Description

  The present invention relates to a Web content data transmission control method and presence confirmation system. More specifically, the present invention relates to a system that makes it possible to easily know the seating status of a person to be detected via a network using www content.

  There are times when you want to know whether a person is seated at a company office. For example, when going to get a seal from someone in another department. In this case, check whether the person is in the seat by the following method.

For example, as disclosed in Japanese Patent Application Laid-Open No. 11-232198, the person (a person to be detected) is visually observed from a distance from each person's seat, or the person is present in advance using a telephone. There is a way to check. In addition, there is a method of attaching a sensor or switch to the seat and informing the presence status by lighting a lamp or displaying on an electric bulletin board.
Japanese Patent Laid-Open No. 11-232198

  However, there is a limit to the range of people that can be confirmed by directly viewing the subject. Further, in the method of using the lamp lighting or the electric bulletin board, the line of sight may be blocked depending on the installation position of the lamp or the electric bulletin board. The method of using a telephone requires an operation of making a call each time, which is quite troublesome.

  The present invention has been made in view of the problems of the background art described above, and the object of the present invention is to be able to reliably grasp the subject to be detected from his / her seat. It is to provide a simple and convenient means.

  A web content data transmission control method of the present invention is a web content data transmission control method for transmitting web content data in a web server to a request source when a web content browsing request is made via a network. The Web server is characterized in that the Web content is switched and transmitted according to second input information different from the browsing request, for example, the seating status of the person to be detected.

  The seating confirmation system of the present invention is a system that uses the above-described web content data transmission control method of the present invention, and when there is a web content browsing request via a terminal device equipped with a WWW browser and the network. A presence detection means for detecting presence information of a person to be detected apart from the browsing requester, if there is a browsing requester's browsing request, The Web content selected according to the detection result of the presence detection means is transmitted from the Web server to the terminal device.

  According to the present invention, Web content that is switched according to a second external input different from a browsing request, for example, presence information of a detection target person obtained by various sensors, according to a browsing request of a web browser, Since it is transmitted from the server, the presence status of the person to be detected can be confirmed through a web browser.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system diagram for implementing the Web content data transmission control method of the present invention, and FIG. 2 is a conceptual diagram showing the control method. This system includes a terminal device 1 that displays a www browser, for example, a personal computer, and a Web server 2 connected to the terminal device 1 via a network. The Web server 2 stores a plurality of Web content data (for example, content A, content B, content C, etc.). The Web server 2 switches the content to be transmitted according to external input information different from the browsing request transmitted from the terminal device 1 such as on / off information by sensors or switches.

  In this system, a predetermined content is displayed on the www browser of the terminal device 1 by the procedure shown in FIG. First, the browsing requester accesses the Web server 2 from the www browser of the terminal device 1 and makes a transmission request for Web content. Upon receiving this transmission request, the Web server 2 determines external input information, selects the Web content to be transmitted, and transmits the selected Web content to the terminal device 1. The www browser on the terminal device 1 that has requested browsing displays the transmitted Web content.

  The Web content data to be switched and transmitted may be the entire content data constituting the Web content, or a part of the content data constituting the Web content, for example, a part of the image data or a part of the character data.

  In this system, the browsing requester can know what external information has been input by the Web content displayed on the terminal device 1. For example, sensor / switch on / off information can be used as the external input information. Therefore, as described below, if the presence status of a specific person is detected as on / off information such as a sensor, whether or not a specific person away from the detection requester (viewing requester) is present, This can be easily determined by browsing the browser of the terminal device 1.

  FIG. 3 is a configuration diagram of the presence confirmation system of the present invention that uses the presence information of the person to be detected as external input information. The presence confirmation system includes a terminal device 1 (for example, a personal computer) having a www browser, and a Web server 2 connected to the terminal device 1 via a network. The Web server 2 includes a Web content storage unit 3 that stores a plurality of Web content data (content A, content B, and content C), an external information input unit 5 that acquires presence information of the detection target person, And a Web content transmission determination unit 6 that selects content data to be transmitted to the terminal device 1 based on information from the information input unit 5. Web content data corresponds to input external information. For example, content data indicating presence is stored in the Web content A, and content data indicating absence is stored in the Web content B.

  In this system, a detection requester accesses the Web server 2 from a www browser of the terminal device 1 and makes a transmission request for Web content. Specifically, the URL of the presence confirmation system is accessed. The Web content transmission determination unit 6 selects Web content data to be transmitted in accordance with the external information acquired by the external information input unit 5 and transmits it to the terminal device 1 that has requested browsing through the network unit 4. For example, if the person to be detected is present at the time of the browsing request, the Web server 2 selects the Web content A indicating that it is present and transmits the content data. If it is absent, the Web server 2 selects the Web content B indicating the absence and transmits the content data.

  Various means can be considered as the presence detection means for acquiring the presence information of the person to be detected. In the presence confirmation system shown in FIG. 4, a human body temperature detection unit 5 a including a temperature sensor is provided. The human body temperature detection unit 5a is installed in the vicinity of the sitting position of the person to be detected, and measures, for example, the temperature near the seating surface of the chair or the backrest. The external information input unit 5 determines the presence status of the detection subject from the measurement result of the human body temperature detection unit 5a.

  The presence confirmation system shown in FIG. 5 includes a distance measuring unit 5b configured by a distance sensor. The distance measuring unit 5b is installed in the vicinity of the person to be detected, and continuously measures, for example, the distance to the seating surface of the chair and the distance to the backrest. The external information input unit 5 determines the presence status of the person to be detected from the distance measured by the distance measuring unit 5b.

  The presence confirmation system shown in FIG. 6 includes a human body temperature detection unit 5a composed of a temperature sensor and a distance measurement unit 5b composed of a distance sensor. The external information input unit 5 determines the presence status of the person to be detected from the temperature obtained by the human body temperature detection unit 5a and the distance obtained by the distance measurement unit 5b. Since a plurality of detection means having different measurement methods are used, a system in which the presence status can be grasped more reliably and misidentification is reduced is constructed.

  As long as the presence detection means in these systems can grasp the presence or absence of a human body, the type of sensor used is not limited. For example, a pyroelectric sensor is an example of the temperature sensor.

  FIG. 7 is a block diagram of the external information input unit 5 in the presence confirmation system using the pyroelectric sensor. The pyroelectric sensor 7 detects a change in the distribution of the amount of infrared energy caused by the movement of the human body within the sensor visual field. The external information input unit 5 detects the movement of the human body from the distribution change and determines the presence status of the detection target person. Therefore, when the detection target person is seated and does not move, the presence / absence of the human body cannot be detected, and the external information input unit 5 may fall into an unknown state. The external information input unit 5 shown in FIG. 7 is configured to avoid this situation. The external information input unit 5 includes a pyroelectric sensor 7, a timer control unit 8 including a detection continuation timer 8 a and a detection continuation time change timer 8 b, and the output change of the pyroelectric sensor 7 and the timer control unit 8 The presence or absence of the human body is determined from the two timer operations. That is, the presence / absence of the person to be detected is determined by detecting the timing at which the output value from the pyroelectric sensor 7 changes.

  The detection continuation timer 8a measures the elapse of a predetermined time, and if it detects an ON signal from the pyroelectric sensor 7 during the measurement, the external information input unit 5 outputs the detection determination signal as ON. To do. Then, the elapsed time is reset by the ON output from the pyroelectric sensor 7 and the start of remeasurement is repeated. Thereby, the detection continuation timer 8a is always operating with respect to the ON signal from the pyroelectric sensor 7, and the ON state of the detection determination signal is continued. The detection duration change timer 8b also measures the elapse of a predetermined time, and resets and re-measures if a certain time elapses during the measurement regardless of the ON output of the pyroelectric sensor 7. To start. And if the detection continuation timer 8a is operating when the fixed time has elapsed, the reset time of the detection continuation timer 8a is changed.

  FIG. 8 is an explanatory diagram showing an example of the operation in the external information input unit 5 and shows a state in which the person to be detected is seated from a state where he / she is away (absent state). The pyroelectric sensor 7 outputs an ON signal once in accordance with the movement of the human body. For example, a measurement time of 10 seconds is set in the detection continuation timer 8a as an initial setting. For example, a measurement time of 30 seconds is set in the detection duration change timer 8b as an initial setting. First, when both the timers 8a and 8b are stopped (absent, detection detection signal is OFF), and there is an ON output from the pyroelectric sensor 7 (time t1), the detection continuation timer 8a and the detection Each of the duration change timers 8b starts measuring elapsed time (either countdown or countup may be used). At this time, the external information input unit 5 turns on and outputs the detection determination signal. Next, if there is an ON output from the pyroelectric sensor 7 while the detection continuation timer 8a is in operation (within 10 seconds after the start of operation) (time t2), the detection continuation time change timer 8b is in operation, so external information The input unit 5 continues to output the detection determination signal as ON. Then, the detection continuation timer 8a resets the elapsed time and starts counting down again. Furthermore, if there is an ON output from the pyroelectric sensor 7 while the detection continuation timer 8a is in operation (time t3), the detection duration change timer 8b is still operating at this time, so that the external information input unit 5 determines the detection. The signal is continuously turned on and output. In this way, while the detection duration change timer 8b is operating, the detection determination signal is turned on regardless of the output of the pyroelectric sensor 7, and the detection target person is seated. I can judge. This is because there is an ON output from the pyroelectric sensor 7 at a relatively high frequency in the seated state.

  In this case, as shown in FIG. 9, when the detection continuation timer 8a is stopped while the detection continuation time change timer 8b is operating, the external information input unit 5 determines that the person to be detected has left. Turn off the detection judgment signal. Thereafter, when the absence state continues, both the detection continuation timer 8a and the detection continuation time change timer 8b are stopped, and the detection determination signal is maintained in the off state. Then, when there is an ON output from the pyroelectric sensor 7, the state returns to the initial state, and the external information input unit 5 outputs the detection determination signal as ON.

  As shown in FIG. 10, when the detection duration change timer 8b is stopped while the detection continuation timer 8a is operating (between time t3 and time t4), another new measurement time is added to the detection continuation timer 8a. (In the figure, a measurement time of 30 seconds = a measurement time set in the detection duration change timer 8b) is set. If there is no ON output from the pyroelectric sensor 7 within the new measurement time, it is determined that the person to be detected is away and the detection determination signal is output as OFF. In FIG. 10, since the detection continuation timer 8a is operating, the detection determination signal is on. Thereafter, if the detection continuation timer 8a stops, the detection continuation time change timer 8b is stopped, so the detection determination signal is turned off, the initial measurement time (10 second measurement time) is set again, and the initial state is set. Return. In this way, the external information input unit 5 detects the seated state from the seated state of the person to be detected. In this embodiment, the measurement time of the detection continuation timer 8a is changed by the operation of the detection continuation time change timer 8b. As a result, the human body moves greatly when seated from absence, but the motion becomes small when seated and the risk of misjudging as absent is reduced.

  The presence confirmation system shown in FIG. 11 includes an ultrasonic sensor unit 5c configured by an ultrasonic sensor. The ultrasonic sensor unit 5c is installed in the vicinity of the detection target person, emits ultrasonic waves from the ultrasonic transmission unit (not shown) toward the detection target person, and receives the reflected ultrasonic wave (see FIG. (Not shown) to determine the presence status of the person to be detected. In this way, it is possible to determine the presence status of the person to be detected using ultrasonic waves.

  In the presence confirmation system shown in FIG. 12, a switch input unit 5d is further provided as a presence detection unit in order to know the seating status of the person to be detected. The switch input unit 5d uses an electric circuit, and includes, for example, a pressure-sensitive switch installed on a seating surface of a chair, a manual power switch of a person to be detected, and the like. The latter power switch is likely to cause an erroneous determination because it requires the subject person's own operation. Therefore, in the present invention, a means that can be detected by the sitting motion of the person to be detected like the former is preferable.

  The presence confirmation system shown in FIG. 13 further includes a power input determination unit 9 in addition to the above systems. The power input determination unit 9 detects whether or not the power input of a terminal device (not shown) (for example, a personal computer) assigned to the detection target person is on.

  The Web content transmission determination unit 6 selects the Web content to be transmitted in consideration of the output from the power input determination unit 9. That is, when the output from the power input determination unit 9 is on, the Web server 2 switches the Web content according to the input from the external information input unit 5 and transmits it. Of course, if the output from the power input determination unit 9 is off, the web server 2 transmits the web content corresponding to the power input as the power input is off.

  As the power input determination unit 9, specifically, for example, an Internet Control Message Protocol (ICMP) ping command is used. The ping command issues a command to a device having an IP address on the network and detects its response. Therefore, the terminal device of the person to be detected needs to be connected to the terminal device 1 of the requester of detection (viewing requester) via the network, and an IP address unique to the person to be detected needs to be set.

  This procedure will be described with reference to FIG. 14. First, a ping command is transmitted from the terminal device 1 of the detection requester to the terminal device of the person to be detected. If there is a response from the target device, it is determined that the power of the terminal device 1 of the detection target person is on. Further, if there is no response and a predetermined time elapses and a time-out occurs, it is determined that the terminal device of the detection target person is off.

  By checking the power input of the terminal device assigned to the person to be detected in this way, it is possible to grasp not only the seating status but also the attendance status to the company, etc., and whether it is temporarily absent or not .

  In the system of FIG. 15, the Web server 2 includes a mail transmission unit 10 in addition to the Web content transmission determination unit 6 that switches content to be transmitted by external input information. The external information input unit 5 can detect not only the presence / absence status of the person to be detected, but also a change in situation due to being away or seated. This e-mail transmission unit 10 detects a change in the situation from absence to seating, and notifies the e-mail that the person to be detected has been seated at the e-mail address of the browsing requester set in advance from the network unit 4. To send. The e-mail address of the browsing requester is set in the e-mail transmission unit 10 when the person to be detected is absent at the time of the browsing request.

  In this presence confirmation system, the viewing requester can know the seating information of the viewing requester by e-mail after confirming the absence. As a result, the person to be detected can be visited simultaneously with the mail delivery. Of course, as a precaution, the user may confirm the presence by making a browsing request again.

  Note that the external input information unit 5 can detect a change in the situation of having been seated from the absence state or from the seated state, so that the viewing requester is notified by e-mail that the user has left the seat. May be.

  In the presence confirmation system shown in FIG. 16, a program (automatic update unit) 11 for automatically updating content is set in the content stored in the Web server 2. The web browser is not automatically updated once the web content requested to be browsed is displayed, and the same content remains displayed unless requested by the browsing requester. Therefore, in this system, the content to be displayed on the browser is automatically updated, thereby eliminating the need for a second browsing request.

  As the automatic updating unit 11, for example, a program that transmits a Web content retransmission request to the Web server 2 toward the Web server 2 is stored in the transmitted Web content data. This program makes a browsing request to the Web server 2 at regular intervals by a timer after the Web content is displayed on the browser.

  As the automatic update means 11, it is also conceivable that the external information input unit 5 detects a change from the absence state to the presence state and sets a program for transmitting a browsing request in the Web content data.

  In the system shown in FIG. 17, an external information storage unit 12 is provided in addition to the external information input unit 5. The external information storage unit 12 stores the output from the external information input unit 5 regardless of the browsing request from the detection requester, and stores the seating status of the detection target person. Then, the Web content transmission determination unit 6 selects content data to be transmitted from the Web content storage unit 3 according to the seating situation stored in the external information storage unit 12 and transmits it to the terminal device 1.

  In this system, since the Web content to be transmitted immediately without waiting for the input from the external information input unit 5 is selected, it is possible to respond to the browsing request from the detection requester at high speed.

  The system described so far is based on the assumption that there is only one person to be detected, but a system for a plurality of persons to be detected can also be constructed. FIG. 18 is a configuration diagram illustrating an example of a system for a plurality of detection target persons.

  Here, for each detection target person, the detection target person terminals B, C, D provided with the Web server 2 and the presence detection means (not shown) as described above are connected to each detection target person B, Assigned to C and D. Each of the detection target person terminals B, C, and D has a unique URL, and the detection target person terminal B and the detection target person terminals C, D have a parent-child device relationship. And the to-be-detected person terminal B stores the to-be-detected person list linked as the slave unit information, and the links are pasted to each other.

  In this system, the detection requester first accesses the URL of the detected responder terminal B, which is the parent device, from the terminal device 1. The terminal B transmits a detection target person list to the terminal device 1, and the detection requester selects a detection target person whose presence is to be confirmed from the list. When a target person to be detected, for example, C is selected, the web content indicating the presence status of the target person C to be detected is displayed on the browser of the terminal device 1A.

  In this system, since the detection target person terminals C, D, E... Which are slave units are provided in a form linked to the detection target person terminal B which is the master unit, mutual link connection can be easily performed. It is easy to build an attendance confirmation system for multiple people. Of course, a plurality of detected person terminals B, C, D,... May be provided, and the detection requester A may directly access the URLs of the terminals B, C, D,.

  As described above, according to the present invention, the presence state of a person to be detected who is in a position that cannot be seen by the detection requester can be easily confirmed from the terminal device at hand of the detection requester.
