Definitions

  • the invention relates to a method and a device for optical signaling. disturbances of a heating installation or part of a heating installation heated.
  • Heating installations using fuel oil, gas or other fuels to produce heat are used both in homes and in industry.
  • the gas and oil heating installations in particular include a burner used to start and maintain the combustion process.
  • the diet of start-up and burner operation are normally checked from automatically.
  • a device for optical signaling of disturbances of a heating installation in particular a functional breakdown of the installation of heats up following a functional burner shutdown, where the fault is signaled thanks to the uninterrupted lighting of a luminous medium.
  • the device detects the type of disturbance, assign a number to the various possible disturbances and display the number concerned in a look by spinning a wheel carrying the numbers on its circumference.
  • the invention aims to create an electronic monitoring system for a heating installation which goes from any mechanical display device and nevertheless allows a diagnosis easy disturbances.
  • the present invention therefore has the task of proposing a method for the optical signaling of disturbances in a heating installation or part a heating installation, in particular a burner.
  • a second task of the present invention is to provide a suitable device substantially free wear and the components of which are as compact as possible.
  • the appearance and the type of a disturbance functional are detected by a microprocessor, then data relating to a signal assigned to the type of disturbance are recorded in a memory, said signal being viewed periodically or on call through an optical display.
  • the signal is displayed after one or more time intervals following the appearance of the disturbance, by example after one minute, ten minutes or thirty minutes.
  • a display call can be done one or more times instead of or in addition to this.
  • the signal is in the form of a series of pulses attributed to the type of disturbance concerned, which is transformed at the level of the optical display into a series of optical pulses, preferably bright.
  • Optical displays can include, for example, light emitting diodes or incandescent lamps. Preference is given to variants of the process whereby a number of pulses light, preferably light pulses of equal duration, are attributed to each of the disturbances.
  • the optical display signals the appearance of a disturbance first by a continuous signal and does not emit the series of pulses assigned to the type of disturbance only after the display call entered by the operator.
  • Continuous signal means, for example, uninterrupted ignition one or more light emitting diodes.
  • the call to display the series of pulses assigned the type of disturbance is triggered by a button.
  • the same button is also used to reset operation of the heating installation or the relevant part of it heating installation.
  • This interval can be defined, by example, by a duration of 3 to 5 seconds.
  • a series of light pulses can be synonymous with a single light pulse.
  • a single light pulse means that a pressure switch signaled a fault before the blower started and that a disturbance therefore occurred.
  • Another example of the meaning of a series of light pulses is that of a series of six light pulses.
  • the flame went out during the burner operation.
  • there are several causes of faults thus generating the display of several different series of light pulses.
  • the display call of the series of pulses can be repeated at will by pressing the button as described above. However, pressing the button for a period of time less than 3 seconds, does not trigger any fault display, but a restart of the heating system.
  • the signals optics appearing on the optical display are replaced or supplemented by sound signals generated by a sound source.
  • the device comprises a microprocessor for detecting the appearance of a disturbance and the type of disturbance, and at least one memory to record data relating to a signal assigned to the type of the disturbance, knowing that the microprocessor can activate an optical display at using the signal corresponding to the data. Preference is given to a variant of the device according to which the signal consists of a series of pulses attributed to the type of disturbance concerned which can be transformed into a series of light pulses at the optical display.
  • the memory of data can be a memory component commonly used in microelectronics, or it can also be integrated into the microprocessor. Memory data may possibly be subject to the application of a voltage feed.
  • the device comprises a transistor allowing activate the optical display from the microprocessor.
  • the microprocessor and the transistor or the transistor and the optical display can be linked together, by example, using electrical cables and other electrical components such as electrical resistors or integrated circuits.
  • the display optic has one or more light-emitting diodes, red of preference.
  • a preferred variant includes a button allowing the display call of the signal assigned to the type of disturbance. It is therefore particularly preferable that the button and the optical display are integrated together in a component electric.
  • a microprocessor for detecting the appearance and type of a disturbance.
  • a microprocessor is space-saving and, provided that cooling is provided sufficient, works reliably and especially in continuous operation.
  • the various causes of disturbance can be signaled, by example, by means of color light signals or color combinations different. It is also possible to signal the presence of a disturbance by a light signal of a light means and the cause of the disturbance by a signal light of a second light means. In the interest of reduced dimensions, we uses light-emitting diodes for this purpose, possibly colored different.
  • Figure 1 shows a heating installation 2 comprising a burner 3 and a device for the optical signaling of disturbances of a heats 2. These disturbances are expressed in particular by an undesirable stopping of the heating system 2.
  • Device 1 has one or more diodes 5 LEDs connected in parallel.
  • Figure 2 shows a view in enlarged perspective of the device 1. For a better understanding, the view is schematized and largely simplified.
  • a microprocessor 4 which controls the operation of the burner 3 and triggers, as soon as the appearance of a disturbance, the uninterrupted lighting of a diode light-emitting 5 integrated in the button 7.
  • the microprocessor 4 activates the light-emitting diode 5 via the transistor 6.
  • the electroluminescent electrode 5 is on information about the type of disturbance is continuously stored in the data memory 8.
  • the microprocessor 4 having received the control signal, defines the number of pulses to emit.
  • the microprocessor 4 is connected to the transistor via a line electric 9, said transistor being connected to the light-emitting diode 5 by through another power line 9.
  • Figure 2 further shows lines 9 between the microprocessor 4 and the electric closing contact incorporated in the component of the button 7, as well as between the microprocessor 4 and the data memory 8.
  • the term power line used here means also a chain of partial electrical connections comprising other interconnected electrical components.
  • the device according to the invention allows, upon the intervention of a functional disturbance, reliable display of the appearance and type of disturbance of a heating or part of this installation.
