IR236 infrared fever sensing system ?unclassified?, ?solved?, ?unsolved? or ?other objects?). after classification, the small icon before each alarm record will be with different indication accordingly. when the classification work is finished, the administrator can summarize different types of alarm within a certain detecti ng period by using advanced function. note: if you want to review the alarm pict ure (with temperature data) from its saving directory in pc harddisk, you shall review it with the help of guide analyser software (you can find it from pc desktop). 3.8 how to judge temperature is exceeding there a r e three methods to judge whether the temperature of a passenger in the thermal video has exceeded the preset temperature standard or not: 1 judge by the temperature: the temperature alarm range can be set as 37.5 42.0 . when a passenger is passing by IR236 camera with a high temperature exceeding 37.5 , the system will produce alarm information automatically. 2 judge by color: when a passenger is passi ng by with fever, the color of his face will be red in a large scale which is much easier to judge. 3 judge by temperature measurement: using single spot measurement method to measure the surface temperature of forehead(for details, please refer to 4.3). if the value reaches 37.5 (this value has already been adjusted as the inner temperature of this passenger), then this passenger can be judged as in fever. the second method is taking advantage of the auto-tracing f unction of IR236 (for detailes, please refer to 4.2). the system can automatically tr ace the hottest spot of t he whole video image. when the highest spot is on the forehead of any passengers and reaches 37.5 , then the passenger can be judged as in fever. 3.9 reason of alarm failure the main re asons of alarm failure caus ed by software of IR236 are as follows: 1 since the temperature of patients with fever is from 37.5 to 42.0 , so the system alarm range is preset to be from 37.5 to 42.0 . if the target temperature exceeds 42.0 , the system will not produce alarm. 2 the system has preset the minimum area of alarm target. therefore, if the target area is much smaller than people?s forehead, such as ci garette ends and flame of cigarette lighter, 36
IR236 infrared fever sensing system 37 the system will not produce any alarm, even if the target temperature is between 37.5 and 42.0 . 3 the hardware becomes loose or the field wiring encounters serious interference will also cause the imperfect performance of the video and si gnal transmission quality. (please contact with wuhan guide if any of the above problem occurs)
IR236 infrared fever sensing system 3.10 quick guide to use the software 1 everyday when the monitoring center is power on, the computer of each monitoring desk will be automatically power on and ru n the temperature sensing programme simultaneously. after 15 minutes of preheating, the syst em enters into normal work condition, measuring temperature and producing alarm if any. 2 the computer produces alarm sound and alar m light flickers to remind operator. 3 the operator shall check the location of r ed cursors on real-time thermal image. if the cursors locate at the following places , the operator could ignore the alarm a belongings of passengers, such as bento, cup with hot water, hand bag b cell phone in use with high temperature c neck of passengers 4 if the cursor locates on the head of one passenger and his body temperature is obviously higher than other passengers, the operator shall identify the passenger?s feature in visual image and f ound that passenger in crowds according to the cursor?s location 5 if the red cursor disappears on real-time thermal image, it means the passenger with high temperature has left the field of view. please check the red cursor on history thermal & visual alarm images (previous alarm images)saved automatica lly by the system. 6 press button ?menu? and then button ?alarm reco rds? to search previous alarm images and the alarm targets with high temperature. 7 classify alarm images into different ca tegories from the alarm image browsing page according to actual conditons. the flow diagram of alarm treatm ent is as shown in figure 1-10: 38

IR236 infrared fever sensing system chapter 4 software using help?advanced setting if you are skilled enough in basic software operation method and want to know about advanced applications, such as adjusting m easurement parameter setting, etc, you should enter into advanced setting inte rface and so corresponding operations. advanced software setting has close relationship with measur ement accuracy, therefore it is necessary for the operator to log in before any advanced oper ation. press button ?setting? on the lower left side of ?paramet er setting? dialog box, ?log in? dialog box will spring out as shown figure 2-1. figure 2-1 operator log in the default user name is ?a?, and default password is ?a?. input correct account and code, press ?confirm?, an ?advanced setting? dialog bo x will spring out as shown in figure 2-2. notice: temperature measurement parameter of advanced setting needn?t to be changed once it is correct. note please do safekeeping to the account and password. in advanced setting, adding new account and password is available. one feature of IR236 is to save para meter change after setting and saving, so measurement parameter needn?t to be changed by general operators. 40
IR236 infrared fever sensing system figure2-2 ?advanced setting?dialog box from advanced setting, the oper ator can adjust measurement parameter of IR236 camera, make focus setting, set alarm parameter, alarm effective area, and correction coefficient of thermal and visual image, etc. note advanced setting parameters are set by technicians in field and debugged when being assembled at the first time. do not make any change if you are not sophisticated enough. 41
IR236 infrared fever sensing system 4.1 temperature measurement principle & method IR236 has two measurement modes: shutter measurement and black body measurement. shutter measurement: when the detector built-i n shutter is compens ating, measure the target temperature by getting the relati onship between thermal image data and target absolute temperature blackbody with constant temperature: use fixed blackbody wi th constant temperature as reference, get the temperature through build ing target temperature model in thermal image shutter and blackbody m easurement has its own re spective advantages and disadvantages. by utlizing camera shutter, shutter measurement results are stable after IR236 is running for twenty minutes, for the detetor needs to get stable performance step by step. therefore, parameter correcti on can only be done when IR236 is running after half an hour. blackbody measurement take the whole envi ronment condition into consideration, for blackbody shall be located in front of IR236 camera, and measurement results are stable after the blackbody is switched on after t en minutes. meanwhile if the location of blackbody is changed, the operator needs to reset the blackbody area in the software. 42
IR236 infrared fever sensing system 4.2 temperature measurement parameter setting the first temperature parameter setting of advanced setting is ?1# thermal video?, as shown in figure 2-2: measurement coefficient: parameters for te mperature measurement, can only be set by technicians for temperature measurement. brightness and contrast: thermal video br ightness and contrast parameter setting. display brightness and contrast: brightness and c ontrast of thermal video of monitoring center temperature correction: difference of body temperature value and body surface temperature measured by IR236. this differ ence shall be changed according to different environment temperature. body temperature values getting from clinical thermometer minus the temperature values getting from IR236 equals this correction coefficient. the higher of temperature correction value, t he higher of measured temperature value. hardware control: adjustment of thermal video detector, such as shutter compensation, near focus, far focus, brightness and contrast. blackbody: using blackbody wi th constant temperature to measure body temperature. note operator can make change when needed. 43
IR236 infrared fever sensing system 4.3 temperature measurement parameter using help ?coefficient k_f? of measurement paramete r is set before delivery and needn?t to be changed. in accordance with shutter and blackbody measurement, only correction coefficient 1 and body inner and surface temperature difference (manual) need to be changed. after correction of temperature measurement c oefficient of IR236, the temperature values measured is body surface te mperature. there is a di fference between people?s body temperature and surface temperature. in order to get a real body temperature, it is necessary to add this difference ont o the surface temperature. actually body surface temperature value va ries according to different environment, therefore the difference between body inner and surface temper ature varies as the same. wuhan guide has summarized body inner and surface temperature difference mathematical model in different envir onments through a large number of body temperature measurement test. IR236 system can automatically count real-time body inner and surface temperature difference in accordance with this mathematical model. correction coefficient 1: effective in shutter measurement mode. the measured value will decrease one degree when this parameter increase by 1000, vise versa. automatic body inner and surface temperature difference: when the parameter is selected, this value will be added automatically in the temperature va lues. if it is not selected, this value will not give any effect on the final temperature measurement value. this value is effective in both s hutter and blackbody measurement mode. body inner and surface temperature difference (manual): when automatic body inner and surface temperature differenc e has deviation with specific situation, this parameter needs to be adjusted manually. this parameter shall be zero in normal condition. increase this parameter by one, the values shown on screen will increase by one. decrease this parameter by one, the values shown on screen will decrease by one. this parameter can be positive number, negative number and decimal fraction and is effective both in shutter and blackbody measurement mode. blackbody: before adopting blackbody measurement mode, please locate blackbody area in the software and input the blackbody ?s constant temperature value in the parameter ?blackbody measurement?. 44
IR236 infrared fever sensing system 4.4 shutter measurement mode 4.4.1 shutter measurement mode---correcti on of measurement coefficient (only for k-f coefficient and correction coefficient 1) the operation schedules are as follows: 1) cancel ?automatic body inner and surfac e temperature difference? in the software 2) power on IR236 3) put two blackbody in front of IR236, which is 6~8 meters away. adjust the blackbody?s temperatures to be 39.0 and 30.0 4) leave IR236 and blackbody for about half an hour until both of them in a stable working condition.. 5) set the system measuring range to be 33.0 42.0 , so that the two blackbody can be detected by IR236. 6) adjust k_f and correction coefficient 1 in ?advanced setting? dialog box, make the blackbody temperature on the images same with the actual temper atures of the two blackbody. notice: k_f and correction coefficient 1 has already been adjusted before delivery, please do not change the two coeffi cient in general condition. the temperature principle is measure the bod y surface temperature, add the temperature difference between body inner and surfac e temperature and get the final body temperature. the alarm function is to adjust whether the target te mperature is between 37.5 to 40 . difference between body inner and surface temperature can be divided into two different parameters: auto body inner and surface temperature difference manual body inner and surface temperature difference auto body inner and surface temperature diff erence is the temperature correction under current environment temperature which is only valid only when the setting has been chosen in the software. manual body inner and surface temperature differ ence is valid all the time. this parameter can be used manually when auto mode has deviation. the m anual body inner and surface temperature difference can be set as 0. 45
IR236 infrared fever sensing system 46 the temperature measurement formulas are as follows: 1 when auto body inner and surface temperat ure difference parameter is selected body temperature=body surface temperatur e + auto body inner and surface temperature difference + manual body inner and surface temperature difference 2 when auto body inner and surface temperat ure difference parameter isn?t selected body temperature=body surface tem perature + manual body inner and surface temperature difference
IR236 infrared fever sensing system 4.4.2 blackbody measurement mode--- correction of measurement coefficient (only adjust manual body inner and surface difference ) 1) select auto body inner and surface temper ature difference in 1# infrared video of advanced setting dialog box. 2) set blackbody area in the software same as the actual infrared image from ?alarm setting? 3) input actual blackbody tem perature in 1# infrared video. en sure that the blackbody is switched on for half an hour. 4) set manual body inner and surfac e temperature difference as 0 5) press f5 to view passenger?s forehead and adjust manual body inner and surface temperature difference: press f5 when return to the main monitoring surface, the highest temperature value will be shown on the screen. observe the general hi ghest temperature value of crowds. for example, if the general temper ature value of forehead is 34.5 which is less than the normal forehead temperature (36 ), enter into the infrared video parameter. if the manual temperature difference is 1, t hen the operator shall change this value into 2.5 (plus 1.5 on the former value 1). if the forehead temperatur e of crowds shown on the screen is , then the difference shall be changed from 1 to 0. 47
IR236 infrared fever sensing system 4.4.3 combination and test of two temperature measurement modes press f3 to switch between blackbody measurment mode and s hutter measurement mode. before using both the two modes, pleas e correct the parameter of blackbody and shutter measurement and detect the same target when swit ching between the two modes. if there is no big difference, that m eans the system is working well. summarize: keep blackbody and IR236 powering on for more than half an hour to make them in a stable working condition select auto body inner and su rface temperature difference adjust focus (far and near) to make the blackbody shown clearly in infrared image ensure that the blackbody area setting is co rrect and the input blackbody temperature is 33 adopt blackbody measurement mode. when manual body in ner and surface temperature value is 0, press f5 to see whether people?s forehead temperature is nearly 36 . in general condition, manual temperature diff erence 0 is able to measure temperature accurately. when auto temperature differ ence has difference wi th actual body?s temperature, change the manual temperatur e difference to make mass passenger?s forehead temperature to be 36 . after adjusting blackbody measurement m ode, keep the same manual temperature difference and select auto temperature differ ence, switch to shu tter measurement mode. (deselect black body measurement) review people?s forehead temperature. if the value is 1 less than 36 , add 1000 on correction coefficient 1;if the value is 1 more than 36 , minus 1000 on correction coefficient. notice: if the system doesn?t get correct temperature measurem ent, before changing the coefficient, please check whether the black body works well or whether the detector?s location has been changed. 48
