Description

  The present invention relates to a habit monitoring system, and in particular, notifies when a monitoring subject goes out of the monitoring area while receiving a radio wave of a transmitter attached to the monitoring subject with a receiver arranged in the monitoring area. It relates to the monitoring system.

  In recent years, a technique for responding to a person with a habit going out from a residence or staying facility has spread. For example, when a monitoring target person having a transmitter with a built-in GPS function goes out of a facility, a soot search system is known that quickly protects a person by showing the position on a map screen. In this case, the GPS function alone cannot immediately recognize that the person to be monitored has left the facility, and the system installation cost tends to be excessive. A soot monitoring system in which the control means built in the receiver notifies the person in charge of protection with a reporting means such as a buzzer when it goes out of the possible monitoring area has come to be used.

  In the soot monitoring system combining the transmitter and the receiver in this way, it is normal that the radio wave is transmitted intermittently at a predetermined interval in order to secure the battery life of the transmitter. When the radio wave of the transmitter cannot be received for a predetermined time exceeding the transmission interval, it is determined that the transmitter has gone out of the monitoring area together with the monitoring subject, and the notification means is activated.

  In addition, the range in which the receiver can receive radio waves from the transmitter is usually about several tens of meters. However, there are cases where large facilities that exceed the range cannot receive the signal even in the facility. Therefore, a sub-receiver that receives radio waves in the same manner as this is arranged in the range that the main receiver can receive, and the transmitter is in the monitoring area when both the main receiver and the sub-receiver cannot receive for a predetermined time or more. Japanese Patent No. 4257007 proposes a deaf person monitoring device that activates the notification means when it is determined that the device has gone outside.

  However, in the above-described conventional trap monitoring system, the control means of the receiver “determines” that the transmitter has left the monitoring area when the transmitter cannot receive the radio wave intermittently transmitted for a predetermined time or longer. Thus, a procedure for issuing a command for operating the notification means is executed, and the processing by the control means is complicated, and a processing capacity of a predetermined level or more is required. Therefore, the system development cost and the introduction cost are low. It was difficult to convert. In addition, installation of this system requires wiring work at the facility, and the person in charge of protection must manually stop the operation after recognizing the notification operation by the notification means, so the burden on the installation facility side is also increased. It was big.

  Furthermore, since the notification means attached to the receiver is a warning device such as a buzzer that can be notified in a relatively narrow range, for example, in a case where a large facility has a transmitter for each of a plurality of monitoring subjects, the warning device If there is no person in charge of protection in the vicinity of the system, it takes time to recognize the occurrence of drought, and it is not immediately known who has left the surveillance area, so it can be handled quickly and accurately. There was a difficulty that it was difficult to execute.

Japanese Patent No. 4257007

  The present invention is intended to solve the above-described problems, and overloads the installation facility side of the dredging monitoring system that can appropriately deal with when the monitoring subject goes out of the monitoring area. It is an object to provide at low cost without any problems.

Therefore, the present invention includes a transmitter attached to the person to be monitored and a receiver that receives radio waves transmitted by the transmitter, and the transmitter goes out of the monitoring area and the radio waves cannot be received or is below a predetermined intensity. The person in charge of protection that the control means built in the receiver actuates the predetermined notification means and the monitoring subject attached to the transmitter has gone out of the monitoring area due to the abnormal reception state lowered to in wandering monitoring system informs the, the transmitter is intended to intermittently transmits a predetermined radio wave at a predetermined interval, the notification means is always been assumed to perform the notification operation, the control means, normally by stopping only long predetermined time than the interval the notification operation the broadcast operation allowed temporarily canceled informing means each time it receives said radio wave Do reception state transmitters exist within the monitoring area The non-notification state is maintained while the transmitter is out of the monitoring area, and when it becomes an abnormal reception state, the notification state is established without stopping the transmitter. did.

  In this way, whenever the control means intermittently receives radio waves, for example, by stopping the notification operation for a time slightly exceeding the reception interval, to the notification means that is configured to always perform the notification operation. As long as the machine is in the monitoring area, it is kept in a state where no notification is made, and when it goes out of the monitoring area, it is in a notification state without being stopped. By checking whether or not there is normal reception, there is no need for a complicated procedure to continuously “determine” whether or not the transmitter has gone out of the monitoring area, thereby minimizing the processing burden on the control means. In addition, if the transmitter returns to the monitoring area, reception is possible and the notification operation is automatically stopped, so that the troublesome operation by the person in charge of protection is minimized.

  When the control means receives the transmitter's radio wave, the notification operation is stopped for a predetermined time so that the transmitter is not informed while it is in the monitoring area and is not stopped by going out of the monitoring area. According to the present invention in which a notification state is set, a dredging monitoring system capable of accurately dealing with a monitoring target person outside the monitoring area is provided at a low cost without overloading the installation facility. It can be done.

It is a system configuration figure of a 1st embodiment in the present invention. It is a functional block diagram for demonstrating the function of the receiver of FIG. It is a system configuration figure of a 2nd embodiment in the present invention. It is a functional block diagram for demonstrating the function of the receiver of FIG. FIG. 4 is a system configuration diagram as an application example of the wrinkle monitoring system of FIG. 3.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the present invention, the facility where the system is installed includes the residence of the monitoring subject, and the protection staff includes the family of the monitoring subject.

  FIG. 1 shows a system configuration diagram of a wrinkle monitoring system 1A according to the first embodiment of the present invention. In this system, it is assumed that there is only one person to be monitored, and the monitoring area is relatively narrow with the residence 2 as the center. The configuration includes one transmitter (slave unit) 10 attached to a monitoring target person with a trap and a receiver (master unit) 5A that is disposed in the monitoring subject's residence 2 and receives radio waves from the transmitter 10 And.

  In this haze monitoring system 1A, the radius of about 30 m indicated by the broken line with the receiver 5A as the center is set as the monitoring area, and the radio wave of the transmitter 10 can be obtained when the monitoring subject with the transmitter 10 goes out of the monitoring area. When the receiver 5A is incapable of receiving or is in an abnormal reception state that has dropped below a predetermined strength, the receiver 5A notifies the person in charge of protection such as a family by a notification means to protect the person to be monitored. The above configuration itself is a well-known technique common to the conventional examples.

  Referring to FIG. 2 which is a functional block diagram of the receiver 5A, in the present invention, the transmitter 10 intermittently transmits a predetermined radio wave at a predetermined interval. The control means 50A of the receiver 5A Each time the radio wave of the transmitter 10 is received in the normal reception state by the receiving means 55, the notification means 57 generates a buzzer sound for a predetermined time (a time slightly longer than the reception interval by the timing generation means 52). The transmitter 10 is stopped only while the transmitter 10 is in the monitoring area, and the non-notification state is maintained. The transmitter 10 goes out of the monitoring area and is in an abnormal reception state. In this case, the notification state is set without stopping.

  As a result, in the conventional example, the complicated procedure of confirming whether or not the normal control has been received for a predetermined time or more by the control means of the receiver and continuously determining whether or not the transmitter has gone out of the monitoring area. However, in the present invention, the continuous “determination” procedure is not required, the processing is simplified, and the processing load is greatly reduced. Therefore, it is relatively easy to reduce the system development cost and installation cost, and the notification operation is automatically stopped when the transmitter 10 returns to the monitoring area. There are few things.

  In FIG. 2, each means includes not only actual parts (hardware) but also those functionally configured by software, and power supply means for supplying power to each means is illustrated. Omitted. Further, in the present embodiment, as an example of the monitoring area by the initial setting of the transmitter 10 and the receiver 5A, the radius is about 30 m (there is variation depending on the structure of the building). It is not necessary to change the radio wave intensity of the transmitter 10 or / and appropriately change the normal reception state in the receiver 5A between the state in which the reception radio wave is reduced to a predetermined intensity or lower from the inability to receive. Since it can be enlarged / reduced, the monitoring area can be set to a desired size at the time of initial setting of the system.

  Further, the radio wave transmission operation by the transmitter 10 is assumed to be about several seconds at intervals of 5 minutes in consideration of the battery life, but this interval is also desired when initializing the system according to the characteristics of the user side. It is preferable that the time can be set. In addition, although the transmitter 10 is drawn large for convenience in FIG. 1, it is actually a lightweight and compact device incorporating a very small circuit board and a button battery, for example, about 65 mm × 35 mm × 11 mm. The system is assumed to be sewn to the clothing of the person being monitored by size, and it is assumed that there will be no discomfort even if it is attached.

  On the other hand, the receiver 5A can be turned on and off by simply inserting and removing the plug into and from the outlet and can be switched to battery-powered operation, so that no wiring work is required when installing the system. Yes. For example, if the buzzer sound in the notification state is noisy, stop the receiver 5A by simply unplugging the power, or if the family who is in charge of protection moves inside the house or goes out with the person being monitored, It is also possible to carry the system as it is to operate the system at a desired location, which greatly reduces the burden at the time of system installation and system operation on the installation facility side.

  The frequency of the radio wave generated by the transmitter 10 is normally about 700 MHz in the conventional example, whereas in this embodiment, a high frequency of about 2 GHz is assumed, and the antenna can be made shorter than the conventional example. As described above, the receiver 5A and the transmitter 10 can be easily made compact, and the degree of freedom of installation in the receiver 5A is increased.

  FIG. 3 shows a system configuration diagram of a wrinkle monitoring system 1B according to the second embodiment of the present invention. In this embodiment, it is assumed that a relatively large-scale facility 3 such as a care facility monitors a plurality of visitors' traps, and a transmitter (slave device) 10a attached to each of a plurality of monitoring subjects. , 10b, 10c, 10d, 10e, 10f, a receiver (master unit) 5B that receives these radio waves, and a radio wave of each transmitter 10a,. However, a repeater 6a that transmits the same radio wave as it is to the receiver 5B without a time lag, and another repeater 6b that is disposed at a position where it can communicate with the repeater 6a and has a similar function is provided. .

  With such a configuration, the monitoring area indicated by the broken line of the receiver 5B itself in the above-described embodiment is within a radius of 30 m, but has a similar communication distance and functions as a reflector. By arranging 6a and 6b at positions within 30 m each, the monitoring area of the receiver 5B is greatly expanded beyond the original radius of 30 m. That is, even in the case of a large-sized facility 3 whose major axis side is larger than 100 m as shown in the figure, it is possible to cover all areas in the facility. Only when it goes out of all the monitoring areas shown by (5), the notification means operates as in the case of the receiver 5A.

  In the present embodiment, the receiver 5B is connected to the in-facility LAN 40 and can be connected to the Internet line 100, which is a public communication line, and the management server 20 of the system management company 4 connected to the Internet line 100. Can be communicated with. In the notification operation of the receiver 5B, a designated plurality of designated personnel possessed by a person in charge of protection such as a facility staff from the management server 20 by performing predetermined communication with the management server 20 via the Internet line 100. The communication terminal 50a, 50b is also characterized in that it includes sending a mail notifying that the person to be monitored attached to the transmitter 10d has gone out of the monitoring area.

  As a result, in the conventional example, when there is a person in charge of protection of the facility outside the area that can be notified by a notification means such as a buzzer arranged close to the receiver, the result was delayed, whereas the person in charge of protection No matter where you are, you will be notified by e-mail without delay, and you can recognize the occurrence of wrinkles in a short time, and you can expect a reliable response by using a configuration that simultaneously notifies multiple protection personnel.

  Referring to FIG. 4 which is a functional block diagram of the receiver 5B in the kite monitoring system 1B of FIG. 3, the receiver 5B includes the control unit 50B, the reception unit 55, and the timing generation unit 53 described above. Although the basic configuration is the same as that of the receiver 5A, the notification means is based on a combination of a transmission data generation means 54 that generates data to be transmitted to the management server 20 and a transmission means 59 that transmits a communication signal. It is a feature.

  In the present embodiment, the radio waves from the transmitters 10a,... Have the same identification frequency, but have individual identification information such as IDs. Can be identified. Further, the transmission data generation means 54 generates transmission data including the identification information based on radio wave identification information that cannot be received at the time of notification, and transmits the transmission data to the management server 20 via the transmission means 59. A mail for notifying the occurrence of wrinkles is transmitted in a format including information on which transmitter is out of the monitoring area.

  As a result, the person in charge of protection who has received the notification can immediately recognize who has gone out of the monitoring area, so that it is easy to perform the response accurately. In the present embodiment, the notification means including the transmission data generation means 54 and the transmission means 59 is configured to always notify all registered transmitters 10a,... And receive each radio wave. The communication terminal is configured to stop the notification operation in parallel for a predetermined time, and when one of the transmitters goes out of the monitoring area, an email including information that can identify the transmitter is designated. Is transmitted continuously at a predetermined interval, and mail transmission is stopped when the transmitter returns to the monitoring area.

  FIG. 5 shows a system configuration diagram of a wrinkle monitoring system 1C as an application example of the wrinkle monitoring system 1B described above. This system is characterized in that, in addition to the configuration of the above-described soot monitoring system 1B, web cameras 80a and 80b are connected to the receiver 5C and the relay device 6b, respectively. In this application example, although not shown, the web camera can be connected to each transmitter 10a,..., And photographed image data can be transmitted to the receiver 5C.

  That is, the image data of the facility resident photographed by the web cameras 80a and 80b is transmitted from the receiver 5C to the management server 20 via the Internet line 100, and the web provided by the management server 20 is provided. It is characterized in that a moving image based on the image data can be displayed on the screen by accessing the page with communication terminals 60a, 60b, 60c with a display owned by the family of the facility resident. In addition, when connecting a web camera to each transmitter 10a,..., Install each transmitter 10a,... At a predetermined location without being attached to the person to be monitored and secure power to the webcam. is necessary.

  Thereby, it becomes possible for the family of the facility resident to be able to remotely confirm the state of the facility resident and to easily obtain a sense of security even if they are separated. In addition, by using this function, it becomes possible for the staff of the facility and the security staff of the security company to remotely check and monitor the state of the facility, so even relatively few staff It will be easier to operate the facility while monitoring the facility 24 hours a day.

  In the above description, the case where it is assumed that the monitoring target person of the hemorrhoid monitoring system according to the present invention is an elderly person with hemorrhoids, etc., is a mental illness patient in a hospital or an infant in a kindergarten or school, Alternatively, all persons who have a possibility of hemorrhoids, such as persons with mental disabilities, can be targeted for monitoring, and the same actions and effects as described above can be expected.

  Further, in the transmitter described above, a GPS function is added in addition to the radio wave transmission function so that the transmitted radio wave includes position information, and the location of the transmitter is displayed on a map on the display screen by accessing the management server or the like. If it can be confirmed above, not only the occurrence of wrinkles but also its search can be performed. Furthermore, when each of the above-mentioned systems is implemented at a plurality of adjacent facilities, there is a concern about the problem of interference due to overlapping monitoring areas, but in this case, by applying specific security in each system, The occurrence of malfunctions can be avoided.

  As described above, according to the present invention for the soot monitoring system, it becomes possible to accurately cope with the monitoring subject when the monitoring subject goes out of the monitoring area without overloading the installation facility. Now available at low cost.
