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.The wireless node network signal means with the 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 that the passenger flow counter wireless signal distributes, and the camber line around wireless network node 7 is that the wireless network node wireless signal distributes.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 device 5 and the ID of wireless network node 7, wireless location label 6 can be distinguished the signal intensity in unlike signal source.When wireless location label 6 moves to reposition 9 along the direction of arrow in Fig. 3, (with the black empty circles, mean), 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 passenger flow counting system of the present embodiment, wireless location label 6 height of living in remains unchanged substantially, therefore wireless location label 6 receives the wireless signal strength variation only as the horizontal level change process, for the variation of vertical direction, ignores.
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 zone of passenger flow counting, the personnel (salesman) without counting of (chain store) wear the wireless location label, movable in the zone of passenger flow counting without personnel and the passenger flow personnel of counting;
Step 2: the wireless location label receives the wireless signal of wireless network node and the wireless signal of passenger flow counting device in real time, and the wireless signal strength of identification wireless network node and the wireless signal strength of passenger flow counting device;
As shown in Figure 6, on the wireless location label, after electric-opening, the Automatic-searching wireless network is also verified node (wireless network node and passenger flow counting device) signal, and at first decision node ID, from all wireless networks that search, only sampled to register node.Obtain each node signal intensity data at synchronization.If there is the passenger flow counting device, the wireless location label will sample to such an extent that signal strength data is uploaded to the passenger flow counting device and carries out strength ratio.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 periodically, for example every 200 milliseconds once, frequency more high precision is larger, but corresponding power consumption is also just more, specifically can set flexibly according to practical application.
Step 3: the passenger flow counting device carries out passenger flow counting to the zone of passenger flow counting in real time;
The flow process that the passenger flow counting device carries out passenger flow counting to the zone of passenger flow counting in real time as shown in Figure 5, has at first judged whether that wireless positioning label is online, if do not have, carries out normal passenger flow counting work; If there is wireless positioning label online, start 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, the number that arranges is rejected zone bit, and records time of origin.When a timeslice (for the video passenger flow counter, refers to one-frame video data; For infrared passenger flow counter, refer to an infra-red detection) passenger flow counting finish dealing with after, system automatic decision number is rejected zone bit, if this zone bit is put, explanation has wireless positioning label carrier pass in and out shop and be counted, in the number record, the corresponding data of corresponding time point is rejected, complete this circulation.If system is not carried out end, return to beginning and circulate next time, until finish.
Step 4: the passenger flow counting device periodically receives the wireless signal strength of the wireless network node that this wireless location label sends and the wireless signal strength of passenger flow counting device;
Step 5: relatively the wireless signal strength variation of current time and upper a wireless network node that the wireless location label receives constantly and the wireless signal strength of passenger flow counting device change;
Fig. 4 is clerking activities path and the contrast of reference point change in signal strength of carrying a certain wireless location label in the present embodiment.In figure, every a line represents different crawler behaviors, for example the first row representative " entering " behavior, and the implementation process of the behavior is meaned by two empty circles.In figure, the empty circles outside shop means the initial position of wireless location label, means movable route and the direction of wireless location label with dotted arrow, the wireless location label position when empty circles in shop means " entering " behavior end.Whole process is by starting outside shop, by the shop entrance, enters in rear arrival shop and finishes.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 respectively " leaving ", " mobile 1 ", " mobile 2 ", " hovering 1 ", " hovering 2 " behavior.Mobile behavior and Wander behavior have two kinds, and respectively corresponding different activity direction, distinguish with the direction of arrow.
The one row figure of central authorities in Fig. 4 and right side one row figure are respectively the wireless signal strength temporal evolution figure 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 the intensity time changing curves.As can be seen from the figure, when wireless location label manner is " entering ", the signal intensity of wireless network node is ascendant trend gradually, and the wireless signal strength of passenger flow counting device is the first shape of a hoof trend of rising, rear decline.And signal intensity that it should be noted that wireless network node is zero-based, this process with wireless location label perception indoor wireless networks node signal is corresponding.
The second row in Fig. 4 " leaves " in behavior, and the wireless location label is gone to shop in shop, and the signal intensity of corresponding 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, be horseshoe-shape.
In the third line in Fig. 4 " mobile 1 " behavior, the wireless location label moves in Nei Xiang exit, 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 increases trend gradually, and this horseshoe-shape when " leaving " behavior is distributed with a great difference.
In fourth line in Fig. 4 " mobile 2 " behavior, the wireless location label moves to deviate from Way out in shop, because of the wireless location label in shop, therefore 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 descending 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 is that corresponding wireless network node and passenger flow counting device have occurred that respectively the contrary horse-hof shape of both direction distributes, these distribute from other kinds all have significantly different.
From above-mentioned signal intensity temporal evolution distribution plan, can distinguish wireless location label carrier some specific activities in shop, more particularly than the behavior that is easier to obscure.Therefore, in certain concrete application, chain store for example, having worn the activity of salesman in shop of wireless location label can be distinguished with client, be that passenger flow counting system of the present invention has possessed personnel and distinguishes function, more specifically, when the passenger flow counting device produces a counting operation, be that can to distinguish the people who triggers this counting behavior be salesman or client.Further, can also be classified and be gathered each salesman's behavior, for example can add up that Lee salesman passes in and out the shop number of times some day, amounts in the shop time, the departure time amounts to, usually when check out, hover number of times and time etc. in shop.These provide immediate data to support for standard salesman behavior, formulation corresponding management system.
Step 6: the wireless signal strength variation of the wireless network node received according to the wireless location label and the wireless signal strength of passenger flow counting device change the behavior of the personnel to carrying the wireless location label and are classified:
If the wireless signal strength of the wireless network node that the 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, and the behavior of carrying the personnel of this wireless location label is to enter in the zone of passenger flow counting;
If the wireless signal strength of the wireless network node that the 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, and the behavior of carrying the personnel of this wireless location label is to leave in the zone of passenger flow counting;
If the wireless signal strength of the wireless network node that the wireless location label receives dies down gradually, and the wireless signal strength of passenger flow counting device grow gradually, the behavior of carrying the personnel of this wireless location label is mobile to the zone, doorway;
If the wireless signal strength of the wireless network node that the wireless location label receives is grow gradually, and the wireless signal strength of passenger flow counting device dies down gradually, and the behavior of carrying the personnel of this wireless location label is that the opposite direction to the zone, doorway moves;
The rear grow if the wireless signal strength of the wireless network node that the wireless location label receives first dies down, and after the first grow of the wireless signal strength of passenger flow counting device, die down, the behavior of carrying the personnel of this wireless location label is then to return again to the zone, doorway is mobile;
If die down after the first grow of the wireless signal strength of the wireless network node that the wireless location label receives, and the wireless signal strength of the passenger flow counting device rear grow that first dies down, the behavior of carrying the personnel of this wireless location label is then to return again to the opposite direction in zone, doorway is mobile;
Step 7: time, scope of activities and the frequent activity degree of personnel in the zone of passenger flow counting that can carry the wireless location label according to the statistic of classification of the personnel's that carry the wireless location label behavior;
Step 8: judge the personnel that the wireless location label whether occurs carrying in the zone of passenger flow counting: be that the personnel that the wireless location label is carried in the zone of the passenger flow counting that will enter or leave reject from passenger flow counting; No, return to step 3.
Identical with embodiment 1, the passenger flow counting system that personnel distinguish function that has based on wireless network of the present invention is applied in real chain store as shown in Figure 1.
