Description
(1) technical field
The present invention is the illumination analysis system based on wireless senser, can be used for the illumination test and quality of lighting analysis etc. in the places such as office, education, business, physical culture and factory building, the figure such as illumination analysis and distribution can be drawn out the short time, contrast with national standard, for designer and relevant industries provide convenient accurate judgement material.System controls computer by multiple survey sensor and one and forms, and sensor strip has wireless module, and measurement data sends to control computer automatically, generates analyzed pattern by the background program of computer.The present invention realizes illumination photometry and is combined with wireless telecommunications, has real-time and practicality, is luminous environment means of testing and the analog meter of innovation.
(2) background technology
Light and people live close relationship, light utilizes discomfort or poor lighting condition to be all cause one of the main reasons that is tired and accident, much directly or indirectly because insufficient light caused in many occupational labor accidents, and for stadium (shop) and educational alternative, the requirement of illumination is more strict, crosses strong or crosses the overall luminous environment that secretly all can have a strong impact on place.
The general available illuminometer of brightness value is measured, and illuminometer can measure the light intensity of different irradiation distance, provides measurement result accurately to people.Particularly hand-held illuminometer can measure the illuminance of arbitrfary point one by one, efficient and convenient, but can not generate the Illumination Distribution figure of multiple spot composition in real time, can not reflect the luminous environment quality of certain space area comprehensively.
Notice the problems referred to above, the present invention proposes a kind of illumination analysis system based on wireless senser, system comprise multiple survey sensor and one control computer, each sensor is with a wireless module, each wireless module arranges unique id number, background program is contained in advance and controls, in computer, automatically to identify the ID of each sensor, distinguishes the source of data according to ID.During work, system sets up the model of measurement space in advance in background program, determine the measuring point number needing to measure, simultaneously, background program distinguishes the source of data according to id number, measurement data accurate calibration in selected model, form all kinds of illumination analysis figure, the overall quality of perceived light environment.
(3) summary of the invention
Form the Illumination Distribution figure of space entirety, the brightness value that first will carry out multiple spot is measured, the figures such as equiluminous curve are drawn again according to certain rules integration, generally onesize space, measuring point distribution is more much more extensive, and the figure represented is more accurate, and existing general hand-held illuminometer many tests single-point, tests other point by mobile illuminometer position, because illuminometer does not contact integration with background program, just data cannot be directly inputted in handling procedure.
The present invention is multiple spot illumination photometry system, by DATA REASONING and background process, each numerical value is presented on the correspondence position of measurement space, and simulation equiluminous curve or other conventional figure, feature is measured value and location matches, avoids measuring point to obscure.After measuring the brightness value of multiple spot, numerical value is inputted automatically and demarcates on tram, to draw correct patterns by calculating simulation.Measured value can not mate with point position, can cause aliasing, finally to the result made mistake.
The present invention sets up the model needing measurement space in advance in background program, observe measurement space size, type and shape, plane subregion is determined according to measurement standard, and selected planar graph and combination thereof in background program, then determine the some number needing to measure, measuring point arranges with the form of array, and some quantity and some interval are with reference to related specifications standard, to ensure data precision, avoid too much invalid measurement simultaneously.
Before measuring, the parameter that background program confirms is six:
1, the type of measurement space and array mode, planar graph comprises rectangle, triangle, trapezoidal and circular, can be combined into the measurement space of any type, first be combined into facet figure, after these graphical set are synthesized final measurement space;
2, the measuring point array of planar graph, the corresponding lattice array of each selected planar graph, array is expressed as a × b, and a be laterally, and b is longitudinal direction, wherein a > 1 and b > 1;
3, arrange the sequence of positions of measuring point and measuring sequence, be first set as horizontal or longitudinal sequence of positions, confirm measuring point every row or often arrange lay order, reset left and right or upper and lower measuring sequence, confirm that sensor can survey complete array;
4, the sensor used and measuring point number, the number of sensor is limited, and array is counted and far may be exceeded number of sensors, needs to reuse sensor;
5, the reference position of sensor and spacing, first setting starting point, is generally first point of array, then sets this distance from border, resets the spacing of each measuring point, measuring point from frontier distance and point and the spacing of point, all to consider codes and standards requirement; Need to measure instrument with ruler or other during placement sensor and measure spacing dimension, so that sensor localization is correct;
6, each often time of measuring, be recorded to date, Hour Minute Second, every minute and second, measurement data is corresponding with the measurement moment.
Survey sensor is wireless standard, and measured value, with a wireless module, is sent to control computer by each sensor, solves the trouble of dragging data line.For guaranteeing measured value and putting the corresponding of position, the present invention takes following two measures:
1, system is that each wireless module arranges unique id number, the corresponding unique ID of measured value of each sensor, and after data are sent to and control computer, background program distinguishes the source of data according to ID.
2, the ID of sensor numbers in order, arranges from small to large, each measurement one group of point, sequence of positions is corresponding with the order of ID, first corresponding first ID of point, by that analogy, if a line/mono-row need repetitive measurement just can complete, sensor ID circulates according to sequence of positions, until surveyed.
Thus, the present invention realizes measured value and the one_to_one corresponding of some position, guarantees the correct distribution of data at areal model, draws the figure such as illumination analysis and distribution provide measured data for accurate simulation.
Measurement data is demarcated after planar graph, and background program, according to the repeated measurement number of times of data, calculates the mean value of each point, and coupled together with smooth curve mean value corresponding point position, form complete illumination curve figure or other conventional figure.Program also available color marks the average illumination of zones of different, viewing area directly perceived difference.The lighting standard of preset different building type in program, judge whether measured result meets standard with this, and provide proposal on adjustments, the Lighting Design for specialty provides strong reference.
