Hereinafter, an example of an embodiment of a people counting system according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a first embodiment of a people counting system according to the present invention. In the figure, the number counting system of this example comprises counting means 101, a portable terminal 301, and data counting means 401, and is for calculating the number of persons in a specific area (described later).

  The counting unit 101 includes a control unit 102, a television camera 103, a calculation unit 104, a communication unit 105, a data holding unit 106, and a timing unit 107. The calculation unit 104, the communication unit 105, the data holding means 106, and the time measuring means 107 are electrically connected to the control means 102 via the data bus 108 and controlled.

  The counting means 101 having such a configuration is installed in a place where people pass, and the image of the television camera 103 is imaged by the calculation means 104 to count the number of passing persons in the screen. The data is held in the data holding means 106 together with the time measured in step.

  The counting point where the counting means 101 is installed and the number of passing people is counted is a place where a person passes, more specifically, a passing place where the specific area is entered and exited, All the traffic places necessary for calculating the number of persons in the specific area.

  The control unit 102 receives a command from the system administrator via the communication unit 105, controls the start, stop, or initialization of the calculation unit 104, and is further held in the data holding unit 106. The number data relating to the number of passing persons is transmitted to the portable terminal 301 via the communication means 105, or the contents of the number of persons data are initialized. In addition, the control unit 102 adjusts the time of the time measuring unit 107 to the time of the time measuring unit (described later) of the portable terminal 301.

  More specifically, the counting means 101 counts the number of passing persons in each passing direction per unit time at the counting point. This will be specifically described with reference to FIG.

  FIG. 2 is a diagram for explaining an example of counting the number of passing people by the counting means 101. For example, as shown in FIG. 2A, when viewed from above the passer-by 200, if there are two areas of the passer-by 200, A and B, the counting means 101 The number of people passing from A to B and the number of people passing from B to A are counted, and the number of people passing in each direction is stored in the data holding means 106 as number data. Further, for example, when the counting means 101 is installed at a place such as the center of a crossroad, the areas that the passer-by 200 can pass are areas C and D, as shown in FIG. It can be divided into E, F, and G. For example, the number of people who passed from F through G to D, and the opposite, the number of people who passed from D through G to F, or from E through G to F The number of people passing in each direction, such as the number of people who pass, is held in the data holding means 106 as number of people data. In addition, the number of people staying in G for a predetermined period or more can be counted and held.

  The number data held in the data holding means 106 is held as holding data together with the time measured by the time measuring means 107.

  Such a traffic direction is set in the calculation means 104 by the control means 102 in response to the setting result set in the portable terminal 301 (described in detail later).

  Next, the portable terminal 301 will be described with reference to FIG. FIG. 3 is a diagram illustrating a configuration of the mobile terminal 301. In the figure, the portable terminal 301 includes a control unit 303 that can be operated via a man-machine interface 302, and further includes a command transmission unit 304, a display unit 305, a time measuring unit 306, a data receiving unit 307, and a data holding unit 308. And a data transmission means 309. The command transmission unit 304, the display unit 305, the timing unit 306, the data reception unit 307, the data holding unit 308, and the data transmission unit 309 are connected to the control unit 303 via the data bus 310 and controlled. It is like that.

  The mobile terminal 301 having such a configuration initializes the counting unit 101, operates start / stop of the counting operation of the number of passing persons, or is held in the data holding unit 106 in a place where the communication unit 105 can communicate. A command for requesting transmission of the number data is created and transmitted to the counting means 101. The system administrator creates the command using the man-machine interface 302 and the control unit 303 and transmits the command to the communication unit 105 via the command transmission unit 304. The data receiving means 307 receives the requested number data via the communication means 105 and holds it in the data holding means 308. At this time, the portable terminal 301 receives the number data together with the identification code of the counting means 101 and the time (time at transmission / reception) measured by the time counting means 107 at the time of data transmission / reception.

Based on the identification code, the display means 305 clearly indicates that the data of the counting means 101 corresponds to the identification code, and the data holding means together with the number data (that is, the number of persons in each direction of travel) and the number data. The timekeeping time stored in 106 is displayed on the display means 305. However, if there is a difference between the time measured at the time of data transmission / reception (time of transmission / reception) by the time measuring means 306 and the time of transmission / reception by the time measuring means 107, the time keeping stored in the data holding means 106 by this difference. The time is corrected, and the corrected time is displayed on the display means 305.
As a correction method, for example, the following formula is used.
(Corrected timing time) = (time keeping time held in the data holding means 106) + (PQ)
P: Transmission / reception time measured by the time measuring means 306
Q: Transmission / reception time measured by the time measuring means 107 That is, as shown in the above formula, the result of subtracting the transmission / reception time measured by the time measuring means 107 from the transmission / reception time measured by the time measuring means 306 is the data What is necessary is just to add to the time-measurement time stored in the holding means 106. As described above, by correcting the time counting time, the number of passing persons can be managed based on the time counting time of the mobile terminal 301 even when the time counting times of the counting unit 101 and the mobile terminal 301 do not match. It has become.

  The data holding unit 308 secures a recording area for each counting unit 101 based on the identification code, and holds the time count or the corrected timing time of the corresponding counting unit 101 and the number of people data in the corresponding place. Is supposed to hold as. As described above, by holding the holding data by dividing the area according to the identification code, the number of people data of the plurality of counting means 101 can be held.

  Communication of commands, data, and the like between the portable terminal 301 and the counting unit 101 may be performed by wireless communication such as radio wave communication and infrared communication, and the portable terminal 301 and the counting unit 101 are connected with a cable with a connector. You may connect and communicate.

  The data transmission unit 309 transmits the data held in the data holding unit 308 to the data totaling unit 401.

  Next, the data totaling unit 401 will be described. FIG. 4 is a diagram showing a configuration of the data totaling unit 401. The data totaling means 401 constitutes a calculating means for receiving the number data from the portable terminal 301 and calculating the number of persons in a specific area from the number data using a predetermined calculation method.

  The configuration of the data totaling unit 401 will be specifically described. The data totaling unit 401 includes a control unit 403 that can be operated by a man-machine interface 402, and further includes an output unit 404, a time measuring unit 405, a data receiving unit 406, , Counting means arrangement drawing holding means 407, data creation holding means 408, and display means 409. The output unit 404, the time measuring unit 405, the data receiving unit 406, the counting unit arrangement drawing holding unit 407, the data creation holding unit 408, and the display unit 409 are connected to the control unit 403 by the data bus 410 and controlled. It is like that. Hereinafter, each of these configurations will be described.

The time counting means 405 keeps counting the reference time of the data counting means 401. The data receiving unit 406 receives the number of people data held by the portable terminal 301 through the data transmission unit 309 together with the corrected time count. At this time, the clock time (transmission / reception time) at the time of transmission / reception of the clock means 306 is also received. The data creation / holding means 408 holds the held data every time the held data (number of people data and time count) is received from the portable terminal 301. However, if there is a difference between the time measured by the time measuring means 405 at the time of transmission / reception (transmission / reception time) and the time measured by the time measuring means 306 (time of transmission / reception), the difference between the time and the number data The received corrected time (corrected time stored in the data holding means 308) is corrected, and the corrected time is stored together with the number data.
As a correction method, for example, the following formula is used.
(Recorrected timing time) = (corrected timing time held in the data holding means 308) + (RS)
R: Transmission / reception time measured by the time measuring means 405
S: Transmission / reception time measured by the timing unit 306 As shown in the above equation, the transmission / reception time measured by the timing unit 306 is subtracted from the transmission / reception time measured by the timing unit 405 as data. What is necessary is just to add to the corrected time keeping time hold | maintained at the holding means 308. In this way, by correcting the corrected timing time held in the data holding means 308 at the time of sending and receiving the number of people data, even if the timing times of the portable terminal 301 and the data counting means 401 do not match, The number of passersby can be managed on the basis of the time measured by the data counting means 401.

  Based on the identification code of the counting means 101, a recording area is secured for each counting means 101, and the number of people of the counting means 101 corresponding to the corresponding place is stored in the data creation holding means 408 based on the identification code of the counting means 101. Data and re-corrected timekeeping time are retained. Therefore, even if data is collected by a plurality of portable terminals 301, these data can be collectively managed by the data aggregation means 401.

  The communication performed between the data transmission unit 309 and the data reception unit 406 may be wired or wireless, similar to the communication performed between the portable terminal 301 and the counting unit 101.

  The counting means arrangement drawing holding means 407 holds an arrangement drawing showing the arrangement of the counting means 101 in a map of a single or a plurality of specific areas to be calculated. Then, the number of persons in the specific area is calculated from the number of persons data using a calculation method determined based on the layout drawing. The calculation result is displayed on the display means 409, or the output means 404 outputs a hard copy or digital data to another device.

  The arrangement drawing held by the counting means arrangement drawing holding means 407 will be specifically described. FIG. 5 is a diagram showing an example of an arrangement diagram held by the counting means arrangement drawing holding means 407. In the layout shown in the figure, H, I, J, and K indicate specific areas that are subject to calculation of the number of persons, and reference numerals 501 to 504 denote locations where the counting means 101 is installed (that is, counting locations). At the same time, a path that can be traversed between the areas H to K is shown. There is no other way to go back and forth.

  The counting means 101 installed at reference numeral 501 records the number of people who entered H from outside the areas H to K and the number of people who left outside the area from H for each unit time. The counting means 101 installed at reference numeral 502 includes a number of people who have moved from H to I per unit time, a number of people who have moved from I to H, a number of people who have moved from H to J, and a number of people who have moved from J to H. The number of people who moved from J to I and the number of people who moved from I to J are recorded. The counting means 101 installed at reference numeral 503 records the number of people who have moved from J to K and the number of people who have moved from K to J every unit time. The counting means installed at reference numeral 504 records the number of people who entered K from outside the area and the number of people who left outside the area from K for each unit time.

  Next, a calculation method for calculating the number of persons in each specific area, which is determined based on such a layout diagram, will be described. FIG. 6 is a table summarizing calculation methods for calculating the number of persons in each specific area corresponding to the example of the layout diagram of FIG. In this table, the number of the installation place of the counting means 101 is written in the column of the counting means, and the classification according to the passing direction counted by each counting means 101 is written in the column of the direction of human flow. In each column of the number of people from H to K, the calculation method (addition or subtraction) of the classified results is written. The column without description of the calculation method is unnecessary for calculating the number of persons in the specific area.

For example, in order to calculate the number of people H, “from outside to H” of the counting means 101 installed at reference numeral 501, “I to H” and “J to H” of the counting means 101 installed at reference numeral 502. ”And“ Counting means 101 installed at reference numeral 501 “From H to outside”, and the counting means 101 installed at reference numeral 502 “from H to I” and “From H to J”. Can be subtracted. That is, as a calculation method for calculating the number of people of H,
“From outside to H” + “From I to H” + “From J to H”
-From H to outside-From H to I-From H to J
This is the calculation method. Similarly, each person from I to K may be calculated according to the table in FIG.

  From the above, the calculation method for calculating the number of persons in the specific area specifies the direction of travel counted by the counting means 101 necessary for calculation for each specific area to be calculated based on the layout diagram, For each direction of travel, either the addition or subtraction operation method is determined, and each is added or subtracted.

  In the above description, it is assumed that the number of persons in each specific area before the start of operation of the people counting system of the present invention is zero. However, if it is not zero, this can be corrected by adding this to each area.

Next, operations of the counting unit 101, the portable terminal 301, and the data totaling unit 401 will be described.
FIG. 7 is a diagram showing a processing flow for explaining the operation of the control means 102 of the counting means 101. The counting means 101 needs to set the direction when counting the number of passers-by, for example, as shown in FIG. The operation at this time will be described with reference to FIG. 7A. A direction for counting the number of passers by the portable terminal 301 is set, and the setting result is received via the communication unit 105. (Step S711). Next, when the setting result is received in step S711, the control unit 102 sets the setting result in the calculation unit 104 (step S712).

  Moreover, the control means 102 starts the counting of the calculating means 104 based on the instruction | command which the portable terminal 301 transmits, as shown in FIG.7 (B) (step S721). Further, the control means 102 stops counting by the computing means 104 based on the command transmitted from the portable terminal 301 (step S722).

  Although the portable terminal 301 can transmit the time measured by the time measuring means 306 via the command transmission means 304, the time measured by the time measuring means 306 is received via the communication means 105 as shown in FIG. (Step S731) Then, the control means 102 sets the time measuring means 107 (Step S732). Thereby, the time of the time measuring means 107 of the counting means 101 and the time of the time measuring means 306 of the portable terminal 301 are adjusted. However, the time can be corrected by the above-described time correction process without setting the time of the time measuring means 107 shown in FIG.

  Further, the control means 102 initializes the number of people data held in the data holding means 106 to zero or a predetermined number of people as shown in FIG. 7D in response to a command from the portable terminal 301 (step S741). ).

  Further, the control means 102 transmits the number data held in the data holding means 106 to the communication means 105 through the communication means 105 in response to a command from the portable terminal 301 as shown in FIG. (Step S751). Next, when the number of people data is transmitted to the communication means 105 in step S751, the time keeping time (transmission / reception time) of the time keeping means 107 at that time is transmitted (step S752).

  Next, the operation of the data holding unit 106 will be described. FIG. 8 is a diagram showing a processing flow for explaining the operation of the data holding means 106. The data holding means repeats the processing flow shown in the figure in a cycle.

  The processing flow shown in the drawing will be described in detail. First, in step S81, it is determined whether or not there is an instruction to initialize the number of people data held by the data holding means 106. In step S81, if there is an instruction to initialize the number of people data, the process proceeds to step S82. On the other hand, if it is determined in step S81 that there is no instruction for initializing the number of people data, the process proceeds to step S83. In this step S83, it is determined whether or not the passage direction is set for the computing means 104. Then, if there is no setting of the direction of passage for the computing means 104 in step S81, the process proceeds to step S84. On the other hand, if the passage direction is set for the computing means 104 in step S83, the process proceeds to step S82.

  When the process proceeds to step S82, that is, when there is an instruction to initialize the number of people data at step S81, and when the passage direction is set to the calculation means 104 at step S83, the data holding means 106 is stored. The stored data (number data and time measured by the time measuring means 107) stored in the above are initialized. When the process of step S82 is performed, the process proceeds to step S84.

  In step S84, the presence / absence of a transmission command from the portable terminal 301 is determined. And when there is no transmission command from the portable terminal 301, it progresses to the process of step S85. In step S85, the data held in the data holding unit 106 (held data updated in step S88 described later) is transmitted to the mobile terminal 301 via the communication unit 105.

  If there is no transmission command from the portable terminal 301 in step S84, or if the number of people data is transmitted to the portable terminal 301 in step S85, the process proceeds to step S86. In step S86, the counting result in the computing means 104 is obtained. (The number of people in each direction of travel) is acquired. When the counting result is acquired in step S86, the process proceeds to step S87. In this step S87, the time measured by the time measuring means 107 is acquired. Next, when the timekeeping time is acquired in step S87, the process proceeds to step S88. In this step S88, the retained data is updated.

Next, the operation of the control unit 303 of the mobile terminal 301 will be described. FIG. 9 is a diagram showing a processing flow for explaining the operation of the control means 303.
As shown in FIG. 9A, the control unit 303 transmits a command to the control unit 102 via the command transmission unit 304 and the communication unit 105 (step S911). This command is, for example, a request to transmit the number of people data held in the data holding means, a command to start or end counting, and the like.

  The system administrator can set the computing means 104 by operating the control means 303 with the man-machine interface 302 including the pointing device while looking at the display means 305 of the portable terminal 301. The content displayed on the display unit 303 is, for example, a view overlooking the counting area as shown in FIG. 2, and area settings relating to measurement such as A to G can be performed by the man-machine interface 302. For this setting, as shown in FIG. 9B, first, setting data (for example, area setting data relating to measurement such as A to G) is created using the display unit 305 and the man-machine interface 302 (step S921). ). Next, the created setting data is transmitted to the control unit 102 via the command transmission unit 304 and the communication unit 105 (step S922).

  The control means 303 can adjust the time of the time measuring means 107, and controls the time measuring time of the time measuring means 306 to the control means 102 via the command transmitting means 304 and the communication means 105 as shown in FIG. 9C. It transmits to the means 102 (step S931). The control means 102 sets the time measuring means 107 to the time measured by the time measuring means 306 transmitted in step S931 (step S932).

  When the data held in the data holding means 106 is transmitted to the data holding means 308, a data transmission request is sent to the control means 102 via the command sending means 304 and the communication means 105 as shown in FIG. (Step S941). When the holding data held in the data holding means 106, that is, the number data and the time measured by the time measuring means 107 are transmitted via the communication means 105, the data receiving means 307 receives them (step S942). Next, the received clock time of the clock means 107 is corrected according to the correction method described above using the clock time of the clock means 107 and the clock time of the clock means 306 (step S943). Then, the received number data and the corrected timing are held in the data holding means 308 (step S944).

  Next, the operation of the control unit 403 of the data totaling unit 401 will be described. FIG. 10 is a diagram showing a processing flow for explaining the operation of the control means 403. The system administrator operates the control unit 403 via the man-machine interface 402, and the control unit 403 starts editing the layout diagram of the counting unit 101 as shown in FIG. 10A (step S101). . Since the system administrator performs an editing operation via the man-machine interface 402, the layout diagram of the counting unit 101 is updated based on the editing operation, and the result is displayed on the display unit 409 (step S102). The system administrator confirms the editing result on the display means 409 and confirms it, thereby confirming the layout of the counting means 101 (step S103). The layout of the counting means 101 is, for example, as shown in FIG. Next, the measurement direction of each counting means 101 is analyzed to determine a calculation method for calculating the number of people in the specific area (step S104). This calculation method is, for example, as shown in the table of FIG. Further, the data counting means 401 can count the number of people data collected by the portable terminal 301. At this time, the control means 403 first confirms the connection with the portable terminal 301 as shown in FIG. (Step S105). Next, the number data stored in the data holding unit 308 and the corrected time count are received via the data transmission unit 309 and the data receiving unit 406 (step S106). Then, the received corrected clock time is corrected according to the correction method described above from the clock time of the clock means 306 and the clock time of the clock means 405 (step S107). Next, the data held in the data creation and holding means 408 (number of people data and re-corrected clock time) is updated (step S108). Further, the number of persons in the specific area is calculated by a calculation method determined based on the layout drawing (step S109).

  In the number counting system of this example described above, the counting means 101 measures the number of passing people for each passing direction at the counting point.
