摘要： A fire detection system includes at least two fire detectors having a partially overlapping view of a fire. The at least two fire detectors are configured to acquire fire cluster information related to the fire. A validation and pairing module pairs fire clusters detected by the at least two fire detectors for the fire. The validation and pairing module is configured to validate the paired fire clusters according to a validation process that ensures that the pair corresponds to a fire. A triangulation module determines a three-dimensional fire location for the fire based on the fire cluster information related to the validated fire cluster pairs.

摘要： A flame detector configured for radiant energy monitoring, quantification, and information transmission. The system has at least one optical sensor channel, each including an optical sensor configured to receive optical energy from a surveilled scene within a field of view, the channel producing a signal providing a quantitative indication of the optical radiation energy received by the optical sensor within a sensor spectral bandwidth. A processor is responsive to the signal from the at least one optical sensor channel to provide a flame present indication of the presence of a flame, and a quantitative indication representing a magnitude of the optical radiation energy from the surveilled scene. An Artificial Neural Network may be used to provide an output corresponding to a flame condition.

摘要： A noncontact temperature sensing device receives radiative emissions from a sensed object to measure radiant heat flux and computes a temperature using multiple photodiode sensors, or elements, each sensitive to a different bandwidth of near IR light. The device samples a fluctuating heat source such as a flame or explosion at a fast sampling frequency, and compares corresponding or simultaneous readings in each bandwidth for computing a ratio of the respective bands and determining a temperature via ratio pyrometry. Multiple sensors of adjacent bands each receive corresponding readings of near IR emissions, perform fast, concurrent sampling to mitigate inconsistencies of heat source fluctuations, and compute a temperature based on a ratio between the sampled readings of the different bands. Near IR detection allows common and inexpensive photodiodes to be employed, and the photoelectric rather than thermoelectric sensing allows faster sampling and at a greater distance from the sensed heat source.

摘要： The present invention discloses a method for measuring an actual temperature of a flame by using all information of a radiation spectrum and a measurement system thereof. The method includes: conducting more theoretical data processing by using energy level structure correction, wherein all information of the radiation spectrum can be used; and by way of a keyboard input manner or a data transmission input manner, acquiring an energy level structure correction parameter, and finally acquiring a more accurate actual temperature value of a measured flame. The method effectively overcomes a defect that the true temperature of the flame can be obtained by only conducting radiance correction through data processing with great calculations when adpted multi-spectral temperature measurement method. In the existing multi-spectral temperature measurement method at present, only information of several monochromatic radiation capacities in the radiation spectrum can be used; and in the method, information of all the monochromatic radiation capacities, thousands of monochromatic radiation capacities in general, in the radiation spectrum can be used.

摘要： A flame sensor detects the presence of a flame in a combustion system in which the flame emits light. The flame sensor includes a body connectable with the combustion system. A photodetector is supported in the body. The photodetector responds to light emitted by the flame and generates an electrical signal proportional to an intensity of the light. A window is supported in the body and located between the combustion system and photodetector. The window is susceptible to contamination from the combustion system and the contamination may decrease sensitivity of the photodetector. A light source is supported in the body. The light source emits light so that a predetermined amount of the light emitted by the light source reflects into the photodetector when contamination is present on the window and the photodetector generates a signal indicative of contamination on the window.

摘要： A system and method are disclosed for detecting open flames in an outdoor environment. Structurally, the outdoor flame detector includes both an ultra-violet (UV) detector and a Radio Frequency (RF) detector. While operating within predetermined parameters, these detectors respectively create an event signal(s) and a cancel signal(s). In detail, the UV detector will output an event signal whenever UV radiation with a fluence above a predetermined value is incident on the UV detector. On the other hand, the RF detector will output a cancel signal whenever it receives an RF component transmitted in an electrical arc discharge having an intensity above a predetermined threshold. The event signal and the cancel signal are then individually and collectively evaluated by a computer to distinguish between an actual open flame and a non-flame event, such as an electric arc discharge (e.g. lightening, electric motors and arc welding).
