be clearly reduced.
  • existing operation problems can be dealt with by replacing correct components while any future faults can be dealt with by replacing any necessary components in time.
  • a systematic wireless service and/or surveillance system presents remarkable advantages in modem industrial plants and other large buildings, such as malls, hospitals or in connection with the street lamp network. Service and spare part costs will be reduced as the targeting and anticipating of service work is improved. Any systematic faults or other factors affecting the optimal use of the monitored lighting fixtures can be identified with statistical methods by using the data collected from each lighting fixture. It has previously been impossible to utilize the advantages of such systematic wireless data acquisition for monitoring industrial lighting fixtures and assessing their operation.
  • the apparatus to be installed in connection with the lighting fixture is a complete, independent unit that does not require an external computer or other unit, but the apparatus is capable of stand-alone operation.
  • another advantageous embodiment of the invention utilizes a receiving apparatus for receiving and, for example, systematically recording the data.
  • One of the advantages of the method and arrangement according to the invention is that the apparatus does not require a separate battery for operation, but it takes the necessary power from the electrical network of the lighting fixture.
  • Our invention is also based on the idea that, for example, an LED or other transmitter will wirelessly indicate the condition of various parts of the lighting fixture by being either continuously or intermittently lit.
  • the LED can for example indicate various fault conditions of different components by emitting various signals.
  • the indicated faults can, for example, be overheating of the reactor, breaking of the starter of the lamp or breaking of the lamp.
  • the apparatus will disconnect, if necessary, the lighting fixture from the electrical network.
  • a lighting fixture according to the invention can also be connected to or provided with a component for connecting it to and disconnecting it from the electrical network at exactly the zero point of the voltage and/or current.
  • the sine wave form of AC electrical power causes voltage and current to be zero 100 times per second.
  • the advantage of connecting the lighting fixture to the electrical network at exactly the zero point of the voltage and/or current is that as there will be no arcing over the points during connection, the contactor (relay) connecting the lighting fixtures to the network will be operating under a lighter load.
  • the advantage of disconnecting during the voltage zero point is that the compensation capacitor (if any) in the lighting fixture does not retain any residual voltage, whereby there will be no voltage in the plug of a lighting fixture having a plug after disconnecting. This improves safety.
  • An apparatus comprises, as illustrated in figure 1, transducers 10 monitoring the status of an industrial lighting fixture 1, a transmitter 40 for indicating the cause of the fault, the electronics unit 30 for coordinating the function of the cause of the fault status, transducers and transmitters, means 20, such as a relay, for disconnecting the electrical device from the network, and if desired, a receiver 50 for receiving the signal indicating the operation status.
  • the invention is based on the idea that a durable transmitter, such as an LED or an infrared transmitter will start transmitting a signal intermittently, continuously or when desired, upon activating the transmitter subsequent to the occurrence of the fault.
  • the transmitter utilizes different signals for indicating the cause of the fault.
  • the causes to be indicated and the corresponding signals could be, for example, overheating of the reactor, indicated by fast blinking of the LED, breaking of the starter, indicated by slow blinking of the LED, and breaking of the lamp, indicated by the LED being continuously lit.
  • the phrase "different operation statuses" means in this context the normal operation of the lighting fixture or fault conditions caused by various factors or conditions affecting the optimal operation status of the lighting fixture.
  • the components causing the fault condition can be various components of the lighting fixture, and the factors affecting or disturbing the optimal operation of the lighting fixture can either be various components of the lighting fixture or changes caused by an external factor, such as a change in the ambient temperature. According to the invention it is therefore also possible to monitor and detect external factors and to indicate fault conditions or a non-optimal operation status caused by them.
  • a fault condition or a non-optimal operation status and the cause thereof will be wirelessly indicated by means of transmitters utilizing electromagnetic signals.
  • the term transmitters is understood to cover a wide array of transmitters, transmitter-receivers or the like.
  • a transmitter of this kind is, for example, an LED transmitting a light signal, and an infrared transmitter.
  • the lighting fixture can, if necessary, be controlled to disconnect from the electrical network or to connect to the network at advantageously exactly on the zero point of the current and/or voltage. It is often advantageous to disconnect the lighting fixture from the electrical network in case of a fault condition, depending on the component causing the fault.
  • the lighting fixture is reconnected to the network when needed, for example after identifying and repairing the problem or when the pre-emptive maintenance has been performed. Disconnecting from and connecting to the electrical network at zero point of the voltage will reduce the wear of the contactor (relay) connecting the lighting fixture to the network by reducing its load, as there will be no light arc over the points during connection.
  • a receiver means any suitable receiving apparatus, a transmitter-receiver or the like, and the receiver can, for example, be the human eye or receiver/data recorder suitable for receiving and storing an infrared signal.
  • the transmitter is an LED, which emits a light signal that is detected by a person on the floor level.
  • the transmitter indicating the operation status will only transmit the operation status report to the receiver when necessary, for example, when activated by an activating apparatus installed in the receiver.
  • the system can comprise an electronics unit for coordinating the operation of the transducers and transmitters as well as means for disconnecting the lighting fixture from and connecting it to the electric network at exactly the zero point of the voltage and/or current.
  • the means can be, for example, a relay.
  • the system can comprise a receiver for receiving the status indicator signal.
  • a receiver for receiving the status indicator signal.
  • the identifying data of the cause of the fault condition or the component affecting the optimal operation status are received by a receiver located on floor level.
  • a separate identifying code can be arranged for each monitored lighting fixture.
  • the code can for example be an identifying number that is transmitted to the receiver in connection with each status report.
  • the receiver will store, and if necessary, print out a status report for each monitored lighting fixture.
  • the status reports of the receiver are stored on a computer, the data contained by the reports can be processed with the desired statistical and/or other methods, whereby it is possible to get an overall impression of the operation of a large number of lighting fixtures in various places and during different periods.
  • the transmitter indicating operation status comprises suitable means for activating the transmission of a status report, for example by means of an activation signal sent by the receiver.
  • the system according to the invention is arranged essentially in connection with the lighting fixture to be monitored and/or controlled.
  • the system is easy to fasten on the lighting fixture by means of suitable components, whereby the system can be easily attached to the desired lighting fixtures as an accessory.
  • the system can also be easily removed from the lighting fixture if necessary.
  • the transmitter unit can later be attached either permanently or for a certain period of time.
  • At least one LED is utilized for monitoring the operation status of an industrial lighting fixture and/or identifying the component causing the fault, whereby one LED is used for indicating at least two statuses: for example, overheating of the reactor is indicated by a fast blinking of the LED, while breaking of the starter of the lamp is indicated by a slow blinking and the breaking of the lamp is indicated by the LED being continuously lit.
  • the invention will also improve the safety of industrial lighting fixtures, as they can be disconnected from the electrical network, when necessary, whereby the broken component will not cause additional hazards to the lighting fixture or the environment.
  • the invention expedites recommissioning of the lighting fixture.
  • excessive reducing of lighting efficiency can be detected in time, and so maintenance and repair work can be performed on time.
  • a relay or some other device will disconnect the lighting fixture from the electrical network when the transducers detect a problem, whereby any dangers caused by overheating can be avoided.
  • Some prior art solutions have used the reactor's own thermal relay for disconnecting the reactor in case of a problem. When using an apparatus according to the invention, a separate thermal relay for the reactor is unnecessary.
  • An advantageous embodiment of the invention is the use in lighting fixtures used in high industrial buildings.
  • the invention can especially be utilized in lighting fixtures that are not easily accessible, but it can also be utilized in groups of lighting fixtures with a number of lighting fixtures to be monitored.
  • the method and apparatus are especially well suited for use in discharge lamps lighting fixtures, such as high-pressure sodium lamps, multi-metal lamps and mercury lamps.
