Abstract
The utility model relates to an intelligent fare-evasion-preventing real-time detection system for a subway. The system comprises a pressure sensor, human body pyroelectricity infrared ray sensors, a detection circuit and an alarm, wherein the human body pyroelectricity infrared ray sensors are mounted at the sides, where people pass by, of the side surfaces of subway turnstiles; four areas are divided in the direction where people enter the turnstiles, the first area is a turnstile-entering card swiping area, the second area is a turnstile door passing area, the third area is a turnstile door leaving area and the fourth area is a turnstile leaving area; infrared sensors are mounted in each area, and the pressure sensor is correspondingly mounted on the ground in the turnstile-entering card swiping area in the first area. Whether two passengers simultaneously pass by a turnstile to evade fare is judged by the detection circuit through infrared ray detection of the four areas and pressure detection of the first area, so that automatic detection is realized, and a large quantity of manpower and material resources is saved. In order to effectively inhibit the ticket evading behavior, the system introduces the alarming subsystem, and a fare evader can be warned on the scene.
Description
Technical field
The utility model relates to a kind of detection system, particularly the anti-real-time detecting system of stealing a ride of a kind of subway intelligence.
Background technology
The progressively quickening of social and economic fast development and urbanization process, cause city size to expand gradually, urban population also sharply increases, the thing followed is a series of problems such as traffic congestion, in order to overcome these difficulties, to strengthen Transport Facility Construction on the one hand, need on the other hand more ticket-check equipment---gate.But to consume a large amount of human costs staff of each gate arrangement.Meanwhile, only in the middle of the underground railway track traffic on one ground, Shanghai, average daily ten thousand people steal a ride, and lose every year more than 1,000 ten thousand yuans, so the research of the anti-real-time detecting system of stealing a ride of subway intelligence is had to important social effect and economic implications.
The AFC system being applied at present in society does not generally possess automatic identification function, retrain passengers' the behavior of stealing a ride by morals, even if staff finds to steal a ride passenger, can only go forward to prevent and but not punish right, the visitor that steals a ride is taken advantage of and do not frighten effect.

Embodiment
Fig. 1 is the pressure transducer location map of the embodiment of the present invention, diagram region can real-time perception through the pressure of region object.As shown in Figure 2, pressure perceptron output voltage and pressure are to present the linear output relation of 1～5V.Voltage comparator in the testing circuit structure square frame of embodiment as shown in Figure 4, the primary element comprising for voltage comparator has, and sets up the voltage reference of stable threshold
, dwindle input voltage

r 2, a comparer.Work as input voltage
vmeet
, comparer triggers, output terminal output high level.By suitable threshold value is set, can select the minimum pressure values of trigger voltage comparer output high level.Thereby can effectively detect the free of charge children passenger that body weight is less.
Fig. 3 is the human body pyroelectricity infrared ray sensor location map of the embodiment of the present invention, people enters gate direction and is divided into 4 districts, enter the gate district 1 that swipes the card, by gate Shan Men district 2, leave gate Shan Men district 3, leave gate district 4, difference is corresponding 1～No. 4 human body pyroelectricity infrared ray sensor as shown in Figure 3, 5～No. 8 human body pyroelectricity infrared ray sensors, 9～No. 10 human body pyroelectricity infrared ray sensors, 11～No. 12 human body pyroelectricity infrared ray sensors, human body has constant body temperature, generally at 37 degree, so can send the infrared ray of specific wavelength 10UM left and right, passive type infrared probe by survey human-body emitting about 10UM infrared ray and carry out work, this element will lose charge balance receiving when human infrared radiation temperature changes, outwards discharge electric charge, subsequent conditioning circuit just can produce alerting signal after processing after testing.As shown in Figure 3, in the time that 5～No. 8 human body pyroelectricity infrared ray sensors detect that passenger fans door by gate, 1～No. 4 human body pyroelectricity infrared ray sensor detects that passenger passes through simultaneously, and the force value that pressure search coverage detects is greater than set threshold value.Now can judge and exist tail to act part.The work of now logical and module output high level trigger alarm device.
Fig. 4 is the testing circuit block diagram of embodiment, and 1～No. 4 human body pyroelectricity infrared sensor output signal is connected to logical and module through logical OR module; The output signal of 5～No. 8 human body pyroelectricity infrared ray sensors is exported a road and is connected to the logical and module on 1～No. 4 human body pyroelectricity infrared sensor one tunnel through logical OR module, another road is connected to the S end of SR latch.Pressure transducer output signal converts low and high level signal to through over-voltage comparator and also receives the logical and module on 1～No. 4 human body pyroelectricity infrared sensor one tunnel.1～No. 4 human body pyroelectricity infrared ray sensor is for detection of the current state of passenger in region one, and pressure transducer is for detection of passenger's body weight size in region one.In the time having passenger through the fan door region at 5～No. 8 human body pyroelectricity infrared ray sensor places, if 1～No. 4 human body pyroelectricity infrared ray sensor detects that human body passes through, and meet passenger's body weight and be greater than set threshold value, now meet the capable event of stealing a ride of tail, 1～No. 4 sensor, 5～No. 8 sensors, pressure transducer duty is 1 simultaneously, the logical and module that it connects is output as 1, thus the work of trigger alarm device.9～No. 10 human body pyroelectricity infrared ray sensors are received the R end of SR latch by logical OR module.In the time of S=R=0, output terminal Q state remains unchanged.When under the condition of R=0, in the time that logical one level appears in S end, circuit is converted to rapidly Q=1 state.When under the condition of S=0, in the time that logical zero level appears in R end, circuit is converted to rapidly Q=0 state.In the time that passenger normally fans door region two by gate passage, 5～No. 8 infrared ray sensor detects right of way signal, is also S=1, and R=0 is Q=1 now, and passenger leaves region two, now S=0, R=0.The output of Q end keeps high level.In the time that passenger enters region three, 9～No. 10 human body pyroelectricity infrared ray sensor detects right of way signal, is also S=0, R=1 is Q=0 now, now Q=0, there is negative edge in circuit, negative edge testing circuit detects that when negative edge occurs, output terminal is converted to low level by high level.In the time that passenger attempts crossing over fan door and steals a ride, 5～No. 8 human body pyroelectricity infrared ray sensor can not detect any signal, in the time that passenger enters region three, 9～No. 10 human body pyroelectricity infrared ray sensor detects right of way signal, also be S=0, R=1 is Q=0 now, now Q=0, there is not negative edge in circuit, so negative edge testing circuit output terminal keeps high level always.
Table 1 is the negative edge testing circuit truth table of embodiment.
