Embodiment

With reference to Fig. 1, the utility model automatic ticket checker height detector, be located in two gates of paired setting, comprise the electric transducer 100 that diffuses for detection of passenger's height in the gate passage, the described electric transducer 100 that diffuses is connected with signal collection and the processing unit 200 of a collection and processes sensor signal, and described signal collection and processing unit 200 also are connected with the control module 300 of a control automatic ticket checker duty.

The described electric transducer 100 that diffuses comprises light source, light activated element and detecting unit, after the light that described light source sends shines and detects on the thing, with arbitrarily angled scattering, light activated element detects that detected cell translation is the high-low level signal behind the light that reflects, described high-low level signal is converted to digital signal through signal collection and processing unit 200, preferably, in the utility model, described signal collection and processing unit 200 are programmable logic controller (PLC) (Programmable Logic Controller, PLC), PLC adopts a class programmable memory, be used for its internally stored program, the actuating logic computing, sequential control, regularly, the user oriented instructions such as counting and arithmetical operation, and by numeral or analog pattern input/output various types of machineries of control or production run.Described control module 300 is industrial computer, and PLC is connected to industrial computer by serial ports.

With reference to Fig. 2, in a preferred embodiment, described height detector comprises two for detection of the electric transducer 100 that diffuses of passenger's height in the gate passage, the described electric transducer 100 of diffusing is paired is distributed in two gate opposite side upper end positions (as shown in Figure 2), the setting angle of electric transducer 100 of diffusing is to install obliquely, and the effective sensing range of passenger's height is the common factor of the valid analysing range of above-mentioned two electric transducers 100 that diffuse.Preferably, diffuse height and the setting angle of electric transducer 100 can be regulated.

With reference to Fig. 3, suppose that two distances between gate are L, the two electric transducer 100 residing height that diffuse are H, lay respectively at position A shown in Figure 3 and position B, the electric transducer 100 of diffusing is upper the installation tiltedly, with the angle of horizontal direction be α, the minimum boundary line that electric transducer can detect that diffuses, position A place is ED, the minimum boundary line that electric transducer can detect that diffuses, B place, position is EC, supposes that the maximal value of the minimum height values that the above-mentioned electric transducer 100 that diffuses can detect jointly is d _Max, can be d with the minimum value of the minimum height values that detects _Min

When the passenger walked near the gate edge, the minimum height values that detect this moment was maximal value d _Max, computing formula is as follows:
