Fig. 3 is the wireless network signal schematic diagram that wireless location label 6 receives wireless network node 7 and passenger flow counting device 5.Wireless node network signal represents with arc dotted line in the drawings, and camber line is closeer shows that signal is stronger, and the camber line around passenger flow counting device 5 is the distribution of passenger flow counter wireless signal, and the camber line around wireless network node 7 is the distribution of wireless network node wireless signal.Wireless location label 6 receives the wireless network signal of passenger flow counting device 5 and wireless network node 7 simultaneously.By the ID of passenger flow counting the device 5 and ID of wireless network node 7, wireless location label 6 can distinguish the signal intensity in unlike signal source.When wireless location label 6 moves to reposition 9 along the direction of arrow in Fig. 3 (representing with black empty circles), its wireless signal strength received changes.Especially, the signal intensity that passenger flow counting device 5 sends reduces, and the signal intensity that wireless network node 7 sends increases.
In the normal use procedure of the passenger flow counting system of the present embodiment, highly substantially, remain unchanged residing for wireless location label 6, therefore wireless location label 6 receives wireless signal strength change only as horizontal level change process, and the change for vertical direction is ignored.
Adopt above-mentioned system to carry out the method for passenger flow counting, its flow process as shown in Figure 10, comprises the following steps:
Step 1: in the region of passenger flow counting, the personnel (salesman) without the need to counting of (chain store) wear wireless location label, without the need to personnel and passenger flow personnel activity in the region of passenger flow counting of counting;
Step 2: the wireless signal of wireless location label real-time reception wireless network node and the wireless signal of passenger flow counting device, and identify the wireless signal strength of wireless network node and the wireless signal strength of passenger flow counting device;
As shown in Figure 6, on wireless location label after electric-opening, Automatic-searching wireless network also verifies node (wireless network node and passenger flow counting device) signal, first decision node ID, from all wireless networks searched, only register node is sampled.Each node signal strength data are obtained at synchronization.If there is passenger flow counting device, wireless location label will sample signal strength data is uploaded to passenger flow counting device and carries out strength ratio comparatively.After completing a circulation, continue to obtain each node wireless network data and start next circulation until label is closed.The beginning of each circulation can be periodic, such as every 200 milliseconds once, frequency more high precision is larger, but the power consumption of correspondence is also more, specifically can set flexibly according to practical application.
Step 3: passenger flow counting device carries out passenger flow counting to the region of passenger flow counting in real time;
Passenger flow counting device carries out the flow process of passenger flow counting as shown in Figure 5 to the region of passenger flow counting in real time, has first judged whether that wireless positioning label is online, if do not had, has then performed normal passenger flow counting work; If there is wireless positioning label online, then starts to receive the signal strength data that each wireless location label sends over, then perform step 4, judge wireless location label-carrier's Activity Type and time of origin.If wireless location label-carrier crawler behavior meets the behavior of " entering " or " leaving " type, then the number that arranges rejects zone bit, and records time of origin.When a timeslice (for video passenger flow counter, refers to one-frame video data; For infrared passenger flow counter, refer to an infra-red detection) passenger flow counting process complete after, system automatic decision number rejects zone bit, if this zone bit is put, then illustrating has wireless positioning label carrier pass in and out shop and be counted, in number record, the corresponding data of corresponding time point is rejected, complete this circulation.If system does not perform end, return beginning and circulate next time, until terminate.
Step 4: the wireless signal strength of wireless network node that this wireless location label of passenger flow counting device periodic receipt sends and the wireless signal strength of passenger flow counting device;
Step 5: the wireless signal strength of the wireless signal strength change and passenger flow counting device of comparing the wireless network node that current time and a upper moment wireless location label receive changes;
Fig. 4 carries the clerking activities path of a certain wireless location label and reference point change in signal strength contrasts in the present embodiment.In figure, every a line represents different crawler behavior, such as the first row representative " entering " behavior, and the implementation process of the behavior is represented by two empty circles.In figure, the empty circles outside shop represents the initial position of wireless location label, and band dotted arrow represents movable route and the direction of wireless location label, the wireless location label position at the end of behavior that the empty circles in shop represents " entering ".Whole process is by outside shop, is entered in rear arrival shop terminate by store entrances.Clearly, this activity is the process that wireless location label-carrier enters shop.In like manner, second of Fig. 4 to walk to the 6th row be " leaving ", " mobile 1 ", " mobile 2 ", " hovering 1 ", " hovering 2 " behavior respectively.Mobile behavior and Wander behavior have two kinds, correspond to different activity directions respectively, distinguish with the direction of arrow.
Central authorities one row figure in Fig. 4 and right side one row figure is respectively the wireless signal strength variation diagram in time of the corresponding wireless network node of wireless location label and passenger flow counting device.In figure, horizontal ordinate is the time, and ordinate is wireless signal strength, and figure cathetus or curve are intensity time changing curves.As can be seen from the figure, when wireless location tag activity mode is for " entering ", the signal intensity of wireless network node in ascendant trend gradually, and the wireless signal strength of passenger flow counting device in first rising, the shape of a hoof trend of rear decline.And it should be noted that the signal intensity of wireless network node is zero-based, this is corresponding with the process of wireless location label perception indoor wireless networks node signal.
The second row in Fig. 4 " leaves " in behavior, and wireless location label is gone to shop in shop, and the signal intensity that correspond to wireless network node is reduced to zero point gradually from a large value.And the signal intensity of passenger flow counting device first increases, rear minimizing, in horseshoe-shape.
In the third line " mobile 1 " behavior in Fig. 4, wireless location label moves to exit in shop, but does not really leave.Corresponding wireless network node signal intensity is on a declining curve, but is not reduced to zero point.More significantly, passenger flow counting device signal intensity is in increasing trend gradually, and horseshoe-shape when this and " leaving " behavior is distributed with a great difference.
In fourth line " mobile 2 " behavior in Fig. 4, wireless location label moves to deviate from Way out in shop, because wireless location label is in shop, therefore does not form " entering " behavior.Corresponding wireless network node signal presents increases trend gradually, but initial value is not zero.More importantly, passenger flow counting device signal intensity tendency, for decline gradually, is distributed with a great difference with the horse-hof shape of " entering " behavior.
Fifth line in Fig. 4 " hovers 1 " and the behavior of " hovering 2 " of the 6th row is the third line behavior and the combining of fourth line behavior in fact, and just the order of associating is different.Result be corresponding wireless network node and passenger flow counting device occurred respectively both direction contrary horse-hof shape distribution, these distribution from other kinds all have significantly different.
From above-mentioned signal intensity in time change profile figure, wireless location label-carrier some specific activities in shop can be distinguished, more particularly than the behavior being easier to obscure.Therefore, in certain embody rule, such as chain store, the activity of salesman in shop of having worn wireless location label can be distinguished with client, namely passenger flow counting system of the present invention has possessed personnel and has distinguished function, more specifically, when passenger flow counting device produces a counting operation, be to distinguish that to trigger the people of this counting behavior be salesman or client.Further, can also classify to the behavior of each salesman and gather, such as can add up Lee salesman pass in and out some day shop number of times, the shop time amount to, the departure time amounts to, usually when checks out, hover in shop number of times and time etc.These are specification salesman behavior, formulation corresponding management system provides immediate data to support.
Step 6: the wireless signal strength change of wireless network node received according to wireless location label and the wireless signal strength change of passenger flow counting device are classified to the behavior of the personnel carrying wireless location label:
If the wireless signal strength of the wireless network node that wireless location label receives is from zero grow gradually, and the first grow of the wireless signal strength of passenger flow counting device dies down again, then the behavior of carrying the personnel of this wireless location label enters in the region of passenger flow counting;
If the wireless signal strength of the wireless network node that wireless location label receives dies down gradually to zero, and the first grow of the wireless signal strength of passenger flow counting device dies down again, then the behavior of carrying the personnel of this wireless location label leaves in the region of passenger flow counting;
If the wireless signal strength of the wireless network node that wireless location label receives dies down gradually, and the wireless signal strength of passenger flow counting device grow gradually, then the behavior of carrying the personnel of this wireless location label is moved to region, doorway;
If the wireless signal strength grow gradually of wireless network node that wireless location label receives, and the wireless signal strength of passenger flow counting device dies down gradually, then the behavior of carrying the personnel of this wireless location label is moved to the opposite direction in region, doorway;
Grow after if the wireless signal strength of the wireless network node that wireless location label receives first dies down, and die down after the first grow of the wireless signal strength of passenger flow counting device, then the behavior of carrying the personnel of this wireless location label moves to region, doorway then to return again;
If die down after the first grow of the wireless signal strength of the wireless network node that wireless location label receives, and the wireless signal strength of passenger flow counting device first die down after grow, then the behavior of carrying the personnel of this wireless location label then returns again to the opposite direction in region, doorway is mobile;
Step 7: the time of personnel in the region of passenger flow counting of wireless location label, scope of activities and frequent activity degree can be carried according to the statistic of classification of behavior of the personnel carrying wireless location label;
Step 8: the personnel whether occurring carrying wireless location label in the region judging passenger flow counting: be that the personnel then region of the passenger flow counting entering or leave being carried wireless location label reject from passenger flow counting; No, then return step 3.
